Abstract
Abstract A distance measuring instrument for motor vehicles by which the distance covered is printed by symbols on a card insertable into a slit in the instrument casing, in which there is provided an accummulating counting mechanism which, by a mechanism, can be actuated to move from the non-operative position to an operative position adjacent the slit for stamping the card via ink to mark the accummulated value on the card, and in which the card slit is provided with a curtain which, in the non-operative position, covers an opening through which the stamping mechanism acts during stamping, with the curtain being connected to the stamping mechanism so that it exposes the opening immediately prior to the stamping and returns to the position covering the opening immediately after stamping.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
225 words
A distance measuring instrument for motor vehicles by which the distance covered by the vehicle is printed by symbols, preferably figures, on a card, comprising a casing having a slit into which a card is insertable, an ink containing means adjacent the slit, an accummulating counting mechanism within the casing, means for moving said counting mechanism from a protected nonoperative position remote from the slit to an operating position adjacent the slit for coaction with the ink containing means for stamping the accummulated value on the card inserted in the slit, said means for moving said accumulating counting mechanism comprising a frame, an axle serving simultaneously as a torsion spring about which said frame is rotatably supported, control means for manual actuation of the stamping of the card inserted into the slit, and a locking pawl retaining the frame for the counting mechanism in protected non-operative position until the control means is actuated to release the locking pawl, characterized in that said slit is provided with an opening through which the counting mechanism coacts with the ink containing means during stamping, a curtain covering the opening in the non-operative position of the counting mechanism and means connecting the curtain with the counting mechanism so that the curtain exposes the opening immediately prior to stamping and returns to the position covering the opening immediately after stamping.
Claim 2
Dependent Claim
225 words
A distance measuring instrument for motor vehicles by which the distance covered by the vehicle is printed by symbols, preferably figures, on a card, comprising a casing having a slit into which a card is insertable, an ink containing means adjacent the slit, an accummulating counting mechanism within the casing, means for moving said counting mechanism from a protected nonoperative position remote from the slit to an operating position adjacent the slit for coaction with the ink containing means for stamping the accummulated value on the card inserted in the slit, said means for moving said accumulating counting mechanism comprising a frame, an axle serving simultaneously as a torsion spring about which said frame is rotatably supported, control means for manual actuation of the stamping of the card inserted into the slit, and a locking pawl retaining the frame for the counting mechanism in protected non-operative position until the control means is actuated to release the locking pawl, characterized in that said slit is provided with an opening through which the counting mechanism coacts with the ink containing means during stamping, a curtain covering the opening in the non-operative position of the counting mechanism and means connecting the curtain with the counting mechanism so that the curtain exposes the opening immediately prior to stamping and returns to the position covering the opening immediately after stamping.
Claim 3
Dependent Claim
51 words
The distance measuring instrument as defined in claim 1, characterized in that a hinged arm connects the curtain to the counting mechanism frame (8) so as at stamping movement of the latter the opening (30) is exposed and at the return movement of said stamping device covers again said opening (30).
Claim 4
Dependent Claim
67 words
The distance measuring instrument as defined in claim 1, characterized in that the control means for releasing the counting mechanism for stamping against an inserted card is a control push-button (33) for actuating an elbow joint mechanism (11,39), said elbow joint mechanism being provided with a trigger member (37) adapted, upon depression of the push-button (33), to actuate a pawl release member (38) for the counting mechanism.
Claim 5
Dependent Claim
71 words
The distance measuring instrument as defined in claim 3, characterized in that the push-button (33) at its inner end is provided with a pin (34) adapted to slide in a longitudinal groove (35) in one end of a lever joint (32), which in turn is adapted to straighten said elbow joint mechanism, with said groove (35) forming with the longitudinal axis of the said lever joint an angle ( Alpha ).
Claim 6
Dependent Claim
38 words
The distance measuring instrument as defined in claim 3, characterized in that the push-button (33) remains depressed after performed stamping and for a new stamping is to be pulled out to a preparedness position and thereafter be depressed.
Claim 7
Dependent Claim
59 words
The distance measuring instrument as defined in claim 1, characterized in that the control means is a wheel, said wheel (9) coacting with a non-rotary but axially movable nut (10), which at turning of the wheel to its end position actuates a pawl release member (23), which via an axle (24) transfers the release force to the pawl (12).
Claim 8
Dependent Claim
113 words
The distance measuring instrument as defined in claim 6, characterized in that the torsion spring (20), via an elbow joint (11) being straight at this time, is tensioned at the turning of the wheel (9) by the axial movement of the nut (10) until the pawl (12) releases the counting mechanism frame (8) for striking of the counting mechanism against the card, and that, for returning the counting mechanism to its non-operative position, the elbow joint (11) is caused to leave its straight position by action of a bar (22), which is rigidly mounted on the counting mechanism frame (8) and extends with its free end below and past the elbow joint (11).
Claim 9
Dependent Claim
53 words
The distance measuring instrument as defined in claim 7, characterized in that it comprises a pulling helical spring (13) fastened on the counting mechanism frame (8) and, respectively, on the inner wall of the casing (19) and, subsequent to the release of the pawl (12), returning the counting mechanism to its non-operative position.
