Description

[Detailed description of the invention] The present invention is a door frame of an opening/closing door that allows the position of the bead member that ensures airtightness between the opening/closing door such as an entrance door and the doorstop to be higher than the standard position if necessary. It's about structure.

In general, cold air, snow, dust, etc. can enter the frame of this type of door through the gap between the door stop and the door, for example in cold regions, snowy regions, or regions with strong seasonal winds. In order to prevent this, an airtight bead member is installed on the doorstop side of the doorstop.
Some devices have a bead member that elastically presses against the opening/closing door when the door is closed, thereby improving airtightness.
However, door frames are not particularly susceptible to infiltration of powdered snow or dust due to the rising wind, and especially in the case of the bottom frame, bead members are susceptible to deformation due to foot traffic. Therefore, in some cases, it is necessary to further improve airtightness on the door frame side, and countermeasures for this purpose are desired.

The present invention was devised to eliminate these drawbacks in view of the above-mentioned actual situation, and is suitable for use in cold regions,
In cases where airtightness is particularly required, such as in areas with heavy snowfall or strong seasonal winds, the conventional lower frame can be used as a standard lower frame, and by providing auxiliary members to this standard lower frame, the bead member position can be adjusted. The purpose is to provide a door frame structure for an opening/closing door that can significantly improve airtightness by positioning the door at a higher position than the standard one. A standard door frame is formed to which an airtight bead member can be fixed to the doorstop side vertical side of the doorstop part, and an airtight bead member is attached above the doorstop part of the standard door frame. The present invention is characterized in that an auxiliary member is provided so that the standard lower frame can be formed on the door frame with the bead member at a higher position than the standard lower frame.

Next, the present invention will be explained in more detail based on an embodiment shown in the drawings. In the drawing, 1 is an opening/closing door attached to the entrance via a hinge, 2 is a handle, 3 is an upper frame, 4 is a lower frame, and 5 is a vertical frame, all of which are constructed in the conventional manner.

The lower frame 4, like the upper frame 3 and the vertical frame 5, has an opening/closing door 1.
It is formed into a stepped shape by a smooth part 4a facing the edge of the door stop 4a and a door stop part 4b that protrudes from the smooth part 4a.
A fastening groove 4d to which the bead material 6 can be detachably fastened is formed in c. As will be described later, in the standard case, the opening/closing door 1 is placed in the conventional state with the bead material 6 fixed in the fixing groove 4d as shown in FIG.
The gap A between the lower frame 4 and the lower frame 4 is sealed to maintain airtightness.

Reference numeral 7 denotes an auxiliary member, and the auxiliary member 7 is attached to the upper side of the door stop portion 4b, and a bead material 6 is detachably attached to the vertical side 7a of the auxiliary member 7 on the door stop side (outdoor side). A fastening groove 7b that can be fastened is formed, and the lower end edge of the vertical side 7a has a fastening piece 7c that fits into the fastening groove 4d on the lower frame 4 side.
and a protruding piece 7d protruding toward the opening/closing door 1 side are integrally formed into a substantially inverted T-shape. Also, the vertical side 7e of the auxiliary member 7 on the side opposite to the doorstop side (indoor side)
hangs downward along the indoor vertical side 4e of the door stop portion 4b, and on the inside of the middle part, a locking piece 7c of the auxiliary member 7 is inserted into the lower frame side fastening groove 4d.
The door stop part 4 corresponds to the installation state in which the
A locking piece 7f that abuts and locks on the upper end surface b is protruded, and a V-shaped groove 7g is carved on the surface side corresponding to the position of the locking piece 7f. Furthermore, the lower end edge of the indoor side vertical side 7e is shaped like an L-shape toward the outdoor side so as to come into surface contact from the outside with a substantially L-shaped part bent at the lower end edge of the indoor side vertical side 4e of the door stop part 4b. It is formed into a bend.

In the embodiment of the present invention constructed as described above, when assembling the opening/closing door 1, there is usually a hole on the bottom frame 4 on the doorstop side of the doorstop part 4b, as in the standard case shown in FIG. The bead member 6 may be fitted and fixed into the provided fastening groove 4d, and in this case, the gap A between the opening/closing door 1 and the door stop portion 4b of the lower frame 4 is
As in the case of the upper frame 3 and the left and right vertical frames 5, the bead member 6 elastically presses against the edge of the opening/closing door 1 to seal it, ensuring airtightness in the standard state. That will happen.

On the other hand, if the airtightness of the lower frame 4 side needs to be better than the standard case, such as in a cold region, in the present invention, the auxiliary member 7 is attached above the lower frame 4, and the bead member 6 may be positioned higher than the standard one. In this embodiment, if the auxiliary member 7 is installed together with the assembly work of the lower frame 4, the attachment of the auxiliary member 7 is performed as shown in FIG.
This can be done extremely easily by slidingly inserting the auxiliary member 7 from one end.
In this case, on the doorstop (outdoor side) side of the auxiliary member 7, the locking piece 7c fits into and locks in the fastening groove 4d on the lower frame 4 side, and on the indoor side, the locking piece 7c of the auxiliary member 7 on the indoor side vertical side 7e is locked.
Since the lower end is locked to the lower end edge of the corresponding lower frame side vertical side 4e, once these are assembled integrally, the auxiliary member 7 can be lowered without using the screw 8 as described later. Although it can be fixed without any possibility of it being pulled out from the frame 4, it can be fixed even more securely by fixing with screws 8 if necessary. When the auxiliary member 7 with the bead member 6 is attached to the standard lower frame 4 in this way, the auxiliary member 7 and the doorstop part 4b on the lower frame 4 side are integrated as shown in FIG. It acts on the opening/closing door 1 as a tall door stop, and therefore the bead member 6 is located at a higher position than in the standard case to provide an airtight effect. Therefore, for example, if you use this in snowy areas or cold areas,
Most of the snow and cold air that tries to enter the interior of the room due to the rising wind is blocked by the gap A, which is longer in the vertical direction than the standard one. , it is possible to ensure excellent airtightness. Moreover, in order to ensure this excellent airtightness, it is only necessary to simply attach the auxiliary member 7 to the standard lower frame 4, and the standard lower frame 4 is common in all cases. Since there is no need to form and prepare a specially shaped bottom frame for use in cold regions, parts management is not only significantly simplified, but also quick response during assembly and construction is possible. will be possible.

Moreover, in this embodiment, the door stop side vertical side 7a of the auxiliary member 7 is a locking side 7 formed at the lower end edge of the vertical side 7a.
Since c is adapted to be locked in the bead member fixing groove 4d of the lower frame 4, the auxiliary member 7 can be firmly attached by effectively utilizing the lower frame 4 as it is, and
Another advantage is that the mounting position is accurate.

Further, due to the protruding side 7d that faces the locking side 7c and protrudes toward the opening/closing door 1 side, the gap A is formed between the protruding side 7d and the bead member 6 above the protruding side 7d.
Since the upper and lower two stages of sealing and airtight action are performed, snow, cold air, etc. are almost prevented from entering by the lower protrusion 7d, and then the upper bead member 6 This has the advantage that almost perfect airtightness can be maintained.

In addition, if you want to attach it to the existing lower frame 4, cut the auxiliary member 7 along the approximately V-shaped groove 7g as shown in FIG. It suffices to place the door stop 4b from above while it is locked on the side and fix it via the screws 8. Even in this case, the structure is such that the locking side 7c locks in the locking groove 4d. Therefore, construction is easy and there is no possibility of installation errors.

It should be noted that the present invention is of course not limited to the above-mentioned embodiment, and if necessary, it can be attached not only to the lower frame but also to the vertical frame and the upper frame.
Further, the structure of the auxiliary member may be such that it can be simply attached and fixed with screws, etc., but as shown in FIG. portions 9c and 9d are provided, and both the locking portions 9c and 9d forcefully push the auxiliary member 9 from the upper side of the lower frame 4 into the locking groove 4d and the locking groove 4f of the lower frame 4. By locking each member, the shape of the auxiliary member 9 can be made smaller than that of the above-mentioned embodiment, which improves economic efficiency.
When attaching to the existing lower frame 4, depending on the position of the locking groove 4f, there is an advantage that the trouble of cutting the auxiliary member 9 at the V-shaped groove 9g position can be omitted, which is extremely convenient. Further, the auxiliary member may be made of a rubbery elastic material formed integrally with the bead member.

In summary, the present invention forms a standard door frame in which an airtight bead member can be fixed to the door stop side vertical edge of the door stop part protruding from the door frame, and the door stop of the standard door frame. An auxiliary member to which an airtight bead member is attached is provided above the door frame, allowing the standard lower frame to be formed into a door frame with the bead member at a higher position than the standard one. In cases where airtightness is particularly required for areas such as ground, simply attach an auxiliary member to the door stop of the standard bottom frame.
As a result of being able to create a tall doorstop with the bead member positioned higher than the standard one, it is possible to prevent snow, etc. blown up by the opening/closing door from entering the room. It can definitely be prevented,
It can have excellent airtightness. Moreover, in this case, if auxiliary parts are prepared, the standard bottom frame can be used effectively as is, so there is no need to prepare a specially shaped bottom frame each time, which simplifies parts management. However, it can be made advantageous in terms of price.
