The present invention relates generally to launcher apparatus and methods for a toy projectile blaster discharging projectiles such as foam rounds, balls, and flexible projectiles including hydrated super absorbent polymer (SAP) beads, and more particularly, for discharging plural projectile rounds in a novel fashion providing for toy blaster breechless and continuous feeding of projectiles with projectile launch alignment apparatus and methods without the use of a mechanical breech.
Toys are often designed to have play value by simulating a real object, safely and at a reasonable expense. Toy launch apparatus have been marketed as toys for decades and include such devices as water pistols, toy BB rifles, foam projectiles, balls discs, dart blasters and NERF® brand launchers that discharge a soft foam dart. Most air launchers discharging projectiles use a launch spring and a piston and cylinder arrangement to generate the energy and direct that energy to cause the projectile to discharge. The launching apparatus themselves come in various forms, including those simulating rifles, guns, machine gun, shotguns, bows, rocket launchers, grenade launchers and foam car launchers. Generally, from design and function standpoints control of the size and operation of an air chamber in the cylinder is desirable for efficiency and cost considerations.
Projectile launch mechanisms are known in the art and include mechanisms for launching toy darts, balls of various sizes, paint balls, etc. Known projectiles also include spheres of hydrated super absorbent polymer beads, such as those disclosed in U.S. Pat. Nos. 8,371,282 and 8,640,683. These patents are incorporated herein by reference. As explained in the patents, super absorbent polymer beads are able to absorb extremely large amount of liquid relative to their own mass through hydrogen bonding with water molecules. Super absorbent polymer beads are soft projectiles that can maintain their shape under modest pressure such that they can be projected with reasonable force and velocity without breaking apart. Such super absorbent polymers are often referred to as “hydrogels” or simply as “gels.” Examples of toy gel bead devices, marketed by Hasbro Inc., under the brands NERF® PRO GELFIRE™, and GEL BALL BLASTER™, stylized toy rifles that launches gel balls or ‘gelfire’ rounds. In the alternative made of NERF™ brand foam, a solid, spongy cellular material.
The inventions discussed in connection with the described embodiments address these and other deficiencies of the prior art. The features and advantages of the present inventions will be explained in or become apparent from the following summary and description of the preferred embodiments considered together with the accompanying drawings. The projectiles for such launching apparatus include soft foam darts of various designs and sizes, foam balls, also of various sizes, and other soft projectiles.
In accordance with the present invention, an advantageous method and apparatus are provided in the form of a breechless launch apparatus designed to discharge soft projectiles, with an advantageous method and system are described in the form of an improved barrel seal is aligned with a passage at the alignment module. A pre-firing area is defined inside the alignment module extending between the receptacle and the at least one barrel seal. A channel into the alignment module capable of fluid communication with the compressed air source. The pre-firing area is enabled to align at least one of the received projectiles at the at least one barrel seal by gravity.
Briefly summarized, the inventions relate to a toy launching apparatus capable of launching projectile rounds fed from a generally sealed, pressurized hopper by a combination of gravity and air flow received through a receptacle defined atop the alignment module, allowing multiple projectile rounds to be received in an eloquent configuration with continuous feeding of projectiles. The breechless projectile launcher includes the barrel seal to align received projectiles for launching through a blaster barrel with the compressed air source for causing compressed air to expel through the channel into the alignment module and outwardly launch the received projectile rounds. An actuator at the housing and linked with the compressed air source for causing compressed air to expel through the channel into the alignment module and outwardly launch the one or more received projectile rounds through the at least one barrel seal and the launching barrel.
For the purpose of facilitating an understanding of the invention, the accompanying drawings and detailed description illustrate preferred embodiments thereof, from which the invention, its structures, its construction and operation, its processes, and many related advantages may be readily understood and appreciated.
The following description is provided to enable those skilled in the art to make and use the described embodiments set forth in the best mode contemplated for carrying out the invention. Various modifications, equivalents, variations, and alternatives, however, will remain readily apparent to those skilled in the art. Any and all such modifications, variations, equivalents, and alternatives are intended to fall within the spirit and scope of the present invention.
The implementation of the generic compressed air source should not be limited to the cylinder and piston configuration in the current embodiment. Other embodiments may provide the generic compressed air source as a motorized blower or a continuous slide. The generic compressed air source may be pulsed or continuous. An actuator may be provided for the generic compressed air source. The actuator may be provided as a trigger or otherwise.
As discussed further, a barrel seal 45 is aligned with a passage 26 at the alignment module. A channel 44 into the alignment module 20 is capable of fluid communication with the compressed air source, e.g., the cylinder 16 and piston 30. Therefore, the channel 44, the passage 26, alignment module 20 and hopper may be pressurized by the generic compressed air source. In the regard, the alignment module 20 is capable of launching projectile rounds 22, A, B, C, D discussed below, received through a receptacle or hopper defined atop for allowing a plurality of the projectile rounds 22 to be received. A cover 42 to the receptacle is opened for the projectile rounds 22 to be received into a pre-firing area, which is closed for sealing the projectile rounds 22 inside the alignment module 20. The cover and the hopper with the pre-firing area are partially airtight with the cover 42 closed. The received projectiles 22 align by gravity within the pre-firing area to at the barrel seal 45. The trigger actuator linked the compressed air source causes compressed air to expel through the channel 44 into the alignment module 20 and outwardly to launch the one or more received projectile rounds 22 through the barrel seal 45 and the launching barrel 14.
With reference to
With reference to the staging of sequenced projectile rounds A, B, C, and D in
Before firing:
The round to be fired is just behind the barrel in a “pre-firing area”
The round falls into place due to gravity alone
When firing:
The air (represented by flow lines) fills the hopper but cannot escape, so it takes the path of least resistance and pushes the round out the barrel. The pressure squeezes the round slightly in the barrel. The barrel is tight enough the round would not fallout on its own.
After firing:
Gravity brings another round into the pre-firing area at the back of the barrel.
Blaster at rest, note rounds filling the bottom of the hopper because of gravity
Blaster during firing, note the rounds have been agitated by the airflow and pushed up to fill the whole hopper. This natural agitation helps prevent balls from getting stuck. It also demonstrates how the air flows through the system. Having the rounds loose in the hopper is advantageous. There may be residual air pressure within the hopper after firing, which may cause the next round to not position correctly at the barrel seal. Dampening elements may be utilized for mitigating the residual air pressure. A bleed hole 52, diaphragm 54, or dead space 56 may be provided to mitigate residual air pressure.
The present invention also discloses improved projectile alignment module methods and breechless toy blaster launch apparatus including methods of the making the toy blaster apparatus. The methods include aligning one or more projectile rounds along a passage at the alignment module including at least one barrel seal aligned with a projectile rounds launching barrel; coupling a channel capable of fluid communication with a compressed air source into the alignment module; defining a pre-firing area including a junction inside the alignment module extending between the receptacle, the channel, and the at least one barrel seal thereof, the pre-firing area enabled to align at least one of the received projectiles at the at least one barrel seal; and actuating the channel for causing the compressed air to expel through the channel into the alignment module and outwardly launch the one or more received projectile rounds through the at least one barrel seal and the launching barrel. The receiving of multiple projectile rounds through a receptacle may be further facilitated by providing the receptacle as a hopper to the alignment module with a cover being opened for the one or more projectile rounds received into the pre-firing area; and then closing the cover to the hopper for sealing the one or more projectile rounds inside the alignment module with the pre-firing area being pressurized with the cover closed allowing the compressed air to expel through the channel to the alignment module, to the hopper, and to the one or more projectile rounds for launching outwardly through the at least one barrel seal. After firing, residual air pressure may be left within the hopper which may hinder the positioning of the next projectile round. It may be desirable to reduce the residual air pressure. The dampening elements may be used to reduce residual air pressure and hence position another projectile round at the barrel seal where the projectile round may be fired in another shot.
From the foregoing, it can be seen that there has been provided features for an improved projectile alignment module and breechless toy blaster launch methods and toy air blaster apparatus with a disclosure for the method of the making the toy blaster apparatus. While particular embodiments of the improved safety valve have been shown and described in detail, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the present invention in its broader aspects. Therefore, the aim is to cover all such changes and modifications as fall within the true spirit and scope of the claimed invention. The matters set forth in the foregoing description and accompanying drawings are offered by way of illustrations only and not as limitations. The actual scope of the invention is to be defined by the subsequent claims when viewed in their proper perspective based on the prior art.
