Description

  The present invention relates to a handrail provided on a wall surface of a building such as a general house or a public facility.

  As a conventional movable handrail related to the present invention, one in which a handrail bar is pivotally supported by a bracket fixed to a wall surface is known (see, for example, Patent Document 1). In the case of the movable handrail described in Patent Document 1, since the mechanism such as a bracket that pivotally supports the handrail bar with respect to the wall surface is exposed, the appearance is inferior. Therefore, like the movable handrail 90 shown in FIG. 9, the cover 95 covers the front surface of the bracket 92 fixed to the wall surface 91, and covers the cover 95 over the rotation range of the holding member 94 that holds the handrail bar 93. It is conceivable as a countermeasure to provide a structure in which an opening 95a is provided and the holding member 94 of the handrail bar 93 protrudes from the opening 95a of the cover 95.

  In the movable handrail 90 shown in FIG. 9, as shown in FIG. 10, when the handrail bar 93 is rotated in the standing direction, between the edge of the opening 95 a of the cover 95 and the holding member 94, There is a risk that the user may pinch fingers. On the other hand, in order to avoid this, if the end edge of the opening 95a of the cover 95 is expanded from the rotation range of the holding member 94, a mechanism such as a bracket 92 inside the cover 95 from the gap between the holding member 94 and the opening 95a. As a result, the appearance is impaired.

  The problem to be solved by the present invention is to provide a movable handrail that is excellent in safety during the turning operation of the handrail bar and has good appearance.

The movable handrail of the present invention is a movable handrail in which a handrail bar gripped by a user is configured to be rotatable with respect to a wall surface.
A bracket fixed to the wall surface to pivotally support a holding member that holds the base end portion of the handrail bar; and
A cover that is mounted so as to cover the front surface of the bracket, and that has an opening that can be rotated in a state in which the holding member penetrates,
When the holding member is turned to the wall surface side, a spacer is provided that forms a bottomed recess for retracting a finger that is located between an edge of the opening and the holding member. .

  With such a configuration, when the handrail bar is rotated to the wall surface side, a bottomed recess that allows the finger to retract is formed between the edge of the opening and the holding member. There is no, and it is excellent in safety during the turning operation. In addition, the space between the opening of the cover and the holding member is covered by the bottom of the bottomed recess, and the inside of the cover is difficult to see from the outside. Note that the spacer may be a separate member from the cover or the bracket, but may be a structure integrated with the cover or the bracket.

  Here, it is desirable that an inclined surface having a shape that approaches the wall surface side as the distance from the rotation center of the holding member increases on the wall surface side of the bottomed recess. With this configuration, the finger pushed by the holding member that rotates toward the wall surface together with the handrail bar is smoothly pushed out of the cover along the inclined surface of the bottomed recess, further improving safety. To do.

  The holding member includes a columnar rotation base having a rotation center as a center axis, and a connecting portion protruding from the rotation base and connected to a base end of the handrail bar, Providing the spacer with a curved surface close to the outer peripheral surface of the rotating base of the holding member and curved along the outer peripheral surface prevents the fingers from entering between the spacer and the holding member, which is effective for ensuring safety. is there.

  On the other hand, a diameter-expanded portion that bulges toward the curved surface may be provided in a region of the rotation base of the holding member that faces the curved surface of the spacer. With such a configuration, while avoiding an increase in the size of the holding member and adjusting the amount of expansion of the enlarged diameter portion at the time of design, the rotation center of the holding member is placed at a desired position, and into the cover. It is possible to prevent fingers from penetrating deeply. The enlarged diameter portion may be provided by expanding a part of the rotation base, but another member that rotates integrally with the rotation base may be provided on the rotation base.

  According to the present invention, it is possible to provide a movable handrail that is excellent in safety during the rotation operation of the handrail bar and has a good appearance.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing a movable handrail according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the movable handrail shown in FIG. 1, and FIG. 3A is a perspective view of the spacer shown in FIG. FIG. 4B is a perspective view of the spacer as viewed obliquely from below. 4 is a perspective view showing a rotating state of the movable handrail shown in FIG. 1, and FIG. 5 is a vertical sectional view in the vicinity of a holding member of the movable handrail shown in FIG.

  As shown in FIGS. 1 and 2, the movable handrail 10 of the present embodiment is configured such that a substantially U-shaped handrail bar 11 held by a user is rotatable with respect to a wall surface 12. The substantially T-shaped holding member 13 that holds the handrail bar 11 is configured such that a columnar rotation base portion 13b corresponding to a horizontal portion of the T shape can rotate to a substantially U-shaped bracket 14 via a support shaft 13c. A base end portion 11c of the handrail bar 11 is connected to a connecting portion 13a that is pivotally supported and corresponds to a vertical portion of the T-shape. As shown in FIG. 5, which will be described later, the handrail bar 11 is formed of a cylindrical stainless steel tube 11a and a cladding tube 11b made of vinyl chloride that tightly covers the outer periphery thereof.

  In the bracket 14 formed by bending a flat plate material into a substantially U shape, a fixing portion 14b corresponding to a vertical portion of the U shape is fixed to the wall surface 12 using a screw 18 (see FIG. 5). A rotating base portion 13b of the holding member 13 is rotatably supported between a pair of bearing portions 14a protruding forward from both sides of 14b.

  A cover 15 is attached to the bracket 14 so as to cover the front surface thereof, and an opening 15 a that can be rotated in a state in which the connecting portion 13 a of the holding member 13 penetrates is opened on the front surface of the cover 15. Further, when the holding member 13 is rotated to the wall surface 12 side (see FIG. 4), a bottomed recess 16a for retracting fingers is formed between the edge 15b of the opening 15a and the outer periphery of the holding member 13. A spacer 16 is provided. Further, a diameter expanding member 17 is attached to a part of the outer periphery of the rotation base portion 13 b of the holding member 13.

  As shown in FIGS. 3 and 5, the spacer 16 is fixed with screws 19 in a state where the back surface portion thereof is in close contact with the fixing portion 14 b of the bracket 14. The central portion of the spacer 16 has a U-shaped bay portion 16b having the same shape as the vicinity of the edge 15b (see FIG. 2) of the opening 15a of the cover 15, and a flat bottom portion 16c is provided below the U-shaped bay portion 16b. ing. A curved surface 16e that is close to the outer peripheral surface of the rotation base portion 13b of the holding member 13 and that is curved in a concave shape along the outer peripheral surface is formed below the bottom portion 16c of the spacer 16. On both sides of the bay portion 16 b of the spacer 16, a pair of square portions 16 d protruding forward are provided.

  Further, as shown in FIG. 5, a diameter expansion member 17 is attached to a region of the rotation base portion 13 b of the holding member 13 facing the curved surface 16 e of the spacer 16, and the curved surface 16 e of the spacer 16 is attached to the outer surface of the diameter expansion member 17. A curved surface 17a that bulges toward is provided.

  Here, based on FIG. 4, FIG. 5, the rotation state of the handrail bar 11 is demonstrated. As shown in FIGS. 4 (a) and 5 (a), when the handrail bar 11 in the horizontal state is turned to the wall surface 12 side, as shown in FIGS. 4 (b) and 5 (b), the opening is opened. A bottomed recess 16a in which the finger F can be retracted is formed between the edge 15b of the portion 15a and the holding member 13. For this reason, the fingers F are not sandwiched between the edge 15b of the opening 15a and the holding member 13, and the safety during the turning operation is excellent. Further, since the space between the opening 15a of the cover 15 and the holding member 13 is covered with the bottom 16c of the bottomed recess 16a and the inside of the cover 15 is difficult to see from the outside, the appearance is good.

  Further, as described above, the spacer 16 is provided with the curved surface 16e which is close to the outer peripheral surface of the rotation base portion 13b of the holding member 13 and is curved along the outer peripheral surface. Since the finger F cannot enter during this period, it is effective for ensuring safety. Furthermore, a diameter-expanding member 17 having a curved surface 17a that bulges toward the curved surface 16e is fixed to a region facing the curved surface 16e of the spacer 16 in the rotation base 13b of the holding member 13. Therefore, by adjusting the thickness of the diameter-expanding member 17 at the time of design, the cover 15 is arranged while the rotation center (support shaft 13c) of the holding member 13 is disposed at a desired position while avoiding an increase in size of the holding member 13. It is possible to prevent the finger F from entering the inside deeply.

  Further, in the movable handrail 10, the thickness of the diameter-expanding member 17 is designed so that the rotation center (support shaft 13c) of the holding member 10 substantially coincides with the center of the front surface of the cover 15 formed in an arc shape. (See FIG. 5). By adopting such a configuration, the amount of exposure of the connecting portion 13a from the opening 15a is substantially constant in the rotation range of the holding member 13, so that the appearance is kept good.
