The present invention relates generally to work surfaces and, more particularly, to an adjustable height stand and case.
Desk stands are used to provide a work surface at a height above an existing surface, such as a desk or table. The work surface may be used, for example, to support a computer keyboard or a laptop computer. In this manner, a user may stand at the desk while using their keyboard/laptop that is supported by the desk stand at a height above the desk. Some desk stands are adjustable so that the height of the work surface above the desk may be varied.
In a first aspect of the invention, there is a system comprising: a case comprising a first part pivotally connected to a second part, wherein the first part and the second part are configurable in a first case position in which the case is closed, and the first part and the second part are configurable in a second case position in which the case is open; an adjustable stand connected to an interior of the case, the adjustable stand comprising: a bottom frame connected to the case; a top frame connected to the bottom frame via at least one height adjustment system; and a platform connected to the top frame. The platform is rotatable relative to the top frame such that the platform can be positioned at one of plural predefined tilt-angles relative to the top frame. The height adjustment system permits the top frame to be moved vertically relative to the bottom frame to position the top frame at one of plural predefined heights relative to the bottom frame.
In embodiments, the bottom frame is connected to the case by connectors that permit the stand to be selectively connected to, and disconnected from, the case. The case may comprise one of a briefcase and a bag. In implementations, the system is structured and arranged such that: the stand is collapsible to a first stand position in which the stand fits completely inside the case when the case is closed; and the stand is moveable from the first stand position to a second stand position in which the stand extends upward out of the case when the case is open.
In further embodiments, the height adjustment system comprises at least one scissor mechanism that is operatively connected between the bottom frame and the top frame. The system may further comprise a locking mechanism that selectively locks the at least one scissor mechanism at one of plural predefined positions, wherein respective ones of the plural predefined positions correspond to respective ones of the plural predefined heights. In implementations, the locking mechanism comprises an element that, when actuated by a user, unlocks the locking mechanism and permits lowering the top frame relative to the bottom frame.
In still further embodiments, the system comprises: an auxiliary platform; and an attachment system connected to the stand, wherein the attachment system permits the auxiliary platform to be selectively connected to, and disconnected from, the stand. In some implementations, the system is configured such that: a top surface of the auxiliary platform is in a substantially horizontal orientation when the auxiliary platform is connected to the stand via the attachment system; the top surface of the auxiliary platform remains in a substantially horizontal orientation when the top frame is moved vertically relative to the bottom frame; and the top surface of the auxiliary platform remains in a substantially horizontal orientation when the platform is rotated relative to the top frame.
In even further embodiments, the system includes: a platform support pivotally connected to the platform; and plural stops on the top frame. In this embodiment the system is configured such that: the platform support engages a first one of the plural stops when the platform is at a first one of the plural predefined tilt-angles; the platform support engages a second one of the plural stops when the platform is at a second one of the plural predefined tilt-angles; and the platform support does not engage any of the plural stops when the platform is at a third one of the plural predefined tilt-angles.
In another aspect of the invention, there is a system comprising: an adjustable stand configured to be connected to an interior of a case, the adjustable stand comprising: a bottom frame; a top frame connected to the bottom frame via at least one height adjustment system; and a platform connected to the top frame; and plural connectors configured to be connected to an interior of the case. The plural connectors, when connected to the case, are configured to selectively receive and retain the bottom frame of the stand, such that the connectors are structured and arranged to selectively connect the stand to, and disconnect the stand from, the case. The platform is rotatable relative to the top frame such that the platform can be positioned at one of plural predefined tilt-angles relative to the top frame. The height adjustment system permits the top frame to be moved vertically relative to the bottom frame to position the top frame at one of plural predefined heights relative to the bottom frame.
In another aspect of the invention, there is a system comprising: an adjustable stand comprising: a bottom frame; a top frame connected to the bottom frame via at least one height adjustment system; and a platform connected to the top frame; an auxiliary platform; and an attachment system connected to the stand. The attachment system permits the auxiliary platform to be selectively connected to, and disconnected from, the stand. The platform is rotatable relative to the top frame such that the platform can be positioned at one of plural predefined tilt-angles relative to the top frame. The height adjustment system permits the top frame to be moved vertically relative to the bottom frame to position the top frame at one of plural predefined heights relative to the bottom frame. The system is configured such that: a top surface of the auxiliary platform is in a substantially horizontal orientation when the auxiliary platform is connected to the stand via the attachment system; the top surface of the auxiliary platform remains in a substantially horizontal orientation when the top frame is moved vertically relative to the bottom frame; and the top surface of the auxiliary platform remains in a substantially horizontal orientation when the platform is rotated relative to the top frame.
The present invention is described in the detailed description which follows, in reference to the noted plurality of drawings by way of non-limiting examples of exemplary embodiments of the present invention.
The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied in practice.
The present invention relates generally to work surfaces and, more particularly, to an adjustable height stand and case. According to aspects of the invention, an adjustable height stand is selectively connected to the interior of a case. The adjustable height stand is sized to fit inside the case when the adjustable height stand is collapsed to its lowest position. In this manner, the adjustable height stand is configured to be carried in the case while the case is closed, and is configured to be selectively adjusted to different heights when the case is open. In a particular exemplary embodiment, the adjustable height stand is sized to fit inside the case with a laptop computer when the case is closed. In this manner, a user may utilize the case to carry their laptop computer to a location, place the case on a desk or table at the location, open the case, and raise the adjustable height stand, which is supporting the laptop computer, to a height above the desk.
According to aspects of the invention, the adjustable height stand includes a platform that includes a work surface. The work surface may be substantially flat and may be used to support an object such as, for example, a computer keyboard, laptop computer, tablet computer, calculator, pad of paper, etc. In embodiments, the platform is pivotally connected to a frame of the adjustable height stand, such that the platform may be selectively tilted relative to a horizontal plane. In this manner, an object supported on the work surface may be tilted to a location that is most comfortable for the user to interact with the object.
According to aspects of the invention, the adjustable height stand includes an auxiliary platform in addition to the platform that includes the work surface. The auxiliary platform may have a substantially flat upper surface that is configured to be used as a mouse pad. In embodiments, the auxiliary platform is selectively attachable to and detachable from the frame of the adjustable height stand. In this manner, the auxiliary platform may be carried in the closed case with the collapsed adjustable height stand, and may be attached to the adjustable height stand when the case is opened and the platform of the adjustable height stand is raised up out of the case. In embodiments, the auxiliary platform remains static in its position relative to the frame when the platform is tilted relative to the frame. In embodiments, a user may place their laptop on the platform and a mouse device that communicates with the laptop on the auxiliary platform, and the auxiliary platform holding the mouse device remains substantially horizontal when the platform holding the laptop is tilted relative to horizontal. In this manner, the mouse device is supported on a substantially horizontal plane even when the laptop is tilted relative to the horizontal plane. If the auxiliary platform acting as a mouse pad were to tilt with the platform holding the laptop, then the mouse device would be at risk of sliding off the auxiliary platform when the platform holding the laptop is tilted, and implementations of the invention advantageously avoid this undesired situation.
As shown in the figures, the adjustable height stand 10 includes a bottom frame 20, a top frame 30, and at least height adjustment system connected between the bottom frame 20 and the top frame 30. In embodiments the height adjustment system comprises at least one scissor mechanism, although aspects of the invention are not limited to this particular height adjustment mechanism. In a preferred embodiment, there are two scissor mechanisms 40 between the bottom frame 20 and the top frame 30. Each scissor mechanism 40 includes plural linked, foldable supports arranged in a crisscross “X” pattern that permits the top frame 30 to be moved vertically relative to the bottom frame 20.
According to aspects of the invention, the adjustable height stand 10 includes a platform 100 pivotally connected to the top frame 30. The platform 100 includes a top surface 102 and a bottom surface 104. In embodiments, the top surface 102 is configured for use as a work surface, and may be used to support various items including but not limited to: a computer keyboard, laptop computer, tablet computer, calculator, pad of paper, etc. In a particular embodiment, the top surface 102 is substantially flat and includes at least one protuberance 103 near its front edge. In accordance with aspects of the invention, the at least one protuberance 103 is configured to prevent an item resting on the top surface 102 from slipping off the front edge of the platform 100, in particular when the platform 100 is tilted relative to the top frame 30. As described herein, the platform 100 is rotatable relative to the top frame 30 such that the platform 100 can be positioned at one of plural predefined tilt-angles relative to the top frame 30.
With continued reference to
In embodiments, each scissor mechanism 40 comprises four links that are arranged in a stacked, double-X configuration. For example, as shown in the figures, an embodiment of the scissor mechanism 40 comprises links 41 and 42 that are pivotally connected (e.g., by a pin or axle), and links 44 and 45 that are pivotally connected. A top end of link 41 is pivotally connected to a bottom end of link 44, and a top end of link 42 is pivotally connected to a bottom end of link 45. In accordance with aspects of the invention, a bottom end of link 41 is pivotally connected (e.g., by a pin or axle) to one of the bottom side rails 26 in a manner such that the link 41 may rotate relative to the bottom side rail 26 but cannot translate relative to the bottom side rail 26. Similarly, a top end of link 44 is pivotally connected (e.g., by a pin or axle) to one of the top side rails 36 in a manner such that the link 44 may rotate relative to the top side rail 36 but cannot translate relative to the top side rail 36.
According to aspects of the invention, the bottom end of link 42 is connected to the same bottom side rail 26 as is the bottom end of link 41, and is connected in a manner such that the link 42 may rotate relative to the bottom side rail 26 and may translate relative to the bottom side rail 26 in the groove 28 defined by the bottom side rail 26. Similarly, the top end of link 45 is connected to the same to the top side rail 36 as is the top end of link 44, and is connected in a manner such that the link 45 may rotate relative to the top side rail 36 and may translate relative to the top side rail 36 in the groove 38 defined by the top side rail 36.
In embodiments, the link 42 comprises a pin that extends perpendicularly (e.g., horizontally) from the bottom end of the link 42, the pin being arranged inside the groove 28 in the bottom side rail 26. A roller, bushing, slide, bearing or the like is arranged on the pin, and at least partially in the groove 28, to facilitate smooth translational and rotational movement of the bottom end of the link 42 relative to the bottom side rail 26. For example, the pin may have an outside diameter that is smaller than the vertical dimension of the opening of the groove 28, such that the pin extends from the bottom end of the link 42 and through the groove 28 into a hollow interior of the bottom side rail 26. In this example, a plastic slide is arranged on the end of the pin, the slide being inside the hollow interior of the bottom side rail 26 and having a dimension that is larger than the vertical dimension of the opening of the groove 28, such that the pin is maintained in the groove. A similar connection may be used for the top end of the link 45 in the groove 38 of the top side rail 36.
Although only one scissor mechanism 40 has been described, in embodiments both scissor mechanisms 40 may be arranged in a similar manner as described herein, albeit on opposite sides of the bottom frame 20 and the top frame 30. In this manner, a first scissor mechanism 40 is connected between the bottom side rail 26 and the top side rail 36 at a left side of the bottom frame 20 and the top frame 30, and a second scissor mechanism 40 is connected between the bottom side rail 26 and the top side rail 36 at a right side of the bottom frame 20 and the top frame 30.
In accordance with aspects of the invention, and as described herein, the scissor mechanisms 40 permit vertical movement of the top frame 30 relative to the bottom frame 20 while the top frame 30 and the bottom frame 20 each remain horizontal during the vertical movement. When the top frame 30 moves upward (e.g., away from the bottom frame 20), the bottom end of link 41 stays at fixed location relative to the bottom frame 20, and the bottom end of link 42 translates in direction D1 toward the bottom end of the link 41, the translation being along the groove 28 in the bottom side rail 26. Similarly, when the top frame 30 moves upward (e.g., away from the bottom frame 20), the top end of link 44 stays at fixed location relative to the top frame 30, and the top end of link 45 translates in direction D1 toward the top end of the link 44, the translation being along the groove 38 in the top side rail 36. Conversely, when the top frame 30 moves downward (e.g., toward the bottom frame 20), the bottom end of link 41 stays at fixed location relative to the bottom frame 20, and the bottom end of link 42 translates in direction D2 away from the bottom end of the link 41, the translation being along the groove 28 in the bottom side rail 26. Similarly, when the top frame 30 moves downward (e.g., toward the bottom frame 20), the top end of link 44 stays at fixed location relative to the top frame 30, and the top end of link 45 translates in direction D2 away from the top end of the link 44, the translation being along the groove 38 in the top side rail 36.
In a particular embodiment, when the bottom frame 20 is connected to the case bottom 14, the scissor mechanisms 40 permit vertical movement of the top frame 30 relative to the case bottom 14, with the top frame remaining horizontal during this vertical movement. In this manner, the top frame 30 may be selectively raised and lowered relative to the case bottom 14.
According to aspects of the invention, the adjustable height stand 10 includes a locking mechanism that is configured to selectively lock the height of the top frame 30 relative to the bottom frame 20. In embodiments, the locking mechanism locks the height of the top frame 30 at one of a number of predefined locations above a fully collapsed position.
In embodiments, the locking mechanism comprises respective handles 50, each of which is pivotally attached to an outer side of one of the top side rails 36. Each handle 50 includes a number of protrusions 52a-c extending inward from an inner side surface of the handle. The number of protrusions 52a-c defines the number different heights that the top frame 30 can be locked at relative to the bottom frame 20. In embodiments, an outside surface of the top side rail 36 (i.e., opposite the inner side surface that contains the groove 38), has a number of holes 54 corresponding to the number of protrusions 52a-c on the handle 50, with each one of the protrusions 52a-c extending through one of the holes 54 and into the hollow interior of the top side rail 36 when the handle 50 is in a first position relative to the top side rail 36.
In accordance with aspects of the invention, each protrusion 52a-c is configured to prevent translational movement of the slide 47 in direction D2 when the handle 50 is in the first position. In embodiments, each protrusion 52a-c has a flat side 56 and sloped side 58 arranged such that the slide 47 will contact the flat side 56 when the slide 47 is moving in direction D2 and will contact the sloped side 58 when moving in direction D1. The handles 50 are connected to one another by a resilient element 60 that simultaneously urges each of the handles 50 to the first position. The resilient element 60 may comprise a spring that exerts a biasing force on each of the handles 50 that pulls the handles 50 toward one another.

In accordance with aspects of the invention, the rear connectors 70 are fixedly connected to the case 12 and are configured to receive and hold the bottom rear rail 24 such that the bottom rear rail 24 can be selectively connected to, and disconnected from, the case 12. Similarly, the front connectors 80 are fixedly connected to the case 12 and are configured to receive and hold the bottom front rail 22 such that the bottom front rail 22 can be selectively connected to, and disconnected from, the case 12. The rear connectors 70 and front connectors 80 may be connected to the case 12 in any conventional or later developed method, including but not limited to: mechanical fasteners (e.g., screws, bolts, rivets, etc.), adhesive, weld, sewing, etc. Alternatively to be connected to the case 12, the rear connectors 70 and/or the front connectors 80 may be integrally formed with the case 12, such as by forming the case 12 and the rear connectors 70 and/or the front connectors 80 together in a molding process (e.g., plastic molding).
As shown in
In accordance with aspects of the invention, the front connectors 80 are spaced apart from the rear connectors 70 by a dimension that corresponds to a dimension between the bottom front rail 22 and the bottom rear rail 24 of the adjustable height stand 10. By spacing the front connectors 80 apart from the rear connectors 70 in this manner, the latch 82 and keeper 84 of a respective front connector 80 are aligned with one another when the bottom rear rail 24 is inserted into the rear connectors 70 and the bottom front rail 22 is placed on the interior surface of the bottom of the case 12. In this manner, a user may connect the adjustable height stand 10 to the case 12 by first sliding the bottom rear rail 24 into the rear connectors 70 and then engaging the latch 82 with the keeper 84 at each of the front connectors 80.

Moreover, since the auxiliary platform 112 is connected to the top frame 30 via the attachment system 110, the auxiliary platform 112 raises and lowers with the top frame 30 when the top frame 30 is raised and/or lowered relative to the bottom frame 20. Furthermore, the top surface 114 of the auxiliary platform 112 remains in a substantially horizontal orientation when the auxiliary platform 112 is raised and lowered with the top frame 30 relative to the bottom frame 20. Even further, since the auxiliary platform 112 is connected to the top frame 30 (and is not connected to the platform 100), the top surface 114 of the auxiliary platform 112 remains in a substantially horizontal orientation when the platform 100 is tilted relative to the top frame 36. In this manner, the tilt angle of the platform 100 may be adjusted (e.g., as described with respect to
