EP2746496A2 - Securing device for a window or door handle - Google Patents

Abstract

The device has a cover (6) enclosing a handle (1) in a mounted position and comprising two locking elements (9). A lock (7) is provided secure the cover on the handle in mounted position and release the cover from handle for removing cover from handle. A counter portion (5) is located on the handle, a handle fixture, a door or window. Counter portions are matched and interacted with the locking elements. One locking element is a locking bar (10) of the lock.

Description

The invention relates to a security device for a window or door handle against unauthorized operation according to the preamble of claim 1. It is now common to offer as burglar protection and / or child safety window and door handles also lockable with integrated cylinder lock. However, if the existing window or door handle is not or can not be replaced with a lockable one must resort to additional locking devices.

For example, shows the CH 689 871 A5 a safety device of an armored door of shelters, in which a removable cover and the handle itself is penetrated by a closure part, which can then be locked on the outside of the cover with a separate lock. The design is massive and relatively expensive due to their use for armored doors. For residential doors or windows their use is not practical because of the at least three separate parts, namely cover, lock and armored lock lying around when not in use as individual parts.

The DE 195 17 833 C1 teaches to secure a window or door handle against unauthorized operation by means of two covers, which are adapted and fixed by locking screws to the handle height and can be completed if desired by a cylinder lock. The adaptation and fixation of this device is also expensive. In addition, several parts are available again, which must be accommodated in Nichtgerbrauch.

In practice, the need for handle locking devices has been found in particular in so-called flat handles, which are used for example in folding systems, where the folding of the individual elements and their small distance in the folded state does not allow normal high-building window or door handles. In flat handles therefore usually no locks can be used directly, as is the case with lockable window or door handles. To secure such handles, the state of the art has hitherto offered no solution which not only fulfills the purpose of securing, but is also optically as restrained as possible.

The invention is therefore an object of the invention to provide a security device for window or door handles, which easily prevents unauthorized operation and can be easily stowed in the unused state. This object is achieved by a securing device having the features of claim 1.

By forming the cover with at least two locking elements, which interact with corresponding counterparts on the handle, handle fitting and / or window or door, and by the formation of at least one of these locking elements as a latch integrated in the cover lock the securing device requires only a single removable Part, namely the cover, which can then be made accordingly slim and flat. The fact that the lock, in particular a cylinder lock, is accommodated in the cover does not affect the securing device to the requirements Small depth of the handle in folding systems, since the cover including lock is removed when such a system is opened and folded.

A preferred firm connection of the lock with the cover ensures that no losable items lying around when not using the securing device. For solid attachment of the securing device, it is advantageous if one of the counterparts to the locking elements is a firmly connected to the window or door closing piece. In a further preferred embodiment, the bolt of the lock and / or its counterpart may have a ramp and at least one of these two parts in the direction against the other be spring biased, so that it can retreat against the spring pressure. This makes it possible to put on the cover even when the cylinder lock is closed, since the latch of the lock or its counterpart is then pushed back by the ramp and at the end of the ramp by the spring tension again jumps out to the fixed connection. Only to open the safety device then the lock must be actively unlocked.

In a further preferred embodiment, the counterparts to both locking elements are juxtaposed to the window or door and are functionally identical, i. functionally symmetrical shaped, so that the cover can be placed twisted if desired by 180 °. If the lock is located on one side of the cover, then it can be freely selected whether the lock should sit down or up.

Due to the simple embodiment, in which the essential elements are integrated in the cover, a slim and shapely design can be realized, which can not visually emerge an inserted security device according to the invention. Nevertheless, the system is safe and easy to use.

Further advantages and details emerge from the subclaims and an embodiment of the invention shown in the drawings, which will be described below; show it:

In the Fig. 1 illustrated situation shows a flat handle 1, which is mounted in a handle plate 2 on a frame member or a window or a door 3. Below the handle 1, a counterpart as a closing piece 4 is screwed onto the frame element 3, with the locking elements shown in the following figures a belonging to the safety device, in Fig. 1 not yet attached cover 6 cooperates. As a further counterpart 5 is the upper end of the handle 1, which in any case to allow a tilting of the handle has a bevel, which can be engaged behind. The cover 6 includes a cylinder lock 7, which can be operated with a key 8.

Fig. 2 shows the situation in which the cover 6 is placed over the flat handle 1. In this case engages behind a locking element 9, which is arranged on the inside at the upper end of the cover 6, with a projection formed by the upper end of the handle 1 counterpart 5. The lock 7 is open, ie its not visible here bar is in the position " open or retracted. As a result, the cover 6 can be placed flat on the frame element 3, even at the lower end Fig. 3 shows.

Fig. 4 shows how the now visible latch 10 of the lock 7 by 180 ° rotation of the key 8 from the position "open" or "retracted" from Fig. 3 in the position "closed" or "extended" in Fig. 4 emotional. If the bolt 10 as shown has a ramp 11 and (not visible here) in the direction of arrow 12 is spring biased movable, a mounting of the cover 6 also at closed castle 7 done. Then pushes the previously extended latch 10 when slipping over the cover 6 on the flat handle 1 in contact with the counterpart 4 automatically in the position "open" or "retracted" and jumps in the end position by spring support back to the "closed" or "extended" as in Fig. 4 shown back.

Fig. 5 shows that in the preferred embodiment shown here, the cover 6 can be placed rotated 180 ° if desired, since here the two counterparts are arranged opposite to the frame element 3 4.5 and - albeit not identical, so by corresponding projections or Undercuts, however - functionally shaped. Thus, the position of the cover 6 with "lock down" or "lock up" can be freely selected, for example, depending on the size of who wears the cover, for maximum convenience.

Only for completeness, the show Fig. 6 and 7 the security device with the key removed to fulfill the function of an access protection or an operator lock.

In the mounting variant of the cover of Fig. 5 and 7 could be formed in an alternative, not shown embodiment, the lower locking element by a projection of the cover 6 (instead of the element 9), which engages in a formed as a recess counterpart in the window, the door or the frame profile 3.

The securing device according to the invention is easy to handle and by the ability to attach the counterpart 4 subsequently on the frame member 3, also retrofitted. If the handle 1 can be designed differently at the upper end and thus can not form the counterpart 5, this can for example also be formed by the lateral and upper flanks of the handle plate or handle fitting 2, which can cooperate with the inner walls of the cover 6 in exactly fitting design and thereby prevent twisting of the cover together with the handle 1.
