Abstract

(57) [Summary] [Problem] The handrail of the stairs so far has been a smooth cylindrical shape. Therefore, for infants and the elderly, or sick or physically handicapped people with extremely weak grip, they could not grip and hold the handrail firmly, and sometimes fell down stairs. A spiral grip is formed by winding a continuous projection having a semicircular cross section clockwise (for right hand) or counterclockwise (for left hand) along the outer circumference of an elongated round bar having a thickness that can be gripped with one hand. A bar is formed and used for the handrail of the stairs. Since five screws are inserted between the protrusions of the spiral and tightened, the hand is firmly fixed to the handrail so that the hand does not slip or come off, and it is possible to climb down the stairs safely. This grip bar can be used as a standing bar in an entrance, a toilet or a bathroom, and can also be used as a handle for a fork or a spoon if it is reduced in size and reduced in size.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to the shape and structure of a handrail provided for climbing up and down stairs, and a handle of a fork and a spoon.

[0002]

[Prior art]

 Conventional handrails, stairs, and forks and spoons have a cylindrical shape with a smooth longitudinal direction, and are smooth when grasped by hand.

[0003]

[Problems to be solved by the invention]

 For this reason, some people with weak grip, such as infants and the elderly, as well as the sick and physically handicapped, fall down the stairs due to insufficient grip, or securely fix the handle of a fork or spoon held in their hands. Some people are unable to eat well because they cannot do so, and are concerned about health and nursing care.

[0004]

[Means for Solving the Problems]

 Therefore, in order to assist and rescue these people with weak grip strength, spiral stairs (2) and (3) are provided on the grip bar (1) for the stair railing, and the fork (5) and spoon Regarding (7), small protrusions were also provided on the grip handles (4) and (6).

[0005]

[Embodiment of the invention]

 Claim 1 ... The spiral projection (2) provided along the outer periphery of the round bar (1) is a clockwise spiral, and the projection (2) of the bar (1) when gripped with the right hand. Since five fingers do not enter and move in the valley between the adjacent protrusion (2), even a person with a weak grip does not fall off the stick (1), preventing slipping. Claim 2... The spiral projection (3) provided on the outer periphery of the round bar (1) is a counterclockwise spiral, and the same operation and effect as in claim 1 when gripped with the left hand. To prevent slipping. Claim 3: A fork (5) is attached to one end of a handle (4) obtained by thinning a round bar (1), and a finger wound in a spiral enters a valley firmly and slides. The fork (5) can be fixed without being detached. Claim 4... This is obtained by attaching the spoon (7) to the handle (6) in the same manner as in claim 3, and has the same operation and effect as in claim 3.

[0006]

【Example】

 (A) The round bar of the oak tree (1) is turned on a woodworking lathe to cut out a clockwise spiral continuous projection (2) and grip it with the right hand, and the counterclockwise projection (3) is gripped with the left hand. (A) Spiral projections (2), (3), (4) and (6) are formed from a plastic hard synthetic resin. (C) Spiral round bars (2) and (3) are formed by pressing or punching a thin metal plate. Since (a), (a), and (c) above are all large in diameter, they should be used for the handrails on the left and right of the stairs, and as a stand-up bar for entrances, toilets, and bathrooms. (D) The handle (4) of claim 3 and the handle (6) of claim 4 are both formed to be thinner and shorter than the round bars of claims 1 and 2 and made of metal or synthetic resin at the ends thereof. Attach a fork (5) or spoon (7).

[0007]

[Effect of the invention]

 The spiral grip bar of the present invention has five fingers inserted between the spiral projections and firmly fixed, so it does not slip or come off and compensates for the lack of gripping force, and climbs up and down stairs. It can be used safely for handrails, entrances, toilets, and standing bars in bathrooms, and can be used as a handle on tableware such as forks and spoons.

[Technical field to which the invention belongs]

 The invention relates to the shape and structure of handrails provided for climbing and descending stairs.

[0002]

[Prior art]

 Until now, handrails of stairs had a smooth cylindrical shape in the longitudinal direction, and were smooth when gripped by hand.

[0003]

[Problems to be solved by the invention]

 For this reason, some people with weak grip, such as infants and the elderly, and people who are sick or have physical disabilities, fall down the stairs due to insufficient grip, and are concerned about insurance and nursing care. .

[0004]

[Means for Solving the Problems]

 Therefore, spiral protrusions (2) and (3) are provided on the round bar (1) of the handrail of the stairs in order to assist and rescue these people with weak grip strength.

[0005]

[Embodiment of the invention]

 Claim 1 ... The spiral projection (2) provided along the outer circumference of the round bar (1) is a clockwise spiral, and when held with the right hand, the projection (2) of the bar (1) Since five fingers enter the valley between the adjacent protrusions (2) and do not move, even a person with a weak grip does not fall off the stick (1) and can prevent slipping. Claim 2... The spiral projection (3) provided on the outer periphery of the round bar (1) is a counterclockwise spiral, and when it is gripped with the left hand, the same operation and effect as in claim 1 are obtained. Yes, it can prevent slipping.

[0006]

【Example】

(A) A round bar of oak wood (1) is turned on a woodworking lathe to cut out a clockwise spiral continuous projection (2) and grip it with the right hand, and the counterclockwise projections (2) and (3) are gripped with the left hand. ▲. ▲ (b) Spiral projections (2) and (3) are formed from a plastic hard synthetic resin. ▲ (c) A spiral metal bar (2) (▲ 3) is formed by pressing or stamping a thin metal plate. ▲ The above items (a), (a) and (c) are formed to be thick enough to be grasped by human hands, so they should be used for the handrails on the left and right of the stairs ▲, and as a stand-up support bar at the entrance or bathroom. ▲

[0007] ▲

[Effect of the invention] ▲ The grip bar of the present invention has five fingers inserted between the helical projections and firmly fixed ▲, so it does not slip or come off and compensates for the lack of grip force safely, When used for handrails to go up and down the stairs, or as a standing bar in the entrance, toilet, or bathroom, the effect can be achieved sufficiently safely. ▲
