Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door sealing device.
[0002]
[Prior art]
As this type of conventional sealing device, the one shown in FIG. 6 is known. In this sealing device, a seal frame 31 is attached to the inner surface of a door frame 30, and a seal support 34 is incorporated in a guide groove 33 that opens on a surface facing the door 32 of the seal frame 31. A side seal member 35 is attached to the outer surface, and each side seal member 35 is brought into contact with the inner surface of the guide groove 33 to seal between the seal support 34 and the inner surface of the guide groove 33.
[0003]
A tubular seal member 36 is attached to the surface of the seal support 34 that faces the door 32, and the seal member 36 is brought into contact with the inner surface of the door 32 to seal between the seal member 36 and the door 32.
[0004]
In the sealing device, the tubular sealing member 36 often does not contact the door 32 uniformly over the entire length due to the assembly accuracy of the door frame 30, the mounting accuracy of the seal frame 31, the warp of the door 32, or the like. Therefore, a plurality of adjustment screws 37 are screwed into the indoor surface of the seal support 34, the adjustment screws 37 are rotatably supported by the seal frame 31, and the seal support 34 is attached to the door 32 by the rotation of the adjustment screws 37. The contact pressure of the seal member 36 with respect to the door 32 can be adjusted.
[0005]
[Problems to be solved by the invention]
By the way, in the said conventional sealing device, when there is a part which covers the indoor surface of the seal frame 31 in the door frame 30, the adjustment screw 37 cannot be rotated. The L-shaped decorative frame 38 is detachably attached to cover the seal frame 31.
[0006]
For this reason, it is necessary to remove the decorative frame 38 every time the contact pressure of the sealing member 36 occurs, and there is a disadvantage that adjustment is very troublesome.
[0007]
An object of the present invention is to provide a door sealing device that can easily adjust the contact pressure of a sealing member that seals between doors by contact with the door.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, in a door sealing device that opens and closes an entrance / exit of a door frame, the upper frame of the door frame and the inner surfaces of a pair of saddle frames are opposed to the inner peripheral portion of the door. A seal frame is attached, and a seal support that is formed in the seal frame and extends in the length direction of the seal frame and opens in the surface facing the door is incorporated into the guide groove that is long in the length direction of the guide groove. Side seal members that contact the inner surface of the guide groove are attached to the inner and outer surfaces of the seal support, and two seal members that extend in the length direction of the seal support are provided on the surface of the seal support that faces the door. Of the two seal members, the inner seal member is provided with an outwardly inclined lip whose tip is elastically contacted with the inner surface of the door, and the outer seal member is provided with a tip on the indoor surface side of the outwardly inclined lip. Makes elastic contact A slanting lip is formed, and a plurality of screw holes penetrating the indoor and outer surfaces of the seal support member are provided between the two seal members in the seal support member. A configuration is adopted in which the tip of the adjustment screw that is rotated from between the seal members is rotatably supported by a fixed seat attached in the seal frame.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0010]
As shown in FIG. 1, the door 3 covering the doorway 2 of the door frame 1 is supported so as to be openable and closable around a hinge 4 attached to one side.
[0011]
The upper frame 5 and the pair of eaves frames 6 of the door frame 1 are provided with a bulging portion 7 that protrudes inward and faces the outer peripheral portion of the indoor surface of the door 3.
[0012]
As shown in FIGS. 2 and 3, the bulging portion 7 includes a first surface 8 and a second surface 9 that are different in distance from the indoor surface of the door 3, and a frame provided between both surfaces 8 and 9. The seal frame 11 is fixed to the frame mounting surface 10 by tightening mounting screws 12.
[0013]
The seal frame 11 extends long in the longitudinal direction of the corresponding frame. The seal frame 11 has a guide groove 13 that opens on the outdoor surface side, and a seal support 14 that extends in the longitudinal direction of the seal frame 11 is incorporated between the guide grooves 13.
[0014]
Side seal members 15 are attached to the inner surface and the outer surface of the seal support 14, and the seal members 15 are in contact with the inner surface of the guide groove 13 to seal between them.
[0015]
Further, two seal grooves 16 extending in the length direction of the seal support 14 are formed on the outdoor surface of the seal support 14 facing the door 3, and the base of the inner seal member 17 is formed in the inner seal groove 16. Has been inserted. Further, the base of the outer seal member 18 is inserted into the outer seal groove 16.
[0016]
The inner seal member 17 is thicker than the outer seal member 18, and an outwardly inclined lip 19 is provided on the inner seal member 17. When the door 3 is closed, the outward inclined lip 19 is brought into elastic contact with the outer peripheral portion of the inner surface of the door 3 to seal between the doors.
[0017]
The outer seal member 18 is provided with an inwardly inclined lip 20 whose tip is in elastic contact with the indoor surface side of the outwardly inclined lip 19.
[0018]
A plurality of screw holes 21 are formed in the seal support 14 in the length direction of the seal support 14 between the two seal grooves 16 so as to penetrate the indoor and outer surfaces of the seal support 14. An adjusting screw 22 is screwed to 21.
[0019]
As shown in FIG. 4, the adjustment screw 22 is provided with a square hole 23 on one end surface located between the inner seal member 17 and the outer seal member 18, and the other end is rotatably supported by a fixed seat 24. .
[0020]
As shown in FIGS. 2 and 3, the fixed seat 24 is prevented from moving toward the opening side of the guide groove 13 by a pair of ribs 25 provided on the inner surface of the guide groove 13. The fixing seat 24 is fixed by tightening a mounting screw 26 screwed from the outer surface side of the seal frame 11.
[0021]
Now, when the door 3 is closed, the outward inclined lip 19 of the inner seal member 17 is pushed by the door 3 and deformed to the indoor side. Due to the elastic deformation of the outward inclined lip 19 of the member 17, the distal end portion of the inward inclined lip 20 of the outer seal member 18 is in strong elastic contact with the outward inclined lip 19.
[0022]
For this reason, the outward inclined lip 19 comes into contact with the door 3 by its own restoring elasticity and the elasticity of the inwardly inclined lip 20, and seals the door 3 very well.
[0023]
Here, when the door 3 is warped or the door frame 1 is distorted, the contact pressure of the inner seal member 17 to the door 3 and the contact pressure of the inner seal member 17 and the outer seal member 18 become non-uniform, The sealing performance is lowered, and the contact pressure needs to be adjusted.
[0024]
When adjusting the contact pressure, as shown in FIG. 5, the door 3 is opened, and a square wrench A is inserted between the inner seal member 17 and the outer seal member 18 to engage with the square hole 23 of the adjustment screw 22. The seal support 14 is moved in the outdoor direction by the rotation of the adjusting screw 22.
[0025]
【The invention's effect】
As described above, in the present invention, since the adjusting screw can be rotated between the inner seal member and the outer seal member, the contact pressure of the inner seal member on the door can be adjusted very easily.
[0026]
In addition, the outwardly inclined lip of the inner seal member is pressed against the door by its own elasticity and the elasticity of the inwardly inclined lip of the outer seal member, so compared with the case where a single seal member is pressed against the door. Good sealing performance can be exhibited.
