Description

The present invention relates to a staircase handrail device and a staircase handrail system suitable for use in the fields of nursing care and welfare.

In order to ensure the safety of elderly people and supporters requiring nursing care when walking on their own at home, nursing homes, hospitals, etc., handrails are attached to the walls of corridors and stairs, or in corridors and entrances. Stationary handrail devices and handrail systems are installed.

As a conventional stationary handrail device, for example, a device including a base portion, a strut portion erected on the base portion, and a handrail portion supported by the strut portion is known (for example,). , Patent Documents 1 and 2).

Further, as a conventional handrail system, a system in which a plurality of handrail devices as described above are prepared and a handrail is erected between these handrail devices is known. As an example, the first base plate, the second base plate, the first strut attached to the first base plate, the second strut attached to the second base plate, and the first strut attached to the upper end of the first strut. A hinge, a first handrail mounting portion attached so that the angle can be changed with respect to the first strut via the first strut, a second hinge attached to the upper end portion of the second strut, and a second hinge. A device having a second handrail mounting portion attached so that the angle can be changed with respect to the second strut and a first handrail bridged between the first handrail mounting portion and the second handrail mounting portion is provided. (See, for example, Patent Document 3).

All of the above-mentioned ones disclosed in Patent Documents 1 to 3 are used in places where the installation space is not restricted to the handrail device, such as the floor surface in a room or the porch of the entrance. Here, when it is necessary to install the handrail device in the middle of the stairs, that is, when the handrail device must be installed also in the step of the stairs, the tread surface of the stairs is usually narrower than 300 mm. In the above-mentioned conventional handrail device, the base portion (base plate) is too large to be installed.

Therefore, there is a handrail device in which the width dimension of the base portion is narrower than the tread surface of the stairs so that it can be installed even in the middle of the stairs (see, for example, Patent Document 4 and Non-Patent Document 1).

By the way, the handrail device is required to have stability so as not to fall unexpectedly during use. In response to this, the applicant of the present application has proposed a handrail device in which a weight is provided on the back surface of the base portion (see Patent Documents 5 and 6).

Since the stairs are the place where the elderly and supporters requiring nursing care (hereinafter referred to simply as the elderly) feel the most anxiety and fear, the elderly, etc. should use the handrail device installed on the stairs. Relies more on handrails installed on flat surfaces such as corridors. Therefore, the handrail device installed in the middle of the stairs, that is, on the step, is required to have the same level of stability as the handrail device installed in another place.

Therefore, in order to respond to this, in the handrail device disclosed in Patent Document 4 and Non-Patent Document 1, the length of the base portion is extended as compared with that of the general-purpose handrail device installed in another place. Trying to get stability.

However, if the stairs are wide, the length of the base is not restricted. Therefore, although the conventional handrail device can be installed, if the width of the stairs is narrower than the length of the base, it is natural. However, there is a problem that it cannot be installed.

Therefore, in order to solve this problem, it is considered that stability can be ensured by increasing the thickness of the base portion and increasing the weight of the base portion itself instead of extending the length of the base portion.

However, when trying to give the minimum weight necessary to ensure the stability of the base part, the base part is much smaller than the base part of a general-purpose handrail device, so the thickness of the base part is usually It has to be much thicker than in the case of. In that case, the height level at the time of installation of the base part (height dimension from the tread surface of the stairs to the upper surface of the base part) becomes high, so that elderly people who are not aware of their feet can easily trip over the base part and fall accidents. Etc. will be invited. This impairs the original purpose of the handrail device. Therefore, it is not a good idea to increase the thickness of the base portion to increase the weight of the base portion itself.

In that case, if the weights disclosed in Patent Documents 5 and 6 are adopted, the above-mentioned problems will be solved.

However, when attaching the weight to the base portion whose width dimension is smaller than the base portion of the general-purpose handrail device, it is naturally necessary that the external dimension of the weight is equal to or smaller than the external dimension of the base portion. be. Therefore, a weight having such a size does not reach the required weight, and even if such a weight is attached to the base portion, stability cannot be ensured. In that case, in order to gain enough weight to ensure stability, the thickness of the weight must be increased. However, even in that case, although the height level at the time of installing the base part can be suppressed as compared with the case where the thickness of the base part is increased, it is possible to avoid the height level at which elderly people and the like are likely to stumble. do not have.

The present invention has been made to solve the above problems, and can be installed even on the steps of stairs where the length of the base portion is restricted, has excellent stability, and has the base portion. It is an object of the present invention to provide a handrail device for stairs and a handrail system for stairs in which the height level is suppressed to a level at which elderly people and the like are less likely to stumble.

In order to solve the above problems, the staircase handrail device according to the present invention includes a base portion installed on the floor surface and a handrail portion, and the strut portion erected on the strut mounting portion arranged on the base portion. A staircase handrail device that includes a plate-shaped weight provided on the back surface of the base portion and is installed on a staircase having a tread surface dimension of not exceeding 300 mm. An inclined surface toward the floor surface is provided on the peripheral edge portion, whereby the weight is accommodated in the space formed between the back surface of the base portion and the floor surface, and the base portion and the base portion. The total weight of the weight is at least 13 kg, and the thickness of the base portion and the thickness of the weight are equal to each other.

According to the above invention, the total weight of the base portion and the weight is at least 13 kg, and the thickness of the base portion and the thickness of the weight are equal to each other. Height level (height dimension from the tread of the stairs to the upper surface of the base) can be suppressed.

In the above-mentioned handrail device for stairs, the support column attachment portion may be arranged over a plurality of locations of the base portion, and the attachment position of the support column portion with respect to the base portion may be changed.

In this case, the position of the handrail portion can be easily changed according to the installation environment, for example, near one end of the base portion, near the center of the base portion, near the other end of the base portion, or both ends of the base portion. It becomes.

Further, in the above-mentioned handrail device for stairs, the weight may be provided with a notch at a portion corresponding to the support column mounting portion, and the back surface of the base portion may be exposed at the notch.

In this case, since the strut portion is attached to the base portion, the length of the fixing screw can be suppressed by the thickness of the weight, and the number of types of screws used for the handrail device can be suppressed. As a result, it takes time to select the screws at the time of assembly, and it is possible to prevent an assembly error due to a wrong type of screws.

The handrail system for stairs according to the present invention includes at least one general-purpose handrail device including a base portion installed on a floor surface, a handrail portion, and a strut portion erected on the base portion, and the above. It is characterized in that it is composed of at least one handrail device for stairs, and a connecting handrail that connects the general-purpose handrail device and the handrail device for stairs to each other.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The components common to each of the following embodiments are designated by the same reference numerals.

-Handrail device for stairs-
An embodiment of the handrail device for stairs according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a handrail device for stairs, and FIG. 2 is a partially enlarged cross-sectional view of the handrail device for stairs.

The staircase handrail device 1 includes a base portion 10, a pair of strut portions 11 and 11 erected on the base portion 10, and a plate-shaped weight 30 attached to the back surface of the base portion 10. It is a thing. Hereinafter, these main parts will be described.

-Base part-
The base portion 10 has a function of fixing the handrail device 1 for stairs to the floor surface. An inclined surface 10a toward the floor surface is provided at the peripheral end portion of the base portion 10 of the present embodiment, whereby the central portion of the base portion 10 is lifted from the floor surface, as shown in FIG. A space for attaching the weight 30, the fixing screw 40 to be described later, the support column fixing member such as the back flange 50, and the like to the back surface of the base portion 10 is secured.

The base portion 10 in this manner has a size that can be installed on the step F (see FIG. 6) of the stairs S. Specifically, since the dimension of the tread surface of the stairs S generally does not exceed 300 mm, the width dimension W is slightly smaller than 300 mm, for example, 290 mm so that it can be installed on a staircase having such dimensions. ing. The width dimension W of the base portion 10 may be the same as the dimension of the tread surface of the stairs to be installed, but the above-mentioned As described above, it is preferable to set the size slightly smaller than the dimension of the tread surface. Further, if the width dimension W is extremely smaller than the tread dimension, it is disadvantageous in terms of gaining weight. From this point as well, as described above, it is preferable that the width dimension W is kept to such an extent that it does not easily slide off the step F.

Further, the length L1 of the base portion 10 is set to be the same as the length of the base portion 20 of the general-purpose handrail device 2 (see FIG. 6). As a result, when the handrail system for stairs as shown in FIG. 6 is assembled, it is possible to create an impression that the system as a whole has a cohesive design.

Since the base portion 10 in this manner needs to have a weight in itself, it is formed from a metal plate such as a steel plate. The thickness of the base portion 10 will be described later in the description of the weight 30.

-Strut part-
The base end of the support column 11 is inserted into a metal tubular holder portion 11a erected near one end in the longitudinal direction of the base portion 10, and is fixed by a screw 11b in the middle of the holder portion 11a. ing. A metal mounting base 11c is attached to the lower end of the holder portion 11a by welding, and the holder portion 11a is fixed by being inserted into a screw hole 11d provided in the mounting base 11c from the outside of the weight 30 as shown in FIG. The holder portion 11a is fixed to the base portion 10 by screwing the screw 40. Further, the head portion 40a of the fixing screw 40 is locked to the back flange 50 attached to the weight 30 side. A cross rail 11e is erected between the two strut portions 11 and 11 via an elbow member 11f near the upper end of the strut portion 11 as described above, and a handrail portion 11g is provided at the upper end. In FIG. 2, reference numeral 10c is provided on the entire surface of the metal base portion 10 and the entire surface of the weight 30 on the back surface, and reference numeral 10d is provided on the surface of the urethane coating 10c. Shows the applied decorative coating layer. Further, reference numeral 10e indicates a cushioning material made of, for example, rubber or synthetic resin, which is attached to the peripheral edge portion of the inclined surface 10a, and the cushioning material 10e prevents scratches on the floor surface and adjusts the non-landing surface. And stability is ensured.

-Weight-
The weight 30, together with the base portion 10, is for imparting stability to the handrail device 1 for stairs. The weight 30 is also formed from a metal plate such as a steel plate. Specifically, for example, hot-rolled steel sheets such as SPHC, cold-rolled steel sheets such as SPCC, zinc-plated steel sheets made of hot-rolled steel sheets such as SGHC, and zinc made of cold-rolled steel sheets such as SGCC. Examples thereof include various steel sheets such as plated steel sheets and various stainless steel sheets such as SUS304, SUS430, SUS316 and SUS443J1. Further, the size of the weight 30 is set to be a size that fits in a flat region on the back surface of the base portion 10 except for the inclined surface 10a provided at the peripheral end portion of the base portion 10, and is set on the back surface of the base portion 10, for example. It is fixed by welding. The thickness of the weight 30 in this way is made equal to the thickness of the base portion 10. Specifically, for example, when the width dimension W of the base portion 10 is 290 mm, the length dimension L1 is 800 mm, and the total weight of the base portion 10 and the weight 30 is 13 kg to 15 kg, the thickness of the weight 30 is 4. It is set to 5 mm. The thickness of the base portion 10 is also 4.5 mm, similar to the weight 30.

Here, assuming that the thickness of the base portion 10 is, for example, 3.2 mm as in the base portion of the conventional handrail device, the weight is the same as in the above-described embodiment (total weight of the base portion 10 and the weight 30). ), The thickness of the weight 30 needs to be 6.0 mm or more. Then, the total thickness of the base portion 10 and the weight 30 in this case is 9.2 mm, which is slightly thicker than the thickness of 9.0 mm of the above-described embodiment, and the height of the upper surface of the base portion 10 is high. The level will be higher than that of the embodiment. Then, when the weight 30 is to be further gained weight, the thickness of the weight 30 becomes thicker, so that the slope of the inclined surface 10a of the base portion 10 becomes larger in order to store this on the back surface of the base portion 10. As a result, the height level of the upper surface of the base portion 10 becomes high. Therefore, as described above, by making the thicknesses of the base portion 10 and the weight 30 equal to each other, the weight required for obtaining stability is secured, and the increase in the combined thickness of the base portion 10 is suppressed as much as possible. The height level of the upper surface of the weight can be suppressed.

Here, as shown in FIGS. 3 to 5, the weight 30 is provided with a notch 31 at a position corresponding to the support column mounting portion 10b so that the back surface of the base portion 10 is exposed at the notch 31. May be good. By doing so, the length of the fixing screw 40 for attaching the holder portion 11a of the strut portion 11 to the base portion 10 can be suppressed by the thickness of the weight 30, and the type of screw used for the handrail device 1 for stairs. Can be suppressed from increasing. As a result, it takes time to select the screws at the time of assembly, and it is possible to prevent an assembly error due to a wrong type of screws.

The shape and the number of arrangements of the cutouts 31 are not limited to those shown in the illustrated example. In the illustrated example, the notch 31 has a semicircular shape, but has an arbitrary shape such as a U-shape or a circular shape. Further, the number of arrangements also increases or decreases according to the number of attachment points of the support column 11.

In FIG. 1, reference numeral 60 indicates a decorative cap, and the decorative cap 60 is used to close an insertion hole for a fixing screw 40 in the base portion 10 that is not used (a portion where the support column 11 is not attached). It is composed of, for example, a cap body 60a molded from a synthetic resin and a plurality of locking claws 60b (see FIG. 3) that are fitted into the insertion holes and locked.

-Handrail system for stairs-
Next, an embodiment of the handrail system for stairs according to the present invention will be described with reference to FIG. FIG. 6 is a perspective view showing an embodiment of a handrail system for stairs.

The staircase handrail system 100 is a combination of the staircase handrail device 1, the general-purpose handrail device 2, and the connecting handrail 3. This figure shows an example in which the staircase handrail system 100 is installed on the stairs S of the entrance porch P. The general-purpose handrail device 2 is installed on the entrance porch P, and the staircase handrail device 1 is installed on the step F of the stairs S. is set up. In both the general-purpose handrail device 2 and the staircase handrail device 1, the support columns 11 and 21 are attached to one ends of the respective bases 10 and 20, and the bases 10 and 20 of both 1 and 2 are the stairs S. It is a passage. Then, a connecting handrail 3 is erected between the support columns 11 and 21 of both 1 and 2.

Here, since the general-purpose handrail device 2 is installed on the entrance porch P having a large area, the size of the base portion 20 thereof is not particularly limited as in the conventional handrail device. On the other hand, in the example of this figure, the handrail device 1 for stairs is installed on the stairs S in which the dimension of the tread surface of the step F is 300 mm, so that the width dimension of the base portion 10 is 290 mm. Further, since the length dimension L1 of the base portion 10 of the staircase handrail device 1 is set to be the same as the length dimension L2 of the base portion 20 of the general-purpose handrail device 2, the system as a whole gives an impression of being cohesive in design. I can create it.

The connecting handrail 3 includes a handrail main body 3a, connecting members 3b attached to both ends of the handrail main body 3a, and a strut gripping portion 3c connected to the connecting member 3b. Then, in the connecting handrail 3 as described above, the strut gripping portion 3c is provided between the handrail portions 11g and 21g of the strut portions 11 and 21 of the general-purpose handrail device 2 and the staircase handrail device 1 and the cross rails 11e and 21e. By grasping, it is erected between the support columns 11 and 21. Further, since the connecting members 3b at both ends of the handrail main body 3a and the upper end portions of the support column gripping portions 3c are pivotally attached, it is possible to cope with the height difference in the stairs S. As the configuration of the connecting member 3b and the strut gripping portion 3c, for example, the configuration disclosed in Japanese Patent Application Laid-Open No. 2013-92034 according to the application of the applicant of the present application can be adopted.

Next, FIG. 7 is a perspective view showing a modified example of the handrail system for stairs. In the handrail system 101 for stairs shown in this figure, the positions of the support columns 11 and 21 are different from those shown in FIG. That is, in this example, the support columns 11 and 21 of the general-purpose handrail device 2 and the staircase handrail device 1 are attached to the center of the base portions 10 and 20 in the longitudinal direction. As a result, both sides of these support columns 11 and 21 are used as passages for the stairs S. Since the remaining configuration is the same as that shown in FIG. 6, the description thereof will be omitted.

FIG. 8 is a perspective view showing another modification of the handrail system for stairs. The staircase handrail system 102 shown in this figure is different from the one shown in FIGS. 6 and 7 in the number and position of the support columns 11 and 21. That is, in this example, the support columns 11 and 21 of the general-purpose handrail device 2 and the staircase handrail device 1 are attached to both ends of the base portions 10 and 20 so as to face each other. As a result, as in the example shown in FIG. 6, these base portions 10 and 20 are used as passages for the stairs S, and connecting handrails 3 and 3 are arranged on both sides of the passages. In the case of such a form, since the handrail portions 11g, 21g, 3 exist on both sides of the passage of the stairs S, it is possible to give a greater sense of security to the elderly and the like.

In the examples shown in FIGS. 6 to 8, one staircase handrail device 1 and one general-purpose handrail device 2 are used. For example, another general-purpose handrail device 2 is used as a staircase. It may be installed on the road surface below the handrail device 1, or when the stairs S are long (many steps F), a plurality of stair handrail devices 1 may be installed.

It should be noted that the present invention can be practiced in various other forms without departing from its spirit or major features. Therefore, the above embodiments are merely exemplary in all respects and should not be construed in a limited way.
