Description

[Detailed description of the invention] The present invention has a mounting hardware 3 having supporting pieces 2 on both sides attached to the lower surface of the sliding door frame 1, and a fitting piece 5 protruding outward from the lower part of one side of the rail group fitting part 4. Fitting block 12
The fitting piece 5 of the fitting block 12 is inserted into the mounting hardware 3 and supported by both support pieces 2, and the end of the rail 6 having an inverted cross section is fitted into the rail group fitting 4. This relates to a structure for attaching a rail to a sliding door frame, which is secured with screws 7.

The conventional structure for attaching a rail to a sliding door frame is such that the rail is directly fixed to the sliding door frame.

For this reason, during construction, the rail was directly assembled into the sliding door frame and installed at the entrance of the house, and then concrete was poured. The rail was positioned above the rail and suspended in the air, and if a load was applied to the rail during this time, it would deflect downward, causing the rail to lose its accuracy.

The present invention was devised in view of the above points, and its purpose is to attach a mounting hardware to the lower end surface of the sliding door frame, attach the fitting piece of the fitting block to the fitting, and attach the fitting piece of the fitting block to the fitting part of the fitting block. By fitting the ends of the rails and securing them with screws, the rails can be attached to and removed from the sliding door frame, creating a sliding door frame that allows the rails to be attached even after the sliding door frame is attached to the entrance and concrete is poured. Provides rail mounting structure.

The present invention will be explained in detail below using examples.

In the figure, reference numeral 1 denotes a sliding door frame, which is provided with a recessed groove 8 on its lower surface.A mounting hardware 3 is fitted into this recessed groove 8, and a top piece 9 of the mounting hardware 3 is attached to the upper bottom surface of the recessed groove 8 with a screw 10. It's stuck.

The mounting hardware 3 has L-shaped support pieces 2 on both sides of the top piece 9, and a substantially triangular locking protrusion 11 projects from the inside of the L-shaped support piece 2.

In the figure, reference numeral 12 denotes a fitting block, in which a fitting piece 5 extends from the bottom of one side of the rail group fitting part 4 having an inverted cross section, and a locking recess notch 13 is provided on both sides of the fitting piece 5. be.

The fitting piece 5 is divided into two parts by a cut 14 parallel to the extending direction from the rail group fitting part 4.

Screw holes 15 are bored on the upper surface and both sides of the rail group inset portion 4.

6 in the figure is a rail with an inverted cross section, and a door 16 on the top surface.
A protruding strip 17 is provided for the vehicle to run on, and holes 18 are perforated on the top surface and both sides.

Then, the fitting piece 5 of the fitting block 12 is fitted into the mounting hardware 3 attached to the lower end surface of the sliding door frame 1, and the end of the rail 6 is fitted into the rail group fitting part 4 of the fitting block 12. Then, the screw 7 is inserted through the hole 18 and screwed into the screw hole 15 to secure it.

Here, the fitting piece 5 is supported by the support piece 2, but in this case, the locking protrusion 11 is fitted into the locking recessed notch 13, and when fitting, it is divided into two by the presence of the notch 14. The fitting piece 5 is elastically deformed and fitted.

By the way, in the present invention, unlike directly fixing the rail 6 to the sliding door frame 1, the mounting hardware 3 and the fitting block 1 are
Since the rail 6 is attached with screws 7 through 2, the rail 6
In this work, the sliding door frame 1 with the mounting hardware 3 attached is attached to the entrance of the house, and then it is fitted when pouring concrete on the floor. When this is completed, the end of the rail 6 can be fitted into the rail group fitting portion 4 of the fitting block 12 and fixed with screws 7, thereby making it possible to install the rail 6.

Therefore, in the present invention, instead of directly fixing the rail 6 to the sliding door frame 1 as described above, a mounting hardware having a fitting block 12 consisting of a rail group fitting part 4 and a fitting piece 5 and a support piece 2 is used. 3, the rail 6 can be installed even after the sliding door frame 1 has been installed at the entrance of the house and the floor has been poured with concrete. It is not necessary to install the rail directly at the entrance of the house and then pour concrete, and there is no need for the rail to be in a floating state until the concrete is poured. This has the advantage that the load from the rail 6 does not bend too much and the accuracy of the rail 6 does not deteriorate.Furthermore, the fitting piece 5 extending from the lower part of one side of the rail group fitting part 4 can be inserted into the mounting hardware 3. Since it is supported by both supporting pieces 2, the fitting block 1
When attaching to the mounting hardware 3 of No. 2, it can be accurately attached by a simple means of fitting.

Moreover, since the rail 6 can be attached by being fitted into the rail group fitting portion 4 from above, the attachment of the rail 6 is simplified.
