The platform 5 includes a distal end side intermediate portion 5a12 of the left end surface portion 5a1 of the proximal end side half 5a,
A lock pin (not shown) that protrudes and protrudes by a central lever 23 is provided in the front end side intermediate portion 5a22 of the right end surface portion 5a2, and one of these lock pins is provided in a lock hole facing the left vertical column 19. The other of the lock pins is fitted into a lock hole (not shown) of a lock bracket 24 provided integrally with the right vertical support shaft 20, and the whole is integrally coupled.

  When the platform 5 is lying down, the upper end 25a is supported by the support shaft 26a and the lower end 25b is supported by the support shaft 26b on the upper portion of the left vertical support column 19 and the upper portion of the right vertical rotation shaft 20. The left and right end surface portions 5a1 and 5a2 of the left end surface portion 5a1 and the base end portion 5a21 of the right end surface portion 5a2 are respectively pivotally supported so as to be pivotally folded.

  The platform 5 is supported horizontally with the bi-fold support rods 25, 25 extended. On the other hand, when the platform 5 stands up, the two-fold support rods 25 and 25 are folded and stored together with the platform 5.

  Next, the platform lateral opening lock release device 27 will be described. A grip 29 having a vertical through hole 28 is provided on the upper end surface of the left vertical support column 19, and a lower half is formed on the upper end surface of the grip 29. A malfunction-preventing dish-shaped body 30 formed on a push-in concave surface 30b that is formed in the connecting portion 30a to the through hole 28 and whose upper surface is recessed in the shape of the opposing thumb is formed into the malfunction-preventing dish-shaped body. 30 connection portions 30a are mounted in the through holes 28 of the grip 29 and arranged at the upper end of the grip 29, and the lower end is connected to the upper end of the connecting rod 33 connected to the release lever 32 of the lock fitting 31. Is inserted into the through-hole 28 of the grip from below and the upper surface of the lock release button 34 slightly protrudes from the upper surface of the malfunction-preventing dish 30 and stops. Uni compression spring 35 is made is deployed is interposed.

  In the embodiment shown in the drawing, a decorative colored washer 36 is inserted between the upper end surface of the grip 29 and the upper half of the malfunction-preventing dish 30.

  The grip 29 may be one in which a pipe strut 29a is welded to the upper end surface of the left vertical strut 19 and a rubber grip outer shell 29b is fitted to the outer peripheral surface of the pipe strut 29a. is there.

  The upper end of the connecting rod 33 and the unlock button 34 are connected to each other in such a structure that the upper end of the connecting rod 33 is formed on the screw shaft 33a and the screw hole 34a is opened on the lower end surface of the unlock button 34. It may be combined.

In the embodiment shown in the drawing, the compression spring 35 is connected to a receiving plate 39 provided on the upper end surface of the pipe-shaped collar 37 whose lower end surface is fitted on the outer periphery of the connecting rod 33, and the pipe-shaped collar 37. The lower end surface 37a may be supported by a configuration in which the lower end surface 37a is disposed directly on the upper end surface of the left vertical support column 19 or connected to the receiving seat portion 38 disposed as illustrated .

  In the embodiment shown in the drawing, the lower end portion of the connecting rod 33 is connected to the extension plate 40 by welding, and the lower end bent piece portion 40a of the extension plate 40 is connected to the release lever 32 of the lock fitting 31 with a screw 41a and a nut. It is fixed by 41b.

  In the embodiment shown in the drawings, the lock fitting 31 is composed of a fixed lock plate 31a and a movable lock plate 31b which is linked to the release lever 32 and operates to be locked and free.

  A lock pin 42 that engages with the fixed lock plate 31 a and the movable lock plate 31 b of the lock fitting 31 is provided on the front portion of the left side frame 4.

  Since the platform-side unlocking device 27 is configured as described above, the grip 29 is grasped with the right hand and the unlocking button 34 is pushed downward to release the lock, and the platform is moved to the position of the temporary line shown in FIG. 5 can be opened by rotating about the right-hand vertical rotation axis 20.

Next, retract the platform 5 with the right hand and grip 29 with the right hand until the platform is locked.
In this series of operations, the operation of changing the hand does not occur, so that the platform 5 can be opened and closed easily.

  Further, the lock release button 34 protrudes upward from the depression depression surface 30 b of the malfunction preventing dish 30 disposed on the upper end surface of the grip, and projects slightly more than the upper surface of the malfunction preventing dish 30. Since it is deployed, in the release operation, the lock is not released unless the upper end is pushed into the lowest inner bottom surface of the push-in concave surface 30b by the thumb, so that the certainty of the lock release is ensured.

  In addition, since the lock release button 34 is protected by the malfunction-preventing dish-shaped body 30, even if something touches the upper surface of the grip for some reason, it is received by the upper surface of the malfunction-preventing dish-shaped body 30. Thus, the lock release button 34 is not pushed inward any further, so that there is no malfunction of unlocking and the safety of the lock releasing button 34 is ensured.

  The platform side opening lock release device of the vehicle elevator according to the present invention can release the platform side opening lock while holding the grip with the right hand, and can perform the platform side opening operation with the right hand as it is. It allows easy loading and unloading of light transported items without having to move up and down the platform.
