Description

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 that replaces handles to open and close cabinet doors. Unlike handles, which need to be mounted on the cabinet's surface, rebounders are mounted on the cabinet's side panels, adding a more aesthetically pleasing and streamlined finish. When the door is closed, the rebounder locks the panel by attracting an iron block and a magnet. Gently press the door, and the elastic mechanism inside the rebounder pushes the telescopic element out, which then springs the door open, allowing it to open.

[0003] However, magnets may become severely demagnetized after long-term use, resulting in doors and cabinets not closing tightly or failing to lock.

[0112] 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.

[0113] 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.

[0114] The following provides an explanation of the terms used in this application.

[0115] 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.

[0116] 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:

[0117] A rebounder is a commonly used furniture hardware component. The rebounder known to the applicant consists of an elastic mechanism and a magnet. When closing the door, the rebounder attracts the door panel with the magnet, locking it. When opening the door, the rebounder uses the elastic mechanism to provide power to spring the door open. However, the magnet may gradually lose its magnetic properties over time, becoming severely demagnetized, which can cause the door panel to not close properly or fail to lock.

[0118] To this end, the present invention provides a technical solution for a rebounder. The rebounder provided in this embodiment utilizes a snap-fit structure to lock the door panel, eliminating the need for iron blocks and magnets. This prevents loose door closures and door lock failures caused by demagnetization, effectively improving the rebounder's service life and user experience. See below for details.

[0119] 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.

[0120] like Figures 1 to 3 As shown, the rebounder may include a locking base 1, and the locking base 1 may be fixed to a locking member 2 installed on the door panel by adopting a snap-fit structure, thereby fixing the door panel.

[0121] The respective structures and matching relationship of the locking base 1 and the locking member 2 will be described below.

[0122] Lock the base 1 and install it on the side panel.

[0123] The locking member 2 can be installed on the inner side of the door panel.

[0124] The locking base 1 may include a clamping portion 13, and the clamping portion 13 may include a closable claw 131. The claw 131 is used to clamp the locking member 2 located on the door panel, so that the locking base 1 locks the locking member 2.

[0125] In this embodiment, when the door panel rotates to a predetermined position, the locking member 2 approaches the locking base 1 and is clamped by the claw 131, so that the locking base 1 and the locking member 2 are engaged and fixed, thereby locking the door panel. In this embodiment, the rebounder uses a snap-fit structure to cooperate with each other to lock the door panel, eliminating the need for iron blocks and magnets. This prevents the door panel from being loosely closed and locking failures caused by demagnetization, effectively improving the service life of the rebounder and the user experience.

[0126] In some embodiments, as Figure 13 As shown, the locking base 1 may further include a housing 11, which may include a first assembly hole 111 and a second assembly hole 112. The first assembly hole 111 and the second assembly hole 112 may be provided for screws to pass through. The installer may secure the locking base 1 to the side panel using screws. Of course, other methods may also be used to secure the locking base 1 to the side panel, and this may be determined based on actual needs and is not limited thereto.

[0127] In actual applications, the installation position of the locking base 1 or the locking member 2 may deviate from the predetermined position, which may cause the locking member 2 to be misaligned with the locking base 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.

[0128] In an optional embodiment, the locking member 2 may include a base 21 and a rotating column 23 .

[0129] like Figure 4 As shown, the base 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 first flange 2321, a second flange 2322, and a first circumferential groove 2323 located between the first flange 2321 and the second flange 2322.

[0130] The snap ring 2131 and the first circumferential groove 2323 engage to confine the rotating column 23 on the base 21. The diameter of the first circumferential groove 2323 is smaller than the inner diameter of the snap ring 2131, and the second flange 2322 is larger than the inner diameter of the snap ring 2131. The second flange 2322 is movably confined between the snap ring 2131 and the door panel.

[0131] 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 member 2 or the locking base 1, thereby improving the practicality and convenience of the rebound device.

[0132] In some embodiments, the base 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 member 2 to the door panel using screws. Alternatively, welding or other methods can be used to secure the locking member 2 to the door panel. This method is not limited to the above and is selected based on actual needs.

[0133] In some embodiments, the locking member 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.

[0134] The above embodiment has described in detail the structure and component matching relationship of the locking member 2. The structure and component matching relationship of the locking base 1 will be described below.

[0135] like Figure 1As shown, the locking base 1 may include a shell 11 , a sleeve 12 , a core and a first cover plate 18 .

[0136] The sleeve 12 is used to accommodate the core and is accommodated in the housing 11. The first cover 18 can be provided on the housing 11 to protect the sleeve 12 and the core.

[0137] The core body may include a sliding portion, a hook portion 16 and a spring 17. The spring 17 is supported between the sliding portion and the hook portion 16.

[0138] The sliding portion may include a clamping portion 13, a first fixing portion 14, and a second fixing portion 15 that are sequentially connected. The clamping portion 13 and the first fixing portion 14 are fixedly connected, and the first fixing portion 14 and the second fixing portion 15 are connected.

[0139] The structure and component matching relationship of the locking base 1 will be described in detail below with reference to more drawings.

[0140] In an optional embodiment, the locking base 1 may further include a core and a sleeve 12. The sleeve 12 may accommodate the core, and the sleeve 12 is accommodated in the housing 11.

[0141] like Figure 1 As shown in FIG. 3 , the core includes a sliding portion, and the end of the sliding portion facing the locking member 2 is provided with the claw 131. A slide rail can be formed inside the sleeve 12 to allow the sliding portion to slide axially, thereby adjusting the degree of opening and closing of the claw 131.

[0142] In this embodiment, the sliding portion can slide axially into and out of the sleeve 12. When sliding into the sleeve 12, the claws 131 contract under the constraints of the inner wall of the sleeve 12. When sliding out of the sleeve 12, the claws 131 expand. The degree of opening and closing of the claws 131 can be effectively adjusted through the sleeve 12, thereby locking and releasing the locking member 2.

[0143] In some embodiments, the end of the sliding portion facing the locking member 2 may be further provided with two opposite through holes for allowing the two claw feet of the claw 131 to extend.

[0144] The following will introduce the structure of the sliding part and the matching relationship of the components.

[0145] In an optional embodiment, the sliding portion may include a first fixing portion 14 and a second fixing portion 15 .

[0146] like Figure 5 As shown, one end of the first fixing portion 14 can extend out of the sleeve 12, and the other end is located in the sleeve 12. The second fixing portion 13 is located in the sleeve 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.

[0147] 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.

[0148] In this embodiment, the screw structure can provide a door gap adjustment range of 5 mm. It should be noted that the screw structure can be appropriately adjusted according to actual needs to provide different door gap adjustment ranges, which is not limited here.

[0149] 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.

[0150] In an optional embodiment, if Figure 6 As shown in FIG-8 , the first fixing portion 14 may further include a limiting block 142, which is located on the inner wall of the first fixing portion 14. In some embodiments, there may be two limiting blocks, which are positioned opposite to each other.

[0151] Correspondingly, if Figure 7A - Figure 7B As shown, the clamping portion 13 may also be provided with at least two opposing fixed claws 132 with a gap therebetween. The fixed claws 132 are located at the end of the clamping portion facing away from the locking member 2. An inclined portion 1321 is provided on the outer side of the free end of the fixed 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 fixed claws 132 so that the fixed claws 132 extend into the first fixing portion 14. The recessed snap 1322 is used to engage with the stop block 142 for securement.

[0152] 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 142. At this time, the inclined portions 1321 of the two fixing claws 132 are against the limit block 142. 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 shapes of the concave bayonet 1322 and the limit block 142 are adapted to engage, 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.

[0153] In some embodiments, the stopper 142 may have an inclined surface 1421 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 elasticity of the plastic. 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.

[0154] 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.

[0155] In an optional embodiment, if Figure 9 As shown in FIG. 10 , the second fixing portion 15 may further include a semi-cylindrical arc surface 152 and a third flange 153. The semi-cylindrical arc surface 152 is formed by extending from the second end of the second fixing portion 15. The third flange 153 is located at the bottom of the semi-cylindrical arc surface 152. The core body may further include a hook portion 16 and a spring 17. The hook portion 16 may include a hook 161 and a hook fixing seat 162. The hook 161 is fixed to the hook fixing seat 162. The hook fixing seat 162 is fixed to the end of the sleeve 12 away from the locking member 2. The spring 17 is supported between the hook fixing seat 162 and the third flange 153.

[0156] 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.

[0157] In this embodiment, under the action of a 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 sleeve 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 sleeve 12, and the claw 131 releases the locking member 2, thereby achieving the opening of the door panel.

[0158] 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.

[0159] In an optional embodiment, if Figure 9 As shown in Figure 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 sequentially connected. The first passage 1522 is formed by the gap between the first sidewall of the Y-shaped boss 1521 and the corresponding side edge of the semi-cylindrical arc surface 152, allowing the hook 161 to slide onto the first inclined surface 1523. The first inclined surface is used to guide the hook 161 into the first U-shaped groove 1524. The first U-shaped groove 1524 is used to guide the hook 161 into the middle fork of the Y-shaped boss.

[0160] 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 .

[0161] 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 sleeve 12, thereby 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 sleeve 12, and the claw 131 releases the locking member 2, thereby opening the door panel.

[0162] 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.

[0163] 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.

[0164] In an optional embodiment, if Figure 11 As shown, 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 161 may include a hook 1611 and a hook rod 1612. The hook 1611 and the hook rod 1612 are fixedly connected. Part of the side wall of the hook rod 1612 is close to the fixing plate 1621. A first protrusion 1624 and a second protrusion 1625 may be provided on the fixing plate 1621. The first protrusion 1624 and the second protrusion 1625 are respectively provided on both sides of the hook rod 1612, and the first protrusion 1624 and the second protrusion 1625 are used together to limit the swing range of the hook rod 1612.

[0165] 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.

[0166] In an optional embodiment, if Figure 11 As shown, 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.

[0167] 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.

[0168] In an optional embodiment, if Figure 11 As shown in FIG. 12 , a deformable protrusion 1627 is provided on the end of the circular base 1622 facing the locking member 2. Correspondingly, a deformable recess 121 is provided on the end of the sleeve 12 away from the locking member 2. The deformable protrusion 1627 and the deformable recess 121 cooperate to securely engage the sleeve 12 and the circular base 1622.

[0169] In this embodiment, the hook fixing seat 162 is fixed to the end of the sleeve 12 by the cooperation between the deformed protrusion 1627 and the deformed recess 121 .

[0170] In an optional embodiment, if Figure 1 As shown in Figure 13, the sleeve is provided with a first pin hole 122, which is located at the end of the sleeve 12 away from the locking member 2. The free end of the hook 161 is provided with a circular 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. The first pin hole 122, the arc-shaped hole 1628, the circular through hole 1613, and the second pin hole 1626 are positioned correspondingly. The pin shaft 19 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 and spans the two sides of the sleeve 12, thereby fixing the hook portion 16 to the sleeve 12.

[0171] In this embodiment, the hook portion 16 is fixed in the sleeve 12 by pinning, thereby improving the structural stability of the rebounder.

[0172] It should be noted that other methods may also be used to fixedly connect the hook portion 16 and the sleeve 12 , which can be selected based on actual needs and is not limited here.
