Definitions

  • the invention relates to watch cases with one or more pushbuttons, such as are required for the actuation of controllable elements of the clockwork in both mechanical and electric clocks, in order to perform a wide variety of functions, such as time stop devices in stopwatches or display switching in electric clocks Taxes.
  • the invention relates in particular to watch cases with pushbuttons of the type mentioned above, which have a button body with a large pressure area, primarily with a button body which is arranged in a recess in the housing wall and is flush with the outer surface or only insignificantly above it protrudes.
  • Watch cases with push buttons are known in a variety of forms. They are usually used to control actuation impacts In which can be displaced against spring pressure and which can be displaced in a substantially radial direction with respect to a circular housing wall.
  • the actuating push l is slidably mounted in the housing wall and carries a key body.
  • the guidance in the housing wall is only very short, and guidance difficulties therefore arise in particular with large key bodies.
  • the key body moves on an arc when it is actuated and consequently exerts not only pressure but also thrust forces on an actuating plunger controlled by it.
  • the pushbutton body in the opening or recess of the housing wall does not shift parallel to itself, unsightly, uncoverable gaps arise between the pushbutton body and the housing wall when the pushbutton is pressed.
  • the key body is connected to the housing wall via links, at least two of which are rigidly connected to one another, with a further element ensuring a plane-parallel displacement of the pressure surface of the key - gesture l it is.
  • the effort to be incurred in the latter embodiment is still considered too high and the object of the invention is therefore to create a watch case with pushbuttons of the type mentioned above, in which a precise guidance of the Key body for controlling the actuating tappet is achieved with extremely little effort not only in the manufacture of the Te le but also in their assembly.
  • Such a task is to be solved in watch cases with push buttons of the type mentioned above in that at least two slide guides are provided for guiding the key body in the housing wall, at least one of which directly guides the key body in the direction of movement of the associated actuating plunger, while the other, which is arranged inclined at an angle to the said guide, controls its alignment and securing of position during its movement via elements rigidly connected to the key body.
  • the guide which directly guides the key body should have straight guide tracks which run in or parallel to the direction of movement of the actuating plunger to be controlled.
  • two keyways are sufficient here, which, viewed in the direction of guidance of the second guide, lie at a distance from one another corresponding to the dimensions of the key body.
  • the second guide should preferably also be straight.
  • this second guide extends as far as the first one. You can then rigidly connect or integrally form an attachment to the key body to align it and secure its position, the free end of which is guided in the second guide with as little play as possible.
  • the width of this approach i.e. its dimensions in the direction of the housing depth or thickness should correspond at least at its free end to the width of the guide or the housing width.
  • the material thickness of the approach i.e. its dimensions in the radial direction relative to the housing are, over its entire length, less than the distance between the guideways of the guide, while at the end it corresponds to this distance.
  • the key stroke should be limited so that the outer surface of the key body is flush with the housing circumference in the rest position, which can be achieved in a simple manner by means of a stop which is connected, for example, to the key body and into an associated recess of the key body If the housing engages or vice versa, a stop on the housing can engage in a recess or opening provided in the key body.
  • Fig. 1 is a view of the housing with Tei l broken away parts and Figure 2 is a section on the line 2-2 of Figure 1.
  • the part shown in FIG. 1 as an example of a wristwatch case 11 shows the area between the crown 12 and the connection 112 for the bracelet 18.
  • the watch case has, as can be seen in FIG. 2, the shape of a circular disk, the central opening of the movement records. This center opening is closed on both sides by the bezel 13 with the watch glass 131 on the one hand and the bottom or cover 14 on the other.
  • a cutout 113 is provided, in which an essentially rectangular key body 15 is guided.
  • the guideways 114, 115 which are formed by the end walls of the recess 113, serve primarily for guiding the key body.
  • These guide tracks are arranged parallel to the axis of an actuating plunger 16, which is mounted in the housing wall 111 so as to be displaceable against the pressure of a spring 1 ⁇ .1 and serves to control elements of the clockwork, not shown.
  • the cutout 113 with the guide tracks 114 and 115 is followed by a cutout 116 with the guide tracks 117 and 118, the guide direction of which runs at an angle to the guide tracks 114, 115.
  • a neck 151 protrudes of the key body 15, corresponds to the material thickness at its free, protruding end 152 "to the distance between the feet approximately tracks 117 and 118 have each other.
  • this approach 151 is approximately tracks between the two Füh ⁇ 117, 118 guided and ensures practically no play, especially if its width corresponds to the width of the guideways and thus the depth of the housing, to ensure that the key body, when it is moved in the recess 113, cannot tilt and clamp between the bezel 13 and the base 14.
  • the material thickness of this approach 151 decreases towards the key body 15.
  • the key body 15 can be moved from the position shown in full lines in FIG. 1 to the position indicated by the dashed lines, with its front faces 153 and 154 being on the .
  • the associated guideways 114, 115 of the recess 113 are guided and the key body 15 is thus displaced essentially in the direction of the axis of the actuation push 16.
  • the movement of the key body 15 in the recess 113 is limited on the one hand by its abutment on the bottom 119 and on the other hand by a projection 155 of the key body 15 which can be seen in FIG. 2 and which engages in a recess 132 made in the bezel 13.

Abstract

Dans un boîtier de montre, en particulier pour des montres-bracelets, avec un ou plusieurs boutons-poussoirs pour actionner des éléments commandables du mouvement, la présente invention prévoit, pour le guidage du corps de bouton dans la paroi du boîtier, au moins deux guides à glissement dont l'un au moins garantit directement le guidage du corps de bouton dans la direction de déplacement du coulisseau d'actionnement respectif, alors que l'autre, incliné selon un certain angle par rapport au premier guide, commande pendant son déplacement, grâce à des éléments fixés au corps de bouton, l'alignement et le positionnement de ce dernier.
