Description
Feb. 19, 1963 o. A. BEECK BAND CONTROLLED EXTENSION SLIDE INVENTOR OTTO A. BEECK.
Filed June 22, 1960 United States Patent Office 3,078,129 Patented Feb. 19, 1963 l S,il78,129 BAND CONTRQLLED EXTENMGN SLIDE Gtto A. Beech, 158 Xericho Turnpike, Floral Paris, NIY. Filed lune 22, 1960, Ser. No. 37,895 ll Claim. (Cl. 398- 53) This invention relates generally to extension slides with particular reference to an extension slide which permits of the simultaneous control of the top sections of an extension table so that said sections can be simultaneously opened and closed and otherwise controlled from either end of the table.
This application is a continuation-in-part of United States patent application Serial Number 825,273 filed July 6, 1959, now abandoned.
Although the advantages of an extension table wherein the permanent table top sections are coordinated to move simultaneously are readily apparent, the slides heretofore proposed to effectuate this have not been satisfactory.
When gearing is incorporated in the slide, a rack and pinion for example, the effective length of the slide is reduced by half for all practical purposes. Moreover, with gearing, be it rack and pinion, chain and sprocket and the like, the fine feel of custom wooden furniture is lost. Additionally, gearing presents an unsatisfactory cost picture.
Although a belt and pulley arrangement for obtaining the desired simultaneous control would seem superior to the use of gearing in several important respects, here too existing proposals have been seriously deficient, particularly in the choice of the belt and the arrangement and structure of the component parts of such a system.
It is therefore amongst the primary objects of the present invention to provide a novel belt arrangement in an extension slide by means of which improved results are obtained.
It is another important object of the present invention to provide a simple, highly efficient and smooth operating slide which permits of the simultaneous control of, for example, the movable table top sections of an extension table.
It is yet another important object of the present invention to provide an improved table slide of the above class which retains the traditional feel of a fine Wooden extension table by the elimination of gearing, sprockets, chains and the like.
How these and other objects are accomplished and new results are obtained, will be apparent from what is described in the following specification, particularly pointed out in the claim, and illustrated in the accompanying drawing wherein:
FIG. 1 is a top view of an extension slide in accordance with the present invention, in retracted position,
FIG. 2 is an end view of the slide of FIG. 1,
FIG. 3 is a longitudinal sectional view taken on line 3-3 of FIG. 6, in the direction of the arrows,
FIG. 4 is a transverse sectional view of the upper portion of the slide taken on line 4-4 of FIG. 3, in the direction of the arrows,
FIG. 5 is a sectional view of a portion of the slide taken on line 5-5 of FIG. 3,
FIG. 6 is a top view of the projected slide, partly in section, taken on line 6-6 of FIG. 2, and
FIG. 7 is a longitudinal sectional view of the projected slide taken on line '7-7 of FIG. 2, in the direction of the arrows.
In the drawing wherein a preferred embodiment of the invention is shown, numerals l to 3 designate three juxtapositioned wooden beams forming a slide for use with a table that has two permanent top sections, one of which is attached to slide member 1 and the other to slide member 3, the table in question having one or more supplemental top sections adapted to be laid between the permanent sections when the slide is partly or fully extended. The table and its top sections are not illustrated since it does not form a part of the present invention, being mentioned by way of example rather than limitation.
As has been heretofore stated, it is of advantage to have lateral members 1 and 3 simultaneously controlled and coordinated if this can be accomplished without any impairment in the operation of the slide.
This is accomplished, in accordance with one form of the invention, by longitudinally mounting a band of metallic tape 10 of tempered steel about center member 2, which is longitudinally grooved, as at 15 and 16, to receive the same, and thereafter linking member 1 and 3 to said band to thereby interconnect and coordinate the lateral members. The tension on band 10, when mounted on member 2 as aforesaid, is such that the band may be freely moved around member 2 and yet reliably maintained in position thereon.
Pulleys or roller bodies 4 and 5 are rotatably mounted at the ends of center beam 2 to reduce resistance against the movement of the band. The pulleys may be positioned above or below the aforementioned guide rails. Suitable recesses 4' and 5' are provided at the ends of beam 2 to house the pulleys.
As will be realized, the metallic band is of sufficient flexibility to be readily looped around the roller. The tape material from which the band is made presents a curved cross-sectional profile, which shape is retained after the band is mounted on the slide as may be seen in FIG. 4. By using such a tape, undesired buckling of the band during the operation of the slide is avoided.
The band bearing surfaces of the pulleys, as may be seen in the drawing, are convexed. It has been found that the convexing of the pulleys insures that the metallic band will reliably stay in position thereon. It will be noted that the normally curved metallic band flattens out as it passes around the pulleys and over their convexed bearing surfaces.
In accordance with the present invention, the slide is provided with stops to limit the movement of its lateral components in either direction. In the embodiment shown in the drawing this is carried out by six relatively sturdy, longitudinally aligned pins which extend from the slide members into the interspace therebetween and be yond. Longitudinal grooves 17 and 19, 18' and 20' are provided in the faces of the slide members which form the interspaces into which the aforementioned pins extend so that the pins, by riding in said grooves, will not interfere with the operation of the slide.
Bands in accordance with the present invention are made from strips of the above described metallic tape. An individual band is formed by joining together the ends of a strip by spot welding, riveting as shown at 36' in FIG. 5, or by other suitable means.
Although the invention has been quite thoroughly described, it should be understood that it is not confined to the particular form or use herein shown, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit thereof, and therefore, the right is broadly claimed to employ all equivalent instrumentalities coming within the scope of the appended claim and by means of which the objects of A slide comprising a central support member, slide components slidably aifixed to opposite sides of said central member for movement longitudinally thereof, a roller body mounted at each end of said center member, a flexible metallic band mounted on said rollers for move- References Cited in the file of this patent UNITED STATES PATENTS 1,079,927 Brandner Nov. 25, 1913 1,080,043 Brandner Dec. 2, 1913 1,176,937 Walter Mar. 28, 1916 1,251,257 McKee Dec. 25, 1917 1,299,687 Dabney Apr. 8, 1919 1,939,529 Taylor Dec. 12, 1933 2,068,743 Green Jan. 26, 1937 2,304,843 Nordquist Dec. 15, 1942 2,751,269 Hafeltost June 19, 1956 FOREIGN PATENTS 235,490 Germany Sept. 15, 1908 i eat
