An improved jack for a ground vehicle including a lever operated jacking mechanism substantially encompassing an elongated rack means, a tubular member affixed at one of its ends to said jacking mechanism and telescopically receiving one end of said rack means therein, ground engaging means pivotally secured to the opposite end of the rack means and bracket means including a channel portion receiving therein the end of said tubular member opposite the jacking mechanism. The improvement comprises means for securing the jack in a generally horizontal storage position comprising an elongated rigid rod, means disposed on the jack at a location spaced apart from the bracket means and defining a first opening for receiving one end of the securing rod and non-pivotal means associated with the bracket means and defining a second opening for receiving the opposite end of the securing rod. The second opening is of a generally tubular geometry with the longitudinal axis being fixed in a generally horizontal orientation when the jack is in its storage position.
In a jack for a ground vehicle including a lever operated jacking mechanism substantially encompassing an elongated rack means, a tubular member affixed at one of its ends to said jacking mechanism and telescopically receiving one end of said rack means therein, ground engaging means pivotally secured to the opposite end of said rack means, bracket means including a channel portion receiving therein said end of said tubular member opposite said jacking mechanism, pivot means securing said tubular member to said channel portion, the improvement comprising means for securing said jack in a generally horizontal storage position comprising an elongated rigid rod, means disposed on said jack at a location spaced apart from said bracket means and defining a first opening for receiving one end of said securing rod and nonpivotal means associated with said bracket means and defining a second opening in proximity with said pivot means for receiving the opposite end of said securing rod, said second opening being spaced from said first opening and of a generally tubular geometry with the longitudinal axis thereof being fixedly oriented substantially horizontally when said jack is in its storage position.
In a jack for a ground vehicle including a lever operated jacking mechanism substantially encompassing an elongated rack means, a tubular member affixed at one of its ends to said jacking mechanism and telescopically receiving one end of said rack means therein, ground engaging means pivotally secured to the opposite end of said rack means, the improvement comprising bracket means including a channel portion having a bottom edge and adapted to pivotally receive that end of said tubular member opposite said jacking mechanism, means securing said bracket means to a vehicle, means defining an elongated surface on said channel portion that extends substantially vertically downwardly from said vehicle when said bracket is in position on said vehicle, means pivotally securing said end of said tubular member in said channel portion with one outer edge of said tubular member being juxtaposed to said elongated surface on said channel portion, the distance from the pivot axis to the outer edge of said tubular member being less than the distance from said pivot axis to said surface, and a support ledge fixedly attached to said tubular member whereby when said jack is in a ground engaging position, said support ledge is immediately below and in contact with said bottom edge of said channel portion and said outer edge of said tubular member is in contact with said bottom edge of said channel portion and the longitudinal axis of said tubular member defines an acute angle with the horizontal.
