Description

[Detailed description of the invention] This invention is designed to install a handrail on the exterior frame for renovation, which is installed on the outside of the room by spanning the old and new vertical frame parts when a new metal window frame is installed on top of the existing window frame. The present invention relates to a mounting structure that allows for the attachment of a.

In order to save the great effort and expense of removing the old window frame and then installing a new window frame, it is possible to fix the new window frame on top of the window frame without removing it. It is being done.

In this case, it is difficult to prepare new window frames with a wide variety of shapes corresponding to the various shapes of the old window frames, so we prepare new window frames that are the greatest common divisor. Attach this to the enclosure frame using spacer hardware, anchor hardware, or other adjustment pieces, and attach the external frame to the outdoor side, spanning both the old and new frames.
I added a frame to the inside of the room to improve my appearance.

However, it would be a waste of money if the frame simply served the role of hiding the joint between the old and new frames.

The present invention was made from this perspective,
The external frame of the vertical frame serves to attach a handrail.

This will now be explained with reference to FIG. 1, which is an example of a partial cross-section of a state in which the external frame for renovation according to the present invention is attached to the vertical frame portion including the old and new vertical frames, and a handrail is attached.

In the figure, 1 is the old vertical frame part including the column-like window frame frame and the old vertical frame attached to it, and the new vertical frame 2 is fixed to the old vertical frame 1 via the anchor hardware 3. There is.

The fixation is achieved by welding or bolting the metal substrate 3a to the old frame 1, and the distance between the new vertical frame 2 and the old vertical frame 1 is such that the locking plate 3C that locks the new vertical frame 2 and the substrate 3a are fixed. This is done by adjusting the length of the tied legs 3b.

The spacer hardware 4 is an angle-shaped member, and its outer plate 4a is fixed to the old vertical frame part 1 with bolts 9, and the four-dimensional plate 4b
is fixed to the new vertical outermost wall 2a by bolts 10.

The external attachment frame 5 for renovation has an outer wall 5a having a width that substantially hides the spacer metal fittings 4 described above, and an inner wall 5b having a longitudinal handrail fitting groove 5c in the center, which are bent to have an L-shaped cross section. As shown in the figure, the outer end of the outer wall 5a is a metal section having a shape, and the bolt 11 is attached to the mounting portion 4c formed by bending the outer plate 4a.
The end of the inner wall 5b is fixed with a bolt 12 to a mounting portion 4d formed by bending the inner plate 4b of the spacer hardware, thereby fixing both the old and new vertical frames together.

In the figure, when fastening the bolt 11 between the outer end of the outer wall and the mounting portion 4c of the spacer metal fitting, the back-up material 14 is traditionally made into one piece.
The state in which the aluminum angle adjustment hardware 13 fixedly attached is also bolted together is shown.

This is an example of covering the old and new vertical frames in a way that adapts them to their dimensions.

Note 15 indicates caulking material.

A handrail fixture 6 shown in FIG. 2 is fitted into a handrail fixture groove 5c provided longitudinally in the center of the inner wall 5b.

The fixture consists of a bottom part 6a that can slide in the groove 5c, and a protrusion 6b rising perpendicularly from the bottom part 6a.
is fitted into the mounting groove 5c, which has a narrowed shape at the entrance, and is moved to the desired handrail height position, where the third
As shown in the figure, it is fixed in the groove 5c with a screw 16.

In this way, the protruding portion 6b protrudes from the entrance of the narrowed groove, but the bottom portion 6a does not come out of the groove.

The handrail material γ is a long material that has an inner shape that can be fitted onto the protrusion 6b of the fixture, and has a rectangular cross-sectional shape that fits the rectangular protrusion 6a in Figure 11. A hollow RA member is shown.

If you wish, the outer shape can be circular, polygonal, oval, etc.

Preferably, it is made of a synthetic resin such as polyvinyl chloride as a mold material.

Although only the left formwork part is shown in FIG. 3, the right formwork part appears symmetrically thereto.

Instead of 54, the handrail is inserted between the external frames of both the left and right vertical frames by inserting the hollow part of the handrail material 7 between the protrusions 6b and 6b of the fixture that is fitted and fixed to the external frames of both the left and right vertical frames. It will be done.

Of course, it is also possible to provide handrails in two or three stages as desired, which is a repetition of the above process and is self-evident.

Among them, the reference numeral 8 in the figure is attached so as to cover the old and new vertical frame parts on the indoor side in correspondence with the external frame, but this has no relation to the structure of the present invention.

[Brief explanation of drawings]

Attached Fig. 1 is a cross-sectional view of the left window form with an external frame attached to it, which is an embodiment of the present invention, Fig. 2 is a perspective view of the handrail fixture, and Fig. 3 shows the state in which the handrail is attached. It is a perspective view of the left formwork part shown. 1 is the old vertical frame, 2 is the new vertical frame, 3 is the anchor hardware, 4 is the spacer hardware, 5 is the external frame, 6 is the handrail fixture, 7 is the handrail material, 8 is the internal frame, 9, 10. IT, 12 is a bolt, 13 is an adjustment hardware, 14 is a buffer rough material, 15 is a caulking material, and 16 is a screw.
