Description

  The present invention relates to an end cap for a handrail attached to a terminal portion of a handrail.

A handrail is an auxiliary facility that is attached to a wall or the like so that mainly elderly people and sick people can walk stably. If this handrail is straight up to its end, when you try to catch it on the handrail, the cuff will be caught by the end of the handrail and it will be out of hand, or it will be suddenly pulled back at the cuff and fall down. There are things to do. The cuffs may also be torn. For this reason, it is preferable that the handrail end is bent, and a handrail end cap is attached to the handrail end so that the end face of the handrail end cap faces downward or toward the wall. It is common.
However, the handrail end cap may have to be oriented diagonally rather than down or on the wall.

For this reason, there exists invention which concerns on patent 4135930 as an end cap for handrails which can be attached to the terminal part of a handrail also in the diagonal direction.
The invention according to this patent No. 4135930 is “a handrail for connecting an end cap bent at an intermediate portion to an end portion of a hollow handrail via a connecting metal fitting, on the side facing the end portion of the handrail of the end cap. A polygonal concave portion excluding a quadrangle is formed in the end surface of the first metal fitting, and a first fitting portion having a polygonal cross section that fits into the concave portion is formed in one end portion of the connecting fitting, and the other end The part is formed with a second fitting part that fits in the hollow part of the handrail protruding from the biased position of the end face of the first fitting part with grooves on the upper and lower parts, The first fitting portion is penetrated from the fitting portion side, and a screw is screwed into the bottom portion of the concave portion to be fixed, and from the lower side of the hollow portion to the upper groove from the lower groove of the second fitting portion. A handrail characterized in that another screw is screwed in and fixed. ].

The handrail according to Japanese Patent No. 4135930 is “a handrail that connects an end cap bent at an intermediate portion to an end portion of a hollow handrail through a connecting metal fitting”, and is therefore a general-purpose product such as solid wood or laminated wood. It cannot be applied to a certain solid handrail, requires a connecting metal fitting, etc., and the handrail needs to use a dedicated product for fitting the connecting metal fitting.
A handrail end cap corresponding to a handrail, which is a general-purpose product, is formed by integrally forming an insertion portion that is inserted into a terminal portion of a handrail and a curved portion that is curved with respect to the insertion portion. A screw opening is formed in the peripheral surface of the insertion portion. The handrail end cap is fixed to the handrail by screwing the tapping screw into the handrail inserted into the insertion portion through the screw opening.

  The handrail end cap 100A according to the first embodiment of the present invention includes an end member 110A into which the end portion 210 of the handrail main body 200 is inserted, and a curved end cap main body connected to the end member 110A. 120A, and a bolt 130A for connecting the end cap main body 120A and the end member 110A, and a screw 140A for fixing the handrail main body 200 having the end portion 210 inserted in the end member 110A. A screw opening 115A is provided, a convex portion 112A is provided on the side facing the side where the handrail main body 200 is inserted, and a concave portion 123A in which the convex portion 112A is inserted is provided in the end cap main body portion 120A. Each of the bolts 130A includes an end member 110A and an end cap body 120A. While maintaining the forming state, the convex portion 112A has a leg portion 131A of the length that can be disengaged from the recess 123A.

  The handrail body 200 is formed in, for example, a wooden columnar shape. Handrail end caps 100 </ b> A are attached to the left and right end portions 210 of the handrail main body 200.

The end member 110A constituting the handrail end cap 100A is formed in a bottomed cylindrical shape into which the terminal portion 210 of the handrail main body 200 is fitted. A convex portion 112A that protrudes outward is formed at the center of the bottom surface portion 111A of the end member 110A, that is, the side opposite to the side on which the handrail main body 200 is inserted. A bolt through hole 113A through which a later-described bolt 130A passes is formed at the center of the convex portion 112A.
As shown in FIG. 1, the convex portion 112 </ b> A is formed in a quadrangular prism shape having a square bottom surface.

Further, one screw opening 115A for the screw 140A for fixing the inserted handrail body 200 is provided in the peripheral wall 114A of the end member 110A. The screw 140A is a tapping screw whose head is a flat plate type. Accordingly, the screw opening 115A also has a large diameter on the outside and a small diameter on the inside corresponding to the head of the screw 140A.
Moreover, the screw opening 115A is opened at a position parallel to the surface including one of the side surfaces of the convex portion 112A.

The end member 110A is formed with a tapered surface 116A toward the inserted handrail body 200 at the edge of the peripheral wall 114A so as not to form a large step with the inserted handrail body 200. ing.
The end member 110A is a portion corresponding to the insertion portion in the handrail end cap corresponding to the handrail which is a general-purpose product described in the background art.

On the other hand, an end cap main body 120A that constitutes the handrail end cap 100A together with the end member 110A includes an attachment surface 121A that faces the end member 110A, and an end portion 122A that is curved in a direction orthogonal to the attachment surface 121A. And have. The mounting surface 121A is formed with a concave portion 123A into which the convex portion 112A is inserted. The recess 123A is a quadrangular recess corresponding to the protrusion 112A, and a female screw 124A into which a bolt 130A described later is screwed is formed at the center.
The recess 123A is configured such that each side is vertical or horizontal in a state where the end cap main body 120A stands with the end 122A as a bottom surface.

The end portion 122A is formed in a cylindrical shape, and four claw portions 126A are formed at intervals of 90 ° on the inner peripheral surface 125A. The claw portion 126A locks a disk-shaped cap 127A for closing the end portion 122A.
The end cap main body 120A is a portion corresponding to the curved portion of the handrail end cap corresponding to the handrail which is a general-purpose product described in the background art.

  By the way, the protrusion dimension of the convex part 112A and the concave dimension of the concave part 123A are set slightly smaller. This is because when the convex portion 112A is inserted into the concave portion 123A, the mounting surface 121A of the end cap main body portion 120A and the bottom surface portion 111A of the end member 110A are securely brought into close contact with each other.

The bolt 130A connects the end member 110A and the end cap main body 120A. Even if the leg portion 131A is still screwed into the female screw 124A, the convex portion 112A has the concave portion 123A. It is set to a length that can be removed. Of course, if the bolt 130A is completely screwed into the female screw 124A, the mounting surface 121A of the end cap main body 120A and the bottom surface portion 111A of the end member 110A are in close contact with each other.
However, if the bolt 130A is loosened from this state, the bolt 130A is screwed into the female screw 124A of the end cap main body 120A via the bolt through hole 113A of the end member 110A, but the convex portion 112A is recessed. 123A can be removed. In this state, the end member 110A and the end cap body 120A can rotate around the bolt 130A.

With reference to FIGS. 2 to 4, a procedure for attaching the handrail end cap 100 </ b> A configured in this way to the handrail main body 200 spanned over the column 300 standing on the floor F as shown in FIG. 4 will be described. I will explain. In this case, the end cap main body 120A faces downward.
The handrail main body 200 may already be hung on the column 300, or may be hung on the column 300 after the handrail end cap 100A is attached to the left and right end portions 210.
As shown in FIG. 4, the bolt 130A of the handrail end cap 100A is loosened to a state where it is still screwed but not removed. Then, although the convex portion 112A of the end member 110A is disengaged from the concave portion 123A of the end cap main body portion 120A, the end member 110A and the end cap main body portion 120A are still connected with the bolt 130A.

  In this state, the end cap main body 120A faces downward, and the screw opening 115A of the end member 110A faces downward. This is because the screw opening 115A is opened at a position parallel to the surface including one of the side surfaces of the convex portion 112A, and each side of the concave portion 123A is vertical when the end cap main body portion 120A is the bottom surface of the end portion 122A. Or it is possible because it is configured to be horizontal.

The bolt 130A is tightened from this state, and the end member 110A and the end cap main body 120A are completely connected in a state where the convex portion 112A is inserted into the concave portion 123A as shown in FIG.
With the end cap body portion 120A facing downward, the end portion 210 of the handrail body 200 is inserted into the end member 110A of the handrail end cap 100A. Then, a screw 140A, which is a tapping screw, is screwed into the handrail body 200 from the screw opening 115A. As a result, the screw 140A is positioned on the lower side of the handrail end cap 100A, so that the screw opening 115A and the screw 140A inserted therethrough are not noticeable.

Next, a procedure for attaching the handrail end cap 100A to the handrail main body 200 spanned over the bracket 310 attached to the wall surface W as shown in FIG. 6 will be described with reference to FIGS. To do. In this case, the end cap main body 120A faces the wall surface W, that is, becomes horizontal.
As shown in FIG. 3, the bolt 130A of the handrail end cap 100A is loosened to a state where it is still screwed but not removed. Then, although the convex portion 112A of the end member 110A is disengaged from the concave portion 123A of the end cap main body portion 120A, the end member 110A and the end cap main body portion 120A are still connected with the bolt 130A.

In this state, as shown in FIG. 5, the end cap main body 120A faces the horizontal direction, and the screw opening 115A of the end member 110A faces downward.
The bolt 130A is tightened from this state, and the end member 110A and the end cap main body 120A are completely connected in a state where the convex portion 112A is inserted into the concave portion 123A.
The handrail end cap 100A shown in FIG. 5 is attached to the left end portion 210 of the handrail main body 200 shown in FIG. The handrail end cap 100A attached to the right end portion 210 must be symmetrical to that shown in FIG. That is, the handrail end cap 100A attached to the right end portion 210 is obtained by rotating the end member 110A of the handrail end cap 100A attached to the left end portion 210 by 180 ° around the bolt 130A.

If this kind of conventional handrail end cap is integrated with the end member 110A and the end cap main body 120A, the one attached to the left side of the handrail main body 200 and the one attached to the right side are not the same. However, in this handrail end cap 100A, the end member 110A and the end cap main body 120A are separated from each other. There is a merit that it can cope with things.
Moreover, the handrail end cap 100A attached downward as shown in FIG. 4 and the handrail end cap 100A attached toward the wall surface W as shown in FIG.
In the case of a conventional handrail end cap in which the end member 110A and the end cap main body 120A are integrated, a total of three types are prepared: one for downward, one for left, and one for right. Although there was a necessity, if it is this end cap 100A for handrails, it can respond to all these with one thing.

In the handrail end cap 100A according to the first embodiment described above, the convex portion 112A has a quadrangular prism shape whose bottom surface is square, and the concave portion 123A is a quadrangular recess corresponding to the convex portion 112A.
However, the present invention is not limited to this.
As shown in FIG. 7, the handrail end cap 100B according to the second embodiment of the present invention is connected to the end member 110B into which the terminal portion 210 of the handrail main body 200 is inserted, and to this end member 110B. A curved end cap main body 120B, and a bolt 130B for connecting the end cap main body 120B and the end member 110B, and a handrail main body into which the end portion 210 is inserted into the end member 110B. A screw opening 115B for a screw 140B for fixing 200 is opened, a convex portion 112B is formed on the side facing the side where the handrail main body 200 is inserted, and the convex portion 112B is formed on the end cap main body portion 120B. Recesses 123B to be inserted are respectively formed, and the bolt 130B includes an end member 110B and an end cap book. The convex portion 112B has a leg portion 131B having a length that allows the convex portion 112B to be detached from the concave portion 123B while maintaining the state where the portion 120B is connected, and the convex portion 112B has a regular quadrangular prism shape, and the concave portion 123B It is formed in an eight-pointed star shape.

  The handrail end cap 100B according to the second embodiment is different from the handrail end cap 100A according to the first embodiment in the concave portion 123B, and other points are the same or substantially the same. Detailed description of other points is omitted.

The concave portion 123B of the end cap main body 120B of the handrail end cap 100B according to the second embodiment is formed in a so-called octagonal shape in which two squares of the same size are inclined and overlapped by 45 °. Accordingly, the corners of the recess 123B are shifted at 45 ° intervals around the female screw 124B. Therefore, since the convex portion 112B has a regular quadrangular prism shape, the end member 110B can be attached in eight postures in a state shifted by 45 ° with respect to the end cap main body portion 120B.
In the handrail end cap 100A according to the first embodiment, since both the convex portion 112A and the concave portion 123A have a quadrangular prism shape, they can be attached in four postures shifted by 90 °. .

  With the handrail end cap 100B configured in this way, the attachment direction of the handrail end cap 100B to the terminal portion 210 of the handrail main body 200 becomes more diverse, so that not only the straight handrail main body 200 but also the left and right terminal ends. Even if the portions are not on the same straight line, that is, bent or curved in the middle, the screw opening 115B and the screw 140B inserted therethrough can be made inconspicuous.

Further, as in the handrail end cap 100C according to the third embodiment shown in FIG. 8, the convex portion 112C can be formed into a cylindrical shape, and the concave portion 123C can be formed into a cylindrical recess corresponding to the convex portion 112C. It is.
Thus, if the convex part 112C and the recessed part 123C are not polygonal shape but cylindrical shape, there exists an advantage that the attachment angle to the end cap main-body part 120C of the edge part member 110C can be set more freely.
However, since the convex portion 112C and the concave portion 123C are cylindrical, the handrail body 200 may rotate around the bolt 130C as a central axis.
In the handrail end caps 100A and 100B described above, the handrail body 200 does not rotate around the bolts 130A and 130B as the central axis.

  The handrail end cap 100C according to the third embodiment is different from the handrail end cap 100A according to the first embodiment only in the convex portion 112C and the concave portion 123C, and the other points are the same or substantially the same. Therefore, detailed description of other points is omitted below.

  In the above-described first to third embodiments, the end members 110A, 110B, and 110C have the convex portions 112A, 112B, and 112C, and the concave portions 123A, 123B, and 123C that correspond to the end cap main body portions 120A, 120B, and 120C. Although it is said that each is formed, the opposite, that is, a concave portion may be formed on the end member, and a convex portion corresponding to the end cap main body portion may be formed.

  In the first embodiment, the four claw portions 126A are formed at intervals of 90 ° on the inner peripheral surface 125A of the end portion 122A. However, the end portion 122A is not cylindrical but solid. May be. In that case, there is no claw 126A, and a disc-shaped cap 127A for closing the end portion 122A is not necessary.

In the first embodiment described above, the leg portion 131A of the bolt 130A is long enough to allow the convex portion 112A to be disengaged from the concave portion 123A while maintaining the state where the end member 110A and the end cap main body portion 120A are connected. However, the present invention is not limited to this.
The length of the leg portion may be such that the convex portion 112A cannot be removed from the concave portion 123A unless the bolt is completely removed.
The same applies to the handrail end cap 100B according to the second embodiment and the handrail end cap 100C according to the third embodiment.
