Abstract
Steering wheel device, e.g. for a boat, comprising a steering wheel hub (5) which is rotatably mounted on a steering wheel shaft (9) and is lockable onto the steering wheel shaft by means of a plug inserted into a bore (21) in the steering wheel hub and axially fixed therein, said first plug (23) engaging in a cavity (22) in an element (6) non-rotatably joined to the steering wheel shaft. Said plug can be removed and replaced with a lockable blind plug (24) which is shorter than the first plug and does not engage in the element joined to the steering wheel shaft. This means that the steering wheel is disengaged and there is no steering function with the steering wheel.
Description
Steering device for vehicles and boats
The present invention relates to a steering device for operating steering means on vehicles, e.g. steerable wheels on a land vehicle or a rudder on a boat, comprising a manual steering implement, a hub joined to said steering implement, a steering shaft rotatable by means of the hub and a locking device which has a locking position in which turning of the steering shaft by means of the steering implement is prevented.
Most vehicles have for some time now had a steering wheel lock integrated in the ignition of the vehicle. This steering wheel lock is commonly a locking plunger which is diplaceably mounted in a housing which is securely joined to the steering post to which the steering shaft is rotatably mounted. In the locking position the locking plunger is spring-biased towards the steering shaft which is provided with a cavity into which the plunger snaps after a certain amount of turning of the wheel, whereafter the steering shaft and thus the steering wheel are blocked against additional rotation.
Many steering locks of this type are not too difficult to break through. Some steering locks break and become unlocked if sufficient torque is applied to the steering wheel without thereby breaking other vital components for the steering function. Other steering wheel locks can be broken through by breaking of the locking plunger housing from the steering column.
Other types of theft protection directed to preventing steering of a vehicle are known. One such protection uses a bar lockable to the steering wheel which limits the possibility of turning the wheel, another uses a steering wheel with a quick coupling between the steering wheel and the steering shaft, so that the driver can take the steering wheel with him when he leaves the vehicle. This type of theft protection is used primarily for boats which are left at berth for long periods of time.
The purpose of the present invention is to achieve a steering device of the type described by way of introduction which has a locking device which cannot be forced by applying a large amount of torque to the steering implement, e.g. a steering wheel, so that the lock is broken.
This is achieved according to the invention by virtue of the fact that the steering device comprises first and second lock plungers which are alternatively insertable in a radial bore in the hub, said bore in a position of the hub relative to the steering shaft opening directly facing a radial cavity in the steering shaft or in an element non-rotatably joined to the steering shaft, the first plunger being lockable in the bore in a position in which its inner end projects into the cavity to lock the hub to the steering shaft, and the second lock plunger being lockable in the bore in a position in which its inner end is located radially outside the cavity, so that the steering wheel hub is disengaged from the steering shaft.
With the hub freed from the steering shaft the steering mechanism cannot be used nor can it be restored by mechanical force on the lock. The steering device according to the invention is primarily, but not exclusively, intended for boats which are usually used during weekends and on vacation but are otherwise left at berth during the intervening periods and constitute an advantageous alternative to a steering wheel with a quick coupling, since the first locking plunger is simpler and is much less bulky to take with than an entire steering wheel when the boat is left.
The invention will be described in more detail with reference to examples shown in the accompanying drawings, where
Fig. 1 shows an exploded view of one embodiment of the steering device according to the invention,
Fig. 2 shows a cross section through a portion of the steering device in Fig. 1 with the steering wheel hub released from the steering shaft and
Fig. 3 shows a cross section through a portion of the steering device in Fig. 1 with the steering wheel hub non-rotatably joined to the steering shaft.
In fig. 1, 1 generally designates a manual steering implement in the form of a steering wheel, e.g. a boat steering wheel, comprising a steering wheel rim 2 which is joined via spokes 3 to a center portion 4, which is screwed securely to a steering wheel hub 5. A cylindrical element 6 is surrounded by the hub 5 and is non-rotatably joined to the steering shaft via an axial groove 7 and a key 8 on a steering shaft 9. The element 6 is axially fixed to the steering shaft 9 by means of a screw 10 which is screwed into a threaded bore in the end of the shaft. The screw 10 is screwed through the opening 5b of the hub 5 and after mounting is covered by a disc 12 which is pressed into a groove in the opening 5b so that the upper surface of the disc 12 is in the same plane as the upper surface of the hub and is very difficult to remove.
The hub 5 has a lower flange portion 13 which when mounted abuts against the washers 6a on the underside of the element 6. This means that the element 6 via the screw 10 also fixes the hub 5 axially relative to the steering shaft 9. The washer 6a rests against a bushing 6b surrounding the steering shaft 9. The bushing 6b prevents one from using a Polygrip plier to go past the steering lock and steering via the steering shaft 9. A bottom plate 5a holds a washer 13a against the underside of the flange 13.
The hub is preferably cast in metal. A sleeve 20 with a cylindrical bore 21 is cast in one piece with the hub 5. The bore 21 has a first longer portion 21a and a second shorter portion 21b with smaller diameter than the first portion 21a. The second bore portion 21b opens in the position shown in Figs. 2 and 3 of the hub 5 and the element 6, directly in front of a bore 22 in the element 6. The bore 22 has the same diameter as the bore portion 21b. The outside of the entire hub 5 including the sleeve 20 can be surface tempered to prevent sawing and drilling.
Fig. 1 shows two plungers or plugs 23 and 24, respectively, which are alternatively insertable in the bore 21. The first plunger 23 has a first portion 23 a of the same outer diameter as the inner diameter of the bore portion 21a and a second portion 23b with the same outer diameter as the inner diameter of the bore portion 21b and as the bore 22 in the element 6. With the plunger 23 inserted into the bore 21 and fixed with a threaded cover 20b as shown in Fig. 3, the hub 5 is non-rotatably joined to the shaft 9 to permit normal steering of the vehicle with the steering wheel 1.
The other plunger 24 is actually a cylinder lock and forms a blind plug which is intended to plug the bore 21 when the first plunger 23 has been removed so that no other object can be used to connect the hub 5 to the shaft. The cylinder lock 24 differs from the first plunger 23 firstly by virtue of the fact that it is shorter and lacks the exact correspondence to the portion 23b of the first plunger and secondly by virtue of the fact that it is a mobile key lock with a lock pin 25 which, with the aid of a key 26, can be inserted into a radial groove 27 in the bore 21 to lock the plunger 24 in the bore. By virtue of the groove, the key lock 25 will rotate without resistance when it is subjected to force.
The length of the lock 24 is adapted to the length of the bore 21 so that in the completely inserted position there is no part extending outside the bore. There is thus no protruding part which could be gripped by a tool in an attempt to force the lock. By virtue of the fact that the lock 24 has a constant diameter over its entire length and thus lacks an inner portion corresponding to the portion 23b of the first plunger 23, it cannot be pressed into the bore 22 in the element 6 with the aid of a mandrel and a hammer.
The invention provides a simple and effective theft protection which eliminates many of the disadvantages of hitherto known steering wheel lock devices.
