Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to desk work and work, particularly in computer keyboard operation.
The present invention relates to an armrest on which an operator's elbow is placed and whose height is kept constant.

[0002]

2. Description of the Related Art It seems that there is no armrest that holds the elbow of a desk worker and keeps its height constant.
However, some chairs have armrests, but the armrests are for resting and are fixed, and they have an unnatural posture except for limited work, so you should not use them. Absent. That is, in most work, the worker is forced to keep his elbow lifted and kept at a constant height for a long time.

[0003]

A lot of desk work, especially keyboard operation of a computer, is a long work for keeping the elbow at a certain height while ensuring the freedom of horizontal movement of the hand. This work is carried out by holding the weight of the arm by lifting the shoulder, which causes stiffness in the shoulder. In addition, a stiff shoulder causes a headache, which causes the worker to suffer.

An object of the present invention is to provide an armrest capable of reducing fatigue of a desk worker.

[0005]

The universal armrest for desk work according to the present invention is rigid in the direction along the surface, is flexible in the direction perpendicular to the surface, and is vertically oriented in the width direction. As described above, the belt-like body has one end that can be mounted on a desk, and the elbow pad is supported at the other end of the belt-like body so that its height can be adjusted.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A support rod 1 having an adjustable length which can be fixed to a top plate end of a desk 4 with a vise 5, and a rigidity in a direction along a surface, which can be applied in a direction perpendicular to the surface. It is composed of a flexible strip 2 and an elbow pad 3, one end of the strip 2 is attached to the upper end of the support rod 1 in the width direction along the support rod 1, and the elbow pad 3 An armrest for desk work supported by height adjustable edges.

The strip 2 is composed of a plurality of plates 2a, 2b, 2
The armrest for desk work according to the above, in which c and 2d are connected to each other so as to be bendable by a rotary shaft 7.

An armrest for desk work as described in the above item 1 or 2, in which the armrest 3 is screwed to the other end of the strip 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a desk working armrest according to the present invention will be described with reference to FIGS.

This armrest is a support rod 1 whose length is adjustable.
A strip 2 having rigidity in the direction along the surface and flexibility in a direction perpendicular to the surface, and one end of which is rotatably attached to the upper end of the support rod 1, and It is composed of an elbow rest 3 supported at the other end so as to be adjustable in height.

A vise 5 is provided on the upper portion of the support rod 1 for attaching an armrest for working on the desk to an end portion of the top plate of the desk 4, and at a lower portion, a height adjustable for crimping to the floor. Screw 1a is screwed. The support rod 1 protects the top plate of the desk 4 from being damaged when a large force such as a part of body weight is applied to the elbow pad 3 in use.

The strip 2 is made up of a plurality of rigid metal plate bodies 2a, 2b, 2c, 2d which are bendably connected to each other.
It is installed so that it protrudes horizontally from the upper part of. At both ends in the longitudinal direction of each of the plate bodies 2a, 2b, 2c, 2d, there is formed a cylindrical portion into which the rotary shaft 6 is inserted when they are connected to each other. A female screw is formed on the cylindrical portion of the plate body 2d to which the elbow pad 3 is attached. The respective plate bodies 2a, 2b, 2c, 2d can be opened and closed by 180 degrees at their connecting portions. In the use state shown in FIG. 3 (1), each plate body 2a, 2b, 2c, 2d
Does not open beyond 180 degrees, it will not bend to the desk 4 side and come into contact with the desk 4 in the middle. The number of plates is
It can be increased or decreased according to the size of the desk 4 and the nature of the work. The strip 2 has rigidity in the direction along the surface,
As long as it is flexible in the direction perpendicular to the plane and can withstand the load of the arm or the like, there is no problem even if it is made of a single plate.

The elbow pad 3 has a built-in elastic padding (pad) so that it does not hurt even when working for a long time with the elbow rested, and the cylindrical portion of the plate 2d is seen from the back side. A threaded portion 3a that is screwed into the female screw of is projected. This screw part 3a
Due to the presence of, the height of the upper surface of the elbow pad 3 with respect to the belt-shaped body 2 can be adjusted to an ideal height suitable for work, and the elbow pad 3 is rotated in accordance with the left and right movements of the worker's hand. You can also

As for the armrests for desk work having such a structure, there are usually prepared two for the right elbow and one for the left elbow, and when each of them is used, the support rod 1 whose length has been adjusted is used by the vise 5 at the top to desk 4.
The belt-shaped body 2 is fixed to the top plate end of the so that the belt-shaped body 2 faces the front side. Then, the elbow pad 3 is rotated to adjust the height so that it is easy to work. If you put your elbow on the armrest 3 of the free-standing armrest set in this way and work on the keyboard of the computer, the height of the elbow is fixed and the shoulder is fixed even if the work takes a long time. Since the power of can be removed and the hand can move freely from side to side around the elbow, the burden on the shoulder is reduced, and fatigue is almost eliminated.

[0015]

Since the present invention is configured as described above, it has the following effects.

That is, since the elbow can be put on and the shoulder strength can be relaxed, it becomes possible to continue working on the desk for a long time without burdening the shoulder and prevent stiff shoulders, headaches and the like. be able to.
