The size of the handle makes it impossible for children to operate. The trigger cannot be moved to its firing position unless the gun is cocked, the gun housing is closed, and a manual safety button is actuated during firing. To prevent unintended projectiles from being inserted into the barrel, the front of the barrel is blocked except during firing and the rear of the barrel is blocked at all times by either the projectile-carrying magazine or a barrel block.Type: GrantFiled: March 16, 1988Date of Patent: May 30, 1989Assignee: LJN Toys, Ltd.Inventors: Harry R. Moorhouse, Robert M. Jensen, Tat K. Chung

Patent number: 4759336Abstract: An underwater speargun consisting of two spears that are independent of each other. This underwater speargun is capable of 2 rapid discharges of spears or 2 simultaneous discharges of spears. Accidental firing is prevented due to the safety blocking the trigger until the trigger and the safety trigger are squeezed rearward at the same time. Grooved tracks and front spear guides help insure the spear propels out of the gun in a straight path.Type: GrantFiled: September 26, 1986Date of Patent: July 26, 1988Inventor: Patrick F. Frain

Patent number: 4602608Abstract: A supply mechanism for gas projectile firing devices includes: a magazine having a storage column for projectiles and a transfer slide for moving projectiles from a column to a position in line with the firing chamber; a mobile element having a transfer bar for moving the transfer slide from the column to its position next to the firing chamber, an insertion piston for moving projectiles from the transfer slide into the firing chamber and a firing pin for opening the valve connecting the compressed gas reservoir to the firing chamber; a trigger which activates the firing and prevents double insertion of a projectile, and a cocking rod which controls the mobile element and the trigger. The mechanism is applicable to training and sports weapons, and to nail and staple guns.Type: GrantFiled: May 29, 1984Date of Patent: July 29, 1986Assignee: Etat Francais represente par le Delegue General pour l'armementInventors: Jean S.

Patent number: 4513527Abstract: An animal trap and ball detent trigger means therefor is disclosed. The trap is of shaft and block construction with the cable carrying block spring biased toward one end of the shaft. The shaft is longitudinally bored at one end thereof with a transverse bore intersecting the longitudinal bore for receiving ball bearings to be used for detaining the cable carrying block in a set position against a spring bias. A plunger extends into the longitudinal bore for reciprocating between a position holding the ball bearings in a block detaining position and a position in which the ball bearings may be forced inwardly into the shaft to release the block. The plunger and a trigger member are spring biased in a home set position. The trigger member has a conically shaped end which rests in a correspondingly conically shaped trigger block with one end of the plunger in spring bias contact therewith.Type: GrantFiled: October 22, 1982Date of Patent: April 30, 1985Inventor: Dale L. Wicklund

Patent number: 4345402Abstract: A toy vehicle and a launcher includes an integral latch mechanism for holding the vehicle in a biased position and an actuating member for selectively releasing the latch. The vehicle includes an elongated tube of substantially dense, rigid material defining a frame to which wheels may be secured. The tube is encased within a soft, resilient, open cell foam material such as polyurethane foam which has been molded in the form of a vehicle body. A resilient, biasing member is mounted within the tube and is held in a compressed state by the latch. The launching member includes connection means to permit the connection of a series of launching members.Type: GrantFiled: December 4, 1980Date of Patent: August 24, 1982Assignee: Marvin Glass & AssociatesInventors: Steven P. Hanson, Robert E. Smathers, Howard J. Morrison

Patent number: 4318389Abstract: A spear gun is collapsible to approximately one-half of the full length of a conventional spear gun by the use of both (1) a spear made of two parts and (2) by the use of a hollow shortened spear gun housing from which an extension for holding the slings or elastics for propelling the spear may protrude. The extension is slidably mounted within the hollow spear gun housing and has at its outer end a sling holder, or arrangements for holding the slings or elastics. The spear has a threaded coupling halfway along its length so that the spear may be unthreaded and the two parts thereof both secured along the length of the housing. One of the parts may be stored on the gun when the gun is not in use. A special compact trigger mechanism may include a release shaft in the hand grip of the spear gun which interfits with a recess in the spear, and is provided with a thumb actuated release. Concurrently with releasing the spear, the other end of the shaft includes a mechanism which releases the spear retaining line.Type: GrantFiled: September 22, 1980Date of Patent: March 9, 1982Inventor: Zoltan C. Kiss, Jr.

Patent number: 4291809Abstract: A pencil holder includes a body having a socket, the body including a substantially horizontal base portion. A pencil is selectively received in the body socket and engages a compression spring located longitudinally within the body socket. A hook having a hooked end portion within the base portion and a longitudinal portion extending the length of the spring within the body socket and engaging the spring to retain the spring compressed upon insertion of the pencil in the body socket. A catch block within the base portion selectively engages the hooked end portion of the hook when the spring is in a compressed state. A guide vane is located adjacent to the catch block. The guide vane has a curved end underlying the catch block. The guide vane engages the hooked end portion, and the curved end aligns the hooked end portion with the catch block when the spring is being compressed.Type: GrantFiled: January 11, 1980Date of Patent: September 29, 1981Inventor: Edwin J. Lyon

Patent number: 4214674Abstract: A toy water gun assembly capable of ejecting water in bursts or in a continuous manner, is disclosed. A separate, pressurizable water container is connected by a flexible hose, to a pistal shaped member. A section of the flexible hose, mounted in the pistol shaped member, is continuously clamped by a lever. A spring biases the lever to prevent the release of a water stream through a nozzle which is mounted on the front of the pistol shaped member. A trigger member having a pointed pawl pivotably mounted thereto, is operatively connected to the lever. An initial movement of the pawl member caused by a quick pull on the trigger member momentarily removes the lever from its position clamping the hose. Additional movement of the pawl causes it to slide off the lever, thereby allowing the lever to return to its regular position wherein the hose is clamped.Type: GrantFiled: May 30, 1978Date of Patent: July 29, 1980Assignee: California R & D CenterInventors: Lawrence T. Jones, Anson Sims, Ashley G. Howden

Patent number: 4170215Abstract: An inexpensive mechanical launcher for launching certain toy disks consists of two predominantly planar pieces of pre-formed plastic material joined together forming a slotted receptor and a handle portion. A toy disk is inserted in the slotted receptor and engages a catch with its outside rim. A spring for biasing the disk against the catch is preloaded during insertion and is engaged with a notch on the disk rim. A plunger having a manually engageable trigger retracts the catch and allows the spring to return to its released position, thus flinging the disk in an outwardly spinning trajectory which can be influenced and altered by varying the axial position of the launcher before release.Type: GrantFiled: January 6, 1978Date of Patent: October 9, 1979Inventor: John S. Kettlestrings
