Definitions
- the present invention relates to a drive unit for bottom-hung or tilt and turn window frames, in particular for metal frames.
- the above-mentioned bottom-hung window frames comprise a mobile frame hinged to the lower crosspiece of a fixed frame and a control unit for opening and closing the mobile frame.
- Said means comprise one or two tie rods (according to the size of the frame), each pivoting at a first end in a channel in the section forming an upright of the fixed frame (by means of a suitably shaped rotary tie rod connecting pin), and at the other end at a slide which is slidably connected in a channel in a corresponding upright of the mobile frame.
- the tie rod follows the opening and closing movement of the mobile frame thanks to the rotation allowed by the first fixed pivot on the fixed frame and by the sliding action of the slide along the channel in the mobile frame, thanks to the second pivot point.
- the maximum opening angle possible for the mobile frame is normally given by an end of stroke block fixed in the channel in the mobile frame, which stops the above-mentioned slide during mobile frame opening.
- Another structural addition of these guide and positioning means consists of means for releasing the slide or rotation pin so as to achieve complete rotation of the mobile frame, to allow the glass on the outside of the mobile frame to be cleaned.
- the securing means to the wing are composed of a connection device that is slidable along the wing.
- the device is further equipped with locking and unlocking means that are commonly composed of a wire spring adapted to be housed into the device.
- This device allows, on one hand, a more controlled frame descent, but on the other hand it makes it more difficult for the user to close the frame, since the resistance of the slide is equal in both sliding directions. In addition, it must be remembered that such solutions require frequent adjustments.
- the aim of the present invention is, therefore, to overcome the above-mentioned disadvantages by providing a drive unit for bottom-hung windows which has an extremely simple structure and with the possibility of gradual control of both the mobile frame descent and the mobile frame ascent and closing without the addition of any structural elements compared to conventional drive units.
- the present invention provides a drive unit for bottom-hung windows according to one or more of the appended claims.
- the drive unit in question is used for bottom-hung window frames.
- bottom-hung frames comprise a fixed frame 1 to whose crosspiece 1a a mobile frame 2 is hinged at Y, the mobile frame moving between a closed position (not illustrated), in which it makes contact with the fixed frame 1, and an open position, in which it is set at an angle ⁇ to the fixed frame 1 (see Figure 1).
- the drive means 3 may comprise (in a minimum configuration for small window frames) at least one rod 4, its first end pivoting in a first channel 5 of an upright 1b of the fixed frame 1 and the second end pivoting at a slide 6 which slides, by means of a suitably shaped internal body 7, in a second channel 8 of an upright 2a of the mobile frame 2.
- window frames normally include two units consisting of the above-mentioned elements and positioned on the two uprights of the fixed frame 1 and the mobile frame 2.
- At least one end portion 7a of the internal body 7 of the slide 6 at the point D of connection with the rod 4 has a transversal dimension T which is less than the transversal dimension T1 of the second channel 8. In this way, the slide 6 rocks inside the second channel 8 (see arrow F1 in Figure 6).
- This rocking allows the control, that is to say slowing, of the mobile frame 2 stroke as it moves from the closed position to the open position.
- the slide 6 also comprises means 9 which lock the slide 6 in and release it from the second channel 8, clearly illustrated in Figure 4. Said locking and release means 9 are used to allow the mobile frame 2 to rotate through 180° to allow total cleaning of the external part of the mobile frame 2.
- the locking means 9 form a second pivot point F on the slide 6, offset relative to the point D of connection to the rod 4, and about which the slide 6 rocks.
- the locking means 9 comprise a pin 10 attached to the slide 6.
- the pin 10 has two opposite projections 10a and 10b (forming a sort of cam) and is mobile (see arrow F2), manually and using a special manual grip element 10c, between a position in which the slide 6 is locked, in which the projections 10a and 10b project from the transversal dimension T of the slide 6 and are engaged in the second channel 8, and a position in which the slide 6 is released, turned through an angle E relative to the first position, in which the projections 10a and 10b are within the transversal dimension T of the slide 6, allowing its release from the second channel 8.
- the above-mentioned manual grip element 10c (illustrated with a dashed line) is partially housed in a lowered non-operating position, in a slot 100 in a surface of the slide 6, so as to stabilise the grip element 10c (consisting of a spring) and prevent its unwanted rotation.
- the internal body 7 also forms a mobile frame 2 end of stroke element, upon reaching the angle ⁇ , at a position in which it is at the maximum angle to the second channel 8 (again see Figure 6) and allowed by a stable contact of two opposite end points of the internal body 7 on the second channel 8.
- the rocking of the whole internal body 7 is caused by its particular configuration, with a taper extending towards the outer edge of the internal body 7, at the portion 7a next to the point D of connection to the rod 4.
- the internal body 7 has a portion 7h of one of its sides that is at an angle ⁇ to the inside and extends from the second pivot point F towards a more outer end of the internal body 7 at the portion next to the point D of connection to the rod 4 in such a way as to confer an asymmetrical profile on a part of the internal body 7.
- the remaining sides of the internal body 7 are completely straight.
- the internal body 7 has, without interruption, the first, end portion 7a tapered and extending towards the outside of the internal body 7, at the point D of connection to the rod 4, a second, straight intermediate portion 7b, at the above-mentioned second pivot point F, and a third, end portion 7c which is tapered and again extends towards the outside of the internal body 7.
- This internal body 7 external profile architecture allows not just slowing of the stroke and locking at the preset angle, but also slide 6 realignment (see Figure 7) relative to the second channel 8 when the mobile frame 2 moves from the open position to the closed position.
- Figure 5 shows by way of example and without limiting the scope of the present invention, the tapered third, end portion 7c with an extension R1 shorter than the extension of the first tapered end portion 7a.
- the second, straight intermediate portion 7b also has a transversal dimension T2 which is less than the transversal dimension T1 of the second channel 8.
- the drive unit structured in this way functions as follows, starting with a closed frame configuration.
- Mobile frame 2 opening causes the rod 4 to push the slide 6 (see arrow F3 in Figure 6), and is designed to allow the slide 6 to rotate or rock about the pivot point F in the second channel 8 (see arrow F1).
- the rotation is accentuated by the fact that the pivot point F and the point D of connection to the rod 4 are distanced, that is to say, offset from one another.
- this angled position of the internal body 7 of the slide 6 in the second channel 8 slows the mobile frame 2 descent, partly thanks to the friction generated both by the angled position and by the type of material used to make the body 7 (normally, but without limiting the scope of the present invention, a synthetic plastic material).
- the rod 4 maximum extension together with the maximum angle reached by the internal body 7 in the second channel 8 stops the opening movement of the mobile frame 2 when it reaches the angle ⁇ .
- a unit structured in this way fulfils the preset aims thanks to an extremely simple configuration of the elements, which is rational in construction terms and does not require any additional end of stroke elements in the mobile frame.
- the special shape of the slide internal body allows an extremely precise control of the frame movement, that is to say, substantially automatic slowing of the mobile frame descent and, in contrast, allows rapid upward sliding during the closing stage without any special adjustments on the slide.
Abstract
Description
- The present invention relates to a drive unit for bottom-hung or tilt and turn window frames, in particular for metal frames.
- At present, the above-mentioned bottom-hung window frames comprise a mobile frame hinged to the lower crosspiece of a fixed frame and a control unit for opening and closing the mobile frame.
- Between the fixed and mobile frames there are also means for guiding and for the stable positioning of the mobile frame, designed to allow the correct movement of the mobile frame between the closed and open positions, that is to say, at a preset angle to the fixed frame.
- Said means comprise one or two tie rods (according to the size of the frame), each pivoting at a first end in a channel in the section forming an upright of the fixed frame (by means of a suitably shaped rotary tie rod connecting pin), and at the other end at a slide which is slidably connected in a channel in a corresponding upright of the mobile frame.
- Therefore, the tie rod follows the opening and closing movement of the mobile frame thanks to the rotation allowed by the first fixed pivot on the fixed frame and by the sliding action of the slide along the channel in the mobile frame, thanks to the second pivot point.
- The maximum opening angle possible for the mobile frame is normally given by an end of stroke block fixed in the channel in the mobile frame, which stops the above-mentioned slide during mobile frame opening.
- Another structural addition of these guide and positioning means consists of means for releasing the slide or rotation pin so as to achieve complete rotation of the mobile frame, to allow the glass on the outside of the mobile frame to be cleaned.
- Means for guiding of the kind above described are known from document WO-A-0049258 which discloses an arm for casement window wings comprising securing means to a frame and securing means to a wing cooperating with means for limiting wing opening.
- The securing means to the wing are composed of a connection device that is slidable along the wing.
- The device is further equipped with locking and unlocking means that are commonly composed of a wire spring adapted to be housed into the device.
- However, with a frame structured in this way it is impossible to correctly control the mobile frame opening speed, that is to say, the sliding action of the slide in the channel in the mobile frame, with consequent continuous stresses on all of the parts of which the frame consists. Over time, this can all lead to movement of the end of stroke block in the channel and the breakage of drive elements.
- In an attempt to overcome such disadvantages, some devices have been developed which involve the use of screw means acting directly on the slide and designed to allow expansion of the slide transversal dimension, so as to achieve greater friction during mobile frame sliding.
- This device allows, on one hand, a more controlled frame descent, but on the other hand it makes it more difficult for the user to close the frame, since the resistance of the slide is equal in both sliding directions. In addition, it must be remembered that such solutions require frequent adjustments.
- The aim of the present invention is, therefore, to overcome the above-mentioned disadvantages by providing a drive unit for bottom-hung windows which has an extremely simple structure and with the possibility of gradual control of both the mobile frame descent and the mobile frame ascent and closing without the addition of any structural elements compared to conventional drive units.
- Accordingly, the present invention provides a drive unit for bottom-hung windows according to one or more of the appended claims.
- The technical features of the present invention, in accordance with the above-mentioned aims, are set out in the claims herein and the advantages more clearly illustrated in the detailed description which follows, with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention without limiting the scope of the inventive concept, and in which:
- Figure 1 is a perspective view with some parts cut away to better illustrate others, of a part of a bottom-hung window frame fitted with a drive unit according to the present invention;
- Figure 2 is a view from A in Figure 1 of a detail of the drive unit illustrated in Figure 1;
- Figure 3 is a view from B in Figure 1 of another detail of the drive unit illustrated in Figure 1;
- Figure 4 is an exploded perspective view of the drive unit illustrated in the previous figures;
- Figure 5 is a longitudinal section, with some parts cut away to better illustrate others, of a detail showing a slide of the drive unit, illustrated in the previous figures;
- Figures 6 and 7 are schematic front views with some parts cut away to better illustrate others of two different configurations of the slide illustrated in Figure 5 applied to a mobile frame;
- Figure 8 is a top plan view with some parts cut away to better illustrate others, of an alternative embodiment of the slide illustrated in the previous figures;
- Figure 9 is a longitudinal section with some parts cut away to better illustrate others, of the slide illustrated in Figure 8;
- Figure 10 is a cross-section through line X - X shown in Figure 8.
- With reference to the accompanying drawings, and in particular with reference to Figure 1, the drive unit in question is used for bottom-hung window frames.
- These bottom-hung frames, labelled 101, comprise a
fixed frame 1 to whosecrosspiece 1a amobile frame 2 is hinged at Y, the mobile frame moving between a closed position (not illustrated), in which it makes contact with thefixed frame 1, and an open position, in which it is set at an angle α to the fixed frame 1 (see Figure 1). - These movements by the
mobile frame 2 are made possible by actuating means which are not illustrated, being of the known type and not strictly part of the present invention. - Between the
fixed frame 1 and themobile frame 2 there are alsodrive means 3 which move themobile frame 2 from the closed position to the open position and vice versa. - As illustrated in Figures 2, 3 and 4, the drive means 3 may comprise (in a minimum configuration for small window frames) at least one
rod 4, its first end pivoting in afirst channel 5 of an upright 1b of thefixed frame 1 and the second end pivoting at aslide 6 which slides, by means of a suitably shapedinternal body 7, in asecond channel 8 of an upright 2a of themobile frame 2. - These window frames normally include two units consisting of the above-mentioned elements and positioned on the two uprights of the
fixed frame 1 and themobile frame 2. - As is clearly illustrated in Figure 5, at least one
end portion 7a of theinternal body 7 of theslide 6 at the point D of connection with therod 4, has a transversal dimension T which is less than the transversal dimension T1 of thesecond channel 8. In this way, theslide 6 rocks inside the second channel 8 (see arrow F1 in Figure 6). - This rocking allows the control, that is to say slowing, of the
mobile frame 2 stroke as it moves from the closed position to the open position. - To allow this type of controlled movement, the
slide 6 also comprisesmeans 9 which lock theslide 6 in and release it from thesecond channel 8, clearly illustrated in Figure 4. Said locking and release means 9 are used to allow themobile frame 2 to rotate through 180° to allow total cleaning of the external part of themobile frame 2. - In practice, the locking means 9 form a second pivot point F on the
slide 6, offset relative to the point D of connection to therod 4, and about which theslide 6 rocks. - In Figure 4 the locking means 9 comprise a
pin 10 attached to theslide 6. Thepin 10 has twoopposite projections manual grip element 10c, between a position in which theslide 6 is locked, in which theprojections slide 6 and are engaged in thesecond channel 8, and a position in which theslide 6 is released, turned through an angle E relative to the first position, in which theprojections slide 6, allowing its release from thesecond channel 8. - As is also illustrated in Figures 8 and 10, the above-mentioned
manual grip element 10c (illustrated with a dashed line) is partially housed in a lowered non-operating position, in aslot 100 in a surface of theslide 6, so as to stabilise thegrip element 10c (consisting of a spring) and prevent its unwanted rotation. - Looking more closely at the technical details, the
internal body 7 also forms amobile frame 2 end of stroke element, upon reaching the angle α, at a position in which it is at the maximum angle to the second channel 8 (again see Figure 6) and allowed by a stable contact of two opposite end points of theinternal body 7 on thesecond channel 8. - The rocking of the whole
internal body 7 is caused by its particular configuration, with a taper extending towards the outer edge of theinternal body 7, at theportion 7a next to the point D of connection to therod 4. - As illustrated in Figure 9, the
internal body 7 has aportion 7h of one of its sides that is at an angle β to the inside and extends from the second pivot point F towards a more outer end of theinternal body 7 at the portion next to the point D of connection to therod 4 in such a way as to confer an asymmetrical profile on a part of theinternal body 7. The remaining sides of theinternal body 7 are completely straight. - In an alternative embodiment illustrated in Figure 5, the
internal body 7 has, without interruption, the first,end portion 7a tapered and extending towards the outside of theinternal body 7, at the point D of connection to therod 4, a second, straightintermediate portion 7b, at the above-mentioned second pivot point F, and a third,end portion 7c which is tapered and again extends towards the outside of theinternal body 7. Thisinternal body 7 external profile architecture allows not just slowing of the stroke and locking at the preset angle, but also slide 6 realignment (see Figure 7) relative to thesecond channel 8 when themobile frame 2 moves from the open position to the closed position. - Figure 5 shows by way of example and without limiting the scope of the present invention, the tapered third,
end portion 7c with an extension R1 shorter than the extension of the firsttapered end portion 7a. - The second, straight
intermediate portion 7b also has a transversal dimension T2 which is less than the transversal dimension T1 of thesecond channel 8. - The drive unit structured in this way functions as follows, starting with a closed frame configuration.
-
Mobile frame 2 opening causes therod 4 to push the slide 6 (see arrow F3 in Figure 6), and is designed to allow theslide 6 to rotate or rock about the pivot point F in the second channel 8 (see arrow F1). The rotation is accentuated by the fact that the pivot point F and the point D of connection to therod 4 are distanced, that is to say, offset from one another. - During the
slide 6 upstroke (see arrow F4), this angled position of theinternal body 7 of theslide 6 in thesecond channel 8 slows themobile frame 2 descent, partly thanks to the friction generated both by the angled position and by the type of material used to make the body 7 (normally, but without limiting the scope of the present invention, a synthetic plastic material). - The
rod 4 maximum extension, together with the maximum angle reached by theinternal body 7 in thesecond channel 8 stops the opening movement of themobile frame 2 when it reaches the angle α. - During
mobile frame 2 closing, the upward thrust applied by the user is discharged mostly at the pivot point F (see arrow F5 in Figure 7), since therod 4 is, in this case, a passive closing element and allows a simple realignment counter-thrust (see arrow F6). This situation results in a counter-rotation of the body 7 (see arrow F7) until thebody 7 is substantially realigned with thesecond channel 8, with consequent rapid downward sliding (see arrow F8) by the body and rapid closing of themobile frame 2. - A unit structured in this way fulfils the preset aims thanks to an extremely simple configuration of the elements, which is rational in construction terms and does not require any additional end of stroke elements in the mobile frame.
- The special shape of the slide internal body allows an extremely precise control of the frame movement, that is to say, substantially automatic slowing of the mobile frame descent and, in contrast, allows rapid upward sliding during the closing stage without any special adjustments on the slide.
