Description

The present invention relates to a foldable table, and more particularly to a foldable table formed so that the space occupied by the legs when the top plate is folded can be narrowed.

Conventionally, as a table in which the top plate can be folded upright, there are, for example, those described in Patent Documents 1 and 2.

Since this type of conventional product can reduce the space occupied by the top plate during storage and transportation, it has an advantage that the space for storage and the like can be narrowed.

However, as seen in Patent Documents 1 and 2, this type of table has the lower part of the legs bent outward so that it can be stably supported when the top plate is spread horizontally, and when the top plate is folded. , The lower part of the leg is usually formed so as to be arranged in a C shape, for example, when viewed from above.

Therefore, in this type of conventional product, it is unavoidable that the lower part of the leg protrudes from the top plate when the top plate is folded. Therefore, since the space for storage and the packing size for transportation of the conventional product have increased, the number of storage and transportation cannot be increased by using the conventional product, and the cost of storage and transportation increases. There was a problem that it could not be done efficiently.

The present invention has been proposed in view of such problems of the conventional product.
Therefore, the technical problem to be solved by the present invention is that the top plate is formed so as to be foldable in an upright position, the lower portion of the leg supporting the top plate is bent, and the lower portion of the leg is the top plate. In a foldable table of the type that protrudes outward from the upright top plate when folded, space for storage and transportation can be prevented so that the lower part of the legs does not protrude from the top plate when the top plate is folded. It is an object of the present invention to provide a foldable table formed so as to enable the narrowing of the table, increase the number of storage and transportation, and reduce the cost of storage and transportation.

The present invention adopts the following technical means in order to solve the above problems.
That is, in the present invention, as shown in FIG. 1 and the like, the top plate 1 is formed so as to be vertically foldable, and the lower portion 2a of the leg 2 supporting the top plate 1 is formed when the top plate 1 is folded. A foldable table that is bent so as to protrude from the vertical top surface of the top plate 1, and the lower portion 2a of the leg 2 is attached to the straight upper portion 2b of the leg 2 and the upper portion thereof. It is characterized in that it is rotatably formed around the axis L of 2b and is stored and fixed in a gap S formed by the top plates 1 arranged back to back when the top plate 1 is folded (claimed). Item 1).

In the case of the present invention, the lower portion 2a of the leg 2 may be bent in a bent shape so as to be parallel to the ground contact surface (floor surface), and is not limited to the case where the leg 2 is curved. The shape of the top plate 1 is arbitrary, and may be designed to be a polygon such as a semicircle or a quadrangle, or a rhombus or an ellipse when connected. The legs 2 are usually formed of a cylindrical or square tubular metal pipe, but the material and the number of the legs 2 are arbitrary.

Further, in the table of the present invention, as shown in FIG. 4 and the like, holes 4 are formed in the upper portion 2b of the legs 2 at intervals in the circumferential direction of the legs 2, and the protrusions 5 are fitted into the holes 4. The manual operation unit 6 that fixes the lower portion 2a of the leg 2 to the upper portion 2b of the leg 2 constantly urges the protrusion 5 on the upper portion of the lower portion 2a of the leg 2 to the inside of the lower portion 2a of the leg 2. The manual operation unit 6 is formed so as to control the fitting state of the protrusion 5 and the hole 4 so that the lower portion 2a of the leg 2 can be rotated and fixed to the upper portion 2b. It is preferable to have (claim 2).

This is because, according to this, the lower portion 2a of the leg 2 can be fixed and released with one touch, which improves usability. Further, according to this, the leg 2 can be easily and quickly assembled without removing or reattaching the lower portion 2a of the leg 2 from the top plate 1.

Further, in the table of the present invention, as shown in FIG. 7, the hole 4 into which the protrusion 5 is fitted when the lower portion 2a of the leg 2 is stored has the axial center C of the hole 4 perpendicular to the top plate 1 when folded. It is preferably formed so as to match the diameter line d of the upper portion 2b of the leg 2 parallel to the surface (claim 3).

This is because, according to this, the lower portion 2a of the leg 2 can be neatly and neatly stored on the diameter line d described above.

In the present invention, the lower part of the leg is rotatably placed on the straight upper part of the leg around the axis of the upper part, and the top plates are arranged back to back when the top plate is folded. It is stored in the gap to be created and is formed so that it can be fixed.

Therefore, the present invention can prevent the lower portion of the leg from protruding from the top plate when the top plate is folded. Therefore, according to this, the lower part of the leg does not protrude from the top plate and narrow the space for storage and transportation.

As a result, according to this, the storage space and the packing size at the time of transportation can be reduced, and a large number of tables can be stored in a narrow space.

Further, in the conventional product, the lower part of the leg becomes an obstacle and it is difficult to stack, but according to the present invention, it is possible to stack and efficiently store and transport the product.
Therefore, according to this, in addition to being able to narrow the space when the top plate is folded upright, it is possible to increase the number of storage units and the number of transportation units, which in turn can reduce the storage cost and transportation cost. It has an excellent effect.

Hereinafter, a preferred embodiment for carrying out the present invention will be described with reference to the accompanying drawings.

In the table of the present invention, as shown in FIG. 1 and the like, the top plate 1 is formed so as to be vertically foldable. In this embodiment, the lower portion 2a of the leg 2 that supports the top plate 1 is curved so as to protrude from the vertical top surface of the top plate 1 when the top plate 1 is folded.

The top plate 1 is formed in a linear shape on the connecting side and an arc shape on the open end side so that when it is lifted and horizontally connected, it becomes an oval shape in this embodiment. Further, the top plate 1 is formed so as to be lockable when connected horizontally.

The legs 2 are formed of a metal round pipe in this embodiment, and the adjacent legs 2 on each top plate 1 are connected by a horizontal pipe 3 (see FIG. 2) along the floor surface. Further, the lower portion 2a of the leg 2 is rotatably formed on the straight upper portion 2b of the leg 2 about the axis L (see FIG. 1 and the like) of the upper portion 2b, and is back-to-back when the top plate 1 is folded. It is stored in the gap S formed by the arranged top plates 1 and is formed so as to be fixed.

In the case of this embodiment, as shown in FIG. 1, when the lower portion 2a of the leg 2 is rotated outward to be opened and protrudes from the vertical surface of the top plate 1 in the standing posture, the width D1 Is selected as 460 mm. Further, when the lower portion 2a of the leg 2 is rotated inward and stored in the gap S, the width D2 is selected to be 180 mm.

Further, in the present invention, holes 4 (see FIGS. 4, 5, 7, 7 and the like) are formed in a through shape in the upper portion 2b of the leg 2 at intervals in the circumferential direction of the leg 2. In the case of this embodiment, as shown in FIG. 7, the hole 4 into which the protrusion 5 is fitted when the lower portion 2a of the leg 2 is stored in the gap S has its axis C as the top plate 1 when folded. It is formed so as to match the diameter line d of the upper portion 2b of the leg 2 parallel to the vertical plane of the above. Further, in this embodiment, the hole 4 into which the protrusion 5 fits when the top plate 1 is lifted and horizontally connected and the lower portion 2a of the leg 2 is rotated outward and opened is the diameter line d described above. It is formed so as to be displaced in the circumferential direction of the leg 2 by about 45 degrees from.

Further, in the present invention, the manual operation unit 6 (see FIGS. 3 to 5 and the like) for fixing the lower portion 2a of the leg 2 to the upper portion 2b of the leg 2 by fitting the protrusion 5 into the hole 4 is the leg 2. It is provided on the upper part of the lower portion 2a. The diameter of the upper portion of the lower portion 2a of the leg 2 is enlarged. The manual operation unit 6 is arranged on the upper portion along the longitudinal direction of the leg 2 and is pivotally attached via the horizontal axis 7. The protrusion 5 is provided on the upper side of the manual operation portion 6 when the leg 2 is upright, and is always urged inward of the lower portion 2a of the leg 2 by the spring 8.

The product of the present invention is formed so that the above-mentioned manual operation portion 6 controls the fitting state of the protrusion 5 and the hole 4 so that the lower portion 2a of the leg 2 can be rotated and fixed to the upper portion 2b. It is something that is.

Specifically, in a state where the protrusion 5 is fitted into the hole 4 and the lower portion 2a of the leg 2 is fixed to the upper portion 2b (see FIG. 4A), the lower side of the manual operation portion 6 is the finger 9 (FIG. 4A). When pushed against the elastic force of the spring 8 by (see 4B), the upper side of the manual operation unit 6 rotates outward via the horizontal axis 7, whereby the protrusion 5 comes out of the hole 4 and is in the fitted state. Is formed to release. When the finger 9 is separated from the lower side of the manual operation portion 6, the upper side of the finger operation portion rotates inward by the restoring force of the spring 8, and the protrusion 5 engages with the hole 4 to engage with the lower side of the leg 2. The portion 2a is connected to the upper portion 2b.

In the table of the present invention, a caster 10 with a stopper is attached to the tip (lower end) of the lower portion 2a of the leg 2 so that the table can be easily moved.

Next, an example of using the product of the present invention of this embodiment will be described.

First, when storing, storing, or transporting the table, the user folds the top plate 1 and stores the lower portion 2a of the leg 2 in the gap S formed by the top plate 1.

Specifically, as shown in FIG. 4B, the user pushes the lower side of the manual operation unit 6 against the elastic force of the spring 8 with, for example, the thumb. Then, the upper side of the manual operation unit 6 rotates outward via the horizontal shaft 7, and the protrusion 5 comes out of the hole 4, whereby the locked state of the lower portion 2a of the leg 2 is released.

Next, the user uses the lower portion 2a of the leg 2 at 45 degrees or 135 in this embodiment, centering on the axis L (see FIGS. 1, 3, 4, 4, etc.) of the upper portion 2b of the leg 2. Turn it often (see Fig. 6). Then, the user releases his thumb from the lower side of the manual operation unit 6.

Then, the restoring force of the spring 8 causes the upper side of the manual operation portion 6 to rotate inward, and the diameter line d of the upper portion 2b of the leg 2 parallel to the vertical surface of the top plate 1 when the protrusion 5 is folded (FIG. 7). (See) is fitted into the hole 4 in which the axis C is aligned. As a result, the lower portion 2a of the leg 2 is fixed to the upper portion 2b of the leg 2.

When turning the lower portion 2a of the leg 2, the user releases the finger 9 from the lower side of the manual operation portion 6 and slides the tip of the protrusion 5 on the peripheral surface of the upper portion 2b of the leg 2. You can also do it at. In this case, when the protrusion 5 reaches the hole 4 at a position separated by 45 degrees or 135 degrees, the protrusion 5 is automatically pushed into the hole 4 by the action of the spring 8 and locked.

Therefore, when the manual operation unit 6 is formed as in this embodiment, the lower portion 2a of the leg 2 can be rotated and connected and fixed easily and quickly with one touch. .. When confirming the positions of the protrusion 5 and the hole 4, the leg 2 has a leg 2 as shown in FIG. 5 after the fitting state of the protrusion 5 and the hole 4 is released by using the manual operation unit 6. It is preferable to pull down the lower portion 2a so that the hole 4 can be visually recognized.

The product of the present invention is formed as described above. Therefore, as shown in FIG. 8, the lower portion 2a of the leg 2 fits in the gap S formed by the upright top plate 1 when the top plate 1 is folded, and does not protrude from the top plate 1.

Therefore, as shown in the figure, the products of the present invention need to be arranged close to the wall side at the time of storage, storage, or transportation, only requiring a small space corresponding to the folding width of the top plate 1. Can be done. As a result, according to this, a large number of tables can be efficiently stored and stored in a limited space. In addition, storage costs and transportation costs can be reduced accordingly.

In the above, in the case of the present invention, the rotation angle (rotation range) and rotation direction of the lower portion 2a of the leg 2 are not limited to the above example.

In the embodiment shown in FIGS. 9 and 10, the holes 4 are formed at intervals of, for example, 90 degrees in the circumferential direction of the upper portion 2b of the leg 2. That is, in the case of the present invention, the lower portion 2a of the leg 2 is, in short, expanded outward from the vertical surface of the top plate 1 when folded when used as a table, and is formed by the top plates 1 when stored. It suffices if the formation position of the hole 4 is selected so as to fit in the gap S.

Further, in the case of the present invention, the manual operation unit 6 may be formed as shown in FIGS. 11 and 12, and is not limited to the above example.

The manual operation unit 6 of this embodiment is passed to a metal U-shaped frame member 6a and opposed bending pieces 6b1 and 6b2 at both ends of the frame member 6a, and slides on the bending pieces 6b1 and 6b2. It is formed by including a round bar-shaped operating member 6c that is movably passed through, and a coil spring 6d that constantly repels the operating member 6c on one side along the longitudinal direction of the frame member 6a.

As shown in FIG. 12, the manual operation unit 6 is provided by, for example, welding a U-shaped frame member 6a to a pipe 3 connecting adjacent legs 2. In this embodiment, the operating member 6c is formed so that one end 6c1 is bent and one end 6c1 can be operated by hooking, for example, a finger. Further, the other end 6c2 of the operating member 6c is formed so as to be insertable into the hole 4 of the lower portion 2a via the through hole 11 of the upper portion 2b of the leg 2. The holes 4 are separately formed at positions shifted by a predetermined angle in the circumferential direction of the legs 2 as in the above example.

The coil spring 6d is externally attached to the operating member 6c and is arranged between the locking piece 6c3 fixed to the operating member 6c and one bending piece 6b1. The locking piece 6c3 is crimped to the other bent piece 6b2 by the elastic force of the coil spring 6d.

Next, the operation of the manual operation unit 6 of this embodiment will be described.
First, when storing the lower portion 2a of the leg 2, the user pulls one end 6c1 of the operating member 6c to the right side in FIG. 12 against the elastic force of the coil spring 6d, and the other end of the operating member 6c. 6c2 is pulled out from the hole 4 and the through hole 11 to release the connection and fixing state of the lower portion 2a and the upper portion 2b of the leg 2.

Next, the user turns the lower portion 2a of the leg 2 by a predetermined angle, and releases the finger from one end 6c1 of the operating member 6c when the hole 4 at the displaced position and the through hole 11 communicate with each other. Then, the coil spring 6d is restored, and the other end 6c2 of the operating member 6c is passed through the hole 4 and the through hole 11. As a result, the lower portion 2a of the leg 2 is connected and fixed to the upper portion 2b, and is stored in the gap S (see FIG. 1 and the like) formed by the top plate 1. When the lower portion 2a of the leg 2 is opened from the stored state, the manual operation unit 6 is operated as in the case of the stored state.

In this embodiment, the manual operation unit 6 is operated at the upper position of the joint 12 (see FIG. 12) between the lower portion 2a and the upper portion 2b of the leg 2, but the manual operation unit 6 is on the upper side. Similar to the example, it may be provided so that the lower portion 2a and the upper portion 2b can be connected and fixed at the lower position of the seam 12 and can be released from the connection.
