Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handrail booklet that is mounted horizontally or at a constant slope from the beginning to the end.

There are many types of handrails, such as rooftop handrails that are installed on rooftops, balcony handrails that are installed on balconies, stair handrails that are installed on stairs, window handrails that are installed on windows, and wall handrails that are installed on the walls of corridors in hospitals, etc. The length and curved shape of the handrails used for such handrails are
They are determined by the length and curved shape of the handrail mounting base on rooftops, balconies, stairs, windows, walls of hallways in hospitals, etc., and there is an extremely wide variety of handrails.

For this reason, it is extremely difficult to standardize and mass-produce handrails that can be applied to all types of handrails, and to manufacture them at low cost. Only the ones used are standardized and mass-produced; for other handrail miniature books, methods such as manufacturing by special order according to the various conditions of the handrail installation location are adopted, and the manufacturing process is limited. The cost was becoming extremely high. However, when we examine in detail the shape of the handrail cap, especially its curved shape, we find that although the angle of bending varies greatly depending on the base of each handrail, rooftop handrails,
Handrail cap wood Z. used for balcony handrails, window handrails, and wall handrails attached to the walls of corridors in hospitals, etc. Yotondo is installed horizontally and the direction of bending is limited to the horizontal direction (lateral direction), and in the case of stair handrails, even if there is a bend in the middle of the stairs, it is mostly limited to diagonal horizontal directions. Or, like a spiral staircase, it has a curved shape with the same slope from the beginning to the end, and the strength and rigidity required for such handrails is not in the horizontal direction but in the vertical direction (vertical direction). direction).

In view of this point of view, the present invention includes a cap body made of a bendable elastic material, and a core material provided inside the cap body along its longitudinal direction made of a metal plate material that is bendable in the thickness direction.

The present invention will be explained in more detail based on embodiments shown in the accompanying drawings.

In FIG. 1, a handrail cap H according to a first embodiment of the present invention is shown.

This handrail cap H is made of elastic and bendable soft synthetic resin such as soft vinyl chloride resin and has a vertical dimension of 40 r.
A Kasagi main body 1 formed in an oval cross-sectional shape with frI1 and a horizontal dimension of 2'', and a bendable Kasagi main body 1 that is provided inside the Kasagi main body 1 along its longitudinal direction and is bendable in the thickness direction. After being bent, the board width is 22m and the board thickness is 3wn as a core material that maintains the bent state against the elasticity of the Kasagi main body.
It is composed of a metal plate material 2 which is an aluminum plate, and is manufactured into a long length by extrusion molding. In this first embodiment, the cap body 1 is made of a relatively soft soft synthetic resin, such as a soft vinyl chloride resin containing a plasticity (a) part, and the metal plate material 2 used as the core material is also made of a soft synthetic resin. The handrail cap H is made of a relatively soft aluminum plate, and as shown in FIG. Bending in the thickness direction (horizontal bending shown by the broken line in Fig. 1) and folding the metal plate 2 in the thickness direction about the Y-Y line that intersects at an angle α with respect to the center line 0. Bending (diagonal horizontal bending) can be easily done by hand bending, and it can also be wound to an appropriate diameter with a winder within the elastic deformation range of the metal plate material or within the plastic deformation range. I can do it. Therefore, according to the handrail cap H of this first embodiment, the handrail mounting base 4, which is the wall surface of a hallway 3a of a hospital, etc., as shown in FIG. When installing the handrail mounting base 4, which is the wall surface of the curved staircase 3b that rises at a slope, first cut the handrail mounting base 4 to match the length, and then bend the handrail cap H at the bending point B. , bend the metal plate 2 in the thickness direction by hand according to the curved shape of the handrail mounting base 4,
The handrail cap H can be attached to the handrail mounting base 4 using the bracket 5.

In this case, the bending of the handrail cap H in FIG.
The bending is in the horizontal direction centered on the line X-X in the figure, and the bending of the handrail cap H in FIG. It is bent diagonally horizontally with the line as the axis. The mounting structure of the handrail cap H using the bracket 5 shown in FIG. 3 is as shown in FIG. Drive the tapping screw 9 into the Kasagi main body 1 of the handrail Kasagi H from the back side through the Kasagi fixing part 7 of the handrail Kasagi H (this is done after forming a small hole with a drill or the like if necessary), and then insert the tip of the tapping screw 9 into the Kasagi body 1 of the handrail Kasagi H. It has a structure in which the part is screwed onto the metal plate material 2, so that the metal plate material 2 used as the core material of the handrail capboard H can be easily bent in the direction of its thickness. Regardless, after being attached to the handrail mounting base 4 using the brackets 5 arranged at predetermined intervals, the handrail cap H exhibited high rigidity also in the width direction. Moreover, FIGS. 6 to 15 show the metal plate material 2 which is the core material of the handrail cap H in the first embodiment.
As shown in FIGS. 6 to 8, bulging ribs 10 are formed along the longitudinal direction at the upper edge, center, or both upper and lower edges of the metal plate 2. The ribs 10 may improve the rigidity and strength of the metal plate 2 in the thickness direction, and may be bent using a simple tool such as a vise or a machine such as a roll bender, as shown in FIG. As shown in FIG. 13, the surface of the metal plate 2 is roughened, the metal plate 2 is provided with through holes 11, the metal plate 2 is provided with cutouts 12 on both upper and lower edges, Furthermore, the metal plate 2 can be shaped by winding a wire 13 or the like around the metal plate 2 or by forming the metal plate 2 with a corrugated plate that waves in the longitudinal direction to make the surface uneven. Board material 2
In addition, as shown in FIGS. 14 and 15, it is possible to improve the bonding strength between the metal plate 2 and the cap body 1 made of an elastic material such as a soft synthetic resin. The metal plate 2 may be formed of a corrugated plate with corrugations, or the metal plate 2 may be formed of a closed cross-section plate having a hollow portion 14 in the longitudinal direction, so that it cannot be folded in the thickness direction without mechanical means such as a roll bender. It is also possible to use a handrail hat H that has a rigidity that cannot be bent.

For example, as shown in FIG. 8, the handrail cap H which has ribs 10 on both upper and lower edges of the metal plate material 2 and exhibits sufficient strength and rigidity against bending in the thickness direction,
As shown in the figure and FIG. 17, the balcony handrail is attached to the handrail mounting base 4 of the balcony 3c via a large number of handrails 15, and exhibits sufficient strength and rigidity not only in the vertical direction but also in the horizontal direction. In addition to being able to be installed as a
As shown in the figure, a handrail cap H in which the metal plate material 2 is formed of a corrugated plate that waves in the width direction and can only be bent diagonally horizontally is shown in FIGS. 18 and 19. As shown, this handrail cap H can be formed into a curved shape that is curved according to a spiral shape of a predetermined pitch, and can be attached to the handrail attachment base 4 of the spiral staircase 3d via the handrail 15.

In addition, the handrail cap H having an oval cross section shown in the first embodiment and its modifications can be installed not only with its longitudinal width perpendicular as described above, but also as shown in FIG. 20, for example. Alternatively, the top handrail mounting base 4 of the stair partition wall 3e may be bent in the horizontal direction and the support 17 may be used to make the vertical width horizontal. In this first embodiment, when driving the tapping screw 9 into the handrail cap H through the cap fixing part 7 of the bracket 5, a small hole is formed using a drill or the like if necessary. Board material 2
Small holes or slits may be provided in advance, and the tip of the tapping screw 9 may be screwed into these small holes or slits.

Furthermore, in the handrail cap H of the second embodiment shown in FIGS. 21 and 22, the cross-sectional shape of the cap body 1 is oval as in the case of the first embodiment, but the metal plate material 2 is It is composed of two plate members 2a and 2b that are divided into two in the width direction and arranged in parallel with each other while maintaining a small gap d. Plate members 2a, 2
A striped pattern 18 is formed in alignment with the small gap d formed by b.

Therefore, according to the handrail kasagi H of the second embodiment, when the handrail kasagi H is fixed to the kasagi fixing part 7 of the bracket 5 by the tapping screw 9, as shown in FIG. It can be screwed into the small gap d formed by the plate members 2a and 2b, and when screwing in the tapping screw 9, it is necessary to form a small hole in the metal plate material 2 of the handrail capboard H using a drill or the like in advance. It disappears. Next, FIGS. 23 to 25 show the handrail cap H of the third embodiment and the roof 3f using this handrail cap H. This figure shows a rooftop handrail installed via a support 17 to the upper end of a post 16 erected on a handrail mounting base 4. Unlike the above embodiments, the cross-sectional shape of the Kasagi main body 1 is a perfect circle. In addition, two striped patterns 18 are formed along the longitudinal direction at the upper and lower ends of the Kasagi main body 1, indicating the width direction of the metal board 2. A receiving portion having an arcuate cross section is formed at the upper end.

Furthermore, FIGS. 26 to 28 show modified examples of the Kasagi main body 2. In FIG. 26, the cross-sectional shape of the Kasagi main body 2 is approximately bulb-shaped, and the handrail is thin. The lower part of the Kasagi H can be fitted into a U-shaped side Kasagi fixing part 7 provided on the bracket 5 and fixed with a tapping screw 9. In addition, in FIG. A through hole is drilled approximately in the center of the thin handrail cap H, which has a cross-sectional shape of approximately a gourd shape, and can be fixed to the bracket 5 with a bolt 19 passing through this through hole. Further, in FIG. 28, the cap body 1 is composed of two cap board members 1a and 1b fixed along the longitudinal direction of the upper and lower edges of a metal plate 2, respectively. , these Kasagi members 1a
, 1b, the metal plate 2 is fixed to the bracket 5 with a bolt 19 using a substantially central portion thereof.

The handrail caps H according to these modified examples utilize the thin portions of the cap body 1 to screw the tapping screws 9 or bolts 19.
can be connected to the bracket 5, and the handrail cap H can be firmly fixed to the bracket 5, and the installation work of the handrail cap H can be made extremely easy. As mentioned above, the handrail cap of the present invention has an extremely soft feel when touched because the cap body is made of a bendable elastic material such as soft synthetic resin, semi-hard synthetic resin, or synthetic rubber. In addition to increasing the degree of freedom in coloring and shaping the handrail kasagi itself, it can be used in a variety of colors to match the surrounding environment, such as rooftops, balconies, stairs, windows, walls in hallways of hospitals, etc. You can color it or consider the cross-sectional shape of the Kasagi body.

In addition, the core material provided inside the Kasagi body along its longitudinal direction is a metal plate that can be bent in the thickness direction and can maintain its bent state against the elasticity of the Kasagi body after being bent. Since the handrail cap is made into a long length during manufacturing, it is cut to match the length of the handrail mounting base during installation, and the handrail cap is bent or deformed to fit the curved shape of the handrail mounting base. It can be applied to an extremely large number of handrails, and can be standardized, mass-produced, and manufactured at low cost. Furthermore, since the handrail cap of the present invention allows a single handrail to be passed from the beginning to the end of the handrail mounting base, there is no need for troublesome installation work such as butting and connecting the ends of the handrail cap along the way. What's more, by using a metal plate as the core material, it can be fixed to the kasagi mounting means such as brackets, balustrades, pillars, etc. using fixing means such as tapping screws and bolts, making the installation work of the balustrade extremely easy. In addition to being easy to use, sufficient strength and rigidity can be exhibited in the thickness direction of the metal plate material.
