For example, in FIG. 10, the pin device P is attached to the contact portion 56 of the frame member W3 as shown in FIG.
In, it is attached by abutting from below. An inclined portion 57 is continuously formed at both ends of the contact portion 56, and a heat insulating material flows into the inclined portion 57 as shown by an arrow a and foams. Is pressed in the direction. Since the hook passage opening 20 is formed in the abutting portion 56 of the frame member W3 as shown in FIG. 10C, the frame member W3 may be deformed. When the frame member W3 is deformed, the hook passage opening 20 becomes narrow, which prevents passage of the hook member 31.

On the other hand, in FIG. 11, the hook device F is attached to the abutting portion 41 of the frame member W2 by abutting from the lower side in FIG. 11 (b). An inclined portion 59 is continuously formed at both ends of the abutting portion 41, and the heat insulating material flows into the inclined portion 59 as shown in the arrow c and foams. Is pressed in the direction. And
Since the hook passing opening 45 is formed in the contact portion 41 of the frame member W2 as shown in FIG. 11C, the frame member W2 may be deformed. When the frame material W2 is deformed,
The hook passage opening 45 expands, causing leakage of the heat insulating material.

Further, in FIG. 12, when the heat insulating material is filled and foamed, the front wall 11 of the pin support case 1 of the pin device P is formed.
Also, pressure is applied to the rear wall 12, and the hook entry opening 4 of the pin support case 1 becomes narrower as shown by the broken line. As a result, the passage of the hook member 31 may be hindered or the heat insulating material may leak.

Then, in FIG. 12, the heat insulating panel 53
Although it is manufactured in a collapsed state, this heat insulation panel 53
Frame material W1 to which the pin device P is attached at the time of manufacturing
Are fitted into and supported by the end portions of the face material N. However, since the frame member W1 cannot stand on its own, the frame member W1 may come off the face member N and fall over as shown by the arrow.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a heat insulating panel capable of reducing deformation during filling and foaming of a heat insulating material. Further, it is a secondary object to provide a heat insulating panel in which the frame material to which the pin device is attached can be self-supporting at the time of manufacturing.

FIG. 4 is a front view of the hook device.

In the first embodiment shown in FIG. 2, the hook passing openings 63, 64, 67 formed in the frame members W4, W5 of the heat insulating panel are the same as the conventional hook passing openings 20, 45. Is different. In the conventional example, the lengths of the hook passage openings 20 and 45 of the frame members W1 and W2 in the longitudinal direction are the longitudinal lengths of the hook entry opening 4 of the pin device P or the hook protrusion opening 26 of the hook device F. It is formed to be substantially the same. On the other hand, in the first embodiment shown in FIG. 2, a connecting portion 61 for connecting both sides is formed at a portion of the abutting portion 18 of the frame member W4 that faces the pin 2, so that the conventional hook passing portion can be used. The opening 20 becomes two hook passage openings 63 and 64. The hook passage opening 64 is used when the second pin is inserted and fixed in the gas vent hole 14. By providing this second pin, it becomes possible to connect a prefabricated freezer and a prefabricated refrigerator having different thicknesses of the heat insulating panel with the same heat insulating panel.

On the other hand, the pin 2 of the pin device P and the hook device F
The shaft 28 of the rotor 27 has approximately the same height when the heat insulating panel 53 is placed upright, and the line connecting the pin 2 and the shaft 28 is shown by a chain line. The alternate long and short dash line is substantially perpendicular to the frame members W4 and W5. The connecting portion 66 is formed at the same height position as the alternate long and short dash line of the frame member W5. The connecting portion 66 faces the shaft 28 of the rotor 27 of the hook device F, and faces the pin 2 of the pin device P via the connecting portion 61 when the hook device F is connected to the pin device P. . Since the connecting portion 66 is formed, the conventional hook passage opening 45 is replaced with the hook passage opening 6.

By the way, the hook intrusion opening 4 of the pin device P and the hook protruding aperture 26 of the hook device F are used to remove the die during manufacturing and to remove the heat insulating material that has invaded the inside of the pin device P and the hook device F. In consideration of this, the hook member 31 is formed longer in the longitudinal direction than the rotation range for engaging the pin 2. Further, since the hook passage opening of the conventional frame member is formed in accordance with the hook entry opening 4 or the hook projecting opening 26, it is formed longer than the portion through which the hook member 31 passes.

However, as in this embodiment, the lengths of the hook passage openings are not adjusted to the hook entry openings 4 or the hook projection openings 26, and the connecting portions 61 and 66 are provided on the frame members W4 and W5. , Especially the contact portion 1 of the frame members W4, W5

On the other hand, the frame member W7 shown in (d) to which the hook device F is attached has a different opening arrangement from the frame member W5 of the first embodiment shown in (b). Since the hook member 31 does not pass through the opening 68 of the first embodiment, the opening 68 is not provided in the second embodiment. In addition, in (d), the portion corresponding to the opening 68 is hatched.

Further, the pin device P of the third embodiment will be described with reference to FIGS. FIG. 4 is a view for explaining the pin device, (a) is a plan view, (b) is a front view,
(C) is a side view. 5A and 5B are views for explaining a frame member to which the pin device is attached, FIG. 5A is a diagram of the frame member before the pin device is attached, and FIG. 5B is a diagram of a frame member different from FIG. . FIG. 6 is an explanatory diagram of a heat insulating panel in which the pin device and the frame member illustrated in FIG. 5A are assembled. FIG. 7 is a view for explaining the assembled state of the pin device, and (a)

The pin device P of the third embodiment is different from the conventional device shown in FIG. 10 in that elongated ribs 71 as projecting portions are formed so as to protrude on both sides of the flange 5 forming the surface on the frame material side. (Difference 1), a point that a protruding plate 75 having a different shape is provided instead of the protruding plate 16 (difference 2), and
The difference is that a hook portion 72 is provided in place of the screw hole 6 at the lower end of the flange 5 (difference 3).

Next, the difference 1 will be described. In the third embodiment, ribs 71, which are protrusions in the shape of a right triangle, are formed on both sides of the hook entrance opening 4 along the longitudinal direction of the hook entrance opening 4. The ribs 71 are engaged with the frame member to reduce deformation of the hook intrusion opening 4 when the heat insulating material D is filled and foamed. Although there are various types of frame members, in the frame member W8 shown in FIG. 5 (a), the contact portion 18 with which the flange 5 of the pin device P abuts is a concave portion that has not been found in the prior art. A pair of engagement grooves 73 are formed. The pair of engagement grooves 73 have a size corresponding to the rib 71, and the rib 71 engages as shown in FIG.

Further, the frame member W shown in FIG. 5 (b)
3 is the same as the frame material W3 shown in FIG.
The rib 71 of the pin device P contacts the inclined portion 57 of the frame material W3. Furthermore, the frame material W9 shown in FIG.
It is a concave frame material for m and has a shape in which a pair of contact portions 18 are provided. The frame members W1 to W8 described above are 50
It is a frame material for mm. Then, the pin device P is attached to the one contact portion 18. The pin device P is attached to the contact portion 18.
An engaging groove 73 with which the rib 71 of FIG. Then, the frame member W10 illustrated in FIG.
Is an L frame material for 100 mm, and has a shape in which a pair of contact portions 56 are provided. Then, the pin device P is attached to the one contact portion 56. The abutting portion 56 is provided with a pair of inclined portions 57 with which the ribs 71 of the pin device P engage.

In the case of the conventional example, as described in FIG. 12, when the heat insulating material is filled and foamed, the pin device P
When pressure is applied to the front wall 11 and the rear wall 12 of the pin support case 1, the hook entry opening 4 of the pin support case 1 becomes narrow as shown by the broken line. However, the third
The pin device P of the embodiment is provided with a rib 71, and since the rib 71 is engaged with the frame member, the pin device P is reinforced by the frame member. As a result, it is possible to prevent deformation of the hook entry opening 4 when the heat insulating material is filled and foamed.

Next, the difference 2 will be described. The conventional projecting plate 16 shown in FIGS. 9 and 12 is provided in an elongated rectangular shape over the entire length in the longitudinal direction of the pin device P, and its width is short. As shown in FIG. When attached to the face material N, the end portion of the protruding plate 16 is a face material N.
Does not come into contact with. On the other hand, the protruding plates 75 of the third embodiment shown in FIGS. 4 and 5 have an elongated trapezoidal shape, and a pair of protruding plates 75 are provided at a distance from each other. In this way, a space is formed between the projecting plates 75, and this space serves as the heat insulating material passage 76. That is, as shown in FIG. 8, through the outside of the protruding plate 75 and the heat insulating material passage 76,
As shown by the arrow, the heat insulating material D is filled in the space between the projecting plate 75 and the frame material W.

Further, the width of the protruding plate 75 is larger than that of the conventional protruding plate 16, and as shown in FIG. 8, when the frame member is attached to the face material N, the end portion of the protruding plate 75 has the face material N. Abut. Then, when the frame member is attached to the face member N placed on the jig base 48 (see FIG. 12), the pair of projecting plates 75 have a function of a supporting member that supports the pin device P. Therefore, in the case of the conventional example shown in FIG. 12, the frame member W1 could not stand on its own when the heat insulating panel 53 was manufactured, but in the case of this embodiment, it should stand by the protruding plate 75. Since I can do it, I rarely fall.

Further, the projecting plate 75 is formed substantially parallel to the flange 5 as a contact surface for contacting the frame member of the pin device P, and when the hook device 31 pulls the pin device P outward, Protruding plate 75 buried in heat insulating material D
Resists the pulling force. Therefore, the protruding plate 75
Has a function of preventing the pin device P from coming off.

Next, the difference 3 will be described. In the case of the third embodiment, the hook portion 72 at the lower end of the flange 5 is used.
Is inserted into and engaged with an engagement hole (not shown) formed in the frame member. By this engagement, the lower portion of the pin device P is attached to the frame member instead of the conventional screw stopper.

As described above, in the first or second embodiment, the hook passage opening of the frame member to which the pin device P or the hook device F is attached is limited to the portion through which the hook member 31 passes. The passage opening can be made small, and the strength of the frame material can be improved. as a result,
It is possible to reduce the deformation of the hook passage opening when the heat insulating material is filled and foamed. In particular, when the hook member 31 has a general shape, the pin 2 in the frame member
Since the hook member does not move to the portion facing to, the connecting portion is preferably provided to the portion of the frame material facing the pin.

Further, in the third embodiment, since the projecting plate 75 as a supporting member is plate-shaped and is provided substantially parallel to the flange 5 which is a surface contacting the frame member, the pin device is provided. The function of preventing P from coming off from the heat insulating panel 53 increases. Therefore, the projecting plate 75 can have a function as a supporting member and a retaining function for the pin device P. In addition, the heat insulating material passage 76 is provided in the protruding plate 75.
Since the heat insulating material is formed, the heat insulating material can easily flow into the space between the projecting plate 75 and the frame material, and the heat insulating material can be prevented from being insufficiently filled.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims. It is possible to make changes. A modified embodiment of the present invention is illustrated below.

(1) In the first and second embodiments, the pin device P is attached to the frame member to which the pin device P is attached.
Although the hook passage opening 64 used when the second pin is inserted and fixed in the gas vent hole 14 is formed, the pin device P may be of a type in which the second pin cannot be inserted. In this case, it is not necessary to form the hook passage opening 64. Although only one hook passage opening is provided, both sides of the frame member facing the pin 2 are connected to each other to form a connecting portion 61.

(2) In the third embodiment, the elongated ribs 71, which are the projecting portions, are formed so as to project on both sides of the flange 5 forming the surface of the pin device P on the frame material side.

It is also possible to form a plurality of protrusions along the hook entrance opening 4.
Further, the concave portion formed corresponding to the protruding portion may be formed in another shape instead of the engaging groove 73.

(3) In the third embodiment, the pair of projecting plates 75 as the supporting members of the pin device P are formed, but the supporting members of the pin device P may be rod-shaped, and the number thereof is also appropriate. It can be changed. However, the plate-like shape increases the function of preventing the pin device P from coming off from the heat insulating panel 53. Further, the heat insulating material passage 76 is formed by cutting between the projecting plates 75, but it can also be used as a heat insulating material passage by forming an opening in the projecting plate 75 which is a support plate. It is also possible to provide a plurality of heat insulating material passages 76.

(4) In the embodiment, the pin support case 1 and the hook storage case 25 are made of synthetic resin material, but may be made of metal such as sheet metal. (5) In the embodiment, the frame material W is made of a vinyl chloride frame or the like, but the material can be changed as appropriate, and for example, another synthetic resin frame or a metal frame can be adopted.
Further, a stainless plate, a steel plate, or the like is used as the face material, but the material or the like can be changed appropriately.

[0050]

According to the present invention, since the length of the hook passage opening of the frame member to which the hook device is attached is made shorter than the length of the hook projecting opening, the hook device as in the prior art. As compared with the case where the opening is formed so as to match the hook projecting opening, the strength of the frame material is less decreased by forming the opening. Therefore, the deformation of the frame material when the heat insulating material is filled and foamed can be reduced. As a result, it is possible to prevent the hook passage opening from being narrowed to prevent the passage of the hook member, or prevent the hook passage opening from widening and causing leakage of the heat insulating material.

Further, in the present invention, since the connecting portion for connecting the both sides of the frame member to each other is formed at the portion of the frame member substantially facing the pin of the pin device, the frame member formed by forming the opening is The decrease in strength is reduced. Therefore, similarly to the frame member to which the hook device is attached, it is possible to reduce the deformation of the frame member when the heat insulating material is filled and foamed, and the opening for hook passage is narrowed to prevent passage of the hook member or the passage of the hook member. It is possible to prevent the opening for use from expanding and causing leakage of the heat insulating material.

Further, in the present invention, since the protrusion engaging with the frame member is formed along the hook entry opening of the pin device, both sides of the hook entry opening of the pin device are reinforced by this frame member. ing. Therefore, when the heat insulating material is filled and foamed, it is possible to prevent the opening of the pin device for entering the hook from being narrowed. As a result, it is possible to reduce the obstruction of passage of the hook member and the leakage of the heat insulating material.

Further, since the frame member to which the pin device is attached has a recess, the protrusion of the pin device is securely engaged with the frame member by engaging the protrusion of the pin device with this recess. Can be held. Therefore, the positional deviation between the pin device and the frame member does not occur. As a result, the pin device can be reliably reinforced by the frame member, and the occurrence of leakage of the heat insulating material can be reduced.

Since the pin device is provided with the supporting member that is in contact with at least one of the pair of face materials, when the frame member to which the pin device is attached is assembled to the face material, This frame material is supported by the support member of the pin device. As a result, at the time of manufacturing the heat insulation panel, the frame material to which the pin device is attached does not fall down, and the heat insulation panel is easily manufactured.
