DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for inhibiting the theft of internal combustion engines, for instance outboard engines, lawn mower engines, chain-saw engines, and like engines of the kind in which one end of a pull-cord is wound firmly around a rotatable magnet on the engine, or motor, and the other end of the cord is attached to a handle, wherein a pull on the cord causes the magnet to rotate and therewith generate an ignition spark in a spark plug or plugs.
Outboard motors are often theft-attractive objects and are often mounted on the boat solely by means of a manually manipulatable attachment. This applies in particular to engines of up to 30 HP. it is a simple matter to detach engines of this kind from the boat to which they are fitted and install the engine on another boat. All that is required is to connect the engine fuel feed to a fuel tank. The theft of such engines can be prevented by bolting the engine securely to the boat, which will normally prevent the theft of the engine itself. However, in cases such as these it is not unusual for theboat to be stolen together with the engine attached. However, the theft of a boat and its engine, or motor, also requires the engine fuel feed to be connected to a fuel tank, in peace and quiet, i.e. while undisturbed. Thefts of this nature may be either planned or spontaneous, with the object of selling the engine/boat.
The inventor and other Applicants have come to the conclusion that there is a need for a device which will at least inhibit unlawful activities in this regard, irrespective of the underlying purpose, and particularly, but not exclusively, the theft of boat engines.
The object of the invention is not only to inhibit the actual theft, but also to cause such damage to a stolen engine as to make it difficult to sell the engine, for instance, should the theft-inhibiting device be successfully overcome. Spontaneous thefts that are carried out for the "sake of fun" can be prevented more effectively, however.
The inventor also realizes that it must be possible to retail a theft-inhibiting device of this kind at a reasonable price, in order for the device to gain popularity with potential customers.
These and other objects are achieved with a device of the kind defined in the introduction and having the characteristic features set forth in the characterizing clause of the following main claim.
The invention will now be described in more detail with reference to an exemplifying embodiment of an inventive theft-inhibiting device and also with reference to the accompanying drawing, in which
FIG. 1 is a longitudinal section view of an inventive device;
FIG. 2 is a front view of the device shown in FIG. 1; and
FIG. 3 illustrates the components of an inventive device.
The theft-inhibiting device is intended for use with internal combustion engines, not shown. More particularly, but not exclusively, the device is intended for use with engines that are started with the aid of a pull-cord whose one end is attached to a rotatable magnet means fitted to the engine. This technique is well known and will not be described or illustrated here.
An outboard engine, or motor, is always provided with an engine casing and an attachment plate 10 may be firmly mounted on one side of the engine casing (not shown). The mounting plate 10 includes a sleeve-like member 11 which is welded firmly to the mounting plate 10 and supported by strengthening means 12'. The mounting plate and the sleeve-like member 11 connected thereto may be firmly mounted on the engine casing in a manner not shown. The end of the sleeve 11 distal from the mounting plate 10 has formed therein a circular groove 12. Alternatively, this end of the sleeve 11 may be collared. In the former case, the opposing vertical walls 13 of the groove 12 each form an abutment or defining surface. Only one forward abutment or defining surface is formed in the latter case.
The reference numeral 14 identifies generally a handgrip which includes a cylindrical body 15 which is received loosely in the sleeve 11. One
