Abstract A panel fastener for rigidly interengaging two members so that the resultant assembly contains a substantially flush exposed surface. Each of the members contains a row of holes adapted to be aligned with a row of holes in the other member. One of the members has an engaging surface for contact with the other member and has a receptacle portion extending therefrom. A row of cups is in the receptacle portion with every other cup in communication with a hole in the one member. A longitudinal pin is shiftably mounted in the one member and extends through the cups. A biasing element is in each cup not aligned with a hole and is retained in position by engagement with the pin. A stud element is adapted to extend through the aligned openings in the members and has a cam slot adapted to engage with the pin. Finally, the stud element is extendable entirely within the members from one side thereof so as to provide an exposed flush surface and is rotatable between an open and closed position so that when the stud is rotated to the closed position the pin will follow the cam slot and will bias the biasing element in each adjacent cup to retain the pin in the closed position and the members in rigid interengagement.
A panel fastener for rigidly interengaging two members so that the resultant assembly contains a substantially flush exposed surface comprising: each of the members containing a row of holes adapted to be aligned with a row of holes in the other member; one of the members having an engaging surface for contact with the other member and having a receptacle portion extending therefrom; a row of cups in the receptacle portion with every other cup in communication with a hole in the one member; a longitudinal pin shiftably mounted in the one member and extending through the cups; a biasing element in each cup not aligned with a hole and retained in position by engagement with the pin; a stud element adapted to extend through the aligned openings in the members and having a cam slot adapted to engage with the pin; and the stud element being extendable entirely within the members from one side thereof so as to provide an exposed flush surface and being rotatable between an open and a closed position so that when the stud is rotated to the closed position, the pin will follow the cam slot and will bias the biasing element in each adjacent cup to retain the pin in the closed position and the members in rigid interengagement.

A panel fastener for rigidly interengaging two members so that the resultant assembly contains a substantially flush exposed surface comprising: each of the members containing a row of holes adapted to be aligned with a row of holes in the other member; one of the members having an engaging surface for contact with the other member and having a receptacle portion extending therefrom; a row of cups in the receptacle portion with every other cup in communication with a hole in the one member; a longitudinal pin shiftably mounted in the one member and extending through the cups; a biasing element in each cup not aligned with a hole and retained in position by engagement with the pin; a stud element adapted to extend through the aligned openings in the members and having a cam slot adapted to engage with the pin; and the stud element being extendable entirely within the members from one side thereof so as to provide an exposed flush surface and being rotatable between an open and a closed position so that when the stud is rotated to the closed position, the pin will follow the cam slot and will bias the biasing element in each adjacent cup to retain the pin in the closed position and the members in rigid interengagement.
Claim 3
Dependent Claim
16 words
The invention in accordance with claim 1 wherein the biasing member is a helical compression spring.
Claim 4
Dependent Claim
79 words
The invention in accordance with claim 1 wherein each cup contains a pair of opposed slots with each slot in communication with the adjacent slot of the next cup so as to provide a continuous through passage in the receptacle portion, each slot being vertical so that when the pin is extended therethrough it can be vertically reciprocated so as to bias and release the biasing member in response to engagement with the cam slot in the stud element.
Claim 5
Dependent Claim
64 words
The invention in accordance with claim 1 wherein the rim of the end of the stud opposite the end containing the cam slot has a beveled surface and each hole in the other member has a corresponding beveled surface so that when the stud is inserted through the members the beveled surfaces will mate to thereby provide a flush exposed surface for the assembly.
