Abstract

A gearbox gearlever locking device for use with automatic and non-automatic gearboxes, which when mounted about the gearlever will enable said gearlever to be locked in a neutral position thus preventing further selection of gears. The device is in the form of a boxlike structure and has a locking plate and key operated lock embodied within it, the locking plate being held in a locked state by the key operated lock, said locking plate being the means whereby the gearlever is held in an entrapped position. <IMAGE>

Description

SPECIFICATION Gear lever locking device This invention relates to a method of locking a gearbox gear lever and making the gearbox inoperative.
Any machine or vehicle which uses a gearbox has no protection hitherto from unlawful usage. The use of a device to prevent such unlawful use would therefore be an advantage.
According to the present invention there is provided a specially designed device which when attached about the gear lever of a gearbox of a vehicle or other machine, it will enable the gear lever of the gearbox to be held in a neutral and therefore safe position which will prevent the gear lever being used to select any gear. The device is fastened to the vehicle or other machine and is in the form of a box 1. having an aperture in the top plate large enough not to impede normal working of the gearbox. This aperture is duplicated in the runner plate 5. set a particular distance below the top plate, this distance so formed being the means whereby a locking plate 2, can be inserted and locked in position, trapping the gear lever against any movement.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings submitted with this application in which: Sheet 1.Figure 1 shows in perspective, the device in its entirely less the means of attachment to the vehicle or otherwise.
Sheet 2. Figures 1 to 3 shows three cut away views of the locking device assembled together.
Figure 4 shows a plan and sectional view of the locking plate 2.
Referring to sheet 1, this shows the locking plate 2, in position with all butting faces a good fit on each other with no gaps on any of the three butting faces of the thicker section.
Referring to sheet 2. Figure 1. A cut away sectional view is provided in 1, showing the locking plate 2, sandwiched between the top plate and the runner plate 5, with a slight clearance gap at each side for ease of insertion. The spring retaining clip 4, is shown riveted to the side of the device as a stowage position for the Locking plate 2. when not in use.
Figure 2 is an end view with cut away sections included for clarity and shows the Locking plate 2, in position and the Mortise lock 3 assembled into the cavity provided, with the Mortise Lock locking member in a locked position.
Figure 3 is a plan view of the device with all parts assembled and showing the cut-out section in the Locking Plate 2 which cut-out shall be of a size and shape capable of retaining the gear lever in a neutral position without undue side or end movement.
The device may be assembled as a separate unit onto the floor of the vehicle or other machine, with suitable backing plates under the mounting flanges to prevent the device being removed bodily. The drawing shows square holes in the device mounting flanges and are intended as an example that a special coach bolt type of holding bolt be used to prevent the bolts from being removed from above.
As an alternative the device may be assembled directly onto the gearbox body and thus become part of the gearbox, or the gearbox casing itself may be altered and modified to include the locking device, which would make it an integral part of the gearbox.
An alternative method of fitment to the vehicle or machine or otherwise is that the mounting flanges are turned through ninety degrees and where necessary shaped to suit the contours or other shapes of the bases on which the device is to be mounted. For example, when the device is mounted on the transmission tunnel above the gearbox in the conventional motor vehicle, the mounting flanges may be bent to shape and either bolted or welded in position, again using substantial backing plates as a guard against forceful removal.
The actual size and shape and aesthetics of the device will depend on the application and on the strength of the material used. The drawing shows a metal fabrication but other methods of production could be used. Metal is shown because of its resistance to damage but other materials may be used if they are deemed suitable.
An alternative method of applying a locking plate is to have the slot thickness and plate thickness continuous and the rectangular opening to accept the tongue of the mortise lock would be a hole and not a formed recess. The serrated portion is optional in all cases.
For automatic gearboxes a similar type of device is required.
The type of lock is optional. For instance a barrel type lock can be used having a rotating lever locking action to engage the locking plate.
1. A gearbox gearlever locking device which is mounted about the gearbox gearlever and comprises a substantially rigid and robust unit of a size and shape capable of holding within the boxlike structure a specially designed locking plate so shaped and arranged as to prevent forceful removal of said locking plate from the structure, and to have incorporated in the design a method of entrapping the gearlever in a neutral gear position and of securing said locking plate in the boxlike structure using a key operated lock to achieve this.
2. A gearbox gearlever locking device as claimed in Claim 1 which when applied to an automatic gearbox adds to or replace wholly or in part, the existing guadrant cover and selection lever casing, or suchlike performing a similar duty, the quadrant gear position markings being transferred to the top of the locking device, or a new modified quadrant cover or suchlike provided. If it is deemed necessary the boxlike structure may be altered and left open ended as long as the action of the locking plate is maintained and the unit remains secure and said locking plate cannot be forcibly removed from the device.
3. A gearbox gearlever locking device as claimed in Claims 1 and 2 whereby the locking device
