ABSTRACT
An improved hinge of the type having two concentric, part circular hinge elements. One hinge element, in cross-section, has a base with a part-circular pi-tle and a part-circular arm concentric about the pintle. A radial web connects the pintle to the arm inwardly of the arm. The second hinge element has a base and second and third part-circular arms extending from one side of the base. The second and third arms curve toward each other with a substantial gap between their free ends. The first and second hinge members slidably interconnect with the pintle within the third arm, the third arm within the first arm, and the first arm within the second arm.

Description
BACKGROUND 0~ THE IN~ENTION

The invention is more particularly directed toward an improve~ hinge of the type comprising elongate, concentric, part-circular hinge elements.
The invention is also directed toward a folding closure employing the improved hinge.
1. ~ield of the Invention This invention is directed toward an improved hinge.
The invention is more particularly directed toward an improve~ hinge of the type comprising elongate, concentric, part-circular hinge elements.
The invention is also directed toward a folding closure employing the improved hinge.
2. Description of the Prior Art Hinges having concentric circular hinge elements are well suited for use in folding closures. The hinges provide weather-proof joints between adjacent closure panels and also provide smooth, reliable pivoting action at all stages of opening and closing. In addition, the part-circular hinge elements make it easy to assemble the hinges by sliding one hinge element partly within the other. A separate pintle is not normally required to assemble the hinges. Hinges of the above type are quite well known as shown for example in applicant's U.S. Patent 3,359,594.
While the advantages of using the concentric part-circular hinge elements are many, there are problems associated in their use. The elements are ideally suited to be manufactured by extrusion. However the cross-sectional shape of the elements, to provide a smooth operating hinge, is usually such that their extrusion is extremely difficult. The problem arises from having to extrude a hinge element having two arms curved toward each ot~er, the free ends of which are close to each other. The narrow gap between the ends requires an expensive extrusion die which has to be frequently replaced. The circular pintle element used in the known hinges is also difficult to manufacture and further is wasteful of material since a 360 pintle surface is not essential. Problems are also encountered in mounting the hinge elements to the panels and aligning the hinged panels.
SUMMA~Y 0~ THE INVENTION
It is therefore a purpose of the present invention to provide a hinge comprising concentric part-circular elements which is more inexpensive to manufacture while still retaining ease of assem~ly and operation. It is a further purpose of the present invention to provide hinge elements which can be easily installed to panels. It is another purpose to provide a closure which can ~e easily assembled and aligned.
`: ~
The invention provides hinge elements designed to be easily extruded, using a minimum amount of material, while still provid-ing contacting surfaces arranged to provide smooth operation.
~he hinge elements are also designed to provide ease of mounting on the panels, and to each other.
The invention is particularly directed toward a hinge having first and second elongated hinge members. The first hinge member has a base and a pintle spaced from one side of the base. A first curved arm extends from the one side of the base about the pintle and a first web connects the pintle to the first ar~ inwardly from the free end of the arm. The second hinge member also has a base, a second curved arm extending from one side of the second base and a third curved arm extending from the one side of the second base. The second and third arms curve toward each other and have a substantial gap between their free ends. The first and second hinge members slidably inter-connect with the pintle located within the third arm, the third arm located within the first arm and the first arm located with-in the second arm.

DESCRIPTION O~ THE PRE~ERRED EMBODIMENTS
The innge 1 of the present invention is particularly suited for use in folding c~osures 3. The folding closures 3 are of the type comprising a plurality of full-sized elongated, rec-tangular panels ~ and two half-size elongated rectangular panels 1$17715 5a, 5b. All the panels 5 are pivotably joined together with the hinges 1 along their long sides 7. Panel 5a is pivotably joined to one end of panels 5 by a hinge 1 along one of its long sides 7a, and panel 5b is pivotably joined to the other end of joined panels along one of its long sides 7b by a hinge 1. The hinged panels 5 are each pivotably suspended from the center of their top edge 9, from a trolley 11 running on a track 13 mounted on a top *rame member 15. 'rOp frame member 15, together with side frame members 17, define the rectangular opening 19 to be closed by the closure 3. The closure 3 is fixed along the one free side of one of the half side panels 5a, 5b to one of the side frames. As shown in FIG. 1 free side 7a of panel 5a is fixed to side frame 17a. The panels 5 are folded in zig-zag or accordian fashion about the hinges 1 to be stored adjacent the one side frame 17a when the closure 3 is opened to open opening 19. To close the opening 19, the panels 5 are unfolded, moving along track 13, to bring the free side 7b of the other half panel 5b adjacent the other side frame 17b. In this closed position, the panels 5 are almost aligned. Stop means are provided to prevent the panels from becoming aligned in order that the closure may be easily opened.
In more detail, each hinge 1, connecting two adjacent panels 5 together, comprises two elongated hinge members 21, 23. As seen in cross-section in ~IG. 4 the first hinge member 21 has a generally rectangular base 25. The base 25 has connecting means 27 at one side 29 for use in connecting it to one long side 7 of a first panel 5. The first hinge member 21 has a pintle 31 spaced a short distance from the other, opposite, parallel side 33 of base 25. The pintle 31 comprises a part-cylindrical ele-ment. The pintle element preferably comprises approximately three-quarters of a cylinder with the slot opening 37 in the cylinder generally facing the base 25. A first curved arm 39 extends from the other side 33 of base 25 about the pintle 31.
This first arm 39 preferably is almost semi-cylindrical in cross-sectional shape and is concentric about the pintle 31. The arm 39 is attached, adiacent one edge 41, to the end of a short web 43 extending perpendicularly from one edge of the other side 33 of base 25. A web 51 connects the pintle 31 to first arm 39.
The web 51 preferably extends radially from pintle 31 and connects to the first curved arm 39 about two-thirds of the distance along the length of the arm ~rom its edge where it is ~oined to the web 43. The opposite free edge 53 of first arm 39 is preferably rounded.
1~17715 The second hinge member 23, as seen in cross-section in ~IG. 5, also has a generally rectangular base identical to the base 25 of first member 21. The base 25 has panel connecting means 27 on one side 29, as before, for use in connecting it to the long side 7 of an adjacent panel 5. A short web 63 extends perpendicularly from the other side 33 of the base 25, along one edge of the base. A second curved arm 67 is attached along one edge 69 to the inner side 71 of the web 63 at a position closely adjacent the other side 33 of base 25. Second arm 67 is prefer-ably nearly semi-cylindrical in cross-sectional shape. A third curved arm 73 extends from the other, outer side 75 of web 63 at the end of the web. The third arm 73 is also preferably part-cylindrical in cross-sectional shape and extends radially approx-imately 120' from the end of web 63. The third arm 73 is curved in the opposite direction to second arm 67 so that both arms face each other and both are arranged to be concentric. Both free ends 77, 79 of arms 67, 73 respectively, are rounded and spaced apart radially about 60 to provide a relatively wide gap 80 between them.
The secondcurved arm 39 on first member Zl is arranged to have its one edge 41, and the central axis 81 of pintle 31 which is also the central axis of arm 39, in a plane 83 which is per-pendicular to side 33 of base 25. The second curved arm 67, on second member 23, is arranged to have its one edge 69 and the central axis 85 of arm 67, in a plane 87 which extends at an obtuse angle ~ to side 33 of base 25. Angle ~ is approximately 105.
The panel connecting means 27 on each hinge member 21, 23 can comprise a through hole 101 in the bases 25 having a rec-tangular cross-sectional shape. A centrally located, longitudin -al slot 103 in side 29 provides access to the hole 101. A part-cylindrical groove 105 is provided in the center of side 107 of rectangular hole 101 opposite the side 109 in which slot 103 opsns.
Each panel 5 is formed with connecting means 111 on its sides 7 cooperating with the connecting means ~7 on the bases 25 of the hinge members 21, 23. The panel connecting means 111 as shown in FIG. 6, comprises a rectangular bar 113 sized to sub-stantially fîll rectangular hole 101 with the web 115 of panel 5, attached perpendicular to, and centrally to, bar 113, sized to pass through slot 103. The side 117 of bar 113, opposite web 11~, and ~acing side 107 of hole 101, has a part cylindrical groo~e 119 mating with groove 105 to pro~ide a circular hole 121.
1~7715 One hinge member 21 is mounted on one side of each panel 5 and the other hin&e member 23 is mounted on the other side of each panel 5. The hinge members 21, 23 are mounted on each panel by merely siding each hinge member onto the connecting bar 113 at each side of the panel, the bars 113 passing into holes 101.
After the hinge members 21, 23 have been mounted on the panel, a self-tapping screw 123 is threaded into hole 121 from each end to lock the hinge members to the panel as shown in FIG. 6.
The full panels 5, with one hinge member 21 fixed to one long panel side and with the other hinge member 23 fixed to the other long panel side, are now assembled by sliding the one hinge member 21 on one panel, within the other hinge member 23 on an adjacent panel. In more detail the hinge members 21, 23 are joined together, as shown in FIG. 6 by sliding the pintle 31 of member 21 between the second and third arms 67, 73 of member 23. The center 81 of pintle 31 corresponds to the center 85 of arms 67, 73 when the members 21, 23 are slidably connected. The inner surface 125 of second arm 67 as shown in FIGS. 4 and 5 has a radius Rl just slightlygreater than radius R2 of the outer surface 127 of first arm 39. The inner surface 129 of first arm 39 has a radius R3 slightly gre~er than the radius R4 of the outer surface 131 of third arm 73. The inner surface 133 of third arm 73 has a radius R5 slightly greater than the radius R6 of the outer surface 135 of the pintle 31.
A self-tapping screw 141, carrying a washer 143 large enough to cover the outer arms 39, 67 of hinge members 21, 23 i8 now threaded into the bottom open end of pintle 31 as shown ln FIG. 1. The washer 143 supports the panel carrying hinge member 23 from the panel carrying the hinge member 21 to maintain adjacent panels together. The outer side of each o~er hal~
panel ~a, 5b is attached by a hinge 1 to a closure end member 145. Each end member 145 as shown in ~I~. 2 can have a generally rectangular, hollow, cross-sectional shape. An inwardly directed ~-slot 147 can be provided in the center on the narrow sides 149 of the mem~er. A connector 151 is provided ha~ing a narrow panel 1~3 with a small rectangular cross-bar 155 at one end and a larger rectangular, cross-bar 157 at the ot~er end. Cross-bar 135 is similar to bar 113 on the sides of the full or half panels and has a part-circular groove 159 in its outer side 161. r~he con-nector 1~1 is attached to hinge 1 by small cross-bar 155 sliding into hole 101, and to end member 145 by large cross-bar 157 slid-ing into rr-slot 147. ConnPctor 151 is fixed to end member 145 by suitable means, not shown, and can be he~d to hinge 1 by a self-tapping screw.

DESCRIPTION O~ THE PRE~ERRED EMBODIMENTS
The innge 1 of the present invention is particularly suited for use in folding c~osures 3. The folding closures 3 are of the type comprising a plurality of full-sized elongated, rec-tangular panels ~ and two half-size elongated rectangular panels 1$17715 5a, 5b. All the panels 5 are pivotably joined together with the hinges 1 along their long sides 7. Panel 5a is pivotably joined to one end of panels 5 by a hinge 1 along one of its long sides 7a, and panel 5b is pivotably joined to the other end of joined panels along one of its long sides 7b by a hinge 1. The hinged panels 5 are each pivotably suspended from the center of their top edge 9, from a trolley 11 running on a track 13 mounted on a top *rame member 15. 'rOp frame member 15, together with side frame members 17, define the rectangular opening 19 to be closed by the closure 3. The closure 3 is fixed along the one free side of one of the half side panels 5a, 5b to one of the side frames. As shown in FIG. 1 free side 7a of panel 5a is fixed to side frame 17a. The panels 5 are folded in zig-zag or accordian fashion about the hinges 1 to be stored adjacent the one side frame 17a when the closure 3 is opened to open opening 19. To close the opening 19, the panels 5 are unfolded, moving along track 13, to bring the free side 7b of the other half panel 5b adjacent the other side frame 17b. In this closed position, the panels 5 are almost aligned. Stop means are provided to prevent the panels from becoming aligned in order that the closure may be easily opened.
In more detail, each hinge 1, connecting two adjacent panels 5 together, comprises two elongated hinge members 21, 23. As seen in cross-section in ~IG. 4 the first hinge member 21 has a generally rectangular base 25. The base 25 has connecting means 27 at one side 29 for use in connecting it to one long side 7 of a first panel 5. The first hinge member 21 has a pintle 31 spaced a short distance from the other, opposite, parallel side 33 of base 25. The pintle 31 comprises a part-cylindrical ele-ment. The pintle element preferably comprises approximately three-quarters of a cylinder with the slot opening 37 in the cylinder generally facing the base 25. A first curved arm 39 extends from the other side 33 of base 25 about the pintle 31.
This first arm 39 preferably is almost semi-cylindrical in cross-sectional shape and is concentric about the pintle 31. The arm 39 is attached, adiacent one edge 41, to the end of a short web 43 extending perpendicularly from one edge of the other side 33 of base 25. A web 51 connects the pintle 31 to first arm 39.
The web 51 preferably extends radially from pintle 31 and connects to the first curved arm 39 about two-thirds of the distance along the length of the arm ~rom its edge where it is ~oined to the web 43. The opposite free edge 53 of first arm 39 is preferably rounded.
1~17715 The second hinge member 23, as seen in cross-section in ~IG. 5, also has a generally rectangular base identical to the base 25 of first member 21. The base 25 has panel connecting means 27 on one side 29, as before, for use in connecting it to the long side 7 of an adjacent panel 5. A short web 63 extends perpendicularly from the other side 33 of the base 25, along one edge of the base. A second curved arm 67 is attached along one edge 69 to the inner side 71 of the web 63 at a position closely adjacent the other side 33 of base 25. Second arm 67 is prefer-ably nearly semi-cylindrical in cross-sectional shape. A third curved arm 73 extends from the other, outer side 75 of web 63 at the end of the web. The third arm 73 is also preferably part-cylindrical in cross-sectional shape and extends radially approx-imately 120' from the end of web 63. The third arm 73 is curved in the opposite direction to second arm 67 so that both arms face each other and both are arranged to be concentric. Both free ends 77, 79 of arms 67, 73 respectively, are rounded and spaced apart radially about 60 to provide a relatively wide gap 80 between them.
The secondcurved arm 39 on first member Zl is arranged to have its one edge 41, and the central axis 81 of pintle 31 which is also the central axis of arm 39, in a plane 83 which is per-pendicular to side 33 of base 25. The second curved arm 67, on second member 23, is arranged to have its one edge 69 and the central axis 85 of arm 67, in a plane 87 which extends at an obtuse angle ~ to side 33 of base 25. Angle ~ is approximately 105.
The panel connecting means 27 on each hinge member 21, 23 can comprise a through hole 101 in the bases 25 having a rec-tangular cross-sectional shape. A centrally located, longitudin -al slot 103 in side 29 provides access to the hole 101. A part-cylindrical groove 105 is provided in the center of side 107 of rectangular hole 101 opposite the side 109 in which slot 103 opsns.
Each panel 5 is formed with connecting means 111 on its sides 7 cooperating with the connecting means ~7 on the bases 25 of the hinge members 21, 23. The panel connecting means 111 as shown in FIG. 6, comprises a rectangular bar 113 sized to sub-stantially fîll rectangular hole 101 with the web 115 of panel 5, attached perpendicular to, and centrally to, bar 113, sized to pass through slot 103. The side 117 of bar 113, opposite web 11~, and ~acing side 107 of hole 101, has a part cylindrical groo~e 119 mating with groove 105 to pro~ide a circular hole 121.
1~7715 One hinge member 21 is mounted on one side of each panel 5 and the other hin&e member 23 is mounted on the other side of each panel 5. The hinge members 21, 23 are mounted on each panel by merely siding each hinge member onto the connecting bar 113 at each side of the panel, the bars 113 passing into holes 101.
After the hinge members 21, 23 have been mounted on the panel, a self-tapping screw 123 is threaded into hole 121 from each end to lock the hinge members to the panel as shown in FIG. 6.
The full panels 5, with one hinge member 21 fixed to one long panel side and with the other hinge member 23 fixed to the other long panel side, are now assembled by sliding the one hinge member 21 on one panel, within the other hinge member 23 on an adjacent panel. In more detail the hinge members 21, 23 are joined together, as shown in FIG. 6 by sliding the pintle 31 of member 21 between the second and third arms 67, 73 of member 23. The center 81 of pintle 31 corresponds to the center 85 of arms 67, 73 when the members 21, 23 are slidably connected. The inner surface 125 of second arm 67 as shown in FIGS. 4 and 5 has a radius Rl just slightlygreater than radius R2 of the outer surface 127 of first arm 39. The inner surface 129 of first arm 39 has a radius R3 slightly gre~er than the radius R4 of the outer surface 131 of third arm 73. The inner surface 133 of third arm 73 has a radius R5 slightly greater than the radius R6 of the outer surface 135 of the pintle 31.
A self-tapping screw 141, carrying a washer 143 large enough to cover the outer arms 39, 67 of hinge members 21, 23 i8 now threaded into the bottom open end of pintle 31 as shown ln FIG. 1. The washer 143 supports the panel carrying hinge member 23 from the panel carrying the hinge member 21 to maintain adjacent panels together. The outer side of each o~er hal~
panel ~a, 5b is attached by a hinge 1 to a closure end member 145. Each end member 145 as shown in ~I~. 2 can have a generally rectangular, hollow, cross-sectional shape. An inwardly directed ~-slot 147 can be provided in the center on the narrow sides 149 of the mem~er. A connector 151 is provided ha~ing a narrow panel 1~3 with a small rectangular cross-bar 155 at one end and a larger rectangular, cross-bar 157 at the ot~er end. Cross-bar 135 is similar to bar 113 on the sides of the full or half panels and has a part-circular groove 159 in its outer side 161. r~he con-nector 1~1 is attached to hinge 1 by small cross-bar 155 sliding into hole 101, and to end member 145 by large cross-bar 157 slid-ing into rr-slot 147. ConnPctor 151 is fixed to end member 145 by suitable means, not shown, and can be he~d to hinge 1 by a self-tapping screw.
1~77~
i~hen all the full and half panels 5, 5a, 5b in the closure
3 have been connected together, each full panel 5 is then pivot-ably suspended from a trolley 11 at the center of its top edge 9 by a suitable pivot mounting pin 165. The pin 165 can be fixedly mounted at its lower end 167 within a cylindrical hole 169 formed in the center of each panel 5 between its sides 7 as shown in L'IG. 3. '~he upper end 171 of pin 165 is rotably mounted in trolley 11.
When the closure 3 is operated to close opening 19, adjacent panels 5 pivot away from each other about their common pintle 31 with the outer surface 127 of first arm 39 sliding along the inner surface 125 o* second arm 67 and the inner surface 133 of third arm sliding about the outer surface 135 of pintle 31. This movement continues until the closure is closed with free end 77 of second arm 67 nearly abutting on web 43 and the free end 53 of first arm 39 nearly abutting on web 63 on each hinge. If abut-ment between some adjacent panels does occur during closing, it occurs before the adjacent panels become aligned due to the slight angulation ;of second arm 67 relative to the side 33 of the base 25 of the second member. The abutting action, before alignment, ensures that the closure can open without difficulty.
When the closure 3 is opened, the panels fold accordian-style with the third curved arm 73 on second hinge member 23 moving about the pintle 31 into the curved space 175 between surfaces 135, 129 on pintle 31 and first arm 39 respectively, un~il its free end 79 abuts web 51. At this point adjacent panels 5 are substantially parallel to one another. If desired, each base 25 could be provided with shoulders 177 proiecting from its end at side 33 so that these shoulders a~ut to slightly space the panels 5 from each other at the completion of opening, and thus provide clearance for the trolleys 11 to move adjacent each other.
Both the hinge members 21, 23 can be readily extruded from suitable material without difficulty due to their novel con -struction. The relatively wide gap 80 between arms 67, 73 in hinge mem~er 23 allows member 23 to be relatively inexpensively extruded since the exruding die does not require a narrow neck.
The panels, 5, connectors 151 and end members 145 can also be readily extruded ~rom suitable material.
When the closure 3 is operated to close opening 19, adjacent panels 5 pivot away from each other about their common pintle 31 with the outer surface 127 of first arm 39 sliding along the inner surface 125 o* second arm 67 and the inner surface 133 of third arm sliding about the outer surface 135 of pintle 31. This movement continues until the closure is closed with free end 77 of second arm 67 nearly abutting on web 43 and the free end 53 of first arm 39 nearly abutting on web 63 on each hinge. If abut-ment between some adjacent panels does occur during closing, it occurs before the adjacent panels become aligned due to the slight angulation ;of second arm 67 relative to the side 33 of the base 25 of the second member. The abutting action, before alignment, ensures that the closure can open without difficulty.
When the closure 3 is opened, the panels fold accordian-style with the third curved arm 73 on second hinge member 23 moving about the pintle 31 into the curved space 175 between surfaces 135, 129 on pintle 31 and first arm 39 respectively, un~il its free end 79 abuts web 51. At this point adjacent panels 5 are substantially parallel to one another. If desired, each base 25 could be provided with shoulders 177 proiecting from its end at side 33 so that these shoulders a~ut to slightly space the panels 5 from each other at the completion of opening, and thus provide clearance for the trolleys 11 to move adjacent each other.
Both the hinge members 21, 23 can be readily extruded from suitable material without difficulty due to their novel con -struction. The relatively wide gap 80 between arms 67, 73 in hinge mem~er 23 allows member 23 to be relatively inexpensively extruded since the exruding die does not require a narrow neck.
The panels, 5, connectors 151 and end members 145 can also be readily extruded ~rom suitable material.
