The specific embodiment
To by Application Example basic design of the present invention and operation be described by the reference accompanying drawing below.
[embodiment 1]
Fig. 1 represents the basic design of blocking device of the present invention.This blocking device can be divided into three groups of parts: the parts that are installed on door hanger 10; Be installed on the parts of car support frame (not shown); And the static parts that are installed in the hoistway (not shown).The parts that are installed on door hanger 10 are the static latch 16 and first cam 9.The stop place is static is installed in the hoistway at each for guiding surface 1.Guiding surface 1 adjacent doors inlet location.In addition, be positioned at the door pocket rear of door frame by making guiding surface 1, even under the situation of glass door or glass hoistway, also can not cause adverse effect to outward appearance.
The concrete structure of blocking device is described based on Fig. 2 to Fig. 6 here.Fig. 2 and Fig. 3 represent that car is positioned at stop place and door closing state.
Though not shown, door hanger 10 is installed on the door track on the last outer wall that is arranged in car entrance, thus the opening and closing direction free motion of edge door.In addition, support 19 is installed on door hanger 10, and Cam rest 18 is installed on door hanger 10 and is positioned at the below of support 19.
Hinged block (hinge block) 12 is articulated and connected at first hinge-point, 15 places.Slider rod 3 and door bolt 2 are installed on hinged block 12.Slider 4 is in slider 4 and hinged block 12 contacted default position.In this default position, door bolt 2 and slider rod 3 are horizontal, and at guiding surface 1 and be installed between second roller 5 of slider 4 and have gap (standard setting gap).Like this, when slider 4 is in default position, the contact noise of second roller 5 and guiding surface 1 during advancing, car can not take place.When slider 4 was in default position, first cam 9 was mounted to and makes the roller 7 of winning just in time contact the rake 9a of first cam 9.Switch contact 14 is installed on door bolt 2, and it contacts with switch 13 when the level attitude shown in this door bolt is in.Shown switch contact 14 and switch 13 only are examples.Can adopt the safety switch of other type in a similar manner.
With the bolt that passes groove 27a guide surface bracket 27 is fastened on the stop door frame (not shown).With the bolt that passes groove 27b guiding surface 1 is fastened on the guide surface bracket 27.The shape of guide surface bracket 27 depends on the shape of stop door frame certainly, and is not limited to Fig. 4 to design shown in Figure 6.In addition, can regulate the position of guiding surface 1 along following both direction, this both direction be formed on guide surface bracket 27 in elongated slot 27a, 27b vertically corresponding, promptly, be used to regulate gap between first roller 7 and the guiding surface 1, be parallel to a travel direction, and the stationary parts that is used for being adjusted in hoistway during advancing at car and the gap between the parts that move of car, perpendicular to the door travel direction.In addition, when needed can be by between guide surface bracket 27 and stop door frame, the upright position that pad is regulated guiding surface 1 being set.
Blocking device of the present invention operation in (in the stop zone) in the release zone is at first described.
Fig. 7 to Fig. 9 represents to open up to the surperficial blocking device 1 time of second roller, 5 contact guidances at the release intra-zone when door with dividing.In this case, door is opened a segment distance, and this distance and second roller 5 when door is closed equate with standard setting gap between the guiding surface 1.First cam 9 is with door edge moving to right as shown in Fig. 7 and Fig. 8, and backup first roller 7.Therefore first bar 11 that is articulated and connected must rotate counterclockwise, as shown in Fig. 7 and Fig. 8.This rotation of first bar 11 makes 8 motions of second hinge-point.Second bar, the 6 shared second identical hinge-points 8.Since the regular length of second bar 6, another hinge-point of second bar 6, and promptly the 3rd hinge-point 17 also must motion.By second bar 6 F that on the slider 4 of shared identical the 3rd hinge-point 17, exerts pressure

RVAnd the product of the distance between the 3rd hinge-point 17 and first hinge-point 15.The gravity F of whole linkage 25
COMProduce the clockwise torque around first hinge-point 15, this torque equals F
COMAnd the product of the horizontal throw between the barycenter of linkage 25 (COM) and first hinge-point 15.The quality of linkage 25 and barycenter (COM) are arranged such that clockwise torque is greater than the conter clockwise torque.Thereby, replace the rotation of door bolt 2, have the slider 4 of second roller 5 and will be along slider rod 3 towards guiding surface 1 move, contact with guiding surface 1 up to second roller 5.That is, door bolt 2 and slider rod 3 remain on their latched position, contact with guiding surface 1 up to second roller 5.
Here, as shown in Figure 8, slider 4 is away from hinged block 12 motions.In addition, leaving gap not between second roller 5 and guiding surface 1.
Figure 10 and Figure 11 represent to open and fasten with a bolt or latch with dividing blocking device when being in the unlocked position when car door at the release intra-zone.
At this moment, as shown in figure 11, switch contact 14 is contact switch 13 no longer.
The operation of (overseas) outside the release zone of various details blocking device at landing zone.
Figure 12 to Figure 15 represents when the state of door when the release region exterior is opened with dividing.At this state, for example the passenger manually opens door between two-layer.
As shown in Figure 10 and Figure 11, for the car door that is positioned at the release zone, second roller 5 is opened contact guiding surface 1 between moving period at continuous door, makes the 3rd hinge-point 17 upward movements.
Yet to shown in Figure 15, in the time of when car door is positioned at the release zone outside, guiding surface 1 does not exist as Figure 12, thereby open at continuous can upward movement between moving period for the 3rd hinge-point 17.In this case, slider 4 will be owing to power F
RHorizontal component, i.e. power F
RHAnd, be hooked in door bolt 2 rears up to static latch 16 along slider rod 3 continuouss movement.That is, door bolt 2 and slider rod 3 remain on their latched position.Because static latch 16 is installed on door hanger 10, so in case static latch 16 is hooked in door bolt 2 rears like this, door hanger 10 just can not further continue to open.
[embodiment 2]
With reference to Figure 16 to Figure 19, support 22 has horizontal flanges 22a and vertical flanges 22b, and is installed on the top of slider 4.Support 21 has at the first flange 21a of two differing heights place horizontal curvatures and the second flange 21b, and is installed on bar assembly stay bearing plate 26.The first flange 21a near bar assembly stay bearing plate 26 is positioned at the level height identical with horizontal flanges 22a.In addition, as shown in figure 16, near the default position of hinged block 12 location, between the first flange 21a and horizontal flanges 22a, only there is negligible horizontal clearance at slider 4.In addition, vertical flanges 22b is positioned between the first flange 21a and the second flange 21b.
When opening under the situation that is positioned default position at slider 4, first roller 7 is pushed upwardly along the rake 9a of first cam 9.This motion of first roller 7 produces and is used to make door bolt 2 to center on the power that first hinge-point 15 rotates counterclockwise, as shown in figure 16.When door bolt 2 when under this power effect, beginning to rotate, the horizontal flanges 22a of support 22 almost with the direct butt of the first flange 21a.On support 22, slider 4 is being moved, as shown in figure 16 by the reaction force acts that produces with the horizontal flanges 22a of the first flange 21a butt on right along slider rod 3.Under slider 4 was bonded at situation on the slider rod 3 for some reason, above-mentioned reaction force acts made slider 4 to move and fastens 2 with a bolt or latch and can not rotate so that slider 4 discharges from slider rod 3.Here, the first flange 21a and horizontal flanges 22a have constituted the slider motion-generating device.
Then, slider 4 moves to Figure 18 and default latch position shown in Figure 19 along slider rod 3.In this default latch position, vertical flanges 22b be positioned at the second flange 21b under, and between flange 21b and 22b, have little down suction.Here, this default latch position and static latch 16 from its complete off position up to corresponding with the decline of slider 4 motion paths of door bolt 2 butts.The second flange 21b and vertical flanges 22b have constituted the pivoting detent device.
It should be noted that in others the structure of embodiment 2 is identical with the foregoing description 1.
In the normal door opening operation in the release zone, before vertical flanges 22b arrives the second flange 21b, second roller 5 and guiding surface 1 butt.Thereby fastening 2 with a bolt or latch can rotate and release.
In addition, when door was opened outside the release zone, vertical flanges 22b moved below the second flange 21b.From that time, owing to having limited, the butt between the vertical flanges 22b and the second flange 21b fastens 2 rotation with a bolt or latch.Then, static latch 16 motions are hooked in door bolt 2 rears up to it, thereby prevent further door opening operation.When the gap of setting between flange 21b and the 22b, considered the installation and the car inclination situation of worst case.
[embodiment 3]
