Patent Application
20230384054
The present invention relates to a blaster that shoots projectiles, and more particularly to a blaster that includes a variable velocity barrel assembly.
Blasters that shoot projectiles, such as gel based balls, paint balls and the like can be utilized by people of all ages. However, the projectiles can hurt or cause pain when they strike a person. For example, younger children may not want to be hit by a gel based ball that causes pain. Accordingly, a way to slow or vary the velocity of the projectiles is needed.
The background description disclosed anywhere in this patent application includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
In accordance with a first aspect of the present invention, there is provided a blaster for shooting projectiles that includes a housing that defines a housing interior, and a variable velocity barrel assembly positioned in the housing interior. The variable velocity barrel assembly includes a barrel that defines a barrel axis and a barrel interior. The barrel includes an exit opening at a distal end thereof. At least a first opening communicates the barrel interior with an exterior of the barrel. The first opening is defined through a side wall of the barrel. A slider member that includes a cylindrical portion that surrounds the barrel is movable axially along the barrel between a maximum velocity position where the cylindrical portion covers the first opening and a minimum velocity position where the slider member does not cover the first opening.
The present invention includes a pneumatic mechanical subassembly that is configured to be used with a blaster that fires spherical or other projectiles, (exemplary blasters include the Surge 1.5 and GB2011 1.0, which fire gel based balls referred to commercially as Gellets and are sold by GEL BLASTER®) and may be referred to herein as a variable velocity barrel assembly. The variable velocity barrel assembly allows a user to select their desired projectile velocity by manually manipulating or moving a slider member forwards and backwards to increase or decrease velocity. The system or assembly works by exposing or covering side vents or openings in the barrel, thereby proportionally decreasing or maintaining venting blast pressure behind each projectile as it exits the chamber, to affect vacuum-formed drag behind each projectile.
For example, as a result of the movement of the slider member, the variable velocity barrel assembly or vented release system can provide a velocity of the fired projectile in a range between 85 ft/sec (where a user will barely feel the projectile) and 250 ft/sec (where the projectile may cause some slight pain). Between <90 ft/sec and 175 ft/sec is another possible range provided by the various openings. Any velocity or speed within these ranges is within the scope of the present invention. In a preferred embodiment, the barrel includes openings on both sides thereof and includes between one and four sets or pairs of openings (between one and up to twenty pairs of openings is within the scope of the present invention). Openings on only one side (or the top or bottom) of the barrel is also within the scope of the invention.
The invention, together with additional features and advantages thereof, may be best understood by reference to the following description.
The invention may be more readily understood by referring to the accompanying drawings in which:

The terms used in this specification generally have their ordinary meanings in the art, within the context of the disclosure, and in the specific context where each term is used. Certain terms that are used to describe the disclosure are discussed below, or elsewhere in the specification, to provide additional guidance to the practitioner regarding the description of the disclosure. For convenience, certain terms may be highlighted, for example using italics and/or quotation marks: The use of highlighting has no influence on the scope and meaning of a term; the scope and meaning of a term is the same, in the same context, whether or not it is highlighted.
It will be appreciated that the same thing can be said in more than one way. Consequently, alternative language and synonyms may be used for any one or more of the terms discussed herein. No special significance is to be placed upon whether or not a term is elaborated or discussed herein. Synonyms for certain terms are provided. A recital of one or more synonyms does not exclude the use of other synonyms. The use of examples anywhere in this specification including examples of any terms discussed herein is illustrative only, and is not intended to further limit the scope and meaning of the disclosure or of any exemplified term. Likewise, the disclosure is not limited to various embodiments given in this specification.
Without intent to further limit the scope of the disclosure, examples of instruments, apparatus, methods and their related results according to the embodiments of the present disclosure are given below. Note that titles or subtitles may be used in the examples for convenience of a reader, which in no way should limit the scope of the disclosure. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. In the case of conflict, the present document, including definitions, will control.
It will be appreciated that terms such as “front,” “back,” “top,” “bottom,” “side,” “short,” “long,” “up,” “down,” “aft,” “forward,” “inboard,” “outboard” and “below” used herein are merely for ease of description and refer to the orientation of the components as shown in the figures. It should be understood that any orientation of the components described herein is within the scope of the present invention.
The present invention is a variable velocity barrel assembly that is configured to be used with a blaster that fires spherical or other projectiles. In a preferred embodiment, as shown in
It will be appreciated that, in use, as the projectile is fired through and travels down the barrel 24, there is a point or section within the barrel 24 where the projectile reaches its maximum velocity. The barrel 24 and barrel interior includes a velocity portion 23, section or distance along the barrel through which the projectile reaches this maximum velocity. The velocity portion 23 is part of the variable velocity barrel assembly 14. The velocity portion 23 includes the openings 18 that are defined through the barrel (communicating the barrel interior with the barrel exterior). The opening 18 can be any shape.
It will be appreciated that the more openings 18 that are exposed, the more pressure that is released, thus slowing the velocity or speed of the fired projectile. During use or firing of a projectile, pressurized gas that is pushing the projectile through the barrel is released or vented through the openings 18 (creating a muzzle break), thereby releasing pressure and limiting the velocity of the fired projectile as it exits the barrel 24. The slider member 16 is slideable between a maximum velocity position (where all openings 18 are covered) and a minimum velocity position (where all openings 18 are exposed) and one or more intermediate velocity positions, where the velocity increases as more openings 18 are covered by the cylindrical portion. The positions are each user selectable. The seal members 20 create a seal with the inner surface of the cylindrical portion 22 to prevent gas from escaping through the covered openings 18 (openings or sets of openings that are positioned between seal members).

In another embodiment, the slider member can include a lever for moving the slider member axially. In another embodiment, the slider member can include an arm extending therefrom that can be movable into vertically oriented slots or detents to keep the slider member in the proper position. The extension members can also extend sideways or sidewardly to provide access to the handle portion on a side of the barrel portion of the housing.
The present invention also includes the method of varying the velocity by moving the slider member 16 axially along the barrel to cover or uncover or expose or seal off one or more openings or sets of openings. This is done by creating a seal with one of the seal members and the inner surface of the cylindrical portion so that air is expelled through the openings that provide fluid communication between the barrel interior and the barrel exterior, if any. The method may also include removing the removable member to access the handle portion and then placing the removable member back into position.
