Abstract
A frame assembly for picture displays includes support frame elements that have support surfaces on an interior side for supporting a flexible picture carrier. A clamping frame element is pivotally mounted on the support frame element and will move from an open position wherein the picture carrier can be placed onto the support surface, to a closed position in which a portion of the clamping frame element forces the flexible picture carrier toward a recessed flange to create a tension in the picture carrier. A cam tensioning element is used for holding and locking the clamping frame element in its closed position. The cam can be made adjustable if desired.
Description
- The present application claims the benefit of priority under the International Convention based upon German Patent Application No. 102004 063 366.5, filed Dec. 30, 2004.
- The present invention relates to a frame component for constructing picture display frames as well as to a frame for picture displays constructed therefrom. The invention is also directed to a novel display.
- Picture displays are used to a great extent for advertising, both inside and outside. Involved essentially are flat prints or image carriers that are tensioned on frames or are disposed in frames, and that, depending upon the application, are covered with a protective sheet, for example, of glass or plastic, and if needed, the prints are also back lighted. In the case of back lighting, an opaque diffusing screen is necessary for diffusing the light.
- The frames used for constructing such displays generally include a base frame that carries the construction and that generally has side frame components or segments formed from an open extruded box section, primarily for reasons of weight. The components are joined at corners to form a periphery. Outer individual frame components or segments that surround the print or image carrier form an outer frame and are generally pivotably secured to the base frame components or segments, and overlie the base frame segment so that the outer frame segments can be pivoted away from the base frame segments to an open position for the insertion of a picture or picture carrier, and after insertion of the picture and pivoting the outer frame segments back to a closed position, the outer frame covers and holds the picture edges in a visually attractive manner. In this connection, the picture is generally disposed between a support flange of the base frame and the cover frame segments and is clamped in place with the cover frame when the cover frame segments are closed.
- In particular for constructing large-surface displays, the picture carriers should be able to be presented in a manner that is as free of creases as possible and has a planar surface appearance but this is a problem with existing frames. A planar surface appearance is also desirable with small display formats, and even with picture carriers that are covered with protective sheets it is often the case that the picture carrier has a waviness or distortion behind the cover.
- Although when clamping frames are used, spring elements are frequently disposed between support frame and clamping frame for pre-tensioning the clamping frame relative to the support frame, the spring forces are frequently inadequate to exert a sufficient pressure of the clamping frame upon the picture carrier in order to be able to present the latter in a manner free of creases.
- The present invention provides a frame component, as well as a frame for constructing picture displays that enable a presentation of flexible sheet picture carriers or pictures that are essentially free of creases or wrinkles, and also enable an easy exchange of the picture carrier in the frame with another picture carrier.
- For the technical realization of this object, the invention proposes a frame component for constructing picture display frames, including a support or base frame element and a clamping frame element that is pivotably disposed on the support or base frame element. The clamping frame element can be held closed to clamp a picture carrier with a tensioning device for maintaining the closed pivotal position of the clamping frame element relative to the support frame element which elements are configured to provide a tension in the picture carrier.
- With the present inventive approach, it is now possible to insure that the pivot position of the clamping frame element relative to the support frame element is at a fixed location. One thus has the possibility of subsequently tensioning the clamping frame relative to the support frame, and hence increasing the pressure the clamping frame exerts on the picture carrier to create tension in the picture carrier. The pivotal position of the clamping frame element can be controlled so that the picture carrier remains under a suitable tension, but remains undamaged.
- Pursuant to an advantageous embodiment of the invention, the support frame element has a picture support edge that is offset relative to the position of the pivot axis. The pivot axis is generally disposed on the surface of the support frame element at the level of the plane of the supported picture or picture carrier, and parallel thereto. The clamping frame element is coupled to the pivot axis and is openable and closable so it covers the edge of the picture carrier that would be seen by a viewer. The picture support surface or edge is a region at the upper surface of the support frame member upon which the picture carrier edges are placed. The picture carrier edges are retained on the support wall with a suitable device, as shown with hook and loop fasteners of the type sold under the trademark VELCRO. Pursuant to the invention, the support surface for the picture carrier is formed with an offset flange portion that is lower than a portion retaining an edge of the picture carrier. The clamping frame element forms the visible surface of the picture frame, and extends in the direction toward the middle of the picture and will engage the retained picture carrier and force the flexible picture carrier toward the offset flange portion to create tension in the picture carrier.
- The flexible picture carrier edge rests and is retained upon an upper surface portion of the support frame element and the picture extends toward the center of the picture frame to overlie the lower offset flange portion. The clamping frame element is spring loaded to bear on the picture carrier and urge it toward the offset flange. There is thus a tension exerted upon the picture carrier as the clamping frame element is pivoted to a closed position.
- Pursuant to a further advantageous embodiment of the invention, the support frame element has at least one formed box member. This can be an extruded member or a member formed in the desired cross section with a plurality of individual elements fastened together.
- The tensioning device that forces the clamping frame element to a fully closed position and which can lock it closed can be constructed in a variety of ways. In the simplest case, it involves, for example, a cam that can be moved out of the support frame element to exert a force on a leg of the clamping frame element on an outer side of the pivot. This action presses the inner edge of the clamping frame element upon the picture carrier to urge it toward the offset flange. Adjustment or locking cams can also be formed at various locations.
- The actuation for the individual cams can be mechanical, but they can also be hydraulic, or pneumatic cylinder operated. The tension adjustment cams can be mechanically coupled to one another and centrally actuatable.
- Adequate tension in the picture carrier can be transferred by the tensioning arrangement through the clamping frame element onto the picture carrier, so that the picture carrier is free of creases or wrinkles. The clamping frame element is also secured against unintentional pivoting to an open position with the cams. To this extent, the tensioning device can also be provided with further securement means, e.g., locks or the like.
- The invention also provides a frame for picture displays with which at least one side is formed from the described support frame element having a pivoting clamping frame element thereon.
- Thus, the picture carrier, which is a flexible sheet, such as a film or thin plastic or other backing, can be tensioned in at least one direction.
- Pursuant to a further advantageous function of the invention, the picture carrier attachment using hook and loop fasteners (sold under the trademark VELCRO) has one of the strips of the hook and loop fasteners disposed on the support frame element. The free end of the picture carrier can have the corresponding part of the fastener on the underside at the supported edge and thus the edge can be retained or secured in place on the support frame element. This securement location is on the support surface to the outside of the offset flange on the support frame element. The clamping frame element then exerts pressure upon the picture carrier toward the offset flange, thereby resulting in the picture carrier being tensioned.
- It is advantageously proposed that the picture carrier be a film or thin sheet of plastic. It is to be understood that the ability of the picture carrier to be tensioned depends upon its strength. The invention can thus be combined with measures for reinforcing the picture carrier. In this connection, it is particularly advantageous, if the picture carrier is a film of plastic, which these days can be digitally printed and which is very resistant to any type of tearing, cutting into, and the like. The term picture carrier is to mean all types of pictures and illustration supported on the frame elements.
- The invention is advantageously used for a light box display with the frame of the light box formed from at least one of the frame element assemblies of the present invention. The frame element assembly, including the base or support frame element and the pivoting clamping element is very effective to provide a wrinkle free picture carrier, in a display frame, and yet is low cost.

FIG. 1 is a fragmentary corner assembly of a light box having a frame made according to the present invention; -
FIG. 2 is a cross-sectional illustration of one embodiment of the invention taken online 2--2 inFIG. 1 with a clamping frame element open; -
FIG. 3 is a cross-sectional illustration also taken online 2--2 inFIG. 1 with the clamping frame element closed; -
FIG. 5 is an illustration taken online 2--2 inFIG. 1 with the clamping frame element held in an adjusted, locked position; -
FIG. 6 is a front view of the adjusting device with parts of the frame elements broken away. - As shown in
FIGS. 1-4 , theframe element assembly 1 includes a base support frame element ormember 2 and a clamping frame element ormember 3. In this connection, the components can be extruded elements, for example of aluminum that can be anodized. However, the frame elements are formed in a specific profile, as shown, and can also be multi-sectional and can be composed of a plurality of elements fixed together. - A part cylindrical pivot rail 4 (
FIGS. 2, 3 and 4) is formed on the support frame element ormember 2 at the upper side. Therail 4 extends along the length of the support frame element ormember 2. The clamping frame element ormember 3 has aninturned edge 3B and asocket 3A that receives therail 4 and pivots thereon. A pivot axis is formed for the clamping frame element on therail 4. A leaf orflat spring element 5 has one end disposed in aspring receiving groove 3C formed on an inner side of atension creating wall 3D that extends downwardly from the main wall of the clamping frame element at the inner edge or side of the clamping frame element. - The opposite end of the leaf or
flat spring element 5 is positioned in agroove 3E formed adjacent to thepivot rail 4, and to the interior or inner side of thesupport frame element 2. As can be seen in the Figures, the flat orleaf spring 5 is bowed to exert a force that produces a pre-load or bias on the pivotingclamping frame element 3. In the position shown inFIG. 2 , the line of force exerted by theleaf spring 5 relative to thepivot axis 4 is such that theclamping frame element 3 is held in its open position, and in the position shown inFIG. 3 , the line of force of the flat orleaf spring 5 relative to the pivot axis of thepivot rail 4 is such that it will urge theclamping frame element 3 to be held in the closed position, and this is further emphasized in the position shown inFIG. 4 . Thesupport frame element 2 has a laterally extendingwall 6 that extends toward an inner side of the frame from thepivot rail 4, and forms asurface 6A that is a support frame for a picture carrier or film shown at 13. - As shown schematically, the edge of the
film 13 is held or retained on the support surface ofwall 6 with two strips of hook and loop fasteners, and one of the strips is shown at 7 on theupper surface 6A of thesupport wall 6, and the other portion is shown at 14A adjacent anedge 14 of thepicture carrier 13. - The
wall 6 has theupper support surface 6A as shown, and has an inwardly extendingflange portion 8 formed integral with the wall and offset to be lower or offset from the plane of thesurface 6A as shown. In other words, the support wall for the edge of the picture carrier has two levels, including thesupport surface 6A for the edge of a picture carrier, and theflange 8 that is recessed or below thesupport surface 6A. Thesupport surface 6A is below the plane of the axes of the pivot rails 4 when the frame is assembled as well. - The support frame element or
member 2 is a box construction as shown, and has an elongated inner side wall 9, and has a base orlower securement flange 10 that can be used for attaching to a back wall or the like for forming a light box, the corner of which is shown inFIG. 1 at 29.FIG. 1 also illustrates that the flat orleaf spring 5 is formed into short segments that extend between the support frame element and the clamping frame element. Thelight box 25 includes suitable lights indicated at 27 supported on aback wall 29. The lights can be fluorescent type light bulbs or other suitable lights that will illuminate the picture carrier shown at 13 inFIG. 1 . - While the inner side wall 9 of the
support frame element 2 is shown as being parallel to the outer side wall of thesupport frame element 2, these walls can be made in any inclination desired. - The
picture carrier 13 can be placed onto thesurface 6A ofsupport wall 6 using the securing hook andloop fastener portions clamp frame element 3 in its open position as shown inFIG. 2 . The picture orimage carrier 13 can be a suitable plastic film, as stated, so that it is flexible and is of suitable size so that it can be placed in the frame exemplified by the two members shown inFIG. 1 at one corner. A full rectangular frame can be utilized that can be quite large for supporting the picture carriers. Picture carriers in the range of 2 meters by 2 meters or larger can easily be placed into the frame assembly. - When the picture carrier is retained in place on the
support surface 6A, essentially as shown inFIG. 3 , the clampingframe member 3 can be pivoted on therail 4 to its partially closed position shown inFIG. 3 where the end of theinclined wall 3D will engage the upper surface of thepicture carrier 13. The hook and loop fasteners will prevent the picture carrier from moving relative to thesurface 6A so thatouter end wall 3D of theclamping frame member 3 will start to push the picture carrier downwardly toward theflange 8. - The clamping
frame member 3 can then be moved manually, and under spring pressure, to the position shown inFIG. 4 . If desired, the clamping frame member can be moved to this closed, clamping position and held there by a cam tensioning element illustrated generally at 11, which includes acam member 12. Thetensioning element 11 comprises ahousing 11B that pivotally mounts thecam member 12 about an axis, and thehousing 11B is placed between the wall 9 of the frame member, and an outer wall of the support frame element in a suitable location. Several of the cam members can be used along the length of the frame, and if desired, thehousing 11 can have a recess for aspring element 11A that acts against thecam member 12 and will retain it in two positions. - Referring to
FIG. 5 , the housing for thespring 11A is shown schematically, and thehousing 11 extends of sufficient length so that thecam member 12 is within thehousing 11 in its dotted line position or retracted position ofFIG. 5 . When thecam member 12 is moved to its extended locking position shown in solid lines inFIG. 5 , it engages the under surface of theedge portion 3B of theclamp frame element 3, and forces theclamp frame element 3 to its fully closed position as shown inFIG. 4 . This operation of thecam member 12 can be obtained by moving a mountinghub 12A, which has asquare drive opening 12B using atool 15 that fits into the square drive opening. The tool can be rotated to rotate the cam member and lock theclamping frame element 3 in the position shown inFIG. 4 . The end portion of thewall 3D will engage thepicture carrier 13 in the location above or overlying the upper surface of theflange 8. -
FIG. 3 shows the partially closed position of the clampingmember 3, and the flat orleaf spring 5 will be exerting a resilient force to start to tension thepicture carrier 13. The tensioning cam member orelement 12 is operated via theclamping tool 15 which comprises a spanner wrench having a square end that fits into thesquare opening 12B of thehub 12A for the cam member to rotate the cam. Depending on the degree of rotation, the cam member exerts a pressure upon clampingelement 3. This clamping pressure is shown by thearrow 17 inFIG. 4 , and this will create a tension inpicture carrier 13. - The rotation of the
cam member 12 is frictionally loaded by thehub 12, and the position and outer configuration of the cam member can be selected so that the tension indicated by thedouble arrow 17 is adjustable to suit existing circumstances. Also, the cam profile can be selected to be any desired profile for obtaining the necessary tension in the picture carrier. - It should be noted that the ability to create tension in the picture carrier is established by having the support wall flange B at a different level from the retaining members for the edge of the picture carrier on
surface 6A, and by utilizing a cam that can not only adjust the pressure but can lock the clamping frame member orelement 3 in position so the clamping member is not opened unintentionally. - Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
