Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail having a non-slip function when held and used, and a simple manufacturing method thereof.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 8-326257 discloses a handrail (product) having a non-slip function for holding and using.
The manufacturing method thereof is the same as that disclosed in JP-A-8-199755.
-258184, 9-1619 and 9-41
No. 611 is proposed respectively.

In addition, since the publicly known inventions of the manufacturing method are basically the same, the manufacturing method of the handrail with non-slip is as follows, taking Japanese Patent Laid-Open No. 8-199755 as a representative example.
While the hollow member (8) is passing through the first mold (2) to the outer peripheral surface of the hard synthetic resin hollow member (8), the adhered layer (9) made of the synthetic resin from the first extruder (1). ) Is pressure-molded, and subsequently while passing through the second mold (4), the same effective synthetic resin from the second extrusion molding machine (3) is applied to a part of the outer peripheral surface of the adherend layer (9). By the shutter elevating mold (5) of the variable drive device (6), a thick projection portion (10) and a thin concave arc portion (11) are formed alternately as a concavo-convex film portion (12), and then a cooling water tank ( 13) to be cooled and solidified, and finally cut with a standard length cutting machine (15).

[0004]

However, such a manufacturing method is, so to speak, an extrusion molding method for forming a hollow triple tube, and the synthetic resin of the first mold (2) and the second mold (4) are synthesized. If it is not of the same quality as the resin, it cannot be molded as the desired handrail with non-slip, and the first and second molds (2) and (4) and the first and second extrusion molding machines (1 ) (3), the variable drive device (6), and the shutter raising and lowering mold (5) that is moved up and down by the variable drive device (6).

Further, by controlling the raising / lowering operation speed of the shutter raising / lowering die (5), the uneven coating portion (12) is formed.
Even if it is possible to adjust the interval pitch at which the thick protrusions (10) and the thin concave arcs (11) in (1) are alternated, it is not possible to change the interval pitch to at random (uneven).

Further, the thick protrusions (10) and the thin concave arc portions (11) are scattered and distributed in two rows along the longitudinal direction of the hollow member (8), or alternate staggering in the two rows. It is extremely impossible to disperse in a scattered state or to disperse in a localized manner, and it is not possible to obtain a wide variety of handrails with non-slip suitable for the construction site.

A product extruded by the above-mentioned manufacturing method-a handrail is also composed of a synthetic resin of the same effect,
If it becomes long, it will be easily bent and deformed, and it will be difficult to stably and firmly combine and integrate it with the handrail receiving bracket. If the metal tube body (16) is inserted into the hollow member (8) to reinforce the hollow member (8), not only the separate insertion work is required, but also the weight is unnecessarily increased.

Further, the above handrail, which is an extruded product made of synthetic resin, cannot be bent in construction, and a large number of joints are required to obtain the bent construction state, and moreover, As a result of the exposed joint, it becomes very unsightly, and there is also a problem that the construction site is restricted.

[0009]

DISCLOSURE OF THE INVENTION The present invention intends to radically solve such problems, and in view of the structure of the handrail, a plurality of stators having a large-diameter head having a convex curved surface are provided. , The cover tube made of synthetic resin elastomer or soft synthetic resin of a certain thickness is inserted into the rigid core body that is planted as a scattered distribution along the longitudinal direction, and integrated, and sliding based on the head of the stator is performed. Characterized by exposing the stop hump,

In addition, as a method of manufacturing the above handrail, a rigid core body cut into a certain length required for construction,

A cover tube extruded from a synthetic resin elastomer or a soft synthetic resin to have an inner diameter slightly smaller than the outer diameter of the core is prepared.

After a plurality of stators each having a large-diameter head having a convex curved surface are planted in a scattered distribution state at an appropriate interval pitch along the longitudinal direction of the core,

The slippery hump corresponding to the head of the stator is exposed by forcibly inserting the cover tube into the core.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the drawings. First, FIGS. 1 to 5 show a straight type handrail (H) as a first embodiment of the present invention.
(10) is a rigid core made of a metal tube such as a stainless steel tube or an aluminum extruded tube having a constant outer diameter (D) (for example, about 25 mm) and a thickness (T) (for example, about 1-2 mm). , Is pre-cut to a certain length (L1) (for example, about 40 to 80 cm) required for construction.

(11) is an entire line along the longitudinal direction of the core body (10) and has an appropriate pitch (P).
When the core body (10) is made of a relatively soft extruded aluminum tube, which is a plurality of stator planting holes formed in a scattered distribution state for maintaining However, it does not matter even if this is bored as a stupid hole.

(A) is a plurality of stators to be planted in each planting hole (11) of the core body (10), and a screw shaft portion (12a) corresponding to the planting hole (11),
A small screw (12) having a head portion (12b) having a convex curved surface with a diameter larger than this is adopted.

The screw shaft portion (12a) of the machine screw (12) is a planting hole (screw hole) of the core body (10).
It is screwed into (11) and integrated, and the same large head (1
2b) protrudes from the outer peripheral surface of the core body (10). The constant height (h) overhanging is, for example, about 2
It is 4 mm.

However, when the core body (10) is made of an aluminum extruded tube as described above, its planting hole (stupid hole) (1
The screw shaft portion (12a) of the small screw (12) can be planted and fixed to 1) like tapping.

Further, as a stator (A) replacing the machine screw (12), a rivet (13) made of a hard synthetic resin as shown in FIG. 7 is adopted, and a fixing hole (11) for the stator is provided. Alternatively, the core body (10) may be provided as a fool hole. Since the wedge leg (13a) of the rivet (13) is provided with the split groove (14), the core body (10) has a planting hole (stupid hole) (11) so that the wedge groove (14) is forcibly contracted and deformed. ), The wedge leg (13a) is fixed in the retaining state by the restoring and expanding force, and the large-diameter head (13b) forming the convex curved surface of the rivet (13) is also the core body (10). Will protrude from the outer peripheral surface.

According to this, the rivet (13) can be inserted into the planting hole (fool hole) (11) of the core body (10) by pressing with the fingers, and the small screw (1)
Since it does not require a tool such as a screwdriver as in 2) and its screwing and turning operation, it becomes more and more advantageous for the workability of planting on the core body (10).

In this respect, the machine screw (12) of FIGS. 1 to 3 and FIG.
The rivet (13) has a large head (12b)
Although (13b) has a circular shape when viewed from the front, as shown in FIG. 8, the large-diameter head (13b) of the rivet (13) has a constant length (along the circumferential direction of the core body (10) ( L2) may be formed into a substantially elliptical shape as viewed from the front, and then the anti-slip hump described below should be expressed as a corresponding elliptical shape along the circumferential direction of the handrail (H). become.

Further, a solid wood or laminated wood round bar as shown in FIG. 9 is adopted as the core body (10), and the stator (A) is used as a tapping screw (15). The screw shaft (15a) of () is directly screwed into the core body (wooden round bar) (10), so that the large diameter head portion of the tapping screw (15) extends from the outer peripheral surface of the core body (10). It is also possible to keep (15b) in a protruding state.

On the other hand, (16) is a cover tube which is entirely passed through the core body (10), and is made of thermoplastic synthetic resin elastomer or soft synthetic resin and has an inner diameter (d) of the core body. It is preliminarily extruded with a size slightly smaller than the outer diameter (D) of (10). Moreover, the cover tube (16) has a constant thickness (t) of, for example, about 3 to 4 mm and is dimensioned to be considerably thicker than the thickness (T) of the core body (10).

In this case, the cover tube (16) is made of a thermoplastic thermoplastic synthetic resin elastomer (trade name: Sumitomo TPE) recycled material and a virgin material. The layer (16a) is formed by extrusion into a hollow double-tube structure in which the virgin material is an ultrathin semi-rigid outer skin layer (16b), and the outer skin layer (16b) has a single colored color or the one shown in FIG. It is preferable to apply a colored pattern (17) such as a wood grain pattern or an abstract pattern.

Then, the cover tube (1) whose overall thickness (t) is thicker than the thickness (T) of the core body (10).
6) can be mass-produced at low cost by using recycled materials together with the moderate elasticity of the polyolefin-based thermoplastic synthetic resin elastomer, and can give a soft feeling that is comfortable to hold and use. There is. Further, based on the excellent heat resistance, cold resistance and weather resistance of the synthetic resin elastomer, it is possible to obtain a handrail (H) that can be used not only indoors but also outdoors.

Since the inner diameter (d) of the cover tube (16) is slightly smaller than the outer diameter (D) of the core body (10), it is inserted into the core body (10). In this case, the outer peripheral surface of the core body (10) is dampened and wiped with water, and the cover tube (16) is manually attached to the core body (16) under the condition that it is received as shown in FIG. 1
You can force it into 0).

Then, the cover tube (16) slides on the outer peripheral surface of the core body (10) due to its elasticity, and the cover tube (16) is fixed to and integrated with the core body (10) by the restoring contracting force of its expansion. Will be changed. At that time, a large-diameter head portion (12b) (1) of the stator (A) preliminarily implanted in the core body (10).
3b) and (15b) project from the outer peripheral surface of the core body (10) as convex curved surfaces, so that the cover tube (1
6) is not received, and the core body (1
0) can be totally threaded.

In the state where the insertion is completed, as is apparent from FIGS. 1 to 3, the cover tube (16) is in close contact with the heads (12b) (13b) (15b) of the stator (A), The hump (1) is exposed only in the portion corresponding to the position (1) as a non-slip hump (18) based on the convex curved surface of the head (12b) (13b) (15b).
The corrugated pattern is alternated with dimples (19) which are relatively depressed with respect to 8). Moreover, the hump (1
Since 8) is scatteredly distributed, it is also useful for preventing the cover tube (16) from slipping against the core body (10) and preventing the core tube from slipping out.

In this respect, if the constant length (L1) required for construction is relatively short as the numerical value (about 40 to 80 cm) exemplified above, the degree to which dampening water is applied to the core body (10) However, the cover tube (16) can be inserted and integrated, but when the fixed length (L1) becomes longer than about 1 m, the cover tube (16) is heated to a preliminary state capable of promoting expansion. , The one end of the opening of the core body (10) is airtightly received and fixed, and the cover tube (16) is pushed from the other end of the opening of the core body (10), and at that time, the other end of the opening of the core body (10) Portion of the core tube (16) is fed by pressure to the inside of the cover tube (16), and the cover tube (16) in the preheated state is expanded by the internal pressure of the air. Through, and finally Over tubes (16) may be a natural cooling or forced cooling. By adopting such a method, the cover tube (16) can be passed through the core body (10) as a whole up to a constant length (L1) of about 4 m by manual operation without any difficulty.

In any case, the anti-slip hump (1
It is preferable that the adjacent pitches (P) of 8) are approximately evenly sized so as to partition the fingers of the hand to be gripped, but of the stator (A) that generates the hump (18). Since the planting position can be adjusted freely in advance, the hump (18) may be set to be at random (uneven) in the interval pitch (P) so that the humps (18) are locally and scatteredly distributed.

Further, the machine screw (12) and the rivet (1)
3), the stator (A) such as the tapping screw (15) has its head (12b) depending on the outer diameter (D) of the core (10).
It is possible to freely select and use the one having the changed outer diameter size including (13b) and (15b).

Further, in FIGS. 1 to 3, the humps (18) are shown in a state of interspersed distribution in a row along the longitudinal direction of the handrail (H), which is suggested from FIGS. And the row of humps (18) and a constant crossing angle (α)
It is also possible to expose another row of humps (18) that keeps from the handrail (H). At that time, the two rows of humps (18) and (18) may be phase-changed in an alternating zigzag state, and a variety of handrails (H) corresponding to the construction site can be easily obtained by such selection. be able to.
