Description

[Detailed Description of the Invention] The inquiry for attachment to a gun or the like is related to a tool.

For convenience, the present invention will be described with reference to attaching a sight to a rifle; however, it should be understood that the invention is not limited thereto.

In the past, various types of attachments have been proposed for use with rifles, and these attachments are typically screwed onto the rifle's firing device, while attachments are typically plate-mounted. A split ring clamp is used to secure it.

However, these prior art proposals have various disadvantages and often do not allow precise adjustment.

Moreover, these proposals are cumbersome to assemble and
Not useful for quick removal of sighting equipment.

Furthermore, the common design of prior art mounts is such that the recoil or internal forces of the firearm are transmitted to the sight through an adjustment screw that is not specifically designed for that purpose.

Improved attachment to guns and the like for easy, frequent and quick installation and removal of sighting devices or other accessories without affecting the precision adjustment of the device. It is one object of the present invention to obtain a tool.

According to the invention, the mounting, which is adapted to be fixed to the rifle and has a partially grooved part f'L7'c formed by a conical head, has a bung and a bung. It consists of a body portion having a freely receiving opening and an adjusting screw screwed through the body portion and adapted to engage and engage the opposite side of the stopper. , by loosening one adjusting screw and tightening the other one-section screw, the main body part can be adjusted relative to the stopper.
The adjustment screws also have conical end surfaces that engage the conical head of the stopper and thereby prevent tightening. When I did,
Equipment will be provided for inquiries regarding rifles or sticks, the body of which is adapted to be pulled over the rifle.

Preferably, the mounting device further comprises a mounting plate for securing the bung to the rifle, in which case the mounting plate is formed correspondingly to the bung to receive the bung. The stopper has an aperture which is arranged so that when the adjusting screw is tightened, the stopper is firmly attached to the mounting plate and the body portion is pulled onto the mounting plate.

In one preferred embodiment of the invention, the main body part of the mounting device is constituted by a first part of the split ring clip, and the mounting device also includes a split ring clip.
The ring φ includes a second portion of the clamp and means for securing the clamp portions together.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings showing embodiments thereof.

In the embodiment shown in FIGS. 1-6, the double clamp mounting includes a plate 10, which is secured to the rifle section by screws II. It is designed to be Installation is on the bottom of the board IO, /
3 is contoured (as can be clearly seen in Figures 1 and 5) to ensure a tight fit on the rifle.

Each clamp /4', /S is of the spring fist ring type and has a lower clamping part 16 and an upper cranking part 17, these parts /4'
! a, /7 are joined together by a clamp screw /II. When assembled, the mounting is such that it rests at right angles on the plate io.In the valley mounting, the boss it has a central a long open loco O and a side opening 21; -/l
It communicates with the central opening aO, and is also provided with a screw to receive the opposing adjustment screw 22a.

The lower crank part 16 is attached to the plate IO by means of a plug. As can best be seen in FIG. and,
It has a conical adjustment surface 2Jr and a cylindrical head knob. The mounting plate IO has an opening 30, and as shown in FIG.
The conical mounting is correspondingly shaped to accommodate the surface.

When the stopper 3 is in their correct position, 6 stoppers λ3
a cylindrical central portion of 26, a grooved core, a conical adjustment surface λg and a cylindrical head λ? The mountings project above the plate io (as seen in FIG. 6) and the mountings of the lower clamping part /6 are placed inside the openings -lO in the bosses /9. When the screws here and here a are tightened, their tapered end surfaces engage with the conical adjustment surface 2g of the stopper J, and once the conical mounting surface S is When the mounting is fully fitted into the correspondingly formed hole 30 of the plate io, a downward force is applied to the mounting boss 12.
Add it on top.

The stopper J is made from alloy steel in this example.
Subsequently, the hardening by heat treatment ensures that the n1 stopper 3 is not easily deformed under the action of the screws a.

The reaction force is transmitted to the lower clamp part L via the central part λ6 and the head knob, but both the central part roller and the head part 29 are clamped and attached by the boss/V. It engages the wall of the opening 20 therein. Stopper 3 and a few words are board i
The relatively large area of engagement between the two cranks helps transmit the recoil force, and both cranks /4t and /Z absorb the recoil.

The deviation can be adjusted by loosening one of the screws λ and λλa and tightening the other so that the lower clamp portion 16 moves laterally across the stopper 3. be achieved. The dimensions of the major axis of the aperture λO are chosen to allow maximum adjustment.

In the embodiment shown in FIGS. 1-6, the mounting has only one clamp, but in all other respects the mounting shown in FIGS. Similar to ingredients.

In other embodiments of the invention, the attachment plate (f) io is omitted and the attachment plate lθ is firmly attached to the rifle by screws, welding, rivets, or any other suitable means. Stick to it. In yet another embodiment of the invention, the mounting to be attached to the rifle is such that the body portion of the fixture has openings 0 and 21, and by means of a
Avoids the use of clamp rings.

It is understood that various other modifications may be made in details of design and construction without departing from the spirit of the invention.
