Abstract
There is described a device for holding flat objects, especially printed circuit boards during their being transported or stored, or being conveyed on an assembling line. The device consists basically of a partly or wholly hollow tray having slits in its upper surface which communicate with the hollows. One or more elongated bodies are insertable into the hollow. Cam members are provided urging the inserted elongated members inwardly of the hollows. The boards are placed on edge in the slits and come to rest on the inserted elongated bodies.
Claims16
A device for holding boards, such as printed circuit boards, or other flat bodies, comprising:
- a tray including a pair of tubular members and means interconnecting said tubular members in laterally spaced parallel relationship, each said tubular member having plural laterally extending slot means each opening upwardly and laterally aligned with a respective slot means in the other tubular member for receiving the lower edge portion of respective board to be held in the device;
- a pair of shifting members respectively inserted in and movable longitudinally in said tubular members, each said shifting member having a top surface and plural laterally extending ridges on the top surface;
- plural resilient means normally interposed longitudinally between respective ones of said ridges and ones of said slot means in said tubular members for resiliently engaging boards received in said slot means to clamp the boards resiliently against back edges of said slot means upon rearward longitudinal shifting of said shifting members in said tubular members, and means for effecting said rearward longitudinal shifting of said shifting members.
A device as set forth 2, wherein said back edge of each slot means has a first surface portion elongated in a vertical direction and offset laterally with respect to the respective resilient means and a second surface portion elongated in a horizontal direction and extending laterally at least partially coextensively with said resilient means.
A device for holding boards, such as printed circuit boards, or other flat bodies, comprising:
- a tray including a hollow interior space and upwardly opening slot means extending laterally across the top surface of said tray for receiving the lower edge portions of boards to be held in the device;
- at least one member inserted in and movable longitudinally in said hollow interior space, said member having a top surface and plural laterally extending ridges on the top surface;
- plural resilient means normally interposed longitudinally between respective ones of said ridges and ones of said slots means for resiliently engaging boards received in said slot means to clamp the boards resiliently against back edges of said slot means upon rearward longitudinally shifting of said member in said tray, and
- means for effecting said rearward longitudinal shifting of said member;
- and
- said back edges of said slot means having at each side of said tray a first surface portion elongated in a vertical direction and offset laterally with respect to said resilient means and a second surface portion elongated in a horizontal direction and laterally offset with respect to said first surface portion.
A device for holding boards, such as printed circuit boards, or other flat bodies, comprising:
- a tray including a hollow interior space and upwardly opening slot means extending laterally across the top surface of said tray for receiving the lower edge portions of boards to be held in the device;
- at least one member inserted in and movable longitudinally in said hollow interior space, said member having a top surface and plural laterally extending ridges on the top surface;
- plural resilient means normally interposed longitudinally between respective ones of said ridges and ones of said slots means for resiliently engaging boards received in said slot means to clamp the boards resiliently against back edges of said slot means upon rearward longitudinal shifting of said member in said tray, and
- means for effecting said rearward longitudinal shifting of said member, said means including cam means rotatable between first and second positions, said cam means in said first position permitting movement of said member to a forward position permitting insertion of boards into said slot means, said cam means in said second position uring said member rearwardly to an engagement position to engage said resilient means against the boards thereby resiliently to clamp the boards against the back edges of said slot means, and said engagement position of said member being the same regardless of the thickness of the boards being clamped.
