Ratchet stand device

摘要

A ratchet stand device includes a base joined to a top member such that congruently aligned openings, allow a post having a plurality of locking teeth on one side wall to be snugly inserted through the aligned openings. A ratchet part is pivotally disposed in a side aperture of the top member. The ratchet member may be released, whereupon, a spring urges the ratchet part back to forcibly engage one of the teeth of the post member. The first position of the ratchet member is safely maintained via a locking rod. The selected position for the post member is maintained irrespective of the weight of an object disposed upon a saddle of the post, until the object is removed and the locking rod is removed.

主权项

1. A ratchet stand device comprising:
a base member having a relatively large bottom portion for engaging a floor, and a relatively smaller top portion with an aperture therethrough; a top member having top and side apertures, said top aperture being vertically aligned with said aperture in said top portion of said base member; a post member having a saddle portion for receiving a support portion of an object that is ultimately supported by said ratchet stand device, said post member having a lower portion configured to snugly insert through said aligned apertures of said top and base members, said post member having a plurality of locking teeth vertically aligned and integrally formed in a first side wall of said post member; a ratchet member disposed in said side aperture of said top member, said ratchet member having an engagement portion for engaging said plurality of teeth of said post member and a pivot portion with an aperture therethrough that ultimately receives a pivot bar that allows said ratchet member to be manually rotated about said pivot bar to ultimately engage or disengage said engagement portion from said plurality of locking teeth of said post member; a release handle integrally joined to a push portion of said ratchet member, said push portion ultimately receiving imparted force from a user's thumb that forcibly urges said push portion such that said engagement portion of said ratchet member disengages from said locking teeth; a locking bolt comprising a shank and a disk configured to insert through a locking aperture in said base member wherein said disk is located at a distal end of said locking bolt and said disk engages a bias spring limiting movement of said ratchet member and said locking teeth of said post member after said saddle portion engages the support portion of the object, thereby preventing said post member from slipping downward with the support portion thereupon; and the bias spring having an upper end connected to a lower end of said ratchet member, said bias spring having a lower end connected to said base member such that said bias spring is under constant tension irrespective of the position of said ratchet member, said bias spring maintaining the position of said ratchet member until said ratchet member is rotationally urged via said post member and/or via a user pushing upon said release handle, whereupon, said post member is vertically positioned to promote engagement between said saddle portion and the support portion of the object to be elevated above the floor, said post member being locked in place via said locking teeth with said locking bolt's disk preventing downward slippage of said post member, whereby said device safely maintains the elevated position of the object above the floor until said locking bolt is released and said release handle of said ratchet member depressed to allow said post member to be lowered into said base member.
