Description

Description: TECHNICAL FIELD The present invention relates to a glazing channel interposed between a sash frame and a glass fitted inside the sash frame, and a method of manufacturing the glazing channel.

(Prior art and its problems) Generally, a glazing channel made of a soft synthetic resin is interposed between a frame member of a glass shoji and glass.
When attaching the glass to the frame material, wrap the glazing channel around the glass in advance, and press the peripheral edge of the glass with the glazing channel attached to the fitting grooves of the vertical and horizontal stiles of the shoji. After that, the vertical and horizontal frames were framed.

However, the operation of winding the glazing channel around the periphery of the glass requires skill and is troublesome.

Since the cross section of the glazing channel is formed in a channel shape, it is necessary to arrange the middle piece E in the extrusion die D as shown in FIG. For this reason,
In addition to complicating the design of the extrusion die, the intermediate piece E receives a large resin pressure during extrusion, so that the die must be designed to maintain sufficient strength.

(Object of the Invention) The present invention solves the above-mentioned drawbacks, and in particular, can be easily and securely attached to a frame material in advance, and has a large glass supporting strength.
Moreover, it is an object of the present invention to provide a glazing channel that can be easily formed and a method of manufacturing the glazing channel.

(Means for Achieving the Object) In order to achieve the above object, the glazing channel according to the present invention is a glazing channel used in a channel shape state, and has a pair of side edges and a bottom edge when used. And a connecting portion for connecting each side edge and the bottom edge, and a glass contact tongue protruding inside the both side edges, and a pair of side edges and a bottom edge are formed from a hard synthetic resin. The connecting portion is formed of a soft synthetic resin, and the tongue is formed of a soft synthetic resin.

It is preferable that the glazing channel is developed and formed such that the pair of side edges, bottom edge, and connecting portion are continuous in a flat shape at the time of molding.

Further, the method of manufacturing the glazing channel is used in a channel shape state, and in a state of use, a pair of side edges and a bottom edge, and a connecting portion connecting the side edges and the bottom edge, and an inside of the side edges. A resin passage for forming a glazing channel having a glass contact tongue piece formed so as to protrude into a cross-sectional shape developed so that the side edge, the bottom edge, and the connection portion are continuous in a flat plate shape. A resin passage is formed in an extrusion molding die, a hard synthetic resin material is poured into a portion forming the side edge and the bottom edge of the resin passage, and a portion forming the connection portion and a glass contact tongue piece is formed. Is characterized by pouring a soft synthetic resin material and performing co-extrusion molding.

Hereinafter, the present invention will be described with reference to the drawings.

In FIG. 1, A indicates a frame material, B indicates a glazing channel, and C indicates glass.

The frame material A is a vertical frame or a horizontal frame of a glass shoji, and a glass fitting groove 1 is formed in a portion which is inside when the frame is assembled. A holding groove 2 is formed on the inner wall of the glass fitting groove 1.

Before the glazing channel B is mounted on the frame material A, as shown in FIG. 2, the pair of side edges, the bottom edge 4 and the connecting portion 5 are developed and formed so as to be continuous in a flat plate shape. And a pair of side edges 3, a bottom edge 4, a connecting portion 5 connecting the side edges 3 and the bottom edge 4, and the both side edges in a state of use. 3
And a tongue piece 6 for glass contact which is formed to protrude inward. The side edge 3 is formed to be narrower than the depth of the glass fitting groove 1 of the frame material A, and the bottom edge 4 is formed to be slightly smaller than the opening width of the glass fitting groove 1. In addition, side edge 3
On the outside of the fitting groove 1, two parallel ridges 7, 8 are formed, and the interval between the ridges 7, 8 is substantially the same as the groove width of the holding groove 2 on the inner wall of the fitting groove 1. . And the side edge 3
And the bottom edge 4 are formed of a hard synthetic resin,
The tongue piece 6 is formed of a soft synthetic resin.

When attaching the glass C to the frame material A using the glazing channel B having the above-described configuration, the glazing channel B is mounted in the glass fitting groove 1 of the frame material A in advance. In this case, the entire glazing channel B is bent into a U-shape from the connecting portion 5 and pushed into the glass fitting groove 1 from the opening side to be fitted therein, and the ridges 7 and 8 are retained on the inner wall of the fitting groove 1. Fit into groove 2. After that, the periphery of the glass C is fitted into the opening of the glazing channel B, the tip of the tongue 6 of the glazing channel B is brought into contact with the surface of the glass C, and the frame material A is framed.

As a method of mounting the glazing channel in the glass fitting groove, it is conceivable to slide and fit the glazing channel from the end of the glass fitting groove, but in this case, the sliding between the glazing channel and the frame member is considered. The resistance is large, labor is required for the sliding operation, and the dimensional tolerance with respect to the glass fitting groove is important, so that dimensional management is troublesome. However, in the case of the glazing channel B, the workability is good because the glazing channel B can be directly pushed into the fitting groove 1 of the frame material A from the opening side and fitted and mounted.

Further, both side edges 3 of the mounted glazing channel B are urged in the developing direction by the elasticity of the connecting portion 5 made of a soft synthetic resin, that is, in the direction in which the opening of the glazing channel B is expanded outward. For this reason, the ridges 7 and 8 are firmly fitted into the holding grooves 2 of the fitting grooves 1, and the glazing channels B are in close contact with the fitting grooves 1 so that they are difficult to come off, and the openings are in an expanded state. Since it is held, the work of fitting the peripheral portion of the glass C from the opening end can be easily and reliably performed.

Further, since the side edge 3 and the bottom edge 4 constituting the basic portion of the glazing channel B are both formed of a hard synthetic resin, the supporting strength for supporting the glass C is lower than that of the conventional glazing channel B made of a soft synthetic resin. And very big.

Next, the above-described glazing channel B in the developed state
As shown in FIG. 3, an extrusion molding machine in which a cooling water tank 11 is arranged at the rear of the extrusion molding die 10 connected to the extrusion molding machines 9a and 9b, and then a take-off machine 12 and a cutting machine 13 are arranged. Form by line.

As shown in FIG. 4, the extrusion die 10 is divided into a front die 10a and a rear die 10b.
b, a pair of side edges 3 (including the ridges 7 and 8), a bottom edge 4, a connecting portion 5 connecting the side edges 3 and the bottom edge 4, and a pair of the side edges 3 formed in a plate shape. A resin passage for forming a glass contacting tongue piece 6 formed to protrude inward;
A resin passage 14a having a cross-sectional shape developed so that the bottom edge 4 and the connecting portion 5 are connected in a flat plate shape is formed. A resin passage corresponding to the side edge 3 and the bottom edge 4 is formed in the front die 10a. It is preferable to form the resin supply path 15 and the resin supply path 15.

The front die 10a is connected to the horizontal extruder 9a, and the rear die 1
0b is connected to the vertical extruder 9b, the hopper 16 of the horizontal extruder 9a is filled with a hard synthetic resin material, and the hopper (not shown) of the vertical extruder 9b is filled with a soft synthetic resin material. In the co-extrusion molding line, first, the hard synthetic resin material melted from the horizontal extruder 9a is supplied to the side edge 3 and the bottom edge 4 of the front die 10a.
After pouring into the resin passage 14b corresponding to the vertical extruder 9
The molten soft synthetic resin material is extruded from b into the resin supply path 15 of the front die 10a. The soft synthetic resin material sent from the resin supply path 15 to the resin passage 14a of the rear die 10b is sent to the rear die 10, and is poured into the portions 16, 17 where the hard synthetic resin material was not poured in the front die 10a. . As a result, a hard synthetic resin material is applied to a portion (resin passage 14b) forming the side edge 3 and the bottom edge 4 of the resin passage.
Portion 1 forming the connecting portion 5 and the glass contact tongue piece 6
The soft synthetic resin material is poured into 6, 17 and is extruded from the die 10 in this state, and after being cooled and cured in a water bath,
The molded product of the glazing channel B is completed by being pulled by the take-off machine 12 and cut into a predetermined length.

(Effect of the Invention) According to the glazing channel according to claim (1), since the side edge and the bottom edge constituting the basic portion are both formed of a hard synthetic resin, the supporting strength for supporting the glass is the same as that of the conventional glazing channel. Is very large compared to the soft synthetic resin glazing channel.

Next, since the glazing channel according to claims (2) and (3) is developed in a flat plate as a whole, molding is easy. Also, when mounting glass using this glazing channel, it will take a process of mounting the glass after mounting the glazing channel on the frame material, so the glazing channel is mounted on the frame material in advance at the factory, The work of attaching the glass can be performed immediately on site and can be directly fitted into the glass fitting groove of the frame material from the opening side, so that the workability is very good.

Also, when the glazing channel is mounted on the frame material, the elasticity of the connecting portion made of the soft synthetic resin urges the side edges on both sides in the developing direction, that is, in the direction in which the opening of the glazing channel is expanded outward. Is done. For this reason, the ridge is strongly fitted into the holding groove of the fitting groove, and the glazing channel is in close contact with the frame material and is hard to be removed, and the opening is held in the expanded state. Thus, the work of fitting the peripheral portion of the glass can be easily and reliably performed.

Furthermore, according to the method for manufacturing a glazing channel according to claim (4), the glazing channel can be molded in an unfolded state, so that the intermediate piece is not required, and the influence of the resin pressure during molding on the strength of the intermediate piece is reduced. Since there is no need to consider, the design of the molding die can be simplified, the cost can be kept low, and the glazing channel can be easily extruded.
