The present invention relates to a method of manufacturing a frame with a handle and an edge member.

(Prior Art and Problems to be Solved by the Invention) In the past, handles for doors of furniture, kitchen appliances, etc., sliding doors, etc. were made by attaching the handle to the frame material after forming the frame of the door, etc., or by attaching the handle to the frame material etc. A predetermined recess is provided in the recess, and the handle is formed by attaching a metal fitting to the recess. Therefore, in both cases, there is the trouble of having to attach the handle later, which lowers work efficiency.Especially in the former case, not only can the protruding handle get in the way, but also the eight handles There was also the problem that the appearance of doors etc. was spoiled. On the other hand, in the latter case as well, the handle lacks aesthetic integrity with the surrounding parts, so it has not been possible to eliminate the aesthetically unnatural appearance of the handle.

The present invention provides an outer cover in which a protruding recess for a handle is formed;
Basically, after separately manufacturing a core material provided with a recess for forming a handle, the core material is covered with an outer covering so that the protruding recess for the handle fits into the recess for the handle. , (a) solve the above-mentioned problems with the handle, and ensure that the handle can be held securely, and (b)
The core material ensures the strength of the frame and edge members, (c) the outer cover improves the appearance of the frame and edge members as a whole, and (d) moreover, when covering the core material with the outer cover, the outer cover The object of the present invention is to provide a method for manufacturing a frame and edge member with a handle, in which a unique device is devised so that a protruding recess for a handle on a cover can be fitted into a recess for a handle on a core material without difficulty.

(Means for Solving the Problems) In order to solve the above problems, the method for manufacturing a frame with a handle and edge member according to the present invention (hereinafter referred to as the manufacturing method) employs the following means. Note that in this specification, the term "frame/edge member" is used to collectively refer to the frame member and the edge member.

The manufacturing method according to the present invention is used to manufacture a frame/edge member with a handle, in which a core material 2 is covered with an outer cover 1, and an appropriate number of handles 7 each having an inclined recess are provided at a required portion of the front surface. :
An extruded synthetic resin hollow molded body 120 having a rectangular tube shape and having continuous kerfs 19 extending over its entire length is provided at a required portion with a surface that is inclined with respect to the side surface that comes into contact with the front surface 15 of the hollow molded body 12. After opening the cutout 119 and placing the concave mold 18 provided so that the concave part 16 opens forward, a convex mold heated to a required temperature is placed in a portion of the hollow molded body 12 facing the concave concave part 16. 21 to produce a pull protrusion recess 17 that projects obliquely toward the cut groove 19, and then remove the concave mold 18 from the hollow molded body 12 to produce the outer cover 1; on the other hand, Hollow molded body 1
The front part 15 of the hollow molded body of the bag supply material 22 made of wood material or reinforced synthetic resin foam is loaded into the bag in substantially close contact with the interior of the bag supply material 22.
The inclined concave portion l of the concave mold 18 is formed on the surface portion 23 on the side that comes into contact with the concave mold 18.
The core material 2 is manufactured by providing a recess 25 for the handle with the same shape as G; by the elastic restoring action of the outer sheath 1 opened at the groove 19, the outer sheath is inserted into the recess 25 for the handle of the core material 2. This is characterized in that the core material 2 is covered with the outer cover 1 so that the protruding recess 17 for the handle 1 is fitted into the core material 2.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 illustrates an outer cover 1 and a core material 2 used in carrying out the manufacturing method according to the present invention, and FIG. 2 shows a frame/edge member 3 with a handle obtained by the manufacturing method according to the present invention. The frame/edge member 3 with a handle is used, for example, as a frame material for forming a door 6 of a kitchen appliance 5 shown in FIG. It is provided with a handle 7 consisting of a recessed part.

The outer cover 1 has a rectangular cylindrical shape with a relatively wide ridge cut out over its entire length, and its entire length is the same as that of the door 6.
After forming an extruded hollow molded body 12 made of an elastic synthetic resin such as hard vinyl chloride, the length of which is the total length of the upper and lower frame members 8 and 9 and the left and right side frame members 10 and 11, the hollow molding is performed. A portion of the frame material forming portion 13 on the body 12 near the end of the front surface portion 15 is directed toward the inner edge portion 14 of the forming portion 13 (cut groove 1
9) to form a protruding recess 17 for the handle. In order to form the protruding recess I7 for the pull handle, first, as shown in FIG. The concave mold 18 is placed in a desired portion of the hollow molded body 12 by opening the cut groove 19 of the hollow molded body 12. Thereafter, the part of the hollow molded body 12 where the concave mold 18 is placed is supported by the V block 20 with the front face 15 of the hollow molded body 12 facing upward as shown in FIG. This is done by pushing the mold 21 toward the recess 16, then pulling out the convex mold 21, and removing the concave mold 18 from the hollow molded body 12 by cutting the grooves 19 again.

In this embodiment, the reason why the cut groove 19 is formed relatively wide is that the cut groove portion is also used as a decorative board mounting portion, as will be described later. Note that when forming the protruding recess 17 for the pull handle, there is a risk that the synthetic resin will be stretched and whitening will occur on the recess surface, but if it is particularly necessary, the outer cover may be removed after forming the protruding recess 17 for the handle. 1
It is best to paint the entire exterior surface.

As shown in FIG. 1, the core material 2 is formed using a reinforced synthetic resin foam reinforced with wood materials, fibers, etc., and is inserted into the hollow molded body 12 in a substantially intimate state. The concave mold 18 is attached to the front part 23 of the bag supply material 22 (the surface part on the side that comes into contact with the internal work 5 of the hollow molded body 12), which is formed in the shape and size.
It is formed by providing a pull recess 25 having the same shape as the inclined recess 16. Note that the core material 2 has a second groove in a portion corresponding to the cut groove 19 portion of the hollow jacket 12.
As shown in the figure, for fitting the peripheral edge 27 of the decorative board 26 and fixing the peripheral edge 27 via the clamping pieces 28,
A notch 29 is provided.

By covering the core material 2 manufactured in this way with the outer cover 1, a frame with a handle as shown in FIG.
When manufacturing the edge member 3, the outer cover 1 is opened at its kerf 19 as shown in FIG. The core material 2 is sandwiched between the lower edge portion 31 of the body l, and in this state, the core material 2 is pushed in the direction of the arrow F as shown in FIGS. Due to the elastic restoring action, as shown in FIG. 2, the outer cover 1 covers the core 2 with the pull protruding recess 17 of the outer cover 1 fitted into the pull recess 25 of the core 2. Eggplant.

Note that when pushing the core material 2 into the outer cover 1, the lower edge 3o of the pull protruding recess 17 in the outer cover 1 is inserted into the core front part 23.
When the outer cover 1 is located at the proximal upper edge 32 of the pull recess 25, the opening state of the outer cover 1 is the largest, but if the core material 2 is pushed further, the pull will open as shown in FIG. The lower end portion 33 of the protruding recess 17 gradually enters the pull recess 25, so that the open state of the outer cover 1 becomes smaller, and the outer cover 1 maintains its elastic restoring action without being subjected to unreasonable deformation. The core material 2 will be covered by this.

Incidentally, assuming that a frame/edge member with a handle is manufactured, as shown in FIG. 9, which has a rectangular handle a recessed in the thickness direction, The depth of the recess e is set to be constant over its entire width (the depth of the pull protruding recess 17 in the outer cover l according to the present invention is the depth of the protruding recess 17 of the front surface of the outer cover 1). (See Figure 1). Therefore, when covering the core material d with the outer cover C having such a protruding concave portion e for the handle, as shown in FIG.
The opening angle of the outer cover C continues to increase until the protruding recess e for the handle fits into the recess f for the handle of the core member d.

Therefore, just before the pull protruding recess e fits into the pull recess r, the front part g and the rear part of the outer cover C are deformed beyond the elastic limit at the base end part j+J. It is no longer possible to expect the covering of the core material d by the elastic restoring action of the outer covering C, and therefore, it is no longer possible to obtain the desired frame and edge member with a handle for covering the outer covering as shown in Fig. 9. That will happen.

On the other hand, in the present invention, the pull recess 2 of the core material 2
5 and the pull protruding recess 17 of the outer cover 1 are both formed to be inclined, so such problems do not arise. Moreover, since the formed handle consists of an inclined recess, unlike the case where the handle is formed in a rectangular shape in the thickness direction of the frame/edge member, as shown in FIG.
A stable clue will result in a state being obtained.

Using the handle frame/edge member 3 manufactured in this way, the fourth
In order to form the door 6 as shown in the figure, it is necessary to bend the handle frame/edge member 3 from one side plate 35 side to the other side plate 36 as shown by the dashed line in FIG. ,
After forming a door frame 39 by providing a V-shaped groove 37 having an angle of 90 degrees and cutting the ends diagonally, bending the whole into a rectangle and joining the ends as shown in FIG. The decorative board 40 is attached to the door frame 39 in the manner described above.

(Effects of the Invention) The present invention separately manufactures an outer cover having an inclined protruding recess for a handle and a core member having an inclined recess for a handle, and the protruding recess for a handle fits into the recess for a handle. Since the core material is covered by the outer sheath in the open state, (a) the core material guarantees strength, (b) the outer sheath improves the appearance of the frame/wire member as a whole, and ( c) The handle part is formed as a concave part and is completely integrated with the frame/edge member, and there is no aesthetic unnaturalness that would occur if the handle was added later as in the past; (d) Also, the handle part It is possible to manufacture a frame/edge member with a handle that has excellent features such as ensuring reliable handling.

Moreover, as explained based on FIGS. 7 and 8, the core material can be covered with the outer covering by effectively utilizing the elastic restoring action of the outer covering without causing unreasonable deformation of the outer covering. Because of this, it is possible to easily manufacture such a frame/edge member with a handle.
