Further, a side wall side screw insertion hole 4 a is formed in a portion of the side wall 4 corresponding to the female screw of the fixing nut 28.
Further, a positioning hole 4b as a fitted portion is formed in a portion of the side wall 4 located near the lower side of the side wall side screw insertion hole 4a. The distance between the positioning hole 4b and the side wall side screw insertion hole 4a corresponds to the distance between the through hole 25a of the wall side bracket 21 and the positioning projection 26.

The fixing screw 35 has a head portion 36 and a shaft portion 37 protruding from the head portion 36, and a flat surface of the head portion 36 positioned around the shaft portion 37 constitutes a contact surface.
The handrail fixing means 40 includes a screw 41 and a nut 42.

Next, a structure for attaching the handrail member 11 to the side wall 4 via the handrail support means 20 will be described.
Here, for example, a description will be given of a structure in which the handrail member 11 is attached to the side wall 4 positioned at one side of the entrance / exit 3 using the handrail support means 20, but the handrail member 11 is attached to the other side wall 4 by the handrail support means. The structure attached using 20 is the same.

In FIG. 1, a pair of handrail support means 20 are provided on the side wall 4 so as to be spaced apart from each other in the depth direction of the cab 1.
The handrail member 11 is arranged with its longitudinal direction coinciding with the depth direction of the cab 1.
The handrail member 11 is supported by a pair of handrail support means 20 provided on the side wall 4 in the vicinity of both ends in the longitudinal direction.

2 to 6, the wall-side bracket 21 is disposed so that the side wall abutting bottom 25 extending from one end of the support main body 22 abuts on the surface of the side wall 4 that is symmetrically mounted.

At this time, the positioning protrusion 26 is fitted into the positioning hole 4 b formed in the side wall 4, and the wall side bracket 21 is pressed against the side wall 4. As a result, the wall-side bracket 21 is positioned at a predetermined mounting position, maintained in a predetermined posture, and prevented from being moved along the surface of the side wall 4.
Further, the opening of the recess 23 is directed downward.

Further, the fixing nut 29 is inserted in the through hole 25a formed in the side wall abutting bottom 25 and the side wall side screw insertion hole 4a formed in the side wall 4 and fixed to the back surface of the side wall 4 in advance. 28 is screwed. Thereby, the wall side bracket 21 is fastened and fixed to the side wall 4 by the holding means 27 including the attaching / detaching screw 29 and the fixing nut 28, and the axial direction of the support main body portion 22 coincides with the direction orthogonal to the side wall 4. Directed to.

Further, the screw insertion hole 24 that is a long hole comes to the portion of the support main body portion 22 that faces downward so that the long axis direction coincides with the longitudinal direction of the handrail member 11. ing.
The attachment / detachment screw 29 can be loosened and removed from the cab 1, and the wall bracket 21 is detachably held by the holding means 27 from the cab 1.

The decorative cover 50 is externally fitted to the support main body 22.
Further, in the handrail member 11, the handrail through hole 11 a of the handrail member 11 is aligned with the through hole 33 a of the handrail contact bottom portion 33. Then, the shaft portion of the screw 41 protruding from the handrail member 11 is inserted into the through hole 33a and the handrail through hole 11a by inserting the shaft portion of the screw 41 whose head is disposed inside the supported main body portion 31. The tip of is screwed onto the nut 42. Thereby, the handrail contact bottom 33 and the handrail member 11 are tightened between the head of the screw 41 and the nut 42, and the handrail member 11 and the handrail side bracket 30 are integrated.

Further, the supported main body portion 31 is inserted from the opening at the protruding end of the support main body portion 22, the supported main body portion 31 and the support main body portion 22 are fitted together, and the handrail side bracket 30 is supported by the wall side bracket 21. Is done.
At this time, the entire edge portion on one end side of the supported main body portion 31 is disposed between the inner wall surface of the support main body portion 22 and substantially no gap. Further, substantially the entire area of the supported main body 31 is inserted into the support main body 22.

Thereby, the handrail member 11 is supported by the wall side bracket 21 via the handrail side bracket 30.
In addition, the axis of the supported main body 31 overlaps the axis of the support main body 22, and the direction of these axes coincides with the direction orthogonal to the side wall 4.

At this time, the screw hole 32 extends at an angle inclined with respect to the side wall 4 so as to be separated from the side wall 4 from one end toward the screw insertion hole 24 toward the other end. The screw contact surface 23 a with which the portion 36 is in contact is orthogonal to the hole direction of the screw hole 32.

In other words, the screw contact surface 23a has a predetermined angle with the direction orthogonal to the side wall 4, and the support main body 22 is moved from a portion located near one end of the support main body 22 toward a portion located near the other end. It is comprised by the plane inclined from the inner side to the outer side.

Here, since the screw contact surface 23a is directed downward, as shown in FIG. 3, the screw contact surface 23a has a predetermined angle α with respect to a horizontal plane perpendicular to the side wall 4, and the support main body portion. It is comprised by the plane which inclines outward from the inner side of the support main-body part 22 toward the site | part located near the other end from the site | part located near the one end of 22. FIG.
Further, an opening at one end of the screw hole 32 is arranged at a position facing the screw insertion hole 24.

Further, the decorative cover 50 is rotated around the support body 22 so that the through hole 51 of the decorative cover 50 overlaps the opening of the recess 23.
Further, since the inner diameter of the decorative cover 50 corresponds to the outer diameter of the support main body portion 22, the decorative cover 50 and the support main body portion 22 are arranged without a substantial gap.

The shaft portion 37 of the fixing screw 35 is inserted into the through hole 51, the recess 23, and the screw insertion hole 24, and is screwed into the screw hole 32 to tighten the fixing screw 35. The part 31 is fastened to each other.

At this time, since the concave portion 23 is arranged downward, the fixing screw 35 is out of the passenger's field of view when the passenger gets into the cab 1. Further, the distance obtained by adding the depth of the recess 23 and the length of the through hole 51 in the hole direction is approximately equal to the thickness of the head 36, and the head 36 of the fixing screw 35 is larger than the surface of the decorative cover 50. Protruding is prevented.
As described above, since the fixing screw 35 is not visible to the passenger, the design is improved. Moreover, the designability is further improved by making the decorative cover 50 look good.

As shown in FIG. 6, a gap is formed between the inner peripheral surface of the support main body 22 and the outer peripheral surface of the supported main body 31 except for the wall surface of the support main body 22 that is pressed against the supported main body 31. 55 is formed.
The clearance 55 is due to a manufacturing error in the position where the handrail through hole 11a of the handrail member 11 is formed and a manufacturing error in the position where the side wall screw insertion hole 4a or the positioning hole 4b is formed in the side wall 4. 21 is set in consideration of an error in the installation position.

When the supported main body portion 31 is fitted to the support main body portion 22, a screw hole 32 whose hole direction is set so that one end in the axial direction is separated from the side wall 4 toward the other end is formed in the supported main body portion 31. Then, regarding the effect obtained by making the screw contact surface 23a against which the head portion 36 comes into contact with the fixing screw 35 to be orthogonal to the hole direction of the screw hole 32, the elevator cab handrail device of the comparative example and This will be explained by comparison.

FIG. 7 is a sectional view of a main part of a handrail device for an elevator cab in a comparative example, and FIG. 8 is a fixing screw when a handrail member is pulled in the handrail device for an elevator cab according to an embodiment of the present invention. It is a figure explaining the force which acts on.

7, in the elevator cab handrail device of the comparative example, the screw hole 60 is formed in the supported main body portion 31 instead of the screw hole 32, and the concave portion 53 is formed in the support main body portion 22 instead of the concave portion 23. Other than that, it is configured in the same manner as the handrail device 10 in the elevator cab.

The hole direction of the screw hole 60 is orthogonal to the axial direction of the supported main body 31.
The bottom surface of the recess 53 is configured as a screw contact surface 53 a that is parallel to the axial direction of the support body 22.

First, an operation when the handrail member 11 is pulled away from the side wall 4 in the horizontal direction orthogonal to the side wall 4 in the elevator cab handrail device of the comparative example will be described.
By tightening the fixing screw 35, a frictional force acts between the screw contact surface 53 a and the head 36 of the fixing screw 35. As indicated by the white arrow, the pulling force of the handrail member 11 is transmitted to the fixing screw 35 via the handrail side bracket 30, and this frictional force causes the handrail side bracket 30 to move against the wall side bracket 21. Is prevented from moving in the axial direction of the wall-side bracket 21.

However, if the pulling force of the handrail member 11 is larger than the frictional force between the screw contact surface and the head of the fixing screw 35, there is no play between the screw insertion hole 24 and the shaft portion 37 of the fixing screw 35. 7 is formed, the handrail member 11 is moved together with the handrail side bracket 30 and the fixing screw 35 until the shaft portion 37 comes into contact with the inner wall surface of the screw insertion hole 24, as shown by a one-dot chain line in FIG. Moved.
That is, the handrail member 11 is rattled.

Next, the operation when the handrail member 11 is pulled away from the side wall 4 in the horizontal direction perpendicular to the side wall 4 in the handrail device 10 in the elevator cab will be described.

8, as described above, the screw hole 32 extends so that the center of the hole is separated from the side wall 4 from one end to the other end. And the screw contact surface 23a orthogonal to the hole direction of the screw hole 32 is directed to the direction orthogonal to the side wall 4 from the part located on one end side of the support main body 22 toward the part located on the other end side. The support body 22 is inclined from the inside to the outside at a predetermined angle α.

In this case, when the handrail member 11 is pulled, the head portion 36 of the fixing screw 35 is moved in the direction of biting into the screw contact surface 23a, as shown by the one-dot chain line in FIG.
In FIG. 8, for convenience, the head 36 of the fixing screw 35 is shown to be disposed inside the screw contact surface 23 a, but in reality, the screw contact in the moving direction of the head 36 of the fixing screw 35. Since the surface 23a is located, a wedge effect is achieved in which the movement of the fixing screw 35 is restricted by the screw contact surface 23a, and the fixing screw 35 is not moved.

As described above, in the handrail device 10 in the elevator cab, the wedge effect works. Therefore, even when the handrail member 11 is pulled with a strong force, the handrail member 11 is prevented from rattling and the handrail member 11 is stable. Then, it is held by the handrail support means 20.
Since the support main body 22 and the handrail side bracket 30 are connected and fixed by the fixing screw 35 in a state in which the handrail side bracket 30 is pressed against the support main body portion 22 in advance, the handrail also when the handrail member 11 is pushed in. The member 11 is prevented from rattling.

Next, a method of attaching the elevator cab to the side wall 4 of the handrail device 10 will be described.
First, the support main body portion 22 is disposed on the surface of the side wall 4 by pressing the bottom portion of the support main body portion 22 against the side wall 4 to be attached so that the positioning protrusions 26 are fitted in the positioning holes 4 b.
Next, the attachment / detachment screw 29 is inserted into the side wall side screw insertion hole 4 a and tightened to the fixing nut 28, and the support main body portion 22 is fixed to the side wall 4.
Next, the decorative cover 50 is externally fitted to the support main body 22.

Further, the handrail through hole 11a of the handrail member 11 is aligned with the through hole 33a of the handrail contact bottom 33, and the screw 41 is inserted into the supported main body 31 from one end side of the supported main body 31. Further, the shaft portion of the screw 41 is inserted into the through hole 33a and the handrail through hole 11a, and the nut 42 is screwed into the portion of the shaft portion protruding inside the handrail member 11, so that the handrail member 11 and the handrail side bracket 30 are connected. The cap 12 is attached to the handrail member 11 in advance.

The supported body portion 31 is fitted into the support body portion 22, and the handrail side bracket 30 is pushed into the support body portion 22 until one end of the supported body portion 31 comes into contact with the inner peripheral surface of the support body portion 22. The screw insertion hole 24 and the screw hole 32 are opposed to each other.

Next, the position around the support main body portion 22 of the decorative cover 50 is adjusted so that the through hole 51 of the decorative cover 50 overlaps the concave portion 23, and the shaft portion 37 of the fixing screw 35 is changed to the through hole 51, the concave portion 23, and the screw. The main body 31 to be supported and the main body 22 to be supported are connected and fixed by being inserted into the insertion hole 24 and screwed into the screw hole 32.
By the above, the attachment to the side wall 4 of the handrail apparatus 10 of an elevator cab is completed.
When removing the handrail member 11, the handrail member 11 can be removed from the wall side bracket 21 together with the handrail side bracket 30 by removing the fixing screw 35.

According to the elevator cab handrail device 10 according to the present invention, the screw hole 32 extends from one end directed to the screw insertion hole 24 toward the other end away from the side wall 4, and the fixing screw 35. A screw contact surface 23 a including a portion with which the head portion 36 is contacted at the time of tightening is orthogonal to the hole direction of the screw hole 32.

Therefore, in a state where the shaft portion 37 of the fixing screw 35 is screwed into the screw hole 32 and the head portion 36 is brought into contact with a predetermined region of the support main body portion 22, the pulling force of the handrail member 11 in the direction away from the side wall 4 is The fixing screw 35 screwed into the handrail side bracket 30 to which the handrail member 11 is attached acts in a direction to bite into the screw contact surface 23a. For this reason, since the movement of the fixing screw 35 is restricted, it is possible to prevent the handrail side bracket 30 from rattling if the handrail side bracket 30 is previously pushed into contact with the wall side bracket 21.

Moreover, the positioning hole 4b as a to-be-fitted part is formed in the predetermined site | part of the side wall 4 to which the wall side bracket 21 is attached. And the wall side bracket 21 has the positioning protrusion 26 in the end surface part orient | assigned to the side wall 4, and it fits the positioning protrusion 26 and the positioning hole 4b, and arrange | positions the wall side bracket 21 in the side wall 4, thereby the wall side The bracket 21 is immediately positioned at the desired mounting position.
Thereby, the labor of the attachment work to the side wall 4 of the wall side bracket 21 can be reduced significantly.

The screw insertion hole 24 is a long hole formed in a predetermined portion of the outer peripheral portion of the support main body portion with the long axis direction coinciding with the longitudinal direction of the handrail member 11. Accordingly, the handrail is caused by a manufacturing error in the position where the handrail through-hole 11a of the handrail member 11 is formed and a manufacturing error in the longitudinal direction of the handrail at the position where the side wall screw insertion hole 4a or the positioning hole 4b is formed in the side wall 4. Even if an error in the installation position of the side bracket 30 and the wall side bracket 21 occurs, the handrail side bracket 30 can be moved in the long axis direction of the long hole by the gap 55, so that the handrail side bracket 30 can be moved to the wall side. The bracket 21 can be supported.

In addition, since the decorative cover 50 is detachably provided on the support main body 22, the replacement of the decorative cover can be performed at a low cost without replacing the support main body 22 and the design is improved.

Further, since the cap 12 that is smoothly curved is provided at the end portion of the handrail member 11, it is possible to prevent the end portion of the handrail member 11 from damaging a load or the like as much as possible.
Further, by providing the handrail support means 20 so as to support the end portion of the handrail member 11 in the longitudinal direction, it is possible to prevent the luggage or the like from being caught as much as possible.

In addition, according to this embodiment, although the screw contact surface 23a was demonstrated as what is comprised by the bottom face of the recessed part 23, the recessed part 23 does not necessarily need to be formed. For example, when the screw insertion hole 24 is formed so as to communicate between the inside and the outside of the support main body 22, the screw contact surface 23 a is formed on the periphery of the opening edge of the screw insertion hole 24. It is formed in a predetermined area on the outer peripheral surface.

Moreover, although demonstrated as what provides the decorative cover 50, the decorative cover 50 may be abbreviate | omitted.
Further, the handrail side bracket 30 has been described as being almost entirely fitted to the support main body portion 22, but the handrail side bracket 30 may be partly fitted to the support main body portion 22.
