DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window frame structure in, for example, a clean room or a prefabricated refrigerator / refrigerator.

[0002]

2. Description of the Related Art Conventionally, clean rooms and prefabricated refrigeration
2. Description of the Related Art In refrigerators and the like, a window is formed by inserting glass into an opening provided in an opening / closing panel and the like, and the inventory status of stored items and the like in a refrigerator can be seen from the outside through the window. .

[0003] As an example of this window frame structure, for example, those configured as shown in FIGS. 9, 11 and 12 are known.

In the window frame structure shown in FIG. 9, a wooden frame c is used for a window frame b of a panel a, and a fitting step d shown in FIG. Window body f
Is inserted from the indoor side via a packing g, and a gap between the two is filled with a caulking material h. Then, an aluminum shape member j is applied to the surface of the surface plate i of the panel to set a screw (wood screw) k
It is stopped by. The surface plate i of the panel a,
The space between i is filled with a heat insulating material 1 such as a urethane foam material.

In the window frame structure shown in FIG. 11, instead of providing a fitting step d in a wooden frame c, an aluminum L-shaped member m is applied to the surface of a surface plate i of the panel and stopped by a screw k.
A window f arranged in a window frame b by both L-shaped members m, m
It is a structure of sandwiching. It is to be noted that a structure in which the window body f is sandwiched between the end faces of the panel without using the wooden frame c is also employed.

[0006] The window frame structure of FIG.
A window member f is sandwiched by a cover member n having an approximately L-shaped cross section formed of an aluminum shape member, and a vinyl chloride shape member o is disposed on a window frame b of a panel a. Then, the skirt p of the cover member n is riveted (blind rivet) q
And a decorative plate r for hiding the head of the rivet q is provided on the skirt portion p. As shown in FIG. 13, the window corners, which are the joints between the sides of the cover member n, have the L-shaped connection grooves s of the cover member n after butting the surfaces of the sides of the cover member n. The connection is performed by fitting the connecting member t having a cross section. Here, u is a heater for preventing dew condensation.

[0007]

However, the conventional window frame structure has the following disadvantages.

In the case of the window frame structure shown in FIGS. 9 and 10, since the frame material provided on the panel end face is made of wood, it is difficult to always prepare a wooden frame c having a desired shape and dimensions.
In particular, in the case of the wooden frame c provided with the fitting step portion d as in the case of FIG. 9, since the processing requires time and effort, the period from ordering to delivery tends to be longer. In addition, skill is required to accurately obtain dimensions that match the window frame on site, and the dimensional accuracy is not very good when compared with vinyl chloride products and the like. Further, when the thickness dimension of the panel is changed, there is a problem that it is not easy to make a corresponding change and the response is slow. There is also concern about the corrosion of wooden frames due to aging.

In the conventional window frame structure shown in FIG. 11, the window frame b is similarly constituted by the wooden frame c, so that it has the same disadvantages as described above, and further has the following disadvantages. That is, a panel a is composed of a wooden frame c, a urethane foam l, and a pair of surface plates i, i in a factory, and L-shaped members m, m are fixed on both sides of the window frame b with screws k. Therefore, it is not easy to respond to a change or correction in accordance with the on-site dimensions, for example, when it is desired to shift the position of the window f in the thickness direction of the panel a. In addition, since the head of the screw k is exposed, the aesthetic appearance is impaired, and the screw k may fall off.
Furthermore, there is a problem that it takes a relatively long time to assemble, a delivery time is easily delayed as compared with a normal panel, and the cost is high.

In the conventional window frame structure shown in FIGS. 12 and 13, compared to the above-described structures shown in FIGS.
Although there is an advantage that the panel can be cut and mounted on site, there is a problem that the strength of the contact portion between the panel end face and the glass e is insufficient.

Therefore, an object of the present invention is to solve the above-mentioned problems, to provide a window frame structure which is easy to mount a window body including glass, can easily cope with changes and modifications, and is excellent in aesthetic appearance. To provide.

Since the cover member is divided into two parts, even if the thickness of the panel is changed to, for example, a large one, the interval between the pair of cover members is increased, and the amount of packing and caulking material is increased. By doing so, it is possible to deal with it.

Further, since the decorative edge is also divided into two parts, even when the thickness of the window body is changed to a large one, the amount of the packing and the caulking material is reduced, or the amount of protrusion of the holding portion is reduced. It can be easily dealt with by replacing it with a smaller one. In this case, the cover member may be a common one, and it is not necessary to prepare a cover member of any different size, and the decorative edge may be simply inserted.

Further, since the decorative edge has a function of covering the outside of the cover member and a function of sandwiching the window body, it is not necessary to prepare members having independent functions.

(2) In the window frame structure according to the second aspect, the window frame structure according to the first aspect is continuous with the inner wall surface of the holding groove of the cover member in the depth direction of the groove. An uneven strip is formed, and an uneven strip engaging with the uneven strip is formed on the outer peripheral surface of the convex strip of the decorative edge. By the engagement of the two concave and convex strips, the decorative edge can be more completely fixed to the cover member.

(3) In the window frame structure according to the third aspect, a cover member having a substantially U-shaped cross section for covering an opening-side end surface of a panel constituting a window mounting opening, and covering the outside of the cover member, The cover member and the decorative edge are fixed to the panel with a fixing member.

Since the decorative edge is divided into two parts, even if the thickness of the window body is changed to a large one, the amount of the packing and the caulking material is reduced, or the amount of protrusion of the holding portion is small. It can be easily dealt with by exchanging them.
