Abstract

<P>PROBLEM TO BE SOLVED: To provide a handrail which allows a non-slip irregularity pattern to be exposed, only when it is necessary. <P>SOLUTION: The handrail consists of a wire rod 2 and a cover layer 3, formed of an elastically deformable cushioning material superposed on the outside of the wire rod. Therefore when the user does not touch the cover layer 3, an outer surface 3a of the cover layer 3 exhibits a smooth appearance, but when the cushioning material of the cover layer 3 is compressively deformed due to the touch of the user, the anti-skid irregularity pattern B emerges to the outer surface 3a of the cover layer 3, due to the relief of the wire rod 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention relates to a handrail used by being fixed to a wall surface of a bathroom or a toilet, for example.
Specifically, a wire and a synthetic resin coating layer are coated on the outer periphery of a core made of a metal pipe or the like, and an uneven pattern for preventing slippage is formed on the surface of the coating layer by partial bulging by this wire. Regarding sliding.

Conventionally, as this kind of handrail, a synthetic resin coating layer formed around a metal pipe is composed of an inner skin layer and an outer skin layer, and a plurality of wires are provided between the inner skin layer and the outer skin layer. No matter which direction the grip bar is gripped, no slippage occurs by interposing it in a spiral form and expanding the grid pattern ridges from the surface of the outer skin layer of the coating layer by interposing these wires. Even if the surface of the grip bar or the hand is wet, it can be securely gripped with a stable grip.For example, even when it is used for assistance when going into and out of the bathtub, it is possible to leave the body with peace of mind Yes (see, for example, Patent Document 1).
Further, the grip bar is formed by injecting air into a synthetic resin tube of a covering layer composed of an inner skin layer and an outer skin layer in which the wire is sealed with a resin, increasing its inner diameter, and a core material in the tube. A metal pipe is inserted and joined together, and the whole is cut to a predetermined length to obtain a grip bar as a part.

Japanese Patent No. 3402557 (pages 1 to 3, FIGS. 1 to 4)

However, in such a conventional handrail, although the surface has an uneven pattern for preventing slipping, since the metal surface is covered with a coating layer, the surface of the handrail is hard and easy to slide, and it is not easy to fall down due to lack of gripping. As a result, accidents such as injuries may occur and it is dangerous, and the uneven surface pattern for preventing slippage is always exposed on the surface of the coating layer. Since the dirt in the dents is difficult to clean, there is a problem that the appearance of the entire surface is significantly deteriorated in a short period of time and is unclean.
Especially when the handrail is fixed in a place with high humidity such as a bathroom, water accumulates in the above-mentioned recessed portion, and the water accumulated on this surface makes the hand more slippery and falls due to failure to grasp. There was a problem that the incidence of accidents increased.
By the way, depending on the installation location, the handrail is not only installed horizontally or nearly horizontally, but also installed vertically or nearly vertically, for example, especially when installed vertically. For the reasons described above, slipping becomes even easier and the accident rate increases.
In addition, since the pipe is inserted into the coating layer expanded by the injection of air and joined together, this expanded coating layer will be deformed even if the coating layer made of synthetic resin expands or deforms even after a long period of use. A gap is created between the pipe and the pipe, and if the user squeezes the loose coating layer and applies a load such as weight, only the coating layer rotates and falls over the pipe that is supported so that it cannot rotate. There was a problem that could cause accidents.
In particular, when the handrail is fixed in a highly humid place such as a bathroom, moisture enters the gap between the loose coating layer and the pipe, and the coating layer is more likely to rotate, resulting in a high accident rate. Become.
Furthermore, the operation of inserting the pipe into the coating layer that has been expanded by injecting air can be carried out when the length of the coating layer and the pipe is several meters, There is a problem that the pipe insertion devices are each increased in size and difficult to insert.

The invention according to the first aspect of the present invention aims to expose the uneven pattern for preventing slipping only when necessary.
The invention described in claim 2 is intended to simplify the overall structure in addition to the object of the invention described in claim 1.
In addition to the object of the invention described in claim 2, the invention described in claim 3 aims to prevent the coating layer from spinning around the core material.

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is characterized in that an elastically deformable cushioning material is laminated as a coating layer 3 on the outside of the wire 2 and the coating layer 3 made of this cushioning material is outside. Only when the surface 3a is formed in a smooth shape and the cushioning material of the covering layer 3 is compressed and deformed, the non-slip uneven pattern B appears on the outer surface 3a of the covering layer 3 by the bulging by the wire 2. It is characterized by the fact that it has been allowed to.
The invention described in claim 2 is characterized in that a configuration in which the wire 2 is directly attached to the outer peripheral surface 1a of the core material 1 is added to the configuration of the invention described in claim 1.
According to a third aspect of the present invention, in the configuration of the second aspect, the outer surface of the wire 2 is coated with an adhesive 2a, or the wire 2 is formed with an adhesive, and the core is formed by these adhesives 2a. A configuration in which the outer peripheral surface 1a of the material 1 and the inner surface 3b of the coating layer 3 are bonded and fixed is added.

As described above, according to the first aspect of the present invention, the coating layer 3 made of an elastically deformable cushioning material is laminated on the outside of the wire 2 so that the user does not contact the coating layer 3. Sometimes, the outer surface 3a of the coating layer 3 has a smooth shape, and when the cushioning material of the coating layer 3 is compressed and deformed by the user's contact, the outer surface of the coating layer 3 is bulged by the wire 2. An uneven pattern B for preventing slipping appears on the surface 3a.
Therefore, the anti-slip uneven pattern B can be exposed only when necessary.
As a result, the handrail surface is hard and slippery, and has superior cushioning and heat insulation properties compared to conventional ones where the anti-slip uneven pattern is always exposed on the surface of the coating layer, and the handrail has a high humidity such as a bathroom. Even if it is fixed in a safe place, moisture does not accumulate on the surface of the handrail, and it can reduce accidents such as falls and injuries due to failure to grip, and it can be used with peace of mind, especially for elderly people with weak grip, disabled people, sick people, etc. For example, even if dust or scale adheres to the surface of the handrail, it can be easily cleaned, and the appearance of the entire surface can be maintained in a good condition for a long period of time.
Furthermore, because of its superior cushioning properties, it has a buffering effect even if it hits a person, so it is safe even for elderly people, disabled people, sick people, etc., and it has excellent heat insulation properties, so there is no cold when grasped.
Moreover, even if the handrail is installed vertically or nearly vertically, accidents such as falls and injuries due to the difficulty of gripping can be reliably reduced.

In addition to the effect of the invention of claim 1, the invention of claim 2 is provided between the outer peripheral surface 1 a of the core material 1 and the wire 2 by directly attaching the wire 2 to the outer peripheral surface 1 a of the core material 1. I don't need the endothelial layer.
Therefore, the entire structure can be simplified.

In addition to the effect of the invention of claim 2, the invention of claim 3 is an adhesive 2a that covers the outer surface of the wire 2 or an adhesive that forms the wire 2, and covers the outer peripheral surface 1a of the core 1 By covering and fixing the inner surface 3 b of the layer 3, the coating layer 3 is non-rotatably bonded to the core material 1.
Accordingly, it is possible to prevent the coating layer 3 from spinning around the core material 1.
As a result, there is no gap between the covering layer and the core material, compared to the conventional one in which the pipe is inserted into the covering layer expanded by injecting air and joined together. Even if it is fixed in a high-humidity location such as, it is safe because it can completely prevent accidents such as a fall due to the rotation of the coating layer with respect to the core material that cannot rotate.
In addition, even long objects with a handrail length of several meters do not need to insert a core material into the coating layer one by one. Cost can be greatly reduced.

  As shown in FIGS. 1 to 3, the handrail A of the present invention has a wire 2 attached directly to the outer peripheral surface 1a of a core 1 made of a metal pipe or the like as a grip bar A1, or made of a synthetic resin. A wire 2 is attached across an endothelial layer (not shown), and a coating layer 3 made of an elastically deformable cushioning material is laminated on the outside of the wire 2 so that the coating layer 3 made of the cushioning material is formed. In a non-contact state where the user's hand H does not come into contact with the surface 3a, the outer surface 3a of the coating layer 3 has a smooth shape, and the buffer material of the coating layer 3 is compressed and deformed by contact with the user's hand H or the like. When this is done, the anti-slip uneven pattern B emerges from the outer surface 3a of the covering layer 3 by the bulging of the wire 2.

In the illustrated example, a pair of holders A2 and A2 are attached to both ends of the grip bar A1, respectively, and these holders A2 and A2 are attached to the wall surface by fixing means (not shown) such as screws, for example. The case where the bar A1 is clamped and fixed is shown.
Embodiments of the present invention will be described below with reference to the drawings.

  In the first embodiment, as shown in FIGS. 1A and 1B, a plurality of wire rods 2 are respectively attached to an outer peripheral surface 1a of a core material 1 made of a metal round pipe excellent in corrosion resistance such as stainless steel. A lattice pattern B1 is formed as a non-slip uneven pattern B on the surface of the grip bar A1 by being spirally wound in the direction and directly attached.

  The wire 2 is, for example, a hard synthetic resin wire, or the outer surface of a synthetic fiber, monofilament, or metal wire is coated with an adhesive 2a that solidifies upon cooling, such as hot melt, and exhibits an adhesive force. The adhesive layer is formed, or the wire 2 itself is linearly formed with an adhesive such as hot melt, and the outer peripheral surface 1a of the core 1 and the coating layer described later by these adhesives 2a 3 is bonded and fixed to the inner surface 3b via the wire 2.

The covering layer 3 is formed into a cylindrical shape using, for example, a foam material such as sponge or a soft synthetic resin that can be elastically deformed, and the outer surface 3a has a smooth periphery without being affected by the shape of the inner surface 3b. It is formed into a surface shape.
Further, when the coating layer 3 is formed with a porous material having a large number of small holes on its surface, such as a sponge, the surface is covered with a waterproof layer (not shown) so that moisture or the like does not penetrate inside. It is necessary to.

  An example of a method for manufacturing such a grip bar A1 will be described. The core material 1 is transported at a constant speed along a transport path (not shown), and the outer peripheral surface 1a of the core material 1 fed at a constant speed. The wire 2 continuously extruded from the extrusion molding machine is wound, or the wire 2 is wound by a knitting machine (not shown), and the elastically deformable soft synthetic resin which is heated and melted outside the wire 2 Is continuously extruded into a cylindrical shape in a molten state, whereby the coating layer 3 is extruded on the wire 2, and the adhesive 2 a on the outer surface of the wire 2 is heated and melted by the heat to integrate them.

Next, the operation of the handrail A will be described.
When the user does not hold the grip bar A1 with the hand H or the like and is in a non-contact state with the surface 3a of the covering layer 3, the outer surface of the covering layer 3 is shown in FIG. 3a has a smooth cylindrical shape, and the uneven pattern B for preventing slipping does not appear on the surface of the grip bar A1.
Accordingly, it is possible to prevent moisture and the like from accumulating because there is no recessed portion on the surface of the grip bar A1.

Further, when the cushioning material of the coating layer 3 is compressed and deformed by contact such as the user holding it with a hand H, the outer surface 3a of the coating layer 3 is bulged by the wire 2 as shown in FIG. The uneven pattern B for preventing slipping appears.
As a result, the uneven pattern B for preventing slipping can be exposed only when necessary.

Furthermore, in order to adhere and fix the outer peripheral surface 1a of the core material 1 and the inner surface 3b of the coating layer 3 with the adhesive 2a covering the outer surface of the wire 2 or the adhesive forming the wire 2, the core material 1 On the other hand, the coating layer 3 is non-rotatably bonded.
As a result, there is an advantage that the coating layer 3 can be prevented from spinning around the core material 1.

In Example 1, the wire 2 was directly attached to the outer peripheral surface 1a of the core material 1. However, the present invention is not limited to this, and a synthetic resin endothelial layer (not shown) is provided on the outer peripheral surface 1a of the core material 1. The wire 2 may be attached to sandwich the wire.
In this case, air is injected into a synthetic resin tube in which the wire 2 is sandwiched between the endothelium layer and the coating layer 3 so as to be integrated, the inner diameter thereof is expanded, and the core is inserted into the tube. A grip bar can be obtained as a part by inserting a metal pipe as a material, joining them together, and cutting the whole into a predetermined length.

  In the second embodiment, as shown in FIGS. 2 (a) and 2 (b), one or more wire rods 2 are spirally wound around the outer peripheral surface 1a of the core member 1 so as to be appropriately spaced in the axial direction. Unlike the first embodiment shown in FIGS. 1 (a) and 1 (b), the configuration in which the spiral pattern B2 is formed on the surface of the grip bar A1 as the uneven pattern B for preventing slipping is different from that of the first embodiment. The configuration is the same as that of the first embodiment.

  In this third embodiment, as shown in FIGS. 3A and 3B, a plurality of wires 2 extending in the axial direction along the outer peripheral surface 1a of the core material 1 are attached at appropriate intervals in the circumferential direction. Alternatively, the configuration in which the straight pattern B3 is formed as the uneven pattern B for preventing slipping on the surface of the grip bar A1 by attaching only one is the same as the embodiment 1 shown in FIGS. 1 (a) and 1 (b). The other configurations are the same as those of the first embodiment.

Accordingly, the grip bars A1 of the second and third embodiments are also in a non-contact state where the user does not grip the surface 3a of the coating layer 3 with the hand H or the like, similar to the grip bar A1 of the first embodiment described above. As shown in FIGS. 2 (a) and 3 (a), the outer surface 3a of the covering layer 3 has a smooth cylindrical shape, and the uneven pattern B for preventing slipping does not appear on the surface of the grip bar A1. When the cushioning material of the coating layer 3 is compressed and deformed by contact such as the user holding it with his hand H, the coating layer 3 is bulged by the wire 2 as shown in FIGS. 2 (b) and 3 (b). A non-slip uneven pattern B appears on the outer surface 3a.
As a result, the uneven pattern B for preventing slipping can be exposed only when necessary.

  In the illustrated example, the holders A2 and A2 provided at both ends of the grip bar A1 are attached to the wall surface. However, the present invention is not limited to this, and both ends of the core 1 made of, for example, a metal pipe are substantially U-shaped. Other structures may be employed, such as bending to a wall and attaching these bent portions to a wall surface by a wall mounting means.

  Furthermore, although the case where the said core material 1 was a metal round pipe was shown, it is not limited to this, The hollow pipe and solid round shape which were shape | molded with the metal and other hard materials instead of this round pipe A rod may be used, or a pipe or a rod shaped like a polygon or an ellipse such as a triangle or quadrangle in cross section may be used.

Further, the anti-slip uneven pattern B formed on the surface of the grip bar A1 is not limited to the illustrated lattice pattern B1, spiral pattern B2, or straight line pattern B3, and can be formed by winding the wire 2. Any other pattern may be used.
Furthermore, although the case where the coating layer 3 has a single-layer structure has been shown, the present invention is not limited to this, and may have a two-layer structure or a structure of three or more layers.
