Description

Background of the invention

Field of the invention

The invention relates to an end piece for a tape measure, which helps

To avoid measurement errors

Description of the current state of the art

Tape measures are tools that can be used to determine the length of objects by simply juxtaposing tape measure and object.

Tape measures are often used on construction sites and in the craft trade.

To measure the tape measure is applied to the object to be measured and then the engraved on the top of the tape measure number indicating the distance between the tail and engraving read. Here are two types of measurements to distinguish, namely external measurements, with which, for. the length of a board and internal measurements with those e.g. the length of a slot can be measured.

The tape measure tail usually consists of an angle. In an external measurement, the tape measure is applied so that the object to be measured is applied to the inside of the angle, while in an internal measurement, the outside of the angle is applied to the inside of the object to be measured. Therefore, a measurement uncertainty occurs which corresponds to the thickness of the angle.

In the US 2010/0175273 A1 a tape measure is described with a magnetic tip, wherein the magnets are arranged in a stop surface. The magnets can have a variety of different shapes. The magnets are rigid and firmly connected to the stop surface.

Also the US 2007/0074418 A , the US 2009/0064525 A1 , the US 2009/0288307 A1 and the US 2013/0298417 A1 show Bandmaßendstücke with permanently installed holding magnet.

The US 2014/0007444 A1 shows a tape measure tail containing two separate stop angle, one of which has a magnetic element.

Object of the invention

The invention has for its object to provide a tape measure, in which the measurement uncertainty by using a longitudinally displaceable part does not occur and the tape measure can be kept variable at the element to be measured.

Another object of the invention is to make the construction simple in order to allow a cost-effective production.

Detailed description of the preferred embodiment

• -- eine Bandmaßkopfbasis (1), die auf einer Seite eine Anzahl Verbindungsschlitze (11) zur Verbindung mit einem Bandmaß hat, entlang derer sie zur Einstellung des Anfangspunktes der Messung auf dem Bandmaß verschiebbar ist und auf der anderen einen Anschlagwinkel (12) mit einer ersten Anschlagfläche (121) und einer zweiten Anschlagfläche (122);
• -- einen mit der Bandmaßkopfbasis (1) verbundenen Kopfsitz (2), der auf einer Seite eine Aufnahmenut (21) für die Aufnahme eines Magnetelements (22) hat, das durch mindestens einen Anschlag (23) gegen Herausfallen gesichert ist.

Out 1 to 7 it can be seen that the tape measure tail according to the invention includes:

• a tape measure head base ( 1 ), which have a number of connection slots on one side ( 11 ) for connection to a tape measure along which it is displaceable on the tape measure for setting the starting point of the measurement and on the other a stop angle ( 12 ) with a first stop surface ( 121 ) and a second stop surface ( 122 );
• - one with the tape gauge head base ( 1 ) connected head seat ( 2 ), which on one side a receiving groove ( 21 ) for receiving a magnetic element ( 22 ) by at least one stop ( 23 ) is secured against falling out.

The said tape measure head base ( 1 ) is with the head seat ( 2 ), which for reinforcement a fastening part ( 24 ) with one with one of the mounting slots ( 11 ) aligned mounting hole ( 241 ), connected by riveting or welding.

The magnetic element ( 22 ) is either rotatable in the receiving groove ( 21 ) or firmly anchored in it. When the magnetic element ( 22 ) is rotatably mounted, it is designed as a round pin, which has a gradation in the longitudinal direction or as a cone. The receiving groove ( 21 ) then receives a corresponding form. When permanently installed, the magnetic element ( 22 ) not round, whereby here also the shape of the receiving groove ( 21 ) to the shape of the magnetic element ( 22 ) is adjusted.

In the drawings, in each case a rotatable magnetic element ( 22 ). By applying the test object to the first stop surface ( 121 ) or the second stop surface ( 122 ) on the inside of the stop angle ( 12 ) outside measurements and by applying the outside of the stop angle ( 12 ) on the inside of the test object internal measurements are performed. Because the Tape Measure Head Base ( 1 ) has a certain thickness, thereby creating a small measurement error. By the construction of the connection slots ( 11 ), the influence of the thickness of the tape measuring head base ( 1 ) are minimized. For internal measurements, the magnetic element ( 22 ) magnetically to a magnetic object and so a permanent contact between Bandmaßkopfbasis ( 1 ) and measuring object. From the above explanation it is evident that the construction of the connection slots ( 11 ) is responsible for the ease of handling with high precision of the measurement and also that the head seat ( 2 ) either by riveting or by welding to the tape measuring head base ( 1 ), and that the magnetic element ( 22 ) by a stop ( 23 ) in the receiving groove ( 21 ) and prevented from falling out. This is part of the superiority of the invention and also allows for cost reduction in manufacturing. In addition, the mounting hole ( 241 ) of the fastening part ( 24 ) and the connection slots ( 11 ), whereby the connection between the tape gauge head base ( 1 ) and head seat ( 2 ) is solidified.

8th and 9 show two more different types of tape measure base ( 1a ) and head seat ( 2a ), whereby the deviations are limited to the appearance. The function is the same.

1. 1. Durch Einsatz der Verbindungsschlitze (11) wird die Messgenauigkeit verbessert.
2. 2. Durch Bereitstellen einer ersten und einer zweiten Anschlagfläche (21, 122) wird die Benutzung vereinfacht.
3. 3. Durch Einsatz eines Anschlags (23) zur Sicherung des Magnetelements (22) gegen Herausfallen wird die Konstruktion vereinfacht und damit die Herstellung verbilligt.

The advantages of a tape measure tail according to the invention are as follows:

1. 1. By using the connection slots ( 11 ) the measuring accuracy is improved.
2. 2. By providing a first and a second stop surface ( 21 . 122 ) the use is simplified.
3. 3. By using a stop ( 23 ) for securing the magnetic element ( 22 ) against falling out, the construction is simplified, making the production cheaper.
