Definitions

  • the invention relates to a vacuum cleaner according to the preamble of claim 1.
  • a cover is pivotally hinged to a device housing.
  • a displaceably mounted release button on the device housing, which is to be operated by hand to unlock a hook connection.
  • the release button must be gripped in order to release the lock, with openings, indentations or the like having to be provided in the device housing or cover for the release button.
  • the invention has for its object to take a vacuum cleaner according to the preamble measures by which unbroken or cut out surface sections on the lid and housing are used with ease of handling in the area of the locking device.
  • a vacuum cleaner according to the invention with a heart switch mechanism, no need to be able to intervene directly with a moving part. Rather, it is sufficient to exert a compressive force on the cover itself in the area of the locking device in order to actuate the heart switching mechanism. Breakthroughs in the cover or in the device housing for mounting an adjustable force transmission element are therefore not necessary, so that the cover and adjacent housing walls are separated from one another only by the required separation gap. Opening the tip of the heart enables a decoupling from the switching pin provided on the other component, so that the cover stroke is not limited by the stroke of the heart switching curve.
  • the switching pin is preferably freely displaceable in order to be able to keep the frictional forces occurring in the heart switching curve small so that this locking device can move freely.
  • a catch web is assigned to the open ends of the heart curve, which run like a funnel to the ends of the switching curve path, so that the switching pin independently of its current position within its working stroke automatically closes the lid to the heart tip and into the Switching curve is introduced.
  • the switching pin can slide in a guide part, which is subsequently attached to the component in question.
  • the switching curve on the other hand, can be connected in one piece to the other component, which can be shaped without an undercut.
  • the switching curve is arranged on the cover and the switching pin on the device housing, because the cover is accessible radially outwards from its peripheral edge, so a form slide must simply be pulled radially away from the edge of the cover to remove the heart switching curve.
  • the cover can be assigned a spring that automatically pushes it into an open position.
  • the elasticity of the lid is used for the advance within the switching heart.
  • stops are provided in the device housing on the side of the locking device, on which the cover strikes before the locking device engages. The cover is then bent by pressure forces exerted on it to such an extent that the locking device comes into its detent position or is released from this detent position.
  • a receiving space 2 designed as a recess for accessories, molded for example for suction mouthpieces 3.
  • a cover 5 which is pivotably mounted about a pivot axis 4 and carries a heart-shaped switching curve 6 of a heart switching mechanism on its edge facing away from the pivot axis 4.
  • a switching pin 7, which is mounted transversely to the adjustment direction of the cover 5 and parallel to its pivot axis 4 and is displaceably mounted on the housing 1, is in functional engagement with the switching curve 6, the switching curve 6 and the switching pin 7 forming the locking mechanism for locking the cover 5 in its closed position as a cardiac switching mechanism .
  • the surface of the cover 5 passes continuously and only continuously through the gap 8 required for the mobility into the plane of the adjacent housing part 1.
  • a torsion spring 4 a which is supported on the one hand on the cover 5 and on the other hand on the housing part 1 and is biased so that when the locking device 6, 7 is released, the cover 5 is automatically moved into its open position.
  • the switching pin 7 is freely displaceable in a slot guide 9 of a guide part 9 a, the length of the slot guide being matched to the switching stroke of the switching pin 7 required transversely to the cover movement direction in the switching curve 6.
  • the heart-shaped switching curve 6 sits on a carrier tab 10 which is perpendicular to the plane of the cover 5 and projects into the receiving space 2.
  • the carrier tab 10 runs parallel to a boundary wall 11 of the receiving space 2, the pin 7 being perpendicular to the carrier tab 10 on this boundary wall 11.
  • the heart-shaped switching curve 6 is arranged on the side of the carrier tab 10 facing the boundary wall 11 and is open towards the boundary wall 11, so that the switching pin 7 can intervene unimpeded.
  • the heart-shaped switching curve 6 is so arranged that the tip of the heart points in the direction of the pivoting movement of the lid in the receiving space 2.
  • the apex of the switching curve 6 is open so that the switching pin can move out of the guide region of the switching curve 6 or into this guide region through the opening 12 formed thereby.
  • a catch web 13 or 14 is formed, which are inclined away from the opening 12 in the manner of an opening funnel.
  • the funnel opening is placed in such a way that the switching pin 7 previously led out of the switching curve 6, regardless of its position in the guide slot 9, is gripped by the respective catch web 13 or 14 and inserted into the heart-shaped switching curve 6 through the opening 12 at the top of the heart when the lid is closed becomes.
  • the catch webs 13, 14 can be omitted if, for example, it is ensured by frictional forces that the switching pin remains in its position determined by the opening 12 after leaving the switching curve 6. Then, however, a considerable effort is required to switch the switching pin 7 through the switching curve.
  • the switching curve 6 can have an inhibiting point 6 a, which causes the switching pin 7 to accelerate into its stop position when overpressed.
  • the switching pin 7 rests in the inner angle of a heart elbow 15, which is located above the opening 12 within the switching curve 6 in the direction of movement of the cover.
  • the switching pin accordingly assumes the position designated 7.1 in FIG. 1.
  • the heart angle 15 therefore lies on the switching pin 7 and holds the cover in the position according to FIG. 2, in which it can be flush with the adjacent surface of the housing part 1 without a transition step.
  • the cover 5 By manual pressure on the cover 5, one provided above the heart angle 15 Wedge-shaped curve section 16 of the switching curve 6 in contact with the switching pin 7.1, which is thereby deflected sideways to the right so that it reaches position 7.2 from the area of action of the cardiac angle 15.
  • the cover 5 is already set back by a small amount in FIG. 1, so that the switching pin 7 has already moved away from the curve section 16.
  • the switching curve 6 moves with the cover 5 in the opening direction away from the receiving space 2, so that the switch pin 7 is passed past the heart angle 15 to the opening 12 and migrates out of the opening 12 when the cover 5 is released again. Then the cover 5 can be swung open freely.
  • one of the catching webs 13 or 14 strikes the switching pin 7 limited in its switching stroke, which is led through the incline of the respective catching web to the opening 12 of the switching curve 6.
  • the switching pin then strikes the flank of the heart angle 15 lying above the opening 12 and directs it to the left toward the flank of the switching curve 6, which is opposite the flank interacting with the switching pin 7 when the cover is opened.
  • the switching pin 7 thus arrives in the position designated by 7.3 in FIG. 1 to the most curved curve path of the switching curve 6 to the left. This curved path then inclines in the opposite direction over the inclined leg of the heart angle 15, so that the switching pin 7 at its most depressed position is above this leg.
  • a flank 17 of the wedge-shaped curve section 16 directed towards the opening 12 or the heart angle 15 prevents an adjustment of the switching pin 7, and thus also the cover 5, so that when the cover 5 is released, the switching pin 7 strikes the leg of the heart angle 15 from above and at its inclination in the interior angle in position 7.1 returns. The closed starting position of the cover 5 is thus reached again.
  • an additional spring element is preferably provided which is effective during the swivel angle range in which the heart switching mechanism is to be actuated.
  • the inherent elasticity of the cover 5 can be exploited, with a stop 18 on the housing part 1 preferably being provided to the side of the heart switching mechanism 6, 7. The corresponding edge region of the cover 5 hits these stops before the locking device 6, 7 engages.
  • the cover 5 is therefore designed to be elastically bendable, so that the locking device 6, 7 can be pressed into its detent position or released therefrom by increased pressure on the cover 5.
  • the spring element can also be designed as a spring wire rod 19 which is supported in the region of its ends on the cover 5 on support webs 20 and strikes counter-pressure webs 21 which are provided adjacent to the switching pin 7 on the housing part 1. But it can also be provided in the cover opening direction against the force of a compression spring mounted support bolt which, for example, comes into engagement with the carrier tab 10 as soon as the locking device 6, 7 engages.
  • the additional spring element then serves to overcome the forces required for the movement of the switching pin 7 and does not otherwise contribute significantly to the acceleration of the cover during the opening movement. In particular, the locking force is increased by the additional spring element.
  • the training according to the invention enables a design improvement with a high impression, in which other than the lid, there are no other visible controls.
  • the lid opens after manual external pressure with the lowest possible spring force, but remains in the event of unintentional actuation z. B. locked by closing the dust chamber, formed as a closure cover for the dust bag chamber with this securely.
