Arrangement for measuring of lengths

Claim 2

An arrangement for measuring of lengths comprising: a measuring system including a measuring rod and a sensing device, said measuring system being enclosed for protection against disturbing outer influences, a covering shaft receiving said sensing device, resilient sealing lips of bendable material projecting from said covering shaft over its entire length and covering as a roof member said covering shaft, and a driver projecting through said sealing lips and having a cross section of a sword favoring the adherence of said sealing lips.

Claim 3

The arrangement, as set forth in claim 1, wherein said sealing lips are made of synthetic material.

Claim 4

The arrangement, as set forth in claim 2, wherein said sealing lips are made of polyurethane.

Claim 5

The arrangement, as set forth in claim 1, wherein said sealing lips are made of rubber.

Claim 6

The arrangement, as set forth in claim 1, wherein said roof member comprises two pairs of superposed sealing lips, and said driver projects through both said pairs of sealing lips.

Claim 7

The arrangement, as set forth in claim 5, wherein said two pairs of said sealing lips define a chamber therebetween receiving pressurized air.

Claim 8

The arrangement, as set forth in claim 5, wherein one of said pairs of said sealing lips is made of metallic material.

Claim 9

The arrangement, as set forth in claim 7, wherein one of said pairs of sealing lips is made of resilient steel bands.

Claim 10

The arrangement, as set forth in claim 8, wherein said resilient bands are bent rooflike, and the face of said steel bands opposite said driver have a layer of synthetic material. l0. The arrangement, as set forth in claim 9, wherein said layer of synthetic material comprises teflon. ll. The arrangement, as set forth in claim 1, wherein said measuring rod is simultaneously a guide and supporting member for said sensing device, guide elements provided for said sensing device and clamped about said measuring rod, and said measuring rod is supported on its side remote from said sensing device by supporting legs on said covering shaft. l2. The arrangement, as set forth in claim 11, wherein said measuring rod has a plurality of supporting legs, and said guide elements surround said measuring rod to an extent that the passing of said supporting legs therethrough is made possible. l3. The arrangement, as set forth in claim 11, wherein said measuring rod has a prismatic cross section. l4. The arrangement, as set forth in claim 11, wherein said measuring rod has a rectangular cross section. l5. The arrangement, as set forth in claim 11, wherein said measuring rod has a trapezoid cross section.

Claim 11

The arrangement, as set forth in claim 11, wherein said supporting legs project sealingly through said covering shaft.

Claim 12

The arrangement, as set forth in claim 11, which includes a slide supporting said sensing device and including said guide elements, the latter constituting ball bearings.

Claim 13

The arrangEment, as set forth in claim 11, wherein said covering shaft has an opening covered by said rooflike disposed sealing lips.

Claim 14

The arrangement, as set forth in claim 11, wherein said covering shaft is slightly displaceable relative to said measuring rod, and intermediate elastic elements inserted between said measuring system and its covering shaft.

Claim 15

The arrangement, as set forth in claim 19, wherein said supporting legs project sealingly through said covering shaft by means of said elastic elements.

Claim 16

The arrangement, as set forth in claim 1, wherein said covering shaft is made of bendable material.

Claim 17

The arrangement, as set forth in claim 1, wherein said covering shaft and said sealing lips are formed integrally of bendable material.
