Definitions

  • the invention relates to a standing umbrella for use as a parasol, garden umbrella, market umbrella, etc.
  • This umbrella has a central standpipe with an umbrella frame, and an umbrella cloth as a roof covering that spans the roof struts in the open state.
  • the construction has its limits, however, if it is to be used for particularly large umbrellas of this type with a stationary crown, or if the umbrella should be as easy to use as possible. With large umbrellas, the forces to operate are too great. But there are increasingly umbrellas with large ones Umbrella areas are required, and in general the umbrellas, whether large or small, should be easy to use, i.e. with little effort.
  • a standing umbrella with a standpipe and a umbrella rod made of roof struts, which are articulated on a stationary end crown, and further with support struts, which are articulated with their upper end to the roof struts to support them and with their lower end to an am Standpipe sliding rotor crown are hinged, characterized in that either a gas or steel tension spring is arranged between the end crown itself or the upper end region of the roof struts on the one hand, and the outer or upper region of the support struts on the other hand, which when opening and tensioning the Umbrella has a supporting effect, as well as braking when closing.
  • FIG 1 The umbrella with umbrella rod, but without an umbrella cloth from the
  • FIG. 1 The umbrella with umbrella rod, but without an umbrella cloth from the
  • Figure 3 A toggle mechanism for tensioning the umbrella cloth on the open screen, before tensioning
  • Figure 4 The toggle mechanism for tensioning the umbrella cloth after tensioning.
  • FIG 1 the screen is shown seen from the side, in the closed position of the umbrella rod.
  • the construction consists of a standpipe 1 with an upper, stationary umbrella crown 2, to which the roof or umbrella struts 3 are articulated.
  • a rotor crown 4, on which the support struts 5 are articulated and supported, is arranged on the standpipe 1 and can be moved up and down.
  • These support struts 5 are hinged to the other, upper end approximately in the middle of the roof struts 3.
  • the essential elements are now the tension springs 6, which are each arranged here between the upper stationary end crown 2 on the one hand and the upper region of the support struts 5.
  • the tension springs in the example shown are not attached to the stationary end crown 2 itself, although they could also be, but in the immediate vicinity of the end crown 2 on the underside of the roof struts.
  • the other end of the springs 6 is articulated in the outer region of the support struts on the upper side thereof. Exactly where the attachment point should be, you have to try it out depending on the size of the umbrella, the geometry of the frame and for a given spring characteristic.
  • the example shown is steel tension springs 6, the spring force of which is selected depending on the size of the screen and the screen linkage geometry. Throttle cable springs can also be used in the same way.
  • FIG. 2 the screen is shown in the open position.
  • the tension springs 6 are here significantly shortened compared to their length in the initial state according to FIG. 1 and the spring force may already be reduced.
  • the springs 6 would be pulled out again and become longer.
  • the springs 6 are thus in a state of minimal extension when the screen is open and open.
  • the rotor crown 4 can be latched onto the standpipe 1 in various positions.
  • the standpipe 1 in the example shown has a plurality of holes 8 arranged one above the other.
  • the pawl is provided on the rotor crown 4 and the pawl pin can optionally latch into one of these holes 8.
  • Closing the screen is also made easier by the built-in springs 6.
  • the rotor crown 4 In the case of umbrellas without these springs, there is the disadvantage that when the rotor crown 4 is released, the umbrella immediately closes. If the operator is not prepared for this and is unable to hold the rotor crown with the necessary force, he is enclosed by the folding umbrella under the umbrella frame and umbrella cloth, and he has to bend down to get back under the Construction to emerge. In any case, in conventional constructions without a spring, he has to move the rotor crown downwards with the necessary counterforce to release it, in order to close the screen in a controlled manner. But that requires strength and the operator has to bend down under the folding umbrella construction. With the springs 6, however, the closing of the screen is much easier.
  • a toggle lever mechanism can be used for the actual tensioning of the roof skin.
  • the rotor crown 4 runs upwards and in order to tension the roof covering or the umbrella cloth, this rotor crown 4 must be stretched a few centimeters further up.
  • a lever 15 is articulated on this rotor crown 4, which lever, viewed from the standpipe 1, is angled slightly outwards.
  • the rotor crown 4 is shown below the drawing as seen from above. At the end of the lever 15, this carries a grip ball 16.
  • a toggle lever 17 is articulated, which is spring-loaded by means of a spring 18, so that it is always held in the angled position shown.
  • this toggle lever 17 has a cam 19 which fits into a number of holes 8 which are provided in a vertical row on the standpipe 1. However, only one such hole 8 is shown in the drawing.
  • the lever 15 can simply be engaged and tensioned with its toggle lever 17 with a higher hole 20 on the standpipe 1.
  • the rotor crown 4 can have a separate pawl, not shown here, with which it clicks on a toothing on the standpipe 1 when pushed upward, so that a ratchet is formed, and the rotor crown 4 is thus secured in every tensioned position.
  • the latch is knocked out and the roof skin is relaxed by swinging out the knee lever.

Abstract

L'invention concerne un parasol comprenant un tube (1) et une tringlerie constituée de baleines (3) articulées sur une collerette d'extrémité fixe (2) et soutenues par des branches d'appui (5) qui sont articulées, par leur extrémité supérieure, sur les baleines (3) et, par leur extrémité inférieure, sur un coulant (4) pouvant coulisser sur le tube (1). Un ressort de traction en acier ou un ressort pneumatique (6) est placé respectivement entre la collerette d'extrémité (2) ou la zone terminale supérieure des baleines (3), à proximité de ladite collerette (2) d'une part, et la zone extérieure des branches d'appui (5) d'autre part. Ces ressorts de traction (6) assurent un soutien lors de l'ouverture du parasol et un freinage et un amortissement lors de la fermeture.
