Description

Technical Field

[0001] This invention relates to the field of furniture, and more particularly to a storage cabinet. Background Technology

[0002] In related technologies, drawers are often slidably connected to the cabinet body via slide rails and sliders, facilitating their pulling out and retraction. When the drawer is retracted, its outer panel is flush with the cabinet surface, making it difficult for the user to find the point of application for pulling when retrieving items again. To address this issue, existing technologies often use hardware fasteners on the drawer's outer panel, using these fasteners as the point of application for pulling, thus facilitating the drawer's extension. However, these hardware fasteners disrupt the simplicity and consistency of the storage cabinet, making them less aesthetically pleasing. Furthermore, because the hardware fasteners protrude from the outer panel surface, the user's head is susceptible to bumping into them, posing a safety hazard. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a storage cabinet. The storage cabinet of this application adopts a drawer with a push-to-open function, which eliminates the need to install hardware fasteners on the outer panel of the drawer and has a higher aesthetic appeal.

[0004] A storage cabinet according to a first aspect of the present invention includes:

[0005] The cabinet has storage compartments;

[0006] drawer;

[0007] The sliding device includes a first sliding member connected to the cabinet body and a second sliding member connected to the drawer. The drawer and the cabinet body are slidably connected by the cooperation of the first sliding member and the second sliding member. The drawer can switch between a retracted position and an extended position. The direction of the drawer from the retracted position to the extended position is set as the extended direction, and the direction of the drawer from the extended position to the retracted position is set as the retracted direction.

[0008] The rebound device includes a limiting guide rail and a drive assembly. The limiting guide rail is connected to the bottom plate of the drawer and extends toward the extension direction. The limiting guide rail includes an abutment portion. The drawer has a central axis extending along the extension direction. The limiting guide rail is configured such that the distance between the abutment portion and the central axis gradually increases, or the distance between the abutment portion and the central axis gradually decreases. The drive assembly is disposed on the cabinet body and includes a movable member, an elastic member, and a fixed seat. The movable member abuts against the abutment portion. In response to the drawer switching from the extended position to the retracted position, the movable member can slide relative to the fixed seat perpendicular to the extension direction and cause the elastic member to elastically deform.

[0009] The locking device includes a first limiting member connected to the fixed base and a second limiting member connected to the drawer. The first limiting member has a limiting groove, and the second limiting member includes a limiting protrusion.

[0010] The limiting protrusion can move along the retraction direction to be inserted into the limiting groove, so that the second limiting member is engaged with the first limiting member, the elastic member remains in a deformed state, and the limiting protrusion can move along the retraction direction to release the engagement state of the first limiting member and the second limiting member, and the elastic member drives the drawer to extend out of the storage cavity.

[0011] The storage cabinet according to embodiments of the present invention has at least the following advantages: The storage cabinet of this embodiment uses a drawer with a push-to-open function, eliminating the need for hardware fasteners on the outer side panel of the drawer, thus improving aesthetics. Furthermore, the outer side panel of the drawer has no protruding structures, preventing the user's head from bumping against the fasteners. Since the sliding device supporting the drawer's sliding, the rebound device for the push-to-open function, and the locking device independently perform their functions, each component can be replaced individually, resulting in lower maintenance costs. In addition, when the drawer is pressed, the storage cabinet of this application only needs to trigger the locking device to release the locking state of the first and second limiting members to extend the drawer; the push-to-open function has a high trigger success rate and a good trigger feel.

[0012] According to some embodiments of the present invention, the number of limiting guide rails is one, the number of movable parts is one, one end of the elastic part away from the limiting guide rail is fixedly connected to the fixed base, and the other end is movably abutted against the abutting part of the limiting guide rail through the movable part. Along the retraction direction, the distance from the abutting part to the fixed end of the elastic part gradually decreases in the sliding direction of the movable part. The movable part is located on the side of the limiting guide rail close to the fixed end of the elastic part. When the drawer is retracted, the elastic part is in a compressed state.

[0042] This application discloses a storage cabinet, including a cabinet body 100 and a drawer 110. Sliding devices (not shown in the figure) are provided on the opposite panels of the drawer 110 and the cabinet body 100. The sliding devices include a first sliding member connected to the cabinet body 100 and a second sliding member connected to the drawer 110. The drawer 110 and the cabinet body 100 are slidably connected through the cooperation of the first and second sliding members. For example, the first sliding member is a guide rail, and the second sliding member is a pulley. Specifically, pulleys are provided on the side panels of the drawer 110 along the pull-out direction, and guide rails are provided on the opposite side panels of the cabinet body 100. The pulleys and guide rails slide against each other to reduce the frictional resistance when the drawer 110 and the cabinet body 100 slide relative to each other, so that the drawer 110 can smoothly extend or retract from the cabinet body 100. This type of drawer 110 equipped with guide rails and pulleys is quite common and will not be described in detail here.

[0043] like Figure 1 and Figure 2 As shown, to avoid drilling holes in the outer panel 111 of drawer 110 for installing hardware handles and to improve the aesthetics of the storage cabinet, a rebound device and a locking device are installed inside drawer 110. This allows pressing the outer panel of drawer 110 to trigger the rebound device, driving drawer 110 to extend. Specifically, the rebound device includes a limiting guide rail 200 and a drive assembly 300. The limiting guide rail 200 is connected to drawer 110 and extends in the direction of drawer 110's extension. Figure 3 As shown, the limiting guide rail 200 includes an abutment portion 210 for limiting and abutting the movable part 310 of the drive assembly 300. The specific shape of the limiting guide rail 200 can be a long strip of equal thickness, forming an angle greater than 0° and less than 90° with the extension direction of the drawer 110 on the horizontal plane; or it can be a cone of varying thickness, with the distance between the two sides of the cone gradually increasing or decreasing along the extension direction. The specific shape of the limiting guide rail 200 is not limited here, but at least the abutment portion 210 of the limiting guide rail 200 should not be parallel to the extension direction of the drawer 110. That is, with the central axis of the drawer 110 as a reference, as the central axis extends along the extension direction, the distance between the abutment portion 210 of the limiting guide rail 200 and the central axis should gradually increase, or the distance between the abutment portion 210 and the central axis should gradually decrease.

[0044] like Figure 2 He Ru Figure 4 As shown, the drive assembly 300 is mounted on the cabinet 100. The drive assembly 300 includes a movable member 310, an elastic member 320, and a fixed base 330. The movable member 310 is connected to the elastic member 320 and can slide relative to the fixed base 330. When the drawer 110 is retracted, due to the inclined setting of the limiting guide rail 200, the movable member 310 is driven by the limiting guide rail 200 and slides along the extending direction of the elastic member 320, thereby causing the elastic member 320 to undergo elastic deformation. Figure 2 As shown, in this embodiment, the limiting guide rail 200 is disposed on the bottom plate of the drawer 110, and the driving component 300 is disposed on the drawer 110 of the bottom plate of the cabinet 100. Furthermore, the limiting guide rail 200 is located in the middle of the drawer 110, and the driving component 300 is located in the middle of the cabinet 100. It can be understood that the specific placement and connection relationship of the driving component 300 and the limiting guide rail 200 can be adjusted according to design requirements.

[0045] For ease of subsequent description, such as Figure 1 As shown, the extension direction of drawer 110 is set as the first direction 600, the retraction direction of drawer 110 is set as the second direction 610, and the sliding direction of movable part 310 is set as the third direction 620.

[0046] by Figures 1 to 5 Taking the illustrated embodiment as an example, the rebound device in this embodiment includes two limiting guide rails 200 and two movable members 310. The two ends of the elastic member 320 respectively movably abut against the contact portions 210 of the limiting guide rails 200 through the movable members 310. Along the second direction 610, the distance between the two contact portions 210 gradually increases. The two movable members 310 are respectively located on opposite sides of the limiting guide rails 200. The area between the two limiting guide rails 200 is defined as the inner side, and the area outside the two limiting guide rails 200 is defined as the outer side. That is, the movable member 310 is located on the inner side of the limiting guide rails 200, and the movable member 310 movably abuts against the contact portion 210. When drawer 110 is retracted, the movable part 310 moves relative to the limiting guide rail 200 in the second direction 610 as the drawer 110 moves. The movable part 310 moves from the end with a larger gap to the end with a smaller gap on the limiting guide rail 200. As a result, the movable parts 310 move towards each other driven by the limiting guide rail 200. The gap between the two movable parts 310 gradually decreases. The elastic part 320 located between the two movable parts 310 is compressed and undergoes elastic deformation, switching to a compressed state.

[0047] In other embodiments, the rebound device also includes two limiting guide rails 200 and two movable members 310. Along the second direction 610, the distance between the two abutting portions 210 gradually decreases. The two movable members 310 are located on opposite sides of the limiting guide rails 200, that is, the movable members 310 are located on the outer side of the limiting guide rails 200 (not shown in the figure). When the drawer 110 is retracted, the movable members 310 move relative to the limiting guide rails 200 in the second direction 610 as the drawer 110 moves. The movable members 310 move from the end with the smaller distance between the limiting guide rails 200 to the end with the larger distance. Driven by the limiting guide rails 200, the movable members 310 move in opposite directions, and the distance between the movable members 310 gradually increases. The two ends of the elastic member 320 are respectively connected to the movable members 310, causing the elastic member 320 to undergo elastic deformation and switch to a stretched state.

[0048] After drawer 110 is retracted, since the elastic element 320 is in a compressed or stretched state, it tends to return to its initial state, i.e., it tends to drive drawer 110 out. Therefore, the storage cabinet of this application also includes a locking device capable of maintaining the deformed state of the elastic element 320 so that drawer 110 is accommodated in the storage cavity. The locking device includes a first limiting member 400 and a second limiting member 500, which connect drawer 110 and cabinet body 100, keeping drawer 110 in the retracted state, i.e., keeping elastic element 320 in the deformed state.

[0049] Specifically, such as Figure 4 and Figure 5 As shown, the first limiting member 400 is connected to the fixing base 330, and the first limiting member 400 has a limiting groove. The second limiting member 500 is connected to the drawer 110 and includes a limiting protrusion 510. When the drawer 110 is pulled back, the limiting protrusion 510 can move along the second direction 610 to insert into the limiting groove, so that the second limiting member 500 engages with the first limiting member 400, thereby connecting the drawer 110 and the cabinet 100, so that the elastic member 320 remains in a deformed state. When it is necessary to open the drawer 110 to store items, press the outer side panel 111 of the drawer 110 so that the limiting protrusion 510 can continue to move along the second direction 610, so that the engaging state of the first limiting member 400 and the second limiting member 500 is released, the elastic member 320 returns to its initial state, thereby driving the drawer 110 to extend out of the storage cavity.

[0050] like Figure 1 and Figure 2As shown, taking an embodiment where the rebound device includes two limiting guide rails 200 and a movable member 310, with the movable member 310 located inside the limiting guide rails 200 as an example, when the drawer 110 retracts, the elastic member 320 switches to a compressed state, tending to return to its initial state, pushing the drawer 110 to engage with the first limiting member 400 and the second limiting member 500. At this time, the drawer 110 is retracted into the storage cavity. Pressing the outer side panel 111 of the drawer 110 allows the limiting protrusion 510 to continue moving along the second direction 610. When the engagement of the first limiting member 400 and the second limiting member 500 is released, the elastic member 320 recovers its deformation, increasing the distance between the two movable members 310. Since the movable member 310 is abutted and limited by the limiting guide rails 200, it is further prompted to move relative to the limiting guide rails 200 to the end with a larger gap, thus causing the drawer 110 to extend.

[0051] Based on the above, the storage cabinet of this application adopts a drawer 110 with a push-to-open function, eliminating the need to install hardware fasteners on the outer panel 111 of the drawer 110, thus improving its aesthetics. Furthermore, the outer panel 111 of the drawer 110 has no protruding structure, preventing the user's head from bumping against the fasteners. Since the sliding device supporting the sliding motion and the rebound device and locking device for the push-to-open function of the drawer 110 function independently, each component can be replaced individually, resulting in lower maintenance costs. In addition, when the drawer 110 is pressed, the storage cabinet of this application only needs to trigger the locking device to release the locking state of the first limiting member 400 and the second limiting member 500 to extend the drawer 110. Compared to related technologies where the push-to-open guide rails on both sides of the drawer 110 must be triggered, the single-point triggering locking device of this application improves the success rate and tactile feedback of the push-to-open function.

[0052] In some embodiments, the number of limiting guide rails 200 may be one, and the number of movable members 310 may be one. The end of the elastic member 320 away from the limiting guide rail 200 is fixed, while the other end is movably abutted by the movable member 310 and the abutment portion 210 of the limiting guide rail 200. Along the second direction 610, the distance from the abutment portion 210 to the fixed end of the elastic member 320 gradually decreases in the third direction 620, and the movable member 310 is located on the side of the limiting guide rail 200 near the fixed end of the elastic member 320. Furthermore, when the drawer 110 retracts, the distance between the contact position of the movable member 310 and the abutment portion 210 and the fixed end gradually decreases, causing the elastic member 320 to gradually compress, thus giving the elastic member 320 a tendency to recover its deformation and drive the drawer 110 to extend. In other embodiments, along the second direction 610, the distance from the abutment portion 210 to the fixed end of the elastic member 320 gradually increases in the third direction 620, and the movable member 310 is located on the side of the limiting guide rail 200 away from the fixed end of the elastic member 320. Furthermore, when the drawer 110 retracts, the distance between the contact position of the movable member 310 and the abutment portion 210 and the fixed end gradually increases, causing the elastic member 320 to gradually stretch, thereby giving the elastic member 320 a tendency to recover its deformation and drive the drawer 110 to extend.

[0053] In some embodiments, such as Figure 4 As shown, the drive assembly 300 also includes a support shaft 340, which extends along a third direction 620. The fixed base 330 has support plates 331 at both ends along the third direction 620. The two ends of the support shaft 340 are respectively connected to the support plates 331 at both ends of the fixed base 330, thus mounting the shaft on the fixed base 330. Both the elastic element 320 and the movable element 310 pass through the support shaft 340, and the support shaft 340 guides the movement of the movable element 310.

[0054] In some embodiments, such as Figure 4As shown, the movable component 310 includes a slider 311, a roller 312, and a connecting shaft (not shown in the figure). The connecting shaft connects the slider 311 and the roller 312 together. The slider 311 passes through the support shaft 340 and can slide along the axial direction of the support shaft 340. The roller 312 and the contact portion 210 of the limiting guide rail 200 are in a rolling connection to reduce the frictional resistance between the movable component 310 and the limiting guide rail 200, making the retraction and extension of the drawer 110 smoother. The drive assembly 300 also includes a guide cover 350. The guide cover 350 has a through groove parallel to the support shaft 340. The roller 312 is located on the top surface of the guide cover 350, and the slider 311 is located inside the guide cover 350. The connecting shaft passes through the through groove. The guide cover 350 can cover the slider 311, the elastic element 320, and other components. In appearance, only the fixed base 330 and the guide cover 350 forming a box structure are visible, which is more aesthetically pleasing. On the other hand, the through groove can play an auxiliary limiting role in the sliding of the movable part 310, preventing the movable part 310 from being displaced in the first direction 600 or the second direction 610.

[0055] In some embodiments, the drive assembly 300 includes only one support shaft 340. When the slider 311 slides along a third direction 620 on the support shaft 340, the slider 311 has a degree of freedom to rotate axially along the support shaft 340. The groove on the guide cover 350 can restrict this degree of rotational freedom. In such cases... Figure 3 and Figure 4 In the illustrated embodiment, the abutment portion 210 is a narrow edge extending from the limiting guide rail 200, and the roller 312 has a recessed portion in the middle. The abutment portion 210 is embedded in the recessed portion. While sliding, the main structures on both sides of the roller 312 can also limit the abutment portion 210, reducing the possibility of the abutment portion 210 and the roller 312 disconnecting. In other embodiments, the drive assembly 300 may also include multiple support shafts 340, thereby enabling multiple elastic elements 320 to be provided, allowing the drawer 110 to extend smoothly even under heavy load. It is understood that the rebound force and rebound speed can also be adjusted by replacing the elastic elements 320 with different elastic coefficients.

[0056] In some embodiments, such as Figure 4 As shown, the movable part 310 also includes a slide rail sleeve 360 ​​that passes through the support shaft 340. Multiple balls are provided on the inner surface of the slide rail sleeve 360 ​​to facilitate the sliding connection between the slide rail sleeve 360 ​​and the support shaft 340, thereby reducing the friction between the movable part 310 and the support shaft 340.

[0057] In some embodiments, such as Figure 6 and Figure 7As shown, the limiting groove includes an inlet section 410, a limiting section 420, and an outlet section 430 connected in sequence. The limiting protrusion 510 can move unidirectionally along the direction from the inlet section 410 to the limiting section 420 to the outlet section 430. It should be noted that the first limiting member 400 includes a first main body portion 450 and a second main body portion 460. The second main body portion 460 is located on the opposite inner side of the first main body portion 450, and a limiting groove is defined between the first main body portion 450 and the second main body portion 460. Corresponding to the position of the limiting section 420, the second main body portion 460 is recessed inward toward the first direction 600. After the limiting protrusion 510 enters the limiting section 420, if the drawer 110 is not pushed further, the limiting protrusion 510 falls into the recess of the limiting section 420, so that the limiting protrusion 510 can be engaged in the limiting groove at the limiting section 420.

[0058] Specifically, such as Figure 7 As shown, the groove depth of the limiting segment 420 is greater than the groove depth of the leading segment 410, thus forming a first stepped surface 470 at the junction of the limiting segment 420 and the leading segment 410. When the limiting protrusion 510 moves to the limiting segment 420, it is blocked by the first stepped surface 470, and the limiting protrusion 510 cannot move from the limiting segment 420 to the leading segment 430. Along the direction of movement of the limiting protrusion 510 in the limiting groove, for ease of description, the two ends of the leading segment 430 are respectively set as the beginning end and the end end. The groove depth of the beginning end of the leading segment 430 is greater than the groove depth of the limiting segment 420, thus forming a second stepped surface 480 at the junction of the leading segment 430 and the limiting segment 420. When the limiting protrusion 510 moves to the beginning end of the leading segment 430, it is blocked by the second stepped surface 480, and the limiting protrusion 510 cannot move from the leading segment 430 to the limiting segment 420.

[0059] In such Figure 7In the illustrated embodiment, corresponding to the position of the limiting segment 420, the first main body portion 450 protrudes outward in the first direction 600 to cooperate with the second main body portion 460 being recessed in the first direction 600, forming a heart-shaped structure on the first limiting member 400. For ease of description, the limiting segment 420 is further divided into a first segment 421 and a second segment 422 connected in sequence, and the junction of the first segment 421 and the second segment 422 has a third stepped surface 490. When the user pushes the drawer 110 back along the second direction 610, until the limiting protrusion 510 moves to the position of the first segment 421, the limiting protrusion 510 abuts against the first main body portion 450, restricting further movement of the limiting protrusion 510 along the second direction 610. At this point, the user no longer applies force to push the drawer 110. The elastic element 320 drives the drawer 110 to move in the first direction 600 until the limiting protrusion 510 moves from the first segment 421 to the second segment 422 in the limiting groove. At the second segment 422, the limiting protrusion 510 is restricted by the second main body 460 and cannot move further along the second direction 610. At this point, the limiting protrusion 510 is engaged in the second segment 422 of the limiting groove, and the drawer 110 is in a retracted and locked state.

[0060] When drawer 110 needs to be opened to store items, press the outer side panel 111 of drawer 110 to move drawer 110 in the second direction 610. The limiting protrusion 510 is restricted by the third step surface 490 and can only move from the second section 422 to the first end of the exit section 430. At this time, the limiting protrusion 510 is restricted by the first main body 450 and cannot move further in the second direction 610. When the user stops pressing drawer 110, due to the setting of the second step surface 480, the limiting protrusion 510 cannot fall back into the second section 422 and can only slide out along the exit section 430. It should be noted that since drawer 110 needs to move further in the second direction 610 when pressed, a certain gap should be left between drawer 110 and cabinet 100 in the retracted state to accommodate the movement of drawer 110 when pressed. In this embodiment, the pressing stroke of the press-to-unlock structure can be reduced to about 1-3mm, which is much smaller than the pressing stroke of the push-to-unlock guide rail in related technologies. This helps to reduce the gap between the drawer 110 and the cabinet 100 and increase the capacity of the drawer 110.

[0061] In some embodiments, such as Figure 6 As shown, the first limiting member 400 also has a first opening 440, the inlet section 410 communicates with the first opening 440, and the limiting protrusion 510 can be inserted into the limiting groove from the first opening 440, so that the first limiting member 400 and the second limiting member 500 switch from a separated state to an inserted state, as shown in the figure. Figure 6In the illustrated embodiment, the inlet segment 410 and the outlet segment 430 are connected. The groove depth of the outlet segment 430 gradually decreases along the sliding direction of the limiting protrusion 510 until the groove depth at the end of the outlet segment 430 is less than the groove depth of the inlet segment 410. Then, an abutment surface 431 is defined at the junction of the outlet segment 430 and the inlet segment 410. The abutment surface 431 extends to abut against the groove wall of the inlet segment 410 to guide the movement of the limiting protrusion 510 along the second direction 610 and prevent the limiting protrusion 510 from inserting into the outlet segment 430 when it moves along the second direction 610.

[0062] In some embodiments, such as Figure 8 As shown, the dashed line indicates the position of the extension 530 when it swings. The second limiting member 500 includes a mounting bracket 520 and an extension 530. The mounting bracket 520 is used to connect with the drawer 110. The limiting protrusion 510 is provided on the extension 530. The extension 530 and the mounting bracket 520 are movably connected. On the horizontal plane, the limiting protrusion 510 can swing relative to the mounting bracket 520, and thus can swing with the bending of the limiting groove. It should be noted that the swing range of the extension 530 relative to the mounting bracket 520 is limited, that is, it swings to the left or right at a certain angle on the horizontal plane. To ensure that the limiting protrusion 510 can be smoothly inserted into the limiting groove when the drawer 110 is retracted, on the third direction 620, the projected length of the swing trajectory of the limiting protrusion 510 is less than the width of the first opening 440, so as to avoid the situation where the first limiting member 400 and the second limiting member 500 cannot be inserted, causing the drawer 110 to be unable to maintain the retracted state.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
