Abstract

A magazine loader comprises a body for receiving an upper portion of the magazine and a cap slidingly engaged with the body for loading cartridges in to the magazine received by the body. The body comprises a plurality of wall portions defining a body cavity configured to receive an upper portion of a magazine. The plurality of cap wall portions may comprise a starboard cap wall portion and an opposing port cap wall portion. An upper portion of the body is slidingly received in the interior volume defined by the cap so that the body and the cap slide relative to one another along a sliding axis. The sliding axis may extend in the upward and downward directions and the cap may translate between an upper position and a lower position along the sliding axis.

First claim

What is claimed is:

1. An apparatus for loading cartridges into a magazine, comprising:
a body comprising a plurality of wall portions defining a body cavity with an opening proximate an end of the body cavity, the body cavity configured to receive a portion of the magazine, the plurality of wall portions comprising a rear body wall portion, starboard body wall portion and an opposing port body wall portion, the body further including a starboard ramp supported by the starboard wall portion and a port ramp supported by the port wall portion;
a cap comprising a plurality of cap wall portions defining an interior volume, the plurality of cap wall portions comprising a starboard cap wall portion and an opposing port cap wall portion;
a portion of the body being slidingly received in the interior volume defined by the cap wall portions so that the body and the cap slide relative to one another along a sliding axis;
the starboard cap wall portion defining a first starboard slot and a second starboard slot, the starboard cap wall including a starboard leaf spring portion disposed between the first starboard slot and the second starboard slot, the starboard leaf spring portion having a fixed end and a free end, the starboard leaf spring portion comprising a starboard ramp engaging portion proximate the free end thereof, the starboard ramp engaging portion contacting the starboard ramp;
the port cap wall portion defining a first port slot and a second port slot, the port cap wall including a port leaf spring portion disposed between the first port slot and the second port slot, the port leaf spring portion having a fixed end and a free end, the port leaf spring portion comprising a port ramp engaging portion proximate the free end thereof, the port ramp engaging portion contacting the port ramp;
the apparatus further including a latch member adapted and configured to hold the magazine in position relative to the body of the apparatus.

2. The apparatus of claim 1 wherein the body further comprises a starboard flange extending beyond the starboard body wall and a port flange extending beyond the starboard body wall; and
a throat is defined between the starboard flange and the port flange, the throat being dimensioned and configured to allow sequential passage of a plurality of individual cartridges into the body cavity.

3. The apparatus of claim 2 wherein the body further comprises a first starboard rail, the first starboard rail extending in a direction along a first starboard rail axis, the first starboard rail projecting in the starboard direction beyond a starboard facing surface of the starboard flange, the first starboard rail extending into a first starboard channel defined by the starboard cap wall.

4. The apparatus of claim 3 wherein the body further comprises a second starboard rail, the second starboard rail extending in a direction along a second starboard rail axis, the second starboard rail projecting in the starboard direction beyond a starboard facing surface of the starboard flange, the second starboard rail extending into the second starboard channel defined by the starboard cap wall.

5. The apparatus of claim 4 wherein the body further comprises a first port rail, the first port rail extending in at direction along a first port rail axis, the first port rail projecting in the port direction beyond a port facing surface of the port flange, the first port rail extending into the first port channel defined by the port cap wall.

6. The apparatus of claim 5 wherein the body comprises a second port rail, the second port rail extending in a direction along a second port rail axis, the second port rail projecting in the port direction beyond a port facing surface of the port flange, the second port rail extending into the second port channel defined by the port cap wall.

7. The apparatus of claim 1 wherein:
the cap comprises a starboard shell and a port shell cooperating to define an entrance and the interior volume of the cap.

8. The apparatus of claim 7 wherein the cap comprises a front wall extending from the starboard shell to the port shell.

9. The apparatus of claim 1 wherein the cap comprises a top panel defining an aperture.

10. The apparatus of claim 8 wherein the port shell extends from a rear wall to the front wall of the cap.

11. The apparatus of claim 7 wherein the starboard shell comprises a plurality of starboard ribs.

12. The apparatus of claim 7 wherein the port shell comprises a plurality of port ribs.

13. The apparatus of claim 1 wherein the body comprises a front body wall extending from the starboard body wall portion to the port body wall portion.

14. The apparatus of claim 13 wherein the body comprises a rear body wall extending from the starboard body wall portion to the port body wall portion.

15. The apparatus of claim 1 wherein:
the starboard body wall portion extends from the rear body wall portion to a front body wall portion; and
the port body wall portion extends from the rear body wall portion to the front body wall portion.

16. The apparatus of claim 1 further comprising a guide pin disposed inside the interior volume defined by the cap, the guide pin having a forward end and a rearward end, the forward end of the guide pin being received in a forward starboard notch defined by the starboard shell and a forward port notch defined by the port shell, the rearward end of the guide pin being received in a rearward starboard notch defined by the starboard shell and a rearward port notch defined by the port shell.

17. The apparatus of claim 16 further comprising a plunger slidably supported by the guide pin, the plunger defining a bore and the guide pin extending through the bore so that the plunger is slidable along the guide pin.

18. The apparatus of claim 17 further including a spring seated against the plunger and acting to bias the plunger for movement, and wherein the plunger comprises a knob portion, the knob portion extending through an aperture defined by the cap, wherein a user can selectively move the plunger against a biasing force of the spring.

19. A magazine loader for loading cartridges in a rifle magazine, the magazine loader comprising:
a body having a pair of opposing forward and rearward wall portions and a pair of lateral wall portions, together defining a body interior and an open bottom sized to receive an upper end of the rifle magazine, a slot sized for receiving individual cartridges into the body interior, and a pair of slide guides with a slot;
a cap having four side wall portions defining a cap interior, the cap configured to be attached to the slide guides within the four side wall portions, the cap having a projection within the four side wall portions positioned for pushing a cartridge inserted into the rifle magazine when the rifle magazine is inserted into the open bottom of the body, the cap biased to an upward position by a pair of leaf springs engaged with the pair of slide guides;
the magazine loader further including a latch to hold the rifle magazine in positon relative to the body of the magazine loader.

20. The magazine loader of claim 19 , further comprising a rearward wall portion defining a first slit and a second slit, the rearward wall portion comprising a cantilevered beam of the latch disposed between the first slit and the second slit, the cantilevered beam having a fixed end and a free end, a blocking member being fixed to the cantilevered beam proximate the free end thereof, the blocking member comprising a projection
