Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel connecting device for connecting, for example, a heat insulating panel of a prefabricated refrigerator.

[0002]

2. Description of the Related Art Conventionally, a panel coupling device of this type is composed of one locking flat body and the other locking flat body, as disclosed in, for example, Japanese Utility Model Publication No. 57-4167 (E04B1 / 40) as a wall material connecting device. The one locking flat body is attached to one wall material, the other locking flat body is attached to the other wall material, and the tip of the hook provided rotatably in the one locking flat body is engaged with the other locking flat body. Both wall members are connected by being locked to the stop rod.

The one-side locking flat body is formed by joining two metal plates on the front and back to form a one-side flat groove chamber between the two plates, and housing the tip key piece in the groove chamber. If the tip hook unnecessarily projects from the groove chamber except when the wall material is joined,
Since there is a risk of contact with other wall materials or the like to be deformed, they are locked and held in place in the groove chamber by the reinforcing horizontal rod.

In the following, the one locking flat body of the above publication is a coupling tool 100, the front and back metal plates are a front plate body 101, a back plate body 102, a tip key piece is a hook 103, a groove chamber is a storage chamber 104, and a reinforcing horizontal rod. Is used as the locking portion 105, and the conventional structure according to FIG. 6 will be described. That is, the conventional locking portion 105 is composed of a metal pin, and when the coupling device 100 is assembled, the hook 103 is first placed on the back plate 102 at a predetermined position of the storage chamber 104. Back plate 1 in that state
02, the front plate body 101 is covered, and the both plate bodies 101 and 102 are joined, and then the locking portion 105 is inserted over the holes 106 and 107 formed in the both plate bodies 101 and 102, and the whole is caulked and fixed. Was configured.

[0005]

The hook 103 is unnecessarily placed at a predetermined position in the storage chamber 104 by the stepped portion (not shown) formed on the hook 103 being releasably locked to the locking portion 105. Although it is locked and held so as not to project from the storage chamber 104, the tip of the hook 103 is lowered downward (to the back plate body 102 side) by gravity when the hook 103 is placed on the back plate body 102 during the assembly. However, as shown by the alternate long and short dash line in FIG. 6, it is not located in the central portion between the two plate members 101 and 102 but is displaced to the back plate member 102 side. When the hook 103 is thus deviated in the storage chamber 104, when the hook 103 is projected from the coupling tool 100 to couple the wall material, the hook 103 comes into contact with the edge of the other coupling tool and the coupling is performed. There is a problem that the engaging portion inside the tool cannot be engaged.

Further, since the number of parts for mounting the locking portion 105 increases, the number of assembling steps also increases, and when inserting the locking portion 105, both holes 106, 107 and the step of the hook 103 between them are provided. Since it has to be inserted in a state in which the attached portion and the attached portion are arranged in a straight line, positioning becomes extremely difficult and assembly workability is significantly deteriorated.

The present invention has been made in order to solve the above-mentioned conventional technical problems, and eliminates the deviation of the hooks in the storage chamber, and is excellent in the assembling workability and can reduce the cost. It is intended to provide a coupling device.

[0008]

The panel connecting device 1 of the present invention comprises one connecting member 2 and the other connecting member 4, one connecting member 2 being attached to one panel P1 and the other connecting member. 4 is attached to the other panel P2, and the hooks 15 provided in the one coupling tool 2 are engaged with the engaging portions 37 provided in the other coupling tool 4 to both panels P2.
1 and P2 are joined together, and one joining tool 2 is a plate body 6 and 7 having two front and back surfaces joined to each other and both plate bodies 6 and 7.

This locking portion 3 is formed so as to project toward the storage chamber 13 side with an inclination from both plate bodies 6 and 7, and is abutted to each other at a substantially central portion between both plate bodies 6 and 7. Projections 25 and 26
It is characterized by being configured by.

[0009]

According to the panel connecting device 1 of the present invention, the protrusions 25 and 2 of the two front and back plate bodies 6 and 7 constituting the one connecting tool 2 are formed.
Since the locking portion 3 is constituted by 6, the number of parts and the cost can be reduced. Further, the presence of the projections 25 and 26 enables the hook 15 to be positioned and temporarily held on the plate bodies 6 and 7 during assembly. After that, only the front and back plate bodies 6 and 7 are joined to each other to assemble one coupling tool 2. In particular,
There is no need for the conventional work such as pin hole matching, and assembly workability is also improved. Further, the protrusion 2 that constitutes the locking portion 3
5 and 26 incline and project from the plate bodies 6 and 7,
Since they are abutted against each other at a substantially central portion between the plates 7, the hook 15 is guided to the substantially central portion between the plates 6 and 7 by the inclination of the protrusions 25 and 26 at the stage of joining the plate bodies 6 and 7. , Will be held in the storage chamber 13.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a partially cutaway front view of a panel coupling device 1 of the present invention, FIG. 2 is a side view of one coupling tool 2, FIG. 3 is an enlarged vertical sectional view of a locking portion 3, and FIG. 4 is a perspective view of a panel P1. FIG. 5 and FIG. 5 are views for explaining the work of joining the panels P1 and P2.

In each of the drawings, the panel connecting device 1 of the present invention is shown.
Is composed of one coupling tool 2 and the other coupling tool 4. The coupling tool 2 is constructed by joining two front and back plate bodies 6 and 7 each made of a metal plate, and they are integrated by caulking at caulking portions 8 and 9 as indicated by broken line arrows in FIG. .
Swelling portions 11 and 12 projecting outward are formed at substantially central portions of the plate bodies 6 and 7 which face each other, and the caulking portions 8 and 9 are present at outer peripheral portions of the swelling portions 11 and 12. is doing. A groove-shaped storage chamber 13 is formed between both bulging portions in a state in which both plate bodies 6 and 7 are joined in the coupling tool 2. The storage chamber 13 has an opening 10 on the right side in FIG. The rotor 14 and the hook 15 made of a metal plate are rotatably housed therein.

The hook 15 has a circular hole (not shown) at its center, and the rotor 14 is composed of a pair of plates having circular recesses smaller than the hole. The rotor 14 locates the recessed portion in the hole. And is attached to the hook 15 in such a manner that the periphery of the hole is held between the hooks 15. That is, the peripheral portion of the rotor 14 is rotatably in contact with the hook 15 with a predetermined frictional force, and rises in the direction of the plates 6 and 7 at a position eccentric downward from the center of the circle to make the inner surface hexagonal. The base 16 is formed. On the other hand, through holes 17, 17 are formed in the plate bodies 6, 7, and the through holes 17, 17 are formed.
When the base 16 is pivotally inserted into the rotor 1,
4 and the hook 15 are rotatably held in the storage chamber 13.

The hook 15 is a hook-shaped portion 19 protruding in the radial direction of the rotor 14 from the portion where the rotor 14 is attached.
And a stepped portion 20 formed on the rear side of the base portion of the hook-shaped portion 19, and convex portions 21 and 22 formed upright at opposing positions around the circular hole. On the periphery of the hole of the hook 15, there is provided an overhanging portion 23 that overhangs in the radial direction. And this overhang 23
Are in a positional relationship of abutting on the convex portions 21 and 22 as the rotor 14 rotates.

Here, the bulging portions 11, 1 of the front and back plate bodies 6, 7
As shown in FIG. 3, a part of 2 is inclined and pushed toward the storage chamber 13 in a substantially frustoconical shape, so that a pair of protrusions 25,
26 is formed. The protrusions 25 and 26 are plates 6 and 7.
They are abutted against each other at a substantially central portion between them, and they form the locking portion 3. The stepped portion 20 of the hook 15 meshes with the locking portion 3 when the hook 15 is stored in the storage chamber 13, and the hook 15 is retained by the locking portion 3. Further, in this state, the overhanging portion 23 of the rotor 14 contacts the front surface of the convex portion 21 of the hook 15. Further, the front and back plate body 6,
A bent piece 27 is formed on the rear edge of the bent piece 7 so as to project to the left and right.

The other coupling tool 4 is also constructed by joining two front and back plate bodies 29 and 30 made of metal plates, and they are integrated by caulking with caulking portions 31 and 32. Swelling portions 33 and 34 that project outward are formed in the central portions of the plate bodies 29 and 30 that face each other, and the swaging portions 31 and 32 are formed.
Exists on the outer peripheral portion of the bulging portions 33 and 34.
A groove-shaped storage chamber 35 is formed between the bulging portions in the coupling tool 4 in a state where both plate bodies 29 and 30 are joined.
One side of the left side 5 of FIG. 1 is open at an opening 36, and a metal pin 37 as an engaging portion is attached to the inside thereof. In addition, bent pieces 38 that extend to the left and right are also bent and formed at the rear edges of the front and back plate members 29 and 30.

Next, a procedure for assembling the one coupling tool 2 will be described. First, the pre-assembled hook 15 and rotor 14
Is placed on the back plate 7. At this time, as shown in FIG. 1, the base portion 16 of the rotor 14 is inserted into the through hole 17 of the back plate body 7, and the projection 26 is positioned inside the stepped portion 20 of the hook 15. The periphery is located at the tip of the protrusion 26. As a result, the hook 15 (the rotor 1
(Including 4) with respect to the plate body 7 and temporary holding are achieved. Next, the front plate body 6 is covered. At this time, the base portion 16 of the rotor 14 is assembled so as to enter the through hole 17 of the front plate body 6, and the front and back plate bodies 6 and 7 are joined.
Further, by such a joining operation, the protrusion 25 is abutted against the protrusion 26 to form the locking portion 3, and the protrusion 25 similarly enters the stepped portion 20 of the hook 15. After that, both plate bodies 6 and 7 are crimped at the crimped portions 8 and 9 to integrate all the components.

At this time, even when the hook 15 is deviated to either one of the centers of the plate bodies 6 and 7 (usually, gravity tends to deviate toward the back plate body 7). Since the projections 25 and 26 are inclined toward the center between the plates 6 and 7, they are guided to the center by this inclination, so that the hook 15 is interposed between the plates 6 and 7 as shown by a chain line in FIG. It will be held at the position of the approximate center.

The coupling tools 2, 4 assembled in this way
Are embedded in the heat insulating material at the ends of the panels P1 and P2 as shown in FIG. At this time, the bent pieces 27 and 38 are formed so as to bite into the heat insulating material of the panel, whereby the coupling tools 2 and 4 are firmly held by the panel P1 or P2. Further, since the protrusions 25 and 26 are butted against each other, even if the foaming pressure of the heat insulating material is applied to the bulging portions 11 and 12, the crushing can be prevented with sufficient strength. Further, the heat insulating material of the panel P1 is cut out so that the through hole 17 of the plate body 6 and the base portion 16 of the rotor 14 can be seen from the outer surface of the panel P1.

Next, when the panels P1 and P2 are to be joined together, as shown in FIG. 5, both panels P1 and P2 are abutted against each other, and both joining tools 2 and 4 are opposed to each other. Next, a rotating rod 40 having a hexagonal cross section as shown in FIG. 5 is inserted from the outer surface of the panel P1,
It is engaged with the base portion 16 of the rotor 14 and rotated clockwise in FIG. 1 or 5. This rotation causes the rotor 14 to rotate clockwise in FIG. 1, but the hook 15 cannot rotate because the stepped portion 20 is locked by the locking portion 3. However, because the base portion 16 of the rotor 14 is eccentric downward in FIG. 1, the hook 15 is pulled downward,
Eventually, the stepped portion 20 moves below the locking portion 3 and escapes.
As a result, the engagement between the stepped portion 20 and the engaging portion 3 is released, the hook 15 becomes rotatable, and the frictional force with the rotor 14 causes the rotor 14 to rotate together with the rotation of the rotor 14, and the hook-shaped portion 19 at the tip thereof. Goes out of the storage room 13 and the storage room 3 of the coupling 4
Go into 5 and go.

At this time, since the hook 15 is located at the substantially central position between the plate members 6 and 7 and the deviation amount is small as described above, the hook 15 contacts the edges of the plate members 29 and 30 of the connector 4. The hook-shaped portion 19 of the hook 15 can be smoothly stored in the storage chamber 3 without touching.
5 can be entered. Eventually, when the hook-shaped portion 19 of the hook 15 comes to a substantially horizontal position as indicated by 19A in FIG. 1, the hook 15 comes into contact with the engaging portion 37 and cannot rotate. Then, when the rotor 14 is still rotated, the hook 15 is pulled to the left in FIG. 1 again due to the eccentricity of the base portion 16, and the hook-shaped portion 19 becomes the engaging portion 37 as shown by 19B in FIG. Firmly matingly engages. Both panels P1 and P2 are joined by such engagement.

In the rotor 14, the overhanging portion 23 is then the protruding portion 22.
When it comes into contact with the panel, it becomes unrotatable and the panel joining work is completed. When the panels P1 and P2 are uncoupled from each other, if the rotating rod 40 is rotated counterclockwise in FIG. 1, the rotor 14 and the hook 15 perform the reverse operation described above, and the hook 15 is the coupling tool. 2 and pulled back into the storage unit 13,
The panels P1 and P2 are uncoupled. After that, the stepped portion 20 is locked by the locking portion 3, and at this time, the hook 1
Even if 5 is slightly deviated to one side from the center between both plate bodies 6 and 7, the protrusions 25 and 26 are guided to the center so that the hook 15 is located between the plate bodies 6 and 7. It will be locked at the position of the approximate center. Finally, the overhanging portion 23 of the rotor 14 contacts the convex portion 21 and returns to the initial state.

A plurality of panel connecting devices 1 are used in one prefabricated refrigerator and are used for connecting peripheral panels. Further, in the embodiment, the panel joining device of the present invention is used for joining the heat insulation panel of the prefabricated refrigerator, but the present invention is not limited to this, and the present invention is effective for joining various wall materials.

[0023]

As described above in detail, according to the present invention, since the engaging portion is constituted by the projections of the two front and back plate bodies that constitute one coupling tool, the number of parts of the panel coupling device and the cost are reduced. It is possible to reduce. In addition, the presence of the protrusion enables positioning and temporary holding of the hook with respect to the plate body during assembly, and thereafter, one of the couplers can be assembled simply by joining the front and back plate bodies. Since no work is required, the workability of assembling the coupler is significantly improved as a whole. Furthermore, since the projections forming the locking portion are inclined and projected from the plate body and are abutted against each other at the substantially central portion between the plate bodies, the strength of the coupling itself is improved and both plate bodies are At the stage of joining, the hook can be guided to the substantially central portion between the plate bodies by the inclination of the protrusion and can be held in the storage chamber. Therefore, it is possible to eliminate inconvenience during the connecting work due to the deviation of the hooks in the storage chamber and to smoothly achieve the panel connecting work.
