Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a chair that is convenient for changing the posture of facing a desk, stand, etc.

(Prior Art) Conventional chairs for doing office work or work while facing a desk or stand are designed so that the main body of the chair is held only in a substantially horizontal position, so that the seated person is not allowed to lean forward or lean forward. There was a problem in that it was not possible to respond immediately when you wanted to maintain a backward leaning posture.

(Problem to be solved by the invention) The present invention solves the above-mentioned problems of the conventional chair and allows the chair to easily take a forward-backward posture suitable for office work or work, or a backward-leaning posture suitable for rest, in addition to the normal state. It was completed with the purpose of making a chair that could be used for walking.

(Means for Solving the Problems) In the present invention, front casters and rear casters for horizontally holding the chair main body are provided on the horizontal frame members respectively installed between the lower ends of the front and rear legs of the chair main body, and Each front end of the frame member is provided with auxiliary casters for supporting the chair main body in a forward leaning state, and each rear end of the horizontal frame member is provided with a support portion for supporting the chair main body in a backward leaning state. That is.

(Example) Next, the illustrated embodiment will be described in detail.

1 is mainly a chair made of metal pipe material,
Front casters 2 and rear casters 3 for holding the chair main body 1 horizontally are provided on the horizontal frame members 1a, 1a, which are respectively installed between the lower ends of the front and rear legs of the chair main body 1. Further, the horizontal frame member 1a,
Auxiliary casters 4 for supporting the chair main body 1 in a forward leaning state are provided at each front end of the horizontal frame members 1a, and support portions 5 for supporting the chair main body 1 in a backward leaning state are provided at each rear end of the horizontal frame members 1a, 1a. has been established.

In this structure, horizontal frame members 1 are installed between the lower ends of both the front and rear legs of the chair main body 1.
The front casters 2 and rear casters 3 provided on a and 1a, respectively, hold the chair main body 1 horizontally so that it can be used in the same way as a conventional chair. When performing office work or work in a forward-leaning posture suitable for this, the seated person can move their hips slightly toward the front of the seat to move the center of gravity forward, as shown in Figure 2. is tilted forward and the forward tilted state is immediately adjusted by the front casters 2, 2 and the auxiliary casters 4, 4 provided at the front ends of the horizontal frame members 1a, 1a to support the chair main body 1 in the forward tilted state. In this case, since the front casters 2, 2 and the auxiliary casters 4, 4 are wheels that can freely change direction, the operation can be carried out smoothly. Next, as shown in FIG. 3, if the seated person's center of gravity is moved to the rear by moving the waist to the rear of the seat, the main body of the chair 1 is tilted backward, and the rear casters 3, 3 and the horizontal frame member 1a , 1a, which support the chair main body 1 in the backwardly tilted state, the seat can immediately maintain the backwardly tilted state, and the seated person can rest. You can easily assume a suitable comfortable position, but
This backward tilted state is always stably maintained by the support portions 5, 5 preventing the chair main body 1 from freely retreating due to the rolling of the rear casters 3, 3.

(Effects of the invention) As is clear from the explanation of the above embodiments, the present invention allows a seated person to hold the main body of the chair horizontally and use it in the same way as a conventional chair; If you want to do office work or work in a forward-leaning position, or if you want to take a backward-leaning position suitable for rest, simply move your hips slightly to tilt the chair into a forward-leaning or backward-leaning position that is suitable for each case. It can be easily and stably maintained, has a simple structure, and can be provided at low cost, and together with this, it has extremely great practical value.
