Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a locking device for stabilizing an unfolded elevating platform plate installed at the rear entrance of a vehicle body so that it does not wobble.

Prior Art The inventor of the present invention has previously devised a device in which an elevating platform is installed at the rear entrance of an automobile, and this is folded and stored on one side of the inside of the vehicle body facing the entrance.

Problems to be Solved by the Invention The inventor of the present invention found that the device previously proposed had the disadvantage of poor stability because the base plate was supported in a cantilevered manner. Therefore, separate from the movable arm, an auxiliary movable arm is installed on the other side, a supporting link is passed between both arms, and the first
We devised the idea of mounting an elevating base plate on the pedestal, but since the auxiliary movable arm side of the base plate was simply mounted on the support linkage, when the base plate was unfolded, there would be some movement toward this auxiliary movable arm side. It turned out to be unstable. Therefore, the present invention was made with the aim of preventing this rattling.

Means for Solving the Problem In a foldable elevating platform that can be freely inserted and removed from the entrance at the rear of the vehicle body, both ends are supported at both lower ends of a movable arm on one side and an auxiliary movable arm on the other side. The outer end of the first elevating base plate is mounted on the support link rod, and the edge frame of the first elevating base plate facing the auxiliary movable arm, which is one side of this mounting part, is A movable stopper that fixes a latch and engages and disengages from the latch has its upper end pivoted to an auxiliary movable arm, and a coil spring that brings the lower end of the movable stopper into contact with the upper slope of the latch. is installed on the auxiliary movable arm, and a protrusion for deactivating the movable stopper is provided at a predetermined position on the end surface of the auxiliary movable arm side of the second elevating table plate, which is connected to the outer end of the first elevating table plate by hinges on both sides. A locking device for an interior-type elevating base plate for an automobile, characterized in that a locking device is provided with a locking device.

Function Since the present invention is constructed as described above, the first and second functions are as follows.
When the elevating table plates 3a and 3b are unfolded, the first elevating table plate 3a has the movable stopper 7 on the auxiliary movable arm 2 side.
Since the latch 5 of the first elevating table plate 3a is pressed by the lever, the first elevating table plate 3a is stable without rattling, and the entire elevating table plate 3 is stable. It is possible to get on and off the vehicle without causing anxiety to the disabled persons riding the vehicle. Furthermore, when the second elevating base plate 3b is folded over the first elevating base plate 3a when stored in the vehicle interior, the movable stopper 7 is pressed against the surface of the auxiliary movable arm 2 against the action of the coil spring 9. ,
Since it is automatically released from the latch 5, the first lifting platform 3a and the second
For example, by placing both hands on the elevating platform plate 3b, it can be rotated and raised.

Embodiment To explain the present invention with reference to the drawings, 1 is a movable arm, and 2 is an auxiliary movable arm, which can be pulled into and stored in a vehicle as shown by the chain line in FIG. 1A by operating a hydraulic cylinder, or Grasp the handle and pull it slightly toward you, pull out the links 11 and 12 toward you beyond the vertical line, then, with the elevating platform 3 in an upright position, use hydraulic operation to bring down the links 11 and 12 toward you, as shown in Figure 1b. When the movable arm 1 and the auxiliary movable arm 2 are extended to the state shown by the solid line, they are stopped, and the elevating platform plate 3 is brought down from the standing state to the side.
Expand as shown by the solid line. The elevating table plate 3 is foldably provided from a first elevating table plate 3a, a second elevating table plate 3b, and a third elevating table plate 3c, and as shown in FIG. Lifting platform plate 3b
The third elevating platform plate 3 is foldably connected with the treads connected by the hinge parts 3d, 3d.
c and the second elevating table plate 3b can be folded into the state shown in the dashed line in FIG. 1a and the dashed double dotted line in FIG. established in Reference numeral 4 designates a support link extending between the movable arm 1 and the auxiliary movable arm 2, on which the first elevating table plate 3a is placed horizontally. Reference numeral 5 designates a dogleg-shaped locking ring attached to the edge frame 6 of the first elevating table plate 3a, and a movable stopper 7 that engages and disengages from this is pivotally fixed at the upper part to the auxiliary movable arm 2 by a pin 8. The rear end is pressed into contact with a coil spring 9 supported by the auxiliary movable arm 2, and the lower end is always brought into contact with the upper tapered surface of the dogleg-shaped locking metal 5. 10 is the second elevating table plate 3b
The movable stopper 7 resists the action of the coil spring 9 when the second lifting table plate 3b is folded over the first lifting table plate 3a. The arm is pressed against the surface of the auxiliary movable arm 2, and the lower end is released from the dogleg-shaped latch 5 as shown in FIG.

Effects According to the present invention, when the elevating table plate is unfolded as shown in FIG.
Since the dogleg-shaped latch 5 of the elevating table plate 3a is pressed as shown in FIG. 6, the first elevating table plate 3a is free from wobbling, and the entire elevating table plate 3 is stabilized. Therefore, when descending from the rear exit of the vehicle onto the elevating base plate 3 or entering the vehicle body via the elevating base plate 3, the base plate 3 is stable and does not cause anxiety to a disabled person in a wheelchair. , which has the effect of allowing passengers to get on and off the vehicle. Further, when the second elevating base plate 3b is folded over the first elevating base plate 3a when storing it in the vehicle interior, the actuation release protrusion 10 is removed from the movable stopper 7.
The auxiliary movable arm 2 resists the action of the coil spring 9.
is pressed against the inner surface of the holder and automatically released from the latch 5, so for example, by placing both hands on the first and second elevating base plates that are folded and lying horizontally,
Since this can be rotated and raised without any operation, the heavy lifting platform can be deployed,
This has the effect of allowing storage to be carried out extremely easily and reliably.
