  However, the handrail cap in the above-described conventional example has a problem that the covering material has a circular cross-sectional shape, so that it is difficult to grip and is slippery even in a gripped state.

  The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a handrail headwood which is easy to grip and is not slippery when gripped.

According to the present invention, the object is
A handrail headwood formed by covering the headwood core material 1 with a covering body 2,
The covering 2 is formed of a cushioning material in a cross-sectional shape with an outer periphery forming a polygon,
Some apex corners are more easily subducted and deformed than the remaining apex corners ,
In addition, the vertical corner portion that is easily subducted and deformed is formed by disposing the gap 3 inside the covering body 2 or between the covering body 2 and the headwood core material 1 corresponding to the vertical corner portion. Is achieved by providing

  In the present invention, since the outer periphery of the covering 2 covering the headwood core 1 is formed in a polygonal shape, the apex portion imparts an appropriate resistance when gripped and effectively prevents circumferential slippage. .

  In addition, since a part of the plurality of apex portions are formed so as to sink and deform more easily than the remaining apex portions, a part of the apex portion with which the palm abuts when gripping the covering 2 is Because it sinks more easily than other parts by gripping force, in addition to an effective anti-slip effect, it feels good when gripped, and a relative hard feeling is generated in the remaining part. In addition, the instability when gripping, which tends to be felt when the whole is soft, is also reduced.

  The outer shape of the covering 2 is an appropriate polygonal shape, preferably a regular polygonal shape. However, in consideration of the balance between the operability such as gripping and sliding and the anti-rotation function, the outer shape is preferably 6 to octagonal, preferably It is formed in an octagonal cross section.

  The vertical angle part that can be easily subducted and deformed can be appropriately determined in consideration of the mounting posture of the handrail, the direction in which the user grips and supports the body in the mounting posture, etc. By disposing every other non-deformable easy apex portion, the above-described performance can be exhibited without considering the mounting posture of the handrail.

  In addition to double-molding the apex portion with a more flexible material, the apex angle portion that is easily subducted and deformed corresponds to the apex angle portion, or within the covering 2 or between the covering 2 and the headwood core 1. It is possible to form the gap 3 between the cover body 2 and the cover body 2 so that the inner peripheral wall surface of the cover body 2 is substantially circular. While forming in a cross section, it can form by providing a ditch | groove in the outer peripheral wall of the headboard core material 1. FIG.

In addition, handrail Kasagi
A handrail headwood formed by covering the headwood core material 1 with a covering body 2,
The covering body 2 is formed of a cushioning material in a cross-sectional shape in which the outer periphery has a polygonal shape, and the centripetal thickness at the apex is thicker than the remaining portion. Can be configured.

By increasing the thickness of the apex corner in the centripetal direction compared to the remaining portion, when the entire covering 2 has the same elasticity, if the same load is applied in the centripetal direction, Maximum sinking.

  As a result, when the covering body 2 is gripped, the apex angle part with which the palm abuts is more likely to sink than the other parts, and the entire covering body 2 is likely to be deformed according to the shape of the palm. In addition to an effective anti-slip effect, the feel when gripped is also good, and the remaining part has a relative hard feeling, so the instability when gripping tends to be felt when the whole is soft Or, the unreliable feeling is reduced.

  Various materials such as soft vinyl chloride and various soft elastomers can be used as long as the cushion 2 exhibits appropriate cushion performance when grasped, but a foamed synthetic resin material is used. In this case, the cushion performance can be appropriately adjusted by adjusting the foaming rate and the like. In general, foams have problems such as being easily soiled, easily scratched, and easily torn. However, by disposing the skin layer 4 that is harder than the main body 5 on the surface of the covering 2, these problems can be solved. Effectively eliminated. A semi-rigid synthetic resin material can be used for the skin layer 4.

The cover 2 is mechanically attached to the cover core 1 in addition to inserting the cover core 1 into the cover 2 formed into a tube shape and softened by heat or the like to cover the entire periphery of the cover 1. It can be something that can be locked.
The headboard core material 1 and the cover body 2 are formed in a substantially C-shaped cross-sectional shape opened to one side, and the cover body 2 has an open edge portion as an open edge of the headboard core material 1. It can be configured by being locked.

  In this case, if the engaging portion 6 of the cover 2 to the headboard core material 1 is formed by integrally molding a hard synthetic resin, the strength of mounting the cover body 2 on the headboard core material 1 increases, and the cover body is inadvertent. 2 can be prevented from falling off.

  ADVANTAGE OF THE INVENTION According to this invention, it can make it easy to hold | grip a handrail head board, and can be made not to slip easily when grasped.

It is a figure which shows the handrail using the handrail headwood by this invention, (a) is a top view, (b) is a front view, (c) is the 1C-1C sectional view taken on the line of (b). It is sectional drawing of handrail Kasagi. It is a figure which shows the modification of FIG. It is a figure which shows the effect | action of a handrail Kasagi. It is sectional drawing which shows the other modification of handrail Kasagi.

  FIG. 1 shows a handrail (A) using the handrail cap of the present invention. In this embodiment, the handrail (A) is configured as a wall handrail arranged along the wall surface 7, and is formed by fixing the handrail headboard (B) to the bracket 8 fixed to the wall surface 7 at a predetermined interval. . An end cap 9 for end portion processing is fixed to the terminal portion of the handrail headboard (B) as appropriate.

  The bracket 8 is manufactured by cutting, for example, an extrusion mold of a metal material having a predetermined cross-sectional shape with a predetermined width. The bracket 8 has a wall surface fixing piece 8a at one end and a head fixing piece 8b at the other end, and is fixed to the wall surface 7 by the wall fixing piece 8a. In this embodiment, the wall surface fixing piece 8 a is fixed by using a nut 11 that is fastened to an anchor 10 that is previously installed on the wall surface 7.

  As shown in FIG. 2, the handrail headboard (B) is formed by covering the headboard 1 with a cover 2. The headboard core material 1 is formed of a hard material such as metal, and in this embodiment, it is formed of an aluminum extrusion mold material in consideration of the easiness of bending when a bent handrail is constructed. The headboard core material 1 has a substantially C-shaped cross-sectional shape with one side open, and fixing to the bracket 8 is performed by fixing a headboard fixing piece 8 a inserted from the open portion with a screw 12. . Two positioning protrusions 1a are provided on the innermost wall surface of the hollow portion of the headboard core 1 in order to position the inserted headboard fixing piece 8b.

  The outer peripheral wall of the headwood core material 1 has a shape in which three concave grooves 1b are formed in a cylindrical outer peripheral wall, and the concave grooves 1b and the open portions are spaced 90 degrees around the center of the cylindrical outer peripheral wall. The wall surface which is arranged and does not have the recessed groove 1b and the open portion is used as the support protrusion 13. Moreover, the fitting groove 13a in which the latching | locking part 6 mentioned later is fitted is formed in the support protrusion 13 which faces an open part.

  On the other hand, the covering 2 is formed by disposing a hard or semi-hard skin layer 4 on the surface of the main body 5 obtained by foaming a foamed synthetic resin. The skin layer 4 is formed by integrally molding semi-rigid PVC, elastomer, or the like, and is desirably adjusted so that the surface hardness is approximately 30 to 50 in terms of JISA hardness.

  As shown in FIG. 2, the covering body 2 has an octagonal outer periphery and is formed in a C-shaped cross section by opening the apex portion corresponding to the open portion of the headboard core material 1. Moreover, the inner periphery of the covering 2 is formed by an arc that substantially matches the curvature of the outer peripheral wall of the support ridge 13 of the coping core 1, and as a result, the thickness distribution is as shown in FIG. In addition, the thickness (tt) in the centripetal direction at the apex angle portion is the maximum, and the thickness (te) at other portions is smaller than this.

  Further, a semi-rigid PVC or the like is integrally formed at the open end portion of the covering 2 to form a locking portion 6. The locking portion 6 is formed by projecting a ridge in the center direction, and the covering 2 is attached to the headboard core material 1 after covering the outer peripheral wall of the headboard core material 1 with the cover body 2. The engaging portion 6 is fitted in the fitting concave groove 13a of the headwood core material 1. The locking portion 6 is provided with a hollow hole 6a for adjusting the hardness of the protrusion to make the fitting operability to the fitting groove 13a and the fitting strength suitable for workability.

  In a state in which the covering body 2 is mounted, the inner peripheral wall of the covering body 2 is supported by four supporting protrusions 13 and maintains a predetermined shape. When the user grips the handrail headboard to support the body in this state, the apex portion where the gap 3 is disposed between the headboard core 1 sinks. In addition, as shown in the right half of FIG. 4A, the apex angle portion supported by the support protrusion 13 has the maximum thickness in the centripetal direction on the apex, and is more likely to sink than the periphery. Therefore, as shown in the left half in FIG. 4B, the vicinity of the vertex first sinks.

As a result, in the cross-sectional direction, the apex portion mainly sinks according to the magnitude of the force and the load point, so that it fits to the palm, fingers and the like as a whole, and a suitable feel is obtained, and the circumferential direction is obtained. Slip is prevented. Further, as shown in FIG. 4 (b), the sinking of the handrail coping (B) in order to generate a particular position in the longitudinal direction, the slip is also prevented in the longitudinal direction.

  In FIG. 2, the handrail headboard (B) is formed by disposing the semi-hard skin layer 4 on the outer peripheral wall of the main body part 5, but as shown in FIG. Alternatively, a semi-hard inner wall skin layer 14 can be formed. The inner wall skin layer 14 prevents the main body part 5 from tearing due to excessive force from the support protrusion 13 when a large load is applied to the handrail head (B), and further controls foaming of the main body part 5 In this embodiment, it is formed by extending the locking portion 6 along the inner peripheral wall. However, as with the skin layer 4, a separate material is used simultaneously. It may be formed or formed as an extension of the skin layer 4.

  FIG. 5 (a) shows another modification of the handrail cap (B). In this modified example, horizontal support surfaces 13b are formed on the two rows of support protrusions 13 arranged at the upper portion, and support the bulges 2a formed on the inner wall of the cover 2. By forming the bearing surface 13b as described above, it is possible to effectively prevent twisting of the covering body 2 when a load in the twisting direction is applied to the handrail headboard (B).

  Moreover, in this modification, the latching | locking part 6 of the coating | covering body 2 is formed in the hook shape which can be latched to the to-be-latched step part 1c formed in the open end of the coping core material 1. FIG. Even in such a configuration, the inner wall skin layer 4 can be provided as shown in FIG.
