By the way, as described above, when the end portions of the vertical and horizontal frame members are inclined at approximately 45 °, if the inclined portions of the vertical and horizontal frame members are not precisely processed, the ends of both frame members There is a problem that a gap is generated between the parts. Further, when assembling the glass door, if the vertical and horizontal frame members are not held by a jig, there is a gap between the vertical frame member and the horizontal frame member (that is, between the inclined portions). As a result, there is a drawback that the assembly work becomes complicated. And when a gap occurs in the abutting portion of the vertical and horizontal frame members, in particular, the outside of the warehouse, the appearance deteriorates, and water drops, dust and the like enter the inside of each frame member from the gap to maintain a sanitary state. Will lead to difficult problems.
Then, an object of this invention is to provide the door structure of the storage which can prevent that a clearance gap produces between the butt | matching edge parts of the warehouse outer side in each frame member.

In order to overcome the above-mentioned problems and achieve the intended purpose, the storage door structure according to the present invention includes:
A vertical frame member that is attached to an edge extending in the vertical direction of a rectangular transparent plate, and a first frame that is formed at both ends of the vertical frame member and that inclines toward the other end toward the transparent plate. An inclined portion, a horizontal frame member attached to an edge extending in the left-right direction of the transparent plate, and a second frame formed at both end portions of the horizontal frame member and inclined toward the other end side toward the transparent plate. And a connecting member having a first connecting part inserted and fixed from an end of the vertical frame member and a second connecting part inserted and fixed from an end of the horizontal frame member, When both frame members are fixed to the connecting member, the first inclined portion of the vertical frame member and the second inclined portion of the horizontal frame member abut each other.
The first and second connecting portions are opposed to an outer surface facing the outer wall portion facing the edge of the transparent plate in each of the vertical and horizontal frame members, and a rear side wall portion facing the inner side of each frame member. Each is formed in a substantially U-shaped cross section from the rear side and the front side facing the front side wall facing the outer side of each frame member,
Forming at least one of a rear side surface and a front side surface in the first and second connecting portions so as to be inclined from the outer side to the inner side as going from the outer side surface to the transparent plate;
Only the side surface is inclined from the refrigerator outside the compartment inner side of the first and second connecting portions, by fixing the respective side walls corresponding in the vertical and horizontal frame member, the first and the said longitudinal lateral frame members Inclining from the outer side of the warehouse along the second connecting portion to the inner side of the warehouse, the first inclined portion and the second inclined portion are in close contact with each other, and
When the first and second connecting parts are inserted into the vertical and horizontal frame members, the frame members are moved from the outside of the box to the inside of the box between the outer wall of each frame member and the outer surface of each of the connecting parts. A gap that allows tilting is formed .

According to the door structure of the storage according to claim 1 of the present invention, at least one of the outer surface and the inner surface of the first and second connecting portions of the connecting member fixed to the vertical and horizontal frame members is transparent. When the first and second connecting parts and the vertical and horizontal frame members are fixed by being formed so as to incline from the outer side to the inner side as they go to the plate, each frame member moves along the inclination of the connecting part. From the inside to the inside. That is, it is possible to prevent the first and second inclined portions in each frame member from approaching each other and the inclined portions to closely contact each other to form a gap. Therefore, the appearance can be improved and a good hygiene state can be maintained.
Further, when the first and second connecting portions are inserted into the vertical and horizontal frame members, a gap is formed between the outer wall portion of each frame member and the outer surface of each connecting portion. When the frame member is displaced, the outer surface of each connecting portion does not come into contact with the outer wall portion of each frame member and does not hinder the displacement of the frame member.

The glass door 16 is pivotally supported so as to open and close the opening of the housing 12 via a hinge mechanism (not shown) provided on the right side of the glass door 16.

  As shown in FIG. 3, FIG. 5 or FIG. 6, each of the vertical frame member 20 and the horizontal frame member 22 is formed in a hollow, substantially rectangular cylindrical shape in which a hollow portion 24 extends along the longitudinal direction thereof. In addition, a groove 26a extending along the longitudinal direction is formed on the inner wall 26 facing the glass plate 18 in each of the frame members 20 and 22. And each frame member 20 and 22 is attached to the edge of the glass plate 18 by fitting the corresponding edge of the said glass plate 18 in the said groove part 26a. Further, in the longitudinal direction of each frame member 20, 22 on the side of the hollow portion 24 in the front side wall portion 28 located on the outer side of the vertical frame member 20 and the horizontal frame member 22 and the rear side wall portion 30 located on the inner side of the warehouse. Protruding pieces 28a and 30a extending along the projecting portions 28a and 30a are provided so that the connecting member 41 can be inserted between the projecting pieces 28a and 30a and the outer wall portions 32 of the frame members 20 and 22. It is configured.

  Further, at both ends in the longitudinal direction of the vertical frame member 20, first inclined portions 36, 36 that are inclined toward the other end portion side from the outer wall portion 32 toward the inner wall portion 26 are formed, Similarly, second inclined portions 37, 37 that are inclined toward the other end portion from the outer wall portion 32 toward the inner wall portion 26 are formed at both ends in the longitudinal direction of the horizontal frame member 22. The first and second inclined portions 36 and 37 are set so that an angle formed with the outer wall portion 32 is approximately 45 °, and the first inclined portion 36 of the adjacent vertical frame member 20 and the horizontal frame member 22 are adjacent to each other. By abutting (abutting) the second inclined portion 37, both the frame members 20 and 22 are substantially orthogonal to each other. That is, when the vertical frame members 20 and the horizontal frame members 22 are assembled, the rectangular frame shape is formed. In addition, in the vicinity of both end portions of the rear side wall portion 30 in each of the vertical and horizontal frame members 20 and 22, through holes 30b and 30b penetrating the hollow portion 24 are formed at two positions spaced apart in the longitudinal direction. (See Figure 2). Note that the vertical frame member 20 attached to the left edge of the glass plate 18 is provided with a substantially L-shaped gripping portion 38 on the front side wall portion 28, and the glass is formed by placing a finger on the gripping portion 38. The door 16 can be opened and closed.

  As shown in FIG. 4, the connecting member 41 is inserted into the hollow portion 24 of the vertical frame member 20, and the first connecting portion 43 connected to the vertical frame member 20 and the hollow of the horizontal frame member 22. The second connecting portion 45 inserted into the portion 24 and connected to the horizontal frame member 22 is formed in a substantially L shape. In addition, in the Example, the said 1st connection part 43 and the 2nd connection part 45 are formed in the same shape, and all the connection members 41 arrange | positioned at the four corners of the said glass door 16 use a common member. It has been. As shown in FIG. 4B, each of the first and second connecting portions 43, 45 includes an outer surface 47 facing the outer wall portion 32 of each of the vertical and horizontal frame members 20, 22, and each frame member. The rear side surface 49 facing the rear side wall portion 30 of the 20, 20 and the front side surface 51 facing the front side wall portion 28 of each frame member 20, 22 are formed in a substantially U-shaped cross section. The rear side surface 49 of the first and second connecting portions 43 and 45 has screw holes 49a at positions aligned with the through holes 30b and 30b formed in the vertical and horizontal frame members 20 and 22 in the front-rear direction. 49a are screwed, and the first and second connecting portions 43, 45 are inserted into the hollow portions 24 of the frame members 20, 22, respectively, and inserted into the through holes 30b from the rear side wall portion 30 side. The connecting member 41 is fixed to the frame members 20 and 22 by screwing the screw (fixing means) 55 into the screw hole 49a.

The front and rear side surfaces 49, 51 of the first and second connecting portions 43, 45 are from the outer side to the inner side as they go from the outer side surface 47 to the end edges (glass plates 18) of the side surfaces 49, 51. It is formed so as to be inclined. That is, as shown in FIG. 4B, the inner angle angle θ ₁ formed by the outer side surface 47 and the rear side surface 49 is set to satisfy θ ₁ > 90 °, and the outer side surface 47 and the front side surface 51 inner angle theta ₂ formed of, is set to be θ ₂ ≦ 90 °. In addition, although the 1st connection part 43 was shown in FIG.4 (b), the 2nd connection part 45 is formed similarly. Thus, by forming the rear side surface 49 and the front side surface 51 so as to be inclined, when the vertical and horizontal frame members 20 and 22 and the connecting member 41 are fixed by screws, the frame members 20 and 22 The front side wall portion 28 is attached with the edge on the glass plate 18 side retracted to the inner side (see FIG. 3).

The angle θ ₁ formed by the outer side surface 47 and the rear side surface 49 is preferably set in a range of 92 ° ≦ θ ₁ ≦ 93 °. That is, when the angle θ ₁ formed by the outer side surface 47 and the rear side surface 49 is set in a range of θ ₁ > 93 °, the glass plate 18 in the front side wall portion 28 of each of the vertical and horizontal frame members 20 and 22 is set. This is because the glass plate 18 fitted in the groove portion 26a is excessively burdened with the side edge being attached in a state of being retracted to the inside of the warehouse too much. On the other hand, the angle θ ₂ formed by the outer side surface 47 and the front side surface 51 is such that the front and rear side walls of the vertical and horizontal frame members 20 and 22 are fixed when the vertical and horizontal frame members 20 and 22 and the connecting member 41 are fixed by screws. What is necessary is just to set so that the part 28 and the front side surface 51 of the connection member 41 may not interfere. Specifically, the angle θ ₂ formed by the outer side surface 47 and the front side surface 51 is preferably set in a range of 89 ° ≦ θ ₂ ≦ 90 °. In addition, the first and second connecting portions 43, 45 have a length dimension from the outer side surface 47 to the edge of the rear side surface 49, and projecting pieces from the outer wall portions 32 in the vertical and horizontal frame members 20, 22. It is set to be shorter than the separation dimension up to 28a and 30a. That is, when the first and second connecting portions 43 and 45 are inserted into the hollow portions 24 of the frame members 20 and 22, between the outer wall portion 32 and the outer surface 47, and the protruding piece 30a. A gap 34 is formed between the rear edge 49 and the edge of the rear side surface 49 (see FIG. 5A or FIG. 6A).

(Effects of Example)
Next, the operation of the storage door structure according to the embodiment will be described. First, a method for assembling the glass door 16 of the showcase 10 according to the embodiment will be described. The first connecting portion 43 of the connecting member 41 is inserted into the hollow portion 24 from the upper and lower ends of one of the vertical frame members 20 (see FIG. 5A), and is inserted into the rear side wall portion 30 of the vertical frame member 20. Screws 55 are inserted into the drilled through holes 30b, and the screws 55 are screwed into the corresponding screw holes 49a of the first connecting portions 43, thereby fixing the connecting members 41 to both ends of the vertical frame member 20. To do. And the 2nd connection part 45 of each connection member 41 fixed to the said vertical frame member 20 is each inserted in the hollow part 24 of the said horizontal frame member 22 (refer Fig.6 (a)), and the back of the horizontal frame member 22 is carried out. A screw 55 is inserted into each through hole 30b formed in the side wall portion 30 and the screw 55 is screwed into a corresponding screw hole 49a of each second connecting portion 45, whereby the horizontal frame member 22 is connected to the connecting member 41. Secure to. In this state, the upper and lower edges of the glass plate 18 are inserted into the grooves 26a and 26a of the horizontal frame members 22 and 22 positioned above and below, and the left or right edge of the glass plate 18 is connected to the vertical frame member 20. It fits into the groove 26a.

  Further, the first connecting portion 43 of the connecting member 41 is inserted into the hollow portion 24 from the upper and lower ends of the remaining vertical frame member 20, and each through hole 30 b formed in the rear side wall portion 30 of the vertical frame member 20. Then, the screws 55 are inserted into the corresponding screw holes 49a of the first connecting portions 43, and the connecting members 41 are fixed to both ends of the vertical frame member 20, respectively. Further, the second connecting portions 45 of the connecting members 41 fixed to the vertical frame member 20 are inserted into the hollow portions 24 and 24 of the horizontal frame members 22 and 22 to which the glass plate 18 is attached. Then, the screw 55 is inserted into each through hole 30b formed in the rear side wall portion 30 of each horizontal frame member 22, and the screw 55 is screwed into the corresponding screw hole 49a of each second connecting portion 45. Thus, each horizontal frame member 22 and the connecting member 41 are fixed, and the glass door 16 is assembled.

  Here, the 1st and 2nd connection parts 43 and 45 of the said connection member 41 in an Example are inclined so that it may incline from the warehouse outer side to the warehouse inner side as it goes to the edge part of the front and back side surfaces 49 and 51 from the outer surface 47. It is formed. Therefore, when the screws 55 are screwed into the screw holes 49a of the first and second connecting portions 43 and 45, the rear side wall portions 30 of the frame members 20 and 22 correspond to the corresponding connecting portions 43 and 45, respectively. The frame members 20 and 22 are displaced so as to contact the rear side surface 49 (see FIG. 5B or FIG. 6B). That is, the first inclined portion 36 of the vertical frame member 20 and the second inclined portion of the horizontal frame member 22 are moved by moving the front side wall portions 28 of the vertical frame member 20 and the horizontal frame member 22 in a direction close to each other. It can prevent that the part 37 collides closely and a clearance gap arises between them. Accordingly, water or dust does not enter the inside of each frame member from between the first inclined portion 36 of the vertical frame member 20 and the second inclined portion 37 of the horizontal frame member 22 as in the prior art. The glass door 16 can be kept clean.

  Further, since no gap is generated between the butted end portions of the vertical and horizontal frame members 20 and 22 located outside the warehouse, that is, the first and second inclined portions 36 and 37, the appearance is not impaired. When the first and second connecting portions 43 and 45 are inserted into the hollow portions 24 of the vertical and horizontal frame members 20 and 22, the outer wall portions 32 and the connecting portions 43 and 45 of the frame members 20 and 22 are inserted. A gap 34 is formed between the outer side surface 47 and the outer side surface 47. Accordingly, when the rear side wall portion 30 of each frame member 20, 22 is displaced so as to contact the rear side surface 49 of the corresponding connection portion 43, 45, the outer side surface 47 of each connection portion 45 is moved to the frame member 20, 22. The displacement of the frame members 20 and 22 is not hindered by coming into contact with the outer wall portion 32.

  Further, in the conventional glass door 16, when the vertical frame member 20 and the horizontal frame member 22 are assembled, the butted end portions of the vertical frame member 20 and the horizontal frame member 22 (the first of the frame members 20, 22). And it is necessary to hold with a jig or the like so that no gap is generated between the second inclined portions 36 and 37. On the other hand, in the glass door 16 of the embodiment, the connecting member 41 and the frame members 20 and 22 are assembled as described above, so that the butted end portions of the frame members 20 and 22 (the frame members 20 and 22, respectively). 22), it is not necessary to use a jig or the like for holding the frame members 20 and 22. For this reason, there exists an advantage which can simplify the assembly | attachment operation | work of the glass door 16 and can perform an operation | work in a short time. Further, it is not necessary to increase the processing accuracy of the first and second inclined portions 36, 37 of the vertical and horizontal frame members 20, 22, and the cost can be reduced.

[Example of change]
The storage door structure according to the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the embodiment, the front and rear side surfaces of the connecting member are formed so as to incline from the outer side toward the inner side toward the edge of the front and rear side surfaces from the outer side surface. What is necessary is just to form so that it may incline from the outer side to the inner side. That is, the shape of the connecting member can be arbitrarily determined if it is formed so that the inner edge of the frame member can be retracted to the inner side when the vertical and horizontal frame members are connected and fixed. In addition, in the Example, although the door provided with the structure concerning the present invention was adopted as the glass door of the showcase, it is not limited to this, and a frame member is provided on the outer peripheral edge of the transparent plate such as a refrigerator or a freezer. It can be suitably employed for a storage door configured to be attached.
