BACKGROUND1. Field of the Invention
The present invention relates generally to magazine loaders and, more particularly, to a rapid magazine loader device.
2. Introduction
Ammunition is fed into a firing chamber via a removable magazine holding multiple rounds of ammunition. Ammunition is typically loaded into the magazine manually by hand. This entirely manual loading process can be a tedious operation. In one example, a tool can be used in combination with a hard surface to push an existing cartridge down into the magazine. The user would then manually insert a cartridge into the top of the magazine. In another example, manufacturers have designed tools that load a magazine by pushing ammunition cartridges into the magazine via a downward-loading motion. What is needed is an efficient magazine loading mechanism.
In order to describe the manner in which the above-recited and other advantages and features of the invention can be obtained, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Various embodiments of the invention are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the invention.
As noted, manual insertion of cartridges into a magazine is tedious and time consuming. In accordance with the present invention, a rapid magazine loader device is provided that obviates the need for manual insertion of cartridges in the magazine.
In one embodiment, the first and second sides of the pistol magazine loader device 100 differ slightly. The first side of the pistol magazine loader device 100 (

The loading of cartridges into the magazine 800 is facilitated by the control element 400 (see
As illustrated, the control element 400 includes a hole 410 formed in a front end of the control element 400. The hole 410 is designed to receive the coupling portion 620 of the handle 600. In one embodiment, the coupling portion 620 includes a threaded portion that screws into the corresponding threads formed in the wall of hole 410. As would be appreciated, various methods by which handle 600 can be permanently or removably coupled to the control element 400 can be used. In one embodiment, a portion of the coupling portion 620 that extends from the hole 410 is designed for slidable engagement with the slot 150 formed in the second side of the pistol magazine loader device 100 (see
The slidable engagement of the coupling portion 620 with the slot 150 produces horizontal and/or vertical movement of the control element 400 as the user directs the handle 600 along a path guided by the slot 150. As noted above, the vertical movement of the rear portion of the control element 400 is constrained by the pin 140 and the magazine well guide 142.
As
In one embodiment, the movement of the handle 600 forward would cause the rod portion 230 of the plunger 200 to move from a first end 421 of the slot 420 along the slot segment 422. This movement of the rod portion 230 along the slot segment 422 can be designed to retain the plunger 200 in a relatively fixed position above the magazine follower or cartridge in the top-most position of the magazine. The transition of the rod portion 230 from slot segment 422 to slot segment 424 can be designed to initiate the downward motion of the plunger 200. More specifically, the movement of the rod portion 230 along the slot segment 424 would cause the tabs 222, 224 to slide down the slots 132, 134, thereby lowering the plunger portion 210 to engage the magazine follower or the top-most cartridge in the magazine 800. The transition of the rod portion 230 from slot segment 424 to slot segment 426 can be designed to retain the plunger portion 210 at a depressed position in the magazine 800 until the rod portion 230 reaches a second end 429 of the slot 420. As will be described in greater detail below, the timing of the movement of the rod portion 230 forward and back through the slot segment 424 is designed to coincide with the simultaneous control of the cartridge pusher 300 by the control element 400.
The cartridge pusher 300 is coupled to the control element 400 through the slidable engagement of the tab 320 of the cartridge pusher 300 along the slot 430 formed in the control element 400. As illustrated, a notch 432 is further formed on one end of the slot 430. As will be described in greater detail below, the notch 432/slot 430 combination acts as a delay circuit for the cartridge pusher 300 in synchronizing the movement of the cartridge pusher 300 relative to the movement of the plunger 200.
The cartridge pusher 300 is designed to fit into a channel 510 formed in the cartridge tray 500 (see
Cartridges are loaded into the channel 510 in the cartridge tray 500 via a well 170 formed in the top of the pistol magazine loader device 100. Multiple cartridges can be loaded into the well 170 for individual feeding of cartridges into the magazine 800. The well 170 which is formed using the first and second sides of the pistol magazine loader device 100 and the well wall sides 180 and 190. The well wall sides 180 and 190 have notches 182, 192, respectively, formed therein to provide clearance for the operation of the control element 400.
Having described an embodiment of a structure of the pistol magazine loader device 100, reference is now made to
Note that at this point, the control element 400 is in the rear-most position within the pistol magazine loader device 100. In this rear-most position, the coupling portion 620 of the handle 600 (not shown) is in the rear-most position of slot 150. Also, the rod portion 230 of the plunger 200 is engaged in substantially the end 421 of the slot 420 formed in the control element 400. In this position, the plunger 200 is in a raised position relative to the magazine 800. Additionally, the tab 320 of the cartridge pusher 300 is located at a front end 431 of the slot 430 formed in the control element 400. In this position, the cartridge pusher 300 is located above the cartridge tray 500 such that the cartridge 900 in the lowest position in the well 170 sits on the top of the cartridge pusher 300.
Referring to
At or around the time that the plunger 200 has lifted and is now clear of the incoming cartridge, the tab 320 of the cartridge pusher 300 re-engages with the end 431 of the slot 430 in the control element 430 (see

In various embodiments, the magazine is locked, clamped, or otherwise fixed inside the magazine well in the grip of the pistol magazine loader device. In one embodiment, the rapid pistol magazine loader device 1400A includes a lock 1420 that can have a ridge 1421 that engages the slot 1412 in the magazine 1410 as the lock is rotated in toward the magazine 1410. In another embodiment, the rapid pistol magazine loader device 1400B includes a clamp that would include a rotating handle 1430 with a cammed bar 1431 that would press against the magazine 1410 as the handle 1430 is rotated toward the magazine 1410.
