Definitions

the invention relates to a vacuum cleaner mouthpiece which, with respect to the working direction, has, at least on its front side, a pivotable work bar which delimits the suction channel of the mouthpiece.
Such a vacuum cleaner mouthpiece is known from DE-GM 74 31 298.
the work bar consists of an elastic strip in the lower part. This enables perfect suction to a wall edge.
the elastic strip is pivoted in accordance with the respective direction of movement and assumes a curved shape.
the contact edge essentially slides over the carpet pile and does not penetrate it deep enough.
the invention has for its object to provide a vacuum cleaner mouthpiece in which the support edge of a pivotably arranged work bar comes into effect as optimally as possible despite the deflection thereof.
the adjacent to the surface to be cleaned support edge of the work bar opposite the suction channel is designed as an outwardly facing, projecting tip, the angle between the tangent to the center line of the tip and the center line of the vertical part of the working edge is an obtuse angle.
the work bar is pivoted backwards due to the frictional resistance with the carpet pile, so that the tip of the working edge comes into engagement with the carpet pile.
the tip is able to penetrate the carpet pile and open it accordingly for better access to the suction air.
a steep engagement of the tip necessary for the wide opening of the carpet pile is achieved in that the angle between the tangent to the center line of the tip and the center line of the vertical part of the work bar is 110 to 160 degrees.
a pivotable work bar is arranged on both sides of the suction channel and the contact edge of each work bar is designed as an outwardly projecting, protruding tip relative to the suction channel.
a work bar with the tip of its working edge comes into effect both in the forward and backward movement of the mouthpiece.
a rounded course of the contact edge towards the tip end contributes to reducing the sliding resistance, since the rear work bar in the respective direction of movement lies on the carpet pile with the rounded part of its working edge and thus glides over the carpet pile without any significant frictional resistance.
FIG. 1 shows a suction mouthpiece in the rest position and FIG. 2 shows a suction mouthpiece when pushed forward.
a suction mouthpiece With 1 the housing of a suction mouthpiece is referred to, to which a suction pipe 2 which can be connected to a vacuum cleaner is connected.
a work bar 5 or 6 is pivotally attached by means of an elastic hinge band 7.
the contact edge 8 of each work bar 5 or 6 is designed as a tip 10 which points outward relative to the suction channel 9.
the tip 10 of the work strips 5 and 6 protrudes from the plane of the vertical part of the work strips 5 and 6.
the work strips 5 and 6 can be formed as continuous strips and fastened to the mouthpiece housing 1 by means of an elastic connecting member. But there is also the possibility of dividing the work strips 5 and 6 into individual elastic tongues arranged side by side. Such tongues can be rigidly attached to the mouthpiece housing. The tongues are deflected due to their inherent elasticity. When the suction mouthpiece is moved, only individual tongues are bent in each case in accordance with the resistance forces which act in different ways across the width of the suction mouthpiece, and these springs spring back into their starting position when the respective resistance force decreases. Through this movement of the tongues, the carpet pile is continuously massaged and opened, so that the suction air can penetrate deeply into the carpet pile and carry along the dirt stored there. In addition, since not all tongues are deflected at the same time, the pushing force is significantly reduced.
the tangent 14 at the end of the tip 10 is applied to the dashed center line 13 of the tip 10.
the tangent 14 forms an obtuse angle ⁇ with the center line 15 of the vertical part of the work bar 5. It has proven to be particularly favorable that the angle ⁇ is in the range between 110 to 160 °.
