- An example buckle 100 of the prior art is illustrated in Figure 1.
- Buckle 100 generally includes a first member or buckle housing 101 and a second member or catch 170.
- a first harness strap is secured to the housing 101 in a manner already known in the art
- a second harness strap is secured to the catch 170 also in a manner already known in the art.
- the catch 170 is releasably latched to the housing 101 in order to releasably connect the two harness straps to one another.
- the housing 101 in this embodiment includes first and second outer plates 111 and 112.
- the first and second outer plates 111 and 112 are made identical to one another for purposes of manufacturing efficiency.
- At least one intermediate plate 130 is sandwiched between the outer plates 111 and 112.
- the outer plates 111 and 112 are made of steel in one embodiment, and further in one embodiment, the at least one intermediate plate 130 is made of nylon plastic.
- Four registration pegs 137 project outward from each side of the intermediate plate(s) 130 and align with respective registration holes 117 in a respective outer plate 111 or 112.
- An elliptical boss 131 may also be provided on each side of the at least one intermediate plate 130 to align with similarly shaped openings 113 in respective outer plates 111 and 112.
- Rivets 123 extend through respective holes 103 in one outer plate 111, then through respective holes 133 in the intermediate plate(s) 130, and then through respective holes 103 in the other outer plate 112.
- the housing 101 includes a buckle slide 140 that is preferably made of steel and has a cylindrical middle portion 144 and flat ends 141.
- the at least one intermediate plate 130 has a central opening 134 that is sized and configured to accommodate the entire slide 140.
- each of the outer plates 111 and 112 has a relatively smaller rectangular opening 114 that is sized and configured to accommodate the middle portion 144 of the slide 140.
- the thickness of the intermediate plate(s) 130 is greater than the thickness of the ends 141, so the ends 141 of the slide 140 are movably retained between the outer plates 111 and 112.
- the slide bar 140 cooperates with the openings 114 in the plates 111 and 112 to retain the end of a harness strap.
- the middle portion 144 may be knurled to increase friction between the bar 140 and the strap.
- the at least one intermediate plate 130 also has opposing slots 136 that are sized and configured to accommodate respective springs 160 (or biasing members) between the outer plates 111 and 112.

- Rivets 122 extend through respective holes 102 in one outer plate 111, then through respective holes 152 in respective pawls 158 and 159, and then through respective holes 102 in the other outer plate 112.
- the pawls 158 and 159 are preferably made of steel and sized to be thinner than the intermediate plate(s) 130. As a result, the pawls 158 and 159 are pivotally mounted between the outer plates 111 and 112.
- the pawls 158 and 159 have respective latching portions (or engaging portions) that are biased toward one another by respective springs 160. This inward pivoting of the pawls 158 and 159 is limited by contact between the pawls 158 and 159 and respective portions of the intermediate plate(s) 130.
- the pawls 158 and 159 also have respective force receiving portions (or manipulation portions) that project away from one another and outward beyond the perimeter of the outer plates 111 and 112. These manipulation portions or "wings" define bearing surfaces that face away from the catch 170 and in divergent fashion relative to one another.
- the housing 101 has a receiving end 107 that is sized and configured to receive the catch 170.
- a lead end 171 of the catch 170 is configured for insertion into the housing 101 and between the pawls 158 and 159. More specifically, this lead end 171 of the catch 170 may be described as generally T-shaped, with recessed edges or shoulders 175 on opposite sides thereof.
- the end 171 As the end 171 is inserted into the housing 101, it pushes the latching portions of the pawls 158 and 159 away from one another.
- the pawls 158 and 159 encounter the recessed edges 175 of the catch 170 and snap back toward one another (and behind the forwardmost portion of the catch 170).
- inspection openings or windows 1 19 in the outer plates 111 and 112 allow a person to visually confirm that the pawls 158 and 159 have snapped into engagement with the catch 170.
- the catch 170 cannot thereafter by removed from the housing 101 unless both pawls 158 and 159 are rotated to respective "releasing" orientations.
- An opposite end of the catch 170 is provided with a slot 177 for purposes of retaining the end of a harness strap.
- FIG. 5 illustrates another example buckle 200 of the prior art.
- Buckle 200 includes an identical catch 170 that is selectively latched between similar pawls 258 and 259 on an alternative housing 201.
- the housing 201 similarly includes at least one intermediate plate secured between first and second outer plates by means of rivets 222 and 223 (and registration pegs 237). Both the pawls 258 and 259 and a slide bar 240 are movably retained between the outer plates.
- Each of the outer plates on the housing 201 has an end opposite the catch 170 that is bounded by a concave edge, thereby defining a notch.
- the at least one intermediate plate has a "grippable" portion or tab 232 that spans the notch, and opposite facing sides of the tab 232 are bounded by an arcuate, peripheral ridge 231 that facilitates grasping of the housing 101.
- a "grippable" portion or tab 232 that spans the notch, and opposite facing sides of the tab 232 are bounded by an arcuate, peripheral ridge 231 that facilitates grasping of the housing 101.
