L/T TLE 1 up COUNTERBALANCE MECHANISM SUMMARY OF THE INVENTION The present invention is generally directed towards a mechanism for counter balancing the torque effects of gravity on vertically swinging cabinet lids. More specifically, the mechanism includes a stationary hinge part adapted to be fixed to a cabinet; a movable hinge part mounted on the stationary hinge part for pivotal movement about an essentially horizontally disposed first axis; a compression spring; and an assembly for coupling the spring to the hinge parts to establish a moment tending to counter balance gravity induced torque effects on a cabinet lid with which the movable hinge part is connected for conjunctive vertical swinging movements. The assembly includes a connector having a bore opening; a hinge pin for supporting the connector on the stationary hinge part for relative movement about an axis disposed essentially normal to the bore opening and parallel to the first axis; a constraining member carried for vertical tilting movements relative to the movable hinge part; a bolt having one end extending freely through the constraining member and having another end rotatably supported within the bore opening; and a plate threadedly carried by the bolt adjacent the connector, whereby to permit adjustments of the plate lengthwise of the bolt. The spring is in the form of a coil type compression spring arranged essentially concentrically of the bolt to bear adjacent its opposite ends on the plate and constraining member, such that displacements of the plate effect the degree to which the spring is compressed. Thelid to be counter balanced may be carried directly on the movable hinge part. Alternatively, the lid may be independently hinge connected to the cabinet and movably coupled to the movable hinge part.
In accordance with a preferred embodiment, the connector is formed with aguide extension, which is arranged essentially parallel to the rod for sliding engagement with the plate, thereby to permit displacements of the plate to be effected by rotations of the bolt. A preferred construction would additionally feature the provision of a friction brake shoe, which is arranged for frictional engagement with the rod; the brake shoe dampening movements of the movable hinge part as a function of spring compression variations of the spring incident to movable hinge positional changes.
' DRAWINGS The nature and mode of the present invention will now be more fully described in the following detailed description taken withthe accompanying drawings wherein: R
FIG. 1 is a top plan view illustrating the mechanism of the present invention employed as a combination lid hinge and counter balance support;
FIG. 2 is a sectional view taken generally along line 2-2 in FIG. 1, but with lids attached;
.FIG. 3 is a view taken generally along line 3--3 in FIG. 1; and
FIG. 4 is a sectional view taken generally along line 4-4 in FIG. 2.
DETAILED DESCRIPTION Reference is now made particularly to FIGS. 1 and 2, wherein the mechanism of the present invention is generally designated as l l). Mechanism includes a stationary or base hinge part 12, which is to be suitably fixed to a cabinet-,not shown; a movable hinge part 14 for supporting a cabinet opening covering lid 16; a counter balance and motion snubbing assembly 18; and a hinge pin 20 for supporting hinge part 14 on hinge part 12, whereby lid 16 is supported for vertical swinging movements from an essentially horizontally disposed lid closed position into an essentially vertically disposed lid opened position. If desired, a second movable hinge part 22 may also be mounted on hinge pin 20 for the purpose of independently supporting a second or rear service cabinet opening covering lid 24. However, the presence of hinge part 22 or lid 24 is not necessarily a part of the present construction. Also, for any given installation, one or more of mechanisms 10 may be employed, depending on the weight and/or dimensions of lid 16.
As will be apparent from viewing FIGS. 1 and 2, the upper end of stationary hinge part 12 is bifurcated in construction, thereby to define parallel side flange members 26 to which are joined parallel inset side flange members 26'; members 26 being formed with aligned bearing openings for receiving opposite ends of hinge pin 20 and member 26' being formed with aligned bearing openings for receiving opposite ends of a second hinge pin 30. Moreover, rearwardly facing surfaces of flange members 26 are shaped to define shoulder abutments or stops 32, only one being shown in FIG. 2.
Opposite ends of mounting plate 60 are formed with dimpled ears 62, only one being shown in FIG. 3, which extend outwardly through cutouts 40 for receipt in notches 40a, thereby to support and constrain the forward end of assembly 18 on leg flange portions 38 for relative vertical pivoting or tilting movements. As will be apparent from viewing FIG. 2, bolt 46 passes freely through member 56 and mounting plate opening 58, and thus is free to reciprocate, tilt and undergo rotary adjustment movements relative to hinge part 14. If desired, plate 60 may be formed as an integral part of hinge part 14 and the bolt freed for tilting movements relative thereto by permitting member 56 to tilt within opening 58. Also, a suitable hinge pin arrangement may be employed to pivotally support plate 60.
The rear end portion of bolt 46 is rotatably received with a bore opening 64 formed in a connector 66; the latter being mounted for pivotal movement by second hinge pin 30 thereby serving to constrain assembly 18 relative to hinge part 12. Connector 66 is fonned with a guide extension or finger 68 arranged to extend codirectionally with bore opening 64. Spring plate 50 is formed with a top edge opening slot 70, which is dimensioned to slideably receive guide extension 68. This construction is preferred in that it permits rotations of bolt 46 to produce reciprocating movements of plate 50 lengthwise of the bolt for thepurpose of adjustably varying the extent to which spring 42 is initially compressed, whereby permitting adjustments of the counterbalancing effect of the mechanism on lid 16. Alternatively, if space considerations permit the insertion of a tool, not shown, for the purpose of constraining rotations of plate 50, guide extension 68 may be dispensed with. Also, if desired, the components of assembly 18 may be reversed, such that connector 66 is through bored to slideably receive rod 46 and plate 60 serves as an end bearing for the rod.
When lid 16 is in its closed position illustrated in full line in FIG. 2, spring 42 is subject to maximum compression, as determined by prior adjustments of spring plate 50; the spring establishing a moment tending to pivot the lid into open position.
The snubbing action," which is produced by frictional engagement of shoe 54 with rod 46 always opposes movement of lid 16, and thus alternately acts in opposition to and in conjunction with spring 42 during opening and closing movements of the lid, respectively. Thus, the snubbing action cooperates with the spring to define a counter balance envelope for the lid. When the gravity produced torque curve of lid 16 falls within its envelope, the lid is balanced" and prevented from coasting towards either of its open or closed positions. However, when for instance a portion of the torque curve of the lid is disposed about its envelope, as is preferred during the last to of lid closing movement, the lid is not balanced" and gravity is permitted to force same into a tightly closed position.
In the preferred construction, the moment of spring 42 acting alone is preferably matched as close as possible to the gravity produced torque curve of the lid, and
the snubbing" action of the brake shoe employed to compensate for any counter balancing deficiencies in the patterning of the spring moment as well as to prevent coasting of the lid. However, when the spring moment can be properly matched ,with the lid torque curve and/or coasting of the lid is not objectionable, the brake shoe may be eliminated.
