Description

[Detailed description of the invention] The present invention has a rotating roller or sliding body that is fixed to the upper end of a folding sliding door with a door roller at the lower end corresponding to the door roller, and rotates within the guide groove of the upper frame. Or it relates to a guide member that guides a sliding door by sliding in cooperation with a door roller.

Conventionally, to attach a folding sliding door to a building's mounting frame, from the side edge of the mounting frame, insert the door roller into the guide groove of the lower frame and the guide roller into the guide groove of the upper frame, one slat at a time. method is being adopted.

However, this method requires time and requires that the entire sliding door be held at a constant height until the last slat is inserted.

Another disadvantage is that the installation work is troublesome and requires manpower.

Therefore, the present invention was made with the aim of eliminating such drawbacks, and relates to a guide member for a folding sliding door that allows the installation of the sliding door from the front of the mounting frame and facilitates the installation work. The main body is fixed to the upper end of the sliding door, the shaft is attached to the main body so as to be slidable up and down, and the upper guide provided on the upper end of the shaft is attached to the building side when the shaft is in the raised position. It consists of a rotating roller or sliding body that engages with the groove and a means for holding the shaft in the raised position, and when the folding sliding door is attached to the sliding door mounting frame, the shaft is lowered to the lowered position. The present invention relates to a guide member characterized in that the shaft rod is configured to be able to be held in a raised position.

The present invention will be explained below with reference to embodiments shown in the drawings.

In Fig. 1, reference numeral 1 denotes a main body formed by bending a metal plate into a U-shaped cross section, and the opposing upper plate 1a and lower plate 1b have through holes 3at3b through which the shaft rod 2 is slidably inserted. Each is drilled.

A saw blade-like notch 4 whose inclined surface faces upward is provided on the side surface of the shaft rod 2.

Since this allows for rising but prevents falling in relation to the tip of the leaf spring, which will be described later, other shapes may be used as long as this purpose can be achieved.

Reference numeral 5 denotes a rotating roller made of soft rubber that is pivotally attached to the upper end of the shaft rod 2, which is fitted into the upper guide iD of the mounting frame and rotates within the premises as the sliding door moves, as will be described later. However, it may be one that simply slides within the premises without rotating.

Reference numeral 6 denotes a leaf spring that acts between the side plate IC of the main body 1 and the shaft rod 2, and is formed by bending a single piece of material.
is engaged with the notch 4 provided on the side surface of the shaft rod 2, and the other end is a mounting section, and both sides are S. The lower plate 1b is attached with some space left between the vicinity of the lower bent portion 6c of the portion and the lower plate 1b.

Therefore, the mounting portion of the leaf spring 6 and the side plate 1c are in close contact with each other, but they are slidable by the gap between the lower bent portion 6c and the lower plate 1b.

7 is an operating piece fixed to the lower end of the shaft 2, and 8 is a cover of the main body 1.

In FIG. 2, A is the guide member according to the present invention, B is the folding sliding door, C is the door roller, D is the upper guide groove of the sliding door mounting frame, and E is the lower rail.

The guide member A according to the present invention is fixed to the upper end of the sliding door B with screws or the like in correspondence with the door roller C.

When installing this folding sliding door B, first, all the shaft rods 2 of the guide members A are in a lowered state.

This is done by twisting the operating piece 7 approximately 90 degrees to
This can be done by placing a at a position that does not correspond to the notch 4 and pulling it down, and after pulling it down, move the operating piece 7 again to about 90
Twist it enough so that the notch 4s at the top engages with the tip 6a of the leaf spring 6.

Next, when all the door rollers C of the folded sliding door B are placed on the lower rail E from the front of the mounting frame, the weight of the sliding door B will be supported by the rail E.

Next, the sliding door B is made to stand upright so that its upper end is directly below the upper guide groove, and the shaft rod 2, which is the lower part, is raised.

That is, when the operating piece 7 of the shaft rod 2 is pinched and pushed up, since the inclined surface of each notch 4 provided on the side surface of the shaft rod 2 faces upward, the tip 6a of the leaf spring 6 moves into each notch 4 due to its elasticity.
The shaft rod 2 is allowed to rise while repeating engagement with and withdrawal from the roller, and stops when the upper end of the rotating roller 5 reaches the upper bottom of the upper guide groove.

At this rising stop position, the tip 6a of the leaf spring 6 engaged with one of the notches 4 is restricted by the horizontal portion of the notch 4, preventing the shaft 2 from descending and maintaining this position.

However, since there is some gap between the vicinity of the bent portion 6c of the leaf spring 6 and the lower plate 1b, when a downward force is applied to the rotating roller 5, the tip is inserted into the notch 4 of the shaft rod 2. The locked leaf spring 6 has room to relatively slide downward while remaining in contact with the side plate 1c at the attachment portion.

Note that what is illustrated is one embodiment of the present invention, and the present invention is not limited to this.

Since the present invention is constructed as described above, the sliding door can be easily installed from the front, and has excellent effects in that it is easy to operate and does not require manpower.

Furthermore, when using soft rubber for the rotating roller,
It is also possible to prevent noise from being caused by wind or the like.
