Description
DEVICE FOR PREVENTING ThE UNAUTHORISED
USE OF TOWING EOUIPMENT The present invention relates to a device for preventing unauthorised use of towing equipment. The term 'towing equipment is to be understood as covering, inter alia, hitches mounted on trailers, caravans and the like, and/or the towing bars mounted on towing vehicles.
The present invention provides a device for preventing unauthorised use of at least one item of towing equipment, the device comprising:
a first locking member including a first portion; a second portion spaced from the first portion; and at least one further portion connecting the first and second portions, the first locking member being adapted to receive at least part of said at least one item of towing equipment between the first and second portions;
a second locking member, co-operable with at least one portion of the first locking member, and which is operable to confine said at least part of said at least one item of towing equipment between the first and second portions; and
locking means operable to lock the first and second locking members together and thereby to lockingly confine said at least part of said at least one item of towing equipment member between the first and second portions.
Preferably, said at least one portion of the first locking member is provided with at least one recess, which in co-operation with the second locking member constitutes at least part of an aperture through which a member of said at least one item of towing equipment passes, and thereby is operable to confine said at least part of said at least one item of towing equipment between the first and second portions. As revealed hereinafter, said at least one item of towing equipment may comprise, depending on the circumstances, a hitch, a towing bar, or a combination of the two when they are attached to one another.
In a first embodiment of the invention, especially adapted for preventing the unauthorised use of a hitch which is not attached to the towing bar of a vehicle, said at least part of said at least one item of towing equipment comprises the hitch socket and said member of said at least one item of towing equipment comprises the hitch handle.
Thus, in this embodiment, the first portion of the first locking member is provided with a first of said at least one recess, which in co-operation with the second locking member constitutes at least part of an aperture through which the hitch handle passes and thereby is operable to confine the hitch socket between the first and second portions. This aperture is hereinafter referred to as the 'handle-receiving' aperture.
It will be appreciated by the skilled man that a device in accordance with the foregoing first embodiment of the invention would be equally suitable for use in preventing the unauthorised use of an unhitched towing bar.
For such an application, the so-called handle-receiving aperture is adapted to receive a part of a towing bar.
In a second embodiment of the invention, especially adapted for preventing the unauthorised use of a hitch attached to a towing bar of a vehicle, a second item of towing equipment is involved, namely, the towing bar which is attached to the hitch. In such an arrangement, the part of the towing bar to be confined between the first and second portions of the first locking member may be the towing ball. In addition to the features described in relation to the first embodiment of the invention, in this embodiment, there is provided a second of said at least one recess which is disposed on the second portion and, which in co-operation with the second locking member constitutes at least part of an aperture through which a member of the towing bar passes, and thereby is operable to confine the towing ball between said first and second portions.
Depending on the particular construction of the hitch, the last mentioned member may be the actual ball-shaped portion of the towing ball, or the neck of the towing ball. This aperture is hereinafter referred to as the 'ball-receiving' aperture.
The second embodiment of the invention may be modified so as to dispense with the handle-receiving aperture in circumstances where the overall size of the device is not of prime consideration. In such a modified embodiment, the device must be large enough between the first and second portions of the first locking member to accommodate the whole hitch handle.
Preferably, the first and second locking members are in the form of an outer body and inner body, respectively, the inner body being slidingly receivable within the outer body.
In the preferred embodiment of the invention, the outer body is provided with two of said at least one recesses, and the inner body is provided with three recesses and may be received within the outer body in two orientations. In the first orientation, a first of said three recesses is in register with the first of said at least one recess and thereby forms the 'handle-receiving' aperture. In the second orientation, a second of said three recesses is in register with the first of said at least one recess, and a third of said three recesses is in register with the second of said at least one recess, whereby the handle-receiving aperture and the ballreceiving aperture are respectively formed.
Thus, it will be appreciated that this preferred embodiment of the invention, the device is operable to both prevent the unauthorised use of a hitch which is not attached to the towing bar of a vehicle (or alternatively the tow bar itself, as previously mentioned), as in the first embodiment of the invention, and also the unauthorised use of a hitch which is attached to the towing bar of a vehicle, as in the second embodiment of the invention, by selecting the orientation of the inner body with respect to the outer body, as appropriate.
For the sake of brevity, the term 'hitch lock' is employed hereinafter to designate any device which prevents unauthorised use a hitch whether it be attached to the towing bar of a vehicle or not.
Exemplary embodiments of a hitch lock in accordance with the present invention are hereinafter described with reference to the accompanying drawings, in which :
Figure 1 shows a perspective view of the outer body of the hitch lock;
Figure 2 shows a perspective view of the inner body of the hitch lock;
Figure 3 shows a plan view of the hitch lock in a first configuration;
Figure 4 shows a plan view of the hitch lock in a second configuration;
Figure 5 shows a side view of the hitch lock of Figure 3, in operation in its 'disabling' mode; and
Figure 6 shows a side view of the hitch lock of Figure 4, in operation in its 'locking' mode.
A hitch lock, generally denoted 1, comprises a first locking member in the form of an outer body 3, and a second locking member in the form of an inner body 13. The outer and inner bodies are complementary, whereby the inner body 13 may be slidingly received within the outer body 3.
Referring to Figure 1 and using Figure 1 as a frame of reference, the outer body 3 is constructed as a hollow rectangular box having a minor end face and an adjacent major side face removed. The outer body 3 includes upper and lower recesses 6,7 on respective upper and lower faces 4,5, the upper recess 6 being generally centrally disposed along the length of the upper face 4 and the lower recess 7 being disposed generally at an end of the outer body 3.
The upper and lower faces 4,5, at a position adjacent the removed minor face end, are provided with retainment flanges 10. The outer body 3 is further provided with a locking aperture 8 (shown in ghost) which receives locking mechanism 20 (not shown).
Referring to Figure 2 and using Figure 2 as a frame of reference, the inner body 13 is also constructed as a rectangular hollow box having both minor end faces and a connecting major side face removed. The inner body 13 is provided with a recess 16 on face 14, and recesses 17,18 on face 15, recesses 16,17 being disposed generally centrally along the length of the inner body 13, and recess 18 being disposed generally at one end of the inner body 13. The inner body 13 is also provided with a pair of upstanding locking flanges 19, the flanges 19 being positioned on opposite faces 14 and 15, and at opposite ends of the inner body 13.
From the foregoing, it will be appreciated by the skilled man that the hitch lock of the present invention has two configurations.
A first configuration is shown in Figure 3. For reasons which will become apparent hereinafter, this configuration is referred to as the 'disabling mode' of operation. In this configuration, the inner body 13 is slidingly received in the outer body 3 such that upper recess 6 of the outer body 3 is in register with recess 17 of the inner body, the recesses thereby forming a closed handle-receiving aperture denoted 21.
In a second configuration, known as the 'locking mode' of operation, the inner body 13 is slidingly received in the outer body 3 such that (i) the upper recess 6 of the outer body 3 is in register with the recess 16 of the inner body, these recesses thereby forming a closed handlereceiving aperture denoted 22 and (ii) the lower recess 7 of the outer body 3 is in register with the recess 18 of the inner body 13, these recesses thereby forming a closed ball-receiving aperture 24.
It will be appreciated that, by the provision of two upstanding locking flanges 19 at opposite ends of the inner body 3 that in either mode of operation one of the flanges will be adjacent the locking mechanism 20.
In operation, in the 'disabling' mode, wherein the hitch lock is required to secure a hitch 50 which is not attached to an associated tow bar 60, the respective bodies 3,13 are oriented relative to each other, in a manner previously described. Referring to Figure 5, the respective bodies are then positioned on opposite sides of a hitch 50 such that the hitch handle 52 is intermediate recesses 6 and 17, whereby on slidingly engaging the bodies 3,15 as previously described, the hitch handle 52 is encapsulated in aperture 19. The hitch 50 may then be lockingly confined between the two bodies 3,13 by activating the locking mechanism 20. Once the locking mechanism 20 is locked, the hitch socket 54 is inaccessible to an unauthorised third party.
In operation, in the 'locking mode' wherein the hitch lock 1 is required to lock a hitch 50 which is attached to an associated tow bar 60, the respective bodies are oriented relative to each other, in a manner previously described. Referring to Figure 6, the respective bodies are then again positioned on opposite sides of hitch 50, which is engaging tow bar 60, such that the hitch handle 52 is intermediate recesses 6 and 16 and the neck 64 of the towing ball 62 is intermediate recesses 7 and 18, whereby on slidingly engaging the bodies 3,13 as previously described, the hitch handle 52 is encapsulated in handlereceiving aperture 22 and the neck 64 of the towing ball 62 is encapsulated in ball-receiving aperture 24. The hitch 50 may then be lockingly confined between the two bodies 3,13 by activating the locking mechanism 20 (not shown).
Thus, it will be appreciated that this preferred embodiment of the invention, the device is operable to both prevent the unauthorised use of a hitch which is not attached to the towing bar of a vehicle, as in the first embodiment of the invention, and prevent the unauthorised use of a hitch which is attached to the towing bar of a vehicle by selecting the orientation of the inner body with respect to the outer body as appropriate.
It will also be appreciated that the device can be used in the disabling mode with respect to the towing bar 60, in which mode the device is attached to the towing ball 62 and thus renders the towing bar inaccessible.
The locking mechanism 20, which has not been depicted in the drawings, is of a known construction, which when in a locked state engages its locking member with the flange 19, and thereby, prevents the sliding separation of the outer and inner bodies 3,13.
