Description

[Detailed Description of the Invention] This invention relates to a connecting device between a lower frame formed in the shape of a descending staircase and a mullion vertically connected to the lower frame.

Even in a descending staircase-shaped bottom frame, the shape (height) of the rising part is different between the standard type bottom frame and the highly watertight type bottom frame, and in such cases, conventionally, the bottom edge of the mullion was The work efficiency was very poor because each part was milled to match the shape of the lower frame.

Conventionally, in order to eliminate the above-mentioned problems, a connecting device was generally used in which the lower end of the mullion was cut flat regardless of the shape of the lower frame, and the space between the mullion and the lower frame was closed with a block. It was known (Jikko 53)
-Refer to Publication No. 26029).

However, in the case of such a connecting device, there is a big difference between the product precision of the bottom frame and the precision of the parts of the block, and it is extremely difficult to ensure watertightness and airtightness between the mullion and the bottom frame. It was hot.

This invention was devised in view of the above points, and the purpose is to provide a connection device between the mullion and the bottom frame that is excellent in watertightness and airtightness and has good workability. be.

This invention will be explained below based on embodiments shown in the drawings.

The lower frame 1 is formed in the shape of a staircase descending from the indoor side to the outdoor side. The upper part of the lower frame 1 is configured as a fitting groove 2 having a concave cross section.

A vertical wall 3 is formed integrally with the fitting groove 2 from the back surface near the indoor end of the fitting groove 2,
A projecting wall 4 projects from the lower end of the vertical wall 3 toward the outdoor side, and a rail 5 projects from the outdoor side of the projecting wall 4, constituting the lower part of the lower frame 1.

A notch 7 into which the lower end of the mullion 6 fits is formed in the upper part of the lower frame 1. This notch 7 is formed by cutting out both groove walls 8, 8 of the fitting groove 2, which is formed to have a concave cross section.

When connecting the mullion 6 and the lower frame 1, a substantially L-shaped connecting member 9 is used. This connecting member 9 is connected to the groove bottom wall 10 of the fitting groove 2 in the lower frame 1 and the side surface 11 of the mullion 6 with screws 12 .

At this time, the mounting hole 23 formed in the groove bottom wall 10 of the lower frame 1 is formed on the outside of the room from the position where the vertical wall 3 hangs down. By drilling the mounting hole 23 in such a position, even if rainwater enters from this location, the rainwater will flow through the mounting hole 23...
The water will flow out of the room through the pipe, so there is no risk of corroding the foundation (not shown) or the like.

By the way, a gap is formed in front of the lower end of the mullion 6. This gap is the groove bottom wall 1 of the fitting groove 2.
0, vertical wall 3, overhanging wall 4, vertical wall 3 and overhanging wall 4
and an intermediate step section 13 between.
In order to close this gap, first, a lower windshield plate 14 is attached to the overhanging wall 4. The lower wind stop plate 14 is fixed by fitting the end of the lower wind stop plate 14 into the groove 15 formed at the lower end of the intermediate step portion 13 and attaching the rising piece of the lower wind stop plate 14 to the side surface of the rail 5. This is done by bringing 16 into contact with each other.

Next, the lower wind stop plate block 17 is inserted into the gap from above the lower wind stop plate 14.

By the way, as shown in FIG. 3, the lower wind stop block 17 includes a block main body 18 molded from synthetic resin or the like, and a vinyl chloride block body 18 that is attached to both sides of the block main body 18 and has portions protruding from the outer periphery of the both sides. Soft fin members 19, 19 made of etc.
and clamping members 20, 20 for clamping the fin members 19, 19.

This lower wind stop block 17 is assembled by drilling fitting holes 21 on both sides of the block body 18, and fitting protrusions 22, 22 into the clamping members 20, 20.
This is done by forming the fitting protrusion 22 into the fitting hole 21.

This lower wind stop block 17 has a shape that is almost the same as the shape of the lower part of the lower frame 1 that forms the gap in front of the lower end of the mullion 6, and is connected to the groove bottom wall 10 of the fitting groove 2, the vertical wall 3, and the intermediate stage. It is fitted into the gap formed between the portion 13 and the overhanging wall 4 and is attached.

Incidentally, when forming the lower frame 1, a certain amount of error occurs, but this error can be absorbed by the fin member 19 of the lower windstop block 17.
It can be completely watertight and airtight.

Further, although the height of the vertical wall 3 is different between the standard type lower frame 1 and the highly watertight type lower frame 1, it is sufficient to prepare the lower windstop block 17 for each type of lower frame 1.

Note that the lower wind stop block 17 is fixed by a screw 12 screwed into the groove bottom wall 10 of the fitting groove 2; Even if rainwater or the like enters the mounting hole 23 drilled in the mounting hole 23, the rainwater will flow out to the surface side of the overhanging wall 4, and there is no risk of corroding the foundation or the like.

Thus, this idea consists of the above structure. In the connection device between the lower frame and the mullion according to this invention, the lower wind stop plate and the lower wind stop block having the fins are inserted in a double manner into the gap in front of the lower end of the mullion. Even if there is a difference in the product accuracy of the lower frame and the component accuracy of the block, it can be absorbed and watertightness and airtightness between the mullion and the lower frame can be ensured.
