Two-stage quick release interconnect and locking device
View Patent ↗A quick release interconnect and locking device having a base plate with a post A circular and planar D-shaped disc is disposed on an end of the post. The apparatus has a female element with a contoured channel. A keeper plate with a vertical slot is placed over the contoured channel. A medial portion of the contoured channel includes an upper locking face terminating at a lower end in radius, such that when the D-disc is aligned parallel with the upper locking face, the D-disc may be translated downwardly until it encounters a locking portion, where it may again be rotated to bring the sliding face into alignment with a locking face and may then be translated downwardly to a semi-circular portion at the bottom of the contoured channel, where it may be rotated to lock it in the lower locking portion.
1. A quick release interconnect and locking device, comprising:
a male element having a base plate with at least one substantially planar side, a post having a proximal end attached to said base plate such that said post is generally normal to said planar side, a generally circular planar D-disc disposed on a distal end of said post, said D-disc having a diameter greater than said post and a generally flat sliding face defined by a cord truncating a portion of said circular planar plate;
a female element having a contoured channel with an upper portion, a medial portion, and a lower locking portion, and retention means disposed over said channel and having a longitudinally disposed slot for retaining said D-disc in said contoured channel while also allowing slidable insertion of said post and said D-disc into said contoured channel from said upper portion to said lower locking portion;
means for connecting either of said male element or said female element to an article; and
wherein said medial portion of said contoured channel includes a right side and a left side, said left side having a substantially straight upper locking face that terminates at a lower end in an outward radius, such that when said sliding face of said D-disc is aligned generally parallel with said upper locking face, said D-disc may be translated downwardly into said contoured channel until said sliding face fully passes by said upper locking face, and after passing said upper locking face said D-disc may be freely rotated within said medial portion of said contoured channel.
2. The apparatus of claim 1 , wherein said lower locking portion includes a right side and a left side, said right side including a substantially straight lower locking face that terminates at a lower end in an outward radius, such that when said sliding face of said D-disc is aligned generally parallel with said lower locking face, said D-disc may be translated downwardly into the lower locking portion of said contoured channel until said sliding face fully passes by said lower locking face, and after passing said lower locking face said D-disc may be freely rotated within said lower locking portion of said contoured channel so as to allow selection locking or selective release of said D-disc from said lower locking portion.
