invention. It is to be noted that the embodiments of the present application
and features
in the embodiments may be combined if not conflict.
To effectively solve the problem of entering of wind and water from the door
having
a floor spring, a sealing solution of a door having a floor spring, which has
no lower rail,
is proposed. Atop border and left and right borders of a door frame are
designed, so that
the sealing problem of the top portion and left and right portions of the door
having a floor
spring is effectively solved. The present invention focuses on solving the
sealing between
door leaves as well as between the door leaf and the ground. Therefore, the
specific
structure of the door frame is not specifically described here.
In the present invention, by a control device arranged on the top of the door
leaf,
the stretching and retracting of the sealing material is controlled by a
connecting rod.
Thus, the sealing performance when the door leaf is closed is improved,
without
influencing the flexibility when opening the door leaf. When the door leaf is
closed, the
control mechanism drives the sealing material to stretch out by a connecting
rod and a
transmission mechanism, in order to improve the sealing performance of the
door leaf.
When the door leaf is opened, the control mechanism drives the sealing
material to return
to the original position by a spring, a tension spring and a bearing
mechanism, in order
to avoid wearing the sealing material and avoid influencing the flexibility
when opening
the door leaf.
The door having a floor spring of the present invention will be described blow
in
detail with reference to the accompanying drawings.
The present invention provides a door having a floor spring, which has high
sealing
performance. Fig. 1 is a structure diagram of an embodiment of a door having a
floor
spring. Referring to Fig. 1, the door 100 having a floor spring comprises a
door leaf 1 and
a sealing device 2. Fig. 2 is a structure diagram of an embodiment of a door
leaf 1, on
which a sealing device 2 is arranged, of the door 100 having a floor spring;

portion B of Fig. 2; and Fig. 5 is a partially enlarged view of a portion C of
Fig. 2. Referring
CA 03056839 2019-09-17
=
to the drawings, the sealing device 2 comprises a first control mechanism 21,
a first
connecting rod 22, a first sealing material 23, a second control mechanism 24
and a
second connecting rod 25. Wherein, the first control mechanism 21 and the
second
control mechanism 24 are located at two ends of a top 11 of the door leaf 1,
respectively,
to control the position of the first sealing material 23 according to the open
state and
closed state of the door leaf 1, in order to seal the door leaf 1 in different
levels; the first
sealing material 23 is located on a bottom 14 of the door leaf 1, mainly to
seal the bottom
14 of the door leaf 1; and the first control mechanism 21 is in transmission
connection
with the first sealing material 23 by the first connecting rod 22, and the
second control
mechanism 24 is in transmission connection with the first sealing material 23
by the
second connecting rod 25.
Exemplarily, in this embodiment, the first control mechanism 21 is arranged
close
to a hinged side 12 of the door leaf 1, the second control mechanism 24 is
arranged
close to an open side 13 of the door leaf 1, the first connecting rod 22 is
arranged close
to a hinged side 12 of the door leaf 1, and the first control mechanism 21 is
in fixed
connection with a first end 221 of the first connecting rod 22; and the first
sealing material
23 is located on the bottom 14 of the door leaf 1 and arranged along a width
direction of
the door leaf 1, and a second end 222 of the first connecting rod 22 is in
fixed connection
with a first end 231 of the first sealing material 23. The second connecting
rod 25 is
located on the open side 13 of the door leaf 1 and arranged along a height
direction of
the door leaf 1; and the second control mechanism 24 is in fixed connection
with a first
end 251 of the second connecting rod 25 and a second end 252 of the second
connecting
rod 25 is in transmission connection with a second end 232 of the first
sealing material
23.
Specifically, the first control mechanism 21 comprises a first pressing block
211 and
a first spring 212, the first pressing block 211 is in sliding connection with
the door leaf 1
along the height direction of the door leaf 1, and the first pressing block
211 is in fixed
connection with the first spring 212; and the first spring 211 is arranged to
stretch and
6
= CA 03056839 2019-09-17

retract along the height direction of the door leaf 1, and the first pressing
block 211 is in
fixed connection with a first end 221 of the first connecting rod 22.
When the door leaf 1 is closed, the first pressing block 211 slides downward
along
the door leaf 1 due to the effect of the top border. This drives the first
connecting rod 22
to move downward, to press down the first end 231 of the first sealing
material 23. The
sealing performance of the bottom 14 of the door leaf 1 is improved and the
first spring
212 is brought into the compressed state. After the door leaf 1 is opened,
during the
separation of the first pressing block 211 from the top border, due to the
recovery force
of the first spring 212, the first pressing block 211 rises gradually and
drives the first end
231 of the first sealing material 23 to return to the original position by the
first connecting
rod 22.
Specifically, to be convenient for the first pressing block 211 to slide
downward with
the closing of the door leaf 1, the two sides of the top of the first pressing
block 211, along
a thickness direction of the door leaf 1, may be designed as inclined planes.
For example,
the cross-section of the top of the first pressing block 211, along the
thickness direction
of the door leaf 1, may be triangular, trapezoidal, wedged, etc. Exemplarily,
the first
pressing block 211 may be optionally designed in a rhombic structure.
The first pressing block 211 may be in direct or indirect connection with the
first
connecting rod 22. As shown in Fig. 3, in this embodiment, the first control
mechanism
21 further comprises a first connecting member 213. Wherein, the first
connecting
member 213 is of a right-angled bent structure, having a horizontal end used
to connect
the first pressing block 211 and the first spring 212 and a vertical end used
to connect
the first pressing block 211 and the first connecting rod 22.
Accordingly, the second control mechanism 24 comprises a second pressing block
241 and a second spring 242, the second pressing block 241 is in sliding
connection with
the door leaf 1 along the height direction of the door leaf 1, and the second
pressing
block 241 is in fixed connection with the second spring 242; and the second
spring 242
is arranged to stretch and retract along the height direction of the door leaf
1, and the
7
CA 03056839 2019-09-17
=
second pressing block 241 is in fixed connection with a first end 251 of the
second
connecting rod 25.
When the door leaf 1 is closed until the second pressing block 241 comes into
contact with the top border, the second pressing block 241 slides downward
along the
door leaf 1 due to the effect of the top border. This drives the second
connecting rod 25
to move downward, to press down the second end 232 of the second sealing
material
23. The sealing performance of the bottom 14 of the door leaf 1 is improved
and the
second spring 242 is brought into the compressed state. When the door leaf 1
is opened,
during the gradual separation of the second pressing block 241 from the top
border, due
to the recovery force of the second spring 242, the second pressing block 241
rises
gradually to the original position and drives the second end 232 of the first
sealing
member 23 to return to the original position by the second connecting rod 25.
When the
door leaf is opened completely, the first control mechanism 21 drives the
first end 231 of
the first sealing member 23 to return to the original position, so that the
first sealing
member 23 completely returns to the original position. The flexibility in
opening and
closing the door leaf 1 is improved.
Specifically, to be convenient for the second pressing block 241 to slide
downward
with the closing of the door leaf 1, the two sides of the top of the second
pressing block
241, along the thickness direction of the door leaf 1, may be designed as
inclined planes.
For example, the cross-section of the top of the second pressing block 241,
along the
thickness direction of the door leaf 1, may be triangular, trapezoidal,
wedged, etc.
Exemplarily, the second pressing block 241 may be optionally designed in a
rhombic
structure.
The second pressing block 241 may be in direct or indirect connection with the
second connecting rod 25. As shown in Fig. 4, in this embodiment, the second
control
mechanism 24 further comprises a second connecting member 243. Wherein, the
second connecting member 243 is of a right-angled bent structure, having a
horizontal
end used to connect the second pressing block 241 and the second spring 242
and a
8
CA 03056839 2019-09-17
vertical end used to connect the second pressing block 241 and the second
connecting
rod 25.
Further, to improve the sealing performance between the door leaf and the door
frame or between two door leaves, the door 100 having a floor spring according
to the
present invention further comprises a second sealing member 26. The second
sealing
member 26 is located on the open side of the door leaf 1 and arranged along
the height
direction of the door leaf 1, mainly to seal the open side of the door leaf 1.
Specifically,
in this embodiment, the second sealing material 26 is located on the outer
side of the
second connecting rod 25 along the width direction of the door leaf 1; and the
second
sealing material 26 is in transmission connection with the second connecting
rod 25, and
the position of the second sealing material 26 in the open state and closed
state of the
door leaf 1 is controlled by the second control mechanism 24.
Specifically, a bottom end 261 of the second sealing material 26 is in fixed
connection with the first sealing material 23, and the positional movement of
the first
sealing material 23 is controlled by the second control mechanism 24 through
the
transmission connection between the second connecting rod 25 and the second
sealing
material 26.
To improve the flexibility and convenience of movement of the second sealing
material 26, the door 100 having a floor spring according to the present
invention further
comprises at least one group of transmission mechanisms 27 by which the second
sealing material 26 is in transmission connection with the second connecting
rod 25. For
example, two groups of transmission mechanisms 27 may be provided for each
second
sealing material 26, the two groups of transmission mechanisms 27 are arranged
in an
upper middle part and a lower middle part of the second sealing material 26,
respectively,
so that the second sealing material 26 is stressed uniformly.
When the door leaf 1 is closed, the second control mechanism 24 drives the
second
connecting rod 25 to move downward. During the downward movement of the second
connecting rod 25, the second sealing material 26 is driven by the
transmission
9
CA 03056839 2019-09-17
mechanism 27 to move outward along the width direction of the door leaf 1, so
as to
improve the sealing performance of the open side of the door leaf 1.
Specifically, the transmission mechanism 27 comprises a first transmission
member
271 in fixed connection with the second connecting rod 25 and a second
transmission
member 272 in fixed connection with the second sealing material 26, and the
first
transmission member 271 is in transmission connection with the second
transmission
member 272. Exemplarily, in this embodiment, the first transmission member 271
is in
transmission connection with the second transmission member 272 by an inclined
plane.
However, the protection scope of the present invention is not limited thereto.
When the
door leaf 1 is closed, due to the effect of the door frame, the second control
mechanism
24 drives the first transmission member 271 to move downward by the second
connecting rod 25; during the downward movement of the first transmission
member 271,
due to the effect of the inclined plane in contact with the second
transmission member
272, the second transmission member 272 is forced to drive the second sealing
material
26 to move downward and also outward along the width direction of the door
leaf 1, so
as to improve the sealing performance of the open side of the door leaf 1.
To realize the transmission connection between the first transmission member
271
and the second transmission member 272 by an inclined plane, the width of the
top end
of the first transmission member 271 is greater than the width of the bottom
end, and the
width of the top end of the second transmission member 272 is less than the
width of the
bottom end. Furthermore, the degree of inclination of the inclined plane of
the first
transmission member 271 matches the degree of inclination of the inclined
plane of the
second transmission member 272. Specifically, the width of the inclined plane
of the first
transmission member 271 and the second transmission member 272 along the width
direction of the door leaf 1 is the maximum outward movement distance of the
second
sealing material 26.
The arrangement of the transmission mechanism 27 is convenient for the outward
movement of the second sealing material 26, so as to seal the open side of the
door leaf
CA 03056839 2019-09-17

1. Correspondingly, the door 100 having a floor spring may be further provided
with a
mechanism which is convenient for the returning of the second sealing material
26 to the
original position. For example, the door 100 having a floor spring may further
comprise
at least one group of bearing mechanisms 28, configured to move the second
sealing
material 26 to the original position when the door leaf 1 is opened, in order
to increase
the service life of the second sealing material 26. For example, two groups of
bearing
mechanisms 28 may be provided for each second sealing material 26, the two
groups of
bearing mechanisms 28 are arranged in an upper middle part and a lower middle
part of
the second sealing material 26, respectively, so that the second sealing
member 26 is
stressed uniformly.
Specifically, the bearing mechanism 28 comprises a first bearing member 281 in
fixed connection with the second connecting rod 25 and a second bearing member
282
in fixed connection with the second sealing material 26, and the first bearing
member
281 is in transmission connection with the second bearing member 282.
Exemplarily, in
this embodiment, the first bearing member 281 is in transmission connection
with the
second bearing member 282 by an inclined plane. However, the protection scope
of the
present invention is not limited thereto. When the door leaf 1 is opened,
during the
separation of the second pressing block 241 from the pressure of the door
frame, due to
the recovery force of the second spring 242, the second pressing block 241
drives the
first bearing member 281 to move upward by the second connecting rod 25.
During this
process, due to the effect of the inclined plane in contact with the second
bearing member
282, the second bearing member 282 is forced by the first bearing member 281
to drive
the second sealing material 26 to move upward and also inward along the width
direction
of the door leaf 1. Thus, after the door leaf 1 is opened, the second sealing
material 26
can return to the original position.
To realize the smooth transmission connection between the first bearing member
281 and the second bearing member 282 by an inclined plane, and to ensure that
the
second sealing material 26 can be driven to move inward along the width
direction of the
11
CA 03056839 2019-09-17
door leaf 1, it is required that the width of a top end of the first bearing
member 281 is
less than the width of a bottom end of the first bearing member 281 and the
width of a
top end of the second bearing member 282 is greater than the width of a bottom
end of
second bearing member 282. Furthermore, the degree of inclination of the
inclined plane
of the first bearing member 281 matches the degree of inclination of the
inclined plane
of the second bearing member 282. Specifically, the width of the inclined
plane of the
first bearing member 281 and the second bearing member 282 along the width
direction
of the door leaf 1 should be greater than or equal to the width of the
inclined plane of the
first transmission member 271 and the second transmission member 272 along the
width
direction of the door leaf 1, in order to ensure that the second sealing
material 26 can
return to the original position, thus to effectively ensure its service life.
Exemplarily, in the
embodiment shown in Fig. 5, the bearing mechanism 28 has a same structure as
the
transmission mechanism 27, but is mounted in an opposite direction.
Additionally, in the door 100 having a floor spring according to the present
invention,
to further ensure the sealing material can return to the original position
when the door
leaf 1 is opened, the door 100 having a floor spring further comprises at
least one first
tension spring 291 and at least one second tension spring 292. Wherein, the
first tension
spring 291 is arranged horizontally, and a first end of the first tension
spring 291 is in
fixed connection with the second connecting rod 25 and a second end of the
first tension
spring 291 is in fixed connection with the second sealing material 26. When
the door leaf
1 is in the closed state, with the outward movement of the second sealing
material 26
due to the effect of the transmission device 27, the first tension spring 291
is in the
tensioned state; and when the door leaf 1 is in the opened state, it is easier
and more
convenient for the second sealing material 26 to return to the original
position due to the
effect of the first tension spring 291.
The second tension spring 292 is located at the connection position of the
first
connecting rod 22 and the first sealing material 23, and arranged
horizontally. A first end
of the second tension spring 292 is in fixed connection with the first end 231
of the first
12
CA 03056839 2019-09-17
sealing material 23, and a second end of the second tension spring 292 is in
fixed
connection with the second end 222 of the first connecting rod 22.
Specifically, the door 100 having a floor spring further comprises a pin shaft
31 and
a fixation member 32, wherein the second end 222 of the first connecting rod
22 is in
fixed connection with an end of the pin shaft 31, the pin shaft 31 is arranged
vertically to
the first connecting rod 22, and the first end 231 of the first sealing
material 23 is in sliding
connection with the pin shaft 31; and the second end 232 of the first sealing
material 23
is in fixed connection with the bottom end 261 of the second sealing material
26 by the
fixation member 32. In this embodiment, the fixation member 32 is a fastening
screw.
When the door leaf 1 is closed, due to the effect of the second control
mechanism
24, the second connecting rod 25 slides downward, so that the second sealing
material
26 is driven by the transmission mechanism 27 to move outward and downward,
and
under the connection effect of the fixation member 32, the first sealing
material 23 is
driven by the second sealing material 26 to slide away from the first
connecting rod 22
along the axial direction of the pin shaft 31 and the second end 232 of the
first sealing
material 23 is driven to move downward. When the door leaf 1 is opened, due to
the
effects of the first tension spring 291 and the bearing mechanism 28, the
second sealing
material 26 moves upward and toward the second connecting rod 25, so that the
first
sealing material 23 is driven to move toward the first connecting rod 22 along
the axial
direction of the pin shaft 31 and also the second end 232 of the first sealing
material 23
is driven to move upward. Correspondingly, when the door leaf 1 is opened, due
to the
effect of the second tension spring 292, the first sealing material 23 moves
toward the
first connecting rod 22 along the axial direction of the pin shaft 31, thus to
drive the
second sealing material 26 to move toward the second connecting rod 25. This
further
ensures that the second sealing material 26 will not be exposed at the open
state of the
door leaf 1. The service life of the second sealing material 26 is ensured.
Finally, it is to be noted that the door 100 having a floor spring according
to the
present invention is applicable to both a single-leaf structure and a double-
leaf structure.
