Description of the Related Art Insulated doors are provided at the refrigerator compartment, freezer compartment, and vegetable compartment entrance of a refrigerator. Needless to say, the reason why these doors adopt the heat insulating structure is to keep cool. However, the heat insulating structure results in a considerable increase in the thickness of the door itself. A handle for opening and closing the door is attached to the panel surface of the heat-insulating door. In the past, many of these handles had a structure in which the grip part protruded from the panel surface.However, in recent years, most of the advantageous handles have been buried in a sufficiently thick insulated door by utilizing space, and the panel surface and Many are almost the same. Usually, the handle is made of a base material forming a fixing fixture attached to the inside of the door outer plate, a handle main body fixed to the base material, and a hard resin material which keeps an aesthetic appearance outside the handle main body. It is composed of three element parts of a decorative material, and these element parts are assembled to form a handle. [0004] The above-mentioned handle is satisfactory in operability and satisfactory in keeping the aesthetic appearance of the refrigerator-freezer, but has the following problems.
That is, this handle consists of three materials: base material, foam material and decorative material.
It is made up of element parts, each of which requires a lot of cost and makes the handle expensive. Also, it is necessary to assemble a plurality of element parts, sometimes it takes time to fit,
The time spent on this is lengthened and waste increases. Furthermore, although there is a slight gap between the element parts, the element parts rub against each other during the grip operation, and an unpleasant squeak sound is generated. SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator handle device which can be manufactured very inexpensively, and saves the labor for fitting the component parts to reduce the number of assembling steps. [0006] In order to achieve the above object, the present invention comprises a hard resin-made handle held on a door sheet made of a steel plate, and the door sheet is vertically inserted into the heat insulating wall. And a second edge extending vertically following the curved surface of the recess and a first edge extending vertically flush with the sheet surface of the door sheet, and A sickle-shaped through hole is formed along the curved surface of the recess, and a handle made of a single element is held in the through hole so as to pass between the first edge and the second edge. It is assumed that. Further, the present invention has a rib having a handle extending from the inner main body toward the inner surface of the outer decorative body and a holding portion provided adjacent to the outer surface of the pocket portion of the inner main body. And the handle is held such that the first edge of the door sheet is sandwiched between the door sheet and the second edge of the door sheet is sandwiched between the outer surface of the inner body and the holding portion. Things. Embodiments of the present invention will be described below with reference to the drawings. In FIG. 4, the refrigerator has a box-shaped main body 1 configured as a heat insulating wall on both sides, a back surface, a ceiling surface, and a bottom surface excluding the front surface having the entire area opened. The main body 1 is formed by filling a heat insulating material such as urethane foam between an outer box made of a steel plate and an inner box made of a hard resin material.
The interior of the main body 1 is partitioned into independent refrigerator compartments, freezer compartments, and vegetable compartments (neither is shown) by upper and lower partition walls (not shown) which are filled with a heat insulating material. ing. Further, the front opening of the uppermost refrigerating compartment is sealed by a highly airtight, rotary type heat insulating door 2. The freezer compartment below the refrigerating compartment is provided with highly airtight drawer-type insulated doors 3a and 3b (the freezer compartment of the present embodiment has two upper and lower stages), and the vegetable compartment below the freezer compartment is airtight. Each of them is hermetically sealed by a drawer-type heat insulating door 4 having a high height. Further, a handle 5 is provided near the left side of the heat insulating door 2 of the refrigerator compartment 2 in the drawing. As shown in FIG. 1, the handle 5 has a heat insulating door 2 having a sufficient thickness except for a part.
Embedded inside. The heat insulating door 2 of the present embodiment includes a door sheet 6 made of a thin steel plate, a door panel 7 made of a hard resin material, and a heat insulating material 8 such as urethane foam filled between the door sheet 6 and the door panel 7. It is composed of A recess 9 is formed in the door sheet 6 so as to bend inward from the sheet surface. The recess 9 extends along the handle 5 while maintaining a vertically curved surface (see FIG. 4). Further, a sickle-shaped through hole 10 is formed in the door sheet 6 along a curved surface extending vertically of the recess 9. The through hole 10 accommodates an inner main body of the handle 5 described later in detail. Also,
The door sheet 6 has a first edge 11 extending vertically while keeping the same level as the sheet surface of the door sheet 6, and a second edge 12 extending vertically following the curved surface of the recess 9. The first and second edges 11 and 12 are for holding the handle 5 in a predetermined position in cooperation with the ribs and holding portions of the handle 5 described in detail later. FIGS. 2 (a) and 2 (b) and FIG. 3 (a)
(B) The handle 5 according to the present embodiment will be described with reference to (c). 2A and 2B, the handle 5 has an outer decorative body 14 placed on the outside of the door sheet 6 which defines the outside of the heat insulating wall, and an inner side arranged inside the heat insulating wall of the door sheet 6. And a main body 15. The outer decorative body 14 and the inner main body 15 are integrally formed using a hard resin material. 3 (a), 3 (b) and 3 (c), the outer decorative body 14 has an outer surface 16 exposed to the outside and a flat inner surface 17 abutting on the door sheet 6. This inner surface 17
A plurality of ribs 18 extend from the inner body 15 toward the inner surface 17. The first edge 11 of the door sheet 6 is sandwiched between the inner surface 17 and the ribs 18 (see FIG. 1). The outer decorative body 14 is held. On the other hand, a pocket portion 19 having a U-shaped cross section is formed in the central portion in the longitudinal direction of the inner main body 15 so as to secure a size large enough for a user to put all fingers except thumb. Further, a curved outer surface 20 is formed in the inner main body 15 so as to contact the door sheet 6 following the pocket portion 19. Immediately adjacent to the outer surface 20, a plurality of holding parts 2
1 is provided, and the second edge 12 of the door sheet 6 is sandwiched between the outer surface 20 and the holding portion 21 (FIG. 1).
), The inner body 15 of the handle 5 is held. Accordingly, the handle 5 is attached by pushing the handle 5 toward the end of the heat insulating door 2 while sandwiching the first edge 11 between the inner surface 17 of the outer decorative body 14 and the rib 18 of the inner body 15. Then, while returning the handle 5 to the center direction, the second between the outer surface 20 of the inner body 15 and the holding portion 21
Is fixed by sandwiching the edge 12 thereof. At the position where the handle 5 is fixed, the pocket 19 of the handle 5 and the recess 9 of the door sheet 6 are connected, and the handle device as shown in FIG. 1 is completed. Thereafter, the handle 5 is firmly fixed by the heat insulating material 8 surrounding the inner main body 15 by foaming the urethane foam forming the heat insulating wall. In the gripping device constructed as described above, only the grip 5 which is a single element component needs to be formed, and there is no need to form other grip components, and it is extremely inexpensive. In addition, the outer decorative body 14 is also assembled.
The first edge 11 of the door sheet 6 is sandwiched between the inner surface 17 of the door sheet 6 and the rib 18, and the second edge 12 of the door sheet 6 is sandwiched between the outer surface 20 of the inner body 15 and the holding portion 21. It can be securely held only by being sandwiched, and the number of steps can be greatly reduced as compared with the conventional assembly in which the component parts are fitted together. On the other hand, the handle 5 composed of a single element does not rub against each other like a handle composed of a plurality of element parts, and it is possible to completely suppress the generation of unpleasant squeaking noise. Although the above embodiment is applied to the heat insulating door 2 of the refrigerator compartment of the refrigerator, it can be similarly applied to the heat insulating door of the freezing room, vegetable room and the like. As described above, according to the present invention, the recess extending vertically while maintaining the curved surface so as to enter the heat insulating wall into the door sheet, and the concave portion extending while maintaining the sheet surface of the door sheet flush. A first edge and a second edge extending vertically following the curved surface of the recess, and a sickle-shaped through hole is formed along the curved surface of the recess, and a single element is formed in the through hole. Since the handle is held across the first edge and the second edge, the handle made of a single element can be manufactured extremely inexpensively, and there is no need to fit element parts during assembly. Man-hours can be greatly reduced. Further, the present invention sandwiches the first edge of the door sheet between the inner surface of the outer decoration of the handle and the rib, and the second edge of the door sheet between the outer surface of the inner body and the holding portion. , So that the handle can be held securely.
