Abstract

The invention relates to a security device for the sliding sashes (2, 3, 2', 3') of a sliding door or a sliding window (1). According to the invention, the sliding sash (2, 3 or 2', 3') has a bottom frame section (14, 15) which frames the lower edge area of the actual sash (2, 3 or 2', 3') and which has two limb sections (14', 14''). Said limb sections fit laterally on the sash (2, 3 or 2', 3') and are connected to each other at least in sections by a web segment (17). A locking catch (18) is provided for anchoring the frame section (14, 15) on a guiding web (12, 13) of a bottom guide rail (5), said catch snapping into a longitudinal detent recess (19) on the guiding web (12, 13).

Description

Security device

The invention relates to a securing device for a sliding sash of a sliding door or a sliding window, the sliding sash having a lower profile border enclosing the lower edge region of the actual sash with two profile legs lying laterally on the sash, which are connected to one another at least in sections by a web.

For the assembly of a sliding sash frame for sliding doors or sliding windows, mostly profile sections are used that cover the actual sashes, e.g. Laminated glass panels, border on the edge, and which are accordingly also referred to as profile edging. As a rule, horizontal and vertical profile sections in the corner areas of the frame are connected to one another via coupling sections, preferably made of plastic, cf. for example the AT 390 473 B, where the use of coupling blocks both for connecting half profiles for a - e.g. lower horizontal - profile edging and for connecting this profile edging with vertical profile sections is described. The two half profiles do not touch each other directly and are therefore thermally insulated from one another. The connecting blocks are essentially H-shaped in cross-section, and the two vertical H-legs are inserted into grooves in the half-profiles, whereas the horizontal web fulfills the connecting function and moreover preferably has slot recesses in which rollers are mounted.

The horizontal frame profiles are thus rollable - or slidable - attached to a lower guide rail with a guide bar. In order to hang the sliding sash into the upper and lower guide rails, a certain amount of play (in the order of magnitude) is necessary because the sliding sash is first inserted into the upper guide rail in an approximately vertical position, after which it is pushed over the lower guide web is pivoted into its vertical position and is finally placed on the lower guide web; this upper play has a disadvantageous effect after insertion: the free space remaining after the respective sliding sash has been placed on the guide web between the upper edge of the upper horizontal edging profile of the sliding sash and the upper guide rail of the stick frame enables the sliding sash to be lifted afterwards, which entails both a risk of unintentional lifting and tipping of the sliding sash and problems with burglar resistance.

It is therefore the object of the invention to remedy this situation and to provide an anti-lift and anti-tilt device for sliding sashes which is structurally simple and also offers increased security against burglary.

The securing device according to the invention of the type mentioned at the outset is characterized in that at least one locking catch is provided or can be attached to the underside of the web, which, with an associated guide web of a lower guide rail for the sliding sash, which has a longitudinally extending recess, can be latched or is locked. With this design, the sliding sash is hooked into the upper and lower guide rails during assembly and then fixed with the locking catch on the lower guide rails by latching, so that an unwanted or unintentional subsequent lifting of the sliding sash is no longer possible. The security device is structurally extremely simple, and increased security against burglary is also achieved. The one or more legs of the locking catch snapped into the locking recess (s) of the guide web can slide easily in the locking recess (s) so that the sliding sash is firmly anchored with respect to vertical movement on the guide web is, but can still roll or slide along the guide rail. The web on which the locking catch (s) are attached can, for example, be the web of the known connecting block, but it can of course also be formed by any connecting strip that connects the profile legs of the lower profile frame, this strip also along the entire sliding sash , but can only be attached at isolated points between the profile legs.

Depending on the size (length) of the sliding sash, it is possible to have a locking catch on both ends of each slide Install the sliding door or sliding window or several locking catches distributed over the length of the sliding leaf. However, it would also be conceivable - in the case of small sliding sashes - to use only a single locking catch, approximately in the middle of the lower frame profile.

For stable anchoring, it has proven to be particularly advantageous if the locking catch has two legs with latching hooks and the guide web is designed with two longitudinal latching depressions. In this way, the two snapper legs can snap into place on both sides of the guide bar and thus "clamp" it in between.

A structurally advantageous embodiment of the invention provides that the locking snap is used as a separate component in a recess of the web. In this embodiment, the locking catch is inserted into the recess of the web provided for it after the sliding sash has been suspended in the guide rails and pressed down by hand until it clicks with its leg or its legs into the locking recess (s) of the guide web. The assembly is facilitated in this way in that the locking catch snaps and thereby fixes the sliding sash only after the sliding sash has been properly and satisfactorily mounted on the guide bar. Furthermore, the manufacture of this embodiment is relatively simple and inexpensive, and it is also advantageous that existing sliding windows or doors can also be subsequently secured with locking catches used in this way (if necessary after making recesses if they are not already present).

It is also advantageous if the locking catch has an upper widened plate with which it rests on the edges of the recess. This design enables the locking catch to be pressed into the recess by hand until the legs snap into the recess in the guide bar, and at the same time, the plate resting on the edges of the recess prevents it from being pressed too deeply. Since the upper widened plate can be relatively flat, it does not interfere with other components. According to a preferred embodiment of the invention provided that the locking snap is made of polyoxymethylene. This plastic is particularly suitable for the present purpose, since it is very stable in operation with regard to the temperature and strength stresses.

It has proven to be advantageous for the snap catch to be snapped on easily if the upper side of the guide web is rounded. In itself it would also be conceivable, e.g. Depending on the profile of the roller, other cross-sectional shapes are to be provided for the guide web, it being sufficient if the locking catch has run-in bevels at its leg ends.

In order to ensure that the locking catch snaps onto the guide bar in a particularly secure manner and to prevent unwanted release when subjected to greater stress, the latching recesses in the guide bar can be designed like barbs.

Another design option which is favorable with regard to the reduction of the individual parts is that the locking catch and the web are in one piece. With this design, the respective sliding sash is latched to the guide web when it is placed on it.

Here, for example, a version with two legs with locking hooks is also conceivable. For reasons of a particularly stable production, however, it can also be advantageous if the web has a leg with a latching hook which engages in the latching recess of the guide web and has a contact surface on the side opposite the latching hook, the guide web being slidably received between the leg and the contact surface is.

The invention also relates to a guide rail for a safety device according to the invention, with a guide web for the guided support of a sliding sash, it being provided according to the invention that the guide web has at least one latching recess running in its longitudinal direction.

According to a further aspect, the invention also relates to a locking catch for the securing device according to the invention, which is characterized in that two latching legs protrude downward from an upper plate. there it is particularly advantageous if each locking leg is aligned with an inward locking hook at its free ends.

The invention is explained in more detail below on the basis of preferred exemplary embodiments illustrated in the drawing, to which, however, it is not intended to be limited. In detail, the drawings show: FIG. 1 a view of a sliding window; Figure 2 is a vertical section through the outer window of this sliding window along the line II-II in Fig. 1.

3 shows a modified embodiment of the sliding sash with guide web;

Figure 4 is a horizontal section through the connecting block between the two half profiles along the line (IV-IV) in Figure 3;

5 shows an enlarged illustration of a locking catch which can be used as a separate component in a recess in a web; and

Fig. 6 shows a further embodiment of the locking snapper in one-piece design with a web or connecting block of the sliding sash profile in juxtaposition with a guide web with a locking recess into which the leg of the locking snapper can snap.

In Fig. 1 a generally designated 1, conventional double sliding window is illustrated in a schematic view, wherein two glass sliding sashes 2 ', 3' forming an inner window can be seen, which are shown in the closed position in which they face each other overlap, cf. also Fig. 2, in which the two sliding sashes 2, 3 of the associated outer window are shown.

The inner window of the double sliding window 1 shown in FIG. 1, like the outer window (FIG. 2), is provided with a floor frame 4, which has a lower profile guide rail 5, an upper profile guide rail 6 and vertical side profiles 7 , 8 has. This stick frame 4 is inserted in a window frame 9 with a seal, the individual rails and side profiles being screwed, for example, to the parts of the window frame 9 with the interposition of a seal 10 (see FIG. 2).

The lower guide rails 5 have upright, preferably on the top 11 rounded guide webs 12, 13 (see FIGS. 2 and 3), and on these slide the respective glass sliding panels 2, 3 (or also 2 ', 3') with lower horizontal border or Frame profiles 14, 15. The glass sliding panels 2, 3 (or 2 ', 3') are accommodated in channels of the upper guide rails 6 on their upper side. As can be seen in FIG. 2, a certain amount of play 16 remains on the upper side, which is necessary for the assembly, but which enables a subsequent undesired lifting or tilting of the sliding sash 2, 3 (or 2 ', 3'). For this reason, at least one locking catch 18 is provided on the underside of the web 17 of the lower frame profile 14, 15, which is locked in the assembled position with the associated guide web 12, 13 of the lower guide rail 5. For this purpose, the guide web 12, 13 has a latching recess 19 running in the longitudinal direction, into which the locking snapper 18 engages with its ends 18 ', for example barbed, and in this way anchoring the sliding sash 2, 3 (or 2', 3 ' ) on the guide web 12, 13; however, the locking catches 18 can nevertheless slide along the respective guide web 12, 13.

The two guide webs 12, 13 shown in FIG. 2 are in one piece with the lower profile guide rail 5. The two glass sliding panels 2, 3 (or 2 ', 3') set in profile frames slide alongside one another along the guide webs 12, 13 2, the locking catch 18 is connected in one piece to the web 17 of the lower frame profile 14, 15, so as to anchor the glass sliding panels 2, 3 and 2, which are held in profiles held together by the web 17 ', 3' to create.

As can be seen in FIGS. 2, 3 and 5, the locking catch 18 can have, for example, two legs 20, 21 with latching hooks. Fig. 5 shows the at least currently particularly preferred locking snapper 18 of Fig. 3 on an enlarged scale, the barb-like ends 18 'of the two legs 20, 21, which emanate from an upper widened plate 23 and through a recess 22 in Web 17 are inserted, are clearly shown.

The locking catch 18 according to FIGS. 3 and 5 is unlike that according to FIG. 2, used as a separate component in a recess 22 of the web 17. In this locking catch 18, the two legs 20, 21 with locking hooks 18 ', as mentioned, start from the upper widened plate 23, which rests on the edges of the recess 22 in the assembled state. This upper widespread plate 23 is relatively flat. The recess 22 can be made, for example, in a coupling section 24 of a connecting block 25 (cf. FIG. 4), which is used both for connecting half profiles 14 ', 14''for the lower horizontal profile frame 14 and for connecting this profile frame 14 with vertical profile sections 26 serves in the frame corner areas; bearing recesses 27 in which rollers 28 are mounted can also be provided in the connecting block 25. This connecting block 25 essentially has an H shape in cross section (cf. FIG. 3). Finally, at 29 in FIG. 4, for the sake of completeness, a guide block 29 inserted in the vertical frame profile 26 for fitting parts, for example locking-push rods 30, is shown.

In FIG. 3, in addition to the lower profile surround and anti-lift and anti-tipping device, the upper horizontal profile guide rail 6 is also shown, which contains a guide web 32 projecting into a slot 31 on the upper side of the sliding sash 2, 3 (or 2 ', 3') , which is connected to upper horizontal frame profile parts 33. It can be seen again that there is a free space 16 for lifting the sliding sash 2, 3 or 2 ', 3', which is required when installing the sliding sash 2, 3 or 2 ', 3'.

FIG. 6 shows a modified securing device, the locking catch 18 and the web 17 of the connecting block 25 being in one piece. The web 17 has in particular a leg 20 'with locking hooks 18' which snaps into the locking recess 19 of the guide web 12 '. On the side opposite the latching hook 18 there is a contact surface 34, the guide web 12 'being slidably received between the leg 20' and the contact surface 34 in the operating position. This contact surface 34 can possibly also be formed with a sliding strip 35, so that the guide web 12 'on the contact surface 34 is particularly low-friction.
