ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fixture for a pistol accessory, and in particular to a fixture for quickly clipping an accessory on to a pistol.
2. Description of the Prior Art
The conventional fixing rack for a pistol accessory is normally used to secure a pistol accessory on the trigger guard of a pistol. Referring to
FIGS. 1 and 2
, a conventional fixing rack comprises a fixing base
12
, a fixing sheath
16
and a connecting plate
14
. The fixing base
12
has an L-shaped base plate
122
and an arc body
124
that are connected by a bridge element
126
. A space
123
is disposed between the L-shaped base plate
122
and the arc body
124
. A plurality of threaded holes
125
are positioned at the flank sides of the L-shaped base plate
122
and the arc body
124
, and another threaded hole
127
adapted to receive a short bolt
128
is also positioned at the short edge of the L-shaped base plate
122
. A plurality of round holes
145
, aligned with the threaded holes
125
that are positioned at the flank sides of the L-shaped base plate
122
and the arc body
124
, are positioned on the connecting plate
14
in order to connect and fix the connecting plate
14
to the fixing base
12
. A circular through hole
162
, having a longitudinally cut groove
164
therein, is disposed in the fixing sheath
16
, with one end of the cut groove
164
transitioning to a curved groove
166
that is perpendicular to the cut grove
164
. A plurality of threaded holes
168
and
167
are positioned along the bottom of the fixing sheath
16
. A laser sight (not shown) can be inserted in the circular through hole
162
, and a bolt
184
can be screwed into the hole
168
to secure the laser sight tightly in the circular through hole
162
because the existence of the cut groove
164
allows the cylindrical body of the sheath
16
to be flexed inwardly to clamp the laser sight when the bolt
184
is screwed tightly inside the hole
168
. In addition, the sheath
16
can be secured to the fixing base
12
by securing bolts
182
through the holes
167
and into aligned holes
125
on the L-shaped base plate
122
.
In use, the trigger guard
25
of a pistol
20
is inserted into the space
123
of the fixing base
12
, and then the connecting plate
14
is secured to the L-shaped base plate
122
via the bolts
182
, the openings
145
and the holes
125
. After that, the short bolt
128
is screwed into the hole
127
to press tightly against the trigger guard
25
so that the arc body
124
and the short bolt
128
can clamp the trigger guard
25
so as to prevent the fixing rack from shaking.
Unfortunately, the fixing base
12
of the conventional fixing rack described above is locked on the trigger guard
25
of the pistol
20
. This makes it not only inconvenient to assemble and disassemble, but also limits the space inside the trigger guard, hindering a user's finger during operation of the pistol. Additionally, not all front ends of trigger guards of pistols are perpendicular and smooth, so the axial line of the fixing base
12
will deviate from the sight line, making it difficult obtain an accurate aim.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a fixture for a pistol accessory that is easy to assemble and disassemble from the pistol.
It is another object of the present invention to provide a fixture for a pistol accessory that assures that the axial line of the fixture is aligned with the sight line of the pistol.
It is yet another object of the present invention to provide a fixture for a pistol accessory that can be tightly secured to the pistol during use to prevent the fixture from shaking or misalignment.
The objects of the present invention can be accomplished by providing a fixing rack for use in quickly clipping an accessory on to a pistol. The fixing rack has an elastic clipping seat made of an elastic sheet having two opposing sides that are bent upwardly and inwardly to a preset angle, each side having an inwardly-extending flange, and the two flanges defining an opening therebetween that varies in width when the sides are flexed. The fixing rack also includes two releasing plates, each releasing plate attached to one of the two sides of the elastic sheet to flex the two sides. The fixing rack also includes a fixing sheath attached below the clipping seat, the fixing sheath having a chamber for receiving a pistol accessory. The fixing rack can be quickly and conveniently attached to a pistol by flexing the releasing plates to widen the opening between the flanges, thereby allowing the flanges to be slid into corresponding wedging grooves in a pistol.
In accordance with another embodiment of the present invention, the fixing rack has an elastic clipping seat made of an elastic sheet having two opposing sides that are bent upwardly and inwardly to a preset angle.

Each releasing plate is attached to one of the two sides of the elastic sheet to flex the two sides. The fixing rack also includes a fixing sheath attached below the clipping seat, the fixing sheath having a chamber for receiving a pistol accessory. The fixing rack can be quickly and conveniently attached to a pistol by flexing the releasing plates to widen the opening between the flanges, thereby allowing the flanges to be slid into corresponding wedging grooves in a pistol.
