BY M, M f W United States Patent O ZeLZl 'aldklfflt Niles lL. linerstuhl, 3923 W. Alabama, Houston, rtex. Filed Apr. 1, .t9-63, Ser. No. 269,556 6 matins. (fCl. 16-1e3) This invention relates to improvements in two-way hinges, i.e. hinges which allow doors to be pushed or pulled open from either side and the panels of folding screens, etc. to be moved 360 from one side to the other of an adjacent panel.

An important object of the invention is to provide a two-way hinge of novel construction which is economical to manufacture and easily assembled.

It is a further object to provide a two-way hinge which can be quickly and easily assembled on panels, doors, etc., of varying lengths.

It is another object to provide a two-way hinge which employs many identically shaped parts which are easily extruded and fabricated, thus further simplifying the manufacture and assembly of the hinge.

It is another object of the invention to provide a twoway hinge which can be quickly adapted to doors or panels of varying length and which will substantially ll the space between the ends of the panels and the ends of the door on its supporting member when the hinge plates of the hinge are facing each other, thereby eliminating the need for cutting recesses in the ends of the doors or panels to obtain a ilush joint.

Gther objects, features and advantages of the invention will be apparent to one skilled in the art from a consideration of the specification, drawings and appended claims.

FiG. 5 is a sectional View taken along line 5 5 of FlG. 4 illustrating an alternate embodiment of the hinge; and

PEG. 6 is a fragmentary top view of an alternate shape for the hinge plate of the invention.

The two-way hinge of this invention'comprises two hinge plates designed generally by the members 10 and 11, two link members designated generally by the

numbers

12 and 13 and means pivotally connecting the ends ofthe link members to the .hinge plates to allow either hinge plate to move 360 `relative to the other. Thus, the hinge is useful whenever it is desirable to have a hinged member rotate through 360.

ln the embodiment shown in FlG. 1, hinge plates 10 and 11 comprise an assembly of several members which greatly simplies the manufacture and assembly of the hinge. As best seen in FlG. 2, each hinge plate includes two identical support members indicated generally by the letters A, B, C and D. Since they are identical, only member A of hinge 10 will be described generally, with parts of each other member designated by the corresponding letter suix.

The support members are generally rectangularly '@atented Ang. 2li, i965 ICC shaped, having on one corner a cylindrical boss 14a which is provided with a hole 15a. On the same side at the other end, the corner of the support member is cut away to provide an arcuate, concave surface 16a. Vertical grooves 17a and 13a are provided on each side of the member. Groove 17a is rectangularly shaped whereas groove 18a is T-shaped to provide a key slot for

key members

19 and 20. Opening 21a connects the two grooves to receive eyelets 22 used to hold the hinge plate assen.- blies together.

Located between the two support members which make up a hinge plate assembly are

spacer members

25 and 26 which are also identical. They are rectangularly shaped and have T-shaped grooves 27 and 23 of the same size and shape as the T-shaped groove 1'7 in the support members. These spacer members, however, are not as wide as the support members and thereby provide, in effect, a groove extending transversely across the hinge plate assembly to receive the connecting link members l2 and 13 when the hinge plates are assembled as shown in FlG. 1. The hinge pin designated by the numbers 21g-32, which as will be seen below provide the pivot points around which the hinge plate assemblies rotate, are integrally attached to the ends of the link members and extend outwardly from the link members in parallel directions.

The assembled hinge is shown, in FG. 1, attached to panels and 36. As assembled, the hinge plates 10 and 11 are pivotally interconnected through

links

12 and 13 by means of hinge pins 29 through 32. That is, link 13 pivotally connects boss 14a on support member A to boss Mb on support member B and link member 12 pivotally connects boss lftc to boss 14d on support members C and D, respectively.

if the support members were not interconnected by

keyf members

19 and 20, each would be free to rotate around both the pin which is located in the opening in its boss and the pin on the other end of the link member to which it is connected. For example, support member A could rotate around both pin 31 and pin 32 whereas support member E could rotate around both pin 32 and pin 31, etc. However, since support member A is connected to support member C by key 1t), they must rotate together or not at all. Therefore, pin 31 must be in axial alignment with pin 30, which is one of the pins around which support member C rotates, for the hinge plate 10, cornprising members A and C, to rotate. The same is true of hinge plate 11 which comprises support members B and D. Thus, as long as at least two of the pins around which both hinge plates can rotate are in axial alignment, the hinge plates can rotate relative to each other.

. This ability of the hingeplates to rotate around two spaced axes of rotation produces the two-way or 360 hinge effect for this allows each plate to rotate 180 around one axis and an additional 180 around the other for a total of 360.

Suecilically, referring again to the drawings, assume that panel Se is originally in side-by-side relationship with panel 35, as shown by the solid lines of FG. 3, and it is desired to move it to the opposite side. in this position, pins and 31. are in vertical alignment allowing support members B and D, which are interconnected to form hinge plate 11, to rotate around the common axis of the pins. After rotating 90, the hinge and panels are as shown in PEG. 1. After rotating l,-the hinge and panels are as shown in HG. 4. ln this position, both pairs of pins are in axial alignment and either hinge plate can rotate in either direction. lf panel 35 continues rotating, its axis of rotation will shift from the vertical axis of pins 30 and 3l to the vertical axis of

pins

29 and 32. The panel can rotate around the latter axis an additional 180 to its position on the opposite side of panel 35. The panel and hinge plates in this position are shown in dotted lines on the lefthand side of FIG. 3. The dotted lines on the righthand side of FIG. 3 show the hinge when panel 35 is rotated 360 to the opposite side of panel 36.

The preferred embodiment of the hinge comprises hinge plates which are assemblies of two support members and a spacer. The spacer is designed to separate the support members suiciently for the link members to be located between the bosses on the support members. Thus, when assembled, each hinge plate has a boss on opposite edges which are spaced vertically. For example, hinge plate has bosses 14a and 14e on opposite ends and the bosses are spaced apart vertically by the width of the spacer. When assembled, the link members lie in the plane of the spacers and one is pivotally connected to the upper bosses while the other is pivotally connected to the lower bosses.

When the hinge is in the position shown in FIG. 4, with the panels in alignment, the link members overlap each other. By making the width of the spacer less than the width of the support members by at least one-half the width of the link members, the faces of the support members will be flush when the hinge is in this position and the hinge joint can be arranged to completely fill the space between the two panels.

In other words, if the hinge is attached to two panels in the manner shown in FIG. 1, when the panels are in alignment, the ends of the panels will be spaced apart by the total thickness of the hinge. This is particularly undesirable when the panels are parts of a folding screen as these gaps between the end would prevent the screen from providing the desired privacy, etc. One solution is to recess the hinge plates into the ends of the panels far enough to allow the ends of the panels to be ush. However, this involves extra labor and it is difficult to recess the hinges the exact proper distance to obtain the flush joint desired.

By providing the hinge with identically shaped support members and spacers which are capable of being extruded in any desired length, the hinge can be quickly and easily fabricated and assembled to extend the entire length of the panels and thereby provide a flush joint between the panels when the screen is extended.

- For example, a ush joint can be provided between

panels

35 and 36 as follows. Startingat the bottom of the panels, the distance to the rst hinge joint is measured and support members Cand D are cut to that length. These members are then attached either'directly to the end of the panel or they are assembled with keys 19 and 2) along with

spacers

25 and 26 and then attached.

Link members

12 and 13 with the hinge pins attached are located with

pins

29 and 30 of link 12 extending into openings C and 15d. The distance to the next hinge joint is then determined and support members A and B are cut to length and attached to the panel with

pins

31 and 32 of link 13 in openings 15a and 15b. Since the position of the support members can be reversed without affecting the operation of the hinge, support members A and B can then become the lower support members for the next hinge joint. This can be repeated as many times as desired until the upper edge of the panel is reached. The hinged connection thus produced will provide a flush joint between the two panels as shown in FIG. 4 and eliminate any gap between the ends of the panels.

When the hinge isbeing assembled in lplace on the Y have to be installed in the hinge at the time of its assembly. The embodiment of FIG. 5 is provided to allow the hinge plates to be preassembled and interconnected by the link members as the nal step. This would be particularly advantageous when it is desirable to preassemble the hinge plates on a plurality of panels at one location and assemble the panels at another location, or for hanging a door when it is inconvenient to hold the door in position adjacent the door jamb while the hinge is being assembled in place.

In this embodiment, the hinge plates are either preassembled in place on the door or panel, etc., or preassembled as shown in FIG. 1 without the link members and hinge pins. The support members are modified to the extent that plugs 37 are installed in openings 15 in the bosses. The plugs in the lower support member support coil spring 3S in the manner that plug 37d supports spring 33d in FIG. 5. These springs bias the lower pins upward and hold them partially out of their holes. The plugs in the openings of the upper support members are not necessary and can be omitted if desired. Plugs which can be installed during the assembly operation are preferred since this allows the support members to be extruded in the same manner as in the preferred embodiment.

After the hinge plates 10 and 11 are assembled, the hinge pins are installed, the lower pins being resiliently held partially out of their holes vby coil springs 38. After the pins are in place the hinge is assembled by forcing the lower pins downward into the holes 15 against springs 38 and by lifting the upper pins upward against gravity until the space between the bosses is clear of the pins, allowing the link members to be installed. The pins will then enter holes provided therefor in the links, holes 39 and 40 in links 12 and 13' being shown in FIG. 5. The upper pins are urged into the openings by gravity and the lower pins by the springs 3S. This completes the assembly of the hinge. Additional springs can be used in connection with the upper pins where desired and where the hinge is so positioned that gravity cannot be effectively employed or relied upon to hold the pins in the desired position.

FIG. 6 illustrates an alternate shape for the support members which is more readily extruded. By removing a portion of the boss to provide a slot 40, the die forming the support member can be made in one piece which reduces 4its cost considerably. The shape has another .advantage in that unattached hinge pins can be used and, when in position, held against removal/by. crimping the slotted boss against the pinc with a pair of pliers, etc.
