Description

Detailed Description of the Invention The present invention provides a door that can be opened and closed by sliding, but can also be opened and closed by swinging if necessary, by retracting the steady rest by operating an opening operation part such as a touch plate, and opening and closing by swinging. This invention relates to a door opening/closing device that makes it possible to open and close doors.

The applicant has already proposed a door that can be opened and closed by sliding or swinging as shown in Figures 1 to 3. This is done by suspending a hanging frame (4) from the upper rail (2) inside the blind (1) via a pulley (3), and then attaching a door (5) to the hanging frame (4). It is a hanging thing. Then, by the forward and reverse rotation of the drive device (6),
The left and right doors (5) (5) are connected via the belt (7) (7) and pulleys (8) (8) to the inset door (9) as shown in Figure 2.
j Open and close by sliding along (9).

Here, when a larger opening than the door (5) is required, such as when bringing in large items or when an abnormal situation such as a fire occurs, as shown in Figure 3,
When the door (5) is pushed outward, the retaining part α4) α4) of the door (5) with the hanging frame (4) comes off and the swing fulcrum part (10) QO
), and as the door (5) swings, the fitted door (9) is also pushed out and the vertical pivot point α1
)α1) (12) (Swing around 12+.

Even if the door (5) (5) remains open, the pillars on both sides Q3)03
) to obtain twice the normal width.

However, for such doors that can be opened and closed by either sliding or swinging, the primary purpose is usually to ensure that locking is easy and secure, and that the door is sufficiently closed in the event of an emergency such as a fire. Sometimes it is required to satisfy the contradictory conditions of being able to open and close easily by swinging. Furthermore, the second objective is that the locking means and the opening/closing control means are preferably compact, unitized, and can be easily attached to a door frame, etc., and operate reliably.

The present invention has been made to achieve the above-mentioned first object, and is provided with a ratchet that is biased in one direction by a single spring on a door that can be opened and closed by sliding and swinging, and a ratchet that is biased in one direction by a single spring. A steady rest is provided at the lower end of the wire, which is normally driven by a spring to extend beyond the lower stile of the door to engage and disengage from the lower rail, and the tip of the other wire connected to the ratchet is provided with a steady rest that is driven when the door swings to open and close. A drive cam is connected to the drive cam, and an opening operation section is provided in the middle of the door facing the ratchet, and the opening operation section is engaged with the ratchet to loosen the wire and maintain the steady rest in the advanced position. It is provided so that it can be freely engaged and detached from the ratchet.

Still, the present invention has been made in order to solve the second object, and includes a steady rest, a locking means, a drive cam that is driven by the closing operation of the door by swinging, and a swing that is connected to the drive cam. It consists of a ratchet for holding the stop, a lock that locks and unlocks the locking means and has an unlocking body, an opening operation part that releases the ratchet from holding the steady rest, and a wire that connects each part. . With this configuration, the steady rest is protruded in conjunction with the closing operation by swinging the door, and the locking means is unlocked by the single opening operation, and the steady rest is retracted to immediately open the door. It can be opened by swinging. In addition, since each part is connected by wire, the structure is simple and the operation is reliable.

so that it can be stored and installed within 1.

Next, the operation of the opening/closing device according to the present invention will be explained. Fourth
Figures (a), (b), and (C) show the door (5) being opened by swinging. In this state, the latch fitting 09) and the engagement plate (20) are not engaged. In addition, the touch part t50) as the opening operation part is also pressed, and the ratchet pawl (54) is disengaged from the notch G5) of the ratchet (to). 40) and rotates to the right as shown in Fig. 4(b).Therefore, the wire (36) is attracted downward, and the wires (4I) and (42) are attracted upward.The wire ( The cam head) is sucked downward.
The drive cam (25) rotates to the left around the shaft (35'l) and is engaged with this cam @, as shown in Figure 4 (a).
), it rotates to the right in the figure. Wire (41)
The steady rest at the bottom (
4,1 is also rising against the spring (47). At this time, since the wire (42) is also being sucked upward, the unlocking body (59) of the lock (56) is also rising, and therefore, in conjunction with this unlocking body (59), The lower lock bin (60) also rises. If this lower lock pin ■ rises, the wire (63) may become slack (6
At G), the rond (67) is lowered, and the upper lock bin (70) provided above the rond (67) is lowered by a spring (69).

Here, in order to return to the sliding opening/closing state, the door (5) is swung from the hanging frame (4) using the pivot point (JO) as a fulcrum.
When pulled to the side, it returns to the state shown in Figure 5. Then, the retention part 04)
The engagement plate (20) and latch fitting (19) are shown in Fig. 4(b).
At the same time, the latch fittings (
The contact member (24) integrated with the drive cam plate (25)
The drive cam +251 is rotated to the left in the figure by contacting the claw piece (29) of the drive cam +251. The claw piece (29) of this drive cam 05)
Until the cam (33) is removed from the contact member (24), the tip C34) of the cam (33) rotates to the right as shown in FIG. 5(a). Then, the wire 06) is pulled upward, and the ratchet (to) rotates to the left in the figure against the spring (40). By rotating this ratchet (to) to the left, the wire (
4υ will be slack, so the steady rest (431 will spring off (47)
) to descend. At this time, even if the lowering of the steady rest (49) and the groove of the lower rail (48) do not match due to timing, and the door roller (49) contacts the floor, the steady rest (431) is held downward by the spring (47). The bottom rail (
48) at a position that matches the groove. Also, as the ratchet (blade) rotates to the left in the figure, its notch 69 slightly exceeds the position of the ratchet pawl (54) and the gap (
a) occurs. And the drive cam (claw piece (29) of 251)
When the ratchet μs) comes off the contact member 04), the ratchet μs) attempts to return to its original position with a spring (40) and rotates to the right, but
When it returns by the distance of the gap (d), it is locked by the ratchet pawl (54) and will not return any further. However, the drive cam (
25) and the cam (33) are connected to the gap (d) between the ratchet (to)
) minutes return to the original position as shown in Figures 6(a) and (b). Note that the wire (42) connected to the unlocking body (59)
) also loosened, but no other force acted to lower the unlocking body (59), so the lower lock pin (60) rose. )
It also fell down, both mouths Tsukubin (60) (70
) is not locked.

Next, when closing and locking the door (5), use the key 6B or the knob I5 to lock it.
), the lower lock pin (60) is lowered.

At this time, the wire (42) is loose, so the unlocking body (59)
) also falls.

When the lower lock pin (60) descends, the lower rail (4
8), and at the same time, the wire (63) is pulled down against the spring (66), and the link (to)
rotates to the left in the figure and rises against the spring (66), and then the upper lock bin (
γ0) against the spring (69) and lock plate (7).
]) and is locked, and the power switch (72) is turned off. At this time, the wire (42) connected to the unlocking body (59) is not loosened, but it is not related to the operation of the steady rest (43).

Next, in an emergency, when the touch part (!io) as the opening operation part is pushed against the spring (53) as shown in FIG. When it rotates to the fulcrum, the notch (!i5) of the ratchet (38) and the ratchet pawl 64) are removed, and the ratchet (38) is rotated to the right in the figure by the spring (40).

Since the wire (36) is pulled down by the rotation of the ratchet (support), there is no slack in this wire (support). At the same time, the wire (4υ (42)) is pulled up, so the steady rest (431) connected to one wire (4I) is thrown off (47
) and escape from the lower rail (48).

As the unlocking body (59+) connected to the other wire (421 rises, the lower lock (60) which is interlocked with this unlocking body 69 via the slider inside the lock also rises and opens into the lock hole (6).
2) and the wire (63) connected to the lower lock pin (60) becomes slack, so the spring (6G)
Due to this, the link (67) is lowered and the link (67) is lowered.
5) rotates to the right in the figure, and therefore the spring (69)
The upper lock pin (70) also descends and the lock plate (
7I), and the power switch (72) is turned on. If the door (5) is strongly pushed outside in this state, the door (5) will come off the retaining part Q4) and swing around the swing fulcrum part 00), resulting in the state shown in FIG. 4.

In the above embodiment, the touch part r50) is used as the opening operation part.
Although we have explained the case where the touch panel is formed with a rectangular touch plate and attached to the text type 05), the present invention is not limited to this. It's okay. Alternatively, it may be shaped like a small push button, usually covered with a thin transparent plate, and then broken and pushed in case of an emergency. In addition, although the opening operation part was made to work by pushing with the hand, it still works by kicking, stepping, or hitting the body with the foot, even if it is pulled, turned, pulled up, or pulled down. You can also do this.

Since the present invention is configured as described above, when the door that has been opened by swinging is closed again to the sliding open/closed state, the steady rest is automatically set in conjunction with the closing operation. Further, even if the locking means is locked and the steady rest is set, when the opening operation part is operated, the steady rest holding ratchet is released and the steady rest is retracted, and
The locking means is also unlocked, and the door can immediately be opened by swinging. Furthermore, since each part is connected by wire, the structure is simple and operation is reliable, and all the mechanisms can be housed as a unit within the door pattern.
