Title: Quick release seat support

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     This device relates to chair and seat supports that provide an upstanding single post to support a fixed or rotatable seat thereon. In certain environments a seat is required to be affixed to its point of use and yet be easily removable for cleaning and/or repair of the mechanisms to which it is attached. 
     2. Description of Prior Art 
     Prior Art devices of this type have relied on a variety of different support configurations to space and secure a seat in relation to a special location, such as a service counter. See for example U.S. Pat. Nos. 317,254, 877,837, 1,254,969 and 3,350,151. 
     In U.S. Pat. No. 317,254 a stool for tables is disclosed having a vertically adjustable stool pivotally attached to a post depending from the underside of a table. 
     U.S. Pat. No. 877,837 discloses a sewing machine attachment wherein a hair on rollers can be moved towards and away from a sewing machine on a pair of spaced parallel elongated tracks. 
     U.S. Pat. No. 1,254,969 discloses a reading table having a chair supported by an arm extending to the table and adjustably secured thereto. The chair can be moved towards and away from the table. 
     Finally, in U.S. Pat. No. 3,350,151 a counter structure is disclosed having an arcuate counter portion with a plurality of spaced attached stools secured thereto. Each stool has a pair of leg extensions that extend to and are permanently secured to the counter. 
     SUMMARY OF THE INVENTION 
     A removable seat support to temporarily secure and attach a seat to a fixed location. The device allows for quick and easy removal of the seat so as to be repositioned to another location or resecured to its original location. The device is of a onepiece support member having an upstanding seat engageable on a post and a quick release configuration on the free end for registerable attachment with the point to which it is secured. 
    
    
     DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is a side plan view of the device in use; 
     FIG. 2 is an enlarged broken away portion of the point of attachment of the device; 
     FIG. 3 is a section on lines 3--3 of FIG. 1; and 
     FIG. 4 is a multiple composite view illustrating the required chair positions to disengage and remove the device from the secured position. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A quick release seat support 10 has a seat configuration 11 secured thereto comprising a post 12 having a support base 13. A seat frame 14 is mounted to the free end of said post 12 with a seat cushion 15 positioned thereon. A back support 16 is formed from an upstanding portion of the seat frame 14 and has a back cushion 17 secured thereto facing said seat cushion 15 as will be well known and understood by those skilled in the art. The quick release seat support 10 comprises an elongated generally flat body member 18 having the support base 13 secured inwardly of one end and a curved upstanding quick release fitting 19 on the oppositely disposed end thereof. 
     Referring now to FIGS. 3 and 4 of the drawings the quick release fitting 19 can be seen in greater detail comprising a compound curve 20 with a foreshortened vertically aligned registration portion 21 extending therefrom. The inverted generally u-shaped channel member 22 is secured to a machine base 23 and comprises in cross-section a vertically ascending engagement leg 24 having a right angularly extending flange portion 25 with a down-turned angularly inclined descending portion 26. An out-turned guide flange 27 is formed on the end of said descending portion 26 defining an inward facing convex resilient engagement surface at 28. The overall cross-sectional shape of said channel member 22 defines an area of reduced transverse dimension between said engagement leg 24 and said engagement surface 28. 
     In operation the machine base 23 has a machine M secured or integral with said machine base 23. The quick release seat support 10 and its attached seat configuration 11 are secured thereto as best seen in solid lines in FIGS. 1, 2 and 4 of the drawings. To remove the quick release seat support 10, the seat configuration 11 is lifted vertically as illustrated in FIG. 4B and in broken lines B in FIG. 2. As the base 18 moves upwardly with the seat configuration 11, the registration portion 21 of the quick release fitting 19 moves downwardly within the u-shaped channel member 22 flexing the descending portion 26 of the channel. 
     Referring now to FIGS. 2 and 4C of the drawings the chair configuration 11 is fully raised allowing for clearance of the registration portion 21 within the u-shaped channel 22 and removal of the quick release seat support 10. The descending portion 26 returns to its original shape. 
     For reinsertion of the quick release seat support 10 the above described steps are reversed whereby the seat configuration 11 is raised as seen in FIG. 4C and the quick release fitting 19 is engaged within the u-shaped channel member 22 deflecting the descending portion 26 as in FIGS. 2 and 4B with the final registration and alignment following as seen in FIGS. 2 and 4A. 
     It will be evident that installed in environments that require periodic access to the machine base 23, such as casinos and the like, the ease of removal of the quick release seat support 10 is of a very desirous nature reducing machine down time and associated profits. 
     Thus, it will be seen that a new and useful quick release seat support has been illustrated and described and that various changes and modifications may be made therein without departing from the spirit of the invention, therefore I claim:
