Definitions

  • the present invention relates to a coupling device for interconnecting two apparatuses, for example two sight units in an optical system, the coupling device including at least three anchorage points for interconnection of the two apparatuses.
  • One example of an optical system which places the above-mentioned demands is a daylight sight which should rapidly be capable of being supplemented so as to be operative in darkness by the application of an IR sight portion.
  • These two sights should be capable of being interconnected by means of a couple of manual manoeuvres such that:
  • the angular guiding of the apparatuses is affected with superior accuracy, for example better than 0.1 mrad (repetition accuracy);
  • the positional guiding of the apparatuses is effected at a certain accuracy, for example better than 0.5 mm;
  • the clamping forces may be controlled in size and direction so that deformations hazardous to the apparatuses are avoided.
  • a coupling device which satisfies the above conditions is characterized in that the first and second anchorage points are realized by cooperation between seat members disposed on the one apparatus and provided with first engagement portions, and sleeve means disposed on the second apparatus and provided with second engagement portions, the first engagement portions being turned to face outwardly and the second engagement portions being turned to face inwardly, or vice versa, and the sleeve members being disposed on a first shaft provided on the second apparatus, at least one of the sleeve members being displaceably disposed on the shaft in the longitudinal direction thereof for realizing engagement between the second engagement portions of the sleeve members and the first engagement portions of the seat members by clamping effect under displacement of the above-mentioned displaceable sleeve member on the shaft.
  • the seat members consist of V blocks. The V con igur tion gives a simple and reliable guiding ot the first shaft.
  • the first engagement portions of the e t members consist of conical surface sections and, according to yet a further advantageous embodiment of the coupling device, the second engagement portions of the sleeve members consist of conical surfaces.
  • Conical surfaces provide good contact between sleeve and seat members, at the same time as the apparatuses may unrestrictedly be rotated in relation to one another about the first shaft.
  • the third anchorage point is advantageously realized by snap connection between the two apparatuses.
  • the snap connection consists of a pin permanently disposed in the one apparatus and co-operating with an abutment disposed in the second apparatus and provided with a resilient locking flap, the locking flap displaying such geometry as to make for self-locking operation.
  • the displacement of at least one sleeve member on the first shaft may, according to one preferred embodiment, be realized by means of a handle provided with arrest means.
  • the handle is rotatably secured with its one end in one end of the above- mentioned first shaft and is rotary about a second shaft at right angles to the longitudinal direction of the first shaft, the handle being provided with arrest means which more or less restrict the movement of the sleeve member disposed on the first shaft most proximal to handle, along the longitudinal direction of the shaft in dependence upon the position of the handle.
  • one of the sleeve members may, according to one embodiment, be spring-biased on the first shaft.
  • Fig. 1 schematically illustrates a view partly in section of a coupling device according to the invention foi interconnecting two apparatuses

  • the coupling device 1 illustrated in Figs. 1-3 is intended to interconnect two apparatuses 2, 3.
  • the one apparatus 2 is provided with two facing V blocks 4, 5 having a common centre axis and disposed on the casing of the apparatus 2.
  • a conical section 6, 7 is provided in each V block.
  • the conical sections are turned to face outwardly in relation to the casing of the apparatus.
  • a shaft 8 is disposed on the second apparatus 3.
  • the shaft 8 carries a sleeve 9, 10 at each end.
  • the mutually facing parts of the sleeves 9, 10 display conical configuration for co-operation with the conical sections 6, 7 of the V blocks.
  • the sleeve 9 is displaceable on the shaft 8.
  • the sleeve 10 is placed under tension by means of a spring 13 which acts between the sleeve 10 and the associated end of the shaft 8.
  • the handle 11 may be rotated between an open position or unlocked state and a locked state. In its open state, the handle assumes a position such that the sleeve 9 co-operates with a section 14a on the arrest means 14 of the handle 11 and the longitudinal direction of the handle approaches the longitudinal direction of the shaft 8.
  • the handle In its locked state, the handle assumes a position with the longitudinal direction of the handle at right angles to the longitudinal direction of the shaft 8, and the sleeve 9 co-operates with the top section 14b of the arrest means 14.
  • a thickened portion (not shown) of the shaft may function as an arrest means for the sleeve 10
  • a spring (not shown) may be provided to act on the sleeve 9.
  • the shaft 8 of the apparatus 3 is disposed in the V configuration of the V block, which assists in guiding in the two apparatuses into mutually correct position for interconnection.
  • the handle 11 When the shaft 8 has assumed its position in the V block, the handle 11 is rotated through roughly 90 about the shaft 12 to the locked state illustrated in Fig. 3. During the rotation, the sleeve 9 is displaced towards the sleeve 10 under guidance by the arrest means 14 of: the handle 11. Contact and clamping action occur between the conical sections of the V block and the conical configura ion of corresponding sleeves. In this way, two anchorage points have been realized at the same time as it is still possible to rotate the apparatuses in relation to one another about the shaft 8 through the anchorage point.
  • the third anchorage points consists of a portion projecting from the one apparatus 2 in the form of a pin 15 for co-operation with an abutment 16 with a resilient locking flap 17 in the second apparatus 3.
  • the locking flap is rotary about a shaft 18.
  • a spring (not shown) strives to turn the locking flap in a direction counter to the arrow 19.
  • Figs. 4 and 5 show examples of other versions of the V block 5 and sleeve 10 included in the coupling device. Instead of conical configuration, either the V block or the sleeve has been given different configuration.
  • the periphery of the sleeve displays a bead 20 which is in contact with the conical section 7 of the V block.
  • the design according to Fig. 5 shows a bead 21 disposed in the V block 5 for co-operation with the conical configuration of the sleeve 10.
  • V block and sleeve may be established by surface contact, such as in conical surfaces, but linear or punctifor contact are possible alternatives.

Abstract

L'invention concerne un dispositif d'accouplement (1) comportant au moins trois points d'ancrage permettant l'interconnexion de deux appareils (2, 3), tel que des unités de visée dans us système optique. Dans le dispositif selon l'invention, un dispositif d'accouplement (1) est prévu permettant d'interconnecter de manière répétée deux appareils (2, 3) même sujets et sensibles à la déformation avec une très grande précision. Un premier et un deuxième point d'encrage sont créés par coopération entre des éléments d'appui (4, 5) dotés de premières parties de contact (6, 7) prévus sur un des appareils, et des manchons (9, 10) dotés de deuxièmes parties de contact sont prévus sur le deuxième appareil. Les manchons (9, 10) sont prévus sur un axe (8) monté sur le deuxième appareil (3), au moins un des deux manchons (9) étant monté mobile sur ledit axe (8) de manière à permettre le contact entre les deuxièmes parties de contact des manchons et les premières parties de contact (6, 7) des éléments d'appui par un effet de serrage dû au déplacement dudit manchon mobile (9) sur l'axe (8).
