Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a table that can be used as a normal height table and a table by switching the height in two steps by a simple operation.
[0002]
[Prior art and problems to be solved]
As a table whose height can be adjusted, a table having extendable support legs, a table having foldable support legs, and the like are known.
[0003]
An object of the present invention is to propose a table capable of switching the height in two steps with a very simple configuration and a simple operation.
[0004]
[Means for Solving the Problems]
Referring to FIG. 1, the present invention relates to a table 1 having a top plate 2 and a pair of support legs 3 and 3 detachably attached to the top plate back surface 2a. First and second top plate support frames (short legs and long legs) 6 and 7 defining first and second top plate support surfaces 4 and 5 having different lengths orthogonal to each other, and these first And the connecting frame (center leg) 8 connected to each other in a state orthogonal to both the second top plate support frames 6 and 7 and the front end surface of the first top plate support frame 6 (tatami mat slide) ) 9 and the T-shaped second floor contact surface 12 defined by the side surface 11 of the connecting frame 8, the tip surface (tatami mat) 13 of the second top plate support frame 7, and another of the connecting frame 8 It has a T-shaped first floor contact surface 15 defined by the side surface 14.
[0005]
In the table 1 having this configuration, the length L6 of the first top plate support frame 6 is shorter than the length L7 of the second top plate support frame 7. Therefore, as shown in FIG. 1A, when each support leg 3 is erected so that the top plate 2 is supported by the first top plate support surface 4, the first floor contact surface 15 is placed on the floor. Is in a state of touching, and its height is increased to L7.
[0006]
On the other hand, as shown in FIG. 1B, when each support leg 3 is erected so that the top plate 2 is supported by the other second top plate support surface 5, the second floor The contact surface 12 is in contact with the floor, and its height is reduced to L6.
[0007]
Therefore, if the lengths L7 and L6 are set to appropriate dimensions, the table height can be switched between two levels: a normal table height and a table height. In addition, the height switching operation may be performed simply by changing the orientation of the support leg 3 by 90 degrees and changing the posture so that the side surface becomes the upper surface.
[0008]
In addition, the structure of the connection part of the top plate 2 and each support leg 3 may meet any structure. For example, it may be screwed or may have a structure in which a shallow groove for insertion is formed on the back surface of the top plate. Furthermore, the structure which only mounts on a support leg may be sufficient.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the table of the present invention will be described with reference to the drawings.
[0010]
2A and 2B are a perspective view showing a table and a perspective view showing support legs according to an embodiment of the present invention. The table 21 in this example also includes a rectangular top plate 22 and a pair of support legs 23 that support the rectangular top plate 22, and each support leg 23 has the same structure and is attached to and detached from the back surface of the top plate 22. Installed with possible mechanisms.
[0011]
The support leg 23 includes first and second top plate support frames 26 and 27 that define first and second top plate support surfaces 24 and 25 having different lengths orthogonal to each other, and the first and second top plate support frames 26 and 27. In a state orthogonal to both of the two top plate support frames 26 and 27, the connection frame 28 connected to each other, the tip surface 29 of the first top plate support frame 26, and the side surface 31 of the connection frame 28. A T-shaped first floor contact surface 32 defined, a tip surface 33 of the second top plate support frame 27 and another side surface 34 of the connecting frame 28 are defined. And a floor contact surface 35.
[0012]
The first top plate support frame 26 of the present example includes a pair of square members 36 and 37 extending in parallel, and three connecting members 38 and 39 that are connected in between and arranged in an orthogonal direction. 40. Similarly, the second top plate support frame 27 is also connected to a pair of square members 36 and 41 extending in parallel, and three connecting members 42 and 43 connected between them and arranged in an orthogonal direction. 44. The connection frame 28 has a shape in which the center of one rectangular plate is cut into a rectangle.
[0013]
In the table 21 of this example, the length L26 of the first top plate support frame 26 is shorter than the length L27 of the second top plate support frame 27. Therefore, as shown in FIG. 2, when each support leg 23 is erected so that the top plate 22 is supported by the first top plate support surface 24, the first floor contact surface 35 comes into contact with the floor. It becomes a state, and its height increases to L27.
[0014]
On the other hand, as shown in FIG. 3, when each support leg 23 is erected so that the top plate 22 is supported by the other second top plate support surface 25, the second floor contact surface 32. Is in contact with the floor, and its height is reduced to L26.
[0015]
Next, FIGS. 4A and 4B are perspective views showing another example of the support leg 23 described above. The support legs 53 shown in these drawings also have first and second top plate support frames 56 and 57 that define first and second top plate support surfaces 54 and 55 having different lengths orthogonal to each other. The connecting frame 58 connected to each of the first and second top plate support frames 56 and 57 in a state orthogonal to both the first top plate support frame 56 and the second top plate support frame 56, the front end surface 59 of the first top plate support frame 56 and the connection frame 58, a T-shaped second floor contact surface 62 defined by the side surface 61 of the 58, a T-shape defined by the distal end surface 63 of the second top plate support frame 57 and another side surface 64 of the connecting frame 58. And a first floor contact surface 65 having a shape.
[0016]
Here, the first and second top plate support frames 56 and 57 connect the two L-shaped square members 71 and 72 bent at a right angle to both ends of the L-shaped square members arranged in parallel, respectively. It is composed of connecting square members 73 and 74 and a connecting plate 75 that connects two L-shaped square members 71 and 72 to each other in the middle.
[0017]
Further, the connecting frame 58 includes one connecting square member 76 that is bent at a right angle and connected in a T shape to the two connecting square members 73 and 74.
[0018]
Also in the support frame 53 of this configuration, by changing the direction, it is possible to obtain a high support leg as shown in FIG. 4A and a low support leg as shown in FIG. 4B. The height of a top plate (not shown) supported by these can be switched between two steps of high and low.
[0019]
In each of the above examples, wood or plywood is used, but the support legs can be configured using metal plates or metal pipes. In addition, the support leg can be configured using a molded member made of a synthetic resin material. Furthermore, it is possible to configure the support legs using different materials.
[0020]
【The invention's effect】
As described above, according to the table of the present invention, the height can be changed in two steps only by a simple operation of changing the way of placing the support legs by 90 degrees.
