DETAILED DESCRIPTION
(13) FIGS. 1A and 1B show a transformative display 1 according to one embodiment of the disclosure. A number of panels 4a, 4b, 4c are connected with a platform 8 by hinges 6. Each panel fits into a respective recess 14a, 14b, 14c formed in the platform 8. The recesses 14a, 14b, 14c are shaped to conform to the outline of the panels and are deep enough so that, when the panels are in a first configuration, the panels sit below an upper surface of platform 8.
(14) Hinges 6 are provided along an edge of each panel and connect the panel to an edge of the respective recess 14a, 14b, 14c. According to one embodiment, hinge 6 is a barrel hinge that extends substantially along the length of the edge of the panel. According to other embodiments, hinge 6 is comprised of a plurality of separate hinges disposed along the length of the edge of the panel. According to a still further embodiment, hinge 6 is formed by one or more membrane hinges that connect panel 4 and platform 8. FIG. 2A shows a detailed view of one of the panels 4 connected to platform 8 by hinge 6.
(15) Below the recess 14 (that is, one of the recesses 14a, 14b, 14c), one or more spring cavities 18 are provided. FIG. 2A shows a detailed view of a panel with three such spring cavities 18. According to this embodiment, spring cavities 18 each accommodate a coil spring 18a. FIG. 2B shows a detailed view of three barrel hinges 6a, 6b, 6c that connect respective panels 4a, 4b, 4c with platform 8. As shown in FIG. 2A, one end of the spring is connected to a fixed point 21 at an end of the cavity, such as, a bolt or screw. The opposite end of spring 18a is connected with a lever arm 17. Lever arms 17 are connected with each respective panel 4 (i.e., panels 4a, b, c). Sufficient clearance is provided in the spring cavity 18 to allow the lever arm to swing through an arc so that, when spring 18a pulls the end of arm 17 toward fixed point 21, the motion of the arm 17 causes panel 4 (that is, any one of panels 4a, 4b, 4c) to rotate about the axis of hinge 6 to move the panel 4 out of cavity 14 and into an upright position.
(16) As shown in FIG. 1A, latches 19a, 19b, 19c are disposed below the surface 8 of the platform. Latches 19a, 19b, 19c engage with respective holes on the edges of panels 4a, 4b, 4c. In the configuration shown in FIG. 1A, latches 19a, 19b, and 19c engage with panels 4a, 4b, 4c to retain the panels in the respective cavities 14a, 14b, 14c in platform 8. When the latches are actuated, as will be explained below, the panels are driven by springs 18a to swing into the upright position.
(17) FIG. 3A shows a detailed view of latch 19a engaged with hole 16a in panel 4a. FIG. 3B shows a detailed view of one of the latches 19. According to one embodiment, latch 19 is comprised of a shaft 25 that slides through supports 23a and 23b. When moved outward from support 23a, shaft 25 engages with a hole along the edge of a panel, such as hole 16a in panel 4a. According to some embodiments, such as the one shown in FIG. 3A, a spring 15 is provided to drive shaft 25 toward the hole to keep the end of shaft 25 engaged with the hole. According to other embodiment, such as shown in FIG. 3B, no spring is provided. The opposite end of shaft 25 is connected with control cable 24. According to this embodiment, cable 24 is positioned within slot 20 recessed into the surface of platform 8. One or more guides 22 may be provided to facilitate the smooth movement of cable 24. The guides 22 may be formed by smooth sided shafts or sheave screws that allow the cable to slide smoothly around corners of slot 20. According to other embodiments, guides 22 are formed by pulleys.
(18) When tension is applied to cable 24, shaft 25 is pulled away from the edge of the respective panel. This disengages shaft 25 from the hole in the edge of the panel. When shaft 25 disengages from hole 16a, the bias force applied by springs 18a causes panel 4a to rotate about the axis of hinge 6 and move to the upright configuration.
(19) As shown in the embodiment of FIG. 3B, latch 19 includes a reset handle 27 connected with shaft 25. To reset panel 4a back to the horizontal position, the panel is pushed back into recess 14a in platform 8 against the tension of springs 18a. Handle 27 is used to push shaft 25 back into engagement with the hole 16a in the edge of the panel.
(20) According to the embodiment of FIG. 3B, latch 19 includes a stopper 26 positioned between supports 23a and 23b. Stopper 26 limits the travel of shaft 25 so that it remains captive between the supports.
(21) FIGS. 4A, 4B, and 4C show a latch 19 according to another embodiment of the disclosure. Latch arm 45 extends from fulcrum 43. Actuator arm 46 extends from fulcrum 43 opposite from latch arm 45. Arms 45 and 46 can rotate about fulcrum 43. Cable 24, as described in the previous embodiments is connected with actuator arm 46. Tension applied to cable 24 causes actuator arm 46, and hence, latch arm 45 to rotate about fulcrum 43. In the configuration shown in FIG. 4A, latch arm 45 engages with a slot in the edge of a panel, such as panel 4b to hold the panel in the horizontal position against the tension of springs 18a. When latch arm 45 is rotated by tension applied by cable 24, latch arm rotates away from the edge of the panel. In this embodiment, a slot 16b is formed in the edge of the panel instead of a hole. Rotation of latch arm 45 disengages the arm 45 from the slot and allowing the panel 4b to move into the upright position under the force applied by the springs. Reset handle 47 extends upward from actuation arm 46. To reset panel 4b in the horizontal position, the panel is pressed into recess 14b and handle 47 is used to rotate latch arm 45 into engagement with the slot 16b in the edge of the panel 4b.
(22) FIG. 5 shows a top view of a display according to an embodiment of the disclosure. Panels 4a, 4b, 4c are held down into recesses in platform 8 by latches 19a, 19b, 19c, respectively. Cables 24 are connected with the latches. The cables travel through slots 20 in the surface of platform 8. Cable guides 22, for example, sheave screws are provided at corners of slots 20 to allow the cable to move smoothly. Cables 20 are connected with capstan 56 of servo motor 50.
(23) FIG. 6 shows a detailed view of servo motor assembly 50. Servomotor 52 is supported by supports 54 with capstan 56 positioned below the motor. In the embodiment shown in FIGS. 5 and 6, supports 54 are sized so that capstan 56 is coplanar with slots 20. Cables 24 are connected with capstan 56 so that, when motor 52 is energized, cables 56 are pulled by rotation of capstan 56 along slots 20 and away from latches 19a, 19b, 19c. Tension applied to the latches causes them to disengage from panels 4a, 4b, 4c.
(24) According to one embodiment, rotation of capstan 56 applies tension simultaneously on all of cables 24, causing all of the panels 4a, 4b, 4c to be actuated at the same time. According to another embodiment, one or more of cables 24 has slack relative to others of the cables. According to this embodiment, latches connected with cables including slack are actuated slightly later in time as compared with latches operated by cables without slack. This causes the respective panels to be actuated in a predetermined sequence. Such an arrangement allows certain of the panels to reach the full upright position before others. This would allow some portions of the model to be in position to receive engaging features of other portions of the model.
(25) According to other embodiments, instead of a single servomotor 50 connected with all of the cables 24, a plurality of servomotors may be used, each connected to one or more of the cables. This arrangement allows the servomotors to be energized separately, for example, under the control of a computer program, to actuate panels 4a, 4b, 4c according to a programmable sequence. According to other embodiments, instead of a servomotor, cables 24 can be pulled using a pneumatic or hydraulic actuator. According to other embodiment, cables are pulled using a hand-operated lever.
(26) FIGS. 7A and 7B show a transformative scene according to an embodiment of the disclosure. In FIG. 7A, panels 4a, 4b, 4c are in the horizontal position. Certain of the panels may include features that have one appearance when the panels are positioned horizontally within the recesses and another appearance when the panels are positioned vertically. In FIG. 7A, panels 4a and 4c include features 27a and 27c, respectively, that extend perpendicularly from the upper surface of the horizontal panel. These vertical features may be decorated to appear as structures of a first scene. For example, the scene in FIG. 7A might be decorated with visual elements designed to represent a graveyard with elements 27a and 27c being mausoleums.
(27) FIG. 7B shows the model after the panels have been actuated. Panels 4a and 4c form side walls of a building. Vertical features 27a, 27c are shaped to contact one another when the panels are positioned vertically to provide a roof for the building. Panel 4b forms the façade of the building.
(28) In the embodiment of FIGS. 7A and 7B, a resilient floor 32 is provided in the cavity 14b that holds panel 4b. This resilient floor 32 may be formed by providing a rigid panel fitted into the cavity 14b in the substrate 8 that can move up and down within the cavity. The rigid panel is supported by one or more blocks of an elastomeric material, such as a foam, or a rubber. When panel 4b is in the horizontal position, shown in FIG. 7A, floor 32 is compressed beneath the panel. When panel 4b is actuated, floor 32 expands upward, as shown in FIG. 7B. According to some embodiments, the top surface of floor 32 expands to be co-planar with platform 8.
(29) As discussed above, by selecting the lengths of cables 24 connected with latches 19a, 19b, 19c, the sequence of the actuation of the panels relative to one another can be selected. For example, in the example shown in FIGS. 7A and 7B, panels 4a, 4c forming sidewalls can be actuated before panel 4b forming the façade so that the sidewalls and roof of the model building are formed before the façade swings into place.
(30) FIGS. 8A and 8B show a further embodiment of the disclosure. FIG. 8A shows a cross section of a portion of platform 8 and recess 14. Panel 4 is in the first configuration, fitted within recess 14. Hinge 6 connects an edge of panel 4 with an edge of recess 14. Springs, not shown in the figure, bias panel 4 toward the upright, second configuration. Latch 19 holds panel 4 within recess 14, as described for the previous embodiments.
(31) As described with previous embodiments, the upward facing surface of panel 4 includes decorative features as part of a first scene depicted by the model. Extension 27 may be provided on the upward facing surface of panel 4. Extension 27 may be decorated to form a feature of the first scene, for example, a fence, a wall, or the like. Other decorative elements 37 may be provided on the upward facing side of panel 4 to create parts of the first scene, for example, trees, human figures, animals, and the like. In addition, features may be provided on platform 8 in the portion between panels 4a, 4b, 4c that are part of the first scene. For example, human figures 38 might be provided.
(32) As sown in the cross-section view of FIG. 8A, a resilient floor 32 may be positioned below panel 4 in recess 14. Panel 4 compresses floor 32 against the bottom surface of recess 14. Floor 32 will expand upward when panel 4 is actuated. The top surface of floor 32 may include decorative features as part of the second scene, as will be described below.
(33) Swinging feature 34 may be connected with the surface of panel 4 by a hinge 36. Hinge 36 may include a spring that biases feature 34 to swing away from the surface of panel 4. In the configuration of FIG. 8A, swinging feature 34 is held against the downward facing surface of panel 4 by floor 32. Swinging feature 34 could form, for example, the awning of a building or a sign on the building once the scene is transformed.
(34) Instead of, or in addition to a resiliently expanding floor 32, other features may be provided beneath the downward facing surface of panel 4 in the configuration of FIG. 8A. For example, features 39 such as trees, human figures, and the like may be formed from compressible materials and connected with the upper surface of floor 32. These figures are obscured in the first scene while panel 4 is held horizontally.
(35) As with the previous embodiments, when tension is applied to cable 24 by servomotor 52, latch 19 disengages from panel 4, allowing panel 4 to swing upward into the second configuration. FIG. 8B shows panel 4 in the second configuration. Resilient floor 32 expands upward when the compression provided by panel 4 is relieved. Portions of the upper surface of floor 32 expand to be above and/or below the upper surface of the platform. Thus, floor 32 forms elements of the second scene, for example, a curb and sidewalk abutting a portion of a street in front of a building in the second scene. Decorative features 39 on the upward facing surface of floor 32 extend upward. Swinging feature 34 swings outward from the surface of panel 4 and may from an element of the second scene, such as a sign or awning extending from a building that is part of the second scene. In the transformed configuration of FIG. 8B, extension 27 extends horizontally and forms another element of the second scene, for example, a portion of the roof of the building. When all of the panels 4a, 4b, 4c are actuated, the form an enclosed structure that obscures decorative features 37, 38 of the first scene.
(36) FIGS. 9A and 9B show a transformative scene according to another embodiment of the disclosure. As discussed in the previous embodiments a substrate 8 is provided with one or more cavities 14a, 14b, 14c. In the first configuration, shown in FIG. 9A, spring-loaded panels 4a, 4b, 4c are held in their respective cavities by latches as described in previous embodiments. A fixed structure 70 is provided on substrate 8. According to one embodiment, structure 70 represents a portion of a first scene, for example, a house in a warm season of the year. Edges of structure 70 are aligned with the hinges (not shown in this view) connecting panels 4a, 4b, 4c with substrate 8.
(37) FIG. 9B shows the transformative scene after latches have been actuated to allow panels 4a, 4b, 4c to move to their second, vertical position. The panels now obscure the sides of structure 70. As with previous embodiments, the exposed sides of panels 4a, 4b, 4c show a second scene, for example, a house in winter with portions of the panel decorated with frost and snow. As with the previous embodiments, decorative features representing the second scene may be provided within the cavities that are made visible when the panels swing into the vertical position. These decorative features may include figures formed from a resilient material that spring up when the panels are actuated to represent evocative elements, for example, snow covered trees, snowmen, or human figures in winter clothing.
(38) According to one embodiment, the roof of structure 70 includes a transformative section 72. As shown in FIG. 9A, the transformative section has a first surface 72a that forms part of the first scene. In the examples given above, this may be the roof of a house that is free of snow, as a house would be in a warm season.
(39) As shown in FIG. 9B, transformative section 72 has a second surface 72b that is exposed, as will be described below, at the same time panels 4a, 4b, 4c are actuated. Second surface 72b may be decorated to show additional aspects of the second scene, for example, a snow-covered roof consistent with elements of a winter scene provided on the exposed surfaces of actuated panels 4a, 4b, 4c and resilient features provided within cavities 14a, 14b, 14c.
(40) FIGS. 10A-10C show an embodiment of transformative section 72 of the roof in FIGS. 9A and 9B. FIG. 10A shows a portion of structure 70 with transformative section 72 removed. Roof frame 76 surrounds an opening 73 that will fit the transformative section 72. Roof frame 76 is connected with the walls of structure 70. End plates 78 are connected with roof frame 76 on either end of opening 73. Support rod 80 extends between end plates 78. FIG. 10B shows transformative section 72 separate from structure 70. Keeper plates 75 are provided on either end of section 72. First surface 72a and second surface 72b extend between keeper plates 75. Each keeper plate 75 includes a pivot hole 75a. FIG. 10C is a partial view of structure 70. Roof frame 76 is connected with and supported by the walls of structure 70. Rod 80 extends between end plates 78 and passes through pivot holes 75a in keeper plates 75. Materials forming rod 80 and keeper plates 75 are selected to provide low friction so transformative section 72 rotates freely around rod 80. According to one embodiment, a weight (not shown) is provided on an inner face of first surface 72a so that, when transformative section 72 is allowed to rotate, the first surface will be position downward, so that it is inside of structure 70 and obscured and second surface 72b will face upward and be aligned with roof frame 76 to form the exposed roof of the second scene (e.g., of a house in winter). A stop block 77 is provided on one or both of the keeper plates 78. The size and location of stop block 77 is selected so that, when the transformative section rotates so that second surface 72b is upward and aligned with roof frame 76, further rotation is prevented.
(41) FIGS. 11A, 11B, and 11C illustrate the roof servomotor 90 according to an embodiment of the disclosure. As shown in FIG. 11A, servomotor 90 is mounted to one of keeper plates 75 and positioned so that its capstan 92 rotates in a plane aligned with the surface 72b of transformative section 72 when section 72 is positioned with surface 72b facing downward. In the examples given above, in this position first surface 72a is facing upward and forms part of the first scene, i.e., a house in warm weather. FIG. 11B is a view from below structure 70 looking upward at transformative section 72. Capstan 92 of servomotor 90 is connected with actuator arm 94. Actuator arm 94 extends through a slot in keeper plate 78. In the position shown in FIG. 11B, actuator arm 94 contacts an edge of end cap 75 of transformative section 72 and prevents section 72 from rotating. In this position, first surface 72a is held upward so that the display depicts the first scene. Stop block 77 extends from section 72. FIG. 11C shows a perspective view of structure 70 with some walls removed. Actuator arm 94 extends inward through a slot 98 in keeper plate 78. In this embodiment, keeper plate 78 forms one wall of structure 70.
(42) When roof servomotor 90 is energized, capstan 92 rotates, pulling actuator arm 94 in the outward direction through the slot in keeper plate 75. This disengages actuator arm 94 from end cap 75. Because transformative section 72 is weighted to bring second surface 72b upward, disengaging the actuator arm from the end cap causes transformative section 72 to turn over, bringing second surface 72b to the top. When section 72 has rotated 180 degrees, stop block 77 contacts the underside of roof frame 76 so that second surface 72b is aligned with roof frame 76. Actuation of roof servomotor 90 may be simultaneous with actuation of panel servomotor 50 so that panels 4a, 4b, 4c, move from their first horizontal position to their second vertical position covering the walls of structure 50 at the same time the transformative section 72 of the roof of the structure rotates to complete the transformation from a first scene (e.g., a house in summer) to the second scene (e.g., the house in winter).
(43) While illustrative embodiments of the disclosure have been described and illustrated above, it should be understood that these are exemplary of the disclosure and are not to be considered as limiting. Additions, deletions, substitutions, and other modifications can be made without departing from the spirit or scope of the disclosure. Accordingly, the disclosure is not to be considered as limited by the foregoing description.
