Description

evacuation device

The present disclosure relates to an evacuation device.

As an evacuation device in which a handrail capable of shifting operation from a lying posture to a standing posture is provided on an elevator platform, the one described in Japanese Patent Application Laid-Open No. 2010-51473 is known. In this prior art example, in order to use an evacuation device, first, after opening the cover body, it is necessary to shift the handrail to a standing posture, and there exists a problem that labor is required.

The present disclosure has been made in order to solve the above drawbacks, and an object of the present disclosure is to provide an evacuation device with good usability.

According to the present disclosure, the object is

an elevator that descends from the standby position held on the upper floor to the lower floor;

A cover body that conceals the upper surface of the elevator in the standby position;

a handrail that is freely connected to a handrail bracket fixed on the hoisting platform in the standing posture side from the proximal posture to the standing posture, and is freely connected to the handrail, and is held in the lowered posture by the cover body;

This is achieved by providing an evacuation device having a handrail lock that regulates the movement of the handrail to the falling posture in accordance with the transition from the open state of the cover body to the standing posture of the handrail.

The handrail is biased in the standing posture direction, and is held by the cover body in the falling posture. When the cover body is opened from this state, the handrail shifts to the standing posture by the biasing force, and the handrail lock body regulates the movement to the falling posture in accordance with the transition to the standing posture of the handrail, and the standing posture is maintained.

Accordingly, in the present disclosure, since the handrail is shifted to the standing posture in the use state only by performing the opening operation of the cover, there is no need to separately perform the standing operation of the handrail, thereby improving usability.

In addition, as another form of the present disclosure,

The handrail lock is formed to be movable by being biased toward the locking position between a locking position for regulating movement of the handrail in the standing posture to the return posture and a locking and evacuation position for allowing movement of the handrail to the return posture,

The handrail bracket is provided with a locking operation member that is free to move between the initial position and the operating position, and drives the handrail lock from the locked position to the locked and evacuated position according to the movement operation from the initial position to the operating position;

The locking operation member may constitute an evacuation device for restraining the handrail lock to the locking evacuation position in the operating position by resisting the biasing force.

In the present disclosure, the handrail lock is movable between a locking position that interferes with the movement trajectory of the handrail during movement between the standing posture and the lying posture, and a locking evacuation position where the interference is eliminated, and from the locked position to the standing posture. The movement of the railing to the loin position is regulated, and movement of the balustrade to the loin position is permitted by the movement to the locked evacuation position.

The locking operation member is movable between the initial position and the operating position, and by moving the handrail locking body to the locking evacuation position according to the movement operation from the initial position to the operating position, movement from the standing posture of the handrail to the falling posture is possible becomes

The lock operation member can be held in the operating position by an appropriate means, and in this state, the handrail lock body is held in the locking evacuation position, so that the lowering operation on the handrail is permitted.

Therefore, in this aspect, if the cover is closed while the locking operation member is moved to the operating position, the handrail can be inverted according to the occlusion of the cover. Therefore, after the handrail is inverted, the cover is further removed. The need for occlusion operation is eliminated, improving usability.

The locking operation member can be operated to release the restraint to the operating position after the handrail has shifted to the lodging position to return it to the initial position,

The lock operation member constitutes an evacuation device that is driven to the initial position in accordance with the movement of the railing to the falling posture, so that it is possible to move to the initial position without performing a restraint release operation, so that usability is improved.

It is also possible for the locking operation member to be configured to translate between the initial position and the actuated position,

The lock operation member is free to rotate between the initial position and the operation position, and according to the rotation toward the operation position side, the handrail lock body is pushed into the lock and evacuation position;

When the handrail lock in the locking and evacuation position presses the locking operation member to the end of the rotation stroke on the operating position side, and the locking operation member constitutes an evacuation device that holds the handrail lock in the lockout position, You can do it simply.

Further, as another form of the present disclosure,

The handrail lock includes a locking position that regulates the movement of the handrail in the standing posture to the prostration posture, and a temporary holding position that permits the movement of the handrail to the prostration posture and is discharged in accordance with the movement of the handrail to the prostration posture. It can be moved by being biased toward the locking position between

The handrail bracket can be configured with an evacuation device provided with a stopper wall that resists a biasing force toward the locking position and holds the handrail lock in the temporary holding position.

In this aspect, when the handrail lock is held in the temporary holding position when the handrail is in the standing posture, and the handrail is brought down from this state, the handrail lock is pushed out from the temporary holding position by the handrail, and the It returns to the locked position by the biasing force to the side. Since the handrail locking body in the locked position does not restrict the movement to the return posture side when the handrail is detached from the standing posture, the subsequent takeover operation on the handrail is permitted.

Therefore, in this form, if the handrail lock is once held in the temporary holding position and the cover is closed, the handrail can be rolled over according to the blockage of the cover. Therefore, after the handrail is overturned, further The necessity of closing the cover body is eliminated, and the usability is improved.

Further, the temporary holding position can be configured such that the handrail lock is spaced from the locking position and disposed at a position that enters into the transit path of the handrail through a non-interference path with the handrail in the standing posture.

in this case,

If the temporary holding position constitutes an evacuation device formed by cutting out a recess in which the locking body can fit into the non-interfering path, the wall surface opposite to the locking position of the recess becomes the stopper wall, so that the structure can be simplified.

Also,

When an evacuation device is configured in which the handrail lock is connected with a first tension member having one end connected to the center of rotation of the handrail and a second tension member for biasing the handrail lock body in the temporary holding position to the locked position side. The sieve can be held in a locked position and a temporary holding position with a simple configuration.

Furthermore

The handrail is formed in a U shape and is connected to the handrail bracket at the free end, respectively, and the handrail lock is formed in the shape of a rod erected between the handrail brackets to form an evacuation device that can be operated simultaneously. , since the bar-shaped handrail locking body erected between the brackets can be pushed in and moved to the temporary holding position, the operability is improved.

According to the present disclosure, it is possible to improve the usability of the evacuation apparatus.

As shown in Fig. 1 or less, the evacuation apparatus includes a case 2a that is fitted and fixed to an opening formed in the floor 1 on the upper side to form an evacuation opening 2, and an evacuation opening 2, It has a cover body (5) for closing, a guide post (14) which is erected on the bottom surface (3) of the lower floor, and whose upper end is fixed to the opening (2) for evacuation, and a platform (4).

As shown in FIG. 1 , the elevator platform 4 descends from a standby position held in the evacuation opening 2 and the guide post 14 from this standby position and lands on the lower floor surface 3 . It is driven up and down between the evacuation positions that do.

The guide post 14 is a hollow pipe body having an appropriate buckling strength, and is formed by extrusion molding, for example, aluminum. The lower end of this guide post 14 is fixed to the lower floor slab, and the upper end is fixed to the case 2a.

In addition, a rack groove 14a is formed on one side wall surface of the guide post 14 . As shown in FIG. 1 , the rack groove 14a is formed by forming concave portions 14b at a predetermined pitch in a high-strength plate material such as stainless steel, and is formed over approximately the entire length of the guide post 14 .

Further, in this case, as shown in FIGS. 3A and 3B , if the concave portion 2b is formed at the lower end of the periphery of the case 2a, the elevator 4 rises from the retracted position to reach the standby position. It is possible to prevent the occurrence of a collision sound between the lower cover and the lower edge of the case (2a).

Further, as shown in Figures 4 and 5, the hollow portion of the guide post 14, the weight 15 suspended by a wire (not shown) is accommodated, and after the elevator 4 reaches the lower floor, the user When the platform 4 is lowered, the platform 4 returns to the standby position by the weight of the weight 15 .

As shown in Fig. 6, the platform 4 is formed to have a sufficient width and load-bearing capacity for a user of the wheelchair 16 to ride, and the wheelchair 16 is, in Figs. You can get on and off the wheelchair mounting area 4a in the central part from the rear. An auxiliary space 4b for a guardian to ride is formed in the inclined rear of the wheelchair mounting area 4a.

In addition, in this specification, let the advancing direction (the right side in FIG. 4) of the wheelchair 16 be "front", the riding side shall be "rear", and let the up-down direction be "side" in the drawing.

As shown in Figs. 4 and 5, on each side of the lifting platform 4, a post insertion opening 4c through which the guide post 14 is inserted is formed, and the post insertion passage opening 4c is interposed therebetween. Before and after being placed in the pedestal, a buckling device 17 for lowering the descending speed of the hoisting table 4 is mounted. A pinion 17b engaged with the concave portion 14b of the guide post 14 is fixed to the rotation shaft 17a of the bracing device 17, and the number of rotations of the pinion 17b is set to the bracing device 17. The lowering speed of the elevator platform 4 is reduced by decelerating it.

In addition, the lifting platform 4 is provided with rollers 18 which are in contact with the front-rear wall surface of the guide post 14 and the outer side wall surface, so that shaking and the like at the time of lifting and lowering are regulated.

Furthermore, the handrail 7 is arrange|positioned at the front edge part of the hoisting table 4 . The handrail 7 is formed by bending a pipe body, and has a crosspiece 7a and a crosspiece 7b extending in a right angle direction from both ends of the crosspiece 7a, and is formed in a U-shape. The handrail 7 is attached to the elevator platform 4 by rotatably connecting the free end of each vertical rod 7b to the handrail bracket 6 fixed to the elevator platform 4 .

The handrail 7, as shown in FIG. 1, is positioned between the protruding posture along the surface of the platform 4 and the standing posture in which the cross bar 7a is pulled upward, as shown in FIG. can move rotationally. The handrail 7 is biased toward the standing posture, and by closing the cover body 5 , the fall posture is maintained, and automatically shifts to the standing posture according to the opening operation of the cover body 5 .

The detail of the handrail 7 is shown to FIG. 7, 8. As shown in Fig. 8, each longitudinal pole 7b of the handrail 7 is connected to the handrail bracket 6 at a position slightly upward from the lower end so as to function the free end of the lower end as a locking operation piece 7c, The torsion spring 7d applies a biasing force to the standing posture side, that is, in the clockwise direction in Fig. 8 .

As shown in Fig. 8, the handrail bracket 6 is provided with a long hole-shaped moving passage 19 connecting between the locking position, unlocking position, and temporary holding position to be described later, and the handrail brackets on both sides ( 6) Both ends of the bar-shaped handrail locking body 8 spanned therebetween are inserted into the moving passage 19 .

The locking position is provided at a position where the handrail locking body 8 obstructs the movement path of the locking operation piece 7c to the falling posture side when the handrail 7 is in the standing posture, as shown in Fig. 9C, , the unlocking position at which the handrail locking body 8 is located in Fig. 9b is provided at a position where the handrail locking body 8 does not interfere with the movement trajectory of the locking operation piece 7c.

Further, in Fig. 9D, the temporary holding position at which the handrail locking body 8 is located is extended from the unlocking position toward the rear, and a non-interfering path 10 that does not interfere with the movement trajectory of the locking operation piece 7c. is installed at a position where the end of the locking operation piece 7c re-enters the interference region with the movement trajectory, and in this example, a notch-shaped recess 11 into which the handrail locking body 8 can be fitted is installed on the handrail ( 7) is formed by extending in the direction of the rotation center.

Further, in order to determine the position of the handrail locking body 8 in the movement passage 19 , the handrail locking body 8 has a first tension member having one end fixed to the rotational center C7 of the handrail 7 . A first tensioning spring 12 as a rod and a second tensioning spring 13 as a second tensioning member whose one end is fixed to the front end of the handrail bracket 6 are connected.

Accordingly, in this example, when the cover body 5 is opened, the handrail 7 moves from the falling posture shown in Fig. 8 to the standing posture side by the restoring force of the torsion spring 7d. With the transition to the standing posture, first, as shown in Fig. 9A, the locking operation piece 7c interferes with the handrail locking body 8 held in the locked position, and as it moves further toward the standing posture, As shown in Fig. 9B, the handrail locking body 8 is pushed toward the unlocking position.

Thereafter, when the handrail 7 is further moved to the standing posture side, the handrail locking body 8 returns to the locked position as shown in Fig. 9C by the restoring force of the first and second tension springs 12 and 13. .

When the handrail 7 is in the standing posture, the handrail locking body 8 in the locked position moves the movement of the locking operation piece 7c in the fall position direction, as shown in Fig. 9C, through the moving passage 19. Since it is regulated by the wall surface of , the handrail 7 does not fall down even if a force in the falling direction is applied to the handrail 7 .

From this state, as shown in FIG. 9D , when the handrail locking body 8 is moved beyond the unlocking position to the temporary holding position, the handrail locking body 8 is temporarily held by the first tension spring 12 . While being pressed against the end wall of the holding position, movement in the locking position direction by the biasing force of the second tension spring 13 is blocked by the stopper wall 9 formed by the wall surface of the concave portion 11 . As a result, there is no deviation from the temporary holding position.

Further, as shown in Figs. 4 and 5, since the central portion of the handrail locking body 8 is open to the rear of the elevator platform 4, only pushing the central portion of the handrail locking body 8 toward the rear Also, the handrail locking body 8 moves to the end of the non-interfering path 10, and then, when the pushing operation is finished, it can be moved to the temporary holding position by the restoring force of the first tension spring 12. have.

Further, when the handrail 7 is rolled over from the state of Fig. 9d, that is, the handrail 7 is in the standing position and the handrail lock 8 is in the temporary holding position, the handrail locking body 8 is It is pushed out from the temporary holding position to the non-interference path 10 by the locking operation piece 7c, and then returned to the locked position by the restoring force of the second tension spring 13.

Therefore, in this example, after use of the evacuation device, only moving the handrail locking body 8 to the temporary holding position in the state in which the elevator platform 4 returns to the standby position, and then closing the cover body 5 is It is also possible to move the handrail 7 to the proximal position.

In this example, one end of the torsion spring 7d penetrates the mounting piece 6a of the handrail bracket 6 to the elevator 4 and is inserted into the elevator 4 as shown in Fig. 8, but Figs. 10a to As shown in FIG. 10C , it is also possible to engage the rear bent piece 6b of the handrail bracket 6 .

In addition, in each subsequent Example, the component substantially the same as that of the above-mentioned embodiment is given the same code|symbol in the drawing, and description is abbreviate|omitted.

A lock operation unit 21 for operating a lock member 20 to be described later is disposed on the handrail 7 described above. The lock operation unit 21 is installed in the center of the crosspiece 7a of the handrail 7, and can be operated by any arm that is not inconvenient of the person to be seated in the wheelchair 16, or by the guardian in any auxiliary space 4b. A pair is provided at a symmetrical position with respect to the central position of the crossbar 7a so that it can be operated over the shoulder of the person to be protected even if it is overturned.

The pair of locking operation portions 21 are provided with gear-shaped portions 21a meshing with each other so that the inner wire 22b, which will be described later, can be operated synchronously even when any of these lock operation portions 21 are operated.

In addition, each lock operation unit 21 can be operated by the person to be protected simply by putting his or her arm on the lock operation unit 21 and applying a weight, or by pushing the person over the shoulder of the person to be protected. As shown in Figs. 6 and 11 , it is shaped like a lever, and it is considered that the lock release operation of the lock member 20 can be performed by pushing it down.

The operation of the locking member 20 by these locking operation parts 21 is performed using the wire device 22 in which the inner wire 22b is freely inserted into the outer cable 22a, and Figs. 11, 12A, and 12B. As shown in , each of the inner wires 22b is connected to each of the locking operation parts 21 that can be rotated around the rotational center C21.

In order to use the wire device 22 as the full specification, the inner wire 22b is inserted into the lock operation part 21 opposite to the lock operation part 21 to be connected. After the wire device 22 connected to the lock operation unit 21 is drawn into the inner space of the handrail 7 from the wire introduction opening 7e formed in the pipe-shaped handrail 7, as shown in FIG. , as shown in Fig. 5, is again drawn out of the handrail 7 from the wire lead-out opening 7f, and arranged to follow the stringer 7b of the handrail 7 to an appropriate height on the surface of the lift 4 It is connected to the conversion unit 23 to be described later.

Further, at the rear end of the wheelchair loading area 4a of the elevator 4, a flap 24 is freely rotatably connected in the vertical direction around the rotation shaft C24, and further, the elevator 4 is connected to the lower floor surface 3 ), an inclined surface 4d for absorbing the step with the lower floor surface 3 is formed in the state of landing.

As will be described later, the flap 24 is unlocked upon landing on the lower floor surface 3 to allow downward rotation, and after landing on the lower floor surface 3, the wheelchair 16 ), the flap 24 is rotated to be pushed down so that the free end is mounted on the inclined surface 4d, and can proceed to the lower floor surface 3 as it is.

In addition, in order to facilitate mounting of the wheelchair 16 in the standby position on the upper floor side, the slope 25 is connected to the evacuation opening 2 .

As shown in FIG. 6 , the slope body 25 is a plate body having a width dimension that allows the wheelchair 16 to pass through, and as shown in FIG. 13 , the free end is on the platform 4 . It rotates around the rotation center C25 between the setting position and the hanging posture of the state suspended from the opening 2 for evacuation, as shown in FIG. 14.

A setting roller 25a and a support roller 25b are connected to the free end of the slope body 25 . As shown in FIG. 13 , in the setting position, the support roller 25b rides on the inclined surface 4d and bears the load of the wheelchair 16 passing on the slope body 25 .

Further, as shown in Fig. 13, the flap 24 described above is mounted on the free end of the slope body 25 when the elevator platform 4 is in the standby position, and in this state, the upper floor side A slope 25 is spanned between the floor surface and the surface of the platform 4 to eliminate the step difference between the upper floor surface 1 and the surface of the platform 4 .

When the elevator 4 descends in this state, as shown in FIG. 14 , the slope body 25, which is not supported by the inclined surface 4d, rotates downward by its own weight and shifts to the hanging posture.

The setting roller 25a is in the direction of the setting position on the slope body 25 when the slope body 25 is in the hanging posture and comes into contact with the upper surface of the inner end of the auxiliary space 4b of the elevated platform 4, that is, It is arranged to generate a counterclockwise rotational operating force in FIG. 14 .

Therefore, in this example, when the platform 4 moves to the standby position side again after descending, first, the setting roller 25a comes into contact with the upper surface of the inner end of the auxiliary space 4b of the platform 4, and the slope body 25 As it rises with the platform 4, it returns to the setting position, and returns to the initial state shown in FIG.

Further, a damper 26 is attached between the evacuation opening 2 and the back surface of the slope body 25 in order to absorb an impact when the elevator platform 4 and the setting roller 25a collide with each other.

As described above, the flap 24 is freely rotatably connected to the rear end of the wheelchair mounting area 4a of the elevator 4, so that the standing posture shown in FIG. 14 and the free end are inclined surfaces 4d ), it rotates between the propulsion postures, and is biased toward the standing posture side by a torsion spring 27 wound around the rotating shaft C24. The angle of the flap 24 in the standing posture is determined to such an extent that it functions as a wheel stopper of the wheelchair 16 on the platform 4 in consideration of the longitudinal dimension of the flap 24 in the front-rear direction.

The flap 24 is controlled to maintain the standing posture by the flap locking unit 28, and is locked except when the elevator platform 4 is raised and lowered, that is, in a standby position and when landing on the lower floor surface 3, The standing posture is held, and when landing at the lifting end position of the lifting platform 4, that is, the standby position and the lower floor surface 3, the lock is released, and movement to the lowering posture is allowed.

As a result, during the descent of the platform 4, the standing posture of the flaps 24 is maintained to prevent the wheelchair 16 from falling from the platform 4, and the lifting terminal position of the platform 4, that is, waiting At the time of landing on the position and the lower floor surface 3, the movement to the prostration posture is permitted, and passage of the wheelchair 16 is not obstructed.

As shown in FIGS. 15A and 15B , the flap locking part 28 includes a locking control body 29 rotatably connected to the elevator 4, a free end of the flap 24, and a locking control body 29 . ) has a flap lock body 30 rotatably connected to each other, and each is formed with lock stoppers 29a and 30a that engage each other in a locked state.

The locking control body 29 is freely rotatable about a center of rotation C29 between the locked position and the unlocked position, and the flap locking portion 28 is provided so that the flap locking body 30 is locked in the locked position. The locking state is obtained by moving the locking stopper 30a to the locking stopper 29a of the control body 29 to the locking position.

Further, a torsion spring 31 is wound mounted on the rotation shaft C29M connecting the lock control body 29 and the flap lock body 30, and as a result, the rotation center C30 with respect to the flap 24 is rotated around the rotation shaft C29M. The flap lock body 30, which is freely connected to rotation, is biased toward the locking position by a biasing force by a torsion spring 27, and the lock control body 29 is mounted between the flap lock body 30 and the flap lock body 30. It is biased toward the locking position by the biasing force of the torsion spring 31 .

As shown in Fig. 15A, the connecting position of the flap locking body 30 and the locking control body 29, the connecting position of the locking control body 29 to the elevator 4, and the locking stoppers 9a in the locked state , 30a) is the intersection between the flap locking body 30 and the locking control body 29 when a movement operating force of the flap 24 in the falling direction is applied to the connection point with the flap locking body 30 It is set to become a relationship in which the change of the angle is regulated by the locking of the lock stoppers 29a and 30a.

That is, in FIG. 15B , when a rotational operating force in the falling direction is applied to the flap 24 , a force F acts on the connection point of the flap locking body 30 with the flap 24 , and the locking control body 29 . A counterclockwise rotational force is generated. The locking positions of the locking stoppers 29a and 30a are determined by the intersection angle θ of the acute angle side of the locking control body 29 and the flap locking body 30 by the counterclockwise rotation of the locking control body 29 . ), and as a result, the locking control body 29 and the flap locking body 30 behave as a substantially unitary thing with respect to the load of the flap 24 in the falling direction.

By integrating the locking control body 29 and the flap locking body 30, the flap 24, the locking control body 29 and the flap locking body 30 are integrated, and the lifting platform 4 is a link of three sections. Since the degree of freedom of movement is lost, the flap 24 can maintain a standing posture.

Further, the lock control body 29 extends downward from the connection point C29 to the platform 4, and when the platform 4 lands on the lower floor surface 3, the lock control body 29 is shown in Fig. 15A. A detection protrusion 29b that rotates in a clockwise direction (unlocking direction) is provided.

Therefore, in this example, when the platform 4 descends and lands on the lower floor surface 3, the index finger protrusion 29b is pressed against the lower floor surface 3 and rotates clockwise in Fig. 15A, that is, in the unlocking position direction. do. When the locking control body 29 rotates to the unlocking position, as shown in Fig. 16A, the lock stopper 30a of the flap locking body 30 is unlocked, and the locking control body 29 and the flap lock are released. The restraint of the connection point C29M of the sieve 30 is released, so that the flap lock body 30 can be rotated, and the flap 24 can move in the fall direction.

When the wheelchair 16 moves in this state, the flap 24 is pushed in by the wheel in the direction of the arrow in Fig. 16A, and the free end gets on the inclined surface 4d, and the wheelchair 16 is dismounted. it becomes possible

On the other hand, when the elevator platform 4 rises to reach the standby position vicinity, the slope body 25 shifts from the hanging posture to the setting position as described above.

13, at the free end of the slope body 25, an operation protrusion 25c for moving the flap lock body 30 in the disengagement direction with the lock control body 29 when moving to the setting position. is installed In this example, the operation protrusion 25c is formed in a protrusion shape that presses an arc-shaped pressurized valve 30b formed in the flap lock body 30 .

As shown in Fig. 16B, as the elevator platform 4 approaches the standby position, the operating protrusion 25c approaches the pressure target member 30b of the flap lock body 30, and eventually the pressure target member 30b. The silver is pushed forward by the operation projection 25c.

The locking stopper 30a of the flap locking body 30 and the locking stopper 29a of the locking control body 29 pushed forward by the operating protrusion 25c are unlocked and further locked The control body 29 is driven in the unlocked position direction and the flap 24 is driven in the retracted position direction.

As for the pressure-beared valve 30b of the flap locking body 30, the free end of the flap 24 is mounted on the sloped body 25 after returning to the setting position of the sloped body 25, and in this state, the flap locking body The rotational driving for 30 is set to stop, and as described above, in the state where the platform 4 is returned to the standby position, the wheelchair 16 passes through the slope 25 and the flap 24 to the upper floor. You can get on and off smoothly from the bottom 1 on the side.

A modified example of the slope body 25 is shown to FIGS. 17A, 17B, 18A, and 18B. In this modified example, the slope body 25 consists of the slope body part 42 which connected the setting roller 25a to the front end, and the protrusion part forming part 43 fixed to the front end of the slope body part 42. . The protrusion forming part 43 is formed by rotatably connecting the roller-shaped operation protrusion 25c to the front end of the housing 43a to which the support roller 25b is connected, as shown in FIG. 17A . Both ends of the manipulation protrusion 25c are inserted through a long hole 43b formed in the housing 43a and are prevented from being pulled out by a nut or the like, and further biased forward by a torsion spring 43c.

Accordingly, in the present modification, when the lifting platform 4 is in the standby position, the roller-shaped operation protrusion 25c contacts the pressure-beared valve 30b of the flap lock body 30 as in the above-described embodiment. .

Further, when the platform 4 is raised from the hanging posture shown in Fig. 18A, the relative positions of the platform 4 and the slope body 25 deviate from the set value due to the accumulation of the dimensional error, and from the operation protrusion 25c. The length of the perpendicular line that the operating force to the pressure-beared valve 30b is lowered by, for example, the direction of the rotation center C30 of the flap lock body 30 or from the rotation center C30 to the direction line of the operating force ( moment arm) may become short, and in this case, since sufficient rotational operation force cannot be provided to the flap lock body 30, there exists a possibility of impairing smooth operation|movement.

However, as in the present modified example, if the manipulation protrusion 25c is allowed to move freely within the elongated hole 43b, even in the case as described above, the manipulation protrusion 25c moves backward along the elongated hole 43b to be pressurized. Since the contact angle to the pressure valve 30b is changed, the moment arm becomes large, smooth operation is ensured.

The platform 4 configured as described above is held in the standby position using the platform holding mechanism 32 .

As shown in FIG. 19, the elevator holding mechanism 32 includes a stopper 33 formed around the standby position, and a hook member 34 that is engaged/unlocked by the stopper 33; , and a locking member 20 that controls the hooking/unlocking state of the hook member 34 .

In this example, the stopping part 33 is formed by a U-shaped bolt, and a total of four are fixed to the front and rear wall surfaces of a pair and two guide posts 14 (refer to FIG. 4 ) arranged in left-right symmetric positions, respectively. . The hook member 34 and the lock member 20 are disposed on the elevator platform 4 corresponding to each of the lockable portions 33, and are provided with two hooks for each guide post 14, a total of four hooks. The member 34 and the locking member 20 operate in an operating plane parallel to the front and rear wall surfaces of the guide post 14 .

The hook member 34 is freely rotatable between the locking position shown in FIG. 20A and the unlocking position shown in FIG. 20C around the rotation center C34, and is locked at the upper end of the hooked position. A locking hook portion 34a that is locked to the stopper 33 is provided, and an interference projection 34b is provided at an opposing position of the locking hook portion 34a.

As shown in Fig. 20D, the interference protrusion 34b has a relative movement path of the latched portion 33 when the hook member 34 is in the unlocking position, that is, the lifting platform 4 moves when lifting. It is disposed on the relative movement path of the stopping part 33 .

Therefore, in this example, when the platform 4 is raised from the state of FIG. 20D , first, the stopper 33 collides with the interference projection 34b of the hook member 34, and the hook member 34 is driven rotationally to the locked position. By the rotation of the hook member 34 to the locking position, the hook portion is positioned above the lockable portion 33 as shown in FIG. 20A , and is locked by the lockable portion 33 .

Further, a hook-side protrusion 34c is provided to protrude from an edge on the unlocking position side of the hook member 34 . The hook-side protrusion 34c and the locking surface of the lock-side protrusion 20a, which will be described later, are formed by an arcuate surface centered on the rotational center C20 of the locking member 20 .

In the locked state with the stopped part 33, a rotational force in the lock release direction is generated in the hook member 34 due to the weight of the lifting platform 4, and in order to resist this rotational force and maintain the locked state, A locking member 20 is arranged.

The locking member 20 is disposed adjacent the unlocking side edge of the hook member 34, is rotatable between the locked position of FIG. 20A and the unlocked position of FIG. 20C, and in the locked position, the hook member ( A lock-side protrusion 20a protruding from the edge of the 34) side is engaged with the hook-side protrusion 34c of the hook member 34 . The locking member 20 and the hook member 34 are connected by a tension spring 35, which holds the locking member 20 in the locked position when the hook member 34 is in the locked position. biased to the side.

When a rotational force in the unlocking position direction (clockwise in FIG. 20A) is generated in the hook member 34 while the locking-side protrusion 20a is locked to the hook-side protrusion 34c, the locking member 20 is A compressive force directed toward the rotation center C20 is generated, and the hook contact portion 20b formed on the edge of the hook member 34 side contacts the hook member 34 .

The position of the contact portion of the hook contact portion 20b to the hook member 34 is the region to which the lock member 20 approaches when the hook member 34 moves to the unlocked position, i.e., in this example, the lock member 20 is set above the rotation center (C20) of

Therefore, in this example, even if a rotational force in the unlocking position direction is generated in the hook member 34 due to the load of the lifting platform 4, the pressing force of the lock-side protrusion 20a and the edge of the hook member 34 corresponding to it. only increases, the hook member 34 does not rotate, and the locked state, that is, the holding state of the elevator platform 4 at the standby position is maintained.

From this state, when the locking member 20 is rotated to the unlocking position, the lock-side protrusion 20a moves on the arc surface of the hook-side protrusion 34c, and the lock with the hook-side protrusion 34c is released, The platform 4 starts descending. As shown in Figs. 20B and 20C, the locking of the hook member 34 with the stopable portion 33 is released, and further, the hook member 34 is held in the unlocked position while the locking member 20 is held in the unlocked position. ) is further pulled toward the unlocking position side by the tension spring 35 , so that the hook-side protrusion 34c of the hook member 34 is locked to the end 20c of the lock member 20 .

This state is an unlocked state, since the path of movement of the locking member 20 to the locked position side is obstructed by the hook member 34 once the hook member 34 is latched to the end 20c, the unlocked state is held

As described above, thereafter, when the lifting platform 4 rises and the hook member 34 is stopped by the stopper 33, the locking member 20 is moved to the locking position by the tension spring 35 and , then the lock state is held.

21, 22A, 22B, 23A, and 23B show modified examples of the platform holding mechanism 32 . In addition, in the figure, the same code|symbol is attached|subjected to the component substantially similar to embodiment mentioned above in FIGS. 21, 22A, 22B, 23A, 23B, and description is abbreviate|omitted.

In this modified example, the rack groove 14a is formed in the front and rear wall surfaces of the guide post 14, and the pinion of the bracing device 17 is formed in the rack groove 14a formed in the front wall surface indicated by the arrow in FIG. (17b) is engaged. In this way, by arranging the rack groove 14a on the front and rear wall surfaces of the guide post 14, that is, on the short side, the short side has higher rigidity than the long side, and the amount of deflection is small, so the engagement accuracy with the pinion 17b. is increased to enable smooth operation, and the overall strength can be increased.

In addition, in Fig. 21, 15a denotes a wire for hanging the weight 15, and 15b denotes a pulley.

In addition, the elevator holding mechanism 32 operates in a plane parallel to the wall surface adjacent to the wall surface where the rack groove 14a of the guide post 14 is formed to engage/unlock the stopper part 33 . formed possible.

As shown in FIGS. 22A and 22B , the elevator holding mechanism 32 in the present modified example includes a hook auxiliary member ( ) in addition to the above-described hook member 34 , lock member 20 , and tension spring 35 . 44) is installed. The hook member 34 and the lock member 20 are provided with a hook-side protrusion 34c and a lock-side protrusion 20a, similarly to the above-described embodiment, so as to be freely rotatable around the rotation centers C34 and C20. 4), and operates in the same manner as in the above-described embodiment, and the locking members 20 are connected to each other by the actuating rod 36 .

The hook auxiliary member 44 is free to rotate relative to the hook member 34 on the same axis as the hook member 34, and has a hook-shaped contact protrusion 44a at the rear end that can be contacted with the stopper 33. ) is provided, and an operation wall 44b is provided at the front end, and a long hole 44c for avoidance is formed in the middle portion.

The long hole for avoidance 44c is formed in an arc shape centered on the rotational center C34 of the hook member 34, and the rotational shaft forming the rotational center C20 of the locking member 20 has a curvature through which it can be inserted. formed with

Further, the actuating wall 44b is located above the actuating protrusion 20d protruding from the locking member 20, and is formed at a position capable of contacting the actuating protrusion 20d.

As shown in FIG. 22A , when the hook member 34 is in the locked state, the contact protrusion 44a of the hook auxiliary member 44 is located slightly above the stopped portion 33 . When the locking of the hook member 34 to the stopper 33 is released and the elevator 4 starts to descend, the contact protrusion 44a of the hook auxiliary member 44 to the lockable portion 33 is is in contact, and as shown in FIG. 22B , the hook auxiliary member 44 rotates clockwise so that the rotation axis of the lock member 20 moves relative to the inside of the long hole for avoiding 44c.

Since the actuating wall 44b presses the actuating projection 20d of the locking member 20 in accordance with the rotation of the hook auxiliary member 44, the locking member 20 is rotationally driven to the end-of-stroke position on the unlocking side. do.

In addition, a counterclockwise biasing force is applied to the hook member 34 and the hook auxiliary member 44 by a torsion spring (not shown), and the lock by the hook member 34 is released to release the elevator platform 4 . When is descending, it returns to the initial posture shown in Fig. 22A.

On the other hand, when the lifting platform 4 is raised, as shown in FIG. 23A , first, the contact protrusion 44a of the hook auxiliary member 44 comes into contact with the stopper 33 and rotates clockwise. With the rotation of the hook auxiliary member 44, the locking member 20 has the actuating projection 20d pressed downward by the actuating wall 44b of the hook auxiliary member 44, as shown in Fig. 23B, hook Rotating toward the release position side, the interference projection 34b of the hook member 34 comes into contact with the stopping portion 33, and then, the hook member 34 is hooked by the force applied to the interference projection 34b. Move to the stop position.

As described above, in the present modified example, when the lifting platform 4 rises and moves to the standby position, the hook member 34 and the stopper 33 do not collide, so damage to the hook member 34 does not occur. can be reliably prevented from occurring.

The operation of the locking member 20 is performed by the converting portion 23 connected to the locking operation portion 21 disposed on the handrail 7 as described above.

As shown in FIG. 19 , the conversion unit 23 connects between a pair of opposing locking members 20 , and an operation rod disposed along the wall surface forming the rack groove 14a of the guide post 14 . (36) and an opening lever (37). At the central portion of the actuating rod 36 in the longitudinal direction, the actuating rod 36 is formed in a cylindrical shape through which the actuating rod 36 can be freely inserted, and collars 38 having flanges 38a formed at both ends are mounted.

As shown in FIGS. 19 and 25, the release lever 37 has a mounting piece 37a and a lifting piece 37b formed by bending a plate material into an L-shape, and from the mounting piece 37a to the hoisting platform 4 ) is rotatably connected to the lever bracket 39 fixed on it.

The release lever 37 is disposed in a posture in which the lifting piece 37b is perpendicular to the actuating rod 36, and the lifting piece 37b has approximately the outer periphery of the collar 38, as shown in FIG. 24B. A rod locking portion 40 having a long hole shape having an arc-shaped locking end 40a in contact over half is formed. The opposite end of the rod stopper 40 to the stopper end 40a is formed with a downward opening 40b for providing an opening for insertion of the collar 38 when mounted on the collar 38 .

As shown in Fig. 24A, the rotation center C37 of the opening lever 37 is arranged slightly near the center of the platform 4 from the operation rod 36, and is opposite to the center of rotation C37 interposed therebetween. The inner wire 22b of the wire device 22 is connected to the .

The wire device 22 is arranged along the surface of the platform 4 and at an appropriate height on the platform 4 , parallel to the rungs 7b of the handrail 7 , ie the actuating rod 36 , and the handrail 7 ), the inner wire 22b is pulled in the direction of the lock operation unit 21 , and as shown in FIG. 25A , the opening lever 37 rotates around the rotation shaft C37. As the opening lever 37 rotates, the locking end 40a of the rod stopper 40 moves forward, and is pressed against the locking end 40a so as to be pressed against the collar 38, and the collar 38 The actuating rod 36 inserted into the hoistway moves toward the center of the platform 4 by a predetermined distance δ from the initial position.

The movement distance δ corresponds to the actuation stroke of the locking member 20 from the locking position to the unlocking position, as a result of which the locking member 20 moves to the unlocking position, and The locking state to the locking part 33 is released, and the lowering of the elevator platform 4 is started.

In addition, since the flange 38a of the collar 38 is biased toward the initial position by the compression spring 41, when the operation force to the lock operation portion 21 is released after the release operation on the lock member 20, the compression spring ( An operating force in the direction of the initial position is generated in the collar 38 by the restoring force of 41).

The straight portion 40c (refer to FIG. 24B ) connected to the locking end 40a of the rod locking part 40 is formed in a slightly inclined shape by adding a component in the vertical direction during operation of the locking member 20 . As much as possible, since the lever bracket 39 is installed at an angle, the collar 38 passes the straight portion 40c of the rod stopper 40 and returns to the initial position, so that the opening lever 37 is moved to the initial position. returns to (see Fig. 25b). By the return of the opening lever 37 to the initial position, the inner wire 22b of the wire device 22 is also driven to the initial state side, and the lock operation section 21 also returns to the initial state.

Thereafter, when the locking operation to the stopable portion 33 is generated by the hook member 34 , the locking member 20 moves to the locking position side, and thus the operation rod 36 moves as described above. and the conversion unit 23 returns to the initial state shown in FIG. 19 .

Another embodiment of the present disclosure is shown below in FIG. 26 . In this example, the rack groove 14a is formed on the rear wall surface of the guide post 14 so that the pinion 17b (not shown) of the arming device 17 (not shown) engages, and furthermore, the guide post 14 of On the left and right side wall surfaces, a hook member 34 and a pair of lockable portions 33 constituting the platform holding mechanism 32 in cooperation with the locking member 20 are fixed at opposing positions.

The hook member 34 and the lock member 20 are disposed on the elevator 4 corresponding to each of the lockable portions 33, and have a surface parallel to the left and right side wall surfaces of the guide post 14, respectively. It rotates as a working surface.

The hook member 34 is freely rotatable around a rotation center C34 between the locking position shown in FIG. 28A and the unlocking position shown in FIG. 28C, and at the upper end, the hook member is locked in the stopping position. A locking hook portion 34a that is locked to the stopper 33 is provided, respectively, and an interference protrusion 34b is provided at a position opposite to the locking hook portion 34a.

In this example, when the platform 4 is raised from the state in Fig. 28D, first, the interference projection 34b of the hook member 34 collides with the stopper 33, and then the hook member 34 ) is rotationally driven to the stopping position, and is locked in the stopping part 33 as shown in FIG. 28A .

The locking member 20 is disposed adjacent to the hook member 34 so that it is free to rotate about the center of rotation C20 in the same plane as the working surface of the hook member 34, and the hook member 34 is in the locking position. When present, the hook-side protrusion 34c of the hook member 34 is engaged with the lock-side protrusion 20a of the locking member 20 .

Further, when the hook member 34 is in the locking position, a rotational force in the lock release direction is generated in the hook member 34 due to the weight of the lifting platform 4, whereas the locking member 20 is a hook contact portion. The counterclockwise rotation of Fig. 28A is regulated by 20b contacting the hook-side protrusion 34c of the hook member 34, and the lock-side protrusion 20a is pressed against the hook-side protrusion 34c in a clockwise direction. Since the rotation of is also regulated, it stays in the position of Fig. 20A, as a result, the locking member 20 is held in the locked position.

From this state, when the locking member 20 is rotated clockwise in FIG. 28A, that is, toward the unlocking position side, the hook member 34 does not receive support by the lock-side protrusion 20a, as shown in FIG. 28B. , rotates in the direction of the lock release position to release the lock with the stop portion 33, and the elevator platform 4 starts descending.

In order to smoothly perform the unlocking operation of the hook member 34 by the locking member 20, the contact surface of the locking-side protrusion 20a and the hook-side protrusion 34c has a rotational center C20 of the locking member. It is formed by a circular arc surface centered on it.

Furthermore, since the hook member 34 and the lock member 20 are connected by the tension spring 35, the hook member 34 moves to the unlock position according to the rotation operation of the lock member 20 to the unlock position. , and as shown in FIG. 28C , the hook-side protrusion 34c is stopped by the end 20c of the locking member 20 .

This state is an unlocked state, since the path of movement of the locking member 20 to the locked position side is obstructed by the hook member 34 once the hook member 34 is latched to the end 20c, the unlocked state is held

In order to operate the locking member 20, a pair of locking members 20 corresponding to both side walls of each of the guide posts 14 are connected by an actuating rod 36, as shown in FIG. In addition, the other end of the inner wire 22b of the wire device 22 having one end connected to the lock operation unit 21 is connected to the central position of the operation rod 36 (see FIGS. 30A and 30B ).

so that the operation direction of the inner wire 22b, precisely the direction of operation force applied to the operation rod 36 by the inner wire 22b, is located in a plane parallel to the operation surfaces of the hook member 34 and the lock member 20. , a wire guide 45 is installed on the lift 4 .

Furthermore, a compression spring 45a is mounted between the outer cable 22a of the wire device 22 fixed to the wire guide 45 and the inner wire 22b connected to the operation rod 36, and the inner wire A biasing force is applied to 22b to draw it out toward the end side connected to the actuating rod 36 . As a result, when the platform 4 rises from the lower floor and returns to the standby position, and the hook member 34 shifts to the locking position, the inner wire 22b is pulled and the lock operation unit 21 is in its initial state before operation. return to

The hook member 34 and the locking member 20 are disposed along the left and right sidewalls of the guide post 14 , and the wire device 22 is positioned at the center of the operation rod 36 connecting between the locking members 20 . By connecting, the connecting end of the wire device 22 to the actuating rod 36 is approximately coincident on the widthwise centerline of the guide post 14, as shown in FIG.

As a result, since the bending curvature of the wire device 22 drawn out from the wire lead-out opening 7f of the handrail 7 can be increased compared to the case shown in FIG. 5, the contact resistance at the time of wire operation becomes small, It becomes possible to transmit the operating force smoothly.

Further, in this example, as shown in FIGS. 31 and 32 , at the front end of the handrail bracket 6 , which rotatably connects the handrail 7 , the lock operation member 46 rotates around the center of rotation C46 . In addition to being freely connected, a moving passage 19 is formed in each of a pair of opposing blade pieces 6c of the handrail bracket 6 at opposite positions, respectively, and a first tension spring 12 and a second tension spring 13 are formed. ), both ends of the handrail locking body 8 pulled by the movement is inserted freely.

The first tension spring 12 and the second tension spring 13 are arranged so that the handrail locking body 8 is biased in the direction of the end position of the interference path 47 side of the moving passage 19 to be described later, In the example, one end of the second tension spring 13 is connected to the position of the rotation center C46 of the lock operation member 46 .

The moving passage 19 has an interference path 47 that interferes with the movement trajectory of the lower end of the handrail 7 (the lock operation piece 7c), and a non-interfering path 10 that does not interfere with the movement trajectory. Forming an L-shape, when the handrail 7 is in the standing posture, and the handrail locking body 8 is positioned on the interference path 47, the falling motion of the handrail 7 from the standing posture is regulated, and the non-interfering path ( 10) Rolling motion of the handrail 7 is permitted when positioned within. Further, as shown in Fig. 34A, a locking position is set in the vicinity of the end position on the side of the interference path 47 of the moving passage 19, and a locking evacuation position is set in the vicinity of the end position of the non-interference path 10. As shown in FIG.

31, the lock operation member 46 connects a pair of side pieces 46a along the inner wall surfaces of a pair of opposing wing pieces 6c of the handrail bracket 6 to a connecting piece 46b. It is formed by protruding the driven piece 46c from each side piece 46a toward the center in the width direction. Each of the side pieces 46a has a first stopper side 46d, a second stopper side 46e, an operation valve 46f, a pressure valve 46g, and a valve connecting the operation valve 46f and the pressure valve 46g. An intermediate side 46h is provided.

The locking operation member 46 has an initial position in which the first stopper side 46d is brought into contact with the operation member stopper wall 6d of the handrail bracket 6, as shown in FIGS. 33A and 33B, and FIG. 35A, As shown in 35b, rotation operation is possible between the operating positions in which the second stopper side 46e is brought into contact with the operation member stopper wall 6d.

As shown in Fig. 33A, when the handrail 7 is pressed by the cover body 5 and is in the fall posture, the lock operation member 46 moves the handrail 7 to the fall posture, as will be described later. Depending on the change, it is driven to the initial position. In this state, the operating side 46f is given a clockwise rotational force in Fig. 33A by the biasing force applied to the handrail locking body 8, and as a result, the first stopper side 46d is moved to the operating member stopper wall 6d. ), and the lock operation member 46 is held in the initial position while preventing the occurrence of rattling and the like.

When the cover body 5 is opened from this state, the handrail 7 rotates in the standing posture direction as shown in FIG. 33B by the restoring force of the torsion spring 7d. As the handrail 7 rotates, the handrail locking body 8 is pressed down by the lower end (locking operation piece 7c) of the handrail 7 to open the rotational trajectory of the handrail 7, so that the handrail ( 7), as shown in FIGS. 32 and 34A, can be shifted to a standing posture in which the lower end of the handrail 7 is in contact with the handrail stopper 6e formed on the handrail bracket 6 .

In the standing posture of the handrail 7, the handrail locking body 8 comes into contact with the front surface of the locking operation piece 7c of the handrail 7 in the counterclockwise direction in FIG. 34A of the handrail 7, that is, in the fall direction. Since the rotation of the handrail 7 is regulated, even if a force in the falling direction is applied to the handrail 7, the handrail 7 does not fall over.

From this state, as shown in Fig. 34B, when the locking operation member 46 is rotated from the initial position to the operating position side by pulling up the connecting piece 46b, the handrail locking body 8 becomes the locking operation member 46. It is pushed down by the operation side 46f of , and moves from the interference path 47 into the non-interference path 10 . Thereafter, when the locking operation member 46 is further rotated to an operating position where the second stopper side 46e comes into contact with the operation member stopper wall 6d, as shown in Fig. 35A, the handrail locking body 8 is locked. It is pushed down by the pressure valve 46g following the operation valve 46f of the operation member 46, and moves to the lock and evacuation position.

In the locking and evacuation position, the handrail locking body 8 is press-contacted to the pressure valve 46g of the lock operation member 46, and the lock operation member 46 is subjected to a component force in a direction perpendicular to the pressure valve 46g at the pressure contact position. ) generates a clockwise rotational moment in Fig. 35A, that is, a rotational force for pressing the second stopper side 46e to the operating member stopper wall 6d, and the locking operating member 46 is in the operating position, the handrail locking The sieve 8 is held in a state in which each stayed in the locked and evacuated position.

With the handrail locking body 8 remaining in the locking evacuation position, movement of the handrail 7 in the fall direction is permitted, and the handrail 7 rotates in the fall direction according to the closing operation of the cover body 5 . As shown in Fig. 35b, when the handrail 7 rotates in the falling direction, the lower end of the handrail 7 comes into contact with the driven piece 46c, and further when the handrail 7 falls, the lower end of the handrail 7 The driven piece 46c is pressed by the lock operation member 46 to return to the initial position.

The handrail locking body 8 moves to the locking position side following the return operation of the locking operation member 46, and the operating side 46f, the pressing valve 46g, and the intermediate side 46h of the handrail locking body 8) functions as a cam for determining the movement timing of the handrail locking body 8 so that interference with the handrail 7 does not occur.

The evacuation apparatus of the present disclosure can be used when evacuating a resident or the like in case of a fire in a building.
