摘要:
A combined blow gun and projectile wherein the blowgun includes an elongated tubular component, a mouth piece, at least one sensor, and a visual indicator for projectile speed. The kit is simple and provides a method of qualitatively evaluating breath force whether for sport or for medical purposes.
摘要:
An elastomeric blow pipe dart (10) including: a generally circular body portion (12); a tapered portion (16) extending from the generally circular body portion (12); and a nose (18) having a smaller diameter than the tapered portion (16) and extending from the tapered portion (16) to a tip (20). The blow pipe dart (10) may comprise a soft rubber, and the nose (18) may define an end bore (26) so that air passes through the nose (18) when the dart (10) is launched.

摘要:
A combustion device has a controllable venting mechanism, within a piston/plunger or a chamber/housing, to allow the flow of air out of the chamber to enable the piston/plunger to be freely inserted for the purpose of storage or to maintain the air within the chamber to enable the piston/plunger to create a pressure necessary for combustion.

An apparatus for efficiently and accurately launching subcaliber projectiles comprises: an elongate barrel; a magnetic detent; an associated discarding sabot; and an associated subcaliber projectile. In one embodiment, the subcaliber projectile includes a steel shot which may be held in place by the magnetic detent against the inner surface of the barrel bore in readiness for launching, and the sabot includes two identical faces, one face serving as a thrust-transmitting face that engages the projectile and the other face serving as a thrust-pressurization face that receives thrust pressure provided by the user's breath. In an alternative embodiment, the sabot fits sufficiently loosely within the barrel bore to permit the sabot to slide through the bore under gravitational urging. Another alternative embodiment includes a crossbar detent to stop the sabot from exiting the bore through the breech opening. Other alternative embodiments are disclosed.

A sport blow gun is a blow gun which is a tube with a bore, a loading end and a muzzle end. A projectile is inserted into the loading end and blown out the muzzle end by the user's breath. The main tube features a safety device which prevents a projectile from falling out of the tube or being inhaled. One type of projectile fired from the blow gun is a dart which is usually comprised of foam or soft material, and may also be made out of a material which causes relatively little resistance as it passes through the bore, yielding higher velocity. The projectile may also be coated with a coating which reduces resistance with the bore. Projectiles may also be modified in form for aerodynamic efficiency.

A blow gun includes an ammunition chamber having an internal volume that is large enough to hold at least 30 spherical projectiles, for example plastic BBs. The ammunition chamber has a breath receiving orifice for receiving exhaled breath into the ammunition chamber. A barrel obtrudes from the ammunition chamber. The barrel has a cylindrical bore therethrough, that defines an internal diameter that is greater than the spherical projectile diameter but no greater than 1.7 times the spherical projectile diameter. The ammunition chamber includes a resilient handle portion that is squeezable to displace spherical projectiles within the ammunition chamber.
摘要:
A blow gun includes a hollow ammunition chamber having an internal volume that is large enough to hold at least 30 spherical projectiles, for example plastic BBs. The ammunition chamber has a breath receiving orifice, and a firing port. A barrel obtrudes from the hollow ammunition chamber through the firing port. The barrel has a cylindrical bore therethrough, that defines an internal diameter that is greater than the spherical projectile diameter but no greater than 1.7 times the spherical projectile diameter. The barrel has an outer surface that is in sliding contact with the firing port. The barrel may have a storage position in which most of the barrel is disposed within the internal volume of the hollow ammunition chamber, and a firing position in which most of the barrel is disposed outside of the hollow ammunition chamber.
