Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a frame for a refrigerator-freezer.

(Problems to be Solved by the Related Art and Invention) This freezer-refrigerated stocker is used, for example, in the sale of ice cream, and is roughly divided into a stocker body and
It comprises a decorative frame provided on the outer periphery of the upper end of the stocker body, and a pair of left and right slide type glass doors for opening and closing the opening of the stocker body.

And the makeup | decoration frame of the conventional freezer-refrigerator stocker is comprised as follows.

The frame member is composed of two pairs of frame members facing each other. On the back side of each frame member, a tubular portion is formed along the frame member. Screw holes are provided in the lower surface of the tubular portion near both ends. Then, adjacent frame members are connected by an L-shaped connecting plate having screw holes at both ends. That is, by inserting the screw inserted into each screw hole of the connecting plate into the screw hole of each frame member,
The above connection is possible.

In the case of the above decorative frame, it is necessary to provide a screw hole in each frame member, but normally when it is necessary to form a concave portion or a convex portion in the middle of a certain member as described above, it is necessary to form the member. Since the method of extrusion molding cannot be adopted, the method of injection molding had to be adopted.

The above-mentioned decorative frame of the freezer-freezer stocker is no exception, and the molding of each frame member was performed by injection molding.

However, in injection molding, there is a problem that the manufacturing cost of the mold used for this is very high. Further, if the design or size of the decorative frame is changed after the mold is made, the mold before the change cannot be used, and it is necessary to make a mold suitable for it.

In addition, inside the stocker body consisting of double walls inside and outside,
For example, a heat insulating material such as a urethane resin foam is filled, but the decorative frame provided on the outer periphery of the upper end of the stocker body has only screw holes on the lower surface of the tubular portion, so the stocker is It was difficult for the heat insulating material filled inside the main body to enter the tubular portion.

(Means for Solving the Problems) Therefore, in order to solve the various problems described above, the following means were taken.

That is, the makeup frame of the refrigerating stocker according to claim 1 is a makeup frame provided on the outer periphery of the upper end portion of the refrigerating stocker body having an opening for loading and unloading products on the upper surface,
The decorative frame is composed of two pairs of frame members facing each other and a plate-like connecting member that connects adjacent frame members at right angles at their ends, and one set of frame members is formed by extrusion molding. The other set of frame members is molded by injection molding, and each set of extrusion-molded frame members has a tubular portion extending in the longitudinal direction formed integrally with the frame member on the back side thereof. A long groove extending along the tubular portion is provided on the lower surface of the tubular portion, and a pair of injection-molded frame members are provided with fixing portions near both ends on the back side of the frame member. The part is fixed to the fixed part of the injection-molded frame member, and the other end is fixed to the long groove of the extruded frame member.

The decorative frame of the freezer-refrigerating stocker according to claim 2 is a decorative frame provided on an outer periphery of an upper end portion of a stocker main body in a freezer-refrigerating stocker having an opening for loading and unloading products on an upper surface, and the decorative frames face each other. One set of frame members formed of two pairs of frame members, one set of frame members formed by extrusion molding, the other one set of frame members formed by injection molding, and one set of frame members formed by extrusion molding, On the back side, a tubular portion extending in the longitudinal direction is formed integrally with the frame member, and the tubular portion is provided with a long groove extending along the tubular portion. , A connecting portion projecting outward from the vicinity of the end portion on the back side is integrally formed with the frame member, and a fixing portion is provided at the end portion of the connecting portion. Inject molded frame member and press fit It is made by connecting at right angles at its end and is shaped frame member.

(Operation) The decorative frame of the refrigerating stocker according to claim 1 is provided with a long groove into which a screw or the like is inserted in a frame member constituting the decorative frame. Unlike the screw hole provided in the middle of the frame member, this long groove extends in the longitudinal direction of the frame member. Therefore, regarding the frame member provided with this long groove,
Since extrusion molding is possible, molding can be performed at low cost.

One end of both ends of the plate-like connecting member is fixed to a fixed portion of the injection-molded frame member and the other end of the long groove of the extrusion-molded frame member. As a result, adjacent frame members formed by extrusion molding and injection molded frame members can be connected at right angles at their ends.

The decorative frame of the freezer-freezer stocker of claim 2 is different from that of claim 1 in that the connecting portion is integrally formed with the frame member. Therefore, the point that the frame member having the long groove can be extruded is similar to the above.

Even in this case, the connecting portion projects from the injection-molded frame member, and the fixing portion is provided at the end of the connecting portion. Then, the fixing portion and the long groove are combined to fix them. As a result, the frame members formed by the adjacent extrusion molding and the frame members formed by injection molding can be connected at right angles at their ends.

Further, since the decorative frame of claims 1 and 2 is provided with a long groove extending in the longitudinal direction on the back side unlike the conventional screw hole, the heat insulating material filled in the interior of the stocker body is used as the decorative frame.
