Abstract
A sliding pin is selectively mounted to the back of a poured concrete wall form panel for use in combination with a standard wedge for coupling adjacent panels of the concrete wall form together. The pin when attached to the panel conveniently slides relative to the panel to and between engaged, stowed and retracted positions. Furthermore, the pin is captured within a carrier and is rotatable for convenient access to the slot in the shank of the pin. The components of the system are durable to withstand impact blows by a hammer or other tool, do not require specialized hardware for their use and will not be fouled by splashed concrete or other debris.

A system for releasably coupling adjacent panels to construct a wall form for a poured concrete wall, each of the panels having a marginal frame with holes in the frame so that the holes of the adjacent panels are aligned with one another in the wall form, the system comprising:
- a pin movably mounted to one of the panels proximate each hole;
- wherein the pin is movable between an engaged position in which the pin projects through each of the aligned holes of the adjacent panels, a stowed position and a retracted position;
- wherein the pin further comprises a stem and a shank which are threadably coupled together;
- an enlarged head on one end of the stem;
- a slot extending through the shank transverse to a longitudinal axis of the pin;
- a tapered region on the pin proximate a distal end of the pin which is adapted to project through the holes;
- wherein the tapered region has a length greater than a thickness of the marginal frame of the adjacent panel;
- a carrier having a slide, an impact mast and a casing situated therebetween;
- a bore with an enlarged seat in the casing;
- wherein the pin is housed in the casing with the head being positioned in the enlarged seat, the pin being free to rotate relative to the carrier in the bore;
- a well on a bottom surface of the slide;
- a retainer having a channel formed between spaced channel sidewalls;
- wherein the slide of the carrier is captured by the channel sidewalls for sliding movement in the channel relative to the retainer;
- a stowed detent and an engaged detent on a bottom wall of the channel, the stowed and engaged detents each being adapted to engage the well on the bottom surface of the slide to releasably retain the carrier and the pin in the stowed and engaged positions, respectively;
- a plurality of extensions each of which projects from the retainer and has an aperture there through;
- a base adapted to be mounted to one of the panels proximate the hole;
- a plurality of notches in the base;
- a plurality of fasteners each of which have a head and are adapted to be retained in one of the notches of the base and project through one of the apertures in the retainer to selectively secure the retainer to the base;
- and
- a wedge adapted to be inserted into the slot of the pin when in the engaged position and projecting through the aligned holes in the adjacent panels.

- wherein the pin assembly is movable relative to the mount to and between an engaged position in which a portion of the pin assembly projects through the first hole in the frame and into an aligned hole in the adjacent panel and a stowed position in which the pin assembly is withdrawn from the aligned hole in the adjacent panel for disassembly of the adjacent panels from one another;
- and
- an alternate latching mechanism for coupling the adjacent panels together utilizing the first and aligned holes;
- wherein the pin assembly is also movable to a retracted position which provides access to the first and aligned holes for use of the alternate latching mechanism.
