JPH02104884A - Locked sliding door prevented from separation - Google Patents

Abstract

PURPOSE:To simply prevent the separation of sliding door by a method in which the upper end of locked sliding door is provided with a traveler running in the groove of a ceiling rail and a separation-preventing projection to fit with the notch of the ceiling rail when the door is removed, and whole of the sliding door is lifted up as it is locked. CONSTITUTION:The traveler 9 of two sliding doors 8 having two separation- preventing projections 10 is held on the traveling grooves 6 of a ceiling rail 1 having two notches to fit on the projections 10 on its back hanger and two notches 5 on its partition wall. Locking is made by a locker 14 attached to a vertical frame whose both sides are closed and both sliding doors are lapped on each other. By locking on one point in the place of the locker 14, the projections 10 collide with the back hang wall 3 even when two sliding doors 8 are lifted up to prevent the separation of the sliding doors.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a sliding door for a building or a sliding door for a cupboard.

[Prior art] Compared to hinged doors, sliding doors take up less space when opening and closing, and are extremely useful.However, when locking a sliding door, even if the sliding doors are closed and the vertical frames of overlapping doors are locked, the entire sliding door will not be locked. It is well known that it can be easily removed by lifting it up.

To prevent this, for example, in the case of two sliding doors, lock one on the left pillar and the other on the right pillar, or lock the sliding doors in one place in the middle. Attach sleeves to the left and right pillars and create two sliding doors! ! They had to be made so that they could not be removed while tied together.

However, these methods have disadvantages in that the former method is complicated to lock and unlock, and the latter method is undesirable because the sleeve portion poses a risk of collision when a person enters or exits or when items are taken in and out.

"The anti-removal locking sliding door described in paragraphs 1 to 5, which is provided with a protrusion 10."

[Example] The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a perspective view of the top rail 1 of the present invention, and numeral 4 in the figure is the top plate of the top rail. 2 is a front hanging wall that hangs down from the front part of the top plate. 3 is the rear hanging wall.

A partition wall 7 is installed between both hanging walls. A plurality of partition walls 7 may be provided.

A rail running groove 6 is formed between the hanging wall and the partition wall, and when a plurality of partition walls 7 are provided, the rail running groove 6 is also formed between the partition walls.

At least one of the front and rear hanging walls has a door removal prevention protrusion 1.
A cutout portion 5 that fits with the hole 0 is provided at least at one location.

FIG. 2 is a perspective view of a locking sliding door 8 provided with two anti-removal protrusions 10 that fit into notches 5 provided in the top rail 1, and 9 is a running portion that runs in the top rail running 7ri6. be.

Reference numeral 11 denotes a vertical frame of the door, and a detachment prevention protrusion 10 is provided to project from the upper end of the vertical frame.

12 is an upper horizontal frame. 14 is a locking part.

FIG. 3 shows a locking sliding door 13 that is not provided with a removal prevention protrusion.

The sliding door shown in FIG.
This is the structure between the sliding door and the road in the figure.

FIG. 4 is a perspective view of the door closed using the most standard locking sliding door of the present invention.

That is, the running portions 9 of the two sliding doors 8 each having two anti-removal protrusions 10 are provided with two notches 5 on the rear hanging portion and two on the partition wall that fit into the anti-removal protrusions 10. It shows a state in which the sliding doors are clamped in the running grooves 6 of the top rail 1, closed on both sides, and locked by the locking parts 14 attached to the overlapping vertical frames of both sliding doors.

It should be noted that a door roller is attached to the lower end of the sliding door 8, and it goes without saying that the door roller runs on a conventionally known platform rail, so illustration thereof is omitted.

In this way, by locking one of the 14 locations,
Even if the two sliding doors 8 are lifted up, the projections 10 abut against the rear hanging wall and the sliding doors will not come off.

In this figure, two sliding doors are provided with protrusions to prevent removal, but even if one of the two sliding doors is replaced with a sliding door without a protrusion to prevent removal, as shown in FIG. can be achieved.

Furthermore, by increasing the number of rails, three or more sliding doors can be used.

In this case, at least one sliding door must have a protrusion to prevent removal.

Figure 5 shows how to lift the sliding door with the anti-removal protrusion and remove the protrusion 1.
0 is a perspective view showing a state in which the sliding door 8 is removed by fitting the door into the notch 5 provided in the rear hanging wall of the top rail.

The protrusion 10 fits into the notch 5 and allows the entire door to be lifted. If you lift it up and pull it towards you, the door will come off.

FIG. 6 shows the removal prevention protrusion 10 attached to the upper horizontal frame 12 of the sliding door.
It is a perspective view which shows the state where one is arrange|positioned on top.

One or more protrusions may be provided.

Although the protrusion is shown as a square prism in FIG. 6, it may of course be a cylinder, other square prism, or sphere.
The upper edge may be chamfered.

FIG. 7 is a perspective view showing a state in which the removal prevention protrusion 10 is disposed so as to protrude horizontally from the side surface of the running portion 9 of the sliding door.

Of course, one or more protrusions may be provided.

In FIG. 7, the protrusion 10 is shown as a square bar, but it goes without saying that it may be a round bar, any other bar, or a ball. The ridge portion may be chamfered to facilitate fitting into the notch portion 5.

FIG. 8 is a sectional view showing the relationship between the top end of a conventional sliding door and a top rail.

FIG. 9 is a sectional view showing a state in which the running portion of the sliding door of the present invention is held between the running grooves of the top rail.

As is clear from both figures, even if the thickness of the sliding door is the same, the width d of the top rail used in the present invention is not half the width of the conventional top rail, but it is extremely narrow. be able to.

This means that in storage partition furniture as shown in FIG. 10, when sliding doors, open shelves, drawers, Kannon circles, etc. can be freely replaced, the narrow width of the top rail is extremely advantageous.
