Description

Assembly device for aiming device on a hand gun

The invention relates to an assembly device for aiming device on a hand gun according to the preamble of claim 1.

An assembly device for an aiming device on a hand gun is known from US 4 205 473, in which two separate assembly parts of the same type or assembly parts of the same type combined in one rail, which have respectively a hollow space open at the top, are attached to a barrel of a hand gun. Two other assembly parts of the same type together form respectively an annular mounting for a telescope sight and have on their lower side, a rotatable clamping jaw which may be inserted in a certain angular position respectively from above into the hollow space of one of the weapon-side assembly parts and may be displaced by rotation by means of a lever engaged with a section of the surface of this hollow space. The assembly part, in which a telescopic sight is mounted, is thus clamped to the weapon-side assembly part. The accuracy of positioning of the telescopic sight with respect to the hand gun thus depends crucially on contact of the surfaces of the clamping jaw and of the hollow space in the clamped state, into which the latter move due to a movement in which they grind against one another which may lead to wear on repeated assembly and dismantling, as a result of which the repeat precision of positioning is impaired. US 2 624 946 discloses an assembly device for an aiming device on a hand gun with two assembly parts, of which a first is connected to a telescopic sight by means of a clamp and a second is firmly connected to the hand gun. The first assembly part has an opening, which is widened at the top essentially like a funnel, and the second assembly part has an engagement section which is widened at the top to be essentially cone-like. The opening and the engagement section are narrowed or cut off respectively at two opposite sides. If the opening is aligned coaxially to the engagement section, the first assembly part may be placed on the second assembly part in a certain angular position so that the engagement section projects into the opening. Due to subsequent rotation by 90°, the two assembly parts may be clamped positively to one another. However, the accuracy of positioning of the telescopic sight with respect to the hand gun here too depends crucially on contact of those surfaces of the two assembly parts which grind against one another during assembly and dismantling. Furthermore, for assembly and dismantling, the first assembly part together with the telescopic sight must be rotated by 90°.

The object of the invention is to provide an assembly device of the type mentioned in the introduction which facilitates attachment which is if possible clearance-free and has repeat precision during simple operation.

This object is achieved by an assembly device having the features of claim 1. Expedient designs and developments of the invention are the object of the sub-claims.

The invention is characterised in that for a generic assembly device, a cone is arranged in the opening of the coupling element of the first assembly part and a counter-cone matched thereto is formed in the pin of the second assembly part or vice versa, wherein the cone and the counter-cone are engaged with one another if the projections are engaged with the engagement sections. The first assembly part thus has a main body, with which a ring forming the coupling element is connected to be rotatable, and either the cone or the countercone is a section of a connecting link, by means of which the ring is connected to the main body of the first assembly part, and on which the ring is mounted to be rotatable.

Extremely precise positioning of the two assembly parts relative to one another is achieved via the centring action of the cone with the counter-cone without the conical surfaces having to grind against one another it they come in contact with one another, since for this only a purely axial movement is necessary. High aiming precision is thus facilitated even after repeated dismantling and renewed assembly of the aiming device. The elements moved against one another in grinding manner for clamping of the two assembly parts, namely the radial projections of the pin and the engagement sections, against which the projections are moved if the pin and the hollow space are rotated relative to one another, are not decisive for the accuracy of positioning of the two assembly parts relative to one another and hence also not for the accuracy of positioning of the aiming device with respect to the hand gun.

The rotatable ring alone realises the movable system element necessary for assembly and dismantling of the aiming device on or from the hand gun and permits simple manual implementation of these steps without using a tool. The connecting link fulfils a double function in the form of a single part, namely apart from centring of the two assembly parts with respect to one another in the assembled state, also the rotatable mounting of the ring.

For mounting of the ring on the connecting link, a thread is particularly advantageous, the direction of which on rotation of the ring into that position in which the projection of the pin engages with the engagement sections of the ring effects an axial movement of the ring in the direction of the main body. Such a thread combines in simple manner the function of pivoting of the projections of the pin to produce axial positive locking by engaging behind the engagement sections with the function of axial clamping of the pin and of the ring against one another.

As the connecting link is mounted to be rotatable on the main body, wherein the axes of rotation of the connecting link and of the ring are the same, and the connecting link can be fixed in a variable angular position on the main body by a releasable attachment element, the possibility is produced to adjust in simple manner, in particular without taking apart the first assembly part, the axial position of the ring with respect to the connecting link to ensure clearance-free resting of the cone of the connecting element on the counter-cone of the second assembly part with appropriate contact pressure.

For defined positioning of the main body with respect to the connecting element, pairing of a bearing pin and a recess matched to the latter is particularly suitable, wherein one of these elements is provided in the main body and the other in the connecting link. A screw, the shaft of which extends through an axial bore in the connecting link, and which is screwed into a threaded bore in the main body, the axis of which is the common axis of rotation of the connecting link and of the ring, is particularly suitable as an attachment element. This type of attachment of the connecting link to the main body may be loosened and then fixed again in particularly simple manner to adjust the axial position of the ring with respect to the connecting link.

The ring preferably has a stop which limits the angle of rotation relative to the main body in that direction of rotation which leads to engagement of the engagement section of the ring with the projections of the pin. A defined position of the projections of the pin with respect to the engagement sections of the ring and a defined contact force between the two assembly parts in the state clamped to one another is thus achieved.

Furthermore, the ring preferably also has a stop which limits the angle of rotation relative to the main body in that direction of rotation which removes engagement of the engagement sections of the ring with the projections of the pin. This makes it easier for the user during dismantling of the aiming device to find that position of the ring in which the ring may be removed from the pin and hence the aiming device may be removed from the hand gun. In addition, it is avoided that the user unintentionally rotates the ring in the dismantled state of the aiming device beyond this position and during renewed assembly on the weapon places it in an incorrect position on the pin which does not facilitate clearance-free centring of the first assembly part with respect to the second assembly part.

The stop may be formed in preferred manner by a stop pin projecting in axial direction from the ring on its outer peripheral surface and which at a limit of the angle of rotation range comes to rest on an outer surface of the main body. This realisation is particularly simple and allows the user trouble-free visual and/or tactile control of the two end positions of the ring. A single stop pin, which is arranged on the ring so that it comes to rest on a respective other point of an outer surface of the main body at each of the two limits of the angle of rotation range provided, may thus form the stop for both directions of rotation. However, it is also possible that for the two different directions of rotation, two separate stops, for example in the form of two separate stop pins spaced from one another peripherally on the ring, of which each comes to rest at a point assigned to it of an outer surface of the main body at respectively only one of the two limits of the angle of rotation range provided, are present.

It is possible that the first assembly part has a mounting for the aiming device and the second assembly part can be attached to the hand gun or is designed as a constituent of the same. Alternatively to this, the second assembly part may have a mounting for the aiming device and the first assembly part may be attached to the hand gun or may be designed as a constituent of the same.

Further unusual features and advantages of the invention can be seen from the following description of a preferred exemplary embodiment using the drawing. The following are shown:

An assembly device lof the invention can be seen in a perspective view in Figure 1. It consists of a first assembly part 2, which serves as a mounting for an aiming device not shown, such as in particular a telescopic sight, and of a second assembly part 3, which is attached to a hand gun 4, for example is screwed to the latter, of which in Figure 1 only a rearward part of the upper side of a barrel is indicated. As components of the first assembly part 2, a main body 5, a clamp 6 and a ring 7 can be seen in Figure 1. The clamp 6 can be connected to the main body 5 via clamping screws not shown and together with the main body 5 forms a mounting for an aiming device. Preferably, although not necessarily, two similar assembly devices 1 are arranged one after the other for attachment of an aiming device to the hand gun 4 along the barrel. The ring 7 serves for releasable connection of the first assembly part 2 to the second assembly part 3, which is illustrated below.

Figure 2 shows a central sectional view of an assembly device 1 of the invention in a plane lying vertical to the line of sight. As can be seen therein, the second assembly part 3, which rests with its underside on the hand gun 4 and is connected to the latter by a screw 8, has a pin 9 which extends upwards in the direction of the first assembly part 2. The arrangement of the assembly device 1 on the upper side of a hand gun 4, the barrel 4 of which is located in horizontal position, is the basis here of the use of the terms “upper” and “lower”. The pin 9 has a longitudinal axis 10 and several projections 11 protruding in radial direction at its upper end. In Figure 2, the pin 9 is inserted into an opening 12 formed in the ring 7.

Figure 3 shows a sectional view along the line A-A in Figure 2 and vertically to the viewing plane of Figure 2. There is located on the left side, a projection 11 in positive engagement with one of several engagement sections 13 of the ring 7, by means of which the opening 12at the lower end of the ring 7 is narrowed at several points along the periphery. The asymmetry of the upper end region of the pin 9 and of the opening 12 of the ring 7 in Figure 3 is based on the number provided in the exemplary embodiment shown of respectively three projections 11 and three engagement sections 13. On the right side no further projection 11 or engagement section 13 lies directly opposite the projection 11 which can be seen on the left and the associated engagement section 13 so that in Figure 3, the opening 12 on the right side is not filled and appears as hardly narrowed. However, in fact all three projections 11 of the pin 9 are respectively engaged with one of the three engagement sections 13 of the ring 7 so that positive locking is thus provided in axial direction between the ring 7 and the pin 9.

How the pin 9 may be inserted into the opening 12 of the ring 7 and may be displaced into the position shown in Figures 2 and 3, can be seen from Figures 4 and 5, in which the second assembly part 3 with the pin 9 or the ring 7 are shown in respectively two perspective views. As can be seen there, the shape of the opening 12 narrowed by the engagement sections 13 to the height thereof corresponds to the shape of the end section of the pin 9, on which the radial projections 11 are formed so that the pin 9 with the projections 11 may be inserted into the opening 12 past the engagement sections 13 in at least one angular position relative to the ring 7 if the ring 7 and the pin 9 are aligned with respect to one another so that their respective longitudinal axes 27 or 10 coincide with one another. The depth of the opening 12, the engagement sections 13 and the projections 11 in respectively axial direction are matched to one another so that the ring 7 and the pin 9 inserted into the latter may be rotated with respect to one another so that the projections 11 positively engage behind the engagement sections 13, as can be seen in Figure 3 on the left side.

Figures 6 and 7 show, for clarification, respectively sectional views along the line B-B in Figure 2, in which the ring 7 and the pin 9 are located in two different angle of rotation positions relative to one another. Figure 6 shows a position in which the projections 11 may be inserted into the opening 12 past the engagement sections 13. In this angular position, there is correspondence between the contours of the end section of the pin 9 with the projections 11 and the opening 12 limited at its entrance partly by the engagement sections 13 with a pre-determined clearance, which allows trouble-free insertion of the projections 11 into the opening 12. The projections then fit into the regions of the entrance of the opening 12 located between the engagement sections 13. It should be noted that in practice in fact the ring 7 is placed on the pin 9, since the latter is a constituent of the second assembly part 3 assembled firmly on the hand gun 4. However, it is a question only of the relative movement between the ring 7 and the pin 9 for the functioning of the assembly device 1.

Figure 7 shows that position in which the projections 11 engage behind respectively centrally the engagement sections 13. In the arrangement provided in the exemplary embodiment of respectively three equal projections 11 and three equal engagement sections 13 symmetrically along the periphery of the pin 9 or of the opening 12, the angle of rotation of the ring 7 during the transition from the position shown in Figure 6 to the position shown in Figure 7 is 60°. This angle of rotation of 60° can also be seen in Figures 6 and 7 at the different positions of the actuating lever 14 protruding radially from the ring 7. Due to the number of three projections 11 and three engagement sections 13 provided, the entrance of the opening 12 has an essentially triangular shape with rounded corners. However, only two projections 11 and correspondingly two engagement sections 13 could also be provided, or more than three projections 11 and an equal number of more than three engagement sections 13 could also be provided. The angle of rotation is always 180° divided by the number of projections 11.

As Figure 2 further shows, the ring 7 is connected by a thread 15to a connecting link 16 which constitutes a further constituent of the first assembly part 2 and in turn is connected to the main body 5 by a screw 17 which is screwed into a threaded bore 18 in the main body 5 of the first assembly part 2. Due to the thread 15, the ring 7 is mounted to be rotatable on its inner side on the outer side of the connecting link 16 and via the latter on the main body 5. The connecting link 16 is shown in Figure 8 in two different perspective views and has essentially the shape of a ring with a longitudinal axis 26 which is formed on one side as a cone 19 and on the opposite side has a hollow-cylindrical recess 20. In the assembled state according to Figure 2, a cylindrical extension 21 projecting centrally from the main body 5 engages in the recess 20 and thus fixes the position of the connecting link 16 with respect to the main body 5.

In the position of the pin 9 shown in Figures 2, 3 and 7, in which the projections 11 are engaged with the engagement sections 13, the cone 19 rests on a counter-cone 22 formed in the pin 9 by a conical opening on its end-face side. The axis of symmetry 26 of the cone 19 and hence of the connecting link 16 coincides in this position with the axis of symmetry of the counter-cone 22, which corresponds to the longitudinal axis 10 of the pin 9. Centring between the pin 9 and the connecting link 16and hence also defined relative positioning between the first assembly part 2 and the second assembly part 3 on the whole is thus effected in the position shown in Figures 2 and 3. This defined relative positioning is not restricted to the radial direction, that is, to coinciding of the axes 10 and 26, but it also includes the axial direction with respect to these axes 10 and 26.

The relative rotation between the pin 9 and the ring 7 for displacement of the assembly device of the invention into the position shown in Figures 2, 3 and 7 is effected after placing the first assembly part 2 on the second assembly part 3 in the angular position of the ring 7 shown in Figure 6 by subsequent rotation of the ring 7 by the user by means of the actuating lever 14. Mounting of the ring 7 on the connecting link 16 by the thread 15 thus ensures that the ring 7 during this rotation also executes an axial movement relative to the connecting link 16 with respect to the longitudinal axes 26 and 27 which correspond to one another, in which the projections 11 come in contact with the engagement sections 13, as a result of which the cone 19 with increasing angle of rotation of the ring 7 is pressed with increasing axial force against the counter-cone 22.

In order to guarantee that resting of the cone 19 on the counter-cone 22 in the connected state of the two assembly parts 2 and 3 is on the one hand clearance-free and there on the other hand excessive pressing is not effected, and on rotation of the ring 7, intense wear at the contact surfaces of the projections 11 and of the engagement sections 13 does not take place, the axial position of the ring 7 with respect to the connecting link 16 can be adjusted. For this the connecting link 16 has an inclined bore 23, which is visible in Figures 2 and 8, into which a pin can be inserted from the surface of the cone 19. After loosening of the screw 17, the connecting link 16 may be rotated about its longitudinal axis 26 by means of a pin inserted into the bore 23, as a result of which due to the mounting of the ring 7 via the thread 15, the axial position of the ring 7 changes with respect to the connecting link 16 if the ring 7 is fixed during rotation of the connecting link 16. After renewed tightening of the screw 17, the ring is then located in a different axial position than previously.

This adjustment of the axial position of the ring 7 must be carried out only during first assembly, but not during continuous use. If required, it may be carried out again later, for example to compensate for manufacturing tolerances if an aiming device provided with one or more first assembly parts 2 is to be used on a different hand gun 4 which is already provided with one or more second assembly parts 3, the dimensions of which deviate slightly depending on tolerance. No taking apart of the first assembly part 2 is thus advantageously necessary, but loosening of the screw 17 suffices.

In order to limit the angle of rotation of the ring 7 to precisely that range which is necessary to move the projections 11 back and forth between the position shown in Figure 6, in which they can be inserted into the opening 12 past the engagement sections 13, and the position shown in Figures 2, 3 and 7, in which they engage behind the engagement sections 13 centrally and touch them with appropriate compressive force, a stop pin 24 is integrally formed on the outer peripheral surface of the ring 7. The stop pin 24 touches a surface section 25 of the main body 5 at a respective other point in any of the end positions of the ring 7 shown in Figures 6 and 7.

Figure 1 shows the end position suitable for insertion of the projections 11 into the opening 12 of the ring 7 corresponding to Figure 6, in which the actuating lever 14 protrudes laterally from the hand gun 4 and the stop pin 24 rests on a point of the surface section 25 of the main body 5. To clamp the first assembly part 2 to the second assembly part 3, the actuating lever 14 is to be pivoted in the direction of the arrow 28 in Figure 1, wherein the stop pin 24is first of all removed from the surface section 25, then approaches the latter again and finally strikes against another point of the surface section 25 when the engagement sections 13 of the ring 7 have reached the end position shown in Figure 7.

In the exemplary embodiment described above, the first assembly part 2, to the constituents of which, inter alia, the main body 5, the ring 7, the connecting link 16 and the screw 17 belong, forms a mounting for the aiming device, and the second assembly part 3 with the pin 9 is attached to the hand gun 4. Equally, it would however also be possible to attach the first assembly part 2 to the hand gun 4, and to provide the second assembly part 3 with a mounting for the aiming device. It goes without saying that for this the shape of the main body 5 has to be adapted for attachment to the hand gun 4. In particular a one-sided extension of the main body 5 in the direction of the barrel of the hand gun 4, the design of bores for screws for attachment to the barrel and reduction of the width to the width of the barrel belong to the necessary measures. Furthermore, the shape of the second assembly part 3 must also be adapted, in particular to provide a support for the aiming device and mounting elements and attachment elements for the latter, such as for example a clamp as well as screw connections for attachment thereof. Such interchanging of the positions of the first and of the second assembly part 2 and 3 with respect to the arrangement on the hand gun 4 lies within the framework of the claimed invention.

Equally, it would also be possible to form the cone 19 on the end-face side of the pin 9 and the counter-cone 22 in the connecting link 16, which is arranged on the base of the opening 12. The arrangement of the recess 20 and of the extension 21 between the connecting linkl6 and the main body 5 could thus be interchanged in order to provide in the connecting link 16 adequate space for the counter-cone 22 which requires the formation of an opening. The positioning effect of the pairing comprising cone 19 and counter-cone 22 would also be provided in an interchanged arrangement of these two elements on the first and the second assembly part 2 or 3. Such modifications and comparable modifications, which the expert can see from the exemplary embodiment described, are a constituent of the invention if included by the scope of protection of the claims.
