Abstract

PROBLEM TO BE SOLVED: To provide a handrail which is easily grasped with light power of a hand and in which the hand is unlikely to slip when walking along a pedestrian way or inside of a construction or going up and down a slope or stairs, by enabling even the aged, the handicapped, a child or a general person whose grip of the hand is weakened, to support the body action safely and at ease with light power of the hand.SOLUTION: In the handrail which is mounted while setting a length direction along the inclination of stairs, a trapezoidal part (A) formed in a trapezoidal shape and a linear part (4) are provided alternately in the length direction. The trapezoidal part (A) includes: a rising portion (1), being substantially perpendicular to a floor surface, which plays a role of supporting the action of moving up while being lightly grasped and making the body closer thereto without bending the wrist; and a parallel portion (2) and an inclined portion (3) which are grasped lightly to move up while placing an elbow thereon.

Description

  The present invention relates to handrails installed on sidewalk slopes, stairs, building toilets and the like for safe walking by ordinary pedestrians as well as elderly people, persons with disabilities and children.

There are handrails to assist the body movements for people to hold hands on and walk up and down stairs, slopes and stairs in the sidewalks and buildings. In addition, handrails that assist the operation for supporting the body, such as a toilet in a building, are provided. Conventional handrails that have been installed in the past are elderly, disabled people, children, etc. whose hand grip strength has weakened, because the surface is flat and smooth, so the wrist is bent, The handrail could not be held firmly. In addition, there is an inconvenience as means for assisting body movements by sliding hands.

JP 2003-56149 A (page 3, FIGS. 1, 2 and 3) JP 2002-201784 A (page 13, FIG. 1) Utility Model Registration No. 3122522

The present invention assists safe and secure body movement with the power of a light hand even for the elderly, handicapped, children, or ordinary people with weak hand grip. It is an object to provide a handrail that makes it easy to grip up and down with light hand power and prevents the hand from slipping.

The measures taken to solve the above problems are as follows.
The first means is a handrail characterized in that trapezoidal portions (A) and linear straight portions (4) formed in a trapezoidal shape are alternately provided in the longitudinal direction.

The second means is a trapezoidal part (A) formed in a trapezoidal shape, and a lightly gripped part with an upright part (1) substantially perpendicular to the floor surface that serves to assist in ascending the body while gripping the grip part. A handrail characterized in that it is provided with a parallel part (2) and an inclined part (3) that can be raised while attaching an elbow.

The present invention has the following effects.
(A) When the handrail is provided in the length direction along the inclination, the trapezoidal trapezoidal portion (A) and the linear straight portion (4) are alternately provided in the length direction. The hand can be slid and moved along the handrail so as not to leave the handrail, and the anxiety that the hand leaves the handrail can be easily removed. Moreover, if it moves along a handrail, even if the grasped hand slips, the trapezoidal trapezoidal part (A) of the hand is likely to stop and stop.

(B) When a handrail is provided along the slope in the length direction, when going up a slope or a staircase, an upright portion (1) substantially perpendicular to the floor surface of the handrail trapezoid (A) is placed on the wrist. Gently grip without bending, and can easily reach the next tread of the stairs while pulling the body, even for people with weak gripping power, safely and easily, easily and easily assisting the ascending movement, and going up the stairs first Proceed to

When going down a slope or stairs, lightly grasp the straight part (4) of the handrail, attach an elbow to the sloped part (3) and parallel part (2) of the trapezoidal part (A), , Grab the vertical part (1), which is almost perpendicular to the floor of the trapezoidal part (A), push away the body, move your foot to the next descending tread, slide your hand down, etc. There is little risk of.

(C) If the handrail is installed in a place where it stands up and bends, when sitting on the toilet seat, lightly grasp the straight part (4), attach the elbow, and bring the body into a trapezoidal shape. Bend down while moving to the inclined part (3) and parallel part (2) of the part (A), and the upright part (1) substantially perpendicular to the floor surface of the trapezoidal part (A), without bending the wrist While grasping lightly, pulling and supporting the body, it is possible to sit safely and stably on the toilet seat, and there is little risk of hitting the buttocks.

  When standing up from the toilet seat, put your hand on the straight part (4), grab the upright part (1), which is almost perpendicular to the floor of the trapezoidal part (A), without bending your wrist, It is possible to stand up easily by raising the body, raising the waist, and moving the grasped hand to the parallel part (2) and the inclined part (3).
