Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a system that can adjust the height arbitrarily according to the user's height.
This concerns how to adapt the height of desks, chairs, etc.

[Prior Art] Many school desks, chairs, and office chairs have telescopic supports and legs so that the height can be adjusted to the height of the user.

When changing the height of these devices, the user usually sits down and determines the height based on his/her experience.

However, in the case of school desks and chairs, the height is not determined solely by the feeling of sitting, but must be appropriately selected according to the individual height of the child or student, as this has a significant impact on the posture during use. It won't happen.

Conventionally, the method used in this case is to determine the height using numbers specified in JIS standards, numbers indicating the range of suitable heights, etc., but this method is based on the relationship between the body and the dimensions of the furniture. Unless you are a knowledgeable person or have a quick reference chart for compatibility, you will not be able to select the appropriate height, and even if you can obtain appropriate values for the height of your body and these desks and chairs. However, the height position, that is, the height of desks and chairs, must be determined by measuring each individual item, making the actual work extremely difficult.

[Problem to be solved by the invention 1 The present invention was developed in view of the above-mentioned drawbacks, and measures the user's height at m heights of desks and chairs that can be adjusted in height. A corresponding common display should be attached to both the height meter and the scale plate installed on the height adjustment part of the desk, chair support or leg, and the corresponding +1 scale when measured with the height meter and the desk. , by matching the height of the support or legs to the same scale plate attached to the scale plate of the chair, the height can be automatically set to match the height of the user. The purpose is to provide a method for adjusting the height of desks, chairs, etc.

[Means for Solving the Problems] That is, the present invention attaches a scale plate that displays the changing height to the adjustable part of the support or leg of a desk, chair, etc. that can adjust the height, and also A height meter is installed on a vertical wall or pillar, and the height meter displays a scale of multiple stages,
On the other hand said! The scale plate of the Ii1 node shows a multi-step scale corresponding to the scale of the height meter, and the corresponding scales on the scale plates of the height meter and the adjustment section have display means common to each other such as letters, numbers, colors, etc. When operating the height 7Jim of the desk, chair, etc., select the same scale display from the scale plate of the adjustment section as the scale that displays the height measured with the height meter, and adjust the height accordingly. To provide a method for adapting the height of a desk, chair, etc., characterized in that the height of the desk, chair, etc. is set to suit the user's height by fixing the height.

[Function] The adaptation method of the present invention is to attach the same indication as displayed on the height meter at the height position of desks and chairs that are determined to be optimal in advance for the user's height, and measure the height using the height meter. Find the same display as the one instructed on the scale plate provided on the support or leg adjustment part of the desk or chair, and operate the support or leg adjustment part in accordance with the result. It is possible to set the chair at an appropriate height, and the height suitable for each user's height can be set accurately and quickly.

[Example] Next, an example illustrating the method of the present invention will be described in detail below to clarify its characteristics.

Figure 1 shows the front view of the height meter, Figure 2 shows how the user's height is being measured by the height meter, and Figure 3 shows the height meter measuring the user's height.
5 through 5 are explanatory diagrams showing an example of the case where the present invention is applied to a school desk.

A height meter 1 for measuring the user's height is shaped like a vertically long plate, and on its surface there are scales 2a, 2b, 2c, 2d divided into constant lengths at equal intervals along the vertical direction. 2e is attached.

For scales 2a...2e, the length of one scale is 14cm here.
It is designed to display the total length of 70cm.
Each of the five scales has a different color; in this example, the highest scale 2a is blue, 2b is running green, 2c is yellow, 2d is orange,
It is color-coded with 2e being red.

This scale plate 1 is installed vertically along the vertical wall or pillar 3 of the classroom as shown in FIG. The upper edge of the top scale 2a is designed to represent 172c. On the other hand, the adjustment section 6 of the height-adjustable desk 5 is provided with a scale plate 7 displaying scales 7a...7e corresponding to the scales 2a...-2e of the height meter 1, respectively.

The desk 5 in this embodiment has a support 8 bent in the middle in a dogleg shape, and the upper subordinate pillar 8b is pivoted to the main support 8a standing vertically so that the bending angle can be changed freely. The tightening of the knob 9 provided at this pivot point changes the inclination angle of the subordinate support 8b by operation, so that the height of the top plate 10 can be changed.

As shown in FIG. 5, the main and subordinate support sections of the above-mentioned support columns have a large number of resistance plates 1 spaced apart from each other at their abutting ends.
1.12 is implanted, the resistance plates are inserted and engaged, and these are pivoted through a shaft 14 having a threaded portion 13 at one end, and by tightening the knob 9 screwed onto the threaded portion 13. Press the above resistance plates against each other and create a shaft! It has a structure that can restrain rotation about 4 as a fulcrum.

In the figure, numeral 15 is a pointer provided at the rotating end of the sub-support column 8b, and is designed to indicate the scale plate 7 attached to the upper end of the main column 8a.

By the way, the scale 7a of the scale plate 7 is the same as the scale 2 of the height meter 1.
The scale 7b corresponds to the scale 2b and is colored green, the scale @7c is yellow, the scale 7d is orange, and the scale 7e is red. colored.

The scales displayed on the 7JJm section 6 of this desk 5 are set to the most appropriate height for the user's height, and here 7a is for people over 158cm tall.

In addition, 7B is suitable for people with a height of 144cm to 158cm, and 7C is suitable for people with a height of 130cm to 144cm.
By aligning the pointer 15 with each scale, the height of the desk is set to match the height of the user.

Incidentally, as shown in FIG. 3, in this embodiment, when the height of the top plate 10 is changed by swinging the follower post 8b up and down by operating the knob 9, the top plate itself tilts back and forth accordingly. Therefore, here, the above-mentioned my
A connecting means 1B consisting of a large number of resistance plates 11 and 12 similar to that of section 6 is employed, and the inclination of the top plate can be adjusted by tightening the knob 9.

Therefore, based on the above configuration, assuming that the user has a 135C intestine, if this is measured based on the height scale 1, it will correspond to the yellow scale 2C, and based on this, next loosen the knob 9 of the desk 5. The pointer 15 provided at the rotating end of the sub-support post 8b is attached to the scale 7 with the same yellow color on the scale plate 7.
If the height is fixed by tightening the knob 9 in this state, the height will be automatically set to match the user's height. Similarly, when another user's height corresponds to the height calculation blue, if the pointer 15 pointing to the scale plate 7 of the desk is aligned with the blue scale 7a, the height of this user will automatically be 15.
This means that rArM can be set up on a desk at an appropriate height for people over 8c.

Next, Figures 6 and 7 show other examples in which the present invention is implemented on a chair whose height can be freely changed.

The chair shown here has a vertically erected cylindrical main leg 18a of a leg 18 supported by a support leg 17 extending in three directions, and a subordinate leg 18b, which is hung from the lower surface of the seat body 19 from above, is fitted into the main leg 18a. The screw 20 screwed into the main landing gear 18a is
By twisting the knob 21, the height can be fixed by biting the peripheral surface of the trailing leg 18b.
In the figure, 22 is a groove formed along the length direction on the circumferential surface of the follower leg 18b, 23a, 23. b, 23c, 23d,
23e is a scale arranged vertically along this groove to display the height.

24 is a reading window formed by cutting out the peripheral surface of the main leg 18a.

The scales 23a...23e are of the same kind as the scales displayed on the scale plate 7 of the desk 5, and the highest scale 23a is
The scales 23b, 23c, 23d, and 23e indicate the height suitable for people over 144cm and up to 158cm. These windows 2
By tightening the screws 20 according to height 4, the height can be set to suit the height of each individual.

Note that here as well, the scale 23 is similar to the scale plate 7.
Blue for a, green for 23b, yellow for 23c, 23d
23e is displayed in orange, and 23e is displayed in red.

When measuring the user's height with the height meter 1 in a chair configured in this manner, if the height corresponds to the blue color on the scale 2a, loosen the knob 21, align the blue color 23a with the window 24, and then tighten the knob again. If so, the height can be automatically set to match the height of the user.

[Effects of the Invention] As explained above, according to the present invention, the user's height is measured with a height meter attached to the wall, pillar, etc. of the classroom, and the same scale as the scale corresponding to this measurement is placed on the desk, chair style ff1i'f
Select from the i scale plate and adjust the height to match the selected scale.

It can automatically adjust to the optimal height,
At this time, there is an advantage that the height of the desk and chair can be easily set without the need to check the height of the desk or chair according to the height of each user, or to adjust the height while matching.

In addition, the method of the present invention allows even children to easily set the appropriate height by simply aligning the scale display confirmed by a height meter with the scale display on the adjustment section of the desk or chair. It is convenient as a height adjustment means of the same type.

In addition, it is convenient to display this scale by coloring the corresponding scales with the same color as explained in the above embodiment, and selecting the height by matching the colors. You will be able to work quickly.

Although colors are used in the examples to display the scales, this does not preclude the use of display means such as letters, numbers, patterns, etc., and the corresponding scales on the scale plates of the height meter and the adjustment section of the desk and chair. The present invention can be effectively implemented if both are displayed using the same display means.

In addition, although we have explained the case where the support for the desk is bent at the waist and the height of the top plate is changed depending on the rA angle, it is also possible to use a support that expands and contracts up and down and use the same display method as used for the chair above. Of course.
