SHC)ULDER SUPPORT-TYPE OF FIREWOOD CARRIER IIAVING BUIL~ IN
~RULTIPLE HANDLES AND A HOOKING COMPONENT
BACKGROUND - FIELD OF Tl IE INVENTION
i~
The present invention relates to the field of firewood carriers and is particularly
- concerned with a shoulder support-type of firewood carrier having buil~-in components
for facilitating ergonomical handling thereof.
10 BAGICGROUN!D - PRIOR ART
Firewood typically consists in three logs having a generally elongated configuration.
When the firewood is moved from one location to another, it is often carried in piles. For
example, a user may wish to carry a dozen of wood Jogs from a location situat~d outside
15 a residence to a location positioned inside the residence adjacent a flre place.
Since the logs are typically unhewned and relatively cir~ular in cross-section, some
users resort to pressing the pile of logs against their chests while carrying the latter.
~ ` ~
However, this type of practice can prove to be messy and may easily result in the
dropping of some of the logs onto the ground surFace.
Accordingly, various types of log carrying devices have be developed in order to
5 facilitate the carrying operation of firewood from one location to another.
One of the iog carrying devices introduced over the years is the so-called shoulder
support-type of firewood carrier. An example of such a device is disclosed in U.S. Patent
4,391,397 granted to William D. Taylor, Jr. on July 5~ 1983. This patent teaches a
10 firewood carrier having a pair of "S"-shaped carrying components made of tubular rigid
supporting material and arranged spaced apart in parallel planes. The upper hook portion
is covered with a padding material and is configured to be suspended from the wearer's
shoulders. Both the upper and lower portion of the device are individually "C"-shaped.
The lower portions support and form part of the receptacle in which the firewood rests.
15 Crossbar elements space and brace the "S"-shaped members and complete ~he "S"-
shaped members. The lower hook portion is preferably covered in canvas and positioned
in front of the wearer. This arrangement leaves the wearer's arm free to stack firewood
onto the carrier.
The so-called shoulder support-type of flrewood carrier suffers from a set of
drawbacks. Firstly, these types of carriers must either be loaded while the user is wearing
them as suggested in the previously mentioned patent or placed on the user's shoulder
~ .. . . -
Y l
when already loaded. If, on the one hand, a previous shoulder-type of wood carrier is
loaded when the user is wearing it, the user will have to perform various twisting and
bending movement with the firewood carrier mounted on his shoulder and partially loaded.
This type of operation ~an thus easily result in the dropping of some of the already loaded
5 firewood logs on~o the ground surface. Furthermore, this type of operation can potentially
cause severe back injuries.
If, on the other hand, the previous type of firewood carrier is mounted onto the
shoulders of the user while already loaded, the firewood carrier will need to be lifted and
10 supported while the upper hook portion is positioned on the wearer's shoulder. Again, this
type of operation co~ld potentialiy cause severe back injuries.
SlJMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an improved
shoulder-type of firewood carrier. The firewood carrier in accordance with an embodiment
of the present invention will allow for an ergonomical handling thereof.
The firewood carrier in accordance with the present invention will provide the user
20 with a variety of carrying rnode options.
The firewood carrier in accordance with the present invention will allow the user

to temporarily hang up ths firewood carrier on a hook mounted on a wall surface in order
to allow the user to load and unload the firewood carrier while the latter is positioned at
a height which facilitates its mounting over the shoulders of the wearer.
The firewood carri~r in accordance with tha present invention will conform to
conventional forms of manufacturing in order to provide a firewood carrier which will be
econGmically feasible.
In accordance with an embodiment of the present invention, there is provided a
firewood carrier for carrying logs of wood, the firewood carrier being adapted to be
reieasably hung to a wall surface, the firewood carrier being also adapted to be worn by

DET~ILFD DESCRIPTION
Referring to figure 1, there is shown a rear perspective view of a firewood carrier
10 in accordance with an embodiment of the present invention. The firewood carrier 10
has an open top and open sides substantially "U"-shaped wood receiving body 12.
The wood receiving body 12 is preferably made of a substantially flat plate of self-
supporting ma~erial which is bended so that its cross-sectional configuration assumes a
generally "U"-shaped configuration. The substantially "U"-shaped wood receiving body
12 has a substantially arcuate bottom wall 14~ A substantially straight back wall 16 and
5 a substantially straight front wall 18 extend integrally from the bottom wall 14 on opposite
sides of the latter.
A pair of substantially hook-shaped shoulder support elements 20 are rigidly fixed
to the back wall 16. The shoulder support elements 20 individually comprise a
10 subs~antially curvilinear first portion 22 and a substantially straight second portion 24
which depends integrally from the curvilinear first portion 22.
The substantially curvilinear first portions 22 are substantially "C"-shaped and form
a corresponding pair of hooks which project outwardly from the back wall 16.
A padding cushion 26 is fixed to a segment of each shoulder support element 20.
The padding cushions 26 are prsferably fixed to the interior surface of the curvilinear first
portions 22 and a fraction of the substantially straight second portion 24 by an adhesive
material such as glue. The padding cushions 26 are preferably made of a material having
20 substantially the same resiliency characteristics as rubber.
The shoulder support elements 20 are rigidly fixed to the back wall 16 by a set of
"
fixing elements such as a set of fixing bolts 28 which extend through the substantially
straight second portion 24 and into the back wall 16.
A gripping means is rigidly fixed to the substantially straight second portions 24
5 adjacent the bottom wall 14. The gripping means preferably takes the form of a pair of
side handles 30. Each side handle 30 is formed by a bended rod made of relatively rigid
material. Each side handle 30 has a substantially elongated spacing segment 32 and a
substantially elongated gripping segment 34.
The spacing segn~ents are individually flxed at one of their ends to a corresponding
substantially ~traight second portion 24. The spacing segments 32 may be fixed to the
corresponding substantially straight second portion 24 by welding lines such as the
welding lines 31.
The spacing segments 32 extend outwardly in a geometrical plane substan~ially
parallel to the back wall 16. The spacing segments 32 individually extend integrally into
the gripping segments 34. The gripping segments 34 extend outwardly, at an angle
relatively to the spacing segments 32. The gripping segments 34 extend at an angle
referred to by the reference letter A in figure 1 rela~ively to the spacing segments 32. The
20 angle A typically have a value of approximately 45 degrees.
A substantially cylindrical gripping sleeve 36 is slidably mounted over the distal end
, - . . - ,
Y l
portion of each gripping segment 34. The gripping sleeves 36 are adapted to facilitate the
prehension of the side handles 30 by providing a larger grip for the hands of a user. The
gripping sleeves 36 are preferably made of a relatlvely light and an~i-slip material such
as wood.
A top handle 38 extends across the wood receiving body 12. The top handle 38
has a generally "V"-shaped configuration formed by a s~rip of substantially flat and
bended material. The top handle 38 has a pair of dis~l top handle ends 40. The top
handle ends 40 are fixed respectively to the back wali 16 and the front wall 18 adjacent
10 an upper peripheral edge 42 ~hereof. The upper peripheral edges 40 are located opposite
the bottom wall 14.
A hooking slot 44 ~sxtends through the front wall 18 adjacent its upper peripherai
edge 42. The hooking slot 44 generally has the shape of a flattened arrow head. The
15 hooking slot 44 defin~s a substantially linear slot lower edge 46 and a substantially
inverted "V"-shaped slot upper edge 48. The inverted "V"-shaped slnt upper edge 48
defines a slot upper edge apex 49 centrally located relatively to the side edges of the
firewood carrier 10.
The hooking slot 44 is configured and sized in order to be able to receive a
hooking pin 50. The hooking pin 50 is illustrated more specifically in figure 3. The hooking
pin 50 has a generally elongated configuration. The hooking pin 50 has a hooking pin first
.. ~ ~ ~ .: , - : :- -
. . .
L
end 52 and a hooking pin second end 54. The hooking pin first end 52 has a generally
pointed configuration. The hooking pin 50 is bended adjacent the hooking pin second end
54.
In use, the firewood carrier 10 is adapted to be used ~or carrying logs of wood from
one location to another such as tha logs indicated by the referenca numeral 56 in figures
4 and 5.
Typically, although not limitavely, the logs of wood ~6 have a rel~ively elongated
configuration. The logs of wood 56 are adapted to be stacked in a pile. The logs of wood
are kept in a staoked relationship to one another by the front wall 18, the back wall 16
and the bottom wall 14 forming the substantially "U"-shaped body 12.
Once the logs 56 are stacked inside the substantially "U"-shaped body 12, the
firewood carrying device 10 is adapted to be carried by either one of two carrying
methods.
According to a flrst carrying method, a user such as the user schematized in
figures 4 and 5 and referred to by the referance numeral 58 merely grasps the top handle
38. Having grasped the top handle 3B, the user 58 then li~s the firewood carrying device
10 and carries the latter to a suitable location much like a conventional suitcase.
. .,; ; ~ ~ , ~,.. .
It should be noted that the top handle 38 also serves as a reinforcement rib for
reinforcing the structural rigidity of the firewood carrying device 10. The top handle 38
prevsnts the back wall 16 and the front wall 18 from being spaced-apart about the
bottom wall 14 by the weight of the logs ~6.
According to a second carrying method, the substantially "C"-shaped curvilinear
first portion of ~he shoulder support elements 20 are placed over the shoulders 60 of the
user 58. The shoulder support elements 20 are adapted to be engaged over the
shoulders 60 in either one of two configurations.
In a first configuration illustrated more specifically in figure 4, the shoulder support
elements 20 are engaged over the shoulders 60 of the user 58 so that the back wall 16
abuts against the back side of the user 58. In a second configuration illustrated more
specifically in figure 5, the shoulder support elements 20 are engaged over the shoulders
60 of the user 58 so that the back wall 16 abuts ~ainst the torso of the user 58.
In order to minimize the risk of injury imputable ~o the liFtin~ of a relatively heavy
wood carrying device 10 loaded with logs, the firewood carrying device 10 may be
suspended to a substantially vertical surface such as a wall indicated by the reference
2~ numeral 62 in figures 4 and 5.
In order to hang the firewood carrying device 10 on the wall 62, the hooking pin
~ -...... . ....................................... . . .

~ V c~ Y 1
50 must first have been secured to the wall 62 at a proper height relatively to the ground.
The hooking pin 50 is secured to the wall 62 by inserting the pointed hooking pin first end
52 into the wall 62. The hooking pin 50 is positioned so that the hooking pin second end
54 has its bended segment pointing substantially upwardly.
The firewood carrying device 10 is hung on the wall 62 by slidably inserting the
hooking pin 50 into the hooking slot 44. When the hooking pin 50 is inserted in the
hooking slot 44, the weight of the firewood carrying device 10 will cause the hooking pin
50 to abuttingly slide along the inclined periphery of the inverted "V"-shaped slot upper
edge 48 until the hooking pin 50 reaches the slot upper edge apex 49. The inverted "V"-
shaped configuration of the slot upper edge 48 thus allows self-centering of the firewood
carrying device 10 under its own weight. The self-centering of the firewood carrying
device 10 prevents the tilting of the latter and the consequence drop of the logs 56 which
are loaded onto the firewood carrying device 10.
One of the main features of the present invention resides in the fact that the
flrewood carrying device 10 can be loaded and unloaded while it is suspended to a wall
surface such as the wall 62. By suspending the firewood carrying clevice 10, the user is
allowed to lift individual logs and place the latter individually in the firewood carrying
20 device 10. The user is thus allowed to repetitively lift relatively light logs 56 instead of
having to lift a firewood oarrying device loaded with a stack of logs 56. This method is
thus ergonomical and less susceptible of causing injury.

Once the suspended firewood carrying device 10 has been properly l~aded with
logs 5~ stacked in the substantially "U"-shaped body 12, ~he firewood carrying device 10
can be ergonomically lifted off the hooking pin 50 and carried to a suitable location. In
order to lift the firewood carrying device 10 off the hooking pin 50, the shoulders 60 of the
5 user 58 are engaged against the shoulder support el*rnents 20. The user then lifts the
firewood carrying device 10 off the hooking pin 50 in a controlled manner with his body
in a substantially upright position and the weight equally distributad on each of the
shoulders 60. This method prevents the user 5~ from having to bend while carrying a
heavy load. When the firewood carrying device 10 has reached a proper destination, the
10latter can be hung once again to a wall 62 on a hooking pin 50 prior to the logs 66 being
unloaded individually. By hanging the wood carrying device 10 loaded with logs 56 prior
to the unloading of the latter, the user is once again prevented from bending with a
relatively heavy load and thus prevented from sustaining back injuries.
15The side handles 30 are adapted to facilitate ergonomical handling of the flrewood
carrying device 10 when it is suspended over the shoulders ~0 of the user 58. The side
handles 30 allow the user 58 to momentarily take some of the weight off his shoulders
60 while keeping user 58. As illustrated in figures 4 and 5, the side handles 30 are
positioned in order to be readily available to the user 58 wether the latter has positioned
20 the firewood carrying device 10 in abutting relation with his torso or his back portion.
The side handles 30 can be used to tilt the firewood carrying device 10 so as to facilitate
insertion of the hooking pin 50 into the hooking slot 44. The side handles 30 are also
:~ ' ' : '
adapted to b~ used to stabilize the loaded firewood carrying device 10.
