DE2350013A1 - Long length and arc marking out device - secures measurement tape with spring clamp giving reading on grip face side - Google Patents

Abstract

Device for the accurate marking out of long lengths and arcs which can be used with all types of measurement tapes. When the tape is positioned in the slot of the device, small hand manoeuvres cause a pair of compasses to become operative. Through a grip clamping device comprising a screw with springs and the compass point, the tape is firmly secured. By means of simple pressure on a knob, the tape is released, and after slackening, it is further automatically secured. Every required dimension from zero upwards can be continually adjustable accurately to within a millimetre, and can be read on the face side of the grip.

Description

. PATENT APPLICATION

Mr. Werner Collet, 655I Hackenheim, Bergstr. 9

■. ■ V

1,) designation; Device for the precise marking of large

sen lengths and arcs. (Tape measure compass)

2.) The following are involved as inventors in the creation of the invention: -

Mr. Werner Collet (mechanical engineer) Head of the refa department in the Heba prefabricated house construction company GmbH & Co. KG residing in 6551 Hackenheim, Bergstr. 9

German nationality. (Sole inventor).

3) The object of the invention:

For the creation of a house or a building in general is an exact measurement of the formwork for concreting the basement floor slab, as well as the creation of the Masonry is indispensable.

This results after measuring the four sides of the shell often difficulties due to a lack of angularity by measuring and / or comparing the two diagonals, are often determined too late and, in some cases, too much- lead borrowed rework. '

Using the "Pythagorean Theorem" and the resulting geometrical triangular construction, can be the exact measurement both in dimensional accuracy as well as angularity on the construction site, for example on a small scale, on the drawing board.

4.) Inventive solution:

The innovation is based on the object to provide a device for marking of large lengths and arcs which do not have the mentioned disadvantages and by the -bedingt by the simplified method A time saving and thus cost reduction is also achieved.

The object is achieved according to the invention in that with Using a device (Fig. 1) each tape measure both can be used as a compass in any design as well as in any length. "

In a further embodiment it is provided that the length dimension or the radius is continuously adjustable in the range from zero to theoretically infinite with a dimensional accuracy of one millimeter "

S09826 / D3S1 ~ * ~

In addition, a clamping device is provided that clamps the tape measure and can be moved by simply pressing a button free gives.

The design of the device .bids according to work-related Guidelines and recommendations, the optimum. The device is available as an accessory to any Use a tape measure and / or design it yourself as a tape measure.

Show it :

Fig. 1, the device in connection with any Tape measure.

Fig. 2, the application of the device on the construction site, for the precise measurement of the floor plan. ^! '

Fig. 3 »the device in connection with a tape measure which has an eyelet at the end through which the second Compass tip, for example, a round iron or a nail is inserted.

Fig. U, the device in connection with a tape measure which has a stop angle at the end that is used as a second compass tip.

Fig. 5: two devices arranged diametrically.

Fig. 6, the device not as an accessory but directly, designed as a tape measure.

In Fig. 1, the device is shown in its entirety.

It consists of a handle (6) which is preferably made of plastic and which is special for better handiness Shaping, (1) is adapted to one hand. The handle is also on one side in its entire length a slot (^) that can hold any tape measure (5) leads. The compass tip (7), preferably made of metal, is fixed with the help of one or more screws (2) on which spring washers or disc springs sit, attached to the handle.

By more or less pre-tensioning the springs with the screws, (2) tape measures of any thickness can be used will. If you press the push button (3) downwards, the slot (**) in which the springs on the Screw (2), which also serves as a pivot point, absorbs the force and enables the tape measure and to be moved hence the change in the radius.

The exact size can easily be read on the tape measure on the front of the handle. · ·

If you let go of the push button (3), part 7 is pushed upwards by the springs on the screws (2) and the tape measure (5) automatically clamped. The strength can be adjusted by preloading the springs.

For example, if the tape measure (5) has an eyelet (8), a second compass point (9) can be passed through this,

There are several possibilities here, which are shown in FIGS. 3-5.

In the push button (3) or in the handle (6) can also A small spirit level can be used to make it easier to hold the compass point vertically.

In Fig. 2, the use of the device on the construction site is shown. ·

On the base of the excavation (10) with the help of a commercially available tape measure (.5), the device (11) and an additional compass point (12) using the ⁿ Pythagorean theorem "and the resulting geometric triangular construction of the ground plan to be created Building measured and torn down at the same time.

In Fig. 3 is a tape measure (5) »the device (11) and a 2nd compass tip (12), for example a nail or a Round iron inserted through an eyelet in the tape measure, illustrated.

FIG. K shows a tape measure (5), the device (11) and, as a 2, compass tip (13), a stop bracket attached to the tape measure. ..

In Fig. 5 is a tape measure (5) and the device (11) Shown two times in a diametrical arrangement as a complete circle.

In Fig. 6, the device is not designed as an accessory but directly as a tape measure compass (14) by the handle is extended and the tape with its storage, a hand crank and a pulley.

The device according to the innovation is particularly suitable for Measuring and marking out great lengths, arcs and floor plans each Type and ensures their exact squareness. It is used in the entire construction industry.
