Description

GUNSIGHTS MOUNTED ON A PART OP A WEAPON ESPECIALLY A MORTAR This invention relates to a gunsight mountin for attachment to part of a especially a Such mounting carries telescopic and generally includes means b which the telescopic sight can be adjusted through the three spatial the sight being connected to part of a The mounting is o ten of the type can be thrust on to the for by means of a In this care must be taken that the so does not become loose as a result of shocks weapo is this a mounting has been provided havin a which bears by spring pressure on the part of the weapon on to which the mounting is In the known locking there is a danger that the massive movements o the weapon arising during firing have such effect on the locking part that the pressure exerted by the spring can be that it becomes effeotive against the said Because of there insufficiently immovable positioning of the mounting on the An object of the invention to provide locking of gunsight mounting on a especially a in such a way that it is not affected by movements arising during of the According to the invention a gunsight mounting for spring pressure on part of the weapon on the gunsight to be said being fixedly anchored with one end and engaged in bore of the rotatable pin with other end and said pin being provided at its free end locking of the gunsight on the weapon is In addition locking unlocking can be easily carried and the gunsight mounting can be easily and quickly mounted on the and withdrawn from It is also possible to increase considerably force exerted b the without incurring additional constructional An embodiment of the inventio will now be described by way of with reference to the accompanying in 1 is a front of a gunsight mounting according to the present 2 section on line of and 4 are detailed 5 is a section on the line of with parts and to 8 are detailed Referrin to th a gunsight mounting 1 has a part can on to a 2 of a for example a a casin 4 rotatably mounted on the part 3 means of an intermediate part 5 and a screw The part 3 is rotatably mounted on a hollow bush 4a of casing and a worm 7 having a knob Θ engages a worm wheel 9 provided on the part The intermediate part 5 is rigidly fixed to the casing by screws The casing 4 cylindrical part 4b whose is vertical to that of the part Another which by a worm 12 having a knob around the cylinder rests cylinder The provided with a conical portion in which another holder 14 is set under and which a telescopic sight 15 is The part 3 of the mounting 1 engages with the part of the weapon in the following The t 3 has converging side walls which engage a corresponding groove 17 on the weapon Thus the part 3 pushed from above into the groove With a part the part 3 engages between the casing 4 and the part which serves as a guide upon rotation of casing 4 around axis of the part upon turning of the worm which engages in the threads 9 which on part part 3 has a cylindrical through opening A rotatable pin 20 is located in the longitudinal medial plane 19 between the side walls 16 of the part the lowe end of the pin 20 engaging in a hole 21 in the part The pin 20 is provided with a cam 22 of which an upper surface 22a can engage in a recess 2a in the part 2 of the weapon in order to lock A part 20a of the 20 is located in the part 3 by an insert which is held fast by screws 24 to the part A torsion spring 25 is provided on to pin the lower end 25a of the spring 25 engaging in a hole 26 in the part while the upper end which is bent over in the axial engages in a hole 21 in the cam The pin 20 is constantly held in the safety position by torsion spring A handle 28 is provided at the uppe end 20b of the pin and is connected thereto by a pin 29 in a hole in the handle The cam 22 can be adjusted axially of the the pin 20 having a threaded portion 20c to this on which cam 22 is The cam 22 is locked on the 20 by a 22b engaging a longitudinal groove 20d in threaded portion In order to attach the mounting 1 to the part 2 of the weapon by sliding the side walls 16 in the groove 17 of the cam 22 on the 20 pivoted by of handle so that the cam 22 an opening 3b in the part end therefore clear of weapon the lowest position of the mounting 1 whe attached to the the handle 28 is Under the aotion of the torsion spring the pin 20 can thus engage with cam 22 in a corresponding opening 20 in the so that secure between mounting 1 and the weapon longitudinally alon the cam 22 of the pin 20 is turned by means of the handle against the actio of spring into the opening whereupon mounting 1 can be removed from the insufficientOCRQuality
