Abstract

PURPOSE: A safety chair is provided, which prevents a user from being hurt by preventing a wheel chair from being moved backward. CONSTITUTION: A safety chair comprises: a central rod(130) in which a brake pad is adhered closely to the floor side by the weight when being seated on a chair; a housing in which a ring and spring of the central rod are mounted so that the central rod can have restitution force while moving to the top and bottom; and a brake pad(150) which restricts the movement of the chair when the weight is applied to the chair.

Description

Safety chair {Safety chair}

The present invention relates to a safety chair, and more particularly, to prevent children and elderly people from being injured in a chair, one of which is slipped from a wheeled chair and is prevented from being broken in an accident such as a snare or asshole. It's about a chair.

In general, a chair widely used in a company, a house, a school, an academy, or the like is a chair support part consisting of a simple backrest and a floor support, and a handle capable of mounting a user's arm on both sides of the chair support, and a plurality of wheels capable of moving. It consists of a leg or a leg consisting of a plurality of legs.

The chair support may be integrally formed with the backrest and the bottom rest or separately formed. In particular, the backrest and the bottom rest has a beautiful curved product formed integrally with the chair support is configured to bend to provide comfort as well as to correct the user's posture.

The conventional chair as described above has been spreading and providing a comfortable posture to users, but celery men and students who work for a long time are stressed due to problems such as a slow blood circulation due to their long working hours. In order to solve the problem of chronic fatigue such as feeling fatigue, the release of functional chairs is increasing.

There are many accidents that occur in the conventional wheeled chairs, safety accidents are falling off the chair, but it does not solve the fundamental problem of the chair to turn to the fault of the child, or turn to the responsibility of their own mistakes.

The problem to be solved by the present invention is that when the children sit on the wheeled chair, the legs do not reach, so when the upper body is moved forward, the center of gravity is in the rear direction, so the wheeled chair is pushed backwards and the children are squeezed or hurt their chin. The purpose is to provide a safety chair to prevent cases from occurring.

Another object of the present invention is to provide a safety chair that can be fixed in place when sitting or waking up in the office and home.

The problem solving means of the present invention is a wheeled chair,

A central rod consisting of a spring and a ring for fixing the spring to the bottom of the chair such that the brake pad is brought into close contact with the floor by weight when the chair is seated; When the center rod moves up and down and has a restoring force, the housing having the central rod ring and the spring mounted therein is mounted at the center of the wheel part, and the weight is applied to the chair. It is achieved by configuring the chair not to move in close contact with the floor.

The safety chair of the present invention has the effect of preventing accidents that are broken by the children, the elderly to push the back of the chair while pushing the nose, the ass.

The present invention has the effect of providing a safety chair that the brake pad is in close contact with the ground so that the chair does not move when sitting, the chair is fixed without being pushed back.

The present invention is configured to not move and at the same time configure the brake disk so that the rotating chair is not rotated has an excellent effect that the built-in safety device to prevent the chair from rotating.

Hereinafter, a preferred embodiment of the safety chair of the present invention will be described in detail with reference to the drawings.

Safety chair of the present invention, as anyone can know about the convenience of the wheeled chair, the occurrence of accidents caused by a convenient chair or wheels increases, the risk of sequelae, such as fractures caused by the damage is increased. This is to prevent the wheels from moving when sitting on a chair to prevent children from falling off the chair or sniffing the nose.

The safety chair of the present invention has a center consisting of a spring (110) and a ring (100) for fixing the spring to the bottom of the chair so that the brake pad (150) comes into close contact with the floor by weight when sitting on a chair. The rod 130 and the housing 120 having the center rod ring 100 and the spring 110 formed therein so as to have a restoring force while the center rod moves up and down are mounted on a chair in the center of the wheel leg 170. When the weight is applied, the central rod 130 has a feature that is configured to prevent the chair from moving because the brake pad touches the floor while the spring is compressed down.

The central rod 130 is a central axis supporting the weight of the chair 300 and is fixed to transmit the weight to the wheel leg 170. When a weight (human body weight) is applied to the central rod, a rubber material is formed on the end of the central rod to form a brake pad 150 so as to be in close contact with the bottom surface so that the chair does not push or move.

In addition, the center rod 130 is to be restored by the spring 110 when the weight of the chair disappears, the center rod is in a state raised to the top.

The ring 100 is configured to press the spring 110 on the central rod 130, and is coupled to the housing 120 including the spring.

The housing 120 was mounted at the center of the wheel legs constituting the wheel 160 to fix the spring 110 and at the same time serve as a guide to move the central rod 130 in the vertical direction.

In the present invention shown in FIG. 2, when the seat is seated on a chair, the spring is pulled down by weight, and the brake pad mounted on the end of the center rod comes into close contact with the ground to act as a brake. On the contrary, when arose from the chair, the central rod is raised by the restoring force of the spring 110, and at the same time, the brake pad is released from the ground, and the brake is released to allow the chair to move.

Safety chair of another embodiment of the present invention shown in Figure 3 is configured a brake on the central rod in order not to rotate when sitting on the chair.

The upper portion of the housing 120 to prevent the central rod from rotating to form a brake disc 210 of the disc to friction with the brake disc was configured a pressure pad 190 in the central rod 130 so as not to rotate. Or by mounting the flange 200 to be coupled to the central rod was fixed to the fixing bolt 180.

The pressure pad 190 configured as described above and orthogonal to the surface of the brake disc is configured to descend and rise according to the weight acting on the central rod. When the seat 110 is formed between the flange 200 fixing the pressure pad 190 and the brake disc, the pressure pad connected to the center rod overcomes the spring force of the spring when the seat is seated on the chair. The brake is applied.

In the case of rising from the chair, the central rod is raised by the elasticity of the spring, and the pressure pad 190 is operated to fall off the brake disc.

Another embodiment shown in Figure 4 is configured to rotate when sitting in a chair and to take a brake when waking up.

The "c" shaped flange 220 is coupled to the center rod 130 by fixing the bolt 180, and the pressure pad 230 is mounted at the end of the "c" shaped flange to the lower surface of the brake disc 210. The pressure pad was configured to be in close contact.

The brake disc 210 is mounted on the upper part of the housing 120, and is mounted between the "c" shaped flanges to press and contract the spring 110 when sitting on a chair, and the central rod 130 is lowered to press the pad. The brake will be released from the brake disc surface. At this time, the chair can rotate.

In the case of rising from the chair, the central rod 130 is lifted by the elastic force of the spring, and the raised pressure pad is in close contact with the brake disc surface and the brake is in a locked state and thus cannot rotate.

As described above, the present invention has been described with reference to the embodiment illustrated in the drawings, but this is only an example, and those skilled in the art may make various forms of deformation and other equivalent embodiments therefrom. Will understand. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
