The present invention is related to amusement devices, and more particularly, may be embodied as a greeting card product utilizing paper mechanics as a primary form of attraction.
Over the years, designers have utilized a wide variety of features to make greeting cards and related gift items more attractive and desirable to consumers. In addition to the use of various colors, pictures, designs and phrases, cards have also been designed with selectively moveable portions in an effort to draw attention to the card. A popular means for incorporating some form of motion into a greeting card is to employ paper mechanics technology with the moving items being located inside the card. The particular arrangement of folds in the paper or cardstock inside the card make it such that the motion is generally caused by the opening and closing of the card, creating what is commonly referred to as a “pop-up” effect. While paper mechanics technology is well known and can provide for various types of movement, this method of imparting movement in the card is generally limited to linear up and down or side-to-side motion within the interior of a card. For example, by moving the card from a folded to an unfolded position, this motion extends opposite ends of a planar paper layer away from each other causing a central portion of the paper to pivot outward and upward from the card as the card opens. Alternatively, a tab fixed to a movable paper item on a right side of the card is pulled leftward as the card opens. Although current paper mechanics provide for pivoting from a bottom of the card to a top of the card or sliding from a right side to a left side of the card, they do not provide for more complex motions without additional electrical or non-paper mechanical mechanisms. For example, a small electric motor may be placed within the card, but this solution can be bulky, more expensive, and make undesirable noise compared with paper mechanics solutions. Therefore, it is desirable to provide a different method of imparting more complex movement to objects within a card which are not limited by the drawbacks of the prior art.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description section. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The scope of the invention is defined by the claims.
Embodiments of the invention are directed to a movable lever and spiral lift device for providing an animated and/or “pop-up” product that may be incorporated into a greeting card, a book, or the like. The lever and spiral lift design, also referred to herein as a cam lift mechanism, allows for rotational motion and/or outward extension of two-dimensional and/or three-dimensional decorative paper or paperboard elements in a greeting card, book, or other pivotally-opened item upon opening thereof. Furthermore, the paper mechanics design of the device provides a compact product for ease of handling by the user.
Aspects described herein provide for an openable apparatus that includes a decorative portion mechanically driven by a cam lever that in turn harnesses the work input by the consumer in opening the apparatus. In one aspect, the openable apparatus takes the form of a greeting card assembly, including a card body panel having a first subpanel and a second subpanel separated by a fold, one or more cam lift mechanisms actuatable by pivoting at least one of the subpanels at the fold, and one or more decorative elements set in motion by actuation of the one or more cam lift mechanisms. The second subpanel may have one or more cam slots or openings formed therethrough. The one or more cam lift mechanisms may include a rotating portion rotatably attached to the second subpanel via a primary axle, one or more tab portions integral with or fixed to the rotating portion and extending through the cam slots, and a cam lever flexibly or rotatably attached to the rotating portion (e.g., via one or more secondary axles). The cam lever may also be fixedly attached to the first subpanel, such that opening of the card (i.e., pivoting of one of the subpanels in a direction away from another of the subpanels) rotates the one or more cam lift mechanisms about the primary axle.
The tab portions may slide from a first end of the cam slots to a second end of the cam slots upon rotation of the one or more cam lift mechanisms. This sliding is caused by opening of the card body panel that pulls the cam lever in a lateral direction (e.g., from right to left) from a first position to a second position, which in turn rotates the rotating portion about the primary axle. The cam slots may be straight or slightly curved elongated channels and may each have the first end spaced a first radial distance from the primary axle and the second end spaced a second radial distance from the primary axle. The first radial distance is greater than the second radial distance. The tab portions may attach to outer edge portions of the one or more decorative elements, thereby rotating and/or causing the decorative elements to extend outward (i.e., pop up) from the card when the card is opened. For example, the cam slots may guide the rotating tab portions inward toward the primary axle, thereby guiding portions of the decorative elements inward and causing the decorative elements to pop up or extend away from the card body panel.
Additional advantages and features of the invention will be set forth in part in a description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention.
The present invention is described in detail below with reference to the attached drawing figures, wherein:
The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or a combination of steps similar to the ones described in this document, in conjunction with the other present or future technologies.
A greeting card in accordance with various embodiments described herein is shown throughout the figures. As explained more fully herein, the greeting card employs a cam lift mechanism to generate animation and outward extension of certain design elements in response to user initiated input of opening the greeting card or otherwise manually activating the cam lift mechanism. Although the cam lift mechanism is described herein as being integrated into a modified version of a traditional greeting card or similar structure, note that other similarly-openable structures (e.g., a book, a magazine, a brochure, a table decoration, or the like) can incorporate this cam lift mechanism without departing from the scope of the embodiments described herein. The decorative elements being animated or extended outward, along with other indicia positioned on the greeting card, provide a theme (e.g., birthday, anniversary, or the like) for the amusement of the user.
Referring now to the drawings in more detail and initially to
The second subpanel 22 includes one or more openings formed therethrough, generally referred to herein as cam slots 34, as illustrated in
In some embodiments, the card body panel 12 may include a back cover subpanel (or a third subpanel) 42 or any number of additional subpanels configured to hide non-aesthetic portions of the greeting card assembly 10 from view. Such non-aesthetic portions may include, for example, portions of the primary axle 14 or cam lift mechanism 16. The back cover subpanel may be integrally formed with and/or fixedly attached to the second subpanel 22. For example, the back cover subpanel 42 may have a first side edge pivotally attached along a second fold line to the second side edge of the second subpanel 22. Alternatively, the back cover subpanel's first side edge may alternatively be pivotally attached to the first side edge of the first subpanel 20 and a second side edge of the back cover subpanel 42 may be pivotally attached to the first side edge of the second subpanel 22. In either embodiment, the second subpanel 22 may be attached to the back cover subpanel 42 such that when the card body panel 12 is in the closed position, the second subpanel 22 is located between the first subpanel 20 and the back cover subpanel 42.
Furthermore, when the card body panel 12 is in the open position, the second subpanel 22 may at least partially cover the back cover subpanel 42. In some embodiments, when transitioning from the closed position to the open position, the second subpanel 22 and the back cover subpanel 42 may be fixed together to cooperatively pivot away from the first subpanel 20. At least a portion of the cam lift mechanism 16 may be rotatably attached in a space between the second subpanel 22 and the back cover subpanel 42, such that the back cover subpanel 42 protects the cam lift mechanism 16 from catching on anything, such as the user's hand while they hold the card body panel 12.
The primary axle 14, as depicted in
The cam lift mechanism 16, as illustrated in
The rotating portion 44 may also include an extended arm portion 52 that extends or protrudes outward from a predominating geometric shape of the rotating portion 44. In one example embodiment, the extended arm portion 52 may be an elongated protruding arm integrally formed with and extending from a hexagonal segment of the rotating portion 44. The rotating portion 44 may also have a second rotating portion opening 54, formed off-center relative to the first rotating portion opening 50 and the primary axle 14. In some embodiments, the second rotating portion opening 54 may be formed through the extended arm portion 52 proximate to an end thereof, as depicted in
In some embodiments, the one or more tab portions 46 can be integral with or attached to the rotating portion 44. The tab portions 46 may extend through the cam slots 34 and can attach to the at least one decorative element 18, such that a majority of each of the tab portions 46 can be positioned between the back surface 28 of the first subpanel 20 and the front surface 30 of the second subpanel 22 when the card body panel 12 is in the closed position as in
The cam lever 48 may be a drive shaft configured to move laterally from a first position to a second position when the first subpanel 20 is pivoted about the fold 24 in a direction away from the second subpanel 22. Specifically, the cam lever 48 may slidably extend through a cam lever opening 58 formed through the second subpanel 22. For example, the cam lever opening 58 may be slightly wider than the cam lever 48 and in some embodiments may be at least partially covered by a cam lever opening flap 60. Furthermore, the cam lever 48 may be rotatably attached to the rotating portion 44 (such as at the secondary axle 56) and integrally formed with or fixedly attach to the back surface 28 of the first subpanel 20. The cam lever 48 may slide away from the second subpanel 22 when the first subpanel 20 is pivoted away from the second subpanel 22. When the cam lever 48 moves laterally from the first position (as depicted in
As illustrated in
The decorative element 18 can include a decorative panel having a plurality of folds configured such that the decorative panel rests in a first folded configuration when the card body panel 12 is in the closed position and at least a portion of the decorative panel is extended in a direction away from the second subpanel 22 into a second unfolded configuration when the card body panel 12 is moved from the closed position to the open position. Specifically, this second unfolded configuration occurs due to the outer edge portions 62 of the decorative panel being pushed closer to each other and radially closer to the primary axle 14, as guided by the cam slots 34, when the rotating portion 44 is rotated by the cam lever 48 moving from the first position to the second position.
Furthermore, in some embodiments, the decorative element 18 or the decorative panel thereof may have a center portion 66 of a geometric shape such as a hexagon and each edge of the hexagon may have a flap 68 extending therefrom and integral thereto, joining at a first fold or crease with the hexagon edge. Note that the center portion 66 is merely located inward of the flaps 68 and does not require being exactly centered relative to any other component. Each of the flaps 68 may have a second fold separating a first and a second portion of the flap 68, with the first portion of the flap 68 attached to the hexagon-shaped center portion and the second portion of the flap 68 attached to one of the tab portions 46 on the cam lift mechanism 16. Thus, in the closed position of the card body panel 12, as in
As illustrated in
In some embodiments, for example as illustrated in
In some embodiments, for example as illustrated in
In this embodiment, a cam lever 348 or yoke is provided that is pivotally coupled to both the first rotating portion 344 and the second rotating portion 380. As such, movement of the cam lever 348 from a first position (as in
As can be appreciated, the various embodiments of the greeting card assembly and its various components can provide numerous combinations of decorative elements and three-dimensional pop-up designs activated via rotation of portions of the decorative elements radially inward or radially outward. Other embodiments of and modifications to the invention are beneficial as well and are within the scope of the present invention. For example, the movement of the components can be used to produce mechanical or electronic sounds.
In some alternative embodiments, the first subpanel 20 of the card body panel 12 may be omitted and the cam lever 48 may be laterally moved from the first position to the second position manually by a user pulling the cam lever 48 or a tab attached to the cam lever 48. Additionally or alternatively, the second subpanel 22 may serve as a front cover of the card body panel 12, placing the cam lift mechanism 16 and the decorative element 18 on the outside of the greeting card assembly 10, with or without a secondary cam lift mechanism inside the greeting card assembly 10. Furthermore, although the technology herein is described in reference to a greeting card, other openable items may incorporate the cam lift mechanism and the decorative element described herein without departing from the scope of this technology. Specifically, the cam lift mechanism 16 allows for rotational motion and/or pop-up extension of two-dimensional and/or three-dimensional decorative paper, cardstock, paperboard, thin cardboard, plastic or the like elements in a greeting card, book, or other pivotally-opened item upon opening thereof. Additionally, the greeting card assembly 10 may also be comprised of other greeting card technology known in the art, such as audio and/or light components (not shown) that turn on when the card body panel 12 is transitioned to the open position and turn off when the card body panel 12 is transitioned back to the closed position. Such technology may be powered by a battery and may be operated by a flexible drive shaft that is fixed to the first subpanel and actuates an on-off switch or circuitry or connects and disconnects an electrical component thereof.
The paper mechanics design of the greeting card assembly 10 allows for rotation and three-dimensional paper pop-up decorative elements while maintaining a thin profile desired for greeting cards and the like. Thus, the greeting card assembly 10 provides a compact product for ease of handling by the user. Furthermore, the greeting card assembly 10 provides a pop-up decorative element that is more stable upon opening compared to prior art designs, due to its ability to move multiple points on the decorative element inward or outward simultaneously to create three-dimensional pop up decorative features, such as a rectangular or square box or a hexagon-shaped birthday cake design.
Various modifications and changes from the illustrated embodiments are within the scope of the present invention. For example, while the described embodiments were illustrated with the card body formed from a single piece of cardstock folded into four subpanels, with the first two subpanels folded and secured together to create the front panel of the card and the last two subpanels folded and secured together to create the back panel of the card, other combinations and configurations can be used.
From the foregoing it will be seen that this invention is one well adapted to attain all ends and objects hereinabove set forth together with the other advantages which are obvious and which are inherent to the structure. It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the invention.
Since many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative of applications of the principles of this invention, and not in a limiting sense.
