Abstract
Abstract A steering mechanism for toy building sets, such as toy vehicles, and of the type comprising a rack means and a pinion cooperating with it. In connection with various possible positions of the rack means and likewise with a view to selective positioning of the pinion cooperating with it, the toothed region of the rack means is provided wholly or partly around the longitudinal axis of the rack means, the rack means being integral with a pair of steering rods which are provided with coupling means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A steering mechanism for toy building sets of the type comprising a rack means (6) and a pinion (10) adapted to cooperate with said rack means, characterized in that the tooth region of the rack means comprises a number of substantially arc-shaped teeth (12), each of said teeth comprising a disc extending perpendicular to and at least partly around the axis of the toothed region, said tooth region being integral with steering rods (13) which project from each end and are provided with coupling means (14), and in that the steering mechanism further includes a bushing means (5) with a substantially cylinder-shaped part having an opening therein (11) which is adapted to slidably receive the rack means, and that the pinion (10) is journalled in bracket means (7 and 8) which are secured to the cylinder-shaped part for cooperation with the rack means.
Claim 2
Dependent Claim
143 words
A steering mechanism for toy building sets of the type comprising a rack means (6) and a pinion (10) adapted to cooperate with said rack means, characterized in that the tooth region of the rack means comprises a number of substantially arc-shaped teeth (12), each of said teeth comprising a disc extending perpendicular to and at least partly around the axis of the toothed region, said tooth region being integral with steering rods (13) which project from each end and are provided with coupling means (14), and in that the steering mechanism further includes a bushing means (5) with a substantially cylinder-shaped part having an opening therein (11) which is adapted to slidably receive the rack means, and that the pinion (10) is journalled in bracket means (7 and 8) which are secured to the cylinder-shaped part for cooperation with the rack means.
Claim 3
Dependent Claim
36 words
A steering mechanism according to claim 1, characterized in that each of the steering rods 13 projecting from the ends of the rack means forms an acute angle with the longitudinal axis of the rack means.
Claim 4
Dependent Claim
23 words
A steering mechanism according to claim 1, characterized in that the bushing means (5) is rotatably journalled in a steering gear housing (1).
Claim 5
Dependent Claim
61 words
A steering gear mechanism according to claim 3, characterized in that the bushing means (5) rotatably journalled in a steering gear housing (1) is provided wholly or partly with a corrugation (15) on its outer face disposed between the bracket means (7 and 8), said corrugation being adapted to slidable engagement with a flexible tongue means provided on the steering housing.
Claim 6
Dependent Claim
23 words
A steering mechanism according to claim 1, characterized in that the teeth (12) of the toothed region encompasses the rack means (6) entirely.
