Definitions

  • the present invention relates to an assembly device between two parts to be coupled and uncoupled without special tools.
  • this assembly device is provided for assembling two pieces, one of which has a skirt extending in the assembled position to inside a cavity in the other room.
  • the present invention relates more particularly to a housing of waterproof watch or not in which the assembly of the middle and the back is obtained by an elastic segment.
  • This known waterproof watch case has major drawbacks. Firstly the fact of having to adjust the angular position of the bottom relative to the middle before being able to fit them. Second, having to proceed on the middle part with complicated machining, in particular the oblique groove. Finally the causes the segment to be taut in the tightly closed position of the box, which causes accelerated fatigue in this segment.
  • the object of the present invention is the production of a watch case in which the bottom assembly on the middle is formed by an elastic segment but which overcomes the aforementioned drawbacks, that is to say, or the establishment of the bottom in the build can be done in any relative angular position of these two pieces, where the machining is simple to carry out and or the elastic segment is in the rest position, not stretched, when the housing is in the closed position.
  • the present invention relates to an assembly device in particular for a watch case, comprising a middle and a back assembled by a elastic segment which is distinguished by the characteristics set out in claim 1 and dependent claims.
  • This assembly of the back 3 on the middle part-glasses is carried out as is will see in detail in what follows using an elastic segment in a material to shape memory.
  • the middle-bezel 1 is provided with a circular groove 4 opening into the internal housing thereof intended to receive part of the bottom 3.
  • This groove circular 4 is arranged in a plane perpendicular to the axis of symmetry of the middle-bezel and is therefore easily machinable.
  • This circular groove 4 is intended to receive the peripheral part of an elastic segment 5 made of a material with shape memory.
  • This elastic segment 5 has an outer periphery located on a circle with a diameter less than that of the bottom of the groove 4 of the middle but greater than the diameter of the recess 6 into which this groove 4 opens. Thus in the rest position of the elastic segment 5 it is partially housed in this circular groove 4. This segment is open so that it can expand elastically radially under the action of a pushing force radial.
  • This segment 5 has bosses 7 having the general shape of inclined faces and forming a succession of teeth or notches 8. When the elastic segment 5 is in position in the groove circular of the middle-bezel 1 the bosses 7 of the segment 5 protrude into the housing 6 of the middle-bezel 1 and therefore out of the groove 4 thereof.
  • This elastic segment 5 has the distinction of being located in a plane to low temperature, of the order of -20 to -50 ° C, the bosses 7 being in the extension of the peripheral part of the segment. On the other hand at temperature ambient, from 0 ° to 20 ° C and above, the bosses 7 fold upwards along lines 9 under the action of the shape memory of the material forming the segment 5 and these bosses are then located outside the plane defined by the peripheral part of the segment 5.
  • the underside of the middle-bezel 1 has a circular recess 10 with a flat bottom in which the peripheral part 13 of the bottom 3 is housed.
  • this peripheral part of the bottom 3 has a flat face provided with an annular groove 11 receiving an O-ring seal 12 which in the closed position of the case is crushed against the underside of the middle part-bezel 1.
  • the bottom 3 also has a cylindrical skirt 14 extending in position closing the case in the middle-bezel 1 and ending in one side inclined annular 15.
  • This skirt 14 is provided with countersinks 16, the number of which is equal to the number of bosses 7 of the elastic segment 5, intended to receive these bosses 7 to maintain the bottom 3 in the closed position of the housing.
  • the middle part 1 and the segment are refrigerated. elastic 2 so that the bosses 7 are positioned in the plane of the part segment 5 device.
  • the force of application or tightening of the base 3 on the middle-bezel 1 depends only on construction characteristics such as dimensions the back 3, the middle-bezel 1 and the segment 5 as well as the characteristics elastic of the bosses 7 of this segment 5. This clamping force can thus be defined once and for all and does not depend on manual operations such as screw tightening etc.
  • the machining is simple and easy to carry out, in particular the groove circular 4 of the middle-bezel 1 which is perpendicular to the axis of symmetry of this middle-bezel.
  • the clamping force of the back against the middle-bezel is completely determined by the characteristics of the parts of the assembly and does not depend a screw tightening force or other fastening device.
  • segment 5 To use connecting parts, here segment 5, in the rest position guaranteed their function over time. If we put an element in tension, it will have necessarily fatigue effects. This fatigue is not acceptable in a element such as the background. In addition, when a part is tensioned for a blocking, the friction between the two parts in contact must be greater than the force given by the segment under tension. If this condition is not respected, the bottom will always tend to open.
  • this assembly device can be used elsewhere than in a watch case. It allows in particular to assemble two parts, one of which has a skirt which in the assembled position is located inside a cavity that the other room has.
