Abstract

Multi-function tool (10) has a hand- grip (12) with a recess (16) on its forward end (14) in which different devices (18, 22, 24, 26, 28) for measurement and testing purposes can be inserted. The device can be used with electrical testing tools if desired.

Description

The The invention relates to a multi-function tool with a handle, on the first end face a holder for different Tools are present.

such Multi-function tools are generally known. These point a handle with holder for various tools, e.g. Screwdriver, wrench, knife blades, saws, telescopic rods or similar Tools.

This Multi-function tools are therefore versatile and save taking various tools for handicrafts. Another benefit is that executives work for this craft activities not a big one Must have a range of tools. These multi-function tools are therefore handy and simple in use.

at craft activities however, there is often a need to carry out measurements and / or tests in order to for example live cables or other items to be able to check or track within a wall or ceiling.

To it is necessary, however, to also include appropriate measuring and / or testing equipment to lead or them at all to get first. This is not only annoying, but also also relatively expensive.

The The invention is therefore based on the object, the possible uses for a To increase multi-function tool of the type mentioned.

This The task is for a multi-function tool of the type mentioned Kind according to the invention Facilities for Measuring and / or testing functions solved.

advantageously, can these devices contain a first single-pole phase tester which has an optical and / or acoustic signal transmitter. This first phase tester is used for testing current carrying Lines through galvanic coupling.

According to one another embodiment but it is also possible current carrying Contactless lines to consider. this is possible by means of a second single-pole phase tester, the optical and / or has acoustic signal generator and the current-carrying lines through a capacitive coupling checks.

It but can also the need pass continuity tests on certain lines in order to to be able to make certain assignments. This is then more advantageous Way possible if the facilities have a continuity tester with optical and / or acoustic signal generator included. The continuity test of a line is carried out by means of an auxiliary electrode.

Further it is sometimes necessary to use magnetic elements such as B. a solenoid valve or a contactor, to check. To can the devices a magnetic sensor with optical and / or acoustic Auto switch included.

It gives handicrafts, where you should know where in a wall or in a ceiling Metal parts such as B. pipes or lines are hidden to not to damage them either or to be able to expose. This is advantageously possible if the devices have one Metal sensor with optical and / or acoustic signal generator included.

Especially It is advantageous if the devices also have a sensor with optical and / or acoustic signal transmitter included to in walls or Cover hidden elements, such as B. wooden beams, plastic pipes etc. to be able to localize.

The largest range of applications offers the multi-function tool according to the invention when it contains all of the above-mentioned measuring and testing equipment.

Some or parts of these devices can be in a cap or in a cover can be added to one of the first end faces of the Handle opposite second face is arranged. these can e.g. an electrically conductive electrode and / or one or the magnetic sensor and be at least one optical signal generator.

A further embodiment the invention provides for all the above-mentioned devices with measurement and / or test functions to provide a common sensor or probe tip that is included in the receptacle is insertable on the first face. Then they are the Equipment associated electrical and electronic components as well as switching and operating devices in or on the handle arranged.

In contrast is but it is also possible for every of the above-mentioned devices a separate plug-in into the receptacle Provide sensor or probe tip.

It is also possible to use the optical and / or train acoustic signaling devices integrated in the handle.

To sees an embodiment the invention before, adjacent to the recording optical signal transmitter to arrange. These optical signal transmitters preferably consist of four light exit points arranged diametrically to each other.

There some facilities require electrical energy, it is advantageous the corresponding energy source inside the hollow cylindrical handle to arrange.

Furthermore the handle can still also the lighting and / or signaling means for the optical and / or acoustic signal transmitter, corresponding controls for the facilities that optical and / or acoustic signal transmitter, sensors of the devices as well as record electronics.

According to the invention created a multi-function tool that is extremely versatile is and at the same time also has easy handling.

Further Features and advantages of the invention will appear from the following Description of an embodiment referring to a single figure showing a top view of represents a multi-function tool.

A multi-function tool 10 consists of an approximately hollow cylindrical handle 12 , on the first face 14 a recording 16 is intended for various mechanical tools. These different tools can e.g. B. Screwdrivers, wrenches, knife blades, saws, telescopic rods and similar tools.

This recording 16 is designed so that it also facilities 18 . 20 . 22 . 26 and 28 for measuring and / or testing functions.

These facilities 18 . 20 . 22 . 26 and 28 can either have a common sensor or probe tip, or can each contain its own sensor or probe tip.

In order to test live lines by galvanic coupling, these devices have a first single-pole phase tester 18 on. This first single-pole phase tester 18 also contains optical and / or acoustic signal generators, which are not shown in the drawing. However, can be on the recording 16 several light exit points can be provided adjacent. Four light exit points are preferably provided diametrically to one another. The necessary illuminants, e.g. B. lamps or LEDs are in the handle 12 integrated.

Of more can the facilities have a second single-pole phase tester optical and / or acoustic signal transmitters included. This second single-pole phase tester serves for contactless Check current carrying Lines through a capacitive coupling.

Another facility consists of a continuity tester 22 with optical and / or acoustic signal transmitters. This continuity tester 22 is used for continuity testing of cables with the help of an auxiliary electrode.

A review of magnetic elements, such as. B. solenoid valves or contactors, is done with the help of a magnetic sensor 24 , which is also provided with optical and / or acoustic signal transmitters.

Both the auxiliary electrode of the continuity tester 22 as well as the magnetic sensor 24 are in a cap or a lid 32 added. This cap or lid 32 is on one of the first faces 14 of the handle 12 opposite second face 30 attached in a suitable manner. The cap or the lid 32 can either with the main body of the handle 12 be screwed, or enter into a snap connection with this main body.

The cap or the lid 32 is therefore designed to be removable, so that a user inside the handle 12 arranged energy source, for example a battery, can be replaced.

There is also a metal sensor 26 with optical and / or acoustic signal transmitters. This metal sensor 26 is used to locate metal parts hidden in walls or ceilings, e.g. B. of pipes or lines.

To also other elements hidden in walls and ceilings, such as. B. wooden beams, plastic pipes, etc. to find and localize is also a sensor 28 with optical and / or acoustic signal transmitters.

The handle 12 itself is hollow and, as already noted above, contains the energy source, the illuminants, operating elements, the optical and / or acoustic signal transmitters, the sensors and the necessary evaluation electronics.

The cross section of the handle 12 is basically round. To assign the functions diametrically to the circumference of the handle 12 , is the round one Cross-section through flat, flat segments 34 interrupted. Each of these flat planar segments 34 carries an operating and signaling element 36 a separate function.
