ADJUSTABLE FLOOR AND CEILING SUPPORTED CHINNING BAR This application is a continuation-in-part of my copending application, Ser. No. 668,135, filed Sept. 15, 1967, for the improvement in the Chinning Bar Apparatus, which will now be permitted to lapse without prejudice, in view of its being superseded by this application. Claim 2 in the present application and the Abstract of the Disclosure are common to both applications.
BACKGROUND OF THE INVENTION The present invention relates to the very old chinning bar structures found in schools, public gymnasiums and in the garages of homes. It particularly pertains to the horizontal hand bar adjustably attached to vertical structural members for exercising the human torso. Specifically, the invention is an improvement in the mode and means of construction and installation, being intended to provide a prefabricated knocked-down apparatus that is lightweight, easy to assemble without tools, and capable of being installed almost any place in the home between a floor and ceiling.
Before this invention, it was necessary to custom build a floor supported chinning bar structure and fix it with fasteners to the building where it was to be erected. Until the present invention, it was not known that spring-loaded vertical members bearing against the ceiling could be used to safely support a horizontal bar with a moving load placed upon it because it was not realized that sufficient force could be brought to bear against such ceilings as sheetrock for stabilizing the vertical members. In the analogous art such as pole lamps, pole stands, and other pole structures, none of these accommodate a moving load.
SUMMARY OF INVENTION The invention is comprised substantially of two vertical legs supporting horizontally an adjustable hand bar, the vertical legs with frictional means at extreme ends thereof being supported exclusively by and between a floor and ceiling. The vertical legs .are constructed in two parts, the vertical member being the lower part and the vertical extension member being the upper part. The vertical members are identical or opposite hand, having rectangular tubular cross sections and frictional means at their lower ends for engaging the floor; the frictional means comprising a round bar fitted into a frictional cap and both fitted into each of the vertical members to bear against their inside surfaces with the caps projecting therefrom to engage the floor. At the upper ends of the vertical members, two sets of three holes are longitudinally disposed in pairs on the frontal and rear sides therethrough and coincident therewith. The upper part of the vertical legs, the vertical extension members, extend above the vertical members and have angle cross sections with a number of equally spaced holes therein longitudinally disposed on the frontal faces therethrough and are connected adjustably for longitudinal and lateral engagement to the vertical members by bolt means. The two sets of three holes at the upper ends of the vertical members are spaced such that each pair of holes comprises incremental spacings between two consecutive holes in the vertical extension members, allowing incremental adjustment in the engaged length of the vertical members with the vertical extension members for obtaining the desired length of the vertical legs for fitting to various ceiling heights. A rectangular tube for each of the vertical extension members in connected by bolt means thereto at the upper ends thereof, each tube being engaged longitudinally with the vertical extension members. Each tube contains a helical spring, bearing against the bolt means at its lower end, and frictional means comprised of a round bar with a frictional cap thereon which bears against the spring at its lower end and compresses the spring when the frictional cap at the other end bears against the ceiling.
A round horizontal bar extending across and between the vertical extension members is connected thereto by U-shaped bolt means extending through the equally spaced holes in each vertical extension member to'support each end of the bar, the U-shaped bolt means having wing nuts removably secured to each end thereof so as to allow adjustment of the height of the bar.
DESCRIPTION OF THE INVENTION The preferred embodiment of the invention is illustrated in the drawings in which:
FIG. 1 is a frontal elevation;
FIG. 2, including FIG. 2A, is a broken vertical section, being typical in opposite hand relationship, taken on line 2-2 of FIG. 1;
-FIG. 3 is a typical horizontal section, taken on lines 3-3 and 3A3A of FIG. I; I
FIG. 4 is a horizontal section, being typical in opposite hand relationship, taken on line 4-4 of FIG. 1;
FIG. 5 is a horizontal section, being typical in opposite hand relationship, taken on lines 5-5 and 5A5A of FIG. I.
In the drawings as shown in FIG. 1, the apparatus is comprised substantially of two vertical legs extending between the floor F and the ceiling C with a round horizontal bar 4 connected thereto. The vertical legs are comprised substantially of two parts, the lower part called the vertical members I, and the upper part called the vertical extension members 2. In FIGS. 2, 3, and 5, the vertical members I have rectangular tubular cross sections and are taperingly crimped concavely at their lower ends to seat floor engaging frictional means at said ends, the frictional means being comprised of a round bar 8 fitted into a frictional cap 9, which has a conically shaped exterior surface, such that may be both fitted into the lower end of each vertical member 1 to bear against the inside surfaces thereof with the frictional cap 9 projecting therefrom and thereby engage the floor F. In FIG. 2, at the upper end of the vertical members 1, it will be noted that two sets of three holes designated X1, Y1, Z1, and X2, Y2, 22 are provided for bolts 6 and wingnuts 7.
The upper part of the vertical legs, the vertical extension members 2, which have angle cross sections, extend above the vertical members I and longitudinally and laterally engage therewith on two sides thereof, being connected thereto by bolts 6 and secured by wingnuts 7, as shown in FIG. 2. On the frontal side of the extension members 2, a series of equally spaced holes H are disposed longitudinally in line thereon for the full length thereof, as shown in FIGS. 1, 2, and 2A. These holes H provide a threefold utility, one of which is the longitudinal adjustable bolted engagement of the vertical members I with the vertical extension members 2. Holes X1 and X2, Y1 and Y2, Z1 and 22 in the vertical members I, as indicated in FIG. 2, are employed to incrementally adjust any longitudinal length requirement falling between the equally spaced holes H in the vertical extension members 2 and thereby allowing frictional inch adjustment for varying ceiling heights.
A second utility of the equally spaced holes H in the vertically extension members 2 is shown in FIGS. 2A and 5 wherein the rectangular tubes 3 with holes therein, engage the vertical extension members 2 at their upper ends and are connected by bolts 6 extending through holes H and secured by wing nuts 7. The rectangular tubes 3, together with springs 10 substantially comprise the spring means at the upper ends of the vertical extension members 2. The upper frictional means is comprised of a round bar 8 fitted into a conically shaped frictional cap 9, both of which are fitted into rectangular tube 3 which is taperingly crimped concavely at its upper end to facilitate seating with the bar bearing against spring 10 at its lower end with cap 9 projecting therefrom and engaging the ceiling C thereby.
In FIGS. 1, 2A, and 4, a round horizontal bar 4 extends across and between the vertical extension members 2, each end of which is supported by U-shaped bolts 5 extending through a pair of equally spaced holes H in each vertical extension member 2, the U-shaped bolts 5 having wing nuts 7 removably secured to each end thereof for adjusting the height of horizontal bar 4.
In FIG. 1, the relative lowest position of the horizontal bar (4) is indicated in dashed lines.
