Abstract
A locking device for fixing to a surface includes a base plate having two upstanding flange members (2) spaced apart and facing one another. Each flange member (2) is provided with an aperture (3) which is aligned with a corresponding aperture of the facing flange member. A locking pin passes through the apertures (3) of the flange members (4), with one end (5) of the locking pin (4) being adapted to co-operate with a lock (8) to secure the locking pin (4) in position between the two flange members (2) so that the locking pin (4) cannot be withdrawn. One flange member (2) includes a lock cover (9) which receives the end of the locking pin, the lock cover (9) having an opening (10) which faces the base plate and which provides the only access to the end (5) of the locking pin when it is in position to enable the lock (8) to be secured or released. As the opening (10) in the lock cover (9) faces a fixed base plate there is insufficient space to insert a tool to force the lock and thereby enable the locking pin to be withdrawn. Only a person who possess the correct means for releasing the lock can withdraw the locking pin to remove an article secured to the locking device.
Description
SECURITY DEVICE
The present invention relates to a locking device which is particularly suitable for protecting motorcycles against theft. Typically, a motorcycle is secured using a heavy duty U-type lock or a chain and padlock which is passed through a wheel of the motorcycle. If the U-lock is sufficiently large or the chain is sufficiently long, this may also be passed through a fixed structure such as a railing to prevent the motorcycle being bodily removed.
Whilst these locks are generally reliable, it is recognised that a determined criminal with sufficient time can force these types of locks with relative ease.
According to the present invention, a locking device for fixing to a surface comprises:
a base plate having two upstanding flange members spaced apart and facing one another, each flange member being provided with an aperture which is aligned with a corresponding aperture of the facing flange member; and,
a locking pin adapted to pass through the apertures of the flange members, an end of the locking pin being adapted to co-operate with a locking means to secure the locking pin in position between the two flange members so that the locking pin cannot be withdrawn,
wherein one flange member includes a lock cover which receives the end of the locking pin, the lock cover having an opening which faces the base plate and which provides access to the end of the locking pin when it is in position to enable the locking means to be secured or released.
In the present invention, a locking device which is to be fixed to a surface is provided with a lock cover so that a lock which holds a locking pin in position is only accessible through one opening. As this opening faces a fixed base plate there is insufficient space to insert a tool to force the lock and thereby enable the locking pin to be withdrawn. Only a person who possess the correct means for releasing the lock can withdraw the locking pin to remove an article secured to the locking device.
Preferably, the opening in the lock cover is at a distance of 75mm to 100mm from the base plate. This provides sufficient space to allow hand access.
Preferably, the end of the locking pin is provided with an aperture which extends generally transverse to the longitudinal axis of the locking pin which, in use, receives a plunger lock or the shank of a padlock.
Preferably, the base plate is provided with a number of apertures for receiving anchor fixings which, in use, secure the base plate to the surface. Suitable anchor fixings include expansion anchor bolts.
Preferably, the locking device further comprises means to cover exposed heads of the anchor fixings to deny access to the anchor fixings and thereby prevent the locking device from being bodily removed. Most preferably, the locking device includes a cover plate having two upstanding flange members spaced apart and facing one another, each flange member being provided with an aperture which is aligned with the aperture of the facing flange member, and a number of anchor covers, wherein the cover plate is adapted to fit over the base plate so that the locking pin can pass through the apertures in the flange members of both the base plate and the cover plate to secure the cover plate to the base plate with the anchor covers overlying the anchor fixings.
Preferably, the locking device includes a separate protective sleeve member for the locking pin. In use, the protective sleeve member surrounds a length of the locking pin when it is in position between the flange members and is free to rotate about the longitudinal axis of the locking pin. Preferably, the external surface of the protective sleeve member is formed from a plastics material. The protective sleeve member makes it difficult to saw through the locking pin as the sleeve member must be gripped to prevent rotation and this is made difficult as, when in use, there is generally insufficient room to hold the protective sleeve member.
Preferably, the locking device is manufactured from steel.
The locking device may be secured to any fixed surface that will receive an anchor fixing. Typically, the locking device will be anchored in a floor or a wall either inside or outside a building or on a vehicle.
The surface mountable locking device of the present invention provides a secure means of locking valuable articles such as bicycles, motorcycles and machine tools to protect them from theft. The features of the present invention make the locking device particularly resistant even to the most determined attempts to break the lock or remove the locking device altogether.
An example of the present invention will now be described with reference to the accompanying drawings, in which:
Figure 1 is a front view of an example of a locking device in accordance with the present invention;
Figure 2 is a partial cross-section of the locking device of Figure 1;
Figure 3 is a plan view of the locking device of
Figure 1.
In Figures 1 to 3, a surface mountable locking device comprises a base plate 1 formed from mild steel plate having two upstanding flange members 2 spaced apart and facing one another, each flange member 2 being provided with an aperture 3 which is aligned with a corresponding aperture of the facing flange member. As shown the length of one flange member is increased in relation to the other to help prevent a motorcycle spindle being withdrawn. A locking pin 4 formed from electrically melted tool steel is provided which is adapted to pass through the apertures 3 of the flange members 2.An end 5 of the locking pin is provided with an aperture 6 which extends generally transverse to the longitudinal axis 7 of the locking pin 4 which, as shown in Figure 2, receives a plunger lock 8 to secure the locking pin 4 in position between the two flange members 2 so that the locking pin 4 cannot be withdrawn.
One flange member 2 includes a lock cover 9 which receives the end 5 the locking pin 4. The lock cover 9 has an opening 10 which faces the base plate 1 and which provides the only access to the end 5 of the locking pin 4 when it is in position to enable the plunger lock 8 to be locked or released. The opening 10 in the lock cover 9 is at a distance of approximately 80 millimetres from the base plate 1. This provides sufficient space to allow hand access without leaving space to insert a tool which could be used to force the plunger lock 8 and thereby enable the locking pin 4 to be withdrawn. Only a person who possesses the key for the plunger lock 8 can release the lock and withdraw the locking pin 4 to remove an article secured to the locking device.
The base plate 1 is also provided with a number of apertures for receiving expansion anchor bolts (not shown) which secure the base plate 1 to a surface.
The locking device includes a cover plate 11 having two upstanding flanges 12 spaced apart and facing one another. Each flange member 12 is provided with an aperture 13 which is aligned with the aperture 3 of the facing flange member 2. The cover plate 11 also includes a number of raised cavities which define anchor covers 14.
In use, the cover plate 11 is fitted over the base plate 1 so that the locking pin 4 can pass through the apertures 3 and 13, respectively, of the base plate 1 and cover plate 11 to secure the cover plate 11 to the base plate 1 with the anchor covers 14 overlying the heads of the anchor bolts. This prevents the locking device from being removed altogether by releasing the anchor bolts.
The locking device also includes a separate protective sleeve member 15 for the locking pin 4. As shown, the protective sleeve member 15 surrounds a length of the locking pin 4 when it is in position between the flange members and is free to rotate about the longitudinal axis 7 of the locking pin 4. The external surface of the protective sleeve member 15 is formed from a plastics material. The protective sleeve member 15 makes it difficult to saw through the locking pin 4 as the sleeve member 16 must be gripped to prevent rotation and this is made difficult as, when in use, there is generally insufficient room to hold the protective sleeve member 15.
The head 16 of the locking pin 4 is provided with a slot (not shown) to allow the locking pin 4 to be rotated so that the aperture 6 in the end 5 of the locking pin 4 can be aligned to receive the plunger lock 8. As shown in
Figure 2, an aperture 17 is provided in the lock cover 9 to aid withdrawal of the locking pin 4.
As a further security measure, an annular protective cover 18 is provided on the flange member 2 so that the head of the locking pin 4 is not exposed.
The locking device may be secured to any fixed surface that will receive an anchor fixing. Typically, the locking device will be anchored in a floor or a wall either inside or outside a building or on a vehicle. The surface mountable locking device provides a secure means of locking valuable articles such as bicycles, motorcycles and machine tools to protect them from theft. The features of the invention make the locking device particularly resistant even to the most determined attempts to break the lock or remove the locking device altogether.
