  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  The handrail 1 of this embodiment includes a grip portion 2, a male screw portion 3 provided integrally at one end portion of the grip portion 2, and a female screw portion 4 provided integrally at the other end portion of the grip portion 2. Handrail unit member 5, connecting portion 6 of handrail unit member 5, female screw portion 7 provided integrally at one end portion of connecting portion 6, and mounting rod provided integrally at the other end portion of connecting portion 6 The handrail unit member 5 and the end support member 9 are coupled by being screwed into a pair of end support members 9 including the portion 8, the female screw portion 4 of the handrail unit member 5, and the female screw portion 8 of the end support member 9. The male screw member 10 is provided. And the both ends of the handrail main body 11 formed by mutually connecting a plurality of handrail unit members 5 are supported by the end support members 9, so that the handrail 1 having a desired length can be placed in a desired installation place, for example, a staircase. It is constructed on the wall of the house.

  The handrail unit member 5 is formed by injection molding, for example, a short straight tube made of synthetic resin having a length of about 20 cm, and a portion excluding both end portions thereof is the grip portion 2. The handrail unit member 5 has a circular cross-sectional shape, and the grip portion 2 corresponds to a portion gripped by the user in the handrail 1. The handrail unit member 5 is formed integrally with one end of the grip portion 2 with an outer diameter smaller than the outer diameter of the male screw portion 3, and an inner diameter corresponding to the outer diameter of the male screw portion 3 at the other end of the grip portion 2. The female thread portion 4 is integrally formed. Therefore, when the handrail unit members 5 are connected to each other, the outer peripheral surface is substantially flush.

  The male screw portion 3 has a screw shape corresponding to the female screw portion 4. Therefore, the male screw portion 3 can be screwed into the female screw portion 4 and the female screw portion 9. The base end 3a of the male screw portion 3 is formed to have an outer diameter larger than the outer diameter of the other portion, that is, the male screw portion. The base end 3a has a shape in which a male ring is not formed on the surface and a chamfered ring is integrally formed. Corresponding to the base end 3a of the male screw portion 3, the distal end 4a of the female screw portion 4 includes an unthreaded portion including a tapered surface that expands outward from the inner diameter of the female screw portion. The inner diameter of the distal end 4a is substantially equal to the outer diameter of the proximal end 3a. Thereby, for example, when the handrail unit member 5 is connected, the distal end 4a of the female thread portion 4 of the other handrail unit member 5 is in close contact with the proximal end 3a of the male thread portion 3 of one handrail unit main body member 5, and the proximal end 3a. As a result, the connected state is reinforced.

  Each end support member 9 is made of a synthetic resin formed by injection molding, like the handrail unit member 5. The connecting portion 6 has a shape extending from the center portion of the mounting flange portion 8 made of a disk to a predetermined length perpendicular to the mounting flange portion 8, then bent at about 90 degrees and extending parallel to the mounting flange portion 8. The outer diameter of the connecting portion 6 is equal to the outer diameter of the handrail unit member 5, and therefore the female screw portion 7 of the end support member 9 has a screw shape equal to the female screw portion 4 of the handrail unit member 5, The tip 7a is formed in the same shape as the tip 4a, that is, in an unthreaded portion including a tapered surface. For example, mounting holes 12 through which screws pass are formed in the mounting flange 8 at four locations for fixing the end support member 9.

  The male screw member 10 is made of a synthetic resin hollow straight circular pipe material, and is formed by injection molding. The male screw member 10 includes a large-diameter portion 10 a corresponding to the base end 3 a of the male screw portion 3 of the handrail unit member 5 at the substantially center in the longitudinal direction, and has the same screw shape as the male screw portion 3. The outer diameter of the large diameter portion 10a is larger than the outer diameter of the male screw portion of the male screw member 10, and is substantially equal to the inner diameter of the tip 4a. Therefore, it can be screwed into both the female screw portion 4 of the handrail unit member 5 and the female screw portion 7 of the end support member 9, and when it is screwed into the handrail unit member 5 and the end support member 9, it has a large diameter. The part 10a reinforces the connected state.

That is, the handrail unit member 5 connects the five by sequentially repeating the screwing of the male screw portion 3 into the female screw portion 4 of the other handrail unit member 5 to be connected. Then, the male screw member 10 is screwed into the female screw portion 4 of the handrail unit member 5 located at the end portion, and a series of handrail main bodies 11 in which male screws are present at both ends are formed. In this state, the total length of the handrail main body 11 can be finely adjusted by adjusting the screwing condition of each male screw portion 3 of the handrail unit member 5.

  Next, end support members 9 are attached to both ends of the handrail body 11. Since the handrail main body 11 is a male screw formed by the male screw portion 3 and the male screw member 10 of the handrail unit member 5 at both ends, the handrail main body 11 is screwed into the female screw portion 7 of the end support member 9. The end support member 9 can be connected to the member 11. In this state, by adjusting the tightening degree of the end support members 9, the back surface of the attachment flange portion 8 of each end support member 9 is fixed in a substantially flush direction.

  Thereafter, the screws are tightened through the respective attachment holes 12 in a state where the attachment flange portion 8 of the end support member 9 is in close contact with the wall to which the handrail 1 is attached. Thereby, the end support member 9 is fixed to the wall, and the handrail body 11 is supported by the pair of end support members 9, so that the attachment of the handrail 1 is completed.

  According to such a configuration, since the handrail 1 can be constructed by three types of parts including the handrail unit member 5 manufactured by injection molding, the end support member 9 and the male screw member 10, the parts constituting the handrail 1 It is possible to reduce the cost required for manufacturing and managing. Moreover, since the male screw portion 3 and the female screw portion 4 are integrally formed at one end and the other end of the handrail unit member 5, the number of parts for connection can be reduced. Moreover, since it is the structure of such a handrail unit member 5, the male screw part 3 and the female screw part 4 of each handrail unit member 5 can be connected by the operation | work only screwed in mutually, The construction operation | work of the handrail 1 Can be simplified. Furthermore, since the male screw portion 3 and the female screw portion 4 are integrated, the strength can be increased as compared with the case where the handrail unit member 5 is connected using another component. Furthermore, since the outer diameter of the base end 3a of the male screw portion 3 and the large diameter portion 10a of the male screw member 10 is increased so that they are fitted into the tips 4a and 7a of the respective female screw portions 4 and 7, the handrail unit member 5 and the end support member 9 can be reinforced.

  Moreover, the handrail 1 of various desired length can be easily constructed | assembled by adjusting the number of the handrail unit members 5. FIG.
