Description

Rebound device for damping door and pocket door Technical Field

[0001] The present application relates to the technical field of rebound devices, and in particular to a rebounder for a damping door and a pocket door. Background Art

[0002] Pocket doors, as the name suggests, conceal the door panel within a "pocket," creating a visually expansive effect within a confined space. Typically, pocket doors are concealed within the thickness of the wall, avoiding occupying external space. A rebounder is often installed within the wall, abutting against the door to facilitate its ejection.

[0003] In the related art, the rebounder usually has locking and pop-up functions, which can achieve the effect of locking the pocket door with the inside of the wall or popping out from the inside of the wall. Since most existing pocket doors have dampers, the damper can slow down the pocket door and keep the deceleration to push the pocket door until it is completely hidden and closed. When the damper and the rebounder exist at the same time, in order to prevent the damper from interfering with the rebounder, it is usually necessary to achieve the locking effect with the rebounder before the damper is started. This requires increasing the depth of the wall groove, otherwise the locked pocket door will not be able to be completely hidden in the wall, causing trouble.

[0004] Summary of the Invention

[0005] To overcome at least one of the above-mentioned drawbacks of the prior art, the present application provides a rebounder and pocket door for a damping door. The invention solves the problem of coordinated coordination between the damper and the rebounder without increasing the depth of the wall groove, thereby ensuring that the pocket door body can be completely concealed after being locked with the rebounder.

[0006] The technical solution adopted by this application to solve the problem is:

[0007] The cam is adapted to move the sliding member relative to the sliding member when the cam is in a position to move the sliding member relative to the sliding member, and the cam is adapted to move the sliding member relative to the sliding member when the cam is in a position to move the sliding member toward the sliding member.

[0008] By adopting the above solution, when the pocket door body is hidden and closed, the toggle block drives the second contact part to move to lock the sliding part and the clutch structure. At this time, the sliding part slides to the end position, and the second contact part switches to the retracted state. The toggle block continues to slide along the sliding space at a reduced speed until it stops after it abuts against the first contact part. After the pocket door body is locked with the rebounder during the process of sliding and hiding to the wall, the pocket door body still has space to move toward the first contact part, ensuring that the decelerated sliding of the damper is not affected when the door body is closed, and at the same time, the pocket door body can be completely hidden without increasing the wall groove.

[0009] Furthermore, a first assembly part is provided at one end of the rebounder housing, and a second assembly part is provided at the other end of the rebounder housing. The first assembly part and the second assembly part are used to assemble the rebounder housing in the pocket door track or on the pocket door body.

[0010] By adopting the above solution, both ends of the rebounder housing can be fixed, thereby improving the assembly stability of the rebounder housing.

[0011] Furthermore, the second contact portion includes: a snap-fit ​​rotating block, which is rotatably connected to the sliding member; and a torsion spring, which rotates the snap-fit ​​rotating block to a side protruding from the sliding member for abutting against the pocket door body or the pocket door track.

[0012] By adopting the above scheme, the pocket door body can first abut against the second contact part when hidden, pushing the pocket door body to achieve locking with the rebounder. The pocket door body can continue to drive the door body forward when it slides decelerated by the damper. At this time, the pocket door body can compress the torsion spring to rotate the latching block into the rebounder housing. When the pocket door body abuts against the first contact part, the damper on the pocket door body completes the deceleration action, and the pocket door body is completely hidden in the wall.

[0013] Furthermore, the snap-fitting rotating block includes: a rotating shaft portion, which is rotatably connected to the sliding member; a first snap-fitting edge, which is used to abut against the pocket door body or the pocket door track; and a second snap-fitting edge, which abuts against the torsion spring to push the second snap-fitting edge to rotate toward the first snap-fitting edge, so that the first snap-fitting edge rotates to the outside of the sliding member with the rotating shaft portion as the center.

[0014] By adopting the above solution, the torsion spring can ensure that the pocket door body abuts against the first clamping edge of the clamping rotating block, thereby improving the abutting force of the clamping rotating block itself.

[0015] Furthermore, the sliding member is provided with a protective slider for sliding, the sliding direction of the protective slider is consistent with the sliding direction of the sliding member, and the protective slider is located on the back side of the locking rotating block protruding from the sliding member, so that when the locking rotating block rotates to protrude from the sliding member, it will abut against the protective slider.

[0016] By adopting the above solution, the torsion spring can assist in providing the snap-in turn block with a force to rotate and protrude toward one side of the sliding part, thereby increasing the abutment force of the snap-in turn block itself and ensuring that the sliding part can be driven to slide by the snap-in turn block when the pocket door body is hidden.

[0017] Furthermore, a guide surface is provided on the side where the protection slider abuts against the locking rotating block, and the guide surface is used to push the protection slider to slide toward the blocking block along the guide surface when the locking rotating block rotates into the sliding member.

[0018] By adopting the above solution, when the locking rotating block is subjected to a large force, the guide surface can act on the sliding member, thereby protecting the locking rotating block from rotating and contracting, and protecting its own elastic contraction effect.

[0019] Furthermore, the clutch structure includes: a movable rod, one end of which is connected to the sliding member, and the other end is bent to form a locking rod; a stopping member, which is assembled at the other end of the slide rail, and has a stopping position; wherein, when the sliding member drives the movable rod to slide toward the stopping member, the locking rod can be locked or disengaged from the stopping position.

[0020] By adopting the above solution, the locking and ejecting effects of the sliding block can be achieved.

[0021] The locking member includes: a locking seat body, which has a accommodating cavity; a locking limit member, which is assembled in the accommodating cavity, and the locking limit member includes: a clamping base plate, which is clamped in the accommodating cavity of the locking seat body; a first limit member, which is arranged on the clamping base plate and is used to limit the movement direction of the locking rod when sliding; a second limit member, which is arranged on the clamping base plate and is opposite to the first limit member, and is used to cooperate with the first limit member to make the locking rod slide toward the locking position or slide out of the locking position.

[0022] By adopting the above solution, a sliding guide function can be provided for the locking rod, thereby achieving the effects of locking and sliding out smoothly.

[0023] Furthermore, the locking seat body is provided with a side mounting hole, the side mounting hole is equipped with a side mounting plate, and the side mounting hole is communicated with the accommodating cavity for installing the locking limit piece through the side mounting hole.

[0024] By adopting the above solution, it is convenient to assemble the locking limit piece from the side of the locking seat body, thereby increasing the operable space.

[0025] A pocket door comprises a pocket door body, a pocket door track and a rebounder with damping, characterized in that the rebounder shell is assembled on the upper or lower edge of the pocket door body, and a toggle block is provided in the pocket door track for abutting against the first contact portion or the second contact portion protruding from the rebounder shell; or, the rebounder shell is assembled in the pocket door track, and a toggle block is provided on the side wall of the pocket door body for abutting against the first contact portion or the second contact portion protruding from the rebounder shell, so that the pocket door body can be completely hidden in the wall without being affected by the damper.

[0026] By adopting the above solution, the damping effect of the damper can be retained without interfering with the function of the rebounder, and the pocket door body can be completely hidden.

[0027] To sum up, the rebounder and pocket door for a damping door provided in the present application have the following technical effects: the rebounder shell has a first contact portion and a second contact portion arranged at intervals. When the second contact portion abuts against the toggle block, it can drive the sliding member and the clutch structure to achieve a locking effect. The toggle block can continue to decelerate and slide along the sliding space, and can cause the second contact portion with a retraction function to retract, thereby driving the pocket door body to hide into the wall. At this time, the toggle block abuts against the first contact portion, and the rebounder and the damper can be executed separately, avoiding mutual interference between the two. The rebounder shell itself is relatively long, so the interval between the first contact portion and the second contact portion can provide the damper with a deceleration sliding space for the door body, and will not increase the depth of the door body groove.

Therefore, they cannot be understood as limiting this application.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0042] 1 to 9 , the present application discloses a rebounder for a damping door, which is applied to a pocket door body 7 with a damper, and includes a rebounder housing 1 and an elastic member 2, a sliding member 6, a stop block 3 and a clutch structure assembled in the rebounder housing 1. The rebounder housing 1 is a strip-shaped groove with openings at both ends, and a slide rail 11 is provided inside the groove along the length direction. The slide rail 11 is located slightly above the center of the groove depth, so that the groove under the slide rail 11 has a telescopic space 12 for accommodating the elastic member 2. A first assembly part 14 is clamped at one end of the rebounder housing 1, and the first assembly part 14 slides from the end of the rebounder housing 1 into the track and is then fixed by bolts. The first assembly part 14 has a clamping portion connected to one end of the elastic member 2 for realizing connection with one end of the elastic member 2; The other end of the rebounder housing 1 is slidably installed into the stop block 3 and the sliding member 6 in sequence. After the stop block 3 slides to the screw hole position, it is fixed to the rebounder housing 1 by bolts. Space for the elastic member 2 is reserved in the strip groove below the stop block 3. The other end of the elastic member 2 passes through the space below the stop block 3 and is connected to the sliding member 6, so that the initial position of the sliding member 6 is resisted by the rebound force of the elastic member 2 and the stop block 3. Finally, the clutch structure is slid into the other end of the rebounder housing 1, so that when the clutch structure is located in the slide rail 11, the clutch structure is fixed to the rebounder housing 1 by bolts. Finally, the second assembly part 15 is assembled above the clutch structure. The first assembly part 14 and the second assembly part 15 are used to assemble the rebounder housing 1 in the pocket door track or on the pocket door body 7.

[0043] In order to enable the sliding member 6 to slide when the pocket door body 7 is hidden, a toggle block 8 capable of driving the sliding member 6 is required. When the first and second assembly parts 14, 15 are fixed to the upper or lower side of the pocket door body 7, the toggle block 8 is disposed within the pocket door track. When the pocket door body 7 is opened, the toggle block 8 can drive the sliding member 6 to slide. When the first and second assembly parts 14, 15 are assembled to the pocket door track, the toggle block 8 is disposed on one side of the pocket door body 7 and can drive the sliding member 6 to slide when the pocket door body 7 is hidden and closed, thereby achieving the locking and rebounding effect of the rebounder. The first and second assembly parts 14, 15 can secure both ends of the rebounder housing 1, improving the assembly stability of the rebounder housing 1.

[0044] In this embodiment, the first assembly part 14 and the second assembly part 15 are assembled with the pocket door track, and the sliding part 6 is provided with a first contact portion 61 and a second contact portion 62. The second contact portion 62 is used to abut against the toggle block 8 of the pocket door body 7 when the pocket door body 7 is hidden and closed. The sliding part 6 can be driven to slide by the second contact portion 62, thereby achieving the locking effect of the rebounder. Therefore, the second contact portion 62 is used to play a locking function. A sliding space 13 for sliding the pocket door body 7 is reserved between the second contact portion 62 and the first contact portion 61. Specifically, the second contact portion 62 includes a snap-on turn block 6 21 and a torsion spring 622, the card-connected rotating block 621 includes a rotating shaft portion 6211, a first clamping edge 6212 and a second clamping edge 6213, the sliding member 6 is provided with a rotating groove 63 for accommodating the rotating shaft portion 6211 and a screw position for fixing one end of the torsion spring 622, the other end of the torsion spring 622 abuts against the second clamping edge 6213, the rotating shaft portion 6211 passes through the clamping spring and is inserted into the rotating groove 63, a gasket is provided between the rotating shaft portion 6211 and the rotating groove 63, and then one end of the torsion spring 622 is fixed by screwing to the screw position, at this time, the torsion spring 622 rotates the card-connected rotating block 621 to protrude from the sliding member 6 One side is used to make the first clamping edge 6212 abut against the toggle block 8 of the pocket door body 7, so that the pocket door body 7 first abuts against the second contact portion 62 when hidden. When the pocket door body 7 drives the sliding member 6 to move toward the locking member 5 through the second contact portion 62, the rotational force applied to the clamping rotating block 621 is less than the torsion of the torsion spring 622. When the pocket door body 7 moves to a locked state with the clutch device, the door body continues to move. At this time, the sliding member 6 reaches the end position and cannot continue to move forward. Therefore, the force of the door on the clamping rotating block 621 is greater than the torsion of the torsion spring 622. At this time, the clamping rotating block 621 compresses the torsion spring 622 and rotates to the rebounder Inside the shell 1, the second contact portion 62 switches to a retracted state, the sliding space 13 is opened, the toggle block 8 is no longer in contact with the second contact portion 62, and the toggle block 8 slides along the sliding space 13. During the period when the toggle block 8 slides along the sliding space 13, the damper part of the pocket door body 7 starts to move to decelerate the door body until the toggle block 8 slides to abut against the first contact portion 61. At this time, the damper completes the deceleration work of the pocket door body 7, and the pocket door body 7 is completely hidden in the wall. Thus, the locking process of the door body's rebounder and the deceleration process of the door body's damper are staggered, avoiding the situation where the two simultaneously act and interfere with each other.

[0045] In some embodiments, in order to make the abutting force of the second contact portion 62 greater, a protective slider 64 is slidingly provided on the sliding member 6, and the sliding direction of the protective slider 64 is consistent with the sliding direction of the sliding member 6, and the protective slider 64 is located on the back side of the locking turn block 621 protruding from the sliding member 6, that is, the second locking edge 6213 of the locking turn block 621 is abutted against the protective slider 64. At this time, the locking turn block 621 rotates to protrude from the sliding member 6, so that the first locking edge 6212 can provide greater force to counteract the door body when the door body is hidden, and can assist the torsion spring 622 to provide the locking turn block 621 with a force to rotate and protrude toward one side of the sliding member 6, thereby improving the abutting force of the locking turn block 621 itself, thereby ensuring the stability of the pocket door body 7 driving the sliding member 6 to move.

[0046] In some embodiments, in order to prevent the locking rotating block 621 from being unable to retract smoothly when the sliding member 6 cannot continue to move forward, a guide surface 641 is provided on the side where the protective slider 64 abuts the locking rotating block 621. The guide surface 641 is used to enable the locking rotating block 621 to be rotated into the sliding member 6, so that the protective slider 64 can be pushed along the guide surface 641 to slide toward the abutting block 3, thereby resolving the large abutting force on the locking rotating block 621 and acting on the sliding member 6 through the guide surface 641, thereby maintaining the good elastic contraction of the locking rotating block 621 itself.

[0047] In some embodiments, in order to prevent a large rigid collision between the first clamping edge 6212 of the clamping turn block 621 and the toggle block 8 of the pocket door body 7, a flexible member 65 can be provided on the first clamping edge 6212 to provide an impact buffering effect.

[0048] In this embodiment, the clutch structure includes a movable rod 4 and a locking member 5. One end of the movable rod 4 is connected to the sliding member 6, and the other end is bent to form a locking rod 41. The locking member 5 is assembled at the other end of the slide rail 11 and has a locking position 5233. The locking member 5 includes a locking seat body 51 and a locking limit member 52. The locking seat body 51 has an accommodating cavity 511, and the locking limit member 52 is assembled in the accommodating cavity 511. The locking seat body 51 is provided with a side mounting hole 512, and a side mounting plate 53 is assembled to the side mounting hole 512. The side mounting plate 53 is connected to the locking seat body 51 by locking or bolting. The side mounting hole 512 is connected to the accommodating cavity 511, and is used for installing the locking limit member 52 through the side mounting hole 512. This facilitates the assembly of the locking limit member 52 from the side of the locking seat body 51, thereby increasing the operating space. The locking limit member 52 includes a locking base plate 521, a first limiting member 522 and a second limiting member 523. The locking base plate 521 is provided with at least one locking strip 5211 for locking the locking base plate 521 in the accommodating cavity 511 of the locking seat body 51; the first limiting member 522 and the second limiting member 523 are provided on the locking base plate 521 to limit the movement direction of the locking rod 41 when sliding. The connection method of the first limiting member 522 and the locking base plate 521, and the second limiting member 523 and the locking base plate 521 is but not limited to an integral connection or a bolt locking connection. Specifically, the first limiting member 522 includes an integrally formed retaining edge 5221 and a first guide protrusion 5222 The second limiting member 523 includes a slanted plate 5231 and a second guide block 5232. The stopping position 5233 is a slanted groove in which the second guide block 5232 is recessed. The stopping position 5233 is arranged opposite to the second limiting member 523, that is, the first guide protrusion 5222 is arranged toward the slanted groove. The retaining edge 5221 is located on the side of the clamping base plate 521 facing the side mounting hole 512. The side wall of the accommodating cavity 511 away from the side mounting hole 512 is set as a fitting wall. The slanted plate 5231 is located at one end of the clamping base plate 521 facing the movable rod 4. The slanted plate 5231 is bent toward the fitting wall. A gap is provided between the slanted plate 5231 and the fitting wall so that the locking rod 41 can pass through.

[0049] When the pocket door body 7 is hidden, the toggle block 8 of the pocket door body 7 drives the sliding member 6 to move toward the locking member 5, thereby driving the movable rod 4 to move. When the locking rod 41 slides toward the locking member 5, it first contacts the inclined plate 5231 of the second limiting member 523, and then slides along the inclined plate 5231 from between the retaining edge 5221 and the second guide block 5232 until the pocket door body 7 completely enters the wall groove. At this time, there is no second limiting member 523 on the right side of the locking rod 41, and the movable rod 4 straightens itself. At the same time, the sliding block rebounds under the elastic force of the elastic member 2, so that the locking rod 41 moves along the first guide protrusion 5222 The left wall of the pocket door slides into the locking position 5233, completing the locking state of the rebounder. When the user needs to extend the pocket door from the wall to open it, the pocket door body 7 is pressed into the wall groove again. At this time, the first contact portion 61 is engaged with the toggle block 8 of the pocket door body 7. Therefore, the first contact portion 61 is used to unlock the door. The first contact portion 61 is subjected to the force of the pocket door body to move the movable rod 4 upward and hit the first guide protrusion 5222, thereby sliding to the right side of the first guide protrusion 5222, so that the locking rod 41 enters the first guide protrusion Between the right side wall of block 5222 and the fitting wall, the user releases the pressed pocket door body 7 at this time, the locking rod 41 is in a disengaged state, and the sliding member 6 is affected by the rebound force of the elastic member 2 to bounce the sliding member 6 back to its original position, and stops when the sliding member 6 abuts against the stop block 3. At this time, the protective slider 64 is abutted by the abutting force of the stop block 3 and the second clamping edge 6213 of the clamping rotating block 621, so that the second contact part 62 pops out and resets, and the pocket door body 7 itself continues to pop out due to inertia, realizing the pop-up effect of the pocket door body 7.

[0050] In this embodiment, the elastic member 2 is a return spring. In other embodiments, the specific structure of the locking member 5 is not limited, as long as it can achieve the locking and sliding states.

[0051] The present application also relates to a pocket door, comprising a pocket door body 7, a pocket door track and a rebounder with damping, characterized in that the rebounder shell 1 is assembled on the upper or lower edge of the pocket door body 7, and a toggle block 8 is provided in the pocket door track for abutting against the first contact portion 61 or the second contact portion 62 protruding from the rebounder shell 1; or, the rebounder shell 1 is assembled in the pocket door track, and the side wall of the pocket door body 7 is provided with a toggle block 8 for abutting against the first contact portion 61 or the second contact portion 62 protruding from the rebounder shell 1, and when the pocket door body 7 is hidden and closed, the toggle block of the pocket door body 7 8 drives the second contact part 62 to move synchronously, the sliding part 6 slides along the slide rail 11 toward the locking part 5, and the locking rod 41 slides to the left side of the first guide protrusion 5222. At this time, the sliding part 6 cannot continue to move forward, so the locking turn block 621 of the second contact part 62 automatically retracts. At this time, the locking rod 41 is affected by the rebound force of the elastic part 2 and enters the locking position 5233 to lock. In the process of the toggle block 8 sliding along the sliding space 13, the damper on the pocket door body 7 decelerates the door body. The pocket door body 7 slides until it contacts the first contact part 61 and ends the hidden door closing action. At this time, the door is completely hidden in the wall. When the pocket door body 7 is opened and out of the hidden state, the pocket door body 7 is pressed into the wall. At this time, when the first contact part 61 drives the sliding part 6 to slide toward the locking part 5, the locking rod 41 disengages from the locking position 5233 to unlock the door. The sliding part 6 is reset by the rebound force of the elastic part 2 and abuts against the stop block 3. The pocket door body 7 is popped out by the rebound force of the reset spring, and the second contact part 62 is reset and switched to the extended state to prepare for the next door closing.

[0052] In summary, the rebounder and pocket door for a damping door provided in the present application have the following technical effects: the rebounder shell 1 has a first contact portion 61 and a second contact portion 62 arranged at intervals. When the second contact portion 62 abuts against the toggle block 8, it can drive the sliding member 6 and the clutch structure to achieve a locking effect. The toggle block 8 can continue to decelerate and slide along the sliding space 13, and can cause the second contact portion 62 with a retraction function to retract, thereby driving the pocket door body 7 to hide into the wall. At this time, the toggle block 8 abuts against the first contact portion 61, which can realize the separate execution of the rebounder and the damper, avoiding mutual interference between the two, and the rebounder shell 1 itself is relatively long, so the interval between the first contact portion 61 and the second contact portion 62 can provide the damper with a deceleration sliding space for the door body, and will not increase the depth of the door body groove.

[0053] The technical means disclosed in the present application are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present application, and such improvements and modifications are also considered to be within the scope of protection of the present application.
