United States Patent Office Patented June 23, 1970 3,516,114 HINGE Edward F. Joyce III, 114 Beach St., Rockaway, NJ. 07866 Filed Oct. 14, 1968, Ser. No. 767,245 Int. Cl. E0511 9/00 U.S. Cl. 16-450 8 Claims ABSTRACT OF THE DISCLOSURE A hinge assembly has a bridge type pintle formed with cylindrical edges having two radii of curvature to define radial abutments. The edges of the pintle rotate in cylindrically cunved sockets of hinge members. The sockets are formed with radial abutments. When the hinge is closed opposite edges of the sockets engage edges of the pintle. When the hinge is opened, abutments of the pintle and hinge members engage in cooperation with engagement of edges of the hinge members with edges of the bridge of the pintle.

The present invention is directed at providing an improved hinge construction Which more effectively joins lids of a cabinet, or many other applications.

In my prior Pat. No. 2,318,362, I have described a hinge for a chest-type cabinet which has a pair of hinge members joined by a pintle having cylindrical side edges engaged in cylindrical sockets in the hinge members. The pintle has a curved narrow bridge joining its two cylin' drical edges. This bridge engages edges of the hinge sockets when the hinge is opened and closed respectively. If the lids of the chest joined by the hinge assembly do not fit properly, or if the hinge is subject to extreme strain on being open or closed, the hinge is liable to break at the bridge of the pintle.

A principal object of the invention is to provide an improved hinge having a bridge type pintle, wherein the pintle and hinge members have abutments to cooperate with the bridge in resisting strain on opening and closing.

A further object is to provide an improved hinge of the type described, wherein the hinge adapts and conforms more readily to poorly fitting lids, or other applications.

Another object is to provide an improved hinge as de scribed, wherein there is greater play permitted between hinge members when the hinge is opened to allow for irregularities in cabinet structure.

A further object is to provide a hinge having a bridge type pintle wherein opposite edges of the pintle are not constrained to rotation on axes precisely parallel to axes of the sockets in which edges of the pintle are engaged.

Various objects, features and advantages of the inven tion will become apparent upon reading the following specification together with the accompanying drawing forming a part thereof.

Referring to the drawing:

FIG. 1 is a perspective view of a hinge assembly embodying the invention.

FIG. 2 is an end view of the hinge shown in closed position and engaged to a lid of a cabinet and to a wall of the cabinet, or other application.

FIG. 3 is a horizontal sectional view taken on line 44 of FIG. 2.

FIG. 4 is an end view of the hinge, lid and wall of the cabinet with lid and hinge shown in fully opened position.

FIG. 5 is an enlarged end view of parts of the hinge assembly in partially open position.

FIG. 6 is a perspective view, partially in section of another hinge assembly embodying the invention.

Referring first to FIGS. 1-5, there is shown a hinge assembly 10 having two hinge members 12a, 12b and a pintle 16. The hinge members have identical shapes and can be formed as extrusions of aluminum, plastic or other suitable materials. The pintle has a symmetrical shape and can also be formed as a metal or plastic extrusion of any desired length.

Each hinge member has a flange 17a or 17b with a channel 18 on its underside which can receive threaded shanks of screws 20, 22 (see FIGS. 2-4). The screws can be inserted in tapped holes 23 or can be of self-tapping type to tap their own holes. Ridges 24, 25 and 26 and 24', 25 and 26 of the hinge members bear on and frictionally engage upper surfaces 28, 30 of the cabinet wall 32 and lid 34, respectively. Facing lateral flanges 38a, 38b of the hinge members engage in recesses 40a, 40b formed in facing edges of the wall 32 and lid 34. Generally cylindrical sockets 42a, 42b are formed in outer sides of the hinge members. The sockets extend circumferentially more than 180 and at their inner edges are formed with rails 45a, 45b defining radial abutments.

The pintle 16 has an arcuate bridge 46. Opposite edges of the bridge are integrally with lateral cylindrical ridges 48a, 48b of the pintle. Each pintle edge has a major cylindrical portion 49a or 49b of greater radius of curvature and a minor cylindrical portion 50a or 50b of smaller radius of curvature. The major cylindrical portions extend more than 180 while the minor portions extend about 120 (see FIG. 5). The remaining circumferential extent of the ridges 48a, 48b is occupied by the ends of the bridge 46. Inner corners a, 55b of the bridge coincide with inner edges of cylindrical portions 50a, 50b. Outer corners 56a, 56b of the bridge coincide with outer edges of cylindrical portions 49a, 49b. Radial abutments 58a, 5811 are defined at steps between the major and minor cylindrical portions of the pintle ridges 48a, 48b.

When the pintle is closed with respect to the hinge members, as shown in FIGS. 1, 2, and 3 and at the left hinge member 12a in FIG. 5, the pintle is held in sockets 42a, 42b by engagement of outer socket edges 60a, 60b with major cylindrical portions 49a, 4% while rails 45a, 45b engage the inner cylindrical portions 50a, 50b at bridge 46. A space S extends circumferentially between the ridges of the pintle and the inner walls of the sockets because the radii of the socket are greater than those of the ridges so that a certain amount of play is permitted between the pintle and hinge members. This permits the hinge members to conform to a cabinet and lid or other application whose upper surfaces 28, 30 are not coplanar and may be somewhat skewed with respect to each other. This contrasts with the hinge construction referred to in my prior Pat. 2,318,362 in which the hinge accommodates to wall and lid surfaces which are parallel and slightly oifset, but wherein the hinge will not accommodate to wall and lid surfaces slightly skewed to each other.

When the hinge assembly is fully opened as shown in FIG. 4 and at the right hinge member 12b of FIG. 5, edges 60a, 60b of the hinge members engage at corners 49a, 49b of the bridge 46 while rails 45a, 45b of the hinge members engage at radial abutments 58a, 58b of the pintle ridges. The strain at the bridge 46 is relieved and reduced by the cooperating engagement of the rails and abutments, as clearly shown in FIG. 4. This contrasts with the hinge construction of my rior patent where the corner joints of the bridge bear the full strain of a fully opened lid, so that the hinge is subject to breakage at the bridge. Circumferential space S accommodates the hinge to warped or skewed lids.

FIG. 6 shows a hinge assembly 10A which has the same basic construction as hinge assembly 10 and corresponding parts are identically numbered. In assembly 10A the flanges a, 70b of the hinge members 12a, 12b

are fiat and may be provided with countersunk holes 72 to receive screws for mounting on a fiat cabinet wall and lid, respectively. Operation of the hinge member in closed and open positions is the same as described in connection with hinge assembly 10.

The hinge assemblies and 10A will bear greater lid weights and will withstand rougher handling than my prior hinge assembly. At the same time, the benefits of economy of manufacture and ease of assembly are retained.

In assembling the hinges, the pintle ridges 48a, 48b are slid longitudinally into the sockets. Permanent locking of the hinge members and pintles against relative longitudinal movement can be effected by forming recesses (n t shown) in the pintle edges and upsetting adjoining edges of the sockets in the same manner as described in my prior patent.

What is claimed is:

1. A hinge assembly adapted for pivotally joining to a lid or cabinet wall or any two objects to be hinged, comprising a first elongated hinge member having a first flange adapted for connection to a surface of said wall, said hinge member having a first cylindrical socket extending the full length of said member, said socket being open laterally and extending circumferentially more than 180 but less than 360, said socket having a first rail extending radially inward thereof at one edge of the socket; a second elongated hinge member; a second flange adapted for connection to a surface of said lid, said second hinge member having a second rail extending radially inward thereof at one edge of the second socket, said members having lateral sides facing each other when the hinge members are in open position; and a pintle coupling the two hinge members, said pintle having generally cylindrical ridges at opposite lateral edges and an arcuate center longitudinally extending bridge integrally joining the ridges, each ridge having a major cylindrical portion of greater radius of curvature extending the full length of he pintle and extending circumferentially more than 180, each ridge having a minor cylindrical portion of smaller radius of curvature extending the full length of the pintle and extending circumferentially less than 180,

so that a radial abutment is defined between the minor.

and major cylindrical portions, said ridges being rotatably engaged in the first and second sockets, respectively, whereby when the hinge members are in fully open position the rails of the hinge members engage opposite inher corners of the bridge at said minor cylindrical portions of the ridges while outer corners of the bridge at said major cylindrical portions of the ridges engage at other edges of the sockets.

2. A hinge assembly as defined in claim 1, wherein the radius of curvature of each socket is greater than the radii of curvature of the ridges so that a circumferentially extending space exists between the ridges and sockets in both open and closed positions of the hinge members to permit the hinge members to accommodate to irregularities in the surfaces of the Wall and lid.
