DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a chair having armrests.

[0002]

2. Description of the Related Art Conventionally, in a chair provided with a chair body and an armrest provided on the chair body, an armrest constituting the armrest is vertically moved so that an upper end portion is located forward of a lower end portion. There is known an elbow rod which is slidable up and down along an inclination direction of the elbow rod.

[0003]

However, in the case of the above-mentioned armrest, the weight of the armrest and the load of the elbow and the like are received by one oblique rod which is obliquely inclined. The properties were poor or the strength of the elbow rod had to be increased. For this reason, depending on the material of the elbow rod, the weight is greatly increased, and accordingly, it is necessary to connect the armrest and the chair body by complicated connecting means, or the weight of the entire chair is increased. I was

[0004] Further, since the elbow pad is slid by one elbow rod, the elbow pad may be slid during the sliding of the elbow pad, so that there is a lack of certainty in the operation of the elbow pad. .

More specifically, the elbow rest moves back and forth at the same time as the sliding operation up and down, but cannot be moved in the left-right width direction. Elbows that change position could not be supported properly.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides an elbow pad provided with a plurality of parallel elbows inclined with respect to a vertical direction along the inclination direction of the elbow. By supporting the armrest so that it can move up and down, the stability and operation smoothness of the armrest can be improved, and the armrest can be set to a position that is easy to use according to the sitting posture and physique of the user. It was done.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, a chair according to the present invention comprises a chair body and an armrest provided on the chair body, wherein the armrest is provided with an armrest on which an elbow can be placed, and a vertical armrest. A plurality of parallel elbow rods that are inclined with respect to each other are provided, and these elbow rods support the elbow pad so as to be able to move up and down along the inclination direction.

With such a structure, the weight of the armrest and the load of the elbow and the like can be dispersed and supported by the plurality of elbow rods. As a result, the stability of the elbow rest during use can be improved, and the user can be given a suitable feeling of use.

Further, since a relatively light material can be used for each of the elbow rods, the weight of the entire chair can be reduced. Conversely, the strength of the armrest can be increased without increasing the weight of the entire chair.

[0010] Further, the elbow rest is provided by a plurality of elbow rods.
These elbow rods can be moved up and down along the direction of inclination, making it harder to squeeze and not only improve the reliability of operation smoothness, but also adjust the height and match the sitting posture and physique of the user Thus, the elbow pad can be set at a position that is easy to use.

[0011] In the operation of OA equipment, which is increasing in offices and the like, particularly when operating a keyboard or the like on a desk, a seated person sitting in a chair works with his arms extended forward. In order to reduce the burden on the arm by appropriately supporting the elbow, which moves forward while rotating upward around the shoulder, the elbow rod must have an upper end at the lower end. It is desirable that it is inclined with respect to the vertical direction so as to be located further forward.

Particularly when a person with a large physique sits on a chair, the elbow, which is positioned relatively outside and above the person with a small physique, is suitably supported, and the position adjustment of the elbow rest according to the physique is realized. In order to do so, it is desirable that the elbow rod is inclined with respect to the vertical direction such that the upper end is located outside the lower end in the left-right width direction.

As a specific embodiment, an elbow rod is attached to a chair body, and a guide member provided on the elbow pad is supported by the elbow rod so as to be vertically movable. .

[0014]

An embodiment of the present invention will be described below with reference to the drawings.

A chair 10 shown in FIG. 1 comprises a chair body 2 and a pair of armrests 3 attached to both sides of the chair body 2.

The chair body 2 has a seat 23 supported at the upper end of a column 22 standing upright from the center of the leg blade 21.
The backrest 24 is attached to the rear of the backrest 24 so that the backrest 24 can perform a locking operation by an appropriate mechanism.

The armrest 3 has an armrest 31 on which an elbow can be placed, and a support 4 having a lower end fixed to a seat and supporting the armrest 31.

The elbow pad 31 is composed of a pedestal 32 having a substantially rectangular shape which is long in front and rear, and a pad 33 made of a cushion material attached so as to cover the upper surface of the pedestal 32. .

The support 4 is interposed between two parallel elbow rods 41 inclined with respect to the vertical direction such that the upper end is located forward of the lower end, and between the elbow rest 31 and the elbow rod 41. And a cylindrical guide member 42.

The elbow rods 41 have a columnar shape and are spaced apart from each other so as to be lined up and down. Then, these elbow rods 41 are connected so that the lower ends of the elbow rods 41 are connected to each other.
And a plate-shaped mounting member 5 is integrally provided with the mounting member 5, and the mounting member 5 is fixed to the side back surface of a seat receiver 25 constituting the seat 23.

The guide member 42 includes a pair of front and rear tubular bodies 43 having upper ends fixed to the center of the lower surface of the elbow pad 31, and a connecting plate for connecting the upper ends of the tubular bodies 43 and the lower ends thereof. 44, and a through hole 45 penetrating left and right is formed in the center portion thereof. The cylindrical body 43 is a round pipe having an inner peripheral surface forming a guide hole 46, and the inner peripheral shape substantially matches the outer peripheral shape of the elbow rod 41. The guide member 42 is provided with the elbow rod 41 in these guide holes 46.
Are inserted from below, and are fitted to the elbow rod 41 so as to be slidable up and down as shown in a sectional view in FIG. The guide member 46 does not cover the elbow rod 41 from outside as described above, but may be configured to cover the guide member 46 from the outside.

Thus, the elbow rod 41 and the guide member 4
As shown in FIG. 2, the elbow pad 31 moves up and down, and at the same time, moves back and forth. The operation of the armrest 3 will be specifically described below.

First, when the armrest 31 is pulled up or down, the upper end is fixed to the armrest 31 and the guide member 42 has the same inclination angle as the elbow rod 41.
Is guided by the elbow rod 41 and smoothly slides up and down. At this time, the elbow pad 31 and the guide member 42 slide up and down while maintaining the same posture. As a result, the elbow pad 31 moves back and forth at the same time as it moves up and down.

Therefore, according to the present embodiment, the elbow rest 3
The weight such as 1 and the load such as the elbow can be dispersed and supported by the two elbow rods 41. As a result, the stability of the armrest 31 during use can be improved, so that the user can be given a suitable feeling of use.

Further, since a relatively light material can be used for the elbow rod 41, the weight of the entire chair 10 can be reduced. Conversely, the strength of the armrest 3 can be increased without increasing the weight of the entire chair 10.

Furthermore, since the direction in which the elbow rod 41 is inclined and the direction in which the tubular bodies 43 are aligned are made coincident, the guide member 42 can be slid up and down along the elbow rod 41. It is easy to improve structural strength and operation smoothness. Also, since the elbow pad 41 is raised and positioned forward at the same time, when a seated person positions his arm forward in operation of a keyboard on a desk, etc., the armrest 41 is raised and positioned forward. Elbow that will be, the elbow rest 31 is set to a suitable position,
Be able to support.

In addition, since the guide member covers the elbow rod 41 from the outside and is located above the elbow rod 41, the exposure of the elbow rod 41 is suppressed as much as possible to improve the appearance. Can be.

The specific configuration of each section is not limited to the above-described embodiment. For example, as a modified example, as shown in FIGS. 4, 5 and 6, the armrest 31 constituting the armrest 3 is vertically moved so that the upper end is located outside the lower end in the left-right width direction. An example in which two parallel elbow rods 41 that are inclined with respect to each other and that are supported so as to be slidable up and down along the inclination direction of the elbow rod 41 can be given. In this case, the elbow pad 31 moves in the left-right width direction at the same time as the up-and-down movement by the elbow rods 41. Therefore, when a person with a large physique sits on the chair 10, the elbow rest 31 is relatively outer than a person with a small physique. The elbow to be positioned above can be suitably supported, and the position adjustment of the elbow pad 31 according to the physique can be easily realized with a simple configuration.

Also, the elbow pad is inclined by two parallel elbow rods which are inclined with respect to the vertical direction so that the upper end is located forward of the lower end and outward in the width direction. One that is slidably supported up and down along the direction can be cited. In this case, the armrests move up and down and right and left at the same time as they move up and down by these elbow rods, so it is possible to adjust the position of the armrests according to the physique with a simple configuration, and work with the arms extended. It becomes possible to set the position of the elbow rest corresponding to the keyboard operation or the like to be performed.

More specifically, the elbow rest is moved along the inclination direction of the elbow rod by two parallel elbow rods which are inclined with respect to the vertical direction so that the upper end is located behind the lower end. And those supported to be slidable up and down. In this case, these elbow rods raise the elbow rest at the same time as it moves up and back, so if you are leaning back and leaning comfortably in a comfortable position, you should be located relatively behind the work position. Can be suitably supported, and a comfortable resting posture can be provided by sitting.

Further, the elbow pad is moved up and down along the inclination direction of the elbow rod by a single elbow rod inclined with respect to the vertical direction so that the upper end is located outside the lower end in the width direction. One that can be movably supported can also be mentioned.
Also in this case, since the elbow rest moves in the left-right width direction at the same time as moving up and down, the position adjustment of the elbow rest according to the physique can be easily realized with a simple configuration.

[0032] In addition, the guide member is made to stand up from each side of the chair body, and the elbow rod is provided directly on the lower surface of the armrest, and the elbow rod is slid up and down on the fixed guide member. One that is movably fitted can be cited. As described above, the guide members and the upper and lower positions of the elbow rods which are reversed from those in the above embodiment also support the elbow rests so as to be able to move up and down along the inclination direction thereof, as described above. The same effect can be achieved.

Furthermore, the inner peripheral shape of the guide hole may be an oval so that the two elbow rods can be fitted together.

Further, the cross-sectional shape of the elbow rod is not limited, such as a prism, and in this case, the guide hole is formed to have an inner peripheral shape capable of fitting the elbow rod. If so, the above-described effects can be obtained.

Instead of moving the elbow rest up and down by guiding the elbow rest by the guide member as in the present embodiment, the elbow rest may be moved up and down by using another structure. Furthermore, the number of elbow rods, the shape of the armrests, and the like are not limited to the above-described embodiment.

Other configurations can be variously modified without departing from the present invention.
