Description

[Detailed Description of the Invention] The present invention relates to a handrail for a room equipped with sanitary appliances, such as a toilet bowl, bathtub, wash basin, etc., which is attached to the sanitary appliances.

Conventionally, there is a handrail described in Japanese Utility Model Publication No. 32-4185, in which one end of a handrail is attached to a wall or floor and a metal fitting is provided to cover the attached part. As shown in FIG. 9, a mounting bracket 54 consisting of a flange portion 53 that abuts a cylindrical portion 51 that fits the end of the handrail 50 and a mounting surface 52 is attached to the handrail 50.
A cover 56 is fixed on the mounting surface 52 with screws 55 and covers the entire mounting bracket 54.
The cover 56 is integrally screwed and fixed to the mounting fitting 54 by screwing the threaded portion 57 into the threaded portion 58 formed on the outer periphery of the cylindrical body portion 51 of the mounting fitting 54. Such a mounting bracket 54 and cover 56
In this structure, when installing the handrail 50, the screws 5 are first attached to the mounting surface 52 together with the handrail 50 that is fitted and fixed to the mounting bracket 54.
5 into the mounting surface 52, the cover 56 must be held in any position on the handrail 50 during this screwing process. However, since the cover 56 is formed to slide around the outer periphery of the handrail 50,
As mentioned above, the cover 56 cannot be temporarily fixed in any position, making the construction work difficult, and if the cover 56 slides on the handrail 50 body, it may damage the handrail 50 body and cause damage to the appearance. There was a problem with the loss of .

This invention was devised to solve the above-mentioned problems caused by the structure of the conventional handrail mounting part, especially the cover that covers the handrail mounting part, and its purpose is to improve the handrail installation work. The purpose is to easily cover the handrail mounting portion with a cover without damaging the outer surface of the handrail body, and to prevent corrosion of the wall surface.

The basic structure of the present invention is that a cover has an insertion hole through which the handrail body is inserted and covers the mounting base of the handrail body, and the bottom surface of the recess has an annular recess for attaching an annular elastic packing on the wall forming the insertion hole. The elastic packing is provided so as to be larger than the inner diameter of the wall forming the insertion hole, and the inner diameter of the elastic packing is smaller than the outer diameter of the handrail body, and when the cover is installed, the elastic pressure of the elastic packing gently presses the outer periphery of the handrail body. This allows the cover to be held stationary on the handrail body.

Hereinafter, referring to the embodiment shown in the attached drawings, the following will describe a toilet bowl that is attached around the toilet bowl, with its base end attached to the floor and wall of the sanitary equipment equipment room in which the toilet bowl is installed as shown in Figure 1. A perspective view of a handrail for a sanitary equipment room according to the present invention installed as a handrail for a physically handicapped person is shown. In the figure, A is a toilet installed on the floor F of the sanitary equipment room, G is a handrail body made of straight or curved stainless steel pipe or brass pipe, and J is T-shaped. 1 is a cover that covers the attachment surface of the handrail main body G on the floor F or wall W, and a side sectional view of the cover 1 is shown in FIG.

The cover 1 is a bowl-shaped cover body 2 that covers the mounting base of the handrail body G that protrudes and is fixed to the mounting surface.
and a cylindrical body 3 that is located on the same axis inside the cover body 2 and forms, together with the cover body 2, an insertion opening for the handrail body and an annular recess that serves as a gasket attachment part.
and an elastic packing 4 having a circular cross section made of rubber or the like and fitted into the annular recess.

Regarding the cover body 2 and the cylindrical body 3, to describe them in more detail, a side sectional view of the cover body 2 is shown in FIG. As shown in the figure, it is formed into a bowl shape with openings of different diameters at both the upper and lower ends, and when the lower large diameter opening 5 is brought into contact with the mounting surface during construction, the handrail body G
The mounting base can be covered. Furthermore, 6 is an upper small-diameter opening, which is bent from the inner peripheral edge of the small-diameter opening 6 toward the mounting surface side, that is, toward the lower large-diameter opening 5 side, and whose end portion extends outside the cover body 2. A flange portion 7 is formed around the entire circumference of the small diameter opening 6 so as to face the small diameter opening 6.

FIG. 4 shows a side sectional view of the cylinder 3.
The cylindrical body 3 has a large diameter portion 8 having a required axial length and having an inner diameter slightly larger than the outer peripheral end diameter of the lower end of the flange portion 7 of the cover body 2, and a diameter reduced by a required amount from the lower end of the large diameter portion 8. A stepped portion 9 is formed toward the center so that
and a small diameter part 10 which is bent downward from the inner peripheral edge of the stepped part 9 and has a substantially arcuate cross section, and the minimum inner diameter of the small diameter part 10 is equal to the small diameter opening 6 of the cover main body 2.
It is formed so that it is approximately equal to or slightly larger than the inner diameter of. Further, numeral 11 denotes a plurality of protrusions (three in this embodiment) provided on the upper side of the large diameter portion 8, which protrude inwardly by caulking toward the center of the cylindrical body 3. Its position is the 6th
As shown in the figure, when the cover body 2 and the cylinder 3 are connected, the upper end surface 8a of the large diameter part 8 of the cylinder 3 is connected to the cover body 2.
Press fit so as to contact the back surface 2a of the top surface of the
At this time, the protrusion 11 is provided at a distance from the upper end surface 8a of the large diameter portion 8 such that it can engage with the outer edge upper surface portion 7a of the flange portion 7 of the cover body 2. Like the cover body 2, this cylindrical body 3 is manufactured by press-forming a stainless steel plate or the like.
The caulking of the protrusion 11 can also be performed at the same time as the press forming.

To form the cover 1 by combining the cover body 2, the cylinder 3, and the annular elastic packing 4,
First, the upper end opening of the large diameter part 8 of the cylinder 3 is connected to the cover main body 2.
The outer end portions 7b of the flange portions 7 are arranged so as to fit together, and the cylindrical body 3 is press-fitted from below. During this press-fitting process, the protrusion 11 provided on the large diameter portion 8 is locked to the outer end 7b of the flange 7 of the cover main body 2, and the press-fitting progress is obstructed. 3
Since the protrusion 11 is formed by caulking from the outside, the inner peripheral wall surface of the protrusion 11 can be formed into a smooth convex surface in the vertical direction, that is, in the press-fitting direction. Projection 11 of large diameter portion 8
Due to elastic deformation on the upper side of the forming part, the protrusion 11
passes over the outer end 7b of the flange 7, resulting in a connected state as shown in FIG. In the coupled state shown in the figure, as described above, the upper end surface 8a of the large diameter portion 8 is
is in contact with the back surface 2a of the upper surface portion of the cover main body 2, and the protrusion 11 is in contact with the outer edge upper surface portion 7a of the flange portion 7.
It is locked to. Therefore, since the protrusion 11 is engaged by the flange 7, the cylinder 3 does not fall off from the cover body 2, and the upper end surface 8a of the cylinder 3 abuts unevenly on the back surface 2a of the cover body 2. Since the protrusion 11 and the flange 7 are in contact with each other without being in contact with each other, the locking force between the protrusion 11 and the flange 7 makes the connection more stable. Since it can be aligned with the center, the tubular body can be inserted easily.

By coupling the cover main body 2 and the cylinder 3, the opening from the small diameter opening 6 to the small diameter part 10 can be formed into the insertion opening I of the handrail main body G. An annular recess R having a bottom surface of the recess in the radial direction that is larger than the inner diameter of the insertion hole I is formed by the inner circumferential surface 8b below the protrusion 11 of No. 8 and the stepped portion 9.
A cover 1 is formed by attaching an elastic packing 4 therein.

When this elastic packing 4 is installed, its inner circumferential diameter is smaller than the inner diameter of the insertion hole I of the cover 1 by a required amount,
Moreover, it may be formed to be smaller than the outer diameter of the handrail body G so that the outer peripheral surface of the tubular body can be elastically clamped.
In addition, in the above joining procedure, the elastic packing 4 was attached after the cover body 2 and the cylinder 3 were combined, but it was placed on the stepped part 9 of the cylinder 3 and the cylinder 3 and the elastic packing 4 were attached to the cover at the same time. Needless to say, it may be combined with the main body 1.

Regarding an installation example of the handrail main body G equipped with the cover 1 having the above configuration, the first installation example is shown in FIG. The mounting portion provided at the end of the handrail body G is abutted and fixed on the surface of a wall or floor, and the entire mounting portion is covered with the cover 1. In the figure, reference numeral 12 denotes a flange-shaped attachment part that is integrally attached to the end of the handrail body G by welding, and the attachment part 12 fits the end of the handrail body G by the required amount. It is formed of a cylindrical body part 13 and a flange part 14 formed to extend in the outer radial direction from the lower end of the cylindrical body part 13. An opening 15 is bored through which the opening 16 is inserted.

To describe the construction procedure of the construction example shown in FIG. 7, first, the cover 1 is fitted onto the handrail body G and held at a position where it does not interfere with the installation of the screws 16. This is because the elastic gasket 4 of the cover 1 elastically and loosely presses the outer surface of the handrail body G with its elastic force, so the cover 1 is moved to any position along the handrail body G due to the frictional force based on the pressing force. The cover 1 can be held stationary, and there is no need to support the cover 1 from the outside by hand. Next, the lower surface of the flange portion 14 of the mounting portion 12 is brought into contact with the mounting surface 20 such as a wall or floor surface, and the required screws 16 are inserted through the opening 15 of the flange portion 14 and screwed into the inside of the mounting surface 20. The mounting portion 12 is fixed to the mounting surface 20, and therefore the handrail main body G is also fixed to the mounting surface 20 in the same manner. In the above installation, screws were used to secure the mounting part 12, but when the force applied to a large-diameter handrail or the handrail body becomes large, it may be necessary to connect an anchor pin and an anchor bolt to increase the installation strength. It is best to attach it with an anchor bolt using the commonly used expansion shield method.

When the handrail main body G is fixed to the mounting surface 20 via the mounting part 12 as described above, the handrail main body G is placed in a position that does not interfere with the installation work as described above.
The cover 1 held at an arbitrary position is moved to the mounting surface 20. During this movement, the inner peripheral wall of the elastic packing 4 attached to the cover 1 slides into contact with the outer surface of the handrail main body G, but since the elastic packing is soft and has elasticity, the outer surface of the handrail main body G No damage to the outer surface. Therefore, the lower end surface of the large diameter opening 5 of the cover body 2 of the cover 1 comes into contact with the mounting surface 20, and the mounting portion 12
The cover 1 covers the entire handrail body G, and the mounting surface portion of the handrail body G is completely covered without exposing the mounting portion 12, screws 16, etc.

By covering the mounting surface with the cover 1 as described above, water can be prevented from adhering to the outer surface of the handrail main body G in indoor sanitary equipment facilities where water is often used, and especially in the case of a vertical handrail, water can be transmitted along the outer surface. The water flows down and tries to reach the mounting surface 20, but an elastic packing 4 is interposed between the outer surface of the handrail main body G and the insertion hole I of the cover 1 and acts as a seal, and the water flows down due to the sealing action. Water is blocked and does not flow into the mounting surface 20 covered with the cover 1.

Therefore, since water can be prevented from entering the inside of the wall surface of the mounting surface 20, corrosion inside the wall surface can be prevented, and rusting of the fixing screws 16 can be suppressed, preventing the screws 16 from breaking or the installation strength being deteriorated. There is no.

Next, FIG. 8 shows an example of the installation construction shown in FIG. 22, the lower surface of the flange portion 14 of the mounting portion 12 is brought into contact with the lower surface of the flange portion 14 of the mounting portion 12, and the handrail main body G is fixed in the recessed portion 21 via the mounting portion 12 with the screws 16 in the same manner as in the first construction example, and then 21 is filled with white cement, mortar, etc., and the flange part 14 and above of the recessed part 21 are made into a filling layer 23, and the filling layer 2
This method is called a "embedding method" in which the upper surface of the mounting surface 20 is molded flush with the mounting surface 20.

Also in this second construction example, the method of attaching the mounting portion 12 and handling of the cover 1 are the same as in the first construction example, and detailed explanations will be omitted.

As described above, the handrail for a sanitary appliance room according to the present invention has the following effects due to its configuration.

(1) An annular recess is formed on the inner wall of the insertion opening of the cover, and an annular elastic packing whose inner diameter when installed is smaller than the outside diameter of the handrail body is fitted into the annular recess. Since the cover can be held stationary at any position along the handrail body due to its elastic force, the cover does not get in the way when the handrail body is attached to the mounting surface, making the work of attaching the handrail body easy.

(2) Even when the cover is slid along the handrail body, the elastic packing only comes into contact with the outside surface of the handrail body, so the sliding movement does not damage the outside surface of the handrail body, and the handrail body can be easily moved. It does not damage the appearance of the main body.

(3) Since the cover can be held stationary at any position on the handrail body due to (1) above, there is no need to provide a threaded part or an engaging part on the handrail body to hold the cover even in a position that covers the mounting surface. Therefore, it is easy to manufacture the handrail body.

(4) Even if water tries to reach the mounting surface through the handrail body, the elastic gasket acts as a sealing material, so water will not enter the mounting surface covered by the cover and the inside of the mounting wall will not corrode. There is no.
Therefore, it is particularly effective as a handrail for sanitary equipment equipment rooms.

(5) Since the mounting part is entirely covered with a cover, the mounting screws are not exposed, the screws, etc. cannot be removed, and the handrail itself is not stolen.
