Description
I ~ 77~9~
1 FIEI.D OF T~E INVENTION
The present invention relates to a blocking arrangement for preventing unauthorized use of a private parking space such as those found in underground parking areas.
BACKGROUND OF THE INVENTION
Most apar-tment buildings have reserved parking areas specifically for tenants of the building. In many cases these reserved parking spaces are left unattended and accessible to unauthorized use. In many instances, visitors to the building who are unable to find any visitor parking ~ill use the reserved parking spaces if they are not properly guarded.
There are availabele some types of parking space guards. Ho~ever~ these prior art systems, which are generally quite complicated, can present a danger hazard as a result of their rigid nature. The danger can be both in the form of damage to the guard itself and/or to the vehicle. For example, conventional guards could cause severe damage to the fuel tank resulting in fuel leakage and a potential fire and explosion hazard.
SUMMARY OF THE PRESENT INVENTION
The present invention provides an arrangement for blocking a parking space against unauthorized use. The arrangement comprises blocking means, a mounting system for mounting the blocking means at the parking space in a manner such that the blocking means is moveable from an upright blocking position to a generally prone access or drive-over position and locking means for releasably ~0 locking the blocking means in the upright blocking position.

1 The blocking means is provide(i with a springy or flexible portion which may be hidden to eliminate attempted entrance to the parking space, but which allo~,rs bending of the blocking means in the event of inadvertent or otherwise undue force on it when in the blocking position. This mitigates damage to both the guard arrangement and the vehicle while still providing an effective parking space guard.
According to the present invention the reserved parking area can be left guarded by simply locking the blocking means in its upright blocking position which prevents unauthorized use of the parking space. In order to gain access, the authorized user of the parking space simply removes the locking means to lay the blocking means in its prone access position to allow the vehicle to be driven directly over the blocking means into the parking space. If the blocking means is inadvertently or otherwise hit, the spring portion allows deflection which might otherwise cause damage to both the vehicle and the blocking arrangement.

DETAILED DESCRIPTION ACCORDING TQ THE PREFERRED
EM~ODI~IENTS OF THE PRESENT INVENTION
As shown in Figure 1, a reserved parking spot is blocked by a blocking arrangement generally indicated at 1, against use by unauthorized persons. The parking guard which comprises a mounting base plate 3 and an upright blocking portion 5 is located at the entrance to the parking spot and is shown in Figure 1 in its upright blocking position. The parking guard or block can easily be laid down to the Figura 3 position with the proper releasing keys to allow the authorized parker, use of his or her parking spot.
Referring in more detail to Figures 2 and 3, the arrangement comprises a pair of blocking members 7~
secured at their feet 8 to the base plate 3. The feet ~7729C
1 are housed within the base plate in a manner to allow swinging of the blocking members from the blocking position in Figure 2 to a prone position as shown in Figure 3, where the blocking members fold at one another to a relatively flat position directly on the base plate.
The base plate itself is provided with hollowed bosses 13 into which the feet of the blocking members are fitted and locked in position by means of small studs 15. ~he tubular construction of the blocking members and the corre~ponding shaping at the ba3e allows the folding action of the blocking members.
When the blocking members are swung up to the Figure
2 position they form a triangular arrangement having an apex generally indicated at 9. Each of the blocking members has a small opening at the apex for receiving a lock 11, which holds them in the upright triangular position. When the lock i8 removed the two blocking members fold into the region defined between stops 15 and a second set of small bosses 17 on the base plate. Both these bosses and the larger bosses 13 have a ramped shape to prevent catching of the undercarriage of the car on the blocking arrangement.
~ he construction of the blocking members includes springs 10 immediately above the feet of these members.
The remainder of the blocking members above the springs is formed from polyurethane with the springs also being protected and hidden by a polyurethane covering.
According to this arrangement, the blocking members will deflect downwardly if they are hit hard enough when in the upright blocking position. This feature ~ ~ 7729C
1 substantially mitigates possible damage to the structure and the polyurethane construction reduce~ the likelihood of tearing through an automobile gas tank in the event that someone does in fact drive over the structure. As such the structure is extremely effective as a visible impairment to parking in the reserved space and at the same time if someone inadvertently or otherwise does drive into the structure, it will spring back to its blocking position without risking fire and explosion damage otherwise resulting from full leakaee.
The base plate itself is provided with small openings 19 for receiving bolts 21 which are bolted directly into the concrete floor of the parking garage to permanently secure the blocking arrangement at the entrance to the parking space.
Figure 4 shows a blocking arrangement having a single blocking member 23 mounted to a base plate 21. In this arrangement the lower legs 24 and 24a of the blocking member, provided with interior springs and formed from polyurethane above the hidden springs, are pivotally mounted at 25 to a pair of ramps 27 forming part of the base plate. Located at the end of the blocking member, remote from the base plate is a further ramp 29. Each of these ramps is again arranged to cover any areas that might otherwise catch on the undercarriage of the vehicle aæ it drives over the blocking arrangement in the prone position of Figure 5.
Leg 24a of blocking member 23 is fitted with a locking arrangement comprising a pivoting pin 31 and a plate 33 mounted directly on leg portion 24a. 1'he ! J 7729~
1 pivoting pin and the small plate are each provided with a small opening with the two openings aligning with one another when the blocking member is in the Figure 4, uprieht position. When the holes are aligned a lock 35 fits through the pivoting pin into the plate and locks the blocking member against being folded to the Figure 5 position. After the lock i9 removed the pin and plate are moveable relative to one another to allow the blocking member to be laid into its prone position for driving the vehicle into and out of the parking space.
Figure 6 shows an arrangement in which the blocking member itself is identical to that shown in Figures 4 and 5. However, in this arrangement rather than having a single ba,se plate the mounting system for the blocking arrangement includes a pair of base portions 22 with a locking arrangement being located on the lower leg of the blocking member at one of the base portions. This arrangement is somewhat lighter than the earlier svructures and has advantages from a packing and shipping standpoint.
The arrangements described above are particularly suited for indoor use. However, a special mounting system i~ shown in the Figures 7 and 8 arrangement which is more suitable to outdoor use, in that this arrangement is adapted to meet snowplowing requirements.
More particularly, the arrangement of Figure 7 includes a pyramidal base which slopes upwardly and inwardly from all four sides. The base is fitted with a pair of foot pads 34 anchoring a blocking member 32. The foot pads are countersunk in the base which further 1 ~ 7729~
1 includes a recess 36 for receiving the blocking member when it i9 in the down position, as shown in Figures 7 and 8.
This pyramidal recessed base allows snowplowing of the guard when the blocking member is lowered and the structure is covered by snow and not visible. The snowplow will, however, ride up over the base rather than catching on and lifting the base.
The entire unit is stabilized by an insert around the underside of the base having downwardly projecting barbs or prongs 38 which are driven into the asphalt or pavement when the base is bolted in position. ~he bolts themselves have an irregularly shaped head, such as a triangular or oval head, so that they are difficult to remove other than with a specially designed tool which is only available to the person installing and servicing the structure. This, of course, substantially reduces tampering to the structure.
All of the arrangements above are made from a material which will stand up to substantial impacts in the event that they are inadvertantly hit by a moving automobile. They are all extremely effective against guarding a parking spot by simply raising the blocking portion to the upright position where the entire arrangement is highly visible to anyone attempting to make unauthorized use of a parking space. It should be noted that, even though damage prevention springs and polyurethane construction components are provided, these features are not recognizable to an unauthorized person so that the structure remains highly effective as a I ~77~99 1 parking guard. The locking system for any of the arrangments described above i9 readily accessible for a person having the appropriate key or combination to release the lock 80 that the blocking member can be laid down essentially flat to a position where the vehicle i8 very easily driven over the structure to get into and out of the parking spot by authorized persons.
Although various preferred embodiments of the invention have been described herein in detail it will be appreciated by those skilled in the art that variations may be made thereto without departing from the ~pirit of the invention or the scope of the appended claims.
