Definitions

  • the invention relates to a connecting device for two mutually movable components according to the preamble of the main claim.
  • the known arrangement has the disadvantage that only small angles are possible and that a "gaping gap" occurs immediately when deflected, so that injuries to the operating personnel can occur in the case of components which must be easily accessible.
  • the known device furthermore has a constant lever arm between the support point and the force application point of the drawbar and also only a small spring tensioning path, so that no high "restoring forces" can be achieved.
  • the invention has for its object to improve the generic device in such a way that a very stable holder can be reached in the idle state and a high restoring force is achieved in the angled state.
  • the procedure is such that the two components, namely the work part and the support part, have geometrically adapted common contact surfaces or contact shells in such a way that the static elements of the wedge (clamping, stable fit and high force absorption) are included on the one hand
  • the dynamic elements of the ball joint that becomes effective after the initial force is absorbed, whereby the dynamic elements of the ball joint achieve elastic resilience and reset with the help of a spring in a positively guided, safe movement without "gaping" the connecting parts.
  • the new three-dimensional or spatial dimension provision i.e. in the x, y and z axes, opens up new areas of application.
  • the device defined according to the invention brings about a defined seat which is stable in three directions, which, due to its partial wedge-like shape of the two components, has the same effect as a clamped-in carrier and, during the movement, a defined, controlled movement sequence over a large angle of inclination with reliable guidance of the inner shell in the outer shell while avoiding the dangerous gaping mouth of this device.
  • connection device that demands such as increasing passive safety in road and motor traffic can be realized economically, e.g. Overload protection for small, medium and large signs and three-dimensional automatic repositioning in stable, yet lightweight constructions.
  • the high restoring torque is able to set up even heavy and especially long components after a 90 ° deflection.
  • connection according to the invention has an essential new technical application due to the reset effect in combination with electrical or electronic contact deliveries, which on the one hand result in one or more reports of events, e.g. Dangers that can be used and that can even be used to control processes, e.g. if the object, such as an awning or the like, is to be wholly or partially controlled out of the danger. For example, it is possible to partially or partially retract awnings in the event of excessive wind loads.
  • events e.g. Dangers that can be used and that can even be used to control processes, e.g. if the object, such as an awning or the like, is to be wholly or partially controlled out of the danger.
  • a connection device for two components A and B is shown schematically in FIG. 1, component A being designated as support part 1 and component B as working part 2 in the following explanation.
  • the carrier part 1 is connected to the working part 2 via a pull rod 3, which rests on the inside of the carrier part 1 by means of a ball end 4, slots 5 being worked out in the conical tip of the carrier part 1, which angled the pull rod from that in FIG. 1 shown position, for example in the position shown in Fig. 2, allow.
  • a helical spring 6 one end of which rests on a corresponding ring bearing surface 7 of the working part 2, the other end is supported on the underside of an abutment disk 8 which is carried by the pull rod 3.
  • the lower end of the working part 2 overlaps a bell-shaped and truncated cone-shaped component of the carrier part 1.
  • the carrier part 1 has a circumferential abutment 9, against which the lower end of the hood 10 can be supported when the working part 2 is tilted.
  • the hood 10 lies tightly against the rotationally symmetrical truncated cone 11 of the carrier part 1.
  • the working part 2 When force is exerted on the working part 2, for example in the direction of the arrow K in FIG. 1, the working part 2 can evade by the lower end of the hood 10 being supported on the abutment of the carrier part 1, the spring 6 being tensioned at the same time and the Drawbar 3, as shown in Fig. 2, migrates from its position shown in Fig. 1 in the position shown in Fig. 2, the angle of inclination of the working part 2 is dependent on the force acting on the working part 2 K.
  • the extreme position shown in FIG. 2 for this embodiment only serves as a comparison for explaining the different movement sequence in FIG. 5, the embodiment of which - as described further below - is suitable for large angles with firm guidance.
  • the limitation of the mode of action to the permissible angling of the embodiment in FIGS. 1 and 2 is achieved by limiting the spring travel.
  • the support of the working part 2 in the area of the abutment 9 on the support part 1 is such that when the working part 2 is tilted relative to the fixedly arranged support part 1, the lever arm of the abutment 9 for the working part 2 from the point of application of the spring on the support part , ie that is, the contact of the ball end 4 on the apex of the truncated cone 11 in the relevant area becomes even larger when deflected. This ensures that the required restoring torque is always available when the working part 2 is deflected relative to the carrier part 1.
  • Fig. 3 shows a modified embodiment of the invention with a carrier part 1 a and a working part 2a, the two parts now trough into one another and thus the linear abutment 9a is formed in the region of the upper edge of the trough of the carrier part 1 a.
  • the spring is a spiral spring within the hood shape.
  • the tie rod 3a is held securely on the support part 1 a, but there is no fixed guidance of the internal component on the tie rod.
  • 3 and 4 also illustrate that it is completely independent of the effect of the device according to the invention whether the spring 6 is inside the working part 2 or inside the carrier part 1 or in other words inside or outside the hood shape.
  • FIG. 4 is intended to show the pyramid-like design analogous to the conical or rotational shape corresponding to FIG. 1.
  • the named effects of the connecting device are also given in this embodiment.
  • Fig. 5 shows an important embodiment that allows a very large (about 90 degrees) angle of inclination with firm guidance of the inner component through the shell contour of the outer component in the motion sequence while avoiding the gaping gap that is dangerous for many constructions.
  • FIG. 6 shows the design as a profile section, analogous to the conical design of FIG. 1 with a flat contact and analogous to the embodiment of FIG. 3 as a profile section design.
  • the actual work part is used in this example as a label holder.
  • the effects named for the invention are also achieved here, ie this form can not only convert the tilting forces into torques, but can also absorb torsional forces and restore spatial (XYZ) reorientation after the interference force has ended.
