Abstract
Description
- This invention relates to a unit which serves as a barrier or obstruction for parking spaces.
- Various arrangements have been proposed previously for providing a barrier or obstruction for car parking spaces, in order to reserve these spaces for intended users. These arrangements have however suffered from a number of disadvantages, mainly being either difficult to use or of complex construction and requiring electrical power.
- I have now devised a barrier or obstruction unit which is straightforward to use and is of relatively simple construction and does not require connection to an external power source.
- In accordance with this invention there is provided an obstruction or barrier unit for protecting a parking space, the unit comprising an obstruction member arranged to move between raised and lowered positions, an actuator arranged to receive fluid under pressure to move the obstruction from one said position to the other, means for storing said fluid under pressure, valve means arranged to be remotely controlled to allow said fluid to flow from the storage means to the actuator, and means responsive to depression by the wheels of a vehicle to recharge the storage means.
- Preferably the obstruction member is spring-biassed towards its lowered position but is held in its raised position by fluid introduced into the actuator and held against escape. The obstruction member is then lowered by remotely-controlling the valve means to allow fluid to be expelled from the actuator: preferably the expelled fluid flows to a second storage means. In order to raise the obstruction, the valve means is remotely-controlled to allow fluid from the primary storage means to flow into the actuator. It will be appreciated that the primary storage means operates at substantially higher pressures than the secondary storage means. Preferably each storage means comprises a cylinder having a spring-loaded plunger.
- Preferably the recharging means comprises one or more compressible chambers disposed within the unit under a pad over which the vehicle wheels pass. Under compression of these chambers, the fluid within them is forced into the primary storage means. Once the vehicle has passed over the unit, the compressed chambers are restored by receiving fluid from the secondary storage means.
- It will be appreciated that the barrier or obstruction unit of this invention is of relatively simple construction and is straightforward to operate. In particular it does not require connection to an external power source.
- An embodiment of this invention will now be described by way of example only and with reference to the accompanying drawings, in which:
- FIGURE 1 is a perspective view of a unit in accordance with this invention;
- FIGURE 2 is a similar view of the unit with parts cut away to show internal components of the unit; and
- FIGURE 3 is a section through the unit showing details of a pivoted obstruction member of the unit.
- Referring to the drawings, there is shown a unit which serves as a barrier or obstruction to protect a reserved car parking space. The unit comprises a flat, generally
rectangular body 10 for bolting in place on the ground, and atriangular obstruction member 12 which is hinged adjacent the front edge of the flat body 10: in use themember 12 pivots between a raised position (shown in Figure 1) and a lowered position, in which it lies flat on the top of thebody 10. The top of thebody 10 is formed with a rectangular aperture into which aflexible pad 14 is fitted, for a purpose which will be described below. The edges of thebody 10 are chamfered as shown. - A
strut 16 is hinged at one end to a mid-point of theobstruction member 12 and at its other end to the piston of anactuator cylinder 18 which is positioned within thebody 10, extending from front-to-rear of the latter. Aspring 20 acts on the lower end of thestrut 16 and urges this end of the strut rearwardly of the unit, so as to bias themember 12 towards its lowered position, flush with the top of thebody 10. - As shown in Figure 2, the interior of
actuator cylinder 18 is connected via two solenoid-operatedvalves way valves respective storage cylinders 25,26: it will be noted that one-way valves compressible chambers 27 are positioned under theflexible pad 14 of the unit, and are connected together and via oppositely-directed one-way valves storage cylinders electronic control system 30 for thesolenoid valves 21,22: the car driver authorised to use the parking space has a controller for remotely operating the unit. Preferably the unit includes a solar panel arrangement for recharging the batteries of theelectronic control system 30. - In use, suppose the
obstruction member 12 is in its raised position: at this time, theactuator cylinder 18 is filled with fluid under pressure so as to hold its piston in its retracted position against the bias of thespring 20, and thesolenoid valves cylinder 18. When the authorised car wishes to park, the driver remotely operates thecontrol system 30 to open the solenoid valve 21: fluid then flows from within thecylinder 18 via one-way valve 23 and into thestorage cylinder 25, as thespring 20 acts to extend the piston of theactuator cylinder 18 and lower theobstruction member 12. Thesolenoid valve 21 then closes. - The driver is then able to drive over the unit: in so doing, the car wheels ride over the
flexible pad 14 and compress thefluid chambers 27; this expels fluid from thecompressed chambers 27, and this fluid passes via the one-way valve 29 into thestorage cylinder 26. The latter cylinder comprises a spring-loaded plunger which is depressed as the fluid is forced into the cylinder. - Once the driver has parked his car, he is able to raise the
obstruction member 12 by remote control: this openssolenoid valve 22 and the pressurised fluid withinstorage cylinder 26 then flows via one-way valve 24 andsolenoid valve 22 into theactuator cylinder 18; the fluid fromstorage cylinder 26 is at such a high pressure that the bias ofspring 20 is overcome and themember 12 is raised. Thesolenoid valve 22 then closes. - When the
obstruction member 12 lowers, fluid from theactuator cylinder 18 flows to thestorage cylinder 25 and stored in that cylinder at relatively low pressure. After thechambers 27 have been compressed by the car wheels, the pressure withinstorage cylinder 25 is however sufficient to replenish the fluid withinchambers 27 via the one-way valve 28.
