Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an airtight device between a hinged door and a door frame portion for suspending the hinged door.

(Prior art and its problems) Generally, for airtightness between a door frame and a hinged door suspended inside the door frame, an airtight member is attached to a door contact portion provided around the door frame, and the hinged door is brought into contact with the airtight member. It is done by letting it.

However, since the door contact portion is integrally formed with each of the upper and lower parts and both side parts of the door frame, for example, when assembling the door frame or when mounting the assembled door frame in the building, it is assembled between the frames. If an error or an installation error occurs, the door contact surface of the door contact part may not be flush.Therefore, even if the hinged door is hung on such a door frame, a gap is created between the airtight material and the hinged door. As a result, air tightness occurs. In such a case, there is a drawback that the work is complicated and the construction is delayed because the assembly and the mounting must be redone.

(Technical problem of the invention) It is a technical problem of the present invention to provide an airtight device for a hinged door, which eliminates the above-mentioned drawbacks and makes the door-contacting surface of the door-contacting part flush with the hinged door easily and accurately. And

(Means for Solving the Problem) In order to solve the above problems, an airtight device for a hinged door according to the present invention is provided with a door frame portion for housing a hinged door and a door stop portion of the hinged door, and the door stopper portion is provided with the above In an airtight device for a hinged door, which is formed by surrounding an airtight member that abuts against a hinged door, a fitting leg portion that is continuous in the longitudinal direction is formed at the base of the airtight member, and the fitting leg portion is locked to the door contact portion. While fitting into the groove, the fitting leg portion has a width slightly larger than the opening width of the locking groove, and the fitting leg portion has a long adjustment width in the fitting direction, and the side surface of the fitting leg portion is provided with a concave-convex line, The fitting leg is press-fitted into the locking groove to hold it in the locking groove at an appropriate adjustment position.

(Operation and Effect of the Invention) According to the above configuration, the airtight member is configured such that the fitting leg portion of the airtight member is press-fitted into the locking groove of the door stop portion, and the fitting leg portion is slightly wider than the opening width of the locking groove. Since the airtight material has a large width and a long adjustment width in the fitting direction, and the side surface is provided with uneven ridges, the airtight material can be pushed or pulled out to an arbitrary width at any position in the longitudinal direction. The degree of press-fitting can be adjusted, and the fitting leg is held in the locking groove as it is. Therefore, for example, it is possible to make an adjustment such that the width of the airtight member is made small at one end of the door contact portion, gradually increased and maximized at the other end. Therefore, it is possible to finely adjust the airtightness according to the state of the hinged door housed in the door frame portion to accommodate various conditions.

A door frame part c is formed by the lower frame 2 and the lower frame 2, and a hinged door 8 is accommodated in the door frame part c and is suspended from the side frame 3 by a hinge 9. And, the hinged door 8 has a door stop 11
Is provided, and the airtight member 10 that abuts against the hinged door 8 is provided around the door contact portion 11, thereby forming an airtight device.

Next, the airtight device of the hinged door 8 will be described in detail.

First, in the door frame portion c, the indoor end of the inner peripheral wall surface of the hinged door housing portion projects inward to form a door contact portion 11 of the hinged door 8. Each of the door contact portions 11 is a frame body 5a, 4a, 3a, 2a that constitutes the middle frame 5, the seamless frame 4, the side frame 3, and the lower frame 2.
And a door stop member 20 to which the airtight material 10 is attached.

In each of the frame main bodies 5a, 4a and 3a of the middle frame 5, the seamless frame 4 and the side frame 3, a fitting groove 14 opening to the indoor side is formed on the outdoor side of the inner wall surface of the hinged door housing portion 12. In addition, the accommodation section
The indoor end of 12 projects inward, and an engaging piece 16 projecting to the outdoor side is formed at the inner end of the projecting portion 15, whereby the indoor side of the accommodating section 12 and the outdoor side are formed. A fitting groove 17 that opens is formed.

On the other hand, as shown in FIG. 6, the door stop member 20 has a screw hole 18 formed in the middle portion of the long piece 20a of the L-shaped plate-like member and is engaged along the side end portion of the short piece 20b. Forming a stop groove 19,
The airtight material 10 is fitted and mounted in the locking groove 19.

The door contact portion 11 locks the side end of the long piece 20a of the door contact member 20 into the outdoor fitting groove 14 of the middle frame 5 and the frame bodies 5a and 4a of the blind 4 and fits the short piece 20b on the indoor side. Locked in dowel groove 17 and 2 long pieces
0a is screwed to the accommodating portion 12, and similarly the side frame 3 and the frame 2
The door stop member 20 is screwed onto the frame bodies 3a and 2a.

Next, the airtight member 10 is composed of a door receiving portion 10a for receiving the hinged door 8, a fitting leg portion 10b fitted in the locking groove 19 of the door contact member 20, and a tapered engaging projection 10c. The door receiving surface of 10a is formed of a soft synthetic resin, the fitting leg portion 10b is formed of a semi-hard synthetic resin, and a hollow portion 22 is provided inside thereof.

The size of the fitting leg portion 10b is the opening edge 2 of the locking groove 19 of the door stop portion 11.
The fitting leg portion 10b has a slightly larger width than the opening formed between the spaces 3 and 23, and the fitting leg portion 10b has a long adjustment width in the fitting direction. This allows the mating leg 10
The degree of press-fitting and fitting can be adjusted by pushing and pulling out b into the locking groove 19, and in this case, the airtight member 10 can be held at any position in the longitudinal direction and at any width.

In the above configuration, in order to make the door contact surface of the door contact portion 11 with respect to the hinged door 8 flush, the door receiving portion 10a of the door contact member 20.
The fitting dimension of the airtight material 10 into the locking groove 19 of the door-contact part 11 may be adjusted while observing the door-contact state of the air-tight material 10 so that no gap is created with respect to the hinged door 8. Mating leg 10b
Is formed of a semi-hard synthetic resin, and is formed so as to fit tightly into the locking groove 19, and the concave-convex line 24 is formed into the locking groove 19.
Since it bites into the opening edge 23, the protruding state of the airtight material 10 from the locking groove 19 is maintained as it is. Therefore, for example, as shown by the solid line and the dotted line in FIGS. 2 to 4, the protruding width of the airtight member 10 is adjusted to be small at one end of the door contact portion 11 and gradually increased to the maximum at the other end. Will also be possible. Therefore, the airtightness can be finely adjusted according to the state of the hinged door 8 housed in the door frame portion c, and various adjustments can be made.

As shown in FIG. 6, the width of the long piece 20a of the door stop member 20 is made smaller than the expected width of the housing portion 12 of the frame bodies 5a, 4a, 2a, and the screw hole 18 of the long piece 20a is horizontally long. With this structure, the long piece 20a of the door stop member 20 can be moved and adjusted in the expected width direction of the frame bodies 5a, 4a, 2a. Therefore, in this case, the adjustment range can be increased by adjusting the movements of both the door contact member 20 and the airtight member 10. However, even in this case, the side end portion of the long piece 20a of the door stop member 20 of the side frame 3 does not necessarily need to be moved and adjusted. The reason is that the hinge 9 of the hinged door 8 is formed with a horizontally long hole (not shown), so that the mounting position of the hinged door 8 can be adjusted.

As described above, according to the airtight device of the hinged door, the airtight material is
10 is a structure in which the fitting leg portion 10b is press-fitted into the locking groove of the door stop portion, and the fitting leg portion 10b has a width slightly larger than the opening width of the locking groove 19 and a long adjustment width in the fitting direction. Since the airtight material 10 is provided with the concave-convex strips 24 on its side surface, the degree of press-fitting fitting can be adjusted so that the airtight member 10 can be pushed in and pulled out at any position in its longitudinal direction to have any desired width. And the mating leg 10b remains as it is and the locking groove 1
Holds at 9. Therefore, for example, it is possible to make an adjustment such that the protruding width of the airtight member 10 is made small at one end of the door stop portion 11, gradually increased and maximized at the other end.
