Description of the Preferred Embodiment For a detailed understanding of the invention, reference is first made to Fig. 1. In this figure there is shown the apparatus according to this invention for permitting, and limiting the extent of, tilting and rotating of a display monitor. The apparatus is made up of a top portion generally designated by reference numeral 1 and a bottom portion generally designated by reference numeral 2. Top portion 1 includes a ring 3 having a flat top 6 and an inside 32. Integral with inside 32 are a plurality of ribs 20, 21, 22, and 23. Ribs 20-23 are in turn integral with, and extend generally radially from, a central hub 24. Yet another rib 17 extends along a diameter of ring 3 and is integral with hub 24. Ribs 17 and 20-23 have lower surfaces 27, 28, 29, 30, an~ 31 which are arcuate in shape extending from ring 3 to hub 24. Surfaces 27-31 form a convex and generally spherically contoured surface which serves as a ball for mating with a socket in bottom portion 2. Rigidity is imparted to top portion 1 by ribs 18 and 19 which extend parallel to rib 17. Rib 18 is integral with ring 3 and ribs 20 and 22. Rib 19 is integral with ring 3 and ribs 21 and 23. The truss type structure thus described has a number of advantages. One is that significant weight is not added to the monitor. Another is that top portion 1 can be molded from an inexpensive polymeric material. Yet another is that, if vent openings are provided in the bottom of the monitor, head dissipation is not restricted.
Extending outwardly and in the same plane as top 6 are wings 4 and 5 having downwardly extending projections 7 and 8.
The lower surfaces 9 and 10 of projections 7 and 8, respectively, are arcuate in shape and will be 1169~;48 described further later herein. Also located in the same plane as top 6 are locating and vent tabs 11, 12, 13, and 14. Tabs 11-14 have openings for communicating with matching openings in the bottom of the display monitor for permitting the dissipation of heat. Also, tabs 11 and 12 have notches ad~acent wing 5 for communicating with lugs (not shown) on the bottom of the monitor for aiding in properly locating top portion 1. In addition, tab 14 has an extension 15 with a locating cutout 16 which further aids in properly locating and mounting top portion 1 on the bottom of the display monitor.
Extending downwardly from hub 24, and integral therewith, is a T-shaped key made up of a leg 26 and a foot 25. The T-shaped key, made up of leg 26 and a foot 25 is for communicating with a lock slot 47 in bottom portion 2. Lock 47 has an enlarged central portion 48 for permitting passage there-through of foot 25 in any rotational position of top portion 1. Lock 47 has radial extensions 71 and 72 of reduced width extending from enlarged portion 48. The width of extensions 71 and 72 is sufficient to permit leg 26 to be freely slidable therein, yet narrow enough to prevent the passage there-through of foot 25.
Lock 47 is located in the bottom of a concavity or crater 46 having a raised lip 44 with a beveled surface 45. The beveled surface 45 can be generally spherically contoured to matingly accept the spherically contoured surface formed by ribs 17 and 20-23 of top portion 1. Thus, surface 45 serves as a socket for top portion 1. Lip 44 is integrally connected at 43 to a plate 41 having a circumferential extremity 42 sufficiently large to be contacted by lower surfaces 9 and 10 for any desired extent of rotation of the monitor. Also, extremity 42 is sufficiently large to be contacted by lower surfaces 9 and 10 for any degree of outward or horizontal extension of wings 4 and 5. Wings 4 and 5 must extend outwardly a sufficient distance to limit vibration should the monitor be disturbed through "bumping", etc. In order that foot 1~ti9648 25 not inkerfere with top 40 of a monitor stand or base, plate 41 is elevated by a footing 50 which is integral with plate 41.
Extending or projecting upwardly from lip 44 is a projection 49 for engaging the facing surfaces of ribs 20 and 22 for limiting the degree of rotation of top portion 1.
For an understanding of the apparatus relative to the display monitor and a stand or base, reference is made to Fig. 2. In this figure is shown display monitor 60 having top portion 1 connected to the bottom thereof. Display monitor 60 includes a screen 61. A base 70 is provided for bottom portion 2 which is mounted on top 40. With top portion 1 connected to the bottom of display monitor 60 such that the center of gravity of display monitor 60 extends through leg 26 and foot 25, very little operator effort is required to position display monitor 60 for convenient viewing of screen 61~
In the embodiment illustrated, bottom portion 2 is to be bonded by suitable means to top 40 of base 70. As a preferred alternative, bottom portion 2 will be molded and be integral with top 40. A preferred alternative to a separate top portion 1 is to have ribs 17-23, the lower portion of ring 3, and downwardly extending projections 7 and 8 of wings 4 and 5 molded into the bottom of monitor 60. The remainder of top portion 1 would then simply form part of the bottom of monitor 60.
Referring next to Figs. 3 and 4, there is shown the relationship of top portion 1 and bottom portion 2 with display monitor 60 tilted in up and down positions.
Illustrated in Fig. 3 are arcuate surfaces 27 and 28, projection 8 of wing 5, foot 25, ring 3, and extension 47.
In Fig. 4, illustrated are projection 49, extension 47, leg 26, foot 25, projection 8, bevel 50, surfaces 29 and 30, and ring 3. It is noted in both Figs. 3 and 4 that leg 26 extends through lock 47 with foot 25 being below the bottom of crater 46. The lower surface 10 of wing 8 is arcuate to permit the tilting of display 1~;9648 monitor 60 and maintain contact with plate 41.
As shown, projection 49, upon an upward tilt of monitor 60, will engage inside 32 of ring 3 and limit the extent of tilt. As an alternative and preferred alternative embodiment, projection 49 will be located within crater 46.
This will permit tilting in either direction to the extent of the outer ends of extensions 71 and 72. The outer ends of extensions 71 and 72 are abutted by leg 26, limiting any further tilting of monitor 60.
Referring to Fig. 5, there is shown, in solid lines, the relationship with the top portion 1 and bottom portion 2 upon rotation of display monitor 60 to the right. The extent of right rotation is limited by projection 49 upon engagement with rib 20. When display monitor 60 is rotated to the left, as shown in dashed lines, projection 49 is engaged by rib 22.
In summary, an apparatus is provided for permitting, and limiting the extent of, tilting and rotating of a display monitor. The apparatus is made up of a top portion to be attached to the bottom of a monitor, and a bottom portion to be attached to the top of a monitor stand. The top and bottom portions are connectable through a key and lock arrangement and have spherical mating contoured surfaces.
The mating contoured surfaces permit the tilting and rotating of the monitor. Located on the contoured surface of the bottom portion is an upwardly projecting lug for engaging the top portion to limit the extent of rotation of the monitor. The key and lock arrangement includes a lock in the bottom portion of a size and shape to communicate with a key in the top portion to control the extent of tilting of the monitor. In addition, the top portion has outwardly and downwardly extending wings for communicating with the top of tha bottom portion for limiting vibration of the monitor.
While the invention has been particularly shown and described with reference to a particular embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made without 36~8 departing from the spirit and scope of the invention.
