Description

The present invention relates to a continuous handrail.

As shown in Patent Documents 1 and 2, there is a type of continuous handrail in which the handrail body has a base section that is attached to the wall surface, a grip section that is set higher than the base section and away from the wall surface and is grasped by the user, and an overhang section that connects the lower ends of the base section and grip section. In this type of continuous handrail, the wall surface, base section, overhang section, and grip section define a specified space that is open upward. This specified space is also open in the lateral direction of the handrail body.

It is common for the lateral ends of a handrail body to be covered with end members to improve the appearance of the lateral ends. Patent Document 1 discloses an end member that has approximately the same cross-sectional shape as the handrail body and has an attached rib that covers the outer periphery of the lateral end of the handrail body. Patent Document 2 also discloses an end member that has a continuous wall that covers the outer periphery of the lateral end of the handrail body and a first end face that separates the lateral end of a specified space.

JP 2008-19582 A Patent No. 6271880

In a continuous handrail, if a predetermined space is left open laterally on the handrail body, as in Patent Document 1, for example, the gripping portion located at the lateral end of the handrail body can be used as a kind of hook for hanging items such as baggage (for example, shoulder straps attached to baggage), making it easy for the handrail to be used for purposes other than its original purpose. In particular, if the item hung on the gripping portion is heavy, it could end up deforming the gripping portion.

On the other hand, as described in Patent Document 2, a configuration in which the specified space is covered laterally by an end member makes it difficult to hook an object onto the grip located at the lateral end of the handrail body, and is therefore preferable in that it can only be used for the handrail's intended purpose.

In the device described in Patent Document 2, the end member separates the lateral end of a predetermined space with its first end face, while the side of the end member protrudes outward in the lateral direction. Therefore, depending on the part of the user's fingers gripping the handle that is located within the predetermined space, the end member is susceptible to external forces in a direction that causes it to come out of the handrail body (disengage from the engagement). Repeated external forces in this direction can deform or damage the continuous wall or fixing protrusions of the end member, causing the first end face of the end member to partially separate from the lateral end face of the handrail body, creating a gap between the grip and the end member. Furthermore, the lateral end of the handrail body is susceptible to large external forces in a direction away from the user gripping the handle, toward the wall surface, and may even become deformed.

The present invention was made in consideration of the above circumstances, and its purpose is to provide a continuous handrail that improves the connection strength between the end members and the lateral ends of the handrail body while ensuring the strength of the end members, and also prevents deformation of the lateral ends of the handrail body.

In order to achieve the above object, the present invention adopts the following solution method:
The handrail comprises a handrail body attached to a wall surface and extending laterally, and an end member attached to the lateral end of the handrail body,
The handrail main body has a base portion fixed to the wall surface, a grip portion that is located farther from the wall surface than the base portion and higher than the base portion and is grasped by a user, and an overhang portion that connects the base portion and the grip portion,
The wall surface, the base portion, the protruding portion, and the gripping portion partition a predetermined space portion that is open upward,
The end member has a main body wall portion having a shape that covers the handrail main body and the predetermined space from the side, a fitting recess formed in the main body wall portion into which the lateral end of the handrail main body is fitted, and a fitting protrusion that protrudes from the main body wall portion into the predetermined space portion and has a shape that corresponds to the cross-sectional shape of the predetermined space portion,
the fitting protrusion is fitted across the protruding portion and the gripping portion and is in close proximity to or in contact with the wall surface;
This is how it is done.

According to the above solution, the mating protrusion formed on the end member is a member with a shape corresponding to the cross-sectional shape of the specified space. Furthermore, because the mating protrusion is mated across the protruding portion and grip portion of the handrail body, the connection strength between the handrail body and the end member is greatly improved. This improves the ability to prevent deformation and damage to the portion of the end member that is fixed to the handrail body, preventing gaps from forming between the end member and the handrail body. Furthermore, the lateral ends of the handrail body are susceptible to large external forces exerted toward the wall by a user gripping the grip portion. However, because the mating protrusion is close to or in contact with the wall, the mating protrusion absorbs this large external force, preventing the lateral ends of the handrail body from significantly deforming toward the wall. Of course, the main body wall portion, mating recess, and mating protrusion of the end member make it difficult to hook an object at the grip portion at the lateral end of the handrail body.

In the present invention, the following first aspect can be adopted.
The end member has a flange portion extending laterally from the outer peripheral edge portion of the main body wall portion toward the handrail main body side,
The flange portion has an upper flange portion extending from near the upper end of the grip portion toward the wall surface, a lower flange portion extending along the lower surfaces of the base portion and the overhang portion, and a connecting flange portion connecting the upper flange portion and the lower flange portion,
The fitting protrusion has the upper flange portion, a vertical surface portion extending downward from the edge of the upper flange portion on the handrail main body side so as to close the predetermined space portion, and a connecting surface portion connecting the peripheral edge portion of the vertical surface portion to the main body wall portion so as to be along the base portion, the overhanging portion, and the grip portion,
The fitting recess is formed along the lower flange portion, the connecting flange portion, and the connecting surface portion.
According to the above aspect, a specific structure of the fitting protrusion and a specific structure of the fitting recess are provided.

In the present invention, the following second aspect can be adopted.
The fitting protrusion may have a hollow structure having a cavity surrounded by the main body wall portion, the upper flange portion, the vertical surface portion, and the connecting surface portion. This aspect is preferable in terms of reducing the weight and material used of the fitting protrusion, which is a large component.

The present invention can adopt the following third aspect.
The cross-sectional shape of the grip portion has a bulging portion that bulges out toward the wall surface side, and the fingertips of a hand can fit under the bulging portion,
The upper surface of the fitting protrusion is positioned at a height equal to or higher than the lower end of the bulging portion.
According to the above aspect, the gripping portion can be firmly grasped with the fingers by positioning the fingertips in the space below the bulge. Furthermore, since the upper surface of the fitting protrusion is set to a height equal to or higher than the lower end position of the bulge, it is not possible to pass an object through the space below the bulge, which is preferable in terms of preventing the bulge from being used to hang objects.

The present invention can adopt the following fourth aspect.
When the continuous handrail is attached to the wall surface, the outer surface shape of the end member is designed to have no protrusions or steps that can be used to hang objects.
According to the above aspect, it is possible to further prevent objects from getting caught on the end members.

The present invention can adopt the following fifth aspect. That is, the lower flange portion, the connecting flange portion, and the connecting surface portion can be bonded to the outer peripheral surface of the lateral end portion of the handrail main body with an adhesive. According to the above aspect, almost the entire outer peripheral surface of the lateral end portion of the handrail main body is bonded to the end member with an adhesive, which is preferable for more sufficiently increasing the connection strength between the handrail main body and the end member.

The present invention can adopt the following sixth aspect.
The upper surface of the end member can be a flat surface that extends from the upper end of the gripping portion toward the wall surface at a position slightly higher than the upper end of the gripping portion. This aspect is preferable in that it makes it more difficult for objects to get caught on the lateral ends of the continuous handrail.

The present invention can adopt the following seventh aspect.
The handrail body is hollow and has a hollow rib structure in which the interior is divided into a plurality of cavities by ribs, and the cavities are formed in the grip portion and the base portion, respectively.
The body wall of the end member is formed with a first connecting protrusion that protrudes into the hollow portion formed in the grip portion, and a second connecting protrusion that protrudes into the hollow portion formed in the base portion,
the first connecting protrusion is adhered to the grip portion by an adhesive;
The second connecting protrusion is fastened together with the base portion to the wall surface by a fixing screw.
According to the above aspect, the handrail main body and the end member can be more firmly connected to each other.

This invention utilizes a mating protrusion formed on the end member to improve the connection strength between the handrail body and the end member, improving the ability to prevent the end member from coming loose from the handrail body and the ability to prevent deformation of the portion of the end member that blocks the lateral end of a specified space. It also prevents the lateral end of the handrail body from significantly deforming toward the wall.

FIG. 10 is a cross-sectional view corresponding to FIG. 8, showing a first modified example of the present invention. FIG. 10 is a cross-sectional view corresponding to FIG. 8, showing a second modified example of the present invention.

As shown in Figure 1, a continuous handrail T according to the present invention is attached to a wall surface H that extends vertically and horizontally. This continuous handrail T comprises a handrail body 10 that extends horizontally, a pair of left and right end members 20 attached to each horizontal end of the handrail body 10, and a cover member 40 (see also Figures 2 and 5).

The handrail body 10 has a uniform cross-sectional shape along its entire horizontal length. The cover member 40 has a uniform cross-sectional shape along its entire horizontal length and is the same length as the handrail body 10. The handrail body 10 and cover member 40 are each integrally formed from synthetic resin.

Next, the handrail main body 10 will be described with reference to Figures 1 to 5. First, the handrail main body 10 is broadly divided into a base portion 11, a grip portion 12, and an overhang portion 13.

The base portion 11 serves as the attachment portion to the wall surface H, and has a flat attachment surface 11a that abuts against the wall surface H. The base portion 11 is fixed to the wall surface H with fixing screws 51, with the attachment surface 11a abutting against the wall surface H (see Figures 3 and 4).

The gripping portion 12 is set at a position spaced apart from the wall surface H and higher than the base portion 11. The overhanging portion 13 connects the base portion 11 to the lower end of the gripping portion 12. In this embodiment, the overhanging portion 13 extends from the base portion 11 in a direction away from the wall surface H, and then extends upward to connect to the lower end of the gripping portion 12. The shape (cross-sectional shape) of the overhanging portion 13 is not limited to that shown in this embodiment, and can be any suitable shape, such as extending in a substantially straight line from the base portion 11 toward the underside of the gripping portion 12.

The grip portion 12 has a cross-sectional shape with a rounded convex shape that protrudes upward, making it easy to grip with the fingers. The surface of the grip portion 12 facing the wall surface H is a bulge portion 12a that bulges out relative to the protruding portion 13. In other words, a space is formed below the bulge portion 12a. A user holding the grip portion 12 can also grasp the underside of the bulge portion 12a with their fingertips, making the shape of the grip portion 12 preferable for a firm grip. The distance between the grip portion 12 and the wall surface H can be any appropriate size, as long as the user's fingers can be inserted comfortably.

The handrail body 10 has a hollow rib structure with multiple cavities formed inside by rib sections 14 extending vertically and horizontally (see Figures 2 and 5). Of these cavities, the cavities formed within the grip section 12 are indicated by the reference numeral 15, and the predetermined cavities formed in the base section 11 are indicated by the reference numeral 16.

The handrail body 10 has a mounting recess 17 that opens downward and forward at the boundary between the base portion 11 and the overhang portion 13. The fixing screw 51 penetrates the base portion 11 from the front side of the mounting recess 17 toward the wall surface H, securing the base portion 11 to the wall surface H. The mounting recess 17 is covered with a cover member 40. Note that the cover member 40 is used to cover the mounting recess 17 after the fixing work with the fixing screw 51 has been completed, and after the work of fixing the end member 20 to the wall surface H with the fixing screw 52 (see Figures 3 and 4) has been completed, as described below (the fixing screws 51 and 52 are hidden by the cover member 40).

When the handrail body 10 is attached to a wall H, a predetermined space K is formed on the rear (back) side of the handrail body 10, extending laterally along the handrail body 10. Specifically, the space K is partitioned by the wall H, the base 11, the overhang 13, and the grip 12, and is open upward. Furthermore, when the end members 20 are not attached to the handrail body 10, the space K is also open at each lateral end of the handrail body 10. Here, the cross-sectional shape of the space K is shown as the area hatched with imaginary lines in Figure 5, assuming that the height position of the upper end of the grip 12 is the maximum height position. More specifically, the cross-sectional shape of the space K corresponds to the shape bounded by an imaginary horizontal line α extending from the upper end of the grip 12 toward the wall H, an imaginary vertical line β corresponding to the wall H, and the back surface of the handrail body 10, and exists throughout the entire length of the handrail body 10.

Next, the end member 20 will be described in detail with reference to Figures 6 to 10. Because the left and right end members 20 are substantially symmetrical, the following description will focus on the right end member 20. Furthermore, in the following description, with regard to the directionality of the handrail main body 10 and end member 20, the side farther from the wall surface H will be referred to as the front or front side, and the side closer to the wall surface H will be referred to as the rear or back side.

First, the end member 20 is integrally formed from synthetic resin and is shaped to completely cover the handrail main body 10 and the space K from the sides. Therefore, the end member 20 has a main body wall portion 21 that completely covers the handrail main body 10 and the space K. In this embodiment, the main body wall portion 21 is plate-shaped and extends perpendicular to the wall surface H.

A mating protrusion 22 is formed on the inner surface of the main body wall 21 (the surface that is attached to the handrail main body 10). The cross-sectional shape of the mating protrusion 22 is substantially the same as the cross-sectional shape of the space K. This mating protrusion 22 protrudes into the space K and closes the lateral end of the space K.

The fitting protrusion 22 has a hollow structure. Specifically, the fitting protrusion 22 has an upper flange 23 that extends from near the upper end of the gripping portion 12 toward the wall surface H and inward (toward the space K) from the upper edge of the main body wall 21, a vertical surface 24 that extends downward from the inner edge of the upper flange 23, and a connecting surface 25 that connects the edge of the vertical surface 24 to the main body wall 21. This connecting surface 25 is shaped to fit along the back surfaces of the base portion 11, the overhang 13, and the gripping portion 12.

As described above, the fitting protrusion 22 has a hollow structure (box structure) surrounded by the main body wall 21, upper flange 23, vertical surface 24, and connecting surface 25, providing high rigidity while also reducing weight. The surface of the fitting protrusion 22 facing the wall H (back surface) may be either a closed structure or an open structure.

As shown in Figure 8, the distance t between the end member 20 (main body wall portion 21 and fitting protrusion 22) and the wall surface H is set to be as small as possible. In this embodiment, the distance t is set to 2 mm or less. Of course, the distance t may also be set to 0 (so that the wall surface H and the end member 20 come into contact).

The end member 20 is attached to the handrail body 10 by fitting it onto the outer periphery of the lateral end of the handrail body 10. To fit this onto the handrail body 10, the body wall 21 is formed with a lower flange 26A and a connecting flange 26B in addition to the fitting protrusion 22 (see Figures 6 and 8). The lower flange 26A extends along the underside of the base 11 and the overhang 13. The connecting flange 26B smoothly connects the upper flange 23 and the lower flange 26A. That is, the connecting flange 26B extends from the lower flange 26A along the front surface of the gripping portion 12, reaching the upper end of the gripping portion 12. The lower flange 26A and connecting flange 26B together form the surface-side flange 26, which is located on the surface side of the end member 20 from the upper end of the gripping portion 12.

The protruding height of the connecting surface portion 25 from the main body wall portion 21 is the same as the protruding length of the lower flange portion 26A and the connecting flange portion 26B from the main body wall portion 21. The inner area surrounded by the connecting surface portion 25, the lower flange portion 26A, and the connecting flange portion 26B forms the fitting recess 27 into which the outer periphery of the lateral end of the handrail main body 10 fits.

A first connecting protrusion 28 and a second connecting protrusion 29 are formed protruding from the main body wall 21 of the end member 20 in the protruding direction of the fitting protrusion 22. The protruding height of each connecting protrusion 28, 29 is made sufficiently greater than the protruding height of the fitting protrusion 22.

The first connecting protrusion 28 is fitted into the hollow portion 15 formed in the grip portion 12 (see Figure 8). The cross-sectional shape of the first connecting protrusion 28 from the top to the front and rear surfaces corresponds to the cross-sectional shape of the inner surface of the grip portion 12. When the first connecting protrusion 28 is fitted into the hollow portion 15 within the grip portion 12, the inner surface of the grip portion 12 is fitted without rattle into the first connecting protrusion 28, and the outer surface of the grip portion 12 is fitted without rattle into the inner surface of the connecting surface portion 25 of the end member 20 and the inner surface of the connecting flange portion 26B.

To ensure a smooth and rattle-free fit between the first connecting protrusion 28 and the gripping portion 12, the outer peripheral surface of the first connecting protrusion 28 is formed with multiple guide ribs 30 spaced apart in the circumferential direction and extending in the mating direction, and guide ribs 31 are formed on the inner surface of the connecting surface portion 25 and the inner surface of the flange portion 26 at positions opposite the guide ribs 30 and extending in the mating direction (see Figure 8). The protruding height of each guide rib 30, 31 gradually decreases toward the tip end in the mating direction (see Figure 7, ensuring a smooth fit).

The second connecting protrusion 29 is fitted into the hollow portion 16 formed in the base portion 11 of the handrail main body 10. Then, while the second connecting protrusion 29 is fitted into the hollow portion 16, it is fixed to the wall surface H with a fixing screw 52 (fastened together with the base portion 11). The hollow portion 16, i.e., the second connecting protrusion 29, is positioned so that it overlaps the mounting recess 17 horizontally. Then, the fixing screw 52 is inserted through the mounting recess 17 for fastening.

A positioning rib 32 protrudes from the main body wall 21 and extends in the same direction as the fitting protrusion 22. When the end member 20 is fitted to the outer periphery of the lateral end of the handrail main body 10, the lateral end face of the handrail main body 10 abuts against the positioning rib 32, preventing it from fitting any deeper.

When the lateral end face of the handrail body 10 abuts against the positioning rib 32, the engagement depth of the engagement protrusion 22 and flange portion 26 relative to the handrail body 10 is indicated by the symbol F in Figure 9. The greater this engagement depth F, the more preferable it is for increasing the bond strength (connection strength) between the handrail body 10 and the end member 20. From the perspective of ensuring sufficient bond strength and preventing the end member 20 from becoming too large, it is preferable to set the engagement depth F in the range of 5 mm to 30 mm. Note that the engagement depth of the engagement protrusion 22 relative to the handrail body 10 and the engagement depth of the flange portion 26 relative to the handrail body 10 may be different.

The handrail body 10 and end member 20 are also fixed together with an adhesive, and the adhesive application surface γ is shown by the two-dot chain line in Figure 6. As indicated by the application surface γ, the handrail body 10 is bonded to the end member 20 along its entire outer periphery. The inner surface of the grip portion 12 is also bonded to the top surface and front and rear surfaces of the first connecting protrusion 28 of the end member 20.

When the continuous handrail is attached to a wall, the outer surface of the end member 20 is designed to be an entirely smooth surface, with no uneven or stepped areas on which objects can be hung. The outer surface at the connection point between the end member 20 and the handrail main body 10 is also designed to have no uneven or stepped areas on which objects can be hung. In this embodiment, these outer surface shapes are designed so that objects with a width of approximately 2 mm or more cannot be hung on them.

Although the above describes the embodiments, the present invention is not limited to these and can be modified as appropriate within the scope of the claims, including, for example, the aspects described below. For example, the main body wall 21 of the end member 20 does not have to be flat, but can instead be convexly curved and bulge outward in the lateral direction of the handrail main body 10. The cross-sectional shape of the fitting protrusion 22 of the end member 20 has a shape that follows the wall surface H, base portion 11, overhang 13, and grip portion 12, and can be set to any appropriate shape as long as its upper surface height is the same as or higher than the lower end position of the grip portion 12.

Figure 11 shows a first modified example of the present invention; components that are the same as those in the previous embodiment are assigned the same reference numerals and redundant descriptions will be omitted (the same applies to the second modified example shown in Figure 12, described below). In this modified example, the height of the upper flange portion 23 that forms the upper surface of the fitting protrusion 22 is the same as or slightly higher than the lower end of the bulge portion 12a of the gripping portion 12. The upper surface of the upper flange portion 23, in a portion near the upper end of the gripping portion 12, forms an inclined surface 23a that gradually decreases in height from the upper end of the gripping portion 12 toward the wall surface H. Even if an object is hung on the inclined surface 23a, as long as a component of force acting in a direction away from the wall surface H acts on the object, the object will slide down the inclined surface 23a, pass the upper end of the gripping portion 12, and fall toward the surface of the gripping portion 12, making it difficult to maintain the hanging state.

Figure 12 shows a second modified example of the present invention. In this modified example, the handrail body 10 has a divided structure, separated at the boundary between the base portion 11 and the overhang portion 13. In other words, the grip portion 12 and the overhang portion 13 are formed integrally, while the base portion 11 is constructed as a separate body from the grip portion 12 and the overhang portion 13 (an overall two-piece structure).

The base portion 11 and the overhang portion 13 are connected by an engagement relationship described below and secured by a fixing screw 53. The fixing screw 53 penetrates from below through the area where the base portion 11 and the overhang portion 13 overlap in the vertical direction, and is secured to the second connecting protrusion 29 formed on the end member 20 (the base portion 11, the overhang portion 13, and the second connecting protrusion 29 are fastened together).

To achieve this engagement, the base portion 11 is formed with an engagement groove 11b and a locking claw 11c. The overhang portion 13 is formed with an engagement claw 13a and a locking groove 13b. The locking claw 11c of the base portion 11 is engaged with the locking groove 13b of the overhang portion 13, and the locking claw 13a of the overhang portion 13 is engaged with the locking groove 11b of the base portion 11. After these engagements are made, the unit is fixed in place using the fixing screw 53.

The outer surface shape of the upper cross section of the gripping portion 12 is trapezoidal, with a nearly flat upper surface, and does not have a bulge 12a. Furthermore, as shown in Figure 8, the mating protrusion 22 is shaped to completely block the lateral side of the specified space K. This makes it an extremely desirable shape for preventing objects from getting caught on the lateral ends of the handrail body 10.

The first connecting protrusion 28 formed on the end member 20 protrudes and fits into a single large cavity 15B formed inside the gripping portion 12 and the protruding portion 13. This first connecting protrusion 28 has an outer surface shape that corresponds to the inner surface shape of the gripping portion 12 and the protruding portion 13, and has a larger cross-sectional shape than the cases shown in Figures 8 and 11 (ensuring a stronger connection between the handrail main body 10 and the end member 20).

It is also possible to form the base portion 11 and the overhang portion 13 as a single unit, with the grip portion 12 formed separately from the base portion 11 and the overhang portion 13 (two-piece configuration). Alternatively, the base portion 11, the grip portion 12, and the overhang portion 13 may all be formed as separate units (three-piece configuration). Of course, the objectives of the present invention are not limited to those explicitly stated, and implicitly include providing what is substantially preferred or expressed as an advantage.

The present invention is suitable for use as a continuous handrail in buildings such as homes, offices, hospitals, public facilities, and commercial facilities, as well as in structures attached to buildings.
