Abstract
Description
- Vertically sliding door units are well known and widely used, particularly for wardrobes and furniture in general.
- In vertically sliding door systems currently in use, a sliding door is supported at one end of at least one cable, which is wound on one or more idle pulleys and is fixed, with its other end, to a counterweight of equal weight to that of the door.
- This system provides excellent balancing of the door in all its possible positions. A minus point is that the unit is very heavy and bulky and therefore unusable in many circumstances.
-
US 4,760,622 discloses a balancing mechanism for vertically sliding window sashes comprising biasing force transmission means (comprising a tackle assembly), a conical, spiral-grooved pulley whereon a cable connected to a spring is windable and a cable drum, aligned to the conical pulley and fixed thereto for rotation together, whereon a cable connected to the tackle assembly is windable. - An aim of the present application is to produce a vertical sliding door unit of reduced weight and bulk, compared to said traditional systems, so that it may be used in furnishing applications and achieve more widespread use.
- Such an aim has been achieved with a mechanism as contained in
claim 1. Additional new and desirable characteristics are said in the dependent claims. - In other words, the new mechanism includes, for each vertically sliding door, at least one return or balancing spring means, an idle door cable winding wheel between the door and the spring means, a length of a door cable secured by one end to the door, with the other end being attached to the door cable wheel, a length of a spring cable secured to the spring and a to a spring cable winding wheel, a winding groove of varying radius being provided on the spring cable winding wheel. There are two winding wheels, one for the door cable and the other for the spring cable, which are coupled by reduction gearing.
- The new unit may use helical spring or gas systems as the balancing means for vertically sliding doors and therefore proves more compact and lighter compared to traditional vertical sliding door units.
- The invention will be better described by referring to exemplary unrestrictive embodiments, shown in the annexed figures in which:
-
figure 1 is a broken-away elevational side view of a side unit of a vertical door movement mechanism, according to the invention, shown reduced; -
figure 2 is a cross-sectional view along plane 2-2 infigure 1 , shown enlarged with respect to said figure; -
figure 3 shows in an enlarged scale with respect to the previous figures, a spring tension regulation device, at the base of a spring; -
figure 4 shows a further embodiment of a side unit of a movement and balancing mechanism, in this case for a pair of opposite vertical sliding doors. - With reference first to
figures 1 ,2 and3 , a side unit for a movement and balancing mechanism for a vertical sliding door, carried on afixed structure 1, is denoted, as a whole, byreference number 10. The door is referenced 2 and is guided through its vertical movement on fixed guides, referenced 4, on which it slides by means of, e.g., bearings orrollers 5. One end of a length offlexible cable 12, hereafter referred to as door cable, is fixed to adoor bracket 6. Thiscable 12 winds round a stationary idle roller orpulley 14, onfixed structure 1, and is secured and winds round a peripheralgrooved wheel 16, which is idle on thefixed structure 1. The peripheral groove ofwheel 16 is referenced 18. As can be seen infigure 2 ,wheel 16 is idle supported on apivot 20, having its axis a20 integral tostructure 1, by abearing 22. A small diameter crown wheel or toothing 24 is integral to thegroove wheel 16 and meshes with a large diameter toothing 26 of a further wheel, or gear wheel, 28. The latter is supported idle, by abearing 30, on apivot 32, having axis a32, carried bystructure 1. The axes a20 and a32 are parallel, in the example in the figures.Wheel 28 has awinding groove 34 for a cable, which groove has a varying radius around axis a32, as can be seen, for instance, infigure 1 . - A second length of cable, or
spring cable 36, has one end secured ingroove 34, so as to wind round it, and the other end secured to areturn spring 38, shown in a broken-away view infigure 1 . Thereturn spring 38, in the example shown, is a helical spring secured, in an adjustable way, to a stationary anchorage instructure 1, as shown infigure 3 . The anchorage system of the spring could be any known anchorage system, for example, as infigure 3 , a system comprising acooperating screw 41 andnut screw 42, in which a lower end ofspring 38 is locked to the nut screw by apivot 43. - The system of the invention, through appropriate sizing of the
variable radius groove 34 depending onspring 38, is able to provide for perfect balancing ofdoor 2 in all positions thereof. The weight ofdoor 2, applied tocable 12, is vertical in the vertical section of thecable 12 and horizontal in the horizontal section of thecable 12. The following condition must be satisfied for balance ofwheel 16 around its axis a20: P.r16= T.r24
where P is the weight of the door (or of the door portion relating to side unit 10), r16 is the radius of the cable winding surface ofwheel 16, T is the force exchanged bywheels toothings wheel 28, the following condition must be satisfied: T. r26= F. r34
where F is the force exerted byspring 38, and r34 is the varying radius of the bottom of groove 34 (winding surface). Since the force exerted byspring 38 varies according to the drawing conditions of spring 38 (and is generally greater if the spring is extended), by properly designing the varying radius ofgroove 34, F. r34 can be made constant. This ensures perfect balancing ofdoor 2, at all moments and, in short, a smooth vertical door raising and lowering motion. - The mechanism has considerably reduced weight and limited bulk, with respect to a counterweight system, as could be seen for instance in
figure 2 , in which it can be appreciated that it may be enclosed in abox 50 of limited thickness. - A unit including the
cable 12, thewheels spring 38 may be centrally arranged with respect todoor 2, or two such symmetrical units could be provided for with identical characteristics and positioned at the sides ofdoor 2. - In
figure 4 , a modified embodiment of the unit is shown, for a pair of opposite vertically sliding doors. Infigure 4 a movement and balancing unit for theupper door 2 has the same references as forfigure 1 and will not be described in detail. In the lower part of the figure a further vertical door is shown and referenced 102. The details thereof and the movement and balancing unit thereof have the same references as for the upper door, increased by 100. In particular, therefore, adoor cable 112 is coupled todoor 102, by anarm 103, and winds round anidle snub pulley 114 and an additionalidle snub pulley 115. Thus it winds around anidle wheel 116 supported on thestationary frame 1, said wheel having aperipheral groove 118. An end of thecable 112 is secured in said peripheral groove. Thecable 112 is wound onwheel 116 is an opposite direction with respect tocable 12 on thewheel 16.Wheel 116 has an externallytoothed portion 124, of reduced radius, that engages with a toothing 126 of afurther wheel 128.Wheel 128 is idle round apivot 132 supported on theframe 1.Wheel 128 has avarying radius groove 134 in which one end of aspring cable 136 is secured, the other end thereof being secured to aspring 138. Thecam groove 134 has an identical but opposed configuration to that ofcam groove 34. - The considerations on the equilibrium of the wheels referring to
