Description

{portable prefabricated table}

The present invention relates to a portable, modular table that is lightweight and compact and has a tabletop height above ground suitable for use as a side table.

Existing camping tables have been used as portable, modular tables, and many products have stability and lightness by lowering the table top height to about 100 mm. These tables can be stored in a backpack, which increases portability. However, the seat height of the lightweight chair used with these tables is set to about 300 to 400 mm, so when you stretch out your hand to use the table while sitting, there is a problem of poor operability on tables with a table top height of about 100 mm. This is especially noticeable when assuming use as a side table. For use as a side table, the table top height from the ground is preferably about 300 mm.

Therefore, there is a demand for the development of a table that has a shape that can be carried with a lightweight and compact chair, while also ensuring sufficient stability and having a table top height suitable for use as a side table. It is thought that a table that combines all of these elements will contribute to improved convenience and operability.

The assembly table of Patent Document 1 is a lightweight, compact, and portable assembly table, but because the height of the top plate above the ground is low, it is not easy to operate as a side table.

In addition, the camping folding table of Patent Document 2 has short legs that fold and are stored inside the back of the table top, and a connecting leg for the short legs, so that the legs are raised and can be 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, a portable, modular table that can be stored compactly and lightweight, and has a table top height above the ground suitable for use as a side table has been demanded.

Fig. 1 is a perspective view showing the assembled table of the present invention when stored. The top plate (1) is foldable, and the top plate (1) is provided with a divided top plate (11a) and a top plate (11b).

A leg part (2) is stored on the back side of the top plate (1). It is preferable to perform a punching process on the top plate (1) to make it lightweight. In addition, the material of the top plate is preferably aluminum, but is not limited thereto.

Fig. 2 is a perspective view showing the assembled table when the top plate is opened for storage. The top plate (11a) has edge portions (12a, 12a') of an appropriate height for storing legs on two long sides of the top plate. Similarly, the top plate (11b) has edge portions (12b, 12b') of an appropriate height for storing legs on two long sides of the top plate. The edge portions (12a') and the edge portions (12b') are connected by a shaft (14).

That is, the divided top plate (11a) and top plate (11b) are formed to be foldable by being connected by an axis (14), and a leg part (2) can be stored on the back surface of the top plate.

Figure 3 is a perspective view showing the leg part (2) when stored. The leg part (2) is equipped with three leg bodies (2a, 2b, 2c, 2d) of a length that matches the top plate when stored and an X-shaped reinforcing part (3). When assembled, it becomes as shown in Figure 12.

The above X-shaped reinforcing member (3) has four L-shaped flexible wires (31a, 31b, 31c, 31d). The L-member (31a) is composed of an upper edge portion (311a) and a lower edge portion (312a). Similarly, the L-member (31b) is composed of an upper edge portion (311b) and a lower edge portion (312b), the L-member (31c) is composed of an upper edge portion (311c) and a lower edge portion (312c), and the L-member (31d) is also composed of an upper edge portion (311d) and a lower edge portion (312d).

The above four L-shaped upper edges (311a to 311d) are rotatably connected to intersect in an X shape at the center of the reinforcement part.

The material of L itself is preferably elastic, such as stainless steel, SW or SWP, but is not limited thereto.

Figures 4 to 7 are explanatory drawings showing the procedure for removing the legs (2) from the top plate (1) and assembling them.

In Fig. 4, four leg bodies (2a to 2d) are rotated in the outward direction of the reinforcing part (3).

The leg body (2a, 2b) can rotate about 270 degrees in the left direction (in the drawing) around the base of the leg body.

The leg bodies (2c and 2d) can rotate about 270 degrees in the right direction (in the drawing) around the base of the leg body.

When the above leg body (2a) rotates 270 degrees in the outward direction, it can accommodate the lower leg part (312a) inside without colliding with the lower leg part (312a).

That is, the leg body (2a) has an appropriate internal space capable of storing the lower leg (312a) when in use.

The above leg body (2a to 2d) is an assembly table characterized by having an appropriate internal space capable of storing the lower leg portion when in use.

The leg body (2a) is rotatably connected to the lower leg (312a) of the reinforcement part at the base (21a) of the leg body (2a), and rotates in the outward direction of the reinforcement part (3) with the base (21a) of the leg body (2a) as the center. When in use, the base (21a) of the leg body (2a) is erected so that it is in contact with the ground and functions as a leg.

The leg body (2b) is rotatably connected to the lower foot plate (312b) of the reinforcement part at the base part (21b) of the leg body (2b), and rotates in the outward direction of the reinforcement part (3) around the base part (21b) of the leg body (2b). When in use, the base part (21b) of the leg body (2b) is erected so that it touches the ground and functions as a leg.

Likewise, the leg body (2c) and the leg body (2d) are erected so that the base part (21c) of the leg body (2c) and the base part (21d) of the leg body (2d) are in contact with the ground when in use, thereby functioning as legs.

That is, it is an assembly table characterized in that the base parts of the four leg bodies are rotatably connected to the four L-shaped lower legs, and when in use, the base parts of the four leg bodies are erected so as to touch the ground and function as legs.

FIG. 5 is a standing state in which the leg bodies (2a, 2b) of FIG. 4 are rotated about 270 degrees in the left direction (in the drawing) about the leg body base part as the center, and the leg bodies (2c, 2d) are rotated about 270 degrees in the right direction (in the drawing) about the leg body base part as the center.

Fig. 6 shows the leg bodies (2a, 2b, 2c, 2d) that were overlapped in Fig. 5 in an open state. It shows that the four parts of the base part (21a) of the leg body (2a), the base part (21b) of the leg body (2b), the base part (21c) of the leg body (2c), and the base part (21d) of the leg body (2d) are standing up so that they are in contact with the ground, thereby indicating that the leg bodies 2a-2d function as four legs of a table.

In addition, the leg bodies (2a to 2d) are provided with catches (22a, 22b, 22c, 22d) at each tip. In addition, the leg bodies are provided with connecting parts (23a, 23b, 23c, 23d).

In Fig. 7, the top plate includes hole-shaped inserts (13a, 13b, 13c, 13d) near the corners of the roughly rectangular top plate. The inserts are rectangular holes that are inclined outwardly from the center of the top plate.

The above leg bodies (2a to 2d) are provided with catches (22a, 22b, 22c, 22d) at their respective ends, and are inserted into the insertion portions (13a, 13b, 13c, 13d), respectively. In Fig. 8, the insertion portions (13a to 13d) are not positioned vertically when the leg bodies are fixed to the upper plate, but are positioned so as to be inclined toward the center of the upper plate. A gap is intentionally provided between the catches and the insertion portions.

Figure 9 is a drawing showing the direction of tension applied when fixing the leg body to the top plate.

As shown in Fig. 10, the distance from the lower end of the catch projection of the leg body to the upper end of the engagement portion is equal to the height of the upper plate edge portion (12a). That is, the engagement portion is positioned so that the distance from the lower end of the catch projection to the upper end of the engagement portion is equal to the height of the upper plate edge portion.

The process of attaching the bridge body to the top plate is as follows.

(1) Insert the catch (22a) of the tip of the above leg body (2a) into the insertion part (13a) from the back of the top plate.

(2) In Fig. 6, the leg body (2a) is made to be tilted toward the center of the top plate as shown in the figure while being erected vertically.

(3) Attach the upper plate edge inversion part (15a) to the connecting part (23a) of the leg body.

The leg body (2a) is fixed to the top plate (1).

The above processes (1) to (2) are performed sequentially for the other three leg bodies (2b to 2d). The order is not particularly strict.

When the leg body (2a) is tilted toward the center of the top plate as shown in the figure from a vertically erected state, tension is applied radially from the center of the top plate toward the insertion part to the leg body (2a) due to elastic deformation (sagging) of the flexible reinforcing member (3).

Since it utilizes the elastic deformation (sagging) of the flexible wire, it is desirable that the wire material be elastic.

The above-mentioned catch is intentionally spaced between the catch and the insertion portion. This is to ensure that tension is not applied simply by inserting the catch into the insertion portion, but rather to ensure that tension is applied to the connection between the joined portion (23a) shown in (3) of the above-mentioned process and the inverted portion (15a) of the edge of the upper plate.

As shown in Fig. 10, the above-mentioned connecting portions (23a, 23b) are made to have the same height as the shaft (14).

If tension is not applied in the horizontal direction of the line connecting the shaft and the connecting member, the top plate will not be horizontal, as shown in Fig. 11.

That is, in order to fix the leg body to the top plate, the top plate has insertion portions near two vertices and an inversion portion at an edge of the top plate, the leg body has a catch and a connecting portion at each end, and each of the catch projections is inserted into each of the insertion portions, and the inversion portion and the connecting portion are connected.

In addition, the insertion portion is provided so that a gap is created when the catch is inserted, and the engaging portion is positioned so that the distance from the lower portion of the catch to the upper portion of the engaging portion and the height of the edge of the top plate are the same.

The reinforcement part (3) of the leg is shaped like an X, so objects can be placed on this part.

Figure 12 is a perspective view showing an assembly table when the present invention is in use.

The assembly table of the present invention can be used in various fields such as camping, outdoor activities, events, and work sites.

A portable, modular table is provided that is lightweight and compact to store, yet has a tabletop height suitable for use as a side table. It has a small and compact storage form that can be carried as a backpack, yet has a tabletop height suitable for use as a side table, thus realizing practical stability.
