Abstract
Abstract A device for holding at least one of a rotational speed and a rotational angle encoder rigidly attached to a drive shaft includes a holding frame for the encoder, a crossbar spaced from said holding frame for fastening the holding frame to a machine, the holding frame having an upright disposition with substantially vertical side crosspieces, means for attaching substantially vertically disposed leaf springs to the side crosspieces of the holding frame, the leaf springs having respective ends connected to the crossbar, the holding frame having at least another leaf spring fastened to respective ends of the substantially vertical side crosspieces at a substantially horizontal side of the holding frame, and at least one structural element for securing the encoder within a range of section of the other leaf spring.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A device for holding at least one of a rotational speed and a rotational angle encoder rigidly attached to a drive shaft, the holding device comprising a holding frame for the encoder, a crossbar spaced from said holding frame for fastening the holding frame to a machine, said holding frame having an upright disposition with substantially vertical side crosspieces, means for attaching substantially vertically disposed leaf springs to said side crosspieces of said holding frame, said leaf springs having respective ends connected to said crossbar, said holding frame having at least another leaf spring fastened to respective ends of said substantially vertical side crosspieces at a substantially horizontal side of said holding frame, and means for securing the encoder within a range of action of said other leaf spring.
Claim 2
Independent Claim
129 words
A device for holding at least one of a rotational speed and a rotational angle encoder rigidly attached to a drive shaft, the holding device comprising a holding frame for the encoder, a crossbar spaced from said holding frame for fastening the holding frame to a machine, said holding frame having an upright disposition with substantially vertical side crosspieces, means for attaching substantially vertically disposed leaf springs to said side crosspieces of said holding frame, said leaf springs having respective ends connected to said crossbar, said holding frame having at least another leaf spring fastened to respective ends of said substantially vertical side crosspieces at a substantially horizontal side of said holding frame, and means for securing the encoder within a range of action of said other leaf spring.
Claim 3
Dependent Claim
52 words
Holding device according to claim 1, wherein said holding frame comprises said substantially vertical side crosspieces, said other leaf spring as well as a further leaf spring fastened to the respective ends of said substantially vertical side crosspieces located opposite to the ends thereof to which said other leaf spring is fastened.
Claim 4
Dependent Claim
60 words
Holding device according to claim 2, wherein said holding frame comprises said substantially vertical side crosspieces and a pair of mutually spaced substantially horizontal crosspieces rigidly secured at respective ends thereof to said substantially vertical side crosspieces, said other and said further leaf springs being spaced from said substantially horizontal crosspieces at the respective horizontal sides of said holding frame.
Claim 5
Dependent Claim
49 words
Holding device according to claim 3, wherein said encoder securing means include respective pins located at substantially diametrically opposite sides of a housing for the encoder, said pins extending through respective bores formed in said substantially horizontal crosspieces and being fastened to the respective other and further leaf springs.
Claim 6
Dependent Claim
23 words
Holding device according to claim 1 in combination with an encoder held thereby, wherein the encoder is constructed as a hollow-shaft incremental encoder.
