Abstract:
A mounting for poles of jumps in equestrian sport, said mounting comprising:a pole receiver for mounting said pole in a cradling fashion, said pole receiver comprising:a plate with at least two opposing surfaces;a supporting dish disposed on a first of said opposing surfaces; anda plurality of linearly-spaced first bolts fixedly mounted to a second of said opposing surfaces, each of said bolts comprising:a narrower shaft section; anda wider head section; anda generally vertical adapter rail for connecting said pole receiver to a stand, said adapter rail comprising:at least one vertically-extending slot with an open end commencing at one of the vertical ends of said rail, said at least one vertically-extending slot made up of a linearly-disposed series of alternating narrowed and widened segments, said alternating narrowed and widened segments including:a plurality of narrow portions, each with a width substantially equal to that of said shaft section of each of said plurality of linearly-spaced first bolts;a plurality of wide portions, each disposed adjacent at least one of said plurality of narrow portions and with a width at least as great as said head section of each of said plurality of linearly-spaced first bolts, and spaced apart from one another a distance substantially equal to the distance between said plurality of linearly-spaced first bolts;a further narrow portion disposed between one of said plurality of narrow portions and one of said plurality of wide portions, said further narrow portion with a width less than said shaft section of each of said plurality of linearly-spaced first bolts; anda plurality of linearly-spaced second bolts disposed on a side of said adapter rail facing away from said pole receiver and toward said stand, said plurality of linearly-spaced second bolts adapted to fit into a dual closed-end slot disposed on said stand, each of said plurality of linearly-spaced second bolts comprising:a narrower shaft section; anda wider head section;thereby creating, upon insertion of said wider head section of each of said linearly-spaced plurality of first bolts into respective said plurality of wide portions of said at least one vertically-extending slot, and subsequent placement of said shaft section in operative engagement with said further narrow portion of said at least one vertically-extending slot, such that said shaft is only moveable past said further narrow portion by overcoming a predetermined force acting co-linearly with the longitudinal axis of said at least one vertically-extending slot, and upon insertion of said wider head section of at least one second bolt into a portion of said dual closed-end slot of sufficient width to accept said wider head section, and subsequent placement of said plurality of linearly-spaced second bolts in a supportably disposed position relative to said stand, a mounted pole arrangement capable of breaking away from said stand upon application of said pre-determined force.
