Description

Device for blocking electrical plugs

The invention relates to a device for blocking electrical plugs of electrical devices and systems, such as household, office or industrial devices.

There is often a desire to have devices that operate on one

electrical network must be connected, against undesired '

Secure use. For example, the use of a remote |

visual equipment or a dangerous kitchen appliance by children.

or the unauthorized use of a copier in |

an office. f

The invention is based on the object of a simple and easy to develop an operable device for blocking electrical plugs.

To solve this problem, a device according to the preamble of claim 1 is proposed which, according to the invention, the in

characterizing part of claim 1 has mentioned features.

Advantageous further developments of the invention are mentioned in the subclaims.

The device according to the invention has, in addition to its simplicity and ease of use, the significant advantage that it is for a A variety of different devices can be used and no interventions or installation precautions on the device or the plug required are. The envelope of the device can be dimensioned so that it is suitable for receiving a wide variety of connector types.

Based on the exemplary embodiments shown in the figures, the Invention will be explained in more detail. Show it:

Fig. 1 shows a first embodiment according to the invention in a side section along the line A-A in Fig. 2,

Flg. 2 shows the embodiment according to FIG. 1 in a front view from the left in Fig. 1,

3 shows the lower shell-shaped part of the embodiment according to FIG Fig. 1 in plan view with an inserted plug,

Fig. 4 shows the embodiment according to Figures 1 to 3 in the Representation according to FIG. 1 in the open state,

Fig. 5 is a section along the line B-B in Fig. 1,

6 shows a section along the line C-C in FIG. 3,

however, through both shell-shaped parts, whereby these are moved apart in the axial direction of the lock,

7 shows another embodiment of the device according to the invention.

The device shown in Figures 1 to 4 according to the invention consists of two shell-shaped parts 1 and 2, of each of which has essentially the shape of a cuboid. The two parts 1, 2 fit on their open sides with their edges on top of each other, so that in the superimposed state they have a form box-shaped shell. The interior of this shell is dimensioned so that an electrical connector 5 can be accommodated therein. That Cable 6 of an inserted plug runs in the closed state of the sheath through an opening 7 which is formed by two semicircular recesses 8 in the side walls 11, 12 of the two Parts 1 and 2 is formed.

The two parts 1, 2 are connected to one another on one side of the box-shaped cover via a hinge 4. With the help of this hinge, the two parts of the box can be opened for the purpose of inserting and removing the plug 5, like this is shown in FIG.

To close the cover with the plug inserted, in the embodiment according to FIG. 1 to 6 a slim cylindrical shape

Lock 10 is provided, which in a wall reinforcement 22 of the Part 1 is embedded and fastened in a suitable manner, e.g. by gluing. The cylinder-shaped lock goes through one in the reinforced wall parallel to this wall and perpendicular to the parting line of the box existing hole and protrudes downwards with a Extension 16 out, at the end of which there is a rotatable locking bolt 17 (Figure 6). In the lower part in the sense of the figures 2 there is also a partial wall reinforcement 23 which has an opening 20 into which the extension 16 with the locking bolt 17 can be pushed. The lock can be opened by a Key via a keyhole 13 on side 14 be actuated, the locking bolt coming to lie under the underside 19 of the wall reinforcement 23, for example and thereby closes the box. It is also conceivable that the The locking bar is rotatable in the other direction and thereby in a slot-shaped recess 18 (Fig. 2) on the front Side wall 12 comes to rest. The lock 10 is preferably designed so that the key can only be withdrawn in the locked position (non-revolving key).

Fig. 7 shows another embodiment of the invention in which the hinge 4 lies on a side which runs parallel to the cable of the inserted plug. The castle 10 is in this one AusfUhrungsbeispiel from the outside on the side walls 24 and 25 of the two parts 1 and 2 attached.

The apparatus of the invention is not limited to the illustrated exemplary embodiments%. Multiple modifications within the framework of the disclosed inventive concept3 are possible: ⁱ

For example, a hinge k can be dispensed with if the casing is made of a plastic or another flexible material. In this case, the two side walls 26 and 27 can consist of a continuous homogeneous wall. The shell then consists of a coherent, homogeneous body, with parts 1 and 2 being able to be opened up by bending the rear wall 26, 27 about the axis 4. On the line of axis 4, the wall thickness can be made weaker to achieve easier bendability.

The parts 1 and 2 can have any other shape than that shown in the figures. For example, half-cylinder shapes, hemispherical shapes or half-ellipsoidal shapes come into consideration. Finally, it is also not essential that the half-shells have an inherently rigid shape. The two half-shells together can can also be designed as a bag-like cover made of non-rigid material, which open and close on one side leaves.

In the embodiment shown in the figures, the Heights hl and h2 of the two half-shells can also be different. The height of a cuboid shell can be so low

11/17/1978 20 577 G

that it practically becomes a flat lid. The height of the other half-shell is to be increased accordingly, and the Opening 7 for the cable of the plug is then to be worked into the high-walled part in the form of an elongated hole of a corresponding length.

For better guidance of the two half-shells in the closed state, knobs 30 and corresponding depressions 31 can be attached to the narrow sides of the half-shells lying on top of one another are provided.

It goes without saying that the cover need not be closed on all sides. The shell-shaped parts 1 and 2 can have perforations or also from. consist of a wire mesh-like mesh. It just needs to be ensured that the connector with its steek pins cannot be plugged into a socket through the cover.
