Abstract

The fitting arrangement (1) has a fixing section (2) which is formed for fixing the fitting arrangement at a lifting sliding element. A contact section (13) is formed temporarily during the lowering and the raising of the lifting sliding element on a guiding rail or overlies a section located bottom side or frame lower side. A spring element (8) is formed to counteract the weight of the lifting sliding element temporarily during the lowering and the raising of the lifting sliding element.

Description

The present invention relates to a fitting arrangement for lifting-sliding elements, such as lifting-sliding doors or lifting-sliding windows, which are displaceable along a lower guide rail, wherein the lifting-sliding element from a lowered position in which the lifting-slide element is immovable, in a raised Position in which the lifting-sliding element is displaceable, can be transferred. Furthermore, the invention is directed to such a lift-slide element.

For lifting and moving lifting-sliding elements so-called carriages are usually provided, which are arranged in a formed on the underside of the lifting-sliding element receiving groove and actuated by a coupled for example with an actuating lever drive rod. While in a closed position of the lift-slide element rests with its underside immovably on the bottom side or on a frame base or the like, it can be raised by pivoting the actuating lever attached to the lifting-slide member of the carriage relative to resting on the guide rail rollers of the carriage whereby the lifting-sliding element is even transferred to its raised position and can be moved over the rollers along the guide rail.

In particular, in large-surface sliding elements, which may for example have a weight of several hundred kilograms, which is for the lifting of the lifting-pushing element required force for pivoting the actuating lever is relatively large, so that the transfer of the lifting-pushing element from the lowered to the raised position can not be done with the desired ease. In addition, there is the problem that when lowering the lifting-pushing member from the raised to the lowered position there is a risk that the operating lever from a certain point due to the high weight of the lifting-pushing element automatically jumps upwards.

It is an object of the present invention, a fitting arrangement of the type mentioned in such a way that even with lifting-sliding elements with high weight, a simple transfer of the lifting-sliding element from the lowered to the raised position is possible and beyond the risk of undesirable, automatic, abrupt pivoting of the actuating lever is lowered when lowering the lifting-sliding element.

Starting from a fitting arrangement of the type mentioned above, this object is achieved by a mounting portion which is designed to fasten the fitting assembly on the lifting-slide element, a contact portion which is formed, at least temporarily during lowering and lifting of the lifting-slide element the guide rail or a bottom-side or frame-side located portion, and at least one spring element which is designed to counteract at least temporarily during the lowering and lifting of the lifting-pushing member of the weight of the lifting-pushing member. An inventively designed lifting-sliding element has on its underside a receiving portion in which at least one carriage is arranged, wherein in the receiving portion further at least one inventively designed fitting arrangement is arranged.

The fitting arrangement according to the invention ensures that the force required by a user when transferring the lifting-sliding element from the lowered position to the raised position is reduced by the force exerted by the spring element. By appropriately matched spring elements thus required for lifting the lifting-sliding element force can be adjusted independently of the weight of the lifting-sliding element to a pleasant and easy-to-use value. At the same time it is ensured that when lowering the lifting-sliding element, a part of the weight is also absorbed by the spring element, so that the risk of a sudden upward speeding of the operating lever is reduced.

By attaching the fitting assembly on the mounting portion on the lifting-sliding element can be achieved that the fitting assembly moves after complete relaxation of the spring element together with the lifting-sliding element with upwards and thus the contact portion of the fitting arrangement no longer with the guide rail or the bottom or frame-side section. It can thereby be achieved that when moving the lifting-sliding element no additional, caused by the fitting arrangement frictional forces must be overcome.

According to an advantageous embodiment of the invention, the spring element between the mounting portion and the contact portion is arranged. As a result, a very simple construction of the inventively designed fitting arrangement is possible. In particular, the fitting arrangement via the mounting portion directly in a commonly provided on the underside of the lifting-slide element receiving groove, which also serves to accommodate the carriage, are attached.

According to a further preferred embodiment of the invention, the spring element is designed as a compression spring. In this case, any type of compression springs, such as coil springs, leaf springs or other pressure forces receiving spring elements, usable.

Preferably, two or more spring elements are provided. The number of spring elements can be selected in particular depending on the weight of the lifting-sliding element. In particular, the use of two or more spring elements is advantageous because in this case increases the stability of the fitting assembly and in particular a tilting is avoided.

According to a further advantageous embodiment of the invention, the fitting arrangement for mounting on a provided on the underside of the lifting-slide member receiving portion is formed. Since such a receiving portion, for example in the form of along the underside of the lifting-sliding longitudinally extending receiving groove, usually for receiving the carriage and the carriage connecting drive rod is present, no special cutouts or the like are provided for the arrangement of the fitting assembly according to the invention. The fitting arrangement can thus be retrofitted in a simple manner with existing lifting-sliding elements without special cutouts or the like would have to be generated.

Preferably, the fitting arrangement comprises at least one passage opening extending in the longitudinal direction. If the fitting arrangement according to the invention is arranged, for example, in the region between two carriages, the drive rod connecting the two carriages can be guided through the passage opening, so that the functionality of the carriage fitting is not impaired by the fitting arrangement according to the invention.

According to a further advantageous embodiment of the invention friction-reducing means are provided in the region of the contact portion. These may for example consist of a coating or a separate element with low coefficients of friction and / or comprise rotatably mounted rollers. By the friction-reducing means ensures that a displacement of the lifting-sliding element in the raised position is possible even without great effort, when lifting the lifting-pushing element in the raised position of the contact portion of the fitting assembly is not completely from the guide rail or the bottom side or is lifted off the frame-underside section.

According to a further advantageous embodiment of the invention, the spring element is biased. By selecting a corresponding bias, the force acting against the weight of the lifting-pushing element by the spring element can be set to a suitable value in each case in the desired manner. Preferably, the bias of the spring element is adjustable, so that the same fitting arrangement can be used for different lifting-sliding elements with different weights. As a result, the cost of warehousing and the production of the fitting arrangement according to the invention can be reduced.

According to a further advantageous embodiment of the invention, the fitting arrangement is integrated in a carriage of the lifting-sliding element. Since lifting-sliding elements are usually provided with carriages, which are arranged in receiving grooves formed on the underside of the lifting-sliding element, a simple integration of the inventively designed fitting arrangement in this carriage is possible. If the lifting of the carriage, for example via a pivot lever, so the spring element may be formed, for example, as the pivoting movement supporting spring element, in particular in the form of a arranged on the pivot axis of the pivot lever coil spring.

Further advantageous embodiments of the invention are specified in the subclaims.

Fig. 1 shows a fitting arrangement 1 designed according to the invention, which comprises a flat iron-shaped fastening portion 2, which comprises at its ends in each case a fastening hole 3 for receiving a screw and two threaded bores 4.

In the threaded holes 4, the ends of screws 5 are screwed, which formed by in a base part 6 openings 7 (see Fig. 2 and 3 ) are passed, wherein the screws 5 are each embraced in the region between the mounting portion 2 and the base part 6 of spring elements 8 designed as helical springs.

The base part 6 is formed as an elongated U-profile, which comprises two parallel legs 9 and a connecting portion 10 connecting the two legs, in which the openings 7 are formed.

At the two longitudinal edges 11 of the legs 9 is an elongated contact element 12, whose remote from the U-shaped base part 6 underside is formed as a contact portion 13. In the contact portion 13 extends in the longitudinal direction, a guide groove 14, wherein in addition two the contact element 12 penetrating openings 15 are provided, which are aligned with the mounting holes 3.

At the opposite side of the contact portion 12 of the contact element 12 has two shoulders 16 are formed so from each other are spaced apart, that when assembling the fitting assembly 1, the contact element 11 is arranged form-fitting manner between the legs 9 of the U-shaped base part 6, as is apparent from the Fig. 2 and 3 can be seen.

While the attachment portion 2, the screws 5, the spring elements 8 and the U-shaped base part 6 are preferably made of metal, the contact element 12 is advantageously made of a friction-reducing material, in particular of plastic. In principle, it is also possible that only the contact section 13 consists of a corresponding friction-reducing material, for example a friction-reducing coating. In principle, the contact element 12 can also be completely eliminated, so that the contact section 13 is formed directly on the base part 6. The base part 6 may be open at the bottom, for example, with straight or bent leg ends, or may be formed closed.

Out Fig. 2 It can be seen that the spring elements 8 are in the assembled state of the fitting assembly 1 with lowered lifting-pushing member in a compressed state, so that the heads 31 of the screws 5 to the connecting portion 10 are spaced. While in the embodiment shown, the connection between the mounting portion 2 and the base part 6 via the screws 5, other suitable connecting means, such as rivets may be provided instead of the screws 5. It is also conceivable that, for example, pin-shaped bolts are formed instead of the screws 5 on the attachment portion 2, the free ends of which protrude through the openings 7 in the interior of the U-shaped base part 6 and are provided there with a screw thread on each of which a nut is screwed on.

Furthermore, it is off Fig. 2 to recognize that the fitting assembly 1 comprises a through hole 17 which is defined by the area between the two legs 9, the connecting portion 10 and the contact element 12.

The fitting assembly 1 is in a longitudinal cutout in the lower region of a wing 18 of a lifting-sliding element 19 (see Fig. 4 ) receiving portion 20 is arranged, wherein the upper side of the fixing portion 2 is screwed to the bottom 21 of the receiving portion 20. Corresponding screws not shown are passed through the mounting holes 3 of the mounting portion and can be achieved with a corresponding screw through the openings 15 and with the openings 3 and 15 aligned, formed in the connecting portion 10, not shown openings.

Furthermore, it is off Fig. 2 to recognize that in the guide groove 14 projects a guide lug 22 of a guide rail 24 fixed to the bottom 23, on which the fitting assembly 1 rests in the lowered state.

In contrast, in the raised position after Fig. 3 the fitting assembly 1 is lifted from the guide rail 24, so that a gap between the contact portion 13 and the guide rail 24 is present. The fitting assembly 1 is raised together with the wing 18, wherein the spring elements 8 with respect to the illustration Fig. 2 in a more extended position. The extension of the spring elements 8 is limited by the voltage applied to the underside of the connecting portion 10 heads 31 of the screws 5. In the raised position and the wing 18 is spaced from the bottom 23, so that a displacement of the wing 18 via the in the Fig. 2 and 3 Carriage not shown can be done in a known manner.

From the illustration of the lifting-sliding element 19 after Fig. 4 It can be seen that in the receiving portion 20, for example, two inventively designed fitting assemblies 1 and formed in a known manner carriage 25 are arranged. Furthermore, it can be seen that the carriage 25 is connected via a drive rod 26 with an actuating lever 27 in connection, according to an arrow 28 of a dashed lines shown locking position 27 ', in which the lifting-slide member 19 is in its lowered position in his Open position 27 "is pivotable, in which the lifting-sliding element 19 on the carriage 25 on the guide rail 24 is slidable.

Furthermore, it is off Fig. 4 to recognize that the above the carriage shown on the left 25 connected to the drive rod 26 further drive rod portion 29 is passed through the through holes 17 of the fitting assemblies 1, so as to establish a connection between the carriage 25.

In the following, the operation of the inventively embodied fitting assembly will be described in more detail.

Is the lifting-slide element 19 in its lowered position, as in Fig. 2 is shown, it stands with its bottom 30 on the floor 23 or, in a broader design of the guide rail 24, optionally on this. The fitting assembly 1 is clamped in this case between the guide rail 24 and the bottom 21 of the receiving portion 20, as it is also in Fig. 2 can be seen. The Spring elements 8 are compressed together, so that the resulting spring force of the weight of the lifting-pushing element 19 counteracts.

Is the operating lever 27 of his in Fig. 4 shown locking position 27 'in the open position 27 "according to the arrow 28 is pivoted downward, so in the usual way an increase of the lifting-sliding element 19 by the carriage 25. The force required for lifting, however, is reduced compared to conventional lifting-sliding elements, as a part of the weight force to be lifted does not have to be applied via the actuating lever 27, but is provided as a counter force by the compressed spring elements 8. The lifting of the lifting-sliding element 19 is thus supported by the spring elements 8 until the spring elements 8 are completely relaxed, or, as it is in Fig. 3 is shown until the screw head 31 of the respective screw 5 comes to rest on the connecting portion 10 and thus further relaxation of the spring elements 8 is prevented.

From this point on, the base part 6 is moved upwards together with the lifting / sliding element 19, so that the contact section 13 is released from the guide rail 24, as shown in FIG Fig. 3 can be seen. The fitting assembly 1 is designed so that this separation of contact portion 13 and guide rail 24 only takes place immediately before reaching the raised position of the lifting-sliding element 19, so that the force acting from this point higher weight of the lifting-sliding element 19 is no longer disadvantageous ,

If, due to tolerances, for example in the guide rail 24 or the contact element 12, no complete separation between these two elements over the entire sliding path can be ensured, then Due to the friction-reducing properties of the contact portion 13, a sluggishness in shifting the lift-push member 19 is avoided.

When lowering the lifting-slide member 19, the actuating lever 27 is pivoted against the arrow 28 from the lower to the upper position. Immediately after the start of the pivoting, the contact portion 13 comes into contact with the upper side of the guide rail 24, so that part of the weight of the lift-and-slide member 19 is caught by the spring members 8. In a further lowering of the lifting-pushing element 19 thus applied to the actuating lever 27 force is reduced compared to the case without using a fitting assembly 1 according to the invention, so that the risk of upward flicking of the actuating lever 27 is reduced.
