Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple table that can be placed on a thigh and used for meals or various office work or used as a data table.
[0002]
[Prior art]
In vehicles such as aircraft and bullet trains, the table provided behind the front seat is used in the foreground, or the table stored in the armrest of the seat is taken out and used. It is. A chair used in a public facility such as a school may be accompanied by a table that can be raised inward and fixed approximately horizontally.
[0003]
[Problems to be solved by the invention]
But it's better to have a table like this, and if it doesn't, it's hard. For example, in a traveling car, it is said that a lunch is placed on the thigh and eats, but if the thigh is inclined forward or backward while sitting on the seat, it will not be horizontal Also, it is hard to eat because the position is also low. Similarly, it is inconvenient when reading and writing.
[0004]
Accordingly, it is an object of the present invention to provide a simple table for use on the thigh so as to solve the above-described problems and obtain a substantially horizontal surface. .
[0005]
[Means and Actions for Solving the Problems]
The above object is a table portion, a leg portion provided on the left right sides composed of a receiving portion of the passed thigh suspended between the legs of the left and right sides, front and rear receiving portion of the thigh pair of Ri belt-shaped body der, and wherein the adjustment mechanism of at least one side of the belt-shaped body with by the length of which is provided, it is a simple table placed on the thigh Is achieved.
[0006]
The simple table of the present invention is installed such that the belt-like body contacts the thigh. Since this belt-like body can be flexibly deformed, it can be deformed into a shape along both sides and the upper surface of the thigh, and can be deformed to absorb the inclination of the thigh. Thus, the table portion can be kept in a substantially horizontal posture.
[0007]
By the way, in the prior art mentioned above, since such a table is certainly attached, a table can be used as needed. However, since such a table is located at an average height and is not adapted to the individual body size, there is a problem that it is difficult to use. In other words, because the height is made constant, for example, it can be adjusted to the seat height for a wide variety of body shapes that range from 140 cm female height to 185 cm male height. Absent.
[0008]
Therefore, it is desirable that the simple table of the present invention can obtain a horizontal surface having a height suitable for the individual body size.
[0009]
So In this invention, those receiving portion of the thigh Ri pair of belt-shaped body der before and after the and at least one side of the belt-shaped body with by the length of the adjustment mechanism of which is provided It is .
[0010]
If the thigh receiving part is just a pair of front and rear belt-like bodies, the table part cannot take a horizontal posture unless the thigh is horizontal. Therefore, by loosening the tension of the belt-like body on the upper side in the direction in which the thigh is inclined, the table portion on that side can be lowered. You can have a horizontal posture. Furthermore, the height of the entire table portion can be changed by adjusting the tension of each of the pair of front and rear belt-like bodies. For example, it is preferable to lower the arm and bend the elbow to adjust the position of the table portion to the height of the horizontal position.
[0011]
In addition, although it is preferable that a table part is horizontal at the time of a meal, it may be preferable to incline so that the near side may become low at the time of reading and writing. In such a case, it is only necessary to loosen the tension of the belt-like body on the near side, and the present invention can cope with such an object well. Therefore, it is possible to set the inclination state of the user's preference for any purpose.
[0016]
Next, in the first aspect of the present invention, the table portion is formed of a sheet-like body, and the left and right leg portions are crossed in an X shape on the front and rear sides, and are provided so as to be rotatable with respect to each other. The left and right leg portions have stoppers for fixing the opening angle of the left and right leg portions while the sheet-like body is stretched between the leg portions. It can be provided between them.
[0017]
At the time of storage and transportation, the crossed state of the legs can be folded to be compact. In use, the leg portions are opened, and the leg portions are fixed with a stopper when the sheet-like body is tight. This operation can make this simple table usable.
[0018]
In the present invention, the material of the table portion can be selected arbitrarily, and wood, plastic, etc. can be used freely. In the case of using a sheet-like body as in the invention of claim 2 , cloth, leather, a plastic sheet or the like can be arbitrarily employed for the sheet state. The belt-like body of the thigh receiving part is preferably a non-slip cloth belt, but the material can be freely selected even if attached to this belt. As for the legs, metal parts are better for folding, and square and round pipes made of plastic extrusion can be used for detachable parts. Is possible. The design of the table part is not particularly limited.
[0019]
DETAILED DESCRIPTION OF THE INVENTION

[0020]
First Embodiment Referring to FIGS. 1 to 3, this embodiment will be described. Leg portions 2 are provided at four corners of a bottom surface portion of a substantially square synthetic resin table plate 1, and each of the left and right pairs is provided. Is formed by a belt 3 serving as a thigh receiving part (FIG. 1). The table plate 1 is formed by connecting two plates with a hinge 10 so that the table plate 1 can be folded in the middle, and a slide shaft 13 for locking the table plate 1 in an unfolded state, and this A pair with a shaft receiving portion 14 for allowing the slide shaft 13 to pass therethrough is attached to opposite sides of the side surface portion of the table plate 1 sandwiching the two-folded portion. A circular groove 11 for placing a cup is provided on one side of the table plate 1 (FIG. 2).
[0021]
Further, as shown in FIG. 3, the leg portion 2 is composed of a substantially square Ω-shaped metal round bar as a whole, and the leg portion is formed in the shaft hole 22 opened in both side walls of the storage portion 21. The rotating shaft 20 part which is the both ends of the part 2 is inserted. It should be noted that the rotating shaft 20 portion is always urged outward by utilizing the spring property of the leg 2 and does not come out of the shaft hole 22 even if a force is applied in a direction opposite to this force. Designed to. Further, the edge portions 24 of both side wall portions of the storage portion 21 are bent inward, and a notch groove 23 is formed in a portion corresponding to the shaft hole 22. Such storage portions 21 are fixed to the four corners of the bottom surface portion of the table plate 1. Therefore, while the leg 2 is raised, the leg 2 is fitted in the notch groove 23 to maintain this state. However, by applying force to the leg 2 from both sides and applying force in the direction of tilting, the leg 2 2 can be folded inward and stored under the edge 24.
[0022]
Next, the belt 3 is a leather-made flexible one that is turned around the tip of the leg 2 (FIG. 3). Further, a buckle 30 for adjusting the length is attached to the belt 3 (FIG. 2).

Now, as described above, when the leg 2 is folded, the table plate 1 can be folded in two and can be carried and stored compactly (FIG. 2). Next, to use this, the table plate 1 is opened and the slide shaft 13 is inserted through the shaft receiving portion 14 to lock the open state, and the four leg portions 2 are raised together. Therefore, when the belt 3 is placed on the thigh as shown in FIG. 1, the belt 3 can be flexibly deformed, so that the table plate 1 can be maintained in a substantially horizontal posture. . If it is desired to increase the height of the table plate 1, the buckle 30 is adjusted to shorten the length of the two pairs of belts 3. Further, it is possible to make the table plate 1 horizontal and adjust the inclination angle.
[0024]
In the above-described configuration, the pair of belts 3 are stretched between the leg portions 2 so as to straddle the folded portion of the table plate 1, but the direction is such that it does not straddle the folded portion. It is possible to omit the pair of the slide shaft 13 and the shaft receiving portion 14 so as to span between the leg portions 2. This is because the force for folding the table plate 1 in half can be diverted.
[0025]
Second Embodiment The configuration of the simple table of this embodiment largely follows the configuration of the first embodiment described above, but is characterized in that the mounting positions of the legs 2 are different. In other words, it is characterized in that when the table plate 1 is folded in half, the storage portion 21 and the leg portion 2 are attached with their positions shifted so as not to overlap (FIG. 4). In addition, the attachment position of the accommodating part and leg part drawn with the broken line is a thing of the above-mentioned 1st Embodiment.
[0026]
With this configuration, the storage portion 21 and the leg portion 2 do not overlap when the table plate 1 is folded, so that the overall thickness of the folded table plate 1 can be reduced and further compacted. I can do it.
[0027]
Third Embodiment The configuration of the simple table of this embodiment largely follows the configuration of the first embodiment described above, but the configuration of attaching the leg portion 4 to the table plate 1 is different. That is, the leg portions 4 made of synthetic resin having a cubic shape can be inserted into and removed from the fitting grooves 42 of the receiving portions 41 provided at the four corners of the table plate 1. A belt through hole 40 is formed in the vicinity of the tip of the leg 4 to stop the belt 3 (FIG. 5).
[0028]
In the case of the simple table of this embodiment, when used, the leg portion 4 with the belt 3 is fitted into the fitting grooves 42 of the receiving portions 41 provided at the four corners of the table plate 1. Further, the leg portion 4 is removed from the receiving portion 41 when folded. The leg portion 4 and the belt 3 are integrally removed. It is also preferable to provide a storage portion for the leg portion 4 on the back surface of the table plate 1.
[0029]
Fourth Embodiment Next, a fourth embodiment of the present invention will be described with reference to FIG. This simple table adopts a conventional folding chair structure, and can be folded compactly and can be used speedily.
[0030]
