Description

WIN D OW MOUN TIN G

The present invention relates to a mid-frame mounting for fastening of a window hinge to a window frame comprising an internal, at least partially open, casing part arranged to be inserted in a boring in the side edge of the window frame, and also fastening to the same, and where the casing part is arranged to lockable receive a pintle of the window hinge, the casing part comprises a collar with a spring arranged, at least, to partially encompass and to retain said pintle in the mid-frame mounting so that it can be released.

Known mid-frame mountings are, in the main, formed in a long shape that are screwed into a cut out/boring in the side edge of the window frame, and which comprise a gliding locking part or one-sided spring which clamps against parts of the pintle of the window hinge. To lock the pintle in the mid-frame mounting, the locking part is pushed to one side of the pintle and is thereafter locked by tightening a screw or the like. Release is carried out the opposite way, i.e. the screw is made loose and the locking part or the one-sided spring is pulled away from the pintle.

From prior art is known, among others from a product data sheet from lntropia AS "Middle-mounting with locking loop", a middle-mounting with a locking loop in the form of a U-shaped spring which is placed in a collar-like casing part and where a groove of a fitted pintle constitutes locking of the pintle when it is pressed into the casing part of the mounting. From a product data sheet from Steelform Scandinavia AS "Middle-mounting with automatic locking", a mid- frame mounting where the casing part is made up of a collar-like construction and with elastic fastening appliances is known. Furthermore, from a product data sheet from AS Spilka Industry "Mid-frame mounting", a mid-frame mounting with a pintle catch is known.

With the present solution one aims to provide a considerably simpler and better construction. With the mid-frame mounting according to the invention a solution is provided which is independent of the choice of profile of the side frame, something which ensures that it is very simple for the factories to use the mounting. Furthermore, the cutting out/boring for the mounting takes place in one operation, something which is a great advantage for the window producers. The mounting is screwed in place to the frame and normally does not need to be dismantled again. At the coupling together of frame and casing, the pintle of the window hinge is pressed into the mid-frame mounting and the pin is then locked by a spring means. This results in a coupling which is simple to produce.

The spring in the mid-frame mounting is constructed in such a way that it shall retain its elasticity, and preferably be clamped in the bottom of the slit/groove in the pintle of the hinge. The spring means is made in one part to achieve maximum spring characteristics, and is in addition, easy to fit when the mounting is mounted together.

An opening or slit is made in the mid-frame mounting, where one must use a tool that forces the spring apart, for it to be possible to dismantle the hinge and the mid-frame mounting.

The shape of the spring means it engages at least two sides of the pintle, something which is previously not known from similar mountings. The advantage with this is that a very good connection to the groove in the pin is achieved, something which makes the mounting much safer. It is also a huge advantage that the mounting becomes considerably stronger as one gets the forces more evenly distributed on the mounting than with a single spring engagement point.

In one preferred embodiment the mid-frame mounting is circular or round, and because of the round shape, the mounting can be rotated and fastened in different positions. This is to make it easier to release the pintle during dismantling of the frame and gives the best possible location of the fastening screws. This also means that the mounting can easily be adapted to different hinges and profile systems. The round shape also provides the advantage that one can rotate the mounting, so that one gets a favourable location for the fastening screws according to the profile.

A preferred embodiment of the invention is characterised by the characteristic in the independent claim 1 , in that the spring of the mid-frame mounting is arranged to engage on at least two sides of a groove around the pintle, and that the collar of the casing part is shaped in a circular form and incorporates an outwardly extending, circular flange, in which the spring is placed, and a lid that covers both the spring and the collar, with the lid comprising a central opening for insertion of the pintle and also an opening or slit for access to at least parts of the spring.

Preferred alternative embodiments are characterised by the dependent claims 2-8. The spring rests preferably in the collar and is in the main arranged to be snapped onto at least two sides of the pintle. The spring can be formed in a partially circular shape with a bottom opening from which two legs run in parallel in toward the middle where the legs are arranged to be clamped against said groove in the springing pin, and where a lower part of the legs can be curved in towards each other and run on at least partially parallel.

In an alternative embodiment, the spring can be formed in a mainly U-shape with two legs, where the part of the legs that make up the main part of the U- shape is arranged to be clamped against said groove in the pintle, and where a lower part of the legs can be curved in towards each other and run on at least partially in parallel.

The lid can comprise an opening or a slit, in which the parallel parts of the lower, curved-in legs are visible and are accessible.

The casing part which is arranged to be inserted into the boring of the side edge of the window frame, is preferably shaped in a circular-cylindrical cup form, the collar has preferably a larger diameter than said cup form and the lid is correspondingly preferably shaped in a circular form and comprises openings to receive securing means for fastening of the mid-frame mounting to the window frame.

Said collar can comprise a number of pins/fastening points arranged for retention of the spring. At least one of said pins can comprise an upper, outwardly extending, additional pin arranged to fit into a corresponding opening in the lid.

The invention shall now be described in more detail with the help of the enclosed figures, in which;

Figure 1 shows a mid-frame mounting according to the invention, seen from the side.

Figure 2 shows a window hinge for connection to the mid-frame mounting. Figures 3 and 4 shows a variant of the mid-frame mounting according to the invention, without a lid.

Figure 5 shows a second variant of the mid-frame mounting according to the invention, without a lid.

Figures 6 and 7 show respective variants of a spring to be used in the mid- frame mounting according to the invention.

Figure 8 shows a variant of a lid to be used in the mid-frame mounting according to the invention.

The figures show a mid-frame mounting 20 for fastening of a window hinge 12 to a window frame (not shown). The mid-frame mounting 20 comprises an internal, at least partially open, casing part 22 arranged to be inserted into a boring in the side edge of the window frame, and for fastening of the mid-frame mounting to the side edge. The casing part 22 is arranged to receive a pintle 14 of the window frame 12 so that it can be locked. Said pintle 14 is, in the main, formed in a known way, but can, if not already produced, comprise an outer conical part 18 to ease the insertion and retention in the casing part 22.

The mounting together of casing and frame is, in the main, carried out in a known way and is assumed to be known by one skilled in the arts. This is also the case for the construction of the window hinge. However, what separates the present invention from known solutions is the fastening of the pintle in the mid- frame mounting. After the mid-frame mounting is fastened to the side edge of the window frame, preferably in a suitable cut out/bored out groove, it is not necessary to regulate or rearrange the mid-frame mounting during the fastening of the window hinge, as this is snapped into place in one operation.

The casing part 20 comprises a collar 24 with a fitted spring means, which can be comprised of a spring or another elastic element, and which is arranged to at least partially encompass and retain said pintle 14 in the mid-frame mounting 20 so that it can be released. The spring is fitted in the mid-frame mounting 20 so that it can press against, and retain, the pintle with the built-in spring force as the sole influencing appliance, i.e. it is not necessary to tighten or loosen screws on the mid-frame mounting to mount or dismantle the window hinge. The spring means/spring 40;50 is consequently arranged to press against and lie in at least parts of a groove 16 in said pintle 14. More precisely, the spring 40; 50 lie in the collar 24 and is arranged to be snapped into position in at least two sides of the pintle 16. To hold the spring in place, the collar 24 of the casing part 22 is formed in a circular shape, or approximately circular shape, and encompasses an outwardly extending circular flange 26, in which the spring 40;50 is placed, and a lid 30 that covers both the spring 40;50 and the collar 24.

Figure 3 shows the pintle 14 being forced into the mounting (the lid is removed to simplify the illustration). The end of the pintle, with the conical pin part 18, forces the spring outward. Thereafter, as shown in figure 4, the legs of the spring are snapped around at least parts of the groove 16 in the pintle.

Two alternative embodiments are shown in this application, but it must be understood that springs of different shapes than what is shown here can also be used. In an alternative embodiment, as shown in figure 6, the spring 40 is formed in a mainly U-shape with two legs 42,44. The part of the legs that constitutes the main part of the U-shape are arranged to be clamped against said groove 16 in the pintle 14. The lower parts of the legs 42,44 are curved in toward each other and run on at least partially in parallel.

In a further preferred alternative embodiment, as shown in perspective in figure 7, the spring 50 is formed with a partially circular shape 52 with a bottom opening 54, from where two legs 56,58 run in parallel in toward the middle. These legs are arranged to press against said groove 16 in the pintle 14, as shown in figure 5. As in the previous embodiment, the lower parts of the legs 60,62 are curved in towards each other and at least partially run on in parallel.

The aim of the lower, curved-in parts of the two legs is that they shall be visible and accessible in an opening or slit 32 in the lid 30, where a tool can be used to force the spring legs apart, to be able to dismantle hinges and mid-frame mountings.

The casing part 22 is, as mentioned, arranged for insertion in the boring in the side edge of the window frame and can be shaped in a circular-cylindrical cup form, with an inner conical section corresponding to the conical part 18 of the pintle. In one embodiment, the collar 24 has a larger diameter than said cup form and lies in a cut-out in the side edge of the window frame. Correspondingly, the lid 30 must be shaped with a similar form i.e. preferably circular form, to fit into the cut-out, and the lid comprises a number of openings 34,36 to receive securing means for fastening of the mid-frame mounting 20 to the window frame. Furthermore, the lid 30 encompasses a central opening 33 for insertion of the pintle 14.

Furthermore, the collar 24 can comprise (as shown in figure 5) a number of pins 28 arranged to retain the spring 50, in that the legs or the partially circular parts lie against said pins, so that the spring can not be rotated. For the same purpose, the collar 24 can, in addition, comprise a spacer/fastening point 27. At least one of said pins 28 can comprise an upper, outwardly extending, additional pin 28a, arranged to fit into a corresponding opening 38 in the lid 30. Alternatively (as shown in figures 3 and 4), a spacer/fastening point 29 for retention of the spring 40 can be provided in the collar 24.
