Description
United States Patent O 3,288,912 CARPETS WIRED FOR SOUND Ray W. Hussey, 1335 N. McCadden Place, Los Angeles, Calif. Filed Sept. 17, 1964, Ser. No. 397,341 7 Claims. (Cl. 174-70) In the making of carpets, both room size and wall-towall types, audio wires can be included into the structure of the material. This creates problems in laying of the carpeting and accessibility of attaching lead wires to connect, for example, a radio on one side of the room to speaker lfacilities on the other side of the room.
Carpeting is usually bordered by pieces of furniture around-the outer edges, but in many cases it is desirable to place a ltable near the center of the room, supporting a phonograph or radio.
Referring to the drawing, FIGURE l illustrates the bottom side of a carpet or carpet element with dotted lines indicating one pattern of ,single undulating-form audio-signal wires therein when in initial position with the end portions of ysuch wires substantially flush with edges of the carpet section. FIGURE 2 is an enlarged fragmentary view of the upper right-hand corner of the carpet element of FIGURE 1 but shown with paired wires and with the end portions of each wire stretched to extend beyond the corresponding edge to provide terminal portions connect'able to an audio component, by which arrangement audio-frequency signals can be transmitted from end to end of a wire, e.g. as when one terminal portion of each wire is connected to a remote speaker or signal-receiving unit and the opposed terminal portion connected to a radio, phonographic equipment, high 'lidelity equipment, or other audio-signal-generating unit producing an audio signal.
The invention involves placing wires in carpeting material at regular intervals with three-foot intervals being preferred. In FIGURE l, the numerals 1 and 2 represent wiring, indicated by the dotted lines, extending in each of two directions; the numeral 3 denoting the carpet as seen from the bottom side; the numeral 4 indicating cross-over zones for the wires. A 3-foot interval is desirable to afford easyarrangement of audio equipment.
In appreciation of the problems faced by carpet-laying workmen, the small copper wires 1 and 2 will be readily cut in the trimming of wall-to-W-all carpeting. Splicing or sewing together of carpeting will require the matching up of the wire pattern before sewing and the soldering of the wires to achieve continuity. Carpet stretching will not adversely `affect the wiring due to the use of flexible or stretchable wires to be described.
Visualizing FIGURE l as the underneath side of a carpet 1l x l5 feet in size, there are four points on each edge available for 'wire connections. These may be attached to radio, phonographic equipment or high fidelity equipment placed at one or more points in the room. It is quite desirable to position the -speaker cabinets across the room in more available space. This permits the operator of the instruments to rest near the equipment, to be available Ifor tuning adjustments or record changing, and remain a beneficial distance for effective stereophonic reception of the separated speakers sounding from across the room.
Other than domestic use, business offices would use carpets wired for sound for their intercoms or entrance alarms; hotels can use the convenience for public address systems; and recording studios, of course, for their work. Piped-in miusic of business establishments would find great benefits in the readily installed wiring of the carpeting.
The task of splicing onto the wire leads can be greatly helped by installation of wire that has a slight wave Patented Nov. 29, 1966 crimped int-o the length to make it stretchable upon application of va longitudinal force. In FIGURE 2 the numeral 5 indicates a rectangular portion of carpeting. The numerals 1 and 2 represent the pairs of wires going in perpendicular directions. Due to the physical appearance and the pliant nature of this design of wiring for this particular use it will herein be called flexible or stretchable wire. To splice into a selected place at the ed-ge of the carpet wired for sound, the ends of the wires are pulled Iwith a pair of pliers. The pull straightens out the waves in the wires in end portions 1a and 2a thereof and extends the length to an inch -or so as to provide terminal portions 1b `and 2b as shown in FIGURE 2. In FIGURE 2. the numeral 2a is applied to the pulled or unflexed wires.
The above disclosure of the particular wire design in the fabrication of carpets wired for sound (that is, the flexible or stretchable wire, which gives the easy splicing feature) is the keynote for the success of the invention. Without this feature, a carpet-layer would not be able to stretch carpeting for wrall-to-wall installation without difculties.
When placing more centrally located furniture in a room, the location of the wires on the bottom of the carpet becomes important. No problem would present itself in the placement of furniture was pre-planned prior to the laying of the carpet. However, the decision after the carpet is laid f-or a table to be placed several feet from the lwall to support equipment that is to be hooked up to the other components calls for special gui-des to iind the wiring hidden on the lower side of the carpeting. These guides or indicia `are needed to show exactly where to make an incision for splicing into the wiring layout. Helpful guides of coloriful yarn strands, not shown, can be needled through the carpeting at the bisecting wire points or cross-over zones 4 and `sheared off at a slightly higher level than the carpet surface. It is contemplated that each bisecting point or cross-over zone shown at the intersection of the dotted llines shall be so marked. This also would give the carpets wired for sound an individual appearance, a feature of this signicance of being a carpet wired for sound.
A transistorized tape recorder, for instance, could be connected to amplifiers and speakers by making a small incision at the appropriate point indicated by the strand of yarn, pulling through a short lead of wires, `and splicing on directly or attaching a jack plug. A microphone could similarly be located, in each case eliminating the dangerous and unsightly use of extension cables lying on top of the carpeting.
In conclusion, carpets wired for sound offer benets to a great number of applications in expediting the needs of today and those anticipated Ifor the future.
