Description

TECHNICAL FIELD The present invention relates to a portable winding table that can be wound and can be folded so as to be portable and convenient to carry.

Needless to say, the table is used for eating, reading, writing, or as a storage stand for ornaments, etc. However, when used indoors or outdoors, it should be designed to match the surrounding atmosphere. In addition, various selections are used in consideration of the user's taste and economic circumstances. However, depending on the intended use of the table, the table may not always be used at a fixed position.

As such a case, for example, there is a portable assembly table disclosed in Patent Document 1. Since this portable assembly table was invented on the assumption that it would be used outdoors, it adopts a configuration that allows it to be folded compactly and carried, and assembled and used on site. Specifically, a single table plate is assembled by spreading a foldable table structure plate flat with hinges and press-fitting a horizontal beam into a groove formed on the back surface of the plate, and furthermore, a bar material is attached to the horizontal beam. It is a table completed by crossing at the center and attaching rotatable legs. After use, each constituent member is removed, and then the table constituent plates constituting one table plate are rotated in opposite directions about hinges to form a hollow rectangular tube. Each constituent member is housed inside the hollow part of the body to provide a portable assembly table that is convenient for carrying and moving.

Japanese Patent Laid-Open No. 60-36011

According to the prior art disclosed in Patent Document 1, the table structure plate that constitutes the table plate is rotatably connected and fixed by a hinge. When finished, it can be folded into a hollow rectangular tube shape by rotating it to the opposite side around the hinge, and the rod-shaped members such as the legs can be compactly stored in the hollow portion for carrying. However, since hinges are used to rotate the table-constituting plate, the weight is increased, and screw nails or the like must be used for mounting, which causes a problem that production is troublesome. In addition, since the table plate and the legs are separate members, the number of parts increases, and mounting and dismantling work is required at the time of use and at the time of dismantling. There is a problem that it is troublesome to store it inside the hollow space of the body. In addition, since the legs are constructed by rotatably assembling rod members crosswise, it was necessary to reinforce the structure of the legs in order to place a heavy object on the table board. Furthermore, since there are long bolts or the like in the space below the table plate for connecting the two left and right cross-shaped legs, there is a problem that the space below cannot be effectively utilized.

means to solve

The present invention has been made in view of the above circumstances, and its means are as follows. That is, the top surfaces of a plurality of mounting surface members are coplanar and the surfaces of the plurality of leg surface members are coplanar, The legs are connected to each other so that the surfaces of the adjacent leg panels overlap each other, and at both ends of the mounting section, the individual placement panels and the individual leg panels are paired at right angles. The portable winding table is characterized in that the legs are bent at a right angle with respect to the placing portion by being connected so as to be freely bendable.

In addition, the mounting portion and the leg portions are formed by connecting and fixing the upper surfaces of the plurality of mounting surface members and the surfaces of the plurality of leg surface members with a flexible tape band so as to cross each of them.

Further, the individual mounting surface members and the individual leg surface members are individually connected by flexible tape strips.

Furthermore, the structure in which the leg portions are bent at right angles to the mounting portion is provided with a 45-degree inclined surface at each connection portion between the individual mounting surface members and the individual leg surface members. It is in.

Further, a magnet and a magnetized body are provided on the inclined surface of the connecting portion of the mounting surface member and the leg surface member.

In addition, the plurality of mounting surface members forming the mounting portion and the plurality of leg surface members forming the leg portions are biased in a direction in which they are brought into close contact with each other by a linear elastic member.

Also, the linear expansion and contraction members are inserted into through-holes formed inside the plurality of mounting surface members and leg surface members.

Further, the linear elastic member is an elastic rubber member.

Furthermore, the linear expansion/contraction member is a long coil spring.

In the portable take-up table of the present invention, a plurality of mounting surface members forming the mounting surface of the table are connected to each other in a bendable manner so that the top surfaces of adjacent mounting surface members overlap each other. are connected so that the surfaces of the adjacent leg panels overlap each other, so that when carrying it, it is rolled up and rolled up to reduce its bulk, so it can be put in a bag and shouldered when transported. It is easy and convenient to move by hanging it on a wall. When used as a table, the table can be obtained simply by bending a plurality of leg panels which are connected to both ends of the mounting portion so as to be freely bendable. is. Since each mounting surface member and each leg surface member are connected in pairs, the weight applied to the mounting portion is completely received by the vertical leg surface member, ensuring safety. Furthermore, since a space is formed under the placing section, it can be effectively used for things such as putting things therein.

Further, when the upper surfaces of the plurality of mounting surface members and the surfaces of the plurality of leg surface members are connected and fixed by flexible tape bands so as to traverse the respective surfaces, the mounting portion and the leg portions have a sense of unity. Mutually adjacent sides facilitate pivoting. Furthermore, the individual mounting surface members and the individual leg surface members are individually connected one-to-one by flexible tape bands, whereby the mounting portion and the leg portions are connected in a bendable manner. In addition to this, there is the advantage that the leg panels are rolled at the same time as the mounting panels are being rolled. Furthermore, since the connecting portions of the individual mounting surface members and the individual leg surface members are each provided with an inclined surface of 45 degrees, the mounting section can be easily bent at a right angle. The legs can easily receive the weight applied to the body, and the legs are less likely to rotate in the direction in which they open, thus ensuring safety. Furthermore, if the magnet and the metal to be magnetized are opposed to each other on the inclined surfaces facing each other, they are less likely to be separated from each other, which makes them easier to use and safer.

Further, if the plurality of mounting surface members constituting the mounting portion and the plurality of leg surface members constituting the leg portion are urged in a direction in which they are brought into close contact with each other by a linear elastic member, the mutually adjacent mounting surfaces can be arranged. This strengthens the close contact between the placing surface material and the leg surface material, and helps prevent peeling due to a change in the position angle when the top surfaces or surfaces of the placing surface material and the leg surface material are folded in the overlapping direction during winding. When the linear elastic member is an elastic rubber member, it can be manufactured at a low cost. When it is a long coil spring, it is durable and can be used for a long period of time. Furthermore, when the linear expandable member is inserted into the through holes formed inside the mounting surface member and the leg surface member, it is safe and does not break.

BEST MODE FOR CARRYING OUT THE INVENTION A best mode for carrying out the invention will be described with reference to the drawings. As shown in the assembled perspective view of FIG. 1, the portable take-up table 1 of the present invention comprises a mounting portion 2 comprising a plurality of mounting surface members 21, and both ends of the mounting portion 2. The main structural member is the leg portion 3 composed of the same number of leg members 31 as the mounting members 21 fixed rotatably. The mounting surface material 21 and the leg surface material 31 have a flat surface, a width of 4 to 10 cm, a thickness of 1 to 5 cm, and a length of about 30 to 100 cm for the mounting surface material 21 and about 10 to 50 cm for the leg surface material 31. Although a plate material within the range of is preferably used, it may exceed this range depending on the intended use, and is not particularly limited. In addition, the number of the mounting surface members 21 and the leg surface members 31 is not particularly limited, and may be appropriately selected according to the purpose of use. As the material of the plate material, wood, bamboo, natural resin, synthetic resin, light metal, etc. are appropriately selected and used according to the purpose of use.

As shown in FIGS. 1, 2 and 4, the plurality of mounting surface members 21 constituting the mounting portion 2 are arranged in close contact with each other in the longitudinal direction and flat in the horizontal direction. are connected and fixed by a flexible tape band 41 in a direction transverse to the upper surface 21a of the . The connection between the flexible tape strip 41 and each mounting surface member 21 may be by means of an adhesive, or by screwing depending on the material. Since people sit and articles are placed above the material 21, it is preferable that there is no projection. In this embodiment, as shown in the figure, three flexible tape strips 41 are attached and fixed so as to traverse the upper surfaces 21a of the respective mounting surfaces 21. 21 do not move in the horizontal direction, but are structured so that they can rotate about the flexible tape strip 41 located at the boundary position in the direction in which the upper surfaces 21a of the adjacent mounting surface members 21 overlap each other. The mounting surface material 21 can be wound from one end side to the other end side like a bamboo screen.

1, 2 and 4, the plurality of leg surface members 31 constituting the leg portion 3 are also flexible in the direction transverse to the surface 31a in the same manner as the mounting surface member 21. Although it is connected and fixed by the same means by the elastic tape band 42, since the length of the leg panel 31 is short in this embodiment, it is flexible across only one point on the end side adjacent to the mounting panel 21 side. Half of the width of the sex tape band 42 is fixed. The remaining half of the lateral width of the crossed flexible tape strip 42 is connected and fixed so as to cross the upper surface 21a of the mounting surface member 21 at the end of the mounting portion 2. A rotatable connection structure between the end portion and the leg panel 31 is constructed. Due to this connection and fixation, the surface 31a of the adjacent leg surface member 31 can rotate around the flexible tape band 42 located at the boundary in the direction in which the surfaces 31a of the adjacent leg members 31 overlap each other. is wound up, the leg surface material 31 is also wound up together. 1 and 2, the flexible tape band 42 is connected and fixed across both the mounting surface member 21 and the leg surface member 31, so that the connection and fixing portion is reinforced. Therefore, the connecting and fixing of the flexible tape band 42 is reinforced by the pin 5 having a head portion with a large pressing portion.

At both ends of the mounting portion 2, that is, both ends of the mounting surface member 21, there are formed inclined surfaces 21c which are inclined inwardly by 45 degrees from the upper surface 21a toward the lower surface 21b toward the lower surface. On the other hand, both ends of the mounting portion 2 are connected and fixed to the leg portions 3 by flexible tape bands 43, respectively, and the ends of the connecting side of the leg portions 3 extend from the front surface 31a side to the back surface 31b side. An inclined surface 31c inclined inward by 45 degrees is formed. As a result, the leg portion 3 can rotate 90 degrees with respect to the mounting portion 2, that is, at a right angle around the flexible tape band 42 located at the boundary between the mounting portion 2 and the leg portion 3. As shown in FIG. In order to reinforce the strength against the influence of the load applied to the mounting portion 2, the flexible tape band 42 serving as the rotation shaft has a leg surface member paired with each mounting surface member 21. Reinforcement flexible tape strips 43 are connected and fixed so as to straddle the inclined surfaces 31c of 31 separately.

As the material of the flexible tape strips 41, 42, 43, a thick sheet made of transparent synthetic resin can be suitably used. One that is integrally molded by inserting is preferable. Also, it is desirable that the inner surface is coated with a strong adhesive. In addition, animal leather, artificial leather, and the like may be used, and are not particularly limited.

In order to make the inclined portion 21c of the mounting surface member 21 and the inclined portion 31c of the leg surface member 31 strongly adhere to each other, a magnet 6 and a magnetizing body 7 magnetizing the magnet 6 are paired as needed. are provided on the corresponding inclined portions 21c and 31c. The number of pairs may be not all of the inclined portions 21c of the mounting surface member 21 and the inclined portions 31c of the leg surface member 31, but may be selected as appropriate depending on the magnetic force of the magnet 6 and the desired strength.

Although the plurality of mounting surface members 21 constituting the mounting portion 2 are connected and fixed by the flexible tape band 41, only the upper surface 21a on one side of the thick mounting surface member 21 can be connected and fixed. Therefore, when the upper surfaces 21a of the adjacent mounting surface members 21 are rolled in the direction in which they first overlap each other, the linear elastic member 8 is used to prevent the lower surfaces 21b from moving away from each other. . Suitable examples of the linear elastic member 8 include a rubber material and a long coil spring. This is to urge both ends of the mounting surface member 21 constituting the mounting portion 2 so as to attract each other. It is desirable to form a through hole 9 in the interior of the member 21 and to pass the linear elastic member 8 through the interior thereof and fix both ends thereof to the mounting surfaces 21 at both ends. If the mounting portion 2 is long, it is desirable to open two through holes 9 in the longitudinal direction as shown in the drawing. Similarly, for the leg portion 3, a through hole 9 is formed in the leg surface member 31 constituting the leg portion 3, and the linear elastic member 8 is passed through the through hole 9 and both ends thereof are fixed to the leg surface members 31 on both sides. It is desirable to keep

Next, an example of use of the portable winding table 1 of the present invention having the above configuration will be described. At the time of use, all that is required is to bend the leg portion 3, which consists of a plurality of leg panels 31 connected and fixed to both ends of the mounting portion 2 with flexible tape bands 41, at a right angle. At this time, if the magnet 6 and the magnetized body 7 are provided on the inclined portion 21c of the mounting surface member 21 and the inclined portion 31c of the leg surface member 31, the perpendicular angle to the mounting portion 2 is caused by these magnetizing forces. Stable and maintained regardless of the applied load. This table 1 can be used as a table for indoor use, as a table for outdoor use, or as a table for a wheelchair A as shown in FIG. 11, which is difficult to carry. In the case of this example of use, there is an advantage that the inner surface of the leg portion 3 hits the outer side of the handrail portion of the wheelchair A so that lateral movement is stopped and the wheelchair is stabilized.

By making the length of the leg surface material 31 which constitutes the leg part 3 variable, for example, when it is lengthened, it can be used as a table for reading or writing while standing. Further, by attaching a decorative cover to the lower part of the leg panel 31, the effect of the interior can be increased, or by attaching wheels, it can be applied to carry luggage or carry meal sets for sick people.

After use, the leg portion 3 is returned to the same position as the mounting portion 2 to form a flat surface as shown in FIG. 2 and the like. At this time, if the magnet 6 and the magnetized body 7 were used, it would be difficult to return, but if the tip of the leg portion 3 is held and rotated, it can be easily returned. Then, as shown in FIG. 9, from one end side of the mounting surface member 21, the upper surface 21a of the adjacent mounting surface member 21 is folded and wound to the other end side. At this time, the mounting surface material 21 rotates about the linear portion at the boundary position of the mounting surface material 21 as a rotation axis. It can be wound roughly round as shown. At this time, as shown in FIGS. 9 and 10, the linear elastic member 8 is stretched and exposed, so that the lower surface 21b side of the mounting surface member 21 is urged to bind inward. Since it has the effect of doing it, it is easy to round it up. After being wound in this manner, it can be placed in a cover bag 10 and carried over the shoulder if desired.

In the above description, the flexible tape strips 41, 42, and 43 are used to connect and fix a plurality of mounting surface members 21 to each other, to connect and fix a plurality of leg surface members 31 to each other, or to connect and fix the mounting surface members 21 together. Although the connection and fixation of the ends of the leg panels 31 has been described, hinges may be used in place of the flexible tape strips. In this case, since a large number of small hinges are required, the mounting work is troublesome. In addition, the overall weight is increased, but there is an advantage that the structure is strong.

Since this invention can be carried around by rolling up the table, it can be used for a variety of purposes as a portable device. I can expect it.
