Description

Technical Field

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

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.
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

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.
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.

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.
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.
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.
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.
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.
Further, the elastic body is a spring, an elastic clamp, or an elastic sheet.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Further, the adjusting member is an adjusting bolt, and the adjusting bolt is threaded to the redirecting body.
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.
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.
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.
Further, the pulley assembly includes a pulley base, and the pulley base is provided between the two clamps.
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.
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.

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.
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.

In a sliding door or window with two door leaves or window leaves, the outer frame of the door body of a sliding door or window includes an upper track, a left frame bar and a right frame bar, and the following description is provided in detail in terms of one of the door leaf or window leaf.
A bottom of the door leaf or window leaf is provided with two anti-swing wheel devices 2 provided symmetrically on the left and right. Preferably, two anti-swing wheel devices 2 are provided correspondingly below two dampers respectively. Specifically, two roller bases 212 of the anti-swing wheel device 2 are provided closely. Preferably, in the present embodiment, a bottom of the door leaf and window leaf is provided with grooves for mounting two anti-swing wheel devices 2; the supporting base 211 of the anti-swing wheel device 2 is connected to a top surface of the groove; and the groove plays a surrounding protection role on the anti-swing wheel device 2 and also plays a blocking or removing obstacles role when the anti-swing wheel device 2 moves.
Referring to Fig. 1 to Fig. 4, assuming that the right push of a door leaf or window leaf closes the door and the left push opens the door. A top of the door leaf or window leaf is provided with two dampers, and the two dampers are rollable and provided on the upper track of the outer frame of the door body.
For facilitating description, from right to left, two dampers are named as a first damper 14 and a second damper 15 respectively.
The first damper 14 is overall provided directly above a top surface of the door leaf or window leaf; an end of the first damper 14 provided with the bounce damping device 11 is the right end of the first damper 14; the end of the first damper 14 provided with the bounce damping device 11 is provided on the right side of the top surface of the door leaf or window leaf; the bounce damping device 11 of the first damper 14 is connected to the door leaf or window leaf by a bottom end of the connecting body 4; and the first damper 14 is used for closing damping.
An end of the second damper 15 provided with the bounce damping device 11 is the right end of the second damper 15; an end of the second damper 15 provided with the bounce damping device 11 is provided on the left side of the top surface of the door leaf or window leaf; the bounce damping device 11 of the second damper 15 is connected 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
(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.
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.
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.
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.
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.
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.
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.
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

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.
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.
The working principle of the ring-shaped elastic clamp is as follows.
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.
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.
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.
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.
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.

It should be noted that for those skilled in the art, a plurality of improvements and modifications may be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
