Description

FRAME SWINGING ON TWO DIRECTIONS ORTHOGONAL TO EACH OTHER, IN PARTICULAR

OF THE WINDOW FRAME TYPE"

The invention relates to a frame, particularly a window, which is swinging on two directions orthogonal to

each other, and can be regulated on different opening positions thereof, in either one of these two orthogonal

directions.

At the present time, the swinging frames like windows and the like are made in such a manner that to be able

to swing on a single direction, generally with horizontal or vertical extension, and are associated with suitable

control mechanisms which permit the displacement onto different regulating positions thereof.

The so structured frames, therefore, can swing around the single installation direction only and, thus, cannot

be able to be swung on another direction with different extension, so that in the case in which the opening of

the same frames on directions different than the installation direction is requested, it would be needed to use

further frames designed specifically for performing such functions.

The scope of the invention is to overcome the applicative limits of the present frames, by means of a

swinging frame of a new and different kind, of versatile type, which is able to swing on two different

directions, orthogonal to each other, with simple and quick manoeuvres, and adapted to permit the same

frame to be opened alternately in either one of these two directions.

This swinging frame is made with the constructive characteristics substantially described, with particular

reference to the attached claims of the present patent.

In the above mentioned Figures it is represented schematically a swinging frame 5 according to tlie invention,

particularly a window, door or the like, adapted to be displaced on different regulating positions and

specifically on a closed position (see Fig. 1), a ventilation position (see Fig. 2), a position swung around a

horizontal axis of rotation (see Fig. 3), and a position swung around a vertical axis of rotation (see Fig. 4), in

the ways and with the functions hereinafter described.

As visible from the Figures 1-4 and also from Figures 5, 6 and 8, such swinging frame is substantially

constituted by an inner framework 6 of quadrangular form, made of wood, metal, plastic or other suitable

material, which encloses all the peripheral edges of at least a plate 7 made of glass or other suitable

transparent material, which is so dimensioned as to be accomodated in a correspondent opening of

inhabitable buildings, and is also constituted by an outer stationary case 8 made with materials of the same

kind, and of tlie same quadrangular form, having sizes slightly larger than those of tlie framework 6, and

which is accomodated and fixed along the opening peripheral edges, and fixed at the lower side thereof with

the horizontal window sill 9 covering the lower horizontal edge of the opening, said framework being

alsoconstiruted by a movable section 10, interposed and housed between the inner framework 6 and the outer

case 8 and extended along all the peripheral edges of both the framework and the case.

Now, with reference to Figs. 5 and 8, in which the inner framework 6 is illustrated, and to Fig. 6 in which

also the outer case 8 enclosing such inner framework is illustrated, it is noted that the inner framework 6 is

shaped with rounded edges both on the longitudinal and transversal directions thereof and for the entire

lenght of its peripheral edges it accomodates some peripheral sealing gaskets made of elastomeric material,

in the present example formed by two gaskets 11 and 13, co-operating with tlie opposite peripheral edge of

the movable section 10 as it will be described,so as to ensure an outwardly sealing on the closing position of

the frame. Moreover, tlie inner framework 6 is provided with articulated support elements adapted to

effectively support such a framework and to keep it on a balance condition when it is displaced on one of its operative positions, swung around a horizontal axis of rotation (see Fig. 3) and a vertical axis of rotation (see

Figs. 4 and 5, this latter showing the upper part of the inner framework 6), by performing also the function to

limit the frame opening, in that such support elements allow the same frame to be opened on different

regulating positions thereof, in the manners which will be described.

To this aim, in the example shown on Fig. 3 the support elements are constituted by two extended arms (the

Figure shows the single arm 15), pivoted at the one end portion thereof along tlie upper center line of the side

edges 16 and 17 of the inner framework 6, and at the other end portion thereof on the upper part of the

opposite side edges of the outer case 8, so that such arms are extended outwards both the movable section

and the outer case, as visible from such Figure, when the inner framework is displaced outwards, and are

folded when said inner framework is housed internally and coplanarly to both said movable section and outer

case.Under these conditions, therefore, such support arms can be displaced on different regulating positions

extended outwards, thereby acting as opening limiting devices for the frame.

In the example shown in Fig. 4, the support arms 15 are pivoted at tlie one end portion thereof along the

upper horizontal edge 18 of the inner framework, on a position equally spaced with respect to the center line

of the same edge, and at the other end portion thereof along tlie opposite upper edge of the outer case 8, by

performing the same functions of the arms previously described.

Obviously, the articulated support arms can be applied also on other positions on the frame, provided that

they permit to perform always the same functions of the arms referred to, thus without departing from the

protection sphere of the present invention. In turn, tlie outer case 8 is constituted by a set of box-like sections,

formed by two horizontal sections 19 and 20 extended externally and parallelly spaced with respect to the

opposite horizontal edges 18 and 21 of the inner framework 6, and two vertical sections 22 and 23 joined

integrally or with a fixed joint to tlie previous sections and extended externally and parallelly spaced with

respect to the opposite vertical edges 24 and 25 of said inner framework, wherein all the sections are shaped

with a transversal profile of quadrangular form (see also Figs. 34-38), forming a continuous inner cavity 26

for housing the component parts which will be described, onto which a closing wall 27 is applied removably after that these component parts have been inserted in the same inner cavity, and also forming two side

projected portions 28 and 29 situated on a position opposite to such closing wall 27 and cooperating with the

opposite movable section 10 as it will be described.

The vertical sections 22 and 23 and the upper horizontal section 19 are enclosed with their corresponding

closing walls 27 into corresponding further sections 30, 31 and 32 made of wood, plastic or other suitable

material, which are joined at the lower side thereof with said horizontal window sill 9 and secured in the

opening of the inhabitable buildings, so that the side projected portions 28 and 29 of the same sections are

turned toward the adjacent movable section 10, for the grounds which will be described later.

Turning now to Figs. 1-4, 6 and 34-38 in which tlie intermediate movable section 10 is shown, which is made

of plastic material, metal or other suitable rigid material, it is noted that it is formed by two horizontal

sections 33 and 34 extended internally and paraUelly to the opposite horizontal sections 19 and 20 of the

outer case 8, and two vertical sections 35 and 36 joined with the horizontal sections 33 and 34 through

respective angular squares 37, 38, 39 and 40 and extended internally and parallelly to the opposite vertical

sections 22 and 23 of said outer case. All the sections 33, 34, 35 and 36 are shaped with a transversal profile

formed by two side edges 37' and 38' parallel to each other and enclosing the projected portions 28 and 29 of

the corresponding box-like sections of the outer case 8, with the interposition of corresponding sealing

gaskets 39' and 40' supported by the same sections 33-36, said side edges being joined with a hollowed front

portion 41 so shaped as to be adapted against the opposite horizontal peripheral edges 18 and 21 and vertical

peripheral edges 24 and 25 of the inner framework 6, and constituted by two narrow plane portions 42 and 43

adapted to bear against tlie respective sealing gaskets 11 and 13 housed in the same inner framework, and a

hollowed central and plane portion 44 joined to the plane portions 42 and 43 and so dimensioned as to be

adapted in the space comprised between said projected portions 28 and 29.

Thanks to this arrangement, all tlie sections 33, 34, 35 and 36 of the movable section 10 can be therefore

displaced at the same time, in tlie way which will be described, from a position fully reentering the

corresponding sections of the case 8 (see Fig. 36), in which they are moved away from tlie inner framework 6, to a position fully extracted from the sections of said outer case (see Figs. 34, 35 and 38), in which they are

approached to the inner framework 6 and the plane portions 42 and 43 are compressed tightly against the

associated gaskets 11 and 13 of said inner framework, by passing through an intermediate position (see Fig.

37) in which such sections are moved away from the inner framework of an extent less than the preceding

position, wherein the displacement of the sections 33-36 occurs while keeping the gaskets 39' and 40' of

these sections always into sliding contact with the opposite projected portions 28 and 29 of tlie relative

sections of the outer case 8, thereby ensuring always a tight sealing between these parts.

Referring now to the Figs. 8-11 and 20-22, there are discussed the two driving mechanisms of the frame

according to the invention, which are separated and overlapped to each other and housed in the continuous

inner cavity 26 of the different box-like sections 19, 20, 22 and 23 of the outer case 8, and substantially

comprise a first driving mechanism 45 associated with a handle 46, which in the example is articulated on the

vertical section 23 of said outer case, and adapted to cause the window or door to be pivoted around either a

horizontal or a vertical axis of rotation, and a second driving mechanism 47 associated with a handle 48,

which in the example is articulated on the vertical section 22 of said outer case, and adapted to cause the

window or door to be closed or opened in the ventilation position thereof, said first and second mechanisms

being operable independently from each other and constituted respectively by horizontal lenghtened tubes 49,

50 and 51, 52 parallel to each other and by vertical lenghtened tubes 53, 54 and 55, 56 joined with the

corresponding horizontal tubes by flexible metallic ribbons 57, 58 and 59, 60, said horizontal and vertical

lenghtened tubes being supported around the inner framework 6, on a position moved away therefrom, and

provided with the component parts which will be described, in order to provide for operating the same

mechanisms in the manners and with the functions hereinafter described.

Besides, the lenghtened tubes of each driving mechanism are joined reciprocally by means of at least a

corresponding spring 61 and 62, provided for the compensation of the clearances and ensuring always a

correct operation of the same mechanism, and applied on one of the same tubes, in the example shown respectively on the vertical tube 53, which is subdivided in two tube half-portions 63 and 64 (see Fig. 9), and

on the vertical tube 56 which is subdivided in two tube half-portions 65 and 66 (see Figs. 20, 21 and 22).

In the Fig. 33 it is shown the constructive item of the assembling of one of the springs to the relative

lenghtened tube, for example of the spring 61, in which it is noted that the end portions of such spring are

secured to the end portions of the tube half-portions (for example the half-portions 63 and 64) by means of

screws 67 or any other suitable per se known means.

The first driving mechanism 45, as visible from Figs. 8-11, is also provided with a first and a second pah of

set of pins 67 and 68 for articulating the window or door, which are provided respectively for pivoting such

window or door around either a horizontal axis of rotation or a vertical axis of rotation, wherein each set of

pin (see Figs.12 and 13 in which such set is represented respectively on a disassembled and assembled

condition thereof), is made with a set of separated parts made of plastic material substantially constituted by a

fixed block 69, a shaped plate 70 situated below said fixeti block and co-operating therewith, and an

additional plate 71 for supporting the preceding parts.

The fixed block 69 is made of box-like form and with limited thickness and is shaped with a central through

hole72 of circular form, joined with a projected head 73 coaxial thereto and having a frasto-conical form, in

which a corresponding cylindrical rectilinear shank 74 acting as a stud and shaped with a cylindrical body 75

is housed, wherein said cylindrical body is provided with a transversal through hole 76 and a tapered end

head 77 having frusto-conical form, in a way that such rectilinear shank can slide into the corresponding

through hole of the fixed block from a re-entering rest position thereof, in wliich it is completely housed into

said through hole and its tapered end head is flushing with the outer edge of the projected head 73 of the

same fixed block, to an extracted operating position thereof in which it is partially extracted from said

through hole and its tapered end head is projected beyond such outer edge.

Moreover, the fixed block 69 is shaped with a hollowed central slot 78 extended orthogonally to the central

through hole 72 for the entire thickness of the same block, in which a short rectilinear pin 79 is inserted, wliich is inserted also through the corresponding through hole 76 of the cylindrical rectilinear shank 74, in a

manner that such pin 79 is guided at its one end portion along tlie central slot 78, thereby being able to slide

reciprocatingly therein together with said rectilinear shank, and is co-operating at its other end portion with

the shaped plate 70 in tlie manner and for the function hereinafter described.

Finally, such fixed block is shaped with further through holes 80 and 81 laterally and parallelly to the central

through hole 72, for the insertion of corresponding screws, bolts or the like 82 therein for fixing the same

block to tlie masonry, while in turn tlie support plate 71 is inserted and fixed adequately in a corresponding

side and central recess 83 of the relative section of tlie inner framework 6.

The shaped plate 70 is made of parallelepiped form and reduced thickness and, as already explained, is

arranged on tlie corresponding section of the outer case 8 at a position below the relative fixed block 69, and

is shaped with two side rectilinear slits 84 and 85, extended longitudinally and centrally on the same plate, in

which a corresponding guide projected head 86 and 87 made integral with the corresponding fixed block 69

is inserted, and such shaped plate is also fixed to the corresponding lenghtened tube in such a way that when

this latter is operated by the handle 46 in either one of the rectilinear sliding directions A or B as it will be

described, the shaped plate is sliding rectilinearly in the same sliding direction, until to become stopped when

said guide projected head comes into abutment with the opposite curved end portion 88 and 89 of the relative

rectilinear slits 84 and 85. Each shaped plate is also provided with a central slit 90, on a position inteiposed

between the two side slits 84 and 85, which is shaped with an inclined central portion 91 and two side

rectilinear portions 92 and 93 which are oriented on directions opposite from each other and joined with such

inclined central portion 91, and the end portion of the pin 79 is inserted into the central slit 90, so that such

pin is sliding reciprocatingly through the slit, with consequent displacement of the shank 74 in either one of

its extracted or retracted positions, when the shaped plate 70 is being slided in the sliding direction A or B.

In order to provide for the pivoting movement around the horizontal axis of rotation of the window or

door, the two sets of pins 67 are housed in the respective vertical sections 22 and 23 of the outer case 8, on a

position opposite to each other and the corresponding shaped plates 70 of such sets of pins are oriented with the respective central slits 90 in the same way, in order to provide for operating the corresponding pin shanks

contemporaneously in either the retracted or extracted positions thereof.

Furthermore, in order to provide for the pivoting movement around the vertical axis of rotation of window or

door, the two remaining sets of pins 68 are housed in the respective horizontal sections 19 and 20 of the outer

case 8, on a position opposite to each other and the corresponding support plates 70 of such sets of pins are

oriented with the respective central slits 90 in the same way, however on a direction opposite to that in which

the plates 70 of the previous sets of pins are oriented, in order to provide for operating the corresponding pin

shanks contemporaneously in either the extracted or retracted positions thereof, in which condition the pin

shanks of tlie previous sets of pins are displaced on the respectively opposite position thereof.

In this way, it is guaranted the safety that the frame is displaced on the respectively desired pivoting position

only.

In the Figs. 14-16 it is shown a pin shank 74 for the pivoting movement around a horizontal axis, displaced

on three different operative positions thereof, respectively the retracted position (see Fig. 14), in which tlie

pin 79 is housed oin one of the side slit portions of the central slit 90, the extracted position (see Fig. 16) in

which the pin 79 is housed in the other of the side slit portions of said central slit, and the inteπnediate

position (see Fig. 15) in which such pin is housed centrally on the inclined portion 91 of said slit.

Likewise, Figs. 17-19 show a pin shank 74 for tlie pivoting movement around a vertical axis, displaced on the

same operative positions previously described.

Finally, the support plate 71 of the first driving mechanism 45 is shaped with side through holes 94 and an

enlarged centtal hole 95, provided ttansversally to the same plate so as to permit coπesponding screws, bolts

96, 97 or the like to be inserted therein, these latter adapted to be fixed against the inner framework 6.

The central hole 95 accomodates a bush 99 for inserting the tapered head 77 of the relative rectilinear shank

74 therein, when this latter is displaced on its extracted operating position. In turn, the second driving mechanism 47, as visible in the Figs. 20-22, is also provided with four pairs of

locking stops 100 and 101, 102 and 103, 104 and 105, 106 and 107 for locking the window or door on the

closed position thereof, wherein each pair of locking stops (see Figs. 23 and 24 in which such stop

isrepresented respectively on the disassembled and assembled condition thereof) is realized with a set of

separated parts made of plastic material, substantially formed by a fixed block 69 and a shaped plate 70

situated above such fixed block and cooperating therewith, which are identical to the coπesponding

components previously described and differ therefrom for the constructive items which will be described

later.

All the locking stops are housed internally the box-like sections constituting the outer case 8, and are joined

with the coπesponding sections of the inteπnediate movable section 10, in such a way as to provide for the

displacement of such sections on their different operative positions as it will be described later.

As visible specifically from the above mentioned Figures 20-22, moreover, the stops of each pair are paired

from each other and positioned laterally to the coixesponding sets of pins, near the relative angular area of the

corresponding shaped sections, and in particular the pair of stops 100, 101 and 102, 103 are housed in the

respective vertical sections 22 and 23, while the pairs of stops 104, 105 and 106, 107 are housed in tlie

respective horizontal sections 19 and 20, and all the shaped plates 70 are secured to the coiresponding

lenghtened tube in a manner that when this latter is operated by the handle 48 in either one of the rectilinear

sliding directions C or D as it will be described, the shaped plate is slided rectilinearly in the same sliding

direction, up to stop it when one of the guide projected heads 86 and 87 comes into abutment with the

opposite end portion of either the rectilinear shts 84 or 85 of the coπesponding plate. Furthermore, all the

shaped plates 70 are oriented with the respective centtal slits 90 on tlie same manner, in order to be operated

contemporaneously all on the same operative position.

Finally, all the fixed blocks 69 of the second driving mechanism 47 are different from the block previously

described in that they are provided with cylindrical rectilinear shanks 108 shorter than the preceding ones,

which are sliding in the corresponding through hole of the related fixed block and adequately joined with then end head 108 'with the relative sections of the intermediate movable section 10, in such a way that the

displacement of the cylindrical shanks, obtained as previously described, provides for also the displacement

of such sections from the one to the other one of their reentering or extracted position, thereby displacing the

frame from the opening position thereof (see Fig. 36) in which these sections are reentering thecoπesponding

sections of the outer case 8 and fully moved away from the inner framework 6, in which condition the frame

is oriented around either a horizontal or a vertical axis of rotation, in the manners which will be described

later, to the closing position thereof (see Fig. 38) in which these sections are exttacted and hardly compressed

against the inner framework 6, in which condition the frame is locked on this position, and also by displacing

said frame even through tlie ventilation position thereof (see Fig. 37), which is intermediate between the

preceding positions, in which these sections are partially extracted and moved away from the inner

framework 6 of an extent less with respect to the opening position thereof, in wliich condition tlie frame is

supported contemporaneously by the horizontal pins and the vertical pins in the manners which will be

described.

In this way, it is guaranteed the safety that the frame is always displaced on the regulating position

respectively desired.

In the Figs. 25-27 is shown a rectilinear shank 108 displaced on the above mentioned three different

operative positions thereof, respectively the retracted position (see Fig. 25) in which the pin 79 is housed into

one of the side slit portions of tlie centtal slit 90 of the related shaped plate 70, so that the frame is displaced

on the opened position thereof, the exttacted position (see Fig. 27) in wliich the pin 79 is housed in tlie other

one of the side slit portions of said centtal slit, so that the frame is displaced on the closed position thereof,

and the partially extracted position (see Fig. 26) in which the pin 79 is housed centrally in tlie inclined

portion 91 of said central slit, so that the frame is displaced on tlie intermediate ventilation position thereof.

The Figs. 28-32 now illustrate in detail additional constructive characteristics of the frame according to the

present invention. In the Figs. 28 and 29, in particular, it is made evident one of the lower angular areas of the frame outer case

8, in which it is noted that for permitting the flexible metallic ribbons 57, 58 and 59, 60 of the two driving

mechanisms 45 and 47 of the same frame to slide, each angular area of the outer case 8 is provided with an

angular part 109 bent orthogonally and shaped with a pleated bent edge 110 and a smooth bent edge 111

which is opposite to and shghtiy spaced away from tlie preceding edge, thereby defining between them a

guiding path for sliding the coπesponding flexible ribbons therein, and also shaped for peπnitting the related

sections of said outer case to be applied thereon.

In this way, the presence of such pleated and smooth edges determines an effective and safe sliding of the

flexible ribbons on all the operative positions of the frame, while preventing any stop or incidental jamming

thereof and also permitting self-cleaning operations of the parts from any particles in suspension stored

thereon.

Besides, in the same Figures it is noted that tlie angular part 109 is provided for supporting also a plane

square 112, shaped with a wing 113 extended orthogonally therefrom, so as to be inserted in a coπesponding

through hole (not indicated) of said angular part, as well as shaped with two forks 114 and 115 parallel from

each other and extended orthogonally tiierefrom at the side opposite to that of the wing 113, and provided

with slits 116 and 117 for supporting the axis of rotation 118 of a wheel 119, turned toward the lower

horizontal edge 21 of the inner framework 6 and co-operating with a corresponding longitudinal slot 120

provided on the same lower edge.

In the Figs. 28 and 29, moreover, there are noted the support elements 121 of the frame glass plate 7, which

are adequately secured in tlie inner framework 6.

Also the remaining angular part 109 housed at the other lower angular area of tlie outer case 8 supports an

identical wheel 119 in the same way as described, in which circumstance such wheels are covered by the

movable section lOwhen it is displaced on its extracted position (see Fig. 38), in which tlie frame is closed,

and are uncovered when said movable section is displaced both on its partially exttacted position (sse Fig. 37), on the frame ventilation position, and its reentering position (see Fig. 36) in which the frame is displaced

on the opening position thereof and pivoted around either a horizontal or a vertical axis of rotation.

Therefore, on these two latter positions of the movable section 10, such wheels 119 perform a further

function of supporting the frame, while permitting the sliding thereof.

In the Fig. 32 it is shown tlie item of the articulation of a support arm 15 to the corresponding edges of the

inner framework 6 and the frame outer case 8, which in the example referred to is articulated at its end

portions respectively on a lenghtened stud 122 fixed to the relative angular parts 109 housed in the upper

angular areas of the outer case 8, and a further stud 123 slidable along the edge of the inner framework 6, and

provided with a regulating grub screw 124 for frictioning on a different extent the sliding movement of the

arms 15.

Turning now to the Figs. 11, 39-44, shown therein are the handle 46 and the different component parts

associated therewith, which act on the first driving mechanism 45 to provide for the pivoting movement of

tlie window or door around either a horizontal or a vertical axis of rotation thereof.

These component parts are constituted substantially by a rectilinear rack 125 fixed on a box-like block 126

which is housed in the outer case 8 on a position adjacent to and aligned with tlie coπesponding fixed block

69 of the first driving mechanism 45, and also joined with the lenghtened tube 54 of such driving mechanism,

said block being^' shaped for supporting at its upper side a support plate 127, shaped with a rectilinear guide

member 128 adapted on the same block, and an upper semi-circular portion 129, as well as are constituted by

a sector gear 130 of semicircular form, which adapts itself on the semi-circular portion 129 and is inserted at

its lower side into a vertical projected stud 131, provided integral with tlie block 126, with the interposition

of a spring 132 therebetween, in a way that the teeth of such sector gear 130 mesh tlie coπesponding teeth of

the rack 125, and is joined orthogonally with an upper lenghtened shank 133 onto which the handle 46 is

applied, with tlie interposition of a further spring 134. Therefore, with this arrangement the rotation of tlie

handle 46 on a determined dhection causes a consequent rotation of the section gear 130 in the same

dhection and a rectilinear shding of both the rack 125 and the block 126 in the opposite direction, along tlie section 23 of said outer case, and under these conditions the handlecan be rotated on the three different

operative positions thereof in wliich it causes the displacement of the pin shanks 74 respectively on the

vertical pivoting and locking position of the frame (see Figs. 4 and 1), the intermediate ventilation position of

the frame (see Fig. 2) and the horizontal pivoting position of the frame (see Fig. 3).

Besides, the box-like block 126 is provided with a set of front hollows aligned from each other, in the

exampleconstituted by the three hollows 135, 136 and 137 defining the sliding positions of the block 126

corresponding to the above mentioned three operative positions of the frame, and into which a short

rectilinear shank 138 of a fixing element 139 can penetrate selectively and orthogonally, which element is

provided with an enlarged circuhead 140 joined with the movable section 10, after having inserted such

shank through the through hole 141of an additional fixing element 142 joined with the section 23 of said

outer case.

In this way, depending on the displacement position of the movable section 10, there are displaced

contemporaneously on tlie same direction both tlie head 140 and the shank 138 joined thereto, from a position

in wliich such shank is extracted and disengaged with respect to the front hollow from time to time

coinciding therewith, when the movable section is displaced on its fully extracted position, in wliich

condition the handle 46 isn't locked by such shank and therefore ca be rotated in any operative position

thereof, to a position in which such shank is either partially or fully inserted and engaged with respect to said

front hollow, when the movable section is displaced respectively on its intermediate position partially

reentering or its fully reentering position, in which condition the handle 46 (see Figs. 41 and 42) is locked by

such shank and therefore cannot be rotated and must remain on the operative position on which it was

previously displaced.

Turning now to the Figs. 20 and 45-48, shown therein are the handle 48 and the different component parts

associated therewith and acting on the second driving mechanism 47, constituting a safety device against the

manoeuvre of the other handle 46 when the frame is displaced on its opening position, for any pivoting

condition thereof, or when it is displaced on the ventilation position thereof. These component parts are substantially identical to those ones of the preceding driving mechanism, and

therefore are marked with the same reference numerals, except for the fact that in this case the fixing

elements 139 and 142 have been eliminated and that the box-like block 126 is shaped frontally and centrally

with a naπow rectilinear through slot 143, which is joined laterally with two through openings 144 and 145

which are larger than the slot 143, so as to provide for tlie support of a safety element 146 formed by a short

rectilinear shank 147, adaptable slidingly in the through slot 143 and joined with a head 148 wliich is larger

than such shank and adaptable slidingly in either one of the through openings 144 or 145, but not adaptable

in the through slot 143, said safety element being also formed by a pierced ring nut 149 and a covering

conical cap 150 into which it is inserted in succession said shank, with the interposition of a spring 151

urging tlie same shank in the direction E directed outwards, and finally by an end ferrule 152 for closing the

cap 150, which is turned towards tlie inner framework 6 and co-operating therewith.

The scope of the safety element 146 is to prevent the rotation of both the handle 48 and the section gear 130,

and therefore the longitudinal sliding of the block 126, when the head 148 is housed in either one of the

through openings 144 or 145, and is kept on this position by means of the thrust of the spring 151, in wliich

condition tlie inner framework 6 is displaced on the opening position thereof pivoted around either a

horizontal or a vertical axis of rotation, or on the ventilation position thereof, and such inner framework does

not bear against said end ferrule 152.

Then, in this case the rotation of the handle 48 on any of its operative positions is permitted only when the

inner framework 6 is displaced on a position aligned with tl e outer case 8 and, therefore, by compressing

both the ferrule 152 and the shank 147 inwardly, against the action of the spring 151, it disengages the head

148 from the through opening in which it is inserted thereby peπnitting tlie shank 147 to slide through the

through slot 143.

The operation of the so obtained frame from the one to the other one operative positions thereof, by acting on

the first handle 46, can be effected only when the frame inner framework 6 is displaced on said aligned position thereof, in which condition such frame is always supported with safety, either by the movable

section 10 displaced on the locking position thereof (see Fig. 1), or by the pin shanks 74 extended for

forming either the horizontal axis of rotation (see Fig. 3) or the vertical axis of rotation (see Fig. 4), or both

the axes (see Fig. 2) on the ventilation position thereof.

In this way, when the handle 48 is rotated on its operative position in which tlie movable section 10 is fully

extracted (see Figs. 34, 35 and 38), therefore locking tlie frame on the closing position thereof, tlie remaining

handle 46 can be rotated in any other operative position thereof in that tlie shank 138 is disengaged from the

associated front hole of the box-like block 126.

As soon as such operative position of the handle 46 is attained, by maintaining the frame always locked on

the closing position thereof, and supported with safety by the pin shanks forming the horizontal, or tlie

vertical axis, or both the axes, the remaining handle 48 is rotated onto another operative position thereof in

which the movable section 10 is displaced on its partially or fully reentering position, in which condition the

shank 138 is either partially or fully inserted and engaged with respect to the relative front hollow of said

block 126, with consequent locking of the handle 46 on the new attained operative position thereof and

impossibility of a further rotation tiiereof and a displacement of tlie inner framework 6 of the same frame on

the intermediate position thereof pivoted around either a horizontal or a vertical axis of rotation or on the

intermediate ventilation position thereof.

In this case, the handle 46 can be released and therefore rotated on another operative position thereof, only

after having displaced the inner framework 6 on the aligned position thereof and rotated tlie remaining handle

48 on the other operative position thereof, in wliich such inner framework is locked on the closing position

thereof as described previously.

The so obtained frame is of versatile type and can be displaced with easy, simple and safe manoeuvres on its

different operative positions of closing, or of complete opening in which it is oriented around around either a

horizontal or a vertical axis of rotation, or also on a partially opened position for permitting the ambient ventilation, thereby eliminating the need to employ specific frames for performing the same functions, with

consequent less cost burdens.

Furthermore, thanks to the particular arrangement with fixed joints of the sections of the inner framework

and those ones of the movable section 10, it is possible to obtain effective tightly lockings along all the

perimeter of the same frame.
