Abstract
Description
- This invention relates to a device capable of causing a plurality of wing elements to open and close through combined swinging and sliding movements thereof, these wing elements being generally of the type as used in the furnishings art, for example, for constructing the front wall of a cabinet, a partition, etc..
- Opening and closing arrangements for wing elements of the type referred to above, which is usually supported at its top and guided at its bottom, are well known.
- The wings are commonly pair-arranged with the wings of each pair of wings being able to be opened like a "book", that is to say, to be superposed upon each other and then moved together to one side or the other.
- Accordingly, if a rather wide or almost complete opening of the aperture covered by the wings is to be obtained, it is necessary for all of the various pairs of wings to be individually opened like a book and then all of them translated to one side.
- US-A-3,344,837 describes a folding panel assembly according to the preamble of
claim 1, which may be used in an opening in a structure, in particular as a door for a garage, and which is movable vertically between an extended, lower position and a retracted or stacked upper position. - According to this arrangement, gear wheels and associated complex mechanisms are provided for moving together the panels, which, however, can be brought only to the upper end of the opening in the stacked position.
- It is an object of the present invention to avoid the disadavantages of the known arrangements, and to enable a plurality of wings to be opened simultaneously with the same angle of inclination, so that by action on one terminal wing all of the wings can be moved to an opposite side, upon opening of the wings, and vice versa upon closing thereof.
- The above object is attained according to the invention, by the features listed in the appended
claim 1. According to the claimed invention, a hinge device is arranged between the different wings in an alternate manner, the hinge device being able to convert the swinging movement of a wing into a swinging movement equal but opposed in direction of an adjacent wing, thereby to achieve sliding movement of all of the wings in a same direction. - Advantageously, this device includes a pair of gear wheels constantly in mesh with one another, supported, for example, by the guide and support head rail of the wings, these gear wheels having each an arm associated thereto, which arm is slidingly guided into a corresponding wing.
- These and further features of the invention will clearly appear from a reading of the detailed description given herein below in relation to one embodiment of the invention shown, by way of example only, in the accompanying drawing, in which:
- Figure 1 is a schematic horizontal sectional view of the front part of a cabinet having four wings;
- Figures 2 and 3 are views similar to Figure 1 and show successive steps in opening the four wings from right side to left side in a simultaneous manner;
- Figure 4 is a detail view of the device indicated by A in preceding figures which enables the various wings to be opened and closed in a simultaneous manner;
- Figure 5 is a schematic vertical sectional view of the device in Figure 4;
- Figure 5' is a similar sectional view to Figure 5 but showing a different arrangement of parts;
- Figure 6 is a sectional view taken along the line VI-VI in Figure 5 or 5';
- Figures 7, 8 and 9 show the same views as those in Figures 1, 2 and 3, respectively, but when relating to a cupboard having five wings;
- Figure 10 is a schematic plan view showing handling of a terminal wing in the arrangement of figures 7 to 9.
- Figures 1 to 3 are schematic views of the front part of a cabinet which is shown to have
vertical walls 1 with the inside space being closed at its front by an even number ofwings 2, in particular fourwings 2. - It is to be understood that the above example is merely an illustrative example and that the
wings 2 could both be different in number -for example 6 in number - and serve for a different purpose from that shown, for example, they may be used for constructing a partition. - As shown in figures 1 to 3, the
wings 2 are pair-arranged so that the wings in each pair of wings can be superposed upon one another through combined swinging and sliding movements thereof. Accordingly, the remote ends 2' of the wings of each pair of wings are supported and guided between two rails, namely a top and a bottom rail (not shown) as usually provided for enabling the wings to slide, while the adjacent ends of wings in each pair of wings are hinged to one another to permit the wings to open and close"as a book", in a conventional manner. - According to the invention, the ends 2' of adjacent pairs of wings are connected together, as at the encircled locations A in figures 1 to 3, by the aid of a hinge device shown in figures 4 and 5 or 5', which device enables all of the wings to be opened and closed simultaneously, in a manner to keep them parallel two by two, and to cause all of them to slidingly move to a side, by action upon one of the two terminal wings, as schematically shown figure 2 and 3.
- This hinge device, shown in figures 4 and 5 or 5', is generally indicated by
reference numeral 3 and substantially comprises a pair ofgear wheels 4 in constant mesh with one another, each gear wheel having integrally connected to it anarm 5 carrying a pair ofrollers 6 at the free end of the arm, therollers 6 being arranged to roll in an associated C-shaped guide member 7 (see figure 6, in particular) fastened to the inside of acorresponding wing 2. - As shown by way of example in vertical sectional view figure 5 - where the left and right half parts of the hinge device are seen in complete sectional view and partly sectional view, respectively - the two
gear wheels 4 are mounted for free rotation on respectivevertical pins 8, supported by abody 9, whichbody 9 has associatedstirrups 11 fastened byscrews 10 to both sides ofbody 9, saidstirrups 11 having hinge means 12 provided thereon for fixing and supportingcorresponding wings 2. - Arranged at the top of each
stirrup 11 are pairs ofrollers 13 of horizontal axis and pairs ofrollers 14 of vertical axis (only the rollers on left-side stirrup being shown in figure 5), these pairs of rollers being for the purpose of supporting and guiding a correpondingwing 2 in said upper guide, not shown. - The embodiment in figure 5' substantially differs from that in figure 5 by the
guides 7 being arranged in another way. The same reference numerals as those in figure 5 have been used in figure 5' to show equal parts. - From the above description, operation of the device according to the invention is readily apparent and is as follows.
- Referring to figures 1 to 3, when an outwardly and left-side directed pull is exerted on an appropriate handle (not shown) of an endmost wing that is placed to the right in said figures, this endmost wing and the wing adjacent thereto are caused to open "like a book". Rotation of this latter wing causes, through its associated
arm 5, rotation of thecorresponding gear wheel 4 which causes in turn the correspondingintermeshing gear wheel 4 to rotate in an opposite direction, thereby to produce an identical rotation of associated wing 2 (see in particular figures 2 and 3). Obviously, rotation ofwings 2 is combined with sliding movement ofsame wings 2 on their support guides. - Figure 4 schematically shows by dotted lines an open position of the righthand wing and the corresponding part of hinge device.
- In a similar manner, opening may be obtained by starting from the lefthand terminal wing.
- Figures 7, 8 and 9 schematically show successive opening steps when an odd number of wings, in particular five wings, are used.
- In this case, a further hinge device 3 (see figures 4 and 5 or 5') is provided between a terminal wing and a close adjacent wing, as evidenced by the encircled areas again indicated by reference letter A in figures 7, 8 and 9.
- The
terminal wing 2 whose outer end is free, is connected to a sliding rail, for example the upper rail, through astiff rod 15. - The
rod 15 is in particular hinged at its one end, in 16, to an intermediate location onwing 2 and at its other end to acarriage 17 which is arranged to slide on an appropriate rail. - In this manner, opening of the wings occurs in a similar manner to that described in relation to figures 1 and 3 and as schematized in figures 7 to 9, the
terminal wing 2 always moving parallel to corresponding wings placed in alternate positions in the set, due to the presence of thestiff rod 15. - In figure 10, the
terminal wing 2 is shown, by continuous line, to be in approximately full open position towards the left side (it is to be intended that in this condition the wing is translated in proximity to the left end of a cabinet) and,by dotted line, in both the closed position and the almost full open position towards the right side.
