Abstract
Description
- The present invention relates to an assembly of elements forming part of the operating mechanism for a tilt-and-turn type window fixture, that is, with a sash rotatable on combined bottom and side hinges.
- To ensure their correct operation, conventional tilt-and-turn window fixtures need to incorporate a considerable number of primary accessories, i.e. components which act directly in the operation and manoeuvre of the sash (e.g. handles, open and shut control rods, stops or catches etc.), and secondary accessories serving to secure or lock the primary accessories one in relation to another.
- Two opening systems are adopted currently for these dual-function fixtures, which reflect two clearly definable constructional approaches: the one may be referred to as "turn-tilt" (traditional), and the other as "tilt-turn", the dissimilarity consisting solely in the operating position of the handle, which is determined clearly enough by a different arrangement of the primary accessories mentioned above.
- Whichever the system, the closed position of the sash coincides with the return of the handle to a position of vertical alignment, with the heel of the handgrip directed downwards; from this same position, rotation of the handle through 90°, i.e. substantially horizontal in relation to the fixture as a whole, enables a "turn-tilt" sash to be swung on its side hinges, and a "tilt-turn" sash to tip forward in the manner of a fanlight.
- A further rotation of the handle through 90° from horizontal back to vertical (though in this case with the heel of the handgrip directed upwards) will enable the "turn-tilt" sash to tilt, and the "tilt-turn" sash to swing.
- According to circumstances, naturally enough, each individual manufacturer has opted for one or other of these two constructional approaches, whether by reason of necessity (not least in view of the stock considerations) or of the market at which the end product is targeted. Beyond the mere duplication of manufacturing and inventory operations to cover two entire ranges of components, however, the drawbacks of such a division between two different systems become most apparent at the moment of installing the tilt-and-turn fixture, inasmuch as the decision as to which system is adopted must be made prior to installation; currently indeed, it is not possible to change over from one system to another with work already under way, and selection a priori is thus an unavoidable requirement.
- Accordingly, the object of the present invention is to overcome the drawbacks in question through the adoption of an assembly of elements forming part of the primary control mechanisms for a tilt-and-turn window fixture, whereby the mode of operation of the handle can be altered simply and swiftly, and without modifying the construction of the fixture, even after installation.
- The stated object is realized in an assembly of elements as characterized in the appended claims, the two essential features of which are a bottom locating element slidably associated with the fixed surround frame of a window fixture, adjustable for position in relation to the bottom locking element of the moving sash and affording a vertical stop positioned to interact with a corresponding bottom catch, and a top locating element associated with the sash and consisting in two distinct components: the first, a base of which one end affords a pair of vertical stops placed to interact with the catch of a top stay rod, and the remaining end a seating in which the second component is insertable to an exact fit; the second affording a further pair of stops positioned to interact with the same top catch, and insertable in the first in either of two different positions, the one rotated through 180° from the other, in such a manner as to alter the distance between the respective pairs of stops and thus change the pattern of interaction between the locating element and the catch.
- The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which:
- fig 1 is the schematic frontal elevation of a fixture incorporating the assembly of elements according to the present invention;
- figs 2a-b-c are identical views of the top part of a fixture as in fig 1, illustrating three different operating configurations of a "turn-tilt" system;
- figs 3a-b-c are identical views of the top part of a fixture as in fig 1, illustrating three different operating configurations of a "tilt-turn" system;
- fig 4 is an enlarged detail of the bottom part of a fixture as in fig 1, illustrating one of the open positions of the "tilt-turn" sash;
- fig 5 is the section through V-V in fig 4;
- fig 6 shows one of the elements according to the present invention, in plan from above, positioned for "turn-tilt" operation;
- fig 7 shows the element of fig 6, in plan from above, positioned for "tilt-turn" operation.
- With reference to the drawings, an assembly of elements according to the invention is applicable to window fixtures designed for tilt-and-turn type operation, essentially comprising a fixed
surround frame 1 and a movingsash 2. The fixture is fitted with at least one first locating element 3 (fig 1), positioned along the upright side 2a of thesash 2 farthest from that connected by way of hinges (not illustrated) to thefixed surround frame 1, and in the case of the sash illustrated by way of example (which would be of notable dimensions), fitted with two such elements denoted 3 and 4. Eachelement relative projection respective catch element rods sash 2 is locked and released; therods external handle 7 that can be rotated between a plurality of stable positions (three, in effect), and associated with flexible transmission elements denoted 40 each consisting in a length of wire rope (one of which is indicated schematically in fig 4) slidably accommodated in arelative guide element sash 2. - The
ropes 40 serve to operate respective top and bottom locking and bearingelements catch top locking element 10 consists in astay rod 12 pivotably associated with at least two distinct centres afforded by thefixed surround frame 1 and thesash 2, respectively, in such a way as to limit the travel of the sash when tilted. 13 denotes a bottom locating element associated with the fixedsurround frame 1, insertable in a channel 14 afforded by the latter and slidably adjustable for position in relation to the bottom locking and bearingelement 11. Theelement 13 in question consists in a block 22 (see figs 4 and 5) affording afirst profile 23 underneath, slidably engaged in the channel 14, and asecond profile 24 uppermost, directed toward the locking and bearingelement 11, which affords passage to therelative catch 11a when thehandle 7 is rotated through the operating positions. Theblock 22 also comprises a first vertically disposedlateral stop 15 designed to restrain thecatch 11a whenever thehandle 7 is rotated into a particular operating position (in a preferred embodiment, thestop 15 and thecatch 11a will exhibit substantially matching profiles). Theblock 22 is secured in place by first locking means 16 interacting between thefixed surround frame 1 and the locatingelement 13, which in the example of the drawings consist in a setscrew 31 (fig 5) passing through a corresponding socket 32 disposed transversely and skew in relation to theelement 13 in such a way that the screw interferes with the inside of the channel 14. - 17 denotes a top locating element, in this instance associated with the top of the sash 2 (see figs 6 and 7), attached to what is in effect the 'train' of parts set in motion by the flexible transmission means 40; the
element 17 in question consists in twodistinct component parts vertical stops 19 on the one hand, positioned to engage thecatch 10a of thestay rod 12, and on the other, aseating 20 stably and snugly accommodating thesecond component 17b of theelement 17, which in turn affords a pair of mutually opposedthird stops 21 serving likewise to engage thecatch 10a. - More exactly, the pairs of
vertical stops relative components element 17 are disposed one on either side of acentral track 25 affording passage to thecatch 10a; theseating 20 afforded by thebase 17a appears as aplate 26 withlongitudinal recesses second component 17b. With theseating 20 and thesecond component 17b thus embodied, one has the advantage that thesecond component 17b can be fitted to thefirst component 17a in two distinct positions (shown respectively in figs 6 and 7), essentially rotated through 180° the one from the other, in such a way as permits of altering the distance that separates the one pair ofstops 19 from theother pair 21, and therefore of obtaining a different position of engagement between these and thecatch 10a in relation to the two operating positions of thehandle 7. - The two
components screws holes 30 afforded by the latter 17b and engaged in tappedholes 29 afforded by the former 17a. - Thus, a window fixture incorporating the elements described above can be installed and used either in "turn-tilt" or in "tilt-turn" mode, given that the
bottom locating element 11, which when thestop 15 and thebottom catch 11a are aligned functions as a second bottom pivot on which to tilt the sash 2 (discernible from fig 4, which illustrates an open position of the "tilt-turn" type fixture), and the top locatingelement 17, which serves to restrain or release thecatch 10a of thestay rod 12, can both be adjusted for position in relation to the corresponding catches. - Figs 2a, 2b and 2c illustrate the configuration of the top locating
element 17 in relation to the three positions of thehandle 7, respectively with the sash a) closed and the handle vertical, b) open in turn mode and c) open in tilt mode ("turn-tilt" type system), in which thesecond component 17b is positioned with the respective pair ofstops 21 immediately adjacent to thestops 19 of thefirst component 17a; thecatch 10a is restrained by thestops 19 of thefirst component 17a in the first position of the handle and by thestops 21 of thesecond component 17b in the second position, and free to emerge from the fixedsurround frame 1 in the third position. - Figs 3a, 3b and 3c illustrate the operation of the
selfsame catch 10a in the case of the "tilt-turn" type fixture, likewise in relation to the three positions assumed by thehandle 7, respectively a) with the sash closed, b) open in tilt mode and c) open in turn mode. In this instance, thesecond component 17b of the locatingelement 17 is rotated to distance the relative pair ofstops 21 from thestops 19 of thefirst component 17a; accordingly, thecatch 10a is restrained by thestops 19 of thefirst component 17a in the first position, free to emerge from the fixed surround frame in the second position, and restrained by thestops 21 of thesecond component 17b in the third position. - With this type of adjustment available, it becomes possible to switch the operating positions of the handle mechanism, hence of the external handgrip, according to which of the two tilt and turn systems it is wished to adopt. Moreover, the architecture of the two key elements is such (by virtue of the particular solution disclosed) that the switch can be effected even after the fixture has already been installed: the
bottom locating element 13 can be repositioned in relation to therelative catch 11a simply by loosening thesetscrew 31 and sliding along the channel of the fixed surround, whilst the top locatingelement 17 requires no more than to reverse the position of thesecond component 17b.
