Description

[Detailed Description of the Invention] The present invention relates to an installation device for fittings (sliding doors) for railless window frames.

The lower frame of a metal window frame, typified by an aluminum sash, has a rail provided in its upper surface in the longitudinal direction to guide the sliding door.

However, rainwater and dust tend to accumulate between these rails, and it is difficult to remove them.

Therefore, recently, what is called a railless window frame, the lower frame has several levels of flat parts and standing walls, and each level has a front hanging wall to form the door guide part. In addition to providing an angle, fix an L-shaped lower stile cap made of resin to this and fit it into the sliding door guide part to hold the fittings, or
2) In the example of 1) above, the L-shaped angle is eliminated and an L-shaped synthetic resin lower stile cap is fitted into the chisel and door guide part to hold the fittings.

Furthermore, 3) As the simplest known example, an L-shaped locking piece is screwed to the lower stile and this L-shaped locking piece is hooked on the sliding door guide part to hold the fittings. In the case of using a stop piece, the rails are moved by a sliding door installation device, as shown in Utility Model Publication No. 56-2787, in which an L-shaped steady stop is moved up and down by an adjustment piece with a slope and an adjustment bolt. This allows the fittings to be opened and closed even when not in use.

However, in the example shown in 1), a large amount of material is required to form the L-shaped angle, and there is a disadvantage that dust accumulates in the L-shaped part, and in the example shown in 2), the lower stile is Since the sliding door is held only by the L-shaped portion of the cap, this lower stile cap has the disadvantage of being easily damaged.

Furthermore, in the example shown in 3), the L-shaped locking piece is only secured with screws, so it is necessary to tighten the screws, and the screws may loosen and fall off if used for a long time.

In addition to the above-mentioned drawbacks, the conventional ones described in 1) to 4) above do not have a kendon type, so slide the fittings from one end of the lower frame and attach the L-shaped locking piece to the sliding door. It has the inconvenience of having to fit it into the guide.

The example shown in 3) can be made into a simple type by loosening the screws, but this requires laborious work such as loosening and tightening the screws.

Furthermore, although the example shown in 4) has the function of adjusting the steadying device (locking piece) up and down, it cannot be easily built in the erecting type.

Therefore, we have developed a sliding door installation device with a structure that completely eliminates the above-mentioned drawbacks.

The feature is that the sliding door guide piece that engages and disengages from the conventionally known sliding door guide part is formed into a groove shape consisting of a long piece and a short piece, and the sliding door guide piece is attached to the lower side of the mounting base to the lower stile. A notch is formed to restrict the rise of the long piece, and a through hole is formed for each of the long pieces at the upper corner of the side surface, and a push-up spring is installed between the base and the long piece for attachment to the lower stile. be.

With this structure, after fitting the upper edge of the sliding door upper stile to the upper frame of the window frame, you can push down the long piece of the sliding door installation device with your hand or foot, without loosening screws, etc. as with conventional products. It can be built using the so-called kendon style, in which the lower stile is fitted into the lower frame with the lower stile held in place, and when a hand or foot is removed from the long piece, the short piece engages with the sliding door guide.

The apparatus according to the present invention will be explained in detail below with reference to the drawings.

The drawings show one embodiment of the present invention; Fig. 1 is a partially cutaway perspective view of the sliding door installation device, Fig. 2 is a vertical cross-sectional view of section A-A in Fig. It is a longitudinal cross-sectional view showing a state.

As shown in FIG. 3, the sliding door installation device 1 of the present invention has the following features:
In contrast to the lower frame construction of a railless window frame which is shaped like several steps with a plane part 2 and a standing wall 3 and has a sliding door guide part 4 formed on the front side of the standing wall 3, it is possible to install a sliding door 7 such as a rain door or a sliding door. Lower stile 8
The sliding door guide piece i, which is movable up and down, engages with the sliding door guide part 4 of the lower frame and is attached so as to be slidable back and forth.

To explain in more detail with reference to FIGS. 1 and 2, the sliding door guide piece 6 is made of a groove-shaped metal piece consisting of a short piece 18, a groove part 16, and a long piece 15, or a synthetic resin having the same strength. In this example, the common installation with door roller 9 is base 12.
It is set in.

The mounting structure of the sliding door guide piece 6 to the base 12 includes a notch 13 that allows the sliding door guide piece to move up and down below the side surface of the mounting base 12 and restricts it from rising above a certain level.
Furthermore, through holes 14 are formed in the upper corners of the side surfaces of the mounting base 12, and long pieces 15 are formed in the through holes 14, and long pieces 15 are formed in the notches 13.
are normally held resiliently against the upper part of the notch 13 by springs 17 through the grooves 16, respectively.

Therefore, when the sliding door guide piece 6 is pushed down with hands and feet, it easily descends, and when released, it immediately returns to its original position.

The door wheel 9 is provided so that its height can be adjusted around a rotation shaft 11 by adjusting a screw 10.

When in use, the short piece 18 is attached to and detached from the sliding door guide part 4 of the bottom frame as shown in Fig. 3, but it is made of synthetic resin, rubber, etc. to prevent noise when opening and closing the sliding door or when there is strong wind. It is preferable to cover the short piece 18 with a cap 19 consisting of.

By simply screwing the structure described above to both ends of a lower stile mounting base such as a sliding door, it can be used in conjunction with a railless window frame.

Moreover, it can be installed at low cost without sacrificing the 19 strength of the rail-less window frame from which dirt, sand, etc. can be easily removed.In addition, the sliding door equipped with this sliding door installation device requires no tools. It is possible to easily erect it in the Kendon style by simply pushing down the long piece with your hands or feet, without having to do any work such as loosening screws.

Moreover, the structure is simplified and can be provided at low cost, such as by providing a sliding door guide piece on the common base with the door roller.
