Abstract
Disclosed herein is a securing device for plate-like work pieces, comprising a body member and an anchor member, the body member having a first end and a second end, the first end having an engagement portion, a biasing member to basis the body member laterally within a plurality of aligned openings in said work pieces and biasing the engagement portion past the openings, the engagement portion having an operative surface to engage an outer surface on a first outer work piece, the body member including a threadable portion, the anchor member being operable to engage an outer surface on a second outer work piece, the anchor member including a threaded member to engage the threadable portion, the threaded member be rotationally operational to draw the body member toward the anchor member.
Claims12
A method for clamping a grouping of two or more work pieces, each with an opening, with the openings being aligned to form a pathway through the work pieces, the method comprising introducing at one end region of the pathway a body member with an engagement portion extending laterally outwardly therefrom;
- locating a biasing element between the body member and a boundary of the pathway to bias the body member against an opposite boundary of the pathway and in the direction of the engagement portion;
- aligning the engagement portion with an outer surface portion of a first work piece at one edge of the grouping;
- locating an anchor member against a second work piece at an opposite edge of the grouping and adjacent a second opposite end region of the pathway;
- extending a threaded member between the body member and the anchor member;
- threadably engaging the body member and the anchor member via the treaded member;
- rotating the threaded member so to draw the body member toward the anchor member wherein the body member is displaced laterally by the engagement of the biasing member between the anchor portion and the body member such that the engagement portion engages the outer surface portion of the first work piece at the one edge with sufficient force to clamp the work pieces between the engagement portion and the anchor member.
A kit for clamping a group of work pieces together, comprising a body and an anchor member, the body having a first portion of a first diameter and a second portion of a second larger diameter, the body being dimensioned to pass through a path formed by aligned passages in the group of work pieces, a biasing member operable to transfer the first portion laterally within the path to place the second portion in an operative position adjacent a first contact surface on a first outer work piece, the body having a threaded passage, the anchor member being arranged to lie against a second contact surface of a second work piece of the group;
- a plurality of threaded members of varying lengths, each configured to engage the threaded passage and each of the threaded members rotatably operable to draw the body member toward the anchor member, and a set of instructions on a use thereof.
