DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
One embodiment of the positionally adjustable support apparatus is shown in FIG. 1. A book support 32 is formed of a flat material such as plastic or plexiglass, rectangular in shape, and bent ninety degrees at one end to form a shelf on which book 30 rests. The pages of the book can be held open by rubber bands 34R and 34L which are fitted into notches near the upper corners of support 32. An alternative embodiment for holding pages open is composed of a ½ round clear acrylic rod 36 to which is affixed an elastic material 38 at each end using glue and short lengths of heat shrink tubing 39R and 39L. In one embodiment, rod 36 can be a ½ round clear acrylic rod and act as a magnifier for one line of reading material.
The book support 32 is attached to a length of flexible metal tubing 40 using swivel bracket 42, and screws 43 and nuts 45, as shown in FIG. 3A and FIG. 4. The proximal end of the flexible metal tubing 40 is attached to a threaded coupling 47. Coupling 47 accepts a first threaded rod 41 whereby threaded rod 41 is affixed to the proximal end of the flexible tubing. Advantageously, the threaded rod 41 is retained to the flexible tube such that it cannot be easily unthreaded. Examples of such connections are well known in the art including use of a thread locking material or a locking nut.
The exposed end of threaded rod 41 is threaded into bracket 42. The book support 32, and bracket 42 to which the book support 32 is affixed, can thus rotate with respect to the flexible tubing 40, but the rotational position can be fixed by tightening adjustment knob 46. Knob 46 is attached to a second threaded rod 49 which is also threaded into bracket 42 through a threaded opening orthogonal to and terminating at the threaded opening accepting the first threaded rod 41. Accordingly, rotating knob 46 in one direction will cause the end of the second rod 49 to physically engage the first threaded rod 41 and set the position of the book support 32 relative to the tubing 40. Rotation of knob 46 will release the friction applied to rod 41 and allow rotation of the book support 32 to a different position with respect to the tubing 40.
The flexibility of tubing 40 provides for substantial positional adjustment of the support 32. An alternative embodiment is shown in FIG. 3B which utilizes this flexibility. In this embodiment, the proximal end of flexible tubing 40 is fixedly attached to the book support by a bracket 55 lacking the swivel and locking feature of bracket 42.
Book support 32 can be constructed in a plurality of sizes to fit the particular reading material, for example, a smaller width support for paper back books and a wider support for magazines. For those embodiments employing a rod as 36 as the book holder, the length of this rod used can be varied to fit the particular width of the support 32. Advantageously, as described above, the support 32 is easily detached from the distal end of tubing. For example, this can be accomplished by simply unscrewing threaded rod 41 from bracket 42 or bracket 55 and substituting a different sized support 32 by screwing the threaded rod into the bracket of the selected support. Alternatively, the bracket 42 or 55 remains attached to the tubing 40 and instead the support 42 is detached from the bracket 42 or 55 and a different sized support 42 attached to the bracket.
By way of specific example, suitable flexible tubing 40 is sold by the Spiral Metal Products Division of Uniprise International, Inc. located in Terryville, Conn. As shown, the tubing 40 can be substantially the same diameter along its entire length between the book support 42 and the distal end 51 of the tubing.
To increase the overall stiffness of the flexible tubing, a solid but flexible rod 98, such as aluminum or copper wire of suitable gauges, can be inserted into the hollow flexible tubing as shown in FIG. 32.
Operation
The positionally adjustable book support can be used in many different situations where hands free reading is desired, or required. The length of flexible tubing 40 can be bent into any number of positions to establish a stable position for the reading material, and once positioned, can be easily re-positioned to accommodate changes in body or head position. One feature of the embodiment shown in FIGS. 1, 6-13 is that the book support 32 does not require any additional support apparatus, e.g., a base, for maintaining the book 30 stable for the reader. Thus, as shown in FIGS. 1, and 6-13, the length of the tubing 40 at its distal end 51 can be easily bent into a coil to form and function as a stable base, with an almost infinite range of positions as shown in FIGS. 6-13. The coiled distal end 51 can, for example, be placed on the floor, ground, beach, table or counter.
In the embodiment of FIGS. 3A and 4, the book support is easily adjusted with respect to the flexible tubing by adjustment knob 46 which, when loosened, allows the book support to be clockwise or counterclockwise rotated, after which knob 46 is then tightened in the new position.
The book support can be advantageously used in conjunction with furniture such as chair, couch, or bed. FIGS. 14, 15, 17 and 18A, 18B and 18C show the distal end 51 of the flexible tubing coiled beneath a cushion 48, or mattress 51, upon which the reader is seated or lying. The weight of the cushion, as well the weight of the person reading, serves to anchor the flexible tubing 40 to provide a stable support for the reading material. In this configuration, the reading material may be held in a comfortable position with respect to the eyes. As shown in FIGS. 18A, and 18B, the book support allows for a reading position in which the book is suspended above the reader's head, a position which is extremely difficult to maintain if using only one's arms because fatigue occurs quickly. A need to hold reading material in such a position of often associated with recuperation in a hospital bed. FIG. 18C illustrates how the flexible tubing 40 allows support 21 to be held in a substantially vertical position to position the book in alignment with the person's eyes when they are reading while lying on one side.
A feature of the invention is that it does not impinge on the individual's freedom of movement in contrast, for example, with a rigid bed tray that hinders movement of the body and legs. Typically, such a rigid based tray must be physically removed from the bed in order for the person to change position or get out of bed. In contrast, the apparatus shown can be easily moved aside when not in use by simply pushing on the support 32 or tubing 40 to bend the flexible tubing so that the book support and the tubing are out of the way, eliminating the need for assembly and un-assembly before and after use.
When anchored under a cushion or mattress as described above, the support 32 can also be positioned horizontally and used as a positionally adjustable table or tray.
The bracket 42, which enables the book support to rotate with respect to the flexible tubing, as well as adjusting the rotational position, may be implemented using other apparatus and methods which allow for connection of the book support to the flexible tubing such that the book support can be rotated with respect to the flexible tubing, and fixed in rotational position. One such alternative method is described below.
The flexible tubing can be covered in various fabrics 64 to change the aesthetics, or the feel of the tubing, as shown in FIGS. 16A, and 16B.
Children can be encouraged to read by providing a book support shaped like an animal, or animal head, as shown in FIGS. 19-24. Animal paws may be affixed to either end of the magnifying rod 36 as shown in FIG. 19.
When the book support is shaped like an animal, the fabric covering 64, covering the flexible tubing 40, can be advantageously various synthetic fur fabrics, such that the flexible tube resembles an animal's tail.
An alternative embodiment of the swivel bracket which allows the book support to rotate with respect to the flexible tubing is shown in FIGS. 33-36. The swivel bracket includes two halves, swivel bracket front half 80, and swivel bracket back half 82. The front half includes holes for mounting the bracket to the book support. The swivel bracket front half is molded such that it can accept the screw from knob assembly 46 which is inserted through the swivel bracket back half. Both the front and back halves of the swivel bracket are molded such that a semicircular v-shape exists, which will accept v-shaped post 84. The v-shaped post 84 is affixed to the flexible tubing using a threaded tube 86, threaded into both the v-shaped post and the threaded end of the flexible tubing. When knob 46 is tightened, the two halves of the swivel bracket are drawn together, creating a friction between the v-shaped bracket halves and the v-shaped post, thus locking the book support in rotational position with respect to the axis of the flexible tube.
An alternative embodiment shown in FIGS. 27-31 provides a positionally adjustable support 92 for an audio or video player device 90. Typical examples of such devices are the popular iPod and iPod Nano. In one embodiment, a sheet of material such as acrylic plastic shown in FIG. 30, is bent, using heat, into the holder 92 shown in FIG. 31. The holder 92 is affixed to a swivel bracket assembly 80, 82, 46, using screws 44R and 44L and nuts 45R and 45L.
The holder 92 is advantageously shaped such that it will hold the audio or video device in a fixed position, but such as to not interfere with viewing of the display screen, using the front mounted controls, or interfere with electrical connections, such as for a headset. It is adjustable in the entire range of positions as have already been described when used with reading material. Because the holder is formed of light gauge plastic, to insert or remove the device 90, simply bend the top of the holder backwards as shown in FIG. 28. When the unbent position, the tabs on the top and bottom of the holder prevent the device 90 from moving up, or down, and the wrap-around sides prevent side-to-side motion, such that the device 90 is held in place.
Other embodiments of the book support 32 and holder 92 can be constructed by injection molding plastic or bending sheets of metal.
The above-described embodiments have one or more of the following features, advantages and aspects:
- Stability is provided using the flexible tube itself, without the need for an additional base or clamping device. Positional adjustment is not limited to a range of a fixed set of angles.
- There is no complicated positioning required in order to start or stop using the device.
- The aesthetic appearance of the bed or furniture is not affected by the adjustable support.
