PATENT SPECIFICATION
Application No 348/78 ( 22) Filed 5 Jan 1978 Convention Application No 2700581 ( 32) Filed 7 Fed Rep of Germany (DE) Jan 1977 in ( 44) Complete Specification Published 17 Dec 1980 ( 51) INT CL 3 E 05 B 65/22 ( 52) Index at Acceptance E 2 A 100 108 115 404 AR ( 54) STEERING LOCK ( 71) We, NEIMAN S A, a French Body Corporate, of 39 Avenue Marceau, Courbevoie, France do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:The invention relates to a steering lock, more especially for motor cycles, comprising a lock reception housing which is fixedly connected to the vehicle steering assembly and in which a locking bolt, which is insertable into the steering shaft, and a cylinder lock are located in an axially parallel manner so as to be axially displaceable and being fastened to one another, and comprising a locking part which is secured to the cylinder core and projects beyond the cylinder housing and can be inserted into internal recesses in the lock reception housing so as to fix the cylinder lock in the locking positions.
In a known steering lock, the cylinder core comprises, for arresting the longitudinal displacement of the locking bolt, a radial pin which, in the locking position, penetrates into one of two grooves in the lock reception housing and by this means fixes both the cylinder lock and the locking bolt secured to the cylinder lock Upon the forced twisting of the steering shaft, the steering shaft exerts a shearing force on the locking bolt, causing it to be pressed axially into the lock reception housing This axial pressure is transferred from the locking bolt to the cylinder lock and from this latter to the free-standing locking pins The cylinder lock, which as a rule is made of a material that is less solid than the locking bolt and is preferably given small dimensions for cost reasons, is unsuitable for stresses of this kind Furthermore, the locking member fixedly connected to the rotatable cylinder core is subjected to shearing stress in the reception housing recess and has to have a cross section of corresponding size In order to construct this known steering lock in an operationally reliable and rugged manner, it would be necessary to construct the cylinder lock, the locking member and thus the entire steering lock in dimensions which are so large that it could hardly be used for vehicles Over and above this, the production thereof would be more elaborate and expensive.
An object of the invention is to improve a steering lock of the kind mentioned at the beginning in such a way that a higher compressive stress can be absorbed while the dimensions are the same and the construction is simple.
According to the invention we provide a steering lock for vehicles comprising a lock reception housing for attachment to a column of the vehicle steering shaft and in which there are arranged in an axially parallel manner a locking bolt to be introduced into the steering shaft and a cylinder lock so as to be axially displaceable, the bolt and lock being inter-connected, the lock comprising a cylinder housing, a cylinder core within the housing, a locking part which projects beyond the cylinder housing and can be introduced, for fixing the cylinder lock in the locking positions, into an inner recess of the lock reception housing, wherein the locking part is a ring sector which, in the locking position, projects with one portion into the recess of the lock reception housing in an interlocking manner and stays with the remaining portion in a recess of the locking bolt, which latter recess receives the ring sector in the displaced position and comprises a surface which is normal to the locking bolt longitudinal axis.
In the case of the lock according to the invention, the pressure exerted on the locking bolt is not transferred via the cylinder lock to the locking part and the lock ( 21) » ( 31) ( 33) T 1 I ( 11) 1 581 797 1 581 797 reception housing, but the forces exerted on the locking bolt are directly absorbed by the ring-sector-shaped locking part and are passed on to the lock reception housing The locking part forms a position connection between the locking bolt and the lock reception housing and keeps away any stress from the cylinder lock There is no need for the cylinder lock to be more robust in construction than is usual, and the ringsector-shaped locking part is capable of absorbing high forces.
In a further development, the invention proposes that the ring sector should be formed integrally with a ring, which is concentrically fastened on the cylinder core jacket, so that it is concentrically located on the outside thereof Such an integral design of the ring sector with a ring allows a simple fastening to the cylinder core without changing the design of the usual cylinder core.
The ring may be fastened on the cylinder core section which projects from the cylinder housing on the end that is remote from the key.
In order to ensure a reliable transfer of force, the surface of the locking bolt should rest closely against the front end of the ring sector A simple production of the locking bolt is brought about in that the locking bolt surface resting against the ring sector is formed by a recess.
The ring sector will have sufficient strength if its outer edge has a width which corresponds approximately to the width of the face of the portion of the cylinder housing containing the locking pins If the ring segment were to be constructed even wider, then the longitudinal opening of the lock reception housing required for axial displacement would have to be widened, which would cause a weakening of the lock reception housing.
An exemplified embodiment of the invention is shown in the drawings and will be described in more detal hereinafter In the drawings: Figure 1 is a longitudinal section through the steering lock according to the invention; and Figure 2 is a section along I-l in Figure 1.
Two parallel bores of equal diameter are arranged closely side by side in a fixedly installable lock reception housing 3 and are connected by a longitudinal passage 13 The bore receiving a locking bolt 4 extends through the entire lock reception housing and is thus opened towards both ends while the bore receiving a cylinder lock housing 6 is closed towards the longitudinal spindle (not shown) and only comprises an opening in the direction of the opposite end for the insertion of a key 11 On the end that is remote from the longitudinal spindle, the lock reception housing is provided with a covering cap 7 which comprises, for the introduction of the key, an opening which can be covered by a swivelling cover 8.
For the formation of a recess 4 b, there is provided in the locking bolt 4 a groove which is normal to the locking bolt longitudinal axis and in which the part 12 of the cylinder lock housing 6 containing locking pins (not shown) is located in a form-fitting manner and positively inter-connects the bolt and the cylinder lock In the cylinder housing 6, there is rotatably mounted the cylinder core 9 which projects to some extent from the cylinder housing on the end that is remote from the key and carried a ring 2, whose inside radius is identical with the outside radius of the cylinder core 9 and whose outside radius is identical with the outside radius of the cylinder housing 6 The front end of the ring 2 closely abuts the back end of the cylinder housing 6 or is only a short distance therefrom and comprises, for the formation of a locking part, a ring sector 1 which projects radially beyond its circumferential surface and is coaxial with the ring 2 and, in the non-locking position, covers the area of the cylinder housing interconnecting portion 12, which area adjoins the cylindrical portion of the cylinder housing, and thus has the width approximately the same as that of the interconnecting portion 12.
The ring sector 1 may have the same axial extension as the ring and thus rest with its face against the face 12 a of the cylinder housing portion 12 or alternatively may be a short distance from the face 12 a However, the opposite face of the ring sector 1 always rests closely against a surface 4 a of the locking bolt 4, which face is vertical to the locking bolt longitudinal axis and is formed by a recess 4 c of the width of axial extension of the ring 2.
The cylinder core 9 projects, with an end portion, from the ring 2, on which there is fastened a helical compression spring 5 which is supported with one end on the ring 2 and with the opposite end on an inner wall of the lock reception housing The cylinder lock and the locking bolt can be moved against the pressure exerted by this spring 5 by the key pressure from the position in Figure 1 to a second position in the unlocked state, in which position the locking bolt 4 projects from the lock reception housing 3 and the ring sector is no longer at the level of a first groove (not shown) but is at the level of a second groove 10, into which the ring sector 1 can be swung by the rotation of the key to the locking position.
In the locking position, the ring sector 1 is not located fully in one of the grooves 10, as shown in Figure 2, but only an area la thereof is, so that a second area lb of the ring sector stays in the angle a, through 3 1 581 797 3 which the cylinder core is rotated from the unlocked position to the locking position, is only approximately half as large as is the centre angle 3 of the ring segment 1 In the locking position, the surface 4 a of the locking bolt closely abuts the area lb and the side edge 10 a of the groove 10 closely abuts the opposite area lha of the ring segment By this means, the ring segment 1 transmits the forces acting on the locking bolt 4 directly to the lock reception housing 3.
There is no absolute need for the arrangement of the side surfaces Ic of the ring sector or ring portion to be radial, and they may be directed differently The ring sector shown in Figure 2 has, for example, parallel side walls Ic.
