Abstract

PURPOSE: To push out a lock pole even if the stroke of the lock pole is short by forming a lock pole lifting mechanism with a pole casing, a lock pole liftable in the casing, a telescoping mechanism part, and a towing member. CONSTITUTION: When pressurized fluid F flows into a fluid pressure cylinder C, a piston rod is raised. Subsequently a lifting rod 31 connected to the piston rod is moved upward. Also a first block 33 attached to the lifting rod 31 is raised interlockingly. With this rise, because one end of a first towing member 4 suspended on a fixed base 32 is fixed to the lower part of a lock pole 2, the lock pole 2 is moved upward. In this case, the moving distance becomes approx. twice the amount of rise of the rod 31. Namely the first block 33 functions as a running block to extend the distance. On the other hand, when the lock pole 2 lowers, vice versa. Thus the stroke of the piston rod is halved, and the deterioration of drive parts and troubles due to wear can be reduced, extending the service life of a lock pole lifting mechanism remarkably.

It is a schematic sectional drawing which shows the state which the lock pole went up in the 2nd Example apparatus comprised by applying this invention.

First, a first embodiment device constructed by applying the present invention will be described with reference to FIGS. In the drawing, what is indicated by reference numeral 1 is a bottomed cylindrical pole casing, which is buried in the ground at a predetermined position in the parking area so that the upper part is exposed to the ground surface.

Reference numeral 2 designates a lock pole which is vertically movable inside the pole casing 1 so as to be able to move up and down. The lock pole is controlled in association with a parking meter installed in a parking lot to park a vehicle. Manage permission and denial.

Reference numeral 3 indicates an expansion / contraction mechanism for moving the lock pole 2 up and down, which is an elevator rod 31 and a fixed base 32 installed in the pole casing 1.
It is mainly composed of A first block 33 is attached to the upper part of the lifting rod 31, and the lifting rod 31 is also attached.
A second block 34 is attached to the lower part of the. In this embodiment, a fluid pressure cylinder C is adopted as a drive source for moving up and down the lifting rod 31, and this fluid pressure cylinder C has a cylinder body C1 and a piston rod C2.
(In FIG. 1, it cannot be seen because it is hidden by the lifting rod 31). As shown in FIG. 3, the elevating rod 31 is connected to the upper end of the piston rod C2 by a bolt,
The elevating rod 31 is interlocked with the elevation of the piston rod C2. The fixed base 32 is a cylinder body C
It is attached to the upper part of 1, and one end of a pulling member described later is fixed. In this embodiment, the first and second blocks 33,
Although a sprocket is used as the member of 34, any member having a function of a moving pulley may be used.

Reference numeral 4 designates a first traction member (chain) suspended on the first block 33 of the expansion / contraction mechanism section 3, one end of which is fixed to the fixed base 32.
The other end is fixed to the lower part of the lock pole 2. The first pulling member 4 is a member for raising the lock pole 2.

Reference numeral 5 indicates a second traction member (chain) suspended on the second block 34 of the expansion / contraction mechanism section 3, one end of which is fixed to the fixed base 32.
The other end is fixed to the upper portion of the lock pole 2. The second pulling member 5 is a member for lowering the lock pole 2. In this embodiment, chains are used as the first and second pulling members 4 and 5, but wire ropes formed by twisting fibers and steel wires may be used.

Now, the lifting mechanism of the lock pole 2 in the first embodiment will be described. First, rock pole 2
The mechanism of when is raised is as follows. Fluid pressure cylinder C (In this embodiment, an air cylinder is used.
A fluid pressure pipe T is connected to the hydraulic cylinder or a hydraulic cylinder), and the pressurized fluid F flowing in the pipe T flows into the cylinder C. Then
The pressurized fluid F that has flowed in pushes up the piston rod C2 in the cylinder C, moves the lifting rod 31 connected to the piston rod C2 upward, and at the same time, attaches to the upper portion of the lifting rod 31. 1 block
33 goes up in tandem. With this rise, the first block
Since one end of the first pulling member suspended on 33 is fixed to the lower portion of the lock pole 2, the lock pole 2 moves upward. The moving distance at this time is about twice as much as the rising amount of the elevating rod 31. That is, the lifting rod 31
By making the first block 33 connected to the above function as a moving pulley, it is possible to increase the moving distance.

On the other hand, the mechanism when the lock pole 2 descends is the reverse of the above case. When the pressurized fluid F flows out from the fluid pressure cylinder C, the piston rod C2 in the cylinder C is lowered, the elevating rod 31 is moved downward, and the second block 34 is interlocked and lowered. Along with this lowering, the second pulling member pushes down the lock pole 2, and the entire lock pole 2 is housed inside the pole casing 1 as shown in FIG.

As described above, the stroke of the piston rod C2 in the fluid pressure cylinder C is halved by skillfully utilizing the function of the moving pulley of the expansion / contraction mechanism 3 and the pulling members 4 and 5 for the lifting mechanism of the lock pole. Therefore, failure due to deterioration or wear of the cylinder member is reduced, and the life of the lock pole device can be extended. In addition, the amount of energy required to move up and down is reduced and running costs can be reduced.

Further, since the hollow cylindrical lock pole 2 is used in the device of the first embodiment, the fluid pressure cylinder C, the expansion / contraction mechanism portion 3 and the pulling members 4 and 5 are provided inside the lock pole 2. An extremely compact lock pole device can be constructed that can be stored in a snap ring.

Next, an example in which the above-described first embodiment device is installed in a plurality of parking lots will be described with reference to FIG. In each parking area, a parking meter and a lock pole 2 that manage the movement of the vehicle are installed. A fluid pressure pipe T is connected to each of the fluid pressure cylinders C, C ... that raises and lowers the plurality of lock poles 2, 2, ..., And the fluid pressure pipe T has a fluid pump P (in this embodiment, an air pump). Is connected to the control unit via. A settlement signal from each parking meter is input to this control unit, and the pressurized fluid F is caused to flow into or out of each fluid pressure cylinder C, ... The pole 2 moves up and down appropriately. As described above, only one fluid pump P needs to be used as a power source for moving up and down the lock poles 2 ..., It is not necessary to embed a power source such as a motor in each parking area. Therefore, in addition to the cost reduction due to the movable pulley described above, it is possible to further reduce the cost of the parking lot as a whole.

Further, a second embodiment device constructed by applying the present invention will be described with reference to FIG. The configuration of the device of this embodiment is almost the same as that of the device of the first embodiment, but the lock pole 2
The difference is that a screw jack S is used as a drive source for moving up and down. This screw jack S
Is composed of a screw main body S1, a screw rod S2 screwed into the screw main body, and a geared motor S3 capable of rotating in the normal and reverse directions at a predetermined low speed. By rotating this motor S3 forward and backward, the screw rod S2 (corresponding to the piston rod C2 of the first embodiment device) moves up and down, and the elevating rod 31 connected to this screw rod S2 ascends and descends. . Therefore, the lock pole 2 can be lifted up and down in the pole casing 1 freely, and the same advantages as the first embodiment device can be obtained.

The embodiments of the present invention are generally as described above, but the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims. For example, as the shape of the lock pole,
Not only a cylindrical shape but also a plate shape may be adopted. Further, in this embodiment, two sprockets for raising and lowering are used as blocks, but various combinations of two or more blocks are used. It is also possible to change the fixed positions of both ends of the pulling member suspended on these blocks, and it goes without saying that such a change belongs to the technical scope of the present invention.

[0021]

As described above with reference to the embodiments, according to the present invention, since the stroke of the rod in the ascending / descending drive portion of the lock pole can be reduced by the function of the moving pulley, the failure of the drive portion due to deterioration or wear can be prevented. The number of lock pole devices is reduced, and the life of the lock pole device can be significantly extended. Furthermore, the amount of energy required for lifting and lowering is reduced, and running costs can be reduced. Therefore, the practical value in the pay parking lot becomes great.
