Abstract: A stable fire retardant mixture for use in a backstop for decelerating and trapping projectiles. The backstop generally includes a support structure having an inclined surface and the stable fire retardant mixture serving as a projectile trapping medium disposed on the inclined surface. The projectile trapping medium is a resilient granular material intimately mixed with a hydrated super absorbent polymer (SAP) gel and additives. Preferably, the support structure is made of a shock absorbing, foamed, fiber-reinforced concrete, such as SACON®. In embodiments, the support structure also includes an enclosure. The additives control alkalinity, chemically stabilize the mixture, prolong life of the mixture, retard mold formation and bacterial growth and prevent leaching of heavy metals.

Abstract: Disclosed is a target block of the dartboard, wherein said target blocks are assembled in the dartboard frame of the circle target blocks with different shapes, which can be replaced individually; the said interior target materials of the target blocks are made of sisals or similar materials. Through the formation mechanism, a predetermined amount of target materials (sisals) are disposed in the bottom of mounting seat applied with the adhesive in advance to joint the sisals and mounting seat as a whole. The target blocks put in the dartboard frame of the target blocks are in the centric circles and the same fan-shaped radial strip, which has two different colors at intervals to distinguish the blocks from each other.

Abstract: A projectile retrieval system includes one or more valves disposed to selectively release projectiles from a bullet stop and containment system. The valves are in pneumatic communication with a tube which utilized a negative air pressure generated by a vacuum to move the projectiles from the valves to a central container. The projectile retrieval system may also include a vacuum extension which enables the same system to retrieve bullets and casings, fragments and other debris on the range.

Abstract: An archery target with a covering layer and a method of making the same. One or more target elements are arranged in at least one stack. The target elements include side edges oriented toward a target face. A polymeric covering layer extends across the side edges to comprise the target face. The covering layer help retain the target elements in the stacked configuration and provides a surface for applying target indicia.

Abstract: A backstop for decelerating and trapping projectiles generally includes a support structure having an inclined surface and a projectile trapping medium disposed on the inclined surface. The projectile trapping medium may be either a resilient granular ballistic medium or a combination of a ballistic medium with a hydrated super absorbent polymer (SAP) gel. Preferably, the support structure is made of a shock absorbing, foamed, fiber-reinforced concrete, such as SACON®. In embodiments, the support structure also includes an enclosure. Additives may also be mixed into the projectile trapping medium to control alkalinity and prevent leaching of heavy metals.

Abstract: A foldable backboard for protecting an area surrounding a dartboard is provided. The backboard includes a pair of generally identically shaped base pieces. Each base piece has a front face, a rear face, is formed of a generally rigid, lightweight material. The base pieces are positioned adjacent to each other. At least one outer layer of flexible material covers the front faces of both of the base pieces and joins the base pieces together along a fold line of the flexible material.

Abstract: A bullet trap with a passageway defined between flat upper and lower boundary walls extending convergingly, at opposite angles of inclination of between 0.degree. and about 15.degree. to the horizontal, from an entrance opening to an exit opening or throat, and a deceleration chamber having a generally spirally curved circumferential boundary wall and provided in its upper region with an inlet opening and in its lower region with a discharge opening leading to a collecting vessel. The circumferential boundary wall of the chamber is constituted by two oppositely concave channel-shaped members the respective upper end regions of which are spaced from each other to define the inlet opening, and the respective lower end regions of which are spaced from each other to define the discharge opening. The chamber communicates at its upper region with the passageway substantially tangentially of the chamber via the directly adjacent inlet opening and throat, and a liquid lubricating fluid can be directed into the chamber from the collecting vessel either in a forced flow mode (pump-activated) through the inlet opening or in a passive mode (bullet-activated) through the discharge opening. For the special purpose of enabling a previously fired firearm to be checked for whether a bullet remains in the firing chamber of the firearm, the trap may have the same basic construction but without the liquid lubricating fluid feature.

Abstract: There is a disclosed method and apparatus for trapping bullets in an indoor range having a first end and a second end by use of a bullet trap. The bullet trap is formed from an upper plate and a lower plate and a liquid-filled trough. The bullet trap is positioned near the second end of the indoor range. The upper plate and said lower plate converge together toward the second end of the indoor range to form a horizontally positioned slot between an upper end of the lower plate and a portion of the upper plate. The upper plate preferably curves downwardly between the slot and the second end of the range and ends in a generally vertically downward orientation pointed toward the liquid filled trough. Bullets fired into the bullet trap from the first end of the range pass through the slot and are trapped in the liquid filled trough. The method keeps airborne lead concentrations at low levels.

Abstract: A bullet stop and containment chamber for stopping the forward momentum of projectiles traveling in a generally horizontal zone of projectile travel. The bullet enters the wide end of a channel having plates which guide the bullet into a narrow opening which leads into a containment chamber. The containment chamber has a series of plates arranged with increasing angles of incidence such that the sequential impacts are increasingly direct. There are also side plates on the chamber which combine with the other structure to confine bullets, fragments and particulate matter to the chamber until inertial momentum is arrested and the bullet drops out of an egress.
