All of them can be easily exchanged with other bits if required.

Description

The The invention relates to a multi-function key with four cross arms, to the ends of the cross arms arranged tool heads and one of the cross arms connecting central body.

To open and close of windows, doors, Cabinets, Dumpsters, Bollards and similar Components and devices and to press of valves and the like are the most diverse key shapes common. these can three-, four- or six-edged profile or device-specific special shapes exhibit. Caretaker, house craftsmen, builders, etc., but also Police and fire department need therefore usually carry a variety of individual locking tools with it. Furthermore Often there is a need for installation or repair of locks or closing devices special measuring and testing equipment to have on hand. Finally on site also simple hand tools such as screwdrivers etc. needed.

It is already known to provide the user tools with multiple function, which consists of four arms one to one. Cross molded key, wherein the ends of the cross arms each carry a tool head. It is also known to provide at least one of the tool heads as a receiving part for an adapter into which in turn different tools can be inserted with a male or in the whole, see for example the DE 246 17 973 U1 ,

The known multifunction key However, they still have the disadvantage that they are not universal enough are, so for Measurement functions or other special functions more tools needed become.

Of the Invention is based on the object of specifying a multifunction key, the execution common Working on usual closing devices allowed.

According to the invention Task solved by the features of claim 1. Advantageous embodiments are the subject the dependent claims.

• – sind ein erster Werkzeugkopf als Innenvierkant und
• – ein zweiter Werkzeugkopf als Innendreikant ausgebildet,
• – von denen mindestens einer als Aufnahme für ein Einsteckwerkzeug oder einen Werkzeugadapter geeignet ist,
• – ist ein dritter Werkzeugkopf als mit einem Schließbart ausgerüstetes Schließwerkzeug ausgebildet, das an einer Stirnseite eine abgesenkte Bohrung sowie einen Innensechskant zur Aufnahme von Bits unterschiedlichster Ausführung aufweist,
• – weist der das Schließwerkzeug tragende Kreuzarm eine Maßeinteilung zur Ermittlung von Schließzylinderlängen auf,
• – ist ein vierter Werkzeugkopf aus sich stufig zu seinem Ende hin verjüngenden Vierkantabschnitten gebildet und
• – der Zentralkörper mit einem Vierkantdurchbruch versehen.

After that

• Are a first tool head as a square socket and
• A second tool head is designed as an internal striking device,
• - at least one of which is suitable as a receptacle for a plug-in tool or a tool adapter,
• A third tool head is designed as a closing tool equipped with a locking bit, which has a countersunk bore and a hexagon socket for receiving bits of various designs on one end face,
• The crossarm carrying the closing tool has a graduation for determining lock cylinder lengths,
• - Is a fourth tool head formed in stages to its end tapered square sections and
• - Provided the central body with a square opening.

As show the following embodiment is allowed, the inventive multi-function key both the locking and unlocking of Closing means the opening from doors to emergency opening, the locking and unlocking of valves, the testing of square openings, the bleed of radiators and the mounting and dismounting of locking devices and others Functions.

Of the Multifunction key thus provides a universal tool in the hands of janitors, Home builders, facility managers, electricians, disposal companies, glass and building cleaners, chimney sweeps, Masons, painters, plumbing and heating fitters, Police and Fire Department, Security Services locksmiths and home improvement.

The in the figure illustrated embodiment shows an exploded view of a multifunction key according to the invention.

The multifunction key consists of four cross arms 1 to 4 passing through a central central body 5 are connected. At the ends of the cross arms 1 to 4 there is one tool head each 6 to 9 ,

The tool head 6 is designed as a square in several gradations. The individual square sections are used to lock and unlock closures on windows, doors and other equipment, for example, to open doors without door handle (latch). Compared to conventional square tools that taper conically to the front to be used for different hole dimensions, the stepped shape has the advantage that at the Innenvierkantloch the locking device is not only a linear, but a flat support and so greater forces can be transmitted or a notching of the tool is avoided.

At the same time, the square sections have a measuring function. For this purpose they are ent speaking metrics, appropriate as in this embodiment in millimeters, labeled. The label can be designed as a sprue. In this way, it is easy to find out, for example, the matching window handles and mortise locks if the windows and doors are to be completed.

The cross arm 2 carries a tool head 7 which is provided with a square hole. This square socket forms a tool for operating valves or for opening or closing other components or devices that are equipped with a square locking device such as windows, doors, control cabinets or the like. The label on a label area 10 again shows a measure of the square. At the same time this tool head is used 7 also for receiving other, suitable for insertion tools, such as the insertion tools shown 11 to 14 , each with a Vierkanteinsteckzapfen 15 (7 mm) are provided.

The plug-in tool 12 is, for example, a square socket with a different internal dimension than that of the tool head 7 , The plug-in tools 11 and 13 are closing tools with a special profile for actuating switch cabinet closures. The plug-in tool 14 For example, it can be a hexagon socket. Many other variants are conceivable. Thus, further tools may be provided for insertion, which have the form of tubular sockets, triangular socket wrenches, bit receivers and the like.

In just such a way could also the tool head 8th be provided for receiving plug-in tools. These would then have to be provided with a three-edge pin.

The tool head 9 has different functions. First, the tool head offers 9 with his locker 16 the possibility of closing a lock with profile cylinder punching (PZ perforation).

In a purpose of emergency opening with an opening tool half removed lock cylinder, he also serves to open a door lock. He is at the front with a blind hole 17 provided so that the remaining edge can embrace the left middle part of the lock cylinder. The cambar 16 can then engage in the lock and allows by rotation the closing process.

Another function of the tool head 9 is the measurement of the required cylinder length for the equipment of doors of any kind. The cross arm 4 is this with a measuring scale 18 Mistake. Is the tool head 9 placed in a lock position in a mortise lock, can interface with the surface of a door fitting on the measuring scale 18 the correct length for a lock cylinder to be mounted can be read.

Finally, the tool head fulfills 9 another function. In a hexagon blind hole 19 usual bits for screwing in and out of screws can be included.

At the central body 5 is also a tool or adapter mount on a square socket 20 possible. Even as such, the inner square 20 be used as a tool, for example for operating vent valves on radiators.

The cross arms 1 to 4 can be attached to their surfaces with labeling surfaces 21 be provided on which manufacturer's information, company logo or other advertising information can accommodate, for example, when the multifunction key is sold as a giveaway.

Of the Multifunction key will be useful Zinc diecast or other suitable material. He can be much cheaper are offered as the corresponding variety of single keys that for the same functions necessary would, and is universally expandable. The combination shown in the figure of the multifunction key with four or possibly more insertion tools can be in a plastic folding box with molded recesses in appealing Offer form.
