Description

The present invention relates to a sliding door opening / closing device, and more particularly to a sliding door opening / closing device provided with a self-closing mechanism.

Conventionally, various types of sliding door opening / closing devices have been provided in which the rails provided on the upper part of the sliding door frame are supported by the suspension vehicles provided on the door end side and the door tail side of the upper end of the sliding door so as to be able to run. Then, as shown in Patent Document 1, there is provided a sliding door incorporating a self-closing device that can always apply a constant closing force to automatically close the sliding door. On the other hand, as shown in Patent Document 2, when the sliding door is opened from the fully closed state to a position of a certain distance, elastic force in the closing direction is accumulated, and the sliding door that has moved from the open state to the closing direction is moved from the position of a certain distance. There is also one that incorporates a retracting device that supports the closing operation by the accumulated elastic force up to the fully closed state.

Although these self-closing devices and retracting devices each have advantages, a sliding door opening / closing device incorporating both of them has not been provided so far. The reason is that in the initial operation section where the sliding door is opened from the fully closed state, the load of the pull-in device and the self-closing device overlap, so a large opening force is required in that section, which is not easy to use and the user is very heavy. feel.

Therefore, in view of the above situation, the present invention attempts to solve the problem by incorporating both a retracting device and a self-closing device, and while demonstrating the advantages of each, the initial opening force in the initial operating section in which the sliding door is opened from the fully closed state. The point is to provide a sliding door opening / closing device that can open the sliding door even if it is small.

The present invention provides a sliding door opening / closing device having the following structure in order to solve the above-mentioned problems.

(1)
A self-closing device that applies a closing force to the sliding door in the closing direction, and a sliding door that accumulates elastic force in the closing direction when opening the sliding door from the fully closed state to the position of the operating distance L, and moves from the open state to the closing direction. A sliding door opening / closing device equipped with a retracting device that supports the closing operation by the accumulated elastic force from the position of the operating distance L to the fully closed state.
A delay mechanism is provided between the self-closing device and the sliding door so that the closing force of the self-closing device does not act when the sliding door is opened from the fully closed state to the position of the non-operating distance D, and the sliding door is not operated from the operating distance L. A sliding door opening / closing device characterized in that the distance D is set short.

(2)
In the delay mechanism, a linking member is arranged in the moving direction of the sliding door, a guide groove extending in the moving direction of the sliding door is formed in the linking member, and an operating pin fixed to the sliding door is not activated in the guide groove. The structure is such that the linking member can be relatively slidable by a distance D, the linking member is connected to the operating portion of the self-closing device, and the closing force is transmitted to the sliding door via the linking member. The sliding door opening / closing device according to (1), wherein the pin is located at the door end side end in the guide groove.

(3)
In the self-closing device, a constant load winding spring is fixed to a sliding door frame, an end portion of the operating portion made of a wire drawn from the constant load winding spring is connected to the linking member, and a non-operating distance D from the fully closed state. The sliding door opening / closing device according to (2), which has a structure in which a constant closing force is always transmitted to the sliding door through the linking member except for the position of.

(4) The rails provided on the upper part of the sliding door frame support the suspension vehicles provided on the door end side and the door tail side of the upper end of the sliding door so as to be able to travel, and the pulling device is arranged in the groove of the rail and described as described above. The sliding door opening / closing device according to (2) or (3), wherein the linking member constituting the delay mechanism is arranged between the upper end of the sliding door and the rail.

The sliding door opening / closing device of the present invention as described above has the following effects.

According to the configuration of (1), since the retracting device and the self-closing device are used together, both devices can be linked to automatically bring the opened sliding door into the fully closed state, and the sliding door can be opened from the fully closed state. At that time, the self-closing device can be delayed by the delay mechanism to the position of the non-operating distance D, so that the sliding door can be opened lightly. In other words, when the sliding door is opened from the fully closed state, elastic force in the closing direction is accumulated in the retracting device, but the sliding door accelerates to some extent while opening by the non-operating distance D, so by using this inertial force, It is possible to pass through a section where the load of the pull-in device and the self-closing device overlap and the opening force is heavy, and after that, only the load of the self-closing device is applied, so that the user does not feel heavy. On the other hand, when closing the sliding door from the fully open state or the halfway open state, if the handle of the sliding door is released, the sliding door automatically moves in the closing direction due to the closing force of the self-closing device, but the pull-in device is activated. Immediately after that, the closing force of the self-closing device does not work, so it can be slowly closed to the fully closed state. Here, if the retracting device is provided with a damper function, the sliding door accelerated by the self-closing device is decelerated and closed with the operation of the retracting device, so that the impact at the time of fully closing can be further softened. Further, the present invention is particularly effective when the sliding door is a heavy glass sliding door or the like.

According to the configuration of (2), a delay mechanism is provided so that the closing force of the self-closing device does not act when the sliding door is opened from the fully closed state to the position of the non-operating distance D by simply adding the linking member and the operating pin. Can be prepared.

According to the configuration of (3), a constant closing force can always be transmitted to the sliding door through the linking member except from the fully closed state to the position of the non-operating distance D.

According to the configuration of (4), no special space is required for arranging the linking members constituting the delay mechanism, and the sliding door only needs to be fixed with an operating pin at the upper end, and the existing sliding door opening / closing device can be used. It can be easily incorporated with minimal design changes.

Of course, instead of the door pocket panel 3, a second sliding door may be provided, and both sliding doors may be provided so as to be able to slide from each other.

The sliding door frame 2 is a gate type and has a structure in which an upper frame 8 is laid between the upper ends of the door end side frame 6 and the door tail side frame 7, and a rail is provided in a space 9 which is open downward of the upper frame 8. 10 is built-in. The rail 10 is a long member having a substantially C-shaped cross section having an opening groove in the central portion of the lower surface, and is provided over the substantially entire length of the upper frame 8 except for the end portion on the door end side.

The sliding door 1 holds a glass plate 15 between the upper and lower ends of the vertical frame 11 on the door end side and the vertical frame 12 on the door end side, and the upper frame 13 and the lower frame 14 are connected to each other. The vertical frame 11 on the door end side is provided with handles 16 and 16 on both the front and back sides. Since the sliding door 1 of the present embodiment is a glass sliding door and is heavy, it requires a larger closing force for self-closing than a normal sliding door. Therefore, it is important for usability to reduce the initial opening force. ..

In the sliding door frame 2, the door tip side frame 6 and the door tail side frame 7 are fitted to the columns 17 and 17 erected from the floor surface F to the ceiling S, and fixed by screws, and the ceiling S and the upper frame are fixed. The inter-column panel 4 is mounted between the column 8 and the wall panels 5 and 5, respectively, via the columns 17 and 17. Here, since the normal partition panel is used for the inter-column panel 4 and the wall surface panel 5, the details will be omitted.

Then, the suspension wheels 18 and 18 provided on the door tip side and the door tail side of the upper end of the upper frame 13 of the sliding door 1 are supported on the rail 10 so as to be travelable, and on the lower surface side of the lower frame 14 of the sliding door 1. A guide roller 20 having a vertical rotation axis protruding from the floor surface F corresponding to the door tail side of the sliding door 1 in the fully closed state is received in the concave groove 19 provided along the groove, and the lower portion of the sliding door 1 in the suspended state is received. Is stably guided to open and close.

In the door pocket panel 3, one side edge portion of the glass plate 21 is held by the door tail side frame 7, the upper edge portion is held by the upper frame 8, and the lower edge portion of the glass plate 21 is held by the floor surface F. The other side edge portion is supported by the vertical frame member 23, and the vertical frame member 23 is erected between the floor surface F and the upper frame 8, and the upper and lower end portions are supported by the ground rail member 22 laid in the floor. It is connected to the upper frame 8 and the ground rail member 22.

Further, a door stop member 24 made of an elastic material is provided at the end of the vertical frame 11 on the door end side of the sliding door 1, and the door stop member 24 is received on the side surface of the door end side frame 6 to provide airtightness. A cushion member 26 for forming a joint groove 25 to be raised and further stopping the vertical frame 12 on the door tail side when the sliding door 1 is fully opened is attached to the side surface of the door tail side frame 7.

As shown in FIGS. 5 to 11, the sliding door opening / closing device according to the present invention includes a self-closing device A that applies a closing force to the sliding door 1 in the closing direction, and the sliding door 1 from a fully closed state to a position of an operating distance L. It is provided with a retracting device B that accumulates elastic force in the closing direction when opening and supports the closing operation of the sliding door 1 that has moved from the open state to the closing direction from the position of the operating distance L to the fully closed state by the accumulated elastic force. In the sliding door opening / closing device, the closing force of the self-closing device A does not act when the sliding door 1 is opened from the fully closed state to the position of the non-operating distance D between the self-closing device A and the sliding door 1. The delay mechanism C is provided in the vehicle, and the non-operating distance D is set shorter than the operating distance L.

Specifically, as shown in FIGS. 5 and 11, the delay mechanism C arranges the linking member 27 in the moving direction of the sliding door 1, and guides the linking member 27 extending in the moving direction of the sliding door 1. A groove 28 is formed so that the operating pin 29 fixed to the sliding door 1 can be relatively slidably moved in the guide groove 28 by the non-operating distance D, and the linking member 27 is attached to the operating portion 30 of the self-closing device A. The structure is such that the closing force is transmitted to the sliding door 1 via the linking member 27, and the operating pin 29 is positioned at the door end side end in the guide groove 28 in the fully closed state. The non-operating distance D is the distance at which the operating pin 29 moves from the door end side end to the door tail side end in the guide groove 28.

More specifically, as shown in FIG. 7, the linking member 27 is a long member having a substantially U-shaped cross section in which the main body portion excluding the door end side is open on the side surface, and two pairs are formed on the lower surface plate 31 along the longitudinal direction. The elongated holes 32 and 32 are formed, and the slide members 33 having the guide grooves 28 formed in the elongated holes 32 are screwed and fixed in the fitted state, respectively, and the self-closing device is attached to the end on the door end side. A connecting hole 34 for connecting the operating portion 30 of A is formed, and is arranged in the opening / closing direction along the upper surface of the upper frame 13 of the sliding door 1. On the other hand, on the upper surface of the upper frame 13 of the sliding door 1, the mounting pedestals 35 for mounting the suspension wheel 18 are fixed by screws on the door tip side and the door tail side, respectively, and are between the two mounting pedestals 35 and 35. Therefore, the operating pin 29 is projected upward so as to correspond to the guide grooves 28 and 28. The actuating pin 29 has a bush 36 having a shaft portion 36A inserted into the guide groove 28 of the slide member 33 and a flange portion 36B locked to the upper edge of the guide groove 28 with mounting screws 37 to form an upper frame of the sliding door 1. It is screwed and attached to the upper surface of 13. The linking member 27 constituting the delay mechanism C is arranged between the upper end of the sliding door 1 and the rail 10, and the upper part of the upper frame 13 of the sliding door 1 is the space 9 of the upper frame 8 of the sliding door frame 2. Since it is located inside, the linking member 27 is in a position that cannot be directly viewed.

Here, in the self-closing device A, the constant load winding spring 38 is fixed to the sliding door frame 2, and the end portion of the operating portion 30 made of the wire 39 drawn from the constant load winding spring 38 is connected to the linking member 27. It is a structure that is connected to the hole 34 and always transmits a constant closing force to the sliding door 1 through the linking member 27 except from the fully closed state to the position of the non-operating distance D. Since the constant load winding spring 38 has a known structure in which the wire 39 is always wound with a constant load, detailed description thereof will be omitted. The constant load winding spring 38 is fixed in the space 9 of the upper frame 8 in which the rail 10 does not exist. In the section where the sliding door 1 is started to be opened and the non-operating distance D is set, the operating pin 29 moves from the door tip portion to the door tail end portion of the guide groove 28 of the slide member 33, and no load is applied. Then, after the actuating pin 29 reaches the door tail end of the guide groove 28 of the slide member 33, the actuating pin 29 and the slide member 33 move integrally in the opening / closing direction, and the constant load is applied. The wire 39 is pulled out from the winding spring 38 under a constant load. On the contrary, when the sliding door 1 is moved in the closing direction, the pulling force of a constant load of the constant load winding spring 38 is transmitted to the sliding door 1 via the wire 39, the slide member 33 and the operating pin 29, and the sliding door 1 is described. The sliding door 1 is moved in the closing direction until the wire 39 is pulled into the constant load winding spring 38. The state in which the closing force by the constant load winding spring 38 is no longer generated is a state in which the sliding door 1 is still open by the non-operating distance D. In the present invention, it is also possible to use a normal winding spring instead of the constant load winding spring 38. At that time, it is preferable to adopt a constant load winding spring 38 or a normal winding spring whose load strength can be adjusted.

As described above, the retracting device B accumulates elastic force in the closing direction when opening the sliding door 1 from the fully closed state to the position of the operating distance L, and operates the sliding door 1 that has moved from the open state to the closing direction. It is a known structure that supports the closing operation by the accumulated elastic force from the position of the distance L to the fully closed state.
It is arranged in the groove of the rail 10. Normally, the suspension wheel 18 on the door end side is integrated with the pull-in device B, and is incorporated inside a rod 40 extending from the main body of the suspension wheel 18 to the door tail side, and the door of the rod 40 The rolling wheel 41 provided at the tail end moves in the rail 10 and maintains its posture.

Here, the working distance L is determined by the position of the trigger 42 fixed in the rail 10. When the sliding door 1 is opened from the fully closed state, the operating portion of the pulling device B locked to the trigger 42 is displaced, the tension coil spring of the pulling device B is stretched to accumulate elastic force, and the trigger 42 is accumulated. After moving a predetermined distance (operating distance L) with respect to the above, the operating portion is disengaged from the trigger 42 and locked in an appropriate position of the rod 40, and the sliding door 1 maintains a state in which elastic force is accumulated in the tension coil spring. It will be released. Then, when the sliding door 1 is closed, when the sliding door 1 moves in the closing direction and the operating portion comes to the position of the trigger 42, the operating portion is disengaged from the rod 40 and at the same time locked to the trigger 42. The accumulated elastic force of the tension coil spring is opened to the trigger 42 as a fulcrum to support the closing operation of the sliding door 1 until it is fully closed.

In the sense of supporting the closing of the sliding door 1, the self-closing device A and the pull-in device B need to have a load acting on the sliding door 1 seamlessly. Therefore, the non-operating distance D is set shorter than the operating distance L, and a section where the loads of the self-closing device A and the pulling device B overlap is provided. However, it is advantageous to make the combined section as short as possible in order to reduce the initial opening force. Therefore, in the present embodiment, the working distance L is set to 117 mm and the non-working distance D is set to 110 mm, but in consideration of an error, practically, [working distance L]-[non-working distance D] ≤ 10 mm. It is preferable to set so as to be.

The operations of the self-closing device A, the pull-in device B, and the delay mechanism C during the opening / closing operation of the sliding door 1 will be briefly described with reference to FIGS. 5 to 10. First, when the sliding door 1 is opened from the fully closed state, an elastic force in the closing direction is accumulated in the retracting device B, but the sliding door 1 delays the start of the load of the self-closing device A in the non-operating distance D section. Since it can be delayed by C, some acceleration is applied while the non-operating distance D is opened. By utilizing the inertial force of the sliding door 1, it is possible to pass a section with a heavy opening force (a section between the non-operating distance D and the operating distance L) in which the loads of the pulling device B and the self-closing device A overlap, and then the section is passed. Is only the load of the self-closing device A, so that the user does not feel heavy. On the other hand, when closing the sliding door 1 from the fully opened state or the halfway opened state, if the hand is released from the handle 16 of the sliding door 1, the sliding door 1 automatically moves in the closing direction due to a constant closing force by the self-closing device A. However, since the closing force of the self-closing device A does not act immediately after the pulling device B is activated, the retracting device B can slowly close to the fully closed state only by the accumulated elastic force.

12 and 13 are layouts in which the connecting direction of the wall surface panel 5 is set at a right angle to the sliding door frame 2. FIG. 12 has a structure in which the door end side frame 6 is connected to the end cover 44 of the wall surface panel 5 at a right angle via a narrow connecting column 43 instead of the column 17.
