The disclosure relates to the field construction and modification of firearms.
A bolt-action firearm may be operated by manually moving a slide (also referred to as a bolt) of a firearm to expose a chamber of the firearm. When the chamber is exposed, a spent cartridge may be ejected and a new cartridge may be inserted. Then the slide may be returned to an original position to close the chamber of the firearm which is then loaded.
Various implementations of the present disclosure will be understood more fully from the detailed description given below and from the accompanying drawings of various implementations of the invention.
Various jurisdictions regulate the possession of firearms. Such restrictions may be based on a type of firearm, technical specifications of firearms, manufacturer, or other characteristics. Additionally, some individuals may prefer firearms that have specific characteristics. For example, an individual may prefer to own and use pistols, rifles, shotguns, or other types of firearms. In addition, an individual may prefer some manufacturers to others. In some situations, an individual may prefer to own or manufacture a firearm that operates with a bolt-action slide. This may be to suit an individual preference of a gun owner or may be to satisfy one or more regulations in a particular jurisdiction.
A bolt-action slide on a firearm may be used to chamber a bullet by pulling a charging handle to pull back the slide and expose an open chamber. The chamber may then receive a bullet placed into the chamber or from a magazine or other bullet source. Repositioning the charging handle to the original position chambers the bullet in the position with the barrel of the firearm.
A bolt-action slide conversation device as described herein may convert a slide of a firearm to operate as a bolt-action slide. Thus, a slide that would not function as a bolt action slide may function as a bolt action slide after the bolt-action slide conversation device is coupled to the slide. In an example, the bolt-action conversion device may prevent a firearm slide from opening the chamber of a firearm in response to a shot being fired. For instance, in a pistol, a typical slide may slide back to open the chamber of the pistol in response to firing a shot. However, when the firearm slide is coupled to the bolt-action slide conversion device, the firearm slide does not automatically open a chamber in response to firing a bullet. Instead, the chamber remains sealed. This may improve the accuracy or speed of the bullet that is fired. After the bullet is fired, a new cartridge may be loaded by pulling a charging handle to move the slide to expose the chamber.
In order to convert a slide to be a bolt-action slide, the bolt-action conversion device may use a locking plate to prevent the slide from automatically exposing the chamber when a shot is fired. The locking plate may be operatively coupled to a clamp assembly. The clamp assembly may be attached to a slide. Thus, the clamp assembly may have one or more retainers to position the locking plate at the front of a barrel of a firearm without obstructing the firing of a bullet from the muzzle of a gun. When a bullet is fired, the locking plate is in contact with the front of the firearm to stop the backward force exerted by the bullet on the slide from moving the slide.
The figures and associated description are generally described herein with reference to pistols. However, the bolt-action conversion device may also be used for rifles, shotguns, or other firearm configurations. Furthermore, the bolt-action conversion device may be used on a slide of a firearm with an attached magazine that automatically loads a cartridge when the charging handle is pulled back to expose the chamber, or may be used on a slide of a single shot firearm that may load cartridges one at a time from a source other than an attached magazine.
The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of the claimed disclosure. However, various aspects of the disclosed implementations may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.
In the configuration shown in
When the locking plate 150 is inserted into the receiving slots 115 as shown in
As shown in
The locking plate 110 may have a charging handle 162 that enables bolt-action operation of the firearm. The charging handle 162 may be used to rotate the locking plate 110 about an axis defined by the pivot pin 154. When a force is applied to the charging handle 162 that exceeds a force applied by the torsion spring 152, the locking plate 150 may rotate to expose the front of the frame 20 of the firearm.
As shown in
After the chamber 17 is exposed, a casing may be removed or a new bullet may be loaded. The bolt-action conversion device 100 may then be moved back to the front of the firearm and the locking plate 150 may be rotated into the receiving slots 115 to chamber the bullet and prepare the firearm for firing. For example, the bolt-action conversion device 100 may be moved from the configuration shown in
The locking plate 150 may have a pivot pin hole 155 that is aligned with a pivot pin hole (not shown) of the slide clamp 110. When a pivot pin is placed into the pivot pin hole 15 while aligned with the pivot pin hole of the slide clamp 110, the pivot pin may enable the locking plate 110 to rotate with respect to the slide clamp 110 around an axis defined by the pivot pin. The locking plate 150 may have a first torsion spring retainer 156 that is part of the locking plate 150 and the slide clamp 110 may have a second torsion spring retainer 158. The torsion spring retainers may receive a torsion spring to apply a force that positions the locking plate 150 into receiving slots 115 of the slide clamp 110.
The receiving slots 115 may be rectangular slots that receive a rectangular locking plate 150 as shown in
When the locking plate 150 is inserted into the receiving slots 115 as shown in
In some embodiments, the upper surface 160 of the locking plate 150 may be curved as shown in
The slide clamp 110 may have one or more screw holes 122 that are configured to receive one or more securing screws (not shown) that couple the slide clamp 110 to a firearm slide. In some embodiments, the slide clamp 110 may include one or more retaining plates on the inside surface of the slide clamp that distributes the force of the screws to couple the slide clamp 110 to a slide. In some embodiment, the retaining plates may be rubber, plastic, or another suitable material that will not damage a slide while providing a secure coupling of the slide clamp 110 to a slide.
The locking plate 150 in
The locking plate 150 may be made of steel, aluminum, a plastic or ceramic composite material, or any other suitable material. In addition to the structure shown, in some embodiments, the locking plate 150 may further include one or more rubber or plastic layers. For example, a surface of the locking plate 150 that contacts the frame of the firearm may be lined completely or partially by a layer of rubber to protect the surface of the frame.
The slide clamp 110 comprises a number of screw holes 122 to receive securing screws to couple the slide clamp 110 to a slide of a firearm. The slide clamp 110 also includes a pivot pin hole 155 to receive a pivot pin that couples a locking plate to a slide clamp 110. Receiving slots 115 a shaped to receive a locking plate as discussed with reference to
The perspective of
In some embodiments, the slide clamp 110 may include a channel along the interior surface of the clamp that may be positioned to provide an unobstructed view of a firearm's sights. For example, the channel may provide a view of the front and rear sights of a firearm. In some embodiments, a channel may instead be positioned on the exterior surface of a slide clamp 110 to enable viewing of the firearm sights above the slide clamp 110. In some embodiments, the slide clamp 110 may include sights on the front or rear that can be used for targeting the firearm. The slide clamp 110 may be made of steel, aluminum, a plastic or ceramic composite material, or any other suitable material. In addition to the structure shown, in some embodiments, the slide clamp 110 may further include one or more rubber or plastic layers. For example, the interior surface 120 may be lined completely or in part by a layer to protect the surface of the firearm slide.
The locking plate retainer 210 may include a torsion spring retainer 258, receiving slots 215, a pivot pin hole (not shown) and other features analogous to those described with reference to the slide clamp 110 above. The receiving slots 115 of the locking plate retainer 210 may position the locking plate 150 in front of a frame of a firearm without obstructing the barrel 25 of the firearm. Accordingly, the locking plate 150 may stop the slide 15 of the firearm from sliding in response to the firing of a bullet from the firearm. The slide 15 of the firearm may be operated in the same manner as the locking plate 150 described above with reference to
In the description herein, numerous specific details are set forth, such as examples of specific types of processors and system configurations, specific hardware structures, specific architectural and micro architectural details, specific register configurations, specific instruction types, specific system components, specific measurements/heights, specific processor pipeline stages and operation etc. in order to provide a thorough understanding of the present disclosure. It will be apparent, however, that these specific details need not be employed to practice the present disclosure. In other instances, well known components or methods, such as specific and alternative processor architectures, specific logic circuits/code for described algorithms, specific firmware code, specific interconnect operation, specific logic configurations, specific manufacturing techniques and materials, specific compiler implementations, specific expression of algorithms in code, specific power down and gating techniques/logic and other specific operational details of computer system have not been described in detail in order to avoid unnecessarily obscuring the present disclosure.
Use of the phrase ‘configured to,’ in one implementation, refers to arranging, putting together, manufacturing, offering to sell, importing and/or designing an apparatus, hardware, logic, or element to perform a designated or determined task. In this example, an apparatus or element thereof that is not operating is still ‘configured to’ perform a designated task if it is designed, coupled, and/or interconnected to perform said designated task. Note once again that use of the term ‘configured to’ does not require operation, but instead focuses on the latent state of an apparatus, system, and/or element, where in the latent state the apparatus, system, and/or element is designed to perform a particular task when the apparatus, system, and/or element is operating.
Furthermore, use of the phrases ‘to,’ ‘capable of/to,’ and or ‘operable to,’ in one implementation, refers to some apparatus, system, and/or element designed in such a way to enable use of the apparatus, system, and/or element in a specified manner. Note as above that use of to, capable to, or operable to, in one implementation, refers to the latent state of an apparatus, logic, hardware, and/or element, where the apparatus, logic, hardware, and/or element is not operating but is designed in such a manner to enable use of an apparatus in a specified manner.
Reference throughout this specification to “one implementation” or “an implementation” means that a particular feature, structure, or characteristic described in connection with the implementation is included in at least one implementation of the present disclosure. Thus, the appearances of the phrases “in one implementation” or “in an implementation” on “in some implementations” in various places throughout this specification are not necessarily all referring to the same implementation. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more implementations.
In the foregoing specification, a detailed description has been given with reference to specific exemplary implementations. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the disclosure as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense. Furthermore, the foregoing use of implementation and other exemplarily language does not necessarily refer to the same implementation or the same example, but may refer to different and distinct implementations, as well as potentially the same implementation.
The words “example” or “exemplary” are used herein to mean serving as an example, instance or illustration. Any aspect or design described herein as “example’ or “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the words “example” or “exemplary” is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X includes A or B” is intended to mean any of the natural inclusive permutations. That is, if X includes A; X includes B; or X includes both A and B, then “X includes A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. Moreover, use of the term “an implementation” or “one implementation” or “an implementation” or “one implementation” throughout is not intended to mean the same implementation or implementation unless described as such. Also, the terms “first,” “second,” “third,” “fourth,” etc. as used herein are meant as labels to distinguish among different elements and may not necessarily have an ordinal meaning according to their numerical designation.
