Abstract
Abstract A length compensation device for Bowden controls, mechanical flexible remote controls or the like with two components adjustable with respect to each other and interlockable in different positions. The mutually interlocked components are retained in the interlocked position by a movable retaining element. The device may be designed so that it automatically carries out a length compensation once the retaining element has been manually moved and unlocked, or the length compensation is automatically carried out.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
152 words
A device for adjusting the length of cables comprising first and second relatively adjustable components which can be locked at different relative positions, wherein said first component is designed as a bush component in a configuration of an index bolt, said index bolt being provided with an outer toothing, and said second component having a configuration of a collet, said collet being integrally provided with elastically bendable arms having an inner toothing, said inner toothing meshing with said outer toothing in a plurality of locking positions, and wherein a displaceable securing element is provided, said securing element being configured as a securing sleeve, said sleeve being slideably mounted on said collet and manually movable along said collet to-and-fro between a securing position and an unlocking position of said arms of said collet, said securing element locking said first and second components in one of said locking positions when in said securing position.
Claim 2
Independent Claim
152 words
A device for adjusting the length of cables comprising first and second relatively adjustable components which can be locked at different relative positions, wherein said first component is designed as a bush component in a configuration of an index bolt, said index bolt being provided with an outer toothing, and said second component having a configuration of a collet, said collet being integrally provided with elastically bendable arms having an inner toothing, said inner toothing meshing with said outer toothing in a plurality of locking positions, and wherein a displaceable securing element is provided, said securing element being configured as a securing sleeve, said sleeve being slideably mounted on said collet and manually movable along said collet to-and-fro between a securing position and an unlocking position of said arms of said collet, said securing element locking said first and second components in one of said locking positions when in said securing position.
Claim 3
Dependent Claim
16 words
The device defined in claim 1, characterized by a reserve of spring excursion between the components.
Claim 4
Dependent Claim
42 words
The device defined in claim 1, wherein a spring resiliently forces said components apart in an operational mode, the force exerted by said spring being larger than a locking impedance of the components when said securing element is in said unlocking position.
Claim 5
Dependent Claim
20 words
The device defined in claim 1, characterized in that the components are hollow and nest into each other for locking.
Claim 6
Dependent Claim
32 words
The device defined in claim 1, characterized in that said outer toothing of said index bolt and said inner toothing of said collet mesh each other along a plurality of longitudinal segments.
Claim 7
Dependent Claim
40 words
The device defined in claim 1, characterized in that one of said components comprises a plurality of locking elements formed at an end of each of said bendable arms, said locking elements abutting a back side of the securing element.
Claim 8
Dependent Claim
42 words
The device defined in claim 6, characterized in that the locking elements comprise a sloping surface associated with a complementary sloping surface on the securing element and in that the securing element is forced by a locking spring into the securing position.
Claim 9
Dependent Claim
32 words
The device defined in claim 7, characterized in that an undercut defined by the securing element sloping surface and a toothing angle is formed between the locking elements and the second component.
Claim 10
Independent Claim
196 words
A device for adjusting the length of cables comprising first and second relatively adjustable components which can be locked at different relative positions, wherein said first component is designed as a bush component in a configuration of an index bolt, said index bolt being provided with an outer toothing, and said second component having a configuration of a collet, said collet being integrally provided with elastically bendable arms having an inner toothing, said inner toothing meshing with said outer toothing in a plurality of locking positions, wherein a displaceable securing element is provided, said securing element being configured as a securing sleeve, said sleeve being slideably mounted on said collet and manually movable along said collet to-and-fro between a securing position and an unlocking position of said arms of said collet, said securing element locking said first and second components in one of said locking positions when in said securing position; and wherein the securing element is locked into one of the locking positions of the first and second components to retain said first and second components in one of said locking positions and the securing element is retained in said securing position by spring loading.
Claim 11
Independent Claim
196 words
A device for adjusting the length of cables comprising first and second relatively adjustable components which can be locked at different relative positions, wherein said first component is designed as a bush component in a configuration of an index bolt, said index bolt being provided with an outer toothing, and said second component having a configuration of a collet, said collet being integrally provided with elastically bendable arms having an inner toothing, said inner toothing meshing with said outer toothing in a plurality of locking positions, wherein a displaceable securing element is provided, said securing element being configured as a securing sleeve, said sleeve being slideably mounted on said collet and manually movable along said collet to-and-fro between a securing position and an unlocking position of said arms of said collet, said securing element locking said first and second components in one of said locking positions when in said securing position; and wherein the securing element is locked into one of the locking positions of the first and second components to retain said first and second components in one of said locking positions and the securing element is retained in said securing position by spring loading.
Claim 12
Independent Claim
205 words
A device for adjusting the length of cables comprising first and second relatively adjustable components which can be locked at different relative positions, wherein said first component is designed as a bush component in a configuration of an index bolt, said index bolt being provided with an outer toothing, and said second component having a configuration of a collet, said collet being integrally provided with elastically bendable arms having an inner toothing, said inner toothing meshing with said outer toothing in a plurality of locking positions, and wherein a displaceable securing element is provided, said securing element being configured as a securing sleeve, said sleeve being slideably mounted on said collet and manually movable along said collet to-and-fro between a securing position and an unlocking position of said arms of said collet, said securing element locking said first and second components in one of said locking positions when in said securing position; and said device further comprising a third component defining a spring-excursion reserve delineating a degree of movement of said first and second components, said spring-excursion reserve being built up relative to the third component by a spring, wherein the spring building up the spring-excursion reserve forces the securing element into said securing position.
