Description

[Detailed Description of the Invention] Industrial Field of the Invention This invention is for supporting a tight material such as a hinged window or door having an opening / closing member such as a hinged door or a door body that opens and closes around a pivot axis such as a hinge or a pivot hinge. Regarding the structure.

2. Description of the Related Art For example, in a door in which one side of a door body is rotatably attached to an opening frame by a hinge, a tight material holder is provided around the inner circumference of the opening frame, and when the door body is closed, the interior surface of the door is closed. Airtightness inside and outside the room (hereinafter, simply referred to as airtightness) is achieved by contacting the tight material. Further, the contact strength between the door body and the tight material when the frame body is in the locked state was the same at any position on the four circumferences of the opening frame.

However, particularly in the door for shutting off the inside and outside of the room, the wind and rain blown against the lower part of the door, the rainwater bounces off, and the wind blows heavily, and the airtightness of this part may become unstable.

On the other hand, if the contact between the door body and the tight material is strong at any place, a force is required at the time of locking and the tight material becomes expensive in terms of durability. Moreover, it is troublesome and costly to make only the lower frame part a special tight material.

This invention can use the same thing as the other parts as the tight material of the lower frame, and when the opening / closing body is closed, the tight material of the lower frame and the opening / closing body are different from other parts. It is an object to provide a tight support structure such as a door that abuts strongly.

MEANS FOR SOLVING THE PROBLEM A structure such as a door is attached to a groove-shaped tight material holder formed on four circumferences of an opening frame by rotatably mounting an opening / closing body such as an opening door or a door body on the opening frame. A tight material is attached that has a contact portion for the opening / closing body that is larger than the width of the groove opening. The contact portion forms a space with the tight material holder, and the opening / closing body abuts the indoor surface at the contact portion. Shall be sealed.

A supporting portion that supports the contact portion of the tight material from the indoor side is formed in the tight material holder in the lower frame of the opening frame.

The support portion of the tight material holder of the lower frame supports the contact portion of the tight material from the indoor side, and strengthens the contact between the opening / closing body and the tight material in the lower portion of the door or the like.

Embodiment The figure shows a terrace door in which a door body 2 is rotatably supported by a hinge 3 on a door frame 1.

The door frame 1 has a structure in which upper and lower frames 4 and 5 and left and right vertical frames 6 and 7 formed by extrusion molding are assembled in a rectangular shape, and a door body 2 has upper and lower frames 8 and 9 and left and right vertical frames. The door body 2 has a structure in which 10 and 11 are framed in a rectangular shape and glass is mounted, and the door body 2 is supported by the right vertical frame 7 of the door frame 1 by the hinge 3 on the right vertical frame 11 on one side.

The door frame 1 is one of the opening frames, and the door body 2 is one of the opening / closing bodies.

The upper frame 4 is provided with a tight material holder 13 on the inner periphery near the indoor side via the fins 12, and the lower frame 5 is provided with a tight material holder 15 above the rising wall 14 near the indoor side.

Tight material holders 17 and 19 are formed on the inner peripheries of the left and right vertical frames 6 and 7 close to the indoor side via fins 16 and 18, respectively.

These tight material holders 13, 15, 17, and 19 are arranged around the inner peripheral side of the door frame 1 and support a continuous tight material 20.

Each of the tight material holders 13, 15, 17, 19 is basically continuous in the longitudinal direction as shown in FIG.
Has an open groove 21 and, in cross section, groove walls 22 on both sides
a (outer peripheral side) and 22b (inner peripheral side) are bent in a hook shape facing each other on the outdoor side, and receiving wall 23a (outer peripheral side) 23b (inner peripheral side)
It has the structure

However, specifically, the tight material holder 13 of the upper frame 4 has a protrusion 24b (support portion) extending in the longitudinal direction on the outdoor side surface of the receiving wall 23b on the inner peripheral side, as shown in FIG. 4 (a). However, the tight material holder 15 of the lower frame 5 has protrusions 25a, 25b extending in the longitudinal direction at the same height on the outdoor side surfaces of the outer and inner receiving walls 23a, 23b as shown in FIG. The groove wall 22b on the inner peripheral side is an extension piece 26 projecting from the projection 25b to the outside of the room.

It should be noted that the extension piece 26 is for preventing a person who enters or leaves the door from stepping on the tight material and dropping the tight material from the holder.

The tight material holder 17 of the left vertical frame 6 and the tight material holder 19 of the right vertical frame 7 have the same basic shapes as described above, and neither of the receiving walls 23a and 23b has a protrusion.

These tight material holders 13, 15, 17, 19 are arranged such that the receiving walls 23a, 23b of the respective holders are aligned along the mounting surface s (FIG. 2) of the door frame 1 and are mounted on the tight material 20. Is in close contact with the interior surface of the door body 2 which is closed over its entire length.

The tight member 20 is made of a weatherproof material having elasticity such as synthetic rubber, and has an abutting portion 28 (Fig. 3) larger than the opening width of the groove 21 of the tight material holder, a fitting portion 29, and a width wider than these. Has a narrow connecting portion 30, and the abutting portion 28 has a shoulder portion in cross section.
31 (31a, 31b) are formed and connected to the connecting portion 30.
The tight member 20 has a well-known cross-sectional shape, and has the same cross-section over the entire length.

The tight material 20 is mounted by immovably fitting the fitting portion 29 into the groove 21 of each of the tight material holders 13, 15, 17, 19 described above. The shoulder portion 31 of the abutting portion 28 forms a space g between the abutting portion 28 and the receiving wall 23 while allowing the inclination of the abutting portion 28 while being floated from the receiving walls 23a and 23b by the connecting portion 30. .

Then, in the tight material holder 15 of the lower frame 5, the tight material 20
The outer peripheral side shoulder portion 25a and the inner peripheral side shoulder portion 25b of the contact portion 28 of
Are both supported from the indoor side by the shoulder portions 23a and 23b of the holder.

Further, in the tight material holder 13 of the upper frame 4, the inner peripheral side of the contact portion 28 is supported from the indoor side by the ridge 24b.

In the tight material holder 17 of the left vertical frame 6 and the tight material holder 18 of the right vertical frame 7, the space g between the abutting portion 28 and the receiving walls 23a and 23b is not supported on both the outer peripheral side and the inner peripheral side. Has become.

A guide arm 32 is arranged between the door frame 1 and the door body 2 between the upper frame 4 and a lock side support mechanism 33 between the door frame 2 and the lower frame 5.

One end of the guide arm 32 is rotatably supported in the middle of the upper frame 4 in the longitudinal direction, and the other end is slidably supported in a guide groove 34 of the upper frame 8 of the door 2 via a guide roller 35. .

The lock-side support mechanism 33 includes a metal fitting 36 fixed to the draining surface of the lower frame 5 and a support roller 37 pivotally supported by the lower frame 9 of the door 2.
The roller 37 has a structure in which the outdoor side slope 38 of the receiving metal fitting 36 is used as a guide to ascend slightly to reach the top surface 39.

Further, the receiving fitting 36 is also provided with a hole for receiving the tip of a drop rod which is attached to the lower frame 9 and can be operated from the indoor side.

Now, when the door body 2 is closed, the door body 2 rotates around the hinge 3 and is housed in the door frame 1, and the support roller 37 at the lower portion of the lower frame 9 is guided by the slope 38 of the receiving metal fitting 36 and the top surface 39. Up to the indoor side surface of the door body 2, that is, the indoor side surfaces of the upper, lower, left and right frames 8,9,10,11 and the upper and lower sides of the door frame 1, the left and right frames 4,5,6,7. (Attached to the material holders 13, 15, 17, 19) are in a state of light contact. Then, when the door body 2 is locked by the lock device 40, the door body 2 is further drawn to the door frame side, the inner surface of the door body strongly adheres to the tight material 20, and the inside and outside are airtightly isolated.

At this time, the tight material 20 in the upper frame 4 and the left and right vertical frames 6 and 7
When the abutting portion 28 is pressed by the door body 2, the door body 2 and the tight member can be escaped by inclining to the space g (which exists on one side or both sides) on the indoor side to some extent.
The abutment of 20 is enough to keep the part airtight, but not so strong. Therefore, when the door body 2 is locked, the resistance in these parts is small.

On the other hand, in the place of the tight material holder 15 of the lower frame 5,
In the cross section, since the outer peripheral side and inner peripheral side shoulder portions 31a and 31b of the contact portion 28 of the tight material 20 are both supported from the indoor side by the protrusions 25a and 25b, the contact portion 28 of the tight material 20 becomes unnecessary. It does not incline and stably maintains a close contact with the door body 2. As a result, the lower part of the door and the lower frame 5, which require high performance,
The airtightness between them is satisfied.

In the lower frame 5 of this embodiment, the extension piece 26 is made of a tight material.
The inner peripheral side of 20 is supported and the tight material is prevented from escaping in that direction, so that the adhesion is further enhanced.

Further, in the door structure, the tight material 20 on the hanging side is the door body 2
Since it will be deformed or damaged at the corners on the indoor side of the vertical frame 11 at, the so-called dust will usually be taken large when the door body 2 is mounted, or the tight material of this part will be separated from other parts such as mohair. Are different,
In the present embodiment, the tight member 20 in the right vertical frame 7 on the hanging side forms the space g between the shoulder portions 31a and 31b of the contact portion 28 and the receiving walls 23a and 23b of the holder facing the shoulder portions 31a and 31b. Even if the vertical frame 11 hits the tight material 20 when the door body 2 is opened and closed (that is, there is no support portion), the tight material 20 easily tilts and escapes, so the tight material 20 strongly bends on the door body 2. There is no need to be. On the other hand, since the door body 2 rotates without receiving the strong resistance when the tight material 20 is pressed, the opening / closing operation is light.

That is, the door body 2 can be opened and closed without winding the tight material 20 attached to the tight material holder 19 on the suspension side.

The above is the embodiment, and in the present invention, the shapes of the tight material holders 13, 15, 17, 19 and the tight material 20 are the same as those of the tight material 20.
Is larger than the opening width of the groove in the holder, and between the abutting portion 28 of the tight material 20 and the tight material holder 15 at the portion of the lower frame 5, the abutting portion 28 is on the indoor side. Any material can be used as long as it can form a supporting portion for supporting the.

As in the example, when the left and right vertical frames 6 and 7 can be formed from the same mold material, if they are formed from an extruded molding material without a support,
Even when the suspension source of the door body 2 is changed to the left or right, it is not necessary to separately prepare a frame material for the vertical frame.

Since the support portion may be provided on the inner peripheral side receiving wall 23b of the tight material holder 17 of the left vertical frame 6 on the lock side, the left and right vertical frames 6 and 7 are provided on the receiving wall 23a of the tight material holders 17 and 19. , 23b
It is also possible to provide ridges on both sides in advance and cut off or cut off if necessary. Even in this way, the same extruded material can be used for the left and right vertical frames.

As shown in FIG. 5, the wall thickness of the receiving wall 23a and / or 23b in the tight material holder may be increased instead of the protrusion (25a etc.).

Effect of the Invention In a door or the like, the airtightness between the opening / closing body and the opening frame is strengthened at the lower part.

Rotation of the opening and closing body is light.

The same material as other parts can be used for the tight material of the lower frame, the number of parts can be reduced, and the cost of the product can be reduced.
