Abstract

Abstract A measuring apparatus for determining a circumferential length of a body comprises an elongate, non-extensible tape measure having a first and a second terminal. A measuring scale is applied to the tape measure. A first and a second sliding part are provided for axially guiding the tape measure. Both sliding parts are provided with an actuating unit allowing to either axially lock the tape measure or to make it axially displaceable in the sliding part. Further, both sliding parts are provided with index marks to allow reading a measuring value with respect to the measuring scale. An elastic band is arranged between the two sliding parts. The tape measure is fixedly attached with one of its terminals to one of the sliding parts. The tape measure then extends around the circumference of a body to be measured, then through the other sliding part and, then, again through the first sliding part. The loop thus formed may be extended by stretching the elastic band. By consecutively locking and unlocking the tape in stretched and non-stretched conditions of the elastic band, a measurement of the circumferential length may be made with a predetermined axial tension in the tape measure to avoid reading errors generated by varying tape tension when measurements are made on elastic bodies.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 205 words
A measuring apparatus for determining a circumferential length of a body, comprising: an elongate, non-extensible tape measure having a first and a second terminal; a measuring scale applied to said tape measure; first guide means for guiding said tape measure, and having first actuating means for either axially locking or allowing axial displacement of said tape measure relative to said first guide means, and, further, having a first index mark adjacent said tape measure; second guide means for guiding said tape measure, and having second actuating means for either axially locking or allowing axial displacement of said tape measure relative to said second guide means, and, further, having a second index mark adjacent said tape means; an elastic element having a first terminal fixedly attached to said first guide means and having a second terminal fixedly attached to said second guide means; said first terminal of said tape measure being fixedly attached to said first guide means in a direction opposite said elastic element, said tape measure extending from said first guide means through said second guide means for being guided therein adjacent said second index mark and, then, extending further through said first guide means for being guided therein adjacent said first index mark.
Claim 2
Dependent Claim 205 words
A measuring apparatus for determining a circumferential length of a body, comprising: an elongate, non-extensible tape measure having a first and a second terminal; a measuring scale applied to said tape measure; first guide means for guiding said tape measure, and having first actuating means for either axially locking or allowing axial displacement of said tape measure relative to said first guide means, and, further, having a first index mark adjacent said tape measure; second guide means for guiding said tape measure, and having second actuating means for either axially locking or allowing axial displacement of said tape measure relative to said second guide means, and, further, having a second index mark adjacent said tape means; an elastic element having a first terminal fixedly attached to said first guide means and having a second terminal fixedly attached to said second guide means; said first terminal of said tape measure being fixedly attached to said first guide means in a direction opposite said elastic element, said tape measure extending from said first guide means through said second guide means for being guided therein adjacent said second index mark and, then, extending further through said first guide means for being guided therein adjacent said first index mark.
Claim 3
Dependent Claim 15 words
The apparatus of claim 1, in which said elastic element is an elastic rubber band.
Claim 4
Dependent Claim 39 words
The apparatus of claim 1, in which a cantilever nonextensible strip with a first terminal is attached to said first guide means, an opposite terminal of said strip carrying a third index mark, cooperating with said second index mark.
Claim 5
Dependent Claim 23 words
The apparatus of claim 1, in which said guide means are made as sliding parts having through-slots for axially guiding said tape measure.
