[0001] This utility model relates to a sliding hook to lock and unlock pistol magazines
and in particular to a reversible hook for said purpose.
[0002] In the field of pistols different kinds of hooks designed for the locking and unlocking
of the magazine placed in the pistol grip are already known. In fact, a sliding lock
hook is known, which is placed and transversally guided with respect to the seat of
the magazine and fitted with a tooth designed to interact with a slot on one side
of the magazine. This type of hook is however unidirectional and non-reversible as
it can be assembled and operated in one direction only.
[0003] In addition, patent N. 1,090,108 filed by the same applicant discloses a sliding
hook for magazines to be used either as right hand hook or as left hand hook and
which is thus suitable both for righthanded and lefthanded shots. To change its position
said reversible hook is pressure mounted and dismounted, but its structure is quite
complex and sophisticated.
[0004] The purpose of this invention is instead to propose a reversible sliding hook to
lock and unlock pistol magazines, which is simple, easy to handle, to assemble and
disassemble.
[0005] For this purpose, a reversible hook for pistol magazines as specified in Claim 1
is proposed. The structural details of the proposed hook will be more apparent from
the description given hereinafter with reference to the accompanying drawing in which:
Figure 1 is a schematic and perspective view of a pistol with exploded hook: and
Figures 2 and 3 show a partial horizontal section of a pistol with righthand and lefthand
hook respectively.
[0006] In said drawing a pistol with shaft (10) and grip (11) is shown, with a magazine
(13) lodged in a seat (12) inside said grip. The magazine (13) is fitted, in a known
manner, with two slots (14), (15), one on each side, either one or the other of said
slots engaging the proposed locking hook (16).
[0007] In particular, inside grip (11) we have: a through hole (17) transversal to seat
(12) of magazine (13), two lateral openings (18, 19) flush with the ends of said through
hole (17) and crossing said seat (12); and two coaxial blind holes (20, 21) parallel
to through hole (17) and open on the opposite sides of grip (11).
[0008] Hook (16) is composed of a shank (22) fitted with a pawl (23) bearing a tooth (24)
at one end, while on its opposite end a pushing device (26) is fixed by means of a
removable pin (25). The shape of both said pawl (23) and pushing device (26) is corresponding
to lateral openings (18, 19)in pistol grip (11) and in the inner face of the pushing
device (26) a recess (27) is made available for a prestressed spring (28) mounted
inside a blind hole (20)or (21) in the grip.
[0009] As a matter of fact, to assemble the locking hook (16) its shaft (22) is introduced
into the through hole (17) in grip (11) in such a way that its pawl (23), (24) is
protruding either into slot (14) or into slot (15) in magazine (13) depending on the
position, right or left hand, required. After that, the pushing device (26) is fixed
to the free end of shaft (22) by means of pin (25) after having fitted spring (28)
between device (26) and the opposite blind hole (20) or (21). Now the locking hook
(16) is ready for use to lock and unlock the magazine, with pawl (23) and its front
tooth (24) fitted either to its left hand side or to its right hand side, as shown
in Figures 2 and 3 respectively. In both cases spring (28) will take and maintain
the hook in locking position: to release the hook and hence the magazine in order
to remove it from the grip, it is necessary to push in the device (26) in opposition
to spring (28).
[0010] It is evident that the hook (16) may be dismounted any time to be reassembled in
its opposite position as will be required by the user of the pistol. To do so it is
enough to take off pin(25), remove the pushing device (26) and then extract the shaft
(22)with pawl (23) from one side of the grip to reinsert it in the opposite side,
after fitting spring (28) into its seat, and fix pushing device (26) on the opposite
end of shaft (22) by means of pin (25).
1) Sliding hook to lock the magazine of pistols with a grip comprising a seat for
a magazine (13), a through hole (17) transversally directed to said seat and two lateral
openings (18, 19) flush with the ends of said through hole and crossing said seat
on correspondence with two slots (14, 15) on the opposite sides of said magazine,
characterized by a shaft (22) to be introduced and slide in through hole (17), a pawl (23) fixed
to one end of said shaft being fitted with a frontal tooth (24) engaging either one
or the other lateral slot (14 or 15) of the magazine through the corresponding opening
(18 or 19), by a pushing device (26) removably fitted to the opposite end of said
shaft so as to project from the opposite opening (19 or 18), and by a spring (28)
to keep the pawl with locking tooth (23,24) in the position required to lock in the
magazine, the magazine being released by acting on pushing device (26) in opposition
to spring (28).
2. Locking hook as claimed in claim 1, in which said pushing device (26) is fitted
to shaft (22) by means of a removable pin (25).
3. Locking hook as claimed in claims 1 and 2, in which spring (28) is placed between
the pushing device (26) and in one of the two opposite blind holes (20,21) made available
on the opposite sides of the grip and parallel to through hole (17).
4. Locking hook as claimed in the preceding claims, in which after detaching the pushing
device from shaft (22), said shaft with locking pawl (23, 24) can be fitted into its
opposite seat thus obtaining the easy reversibility of the locking hook itself.
