BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel frame fixing structure for connecting and fixing an outer surface plate and an inner surface plate to form a heat insulating box in a fresh food storage.

[0002]

2. Description of the Related Art As a structure of a panel frame for making a conventional heat insulating box, a heat insulating material is filled between an outer box and an inner box,
In the one formed by inserting the bent flange of the back plate of the outer box into the flange of the side plate, a cut-raised protrusion is formed on the bent flange, and the cut-raised protrusion is formed on the folded flange. A structure in which it is engaged with an engagement hole has been devised and is known (Japanese Utility Model No. 02-96591).

[0003]

However, in such a conventional structure, there is the following problem in the engagement between the engagement hole and the cut and raised protrusion. Since it is necessary to provide an engaging hole in the back plate in accordance with the cutting and raising of the side plate, it is difficult to position the hole. Further, in order to engage the cut-and-raised part with the engagement hole, it is necessary to perform processing such as bending so that a force is applied in a direction so that the protrusion does not come out of the hole. Further, a sealing material is required to close the hole so that the foaming agent does not overflow from the engaging hole. Moreover, since the side plate and the back plate are in contact with each other, when both are formed of a heat conductive material such as metal and the outer plate and the inner plate are connected and used, external heat will flow in. This will adversely affect cooling. Therefore, the present invention has been made in view of the above-mentioned drawbacks of the prior art, and does not require processing such as engaging holes and bending or sealing material, and very easily engages the back plate and the side plate while performing the function of heat cutting. It is to provide a panel structure that can be combined.

[0004]

[Means for Solving the Problems] That is, the present invention provides a panel frame made of synthetic resin in which two-sided holding portions each of which has an upper holding piece and a lower holding piece open to the outside on both sides are formed, and the panel. It is made up of a plate material inserted into the two-pronged holding part of the frame, and a projection is continuously provided at a predetermined distance D from the back toward the upper holding part inside the lower holding part which constitutes the holding part of the panel frame, This object is achieved by a panel frame fixing structure in a fresh food storage in which a plurality of bag-shaped cut-and-raised parts which are raised toward the center of the plate material at a predetermined distance d from the peripheral edge of the plate material are provided. Further, the invention of claim 2 is such that a central protrusion extending in the longitudinal direction is continuously provided at the central portion of the panel frame.

[0005]

In the device according to the present invention, the bag-shaped cut-and-raised side of the plate material such as the outer surface plate and the inner surface plate is inserted into the bifurcated holding portion of the panel frame at predetermined intervals. As a result, when the plate material is inserted, the slanted surface of the bag-shaped cut-and-raised part comes into contact with the projections provided continuously on the lower holding piece, so that the plate material can be smoothly inserted into the back. After inserting to the predetermined distance d, the protrusion provided inside the bifurcated holding part and the raised portion of the bag-shaped cut-and-raised part of the plate material come into contact with each other, and the movement to remove the plate material is resisted. Therefore, the panel frame and the plate material are firmly fixed. Further, the side plate and the back plate are communicated with each other through the panel frame, and when the panel frame is made of synthetic resin or the like, it exhibits a heat cutting action. Further, in the case where the panel frame is provided with the protrusion in the center, the protrusion is in a state of protruding substantially perpendicularly to the wall surface of the storage chamber, and can function as a shelf receiving metal fitting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 shows a panel frame 1 according to the present invention.
In the present embodiment, the panel frame 1 has the bifurcated holding portions 3 and 4 symmetrically open to the outside through the plane that passes through the central protrusion 2 extending in the longitudinal direction to sandwich the plate materials 5 and 6. 1 and the lower side 3b, 4 of the holding pieces 3a, 3b, 4a, 4b which are integrally formed and constitute the holding portions 3, 4 in the embodiment of FIG.
b is formed in a taper shape so that the tip extends downward and the interval between the upper holding pieces 3a, 4a widens, and further, the inside of the lower holding pieces 3b, 4b faces the upper holding pieces 3a, 4a. Protruding projections 7 and 7 are provided at a predetermined distance D from the back of the holding portions 3 and 4, and the projections 7 and 7 are continuous in the longitudinal direction of the panel frame 1.

Next, as shown in FIGS. 2 and 3, the outer plate 5 is used.
And the inner surface plate 6 is cut up at a predetermined distance d (D≈d) in a direction opposite to the peripheral edge and pressed toward the peripheral edge to form an inclined surface (tapered shape). A plurality of bag-shaped cut-and-raised parts 8 are provided, and a plurality of the bag-shaped cut-and-raised parts 8 are provided at predetermined intervals in the longitudinal direction.

FIG. 4 is a partially transparent perspective view showing a state where the outer surface plate 5 and the inner surface plate 6 are engaged with each other by the panel frame 1, and the panel frame 1 covers the entire circumference on the inner wall side. At the corners, the ends (contact parts) are cut at an angle of 45 degrees so that no gap is created when the panel frames 1 and 1 contact each other (FIG. 5).

In the panel frame according to the embodiment of the present invention having the above-described structure, the plate-shaped members 5, 6 are provided with the bag-shaped cut-and-raised portions 8 at the peripheral ends thereof. To insert. Then, the plate member is guided by the tapered portions at the tips of the holding portions 3 and 4 into the holding portions 3 and 4, and the holding pieces 3h,
The protrusion 7 provided on 4b and the bag-shaped cut-and-raised part 8 are in contact with each other, but both the bag-shaped cut-and-raised part 8 and the protrusion 7 are held in a gentle taper shape in the direction in which the plate members 5 and 6 are inserted, so that they can be held. Piece 3b,
4b is pushed down and the plate members 5 and 6 are pushed further into the interior, and the cut-and-raised parts 8 are set between the projections 7 of the holding pieces 3b and 4b and the interior, and the plate members 5 and 6 are fixed. Therefore, when the board members 5 and 6 that have once entered are to be removed from the panel frame 1, the raised portions of the bag-shaped cut-and-raised part 8 and the projections 7 are engaged with each other and cannot be removed by normal force. Further, the central protrusion 2 is in a state of protruding substantially perpendicularly to the wall surface of the storage room serving as the storage section,
When the central protrusions 2 are arranged in parallel with the horizontal plane, they can function as shelf receiving metal fittings. Further, JP-A-63-
When applied to an indirect cooling type refrigerator as described in Japanese Patent No. 185359, it can also be used as a fixed frame for an inner box.

[0010]

As described above, the panel frame fixing structure according to the present invention has a structure in which bag-like cut-and-raised parts are provided at a predetermined distance from the peripheral edge of the plate material to be inserted and are inserted into the holding portion of the panel frame. Therefore, it is possible to provide the one that is easy to insert and difficult to pull out. Further, since the holding piece of the panel frame closes the hole without using a sealing material, a resealing material different from the conventional one is unnecessary. Since the panel frame 1 is made of synthetic resin, heat conduction between the outer surface plate and the inner surface plate can be blocked, and the heat cutting effect is high.
