Description

[Technical field]

[0001] The present invention relates to a portable, collapsible table that is lightweight, can be stored compactly, and has a tabletop height above the ground suitable for use as a side table. [Background technology]

[0002] Conventionally, portable, collapsible tables have been used as camping tables, and many of these products achieve both stability and light weight by limiting the height of the tabletop above the ground to approximately 100 mm. Such tables can be stored in a backpack, improving portability. However, the seat height of lightweight chairs used with these tables is set to approximately 300 to 400 mm, and as a result, when using the table by stretching one's arms while seated, a problem occurs in that a table with a tabletop height of approximately 100 mm reduces operability. This is particularly noticeable when using the table as a side table. To use the table as a side table, it is desirable for the tabletop to be approximately 300 mm above the ground. Therefore, there is a need for a table that is lightweight and compact enough to be carried with a chair, yet stable enough and with a tabletop high enough to be used as a side table. A table that combines all of these elements is believed to contribute to improved convenience and operability.

[0003] The assembly table of Patent Document 1 is a lightweight, compact, portable assembly table, but since the height of the table top from the ground is low, it is not easy to operate as a side table. In addition, the folding camping table in Patent Document 2 has short legs that can be folded and stored inside the underside of the tabletop, and by providing extension legs for the short legs, the table can be made tall and used as a side table, but it is heavy and large. Therefore, it is difficult to store in a backpack, and it is not a lightweight and compact table. Therefore, there has been a demand for a portable, collapsible table that is lightweight and compact to store, and has a tabletop height above the ground suitable for use as a side table.

[0004] [Patent Document 1] Patent Publication No. 2013-70769 [Patent Document 2] Patent Publication No. 10-165229 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention provides a portable, collapsible table that is lightweight, can be stored compactly, and has a tabletop height above ground suitable for use as a side table. [Means for solving the problem]

[0006] This is a portable, collapsible table with a tabletop divided into two, with edges of an appropriate height on both longitudinal sides of the divided tabletop so that the legs can be stored, and one edge of the divided tabletop is connected by an axis so that it can be folded in half, and the legs can be stored on the underside of the tabletop.The legs have four leg bodies of a length that can fit inside the tabletop when stored, and an X-shaped reinforcement section made of flexible wire, the tabletop has insertion sections near the four vertices and a return section on the edge of the tabletop, and the legs have a claw section and an engaged section at each tip, and the claw sections are inserted into the insertion sections so that the return section and the engaged section engage.This is an assembly table characterized in that

[0007] The reinforcing part has four L-shaped bodies, each of which is composed of an upper side part and a lower foot part, the upper side parts of the four L-shaped bodies are rotatably connected to the center of the reinforcing part so as to cross in an X shape, and the base ends of the four legs are rotatably connected to the lower foot parts of the four L-shaped bodies, respectively, and when in use, the base ends of the four legs stand up so as to contact the ground and function as legs. The insertion part is provided so as to leave a gap when the claw part is inserted, and the engaged part is positioned so that the distance from the lower end of the claw part to the upper end of the engaged part is the same as the height of the edge of the tabletop. Effect of the Invention

[0008] The present invention provides a portable assembly table that is lightweight and can be stored compactly, yet has a tabletop height above the ground suitable for use as a side table. In other words, this storage mechanism and structure allows the table to be stored in a compact form that can be carried in a backpack, while still having a tabletop height suitable for use as a side table, and achieving truly practical stability. In addition, the top plate is punched to reduce its weight, improving portability. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] 1 is a perspective view showing the collapsible table of the present invention when stored. The table top 1 can be folded in half, and has two separate tables 11a and 11b. The legs 2 are stored on the underside of the tabletop 1. The tabletop 1 is preferably punched to reduce its weight. The material of the tabletop is preferably aluminum, but is not limited to this.

[0010] 2 is a perspective view showing the collapsible table when the top plate is open for storage. The top plate 11a has edges 12a and 12a' on the two long sides of the top plate at an appropriate height so that the legs can be stored. Similarly, the top plate 11b has edges 12b and 12b' on the two long sides of the top plate at an appropriate height so that the legs can be stored. Edges 12a' and 12b' are connected by a shaft 14. That is, the divided top plates 11a and 11b are connected by a shaft 14 and are formed so as to be foldable in two, and the legs 2 can be stored on the underside of the top plate.

[0011] Fig. 3 is a perspective view showing the leg section 2 when stored. The leg section 2 has four leg bodies 2a, 2b, 2c, and 2d that are long enough to fit inside the tabletop when stored, and an X-shaped reinforcing section 3. When assembled, it looks like Fig. 12. The X-shaped reinforcing portion 3 includes four L-shaped flexible wires 31a, 31b, 31c, and 31d. The L-shaped body 31a is composed of an upper side portion 311a and a lower leg portion 312a. Similarly, the L-shaped body 31b is composed of an upper side portion 311b and a lower leg portion 312b, the L-shaped body 31c is composed of an upper side portion 311c and a lower leg portion 312c, and the L-shaped body 31d is also composed of an upper side portion 311d and a lower leg portion 312d. The four L-shaped upper side portions 311a to 311d are rotatably connected to each other so as to intersect in an X shape at the center of the reinforcing portion. The material of the L-shaped body is preferably a springy material such as stainless steel, SW or SWP, but is not limited to this.

[0012] 4 to 7 are explanatory diagrams showing the procedure for removing the legs 2 from the table top 1 and assembling them.

[0013] In FIG. 4, the four legs 2a to 2d are rotated toward the outside of the reinforcing portion 3. Legs 2a and 2b can be rotated approximately 270 degrees to the left (as viewed in the figure) about the base ends of the legs. Legs 2c and 2d can be rotated approximately 270 degrees to the right (as viewed in the figure) about the base ends of the legs.

[0014] When the leg body 2a is rotated approximately 270 degrees in the outward direction, the lower foot portion 312a can be accommodated therein without colliding with the lower foot portion 312a. That is, the leg body 2a has an appropriate internal space capable of housing the lower foot portion 312a during use.

[0015] The legs 2a to 2d are an assembly type table having an appropriate internal space for storing the lower legs when in use.

[0016] The base end 21a of the leg 2a is rotatably connected to the lower foot portion 312a of the reinforcement part, and rotates around the base end 21a of the leg 2a toward the outside of the reinforcement part 3. When in use, the base end 21a of the leg 2a stands up so as to contact the ground and functions as a leg. The base end 21b of the leg 2b is rotatably connected to the lower foot portion 312b of the reinforcement portion, and rotates around the base end portion 21b of the leg 2b toward the outside of the reinforcement portion 3. When in use, the base end 21b of the leg 2b stands up so as to contact the ground and functions as a leg. Similarly, when the legs 2c and 2d are in use, the base end 21c of the leg 2c and the base end 21d of the leg 2d stand up in contact with the ground and function as legs.

[0017] In other words, the base ends of the four legs are each rotatably connected to the lower feet of the four L-shaped bodies, and when in use, the base ends of the four legs stand up so that they are in contact with the ground and function as legs.

[0018] FIG. 5 shows legs 2a and 2b in FIG. 4 rotated approximately 270 degrees to the left (as viewed in the figure) around their base ends, and legs 2c and 2d rotated approximately 270 degrees to the right (as viewed in the figure) around their base ends, in an upright position.

[0019] Fig. 6 shows a state in which legs 2a and 2b, and legs 2c and 2d, which were overlapping in Fig. 5, are spread apart. Base end 21a of leg 2a, base end 21b of leg 2b, base end 21c of leg 2c, and base end 21d of leg 2d stand up so as to be in contact with the ground, and legs 2a to 2d function as the four legs of a table.

[0020] The legs 2a to 2d are provided with claw portions 22a, 22b, 22c, and 22d at their respective tips, and the legs are provided with engaged portions 23a, 23b, 23c, and 23d.

[0021] 7, tabletop 1 has hole-like insertion portions 13a, 13b, 13c, and 13d near the vertices of the approximately rectangular tabletop. The insertion portions are elongated holes that are obliquely elongated from the center of the tabletop outward.

[0022] The legs 2a to 2d have claws 22a, 22b, 22c, and 22d at their respective tips, which are inserted into the insertion parts 13a, 13b, 13c, and 13d, respectively. In Fig. 8, the insertion parts 13a to 13d are arranged at positions that do not stand vertically when the legs are fixed to the tabletop, but are inclined toward the center of the tabletop. A gap is intentionally provided between the claws and the insertion parts.

[0023] FIG. 9 is a diagram showing the direction of tension applied when the legs are fixed to the tabletop.

[0024] As shown in Fig. 10, the distance from the bottom end of the claw of the leg to the top end of the engaged part is the same as the height of the edge 12a of the tabletop. In other words, the engaged part is positioned so that the distance from the bottom end of the claw to the top end of the engaged part is the same as the height of the edge of the tabletop.

[0025] The process of fixing the legs to the tabletop is as follows. (1) The claw portion 22a at the tip of the leg body 2a is inserted into the insertion portion 13a from the back side of the tabletop. (2) In FIG. 6, the leg 2a is tilted from the vertically standing position to the center of the tabletop as shown in FIG. 8. (3) The return portion 15a of the edge of the tabletop is engaged with the engaged portion 23a of the leg. The legs 2 a are fixed to the tabletop 1 .

[0026] The above steps (1) to (3) are carried out for the other three legs 2b to 2d in sequence. The order is not particularly important.

[0027] When leg body 2a changes from a vertically standing state to a state inclined toward the center of the tabletop as shown in Figure 8, elastic deformation (deflection) of reinforcing part 3, which is a flexible wire, applies tension to leg body 2a in the radial direction from the center of the tabletop toward the insertion part. Since the elastic deformation (deflection) of the flexible wire is utilized, it is preferable that the wire material have spring properties.

[0028] A gap is intentionally provided between the tab and the insert portion of the insert portion so that tension is not applied to the tab just by being inserted into the insert portion, but tension is applied to the engagement between the engaged portion 23a and the folded portion 15a at the edge of the tabletop shown in the above step (3).

[0029] As shown in FIG. 10, the engaged portions 23a, 23b are set to be at the same height as the shaft 14. If tension is not applied horizontally to the line connecting the shaft and the engaged part, the top plate will not be horizontal, as shown in Figure 11.

[0030] That is, in order to fix the legs to the tabletop, the tabletop has insertion portions near the four vertices and a return portion on the edge of the tabletop, and the legs have a claw portion and an engaged portion at each end, and each claw portion is inserted into each insertion portion, and the return portion engages with the engaged portion.

[0031] The insert portion is arranged so as to create a gap when the claw portion is inserted, and the engaged portion is positioned so that the distance from the lower end of the claw portion to the upper end of the engaged portion is the same as the height of the edge of the table top.

[0032] The leg reinforcement 3 is X-shaped, and objects can be placed on this part.

[0033] FIG. 12 is a perspective view showing the assembly table of the present invention in use. [Industrial Applicability]

[0034] The collapsible table of the present invention can be used in a variety of situations, such as camping, outdoor activities, events, and work sites. To provide a portable collapsible table that is lightweight and compact for storage, yet has a tabletop height above the ground suitable for use as a side table. A compact, portable table that can be carried in a backpack, yet has a tabletop height suitable for use as a side table, and achieves extremely practical stability.
