"Folding rule or the like."

The present innovation relates to a folding rule or a similar measuring device.

Folding rules are often not just used to measure length but also used, for example, as an aid in drawing lines. A construction worker or a carpenter is likely to be probably always carry a folding rule, but hardly a ruler or protractor, regardless of the latter Devices would often be in place.

The aim of hiring is to make a folding rule even more universal applicable.

This is achieved according to the innovation in that at least one joint of a folding rule or the like. with at least one locking device for locking the concerned folding rule members in a certain, not extended angular position is provided. The number of degrees can be applied quietly on the folding rule.

The folding rule can also be used as an inferior knife on this table be used. The arrangement of the folding rule members in different levels should only be part of the gate, since one link can serve as a contact leg and the other as a scribing leg.

Further advantages and details of the innovation are given below with reference to the attached drawing described in more detail, which as an embodiment with a part of the latching device according to the innovation shows equipped folding rule link in plan view.

The limbs 1 of a folding rule are in a known manner connected at the end by means of Sinrastblechen 2 and pivot axes 4 guided through them centrally. The 'Jäinrastbleche 2 can be attached to the links 1 by means of rivets 3 and are each provided with an elevation or elevation. Countersink 5 equipped, which enables adjacent links to snap into place in the extended angular position, i.e. at 0 ° and at 180 °, allowed,

According to the innovation, the metal sheets 2 are provided with a further one, likewise formed from elevations and depressions 6 Unrast device provided. In the one on the drawing The illustrated embodiment are the elevations or depressions 6 outside the elevation or depression 5 arranged, while the corresponding depressions or elevations 6 in the other (not shown) Sheet 2 within the countersink or elevation 5 in

axial direction are provided on the longitudinal axis, so that in addition to the known linrast angles of 0 ° and 180 ° further 2 locking angles at 90 ° and 270 ° can be created. It is advisable to arrange recesses in one of the metal sheets in such a way that the elevations 6 in them

0 and 180 rest to ensure that the links are properly positioned

1 to ensure with these angular positions »

Further angular positions can be made in a corresponding manner be provided in the joint described above and / or in other joints, the recesses or Elevations 6 need to be arranged in only one sheet 2 in a manner other than that described above.

According to a further exemplary embodiment, not shown, the pivot axis 4 forms the central axis of a Star-shaped elevation or depression in the metal sheets 2. The elevations and depressions 5 are superfluous, however, may be present.

According to a likewise advantageous exemplary embodiment, not shown, there are elevations and depressions similar to the embodiments described on page 2, paragraphs 3 and 4 and page 3 »paragraphs 1 and 2 provided, although the elevations and recesses 5 are missing, i.e. a flat surface instead is present, on which further elevations and depressions of any kind can be provided.

The gear numbers of the Sinrastvorrichtungen. according to the innovation 'can be attached in a suitable manner on the folding rule in the area of the joints concerned.

The exemplary embodiments described above can be applied to any desired within the scope of the inventive concept Modify, combine or add to.

Claims (7)

P.A.633 362W.11.67 Protection claims 1. Folding rule or the like, which consists of a number of foldable, in the unfolded state there is a line forming members, for example in a Angular position of 0 ° and ΐ8θ ° in relation to the or engage the adjacent links in the articulation area, characterized in that at least one joint of the Folding rule or the like. with at least one latching device (β) for latching the relevant links (1) in at least a non-stretched 'angular position is provided. 2. Folding rule or the like according to claim 1, characterized in that that the latching device (6) is part of the known latching device intended for extended IJinkellagen (2 - 5) represents. 3. Folding rule according to one of claims 1 and 2, characterized in that the latching device (6) from in the intended locking angle position of the relevant Links (1) matrix-ad patrix-like interlocking Elevations and depressions (6) is formed in the associated Sinrastbleche (2). 4. Folding rule or the like according to claim 3, characterized in that that the locking plates (2) around the common pivot axis (4) with a symmetrical to this arranged, star-shaped recess or elevation are provided. 5. Folding rule or the like, according to claims 1 - 4 » characterized in that at least two, preferably all joints of the folding rule with linrast— devices (6) are equipped for different angular positions of the respective links (1), 6. Zollstook or the like, according to claims 1-5 »thereby characterized that the number of degrees of the 3Üinrastvorrichtungen (6) in the area of the relevant Links (1) are attached to the folding rule. 7. Folding rule or the like. according to one of claims 1-6, characterized in that the punctures of the known locking device by corresponding additional Elevations and depressions in whole or in part due to the linrast device according to the invention are taken over.
