JPH1165732A - Assistant stand for operation of keyboard - Google Patents

Abstract

PROBLEM TO BE SOLVED: To ensure a smooth operation of a keyboard and also to reduce the operating fatigue of a user by assembling a pair of arm support boards which can freely move along a guide part set in the width direction of the keyboard to a base board in a freely rotatable way. SOLUTION: A guide part 2 is added to a base board 1 in the width direction of a keyboard by means of a bottom member attached to the lower side of an upper member which are fixed together by screws. Then a pair of arm support boards 4 and 4 which can freely move along the part 2 are assembled to the board 1 in a freely rotatable way. In such a constitution, a key board operating assistant stand A is obtained. A window part 5 is prepared on the upper surface 1' of the board 1 for the part 2, and the leg members 6 of circular cross section shapes of both boards 4 are put into an inner void part 2a through the part 5 of the part 2. Then the fall-off preventing plates 7 are fixed at the free ends of the members 6. Thus, a user puts his both arms on the boards 4 and operates the keyboard. Under such conditions, the weight of arms are applied on the boards 4 and accordingly the boards 4 freely move within the part 2 in the weighted direction while being regulated by the part 5.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary table used when operating a keyboard operation of a personal computer, a word processor or the like.

[0002]

2. Description of the Related Art To operate a keyboard, it is common to lift both arms and hit a key with a fingertip.
If you operate the keyboard for a long time because your arms are lifted, fatigue accumulates and you cannot continue the keyboard operation for a long time.

[0003] In spite of such a problem with keyboard operation, at present, no measures have been taken to deal with this problem.

The present invention has been made in view of the above circumstances and aims to provide an article suitable for keyboard operation.

[0005]

A platform is provided with a guide portion along the width direction of the keyboard, and the pair of receiving plates for mounting the arm of the keyboard operator, which freely move along the guide portion, are provided. Basically, it is rotatably mounted on the base plate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of an auxiliary keyboard operation base according to the present invention; FIG.
A cross-sectional view of the line is shown.
Is a method in which a bottom member 1b is superimposed on a lower side of an upper member 1a in which substantially the entire area is recessed upward except for a peripheral end portion, and these members are fastened to each other with screws 3 to guide the keyboard along the width direction of the keyboard. A pair of receiving plates 4, 4, which freely move along the guide portions 2 of the base 1, are rotatably assembled to the base 1, and a keyboard operating auxiliary table A is provided. Is configured.

The guide portion 2 has a cross-section and has a groove shape, and has a window 5 provided by opening the upper surface 1 ′ of the base plate 1. The guide plate 2 is provided through the window 5 of the guide portion 2. 4 is inserted into the inner cavity 2a of the guide portion 2 at its free end (lower end) and has a circular shape (having a diameter larger than the width along the longitudinal direction of the window 5). The stopper plate 7 is fixed.

The receiving plate 4 has an elastic member 9 made of a foamed resin and a decorative sheet 10 covering the elastic member 9 superposed and fixed on the upper surface of a circular receiving member 8 having a protruding edge 8a at the peripheral end. Subject 8
Is provided with the leg members 6 and the retaining plate 7 on the lower surface side as described above.

When the keyboard operator places the left and right arms on the receiving plate 4 (the elastic member 9 serves as a cushion), and operates the keyboard, the load of the arm is applied on the receiving plate 4. Therefore, the receiving plate 4 can freely move in the guide portion 2 while being regulated by the window 5 according to the load direction (both vertical and horizontal directions in FIG. 1).
Go to

Incidentally, the retaining plate 7 and the bottom surface 2 'of the guide portion 2 are provided.
A material that minimizes contact resistance should be selected. In the embodiment, a synthetic resin is used.

[0011]

The present invention has the configuration described above,
Since the keyboard operation can be performed without any trouble by placing the arm on the receiver, the operation itself can be performed smoothly, and the accumulation of fatigue due to the operation can be reduced.
