1. Field of the Invention
The present invention relates, in the field of air guns, to a magazine ejector structure for air gun having a structure where a magazine is inserted into and removed from a magazine holding section of an air gun body, and in particular to a magazine ejector structure for an air gun that ejects (spits out) a magazine that has been provided with rotary clip (rotary cylinder, rotary magazine) in an end section of magazine body of a rectangular solid shape, from the air gun body.
2. Description of the Related Art
This type of conventional air gun magazine is constructed from a substantially magazine body of a rectangular solid shape provided with a rotary clip(s) at one or both ends, and this magazine is held in a magazine holding section formed from a cavity in the air gun body.
A magazine that has been inserted into the magazine holding section is ejected from the magazine holding section once all bullets contained in the rotary clip have been fired, and after reloading the empty a rotary clip with bullets it is fitted into the magazine holding section.
Conventionally, there is known an air gun of a structure having part or all of a magazine body of a magazine exposed from an opening of the air gun body (related art 1).
There is also known an air gun of a structure having a gap provided between a magazine holding section of the air gun body and the magazine body of the magazine, and dropping down under its own weight (related art 2).
However, with related art 1, if the section of the magazine body that is exposed from the air gun body is small, there is no effect, while conversely if a lot of the magazine body is exposed it is more likely that foreign bodies will become attached or infiltrate inside, and there is a problem that it is easy to cause damage. Further, if the magazine body of the magazine is exposed from the air gun, there is a problem that the external appearance is detrimentally affected.
Also, with related art 2, since a gap is provided between a magazine holding section of the air gun body and the magazine body of the magazine, there is a problem that the probability of operational malfunctions arising is high. There is also a possibility of the magazine not being able to drop under its own weight due to foreign matter infiltrating into the gap.
In order to solve the above-described problems, there is proposed, in an air gun having an air gun body and a magazine that is fitted into and removed from a magazine holding section of the air gun body, a magazine ejector structure, wherein
the magazine has a magazine body of a rectangular solid shape provided with a clip at at least one end; and
the magazine body comprises an ejector capable of moving in the longitudinal direction of the body;
an ejector elastic member, provided on the ejector member, capable of expanding and contracting between part of the ejector member and part of the magazine body; and
an engagement indent capable of engaging with a magazine catch when fitted to the air gun body, and
the air gun body comprises a magazine catch, urged by a catch elastic member into a holding space for fitting the magazine, and being capable of engaging with the engagement indent of the magazine; and
a stopper, projecting to the magazine holding section, capable of pressing part of the ejector member at the time of fitting the magazine.
According to the present invention, since it is possible to completely insert a magazine into the inside of a magazine holding section of the air gun, the magazine does not project from the air gun body and there is the effect that there is no problem with the external appearance.
Also, at the time of eject (spitting out), by removing a magazine catch, which is an engagement section, the magazine is ejected from the air gun body by the urging force of the elastic member, which means that there is no need to have a large gap between the magazine holding section of the air gun body and the magazine body of the magazine, and it can be made as small as possible. Accordingly there is the effect that the occurrence of operational malfunction and infiltration of foreign matter, which are the two drawbacks the related art 2, are both extremely unlikely compared to the related art.
Description will now be given based on
An air gun of an embodiment of the present invention is an air gun formed from a magazine M and an air gun body A. The magazine ejector structure of this embodiment of the invention will be described for the magazine M and the air gun body A. A magazine M that is freely detachable from the air gun body A that is the embodiment of the invention has a magazine body 1, formed from a rectangular solid shaped box body provided with a rotary clip 2 (rotary clips), provided on at least one end section, in this embodiment on both end sections. BB shot or pellet shot is loaded into each bores of the rotary clip 2.
The rectangular solid shaped magazine body 1 has an ejector member 4 capable of moving in a longitudinal direction internally, an ejector elastic member 5, provided on the ejector member 4 and capable of being compressed and expanded between part of the ejector member 4 and part of the magazine body 1, and an engagement indent 3 provided on a surface constituting a front side surface at the time of fitting to the air gun A, respectively provided two at a time in a symmetrical fashion facing in opposite directions on both sides, with the middle of the magazine body 1, in a longitudinal direction, as a center.
With this embodiment, the ejector member 4 is formed from a T-shaped member. The T-shaped member 4 is comprised of a rod-shaped T-support section 4b facing in the longitudinal direction of the magazine body 1, and a rod-shaped T-head section 4a facing in a width direction, with the T-support section 4b being capable of movement inside a movement path 6 provided in a longitudinal direction of the magazine body 1, and the T-head section 4 projecting from a side surface opening section 6a of the movement path 6 and being capable of movement.
With this embodiment, the ejector elastic member 5 is formed from a spring coil. The spring coil 5 is provided at the outer periphery of the rod-shaped T-support section 4b, with one end being in contact with the T-head section 4a, and the other end in contact with or fixed to part of the movement path 6 of the magazine body 1, and is configured so as to be capable of compression and expansion between the T-head section 4a and part of the movement path 6.
The air gun body A is provided with a magazine holding section 11, which is a holding space for loading the magazine M, at a muzzle side of the handle section 7. The magazine holding section 11 is provided with an opening section 12 in a lower end section of the handle section 7. The magazine holding section 11 is provided with a catch elastic member 10 at a muzzle side, and has a magazine catch 9 that is urged towards the rear by the catch elastic member 10, and a stopper 8 that projects from both side surfaces inside the magazine holding section 11.
The magazine catch 9 is a side surface L-shaped plate body, and as shown in
The catch elastic member 10 is formed from a spring coil in this embodiment, and urges the internal catch section 9a of the magazine catch 9 towards the rear of the magazine.
The stopper 8 is a projecting section projecting from left and right side surfaces of the magazine holding section 11, and is capable of pressing the ejector member 4 against the urging force of the ejector elastic member 5 by coming into contact with the T-shaped two end sections of the ejector member 4 when loading the magazine M.
Next, the embodiment of this invention will be described based on
BB shot or pellet shot are loaded into each bores of a rotary clip 2 which are at both end sections of the magazine M. Magagine M is inserted from an opening section 12 opening to a lower end of the handle section 7 into the magazine holding section 11 of the magazine body A. The magazine M can also be similarly inserted from either end section as it has a symmetrically identical structure about a center line in the longitudinal direction.
The magazine M has the magazine body 1 inserted into the magazine holding section 11 from the opening section 12, but a lateral clearance of the stopper 8 projecting in a protruding shape from the left and right side surfaces at halfway points is for passing the rotary clip 2, but is a clearance where contact is made from above with the T-head section 4a of the T-shaped member 4 that is the ejector member. The T-shaped member 4 can not go upwards from the position of the stopper 8, but the magazine body 1 is inserted in that state as far as the uppermost section (see
As shown in
Next, in the event that the magazine M is ejected from the air gun body A, the contestant etc. rotates the external catch section 9b of the magazine catch 9 downwards from outside the air gun body A, and if the internal catch section 9a is removed from the engagement indent 3 against the urging force of the catch elastic member 10 the ejector elastic member 5 is compressed by the stopper 8, and as a result the whole of the magazine body 1 is popped out by this urging force, and it is possible to remove the magazine M to the outside at that instant from the opening section 12.
