Description

The invention relates to a handle unit for a component, in particular for a window or a door, comprising a handle, a receiving element, a locking element arranged between the handle and the receiving element and a spacing element arranged between the locking element and the receiving element, the receiving element being attachable to the component wherein the handle has a polygonal pin that can engage the actuation of a locking mechanism in the component, wherein the handle unit by moving the handle in the direction of the receiving element from a locked state in which a position of the handle relative to the receiving element is not changeable , In an unlocked state, in which the position of the handle can be changed relative to the receiving element, the handle can be rotated in the unlocked state about the spacer element, and wherein the locking element in the locked state with a connection nng portion of the handle is engaged.

Handle units of this type are used to open and close a component, for example a window or a door. A movement of the handle actuates the closing mechanism of the component so that it can be opened and closed.

Various measures are known from the prior art in order to secure such handle units against break-ins.

From the EP 0 930 410 B1 an actuating handle is known which can be secured by means of a locking cylinder embedded in the handle to protect against unauthorized access. The lock cylinder can be operated by means of a key.

Handles that can be unlocked by exerting pressure on the handle are from the publications DE 295 18 723 U1 , DE 10 2011 100 591 A1 and DE 101 00 874A1 known. Furthermore disclosed EP 1 420 132 A1 a window handle, which is provided with a predetermined breaking point to prevent attempts to break in.

The invention is based on the object of proposing a burglar-resistant handle unit and a burglar-resistant component which have improved operability.

This object is achieved by a handle unit with the features of claim 1 and by a component with the features of claim 9.

Advantageous embodiments of the handle unit are the subject of the dependent claims.

In the handle unit according to the invention, the connecting section has at least one fixing element which secures the handle against a tilting movement on the spacer element in the unlocked state of the handle unit.

When opening the component, the handle must first be moved in the direction of the receiving element in order to produce the unlocked state. The position of the handle can then be changed relative to the receiving element. This is done, for example, by rotating the handle relative to the receiving element. When the handle is turned, the polygonal pin can be turned with the handle so that the locking mechanism is actuated. The use of a key to actuate a lock cylinder or other aids can thus be omitted. The closing mechanism is actuated by merely moving the handle in the direction of the receiving element and then changing the position of the handle relative to the receiving element.

On the one hand, this operability represents a simple solution to open or close the component, but at the same time it makes unauthorized access by burglars more difficult. The sequence of movements required to open the component is easy to implement from the inside, but difficult from the outside.

The handle advantageously has a spring, the spring being relaxed in the locked state of the handle unit and the spring exerting a restoring force in the unlocked state of the handle unit in order to guide the handle unit into the locked state.

As a result, the handle unit is only guided into the unlocked state of the handle unit by pressing the handle toward the receiving element. At the same time, due to its compression in the unlocked state of the handle unit, the spring exerts a restoring force on the handle, so that the handle unit is automatically returned to the locked state as soon as no further pressure is exerted on the handle in the direction of the receiving element. This also prevents the handle unit from being accidentally left in the unlocked state after the component has been opened or closed.

The handle advantageously has a receptacle in which the spring is received.

For example, the receptacle can be cylindrical, and the spring can, for example, be a spiral spring that is inserted into the receptacle. The spring is thus guided and held in the receptacle.

In an advantageous embodiment, the polygonal pin is received in the receptacle, the spring being fixed by the receptacle and the polygonal pin.

The spring can in particular be fixed between the receptacle and the polygonal pin. Thus, the spring automatically causes a restoring force on the handle relative to the polygonal pin and thus to the receiving element in the unlocked state.

The fact that the connecting portion of the handle engages with the locking element prevents a change in the position of the handle relative to the receiving element.

In an advantageous embodiment, the connecting section can be brought into engagement with the locking element by means of a positive connection. The connecting section advantageously has projections which engage in corresponding recesses in the locking element.

Such a form-fitting configuration can in particular prevent rotation of the handle relative to the receiving element.

When the handle unit is guided into the unlocked state, the handle is guided to the spacer. In particular, the connecting section of the handle is brought out of engagement with the locking element, so that the connecting section surrounds the spacer element. So that the position of the handle can be changed in the unlocked state, the spacer element is designed such that the connecting section cannot come into engagement with the spacer element. The handle is then rotatable about the spacer.

The fixing element can in particular be designed such that it rests on the spacer element in the unlocked state of the handle unit. This prevents the handle from tipping over.

The handle advantageously has a predetermined breaking point, which is arranged in particular in a transition region to a handle neck. In the event that force is exerted on the handle from the outside, for example in order to pull it towards the receiving element in order to produce the unlocked state, the handle breaks at the predetermined breaking point, so that the unlocked state cannot be produced. This is particularly helpful in the event of unauthorized access from outside by burglars and further improves burglar security.

In an advantageous embodiment, the handle unit has a locking device for permanently locking the component. The locking device can be designed, for example, as a clamp. In particular, the locking device can be attached between the handle and the receiving element in order to block the movement of the handle in the direction of the receiving element.

The invention is described schematically below with reference to drawings using exemplary embodiments. In the drawings:

• 1 2 shows a sectional view of an exemplary embodiment of the handle unit according to the invention, which is attached to a window, in the locked state,
• 2nd a sectional view of the embodiment 1 in the unlocked state,
• 3rd a front view of an embodiment of the handle;
• 4th a front view of an embodiment of the locking element;
• 5 a sectional view of an embodiment of the handle unit according to the invention with a locking device and
• 6 a front view of an embodiment of the locking device.

1 and 2nd each show a window F with a handle unit 10th . The handle unit 10th has a handle 11 , a receiving element 12th , a locking element 13 , a spacer 14 and a connecting section 18th with a fixing element 21 on.

The receiving element 12th is at the window F attached, for example with screws not shown here. The window F has a locking mechanism, not shown, into which a polygonal pin 16 engages to actuate the locking mechanism. The polygonal pencil 16 is in one shot 17th of the handle 11 recorded and by the locking element 13 , the spacer 14 and the receiving element 12th guided.

In the recording 17th is also a spring 15 added. The feather 15 is through the inclusion 17th and the polygonal pin 16 fixed. The recording 17th can, for example, be cylindrical or cuboid. The feather 15 can, as in the present example, be designed as a spiral spring so that it can be inserted into the cylindrical receptacle.

The in 1 shown state corresponds to a locked state of the handle unit 10th in which a position of the handle 11 relative to the receiving element 12th cannot be changed. By moving the handle 11 towards the Receiving element 12th can the handle unit 10th in the in 2nd unlocked state shown. The position of the handle is in the unlocked state 11 relative to the receiving element 12th changeable. For example, the handle 11 relative to the receiving element 12th to be turned around. When turning the handle 11 can the polygonal pin 16 with the handle 11 be turned so that the locking mechanism is actuated.

The feather 15 is in the locked state of the handle unit 10th relaxed. In the unlocked state of the handle unit 10th is the feather 15 however, by the handle 11 on the one hand and the polygonal pin 16 on the other hand compresses and exerts a restoring force on the handle 11 out to the handle unit 10th attributed to the locked state.

The handle unit 10th can be moved from the locked state to the unlocked state by, for example, manually pressing the handle 11 towards the receiving element 12th is exercised. When the manual pressure is released, the handle unit 10th by the restoring force of the spring 15 automatically returned to the locked state.

The handle unit 10th has a between the handle 11 and the receiving element 12th arranged locking element 13 on how vividly it is in 4th is shown. The locking element 13 can with a connecting section 18th of the handle 11 be engaged, particularly in 3rd is clearly illustrated.

Around the connecting section 18th of the handle 11 with the locking element 13 to engage, in particular by means of a positive connection, the connecting portion 18th Ledges 19th have, which in corresponding recesses 20th of the locking element 13 intervention. The tabs 19th can for example at a 3 o'clock, 6 o'clock, 9 o'clock and a 12 o'clock position of the connecting section 18th be arranged. By the connecting section 18th with the non-rotatable locking element 13 is engaged, a rotation of the handle 11 relative to the locking element 13 prevented so that a position of the handle 11 relative to the receiving element 12th cannot be changed.

Accordingly, the state in which the connection portion corresponds 18th with the locking element 13 is engaged, the locked state of the handle unit 10th .

If the handle 11 towards the receiving element 12th is moved, the projections 19th from the recesses 20th of the locking element 13 led out so that the connecting section 18th no longer with the locking element 13 is engaged. Then there is a position of the handle 11 relative to the receiving element 12th changeable. This state corresponds to the unlocked state of the handle unit 10th .

In this state, the connection section 18th a spacer 14 surround that between the locking element 13 and the receiving element 12th is arranged. The handle 11 is in the unlocked state around the spacer 14 rotatable.

How especially out 3rd can be seen, the connecting section 18th at least one fixing element 21 on. In particular, at the connecting section 18th two fixing elements 21 be provided. The at least one fixing element 21 secures the grip 11 when the handle unit is unlocked 10th on the spacer 14 against a tipping movement. This ensures that the handle 11 not from the spacer during operation 14 and the receiving element 12th falls or tilts away.

The handle 11 can be a predetermined breaking point 24th have, in particular in a transition area to a handle neck 23 is arranged. The handle breaks in the event of unauthorized use of force from outside 11 at the predetermined breaking point 24th , so that it is not possible to use the handle unit 10th to lead from the locked state to the unlocked state. The resistance of the predetermined breaking point 24th to be selected so that the handle neck can be broken off before the locking mechanism is destroyed or turned off. This prevents actuation of the closing mechanism of the component, so that a possible attempted break-in is not successful.

As in 5 a locking device can be used for uses that require permanent locking of the component 22 be provided. The locking device 22 can in particular between the handle 11 and the receiving element 12th be attached to the movement of the handle 11 towards the receiving element 12th to block.

The locking device 22 can, like from 6 exemplarily emerges as a clamp. The clamp can, for example, two C-shaped legs 27 include that at one end via a joint 26 are interconnected. The thigh 27 can be moved relative to each other by the articulated connection, so that the locking device 22 around the spacer 14 can be placed.

The locking device 22 can also, as in 6 shown on the joint 26 opposite ends of the legs 27 one magnet each 25th exhibit. This ensures that the locking device 22 automatically closes after attachment.

The handle unit described above 10th causes increased burglary security on the one hand and ease of use on the other hand since tools such as a key can be dispensed with in particular. The unlocked state can rather by pressing against the handle 11 getting produced. The locking mechanism of the component can then be rotated by the handle 11 be operated.
