Automatically adaptable fastening system for wheeled cots and similar devices

A fastening system for securing cots and similar wheeled devices along a substantial planar surface, said fastening system comprising:

• a wheeled device having a support frame;
• spaced apart front and rear hold-down supports depending downwardly from said frame toward said planar surface in use;
• a longitudinal guide track to be mounted upon said substantially planar surface, said track having a front end and a rear end;
• means for receiving said supports along said guide track, said receiving means permitting longitudinal movement of said supports along said track and preventing substantial vertical or lateral movement therebetween;
• locking means associated with said track for securing said support frame at a predetermined longitudinal position along said track, and preventing further longitudinal movement therealong, said locking means comprising a plurality of locking gates spaced along said guide track and designed to lockingly engage only with supports of predetermined structural conformation, whereby each locking gate is selectively lockable only with certain supports to the exclusion of others;
• and
• release means for selectively disengaging said locking means to permit longitudinal movement of said supports along said track.

A fastening system for securing wheeled patient transfer devices along a substantially planar surface, such as the floor of an emergency vehicle, said fastening system comprising:

• a patient transfer device having a support frame;
• spaced apart front and rear hold-down supports depending downwardly from said frame toward said planar surface in use, said hold-down supports each further comprising a retainer having an outwardly extending flange;
• a longitudinal guide track to be attached adjacent said planar surface, said track having top and bottom surfaces and front and rear ends, and a slot formed along said top surface for slidably receiving said supports and permitting longitudinal movement of said supports along said track, and said slot interfacing with said flange of a support received in said track to prevent vertical withdrawal of said support;
• locking means associated with said track for securing said support frame at a predetemrined longitudinal position along said track, said locking means comprising a plurality of locking gates spaced along said guide track and designed to lockingly engage only with supports of predetermined structural conformation, whereby each locking gate is selectively lockable only with certain supports to the exclusion of others;
• and
• release means for selectively disengaging said locking means to permit longitudinal movement of said supports along said track.

A fastening system for cots and similar devices having a support frame to be secured along a substantially planar surface, said fastening system comprising:

• a longitudinal guide track to be mounted upon said substantially planar surface, said track having front and rear ends;
• a pair of spaced apart hold-down supports attached to said support frame to be secured and depending downwardly from said frame toward said planar surface in use, wherein said supports each further comprise a retainer designed to be slidably received by said track;
• means for receiving said supports along said track, said receiving means permitting longitudinal movement of said supports along said track and preventing substantial vertical movement therebetween;
• locking means for securing said support frame at a predetermined longitudinal position along said track and preventing further longitudinal mvoement therealong, said locking means further comprising a plurality of locking gates spaced along said guide track and which receive and selectively lockingly interact with at least one of said supports, said locking gates designed to lockingly engage only with retainers of predetermined structural conformation, whereby said locking gates are selectively lockable only with certain retainers to the exclusino of others;
• and
• release means for selectively disengaging said locking means to permit longitudinal movement of said supports along said track.

A fastening system for cots adn similar devices having a support frame to be secured along a substantially planar surface, said fastening system comprising:

• a longitudinal guide track to be mounted upon said substantially planar surface, said track having front and rear ends;
• a pair of spaced apart supports attached to said support frame to be secured and depending downwardly from said frame toward said planar surface in use;
• means for receiving said supports along said track, said receiving means permitting longitudinal movement of said supports along said track and preventing substantial vertical movement therebetween;
• locking means for securing said support frame at a predetermined longitudinal position along said track and preventing further longitudinal mvoement therealong, said locking means further comprising a plurality of locking gates spaced along said guide track and which receive and selectively interact with said supports, wherein each locking gate is individually engageable with at least one of said supports;
• and
• release means for selectively disengaging said locking means and further comprising means for simultaneously disengaging all of said gates from said supports to enable longitudinal movement of said support frame relative to said track.
