Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a handrail attachment device. In particular, it relates to a handrail in which both ends of the handrail are attached to the vertical frame of a sash frame, the end plate of a door pocket, etc. via brackets, and the lower rail is attached to the lower frame of the sash frame via a support.

[Prior art and problems to be solved] In this type of conventional handrail mounting device, the support is screwed directly or indirectly to the lower frame of the sash frame, and it is difficult to attach the support to the sash frame on site. The installation was troublesome because it required positioning and drilling. Furthermore, once the holes are drilled and the supports are installed in advance, the holes must be re-drilled in order to adjust the position, and the previously drilled holes remain visible from the outside, degrading the appearance. As a result, it was virtually impossible to readjust the position.

[Means for solving the problem] The present invention was made in view of the above-mentioned conventional problems, and it is possible to attach both ends of the handrail cap to the vertical frame of the sash frame, the end plate of the door pocket, etc. via brackets, and to attach it by hand. The lower frame of the handrail is placed on the lower frame of the sash frame, the indoor side of the support part on which the lower frame of the handrail is placed has a mounting part for the lower frame of the sash frame, and the outdoor side has an upright piece for mounting a press screw. It should be installed via a support,
The support is fixed by slidingly fitting the mounting part to the mounting part of the lower frame, placing the lower crosspiece on the support part, and screwing the press screw through the upright piece. This is how it was done.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

Figures 1 to 3 are a longitudinal sectional view, a plan view, and an enlarged longitudinal sectional view of essential parts, showing an embodiment of the present invention, and as shown in each figure, the handrail 1 is connected to the sash frame 2. It is attached via a bracket 3 and a support 4.

The handrail 1 consists of a cap 5, a plurality of vertical bars 6..., and a lower bar 7, and the upper end of the approximately L-shaped vertical bar 6 is fixed to the cap 5 and the lower end to the lower bar 7 by screws. Become. 8 in the figure is a reinforcing crosspiece. The kasagi 5 and the sash frame 2 are connected by screwing the bracket 3 screwed to the right end of the kasagi 5 to the vertical frame 9, and the bracket 3 screwed to the left end of the kasagi 5 to the end plate 11 of the door pocket 10, respectively. It is fixed.

Further, the lower rail 7 of the handrail 1 has a mounting portion provided on the bottom side of the lower frame 12 of the sash frame 2, specifically, a pair of opposing groove portions 13a, 13 along the longitudinal direction of the lower frame 2.
A plurality of supports 4 are fitted and attached to b. This support 4 has the shape of a bent plate material as shown in FIG. It consists of an attachment part 15 to the support part 12 and an upright piece 16 folded up on the outdoor side of the support part 14.

The support part 14 has a flat plate shape and has a pair of small protrusions 17, 17 formed in the central longitudinal direction, and has a groove-like cross section formed by the outdoor side portion of the mounting part 15 and the upright piece 16. The mounting portion 15 is also substantially flat, and is formed to be offset upward from the support portion 14 in a stepwise manner. Both indoor and outdoor ends of this mounting portion 15 have dimensions that allow them to fit into the above-mentioned grooves 13a, 13b provided in the lower frame 12 of the sash frame 2, and the grooves 13a, 13
In order to make it easier to change the position by sliding it within b, the edges are rounded. Further, in the illustrated example, the indoor end of the mounting portion 15 has a stepped shape, but any shape that can be slidably fitted to the mounting portion of the lower frame 12 such as the grooves 13a, 13b may be used. It is not limited to. The upright piece 16 is provided with a screw hole 16a approximately in the center, through which a press screw 18 for fixing the lower frame 7 to the lower frame 12 of the sash frame 2 is screwed. Note that this support 4 may have a width that does not exceed the width between adjacent vertical bars 6, 6.

The sash frame 2 is made up of a pair of vertical frames 9, 9, an upper frame 19, and the above-mentioned lower frame 12, and includes a shoji 20,
20, shutters 21, 21, and screen door 22 are incorporated. The above-mentioned door pocket 10 is attached to the outdoor side of the vertical frame 9 on the left side. Further, on the bottom side of the lower frame 12, an opening 23 for inserting and attaching the support 4 is formed along the longitudinal direction on the outdoor side between the frame portion and the draining portion. Furthermore, the above-mentioned groove portion 13a provided in the lower frame 12,
13b, the indoor groove 13a is cut out to be wider than the width of the support 4 on both left and right sides, and after the sash frame 2 is assembled, the support 4 is inserted into the grooves 13a, 1.
3b. Of course, the notch may be provided only on one end of the left or right side of the lower frame 12, or may be provided in the groove 13b on the outdoor side instead of the groove 13a on the indoor side.

Next, how to attach the handrail 1 to the sash frame 2 in the device of this embodiment will be explained.

First, attach the assembled sash frame 2 to the window opening of the building. Next, the support 4 is inserted into the grooves 13a, 13 through the opening 23 at the end of the lower frame 12 where the notch is provided.
b, and the outdoor end of the attachment part 15 is fitted into the corresponding groove part 13b. With only one end side of the mounting part 15 fitted in this way, slide the support 4 so that the mounting part 15 does not come off the groove part 13b, and fit the indoor end into the corresponding groove part 13a. Slide it to near the position.

In this state, the lower crosspiece 7 of the handrail 1 is placed on the support part 14 of the support 4. Of course, the position of the support 4 is readjusted in advance so that the support 4 and the vertical beam 6 do not interfere with each other.

Furthermore, after screwing the cap 5 to the vertical frame 9 and the end plate 11 of the door pocket 10 via the flange 3, push the press screw 18 through the screw hole 16a provided in the upright piece 16 of the support 4.
, and press the lower frame 7 to the outdoor side of the lower frame 12 to complete the installation. In addition, in this state, the lower crosspiece 7 is attached to the small protrusion 17 provided on the support part 14 of the support 4.
17, the frictional resistance during sliding is small, and the position of the support 4 can be easily readjusted by slightly loosening the press screw 18.

[Effects of the invention] As explained above, the handrail mounting device according to the present invention has a structure in which the mounting part of the lower frame of the sash frame is attached to the indoor side of the support part on which the lower rail of the handrail is placed. Attach the lower rail of the handrail to the lower frame of the sash frame via a support having an upright piece on the outdoor side into which a pressure screw for positioning and fixing is screwed. Because the support is fitted to the lower frame of the sash frame in advance, it is possible to fit the support to the lower frame of the sash frame and install it, allowing it to be freely adjusted according to the position of the lower frame, etc. before fixing the position with the press screw. Since there is no processing involved, it has the advantage of being easy to implement on-site.
