Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a strut structure in an insulated storage such as a refrigerator.

(Prior art) One type of insulated storage such as a refrigerator includes an insulated box having an opening on the front, and a frame with a rectangular cross section filled with insulating material. a support that is assembled in one of the states and divides the opening into a plurality of parts; There is an insulated warehouse equipped with a plurality of doors that close each part of the refrigerator.

In this type of heat-insulated storage, as shown in Figure 7 of Japanese Utility Model Application Publication No. 62-55073, the frame of the support column has both front and rear plates, and these plates are connected to each other at each side. A pair of left and right lateral plates,
and a pair of left and right outer plates that are assembled on the outside of each side plate and form a longitudinal space through which a lead wire is passed through the outside of the side plate. In addition, as another example, as shown in FIG. 3 of the same publication, the frame of the support column has a front plate and an opening to which the front plate is assembled on the front surface, and a lead wire on the inside of the rear surface. It is constituted by a frame portion having a U-shaped cross section and integrally formed with a longitudinal cylindrical portion through which the cylindrical portion is inserted.

(Problem to be solved by the invention) By the way, in the above-mentioned former column, there are many constituent members of the frame, so it is disadvantageous in terms of cost.
In addition, since each side plate is screwed to the front plate, assembly workability is poor. Furthermore, since a longitudinal space is formed between the side plates and the outer plate due to the structure of the frame, extending into and out of the heat-insulating storage, convection occurs in the space, reducing the heat-insulating effect. Furthermore, such support columns are widened on both sides by the width of both outer plates, thereby narrowing the opening area of the opening, thereby unequally restricting the size of items to be stored in the heat-insulating storage.

On the other hand, in the above-mentioned latter support body, since the U-shaped frame portion is a resin molded product, a special mold is required for molding the frame portion. Therefore, even if the dimensions of the support column are slightly changed in response to a slight change in the opening of the insulation, a new mold specifically for the frame must be made to accommodate this change, which reduces costs. This becomes a big problem. In addition, if this is to be addressed by changing the dimensions of the heat insulating box, the dimensions of a large component will have to be changed, which also poses a major problem in terms of cost.

Therefore, an object of the present invention is to solve all of the above-mentioned problems with both support columns.

(Means for Solving the Problems) The present invention is based on the above-described type of insulated storage, in which the frame of the support column has a front plate having side pieces at both ends that protrude a predetermined length backward; It consists of a rear plate that has side pieces at both ends, and a pair of side plates that are located on the outside of each side piece of these plates and connect the plates to each other. and a locking piece that is inserted between each side piece of both plates and is locked inside each side piece, and forms a longitudinal space with one of these side pieces. It is characterized by

(Operations and effects of the invention) In the strut body having such a structure, since the frame body is constituted by both front and rear plates and both side plates, the number of constituent members of the frame body is small and it is advantageous in terms of cost. Since they are locked and connected to each other, assembly workability is good. Also,
Due to the structure of the frame, no structural members are assembled on the outside of each side plate, and there is no space extending into and out of the insulation cabinet on the outside of the frame. The heat insulating effect will not deteriorate due to the heat insulating storage, and the support body will not become wide and the opening of the insulation storage will not be narrowed and the size of the items stored in the storage will not be unequally restricted. Moreover,
Since the front and rear plates constituting the frame are simply plates with side pieces extending forward for a predetermined length at both ends, the metal plates can be easily formed by press molding, and their widthwise width can be easily formed. Dimensions can also be changed easily and inexpensively.

(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings. FIG. 1 shows a refrigerator which is an example of a heat-insulating storage using the strut body according to the present invention. The refrigerator includes a heat insulating box 10, three pillars 20a, 2
0b, 20c and four doors 31, 32, 33,
It is equipped with 34.

The heat insulating box 10 is made by joining an inner box body 11 and an outer box body 12. A heat insulating material (not shown) is filled between these two box bodies 11 and 12, and an opening 1 is formed on the front surface.
It has 3. Each of the pillar bodies 20a to 20c is arranged in this opening 13, and the first pillar body 20a
are arranged vertically in the left and right center of the opening 13, and their upper and lower ends are attached to the upper and lower edges of the opening 13, and the second support 20b is attached to the opening 1
The left edge of the opening 13 and the first support 2 are arranged horizontally in the upper and lower center of 3, and the left edge of the opening 13 and the first support 2
It is assembled on the right side of 0a, and the third
The strut body 20c is similarly arranged, and its left and right ends are attached to the left side of the first strut body 20a and the right edge of the opening 13. As a result, each of the support columns 20a to 20c connects the opening 13 to the first opening portion 1.
It is divided into four parts: 3a to 4th opening part 13d. On the other hand, base end portions of four doors 31 to 34 are rotatably attached to the left and right edges of the opening 13. The first door 31 to the fourth door 34 face the first opening part 13a to the fourth opening part 13d,
Band-shaped gaskets 31a~ on their inner peripheral edges
34a is fixed, and their rotating ends are brought into contact with each of the support columns 20a to 20c and each edge of the opening 13, thereby independently sealing each opening portion 13a to 13d.

As shown in FIG. 2, the first support column 20a includes a frame body consisting of a front plate 21, a rear plate 22, and a pair of left and right side plates 23, 24, and a heat insulating material 25 filled in this frame body. It is made up of.

The front plate 21 includes a front plate portion 21a and a pair of left and right side pieces 21b extending rearward from both ends of the front plate portion 21a.
and an inward flange portion 21c extending inward from the rear end of each side piece 21b, and each of these portions 21a
21c are integrally formed by press-molding a metal plate. Rear plate 22
consists of a rear plate portion 22a and a pair of left and right side pieces 22b extending forward from both ends of the rear plate portion 22a, and these portions 22a, 22b are integrally formed by press molding a metal plate. Each side plate 23, 24 is a side plate portion 23
a, 24a, protruding pieces 23b, 24b protruding inward from the middle of the inner sides thereof, and first locking pieces 23c, 24 extending forward from the tips of the protruding pieces 23b, 24b.
c. It consists of second locking pieces 23d and 24d extending rearward, and each of these parts is integrally formed of synthetic resin.

Each of these members 21 to 24 is assembled in the state shown in FIG. A foaming agent is injected and the mixture is foamed. The heat insulating material 25 formed by this foam presses each member 21 to 24 outward, and both plates 21 and 22
3 and 24 and are joined to each other, thereby forming the support column 20a. The pillar body 2
In 0a, a cross section extending in the longitudinal direction is formed by each inward flange portion 21c of the front plate 21 and the first locking pieces 23c, 24c and protrusions 23c, 24b of each side plate 23, 24 that lock thereto. Square spaces 26a and 26b are formed. Lead wires 36a and 36b for anti-dew heaters 35a and 35b are inserted into these spaces 26a and 26b. In addition, each dew-proof heater 35a, 35b
Before forming the frame, the front plate 21 is
It is attached to the inner surface of the housing via a tape 37 or the like.
The support column 20a has fixing fittings 14 attached to the upper and lower edges of the opening 13 of the insulation box 10 at both upper and lower ends thereof.
a, it is fixed with screws 14b.

The second strut body 20b and the third strut body 20c are also configured to have the same cross-sectional shape and structure as the first strut body 20a, and each end of the second strut body 20b has the same fixing means as the first strut body 20a. Similarly, each end of the third column 20c is fixed to the left edge of the opening 13 and the rear plate 22 of the first column 20a at the rear plate 22 of the first column 20a and the right side of the opening 13. Fixed to the edge.

In the first support column 20a having such a structure, since the frame body is constituted by both the front and rear plates 21, 22 and both side plates 23, 24, the number of constituent members of the frame body is small, which is advantageous in terms of cost. 21 to 24 are respective locking pieces 23c, 23d, 2
Since the parts 4c and 24d are simply locked and connected to each other, there is no need for assembling work such as screw fixing as in the conventional art, and the assembling workability is good.

In addition, in the first support column 20a, since there is no space extending inside and outside the heat insulating storage, there is no reduction in the heat insulation effect due to the space, and
Since there are no structural members of the struts on the outside of each side plate 23, 24, the struts are wide, narrowing the opening of the heat-insulating compartment and making it impossible to store items of different sizes inside the refrigerator. There are no restrictions.

Furthermore, since the front and rear plates 21 and 22 constituting the frame of the support column 20a have a shape that can be easily formed by press-forming metal plates, changing the dimensions of these in the width direction can be done easily and inexpensively. I can do it. Therefore, the dimension of the support column 20a in the width direction can be easily and inexpensively changed.

In addition, since the second and third support bodies 20b and 20c are configured similarly to the first support body 20a,
It has the same effect as the first support column 20a.
