| 161 | Adjustable shelf | US10232982 | 2002-08-30 | US20030198230A1 | 2003-10-23 | Suzanne DuBarry; Kevin G. Abelbeck |
| A shelf stores items and provides for organized and attractive display with ease of item access. Conforming to a defined physical environment or variable storage space optimally requires the shelf to provide for both vertical and horizontal adjustment. Here this is accomplished by a pair of legs that are telescopic (to reduce size) and can be locked at a height (vertical adjustment) by use of a pawl, pin, screw or other fastener known in the art. The shelf includes a planar surface that is comprised of a shelf portion, which is supported on each distal end by a leg extension. The leg extensions are mounted to the upper area of the legs. The leg extensions are received by the shelf portion, being movably mounted thereto. This allows for horizontal (width) adjustment. An end cover can be used to provide a flat surface that is consistent with the upper surface of the shelf portion. Feet are added to provide a more solid footing, the feet being removable and providing a mounting tab at the end of the legs and a mounting tab receiver at the opposite end of the legs. This allows for multiple shelves to be securely mounted one on the other. | ||||||
| 162 | Pillow mounted book holder | US09478834 | 2000-01-06 | US06270050B1 | 2001-08-07 | David L. Friedrich |
| A pillow carrying book holder includes a frame in the form of a plate within the pillow. The plate supports retraction mechanism which is connected externally of the pillow to a pair of book engaging fingers. The retraction mechanism includes a pair of springs having one end mounted within the pillow and the other end secured to the book engaging fingers. A housing within the pillow encloses the retraction mechanism within the pillow and separated it from filler material within the pillow. The filler material may include freely moveable particulate for conforming the pillow to the shape of the surface on which the pillow is positioned. | ||||||
| 163 | Wall-mounted shelf unit | US638193 | 1991-01-07 | US5097771A | 1992-03-24 | J. Hatcher James, III |
| A shelf unit includes side panels and top and bottom shelves that extend between the side panels. The shelves are coupled to the side panels. The side panels each have plural interior cavities that are open at the rear edges of the side panels. The cavities are adapted to receive wall mounting brackets that project out from a wall. The rear edge of each side panel has a channel for receiving a shelf standard or wall mounting strip. The shelf unit is installed onto a wall by pushing the unit towards the wall, with the brackets being received by the cavities and the mounting strips being received by the channels. When installed, the mounting hardware is concealed from view. Another embodiment utilizes side panels without interior cavities. Instead, the side panels each have a channel along their respective rear edges. Wall standards, having keyhole shaped slots, are received by the channels. Fasteners are located in each channel and are coupled to the side panel. The fasteners have head portions and shank portions that are received by the wall standard slots. | ||||||
| 164 | Stowable support for books and the like | US799394 | 1985-11-19 | US4754945A | 1988-07-05 | Harvey E. Diamond |
| The invention relates to a means for the compact stowing of a folded support, e.g. for books and the like, when not in use, and to the unfolding thereof, to provide a rigid support in any one of a number of possible positions, from the compact stowed position.More particularly, the invention provides a four-way movement of a book support means from an initial compact stowed position wherein the support means and its associated mechanisms all lie essentially in a single plane, to a position wherein the support means can be adjusted four ways: (1) rotationally and (2) vertically about a given horizontal axis, (3) laterally with respect to a given vertical axis, and (4) rotationally with respect to that given vertical axis. | ||||||
| 165 | Book support system | US462904 | 1983-02-01 | US4512603A | 1985-04-23 | Tommy A. Williams |
| A book support system (10) is provided to allow manual holding and reading of book (12) in one hand of a user. The book support system (10) includes a housing (18) having a recess (20) formed therein. The recess (20) is of predetermined contour and is adapted for insert and receipt of the book (12). A releasable constrainment mechanism (56) including orthogonally directed first and second resilient members (58 and 60) are included to constrain the book (12) within the recess (20). The releasable constrainment mechanism (56) is secured to the housing (18) and a tab member (48) is provided in a lower section of the housing (18) to allow the user to hold the book support system (10) in one hand while reading. | ||||||
| 166 | Combined bookrack and book support | US566697 | 1975-04-10 | US4002240A | 1977-01-11 | Edward G. Dorn |
| A metal rod or bar frame configured to provide an elongated base member with opposed laterally directed end members. The base member includes a first surface which, when upwardly directed, is defined by two angularly related planar portions oppositely inclined downward and outward from a central point, the end members projecting vertically upward therefrom in the manner of book ends. The lower surface of the base member parallels the upper surface and, upon an inverting of the device, provides an elevated wide trough for the support of an open book. | ||||||
| 167 | Mechanic's tray assembly | US514116 | 1974-10-11 | US3983821A | 1976-10-05 | Kenneth R. Kearns |
| The present invention relates to a mechanic's tray assembly of the type useful in conjunction with a vehicle service rack. The mechanic's tray assembly includes a first swing arm pivotably mounted about a stationary point and extending therefrom, the first swing arm including a collar fixed to the outer end and adapted to pivotably receive a second swing arm therein. The second swing arm, which is pivotable independently of the first swing arm, extends outwardly from the collar secured to the outer end of the first swing arm and includes a generally flat mechanic's tray fixed to the outer end thereof which is adapted to receive and contain various paraphernalia used by a mechanic or serviceman while working on a vehicle.The mechanic's tray assembly of the present invention is particularly adapted to be used in conjunction with a conventional hydraulic vehicle service rack customarily found in garages and service stations. In such use, the vehicle service rack is preferably provided with two main pivot assemblies, one on each side of the rack. Each pivot assembly is adapted to receive a turned pivot end associated with the first swing arm. In use, the pivot end of first swing arm may be inserted into either main pivot assemblies mounted on the vehicle service rack. Because of the generally central location of each main pivot assembly, the first swing arm of the mechanic's tray assembly may be directed towards various directions and the final position of the tray can be adjusted by pivoting the second swing arm independently of the first swing arm. | ||||||
| 168 | Self-balancing support | US25779272 | 1972-05-30 | US3863882A | 1975-02-04 | HATCHER CONSTANCE BANNISTER |
| A self-balancing support means particularly adapted for holding a book, magazine, newspaper, or the like, to which are attached adjustable and removable bags containing fluent material which may be adjusted to various positions to balance and hold the support at various inclinations to the horizontal, movable biased means provided on the support and releasably engageable with a book, magazine, newspaper, or the like, so that the pages of the book, magazine, or the like may be turned. A modification of the support means provides a configuration thereof better permitting it and the balancing means to rest on portions of the human body with facility, and in desirable position for reading the material supported thereon.

| 169 | Collapsible lapboard structure | US3730077D | 1972-05-12 | US3730077A | 1973-05-01 | SELDEN B |
| A collapsible lapboard structure has a base, a spacer member hingedly joined thereto, and a support member in turn hingedly joined to the spacer member. When the structure is in its erected position the base member and support member extend perpendicularly from one side of the spacer member, and the hinges employed cooperate therewith to maintain that relationship against downward force on the support member. The base member is adapted to rest upon a seat so as to position the support member over the lap of a person seated thereon.
