Firearms recoil spring insert and recoil spring insert assembly

Abstract

A recoil spring assembly for a firearm provides a spring insert with an end piece. The end piece interacts with other components of the firearm to selectively secure the recoil spring in position. This allows the recoil spring to be selectively retained in the firearm when disassembling and reassembling the firearm.

Claims

1. A firearm comprising: a recoil spring comprising coils forming a tunnel; a recoil spring insert disposed in the tunnel, the recoil spring insert comprising: a main body that fits inside the tunnel, the main body having a proximate end, wherein the main body defines a horizontal axis; and an end piece on the proximate end of the main body, the end piece comprising an extended portion connected to and extending above the end such that the extended portion extends perpendicular to and above the horizontal axis; and a grip insert comprising a surface shaped to form a slot extending perpendicular to and above the horizontal axis, wherein the slot is configured to receive and secure the extended portion of the end piece of the recoil spring insert.

2. The firearm of claim 1, further comprising a grip comprising a bore.

3. The firearm of claim 2, wherein the grip insert comprises a bore.

4. The firearm of claim 3, further comprising a pin configured to extend through the bore of the grip and the bore of the grip insert.

5. The firearm of claim 4, wherein the extended portion is configured to disengage with the slot when (i) the pin is removed from the bore of the grip and the bore of the grip insert and (ii) the grip insert is rotated to release the extended portion from the slot.

DETAILED DESCRIPTION

(9) The following discussion is directed to various embodiments of the invention. The term “invention” is not intended to refer to any particular embodiment or otherwise limit the scope of the disclosure. Although one or more of these embodiments may be preferred, the embodiments disclosed should not be interpreted, or otherwise used, as limiting the scope of the disclosure, including the claims. In addition, one skilled in the art will understand that the following description has broad application, and the discussion of any embodiment is meant only to be exemplary of that embodiment, and not intended to intimate that the scope of the disclosure, including the claims, is limited to that embodiment.

(10) In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . .” Also, the term “connect” or “connected” where used if at all is intended to mean either an indirect or direct connection. Thus, if a first component connects to a second component, that connection may be through a direct connection or through an indirect connection via other components and connections.

(11) Certain terms are used throughout the following description and claims to refer to particular system components and method steps. As one skilled in the art will appreciate, different companies may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not function.

(12) FIG. 1 is a perspective exploded side view of a recoil spring assembly of the present invention. Grip 110 houses grip insert 130, which provides bores 132/134 to receive pin 140. Grip insert 130 provides surface 136 which has a curved portion that defines an upper horizontal portion and a lower vertical portion. Recoil spring 120 is housed in grip 110 beneath pin 140 receiving bores 112/114. Recoil spring 120 houses spring insert 122, which provides end piece 125, to form a recoil spring assembly 128 comprising spring insert 122 having end piece 125 housed in spring 120.

(13) FIG. 2 is a perspective side view of an assembled recoil spring assembly of FIG. 1. Assembly 210 comprises grip 110 which houses recoil spring 120 and grip insert 130. Pin 140 is inserted through grip bores 112/114 and grip insert bores 132/134 (see FIG. 1) to retain recoil spring assembly 128.

(14) FIG. 3 is a perspective right-side cross-section view of a recoil spring assembly of the present invention. Recoil spring assembly 128 is disposed in grip 110 beneath pin 140. End piece 125 is oriented to be captured by grip insert 130 along the vertical portion of surface 136 so as to retain spring 120 in grip 110 even if pin 130 were to be removed.

(15) FIG. 4 is a perspective left-side cross-section view of a recoil spring assembly of FIG. 3. Recoil spring 120 is disposed in grip 110 beneath pin 140. End piece 125 of spring insert 122 secures spring 120 in position.

(16) FIG. 5 is a left-side cross-section view of a recoil spring assembly of FIG. 4. End piece 125 is captured in space or slot 510 formed by surface 136 of grip insert 130.

(17) FIG. 6 is a left-side cross-section alternative view of a recoil spring assembly of FIG. 4. End piece 125 is oriented to fit into space or slot 510 to retain spring 120 in position.

(18) FIG. 7 is a right-side cross-section alternative view of a recoil spring assembly of FIG. 3. End piece 125 of spring insert 122 retains spring 120 in position.

(19) Spring insert 122 is selectively disengaged from slot 510 by removing pin 140. With pin 140 removed, grip insert 130 can be rotated to release spring insert 122 from slot 510 of grip insert 130. To selectively engage spring insert 122 with slot 510, restore spring insert 122 to its position in grip 110 and rotate grip insert 130 to engage end piece 125 in slot 510. When end piece 125 is engaged with slot 510, spring 120 is secured in the firearm. When end piece 125 is not engaged with slot 510, spring 120 is not secured to the firearm and maybe be removed from the firearm by the user if so desired.

(20) Many modifications and other embodiments of the recoil spring insert described herein will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosure is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
