Description

  The present invention relates to a horizontal step eliminating member for a stair tread board step nose and a squeeze plate, which is mounted to prevent rolling to a horizontal step between a tread plate nose and a squeeze plate when climbing a wooden box-shaped staircase in a house.

  In a wooden box shape staircase in a house, the tread board nose part usually protrudes more than the squeeze board, and when climbing the stairs, the toe gets caught in the projecting part of the nose part of the staircase and injuries, falls, falls, etc. From the stairs accident was a big problem. In order to cope with these problems, it has been conventionally known that a member is attached to the lower surface of the nose of the tread board in order to prevent whirling when the stairs are raised and lowered. Reference numeral 10 in FIG. 3 shows an example of a nose member attached to a conventional stair tread.

However, many of the reference numerals 10 in FIG. 3 are manufactured and attached at any time upon request, and most of them are made of wood. Therefore, when considering commercialization to meet the demand for installation in wooden box-shaped staircases of various houses, it is difficult to obtain uniform and stable product performance and the production cost is expected to be high. For this reason, the actual product has not been commercialized.

In addition, for prevention of whirling when moving up and down the stairs, for example, Japanese Patent Application Laid-Open No. 10-219952 discloses a stairs slip stopper and a bruise cushioning material having a whirling prevention function provided on the lower surface of the tread of the stairs. Japanese Laid-Open Patent Publication No. 11-62152 discloses a protection member for a tread of a staircase that also serves as a slip stopper. Japanese Patent Application Laid-Open No. 11-172875 discloses a staircase in which a soft auxiliary member is attached to the lower surface of a step nose portion of a footboard. Further, in Japanese Patent Application Laid-Open No. 2003-262024, a vertical portion and an inclined portion made of a flexible material coupled to a lower end of the vertical portion are attached to the lower surface of the nose portion of the stair tread plate and the rake plate. A stair nosing adjusting member having a horizontal portion at the upper end and lower end of the portion is disclosed.

  However, the dimensions of the stairs in the house are very different, and the actual situation is that the stairs are constructed with various dimensions such as the horizontal distance between the tip of the step nose of the tread board and the rake board, the thickness of the tread board, etc. It is extremely difficult to install and install a snoring prevention member that fits perfectly.

In addition, due to the enactment of the Long-term Care Insurance Law and social background, the ratio of staying at home for elderly and physically disabled people and the rate of living with healthy families are both high, increasing the need for housing renovation work, In order to prevent falling and falling accidents, products with anti-slip measures on the top surface of the nose at the tip of the tread plate and auxiliary members with such functions have been developed, but most of them are aimed at preventing falling when falling up and down the stairs As a countermeasure to prevent slipping to the top of the nose top of the tread board, many of the back ones often have a new step after installation, and depending on the body part that the elderly and disabled people are inconvenient It may cause a fall or fall. In addition, by specifying the target of these measures for the elderly and the disabled, it may not be suitable for families with healthy people, so consider not to interfere with general stair climbing movements. There is a need to.

In the stair member disclosed in Japanese Patent Laid-Open No. 10-219952, the stiffening prevention portion that covers the space formed by the bottom surface of the tread plate and the rake plate is made of a flexible material, and its performance is determined by sliding when the stairs are raised and lowered. It is a coupled member made of the same material that has the functions of stopping, preventing injuries at the front and corners of the nose, and preventing rolling when climbing the stairs, and only a part having one of these functions Mounting with is impossible. For example, it is impossible in terms of the member structure to cut and use an inclined member that covers the space from the lower end of the step nose of the stair tread plate to the rake plate to prevent whirling when climbing the stairs.

Further, in the above-mentioned Japanese Patent Application Laid-Open No. 11-62152, a synthetic resin-molded coupling member having the same performance as that of Japanese Patent Application Laid-Open No. 10-219952 is used, and a single member having only one of the functions is also used. Mounting with is impossible. Furthermore, compared with Japanese Patent Laid-Open No. 10-2199552, the range of the tread board thickness and the horizontal dimension between the bottom surface of the nose part of the tread board and the indenting board are small. For example, it is necessary to prepare a spacer according to the size of the work. In addition, due to the nature of the raw materials, a thickness is required to form the variable part of each part, so that the size of the vertical part of the front surface of the tread board nose after installation becomes large, which causes a new whisper.

Further, in Japanese Patent Laid-Open No. 11-172875, the main purpose thereof is for a stair auxiliary member formed from a soft material that is intended to prevent the toes when climbing the stairs, in particular the toes, from being caught on the tread plate nose. When climbing up the stairs, when the toes hit, there is a risk that the shock will be absorbed by the underside of the nose in order to absorb the impact sufficiently. I can't say.

Further, Japanese Patent Application Laid-Open No. 2003-262024 is a stair nosing adjustment member for preventing stair nosing that is attached to a corner formed by a lower surface of a stair tread board and a scooping plate. It is limited to. However, as a method of attaching the nose adjustment member, a ridge that protrudes in a substantially vertical direction at the tip of the upper horizontal portion of the stair nose adjustment member and a ridge that protrudes in a substantially horizontal direction at the tip of the lower end horizontal portion are formed. When mounting on the staircase, it is said that a recess can be provided on the lower surface of the nose portion and the rake plate, and the protrusion can be fitted into the recess, so that the mounting can be performed very easily. However, due to the structure of this nose adjustment member, in order to cover all staircase widths, it is necessary to provide all the staircase widths with recesses on the bottom surface of the nose part and the rake plate. It is difficult to provide a concave line having a uniform depth on the lower surface of the nose portion by using this, and it takes time and labor for the pre-attachment preparation stage, which is not practical. Furthermore, when providing such a concave streak in the existing staircase board, it means dividing the board. In order to cope with this, since it is necessary to take some measures from the back of the stairs, an easy retrofit to the existing stairs is virtually impossible. In order to install this stair nosing adjusting member, it is considered that pre-cutting or the like by pre-cutting or the like is required at the manufacturing stage of the stair tread board and the squeeze board. Therefore, it is not considered to be widely pervasive.

Means to solve the problem

  In order to solve the above-mentioned problem, the step difference member in the horizontal direction of the stair tread board nose and the squeeze board according to the present invention according to claim 1 can be used for lifting the stairs attached to the bottom part of the stair tread board nose and the squeeze board. Prevents the horizontal step difference between the stair tread plate step nose and the squeeze plate, and is a single forming material with a 45 degree slope from the bottom end of the stairs tread plate nose to the squeeze plate. It is characterized in that it does not cause a deformation to an existing product accompanying the above.

According to a second aspect of the present invention, there is provided a horizontal step eliminating member between the stair tread plate step nose and the squeezing plate according to the present invention. It consists of a single, slightly flexible material such as expanded polystyrene with an equilateral triangular shape and smooth finish on each side. It is possible to correspond to a box-shaped staircase.

Further, the horizontal step elimination member between the stair tread plate nose and the escape plate according to the present invention described in claim 3 is the horizontal step elimination member between the stair tread plate nose and the escape plate according to claim 1 or 2. Attaching double-sided tape to the horizontal and vertical surfaces of the member, 2.5mm pilot hole processing for fixing screws to the horizontal and vertical surfaces from the inclined surface, and 2mm x 19mm wood screws to the screw fixing holes It is screwed and fixed with a Phillips screwdriver, and is easy to be retrofitted and can be installed without the need for special tools or techniques.

Effect of device

  According to the present invention as set forth in claim 1, the cross-section of the member at the corner formed by the lower surface of the step board nose portion and the scooping plate is a right-angled isosceles triangle and each surface has a smooth finish. It is possible to effectively prevent the toes from being caught on the lower surface of the step nose when climbing the stairs by covering with a single formation having a slightly rigid flexibility.

In addition, due to the enactment of the Long-term Care Insurance Law and social background, the ratio of elderly people and persons with disabilities living at home and those living with healthy families are both high. It is possible to effectively prevent the tip of the toe or brace from getting caught on the lower surface of the nose when climbing the stairs when using a brace that is fixed to the ankle, etc. In the subsequent state, each operation of the general stair climbing motion is not hindered, and thus the state before the mounting is not affected.

Further, according to the inventions of claim 2 and claim 3, the material is made of a single forming material having a slightly hard flexibility such as expanded polystyrene, and the raw material is excellent in processing performance. Since cutting and processing can be performed according to the cross-sectional dimensions, it can be used for various wooden box-shaped steps, and no special processing is required for existing products, so no special tools or techniques are required. Since it can be attached, it can be expected to be widely available to the general public.

In addition, since the technology for processing and forming the original step of the step difference plate in the horizontal direction of the stair tread plate and nose plate of the present invention from raw materials has already been established, it corresponds to the dimensions of various wooden box-shaped staircases. In addition, it can be manufactured at low cost because it does not require the time and cost required for research for development of production technology. From this, without giving a big burden to severely disabled people (children) daily life equipment benefits, subsidy for remodeling housing for the elderly by each prefecture, and the rehabilitation limit for housing renovation costs stipulated in the Long-term Care Insurance Act Therefore, it can be expected that the effective performance of the stepping plate stair nosing and the squeezing plate of the present invention can be provided widely and generally by the step difference eliminating member in the horizontal direction.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of an embodiment in which a horizontal step eliminating member of a stair tread board nose and a squeeze board according to the present invention is attached to a lower surface of a nose. FIG. 2 is a cross-sectional view of a single step eliminating member in the horizontal direction of the stair tread plate nose and squeeze plate according to the present invention.

In FIG. 1, reference numeral 1 is an example of a horizontal step eliminating member of a stair tread board step nose and a squeeze plate according to the present invention attached to a lower surface of a step nose part of a wooden box-shaped staircase of a house and a corner part formed by a squeeze plate. Show. As shown in FIG. 2, the step eliminating member 1 has a slightly rigid flexibility and has an integrally formed isosceles triangular cross-sectional shape, and serves as an auxiliary function when attached to 4a and 4b. Apply double-sided tape. Further, 2.5 mm drill holes for fixing screws are provided at a pitch of 300 mm so as to be perpendicular or horizontal from the inclined surface to each of the 4a surface and 4b surface. In the case of cutting to the length to be installed, perforations are similarly made at positions of 100 mm from both ends.

As shown in FIG. 1, since the upper and lower ends of the nose of the stair tread plate are chamfered, it is desirable to start the inclined surface from the surface finish of the lower surface of the nose, so it is calculated from the dimension a and the face finish dimension. Select a material that approximates the c dimension.

As shown in FIG. 4, for example, the dimension b, c Both dimensions are based on three types of cross-sectional dimensions.

As shown in FIG. 1, the step eliminating member 1 is bonded to the nose lower surface 8 with 4a and the bump plate surface 9 with 4b using existing double-sided tape. Screw into the 5 mm hole 5 with a Phillips screwdriver using a 20 mm × 19 mm wood screw 6 and fix. In this case, as shown in FIG. 1, when the step eliminating member 1 protrudes from the step plate nose tip vertical portion 7, it can be cut off after installation using a simple tool such as a cutter.

Although the level difference eliminating member 1 is slightly hard, it has flexibility, so that it can be fixed by the mounting method even when the stair tread plate 2 is deformed due to aging.

As described above, according to the step difference member in the horizontal direction of the stair tread plate step nose and the squeeze plate according to the present invention, the cross section of the step is formed by a right-angled isosceles triangle. It is effectively prevented from catching on the lower surface of the nose when climbing up the stairs by plugging it with a single formation with a slightly stiffer flexibility such as expanded polystyrene with a smooth finish on each side. I can do it.

In addition, according to the step difference member in the horizontal direction of the stair tread plate nose and the rake plate of the present invention, it consists of a single forming material having a slightly harder flexibility such as expanded polystyrene, and the raw material has excellent processing performance, Furthermore, since three types of cross-sectional dimensions are configured, the length and each cross-sectional dimension can correspond to various wooden box-shaped steps.

In addition, it can be mounted regardless of the thickness of the tread board, and due to the enactment of the Long-term Care Insurance Law and social background, the ratio of staying at home for elderly and physically disabled people and the rate of living with healthy families are both high. Among adult diseases, hemiplegia is caused by sequelae due to cerebrovascular disorder, etc., and the tip of the toe or orthosis is caught on the lower surface of the nose when climbing the stairs when using an ankle-fixing orthosis Can be effectively prevented, and in the state after the mounting, since it does not hinder each operation of the general stair climbing motion, the state before the mounting is not affected.

Further, according to the step difference member in the horizontal direction of the stair tread plate nose and the rake plate of the present invention, the material is made of a single forming material having a slightly hard flexibility such as foamed polystyrene, and the raw material has excellent processing performance. Since it can be cut and processed according to the length and cross-sectional dimensions, it can be used for various wooden box-shaped stairs and special processing is not required for existing products. Since it can be installed without the need for tools or technology, it can be expected to be widely available.
