US12578162 - Adjusting device of toy gun
The patent describes an adjusting device for a toy gun that allows for the modification of the upward spinning force on a BB bullet by controlling the compression of a contacting element through a down-pressing controlling member. This device utilizes an adjusting screw, an adjusting wheel with guide grooves, and a positioning block to enable precise adjustments to the bullet’s trajectory.
Claim 1
1 . An adjusting device of a toy gun, the toy gun comprising a barrel portion, the adjusting device mainly comprising: a contacting element, which is attached to a side of the barrel portion to contact a BB bullet to generate an upward spinning force; a down-pressing controlling member, which is arranged on the contacting element to control a degree of contacting of the contacting element; an adjusting wheel, which is arranged on one side of the down-pressing controlling member; at least one guide groove, which is formed, in a circumferentially extending manner, on a side surface of the adjusting wheel, the guide groove being arranged to reduce a distance thereof from an axis center of the adjusting wheel in a direction of extension thereof; at least one driving portion, which is disposed on one side of the down-pressing controlling member and is arranged in the guide groove to drive the down-pressing controlling member to move; a mating portion, which is formed in a lateral edge of the adjusting wheel; an adjusting screw, which is arranged at one side of the adjusting wheel and correspondingly mates with the mating portion to drive the adjusting wheel to rotate; a positioning block, which is combined with the adjusting screw; at least three positioning facets, which are formed on a lateral of the positioning block, such that the positioning block is formed in a multiple-sided configuration; and an elastic positioning member, which is arranged at one side of the positioning block to contact at least one of the positioning facets to fix and hold the adjusting screw at a corresponding angle. a contacting element, which is attached to a side of the barrel portion to contact a BB bullet to generate an upward spinning force; a down-pressing controlling member, which is arranged on the contacting element to control a degree of contacting of the contacting element; an adjusting wheel, which is arranged on one side of the down-pressing controlling member; at least one guide groove, which is formed, in a circumferentially extending manner, on a side surface of the adjusting wheel, the guide groove being arranged to reduce a distance thereof from an axis center of the adjusting wheel in a direction of extension thereof; at least one driving portion, which is disposed on one side of the down-pressing controlling member and is arranged in the guide groove to drive the down-pressing controlling member to move; a mating portion, which is formed in a lateral edge of the adjusting wheel; an adjusting screw, which is arranged at one side of the adjusting wheel and correspondingly mates with the mating portion to drive the adjusting wheel to rotate; a positioning block, which is combined with the adjusting screw; at least three positioning facets, which are formed on a lateral of the positioning block, such that the positioning block is formed in a multiple-sided configuration; and an elastic positioning member, which is arranged at one side of the positioning block to contact at least one of the positioning facets to fix and hold the adjusting screw at a corresponding angle.
