Technical Field
[0001] The present application relates to the field of sliding doors or windows, in particular
to a damping and anti-swing moving system.
Background of the Invention
[0002] Since the sliding doors or windows are only required to be pulled along the width
direction of the door body when they are opened and closed, the door leaf or window
leaf may collide with the door frame when the sliding doors or windows are pushed
and pulled. In order to prevent the collision mentioned above, a damper may be applied
to the existing sliding doors or windows to decelerate the sliding doors and windows
to prevent collision.
[0003] Generally, the damper is fixedly connected to the door leaf of the sliding door or
the window leaf of the sliding window. When the door leaf or window leaf jumps upward,
the door leaf or window leaf drives the damper to jump upward, so that the pulley
of the damper is out of the track, which leads to a jumping gap between the damper's
pulley and the track. When the damper falls back, the pulley collides with the track,
and there lacks a shock absorbing structure on the damper, so the impact collision
brings vibration damage to the damper. Then, when the door or window is pushed or
pulled, a lower part of the door leaf or window leaf swings since a bottom of the
door leaf or window leaf is suspended, thereby leading to the instability of the movement
of the door leaf or window leaf.
Summary of the Invention
[0004] In order to overcome at least one of the defects of the prior art mentioned above,
provided in the present application is a damping and anti-swing moving system.
[0005] The technical solutions adopted by the present application to solve the problems
are as follows:
a damper, an anti-swing wheel device and a moving body;
the damper is provided on a top of the moving body; and
the anti-swing wheel device is provided on a bottom of the moving body.
[0006] Firstly, the moving body is dampened in the present application by the damper, which
effectively prevents the moving body from colliding when moving, which prevents the
damage of the moving body. Secondly, the anti-swing wheel device is in contact with
the ground, so the anti-swing wheel device plays an auxiliary load-bearing role on
the moving body. Thirdly, the friction between the anti-swinging wheel and the ground
is used for holding back the moving body, i.e., the anti-swing wheel device holds
a lower part of the moving body and prevents the moving body from swinging.
[0007] Further, the damper includes a bounce damping device and a pulley assembly; and
the bounce damping device is provided on the pulley assembly, used for eliminating
a bouncing gap and a shock impact on the pulley assembly.
[0008] In such a setup, by providing the bounce damping device on the pulley assembly, the
bounce damping device plays a role for the movement of the moving body to eliminate
a bouncing gap. The bounce damping device provides an elastic shock-absorbing function,
which may eliminate the impact vibration of the pulley assembly and prevent damage
to the pulley assembly.
[0009] Further, the bounce damping device includes a mounting base, a rotating body and
an elastic body;
the rotating body is provided in the mounting base and rotates in the mounting base;
and the elastic body is provided on a bottom of the mounting base.
[0010] In such a setup, the elastic body of the bounce damping device is provided below
the mounting base, so that the mounting base elastically abuts the elastic body when
the moving body falls, in which the moving body is cushioned by the elastic body.
Meanwhile, elastic contact between the elastic body and the mounting base may effectively
prevent the rigid collision between the mounting base and the pulley base, which may
further prevent damage from the impact of the pulley assembly.
[0011] Further, the elastic body is a spring, an elastic clamp, or an elastic sheet.
[0012] In such a setup, the applicability of the elastic body is increased due to the structural
diversity of the elastic body. Firstly, the springs provide more versatility in application
and more normalization in use, while elastic sheets and elastic clamps provide the
advantages of simple structure and easy manufacturing.
[0013] Further, the bounce damping device also includes a connecting body; an end of the
connecting body is connected to the rotating body; and an opposite end of the connecting
body is connected to the moving body.
[0014] In such a setup, the connecting body is used for connecting the rotating body to
the moving body. The connection of the connecting body, rotating body and the moving
body may adopt a threaded connection or other detachable method, so as to increase
the mounting or connecting efficiency between components.
[0015] Further, the anti-swing wheel device includes a rolling part and an adjusting assembly,
the rolling part being connected to a bottom of the moving body, the adjusting assembly
including a rebound member and an adjusting part; an end of the rebound member is
connected to the rolling part, and an opposite end of the rebound member is connected
to the moving body; and the adjusting part is provided on the rolling part, used for
adjusting a rebound amount of the rebound member.
[0016] In such a setup, the rolling part of the anti-swing wheel device plays an auxiliary
load-bearing role for the moving body. Meanwhile, the adjusting assembly of the anti-swing
wheel device may adjust the height of the rolling part through the rebound member
and the adjusting part.
[0017] Further, the rolling part includes a supporting base, a roller base and a roller;
the supporting base is connected to the moving body; the roller base is rotatably
connected to the supporting base; the roller is rotatably connected to the roller
base; and an end of the rebound member is connected to the roller base.
[0018] In such a setup, the rolling part plays an auxiliary supporting role for the moving
body, so as to ensure the smooth operation of the moving body.
[0019] Further, the adjusting part includes an adjusting member and a redirecting body;
the redirecting body is rotatably provided in the roller base; and the adjusting member
passes through the supporting base from a side of the supporting base distal to the
roller base and is movably connected to the redirecting body.
[0020] In such a setup, the adjusting part is used for adjusting the height of the roller,
which facilitates the adjustment of the height of the roller according to the actual
situation during the installation or configuration of the moving body, which also
highly facilitates the installation of the moving body, thereby ensuring the mounting
accuracy of the moving body.
[0021] Further, the adjusting member is an adjusting bolt, and the adjusting bolt is threaded
to the redirecting body.
[0022] In such a setup, the adjusting bolt may adjust the height of the roller by means
of a threaded connection, in which the threaded adjustment is characterized by a simple
structure and good adjustment accuracy.
[0023] Further, the damper also includes a damping assembly, the damping assembly including
two clamps provided in parallel, a movable block, and a damping tube; the damping
tube is provided between the two clamps; there are two movable blocks, the two blocks
being rotatably connected to two ends of the damping tube respectively; the movable
block is slidably connected to the clamp; and a top surface of the movable block is
higher than a top surface of the clamp.
[0024] In such a setup, the provision of two movable blocks provides the damper with a bilateral
dampening function, in which the versatility of the damper is increased.
[0025] Further, the pulley assembly includes a pulley base, and the pulley base is provided
between the two clamps.
[0026] In such a setup, the pulley base is clamped between the two clamps, so that the pulley
base is better secured, i.e., the pulley base and the clamps of the dampening assembly
achieve an integral connection, which ensures the stability of the overall connection
of the pulley assembly, thereby also increasing the anti-impact strength.
[0027] In summary, the damping and anti-swing moving system provided in the present application
has technical effects as follows:
- 1. Bounce damping device: the pulley assembly is provided with the bounce damping
device, and the moving body is connected to the bounce damping device through the
connecting body. When the moving body bounces, the connecting body only drives the
mounting base and the rotating body to bounce upward, and the pulley assembly and
the damping assembly do not bounce upward. Therefore, the pulley assembly may not
detach from the track, so as to eliminate a gap between the pulley assembly and the
track and ensure constant contact between the pulley assembly and the track. When
the moving body falls, the mounting base elastically abuts the elastic body, so that
the mounting base may not rigidly collide with the pulley base directly.
[0028] Additionally, the rotating body provided in the mounting base is connected to the
moving body by the connecting body. Since the mounting base elastically abuts the
elastic body, the elastic body plays a role of cushioning on the mounting base. The
rotating body in the mounting base may drive the moving body to decelerate, reducing
the collision impact at the bottom of the moving body, avoiding impact damage to the
damper and the moving body while also reducing the operating noise.
[0029] 2. Anti-swing wheel device: the rolling part of the anti-swing wheel device is in
contact with the ground so that the anti-swing wheel device plays a supplementary
role on the moving body. Additionally, the friction generated by contact between the
rolling part of the anti-swing wheel device and the ground controls and restricts
the moving body, so as to prevent a lower part of the moving body from swinging. Also,
the adjusting part is used to adjust the height of the roller, which facilitates the
adjustment of the height of the rollers according to the actual situation during the
installation or configuration of the moving body, so as to greatly facilitate the
installation of the moving body, thereby ensuring the mounting accuracy of the moving
body.

[0076] Further, the damping assembly 13 also includes a tensioning spring 134 and a clamp

embodiment, the clamp connecting part 135 is provided above the tension spring 134.
[0081] The clamp connecting part 135 is used for connection between two clamps 131, and
the clamp connecting part 135 plays a supporting and fixing role on two clamps 131,
which effectively prevents the clamps 131 from deformation during use. Additionally,
the damping tube 133 is provided in the clamp connecting part 135, and the clamp connecting
part 135 provides a restricting space for the damping tube 133, which effectively

to the door leaf or window leaf by the bottom end of the connecting body 4; the second
damper 15 is used for opening damping; and the left end of the second damper 15 extends
out of the end of the top surface of the door leaf or window leaf.
[0089] It is to be understood that two dampers should be overall located between two ends
of the top surface of the door leaf or window leaf to increase the compactness of
the overall mounting structure when the top of the door leaf or window leaf is long
enough.
[0090] Referring to Fig.1 and Fig. 2, two retaining blocks 8 used for toggling the movable
block 132 are provided above the damper, and the first damper 14 and the second damper
15 are provided between two retaining blocks 8.
[0091] In the present embodiment, the rotating body 112 is a sphere provided with a threaded
hole in the middle, and thus the connecting body 4 is a stud adapted to the threaded
hole.
[0092] In the initial state, the damping tube 133 and tension spring 134 of the first damper
14 and the second damper 15 are all extended, and two sliders of the movable blocks
132 are snap-fitted in the corresponding snap-fit slot 6 of the sliding slot 5 respectively.
Due to the gravity of the door leaf or window leaf, the mounting base 111 is pressed
against the multi-turn wave spring. Therefore, the multi-turn wave spring is compressed,
while the top surface of the upper clamp body of the mounting base 111 does not abut
the top surface of the accommodating hole.
[0093] Since the snap-fit slot 6 is bent downward, the opening of the hook groove 7 is facing
outward and sloping upwards. The highest point of the exterior side wall of the hook
groove 7 is lower than the bottom surface of the protruding platform of the retaining
block 8, and the highest point of the interior side wall of the hook groove 7 is higher
than the bottom surface of the protruding platform of the retaining block 8.
[0094] The adjusting bolt of the anti-swing wheel device 2 is adjusted so that the roller
213 is in contact with the ground. In the present embodiment, referring to Fig. 5,
the adjusting bolt is screwed into the roller base 212 to the maximum extent possible,
and the roller 213 is adjusted to the lowest position so that the bottom of the door
leaf or window leaf is highest off the ground at this moment.
[0095] Correspondingly, since the roller base 212 pulls the elastic sheet downward, the
elastic sheet is bent downward. Therefore, the elastic sheet has a tendency to pull
upward against the roller base 212, and the elastic sheet bends downward with the
greatest amount of bending at this time.
[0096] It is to be understood that if the elastic sheet is replaced with a normal spring,
then the normal spring is extended, and the spring also has a tendency to pull upward
against the roller base 212.
[0097] It is to be noted that the process of adjusting the height of roller 213 relative
to the ground is as follows: By screwing the adjusting bolt out in a direction distal
to the redirecting body 2222, the roller base 212 and the roller 213 rotate upwardly
around the hinge shaft of the roller base 212 and the supporting base 211, that is,
they move into the groove of the roller 213. The specific principle is as follows:
After the adjusting bolt is screwed out, there is a gap between a lateral surface
of the head of the adjusting bolt proximal to the stud and a lateral surface of the
vertical plate of the supporting base 211 distal to the roller base 212. The roller
base 212 is released and the elastic sheet is recovered upwardly, so the elastic sheet
drives the roller base 212 upwardly, and the position of the roller 213 is thus elevated.
In addition, the upward rotation of the roller base 212 also pulls the adjusting bolt
in the direction toward the inserting through-hole, and eventually, a side of the
head of the adjusting bolt proximal to the stud and a side of the vertical plate distal
to the roller base 212 are once again engaged. The elastic sheet stops rebounding,
and the height adjustment of the roller 213 is completed. It is to be noted that the
redirecting body 2222 is rotatably provided in the roller base 212. Thus, the adjusting
bolt follows the redirecting body 2222 as the roller base 212 rotates upward. Therefore,
there may be no jamming between the adjusting bolt and the inserting through-hole.
When the adjusting bolt is screwed out to the maximum amount, the roller 213 is in
the highest position, while the elastic sheet bends downward with the minimum amount
of bending. Since the roller 213 is in contact with the ground continuously, thus
relatively, the bottom of the door leaf or window leaf is lowest off the ground at
this moment.
[0098] The movement process of the door leaf or window leaf is as follows:
- (1) Push the door leaf or window leaf to the right to close it, and the two dampers
follow the door leaf or window leaf to the right. The interior wall surface of the
hook groove 7 of the movable block 132 at the right end of the first damper 14 abuts
against the lateral surface of the protruding platform of the right retaining block
8. The movable block 132 at the right end of the first damper 14 is detached from
the snap-fit slot 6. The opening of the hook groove 7 of the movable block 132 at
the right end of the first damper 14 is rotated upward and is in the upward-facing
opening position. The protruding platform of the right retaining block 8 is fully
snap-fitted in the hook groove 7 of the movable block 132 at the right end of the
first damper 14. Then, the door leaf or window leaf continues to move to the right.
The movable block 132 at the right end of the first damper 14 slides to the left along
the sliding slot 5. The damping tube 133 and the tension spring 134 of the first damper
14 are all retracted. The damping tube 133 of the first damper 14 dampens the door
leaf or window leaf to decelerate. When the damping tube 133 of the first damper 14
is fully retracted, the right lateral wall of the door leaf or window leaf just fits
against the interior wall of the right frame bar, and the door leaf or window completes
closing.
[0099] Since the right side wall of the door leaf or window leaf and the inner wall of the
right frame bar collide when abutting, the right end of the door leaf or window leaf
bounces upward, and the roller 213 on the right side of the bottom surface of the
door leaf or window leaf follows the upward bouncing of the door leaf or window leaf
and disengages from the ground. The door leaf or window leaf drives the mounting base
111 and the rotating body 112 through the connecting body 4 connected with the first
damper 14 to bounce upward to the upper top surface of the accommodating hole. The
multi-turn wave spring rebounds upwardly to extend. Since the connecting body 4 may
move up and down along the mounting through-hole, the connecting body 4 does not drive
the pulley base 121 to bounce upwardly, and thus the pulley 1222 is in contact with
the upper track continuously, so there is no bouncing gap between the pulley 1222
and the upper track.
[0100] When the door leaf or window leaf falls, the connecting body 4 connected to the first
damper 14 drives the mounting base 111 and the rotating body 112 back down. The mounting
base 111 squeezes the multi-turn wave spring. The multi-turn wave spring cushions
the door leaf or window leaf and prevents a direct collision between the mounting
base 111 and the bottom surface of the accommodating hole. In addition, the roller
213 on the right side of the bottom surface of the door leaf or window leaf follows
the door leaf or window leaf back down to the ground.
[0101] When the roller 213 on the right side of the bottom surface of the door leaf or window
leaf follows the door leaf or window leaf back down to the ground, the roller 213
on the right side of the bottom surface of the door leaf or window leaf collides with
the lower track, and the right side of the door leaf or window leaf bounces upward
and back down again. Therefore, the corresponding mounting base 111, the rotating
body 112, and the connecting body 4 will again follow the door leaf or window leaf
to bounce upwardly and fall back down, and the multi-turn wave spring repeats the
same process of extension and compression movement. Eventually, the roller 213 on
the right side of the bottom surface of the door leaf or window leaf again falls back
onto the lower track.
[0102] During the falling back of the door leaf or window leaf, the multi-turn wave spring
plays a load-bearing and cushioning role for the door leaf or window leaf, preventing
the impact of the falling back of the door leaf or window leaf.
[0103] (2) Push the door leaf or window leaf to the left to open it. According to the above-mentioned
descriptions, an end of the second damper 15 without the bounce damping device 11
is extended outside directly above the top surface of the door leaf and window leaf,
so the upper track is extended outside the exterior wall of the left frame bar correspondingly.
The part of the outer edge of the upper track that is on the exterior side of the
left frame bar is used for passing through an end of the second damper 15 without
the bounce damping device 11. Finally, the left side of the door leaf and window leaf
may abut against the interior wall of the left frame bar.
[0104] When the door leaf or window leaf is pushed to the left to be opened, two dampers
follow the door leaf or window leaf to move to the left. The interior wall surface
of the hook groove 7 of the movable block 132 at the left end of the second damper
15 abuts against the lateral surface of the protruding platform of the left retaining
block 8. The movable block 132 at the left end of the second damper 15 is detached
from the snap-fit slot 6. The opening of the hook groove 7 of the movable block 132
at the left end of the second damper 15 is rotated upward and is in the upward-facing
opening position. The protruding platform of the left retaining block 8 is fully snap-fitted
in the hook groove 7 of the movable block 132 at the left end of the second damper
15. Then, the door leaf or window leaf continues to move to the left. The movable
block 132 at the left end of the second damper 15 slides to the right along the sliding
slot 5. The damping tube 133 and the tension spring 134 of the second damper 15 are
all retracted. The damping tube 133 of the second damper 15 dampens the door leaf
or window leaf to decelerate. When the damping tube 133 of the second damper 15 is
fully retracted, the left lateral wall of the door leaf or window leaf just fits against
the interior wall of the left frame bar, and the door leaf or window completes opening.
[0105] Since the left side wall of the door leaf or window leaf and the inner wall of the
left frame bar collide when abutting, the left end of the door leaf or window leaf
bounces upward. The bounce damping device 11 of the second damper 15 works in the
same principle as the bounce damping device 11 of the first damper 14 for bouncing
gap elimination and bouncing shock-absorption of the left end of the door leaf or
window leaf.
[0106] Referring to Fig. 1, since the protruding platform of the right retaining block 8
snaps into the hook groove 7 of the movable block 132 at the right end of the first
damper 14 when the door leaf or window leaf is pushed right to be closed, the first
damper 14 follows the door leaf or window leaf to move to the left when the door leaf
or window leaf is pushed left to be opened. Equivalently, the movable block 132 at
the right end of the first damper 14 slides to the right under the pull of the right
retaining block 8, so the damping tube 133 and tension spring 134 of the first damper
14 are re-stretched and extended. Then, the tension spring 134 of the first damper
14 is re-stretched and extended. Finally, since the snap-fit slot 6 is bent downward,
the movable block 132 at the right end of the first damper 14 follows the slider and
slopes downward and snaps into the snap-fit slot 6. The opening of the hook groove
7 of the movable block 132 at the right end of the first damper 14 is again facing
outward and sloping upwards. The highest point of the exterior side wall of the hook
groove 7 is lower than the bottom surface of the protruding platform of the retaining
block 8, so the protruding platform of the right retaining block 8 is detached from
the hook groove 7 of the movable block 132 at the right end of the first damper 14.
Therefore, the right retaining block 8 is not blocking the movement of the door leaf
or window leaf to the left.
[0107] It is to be understood that the anti-swing wheel device 2 at the left side of the
bottom of the door leaf or window leaf works in the same way as the anti-swing wheel
device 2 at the right side of the bottom of the door leaf or window leaf.
[0108] Similarly, when the door leaf or window leaf is pushed right to be closed again,
the hook groove 7 of the movable block 132 at the left end of the second damper 15
and the protruding platform of the left retaining block 8 are also disengaged as above.
[0109] It is to be noted that since the rotating body 112 may rotate within the mounting
base 111, the connecting body 4 may follow the door leaf or window leaf to perform
a corresponding swing adjustment during the pushing and pulling process of the door
leaf or window leaf when a slight swing is occurred along with the door leaf or window
leaf along the direction of the two sides of the track, so as to avoid the jamming
of the connecting body 4.
[0110] It is to be noted that when the door leaf or window leaf is pushed left to be opened
or when it is pushed right to be closed, the upward pulling of the roller base 212
by the elastic sheet and the downward compression of the door leaf or window leaf
on the anti-swing wheel device 2 provides the roller base 212 with a tendency to rotate
upwardly around the hinge shaft of the roller base 212 and the supporting base 211.
However, since the side of the head of the adjusting bolt proximal to the stud abuts
the side of the vertical plate distal to the roller base 212, the adjusting bolt restricts
the upward rotation of the roller base 212 so as to determine the height position
of the roller base 212, and the roller 213 of the anti-swing wheel device 2 rolls
on the ground following the movement of the door leaf or window leaf.
Embodiment 2
[0111] A difference between Embodiment 1 and Embodiment 2 is the structure of the elastic
body 113. Referring to Fig. 6, the elastic body 113 is an elastic clamp 1132. In the
present embodiment, preferably, the elastic clamp 1132 is a ring-shaped elastic clamp.
The ring-shaped elastic clamp is a hollow structure with two ends raised. The accommodating
hole is inverted T-shaped. For facilitating description, the inverted T-shaped hole
is divided into an upper hole and a lower hole, the mounting base 111 and the rotating
body 112 are both provided in the upper hole.
[0112] The mounting method of the ring-shaped elastic clamp is as follows. The ring-shaped
elastic clamp snaps down to be mounted. That is, the ring-shaped elastic clamp is
pushed from a side of the inverted T-shaped accommodating hole; two ends of the ring-shaped
elastic clamp abut a bottom surface of the lower hole; the tops of the slopes extending
from the ring-shaped elastic clamp to the ends abut the turns between the upper hole
and the lower hole; the top surface of a middle of the ring-shaped elastic clamp abuts
a bottom surface of the mounting base 111; and a top of the connecting body 4 sequentially
passes through the mounting through-hole of the bottom wall of the accommodating hole
of the pulley base 121, a ring-shaped elastic clamp, and the connecting through-hole
of the lower clamp-body of the mounting base 111 and is finally connected to the rotating
body 112.
[0113] The working principle of the ring-shaped elastic clamp is as follows.
[0114] At the initial state, due to the gravity of the door leaf or window leaf, the mounting
base 111 is pressed against the ring-shaped elastic clamp. Two ends of the ring-shaped
elastic clamp are extended outward under compression.
[0115] When one end of the top of the door leaf or window leaf bounces upwardly, the door
leaf or window leaf drives the mounting base 111 and the rotating body 112 toward
the upper top surface of the accommodating hole through the connecting body 4. The
ends of the ring-shaped elastic clamp are retracted toward the middle, and the middle
part of the ring-shaped elastic clamp is raised upwardly. The roller 213 at the bottom
corresponding to the bouncing end of the door leaf or window leaf also follows the
door leaf or window leaf to slightly bounce up from the lower track. Similarly, since
the connecting body 4 may move up and down along the mounting through-hole, the connecting
body 4 may not drive the pulley base 121 to bounce upwardly, so that the pulley 1222
is always in contact with the upper track. Therefore, there is no bouncing gap between
the pulley 1222 and the upper track.
[0116] When the door leaf or window leaf falls, the corresponding connecting body 4 drives
the mounting base 111 and the rotating body 112 back down. The mounting base 111 provides
downward compression to the ring-shaped elastic clamp; the ring-shaped elastic clamp
provides elastic cushioning to the door leaf or window leaf, which prevents a direct
collision between the mounting base 111 and the bottom surface of the accommodating
hole. Additionally, the roller 213 at the bottom of the bouncing end of the door leaf
or window leaf falls back onto the lower track that follows the door leaf or window
leaf.
[0117] When the roller 213 at the bottom of the bouncing end of the door leaf or window
leaf falls back onto the lower track of the door leaf or window leaf, the roller 213
at the bottom of the bouncing end of the door leaf or window leaf collides with the
lower track again. At this time, the previously bouncing end of the door leaf or window
leaf will once again bounce upward and then fall back down. During this process, the
corresponding end of the mounting base 111, the rotating body 112, and the connecting
body 4 also follow the door leaf or window leaf to bounce upward and fall back again.
The ring-shaped elastic clamp repeats the same process of upward bouncing of the center
and downward extension of the ends. Finally, the roller 213 at the bottom of the bouncing
end of the door leaf or window leaf falls back onto the lower track again.
[0118] Similarly, it is conceivable to replace the elastic clamp 1132 with an elastic sheet,
and similarly, the elastic sheet is provided in the accommodating hole and is located
below the mounting base 111. The elastic sheet may achieve reciprocal downward pressing
and rebounding in the vertical direction. Preferably, in order to restrict the elastic
sheet, the middle part of the elastic sheet is provided with an insertion hole for
passing through the connecting body 4. The top end of the connecting body 4 is passed
through the insertion hole and is connected to the rotating body 112, so as to restrict
the elastic sheet by passing through the insertion hole, which effectively prevents
the elastic sheet from being shifted.
