suitable. Since the bottom of the conventional chocks is only 1

with individual studs or steel spikes* \

I have therefore designed a safety chock which · f

is also specially equipped for winter. I

&ngr; r

All suitable materials are taken into consideration for the design of the safety chock, primarily steel and high-quality special cast iron in cast or welded versions, as well as high-quality light metals or alloys. 1

The safety chock is also provided with a handy handle (see Fig. .1 Be^). (I), this handle facilitates
pulling out the safety chock from the underlay
Wheel. Furthermore, Fig.2 shows a see-through representation, length
of the safety chock = 34cm. see reference AB, width = 15cm
see reference (D).The pitch of the safety chock is in
usually between 30-45 %, and depends on the dimension
or radius of the tire .

The underside of the safety chock is completely fitted with OTm long steel pins, see Fig.2 (ref.C). These steel pins are particularly suitable for icy and slippery roads. The safety chock is also provided with a retro-reflective coating on the 2 side walls and on the front side, see Fig.1 (ref.K). The safety chock is also provided with orange warning lights on the 2 side walls and on the front side, see Fig.1 (ref.H).

These two devices provide additional safety, e.g. for parked trucks in the dark and with poor visibility, in fog, as the safety chock also protects the truck from both sides and from the rear thanks to the reflective coating provided and the 3 orange warning lights provided. The running surface of the safety chock is provided with anti-skid ribs, see Fig.4 Ref»(G) Dimensions of the ribs Width = 5mm, length = 15cm, height = 5mm. When the tire is rolled up on the running surface, the anti-skid ribs penetrate the tire profile, which gives the tire better grip on the chock. The contact surface must be designed so that the wheel can roll up easily and rest securely so that the safety chock is loaded with a portion of the vehicle's weight and pressed onto the road. The steel studs thus penetrate the icy road surface and prevent the loaded safety chock from slipping away. The distance from rib to rib see Fig. 1(

is intended to be 2-3cm.

There are different standards for wheel chocks, the width, length and height depend on the dimension or radius of the tire. An ideal wheel chock is therefore adapted to the tire shape and can ensure optimal safety on slippery and icy roads thanks to the attached safety anti-skid tips.

As already mentioned, anti-skid tips are formed on the underside of the chock; these penetrate the road surface and prevent the loaded chock from slipping. The safety chock (see Fig. 3-k) is also shown in side view and front view and is provided with a reflector coating (see reference (K).

The reflector coating is glued on with special glue and serves as an additional safety feature. In addition, three orange warning lights, each with 21 watts, are built into the safety chock inside the space between the two ₍ see Eez.(H) and Bez.(J) shows the 12 volt connection socket, the power is fed from the nearest power connection switch on the truck to the chock using a connection cable. A door with hinges and a lock is also provided, see Fig.3 (BZ G and BZ F). The door serves as an internal access to the flashing light system in the event of a defect. These three built-in warning lights and the reflector coating provided provide extra safety in the dark and when visibility is poor when the vehicle is parked.

Heavy goods vehicles, with this safety wedge underneath with triple safety effect.

Claims (1)

1. Metal safety chock for trackless vehicles with elastic tires, primarily for trucks, buses, etc. Features: b) the underside of the safety chock is completely equipped with 5mm long steel pins, c) the steel pins are molded into the safety chock, c) the steel pins can also be screwed on, so that the worn steel pins can also be replaced, d) since the entire underside is provided with safety steel pins, the safety of the parked truck on an uphill icy road is increased, e) a handy handle is also provided for pulling out the safety chock. 2* The safety chock is also provided with a reflector coating made of metal foil or plastic on both side walls and on the front. Features: f) this reflector coating serves as an additional safety effect in the dark and in poor visibility, as the parked truck, for example, can be seen better from the side as well as from behind thanks to the reflector coating on the safety chock. 3. The safety chock is also equipped with three orange warning lights. Features: g) this warning light device serves as even more safety, h) this safety chock secures, especially in the dark and in poor visibility, the parked truck, for example, from the side and from behind^ I5- I Fatentaaspruche Aktz.G8712 j before a rear-end collision, as the truck is protected by this device 4 is spotted more closely. f k.
