Description
[0001] The invention relates to a device for receiving a targeting device according to the preamble of claim 1. DE 20 2012 101602 U1 discloses a known device for receiving a targeting device on a base of a firearm with a mounting base body.
[0002] Devices for mounting aiming devices, such as sights, telescopic sights, or the like, are known, which are secured to the firearm by either quick-release mechanisms or simple screws. Quick-release mechanisms have the advantage of always generating a constant preload on the clamping mechanisms, thus guaranteeing a repeatable point of impact after removing and reattaching the aiming device. The main advantage here is that this can be done without additional tools. The disadvantage of this mechanism is that it must always be adjusted to the tolerances of the different bases. Therefore, use on multiple bases with the same design is only possible if the aiming device is re-zeroed after tolerance adjustment.
[0003] Simple screw connections allow for easy adjustment of the tolerances of different bases, but have the disadvantage that, in order to achieve a repeatable point of impact position, they must be tightened with an additional tool, such as a torque wrench.
[0004] Based on this state of the art, there is a great need for a device for mounting a sighting system whose clamping mechanism both compensates for any tolerances at the base of the firearm and ensures a consistently constant preload force. Furthermore, the device should be easy, quick, reliable, and tool-free to mount. In addition, the device should be inexpensive to manufacture, durable, and as compact and space-saving as possible. The background of the invention is that, in the field of digital and / or thermal sighting devices, there are those that allow different point-of-impact locations to be stored. The invention therefore aims to provide a device to overcome the aforementioned difficulties.
[0005] This task is solved in a surprisingly simple but effective way by a device for receiving a targeting device according to the teaching of the patent claims.
[0006] According to the invention, a device for mounting a sighting device on the base of a firearm is proposed, comprising a mounting base for the direct or indirect mounting of the sighting device and at least one fastening device for releasably attaching the device to the base. The fastening device includes at least one clamping element and at least one clamping screw, wherein the clamping element can be brought into contact with a clamping surface arranged on the base by means of the clamping screw in a force-fit and / or form-fit manner. The device is characterized in that the tightening torque of the clamping screw is adjustable and limited.
[0007] The invention is based on the fundamental principle that loosening the clamping screw of the fastening device does not alter its set limit, thus ensuring that the defined, consistent tightening torque is maintained even when the device is repeatedly attached to the base of a firearm. It has been recognized that the applied stresses remain constant during the mounting and remounting of the device on the base of the firearm, preventing any distortion of the firearm and eliminating the need for re-zeroing.
[0008] According to the invention, the device comprises a mounting base for the direct or indirect mounting of the aiming device. The mounting base has an upper mounting surface on which the aiming device is primarily mounted. Furthermore, the mounting base has a lower mounting surface, which preferably has a longitudinal recess. By means of this longitudinal recess, the lower mounting surface can be engaged with the corresponding base of the firearm along its longitudinal extent. Suitable measures and embodiments are subject to expert knowledge.
[0009] According to the invention, the device further comprises at least one, preferably two, three, four, five, six, or more fastening devices for releasably attaching the device to the base of the firearm, each fastening device comprising at least one, preferably two, three, four, five, six, or more clamping elements and at least one, preferably two, three, four, five, six, or more clamping screws. The fastening device is preferably arranged laterally on the mounting base. More preferably, the fastening device is designed as a clamping mechanism. Within the scope of the invention, the design, arrangement, and / or shape of the clamping element and / or the clamping screw is of secondary importance. Furthermore, it is of secondary importance whether the individual clamping elements and / or the individual clamping screws have the same or different designs, arrangements, and / or shapes.It is only important that the clamping element of the fastening device is designed to be movable in order to achieve optimal, in particular force-fit and / or form-fit, adaptation to the corresponding clamping surface of the base. It is known to those skilled in the art that the clamping element preferably extends substantially parallel to the longitudinal direction of the firearm, i.e., with only a slight, insignificant deviation, while the clamping screw is arranged substantially transversely to the longitudinal direction of the firearm, i.e., with only a slight, insignificant deviation. In this way, when the device is mounted on the firearm, the clamping screw presses on the clamping element in such a way that the clamping element can be brought into contact with the clamping surface of the firearm on the base in a force-fit and / or form-fit manner.
[0010] Within the scope of the invention, it has been recognized as essential that the tightening torque of the clamping screw is adjustable and limited. Preferably, the adjustable limitation of the tightening torque is achieved by a combination of a screw connection with, preferably integrated, torque limitation. Suitable measures and designs are subject to expert knowledge.
[0011] Furthermore, it has been recognized within the scope of the invention that, due to the adjustable limiting of the tightening torque, the device enables both the compensation of tolerances of similarly designed bases on different firearms and the simultaneous generation of a constant preload on the fastening device between the firearm and the mount, i.e., the receiver for the aiming device. This is achieved by the preferred combination of a screw connection with, preferably, an integrated torque limiter. It has also been recognized within the scope of the invention that the frictional engagement responsible for the preload of the fastening device is adjustable. Suitable measures and embodiments are subject to expert knowledge.
[0012] The device according to the invention thus makes it possible to achieve an adjustable limitation of the force and / or torque applied to the base of the firearm in a simple, quick, and reliable manner. The invention therefore makes it possible to use a sighting device with its associated mount, i.e., the mounting of the sighting device, on multiple bases and thus on multiple firearms with the same design. This allows for the adjustment of the base tolerances and ensures a constant preload for repeatable point-of-impact positioning.
[0013] Advantageous further developments of the invention, which can be implemented individually or in combination, are presented in the dependent claims.
[0014] According to the invention, the fastening device has a clamping lever, which is preferably designed to correspond to the clamping screw. In this way, it is possible to achieve a preload by means of frictional torque, whereby the torque of the clamping lever is transferred to the clamping screw.
[0015] According to the invention, the clamping screw has a first means and the clamping lever a second means, wherein the first means and the second means can be connected to each other by force and / or form locking. Due to this design of the first means on the clamping screw and the corresponding second means on the clamping lever, over-rotation of the clamping lever in the closing direction, i.e., in the closing direction, is achieved. It has been recognized within the scope of the invention that if the torque applied to the clamping lever exceeds the frictional torque generated by the preload, a relative movement occurs between the clamping lever and the clamping screw, and thus the torque acting on the clamping screw is reliably limited and remains constant.Furthermore, in the opening direction of rotation, i.e., in the opening direction, the screw connection of the clamping screw can be reliably opened by a positive locking effect created by the clamping screw and the clamping lever. This offers the advantage that even a stiff and / or stuck fastening device can be opened and thus released without tools at any time.
[0016] According to the invention, the first means and / or the second means is a bolt, a rotary bolt, a hook, a slide, a pawl, a wedge, a magnet, a groove, an edge, a recess, an eyelet, a projection, a notch, a latch, a stop, and / or a combination thereof. Preferably, at least one, more preferably two, three, four, five, six, seven, eight, nine, ten, or more first means and / or second means are included. This embodiment advantageously enables a stable and durable force-fit and / or form-fit connection between the first means and the second means. Preferred combinations of the first means and the second means are known to those skilled in the art.
[0017] Furthermore, it is conceivable that the fastening device has at least 1, preferably 2, 3, 4, 5, 6, 7, 8, 9, 10 or more spring elements by means of which the preload between the clamping lever and the clamping screw can be adjusted. Preferred embodiments of the spring element, for example as a spring such as a disc spring, and / or as a spring assembly such as a disc spring assembly, are known to those skilled in the art.
[0018] In another embodiment, it is conceivable that the fastening device includes an adjustment device by means of which the spring element can preferably be pre-tensioned and / or adjusted. Preferred embodiments of the adjustment device, for example as an adjusting screw, are known to those skilled in the art.
[0019] In a further development, it is conceivable that the device includes two fastening devices in order to distribute the forces and / or moments introduced for the purpose of fastening the device to the base of the firearm evenly, in order to simultaneously achieve a stable, reliable and secure hold of the device on the firearm.
[0020] Furthermore, it is conceivable that the fastening device has a closing direction, wherein a force-fit in the closing direction generates a torque transmission, preferably between the clamping lever and the clamping screw. In this way, the torque acting on the clamping screw is reliably limited and remains constant. The closing direction of the device is preferably adjustable, so that the closing direction can be clockwise or counterclockwise.
[0021] Furthermore, it is conceivable that the fastening device has an opening direction, whereby a positive locking mechanism achieves torque transmission in the opening direction, preferably between the clamping lever and the clamping screw. This allows the device to be released easily, quickly, and without tools at any time. This is particularly advantageous if the device is stiff and / or stuck. The opening direction of the fastening device is preferably adjustable and designed to correspond to the closing direction of the fastening device, so that the opening direction in a leftward rotation corresponds to the closing direction in a rightward rotation, and vice versa.
[0022] It is also conceivable that the firearm is a hunting and / or sporting weapon. Such firearms are familiar to a specialist.
[0023] Alternatively, the aiming device could be a sighting optic, a telescopic sight, and / or a combination thereof. Such aiming devices are familiar to those skilled in the art. It is assumed that the definitions and explanations of the terms mentioned above apply to all aspects described below, unless otherwise stated.
[0024] Further details, features, and advantages of the invention will become apparent from the following description of the preferred embodiments in conjunction with the dependent claims. The respective features can be implemented individually or in combination with one another. The invention is not limited to the embodiments. The embodiments are shown schematically in the figures. Identical reference numerals in the individual figures denote identical or functionally equivalent elements, or elements that correspond to one another with respect to their function.
[0025] Specifically, we show: Fig. 1 an isometric representation of a device according to the invention; Fig. 2 an exploded view of the device according to the invention; and Fig. 3 a detailed view of the fastening device according to the invention.
[0026] Fig. 1 Figure 1 shows an embodiment of a complete assembly according to the invention with a mounting base body 1, the fastening device 2 of which is designed in the form of a clamping mechanism, serves to lock onto a base of a firearm and has a mounting top 3 for receiving a sighting device not shown.
[0027] Fig. 2 shows the embodiment according to Fig. 1 as an exploded view of the complete assembly according to the invention with the individual components of the fastening device, which is designed in the form of a clamping mechanism and whose design according to the invention includes a torque limiter. A clamping screw 4 has the task of positioning and pre-tensioning the clamping element 8, designed as a clamping jaw, against the corresponding clamping surface of the weapon-side base. A constant pre-tension is of essential importance here. This is also achieved by the clamping lever 5, which has a corresponding design to the clamping screw 4. Due to a pre-tension (friction), this design allows the torque of the clamping lever 5 to be transmitted to the clamping screw 4. The pre-tension between the clamping lever 5 and the clamping screw 4 is provided by a disc spring or similar element.a spring element 6 designed as a disc spring package is generated, which can be pre-tensioned and adjusted by means of the adjusting device 7 designed as an adjusting screw.
[0028] Fig. 3 shows a detailed view of the embodiment according to Fig. 1 and 2, in which the fastening device is designed as a clamping mechanism with torque limitation. The design of the first means 9 on the clamping screw 4 allows the clamping lever 5 to be over-rotated when turning in the closing direction. When turning in the opening direction, a positive locking mechanism between the clamping screw 4 and the clamping lever 5 ensures reliable opening of the screw connection of the clamping screw 4. For this purpose, a corresponding second means 10 is also provided on the clamping lever 5, in this case as corresponding mating surfaces to the design of the first means 9. When turning in the closing direction, two inclined surfaces interact, which, due to the inclined plane, allow force transmission through friction.If the torque applied to the clamping lever 5 exceeds the frictional torque generated by the preload, a relative movement takes place between the clamping lever 5 and the clamping screw 4, reliably and constantly limiting the torque on the clamping screw 4.
