Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door frame provided with an airtight packing, and the door is directly attached to the door frame even when the door is not correctly attached to the door frame. Used to prevent contact with and damage.

[Conventional technology]

In a conventional door frame provided with a packing for airtightness, the packing grooves provided in the upper and lower horizontal frames and the left and right vertical frames of the door frame are attached so that the hollow packing does not fall off, and in the state where the door is closed, The inner surface of the peripheral portion of the door was in close contact with the hollow packing protruding from the packing groove of the door frame, and the airtightness between the door frame and the door was kept in a good state.

[Problems to be solved by the device]

When installing a hollow packing in the packing groove of the door frame to maintain the airtightness between the door frame and the door as in the conventional case,
The inner surface of the door does not uniformly press the hollow packing attached to the door frame due to a manufacturing error of the door frame or each component of the door, an installation error of the door to the door frame with respect to the door frame, etc. See figure).

In this case, on the side where the pressing force against the packing is weaker than that when the door is installed correctly, the airtightness between the door frame and the door is slightly worse, and on the side where the pressing force against the packing is stronger, the inner surface of the door is Is greatly deformed to directly contact the metal door frame, and the contact surface is easily damaged. Moreover, the occurrence of this damage has a disadvantage that the evaluation of the product is significantly deteriorated when a decorative steel plate is used for the surface plate of the door in order to enhance the commercial value.

The present invention has been made in view of the above-mentioned conventional inconveniences, and its purpose is to install the door in a correct positional relationship with respect to the door frame or each component of the door, or to manufacture the door frame. Even if the door frame is not opened, the inner surface of the door is not damaged by the door frame, and the door frame is provided with the airtight packing that can maintain the airtightness with the door.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, packing grooves are provided in the vertical and horizontal directions of the door frame facing the inner surface of the door, and each of these packing grooves does not drop a hollow packing. The attached and hollow packing is a door frame with airtight packing in which elastic packing is inserted in the hollow holes at the longitudinal ends on the door end side or the top and bottom ends on the vertical and horizontal directions. .

[Action]

If the door is not properly attached to the door frame, the effect is most pronounced on the door end side of the door away from the hinge that attaches the door to the door frame.

If the door end side of the door strongly presses the hollow packing installed in the packing groove of the door frame due to mounting error, the elastic packing inserted in the hollow holes at both ends of the vertical packing at the door end side , Or the elastic packing inserted in the hollow hole of the packing at the top and bottom of the door tip side in the horizontal direction,
By reducing the compression deformation of the outer hollow packing,
It works to prevent the inner surface of the door on the door end side from coming into direct contact with the metal door frame.

〔Example〕

 An embodiment of this invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a double-sided flash type door, which is formed by bending a plate member vertically and horizontally and vertically in a door frame 2 facing a peripheral portion of an inner surface plate 1a of the door 1. The packing groove 3 is provided.

The airtightness between the door 1 and the door frame 2 when the door 1 is closed is as follows.
The hollow packing 4 mounted so as to slightly project from each packing groove 3 is kept in contact with the inner surface of the door 1.
The packing 4 is made of soft vinyl chloride, synthetic rubber, or the like, but other materials can also be used.

The hollow packing 4 installed in each packing groove 3 of the door frame 2 has a solid or hollow elastic packing 5 or 5 inserted into the hollow holes 4a or 4a at both longitudinal ends of the door tip side. ing. As the elastic packing 5, the same material as the hollow packing 4 or a different material can be used.

The position where the elastic packing 5 is inserted is not limited to the upper and lower end portions of the vertical packing 4 that comes into contact with the door tip side of the door 1, and as shown in FIGS. It may be inserted into the hollow hole 4b at the front end on the door tip side of the lateral packing 4 that abuts the upper and lower inner surfaces, or may be inserted into both of these.

Next, the operation of the device will be described when the elastic packing 5 is inserted into both ends in the vertical direction.

When the door 1 is attached with a mounting error in the cross-sectional direction as shown in FIG. 3, the inner surface of the door 1 on the door tip side is attached to the packing groove 3 on the door tip side of the door frame 2. The compressed hollow packing 4 is strongly pressed to be largely compressed. However, the longitudinal packing 4 on the door end side has a large deformation resistance against pressing force due to the elastic packings 5, 5 (see FIG. 1) inserted into the hollow holes 4a, 4a at the upper and lower ends thereof. Therefore, even when a large pressing force is applied from the door 1, the inner surface of the door 1 has elastic packing 5,
The 5 comes into contact with the inserted packing 4 and does not come into direct contact with the metal surface of the packing groove 3.

On the contrary, when the door 1 is attached with a mounting error in the vertical cross-section direction, inside the hollow holes 4a, 4a at the upper and lower ends of the vertical packing 4 on the door tip side shown in FIG. Since either one of the elastic packings 5, 5 inserted in the door 1 reduces deformation of the hollow packing 4 that is strongly pressed by the inner surface of the door 1, the inner surface of the door 1 directly contacts the metal surface of the packing groove 3. Is prevented.

Therefore, even if the door 1 is not properly attached, the packing 4 of the door frame 2 not only contacts the inner surface of the door 1 to maintain good airtightness with the door 1, but also the inner surface of the door 1. Can be reliably prevented from coming into contact with the metal surface of the packing groove 3 and being damaged. When the decorative steel plate is used for the surface plate of the door 1, this function and effect are useful for keeping the decorative steel plate in a clean state forever and increasing the commercial value.

Further, in the case of the second embodiment shown in FIG. 4, the door 1 is mounted with a mounting error in the longitudinal sectional direction as shown in FIG. 5, and the packing 4 in the lateral direction is formed on the lower inner surface of the door 1. When pressing strongly, the elastic packing 5 inserted into the door-side hollow hole 4b of the lower lateral packing 4 is
Since the large deformation of the hollow packing 4 is prevented, the inner surface of the door 1 is kept in contact with the hollow packing 4.
When the inclination of the door 1 with respect to the longitudinal cross section is opposite to the case of FIG. 5, the elastic packing 5 inserted into the hollow hole 4b at the front end of the door 4 on the upper lateral direction is different from the case described above. Do the same.

On the other hand, in the case of the second embodiment, when the door 1 is mounted with a mounting error in the cross-sectional direction, it is inserted into the door-side hollow holes 4b, 4b of the packings 4, 4 in the vertical and horizontal directions. Since the elastic packings 5, 5 that are set prevent the large deformation of the hollow packings 4, 4 that are strongly pressed by the inner surface of the door 1, the inner surface of the door 1 also contacts the hollow packings 4 in this case as well. Direct contact with the metal surface of the packing groove 3 is prevented.

[Effect of device]

In this invention, a hollow packing is installed in the packing grooves provided in the vertical and horizontal directions of the door frame, and both longitudinal ends of the packing at the door end side or inside the hollow holes at the door end side in the vertical and horizontal directions. Since the elastic packing is inserted into the door frame, the door may not be correctly attached to the door frame due to manufacturing errors or mounting errors, and the vertical packing on the door tip side of the door frame or the vertical and horizontal packing may depend on the door. When strongly pressed, the amount of deformation of the hollow packing is reduced by the action of the elastic packing inserted in the hollow holes at the upper and lower ends of these packings, or the elastic packing inserted in the hollow holes at the top and bottom door tips. It is possible to reliably prevent the inner surface of the door from coming into contact with the metal surface of the packing groove of the door frame and being damaged.

In addition, the elastic packing inserted in the hollow hole of the hollow packing not only prevents the inner surface of the door from directly contacting the metal surface of the door frame, but also makes the inner surface of the door into a hollow shape that is installed in the packing groove. Since the packing is always in contact with the packing, the airtightness between the door frame and the door can be maintained in a good state even when the door is not attached in the correct positional relationship.
