Description

[Detailed explanation of the invention] [Industrial application field] The product of this invention can be used for meals, office use, reception use, table use,
It is used as a mounting platform and temporary storage for articles, and can be adapted to various uses by converting the height to three levels.

[Conventional technology]

Conventionally, desks for elementary and junior high school students have been known to be configured to be able to change the height stepwise or steplessly, but all of these desks are of the sliding type with a stopper mechanism. Ta.

[Problem that the invention attempts to solve]

In the conventional type, the structure of the slide mechanism inevitably makes the script body large, which is undesirable, and in terms of holding the stopper mechanism, it is difficult to withstand large loads, and the service life is also short. Moreover, the cost cannot be avoided.

[Means and actions for solving problems]

The present invention connects an upper rod and a lower rod of the same length, and connects the front part of the upper rod and the rear part of the lower rod through a bent part, and the length of the upper rod and the lower rod is longer than the length of the upper rod or the lower rod. a main leg member that connects the bent portions of the pair of main leg members and has a length longer than the diagonal rod and a diagonal rod connected at a length and an inclination angle such that the distance between the main leg members is shorter than that of the diagonal rod; a leg body composed of a long secondary leg member, and having the same length as the upper member or the lower member;
and a pair of grooves formed at the same interval as the length of the secondary leg member, a groove connecting one end of the pair of grooves, and a groove connecting the one ends at a position spaced apart from the groove by a certain distance. A top plate having a groove connecting the pair of grooves and a Z-shaped groove formed in the same shape as the main leg member on the back side. The height of the top plate is lowered, and the top plate is made higher when the patient is in a sideways position in the front-back direction, and it is made even higher than the above when the patient is in a sideways position in the left-right direction.In other words, the top plate can be changed to three levels of height. It is something.

[Example (1)] Figures 1 to 7 show the normal position. Figure 1 is a front view, Figure 2 is a top view, Figure 3 is a bottom view, Figure 4 is a side view, and Figure 4 is a side view. Figure 5 is a partially longitudinal side view showing the relationship between the legs and the top plate, and Figure 6 is the same as above.
The line sectional view and FIG. 7 are partially vertically sectional side views showing the relationship between the upper and lower rods and the legs, with A showing the legs and B showing the top plate.

Two leg bodies A are used, each of which consists of a main leg member A1 and a sub-leg member A2, and is made of a desired material, such as a light metal mainly made of aluminum, or reinforced plastic, into a pipe shape. The top plate B is made of the same material as the legs A, or ordinary plastic, or a wooden board, a laminated veneer board, or the like.

The main leg member A1 is formed of an upper rod 1, a lower rod 2, and a diagonal rod 4 in which the front part of the upper rod 1 and the rear part of the lower rod 2 are connected in series via a bent part 3, and the upper rod 1 and the rear part of the lower rod 2 are connected in series. The lengths of the upper rod 1 and the lower rod 2 are formed to be larger than the distance s from the lower rod 2.

Two secondary leg members A2 are used that are longer than the diagonal rods 4, and the left and right ends of these are connected to the main leg member A.
It is fixed to the opposing surfaces of the upper rods 1 and 1 and the lower rods 2 and 2 at the bent portion 3 of A1 and A1.
That is, they are fixed by well-known techniques such as welding means or the use of adhesives depending on the material used.

Note that 1a and 2a indicate rubber or other legs attached to the ends of the upper rod 1 and the lower rod 2, for example, by screwing means as shown in FIG.

Further, in the leg body A in this embodiment, the upper part thereof, that is, the upper rod indicated by reference numeral 1 in FIG. It is removably provided in a groove B1 formed on the back surface of plate B. In other words, it is simply fitted into the groove B1, and the fitted state is maintained by the load of the top plate B.

Note that FIG. 14 shows a groove B1 that is partially used in combination with other embodiments, and the portion indicated by reference numeral B1a in the same figure is the groove in this embodiment.

[Example (2)] Figures 8 to 10 show the case where the leg body A is tilted sideways by 90 degrees in the front and back direction from the normal position of the first embodiment, Figure 8 is a front view, and Figure 9 is a bottom view. , Figure 10 is a side view, showing A the leg body, A1 the main leg member, A2 the secondary leg member, 1 the upper rod, 2 the lower rod, 4 the diagonal rod, and B the top plate. .

The leg body A is formed in the same manner as that of the first embodiment, or in other words, the leg body A of the same embodiment can be used as it is, but the leg body A is formed in the same manner as that of the first embodiment. is performed at a location indicated by the reference numeral B1b in FIG.

[Example (3)] Figures 11 to 13 show the case where the leg body A is laid down 90 degrees in the left and right direction from the normal position of the first example.
Figure 1 is a front view, Figure 12 is a bottom view, and Figure 13 is a side view, where A is the leg, A1 is the main leg member, 1 is the upper lever, 2 is the lower lever, 4 is the diagonal lever, and B is the top board is shown.

The legs A are the same as those of the first embodiment, but fitting into the groove B1 of the top plate B is performed at a location indicated by the reference numeral B1c in FIG. 14.

[Example (4)] The sub-leg member A2 in this embodiment is fitted into the bent inner side of the bent portion 3 forming the main leg member A1, as shown in the side view of Fig. 15 and the plan view of Fig. 16. And it is done by welding.

[Example (5)] Legs 1a and 2a in this example are the first
As shown in FIG. 7, it is fitted into one end of the upper rod 1 and the lower rod 2.

[Example (6)] Although this example is not shown in the drawing, the top plate B
The upper rod 1 of the main leg member A1 constituting the leg body A
and the secondary leg member A2, or the secondary leg member A2 and the end of the upper rod 1, or only the main leg member A2, through a desired means (for example, each of the above parts directly or through a protrusion). ) is attached with screws. (The above three examples are
This corresponds to the cases of the first to third implementations. ) In the configuration described above, in the normal position, it is used as a low table as shown in Figures 1 and 4, and when the legs A are laid down 90 degrees in the front and back direction, it is used as a low table as shown in Figures 8 and 10. As shown in Fig. 11 and Fig. 13, when the table is used as a high table and the leg body A is tilted sideways by 90 degrees to the left and right, the 8th and 10th
It can be used as a higher table than the one shown in the figure or simply as a stand for articles, and if necessary, the lower part of the top plate B can be used for temporary storage of various articles.

Furthermore, Fig. 18 is a side view of the device of the present invention incorporating a heat generation function by electric heating and used for heating purposes, where A is the leg body, A1 is the left and right main leg members, 1 is the upper rod, and B is the leg body. indicates the top plate, and the opposing main leg members A1,
A heat generating housing 6 is attached to the lower part of the upper rods 1 and 1 of A1 via a heat insulating plate 5, a futon is covered, and a top plate B is placed on top.

[Effect of idea]

As mentioned above, the present invention allows the height of the top plate to be changed in three levels by simply tilting the legs horizontally at 90 degrees in the front-rear direction or left-right direction. When changing the orientation, a groove with the same shape as the part of the legs that comes into contact with the top plate is formed on the back of the top plate, so when the height of the top plate is changed, the legs and the top plate The positional relationship between the legs can be reliably fixed, and therefore, the top plate will not come off accidentally from the legs and can be used safely.
