Description

Rebounder Technical Field

[0001] The present application relates to the technical field of rebounders, and in particular to a rebounder. Background Art

[0002] A rebounder is a furniture hardware accessory used in place of handles to open and close cabinet doors. Unlike handles, which are mounted on the cabinet's surface, rebounders are attached to the cabinet's side panels, creating a more aesthetically pleasing and simple finish. When the door is closed, the rebounder locks the panel by attracting an iron block and a magnet. Pressing the door causes the elastic mechanism inside the rebounder to push the telescopic element out, which then springs the door open, allowing it to open.

[0003] However, the rebounder is difficult to adjust after installation and has a limited adjustment range, making it difficult to meet the adjustment needs of larger door gaps.

[0059] In order to make the objectives, technical solutions, and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and examples. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. This application will be described in detail below with reference to the accompanying drawings and in conjunction with the examples.

[0060] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0061] The following provides an explanation of the terms used in this application.

[0062] Rebounder: A spring-loaded device used to control the opening and closing of furniture such as doors, cabinets, or covers. Rebounders can be installed on the side panels of cabinets to improve the aesthetics and convenience of furniture.

[0063] To facilitate those skilled in the art to understand the technical solutions provided in the embodiments of the present application, the following describes the relevant technologies:

[0064] A rebounder is a common furniture hardware component. It's used in place of handles to open and close cabinet doors. Unlike handles, which are mounted on the cabinet's surface, rebounders are attached to the cabinet's side panels, creating a more aesthetically pleasing and simple finish. When the door is closed, the rebounder locks the door in place by attracting an iron block and a magnet. Pressing the door causes the elastic mechanism inside the rebounder to push the telescopic element out, which then springs the door open, allowing it to open.

[0065] However, the rebounder known to the present applicant is difficult to adjust after installation and has a limited adjustment range, which makes it difficult to meet the adjustment requirements of larger door gaps.

[0066] To this end, embodiments of the present application provide a rebounder. This rebounder can bidirectionally adjust the relative position of the core and mounting base, thereby adjusting the relative distance between the locking member and the locking base. This allows for simple and quick adjustment of the door gap, with a wide adjustment range. See below for details.

[0067] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0068] As shown in Figures 1 to 13, the rebounder can include a locking member 1. The locking member 1 can be secured to a locking base 2 mounted on a door panel using a snap-fit ​​mechanism, thereby locking the door panel. The locking member 1 can be adjusted relative to the locking base 2 via a screw-fit mechanism, thereby adjusting the door gap.

[0069] The respective structures and matching relationship of the locking member 1 and the locking base 2 will be described below.

[0070] The locking member 1 can be installed on the side panel.

[0071] The locking base 2 can be installed at a corresponding position on the inner side of the door panel.

[0072] The locking member 1 may include a core, a mounting base 11, and an adjusting nut 18. A retractable claw 131 is provided at the end of the core near the locking base 2. The claw 131 is used to clamp the locking base 2 located on the door panel, allowing the locking member 1 to lock the locking base 2, thereby locking the door panel. The core is slidably mounted on the mounting base 11. The end of the core away from the locking base 2 is a threaded end 163. Accordingly, the end of the mounting base 11 away from the locking base 2 extends to form a convex wall. The convex wall is provided with a first through-hole 1141, through which the adjusting nut 18 can be threadedly engaged with the threaded end 163. Under the action of a first external force, the adjusting nut 18 can rotate in a first clockwise direction. The threaded structure converts the rotational motion into axial motion, and the threaded end 163 gradually moves away from the adjusting nut 18, thereby driving the core to slide away from the convex wall at the rear of the mounting base 11. Under the action of a second external force, the adjusting nut 18 can rotate in a second clockwise direction. The threaded structure converts the rotational motion into axial motion, and the threaded end 163 gradually approaches the adjusting nut 18, thereby driving the core body to slide closer to the protruding wall at the rear of the mounting base 11. It can be seen that in this embodiment, rotating the adjusting nut 18 can bidirectionally adjust the relative position of the core body and the mounting base 11, thereby adjusting the relative distance between the locking member 1 and the locking base 2, expanding the door gap adjustment range (-2 mm to +7 mm). It can be seen that the rebounder of the embodiment of the present application can easily and quickly adjust the door gap and has a large door gap adjustment range.

[0073] In an optional embodiment, as shown in FIG4 , the adjusting nut 18 includes a connected nut 181 and a screw 182. The nut 181 can be selected as needed, such as a toothed nut or a hexagonal nut, to further reduce the difficulty of adjustment. The screw 182 has a first circumferential groove 1821 and an internal thread 1822. The locking member 1 also includes a retaining spring 19.

[0074] The internal thread 1822 is screwed into the threaded end 163 , and the retaining spring 19 is detachably engaged with the first circumferential groove 1821 and abuts against the convex wall.

[0075] In this embodiment, the retaining spring 19 and the convex wall abut against each other, thereby fixing the adjusting nut 18 and effectively limiting its axial movement, thereby further improving the structural stability and reliability of the rebounder.

[0076] In some embodiments, the end of the mounting base 11 away from the locking base 2 may further extend to form an arcuate protrusion 114. The arcuate protrusion 114 comprises a connected arcuate surface and a convex wall. The adjusting nut 18 extends through the convex wall into the arcuate protrusion 114. Covered by the arcuate surface, the service life of the adjusting nut 18 can be effectively extended.

[0077] In an optional embodiment, as shown in Figures 1 to 3, the locking member 1 may further include a core barrel 12 for accommodating the core body. Wing-shaped protrusions 123 may be provided on either side of the core barrel 12, and a bottom plate 124 may be provided at the bottom of the core barrel 12. The gap between the wing-shaped protrusions 123 and the bottom plate 124 may form a first guide groove 125.

[0078] As shown in Figure x, the mounting base 11 is provided with a guide protrusion 111, which is located on the inner walls of two opposite side panels of the mounting base 11. The guide protrusion 111 can be set as continuous or dispersed guide protrusions 111 as needed to achieve better guiding effect or save costs.

[0079] The first guide groove 125 is adapted to the guide protrusion 111 so that the core barrel 12 can be detachably mounted on the mounting base 11 .

[0080] In this embodiment, through the cooperation between the first guide groove 125 and the guide protrusion 111, the core barrel 12 can slide in and out of the mounting base 11, thereby achieving rapid disassembly and assembly.

[0081] In an optional embodiment, as shown in Figures 1 to 3, the side of the bottom plate 124 may be provided with an opening 1241 and a hook 1242, wherein the hook 1242 is located at the opening 1241 and extends outward. The mounting base 11 may also be provided with a socket 112, wherein the socket 112 is located on two opposing side panels of the mounting base 11.

[0082] When force is applied to slide the core barrel 12 into the mounting base 11, the two opposite side panels of the mounting base 11 squeeze the hook 1242, causing the hook 1242 to be accommodated in the opening 1241. At this time, the core barrel 12 can slide smoothly into the mounting base 11. When sliding to the position where the socket 112 is located, since the hook 1242 is no longer squeezed by the side panels, the hook 1242 bounces out from the opening 1241 and engages with the socket 112, thereby quickly fixing the core barrel 12 in the mounting base 11. Correspondingly, the core barrel 12 can also be removed from the mounting base 11. Under the action of external force, the two opposite side panels of the mounting base 11 squeeze the hook 1242 again, causing the hook 1242 to be accommodated in the opening 1241 again, allowing the core barrel 12 to slide smoothly out of the mounting base 11.

[0083] In this embodiment, the opening 1241, the hook 1242 and the insertion hole 112 cooperate with each other to achieve quick disassembly and fixation, thereby improving installation efficiency.

[0084] In an optional embodiment, as shown in Figures 1 to 3, the mounting base 11 may further include a second guide groove 113, which is provided at an end of the mounting base 11 away from the locking base 2. The locking member 1 may further include a first cover plate 20, which includes a curved surface and a guide plate 201, wherein the guide plate 201 is formed by extending inward from both ends of the curved surface.

[0085] The second guide groove 113 is adapted to the guide plate 201 so that the first cover plate 20 can be detachably mounted on the mounting base 11 .

[0086] In this embodiment, the first cover plate 20 can be slid into and out of the second guide slot 113 via the guide plate 201, enabling quick assembly and disassembly. By removing the first cover plate 20, the engagement between the threaded end 163 and the adjustment nut 18 can be quickly and accurately determined, allowing for better adjustment of the relative position of the core and mounting base 11. The second guide slot 113 can be adjusted to a desired length. By sliding the first cover plate 20 within the second guide slot 113, the first cover plate 20 can be maintained above the threaded end 163 and the adjustment nut 18, further protecting the components.

[0087] The structure and matching relationship of the locking member 1 will be further described below with reference to more drawings.

[0088] In an optional embodiment, as shown in Figures 1 to 5, the mounting base 11 further has a first assembly hole 115 and a second assembly hole 116 for screws to pass through. The first assembly hole 115 and the second assembly hole 116 are provided on the bottom plate of the mounting base 11 or on mounting wings 117 on both sides of the mounting base 11.

[0089] In this embodiment, the mounting base 11 can be mounted on the side panel in two ways: open mounting and concealed mounting. Concealed mounting is invisible, more aesthetically pleasing, and has good damage resistance. Open mounting is visible and more convenient to disassemble.

[0090] In some embodiments, as shown in Figures 1 to 8, the core body may further include a sliding portion, wherein the sliding portion includes a clamping portion 13 facing the locking base 2, and the clamping portion 13 is provided with the claw 131. The interior of the core barrel 12 may form a slide rail for the sliding portion to slide axially, thereby adjusting the degree of opening and closing of the claw 131.

[0091] In this embodiment, the sliding portion can slide axially into and out of the core barrel 12. When sliding into the core barrel 12, the claws 131 contract under the constraints of the inner wall of the core barrel 12. When sliding out of the core barrel 12, the claws 131 expand. The degree of opening and closing of the claws 131 can be effectively adjusted through the core barrel 12, thereby locking and releasing the locking base 2.

[0092] In some embodiments, the end of the sliding portion facing the locking base 2 may be further provided with two opposite through holes for allowing the two claws of the claw 131 to extend.

[0093] The following will introduce the structure of the sliding part and the matching relationship of the components.

[0094] In an optional embodiment, as shown in FIG. 7 , the sliding portion may include a first fixing portion 14 and a second fixing portion 15 .

[0095] One end of the first fixing portion 14 can extend out of the core barrel 12, and the other end is located in the core barrel 12. The second fixing portion 13 is located in the core barrel 12. The first ends of the first fixing portion 14 and the second fixing portion 15 are screwed together and their axial relative positions are adjustable.

[0096] In this embodiment, a first screw thread 141 may be provided on the inner side wall of the first fixing portion 14. Correspondingly, a second screw thread 151 may be provided on the outer side wall of the first end of the second fixing portion 15, wherein the first end of the second fixing portion 15 is the end of the second fixing portion 15 that is closer to the first fixing portion 14. The first screw thread 141 and the second screw thread 151 can be screwed together, connecting the first fixing portion 14 and the second fixing portion 15 together, and the relative position of the two can be adjusted by rotation. In actual application, the relative position of the first fixing portion 14 and the second fixing portion 15 can be adjusted by rotating the first fixing portion 14 in a predetermined clockwise direction, thereby precisely adjusting the door gap.

[0097] In this embodiment, the screw structure can provide a door gap adjustment range of ±2 mm. It should be noted that the screw structure can also be appropriately adjusted according to actual needs to provide different door gap adjustment ranges.

[0098] In the above embodiment, the first fixing portion 14 and the second fixing portion 15 are connected by a screw structure to achieve precise adjustment of the door gap. The following will provide an embodiment to illustrate how the holding portion 13 and the first fixing portion 14 are connected.

[0099] In some embodiments, the first fixing portion 14 may further be provided with a limiting block, which is located on the inner wall of the first fixing portion 14 . There may be two limiting blocks, which are positioned opposite to each other.

[0100] Correspondingly, as shown in Figures 6-8, the clamping portion 13 may also be provided with at least two opposing, spaced-apart fixing claws 132. The fixing claws 132 are located at the end of the clamping portion facing away from the locking base 2. An inclined portion 1321 is provided on the outer side of the free end of the fixing claws 132, forming a recessed snap 1322 between the inclined portion 1321 and the clamping claws 131. The inclined portion 1321 is used to adjust the gap between the two fixing claws 132 so that the fixing claws 132 extend into the first fixing portion 14. The recessed snap 1322 is used to engage with the stop block for securement.

[0101] In this embodiment, the two fixing claws 132 of the holding portion 13 extend into the first fixing portion 14 until they are blocked by the limit block. At this time, the inclined portions 1321 of the two fixing claws 132 are against the limit block. Under the action of external force, the inclined portion 1321 will decompose the external force into a force in the vertical direction. The force in the vertical direction can squeeze the inclined portion 1321, thereby reducing the gap between the two fixing claws 132, so that the holding portion 13 can continue to extend into the first fixing portion 14. Finally: the concave bayonet 1322 and the shape of the limit block are adapted to fit together, so that the holding portion 13 and the first fixing portion 14 are engaged and connected. In this embodiment, there is no need to fix the holding portion 13 and the first fixing portion 14 with pins, which is simple to operate and effectively reduces costs.

[0102] In some embodiments, the stopper may have an inclined surface that cooperates with the inclined portion 1321 to more conveniently adjust the gap between the two fixing claws 132, thereby reducing operational difficulty. In some embodiments, the clamping portion 13 may be made of plastic, allowing the clamping portion 13 to automatically deform and recover due to the plastic's elasticity. It should be noted that the clamping portion 13 may also be made of other materials and connected to the first fixing portion 14 in other ways, depending on actual needs, and will not be elaborated here.

[0103] The above embodiment introduces the structure of the sliding portion and the matching relationship between the components. The structure and matching relationship of the other components of the rebounder will be introduced below.

[0104] In an optional embodiment, as shown in Figures 9-10, the second fixing portion 15 may also be provided with a semi-cylindrical arc surface 152 and a first flange 153. The semi-cylindrical arc surface 152 is formed by extending from the second end of the second fixing portion 15. The first flange 153 is located at the bottom of the semi-cylindrical arc surface 152. The core body may also include a hook portion 16 and a spring 17. Among them, the hook portion 16 may be provided with a hook 161 and a hook fixing seat 162. The hook 161 is fixed on the hook fixing seat 162. The hook fixing seat 162 is fixed on the end of the core tube 12 away from the locking base 2. The spring 17 is supported between the hook fixing seat 162 and the first flange 153.

[0105] Among them, the inner wall of the semi-cylindrical arc surface 152 is also provided with a Y-shaped boss 1521, a hook introduction part and a hook exit part. The hook introduction part is used to guide the hook 161 to fall into the middle fork of the Y-shaped boss 1521, and the hook exit part is used to guide the hook 161 to detach from the Y-shaped boss 1521.

[0106] In this embodiment, under the action of the thrust, when the sliding portion compresses the spring 17 and slides to the first position, the hook 161 falls into the middle fork of the Y-shaped boss 1521 under the guidance of the hook introduction portion. After the thrust disappears, the hook 161 hooks the middle fork of the Y-shaped boss 1521, and the relative positions of the sliding portion and the core barrel 12 remain unchanged, thereby keeping the door panel in a tightly closed state or other desired state. At this time, the spring 17 remains in a compressed state. When the thrust is applied again, the sliding portion further compresses the spring 17 and slides to the second position, and the hook 161 disengages from the Y-shaped boss 1521 under the guidance of the hook outlet portion. When the thrust disappears again, based on the rebound force of the spring 17, the sliding portion slides out of the core barrel 12, and the claw 131 releases the locking base 2, thereby achieving the opening of the door panel.

[0107] The following is an exemplary introduction to the structure of the hook introduction part and the hook exit part and the matching relationship of the parts.

[0108] In some embodiments, as shown in Figures 9-10, the hook introduction portion may include a first passage 1522, a first inclined surface 1523 and a first U-shaped groove 1524. The first passage 1522, the first inclined surface 1523 and the first U-shaped groove 1524 are connected in sequence. The first passage 1522 is formed by the gap between the first side wall of the Y-shaped boss 1521 and the corresponding side edge of the semi-cylindrical arc surface 152, and is used for the hook 161 to slide to the first inclined surface 1523. The first inclined surface is used to guide the hook 161 to fall into the first U-shaped groove 1524. The first U-shaped groove 1524 is used to guide the hook 161 to fall into the middle fork of the Y-shaped boss.

[0109] The hook lead-out portion may include a second inclined surface 1525 . The second inclined surface 1525 is opposite to the middle fork of the Y-shaped boss 1521 and is used to guide the hook 161 to separate from the Y-shaped boss 1521 .

[0110] In this embodiment, when the sliding portion compresses the spring 17 and slides to the first position, the hook 161 sequentially passes through the first passage 1522, the first inclined surface 1523, and the first U-shaped groove 1524, and engages with the middle fork of the Y-shaped boss 1521, thereby maintaining the relative position of the sliding portion and the core barrel 12, and keeping the door panel locked. Under the action of an external force, when the sliding portion continues to compress the spring 17 and slides to the second position, the hook 161 disengages from the Y-shaped boss 1521 under the guidance of the second inclined surface 1525. When the external force disappears and the spring 17's rebound force is applied, the sliding portion slides out of the core barrel 12, and the claw 131 releases the locking base 2, thereby opening the door panel.

[0111] In some embodiments, the hook guide portion may further include a second passage 1527. Second passage 1527 is formed by the gap between the second sidewall of the Y-shaped boss 1521 and the corresponding side edge of the semi-cylindrical curved surface 152. The second sidewall is positioned opposite the first sidewall. Second passage 1527 allows hook 161 to pass through. In some embodiments, the hook guide portion may further include a second U-shaped groove 1526 connected to the second inclined surface 1525. Second U-shaped groove 1526 is used to guide hook 161 through second passage 1527 and away from the semi-cylindrical curved surface 152.

[0112] The above embodiment describes how the sliding portion, the hook portion 16 and the spring 17 cooperate to maintain the door panel closed and open. The internal structure of the hook portion 16 and the relationship between the components will be described below as an example.

[0113] In an optional embodiment, as shown in Figure 11, the hook fixing seat 162 may include a fixing plate 1621 and a circular base 1622. The fixing plate 1621 and the circular base 1622 are perpendicular to each other and fixedly connected. The hook portion 16 also includes the threaded end 163, which is formed by extending from the end of the circular base 1622 away from the locking base 2. A deformable protrusion 1627 is provided at one end of the circular base 1622 facing the locking base 2. Correspondingly, a deformable recess 121 is provided at the end of the core barrel 12 away from the locking base 2. The deformable protrusion 1627 and the deformable recess 121 cooperate to engage and fix the core barrel 12 and the circular base 1622.

[0114] In this embodiment, the hook fixing seat 162 is fixed to the end of the core barrel 12 by the cooperation between the deformed protrusion 1627 and the deformed recess 121 .

[0115] In some embodiments, hook 161 may include a hook 1611 and a hook rod 1612. Hook 1611 and hook rod 1612 are fixedly connected. Part of the sidewall of hook rod 1612 is adjacent to fixing plate 1621. Fixing plate 1621 may be provided with a first protrusion 1624 and a second protrusion 1625. First protrusion 1624 and second protrusion 1625 are respectively provided on either side of hook rod 1612, and together, first protrusion 1624 and second protrusion 1625 are used to limit the swing range of hook rod 1612.

[0116] In this embodiment, the first protrusion 1624 and the second protrusion 1625 on both sides of the hook rod 1612 are used to jointly limit the swing range of the hook rod 1612, thereby avoiding the situation where the hook 1611 hooks the spring 17 due to excessive swinging of the hook rod, causing the elastic mechanism to be stuck and fail, and further optimizing the rebounder structure to make the rebounder structure more reasonable and stable.

[0117] In an optional embodiment, as shown in FIG11 , the hook fixing seat 162 may further include a blocking portion 1623, which is formed by extending from the end of the circular base 1622 close to the fixing plate 1621. The blocking portion 1623 is located above the hook rod 1612 and is used to limit the axial movement of the hook rod 1612.

[0118] In this embodiment, a blocking portion 1623 is provided to limit the axial movement of the hook rod 1612, thereby avoiding the situation where the hook 1611 hooks the spring 17 due to the large axial movement range of the hook rod 1612, causing the elastic mechanism to be stuck and fail. The rebounder structure is further optimized, making the rebounder structure more reasonable and stable.

[0119] In an optional embodiment, as shown in Figure 11, the core barrel 12 is provided with a first pin hole 122, and the first pin hole 122 is located at the end of the core barrel 12 away from the locking base 2. The free end of the hook 161 is provided with a ring to form a circular through hole 1613. The blocking portion is provided with an arc-shaped hole 1628. A second pin hole 1626 is provided on the fixing plate. Among them, the first pin hole 122, the arc-shaped hole 1628, the circular through hole 1613 and the second pin hole 1626 are positioned correspondingly, and the pin shaft 164 passes through the first pin hole 122, the arc-shaped hole 1628, the circular through hole 1613 and the second pin hole 1626 in sequence to bridge the two sides of the core barrel 12, so that the hook portion 16 is fixedly connected to the core barrel 12.

[0120] In this embodiment, the hook portion 16 is fixed in the core tube 12 by a pin 164, thereby further improving the structural stability of the rebounder.

[0121] It should be noted that other methods can also be used to fixedly connect the hook portion 16 to the core barrel 12, which can be selected according to actual needs and is not limited here.

[0122] In actual applications, the installation position of the locking member 1 or the locking base 2 may deviate from the predetermined position, which may cause the locking base 2 to be misaligned with the locking member 1 when closing the door, thereby causing the door to fail to lock. To reduce the possibility of door locking failure, an exemplary embodiment is provided below.

[0123] In an optional embodiment, the locking base 2 may include a base body 21 and a rotating column 23 .

[0124] As shown in Figures 12-13, the base body 21 may be provided with a fixing hole 213, the inner wall of which is provided with a snap ring 2131. Correspondingly, the rotating column 23 may include a clamping end 231 and a flange end 232. The clamping end 231 is configured to removably engage with the claw 131. The flange end 232 may include a second flange 2321, a third flange 2322, and a second circumferential groove 2323 located between the second flange 2321 and the third flange 2322.

[0125] The snap ring 2131 and the second circumferential groove 2323 engage to confine the rotating column 23 to the base body 21. The diameter of the second circumferential groove 2323 is smaller than the inner diameter of the snap ring 2131, and the third flange 2322 is larger than the inner diameter of the snap ring 2131. The third flange 2322 is movably confined between the snap ring 2131 and the door panel.

[0126] In this embodiment, the rotating column 23 can rotate and swing 360 degrees circumferentially within the retaining ring 2131, allowing the rotating column 23 to fine-tune its angle to align with the latch 131, thereby reducing the possibility of door locking failure. This process does not require the use of external tools to adjust the position of the locking base 2 or the locking member 1, thereby improving the practicality and convenience of the rebound device.

[0127] In some embodiments, the base body 21 may further include a third assembly hole 211 and a fourth assembly hole 212. The third assembly hole 211 and the fourth assembly hole 212 can be threaded with screws. The installer can secure the locking base 2 to the door panel using screws. Alternatively, welding or other methods can be used to secure the locking base 2 to the door panel. This method is not limited to the above and is selected based on actual needs.

[0128] In some embodiments, the locking base 2 may further include a second cover plate 22, which may be placed on the third assembly hole 211 and the fourth assembly hole 212. In the assembled state, the second cover plate 22 may protect the screws from corrosion by moisture and other substances in the air, thereby improving the durability and aesthetics of the locking member.
