Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an airtight door packing which is attached to a door stop of an apartment house, a detached house or the like, and elastically contacts the left and right ends of the door to seal between the door stop and the door.

[0002]

[Prior art]

 Conventionally, an airtight door packing 30 that is attached to a door stop 10 shown in FIGS. 1 to 3 of an apartment house, a detached house, etc. and elastically contacts the left and right ends of the door 20 to seal between the door stop 10 and the door 20. As the above, the ones shown in FIGS. 4 to 7 are used. What is shown in FIGS. 4 and 6 is called a hollow type, and a hollow seal portion 32 having a hollow cross section is joined to one end of a base portion 31 having a plurality of claws on its side surface. The one shown in FIGS. 5 and 7 is called a vent type, and a seal portion 33 having a V-shaped cross section is coupled to one end of a base portion 31 having a plurality of claws on its side surface. Reference numeral 21 is a knob that is gripped when the door 20 is opened and closed, and 22 is a hinge that rotatably attaches the door 20 to the door stop 10.

The manner of receiving the compression of the seal portions 32 and 33 from the door 20 when the door 20 is closed is different as shown below. That is, as shown in FIG. 2, the side to which the hinge 22 is attached is compressed in the direction S parallel to the surface of the door 20. As shown in FIG. 3, the side to which the knob 21 is attached is compressed in the direction T perpendicular to the surface of the door 20. However, when the side to which the hinge 22 is attached is compressed, the seal portions 32 and 33 may be caught in the gap between the end face of the door 20 and the door stop 10 as shown in FIG. It may be necessary to increase the force for closing the door, and in extreme cases, the resistance may be large and the door 20 may not close. If the height (or length) of the airtight door packing 30 is reduced so that the seal portions 32 and 33 are not caught in the gap between the end surface of the door 20 and the door stop, the clearance when the door 20 is installed is reduced. However, there is a problem in that the sufficient sealing performance may not be exhibited due to the above problems.

[0004]

The problem to be solved is that in the conventional airtight door packing 30 described above, the seal portions 32 and 33 on the side to which the hinge 22 is attached are compressed so that the end face of the door 20 and the door stop 10 are closed. It is necessary to increase the force to close the door 20 by being caught in the gap between the and, or in extreme cases, the resistance is large and the door 20 will not close.

[0005]

[Means for Solving the Problems]

 This will be described with reference to FIGS. 1 to 3 and 8 to 10. The present invention is an airtight door packing 30 which is attached to a door stop 10 and elastically contacts the left and right ends of the door 20 to seal between the door stop 10 and the door 20. On the other hand, a first bending point 41 that bends convexly toward the door stop 10 is provided in the vicinity of the root of the hollow seal portion 40 having a concave "<" shape on the door stop 10 side. A second bending point 42 that bends concavely toward the door stop 10 is provided at an intermediate point between the point 41 and the tip of the sealing portion 40, and a point slightly deviated from the second bending point 42 to the tip of the sealing portion 40. A third bending point 43 is provided at a point on the opposite side of the door stop 10 side, and is bent concavely toward the door stop 10.

[0006]

【Example】

An embodiment will be described. 10 is a rectangular frame-shaped door stopper when viewed from the front, 20 is a door that is attached to the door stopper 10 via hinges 22 and 22 so as to be openable and closable, and 30 is a door stopper that is attached to the door stopper 10. It is an airtight door packing that elastically contacts the left and right ends of the door and seals the space between the door stop 10 and the door 20. The hollow seal portion 40 having the shape of "<" is connected, and the details are as follows. That is, the seal portion 40 is provided with three bending points. First, at the first bending point 41, the vicinity of the base of the door stop 10 side is convex toward the door contact 10, and at the second bending point 42. The midpoint between the first bending point 41 and the tip of the sealing portion 40 is concave toward the door stop 10, and at the last third bending point 43, slightly from the second bending point 42 to the tip of the sealing portion 40. The points on the side opposite to the door stop 10 side of the approached point are concavely bent toward the door stop 10 respectively. Further, there is a relationship of L ₁ <L ₂ <L ₃ between the bottom surface of the base 31 and the lengths L ₁ , L ₂ and L ₃ of the respective bending points 41, 42 and 43. It should be noted that it is desirable to make a notch at each of the bending points 41, 42 and 43 in order to facilitate bending.

To explain the operation, when the door 20 is closed, the side of the seal portion 40 on which the knob 21 is attached is compressed vertically to the surface of the door 20, and the side on which the hinge 22 is attached is of the door 20. It is compressed in the direction parallel to the plane, and the degree of bending is increased at the bending points 41, 42, 43, and it is deformed. In particular, when the side where the hinge 22 is attached is compressed, the seal portion 40 is deformed so as to be folded as shown in FIG. 10, so that it is not caught in the gap between the end surface of the door 20 and the door stop 10. Moreover, since the notch and the like are provided, it is easily bent and the door closing force becomes small. Further, even if there is a problem of a clearance when the door 20 is installed, the door 20 can flexibly follow, so that a wide sealing range can be obtained and sufficient sealing performance can be exhibited. In addition, the fatigue of the seal is less than that of the conventional vent type, ensuring long-term sealing performance.

[0008]

[Effect of device]

 Since the present invention is configured as described above, when the door 20 is closed, the seal portion 40 is deformed without any trouble on both the side where the knob 21 is attached and the side where the hinge 22 is attached. In particular, the side to which the hinge 22 is attached is deformed such that the seal portion 40 is folded when compressed, so that it is not caught in the gap between the end face of the door 20 and the door stop 10, and a notch or the like is provided. It is easy to bend, has a small door closing force, and exhibits sufficient sealing performance.
