Definitions
- the invention relates to a spring arrangement for the closure flap of a filter bag in a vacuum cleaner.
- the flap is used to close the entrance to the filter bag.
- flaps that can only be closed when the vacuum cleaner is opened to change the filter bags. This is done either manually by moving a locking tab or automatically by a spring.
- BESTATIGUNGSKOPIE Flap opening in use the z. B. open the flap as a membrane with a lever.
- Curved leaf springs are often used, which have a degression when they are deflected to a certain extent.
- the feathers snap through. (This effect is used in the crack frog).
- the flap is opened further, the spring force also increases continuously with these springs.
- each further opening increases the bending load on the spring.
- the object of the invention is to provide a spring arrangement which allows a wide opening without a large increase in force, so that the spring is not heavily loaded.
- the contour of the spring element should be relatively flat so that it can be easily bent around the hinge of the closure flap.
- a very flat and also a degressive characteristic curve can be achieved, although a high locking force can still be generated at the beginning by the effective lever arm. If the fulcrum If the flap is selected appropriately and there is also a recess in the hinge, a characteristic curve is also possible that goes into the negative range. This means that the closing force is less than 0 and the closing flap remains open. To do this, the neutral
- a recess is made in the closure flap, into which the spring element is completely immersed in the open state, so that no edge or elevation which could hinder the flow protrude beyond the closure flap.
- a seal can be attached to the spring element, which acts between the closure flap and the filter bag. In all cases, it is advisable to choose a material for the spring element that makes it difficult or impossible for dirt to adhere. In the latter case in particular, it is advantageous if the spring element completely covers the closure flap.
- FIG. 1 shows a spring element 10 according to the invention, installed in a filter bag 12.
- the flat spring element 10 is fastened with its one end to the filter bag 12 and with its other end to a closure cap 14.
- An opening angle of the closure cap 14 of approximately 45 ° is shown.
- FIG. 2 shows the spring element 10 installed in the filter bag 12 in the state in which the closure flap 14 is closed.
- FIG. 8 shows the prior art in which a leaf spring 16 is used.
- the leaf spring 16 has a crown (curvature in cross section) so that the spring force drops again after a certain opening angle.
- An opening angle of the closure flap 14 of approximately 45 ° is shown here.
- the leaf spring 16 is effective as a spiral spring. It is advantageous that the flow is not hindered by the leaf spring 16 in this embodiment, since the air flows past on the other side of the closure flap 14.
- the disadvantage is the heavy load on the leaf spring 16 when the closure flap 14 is opened wide.
- Fig. 3 shows a schematic representation of the spring element 10 according to the invention, installed in the filter bag 12, wherein the closure flap 14 assumes the closed position. It can be seen that an arrangement of at least one of the fastening points of the tension spring 10, which is higher than the inner surface of the filter bag 12 and the closed flap 14 and its axis of rotation, and the spring force acts as a torque with a lever arm with respect to the hinge axis, which results in a secure Closing the flap 14 leads.
- FIG. 4 shows the spring element according to FIG. 3 with a small opening angle of the closure flap 14. At this small opening angle, the spring element 10 does not yet rest on the hinge, but extends in the area of the hinge, irrespective of a possible attachment to the fastener. fixing points and outside the area of the hinge, freely over it.
- FIG. 5 shows the spring element 10 according to FIGS. 3 and 4 with an opening angle of the closure flap 14 of approximately 70 °. It can be seen that with this large opening angle the spring element 10 bends around the hinge of the closure flap 14. A further opening of the closure flap 14 only leads to a very slight increase in the torque and the spring load.
- FIG. 6 shows a version modified compared to FIG. 5 with an opening angle of the closure flap 14 of likewise approximately 70 °.
- this version there is a recess in the hinge and in the closure flap 14, into which the spring element 10 can dip. Depending on the size of this recess, there is a torque in the opening direction from a certain opening angle, so that the closure flap 14 remains open.
- the neutral fiber of the spring element 10 lies below the axis of rotation of the hinge of the closure flap 14.
- A denotes a curve which drops to a low level.
- Another curve B drops to 0 and then rises again slightly. The point where the curves drop to 0 or to the minimum can be determined simply by the geometry of the spring element attachment and the choice of spring.
