Description

[Detailed description of the invention] The present invention relates to the improvement of the connection device between the vertical stile and the horizontal stile of a door panel.
A fixing block 2 is inserted into the inner end of the vertical stile 1 so that the end surface is located slightly inward from the end surface of the vertical stile 1, and a screw hole 3 is bored from the end surface of the fixing block 2. A vertical stile 1 is provided at the end of a horizontal stile 4 made of synthetic resin, the longitudinal direction of which is perpendicular to the longitudinal direction of the vertical stile 1, with an inclined surface 6 provided inside the end so as to cut out a corner. A notch 5 is provided in which the end of the vertical stile 4 can be fitted, and an inclined surface 7 having the same slope as the above-mentioned inclined surface 6 is provided at the inner end of the notch 5, and the notch 5 of the horizontal stile 4 is fitted into the end of the vertical stile 1. , insert the mounting screw 11 into the screw hole 3 of the fixing block 2 from the horizontal stile 4 from the inside of the extension line a of the screw hole 3, and insert the upper end of the vertical stile 1 into the notch 5. The inclined surface 6 of the vertical stile 1 is
This relates to a connecting device between a vertical stile and a horizontal stile of a door panel, in which the slanted surface 7 of the notch 5 and the slanted surface 7 of the notch 5 are brought into close contact with each other.

Conventionally, as shown in FIG. 4, the lower end of a horizontal stile 4 made of synthetic resin is placed on the upper end surface of a vertical stile 1 made of synthetic resin, and the mounting screws are inserted from the horizontal stile 4. 11 is screwed in and the vertical stile 1 and the horizontal stile 4 are elastically deformed to connect them in close contact.
Vertical stile 1 and horizontal stile 4 are certainly connected around the mounting screw 11.
Although the stile 4 was closely connected to the stile, the other parts of the stile 4 were bent and floated, forming a gap 23 at the inner corner, making it impossible to connect airtightly and watertightly.

The object of this invention is to provide a connecting device for the vertical and horizontal frames of a door panel, in which the inclined surface of the notch and the inclined surface of the vertical frame are brought into close contact with each other by the inclined surfaces biting into each other, and the notch and the end face of the vertical frame are brought into close contact by elastic deformation of the end of the vertical frame, thereby enabling the vertical and horizontal frames to be connected watertightly and airtightly.

The present invention will be explained in detail below with reference to Examples. Reference numeral 1 is a vertical frame with a hollow interior made of synthetic resin, and a face plate fitting groove 8 is provided in the vertical direction on one inner side.
is recessed, and a notched inclined surface 6 is provided on the face plate fitting groove 8 side of the upper end. A fixing block 2 made of synthetic resin has a screw insertion hole 3 drilled in its end surface, and a fixing hole 3 in its side surface. The fixing blocks 2 are inserted into the upper and lower ends of the vertical stile 1, respectively, so that the end surfaces of the fixing blocks 2 are located slightly inward from the end surfaces of the vertical stile 1. The fixing screw 10 is screwed into the fixing hole of the fixing block 2 from the side of the fixing block 2 to fix the fixing block 2. 4 is a horizontal stile made of synthetic resin, and a face plate fitting groove 12 is provided on one side of the horizontal stile 4. A notch 5 into which the end of the vertical stile 1 can fit is provided at both ends of the horizontal stile 4, and an inclined surface 7 having the same slope as the above-mentioned inclined surface 6 is provided on the side of the face plate fitting groove 12 of the notch 5. , and further notch 5
And on the front and back of the slope 7, there are fins 1 that go inside the vertical stile 1.
3 is provided. When assembling the door panel A, a pair of vertical frames 1 are placed opposite each other so that the face plate fitting grooves 8 are opposite each other, and a face plate 14 such as a glass plate or a synthetic resin plate is inserted between the face plate fitting grooves 8. Then, span the horizontal stile 4 between the upper and lower ends of the vertical stile 1, fit the face plate fitting groove 12 of the horizontal stile 4 into the face plate 14, and fit the end of the vertical stile 1 into the notch 5 of the horizontal stile 4. Fit and attach fin 13 to vertical stile 1
Put it inside. Next, as shown in FIG.
is screwed into the screw hole 3 through the horizontal stile 4 to connect the vertical stile 1 and the horizontal stile 4. At this time, the inclined surfaces 6 and 7 bite into each other and come into close contact, and the end of the vertical stile 1 is slightly elastically deformed, so that the end face of the vertical stile 1 comes into close contact with the notch 5 of the horizontal stile 4, providing airtightness and watertightness. . Note that notch 5
In addition, when the fins 13 are provided on the inclined surface 7, airtightness and watertightness are further improved.

The door panel A configured as described above is attached to the hinge 15.
are rotatably connected to form a bifold door. In the figure, 16 is a pivot, 17 is a runner, and 18 is a handle. Bifold door A has upper frame 1
0, it is attached to an opening frame B formed by a lower frame 20 and left and right frames 21 and 22 so as to be openable and closable, and can be opened and closed using a handle 18.

As described above, the present invention is a fixing block that is inserted into the inner end of a hollow vertical stile made of synthetic resin so that the end surface is located slightly inward from the end surface of the vertical stile. At the same time, a notch is provided at the end of the horizontal stile made of synthetic resin into which the end of the vertical stile can fit, so the notch of the horizontal stile fits into the end of the vertical stile, By screwing the mounting screw into the screw hole of the fixing block, the part of the vertical stile that protrudes from the fixing block is elastically deformed and tightly fits into the notch of the horizontal stile, and in this case, the vertical stile and Since the horizontal stile is made of synthetic resin, the parts that protrude from the fixing blocks of the vertical stile and the notches of the horizontal stile will float apart except around the area where the mounting screws are screwed in, and there will be a gap at the inner corner. However, by notching the corner on the inside of the vertical stile end and providing a sloped surface, and by providing a sloped surface with the same slope as the vertical stile slope on the inside edge of the cutout of the horizontal stile, The notch of the horizontal stile is fitted to the end, and the mounting screw is inserted from the inside of the extension line of the screw hole into the screw hole of the fixing block from the horizontal stile, making installation easy. When the screws are inserted, the end of the vertical stile and the notch of the horizontal stile slide in opposite directions along the longitudinal direction of the horizontal stile, causing the sloped surface of the vertical stile and the sloped surface of the notch to press against each other. This prevents the formation of the above-mentioned gap due to the biting of the slope.In this way, the elastic deformation of the end of the vertical stile and the slope of the vertical stile and the slope of the notch of the horizontal stile are Due to the biting, the vertical stile and the horizontal stile can be firmly attached and connected airtightly and watertightly without forming any gaps.
