Definitions

  • the invention relates to a parachute according to the preamble of claim 1.
  • the object of the invention is to design a parachute of the type mentioned at the beginning in such a way that it has an electric motor drive in a manner known per se and can nevertheless be actuated by hand at any time without any manipulations.
  • the clutch can be a permanent clutch that connects the motor drive to the manual drive.
  • the switched-off motor must have practically no resistance to the manual drive, it must run idle and must not have any dynamic effect.
  • a clutch according to claim 2 is more advantageous.
  • the clutch for the motor drive can be an electromagnetic clutch, which closes automatically when the motor drive is actuated and opens again when the motor drive is switched off, in that the electromagnetic clutch with the drive circuit of the Motor drive is connected.
  • An embodiment according to claim 4 is particularly advantageous, wherein the clutch engages independently of the drive circuit. Other known automatic clutches are also possible.
  • the brake can be a switched brake that can be actuated, for example, by hand or by means of the motor circuit. It is more advantageous to design the brake according to claim 5 and to further develop it according to claim 6.
  • a self-locking gear can be formed, for example, by a drive spindle with a self-locking thread or by a self-locking worm gear, ' which enables actuation on the drive side, but cannot be actuated on the roof side.
  • the drive spindle according to claim 9 expediently has a non-self-locking, that is to say steeper thread, which means that the parachute can be opened and closed with a smaller number of spindle revolutions.
  • Claim 10 describes a particularly space-saving and practical design of the parachute.
  • Figure 1 shows a parachute in vertical section
  • Figure 2 shows a further coupling of a
  • FIG. 3 shows a one-way brake in vertical section; and Figure 4 shows the one-way brake of Figure 3 in
  • the standing umbrella shown in FIG. 1 has an umbrella stick 2 which contains a lower fixed stick part 4 and an upper telescopic stick part 6.
  • a crown 8 is arranged, on which 10 roof rods 12 are articulated via joints.
  • the latter are supported by support rods 14 on a sleeve 16 which is displaceably mounted on the lower floor part 4.
  • the support rods 14 are connected to the sleeve 16 via joints 18 on the roof rods 12 and via joints 20.
  • the latter is connected to the upper floor part 4 via a support cable 22, which is guided over a deflection roller 24 at the upper end of the lower floor part 6.
  • the above-mentioned parts form the mechanism for opening and closing the canopy.
  • the design of the standing umbrella with the roof frame is made in such a way that the center of gravity of the roof frame remains essentially at the same height when opening and closing the standing umbrella, as a result of which the force required for opening and closing is particularly small.
  • a drive 26 is arranged on the upper stick part 6, which consists of a threaded nut 28 which is fastened in the stick part 6 and into which a drive spindle 30 is screwed.
  • This drive spindle 30 is connected at the lower end to an automatic one-way brake 32, to which a shaft 34 is connected at the bottom and is connected to a motor drive 38 via a clutch 36.
  • the one-way brake 32 is fastened to the inner wall of the lower floor part 4 via a bracket 40.
  • the motor drive 38 and the clutch 36 are also combined to form a unit which is fastened to the inner wall of the lower floor part 4 via a further bracket 42.
  • a hand drive 44 is also connected to the shaft 34 and is made of a bevel gear pair 46, 48 is formed, a hand crank 50 being insertable into the outer bevel gear 48.
  • the drive of the stationary screen is designed such that either the motor drive 38 or the manual drive 44 can be connected to the drive spindle 30.
  • the clutch 36 which is for example a centrifugal clutch or an electromagnetic clutch connected to the drive circuit of the motor drive, is switched off when the motor drive 38 is at a standstill, so that the shaft 34 can be actuated independently of the motor drive 38, for example by means of the manual drive 44.
  • the one-way brake 32 is designed such that a torque can be delivered to the drive spindle 30 by the motor drive 38 or by the manual drive 44, but no torque is delivered to the shaft 34 by the drive spindle 30.
  • the opening and / or closing movement of the stationary screen is expediently limited by limit switches, not shown.
  • the position of the limit switches and / or associated actuating cams can preferably be adjusted in order to be able to adjust the degree of opening and / or closing of the standing screen.
  • FIG. 2 shows a rigid coupling of the motor output 38 to the manual drive 44.
  • the coupling 52 is formed by a sleeve 54, which sits at one end on a shaft 56 of the motor drive 38 and is connected to it by a pin 58.
  • the sleeve 54 is arranged on the shaft 34 of the manual drive 44 and secured by means of set screws 60.
  • the currentless motor drive provides practically no resistance to the manual drive. set, ie it must run idle and must not have a dynamic effect.
  • FIGS. 3 and 4 show a preferred embodiment of the one-way brake 32 of the parachute of FIG. 1.
  • a cylindrical shaft section 62 is arranged on the shaft 34 coming from the manual drive 44 and is provided with a longitudinal groove 64 which is V-shaped in cross section.
  • a helical spring 66 is arranged on the cylindrical shaft section 62, the ends 68, 70 of which engage in the V-shaped groove.
  • Arranged around the helical spring 66 is a stationary cylinder 72, on the inner wall 74 of which the helical spring is supported.

Abstract

Le mécanisme pour l'ouverture et la fermeture d'une couverture de parasol disposée sur un mât (2) présente une commande manuelle (44) et une commande à moteur (38). La commande à moteur (38) est couplée par un dispositif d'embrayage automatique (36) à un arbre (34) relié au mécanisme. En outre, il y a entre la commande à moteur (38) et la commande manuelle (44) un frein unidirectionnel (32) qui est inactif du côté de la commande et actif du côté de la couverture.
