Abstract

(57) [Summary] [Problem] This invention can easily adjust the height of a seat, a footrest, and a backboard, and can independently adjust the height between a seat and a footrest, or between a seat and a backboard. The aim is to develop and provide a vertically movable chair that can be used by anyone from children to adults. As a means for solving this problem, the present invention makes it easy to adjust the height of a seat, a footrest, and a back plate, and
Each part is screwed so that it can be done independently, and the height of the seat, footrest and backboard can be arbitrarily moved at predetermined intervals so that anyone from children to adults can use it.

Description

[Detailed description of the invention]     [0001]   [Technical field to which the invention belongs]   According to this invention, the seat, the leg rest, and the back plate are fixed with locking members such as screws and nuts. A vertically movable chair that can be freely moved at predetermined intervals independently in the vertical direction It is.     [0002]   [Prior art]   When adjusting the vertical height of a conventional wooden learning chair, etc., the height of the seat Alternatively, the seat and the back plate are integrally formed and the height of the integrated structure is changed.     [0003]   Therefore, especially in the case of chairs for students, etc. There was a situation where I had to buy a new chair.     [0004]   In addition, since height, sitting height, body shape, etc. are different for each individual, in the case of an integrated chair The current situation is that it is difficult to find anything that fits your body .     [0005]   [Problems to be solved by the invention]   Therefore, this invention makes it possible to easily adjust the height of the seat, footrest, and back plate, and The height between the footrest (L1) and the height between the seat and the backboard (L2) can be adjusted independently. The aim is to develop and provide a vertically movable chair that can be used by anyone from children to adults.     [0006]   [Means for Solving the Problems]   As a means to solve this problem, this invention is to adjust the height of seats, footrests and backboards. Each part is screwed down so that it can be easily and independently performed. The height of the seat / footrest / backboard can be moved at predetermined intervals so that anyone can use it. It was to so.     [0007]   [Embodiment of the invention]   Therefore, one embodiment of the present invention will be described in detail with reference to FIGS. , And the leg rest (2) are provided with a plurality of mounting holes (4a) (4b) at predetermined intervals (P). A chair that can be moved upward and downward on the gantry (4) having the gantry (4) And a back plate (3) is fixed to the connecting plate (5), and An adjusting plate (6) having a plurality of mounting holes (4b) is provided at predetermined intervals (P). The height of the back plate (3) is provided so as to be adjustable along the adjustment plate (6).     [0008]   First, when each component is described in detail, the shape of the seat (1) is substantially square or rectangular. And a seat frame (1c) is formed around it, and urethane rubber is formed on the upper portion of the seat frame (1c). Provided with an elastic member (1b '), such as collagen leather (1b), etc. And a long hole (1a ') is provided on both left and right side surfaces which can be adjusted to move forward and backward. A screw hole (1a) for screw fixing is provided in the center of the rear part of the seat frame (1c).     [0009]   Next, the footrest (2) is made of a wooden board and the front side is formed into an R shape in consideration of safety. It has a rectangular shape, and screw holes (2a) for screwing are provided on both left and right S) is fixed.     [0010]   Also, the backboard (3) is made by bending a wooden board slightly into an R shape according to the human back. When the back is addressed to the back plate, consideration is given so that there is no discomfort, and a rectangular A wooden board (3b) is attached, and screw holes (3a) for screwing are provided at two places in the center. (S).     [0011]   The mount (4) is made of wood, and the base (4 ') of the chair, the left and right sides of the seat, and the middle of the rear. The center is fixed with locking members such as screws (S) and nuts (N), and at predetermined intervals (P) It is formed by providing a plurality of freely movable mounting holes (4a) and (4b).     [0012]   An adjustment hole (4c) is provided at the center of the rectangular plate connecting the left and right sides of the gantry (4). It is designed so that the screw can be removed even when the chair is lowered.     [0013]   Further, FIG. 3 shows an assembly procedure diagram of each of the above components. ), The footrest (2) and the back plate (3), and remove the locking members for mounting. And fixed with a locking member such as a screw (S) and a nut (N).     [0014]   Next, the height adjustment range of each part is shown. First, the height of the seat is 340 to 520 mm. In five steps, the height of the backboard part is five steps of 800 to 624 mm, and the height of the footrest part is It can be adjusted in three stages of 130, 190, and 250 mm. It is possible to support a wide range according to the height of the tabletop of the desk from 590 to 730mm Noh.     [0015]   [Effect of the invention]   The idea is that the seat, the footrest and the backboard of the chair are screwed and independent. By providing a plurality of mounting holes to allow arbitrary movement in the vertical direction, Height adjustment is possible, and a wide range of use is possible from children to adults.     [0016]   Also, since the seat part, footrest part and back plate part are screwed independently, between the seat and the back plate And the dimensional adjustment between the seat and the leg rest can be adjusted independently, so a wider range of fine adjustment is possible Being able to use it has a very beneficial effect, such as the ability to use it according to the purpose or application. To play.     [0017]   Furthermore, since the structure is simple, anyone can handle and a chair that fits the user's body Can be provided.
