Description

Field of the invention

[0001] The present application relates to the field of hardware accessories, in particular to a rebounder for automatic soft closing of a door leaf and a cabinet door structure.

Background of the invention

[0002] A rebounder is a kind of switch applied to a cabinet, drawer, and other furniture. After installing the rebounder on the cabinet door, there is no need to apply a handle when opening and closing the cabinet door. The door is opened and closed simply by pressing on the door panel.

[0003] A conventional rebounder on the market only provides a pop-out function. When the door leaf is pressed and contacts the rebounder, the rebounder is released due to the internal elastic force, and the adjusting rod on the rebounder pops out and pushes the door leaf to open to a certain distance, so as to achieve the opening of the door leaf. When the door is to be closed, the door leaf closes and stops at the adjusting rod of the rebounder. The door leaf is still open for a certain distance and is not closed, so the door leaf requires to be pressed again so that the hook inside the rebounder is locked to close the door. The entire process of closing the door requires waiting and applying pressure again to complete the process, which is a passive and cumbersome action.

[0004] In view of the above problems, it is a technical problem to be solved urgently by those skilled in the art to develop a rebounder that simplifies the closing action of the door.

Summary of the invention

[0005] In order to overcome the defects of the prior art mentioned above, provided in the present application is a rebounder for automatic soft closing of a door leaf and a cabinet door structure. During the entire closing process, only the closing of the door requires a human external force to close the door, and there is no need to press the door again to close the door as in the case of the conventional rebounder, thus simplifying the action of closing the door.

[0006] The technical solutions adopted by the present application to solve the problems are:

[0007] A rebounder for automatic soft closing of a door leaf includes:

a housing;

an interior supporting frame, slidably provided in the housing, extendable out of the housing, the interior supporting frame being slidably provided with an adjusting rod thereon that is extendable out of the housing and is used to abut the door leaf, the adjusting rod being relatively fixed to the interior supporting frame by a snap-fit structure;

a supporting member, provided in the housing and provided with a supporting force for the interior supporting frame,

in which the adjusting rod slides backward relative to the interior supporting frame and they are relatively fixed by the snap-fit structure under a combined action of a door leaf closing force and the supporting force provided by the supporting member, so as to achieve the automatic closing of the door leaf when closing the door leaf.

[0008] Therefore, when closing the door leaf, the door leaf is firstly in contact with the adjusting rod and drives the adjusting rod backward relative to the interior supporting frame under the door leaf closing force. During the process, the interior supporting frame does not move or moves slowly under the supporting force provided by the supporting member. Until the adjusting rod and the interior supporting frame are relatively fixed to each other by the snap-fit structure, automatic closing of the door leaf is achieved.

[0009] By providing the supporting member in the rebounder of the present application, during the entire closing process, only the closing of the door requires a human external force to close the door. The door is subsequently closed automatically by the door leaf closing force. There is no need to press the door again to close the door as in the case of the conventional rebounder, thus simplifying the action of closing the door.

[0010] Further, the supporting member is a damper; the damper includes a cylinder and a piston rod that is movable and extendable in the cylinder; and any one of the cylinder and the piston rod is connected to the interior supporting frame to provide the supporting force.

[0011] Specifically, the damper is a damping oil cylinder.

[0012] Further, the interior supporting frame slides backward relative to the housing under an action of the door leaf closing force after the adjusting rod and the interior supporting frame are relatively fixed by the snap-fit structure, thereby compressing the cylinder or the piston rod until the door leaf is fully soft closed.

[0013] Therefore, the interior supporting frame slowly slides backward relative to the housing under the action of the door leaf closing force after the adjusting rod and the interior supporting frame are relatively fixed by the snap-fit structure in which the rebounder is in an inelastic state, thereby compressing the cylinder or the piston rod until the door leaf is fully soft closed. Therefore, by providing the damper, the rebounder is provided with a cushioning function, which not only increases the service life of the door leaf but also eliminates the necessity of an expensive cushioning hinge, thereby improving the functions of the door leaf and also reducing the cost of door accessories.

[0014] Further, an end of the adjusting rod is used to abut the door leaf, and an opposite end thereof is connected with a pressing block;
the snap-fit structure includes a slot opening provided on the interior supporting frame, and a hook provided on the pressing block and snap-fitted with the slot opening; or the snap-fit structure includes a hook provided on the interior supporting frame, and a slot opening provided on the pressing block and snap-fitted with the hook.

[0015] Therefore, when closing the door leaf, the adjusting rod may be fixed relative to the interior supporting frame by sliding the adjusting rod backward relative to the interior supporting frame until the hook is snap-fitted into the slot opening.

[0016] Further, the rebounder also includes a first elastic member provided on the interior supporting frame; an end of the first elastic member abuts an interior wall of the interior supporting frame; an opposite end thereof abuts the pressing block; and
when the door leaf is in a closed state, by pressing on the door leaf to disengage the hook in the snap-fit structure from the slot opening, the first elastic member releases elastic force and drives the pressing block and the adjusting rod to slide forward relative to the interior supporting frame to achieve the opening of the door leaf.

[0017] Therefore, when closing the door leaf, the adjusting rod may slide backward relative to the interior supporting frame and drive the pressing block on the adjusting rod to press the first elastic member until the hook is snap-fitted with the slot opening. When the door leaf is in a closed state, by pressing on the door leaf to disengage the hook from the slot opening, the first elastic member releases elastic force and drives the adjusting rod to reset so that the door leaf is pushed out to achieve the opening of the door leaf.

[0018] Further, the rebounder also includes a linkage mechanism provided on the interior supporting frame; and when the first elastic member releases elastic force and drives the pressing block and the adjusting rod to move forward, the linkage mechanism drives the interior supporting frame to slide forward relative to the housing.

[0019] Further, the linkage mechanism includes a transmission mechanism on the interior supporting frame, an extendable member and a second elastic member, in which:

the extendable member is slidably provided on the interior supporting frame and is partially extended out of the interior supporting frame; the second elastic member is sleeved on a part of the extendable member extended out of the interior supporting frame; an end of the second elastic member abuts the extendable member; an opposite end thereof abuts an exterior wall of the interior supporting frame; and

when the first elastic member releases elastic force and drives the pressing block and the adjusting rod to slide forward, the transmission mechanism drives the extendable member to slide and enables the second elastic member to release elastic force to drive the interior supporting frame to slide forward relative to the housing.

[0020] Therefore, when closing the door leaf, the adjusting rod may slide backward relative to the interior supporting frame, and the transmission mechanism drives the extendable member to move and press the second elastic member. When the door leaf is fully closed, by pressing on the door leaf to disengage the hook from the slot opening, the first elastic member releases elastic force and drives the pressing block and the adjusting rod to extend and reset, so that the transmission mechanism drives the extendable member to reset. At the same time, the second elastic member releases elastic force and drives the interior supporting frame forward relative to the housing, thereby pushing the cylinder or piston rod on the damper to extend and reset.

[0021] Further, the transmission mechanism includes a first rack, a gear, and a second rack that are sequentially engaged with each other; the first rack is provided on the pressing block; and the second rack is provided on the extendable member.

[0022] Further, the housing includes an upper housing and a lower housing; the upper housing and the lower housing are connected with each other to form a mounting chamber therein; the interior supporting frame and the supporting member are all provided on the mounting chamber;

the upper housing and the lower housing are all provided with a through-hole for extending the interior supporting frame and the adjusting rod; and

the upper housing and the lower housing are all provided with a mounting hole for mounting on a cabinet body.

[0023] Further, a decorative cover for covering the upper housing or the lower housing, and the decorative cover is provided with escaping holes for extending the interior supporting frame and the adjusting rod on both a front side and a rear side thereof.

[0024] Additionally, provided in a second aspect of the present application is a cabinet door structure, including a cabinet body, a door leaf hinged to the cabinet body and a rebounder mentioned above mounted on the cabinet body.

[0025] In summary, the rebounder for automatic soft closing of a door leaf and the cabinet door structure of the present application provides the following beneficial effects:

(1) By adopting the rebounder and the cabinet door structure of the present application, during the entire closing process, only the closing of the door requires a human external force to close the door, and there is no need to press the door again to close the door as in the case of the conventional rebounder, thus simplifying the action of closing the door.

(2) The rebounder and the cabinet door structure of the present application, since the rebounder is provided with a cushioning function, not only increases the service life of the door leaf, but also eliminates the necessity of an expensive cushioning hinge, thereby improving the functions of the door leaf and also reducing the cost of door accessories.

Detailed description of the preferred embodiments

[0028] For a better understanding and implementation, the technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with the attached drawings of the present application.

[0029] In the description of the present application, it is to be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and other orientation or position relationships are based on the orientation or position relationships shown in the attached drawings. It is only intended to facilitate description and simplify operation, but not to indicate or imply that the referred device or element has a specific orientation, or is constructed and operated in a specific orientation. Therefore, they should not be construed as a limitation of the present application.

[0030] Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are used only to describe specific embodiments and are not intended as a limitation of the application.

[0031] Referring to Fig. 1 to Fig. 13, provided firstly in the present application is a rebounder 1 for automatic soft closing of a door leaf, the rebounder being used to be mounted on such as a top plate and a side plate of a cabinet body. The rebounder 1 only requires a human external force to close the door. The door is subsequently closed automatically by the door leaf closing force. There is no need to press the door again to close the door as in the case of the conventional rebounder, thus simplifying the action of closing the door.

[0032] Referring to Fig. 1, the rebounder 1 includes a housing and an interior supporting frame 13 provided in the housing. The housing is rectangular in shape and includes an upper housing 11 and a lower housing 12 connected with each other; the upper housing 11 and the lower housing 12 are connected with each other to form a mounting chamber therein; and the interior supporting frame 13 is slidably provided on the mounting chamber and partially extended out of the housing. The interior supporting frame 13 is slidably provided with an adjusting rod 14 thereon that is extendable out of the housing and is used to abut the door leaf, the adjusting rod 14 being relatively fixed to the interior supporting frame 13 by a snap-fit structure. Additionally, the rebounder 1 also includes a supporting member provided in the mounting chamber and provided with a supporting force for the interior supporting frame 13. The adjusting rod 14 slides backward relative to the interior supporting frame 13 and they are relatively fixed by the snap-fit structure under a combined action of a door leaf closing force and the supporting force provided by the supporting member, so as to achieve the automatic closing of the door leaf when closing the door leaf.

[0033] Therefore, when closing the door leaf, the door leaf is firstly in contact with the adjusting rod 14 and drives the adjusting rod backward relative to the interior supporting frame 13 under the door leaf closing force. During the process, the interior supporting frame 13 does not move or moves slowly under the supporting force provided by the supporting member. Until the adjusting rod 14 and the interior supporting frame 13 are relatively fixed to each other by the snap-fit structure, automatic closing of the door leaf is achieved.

[0034] By providing the supporting member in the rebounder 1 of the present application, during the entire closing process, only the closing of the door requires a human external force to close the door. The door is subsequently closed automatically by the door leaf closing force. There is no need to press the door again to close the door as in the case of the conventional rebounder, thus simplifying the action of closing the door.

[0035] In the present embodiment, the upper housing is provided with a plurality of studs 111, and the lower housing 12 is provided with a plurality of second mounting holes 121 corresponding to the plurality of studs 111. Therefore, the fixed connection between the upper housing 11 and the lower housing 12 is achieved by applying a screw through the second mounting hole 121 and being threaded to the stud 111. Additionally, ends of the upper housing 11 and the lower housing 12 are all provided with a through-hole 114 for extending the interior supporting frame 13 and the adjusting rod 14.

[0036] Furthermore, the upper housing 11 and the lower housing 12 are correspondingly provided with a plurality of first mounting holes 112 and third mounting holes 122, in which the first mounting hole 112 is in communication with the third mounting hole 122 to form a through-hole. Therefore, when the upper housing 11 or the lower housing 12 is required to be fixed on the cabinet door, securing the rebounder 1 to the cabinet door is achieved simply by applying a screw passing through the through-hole and threading it onto the cabinet door.

[0037] Referring to Fig. 1, the rebounder 1 also includes a decorative cover 10 for covering the upper housing 11 or the lower housing 12, and the decorative cover 10 is provided with escaping holes 101 for extending the interior supporting frame 13 and the adjusting rod 14 on both a front side and a rear side thereof. Additionally, two lateral exterior walls of the upper housing 11 are provided with a first snap-fit slot 113, and two lateral exterior walls of the lower housing 12 are provided with a second snap-fit slot 123. The first snap-fit slot 113 and the second snap-fit slot 123 are identical in structure. Two lateral interior walls of the decorative cover 10 are provided with a buckle 102 for snap-fitting with the first snap-fit slot 113 or the second snap-fit slot 123. Therefore, when the decorative cover 10 is covered on the upper housing 11 or the lower housing 12 until the buckle 102 is snap-fitted with the first snap-fit slot 113 or the second snap-fit slot 123, it is achieved that the decorative cover 10 is fixed on the housing.

[0038] Referring to Fig. 2, the interior supporting frame 13 is substantially H-shaped, which includes a first vertical part 131, a second vertical part 132 and a horizontal part 133 connected to the first vertical part 131 and the second vertical part 132 respectively. The adjusting rod 14 is slidably provided in the front end of the first vertical part 131 of the interior supporting frame 13. The front end of the adjusting rod 14 is used to abut the door leaf, and the rear end of the adjusting rod 14 is connected to a pressing block 141 with a strip shape. The rear end of the first vertical part 131 of the interior supporting frame 13 is horizontally provided with a fixing column 1311, in which a first elastic member 16 is sleeved on the fixing column 1311. An end of the first elastic member 16 abuts an interior wall of the interior supporting frame 13, and an opposite end thereof abuts the pressing block 141. The pressing block 141 is provided with an escaping slot for avoiding the fixing column 1311.

[0039] In the present embodiment, the first elastic member 16 is an elastic compression spring.

[0040] Referring to Fig. 1 to Fig. 3, the snap-fit structure includes a slot opening 13131 on the interior supporting frame 13 and a hook 1411 provided on the pressing block 141 and snap-fitted with the slot opening 13131. Specifically, a middle part of the first vertical part 131 of the interior supporting frame 13 is provided with a guiding slot 1314. The guiding slot 1314 is provided with a protrusion 1313 and a wedge-shaped block 1315. A side wall of the protrusion 1313 is provided with a gap to form the slot opening 13131. A side wall of the wedge-shaped block 1314 is provided with a guiding slant.

[0041] Therefore, when closing the door leaf, the door leaf drives the adjusting rod 14 and the pressing block 141 to overcome the elastic force of the first elastic member 16 to slide backward relative to the interior supporting frame 13, which further drives the hook 1411 on the pressing block 141 to slide along the guiding slot 1314 until the hook 1411 is snap-fitted with the slot opening 13131 on the protrusion 1313. Then, the first elastic member 16 is compressed and the adjusting rod 14 is fixed and retracted. That is to say, the door leaf is closed. When the door leaf is fully closed, by pressing the door leaf again, the door leaf may drive the adjusting rod 14 to slide backward again. Then, the hook 1411 moves along the guiding slant of the wedge-shaped block 1315 to disengage from the slot opening 13131. The first elastic member 16 releases the elastic force to drive the adjusting rod 14 to slide along the guiding slot 1314 and gradually move forward until it is fully reset. Then, the adjusting rod 14 is extended. That is to say, the door leaf is opened.

[0042] In the present embodiment, the snap-fit structure also includes a first pressing plate 1412, and the first pressing plate 1412 is fixed on the pressing plate 141 by screws and presses the hook 1411, so as to prevent the hook from disengaging from the pressing plate 141 during the moving process.

[0043] Admittedly, in other embodiments, the provision positions of the snap-fit structure may be switched, i.e., the slot opening 13131 is provided on the pressing block 141 and the hook 1411 is provided on the interior supporting frame 13, which may also achieve the same technical effect, which is not limited hereby.

[0044] Referring to Fig. 1, the supporting member is a damper 15. The damper 15 includes a cylinder 151 and a piston rod 152 that is movable and extendable in the cylinder 151. A side wall of the first vertical part 131 of the interior supporting frame 13 is provided with a protruding block 1312, in which a front part of the piston rod 152 is connected to the protruding block 1312 to provide supporting force.

[0045] In the present embodiment, the damper 15 is a damping oil cylinder. Admittedly, in other embodiments, the damper 15 may also be a damping air cylinder or other supporting member with a cushioning function, which is not limited hereby.

[0046] Therefore, the interior supporting frame 13 slowly slides backward relative to the housing under an action of the door leaf closing force after the adjusting rod 14 and the interior supporting frame 13 are relatively fixed by the snap-fit structure in which the rebounder 1 is in an inelastic state, thereby compressing the piston rod 152 until the door leaf is fully soft closed. Therefore, by providing the damper 15, the rebounder 1 is provided with a cushioning function, which not only increases the service life of the door leaf, but also eliminates the necessity of an expensive cushioning hinge, thereby improving the functions of the door leaf and also reducing the cost of door accessories.

[0047] Admittedly, in other embodiments, the damper 15 may also be mounted reversely. The cylinder 151 on the damper 15 is connected to the interior supporting frame 13, and the interior supporting frame 13 moves and drives the cylinder 151 to extend and move relative to the piston rod 152, which may also achieve the same effect of cushioning, which is not limited hereby.

[0048] Referring to Fig. 1, the rebounder 1 also includes a linkage mechanism provided on the interior supporting frame 13; and when the first elastic member 16 releases elastic force and drives the pressing block 141 and the adjusting rod 14 to move forward, the linkage mechanism drives the interior supporting frame 13 to slide forward relative to the housing. Specifically, the linkage mechanism includes a transmission mechanism 19, an extendable member 17 and a second elastic member 18, the extendable member 17 is slidably provided on a second vertical part 132 of the interior supporting frame 13 and a rear part thereof is extended out of the interior supporting frame 13; the second elastic member 18 is sleeved on a part of the extendable member 17 extended out of the interior supporting frame 13; an end of the second elastic member 18 abuts the extendable member 17; an opposite end thereof abuts an exterior wall of the interior supporting frame 13. The transmission mechanism 19 includes a first rack 191, a gear 192, and a second rack 193 that are sequentially engaged with each other; the first rack 191 is provided on the pressing block 141; the gear 192 is provided on the horizontal part 133 of the interior supporting frame 13; and the second rack 193 is provided on the extendable member 17.

[0049] In the present embodiment, the second elastic member 18 is an elastic compression spring; the extendable member 17 is an extendable rod, and is integrally formed with the second rack 193; and the pressing block 141 and the first rack 191 are formed integrally.

[0050] Admittedly, in other embodiments, the transmission mechanism may be such as a belt-pulley transmission mechanism, which is not limited hereby.

[0051] Therefore, when closing the door leaf, the door leaf drives the adjusting rod 14 to slide backward relative to the interior supporting frame 13, and the transmission mechanism 19 drives the extendable member 17 to move and press the second elastic member 18. When the door leaf is fully closed, by pressing on the door leaf to disengage the hook 1411 from the slot opening 13131, the adjusting rod 14 and the pressing block 141 are reset under the elastic force of the first elastic member 16 and drives the extendable member 17 by the transmission mechanism 19 to extend and reset. Then, the second elastic member 18 releases the elastic force to push the interior supporting frame 13 to move forward relative to the housing, so as to push the piston rod 152 on the damper 15 to extend and reset.

[0052] Additionally, the transmission mechanism 19 also includes a second pressing plate 194. The pressing plate 194 is fixed on the gear 192 by screws and presses the gear 192, so as to prevent the gear 192 from shifting during the engaging transmission.

[0053] Referring to Fig. 5 to Fig. 13, the working process of the rebounder of the present application is as follows:

[0054] When closing the door leaf, the door leaf is firstly in contact with the adjusting rod 14 during the closing process and drives the adjusting rod 14 to slide backward under the door leaf closing force. During the process, the interior supporting frame 13 does not move or moves slowly under the action of the damper 15 so that the adjusting rod 14 drives the pressing block 141 to move together and presses the first elastic member 16. When the hook 1411 on the pressing block 141 moves along the guiding slot 1314, the first rack 191 on the pressing block 141 drives the second rack 193 and the extendable member 17 by the gear 192 and presses the second elastic member 18, until the hook 1411 on the pressing block 141 is hooked into the slot opening 13131 and the adjusting rod 14 is locked. Therefore, the automatic closing of the door leaf is achieved. During the process, the interior supporting frame 13 temporarily does not slide into place under the action of the damping oil cylinder. After the above locking action, the first elastic member 16 and the second elastic member 18 are both compressed and locked, the interior supporting frame 13 is in an inelastic state with the housing. The interior supporting frame 13 slides backward relative to the housing under the action of the door leaf closing force and slowly presses the piston rod 152 of the damper 15 until the door leaf is fully closed with cushioning, thereby achieving the effect of the cushioning.

[0055] When the door leaf is fully closed, by pressing the door leaf, the door leaf is in contact with the adjusting rod 14 and drives the hook 1411 on the pressing block 141 to overcome the elastic force of the first elastic member 16 to move backward. The hook 1411 is then disengaged from the restriction of the slot opening 13131 so as to release the elastic force of the first elastic member 16. The adjusting rod 14 is extended out to reset when the first elastic member 16 releases the elastic force so as to achieve the opening of the door leaf. While the adjusting rod 14 and the pressing block 141 pop out, the transmission mechanism 19 drives the extendable member 17 to slide and reset, which synchronously releases the elastic force of the second elastic member 18. The elastic force enables the interior supporting frame 13 to move forward relative to the housing, so as to pull the piston rod 152 on the damper 15 to reset until the rebounder 1 is restored to the initial state.

[0056] Additionally, provided in a second aspect of the present application is a cabinet door structure, including a cabinet body, a door leaf hinged to the cabinet body and a rebounder 1 mentioned above mounted on the cabinet body.

[0057] In summary, the rebounder 1 for automatic soft closing of a door leaf and the cabinet door structure of the present application provide the following beneficial effects:

(1) By adopting the rebounder 1 and the cabinet door structure of the present application, during the entire closing process, only the closing of the door requires a human external force to close the door, and there is no need to press the door again to close the door as in the case of the conventional rebounder, thus simplifying the action of closing the door.

(2) The rebounder 1 and the cabinet door structure of the present application, since the rebounder 1 is provided with a cushioning function, not only increases the service life of the door leaf, but also eliminates the necessity of an expensive cushioning hinge, thereby improving the functions of the door leaf and also reducing the cost of door accessories.
