LEG-OPERATED GARDEN TOOLS
ABSTRACT
Leg-operated garden tools comprise of various interchangeable tools attached essentially to the heel
of a person' shoe. There are two distinct categories: 1.Tools operated just in the vertical direction,
which use the user's weight to do the job. Simply walking across the ground to be cultivated,
causes the tools to penetrate into the soil, carrying out different kinds of cultivation practices such
as: coring, slicing, spiking and cutting of the turf, creation of bulb-sized planting holes or
transplant holes, compression of the soil, etc. The user's weight may activate also some tools
mechanisms e.g. that of hinged shears. 2. Tools operated in the horizontal and vertical direction.
The user presses down and at the same time draws the tool either backward or forward. For soil
cultivation there are: gap cleaner, all purpose rake, single plow, double plow, cultivator, shallow
furrows maker and hoe. There is the possibility to use wheels to activate some tooling mechanisms
e.g. rotary shears, or reciprocating shears. All these tools are interchangeable being attached to the
tool attachment by a clamping system and to the heel of the shoe by various kinds of attachments
which may use a clamping and safety device. The person may wear a conventional shoe or a shoe
having secured inside the heel a clamped element of a clamping and safety device. The same tool
can be used for different shoe sizes due to the adjustable attachment. In order to achieve the desired
practice, various tools can be mounted on the same attachments and the same shoe. For the first
category, some tools may be designed also for a heavy animal to be attached to its hoof.

Description

SPECIFICATION 21 0 ~ ~ 3 ~
This invention relates to~the leg-operated garden tools and more particularly tovarious interchangeable tools attached essentially to the heel of the foot of an operator,
capable to carry out a variety of cultivation practices such as: coring, slicing, spiking or
cutting the turf, creating bulb siæd holes, earth cultivation, cutting the grass, etc.
It is common in devices for soil cultivation to use tractor devices or hand-operated
tools.
For home use, where the areas are small and the space for maneuvering is limited,
power equipment is not adaptable.
Heretofore, various manually powered devices have been provided for different turf
10 cultivation practices. Thus, for slicing and spiking the turf there are different machines
;'
having disk-mounted cutters. The cutters' penetration is produced by an additional weight
put above their axis. For good slicing, to penetrate the turf to a depth of 3 or 4 inches,
devices must be heavy enough, so they are difficult to hold and manipulate.
-j For turf aeration there are some leg operated tools such as:
Saunders U.S. Pat. No. 2,910,127 issued Oct. 27, 1959 shows a multi-tines
lawn tool. Tools of this type compress the soil around the holes and they are very difficult to
extract.
Canadian Patent Pat. No. 1056191 by Forest, issued June 12, 1979 shows a cross bar
securable to the underside of the shoes between the front of the heel and the rear of the sole, and
20 two cylindrical tubes held frictionally at each end of the said cross bar.
They are moreover unsatisfactory for an aeration operation which is very tiresome for the
3~ gardener, because the tubes are not positioned so that their center-line and the leg skeleton are in
- vertical alignment, and the penetration and extraction actions of the cylindrical tubes are difficult.
-3 The shoes cannot ever be used for something else and there are not any safety devices to protect
the user.
, , .

2~3~2
There are other hand-operated tools for soil cultivation. The disadvantages of these
kinds of tools consist in the fact that they are not productive enough, are tiresome for the
gardener (they take a lot of effort to hold and to push and draw into the earth and the
operator's energy is not rationally used) are not user friendly and cannot be used by the
, ,,~
handicapped people.
I have found that these disadvantages may be overcome by providing various
, "
interchangeable leg-operated tools comprising a tool and means for attaching said tool
. essentially below the heel of the foot of the user.
.j According to the direction in which the tool are activated, the invention consists of
.i
10 two distinct categories:
1. Tools operated just in the vertical direction.
~, 2. Tools operated in the horizontial and vertical direction.
i
The tools of the first category use the user's weight to do the job. Simply walking
,)
across the ground to be cultivated, causes the tools to penetrate into the soil, carrying out
. different kinds of cultivation practices. According to the shape of the active part of the tool,
th~ invention consists of different tools capable to core, slice, spike and cut the turf, create
~:~
bulb-sized planting holes or transplant holes, compress the soil, etc. The user's weight may
activate also some tools' mechanisms. According to this æpect, the invention consists of
hinged garden shears.
For the tools of the second category the user presses down and at the same time
draws the tool either backward or forward. According to the shape of the active part of the
~j tool, the invention consists of: gap cleaner, all purpose rake, single plow, double plow,
-~ cultivator, shallow furrows maker and hoe. There is the possibilityto use wheels to activate

garden tool, there are a lot of possible combinations to yield an assembly in relation to the
chosen solution for the tool (active part, tool body, tool holder) and for the attachment ~shoe,
tool attachment, means for attaching the tool to said shoe, etc).
For the first category, some tools may be designed to be attached to the hoof of a
heavy animal, for large surfaces. For example, horses are able to do automatically
themselves the turf aeration.
THE ADVANTAGES OF THE INVENTION consist in the fact that the leg-operated tools
~,
, proposed are:
j USEFUL:
; 10 - For the smaU surfaces, they cover a lot of soil cultivation practices such as:
~ coring, slicing spiking and cutting of the turf, making holes for transplants and/or
`, bulbs, plowing the earth, making furrows, cleaning the gap, removing the culm of
the lawn, cultivating the soil, compressing the earth, cutting the grass, etc.
COST ~FFECTIVE:
.,J
~ - They assure a good productivity for non powered tools.
.., ~i
- The turf slicing or spiking can be done during mowing time.
- They rninilI~i~ the operator's effort in gardening.
- For hard work the user can use his strongest muscles - the leg muscles - using
rationaUy his body.
- No gas or electricity is consumed.
~J GENERALPURPOSE:
- Using the same shoe, the same attachment and binding elements, the user can
~ mount different tools to do various soil cultivation practices such as: coring, slicing,
- j spiking or cutting the turf, making transplant holes, etc.
- Using an adjustable harness the any leg-operated tool can be used for any
conventional shoe.

- The clamping plate secured inside the shoe heel allows the user a big flexibility.
He is able to use the same shoe as a conventional one, without the tool.
USERFRIENDLY:
- No effort to hold the tools - the attachrnent works for the user.
5~ - No effort to push the tool into the ground - the gravity works for the user.
. - For the tools of the first category, by simply walking across the lawn and using
his weight, the user forces the tools to penetrate into the ground and execute
different practices.
- By the position of the tool's active parts in symmetrical locations and having their
- 10 axes of symmetry in the same vertical plane with the user's leg shinbone, it is not
difficult for the gardener to force the tool to penetrate into the soil.
- By simply pressing in the vertical direction, or by a simple twist movement,
the user attaches or detaches the tool, using a fast clamping attachment.
- The user can change anytime very quickly any tool - they are interchangeable.
- There is no effort for the user to extract the tools, because he uses the foot lever
in a natural movement. Further, the taper shape of the active parts of the toolsfacilitates their extraction.
7 - Working in ~e garden the user's hands are always free.
- The collecting bag allows clean up automatically of the lawn surface during the
coring practice;
J SAFETY:
- By the position of the tool's active parts in symmetrical locations and having their
axes of symmetry in the same vertical plane with the user's leg shinbone, the effort
s3 in the leg's joints, ligaments and muscles is a minimum.
. :
- This is diminished more using a plastic shoe which holds rigidly the operator's
~51 ' anlde.

- The plastic shoe assures a good rigidity in the effort direction, has a fle~ible shoe
and protects the foot and the user's calf.
- A safety device attachment, detaches automatically the tool for the
dangerous positions of the user's leg.
- The comfortable inner shoe of the plastic shoe protects the user's foot against the
.~ shocks during tool operation.
HEALTHY:
~ - They allow the user to practice a very useful and good physical exercise.
ii - They allow the user to work in the garden doing natural movements.
~;, 10 - This design concept for the leg-operated tools enables handicapped people to
~ work in the garden and to do the majority of the soil and the turf cultivations.

` The leg-operated garden tool has the structure shown in the flowchart of Figure 1
comprising a tool and means for attaching the tool to the heel of the foot of the user.
In Figures 2 and 3 are illustrated the possibilities to operate the tools attached to the
. shoe's heel. In relation to these possibilities, may be designed two distinct categories of tools:
~,,
1. Tools operated just in the vertical direction (Figure 2);
2. Tools operated in the vertical and horizontal direction (Figure 3).
. Figure 4 illustrates the possibilities to design a tool for each category. Any tool
:
~ :. comprises an active part, a body, means to hold the tool to the means for attaching the tool to
.;,
:~. 10 the heel of the foot of the user and eventually some mechanisms, see Figure 5.
The advantage of the tools of the first category consists in the fact that the operator
uses his own weight to operate the tool, so the effort of the user is minirnal. In this category
may be designed various tools having different active part such as:
~t Single conical planter S shown in Figures 6 and 7, comprising a conical active part
which is placed in line with the shinbone axis. This tool is used to make different holes in
soil having any density. at may be used to plant transplants, trees in a forest, etc.)
Multi-conic~l planter shown in Figures 8 and 9 employs many removeable
conical planters S aff~ed to a bar 6 by any kind of detachable system 7, having the
possibility to adjust the distance between the conical planters S in relation to the useis
~ 20 needs. All conical planters may be designed to have one or many conical elements Si
-s (Figures 11 and 12) threadable one to the other and/or onto the tool support 4 (Figure 10)
so that the user is able to do a variety of alternate configurations in relation to the needed
. ~
~ hole depth (see Figures 12a, b, c, d).
,:i
~ Single bulb planter shown in Figures 13 and 14 employs as active part two
;~ half conical tubes 6 and 7 connected via a hinge, and placed in line with the s~hinbone axis.
The operator's weight causes the tool penetration in the soil and creates a soil core which is
- 15-
,~ .
~,'1'

21L~8~32
extracted at the same time as the tool extraction. To eliminate the soil core, the operator pulls
the cable 10 which activates the lever 8 opening the tube by pivotal action of the rear side
half conical tube with respect to the front side one. The spring 9 closes the tube when the
operator releases the cable 10.
- Multi~bulb planter illustrated in Figures 15, 16 and 17 employs as active part
many conical tubes 12 affixed on two adjustable bars 13 and 14 secured to the tool body
. 4 by the clamp 11 using the bolts 17. The distance between the conical tubes may be
adjusted within a certain interval (maximum - minimum). For different hole depths there is
, the possibility to adjust each conical tube in the vertical direction (see Figure 16) by the
10 holes lSa, lSb, 15c and bolts 18 (see Figure 17). To be able to calibrate the top hole edge,
the plate 16 compresses the soil around the hole. Figures 18, 19 and 20 show another
variant of the multi-bulb planter where the conical tubes 19 are adjustable on the bars 20
'j which are secured to the tool body 4 by the plate 21.
Turf coring aerator shown in ~igures 21 and 22 employs as active part two
conical tubes 22 affilxed outside the heel, generally in symmetrical locations. When the
.~ tubes penetrate into the ground, they cut cylindrical plugs 23 and when they exit, they
extract cores 23 from the turf. To eliminate the cores 23, the support 24 has a hole in line
with each tube 22, having a bigger diameterthan thebiggest inner diameter of the tube. Each
~3 plug 23a is pushed out from the conical tube by the next one when the tube penetrates
20 again. The conical tubes 22 may be secured to the support 24 in any way, e.g. by spot
welding.
Collecting bug 25 shown in Figures 23 and 24 may be employed in order to
~: collect the cylindrical plugs after they are removed from the turf. This bag is attached to the
~ tool body 24 and to the useis shoe 1, so that it surrounds the shoe. The bag 25 has two
-, holes in line with the conical tubes 22, which represent the bag entrances. The bag bottom
side must be in contact with the body 24 and rigidly mounted around the entrance hole~.
. - 16-

21 ~8 ~32
The bag may have a plastic box 28 mounted on the tool body 24 to which is secured a
textile part 29 (see Figures 25 and 26). The cord 26 closes up the bag, on the opposite side,
by strangling it with a closing up element 27. The cord 26 enables the operator to handle the
bag manually whilst working, as well as empty it.
lur~edger shown in Figures 27, 28, 29 and 30 employs as active part a single
sharpened knife blade 30 generally in line with the shinbone axis placed in a longitudinal or
i transverse position with respect to the foot axis.
: Turf slicing aerator illustrated in Figures 31 and 33 employs two big v-shaped
knives 31 making deep penetrations into the ground, and slicing the turf. They may have
10 any other shape.
Turf spiking aerator shown in Figures 33 and 34 employs as active part many
;. rows of small v-shaped knives 32 making shallow penetrations into the ground, and spiking
the turf. They may have any other shape. It should be particularly pointed out that the
~s` slicing and spiking practices are employed between core cultivations for achieving similar
but less dramatic results. Since they cause only minor disruptions to the turf, they can be
employed as often as weekly during the growing season to mitigate the soil compacting
effects of traffic.
ln Figures 35 to 44 are illustrated the turf edger, turf slicing aerator, turf spiking
` ~ aerator and multi-bulb planter in the version where their active parts are mounted on the
20 opposite side of the plate on which the conical tubes for coring are welded. All these active
parts are removeable.
Soil compressor illustrated in Figures 45 and 46 employs as active part a variety
.~ of plates 33, attached to the shoe's heel, to compress the soil. In order to modify the weight,
the user may employ different numbers of plates 33. The user's weight is integrally used.

In the second category - tools operated in the vertical and horizontal direction - the
- tools may be designed to be drawn forward or backward, using the same attachment. In tbtis
- 17-

category may be:
Gap cleaner shown in Figures 47 to 50 employs as active part a vertical sharp
blade 34 to clean up the gap between the patio stones, being drawn either forward (Figures
47 and 48) or backward (Figures 49 and 50).
~`1 All-purpose rake shown in Figures 51,52 and 53 employs as active part many
rake teeth 35 mounted on a bar 36 which is attached to the shoe's heel by an elastic element
-~ 37. The all-purpose rake may be provided with special teeth which make it easy to remove
.~,
. the culm of the lawn.
, Single plow shown in Figures 54 to 57 is employed to cut and turn up the soil,
. 10 being drawn either backward (Figures 54 and 55) or forward (Figures 56 and 57).
Double plow shown in Figures 58 to 61 is employed to make furrows in the earth
- both faces, being drawn either backward (Figures 60 and 61) or forward (Figures 58 and 59).
Cultivator shown in Figures 62 to 65 is used to cultivate the soil - loosening and
.~
,~. aerating the earth. It may be drawn either forward (Figllres 62 and 63) or backward (Figures
.~, .
64 and 65).
Shallow furrows maker shown in Figures 66, 67 and 68 is employed to make
sha11ow furrows for sowing, etc. It consists of one or many v-shaped tillers 41, removeable
and secured to a cross bar 42. The bar 42 is aff~ed to the tool support by an elastic element
43. It may be drawn either forward IFigures 66 and 67) or backward (Figure 68).
Hoe shown in Figures 69 to 71 has a thin blade 44 set across the end of two bars45 welded onto the holder 46. It may be drawn either forward (Figures 69 and 70) or
backward (Figure 71).
For both tool categories may be designed tools activated by some mechanisms. For
,,
exarnple it may be various kinds of shears activated in the vertical direction (Figures 72 and
73) or using wheels which activate rotary shears (Figures 74 and 75) or wiprocating shears
(Figures 76,77 and 78).

~ Hinged shears shown in Figures 72 and 73 have the possibility to work in a
; horizontal plane (Figure 72) or in the vertical one (Figure 73), simply by turning ninety
degrees the blades 47,48, the support 49 and the bar 50 around the bar axisrelative to the
tool body 108. The pin Sl locks the blades in a suitable position. The shears are activated
by the lever 53 and the bar 50, while the shoe goes down and compresses the springs 54
and SS. When the weighting action disappears the springs open the shears.
Rotary shears shown in Figures 74 and 75 are used to cut the grass near the patio
stones in a vertical plane. They are provided with a toothed disk 56 activated by the wheel
57, which is rotated by a horizontal movement of the user's leg. The grass is cut by the
. 10 single tooth blade 58 which is affixed to the support axis 59 and does not move. The
opposite wheel 60 maintains the cutting disk 56 all the time in a plane normal to the ground.
~' Reciprocating shears shown in Figures 76, 77 and 78 are used to cut the grass
generally near the patio stones in a horizontal plane. They are provided with two
:i
reciprocating blades 61 and 63 having cutting teeth on both lateral sides. The inferior blade
61 is secured to the shear support 62. The superior blade 63 moves in the longitudinal
,~,.!
direction. It is activated by the frontal cam of the wheel 64 which moves the bar 65 affixed
to the blade 63 compressing the spring 66. The wheel 64 is activated by a horizontal
movement of the operator's leg. There is the possibility to adjust the elevation of the shears'
blades so that the user may cut the grass to different lengths. This adjustment in various
parallel positions of the shears' blades, is produced by a quadruple mechanism having one
element 67 affLxed to the shears support 62, another one 70 affixed to the tool support 75
(via bolt 78 and axle 79) and two other moveable elements 68 and 69. The elastic lever 71
secured to the moveable element 68 allows the level adjustment of the shears, when the pin
72 affixed to it, is introduced into different holes 73 made in the element 70. These shears
are active in both directions - backward and/or forward. There are two wheels 74 mounted
on the opposite side of the shears support 75 allowing the movement of the blades all the

time in a parallel plane to the ground surface. In some particular cases, an adjustable blade
support 76 may be used allowing a constant distance to be kept between the ground and the
shears' blades all along thereof.
- ' Based on the same principle any other leg-operated tool may be designed having its
active part shaped so that it can answer to a certain need.
For some tools (example all the tools used for the turf cultivation practices - coring,
slicing, spiking and turf edging, and for bulb planting) it may be more cost effective to use
removeable active parts mounted onto the same tool body (e.g. plate) like in Figures 35 to 44.
Figure 79 illustrates a synthesis comprising the various possibilities to design the
, j
10 active part of a leg-operated garden tool, and the Figure 80 shows the structure of different
collecting bags.
` Figure 81 shows different possibilities to design the body of a leg-operated garden
tool as a plate, a plate and at least a bar or any other shape illustrated in the Figures 47 to 78.
Figure 82 shows the possibilities to design the means for holding the tool to the
attachment - using directly the body of the tool or using a tool holder. Any one of these
variants assures an interchangeable holding using an interchangeable tool attachment as is
~ illustrated in Figure 83. All tools which need a horizontal movement may have the holder
: such that they can be drawn either backward and/or forward.
ln Pigure 84 is shown a holder secured to an interchangeable tool attachment by
20 some screws.
In Figures 85, 86 and 87 is illustrated a tool holder secured to an interchangeable
~ tool attachment which is a tool clamping device. Hence, the tool holder is a calibrated blade
.~ 79 having many holes 80 on the center line. The body of the tool clamping device 4b has
, two perpendicular slide guides in the longitudinal and transverse direction of the foot. The
slide guides have a "Z" shaped cross section. The pin 81 secured to the elastic blade 82
enters into the hole 80 and affLlces the holder to the tool attachment. To deitach the tool, the
- 20 -
.~
: ~ '

21~8~32
user has to press on the blade 82 to extract the pin 81 from the hole 80 and then, he can
` extract the holder 79 from the guide. Using different holes 80 the user is able to adjust the
tool with respect to his shoe's size, especially for the tools drawn backward. The structure of
a tool clamping device is illustrated in Figure 88.
The means for attaching the tool to the heel of the foot of the user comprises a shoe
and means for attaching the tool to the heel of said shoe, see Figure 89.
. The shoe may be an ordinary one or a special one - plastic shoe or work leather
shoe, see Figure 90.
The means for attaching the tool to the heel of an ordinary shoe comprise an
~ 10 adjustable harness and means for attaching the tool to said harness, see Figure 91.
,i The adjustable harness comprises at least one stopper which locates the heel of the
~ shoe in the right position with respect to the tool body and means for attaching the stopper
.`i to the user's leg, see Figure 92.
~,~ The stopper may be a plastic stopper or an adjustable sheet metal one, see Figure 93.
The means for attaching the stopper to the user's leg may be at least one binding element
: .`.~j
tied by a "Velcro" system or at least one plastic binding element tied by a "Velcro" system
or a clasp, see Figure 94. Different combinations between stoppers and binding elements
are possible to design adjustable harness. Hence, in Figure 95 is shown a sheet metal
-~ stopper 2 with a textile binding element 3 tied by a "Velcro" system. In Figure 96 is shown
20 a sheet metal stopper 2 with a plastic binding element tied by a clasp. Figure 97 shows a
plastic stopper 84 with a plastic binding element tied by a "Velcro" system. Figures 98 and
.,
99 illustrate a more safety shoe harness having a higher plastic stopper 85 with two
plastic binding elements 86 and 87 tied by a "Velcro" system or by clasps 83.
The Stoppers 2, 84 and 85 may be adjustable on the tool body 4 as is shown in
.. . .
Figure 100.
~, In Figure 101 is shown the structure of the means for attaching the tool to the heel

of a special shoe, using a clamping device. The structure of a clamping device is illustrated
in Figure 102.
Figures 103 and 104 illustrate embodiments of the invention comprising a
work leather shoe 92 and a clamping device which is also a safety device.
This attachment uses a plate 87 secured inside of the shoe heel which is clarnped
onto the body of the clamping device 88 by the clamp 89. The spring 90 presses the clamp
.. ~
- 89 to affix the tool onto the shoe. The bolt 91 adjusts the spring force. The plate 88 may be
, secured to the tool body 4 by the screws 94, (see Figure 103) or incorporated into the tool
~, body 4 (see Figure 104). To detach the shoe, the user has to twist the shoe. In this way the
clamping device works as a safety device too, detaching the user's leg when the person does
a wrong movement. The shoe can be a leather work shoe, Figures 103, 104, 105 and 106 or
a plastic one, Figures 107 and 105. The clamping plate 87 is secured inside of the shoe heel,
allowing the user a big flexibility. He is able to use this shoe 92 or the plastic shoe with or
without the tool attached. The structure of a plastic shoe is illustrates in Figure 108 and of a
- ' work leather shoe in Figure 109.
The plastic shoe (Figure 107) is high enough to protect the calf of the user's leg. It
comprises an external rigid plastic partial rear shoe, a comfortable inner shoe 103, a clamped
: plate 87 secured inside of its heel and a flexible sole 95. T'he inner shoe may be higher than
the outer one for the safety considerations. The hinged plastic cover 96 closes the shoe with
the clasp 97. The articulated rigid plastic cover 98 protects the user's foot .I'he hinge 99 and
the crawler shoe link 100 allow a natural movement to the foot. The components 96, 98,
~j, 101 and 102 are made by rigid plastic, having a safety role. T'his shoe is comfortable by
,3 using an internal shoe 103 which attenuates shocks during tool operation.
- i Figure 110 shows different possibilities to design the means for attaching the tool to
an adjustable harness. Hence, means for attaching the tool to an adjustable harness may be:
- an interchangeable and theadable tool attachment which attach the harness directly

to the tool body by some screws (see Figure 100 where 4 is the tool body);
- an interchangeable and theadable tool attachment which attach the harness directly
to the tool holder by some screws (see Figure 100 where 4 is the tool holder);
- an interchangeable tool attachment which is a tool clamping device shown in
` Figures 85, 86 and 87;
- a clamping device shown in Figure 111 and means to attach said clamping device` to the harness and to the tool. In this case the clamping device protects the user when he use
:
an ordinary shoe.
~!~ Figure 112 shoes the structure of means for attaching the adjustable harness to the
10 clamping device. The embodiments of this are illustrated in Figures 111 and 100 where 105
(Figure 111) and 4 (Figure 100) is an intermediary plate.
Figure 113 shows different possibilities of embodiments of means for attaching the
tool to the clamping device.
,~3 Figure 114 shows an interchangeable tool attachment having the body of the tool
,.13 clamping device secured to the body of the clamping device. The tool body or the tool
~.j
holder may be secured to the body of the tool clamping device.
Figure 115 shows an interchangeable tool attacihment having the body of the toolclamping device incorporated into the body of the clamping device. The tool body or the
tool holder may be secured to the body of the tool clamping device.
:~ ,
In the Figures 6 to 78, illustrating different kinds of tool embodiments, is used an
- ordinary shoe 1, an adjustable harness having a sheet metal stopper 2 and a textile binding
~i, element tied with a "Velcro" system. However, any shoe or attachment shown before
may be employed for the same tools. Hence, a variety of leg-operated tools may be design
~, combining all shown possibilities of embodiments of the tool (active palt, body, holder) and the
attachmeint ( shoe, clamping device, tool clamping device, harness, etc.).
The same principle may be employed for a leg-operated tool assembly attached to
