Description

Technical area

[0001] The present invention relates to a telescopic device for burglar-resistant securing of window and door openings according to the preamble of claim 1. State of the art

[0002] According to the state of the art, retrofittable, mechanical security devices in the form of multi-part locking devices for window and door openings have recently become available. These are typically attached to the outside of the window frame and, in some cases, also to the window sash. The main disadvantage is that these known security devices are very complex in design and require considerable installation effort on the window frame and sash.

[0003] In the utility model DE 20 2016 101 284 A1 a device for the burglar-resistant securing of window and door openings is known, which comprises at least one tubular security element which can be mounted between at least two holders on opposite reveals of a window or door opening and which can be reversibly arranged essentially parallel to the window plane, wherein at least one holder has a receptacle for the insertion of a first end section of the security element directed in the longitudinal direction of the security element, which is designed such that the security element can be arranged within the receptacle essentially parallel to the window plane.

[0004] Telescopic window locks are already known from the state of the art. These include various developments and designs aimed at increasing window security, but less focused on user-friendliness. Some models are very cumbersome to handle, especially if they require frequent installation and removal. This can lead to users not using the lock regularly, which compromises safety.

[0005] Although many well-known models promise easy installation, difficulties can still arise in some cases, especially if the window frames are non-standard or if there are structural peculiarities. Well-known telescopic window locks may also not be suitable for all window types or sizes, which can limit their applicability.

[0006] Overall, it is therefore often necessary to weigh up the advantages and disadvantages of telescopic window locks and, if necessary, to use them in combination with other security measures to ensure comprehensive protection. Description of the invention

[0007] The object of the present invention is to provide a device which eliminates the aforementioned problems and which is suitable for creating a security device which prevents burglary and, in particular, the prying open of a window or door opening, in which the security element can be attached to any window or door opening in a simple and uncomplicated manner and at the same time securely.

[0008] According to the invention, the above object is achieved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments and further developments of the device according to the invention are specified in the dependent subclaims. Brief description of the drawings

[0009] Further objects, features, advantages and possible applications of the device according to the invention will become apparent from the following description of an embodiment with reference to the drawings.

[0010] The drawings show Fig. 1 the device according to the invention in an advantageous embodiment in perspective view; Fig. 2 the locking device in perspective view; Fig. 3 the device in side view. Implementation of the invention

[0011] As from Fig.1, the device 1 according to the invention comprises at least one tubular securing element 12 which can be mounted between at least two holders 10, 11 which are opposite one another and which can be reversibly arranged essentially parallel to the window plane, wherein at least one holder 10 has a receptacle 100 for the insertion of a first end section of the securing element 12 in the longitudinal direction of the securing element 12.

[0012] According to the invention, the present device is characterized in that the tubular securing element 12 is formed from at least two telescopic elements 120, 121, comprising at least a first tubular telescopic element 120 with a longitudinal axis LA and a plurality of locking receptacles 1200 arranged at a distance along the longitudinal axis LA of the first telescopic element 120, as well as at least one second tubular telescopic element 121, in which the first telescopic element 120 is displaceably mounted, and at least one locking device 122 located on the second telescopic element 121 with at least one locking element 1220, which can be brought into engagement with the locking receptacles 1200 on the first telescopic element 120 for the non-displaceable locking of the first telescopic element 120 on the second telescopic element 121 in different positions.

[0013] In a particularly advantageous embodiment of the invention, the locking device 122 comprises a locking element 1220 which is designed to engage in the locking receptacles 1200 and which is spring-loaded.

[0014] Here, the locking device 122 can comprise a pressure piece 1221 for actuating the locking element 1220, which is reversibly fixed in a locking position when the locking element 1220 is pressed into a locking receptacle 1200.

[0015] Furthermore, it is advantageous if the locking device 122 is designed such that the locking element 1220 is unlocked again when the pressure piece 1221 is actuated.

[0016] In a further particularly advantageous embodiment of the invention, the locking device 122 comprises a lock, wherein the locking element 1220 designed to engage in the locking receptacles 1200 can be locked and / or unlocked in a locking position by means of a key.

[0017] In a further embodiment of the invention, the lock is designed such that by actuating the locking element 1220 on the side opposite the locking element 1220, the locking device 122 is locked by means of an extendable pin- or bolt-like locking element, wherein to unlock the lock the locking element is unlocked by means of the key, whereby the locking element moves back again.

[0018] The locking element 1220 can preferably be designed as a pin or bolt and the locking receptacles 1200 as a hole, opening and / or recess on the first telescopic element 120. QUOTES CONTAINED IN THE DESCRIPTION
