Abstract
An access lift platform, such as for accessing or loading vehicles, comprises a bridge plate restraint mechanism 4 which comprises of a shaft with a right angle restraint peg 9, this restraint mechanism is connected to, and operated by, the safety gate 6 in such a way that as the safety gate 6 is folded away the right angle restraint peg 9 is rotated over the stowed bridge plate 3 to secure it. The bridge plate 3 pivots on the platform 1 on pivots 2 and is shown in the stowed position. The restraint mechanism 4 may be clipped 5 or bolted to the safety gate.
Description
Improved Bridge Plate Restraint Mechanism for Vehicle Access Lift Platform Access lifts are well known within the vehicle industry. They can be used for a wide range of loading applications which can include passengers and or freight.
The purpose of the access lift is to raise or lower either goods and or passengers from ground level to the vehicle floor height or vice versa.
In some applications it is necessary to fit a bridge plate at the end of the platform. This is to bridge the large gap between the end of the platform and the vehicle floor. On some lifts the bridge plate is manually deployed. One problem with this arrangement is that after use the bridge plate needs to be stowed and secured before the platform can be folded away.
One successful method for securing the stowed bridge plate is to use the hinge down safety gate to fold over the bridge plate and secure it. However on some applications the safety gate dimensions and or position preclude this arrangement. In this situation various methods have been tried for securing the stowed bridge plate including a shoot bolt mechanism. All of these methods have been problematic and unreliable.
According to the present invention there is provided a bridge plate restraint mechanism which comprises of a shaft with a right angle restraint peg. This restraint mechanism is connected to, and operated by, the safety gate in such a way that as the safety gate is folded away the right angle restraint peg is rotated over the stowed bridge plate to secure it.
Preferably the bridge plate restraint mechanism is made from a combination of steel, aluminium and rubber, but it can be made of any structural material or a combination or materials which are suitable to meet the specification.
A preferred embodiment of this invention will now be described by way of example with reference to the accompanying drawings in which: -Figure 1 shows in perspective the access lift platform with the safety gate and bridge plate in the deployed position Figure 2 illustrates in perspective the access lift platform with the bridge plate in the stowed position and with the safety gate in the process of being folded away.
Figure 3 illustrates in perspective a view of the access lift platform with the safety gate in the fully folded down position and with the peg of the restraint mechanism holding the bridge plate securely in the stowed position.
Figure 4 illustrates in perspective the key elements of the bridge plate restraint mechanism.
Referring to Figures I -the bridge plate 3 is attached to the platform I by two pivot plates 2 so that the bridge plate 3 can be manually rotated 180 degrees, from the deployed position to the stowed position. The bridge plate restraint mechanism 4 is operated by, and is connected to the safety gate 6 by a simple connecting clip 5 Refemng to Figure 2 -the bridge plate 3 has been manually rotated 180 degrees to the stowed poison. It is held in this position by the restraint peg 9 of the bridge plate restraint mechanism 4 which is operated by Safety gate 6 as it is folded down onto the platform Referring to Figure 3 -the safety gate 6 is fully folded away and the bridge plate 3 is now held securely in the stowed position by peg 9 of the bridge plate restraint mechanism Referring to Figure 4 -the bridge plate restraint mechanism 4 pivots about an extended safety gate hinge pin 8 at one end and at the other end, the end bracket pivot 7. The mechanism is connected to the safety gate by a simple "U" shaped connecting clip S which is connected to, and operated by the Safety gate 6 so that the whole mechanism 4 including the restraint peg 9 rotates with the Safety gate 6 as it hinges about the hinge pin 8 so as to secure the bridge plate in its stowed position.
In another embodiment the bridge plate restraint mechanism 4 could be incorporated into the safety gate fabrication so that it operates in a similar manner.
In a further embodiment the bridge plate restraint mechanism 4 could be bolted directly to the Safety gate S.
Claims (8)
- Claims.I An access lift platform bridge plate restraint mechanism which comprises of a shaft with a right angle restraint peg, this restraint mechanism is connected to, and operated by, the safety gate in such a way that as the safety gate is folded away the right angle restraint peg is rotated over the stowed bridge plate to secure it.
- 2. A bridge plate restraint mechanism according to claim I wherein the shaft with the right angle restraint peg is located at the side of the platform and pivots approximately on the same centre line as the safety gate
- 3. A bridge plate restraint mechanism according to claim I and 2 wherein the shaft with the right angle restraint peg is cormected to and operated by the safety gate via a simple "U" shaped connecting clip
- 4. A bridge plate restraint mechanism according to claim 1 and 2 and 3 wherein the shaft with the right angle restraint peg is incorporated into the safety gate, removing the need for the clip.
- 5. A bridge plate restraint mechanism according to claim I and 2 and 3 wherein the shaft with the right angle restraint peg is bolted directly to the safety gate.
- 6. A bridge plate restraint mechanism according to the foregoing claims wherein the shaft with the right angle restraint peg is incorporated into and operated by the safety gate so that the restraint peg is rotated unto the bridge plate to secure it as the safety gate is folded away,.
- 7. A bridge plate restraint mechanism according to the foregoing claims wherein the right angle restraint peg could be spring loaded onto the shaft to provide compliance when restraining the bridge plate
- 8. A bridge plate restraint mechanism according to the foregoing claims wherein the right angle restraint peg could be a coil spring or a leaf spnng to provide compliance when restraining the bridge plate
