Description
36~
The present invention relates to an improved poster frame and display holder for various types of replaceable posters, pictures and similar advertising materials. The frame and holder can be used in many various areas, such as on buses, taxis cabs, and similar mobile installations, as well as on fixed mounts such as on building walls at service stations, on posts and the like. The poster display device is neat, trim and aesthetic and capable of being used either indoors or outdoors. The device secures a poster or other message sign within its borders and allows replacement thereof in a quick and easy manner.
The present invention is an improvement over the invention disclosed and claimed in U.S. Patent No. 4,145,~28 and assigned to the assignee of the present invention. In that patent a display holder is set forth having a plurality of frame sections. Each of the sections are made essentially of two extruded portions which are pivoted together, the extruded portions being of any material which can be economically extruded, such as aluminum. The extruded frame sections are biased by means of an unbent metal leaf spring to cocci and to releasable clamp posters or similar display items in the frame. The invention as disclosed and claimed in U.S. Patent No. 4,145,828 was itself an improvement over U.S. Patent No. 3,310,901 which employed a cantilever action-type metal leaf springs with S-shaped hooks at one end to bias together the two parts of the frame.
According to the present invention there is provided a closure device which has a first member and a second member rotatable about an axis and movable with respect to the first member between relatively open and relatively closed positions. Resilient biasing means is integrally attached to both the first member and the second member for connecting them together, and the first member, second member ` and the biasing means are made of extruded plastic material and are integrally formed together at the time of extrusion.
The first and second members include relatively rigid material and the biasing means, which provides a force urging the mob/
~t3~6~3~
second member toward -the closed position, comprises a relatively softer material and is elastic and resilient.
According to one aspect of the invention, the first member and the second member define a longitudinal dimension parallel to the axis and the biasing means is fully coextensive with the longitudinal dimension and is substantially enclosed by the first and second members when disposed in the closed position.
More specifically, the invention is a display holder having a plurality of longitudinal frame sections forming a polygonal frame structure for receiving and clamping a display piece in the display holder. The first member being in the form of a base member and the second member being in the form ofamovable cover member, the cover member having holding means for securing the display piece in place.
It may be seen, therefore, that the present invention is capable of providing a poster frame and display holder which is less expensive to manufacture and lighter in weight than the poster frames described in the above named patents. The poster display device of the present invention also is made from a plastic material, is essentially one-piece, and is capable of providing economical frames with relatively small widths (e.g. one-half inch or smaller).
In a specific embodiment, the front portion has an outwardly facing surface on which a decorative simulated metal or simulated wood laminate can be secured. The back portion is formed with an upstanding flange having a pivot ponytail formation thereon The front portion is formed with an inwardly directed flange at a first end thereof and with a second inwardly directed flange at a second end thereof which includes a cup shaped formation adapted to engage the pivot ponytail on the back portion and form a hinge. The elongated biasing section is coupled between the downwardly directed front flange and the upstanding flange, and forms an integral part of the one piece extrusion. The length of the elongated 'I_ mob/
~3~36~3~
biasing member is such that when the pivot ponytail and cup shaped formation are joined to form a hinge, the biasing member is placed under compression causing it to bow towards the front portion. The biasing member thus provides clamping forces between the front and back portion. In one preferred embodiment the resilient biasing section includes living hinges disposed intermediately along the length thereof which facilitate changing or removing posters.
In another embodiment the extruded member serves to clamp the display piece in place from the back side of the display piece against a separate frame member.
It is an object of the present invention to provide a unique and beneficial poster frame and display holder for use in various applications. It is another object to provide a highly durable, weather resistant poster frame and display holder which can be used indoors and outdoors and which will provide a reliable and pleasing appearance throughout its lifetime.

- --~3~2 Description of THE EM2CDIMENTS
As illustrated on Figure 1, the improved display holder and poster frame, generally designated by the reference numeral 10, is made up of a plurality of frame seasickness 12. For a square ox rectangular-shaped Ester four frame sections 12 are normally provided. Ike frame sections are neutered 45 degrees at their ends and fastened together to form a bc~-type fry. A backing Norway of cardboard, fiberboard, or petal is provided and the frame is secured on or around its edges forming the complete poster framing d~vi ox . As shown in Figure 2, each of the sections 12 is made essentially of two pDrticns 14 and 16 being part of a c~T~nDn extrusion which are pivoted together as at 17. The portions 14 and 16 of each section 12 are cut to the desired length and mitered 45 degrees at their opposite ends for abutting and planar assembly with one another to outline the frclme 10. As will key understood, the frame 10 can be square or rectangular, although it is also possible for the frame 10 to have any desired polygonal shape with an appropriate number of sections 12 mitered at appropriate angles. Allah, it is possible for each of the front or cover extrusions 14 to be comprised of a number of extruded pieces of shorter length.
The frame 10 preferably has associated with it a rigid backing member 18 which can be mode of plastic, Masonite aluminum or another suitable material. The sections 12 are positioned around the edges of the backing member 18 handheld in place around its edges by the sections 12 as with pop rivets, for example, to form the oDmpleted display holder. A
poster 19 or other display member is positioned on the backing member 18 Toe back extruded portion 16 can be fastened in any conventional means to a rigid or supporting member, such as a post, will, support frame for a vehicle, or the like. It is also understood that the use of a backing umber 18 is not necessary; the frame 10 Gould be mounted on a flat surface forming its own backing member, or the poster 19 oDuld be made of a rigid or stiff retrial without the need for a bask m g number ,.
I
The portions Al and 16 are Dre~erably made of a plastic material which can be efficiently and economically extruded, and which will present an attractive and durable structure for an in-definite length of time. Suitable materials include polypropylene, vinyl, and rigid polyvinyl chloride.
Adjacent sections 12 of the frame are held and fastened to-getter as by Glenn section to section, by gluing to the backing member 18, or by means of L-shaped corner braces as taught in U. S.
Relent Jo. 3,310,901. The outer or front portion 14 of each frame section is formed with a decorative outer surface 15 and is assembled to the back portion 16 by means of a hinge assembly denoted generally by reference numeral 17. The outer surface 15 preferably is relative-lye flat, but can have any decorative or ridged surface. If it is relatively flat, then it is easier to apply a simulated metal (e. g.
Mueller) or simulated wood laminate to it, The hinge assembly is comprised of a cylindrical hinge or pivot ponytail formation 30 extending outwardly by bridge element 32 from an upstanding flange 34 disposed on back portion 16 and a corresponding cup shaped Formation 36 fowled on the back panel 38 of portion 14. The edges of the cup 36 may extend more than 180 degrees about the pivot 30 in which case the two sections 14 and 16 are snapped together after extrusion to form hinge assembly 17. The edges of cup 36 may alternatively extend less than 180 degrees about the pivot 30 to form hinge assembly 17. As shown by dashed outlines of Figure 2, the hinge assembly 17 allows the cover portion 14 to pivot relative to the back portion 16. Wren the cover portion 14 is in the position show in solid lines in Figure 2, it holds the poster 19 in position in the frame against the backing member 18. when it is desired to remove or replace the poster lo, the cover portion 14 is rotated or pivoted to the dashed outline position 14' permitting the removal of the poster. The rotation of portion 14 is limited by stop end 39 of cup shaped formation 36; when the portion 14 is swung to its fully open position (14') *trade mark hi/ ii 1 .
the end 39 rests against hri~ge element 32 (as shown by dashed outline position 39' in Figure 23.
E~i~nxded portion 14 was a formed side panel or flange 42 thereon with a longitudinal recess 44 formed in it. the recess 44 is prcvidæ 50 that the portion 14 may he grasped in manipulation to open or close it relative to portion 16. m e end 46 of side Panel 42 is adapted to rest on the poster I and cleanup it in place in the display holder.
The upstanding flange 34 is formed with a lip 48 projecting orthogonally inwardly towards the outer of frame 10. The upstanding flange and lip 48 form a recess 50 adapted to engage the backing member lo around its outer edge hid no any tough edges of the backing umber Lip 48 terminates with an ear 52 which provides a stop surf ox or guide surface useful for positioning the poster 19 and keeping it from going too far into the frame. The bridge 32 is attached to upstanding flange 34 and projects generally outwardly from the venter of frame 10, forming a downwardly directed dogleg and terminating in pivot ponytail 30. Bridge element 32 includes a knee portion 54 disposed generally opposite to the pivot ponytail 36.
It will be understood that the structure thus described is extruded of a relatively rigid plastic material such as a vinyl material, including polyvinyl chloride. The invention also comprises an elongated biasing or spring portion denoted generally by reference numeral 60, which is extruded of a relatively resilient material such as estate polyurethane, or ox a softer vinyl material. m e elongated biasing portion 60 is integral with and coupled generally between the end 46 of side panel 42 and knee portion 54~ The union between biasing portion 60 and end 46 forms a transition A between the relatively rigid material of side panel 42 and thy relatively resilient, flexible material of biasing portion 600 the union k~tween biasing portion 60 and the knee 54 of bridge 32 forms a transition B between the relatively rigid bridge and the relatively resilient, flexible biasing portion. Preferably the unions worming transitions A and B are formed during the extrusion process, in other words, the biasing I
portion 60 is of the Amy cue piece extrusion which forms the front part 14 and the back part 16. If desired, transition A nay be formed, as Chicano in Fig. 2, Jo that corner 47 (which contacts poster 19 when the frame is closed) is of the softer material of biasing portion 60. this provides more friction between corner 47 and poster 19 to hold poster 19 in place.
Figure pa Schick the one pie ox extrusion before hinge 17 is assembled. As can be teen, the frame section is extruded with the front and rear portions essentially in their pen positions, but without the pivot ponytail formation 30 and cup shaped formation 36 being nested together. The biasing portion 60 is extruded in a slightly bowed or arcuate configuration, although it can also be extruded in an essentially flat configuration. The running length of biasing portion 60 and bridge 32, as measured Fran a central point A' along interface A to point C at the center of pivot ponytail 30, is made longer than the linear distance between point A' and point C. Thus when hinge 17 is assembled by snapping the cup shaped formation 36 onto the pivot ponytail formation 30, the biasing portion is caused to bow inwclrdly towards the frame front portion 14 a significant extent (or ~Irther if extruded in a slightly bowed condition), as Chicano in Figure 2. This sho~cPns the radius of curvature of portion 60 causing it to exert an inward and outward over-oenter force to stackable retain the movable frame front portion 14 in either its closed or its Cowan positions. In either position, the biasing portion 60 urges the front extrusion 14 in a direction to maintain its integral cup shaped hinge formation 36 snugly against the integral pliantly formation 30 of the back extrusion 16.
Referring to Figures 5 through 10, the spring Aztec of biasing portion 60 is illustrated aver a typical operating range. In Figure 5 the frclme section is shown without poster clipped in pow. file biasing potion 60 is bred inwardly towards the frame front portion 14. A
explais~d cove this inward bowing causes biasing portion 60 to exert forces I font Portia 14 urging it unto its closed pOSitit~la In Figure 6 the frost pi n 16 it Cowan King rotated towards the Cowan . ,:
1 - 7 - _ position shown in Figure 7. As the frame us being opened the biasing portion 60 b~xx~nes even more significantly bowed with an even shorter radius of curvature, as Cowan in Figure 6. Isles increased bowing my ye accounted for by noting that the linear distance between the ends of biasing portion 60 as at A and B has decreased expressing biasing portion 60) a the point A' follows its rotational trajectory about the point C.
In the position shown by Figure 6 the biasing portion 60 continues to exert a do end force tending to close the frame.
At some paint at or near the frame's open position, biasing portion 60 snaps into an cll~twardly bowed position, as shown in Figure 7.
In the a~twardly bud position, biasing potion 60 exerts forces tending to hold front portion 14 in its relatively open position thereby pollinating poster 19 or the like to be positioned within tile frame.
Ike closing sequence is shown in Figures 8 through in. As the front portion 14 is dually rotated towards the closed position against the biasing fortes, biasing portion 60 becomes more significantly outwardly bred. Father rotation towards the closed position, shown in Figure 9, causes more significant bowing of biasing portion 60. In Figure 9 it will be seen that biasing portion 60 b gas somewhat S-shaped in longitudinal cross session At some point at or near the final closed position, Chicano in no 10, biasing portion 60 snaps back into its inwardly bowed position. Zen this occurs the biasing forces produced I biasing portion 60 tend to hold 'eke fryer in its closed position, thereby clamping poster 19 in plate. With particular reference to Figure 9 it will be seen that biasing portion 60 is capable of eonti3cting ear 52, and possibly also poster 19. Such contact, although not essential or rewired, can provide an impetus or nutria for biasing portion 60 snapping awoke into the inwardly bud position of Figure 10.
nether oddment of invention is Chicano in Figure 3. In this embodiment the biasing potion 60, as well us the front portion 14 arid back portion 16, aye extruded ox relatively rigid plush Again the fryer Tao extra in their Jc~en" position as Chicano in solid I

It will also be appreciated that in this embodiment of Figure 3 the living hinge 70 may alternatively be replaced Ruth the pivot ponytail and integral cup shaped formation as described in connection with the first embodiment. The living hinges 72 and 74 old remain, however, at the connection of the biasing portion to the front piece 42 and to the upstanding flange 34.
Still another embodiment is shown in Figure 4. This eddy i t employs the pivoting hinge mechanism 17 of the first embodiment and is extruded as two pieces, although the living hinge 70 of the second embodiment may be substituted for the hinge mechanism 17 in which case a one pie ox extrusion would be used. The biasing portion 60 is coupled as at A to the end 46 of side panel 42 and is extruded of semi rigid plastic material form m g an integral part of the front excision. The biasing or spring portion 60 as exit m dyed is slightly arcuate and terminates in a free standing rounded end portion 80. Toe upstanding flange 34 is formed with a longitudinal, arc shaped groove 82 adapted to pivotal engage end portion 80 upon assembly. the arcuate portion of groove 82 extends approximately 90 degrees and is positioned to allow movement of the end 80 of biasing section 60 over a 30 degree arc as the over portion 14 is opened and closed, while prevent m g the end 80 from being displaced therefrom. m us the biasing portion 60 exerts on inward and outward over-oPnter pharaoh to ~3~6~
stably retain the mcveable frame n partaken in either its closed or its pen position.
Another entxxl~ment, illustrated in Figures 11 thrcwgh 18, employs living hinges disposed intermediately along the length of the elongated biasing section to facilitate clanging or removing posters by prcJvicling a more positive snapping action. As shown in Figllre 11, each of the frame suctions 112 is made essentially of two portions 114 and 116 being part of a common extrusion which are pivoted together as at 117. m e portions 114 and 116 of each section 112 are cut to the desired length and mitered 45 degrees at their opposite ends for abutting and coplanar assembly with one anther to outline the frame. As will be understood, the frame can be square or rectangular, although it is also possible for the frame to have any desired polygc~al shape with an appropriate number of sections 112 mitered at appropriate angles. Also, it is possible for each of the front or cover extrusions 114 to be cx~nprised of a n~nber of e~truc3ed pieces of shorter length.
The frame preferably has associated with it a rigid backing member 118 which can be made of plastic, Masonite aluminum or another suitable material. The sections 112 are positioned around the edges of the backing member 118 and held in pie ox around its edges by the sections 112 as with pop rivets, for example, to form the completed display holder. A
poster 119 or other display member is positionec3 on the backing m~nber 118 The back extruded portion 116 can be fastened in any conventional mean to a rigid or supporting umber such as a post, wall, support frame for a vehicle, Or the like It is also understood that the use of a backing member 118 is not necessary; the frame could be mounted on a flat surface forming its awn backing Myra, or the poster 119 could be made of a rigid or stiff material without the need for a backing number.

End portion 114 has n formed side panel or flange 142 t n with a long Issues 144 formed in it. the recess 144 is provided so that the portion 114 may be grasped in n~nipulation to open or d owe it relative to portion 116. the end 146 of side panel 142 is adapted to rest on the poster 119 and clasp it in place in the display holder.
Ike upstanding flange 134 it formed with a lip aye projecting orthogonally inwardly towards the venter of frame. m e upstanding flange and lip aye form a recess 150 adapted to enrage the backing nabber 118 around its outer edge. Lip 148 ales with an ear 152 which provides a stop surf ox or guide surface useful for positioning the poster 119. The bridge 132 is attached to upstanding flange 134 and projects generally outwardly frump the center of frame, forming a dc~rwardly directed dogleg and terminating in pivot ponytail 130. Bridge elen~nt 132 includes a knee portion 154 disposed generally apposite to the pivot ponytail 136.
It will be understood that the structure thus described is extruded of a relatively rigid plastic material such as a vinyl material, including polyvinyl chloride. the invention also oppresses an elongated biasing or spring portion denoted generally by reference numeral 160, which is extruded of a relatively resilient material such as estate polyurethane, or of a softer vinyl material. m e elongated biasing portion 160 is integral with and copied generally between the end 146 of side panel 142 and knee portion 154. the union between biasing portion 160 and end 146 forms a transition A between the relatively rigid material of side panel 142 and the relatively resilient, flexible material of biasing portion 160.
The union between biasing portion 160 and the knee 154 of bridge 132 forms a transition B between the relatively rigid bridge and the relatively resilient, flexible biasing portion. Preferably the unions forming transitions A and are formed during the extrusion process, in other words, the biasing portion 160 it of the same aye piece extrusion which form the front part 114 and the back pelt 116.

of the length of biasing portion 160. A second living hinge 172 is formed in portion 160 approximately adjacent transition A, coupling intermediate portion 171 ox biasing potion 160 to end portion 173 thereof and to side portion 142. Living hinge 170 ensures that biasing portion 160 Casey outwardly wren the frame is opened, as will be understood with reference to Figure 15. Living hinge 172 coats with hinge 170 to further ensure that the biasing portion 160 boys outwardly when opened. Hinge 172 is disposed apart from transition A to minimize the tendency for the members at transition A to separate.
Figure 12 shows one piece extrusion before hinge 117 is assembled As can be seen, the frame section is extruded with the front and rear portions essentially in their open positions, but without the pivot ponytail formation 130 and cup shaped formation 136 being nested together. The biasing portion 160 is extruded in a slightly bower or arcuate configuration, although it can also be extruded in an essentially flat configuration The m inning length of biasing portion 160 and bridge 132, as measured from a central point A' along interfa ox A Jo point C at the center of pivot ponytail 130, is made longer than the linear distance between point A' and point C. Thus when hinge 117 is assembled by snapping the cup shaped connation 136 onto the pivot ponytail formation 130, the biasing portion 160 is caused to bow inwardly tcwa~ds the frame front portion 114 a significant extent (or further if eta Ted in a slightly bowed condition), as shown in Figure 11. this shortens the radius of curvature of portion 160 causing it to exert an inward and outward ower-oenter for ox to stably retain the movable frame front portion 114 in either its closed or its open positions. In either position, the biasing portion 160 urges the front Tahitian 114 in a dip lion by maintain its `.

integral cup shaped hinge formation 136 snugly against the in-tegral ponytail formation 30 of the back extrusion 116.
Referring to Figures 13 through 18, the spring action of biasing portion 160 is illustrated over a typical operating range.
In Figure 13 the frame section is shown without a roster clipped in place. The biasing portion 160 is bowed inwardly towards the frame front portion 114. As explained above this inward bowing causes biasing portion 160 to exert forces on the front portion 114 urging it into its closed position. In Figure 14 the front portion 116 is shown being rotated towards the open position shown in Figure 15. As the frame is being opened the biasing portion 160 becomes even more significantly compressed or bowed with an even shorter radius of curvature, as shown in Figure 14.
This increased bowing may be accounted for by noting that the linear distance between the ends of biasing portion 160 as at A
and B has decreased (compressing biasing portion 160) as the point A' follows its rotational trajectory about the point C. In the position shown by Figure 14 the biasing portion 160 continues to exert a downward force tending to close the frame.
on At some point at or near the frame's open Position, biasing portion 160 snaps into an outwardly bowed position, as shown in Figure 15. Living hinges 170 and 172 cocci to facilitate the out-ward snapping action. In the outwardly bowed position, biasing portion 160 exerts forces tending to hold front portion 114 in its relatively open position, thereby permitting poster ll9 or the like to be positioned within the frame.
The closing sequence is shown in Figures 16 through 18~ As the front Portion 114 is manually rotated towards the closed position against the biasing forces, biasing portion 160 becomes compressed as seen in Figure 16. Further rotation towards the closed position, shown in Figure 17, causes more significant come press ion of biasing portion 160. In Figure 17 it will be seen that biasing portion 160 becomes somewhat M-sha~ed or cydloidal in longitudinal cross section. At some point at or near the final closed position, shown in Figure 18, biasing portion 160 snaps back into its inwardly bowed position facilitated by hinges 170 and 172.

Lo this occurs the biasing forces produced by biasing portion 160 tend to hold the frame in its closed position, thereby clamping poster 119 in place.
In the above described embodiments, the Duster frame in-mention serves as a front loading poster frame, and the outer surfaces 15 of front portions 14 can be made decorative to improve the appearance of the poster frame. In an alterna-live, back-loading embodiment shown in Figure 19, the poster frame of the invention serves to clam the display piece in Place from the backside of the display piece against a separate frame member. Referring to Figure 19, the separate frame member 180, shown in cross section, may be formed with a shaped or decorative outwardly facing front surface 182 to improve the appearance of the frame. Frame member 180 may be fashioned from conventional picture frame stock, in a wide variety of materials, including wood, plastic, and metal. Frame member 180 is routed or formed to include a first rabbit 184 defining a holding surface 186 in a plane parallel to and adjacent the display piece, and a securing surface 188 generally perpendicular thereto. A second rabbit 190 is routed or formed in the frame member 18n rearwardly of and generally in stair step relation to rabbit 184. Generally speaking rabbit 184 provides a means for attaching the poster frame clamping member of the invention to the frame member 180 and also receives and holds the display piece while rabbit 190 provides clearance space in which clamping member 200 is partially disposed. As used herein, it will be understood that the display piece may comprise a picture, poster 194 or the like, and in certain applications may also include a protective glass or clear plastic layer 192, sand-wicked against picture or poster 194, which in turn may be sandwiched against a layer of corrugated material 196. A rigid backing member 98 is sandwiched behind corrugated material 96 which serves to distribute the clampillg forces generated by the spring loaded poster frame member 200 against the display piece, thereby clamping the disk play piece firmly in place against holding surface 186.
The spring loaded poster frame member or clamping member 200 may be constructed generally according to any of the above-described front hi / Jo loading en~xxl~rents ~nth the following mDdificaticns. With refrain ox to Figure 19 it will be seen that section 202 tithe oDunterpalt of section 12 in the front loading entxxl~ment~ includes a right angular flange 204 or Corey jeans used to secure member 200 to number 180, as by stapling with staples 106 into surf ox 188. In addition section 202 includes cuF-shaped formation 203 for pivotal engagement with ponytail formation 205 oared on section 207. Section 207 (the c~nterpart of section 10 in *he front loading en~Kxl~ment) includes bias portion 260 which may include living hinges it lately along the length thereof according to the en~x~diment illustrated in Figures 11 through 18. In the alternative clamping member 200 may be constructed so that cup-shaped formation 203 is disposed an section 207 and ponytail formation 205 is formed on section 202.
In operation "number 200 f~mc~ions substantially the same as was illustrated and described in connection with Figlu-es 5 through 10 or Figures 13 through 18 Poster frame member 200 may be opened to allow the display pie ox and backing me~bex or members to be removed and replaced.
Member 200 may then key snapped shut to clasp the display piece in place whereupon section 207 is either flush with or slightly recessed with respect to the backside 208 of member 180. The entire frame assembly may then be hung on a wall, or attached to some other securing surface.
Another endowment of the invention is shown in Figure 20. mix frame section embodiment 220 has an upper member 232, a lower member 238 and employs the pivoting h m go mechanism 222 of the embodiment shown in Figure 19 and the bias portion 224 with living hinges of the emkodi~ent shown in Figures 11-18~ Ike lower 1l3~ber 238 has flange 22~ which incorporates a cup-shaped formation 228 for mating and pivotal engagement with ponytail formation 230 formed on upper member 232. It is thought that having the pintle-and-cup stricture made in the manner shown in Figure 20 Rand Figure 19~, rather than the pintle-and-cup structure of Figures 2 and 4-18, would minimize any possible interference of adjacent frame members 220 in toe mitered corners and would also create Jane savings in neutral cysts due Jo use of less material fish I
, , I
, the embodiment 220 employs a bias portion 224 which preferably includes living hinges 234 inte~Tr31iately along the length thereof in a similar nailer to the entxxl~nEnt illustrated in Figure 11-18. The materials used for the member 232 and 238 and for the bias portion 224 are the same as those described above with reference to Figures 11-18~ In this regard, the members 232 and 238 are preferably mode of rigid polyvinyl chloride and the bias portion 224 is preferably made of estate polyurethane, although the invention is net limited to these particular materials.
When the em~xx~nent 220 is prcduoed, it preferably is extruded in the shape shown in Figure aye and then assembled and snapped together to form the cross-sectional shape Chicano in Figure 20. (This is similar to the manner in which the frame sections Sheehan in Figures pa and 12 are extruded). The fewer wrier 238 of fryer section 220 is preferably flat and thus adapted to be secured to a frame backing Burr 240. If toe backing ~rber 240 is Ned of a plastic type n~terial similar to the frame suction 220, then the France sections forming the frame can be secured thereto by ultrasonically welding. In this manner, no corner keys, brazes or the like are needed to secure the frame sections together and a more anesthetically pleasing frame as viewed Fran to back can be secured. yo-yo eliminating the corner braces, a less expensive construction is also possible.
In aeration, the ~bodin~ent 220 motions substantially the same as was illustrated and described in connection with Figures 5-10 or Figures 13-18 and does not have to be repeated here in detail. In general poster frame section 220 may be upend to allow the display piece (and backing m3rber or Myers if aF~>ropriate) to be removed and replaced. Tuber 220 is then snowed shut lo> clasp tube display piece in place While a specific errbodinent of the invention has been illustrated and described, it Rowley be understood that this endowment is provided by way of clue only End that the Sheehan is rut to be o~nstr~ed as being limited thereto, but only my to ode of the fr~llcwinq clown.
The present invention relates to an improved poster frame and display holder for various types of replaceable posters, pictures and similar advertising materials. The frame and holder can be used in many various areas, such as on buses, taxis cabs, and similar mobile installations, as well as on fixed mounts such as on building walls at service stations, on posts and the like. The poster display device is neat, trim and aesthetic and capable of being used either indoors or outdoors. The device secures a poster or other message sign within its borders and allows replacement thereof in a quick and easy manner.
The present invention is an improvement over the invention disclosed and claimed in U.S. Patent No. 4,145,~28 and assigned to the assignee of the present invention. In that patent a display holder is set forth having a plurality of frame sections. Each of the sections are made essentially of two extruded portions which are pivoted together, the extruded portions being of any material which can be economically extruded, such as aluminum. The extruded frame sections are biased by means of an unbent metal leaf spring to cocci and to releasable clamp posters or similar display items in the frame. The invention as disclosed and claimed in U.S. Patent No. 4,145,828 was itself an improvement over U.S. Patent No. 3,310,901 which employed a cantilever action-type metal leaf springs with S-shaped hooks at one end to bias together the two parts of the frame.
According to the present invention there is provided a closure device which has a first member and a second member rotatable about an axis and movable with respect to the first member between relatively open and relatively closed positions. Resilient biasing means is integrally attached to both the first member and the second member for connecting them together, and the first member, second member ` and the biasing means are made of extruded plastic material and are integrally formed together at the time of extrusion.
The first and second members include relatively rigid material and the biasing means, which provides a force urging the mob/
~t3~6~3~
second member toward -the closed position, comprises a relatively softer material and is elastic and resilient.
According to one aspect of the invention, the first member and the second member define a longitudinal dimension parallel to the axis and the biasing means is fully coextensive with the longitudinal dimension and is substantially enclosed by the first and second members when disposed in the closed position.
More specifically, the invention is a display holder having a plurality of longitudinal frame sections forming a polygonal frame structure for receiving and clamping a display piece in the display holder. The first member being in the form of a base member and the second member being in the form ofamovable cover member, the cover member having holding means for securing the display piece in place.
It may be seen, therefore, that the present invention is capable of providing a poster frame and display holder which is less expensive to manufacture and lighter in weight than the poster frames described in the above named patents. The poster display device of the present invention also is made from a plastic material, is essentially one-piece, and is capable of providing economical frames with relatively small widths (e.g. one-half inch or smaller).
In a specific embodiment, the front portion has an outwardly facing surface on which a decorative simulated metal or simulated wood laminate can be secured. The back portion is formed with an upstanding flange having a pivot ponytail formation thereon The front portion is formed with an inwardly directed flange at a first end thereof and with a second inwardly directed flange at a second end thereof which includes a cup shaped formation adapted to engage the pivot ponytail on the back portion and form a hinge. The elongated biasing section is coupled between the downwardly directed front flange and the upstanding flange, and forms an integral part of the one piece extrusion. The length of the elongated 'I_ mob/
~3~36~3~
biasing member is such that when the pivot ponytail and cup shaped formation are joined to form a hinge, the biasing member is placed under compression causing it to bow towards the front portion. The biasing member thus provides clamping forces between the front and back portion. In one preferred embodiment the resilient biasing section includes living hinges disposed intermediately along the length thereof which facilitate changing or removing posters.
In another embodiment the extruded member serves to clamp the display piece in place from the back side of the display piece against a separate frame member.
It is an object of the present invention to provide a unique and beneficial poster frame and display holder for use in various applications. It is another object to provide a highly durable, weather resistant poster frame and display holder which can be used indoors and outdoors and which will provide a reliable and pleasing appearance throughout its lifetime.

- --~3~2 Description of THE EM2CDIMENTS
As illustrated on Figure 1, the improved display holder and poster frame, generally designated by the reference numeral 10, is made up of a plurality of frame seasickness 12. For a square ox rectangular-shaped Ester four frame sections 12 are normally provided. Ike frame sections are neutered 45 degrees at their ends and fastened together to form a bc~-type fry. A backing Norway of cardboard, fiberboard, or petal is provided and the frame is secured on or around its edges forming the complete poster framing d~vi ox . As shown in Figure 2, each of the sections 12 is made essentially of two pDrticns 14 and 16 being part of a c~T~nDn extrusion which are pivoted together as at 17. The portions 14 and 16 of each section 12 are cut to the desired length and mitered 45 degrees at their opposite ends for abutting and planar assembly with one another to outline the frclme 10. As will key understood, the frame 10 can be square or rectangular, although it is also possible for the frame 10 to have any desired polygonal shape with an appropriate number of sections 12 mitered at appropriate angles. Allah, it is possible for each of the front or cover extrusions 14 to be comprised of a number of extruded pieces of shorter length.
The frame 10 preferably has associated with it a rigid backing member 18 which can be mode of plastic, Masonite aluminum or another suitable material. The sections 12 are positioned around the edges of the backing member 18 handheld in place around its edges by the sections 12 as with pop rivets, for example, to form the oDmpleted display holder. A
poster 19 or other display member is positioned on the backing member 18 Toe back extruded portion 16 can be fastened in any conventional means to a rigid or supporting member, such as a post, will, support frame for a vehicle, or the like. It is also understood that the use of a backing umber 18 is not necessary; the frame 10 Gould be mounted on a flat surface forming its own backing member, or the poster 19 oDuld be made of a rigid or stiff retrial without the need for a bask m g number ,.
I
The portions Al and 16 are Dre~erably made of a plastic material which can be efficiently and economically extruded, and which will present an attractive and durable structure for an in-definite length of time. Suitable materials include polypropylene, vinyl, and rigid polyvinyl chloride.
Adjacent sections 12 of the frame are held and fastened to-getter as by Glenn section to section, by gluing to the backing member 18, or by means of L-shaped corner braces as taught in U. S.
Relent Jo. 3,310,901. The outer or front portion 14 of each frame section is formed with a decorative outer surface 15 and is assembled to the back portion 16 by means of a hinge assembly denoted generally by reference numeral 17. The outer surface 15 preferably is relative-lye flat, but can have any decorative or ridged surface. If it is relatively flat, then it is easier to apply a simulated metal (e. g.
Mueller) or simulated wood laminate to it, The hinge assembly is comprised of a cylindrical hinge or pivot ponytail formation 30 extending outwardly by bridge element 32 from an upstanding flange 34 disposed on back portion 16 and a corresponding cup shaped Formation 36 fowled on the back panel 38 of portion 14. The edges of the cup 36 may extend more than 180 degrees about the pivot 30 in which case the two sections 14 and 16 are snapped together after extrusion to form hinge assembly 17. The edges of cup 36 may alternatively extend less than 180 degrees about the pivot 30 to form hinge assembly 17. As shown by dashed outlines of Figure 2, the hinge assembly 17 allows the cover portion 14 to pivot relative to the back portion 16. Wren the cover portion 14 is in the position show in solid lines in Figure 2, it holds the poster 19 in position in the frame against the backing member 18. when it is desired to remove or replace the poster lo, the cover portion 14 is rotated or pivoted to the dashed outline position 14' permitting the removal of the poster. The rotation of portion 14 is limited by stop end 39 of cup shaped formation 36; when the portion 14 is swung to its fully open position (14') *trade mark hi/ ii 1 .
the end 39 rests against hri~ge element 32 (as shown by dashed outline position 39' in Figure 23.
E~i~nxded portion 14 was a formed side panel or flange 42 thereon with a longitudinal recess 44 formed in it. the recess 44 is prcvidæ 50 that the portion 14 may he grasped in manipulation to open or close it relative to portion 16. m e end 46 of side Panel 42 is adapted to rest on the poster I and cleanup it in place in the display holder.
The upstanding flange 34 is formed with a lip 48 projecting orthogonally inwardly towards the outer of frame 10. The upstanding flange and lip 48 form a recess 50 adapted to engage the backing member lo around its outer edge hid no any tough edges of the backing umber Lip 48 terminates with an ear 52 which provides a stop surf ox or guide surface useful for positioning the poster 19 and keeping it from going too far into the frame. The bridge 32 is attached to upstanding flange 34 and projects generally outwardly from the venter of frame 10, forming a downwardly directed dogleg and terminating in pivot ponytail 30. Bridge element 32 includes a knee portion 54 disposed generally opposite to the pivot ponytail 36.
It will be understood that the structure thus described is extruded of a relatively rigid plastic material such as a vinyl material, including polyvinyl chloride. The invention also comprises an elongated biasing or spring portion denoted generally by reference numeral 60, which is extruded of a relatively resilient material such as estate polyurethane, or ox a softer vinyl material. m e elongated biasing portion 60 is integral with and coupled generally between the end 46 of side panel 42 and knee portion 54~ The union between biasing portion 60 and end 46 forms a transition A between the relatively rigid material of side panel 42 and thy relatively resilient, flexible material of biasing portion 600 the union k~tween biasing portion 60 and the knee 54 of bridge 32 forms a transition B between the relatively rigid bridge and the relatively resilient, flexible biasing portion. Preferably the unions worming transitions A and B are formed during the extrusion process, in other words, the biasing I
portion 60 is of the Amy cue piece extrusion which forms the front part 14 and the back part 16. If desired, transition A nay be formed, as Chicano in Fig. 2, Jo that corner 47 (which contacts poster 19 when the frame is closed) is of the softer material of biasing portion 60. this provides more friction between corner 47 and poster 19 to hold poster 19 in place.
Figure pa Schick the one pie ox extrusion before hinge 17 is assembled. As can be teen, the frame section is extruded with the front and rear portions essentially in their pen positions, but without the pivot ponytail formation 30 and cup shaped formation 36 being nested together. The biasing portion 60 is extruded in a slightly bowed or arcuate configuration, although it can also be extruded in an essentially flat configuration. The running length of biasing portion 60 and bridge 32, as measured Fran a central point A' along interface A to point C at the center of pivot ponytail 30, is made longer than the linear distance between point A' and point C. Thus when hinge 17 is assembled by snapping the cup shaped formation 36 onto the pivot ponytail formation 30, the biasing portion is caused to bow inwclrdly towards the frame front portion 14 a significant extent (or ~Irther if extruded in a slightly bowed condition), as Chicano in Figure 2. This sho~cPns the radius of curvature of portion 60 causing it to exert an inward and outward over-oenter force to stackable retain the movable frame front portion 14 in either its closed or its Cowan positions. In either position, the biasing portion 60 urges the front extrusion 14 in a direction to maintain its integral cup shaped hinge formation 36 snugly against the integral pliantly formation 30 of the back extrusion 16.
Referring to Figures 5 through 10, the spring Aztec of biasing portion 60 is illustrated aver a typical operating range. In Figure 5 the frclme section is shown without poster clipped in pow. file biasing potion 60 is bred inwardly towards the frame front portion 14. A
explais~d cove this inward bowing causes biasing portion 60 to exert forces I font Portia 14 urging it unto its closed pOSitit~la In Figure 6 the frost pi n 16 it Cowan King rotated towards the Cowan . ,:
1 - 7 - _ position shown in Figure 7. As the frame us being opened the biasing portion 60 b~xx~nes even more significantly bowed with an even shorter radius of curvature, as Cowan in Figure 6. Isles increased bowing my ye accounted for by noting that the linear distance between the ends of biasing portion 60 as at A and B has decreased expressing biasing portion 60) a the point A' follows its rotational trajectory about the point C.
In the position shown by Figure 6 the biasing portion 60 continues to exert a do end force tending to close the frame.
At some paint at or near the frame's open position, biasing portion 60 snaps into an cll~twardly bowed position, as shown in Figure 7.
In the a~twardly bud position, biasing potion 60 exerts forces tending to hold front portion 14 in its relatively open position thereby pollinating poster 19 or the like to be positioned within tile frame.
Ike closing sequence is shown in Figures 8 through in. As the front portion 14 is dually rotated towards the closed position against the biasing fortes, biasing portion 60 becomes more significantly outwardly bred. Father rotation towards the closed position, shown in Figure 9, causes more significant bowing of biasing portion 60. In Figure 9 it will be seen that biasing portion 60 b gas somewhat S-shaped in longitudinal cross session At some point at or near the final closed position, Chicano in no 10, biasing portion 60 snaps back into its inwardly bowed position. Zen this occurs the biasing forces produced I biasing portion 60 tend to hold 'eke fryer in its closed position, thereby clamping poster 19 in plate. With particular reference to Figure 9 it will be seen that biasing portion 60 is capable of eonti3cting ear 52, and possibly also poster 19. Such contact, although not essential or rewired, can provide an impetus or nutria for biasing portion 60 snapping awoke into the inwardly bud position of Figure 10.
nether oddment of invention is Chicano in Figure 3. In this embodiment the biasing potion 60, as well us the front portion 14 arid back portion 16, aye extruded ox relatively rigid plush Again the fryer Tao extra in their Jc~en" position as Chicano in solid I

It will also be appreciated that in this embodiment of Figure 3 the living hinge 70 may alternatively be replaced Ruth the pivot ponytail and integral cup shaped formation as described in connection with the first embodiment. The living hinges 72 and 74 old remain, however, at the connection of the biasing portion to the front piece 42 and to the upstanding flange 34.
Still another embodiment is shown in Figure 4. This eddy i t employs the pivoting hinge mechanism 17 of the first embodiment and is extruded as two pieces, although the living hinge 70 of the second embodiment may be substituted for the hinge mechanism 17 in which case a one pie ox extrusion would be used. The biasing portion 60 is coupled as at A to the end 46 of side panel 42 and is extruded of semi rigid plastic material form m g an integral part of the front excision. The biasing or spring portion 60 as exit m dyed is slightly arcuate and terminates in a free standing rounded end portion 80. Toe upstanding flange 34 is formed with a longitudinal, arc shaped groove 82 adapted to pivotal engage end portion 80 upon assembly. the arcuate portion of groove 82 extends approximately 90 degrees and is positioned to allow movement of the end 80 of biasing section 60 over a 30 degree arc as the over portion 14 is opened and closed, while prevent m g the end 80 from being displaced therefrom. m us the biasing portion 60 exerts on inward and outward over-oPnter pharaoh to ~3~6~
stably retain the mcveable frame n partaken in either its closed or its pen position.
Another entxxl~ment, illustrated in Figures 11 thrcwgh 18, employs living hinges disposed intermediately along the length of the elongated biasing section to facilitate clanging or removing posters by prcJvicling a more positive snapping action. As shown in Figllre 11, each of the frame suctions 112 is made essentially of two portions 114 and 116 being part of a common extrusion which are pivoted together as at 117. m e portions 114 and 116 of each section 112 are cut to the desired length and mitered 45 degrees at their opposite ends for abutting and coplanar assembly with one anther to outline the frame. As will be understood, the frame can be square or rectangular, although it is also possible for the frame to have any desired polygc~al shape with an appropriate number of sections 112 mitered at appropriate angles. Also, it is possible for each of the front or cover extrusions 114 to be cx~nprised of a n~nber of e~truc3ed pieces of shorter length.
The frame preferably has associated with it a rigid backing member 118 which can be made of plastic, Masonite aluminum or another suitable material. The sections 112 are positioned around the edges of the backing member 118 and held in pie ox around its edges by the sections 112 as with pop rivets, for example, to form the completed display holder. A
poster 119 or other display member is positionec3 on the backing m~nber 118 The back extruded portion 116 can be fastened in any conventional mean to a rigid or supporting umber such as a post, wall, support frame for a vehicle, Or the like It is also understood that the use of a backing member 118 is not necessary; the frame could be mounted on a flat surface forming its awn backing Myra, or the poster 119 could be made of a rigid or stiff material without the need for a backing number.

easing pcrtiDa ~60 is formed with living hinge 170 located intermediate along the loath of portion 160 at a distance D from transition B; where D is less than 50~ and preferably approximately 20~-40~
of the length of biasing portion 160. A second living hinge 172 is formed in portion 160 approximately adjacent transition A, coupling intermediate portion 171 ox biasing potion 160 to end portion 173 thereof and to side portion 142. Living hinge 170 ensures that biasing portion 160 Casey outwardly wren the frame is opened, as will be understood with reference to Figure 15. Living hinge 172 coats with hinge 170 to further ensure that the biasing portion 160 boys outwardly when opened. Hinge 172 is disposed apart from transition A to minimize the tendency for the members at transition A to separate.
Figure 12 shows one piece extrusion before hinge 117 is assembled As can be seen, the frame section is extruded with the front and rear portions essentially in their open positions, but without the pivot ponytail formation 130 and cup shaped formation 136 being nested together. The biasing portion 160 is extruded in a slightly bower or arcuate configuration, although it can also be extruded in an essentially flat configuration The m inning length of biasing portion 160 and bridge 132, as measured from a central point A' along interfa ox A Jo point C at the center of pivot ponytail 130, is made longer than the linear distance between point A' and point C. Thus when hinge 117 is assembled by snapping the cup shaped connation 136 onto the pivot ponytail formation 130, the biasing portion 160 is caused to bow inwardly tcwa~ds the frame front portion 114 a significant extent (or further if eta Ted in a slightly bowed condition), as shown in Figure 11. this shortens the radius of curvature of portion 160 causing it to exert an inward and outward ower-oenter for ox to stably retain the movable frame front portion 114 in either its closed or its open positions. In either position, the biasing portion 160 urges the front Tahitian 114 in a dip lion by maintain its `.

integral cup shaped hinge formation 136 snugly against the in-tegral ponytail formation 30 of the back extrusion 116.
Referring to Figures 13 through 18, the spring action of biasing portion 160 is illustrated over a typical operating range.
In Figure 13 the frame section is shown without a roster clipped in place. The biasing portion 160 is bowed inwardly towards the frame front portion 114. As explained above this inward bowing causes biasing portion 160 to exert forces on the front portion 114 urging it into its closed position. In Figure 14 the front portion 116 is shown being rotated towards the open position shown in Figure 15. As the frame is being opened the biasing portion 160 becomes even more significantly compressed or bowed with an even shorter radius of curvature, as shown in Figure 14.
This increased bowing may be accounted for by noting that the linear distance between the ends of biasing portion 160 as at A
and B has decreased (compressing biasing portion 160) as the point A' follows its rotational trajectory about the point C. In the position shown by Figure 14 the biasing portion 160 continues to exert a downward force tending to close the frame.
on At some point at or near the frame's open Position, biasing portion 160 snaps into an outwardly bowed position, as shown in Figure 15. Living hinges 170 and 172 cocci to facilitate the out-ward snapping action. In the outwardly bowed position, biasing portion 160 exerts forces tending to hold front portion 114 in its relatively open position, thereby permitting poster ll9 or the like to be positioned within the frame.
The closing sequence is shown in Figures 16 through 18~ As the front Portion 114 is manually rotated towards the closed position against the biasing forces, biasing portion 160 becomes compressed as seen in Figure 16. Further rotation towards the closed position, shown in Figure 17, causes more significant come press ion of biasing portion 160. In Figure 17 it will be seen that biasing portion 160 becomes somewhat M-sha~ed or cydloidal in longitudinal cross section. At some point at or near the final closed position, shown in Figure 18, biasing portion 160 snaps back into its inwardly bowed position facilitated by hinges 170 and 172.
