Description

Technical Field

[0001] The present invention relates to the field of foldable structures, and in particular to an easily deployable structure and a foldable leg frame. Background Art

[0002] A folding chair generally comprises two hinged frame members, on which a front leg rod, a rear leg rod, a front seat rod and a back rod are inserted. The front leg rod and the front seat rod are connected by an elastic cable, and the rear leg rod and the back rod are connected by an elastic cable.

[0003] The front foot rod, rear foot rod, front seat rod and back rod can be removed from the frame member and can be folded relative to the frame member. After being folded, the front foot rod and the front seat rod are pulled together by an elastic cable, and the rear foot rod and the back rod are pulled together by an elastic cable. In this state, the front foot rod, rear foot rod, front seat rod and back rod are separated from the frame member. When the folding chair is unfolded, the front foot rod, rear foot rod, front seat rod and back rod need to be connected to the corresponding connecting parts on the frame member.

[0004] Through understanding the above related technologies, when the front leg rods, rear leg rods, front seat rods and back rods of the folding chair are transformed from the folded state to the unfolded state, it is necessary to manually align the insertion ends of each rod with the plug-in portion of the frame member so that the ends of the rods can be smoothly pulled into the plug-in interface of the frame member through the tension of the elastic cable. The folding leg frame of the folding chair generally contains more than eight rods, and each rod is relatively time-consuming when plugging in. Therefore, the entire unfolding operation process of the folding chair is relatively cumbersome. Summary of the Invention

[0005] The purpose of at least one specific embodiment of the present invention is to address the defects of the prior art and provide an easily deployable structure and a foldable leg stand.

[0006] To achieve the above objectives, the present application provides an easily deployable structure, comprising:

[0007] framing members;

[0008] a support rod rotatably mounted on the frame member;

[0009] a bendable elastic member disposed between the support rod and the frame member;

[0010] The frame member is provided with a plug-in portion, and the plug-in portion is provided with a plug-in interface;

[0011] One end of the support rod is an insertion end suitable for inserting into the insertion port;

[0012] The side of the plug-in portion is provided with a support guide portion, and the insertion end is provided with a sliding guide portion that cooperates with the support guide portion; wherein,

[0013] The elastic member is in a stretched energy storage state when the support rod is in a folded and retracted state, and when the external constraint is released:

[0014] The elastic member releases the tension to drive the support rod to rotate around the frame component, so that the sliding guide portion slides along the support guide portion, guiding the insertion end to align with and insert into the insertion port.

[0015] Furthermore, the support guide portion includes a plane guide segment and an arcuate guide segment, and the end of the arcuate guide segment is smoothly connected with the plug interface;

[0016] During the unfolding of the support rod, the sliding guide portion sequentially contacts the planar guide section and the arcuate guide section, and guides the insertion end to rotate along a preset trajectory and be introduced into the insertion port through the arcuate guide section.

[0017] Furthermore, the plug-in portion is provided with a guide groove, one end of which is connected to the plug-in port;

[0018] When the support rod is folded, the elastic member is at least partially located in the guide groove;

[0019] During the unfolding of the support rod, the guide groove guides the elastic member to move toward the insertion port in a directional manner.

[0020] Furthermore, the guide groove is formed at the support guide portion, and an inner wall of the guide groove is at least partially formed by an arcuate guide segment of the support guide portion.

[0021] Another easily deployable structure provided by this application includes:

[0022] framing members;

[0023] a support rod rotatably mounted on the frame member;

[0024] an elastic member connecting the support rod and the frame member;

[0025] The frame member is provided with a plug-in portion, and the plug-in portion is provided with a plug-in interface;

[0026] One end of the support rod is an insertion end, suitable for inserting into the insertion port;

[0027] A support guide portion is provided on the side of the plug-in portion, and the surface of the support guide portion includes an arc-shaped guide segment;

[0028] The insertion end is provided with a sliding guide portion that slides with the arc surface guide section;

[0029] a guide groove, which is provided on the supporting guide portion and has one end connected to the plug interface;

[0030] in:

[0031] The guide groove is suitable for accommodating the elastic member and restricting its movement path;

[0032] The end of the arc-surface guide section is smoothly connected with the plug-in interface;

[0033] When the elastic member contracts, the sliding guide portion is driven to slide along the arcuate guide section. The arcuate shape of the arcuate guide section enables the support rod to slide closely against its surface during the flipping process, so that the insertion end is inserted into the plug port according to a preset trajectory.

[0034] Furthermore, the inner wall of the guide groove is at least partially formed by the arc-surface guide segment.

[0035] Furthermore, the support guide portion further includes a plane guide section;

[0036] During the unfolding of the support rod, the sliding guide portion sequentially contacts the planar guide section and the arcuate guide section, and guides the insertion end to rotate along a preset trajectory and be introduced into the insertion port through the arcuate guide section.

[0037] Another easily deployable structure provided by the present application includes:

[0038] framing members;

[0039] a support rod rotatably mounted on the frame member;

[0040] an elastic member, disposed between the support rod and the frame member;

[0041] The frame member is provided with a plug-in portion, and the plug-in portion is provided with a plug-in interface;

[0042] One end of the support rod is an insertion end suitable for inserting into the insertion port;

[0043] A supporting guide portion is provided on the side of the plug-in portion, and a sliding guide portion that cooperates with the supporting guide portion is provided on the insertion end;

[0044] In which, the support rod has a first assembly state and a second assembly state relative to the frame component. When the support rod is converted from the second assembly state to the first assembly state, under the pulling force of the elastic member, the sliding guide part slides along the support guide part to guide the insertion end to align with and insert into the plug interface.

[0045] Further, when the support rod is in the first assembly state, the support rod is in an expanded state relative to the frame member;

[0046] When the support rod is in the second assembly state, the support rod is in a folded and retracted state relative to the frame component.

[0047] Furthermore, when the support rod is in a folded and retracted state relative to the frame component, the elastic member is in a stretched state. When the support rod is subjected to a binding restraining force, the folded and retracted state remains unchanged. When the binding restraining force disappears, the elastic member drives the support rod to flip over. After the insertion end is aligned with and inserted into the insertion port, the support rod is in an expanded state relative to the frame component.

[0048] Furthermore, a guide groove is provided on the plug-in portion, one end of which is communicated with the plug-in port. When the support rod rotates relative to the plug-in portion, it can drive the elastic member into or out of the guide groove.

[0049] Furthermore, the support guide portion is provided on the plug-in portion and faces one side of the frame member; when the support rod is converted from the first assembly state to the second assembly state, the support rod rotates toward the surface of the frame member to form a compact retracted state.

[0050] Furthermore, the support guide portion includes a plane guide segment and an arcuate guide segment, the arcuate guide segment is engaged with the plug-in interface, and the surface of the sliding guide portion is an arcuate surface.

[0051] Furthermore, when the support rod is converted from the second assembly state to the first assembly state, the elastic member drives the insertion end to pass through the planar guide section and the arc guide section in sequence, and the insertion end flips along the trajectory of the arc guide section and is inserted into the plug interface.

[0052] Furthermore, the number of the plug-in parts is more than two, and the number of the support rods is consistent with the number of the plug-in parts.

[0053] Furthermore, one end of the elastic member extends into one of the support rods and is connected thereto, and the other end of the elastic member extends into the interior of the frame component and extends into the other support rod and is connected thereto.

[0054] Furthermore, a limiting step is provided on the inner wall of the plug-in port. When the insertion end is inserted into the plug-in portion and abuts against the limiting step, the limiting step limits the insertion stroke of the support rod.

[0055] The advantageous technical effect of the deployable structure provided by the present application over the prior art is that: the deployable structure is used for the connection position between the support rod and the frame member; under normal circumstances, the insertion end of the support rod is inserted into the plug-in portion of the frame member, the support rod is stopped relative to the plug-in portion, and the deployable structure is in the deployed state; when the deployable structure is folded, the insertion end of the support rod is pulled out from the plug-in portion, the support rod can rotate relative to the plug-in portion, the elastic member is smoothly introduced into the guide groove from the plug-in interface and is in a stretched state; when the deployable structure changes from the folded state to the deployed state, the elastic member is reset, and the tension of the elastic member Under the action of the elastic member, the sliding guide portion at the end of the support rod slides relative to the supporting guide portion on the side of the frame member until the insertion end of the support rod is inserted into the plug interface of the plug-in portion, thereby realizing automatic resetting of the support rod. After the easy-to-expand structure is used, during the conversion of the support rod from the folded state to the unfolded state, there is no need for manual docking between the insertion end of the support rod and the plug-in portion of the frame member. Under the pulling force of the elastic member, the sliding guide portion and the supporting guide portion slide together, and after the support rod is unfolded, its insertion end can automatically align with the plug-in portion, making the assembly between the support rod and the frame member convenient and efficient.

[0056] In addition, when the support rod changes from a folded state to an unfolded state, the elastic part is transferred from the guide groove to the plug-in interface and reset. The guide groove plays a resetting and guiding role for the elastic part, ensuring the stability of the tension direction of the elastic part. When the support rod is docked with the plug-in part, the support rod is docked accurately and stably.

[0057] Another technical solution adopted in this application is to provide a folding leg stand, comprising:

[0058] Frame members of the above-mentioned deployable structure;

[0059] The frame members are hinged to each other;

[0060] A front foot bar, a rear foot bar, a front seat bar, and a rear back bar plugged into the frame member;

[0061] a first elastic member, one end of which extends into and is connected to the front foot rod, and the other end of which extends into and is connected to the front seat rod;

[0062] One end of the second elastic member extends into and is connected to the rear foot rod, and the other end extends into and is connected to the back rod.

[0063] Furthermore, when the front foot bar and the front seat bar are folded relative to the frame member, the first cable is in an elastically stretched state;

[0064] When the rear foot bar and the back bar are folded relative to the frame member, the second cable is in an elastically stretched state.

[0065] Furthermore, the front foot rod, the rear foot rod, the front seat rod, and the back rod are constructed as support rods of the above-mentioned easily deployable structure.

[0066] The folding leg stand provided in the present application adopts the above-mentioned easy-to-expand structure. The front foot rod, rear foot rod, front seat rod and back rod of the folding leg stand can be constructed as support rods of the above-mentioned easy-to-expand structure. The front foot rod, rear foot rod, front seat rod and back rod can be freely folded or unfolded relative to the frame component. When the front foot rod, rear foot rod, front seat rod and back rod are plugged into the plug-in part on the frame component, each rod can also be automatically aligned and automatically inserted with the plug-in part on the frame component, and the assembly between each rod and the frame component is convenient and efficient.

[0067] Another technical solution adopted in this application is to provide a storage box rack, comprising:

[0068] The above-mentioned deployable structure;

[0069] Support legs plugged into the frame member;

[0070] a support block provided on the frame member;

[0071] The support block is suitable for placing a storage box.

[0072] Furthermore, the supporting feet are constructed as supporting rods of the deployable structure.

[0073] Through the above technical solution, the support legs of the storage box rack can be freely folded or unfolded relative to the frame member. When the support legs are plugged into the plug-in parts on the frame member, each support leg can also be automatically aligned and automatically inserted with the plug-in parts on the frame member. The assembly between each support leg and the frame member is convenient and efficient.

[0074] Another technical solution adopted in this application is to provide a table, comprising:

[0075] The above-mentioned deployable structure;

[0092] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0093] Example 1

[0094] Reference Figure 1 , Figure 2 , Figure 3A deployable structure 100 includes a frame member 10, a support rod 20 rotatably mounted on the frame member 10, and an elastic member 30 disposed between the support rod 20 and the frame member 10, wherein the frame member 10 is provided with a plug-in portion 101, the plug-in portion 101 having an inserting port 102, one end of the support rod 20 being an insertion end 201, and the insertion end 201 being adapted to be inserted into the inserting port 102 of the plug-in portion 101;

[0095] In this embodiment, a support guide portion 40 is provided on the side of the plug-in portion 101 , and a sliding guide portion 202 corresponding to the support guide portion 40 is provided on the insertion end 201 .

[0096] The support rod 20 has a first assembly state and a second assembly state relative to the frame member 10. When the support rod 20 is converted from the second assembly state to the first assembly state, under the pulling force of the elastic member 30, the sliding guide portion 202 slides along the support guide portion 40, guiding the insertion end 201 to align with and insert into the plug port 102.

[0097] Specifically, when the support rod 20 is in the first assembly state, the support rod 20 is in an unfolded state relative to the frame member 10 ; when the support rod 20 is in the second assembly state, the support rod 20 is in a folded and retracted state relative to the frame member 10 .

[0098] In addition, when the support rod 20 is in a folded and retracted state relative to the frame member 10, the elastic member 30 is in a stretched state. When the support rod 20 is subjected to a binding constraint force, the folded and retracted state remains unchanged. When the binding constraint force disappears, the elastic member 30 drives the support rod 20 to flip over. After the insertion end 201 is aligned with and inserted into the insertion port 102, the support rod 20 is in an unfolded state relative to the frame member 10.

[0099] Further, refer to Figure 2 A guide groove 103 is provided on the plug-in portion 101 , one end of the guide groove 103 is connected to the plug-in port 102 , and when the support rod 20 rotates relative to the plug-in portion 101 , it can drive the elastic member 30 into or out of the guide groove 103 .

[0100] When the support rod 20 is unfolded or folded, the elastic member 30 will be driven into or out of the guide groove 103, which can play a fool-proof effect. The user can intuitively understand that the rotation and folding direction of the support rod 20 is toward the frame member 10. Moreover, after the support rod 20 is folded, it is in contact with the surface of the frame member 10 to form a bundle shape. In this embodiment, the number of the plug-in parts 101 on the frame member 10 is more than two, and the number of the support rods 20 plugged into the frame member 10 is more than two. When the number of the support rods 20 is multiple, the multiple support rods 20 can be folded and in contact with the surface of the frame member 10, which can reduce the volume of the entire structure after folding, which is convenient for bundling and restraint.

[0101] Furthermore, the support guide portion 40 includes a planar guide section 401 and an arcuate guide section 402, and the arcuate guide section 402 is connected to the plug-in interface 102, wherein the surface of the sliding guide portion 202 is an arcuate surface. When the support rod 20 is converted from a folded and retracted state to an unfolded state, the elastic member 30 drives the insertion end 201 to pass through the planar guide section 401 and the arcuate guide section 402 in turn, and the insertion end 201 flips along the trajectory of the arcuate guide section 402 and is inserted into the plug-in interface 102, thereby realizing automatic alignment and automatic insertion of the support rod 20 and the plug-in portion 101 of the frame component 10, and the assembly between each support rod 20 and the frame component 10 is convenient and efficient.

[0102] Furthermore, the elastic member 30 is preferably an elastic cable, one end of the elastic member 30 extends into a support rod 20 and is connected thereto, and the other end of the elastic member 30 extends into the interior of the frame member 10 and extends into another support rod 20 and is connected thereto, wherein the elastic member 30 extending into the support rod 20 passes through the sliding guide portion 202.

[0103] In this embodiment, refer to Figure 1 , Figure 2 , Figure 4 The easily deployable structure 100 includes a folded state and an unfolded state. When the insertion end 201 is inserted into the plug-in portion 101, the support rod 20 stops relative to the plug-in portion 101. At this time, the easily deployable structure 100 is in the unfolded state.

[0104] When the insertion end 201 is pulled out from the plug-in portion 101, the support rod 20 can rotate relative to the plug-in portion 101. At this time, the easily deployable structure 100 is in a folded state, and at the same time, the elastic member 30 is in a stretched state.

[0105] Specifically, when the easily deployable structure 100 changes from the deployed state to the folded state, the insertion end 201 is pulled out from the plug-in portion 101, and then the support rod 20 is rotated, the support rod 20 is in the folded state, and the elastic member 30 is introduced into the guide groove 103. At the same time, the elastic member 30 is in a stretched state.

[0106] When the easily deployable structure 100 changes from a folded state to an unfolded state, under the pulling force of the elastic member 30, the support rod 20 rotates toward the frame member 10, and the sliding guide portion 202 at the end of the support rod 20 slides relative to the support guide portion 40 until the insertion end 201 of the support rod 20 is inserted into the plug-in portion 101, and the support rod 20 is completely in an unfolded state. Since the support guide portion 40 includes a plane guide section 401 and an arcuate guide section 402, the arcuate guide section 402 is connected to the plug-in interface 102. During the unfolding process of the support rod 20, the sliding guide portion 202 at its end contacts the plane guide section 401 and the arcuate guide section 402 in turn, and the arcuate guide section 402 can smoothly and continuously guide the sliding guide portion 202 into the plug-in interface 102.

[0107] In order to ensure the stability and strength of the support rod 20 after it is unfolded, refer to Figure 5 A limiting step 104 is provided on the inner wall of the plug-in port 102. When the insertion end 201 of the support rod 20 is inserted into the plug-in portion 101, the limiting step 104 limits the insertion stroke of the support rod 20. When the support rod 20 is subjected to pressure or supporting force, the support rod 20 limited by the limiting step 104 cannot be further inserted into the plug-in portion 101. The support rod 20 can be stably supported at the plug-in portion 101, but can be pulled out.

[0108] In summary, the deployable structure 100 is used for the connection position of the support rod 20 and the frame member 10. Under normal circumstances, the insertion end 201 of the support rod 20 is inserted into the plug-in portion 101 of the frame member 10, and the support rod 20 is stopped relative to the plug-in portion 101. At this time, the deployable structure 100 is in the deployed state; when the deployable structure 100 is folded, the insertion end 201 of the support rod 20 is pulled out from the plug-in portion 101, and the support rod 20 can rotate relative to the plug-in portion 101. The elastic member 30 is smoothly introduced into the guide groove 103 from the plug-in port 102 and is in a stretched state. When the deployable structure 100 changes from the folded state to the deployed state, the elastic member 30 is reset. Under the pulling force of the elastic member 30, the end of the support rod 20 The sliding guide portion 202 contacts the support guide portion 40 on the side of the frame member 10 and slides relative to the support guide portion 40 until the insertion end 201 of the support rod 20 is inserted into the insertion port 102 of the plug-in portion 101, thereby realizing the automatic reset of the support rod 20. After the easy-to-expand structure is used, during the conversion of the support rod 20 from the folded state to the unfolded state, there is no need for manual docking between the insertion end 201 of the support rod 20 and the plug-in portion 101 of the frame member 10. Under the pulling force of the elastic member 30, the sliding guide portion 202 and the support guide portion 40 are slidably matched. After the support rod 20 is unfolded, its insertion end 201 can be automatically aligned with the plug-in portion 101, and the assembly between the support rod 20 and the frame member 10 is convenient and efficient.

[0109] In addition, when the support rod 20 changes from a folded state to an unfolded state, the elastic member 30 is transferred from the guide groove 103 to the plug-in port 102 and reset. The guide groove 103 serves as a reset guide for the elastic member 30, ensuring the stability of the tension direction of the elastic member 30. When the support rod 20 is docked with the plug-in portion 101, the support rod 20 is docked accurately and stably.

[0110] Example 2

[0111] Reference Figure 6 , Figure 7 , a folding leg stand 200, comprising:

[0112] The frame member 10 of the above-mentioned deployable structure 100;

[0113] The frame members 10 are hinged to each other;

[0114] A front foot bar 201, a rear foot bar 202, a front seat bar 203, and a back bar 204 plugged into the frame member 10;

[0115] A first elastic member 205, one end of which extends into and is connected to the front foot rod 201, and the other end of which extends into and is connected to the front seat rod 203. The first elastic member 205 is preferably an elastic cable;

[0116] The second elastic member 206 has one end extending into and connected to the rear foot rod 202 and the other end extending into and connected to the back rod 204. The second elastic member 206 is preferably an elastic cable.

[0117] Furthermore, when the front foot bar 201 and the front seat bar 203 are folded relative to the frame member, the first elastic member 205 is in an elastically stretched state;

[0118] When the rear foot bar 202 and the back bar 204 are folded relative to the frame member 10 , the second elastic member 206 is in an elastically stretched state.

[0119] In this embodiment, the folding leg stand 200 adopts the easily deployable structure 100 in the above-mentioned embodiment 1. The front foot rod 201, the rear foot rod 202, the front seat rod 203, and the back rod 204 of the folding leg stand 200 are constructed as the support rod 20 in the above-mentioned embodiment 1. The front foot rod 201, the rear foot rod 202, the front seat rod 203, and the back rod 204 are connected to the frame member 10 using the easily deployable structure 100 in the above-mentioned embodiment 1. Each rod can be freely folded or unfolded relative to the frame member 10. When the front foot rod 201, the rear foot rod 202, the front seat rod 203, and the back rod 204 are plugged into the plug-in portion 101 on the frame member 10, each rod can also be automatically aligned and automatically inserted with the plug-in portion 101 on the frame member 10. The assembly between each rod and the frame member 10 is convenient and efficient.

[0120] It should be noted that the length of the back bar 204 is generally greater than that of other bars. Therefore, the back bar 204 can be formed by connecting multiple back bar units 2041. When the back bar 204 is folded and stored, the multiple back bar units 2041 can be separated and folded.

[0121] Of course, one or more of the front foot bar 201, the rear foot bar 202, the front seat bar 203, and the back bar 204 can be connected to the frame component 10 using the easily deployable structure 100 in the above-mentioned embodiment 1, and the easily deployable structure 100 can be installed on the folding leg frame 200 with other detachable structures.
