Description

The present invention relates to a mounting structure for a sliding panel, a cover member, and a method for installing a sliding panel.

2. Description of the Related Art Conventionally, slide panels have been known in which a panel such as a sliding door is suspended from a rail fixed to a top frame or a side frame so as to be able to be opened and closed.
Conventional sliding panels enable movement by inserting hanger rollers into upper rails that fit into grooves in horizontal frames.
The height of the hanging type sliding panel is made small to prevent interference with the horizontal frame when fitting it into the upper rail, so the shaft connecting the hanger roller and the sliding panel inevitably protrudes from the bottom end of the horizontal frame. In other words, a gap is created between the horizontal frame and the sliding panel. Similarly, when the upper rail is attached to the flat bottom surface of the horizontal frame that does not have a groove for fitting the rail, a gap is created between the steel plate attached from the horizontal frame to the upper rail and the top end surface of the sliding panel.
Such gaps would allow light from inside the room to leak outside (or allow light from outside to enter the room) and allow wind to pass through, so the invention in Patent Document 1 uses a rubber member that rises vertically and extends across the width of the panel on the upper end surface of the sliding panel to suppress light leakage, etc.

However, in the conventional slide mounting structure such as that in Patent Document 1, the rubber member appears between the slide panel and the horizontal frame or its decorative plate, which mars the appearance. In addition, depending on the design between the horizontal frame and the upper end surface of the slide panel, the dimensions of the rising wall of the rubber member to be used must be carefully set in consideration of interference with the horizontal frame and light blocking, and many different types of rubber members must be used depending on the design, which is cumbersome.
Therefore, the present invention provides a mounting structure for a sliding panel that can be easily attached to a horizontal frame to close the gap formed above the upper end surface of the sliding panel, a cover member used therewith, and a method for installing a sliding panel.

The mounting structure for a sliding panel of the present invention comprises a hanger rail fixed to a horizontal frame, a hanger roller attached to the hanger rail, and a sliding panel fixed to the hanger roller and suspended movably from the hanger rail, and has a cover member on either or both of the front and rear sides of the sliding panel that covers from the horizontal frame to at least the upper end of the sliding panel.
According to this configuration, the cover members can be attached separately to the front side and the rear side of the slide panel, which makes it easy to attach the cover members.

The cover member of the mounting structure for a slide panel of the present invention may have a top wall portion and a side wall portion bending and extending vertically from an edge of the top wall portion, and the top wall portion may be capable of being fixed to an upper end surface of the horizontal frame.
According to this configuration, the cover member can be fixed to the upper surface of the horizontal frame, thereby enabling the cover member to be fixed with good design.

The cover member of the mounting structure for a slide panel of the present invention is provided with an engaging portion used when fixing it to the horizontal frame, and the horizontal frame is provided with an engaged portion for engaging the engaging portion of the cover member, and the engaging portion and the engaged portion may be engaged with each other in an irremovable manner once they are engaged with each other.
According to this configuration, the cover member can be attached even more easily.

The cover member of the present invention is used in the mounting structure for the slide panel of any one of the above-mentioned inventions.
With this configuration, the cover member can be easily attached from the horizontal frame to the upper end of the slide panel.

The method for installing a sliding panel of the present invention includes a panel mounting step of mounting a sliding panel via a hanger roller to a hanger rail fixed to a horizontal frame, and a cover mounting step of mounting a cover member covering either the front side or the back side of the horizontal frame and the sliding panel to either or both of the front side and the back side after the panel mounting step.
With this configuration, the cover member can be easily attached from the horizontal frame to the upper end of the slide panel.

The mounting structure for the sliding panel, the cover member used therein, and the method for installing the sliding panel of the present invention have the effect of being easily attached to the horizontal frame and sealing the gap formed above the upper end surface of the sliding panel.

Below, we will explain one embodiment of the mounting structure for a sliding panel of the present invention, the cover member used therein, and the method for installing the sliding panel, with reference to the drawings.

As shown in FIG. 1, the mounting structure 1 for a sliding panel of the present invention is applied to, for example, a middle horizontal frame (horizontal frame) 4 between a shoji window 2 and a hanging-type sliding door (sliding panel) 3, which are provided in an opening W1 formed in a side wall W of a building.

Specifically, a pair of vertical frames 5 on the left and right, an upper horizontal frame 6, and a middle horizontal frame 4 are provided in an opening W1 in a side wall W of a building, and a shoji window 2, 2 is installed between the upper horizontal frame 6 and the middle horizontal frame 4. Sliding doors 3, 3 are installed between the vertical frames 5, the middle horizontal frame 4, and the floor surface F (or a lower horizontal frame without a doormat in some cases), and a sliding panel mounting structure 1 is used for the middle horizontal frame 4. More specific applications include school classrooms and entrances to each room in a building.

The structure of each component will be described in detail below.
The vertical frame 5 is fixed with screws or the like to the left and right inner end faces of an opening W1 formed in a side wall W of the building.
The upper horizontal frame 6 is attached so as to face the upper inner end surface of the opening W1, for example by fixing both ends to the upper ends of the vertical frame 5.
The middle horizontal frame 4 is a batten member with an approximately rectangular outline when viewed from the side, fixed to the left and right vertical frames 5 with a gap between it and the upper horizontal frame 6 that allows the shoji window 2 to be installed.

As shown in FIG. 2, upper and lower metallic shoji rails 7a, 7b are fixed to the lower surface 6b of the upper horizontal frame 6 and the upper surface 4a of the middle horizontal frame 4, respectively.
The upper shoji rail 7a has two parallel convex bars 7y extending in its longitudinal direction (depth direction on the paper) and spaced apart in the width direction of the rail, and the convex bars 7y are fixed to the upper horizontal frame 6 with they protrude downward.

The lower shoji rail 7b has two parallel convex strips 7y extending in its longitudinal direction (depth direction on the paper) and spaced apart in the width direction of the rail, and the convex strips 7y are fixed to the middle horizontal frame 4 with their protruding upward.
The two protruding strips 7y, 7y of the upper shoji rail 7a are fitted into the concave grooves 2d provided in the upper sashes 2T of the two shoji windows 2. The two protruding strips 7y of the lower shoji rail 7b carry the outer circumferential surfaces of the rollers K, which are recessed in an approximately arc shape and attached to the lower sashes 2B of the two shoji windows 2.

In this way, the two shoji windows 2 are able to move left and right on the rails and are fitted into the opening W1 shown in Figure 1 between the upper horizontal frame 6 and the middle horizontal frame 4.

A roughly C-shaped hanger rail 8 is fixed to the underside 4b of the middle horizontal frame 4 so as to extend in the longitudinal direction of the middle horizontal frame 4 (depth direction of the page). There are no particular limitations on the method of fixing the hanger rail 8 to the underside 4b of the middle horizontal frame 4, but in this embodiment, it is fixed by a roughly C-shaped holding member 9 that holds the middle horizontal frame 4 and the hanger rail 8 together from above and below.

Two hanger rails 8 are fixed in parallel across the width of the middle horizontal frame 4 with the openings of the rail grooves 8a facing downwards, and are installed so that sliding doors 3 can be placed on either the inside S1 or outside S2 of the space (room, etc.) they partition.

A hanger roller 10 mounted inside the hanger rail 8 has two roller portions 10a that sandwich an axle, and a connecting shaft 10b that extends downward from the axle.
The hanger roller 10 is firmly fixed to the upper end surface 3 a of the sliding door 3 .

The sliding door 3 is mainly composed of a panel member 11 .
The panel member 11 is formed in a substantially rectangular plate shape having a predetermined thickness. Specifically, the panel member 11 is formed by arranging two thin surface materials 12, 12 facing each other on both sides in the thickness direction, and filling the space between them with a filling material 13 such as a paper core. A door stopper rubber (not shown) is attached to the door end side end surface of the panel member 11.

A metal reinforcing frame p1 is attached to the upper end 11a of the panel member 11, surrounding the front side (e.g., inside the room) S1, the top end face, and the back side (e.g., outside the room) S2, reinforcing almost the entire upper end 11a of the panel member 11.

The above components secure the hanger rail 8 to the underside 4b of the middle horizontal frame 4, and with the roller portion 10a of the hanger roller 10 attached inside the hanger rail 8, the sliding door 3 with the hanger roller 10 attached is suspended freely.

In this state, a cover member 20 is attached to the upper surface 4a of the middle horizontal frame 4, as well as the front side S1 and rear side S2 of the sliding door 3, covering the middle horizontal frame 4, the hanger rail 8, the hanger roller 10, and the upper end of the sliding door 3 in the vertical direction and almost the entire width direction of the sliding door 3.

As shown in FIG. 3, the cover member 20 is a member formed by bending a band-shaped plate member in the short direction into a substantially L-shape.
One side (the narrower portion in this embodiment) of the cover member 20 separated by the folding line L<b>1 constitutes a top wall portion 21 , and the other side (the wider portion in this embodiment) constitutes a side wall portion 22 .

As shown in FIG. 4 , the top wall portion 21 is disposed so as to cover the upper end surface 4 a of the middle horizontal frame 4 .
The short-side dimension of the top wall portion 21 (i.e., the dimension extending horizontally from the bending line L1) is formed with a width dimension slightly smaller than the length from the convex strip 7y to the upper edge 4t of the middle horizontal frame 4 closest to the convex strip 7y, so as not to interfere with the convex strip 7y provided on the upper surface 4a of the middle horizontal frame 4.

The top wall portion 21 has screw holes at appropriate intervals in its longitudinal direction (the direction of the bending line L1, that is, the extension direction of the middle horizontal frame 4) through which screws 24 can be inserted to fix the top wall portion 21 to the upper surface of the middle horizontal frame 4.

The side wall portion 22 is a portion that is arranged to cover the front side S1 and the back side S2 from the upper edge 4t of the middle horizontal frame 4 to the upper end of the sliding door 3, respectively.
The short-side dimension of the side wall portion 22 (i.e., the dimension extending approximately vertically from the bending line L1) is formed to a length dimension that extends from the upper edge 4t of the middle horizontal frame 4 to the upper end of the front (or back) of the sliding door 3, completely covering the gap S formed above the sliding door 3.
In addition, although not essential, in this embodiment, the lower edge of the side wall portion 22 is folded from the viewpoint of design and creating a smooth surface.

The cover member 20 having the above configuration is immovably fixed to the middle horizontal frame 4 by inserting screws 24 into the screw holes in the top wall portion 21, as shown in FIG. 5.

The central horizontal frame 4, the hanger rail 8, the hanger rollers 10, the sliding door 3, and the cover member 20 that covers these and closes the gap S above the sliding door 3 constitute the mounting structure 1 for the sliding panel.
A groove 25 that opens toward the floor surface F is formed in the lower end 11b of the panel member 11. A metal reinforcing frame p2 is fitted into the groove 25 along an inner surface 25a on the front side S1, a lower bottom surface 25b, and an inner surface 25c on the back side S2 to cover and reinforce substantially the entire groove 25.

A guide roller 26 is arranged in the groove 25 at the lower end of the panel member 11 and is fixed to the floor surface F on which the sliding parts of the two sliding doors 3 are located. The guide roller 26 is composed of a base portion 26a, a support shaft 26b that protrudes vertically from the base portion 26a, and a roller 26c that is rotatably mounted horizontally on the upper end of the support shaft 26b.

Next, a method for installing the slide door 3 using the mounting structure 1 for the slide panel of the present invention will be described.
<Panel mounting process>
First, the hanger rail 8 is fixed to the underside of the center horizontal frame 4, and the hanger roller 10 is attached to the hanger rail 6. The guide roller 26 is also fixed in advance to the floor surface F corresponding to the sliding portion of the sliding door 3.

Then, as shown in FIG. 4 , the hanger roller 10 is fixed to the upper end of the sliding door 3 , so that the sliding door 3 is mounted on the hanger rail 8 via the hanger roller 10 .
In addition, if the sliding door 3 can be hung by fixing a hanger roller 10 to the upper end of the sliding door 3 in advance and attaching the roller portion 10a of the hanger roller 10 to the hanger rail 8, this method may be adopted.

<Cover installation process>
Next, the top wall portion 21 is placed against the upper end face of the center horizontal frame 4, the side wall portion 22 is placed against the upper end of the sliding panel 3, and as shown in Fig. 5, the top wall portion 21 is screwed to the center horizontal frame 4, and the cover member 20 is attached from the center horizontal frame 4 to the upper end of the sliding door 3. The cover member 20 is also attached to the back side S2 of the sliding door 3 in the same manner as above.

The shoji window 2 can be installed at any time.

The above method makes it very easy to attach the cover member 20 to cover the gap S above the sliding door 3 without having to consider interference between the cover member 20 and other components.

This installation method can be achieved by having the cover member 20, which is attached from the horizontal frame to the upper end 3a of the sliding door 3, divided into one that covers the front side S1 and one that covers the back side S2.

In addition, by using this cover member 20, the gap S formed at the upper end of the sliding door 3 can be covered more reliably than before, and light leakage and drafts can be more effectively prevented.

In addition, by setting the short-side length of the side wall portion 22 to a certain extent, differences in dimensions of the middle horizontal frame 4, hanger roller 10, etc. can be absorbed, so that a limited number of sizes of cover members 20 can be used to accommodate hanging-type sliding doors 3 with different dimensional designs.

In the above embodiment, the cover member 20 is described as being L-shaped when viewed from the side, but the shape of the cover member 20 is not limited to being L-shaped when viewed from the side. In other words, the cover member 20 may be formed only from a flat plate member without a top wall portion 21, as long as an engaging portion is provided on the side wall portion 22, an engaged portion corresponding to the engaging portion is provided on the center horizontal frame 4, and the structure is such that the engaging portion is firmly engaged with the engaged portion by simply pushing the engaging portion into the engaged portion, making it impossible to remove.

Also, instead of the screw holes provided in the top wall portion 21 of the cover member 20, the above-mentioned engaging portion and engaged portion may be provided in the top wall portion 21 and the upper surface portion of the middle horizontal frame 4, respectively.
According to this configuration, it becomes very easy to attach the cover member 20 located at a relatively high position.

The side wall portion 22 of the cover member 20 does not necessarily have to be rectangular, and the lower edge of the side wall portion 22 may be formed in a wavy shape or other design shape as long as it can reliably cover the gap S at the top of the sliding door 3. This configuration has the effect of enhancing the design of the mounting structure 1 for the sliding panel with the cover member 20.
