Description of the Related Art An airtight door such as a heat-insulated entrance door has a door and a door frame which are filled with a heat insulating material and an elastic body such as rubber is provided on either the door side or the door frame side, and the door is closed. In some cases, the projection provided on the other side is pressed against the elastic body to maintain airtightness.

FIG. 9 shows a typical example of the structure.
A concave portion 3 is formed in a stepped portion of the stainless steel door frame 1 that comes into contact with the door 2 around the entire periphery, and an elastic member 4 having a hollow inside is fitted and fixed in the concave portion 3.

Correspondingly, a projection 5 is provided on the contact surface of the door 2 with the elastic body 4, and when the door 2 is closed, the projection 5 presses the elastic body 4 while elastically deforming the elastic body 4. This provides a structure that achieves airtightness between the contact surfaces.

The cross-sectional shape of the elastic body 4 and the shape of the projections are various other than those shown in the drawings, but are generally similar.

[0006] In addition, this type of hermetic door generally eliminates errors in manufacturing the door itself and errors in building the door.
In order to ensure airtightness, there is provided a glemon device (gremon tightening) for forcibly pressing between the door and the door frame by projecting a bar up and down from the door tip side in conjunction with the operation of the handle.

[0018]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

1 to 4 show a first embodiment of the present invention. In FIG. 1, reference numeral 10 denotes a door frame, and 12 denotes a door, both of which are made of stainless steel or the like. A hanging source [a] of the door 12 is connected to the door frame 10 so as to be openable and closable by a pair of hinges 14, and a lock 16 is disposed at the door end [b]. Can be unlocked.

In FIG. 2, a door 12 has a frame formed along the outer shape of the door 12 with front and rear end plates attached thereto. The inside of the hollow is filled with a heat insulating material such as urethane foam. ing. In addition, the thickness of the door 12 is actually thicker than that shown in the figure, but it is drawn thin for easy understanding of the main part of the present invention.

A step 18 is formed inside the door frame 10 so that the door 12 abuts around the periphery of the door frame 10, and at least the hanging base [a] and the door end [b] of the step 18 are formed. A crimping member 20 is interposed along the longitudinal direction.

Further, a door stop 22 is fixed above and below the door end [b] of the door frame 10 (only one bottom portion is shown in the figure), and the inside of the door 12 abuts on this, thereby positioning the door at the time of closing. This prevents excessive compression of the crimping member 20.

The crimping member 20 is a hollow integral extruded product made of a material such as rubber, and as shown in detail in FIG. 3A, a plate portion 24 fixed to the step 18 and a door 12 A contact portion 26 which stops on the side, a bellows portion 28 which is located on the inner side between the two and integrally connects the two, and is formed along the longitudinal direction at an opposite end portion of the bellows portion 28. Extending from the contact portion 26 and the slit 30,
A tongue piece 32 for closing the slit 30 when the door is closed, and a magnet sheet 3 inside the contact portion 26.
When the door is closed, it is attached to the door 12 to maintain airtightness.

In order to fix the crimping member 20 to the step portion, a screw 36 is used.
As shown in (b), if the bellows portion 28 is used as a hinge and the slit 30 is opened widely, the plate portion 24 is exposed, and the screw 36 can be screwed and fixed using the driver D in this state. Thereafter, the compression member 20 is restored to its original shape by the elastic recovery force.

When the door is open, the crimping member 20
FIG. 4A shows a state in which the bellows portion 28 is widened by its elasticity and protrudes toward the front side of the opening. When the door 12 is closed and locked from this state, FIG.
As shown in (2), the crimping member 20 is compressed while the bellows portion 28 is contracted, and the magnet sheet 34 provided on the contact portion 26 is attracted to the door 12 and comes into contact with the entire surface to be airtightly closed. The same expansion and contraction at the hanging side [A] maintains airtightness when the door is closed.

At the time of this closing, even if a finger is pinched between the door tip, the finger is pinched between the door 12 and the surface of the crimping member 20, and the crimping member 20 itself is in the bellows portion 28.
Due to this, the amount of expansion and contraction is large and the width of receiving the foreign matter is large, so that scratches and the like can be prevented, and the safety is extremely high as compared with the related art.

Although not shown, a rubber elastic body or other airtight holding member similar to the conventional one can be provided at the lower edge and the upper edge of the four sides of the door frame 10.

FIG. 5 shows a second embodiment of the present invention. The door shown in the drawing has a large gap dimension d between the door end side end of the door 12 and the inside of the door frame 10, and a door member 40 made of an elastic extruded product of the same material as the crimping member 20 therein. Is interposed. The door tip member 40 is hollow inside and is sufficiently elastically deformed to prevent damage when a finger or the like is sandwiched in a gap.

As the mounting structure, mounting holes 42 are opened at predetermined intervals along the longitudinal direction at the front end of the door 12, and the door end member 40 is resiliently fitted into the mounting holes 42. By opening the corresponding projections 44 , mounting can be performed with a simple operation.

In addition, in the hollow interior of the door member 40,
A magnet sheet 46 similar to the above is integrally embedded in the surface facing the crimping member 20. In addition, by inverting the polarity of the magnet sheet 46 with the magnet sheet 34 on the crimping member 20 side, the two are attracted to each other,
As a result, the suction force at the time of closing the door 12 is enhanced. Further, in this embodiment, the magnet sheet 46 is embedded in the door member 40, but the magnet sheet 34 on the crimping member 20 side may be merely attached to the door 12 without providing the magnet sheet 46.

FIG. 6 shows a third embodiment of the present invention. In the figure, the crimping member 20 is fixed to the door tip side of the door 12 along the vertical direction. In this embodiment, when the door is closed, the magnet sheet 3 of the crimping member 20 is closed.
The door 4 keeps the door 12 in a closed state by abutting on and adsorbing to the step of the door frame 10, so that the same sealing effect as in the first embodiment can be obtained. Further, in this embodiment, there is an advantage that the replacement operation can be easily performed by providing the pressure bonding member 20 on the door 12 side.

FIGS. 7 and 8 show a fourth embodiment of the present invention. In the figure, a concave portion 50 is formed in the inner step portion of the door frame 10 in the same manner as in the related art. A press-fit member 52 made of an extruded body is fixed.

The crimping member 52 includes an elastic fixing portion 54 fitted and fixed in the concave portion 50, a pair of bellows portions 56 integrated in a hollow state on both ends of the elastic fixing portion 54, and a pair of bellows portions 56. Plate-shaped door stop 58 integrated at the tip
And a magnet sheet 60 integrally fitted into a concave portion formed on the surface of the door stop portion 58.

The elastic fixing portion 54 substantially corresponds to the height of the concave portion 50, and a plurality of locking tongue pieces 54a for preventing slipping are integrally formed on both sides thereof. The locking tongue 54a is inclined toward the fitting direction, is inserted while being elastically deformed along both inner side walls of the concave portion 50 in the inserted state, and has a stronger frictional resistance in the pulling-out direction. Once fitted, the elastic fixed portion 54 is prevented from coming off.

Therefore, in this embodiment, the bellows portion 56 expands and contracts by opening and closing the door 12, and the entire surface of the door stop portion 56 is expanded and contracted by the magnetic force of the magnet sheet 60, similarly to the above-described embodiments. It comes into close contact with the inside of the door 12. Note that the magnet sheet 60 is
Since it comes into direct contact with 2, the suction force is further improved as compared with the above embodiments.

Further, when attaching and detaching the crimping member 52, fixing means such as screws are not required. When attaching, the fitting is stably fixed by fitting and pushing. Further, at the time of removal, it is easy to remove by inserting a flat-blade screwdriver or the like into the gap and prying it apart, so that there is an advantage that the replacement work can be simplified and the number of parts can be reduced.

In the first to third embodiments, the magnet sheet is embedded in the crimping member. In the fourth embodiment, the magnet sheet is exposed from the crimping member. May be provided so as to be exposed from the crimping member, or the magnet sheet may be embedded in the crimping member in the fourth embodiment.

Further, in each of the above embodiments, the number of folded back portions of the bellows portion is set to about two to three steps. However, the present invention is not limited to this. It goes without saying that the folding width dimension is not limited to the illustrated one.

[0039]

As described above in detail in each embodiment, in the first aspect of the present invention, airtightness when the door is closed can be maintained and there is no sharp edge. For this reason, even if a finger is sandwiched, the pressing member is prevented from being damaged due to deformation, so that safety can be greatly improved as compared with a conventional airtight door. Further, since the bellows is elastically deformed due to expansion and contraction, even if it repeatedly expands and contracts, the fatigue is small, so that the replacement period can be lengthened.
Furthermore, at the time of closing, in the hollow interior of the door member,
A magnet is integrally embedded in the surface facing the crimping member,
Reverse the polarity of this magnet to the magnet on the crimping member side
By doing so, the two are attracted to each other, and when the door is closed
The attraction force of the magnet is enhanced, and the closed state is maintained by the attraction force of the magnet. Therefore, there is an advantage that a glemon device is not required and the device can be provided at low cost.

In the invention according to claim 2 of the present invention, the door frame is fixed to at least the abutting surfaces of the four sides of the door frame on the hanging side and the door end side with the door.
Ru can be made to correspond to the many locations of the most finger-justified accident.

According to the third aspect of the present invention, there is an advantage that the expansion and contraction of the crimping member can be evenly performed and the work at the time of fixing the bolt can be easily performed.

According to the fourth aspect of the present invention, since the crimping member can be prevented from being excessively expanded and contracted, fatigue of the material due to repeated opening and closing can be prevented, and the replacement time of the crimping member can be extended. There is.
