Description

[Detailed description of the invention] This invention is a fitting that is interposed between an aluminum profile door or door stile and the door frame and door frame that surround them to maintain airtightness and watertightness between the stile and the frame. This invention was devised for the purpose of obtaining a tight material that has good airtightness and watertightness and does not require a large force to close doors, etc.

FIG. 1 is a cross-sectional view schematically showing the state in which such a tight material is used for the door contact part, in which a door 2 is pivotally attached to a wall 1 by a shaft 3, and the wall 1 is connected to another wall 4. An opening 5 formed in between is opened and closed by a door 2. Vertical tight members 6, 6 are attached to the edges of the walls 1, 4, and when the door 2 is closed, the edge of the door first hits the tight member 6, and when the door 2 is further pressed strongly against this, the tight member 6 closes. As the door is elastically deformed and the elastic force against the door increases, the pin of the door that goes in and out engages with the socket in the wall 4, closing the door and preventing wind and rain from entering from outside. The tight material 6 may be attached to the door 2 instead of the wall.

Conventionally, the tight material used in this manner has the cross-sectional shape shown in FIG. 2.

That is, the conventional tight material is made in the form of a string from a flexible elastic material such as sponge rubber, and is attached to both side edges of the plate-like cover 9 at the rear (in this specification, front and back refers to the top of the drawing, and the bottom to the bottom). A locking portion 8 is formed on the edge of the groove 7 having a narrow opening formed in the stile or frame of the fittings by being elastically deformed and pushed into the groove 7, and is locked on the edge of the groove 7. The rear parts of 8 and 8 are connected by a plate-like connecting part 11 to form a cover part 9, a locking part 8, 8, and a connecting part 1.
1, and a fin-like tight piece 10 was made to protrude diagonally forward from one end of the covering part 9 toward the other end.

When this conventional tight material is attached to a wall 4 and the door 2 is closed as shown in Fig. 1, the tight piece 10 first hits the door 2, and when the door is further pushed, the chain line shown in Fig. 2 As shown in , the tip of the tight piece 10 is crimped to the end of the covering part 9, and the tight piece 10, the covering part 9, and the locking part 8 are elastically deformed, and the door further penetrates into the wall 4, and the pin of the door is pushed into the wall. comes to engage with the socket.

However, with this conventional tight material, tight piece 1
0 comes into contact with the locking part 8 as shown by the chain line in Figure 2, so when the door is closed, the thick locking part 8 is pressurized and elastically deformed, and the pin and the receiving part are pressed together. In order to engage the opening, the door had to be pushed with strong force, making it impossible to operate the door lightly. In an attempt to make this operation easier, if the position of the socket is changed so that the pin of the door engages with the socket on the wall before the locking part 8 is significantly elastically deformed, the force pressing the tight piece 10 becomes weaker. The airtightness and watertightness, that is, the tightness will be weakened.

This invention provides a tight material that can achieve both the above-mentioned operability and tightness.

FIG. 3 shows the cross-sectional shape of the first embodiment of the tight material of this invention. The same reference numerals are used to refer to the same parts as in the past.The tight material is made of a flexible elastic material in the form of a hollow string, and the locking part 8 is locked in the groove 7 to attach it to the fitting. Installed. A plate-shaped covering part 9 is connected to the front surface of the locking part 8 to form a hollow part 13 between it and a connecting part 11 that connects the locking parts 8 on both side edges. A tight piece 12 is formed to protrude obliquely from one end toward the other end. The cover part 9 is slightly bent and slightly protrudes forward, and the tight piece 12 is the same as the conventional tight piece 10 in FIG.
The tip is made shorter than the locking portion 8, so that when the door is pressed when the door is closed, the tip thereof hits the covering portion 9 in front of the hollow portion 13 inside the locking portion 8.

In this way, connect the tip of the tight piece 12 to the hollow part 13.
When closing the door, the tip of the tight piece 12 is first pressed against the cover 9 as shown in FIG. 4, and when the door is further pushed, the fifth As shown in the figure, the cover 9 is bent, the door is pushed in, and the pin of the door is locked in the socket. Since the covering part 9 protrudes forward,
There is little resistance to such bending deformation, and it can be deformed with a light force.

FIG. 6 shows a second embodiment of the tight material of this invention. Since the previous example is attached to one groove 7, the locking parts 8, 8 on both sides are connected to the connecting part 11, and both locking parts are brought close together. In contrast, two parallel grooves 15, 15 are formed independently so that they can be attached to fittings, and there are separate long and continuous locks on both sides of the covering part 9. Sections 8, 8 are provided to be elastically engaged with the grooves 15, 15, respectively. The two locking parts 8, 8 are located in the grooves 15, 1.
Since it is fixed by 5, the connection part 1 is fixed as in the previous example.
There is no need to provide 1. A space 13a exists behind the covering part 9. As in the previous example, when the tight piece 12 is bent, the tip thereof does not reach the locking part 8, so that a large force is not required when closing the door, and airtightness and watertightness are improved.

In this way, if the tight material of this invention is used, when the door is pushed, the cover part 9 is only bent, and the thick locking part 8 is not compressed and elastically deformed as in the conventional case, so the door can be closed. Operation can be performed with light force. In addition, since the locking part 8 is not deformed, the engagement between the tight material and the fittings will not loosen and the tight material will not move within the groove 7 or the groove 15, and the fitting of the tight material to the fittings will be ensured, ensuring tightness and ease of operation. Both can be made good.
