Description

Assist armrest for chair {ASSISTANCE ARMREST FOR CHAIR}

The present invention relates to an auxiliary armrest for a chair, and more particularly, to an auxiliary armrest provided to support an arm portion in front of a user's body while being folded and installed on an armrest provided in a chair.

Universal armrest provided in the chair is provided on both sides of the backrest and the seat plate constituting the chair to maintain a comfortable posture by placing the arm in the user sitting state.

As described above, the armrest is developed and used in various types of chairs, and a representative armrest for the prior art is shown in FIG. 6.

The armrest 1 is connected between the front of both sides of the seat plate 4 at the intermediate position of the backrest 3 constituting the chair 2, it is composed of an integral bar type protruding forward from the backrest 3 or The armrest body 5 is supported by the supporter protruding upward from both sides of the frame supporting the seat plate 4.

The upper surface of the armrest body 5 is further provided with a pad (6) having a cushion function to increase the feeling of use while preventing impact or damage when contacted with the user's arm.

Since the armrest for a chair to which the prior art as described above is applied is located at both sides of the seat plate, the user can sit the forearm between the elbows and the elbows while sitting.

For this reason, when the forearm is to be placed on the armrest, the forearm portion must be artificially positioned on the armrest while sitting on a chair, so the forearm cannot be supported in the working state.

In other words, if you want to sit at the desk of the home or office, or to use the work or computer for learning or work, it is impossible to use the armrest mounted on the arm rest provided in the chair.

This is because when the user wants to use a computer, the elbow or forearm naturally escapes the armrest because the arm protrudes in the direction of the keyboard while the chair is placed on the end of the desk.

In particular, since the elbows or forearms are located in the air between the end of the desk and the chair, considerable fatigue is transmitted because they try to keep the arm almost horizontal in the process of using the keyboard.

As such, when fatigue is transmitted to the arm, it causes muscle stiffness, which affects not only the arm muscles but also the shoulder muscles, which causes physical problems such as stiff shoulders.

Accordingly, the present invention further includes an auxiliary arm rest that can support the forearm in a pulled out state by combining the hinge to the side of the arm rest provided in the conventional chair as the invention to solve the above problems. ,

When sitting at a desk, the forearm can be supported in a stable state without being located in the air, thereby reducing the fatigue of the user and achieving the purpose of performing efficient work.

The present invention is to simply be folded to prevent exposure when sitting, and to support the forearm to be placed in the air in a stable state when drawn out when performing tasks such as using a computer so that the user's arms and shoulders are not unreasonable It is an invention having various effects such as to alleviate fatigue.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

It demonstrates together as a block diagram of the cross-sectional state of the applied auxiliary armrest for chairs.

The arm is provided on both side edges of the seat plate 101 located at the upper side of the frame constituting the chair 100 and the backrest 102 located at the rear of the seat plate 101 so that the user's arm can be mounted. Rest 103.

In the present invention, the armrest 103 is further provided with an auxiliary armrest 105 to move in and out as needed, particularly between the desk and the chair to stably support the arm placed in the air to reduce fatigue while reducing the user's convenience. Characterized in that to increase the.

In the present invention, the auxiliary arm rest 105 is coupled to the hinge 106 on the side of the arm rest 103 provided in the chair 100 to rotate forward to the user's selection to maintain the drawn state do.

The auxiliary arm rest 105 may be positioned above or below the arm rest 103 or may be accommodated and drawn out through an accommodation groove formed separately in the arm rest 103.

It is preferable that the upper surface of the auxiliary arm rest 105 is provided with a pad 107 of a material having a cushioning property so as to increase the feeling of use when contacting the forearm, and to maintain the stored state below the armrest 103. A stopper may be further provided.

Auxiliary arm rest 105 for a chair of the present invention as described above,

When the user simply remains seated on the chair 100, the user does not use the auxiliary armrest 105 to store it under the armrest 103 so as not to be exposed so as not to interfere with the behavior or cause interference. do.

And, when a work such as using a computer is required, the auxiliary arm rest 105, which was stored below the arm rest 103, is taken out and placed in front of the user's chest.

That is, the auxiliary arm rest 105 is located between the chair and the desk so that the user stably supports the forearm when using the keyboard to use the computer so that the user does not become floating in the air, thereby reducing physical damage or fatigue of the user. It will be comfortable to use.

As another example of the auxiliary arm rest 105, the hinge 109 is fixed to the upper end of the post 108 protruding upward from both sides of the seat plate 101 from the frame constituting the chair 100 to the chair 100. In a seated state, it may be configured to rotate in the direction of the backrest 102 and to rotate forward when used.

The present invention as described above is an invention having a variety of advantages, such as to receive and withdraw the armrest by the user's selection to keep the arm comfortable to reduce the physical fatigue in the process of operation to increase the efficiency of the operation.
