Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair having a table.

[0002]

2. Description of the Related Art For example, a chair with a table for infants is
It is disclosed in Japanese Patent Application Laid-Open No. 6-62935, Japanese Utility Model Publication No. 5-40758 and Japanese Utility Model Publication No. 4-2599.

The technique disclosed in the above publication aims to use the table provided on the chair at an appropriate height by raising and lowering the seat according to the growth degree of the infant.

[0004]

However, in the technique of the above publication, the table fixed to the chair is for a baby and is not removable, so that an adult cannot use the chair, There was a problem of poor versatility.

The present invention has been made to solve the above problems, and an object thereof is to provide a chair that can be used by infants to adults as a high chair and a low chair.

DETAILED DESCRIPTION OF THE INVENTION This embodiment will be described with reference to FIGS. As shown in FIG. 1, a pair of legs 2 and 3 are arranged so as to face each other, and the bases 2a and 3a that are wide in the front-rear direction are located below them.
Are formed. This chair is installed on the floor or the like of the stands 2a and 3a. Reinforcing plates 4 and 5 are fixed by bridges 22 between the stands 2a and 3a.

As shown in FIGS. 1 and 2, the backrest 6,
Reference numerals 7 and 8 are formed of curved plates, and are fixed between the legs 2 and 3 with screws 22 at predetermined vertical intervals.

The foot rest 11 is supported by fitting the groove 20 formed in the lower portion of the legs 2 and 3 with both ends of the foot rest 11 and is projected substantially horizontally from between the legs 2 and 3 to the front. . Then, the footrest 11 is fixed by the screw 22.

The seat portion 12 is supported by the groove 20 formed in the middle portion of the legs 2 and 3 and the side surface of the seat portion 12 being fitted and supported.
It is projected substantially horizontally from between the three. Further, the seat portion 12 is fixed by a fixing screw 23 having a knob.

The armrests 9 and 10 are supported by the protrusions 16 formed on the outer side surfaces thereof and the grooves 20 formed on the upper portions of the legs 2 and 3 being fitted to each other. Further, the armrests 9 and 10 are fixed to the legs 2 and 3 by fixing screws 23 having knobs.

The table 13 comprises a table body 13a and a pair of arms 18 and 19. Grooves 17 are formed on the inner surfaces of the arms 18 and 19, and the ridges 16 of the armrests 9 and 10 are fitted into the grooves 17. Arm 1 in this state
8 and 19 and armrests 9 and 10 are superposed. Furthermore, the arms 18, 19 are fixed to the armrests 9, 10 by a fixing screw 23 having a knob.

Since the arms 18 and 19 of the table 13 are overlapped with the armrests 9 and 10, the thickness of the armrest is substantially increased, the arm of the user can be stably supported, and it is easy to use. One end of the safety belt 21 is fixed to the center of the lower surface of the table 13. The U-shaped support fitting 24 is arranged at the front end of the lower surface of the seat 12 and the footrest 11. And
The other end of the safety belt 21 is a support fitting 24 on the lower surface of the seat portion 12.
It is stopped by the stopper 25. In this state, the infant can be prevented from falling from the chair by sitting on the seat 12 of the chair and passing the legs on both sides of the safety belt 21.

The table body 13a has a substantially rectangular shape, and ribs 13b are formed around the table body 13a to prevent the placed object from falling. Further, since the rear end portion of the table body 13a is concave, the table has a shape that makes it easy for an infant to eat.

When the infant sits on the seat 12 in this state, the infant can eat at the same height as the adult table. Then, the fixing screws 23 of the arms 18 and 19 are removed, the arms 18 and 19 are slid toward the front of the chair, and the table 13 can be removed by operating the knobs. In this way, by removing the table 13, it can be used as a high chair having the armrests 9 and 10 as shown in FIG. 4 from infants to adults.

Further, the armrests 9 and 10 can be easily removed by loosening and removing the fixing screws 23 for the armrests 9 and 10. The state is shown in FIG. And in this state, as a high chair without an armrest,
It can be used by infants to adults. Further, by using the footrest 11 and the seat portion 12, it can be used as a two-step step.

In addition, as shown in FIG. 6, if the seat portion 12 is removed and the armrests 9 and 10 are fixed by using the holes of the fixing screws 23 that have fixed the seat portion 12, the chair is placed on the table 13. And a low chair that uses the footrest 11 as a seat. In this case, the ridges 16 of the armrests 9 and 10 are fitted into the groove 20. Then, the safety belt 21 is stopped by the support fitting 24 of the footrest 11. In this case, the infant can use the table 13 at a low position to have a meal or the like.

Further, when the table 13 is removed, the chair becomes a low chair having armrests 9 and 10, as shown in FIG. 7, and can be used by infants to adults. in addition,
By removing the armrests 9 and 10 from the above state, the chair becomes a low chair that can be used by infants to adults as shown in FIG.

Further, since the knob of the fixing screw 23 is formed large, the fixing screw 23 can be easily attached and detached without using a tool such as a screwdriver. Therefore, the armrests 9 and 10, the table 13 and the seat portion 12 can be easily attached and detached.

Further, the height of the seat portion 12 can be easily changed in two steps by attaching or detaching the seat portion 12, and it can be used as a high chair and a low chair. In addition, since the height of the armrests 9 and 10 or the table 13 can be changed in two steps, it is very convenient. Therefore, the infant can use the table as a high chair and the table as a low chair. Furthermore, since a safety belt can be used as both a low chair and a high chair, an infant can be prevented from falling from the seat.

After the baby has grown up, the table 13 can be removed and used as a high chair and a low chair with armrests, and also as a high chair and a low chair without armrests.

Further, the ridges 16 of the armrests 9 and 10 are fitted into the grooves 20 of the legs 2 and 3 to exert the positioning function of the armrests 9 and 10 themselves and the positioning function of the arms 9 and 10 of the table 13. Exert.
