DESCRIPTION OF THE PREFERRED EMBODIMENTS

This invention comprises a stand for laptop computers. The stand raises the height of the laptop and holds it at a convenient angle. The stand can be free-standing, or can be mounted to a base such as a table, desk, or moveable cart.

The preferred embodiment of the invention is shown in FIGS. 1A-1C. An optional locking mechanism that prevents the laptop computer from being removed from the stand is shown in FIGS. 2A and 2B. The combination of the stand and locking mechanism to accomplish a locking stand system is shown in FIG. 3. An alternative preferred embodiment of the invention is shown in FIG. 4.

Stand 10 comprises angled support member 12 that is held by base 18. Base 18 can be adapted to sit on a horizontal surface or be attached another structure, as further explained below. Overlying retainer member 14 along with member 12 creates a surround that defines a cavity into which the keyboard portion of a laptop computer is placed. Lower support plate 16 provides an area against which the lower (keyboard) portion of the laptop rests. Adjustable auxiliary plate 20, against which the bottom edge of the laptop rests, may be included so that the device can accommodate different size laptops, or to provide additional adjustability. Plate 20 is adjustable to a number of positions relative to member 12 to move the bottom laptop support area up-and-down as desired, using a slot 22 and insertable tab 21 arrangement.

Stand 10 is shown in exploded view in FIG. 1B and rear view in FIG. 1C. Base 18 includes base member 30 with lower surface 31 that may be placed on a table, desk or the like. Alternatively, coupling studs and nuts assembly 51 may project from the bottom of surface 31 to allow the device to be bolted to a mobile cart, desk or the like.

Member 12 is coupled to member 30 through bracket 32 and fasteners 43 that pass through openings 44 and are received in nuts 45. Projecting studs such as studs 39 and 40 pass through cantilevered plate 34 and are held therein with nuts 41 and 42, respectively.

Locking mechanism 60 is shown in FIGS. 2A and 2B and comprises separable members 64 and 66 that can be mechanically coupled together and then prevented from separation by inserting lock 62 in opening 72. Threaded rod 68 with end member 70 passes through an opening in member 66 and threads into an insert that is fastened to member 64. End member 70 can be gripped and rotated, which causes member 64 to pull in toward member 66. This causes C-shaped end brackets 65 and 67 to overlap and releasably couple to opposite sides of the laptop display 84, as shown in FIG. 3. Once lock 62 is inserted, rod 68 cannot be rotated, so locking mechanism 60 cannot be removed from the laptop. A cable (not shown) can be looped through openings in members 64 and 66 and through openings in member 10 (not shown), with the cable ends crimped, to prevent removal of the locking mechanism from the laptop computer. As a result, mechanism 60 prevents the laptop from being removed from stand 10. If stand 10 is fixed to a larger structure, this increases the security of a laptop computer held in the inventive stand. An alternative embodiment of the inventive stand 100 is shown in FIGS. 4A and 4B. Stand 100 has support member 102 with integral side members 104 and 106, having keyboard-overlaying portions 105 and 107, respectively. Portions 105 and 107 overly only a small portion of each side of the laptop keyboard portion. This allows the user to access the keys, mouse control functions, and other functional aspects located on the top side of the keyboard portion, so that the laptop can be used in a normal fashion while being supported by and retained by the inventive stand. Lower integral tabs 108 and 110 support the lowermost edge of the laptop, while overlying upper tab 125 of sliding retaining member 124 lies against or very close to the top edge of the keyboard portion. This arrangement prevents the keyboard portion from being lifted off of member 102 when tab 125 is in place. As explained in more detail below, padlock 128 holds member 124 in place, which effectively locks the laptop in the stand.

Member 122 is coupled to member 124 such that they mount on rear bar 131. This allows tab 125 to be slid left and right relative to the laptop. When the laptop is placed on the stand (as shown in FIG. 5A, tab 125 is slid to the side. It is then slid back in place to the middle. Tab 126 fits through member 124 such that opening 127 of tab 126 is accessible. Padlock 128 is then placed through opening 127, which effectively locks tab 125 in place over the end of the laptop keyboard portion. The laptop is now held by and secured by the stand.

Stand 100 is preferably constructed such that it is pivotable relative to the structure to which it is coupled. In the example shown in FIGS. 5B-5D, this structure is the top portion of a mobile laptop computer stand such as the Z cart available from JACO, Inc. of Franklin, Mass. Pivoting can be accomplished by using continuous torque hinges 144 on fixed member 142, that are coupled to the stand through openings 114 in support member 102. These hinges are preferably arranged such that the laptop is pivotable from an almost vertical position shown in FIG. 5C, to a horizontal position shown in FIG. 5D. This allows both the keyboard portion and the display portion of the laptop to be placed at a desired angle. The cart has inherent height adjustment, which thus accomplishes adjustability of the laptop in four degrees of freedom.

Although specific features of the invention are shown in some drawings and not others, this is for convenience only, as the features can be combined as would be apparent to those skilled in the art, and as the claims set forth the rights granted under the patent. Other combinations of features would be apparent to those skilled in the field and are within the scope of the claims.
