Patent number: 5617612Abstract: A furniture hinge (10) comprises a first cup-shaped element (11) and a second arm-shaped element (12) pivoted together to rotate reciprocally from an open position to a closed position. The arm-shaped element (12) is made of sheet metal with one end (20) bent to wind round a hinge pin (21) supported in the cup (11). The bent end of the arm-shaped element (12) also defines bearing surfaces (22) for a double twist pressure spring (23) which pushes the first and second element towards the closed position starting from a position close to the latter. A U-bolt forms the hinge pin (21) and a pin (26) supporting the spring.Type: GrantFiled: December 20, 1994Date of Patent: April 8, 1997Assignee: Franco FerrariInventors: Franco Ferrari, Carlo Migli

Patent number: 5586364Abstract: A fastening element for fastening hardware elements (31) to parts of furniture units (14) comprises an expansion plug (11) having an axial through housing (17) which can receive an expanded pin (23), which can rotate between a position in which the plug is not expanded, to enable it to be inserted in a hole (16) in the furniture unit (14), and a position in which the plug is expanded to anchor it in the hole. The walls of the axial housing (17) and of the pin (23) have reciprocal contacting surfaces in the expanded position which diverge in the direction of insertion of the plug. A cam plate (32) provided centrally with a polygonal hole (33) for coupling with a protrusion (30) of the pin (23) and peripherally with a raised edge (34) for guiding fingers (22, 22') of the plug (11) for reversibly guiding the expansion of the plug.Type: GrantFiled: April 24, 1995Date of Patent: December 24, 1996Assignee: Franco FerrariInventors: Franco Ferrari, Carlo Migli

Patent number: 5535504Abstract: A machine for fitting metal runners on a drawer comprises an actuator (44) for mechanically operating at least one hammer (24) for clinching gripping tabs against a side panel (16) of the drawer. The gripping tabs are laterally disposed along a longitudinally extending U-shaped groove formed in the runner (12) and extending from a longitudinal edge of the runner towards the hammer, prior to clinching. The hammer (24) and the corresponding anvil counter plate (22) extend in a longitudinal direction to the runner to simultaneously clinch all the gripping tabs. Advantageously, the machine comprises two clinching assemblies (20) to clinch both runners to a drawer in a single operation.Type: GrantFiled: March 23, 1995Date of Patent: July 16, 1996Assignee: Franco FerrariInventors: Franco Ferrari, Carlo Migli

Patent number: 5514581Abstract: Novel polymers are provided which are produced by recombinant techniques. The polymers are characterized by having a small repeating sequence which provides for strands capable of associating, resulting in useful structural characteristics, where the strands are joined by turns or loops which are flexible and available for interaction with the environment. Specifically, repeating groups of naturally occurring proteins such as silk are modified by introduction of an amino-acid sequence at a site which provides for a turn between strands to provide for readily available oligopeptides capable of interacting with molecules in the environment.Type: GrantFiled: November 6, 1990Date of Patent: May 7, 1996Assignee: Protein Polymer Technologies, Inc.Inventors: Franco A. Ferrari, Joseph Cappello

Patent number: 5496712Abstract: Collagen-like polymers having repetitive triads are produced having reduced proline content, where glycine is the initial amino acid and the subsequent amino acids are varied, while retaining at least a minimum percentage of prolines. The resulting polymers have collagen-like properties, but are capable of being produced in unicellular microorganisms at high molecular weights and in high efficiency. The polymers while retaining collagen-like characteristics, include various novel sequences which impart new characteristics, finding wide use in photographic, medical, structural and fiber applications.Type: GrantFiled: November 5, 1992Date of Patent: March 5, 1996Assignee: Protein PolymerInventors: Joseph Cappello, Franco A.

Patent number: 5460443Abstract: A device (10) for fastening and adjusting the front panel (12) of a drawer with respect to the side panel (11) comprises a sliding element (26) which is made to slide by shifting means (19, 21) in the direction of the length of the side panel. The sliding element (26) comprises a hook-shaped end (28) which engages with complementary hooking means (32) fitted on the front panel, so as to support the front panel and draw the hooking means close to the device upon operation of the shifting means (19, 21), thereby blocking the movement of the front panel with respect to the side panels of the drawer. The sliding element (26) can be raised by means of an adjusting screw (30) to provide adjustment of the vertical position of the front panel. The shifting means and the adjusting screws are provided with respective control ends protruding from the lower side of the device and extending along a lower edge of the side panel containing the device.Type: GrantFiled: May 3, 1994Date of Patent: October 24, 1995Assignee: Franco FerrariInventors: Franco Ferrari, Carlo Migli

Patent number: 5450655Abstract: A hinge (10) comprises a first (13) and a second (24) fastening element connected to each other by means of a kinematic articulated chain comprising at least two elements (18, 26) articulated to each other and defining space (28) between two of their opposing edges which varies in width upon rotation of the hinge. A further element (31) is secured to at least one of said two elements so as to be pushed by the rotating movement of the hinge to come to rest in correspondence with said space (28). In this way, the space is at least partially obstructed in order to prevent the transversal introduction of slender objects such as fingers.Type: GrantFiled: December 16, 1993Date of Patent: September 19, 1995Assignee: Franco FerrariInventors: Franco Ferrari, Carlo Migli

Patent number: 5373609Abstract: A four-bar linkage hinge comprises two fastening elements (11, 12) with a first (14) and a second link (13) pivoted by their ends, respectively, to each fastening element (11, 12). The first link (14) has an extension (20) which rests on a free arm (25) of a spring (21) which reacts with its other end (24) on one of the two fastening elements, and which exerts pressure on said extension (20) in order to rotate the link to shift the hinge from a nearly closed to a closed position. The arm (25) bears a cam surface with a raised area (28) which is traversed by said extension (20) when the hinge is in the nearly open position, to permit the release of the spring (21) on continuation of the opening movement and push the hinge open.Type: GrantFiled: July 22, 1993Date of Patent: December 20, 1994Assignee: Franco FerrariInventors: Franco Ferrari, Carlo Migli

Patent number: 5025530Abstract: A hinge, in particular for furniture doors, of the type in which a wing is designed to be fitted to a base secured to the piece of furniture, comprises an intermediate element for connecting the wing to the base having a substantially U-shaped transverse configuration to determine two rigid sides which laterally embrace the base.The intermediate element is provided with fastening means for securing it to the wing, and unfastenable means connecting it to the base comprising members yieldingly fitted onto the intermediate element in two portions spaced apart from each other in the longitudinal direction of the wing. The yielding members are elastically biased to move into a position in which they engage with complementary housings in the base in order to couple the intermediate element to the latter, the movement of approach between the base and the wing for the coupling being amply indeterminate.Type: GrantFiled: November 13, 1989Date of Patent: June 25, 1991Assignee: Franco FerrariInventors: Franco Ferrari, Carlo Migli

Patent number: 4212092Abstract: A castor wheel assembly for chairs and the like is disclosed in which the wheel axle and hub are permitted a limited vertical stroke in a slot, a vertically arranged spring being active against the peripheral surface of the axle so that, when the chair is unloaded, the springs of the wheels urge the latter down so that the hubs may engage a friction surface. When the user seats on the chair, the springs are compressed and the rotation of the wheels is unhindered. The total force of the springs in a chair shall overcome the chair's own weight.Type: GrantFiled: September 14, 1978Date of Patent: July 15, 1980Assignee: Agostino Ferrari & C.
