DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A handrail on-site processing apparatus 10 according to the present invention is for processing a handrail 11 made of synthetic resin into a shape suitable for the form of a mounting portion.

[0008] Therefore, the synthetic resin in the present invention is a thermoplastic synthetic resin, and other synthetic resins, for example, thermosetting synthetic resins are excluded. Further, in the present invention, the processing is mainly bending processing or modification processing of a bent shape.

The apparatus 10 of the present invention softens the processed part of the handrail 11 by heating, and this method has been conventionally performed. However, the present invention is characterized in that heat is applied only to a processing portion and deformation is not applied to other portions.

For this reason, in the apparatus 10 of the present invention, the surrounding member 12 surrounding the processing portion is an indispensable element. The surrounding member 12 is attached to the handrail 11 so as to surround a target processing portion. The attachment is performed by the attachment means 13. The space inside the attached surrounding member 12 constitutes a heating chamber 14 for heating the processing site. The surrounding member 12 itself has a ventilation structure capable of discharging the inside air when the internal pressure of the heating chamber 14 increases.

In the example shown in FIG. 1, the surrounding member 12 is formed in a bag shape from a substantially T-shaped or inverted triangular sheet-shaped material. In order to attach this so as to surround the processed part of the handrail 11, a T-shaped horizontal bar portion or an inverted triangular bottom portion is provided so as to be openable and closable, and a hook-and-loop fastener there (FIG. 1).
Mounting means 13 such as or a slide fastener (FIG. 3)
An opening / closing member that doubles as a member is provided to enable attachment.

By using a hook-and-loop fastener or a slide fastener or by tying it with a string, the opening edges on both sides are in close contact with the handrail 11 passed through the enclosing member 12, and air leakage can be prevented to some extent. . Thereby, the heated air can be sufficiently stored in the heating chamber. The heating chamber 14 in the present invention does not need to be airtight, but preferably has a function of storing hot air as described above.

As a ventilation structure for discharging the stored heated air to the outside, in the case of the embodiment, the air permeability of coarse cloth is used. In addition to heat-resistant cloth, it is naturally possible to provide a ventilation structure to a non-permeable material by opening a ventilation hole. Therefore, the surrounding member 12 is formed by using a metal or a heat-resistant resin. May be.

A heating blower 15 is combined with the surrounding member 12. The heating blower 15 includes a heater for heating the air, and a blower for pressure-feeding the air heated by the heating, and sends the heating air to the heating chamber 14 of the surrounding member 12. The heater of the heating blower 15 can be turned on and off, and after finishing the processing, if it is desired to fasten the fixing to a certain bending process quickly, the heater can be turned off to blow cool air (room temperature air) to promote cooling.

In the embodiment, a commercially available hair dryer is used as the heating blower 15 as it is. The hair dryer is suitable because the temperature can be selected between high and low, the amount of heat and air flow are sufficient, and the performance is stable as a home appliance. A heating dryer having a similar structure and used for general work is also suitable for the heating blower 15 in the present invention. 1 in the figure
Reference numeral 6 denotes a cord-like member that passes through the opening and closing edges on both sides, and is used for binding the opening edge to close as described above according to conditions such as a difference in the thickness of the handrail.

The enclosing member 12 and the heating blower 15 may be integrally formed from the beginning, or may have a structure in which separate members are connected as shown in the illustrated example. In the illustrated example, a connection port 17a is provided at the lower end of the T-shaped vertical bar portion or the apex portion of the inverted triangle, and the nozzle portion 17b of the hair dryer is connected thereto, and the fixing means 17 such as the hook-and-loop fastener is provided.
c and the surrounding member 12 and the heating blower 1
5 is integrated.

Further, according to the present invention, a jig 20 having support portions 18a and 18b for keeping the handrail 11 and the heating blower 15 in a fixed relationship during operation can be provided. The handrail 11 is mounted on left and right plate-like support portions 17 and 18. The support portions 18a and 18b have a groove 21 on which the handrail 11 is placed, and can be made foldable. In the figure, reference numeral 22 denotes a timer.

The handrail 11 targeted in the embodiment is, in the case of the embodiment, a rod-shaped material having a circular cross section having a diameter of 35φ, which is obtained by uniformly mixing a fine powder of wood powder with a thermoplastic resin and extruding the mixture. . On the other hand, when the heating chamber 14 was made airtight and hot air was blown by the heating blower 15,
It softened in less than 10 minutes at a temperature of 0 ° C., and could be bent into a desired curve.

At the time of bending, a mold can be used. An example is shown in FIG. The mold forms a concave form 23, a convex form 24 that gives an inner curve 25 corresponding to the corner 26a.
Etc. and those having different sizes (bending R) can be prepared. The handrail 11 processed by the apparatus shown in FIG. 5 is continuous as shown in FIG. The example of FIG. 6 shows a convex frame 24 ′ for giving a different shape to the handrail processing portion 27 that has been bent to a predetermined radius in advance. The convex frame 24 'is provided with a bulge 28 which bypasses a corner 26b of the wall.
Has an outer curve 27 '. See FIG.

Each of these molds 23, 24 and 24 'has a mold groove 29, into which the handrail 11 is fitted to give the final shape. When the formwork 23 is used, the handrail 11 is softened in advance by the apparatus 10 of the present invention, and then deformed by being applied to the formwork 23.

The handrail 11 is attached to an attachment site using a bracket 30. 26 at the installation site
a, when there is a protruding corner 26b, the handrail 11 is processed using the present invention apparatus 10 to perform processing adapted to the form. At this time, since the processing can be performed using the bracket 30 and the support base 31 while the handrail 11 is arranged near the mounting portion, a shape most suitable for the form at the site can be provided.

[0022]

Since the present invention is constructed and operates as described above, there is an effect that a handrail can be machined on site at an optimum shape for the form of the mounting portion. In particular, the heating chamber concentrates the heating on the processing area, and the processing quality can be further improved by jigs and the like. And it becomes a true continuous handrail.
