Description

  The present invention relates to an apparatus for preventing rebound of an interlocking sliding door that can prevent the interlocking sliding door provided at an opening of a building, such as an assembly stand, from rebounding when the door is opened and closed, or being naturally opened.

Conventionally, an interlocking type sliding door provided at an opening of an assembly stand or the like is provided with a door at the upper part, and this door is movably suspended on a hanger rail on the upper frame of the opening, thereby reducing the frictional resistance of the sliding door. It can be opened and closed smoothly. However, because the sliding of the sliding door is too good, when it is closed vigorously, the sliding door may hit the pillar of the opening and bounce back to a half-open state or open naturally.
As a countermeasure against this, there is one with a latch mechanism that can automatically temporarily lock when the sliding door is closed. Also, a recess is provided in a part of the rail of the sliding door, and when the sliding door is closed, the door wheel falls into the recess and stops, or a protrusion is provided in a part of the rail, and the door wheel protrudes immediately before the sliding door is fully closed. There are those that have been passed over the section (for example, see Patent Document 1).

JP 2001-146850 A

  However, in the case where the latch mechanism is attached to the sliding door, the structure is complicated and the cost is increased, and the dimensional accuracy of the member is required. In addition, when the sliding door is closed and the door wheel falls into the recess of the rail and stops, the sliding door tilts slightly when fully closed, and this tilt creates a gap. When the door is over the convex part of the rail just before the sliding door is fully closed, there is a problem that the sliding door is slightly inclined immediately before the sliding door and the smoothness of the fully closing operation is lacking. Furthermore, in the case where the door opens over the convex part of the rail just before the sliding door is fully closed, the sliding door is unintentionally opened. There is a problem of losing.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide an interlocking sliding door using an interlocking roller, and by using the interlocking roller, a simple means can be used for the interlocking sliding door. An object of the present invention is to provide a bounce prevention device for an interlocking sliding door that can prevent bounce.

The present invention includes two hanger rails provided inside an upper frame having inner and outer wall portions of a building opening, two inner and outer sliding doors arranged inside and outside the upper frame, and inner and outer sliding doors. A belt-shaped door wheel plate attached to each upper part, a door wheel attached to each door wheel plate, suspended movably on each hanger rail, and attached to the upper part of the inner sliding door, with a peripheral surface An interlocking type sliding door comprising a interlocking roller that is in sliding contact with the door plate of the outer sliding door and that is slidably contacted with the inner wall portion of the upper frame and is horizontally rotatable about the vertical axis. the upper frame roller is mounted swingably in and out direction perpendicular to the rocking axis, which corresponds to one longitudinal end of the longitudinal end or該戸car plate door roller plate of the outer sliding door The longitudinally intermediate portion of the inner wall portion, provided with a concave portion into which the interlocking rollers fully closed outer sliding door is depressed engaging the circumferential surface portion of the interlocked roller swings about the oscillation axis It has a feature in being.

In this case, the outer sliding door is also fully opened on the other end side in the longitudinal direction of the door plate of the outer sliding door or on the end portion in the longitudinal direction of the inner wall portion of the upper frame corresponding to the other end side in the longitudinal direction of the door wheel plate. In some cases, a recessed portion in which a part of the peripheral surface of the interlocking roller falls and engages can be provided.
In addition, the interlocking roller is swingable inward and outward about a swing axis between the door wheel plate of the outer sliding door and the inner wall portion of the upper frame, and always has the recessed portion. A spring that is pressed and urged against the frame can be provided.

  When the outer sliding door is fully closed, a part of the peripheral surface of the interlocking roller is provided at the longitudinal end of the inner frame of the upper frame corresponding to one longitudinal end of the door sliding plate of the outer sliding door or one longitudinal end of the door sliding plate. The sliding door can be prevented from bouncing back by engaging with the recessed portion.

  When providing the concave portion on one end side in the longitudinal direction of the door plate, it can be processed easily and at a low cost by simply stepping the one end side in the longitudinal direction when the door plate is pressed.

  Because the door roller plate or upper frame with which the interlocking roller is in sliding contact is provided with a recess, the sliding door tilts and creates a gap when it is fully closed, as in the conventional case where a recess or protrusion is provided on the rail itself on which the door wheel rolls. There is no problem that the sliding door tilts immediately before full closing and the smoothness of the full closing operation is lacking, and the sliding door can be fully closed without tilting.

When the outer sliding door is fully opened, a part of the peripheral surface of the interlocking roller falls on the other end in the longitudinal direction of the door plate of the outer sliding door or on the end in the longitudinal direction of the upper frame corresponding to the other end in the longitudinal direction of the door plate. By providing the engaging recesses, the sliding door can be prevented from rebounding both when the sliding door is fully closed and when it is fully opened.
The interlocking roller can be swung in and out around the swing axis between the door wheel plate of the outer sliding door and the inner wall of the upper frame, and is always pressed against the door wheel plate or upper frame having a recessed portion. By providing the spring to be biased, the interlocking roller can be surely dropped into the recess.

  1 and 2, 1 is an assembly-type storeroom, 2 is a column erected at the four corners of the storeroom 1, 3 is an intermediary column erected between the columns 2 and 2, 4 is a left side surface of the storeroom 1, not shown 5 is a roof panel, 6 is an opening in the front of the storage 1, 7 is an upper frame of the opening 6, 8 is a lower frame of the opening 6, and 9 is an opening. 6 is an interlocking type sliding door composed of inner and outer sliding doors 9a and 9b arranged inside and outside between the upper and lower frames 7 and 8, and the inner and outer sliding doors 9a and 9b are fixed to the right end of the opening 6 in a fully opened state. It is stored in the front side of the wall 10 (see FIG. 8B).

  Next, an interlocking mechanism that moves the inner sliding door 9a in conjunction with the movement of the interlocking sliding door 9 and the outer sliding door 9b will be described with reference to FIGS. 2, 3A, and 3B. Two inner and outer hanger rails 11 and 12 are fixed in the left and right direction inside the groove of the upper frame 7 having a groove shape in the opening 6 and having inner and outer wall portions 7a and 7b. On the rear surfaces of the upper portions of the inner sliding door 9a and the outer sliding door 9b, the lower ends in the width direction of the belt-shaped door wheel plates 13 and 14 are respectively attached over the respective sliding door width directions. At the upper end in the width direction of each door wheel plate 13, 14, door wheels 15, 16 movably suspended on the inner and outer hanger rails 11, 12 are rotatably supported. In addition, each lower end part of the sliding doors 9a and 9b is moved and guided in the left-right direction by a lower rail (not shown) disposed on the lower frame 8.

As shown in FIGS. 2, 3 (a) and 3 (b), an interlocking roller 18 that can rotate horizontally around the vertical axis 17 is attached to the upper portion of one side in the width direction of the inner sliding door 9 a. Of the outer sliding door 9b is installed so as to be in sliding contact with the sliding contact portion 141 on the rear surface of the intermediate portion in the width direction of the door plate 14 and the sliding contact portion 71 on the front surface of the inner wall portion 7a of the upper frame 7.
As shown in FIGS. 2, 3 (a) and 3 (b), the interlocking roller 18 protrudes from the vertical cylinder 19 of the vertical axis 17 supported so as to be always pushed up and biased by the spring 20 in the vertical cylinder 19. Attached to the upper end. As shown in FIGS. 3 (a) and 3 (b), the vertical cylinder 19 has an overhanging portion 19a protruding from a part of its circumference, and this overhanging portion 19a is fixed to the upper portion of one side surface of the inner sliding door 9a. A swinging shaft 22 perpendicular to the bracket 21 is swingably mounted inward and outward.

  As shown in FIG. 2, the sliding contact portion 141 of the door wheel plate 14 of the outer sliding door 9b and the sliding contact portion 71 of the inner side wall portion 7a of the upper frame 7 are narrowed in the upward direction. It is formed on an inclined surface. Since the interlocking roller 18 is always pushed up and biased by the spring 20 as described above, the peripheral surface of the interlocking roller 18 is the sliding contact portion 141 of the door wheel plate 14 and the sliding contact portion of the inner wall portion 7a of the upper frame 7. 71, the interlocking roller 18 is always pressed against the sliding contact portion 141 of the door wheel plate 14 of the outer sliding door 9b and the sliding contact portion 71 of the inner wall portion 7a of the upper frame 7. There is no need to adjust even if the dimensions between the sliding contact portions 141 and 71 change slightly due to variations in processing and assembly, and the sliding doors 9a and 9b do not rattle.

  Thus, the interlocking type sliding door 9 provided with the interlocking roller 18 has the outer sliding door 9b as shown in FIG. 8C from the fully closed state of the sliding doors 9a and 9b shown in FIGS. 3 (a) and 8 (a). When moved in the opening direction, that is, in the right direction, the interlocking roller 18 that slides on the sliding contact portion 141 of the door wheel plate 14 of the outer sliding door 9b and the sliding contact portion 71 of the upper frame 7 is moved around the vertical axis 17 along with the movement. It moves in the same direction as the moving direction of the outer sliding door 9b while rotating horizontally. At this time, the moving distance of the interlocking roller 18 moves by L / 2 with respect to the moving distance L of the door wheel plate 14 of the outer sliding door 9b. Therefore, the inner sliding door 9a moves in conjunction with the movement distance of the outer sliding door 9b by a half of the movement distance, and finally the sliding doors 9a and 9b are moved as shown in FIGS. 3 (b) and 8 (b). It overlaps and it will be in the fully open state accommodated ahead of the sleeve wall 10. FIG.

  In this interlocking type sliding door 9, as shown in FIG. 3 (a), the sliding door 141 of the outer sliding door 9b is linked to one end in the longitudinal direction of the sliding contact portion 141 when the outer sliding door 9b is fully closed. A feature is that a part of the peripheral surface of the roller 18 is provided with a recessed portion 23 to be engaged.

  For example, as shown in FIG. 4 to FIG. 7, the recess 23 is processed into a shape in which a part of the circumference of the interlocking roller 18 falls and engages, as shown in FIGS. 4 to 7. When the door plate 14 is pressed into a predetermined cross-sectional shape, it can be processed simply and at low cost by simply pressing one end in the longitudinal direction. In addition, if one end of the recessed portion 23 is provided with a convex portion 24 having a cross-sectional mountain shape that overcomes just before the interlocking roller 18 falls, the falling engagement state is ensured without the interlocking roller 18 returning carelessly after dropping. Can be retained.

  The interlocking roller 18 is provided with a spring 25 (see FIG. 3A) on the swing shaft 22, and the spring 25 always presses the interlock roller 18 against the sliding contact portion 141 of the door plate 14 around the swing shaft 22. By energizing, the interlocking roller 18 is surely dropped into the recess 23 when the outer sliding door 9b is fully closed.

  In this case, when the outer sliding door 9b is fully closed as shown in FIGS. 3A and 8A, a part of the peripheral surface of the interlocking roller 18 is provided on one end side in the longitudinal direction of the door plate 14 of the outer sliding door 9b. Since it falls into and engages with the recess 23, the outer sliding door 9b can be prevented from bouncing against the left column 2 (see FIG. 1) of the opening 6.

As another embodiment, instead of providing the recess 23 in the door plate 14, the upper frame 7 corresponding to one end side in the longitudinal direction of the door plate 14 as shown by a two-dot chain line in FIG. It can also be provided in the middle part in the longitudinal direction of the inner wall part 7a. In this case, the interlocking roller 18 is always pressed and urged by the spring 25 against the sliding contact portion 71 of the upper frame 7 around the swing shaft 22.
As described above, since the recessed portion 23 is provided on the door wheel plate 14 or the upper frame 7 with which the interlocking roller 18 is slidably contacted, it is fully closed as in the case where the rail itself on which the door wheel rolls is provided with a concave portion or a convex portion as in the conventional case. There is no problem that the sliding door sometimes tilts to create a gap, or the sliding door tilts immediately before full closing and lacks smoothness of full closing operation, and the interlocking sliding door 9 does not tilt and can be fully closed smoothly. Can do.

  In order to prevent the outer sliding door 9b from bouncing against the right end column 2 of the opening 6 not only when the outer sliding door 9b is fully closed but also when the outer sliding door 9b is fully opened, as shown in FIG. When the outer sliding door 9b is fully opened, the interlocking roller is also applied to the other end in the longitudinal direction of the door plate 14 or the end in the longitudinal direction of the inner wall 7a of the upper frame 7 corresponding to the other end in the longitudinal direction of the door plate 14. A concave portion 26 is provided in which a part of the peripheral surface 18 is depressed and engaged. Thereby, the rebound of the interlocking type sliding door 9 can be prevented both when the interlocking type sliding door 9 is fully closed and when it is fully open. It should be noted that, similarly to the case of the notch 23, it is preferable to provide a convex portion 27 having a mountain-shaped cross section that gets over just before the interlocking roller 18 falls, similarly to the case of the notch 23.

It is a perspective view of the assembly place in which the rebound prevention apparatus of the interlocking type sliding door which shows one Example of this invention was integrated. It is a principal part vertical side view of FIG. (A) is a principal part cross-sectional plan view which shows the fully closed state of the interlocking type sliding door of FIG. 1, (b) is a principal part cross sectional plan view which shows the fully open state of the interlocking type sliding door of FIG. It is a perspective view of the recessed part of the door roller plate shown in FIG. It is the sectional view on the AA line in FIG. It is the BB sectional view taken on the line in FIG.
