The invention relates to a holder for a board according to the preamble of the patent claim

1.

The invention also relates to a tool for opening and / or closing a holder for a board according to the preamble of patent claim 9.

Holders for boards, in particular license plates, are, for example, from FR 2 746 944 A1 and DE

GB 2 067 328 A is known. However, problems with holding boards are that such holders should not be able to be opened easily by unauthorized persons, and a certain degree of security should be offered or removal or removal of the board from such a holder should be made more difficult. Particularly in the case of holders of license plates to be attached to motor vehicles, statutory regulations or to meet certain minimum requirements regarding the attachment of such markings; For example, a lock on a holder that can be operated with a coin does not comply with the provisions of the Motor Vehicle Act.

From DE 28 53 754 an anti-theft device for motor vehicle license plates is known. In this case, a base for holding the license plate is fixed to the body of the vehicle with a disc having two diametrically opposed recesses. This disc is hidden beneath the board and cannot be accessed from the outside without destroying the number board.

From US 4,280,348A a screw provided with recesses is provided, which is used to secure decorative caps of wheels. From US Pat. No. 4,742,702A a screw element provided with recesses is known which is used to secure wheel nuts.

From AT-001.439U1 a device for attaching a board to a base is known. This device for attaching a license plate to a motor vehicle has a base plate, which has La25 fixedly connected to the base plate at its upper edge, which extends over an inserted license plate. At the bottom, the base plate has a raised edge in which tabs are pivotably mounted. The tabs consist of a plate-shaped base body and a pin protruding from the rear side of the same, which is rotatably arranged in a bore. The circumference of the plate-shaped base body is formed by at least one circular segment and a secant adjoining the circular segment, in such a way that in the various rotational positions of the tab the plate-shaped base body either engages over or exposes the inserted license plate. This device corresponds to a holder of the type mentioned at the beginning.

The object of the invention is to create a simply constructed holder which, while being simple to operate and manufacture, nevertheless offers a required minimum level of security against unauthorized removal of a plate, in particular a license plate.

According to the invention, this object is cited in the characterizing part of claim 1

Characteristics achieved. Due to the design according to the invention, the secured panel can only be removed with a special tool; acceptance without such a tool is considerably more difficult.

A specially constructed tool with which a board secured according to the invention can be removed from the holder is characterized by the features cited in the characterizing part of claim 9.

According to the invention, a certain amount of effort is thus required, which, depending on the complexity of the recesses or depressions formed in the locking element, can be set more or less high in order to remove a panel from the holder. The recesses or depressions in the end face of the locking element can assume a complex shape, so that only tools with specially designed pins enable the locking element to be unlocked. In particular, if the locking element is not easy to move, but rather difficult to move by appropriate inhibiting devices or elements, unlocking can only take place with the tool provided for this purpose.

Preferred embodiments of the invention emerge from the following description, from the patent claims and from the drawing.

1 and 1a schematically show the view of a holder. Figs. 2, 3 and 4 are views of a

Locking element. 5 shows a view of a holder with an alternative embodiment of a locking element which is shown in detail in FIGS. 6, 7, 8 and 8a. Fig. 9,

AT 412 864 B and 11 show views of a tool.

Fig. 1 shows a front view of a holder 1 according to the invention, in which the frame part 5 and support parts 18 of a base 3 or a carrier can be seen. Such a holder 1 is shown in side view in Fig. 1a, in which the base 3, a panel 2 inserted between the base 3 and the frame part 5 and hinges or webs 4 can be seen, which make the base 3 and the frame part 5 elastic or pivot with each other. From Fig. 1a also shows a recess 8 in the base 3, into which a locking element 6 with its locking part 7 can be inserted in order to fix the frame part 5 on the base 3.

In Fig. 3, the formation of the lower part of the frame part 5 and the base 3 with the recess 8 is shown in section. Through the elongated recess 8, which advantageously runs parallel to the lower part of the frame part 5, the locking part 7 can be pushed through and when the locking element 6 is rotated, the locking part 7 engages behind the edges of the recess 8 and locks the frame part 5 with respect to the base 3. The base 3 and / or the frame part 5 overlap the edges of the board 2, and the board 2 arranged between the base 3 and the frame part 5 is thus secured against removal. The locking element 6 is designed in the form of a pin which is rotatably mounted in the edge region of the frame part 5. Recesses 10, as can be seen in FIG. 2, are formed in the end face 9 of the locking element 6. These recesses 10 are used to accommodate a tool

15th (Fig. 11 to 13), with which the locking element 6 can be rotated. By forming a correspondingly high frictional resistance by means of inhibiting elements 22, for example By corrugating the surface 23 of the area 11 of the locking element 6 facing the frame part 5 and forming corresponding grooves in the contact area of ​​this area 11 on the frame part 5 or by forming interacting latching lugs, webs or the like, the locking element 6 can be difficult to move, so that this can only be unlocked with a tool 15 provided for unlocking.

Fig. 4 shows a detailed view of the base 3 from behind. It can be seen that the locking part 7 is in the locking position. At the same time, the recesses 10 of the locking element 6 are aligned with the recess 8, which is formed in the base 3 and through which the locking part 7 is pushed when closing. By aligning the recesses 10 with the recess 8, it is achieved that if too long pins 17 of the tool 15 are inserted into the recesses 10, twisting of the locking element 6 is not possible, since twisting when the pins 17 pass through the recess 8 of the locking element 6 is hindered by the pins 17 protruding into the recess 8. It is therefore for the tool

15th required to have a very specific pin length in order to be able to unlock the locking elements 6 in a simple manner.

9, 10 and 11 show different views of the tool 15 for opening and closing a holder 1 according to the invention. An approximately car key-shaped tool 15 can be seen, from the end face 16 of which three pins 17 extend. These pins 17 have different lengths. The central pin is used to be inserted into the central recess 10 shown in FIGS. The two shorter pins are inserted into the two further recesses 10 located next to the central recess 10. Due to the precisely dimensioned length of the lateral pins 17, they enter the two external recesses 10 of the locking element 6, but do not protrude into the

Recess 8 in the base 3.

In principle, it is not necessary to make the recesses 10 continuous; the recesses 10 can also be designed to be closed on the side opposite the insertion opening. The cross-sectional shape of the recesses 10 and the pins 17 adapted to them can be varied in order to only fit specially designed pins 17 and recesses 10 with one another

To be able to intervene.

FIG. 5 shows an embodiment of a holder 1 in which the locking elements 6 also assume the holding function for the lower edge of the panel 2. For this purpose, extensions or projections 14 are formed on the locking elements 6, which extend over the inner edge 24 of the frame part 5 or protrude over it. These projections 14 are formed by sections of the essentially circular end face 9 of the locking element 6 and have

AT 412 864 Β zen recesses 19 which are aligned with the inner edge 24 of the frame part 5 and delimit the projection 14. These projections 14 do not stand in the way of a rotation of the pin-shaped locking element 6.

7, 8 and 8a can be seen on the back of the pad 3 formed Verriege5 treatment lugs 20, which prevent rotation of the locking part 7 to a

Only allow opening with a suitable tool 15.

The position of the recesses 10 can be central or peripheral: the shape of the widening head of the locking element 6 can be selected differently, in particular in the edge region 11; a rotationally symmetrical design is advantageous.

A simple and easily manageable structure of the tool 15 provides that the recesses 10 in the locking element 6 or the pins 17 on the end face 16 of the tool 15 are arranged along a straight line.

A simple structure results when the axis of rotation of the locking element 6 has a central, preferably continuous, recess 10. This central recess 10 is used to position the tool 15, which can have a longer central pin 17 for this purpose.

The holder 1, in particular the webs 4 and the locking element 6, consist of plastic which has a certain elasticity.
