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) Doors of furniture, kitchen appliances, etc., pulls of sliding doors, etc.
After forming a frame such as a door, a handle is attached to the frame material or the like, or a predetermined recess is provided in the frame material and a handle fitting is attached to the recess. Therefore, in either case, there is the trouble of having to attach the handle later, which lowers work efficiency. In the former case in particular, not only does the protruding handle get in the way, but also the handle does not close to the door. There were also problems that impaired the appearance. On the other hand, even in the latter case, the handle lacks aesthetic integrity with the surrounding parts, so it has not been possible to eliminate the unnatural appearance of the handle.

In the present invention, after separately manufacturing an outer cover in which a protruding recess for a pull is formed and a core material in which a recess for forming a pull is provided, the protruding recess for a pull is fitted into the recess for a pull. Based on the principle of covering the core material with the outer cover so that the core material remains in the same state, (a) it solves the above-mentioned problems with the handle and ensures that the handle can be held securely, and (b) the core material (c) The outer cover improves the appearance of the frame/edge member as a whole, and (d) Moreover, when covering the core material with the outer cover, it is possible to The object of the present invention is to provide a method for manufacturing a frame and edge member with a handle, which is uniquely devised so that the protruding recess for the handle of the cover can be fitted into the recess for the handle of the core material without any force.

(Means for Solving the Problems) In order to solve the above problems, a method for manufacturing a frame with a handle and an edge member according to the present invention (hereinafter referred to as a manufacturing method)
shall adopt the following measures. 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. : The hollow molded body 1 is placed at a desired portion of the extruded synthetic resin hollow molded body 12 in the shape of a rectangular tube, in which continuous kerfs 19 are provided over the entire length.
After opening the groove 19 and installing the concave mold 18, which is provided so that the concave part 16 which is inclined with respect to the surface part on the side that contacts the front part 15 of the hollow molded body 12 opens forward, the concave mold in the hollow molded body 12 is By pushing the convex die 21 heated to the required temperature into the area facing the concave part 16, the protruding concave part 17 for the handle that protrudes in an inclined manner toward the cut groove 19 is manufactured, and then the concave die 18 is hollow-molded. Remove the outer cover 1 from the body 12
On the other hand, on the surface portion 23 of the packaging material 22 made of wood material or reinforced synthetic resin foam, which is packed in the hollow molded body 12 in a substantially intimate state, the surface portion 23 is in contact with the front face portion 15 of the hollow molded body. The core material 2 is manufactured by providing a pull recess 25 having the same shape as the inclined recess 16 of the recess 18; The core material 2 is covered with the outer sheath 1 so that the pull protruding recess 17 of the outer sheath 1 fits into the pull recess 25 of the material 2.

(Example) Examples 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 with a handle and an edge obtained by the manufacturing method of the present invention. This is an example of the member 3, and the frame/edge member 3 with a handle is, for example, a kitchen utensil 5 shown in FIG.
It is used as a frame material for forming a door 6, and is provided with a handle 7 consisting of an inclined recess at a required portion of the front surface.

The outer cover 1 has a rectangular cylindrical shape with one ridge section cut out relatively wide over its entire length, and its entire length extends from the upper and lower frame members 8 and 9 of the door 6, and the left and right side frame members. After forming an extruded hollow molded body 12 made of an elastic synthetic resin such as hard vinyl chloride and having a total length of 10 and 11, the front part 15 of the frame material forming part 13 above the hollow molded body 12 is formed. toward the inner edge 14 side of the forming portion 13 (cut groove 1
9) is recessed at an angle of about 45 degrees to form a protruding recess 17 for the handle. To form the protruding recessed part 17 for the handle, first, as shown in FIG. Concave type 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 in which 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 convex mold 21 heated to a predetermined temperature toward the recess 16, and then pulling out the convex mold 21, opening the kerf 19 again, and removing the concave mold 18 from the hollow molded body 12. 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. It is best to finish the entire exterior surface of 1 with paint.

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 delivered in the hollow molded body 12 in a substantially intimate state. The inclined concave portion 16 of the concave mold 18 is formed on the front surface portion (the surface portion on the side that contacts the hollow molded body front portion 15) of the packaging material 22 which has been formed in the shape and dimensions.
It is formed by providing a pull recess 25 having the same shape. It should be noted that the core material 2 has, in a portion corresponding to the cut groove 19 portion of the hollow outer cover 12,
As shown in FIG. 2, a notch 29 is provided into which the peripheral edge 27 of the decorative board 26 is inserted and to which the peripheral edge 27 is fixed via the clamping piece 28.

Then, by covering the core material 2 manufactured in this way with the outer cover 1, a frame/edge member 3 with a handle as shown in FIG. 2 is manufactured. As shown in the figure, the outer cover 1 is opened at its kerf 19, and the core material 2 is sandwiched between the lower edge 30 of the pull protruding recess 17 and the lower edge portion 31 of the outer cover 1, as shown in FIG. with and without,
In this state, the core material 2 is pushed in the direction of the arrow F as shown in FIGS. The core material 2 covers the outer cover 1 with the handle protruding recess 17 of the outer cover 1 being fitted into the outer cover 1.

Note that when pushing the core material 2 into the outer cover 1, the lower edge 30 of the protruding recess 17 for the pull in the outer cover 1 is located at the upper end edge 32 of the proximal side of the recess 25 for the pull in the front part 23 of the core. In this case, the opening state of the outer cover 1 is the largest, but when the core material 2 is further pushed in, the lower end portion 33 of the protruding recess 17 for the pull handle is inserted into the recess 25 for the pull handle, as shown in FIG. As a result, the open state of the outer cover 1 becomes smaller, and the outer cover 1 covers the core material 2 by its elastic restoring action without being subjected to excessive deformation.

Incidentally, assuming that a frame/edge member b with a handle is manufactured which has a handle a recessed in the thickness direction so as to have a rectangular shape as shown in FIG. The depth of the recess e is
The projecting recess 1 for the handle in the outer cover 1 according to the present invention is set to be constant over its entire width.
7 becomes gradually shallower toward the proximal end 34 of the front surface of the outer cover 1 (see FIG. 1). Therefore, when it is intended to cover the core material d with the outer cover c having such a protruding recess e for the pull handle, the protruding recess e for the handle fits into the recess f for the handle of the core material d, as shown in FIG. Until it jams in, the opening angle of the outer cover c continues to increase. Therefore, in the state immediately before the protruding recess e for the handle fits into the recess f for the handle, the front part g and the rear part h of the outer cover c are
is deformed beyond its elastic limit at its proximal end portions i and j, and it is no longer expected that the core material d will be covered by the elastic restoring action of the outer covering c, and therefore, as shown in FIG. Therefore, it is not possible to obtain a frame/edge member with a handle for covering the outer cover.

On the other hand, in the present invention, since the pull recess 25 of the core material 2 and the pull pull protruding recess 17 of the outer cover 1 are both formed to be inclined, such problems do not occur. . Moreover, since the formed handle consists of an inclined concave portion, unlike the case where the handle is formed in a rectangular shape and concave in the thickness direction of the frame/edge member, as shown in FIG. This will be obtained.

In order to form a door 6 as shown in FIG. 4 using the frame and edge member 3 with a handle manufactured in this way, the frame and edge member 3 with a handle should be bent at one point in FIG. As shown by the chain line, a V-shaped groove 37 having an angle of 90 degrees is provided from one side plate 35 side to the other side plate 36, and the end is cut diagonally, and the whole is rectangular as shown in FIG. After the door frame 39 is formed by bending the door frame 39 and joining the ends, 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 structure is such that the core material is covered by the outer cover in the open state, (a) the core material guarantees strength, (b) the outer cover improves the appearance of the frame and edge members 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 be seen 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 shell by effectively utilizing the elastic restoring action of the outer shell without causing unreasonable deformation of the outer shell. Because of this, it is possible to easily manufacture such a frame/edge member with a handle.
