Description

Description: [Industrial field of use] The present invention relates to a temporary stop device for a self-closing sliding door, in particular a top-hung self-closing sliding door.

[Prior Art] In a self-closing sliding door, when carrying luggage in and out by a dolly, or when it is desired to keep the sliding door open by an opening width necessary for people to enter and leave the room, or There are cases where it is desired to stop the sliding door at the required opening position, such as when opening the sliding door slightly to ventilate or ventilate the room. As a device that satisfies such a demand, there is a temporary stop device for a self-closing sliding door.

Hereinafter, a conventional temporary stop device will be described with reference to FIGS. 9 to 11.

First, FIG. 9 and FIG. 10 show the external attachment method.
Is a sliding door, and 2 is a suspension device.

A rod 4 having a rubber seat 3 attached to its lower end is provided slidably in the vertical direction, and the rod 4 is biased upward. When the pedal 5 is stepped on, the rod 4 is pressed downward via the spring 6, the rubber seat 3 is pressed against the floor 7, and the pressed state is maintained. When the pedal 5 is further pressed, the pressed state is released. It has become like.

Thus, the temporarily stopped state of the sliding door 1 is realized by the frictional force when the rubber seat 3 is pressed against the floor 7.

Next, FIG. 11 shows a conventional example of a built-in system.

A push rod 8 is provided inside the sliding door 1 slidably in the vertical direction via a bearing block 9, and a rubber cap 10 is fitted to the upper end of the push rod 8. The push rod 8 is biased upward by a compression spring 11. A lock pin 12 is provided on the push rod 8 in a protruding manner, and the lock pin 12 is slidably fitted in a guide hole 13 whose lower end is bent like a fishhook.

Reference numeral 14 in the figure is a guide rail for hanging. When the sliding door 1 is opened and closed, as shown in the drawing, the lock pin 12 is pulled down,
It is hooked on the curved portion of the guide hole 13 and the push rod 8 is pulled downward so that the rubber cap 10 and the guide rail 14 are separated from each other. When the lock pin 12 is removed from the curved portion of the guide hole 13 when temporarily stopped, the push rod 8
Is pushed up by the compression spring 11 and the rubber cap
10 is pressed against the guide rail 14. Thus, due to the frictional force between the guide rail 14 and the rubber cap 10, the sliding door 1
Is suspended.

[Problems to be Solved by the Invention] However, of the conventional temporary stop devices described above, those of the external type are exposed and unfavorable in appearance. Since it is a stepping operation, it can be performed while standing, but it is difficult to do because of an unstable posture such as when carrying luggage. Since the braking force differs depending on the material of the floor and the floor is not completely flat, a sufficient braking force may not be obtained depending on the temporary stop position.

Further, in the case of the built-in system, friction is generated on the guide rails, so braking is reliable, but from the state of temporary suspension, the brake may not be released from the device, and opening and closing operations may be mistakenly performed. However, in the case of the above-mentioned built-in method, there is a risk of damage.

In view of the above situation, the present invention is to provide a temporary stop device that is a built-in type that ensures braking without damaging the appearance and that is not damaged by an erroneous operation.

[Means for Solving the Problem] The present invention provides a connecting rod slidably in a vertical direction inside an upper sliding door and urges the connecting rod downward, and at the lower end of the connecting rod, a knob exposed to the outside of the sliding door is provided. A housing is provided at an upper end portion, and an oscillating body that can be pressed against a guide rail of the sliding door is provided on the housing so as to be swingable in the sliding door moving direction and slidable in the rod axis direction. The clutch pin is fitted into the rocking body and is connected through a shortenable connecting pin, and the connecting pin is movable in the horizontal direction, and the connecting pin is engaged with a clutch groove engraved on the inner surface of the housing. A locking projection is provided on the locking pin, and the connecting pin is engaged with the locking projection at a raised position, and the rocking of the rocking body causes the connecting pin and the locking projection to be disengaged from each other. Is.

[Operation] When the knob is pushed upward, the rocking body rises via the connecting rod and the connecting pin and presses against the guide rail to exert a braking force. The connecting pin engages with the locking protrusion at the raised position, restricts the descent of the rocking body, and maintains the braking state. Next, when the sliding door is swung, the swinging body swings, the connecting pin and the locking projection are disengaged, the swinging body and the connecting rod descend, and the braking state is released.

The housing 31 is fitted on the upper end of the sliding door 1, and the upper end of the connecting rod 19 is inserted into the lower end of the hollow housing 31.

The hollow part 32 of the housing 31 has a rectangular plane cross section, and an edge part 33 is provided in the vicinity of the upper end of the hollow part 32 so as to project on two surfaces orthogonal to the moving direction of the sliding door 1. ing. A bracket 34 having a concave cross-section in a plane orthogonal to the moving direction of the sliding door 1 is slidably fitted on the lower side of the hollow portion 32, which is partitioned by the edge portion 33, and the bracket 34 is slidably fitted to the hollow portion 32.
34 is screwed to a screw portion 35 provided on the upper end of the connecting rod 19. Further, a long hole 36 having a long axis extending horizontally is formed in the bracket 34, and a connecting pin 37 is slidably fitted in the long hole 36.

An oscillating body 38 is fitted from above the housing 31, and the connecting pin 37 is fixed to the lower end of the oscillating body 38. The oscillating body 38 has a rectangular cross section in plan view, and two surfaces of the oscillating body 38 parallel to the moving direction of the sliding door 1 are in sliding contact with the inner surface of the housing 31, and the other two surfaces of the oscillating body 38. A gap is formed between the housing 31 and the inner surface of the housing 31 by the protruding height of the edge portion 33.

Thus, the rocking body 38 can rock around the apex of the edge portion.

Further, the rocking body 38 includes a reverse body portion 39 to which the connecting pin 37 is fixed, a cylinder body 40 fixed to an upper end of the reverse body portion 39, and a braking spring 41 fitted to the cylinder body 40. A rubber cap 42 is fixed to the head of the cylinder 40, and the brake element 43 is slidably fitted to the cylinder body 40. The brake spring 41 is given a required initial deflection. Stop means are provided.

The braking portion 18 has a clutch groove 44 formed on a surface of the housing 31 parallel to the moving direction of the sliding door 1 of the housing 31.
A lock mechanism composed of and is provided.

The connecting pin 37 is biased in a separating direction by a spring 37c held by pin segments 37a and 37b, and an end portion thereof is attached to a bracket 34
It projects further and is constantly pressed against the bottom surface of the clutch groove 44.

The shape of the clutch groove 44 will be described with reference to FIGS.

The clutch groove 44 includes a locking projection 45 at the center, a downward return shallow groove 47 formed around the locking projection 45 and both sides thereof, and an ascending guide deep groove 47 provided below the locking projection 45. Becomes
The bottom surface of the ascending guide deep groove 47 and the apex of the locking projection 45 are connected by a slope 48 that gradually rises.
The lower surface of the descending return shallow groove 46 is an inclined surface 49 facing the ascending guide deep groove 47.

Thus, the connecting pin 37 slides in the clutch groove 44, and the cooperation of the swinging of the oscillating body 38 and the ascending / descending of the connecting rod 19 enables braking and braking release. There is.

The operation will be described below.

When the sliding door 1 is in the open / closed state (non-braking state), the connecting rod 19 is pushed downward by the compression spring 29, and the connecting pin 37 is at the lower end of the ascending guide deep groove 47. The state of FIG. 2 shows a braking state.

Next, when the sliding door 1 is braked at a desired position, the knob 27 is pushed upward and the connecting rod 19 is raised via the slider 26 (state shown in FIG. 2).

When the connecting rod 19 rises, the rocking body 38 is lifted via the bracket 34 and the connecting pin 37, and the rubber cap 42 of the brake element 43 eventually contacts the lower surface of the guide rail, and the braking spring
41 is more flexible.

Further, the connecting pin 37 is guided by the ascending guide deep groove 47,
It rides on the slope 48, rises while being gradually shortened, and finally climbs over the top of the locking projection 45. When the connecting pin 37 crosses over the locking protrusion 45, it is projected by the repulsive force of the spring 37c, and the connecting pin 37 and the locking protrusion 45 are brought into an engaged state.

Therefore, even if the knob 27 is released and no upward force is applied, the slider 26,
The raised position of the connecting rod 19 is maintained.

Further, in the engaged state of the connecting pin 37 and the locking projection 45, the brake element 43 contacts the guide rail 14, and the braking spring 41
Since the flexure is in a bent state, a braking force is generated between the rubber cap 42 and the guide rail 44, and the sliding door 1 is temporarily stopped.

Next, in order to release the braking state, a force in the opening or closing direction may be further applied to the sliding door 1.

When a force in the opening or closing direction is further applied to the sliding door 1, a large frictional force acts between the rubber cap 42 and the guide rail 14, so that there is no relative movement between the rubber cap 42 and the guide rail 14, and there is shaking. A horizontal force is applied to the moving body 38 via the edge portion 33, so that the moving body 38 swings around the top surface of the rubber cap 42.

The connecting pin 37 is moved in the horizontal direction by the swing of the swinging body 38, and is disengaged from the locking projection 45.

Since the connecting rod 19 is urged downward by the compression spring 29, the rocking body 38 descends via the connecting rod 19 and the bracket 34, and the connecting pin 37 also descends the descending return shallow groove 46, and further the inclined surface. It is led to the ascending guide deep groove 47 along 49.

Thus, the braking state is released.

As described above, in the temporary stop state of the present embodiment, when the brake is applied, only the knob is lifted, and when the brake is released, the hanging door is moved in either the opening or closing direction.

In order to swingably and slidably support the oscillating body 38 in the housing, the edge portion is not provided so that a groove extending in the axial direction is provided on two surfaces of the oscillating body 33 parallel to the opening / closing direction of the hanging door. , Housing 31
A pin that slidably fits in the groove may be provided on the inner surface of the protrusion. Alternatively, a groove may be formed on the housing side, and a pin may be projected on the oscillator.

[Effects of the Invention] As described above, according to the present invention, the guide rail is braked, which is reliable, and the braking can be performed only by pushing up the knob, and the braking can be performed by moving the hanging door. It is very simple, and in particular, since the brake release is performed by moving the sliding door in either the opening or closing direction, the excellent effect that there is no damage due to an erroneous operation can be exerted.
