BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an obturator used for an insertion portion of a gas hose pulled out from the inside of a cabinet such as a sink.

[0002]

2. Description of the Related Art Generally, a gas tap installed in a kitchen is
As shown in FIG. 11, it is often arranged on the wall above the sink or on the upper part of the cabinet 4 of the sink in consideration of gas connection to the rice cooker. Even when using floor-standing type equipment such as a fan heater 6, this gas plug 5
There is a case where the gas hose 2 is connected from No. 1, but in this case, the end portion of the gas hose 2 is pulled up and connected to the height position of the gas plug 51.

At this time, the gas hose 2 pulled up
Is above the sink on top of cabinet 4 or cabinet 4
Crawling the front surface of the gas hinders cooking work, and depending on the case, there is a risk that the gas hose 2 may get caught in the floor and the floor-standing type appliance may fall over. In order to solve such a problem, as shown in FIG. 11, a spare gas plug 50 is arranged inside the cabinet, and the gas hose 2 is formed on the bottom plate 41 in front of the panel 42 of the cabinet 4. There is one that can be pulled out through the through hole 40.

In this structure, the gas hose 2 extending from the gas fan heater 6 is connected to the gas plug 50 inside the cabinet 4 through the through hole 40, so that the gas hose 2 interferes with cooking work. do not become.
Generally, a hose connector which is easy to connect is used for connecting the gas hose 2 and the gas plug 50, and a socket 3 which is a female member of the hose connector is attached to an end of the gas hose 2. It is composed. Since this socket 3 usually has a diameter larger than that of the gas hose 2, a through hole 40 through which the gas hose 2 equipped with the socket 3 can be inserted is formed in the bottom plate 41, the wall plate or the like of the cabinet 4.
In the case of providing the gap, a gap G is created between the through hole 40 and the gas hose 2. There is a problem that harmful insects such as cockroaches and mice may enter the cabinet 4 through the slight gap G, or the stored articles may fall below the bottom plate 41. In order to solve such a problem or inconvenience, as shown in FIG. 12, an obturator 1 for obstructing a gap G between the gas hose 2 and the through hole 40 is used.

DISCLOSURE OF THE INVENTION According to the present invention, "a flexible gas hose having a gas connector at its tip is inserted into a through hole provided in a wall of a cabinet, and an outer peripheral gap of the insertion part of the gas hose is provided. It is an object of the present invention to allow the gas hose to be inserted thereinto and to surely put the insertion portion of the gas hose into a closed state.

[0007]

[Means for Solving the Problems] Item 1 The technical means of the present invention for solving the above-mentioned problems is that "an obturator is an annular member for adhering or adhering to the constituent wall around the through hole. And a disc-shaped lid member made of an elastic material that is continuously provided on the inner peripheral side of the attachment member. The lid member has an insertion hole having a diameter substantially the same as the outer diameter of the gas hose. Then, a notch having a predetermined length continuous to the insertion hole is formed, and a plug member capable of closing the insertion hole of the lid member is continuously provided to the attachment member.

The above technical means operate as follows. According to the above means, the obturator is fixed to the constituent wall by attaching or adhering the attachment member to the peripheral edge of the through hole. Further, since the lid member is made of an elastic material, and the insertion hole is formed with a notch having a predetermined length set in accordance with the size of the gas connecting tool so as to be continuous with the insertion hole, it is better than the gas hose. When pushing in the thick gas connector part, the insertion hole is enlarged according to this cut length, and is somewhat larger than the outer diameter of the gas hose such as the connector to the gas plug provided at the tip of the gas hose. A portion having a diameter can also be inserted. Further, after the large-diameter portion is inserted, the lid member is automatically returned to the disc shape before being deformed by its own elastic force. As a result, the edge portion of the cut is brought into a close contact state or a state similar thereto. Since the insertion hole through which the gas hose is inserted is set to have substantially the same diameter as the outer diameter of the gas hose, when the gas hose is inserted into the insertion hole, the peripheral edge of the insertion hole and the outer periphery of the gas hose are There is almost no gap between them.

[0009] When the gas hose is not inserted, the plug member is attached to the insertion hole by "a plug member that can close the insertion hole of the lid member is connected to the attachment member". Since it is possible to close the through hole, it is possible to always close the through hole.

* 2 In addition, "The obturator is an annular mounting member for adhering or adhering to the constituent wall around the through hole, and an elastic material continuously provided on the inner peripheral side of the mounting member. Made of a disk-shaped lid member made of a gas, the lid member is formed with an insertion hole having a diameter substantially the same as the outer diameter of the gas hose, and a notch having a predetermined length continuous to the insertion hole, In the case where an auxiliary lid that is removably fitted into the upper end opening of the cylindrical body is continuously provided to the attachment member, '' in the same manner as described above, the through hole can be closed when the gas hose is not inserted, and the auxiliary Since the lid is configured to be fitted into the upper end opening of the cylindrical body that is the attachment member, the through hole can be firmly closed.

* 3 In paragraphs 1 and 2, "the mounting member is formed so as to extend outward from the outer peripheral wall of the cylindrical body and the cylindrical body which is in contact with the lid member and can be inserted into the through hole. The circular flange is formed by fixing the position of the obturator by fitting the cylindrical body with the through hole, and by attaching the flange to the constituent wall around the through hole by the flange formed in a manner to project outward. Since it is attached, it is stably arranged in the through hole without shifting in the horizontal direction.

[0012] * In the item 4 and 3, "the double-sided adhesive tape is adhered to the lower surface of the flange", so that the obturator uses the double-sided adhesive tape to form a wall around the through hole. Since it is adhesively fixed to, the installation work is easy.

[0013]

The present invention, having the above-mentioned structure, has the following unique effects. Since the insertion hole formed in the lid member can insert a portion having a diameter larger than the outer circumference of the gas hose, the obturator remains in the through hole provided in the cabinet wall. Thus, it is possible to insert a gas hose having a hose connector at its tip without removing the obturator from the through hole. In addition, after the gas hose is inserted, the edge portion of the cut is automatically restored by the elastic force thereof to be in a close contact state or a state close to this, and there is no gap between the insertion hole and the gas hose. Therefore, the through hole is almost completely closed by this obturator, and the invasion of harmful insects into the cabinet is prevented. Since the plug member that can close the insertion hole of the lid member is continuously provided to the attachment member, the through hole can be always closed even when the gas hose is not inserted. Further, in the case where the auxiliary lid that is removably fitted into the upper end opening of the cylindrical body is continuously provided to the attachment member, the through hole can be firmly closed when the gas hose is not inserted. Further, in addition to the above effects, in the third item, the through holes are stably arranged. In item 4, the mounting work is easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the embodiments of the present invention described above will be described in detail with reference to the drawings. Reference Example First, a reference example of the present invention will be described. An example of the obturator 1 of the present reference example is shown in FIGS. 1 and 2. This obturator 1
Has a larger diameter than the through hole 40 for inserting the gas hose 2 formed in the bottom plate 41 of the cabinet 4, and
A disk-shaped lid member 12 in which an insertion hole 10 of the gas hose 2 is formed in the center thereof, and a cylindrical body which is continuously provided so as to circumscribe the lid member 12 and is inserted in the peripheral edge of the through hole 40 in an inscribed state. It is composed of 15 and.

The lid member 12 has an insertion hole 10 having a diameter D which is substantially the same as the outer diameter H of the gas hose to be inserted.
And a cross-shaped notch 13, 1 provided so as to be continuous with the insertion hole 10 and intersect at the center of the lid member 12.
3 are provided, and thereby four elastically deformable flexible pieces 14, 14 are formed.

An annular flange 11 is formed on the upper edge of the cylindrical body 15 so as to extend outwardly over the entire circumference thereof. A double-sided adhesive tape 8 for adhering the obturator 1 to the bottom plate 41 around the through hole 40 is arranged on the lower surface of the flange 11, and the lower surface is covered with release paper. Also,
Since the outer diameter L of the cylindrical body 15 is set so as to be inscribed in the peripheral edge of the through hole 40, the obturator 1 has the through hole 4
It is fitted with 0 and fixed to the bottom plate 41. The obturator 1 of this example is made of natural rubber (NBS).

* Actual use of obturator When the obturator 1 of this example is arranged in the through hole 40 provided in the bottom plate 41 of the cabinet 4, and the gas hose 2 having the socket 3 is inserted through the obturator 1. The actual use of this obturator will be described with reference to FIG. Obturator 1 of this example
In addition to the adhesion with the double-sided adhesive tape 8, the cylindrical body 1
Since 5 is fitted in the through hole 40, the obturator 1
Has greater resistance to horizontal movement.

When the gas hose 2 having the socket 3 is inserted into the obturator 1, the socket 3 is moved upward from the bottom of the bottom plate 41 to the center of the lid member 12 as shown in FIG. Push in the direction of the arrow). At this time,
Although the diameter M of the socket 3 is larger than the diameter D of the insertion hole 10, the flexible pieces 14, 14 separated from each other at the peripheral edge of the insertion hole 10 are pressed by the socket 3 and elastically deformed upward. It As a result, the lid member 12 is pushed open from the center along the cross shape of the notches 13 and 13, and the insertion hole 10 is expanded, so that the socket 3
Is inserted without great resistance.

After the socket 3 is inserted,
Since the gas hose 2 is inserted into the insertion hole 10 which is set so as to substantially match the outer diameter M of the gas hose 2, the flexible pieces 14 and 14 are in a state before being elastically deformed by their elastic force. Automatically restored, the edges of the notches 13 and 13 come into close contact with each other, and as shown in FIG.
The through hole 40 is closed while the gas hose 2 is inserted.

When the gas hose 2 is removed, as in the case of inserting the gas hose 2, the gas hose 2 is pulled from below the bottom plate 41 to insert the gas hose 2, and then the socket 3 is attached to the lid member 12. The flexible pieces 14, 14 are elastically deformed by pushing downward so that the insertion holes 10
Can be easily removed by enlarging. Further, after the gas hose 2 is pulled out from the insertion hole 10, the flexible pieces 14, 14 are returned to their original state by their own elastic force. From this, the obturator 1 of this example has the bottom plate 4
It is possible to easily insert the gas hose 2 having the socket 3 at the tip end thereof in a state of being fixedly installed in the first through hole 40, and to close the through hole 40 in the state where the gas hose 2 is inserted.

* Others In the above-mentioned example, the insertion hole 10 is formed in the center of the lid member 12 so as to be concentric therewith. However, as shown in FIG. It may be formed at the eccentric position. In the example of FIG. 6, the gas hose 10 inserted through the insertion hole 10 at the eccentric position is
Since the two flexible pieces 14, 14 are held by their edges including a portion close to the connecting portion with the flange 11, the insertion hole 10 is provided in the center of the lid member 12 as in the above-described example. The force for holding the gas hose 2 is larger than that in the case of being held by the tips of the four flexible pieces 14, 14.
Therefore, the gas hose 2 can be kept in close contact even when the elastic material forming the flexible pieces 14, 14 is set to have a small thickness.

Further, the notches 13 and 13 do not have to be formed in a cross shape which intersects at the center of the lid member 12 as shown in the above-mentioned example and FIG. 6, and they are continuous with the insertion hole 10 and the socket of the gas hose 2. As long as the previous insertion hole 10 can be enlarged so that 3 can be inserted, the notch 13 may be formed in the lid member 12 by one or a large number, and its forming length. The position of the sheath is not limited.

Next, examples of the present invention will be described.
