Abstract

Abstract The upper section (2) of a telescopic steering column (1) has an outer tube (2A) and an inner rotatable shaft (2B) and can slide over a splined lower section (3) (arrow A) and can pivot back and forth (arrow B) about a lateral axis (6). The upper section (2) extends through a slider (13) of a clamp (7) so that pivoting of the upper section (2) makes the slider (13) slide relative to a fixed plate (9) in a direction (arrow C) determined by guide means (16,17). Rotation of a control knob (8) extending through the fixed plate (9) causes a clamping block (15) to trap the slider (13) immovably against the fixed plate (9), preventing said pivoting of the upper section (2). At the same time a portion (30) on the block (15) straightens at least one bent spring (24) which then pushes a pad (20) against the outer tube (2A) of the upper section (2) to trap the outer tube (2A) against a part (23) of the slidable plate (13) to prevent said relative sliding movement of the steering column sections. Suitable adjusting means (25 to 28) are preferably provided to ensure the upper section (2) is clamped against said pivoting and sliding movements simultaneously.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 184 words
Vehicle steering apparatus including a steering column comprising a lower part, which is adapted to be mounted in a manner which permits pivotal movement of the steering column about an axis extending laterally of the longitudinal axis of said steering column, an upper part which has a sliding connection with the lower part and includes relatively rotatable members of which one can be clamped in position without affecting the steering action of the column, and means for clamping the said one member, characterised in that the means for clamping comprises a fixture (9) extending substantially laterally of the steering column (1), a slider (13) which is capable of movement along the fixture (9), is connected to the said one member (2A) and carries a pressure pad (20) disposed to bear against the said one member, an operating device (8) which operates a clamp (14,15) to fix the slider (13) relative to the fixture, a spring strip (24) which is located on the slider and provides force for the pressure pad, the spring strip being stressed by engagement with part (15) of the said clamp.
Claim 2
Dependent Claim 184 words
Vehicle steering apparatus including a steering column comprising a lower part, which is adapted to be mounted in a manner which permits pivotal movement of the steering column about an axis extending laterally of the longitudinal axis of said steering column, an upper part which has a sliding connection with the lower part and includes relatively rotatable members of which one can be clamped in position without affecting the steering action of the column, and means for clamping the said one member, characterised in that the means for clamping comprises a fixture (9) extending substantially laterally of the steering column (1), a slider (13) which is capable of movement along the fixture (9), is connected to the said one member (2A) and carries a pressure pad (20) disposed to bear against the said one member, an operating device (8) which operates a clamp (14,15) to fix the slider (13) relative to the fixture, a spring strip (24) which is located on the slider and provides force for the pressure pad, the spring strip being stressed by engagement with part (15) of the said clamp.
Claim 3
Dependent Claim 35 words
Vehicle steering apparatus according to claim 1 in which guide means (16,17) are provided for constraining movement of said slider (13) relative to said fixture (9) to movement back and forth in said one direction.
Claim 4
Dependent Claim 38 words
Vehicle steering apparatus according to claim 1 or claim 2 in which said clamp includes a block (15) which is movable towards said fixture (9) so as to trap the slider (13) between the block and the fixture.
Claim 5
Dependent Claim 37 words
Vehicle steering apparatus according to any of claims 1 to 3, in which the slider has an aperture (18) in which the steering column's upper part (2) is accommodated for longitudinal sliding movement relative to said slider.
Claim 6
Dependent Claim 36 words
Vehicle steering apparatus according to claim 4 in which the pressure pad (20) is loosely mounted in said slider and is arranged to trap the said one member (2A) of the steering column in said aperture.
Claim 7
Dependent Claim 50 words
Vehicle steering apparatus according to any of claims 1 to 5, in which the strip (24) has a bend located intermediate its ends, and in which the bend is engaged by the clamp's part (15) such that the strip is straightened and increases the force exerted by the pad (20).
Claim 8
Dependent Claim 24 words
Vehicle steering apparatus as claimed in claim 6 in which means are provided for adjusting the position of said strip relative to said slider.
