DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

(13) Referring now to FIG. 1 we see a perspective view of the embodiment 100. The embodiment 100 is being viewed from the underside as it is mounted to the ceiling of a room such as a bedroom, above a bed. The main housing 6 holds electro-mechanical elements as will be discussed below and is covered by a platform member 2 that can be raised or lowered as will be explained below. Screw covers 70, 72, 74, 76 conceal anchor screws that hold the main housing to the ceiling. Nut 4 holds an adjustable electronic device holder in place on the opposite side of panel 2.

(14) FIG. 2 is a perspective view of the embodiment hanging from a ceiling and showing a platform 2 lowered from the main housing 6 via cables 12, 14, 16, 18. An adjustable device holding mechanism 10 can be expanded or contracted via a spring mechanism to hold electronic devices of various sizes. This type of device holding mechanism is known and commonly used in a variety of device holding products. The rear two cables 14, 16 can be independently adjusted by the user, using a remote handheld device to cause the device 8 such as a tablet to be tilted at an angle for easy viewing.

(15) FIG. 3 shows a similar view as shown in FIG. 2 however the device holding assembly 10 has been fastened to the underside of platform 2 allowing the electronic device 8 to be suspended directly above a person's head while the person is lying in a prone position in bed.

(16) FIG. 4 is a partial exploded view showing the device holder assembly 10 holding an electronic device 8 and about to be installed on platform 2 by having threaded post 11 penetrate aperture 5 and secured by nut 4. The electronic holding device 10 can be attached to the top surface of panel 2 or the bottom surface of platform 2 depending on how the user intends to use the invention 100.

(17) FIG. 5 is an exploded view of the embodiment showing main housing 6, cosmetic cover 20, gear motors 22, 24, shafts 26, 28, platform 2, and other components used in the embodiment 100 which will be described in detail in the following FIGS. 6, 7, 8, 9.

(18) FIG. 6 is a perspective view of the working components of the embodiment with main housing 6 removed and pully covers 40 lifted off to reveal pulleys 32, 34, 36, 38 which each contain rolled cables 12, 14, 16, 18 as shown in FIG. 2. Pulley covers 40 keep the cables from jumping off the pulleys during use. The cables exit through slits 54 in pulley covers 40. Gear motors 22, 24 each have double shafts which extend from either side of the gear motor 24, 22. The right-side shaft of gear motor 24 causes the right-side pulley 38 to rotate and the left side shaft of gear motor 24 causes extended shaft 28 and attached pulley 32 to rotate. Therefore, both pulleys 32, 38 turn at the same rate and cause the cables 16, 18 to extend or retract at the same rate. The same holds true for pulleys 34, 36 which are driven by gear motor 22. It should be noted that in one embodiment, only three cables can be used, two in the front of platform 2 and one centrally located in the back of platform 2. Cable 98 connects the power supply 30 with electronic assembly 42. Cable 92 connects cable 18 to electrical assembly 42. Additional cables extend from each rolled up cable assembly 32, 34, 36, but are not shown for clarity purposes.

(19) FIG. 7 is an exploded view of the mechanical drive components of the embodiment 100. Gear motor 24 has a right-side shaft 44 which engages connector piece 46. The opposite side of connector 46 engages pulley 38. The right side of pulley 38 comprises means for delivering electric power to the device holding platform, is hollow and can accept rotary electrical connector 43 which terminates on its right side in stationary shaft 41. The rotary connector 43 allows one electrical cable 80 to be connected to cable 18 which is rolled up on pulley 38 and the other electrical cable 82 to go to battery power supply 30 shown in FIG. 9. Encoder disk 48 is attached to shaft 28. As magnet on the encoder disk 48 passes by sensor 50, it registers as one revolution in a microprocessor within electrical assembly 42 shown in FIG. 9. In this way, the amount of cable unspooled or spooled onto the pulley 38 can be monitored and used to remember the preferred amount of drop of platform 2.

(20) FIG. 8 is a partial section view of the embodiment 100. Panel 2 is supported by four cables 12, 14, 16, 18 one of which 18 is shown in this section view. Gear motor shows its double shaft configuration, one side of which rotates pulley 38 and the other side of which rotates shaft 28. Rubber eyelet 56 creates a slight frictional force to ensure that the cable 18 remains taught as it is being rolled up on pulley 38.

(21) FIG. 9 is a plan view with panel 2 removed. Four apertures 60, 62, 64, 66 allow screws to extend through the apertures and be fastened into a ceiling. An electronics assembly 42 includes a microprocessor that helps control the amount of cable that extends from the main housing 6 by counting the number of revolutions of the shaft 28, as well as a receiver circuit that can receive signals from a handheld transmitter, not shown, to command the platform 2 to lower or raise as needed by the user. DC Battery 30 is rechargeable. At least two of the four cables 12, 14, 16, 18 conduct electricity so that the battery 30 can be recharged via a charging port 90 located on platform 2 and shown in FIG. 10 which can be lowered for easy charging rather than having to plug a charging cable into a port located on the main housing located near the ceiling; electrical cables 94, 96 conduct electricity from the charging port 90 cables 14 and 16.

(22) A three-cable embodiment, not shown in drawings, comprises a single pulley disposed near an axial center of the shaft it is mounted on, while the other shaft is as described herein.

(23) While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.

(24) In the claims upper defines an entity in the direction higher from the ground, while lower defines an entity in the direction closer to the ground. In the claims right defines an entity in the direction along the shaft axis in the direction toward the gearmotors from the axial center of the axis. In the claims left defines an entity in the direction along the shaft axis in the direction away from the gearmotors toward the axial center of the axis.

(25) In the claims the term gear motor is equivalent to gearmotor, as both terms are used interchangeably by those knowledgeable in the art of making and using gearmotors.

(26) In the claims, the word comprising does not exclude the presence of other elements or steps then those listed in a claim. Furthermore, the terms a or an, as used herein, are defined as one, or more than one. Also, the use of introductory phrases such as at least one and one or more in the claims should not be construed to imply that the introduction of another claim element by the indefinite articles a or an limits any particular claim containing such introduced claim element to inventions containing only one such element, even when the same claim includes the introductory phrases one or more or at least one and indefinite articles such as a or an. The same holds true for the use of definite articles. Unless stated otherwise, terms such as first and second are arbitrarily used to distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. The mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to advantage.
