Summary of the invention

In view of above-mentioned prior art, the technical problem to be solved in the present invention is: make up the attachment device of the type of being discussed in a kind of improved mode, so that it can be implemented in the configuration that has superiority in the stop position.

This problem at first is resolved by the theme of claim 1, wherein proposes, and brush can move to retrieving position vertically from bonding station, and brush enters the motion of retrieving position and motion that guide shank enters stop position is coupled.In this case, bonding station is the brush of attachment device and the contacted position, floor that will be cleared up, and at retrieving position, brush is lifted away from the floor that will clear up.Structure according to the present invention provides a kind of attachment device, is particularly to brush, preferably is arranged on the stop position.Described brush is lifted on stop position.Thereby brush no longer contacts with the floor, and when moving whole attachment device when guide shank is positioned at stop position, because the frictional resistance that produced by the brush that contact with the floor does not take place in this case, so prove that the present invention also is favourable in this respect.

Be explained as follows with reference to the theme of claim 1 theme, but these claims also have importance on its independent design other claims.For example, for form described coupling with mechanical couplings, confirmed that the present invention has special advantage.This structure provides simple in structure and solution cost-effective.In the process of the joint motions of verting, guide shank enters stop position and the displacement carried out mechanically acts on the brush, and its mode is that described brush moves to retrieving position vertically.The motion of verting that guide shank enters stop position changes the vertical motion of brush subsequently into.Mechanical couplings further so forms: usual the vert motion of guide shank on operating position, for the vertical displacement of brush without any influence.With respect to the floor that will be cleared up, brush can remain on contact position, can not influenced by the guide shank that will vert on operating position.Any vertical freely-movable of brush can not be affected yet, and the carpet pile of this motion permission brush and differing heights etc. is complementary.Brush also is

manner), be installed to extend on the armed lever and in brush side and be fixed on the articulated arm in the joint side.Thereby the displacement of verting that guide shank enters stop position is passed to adjutage by hinged cable linkage, so that brush is raised to retrieving position vertically.In this case, the cable linkage so is provided with and forms: only just produce tension force when guide shank is displaced to stop position, and do not produce tension force at the usual operating position of guide shank.Can remain on the free-moving ability of the vertical direction of brush on the operating position.Also propose, extend armed lever and/or articulated arm and form with wheel or roller part, and the cable linkage, on its a part of length, follow the periphery of wheel or roller part respectively.In this case, the cable linkage forms with band, cable or plastic rope.The cable linkage is wrapped in the top of extending the armed lever roller part.From this, the cable linkage strides across the adjutage rotation and the space between the joints axes of verting, and is installed to the wheel of articulated arm or the downside of roller part at the other end.Can also between articulated arm and extension armed lever arrangement for deflecting be set, for example be the form of roller.At the operating position in joint that verts, the cable linkage is at articulated arm and extend not tensioning between the armed lever.When guide shank is switched to stop position, the tensioning of cable linkage, and this linkage is moved brush to retrieving position by adjutage.As an alternative, described coupling can also directly form by extending armed lever and connecting rod.In this case, these bars are with formation such as rigid plate, and this rigid plate is roughly radially outstanding, and is connected with the part of rotatable fixed form with the adjutage and the joint of verting, and this part in this joint of verting is held guide shank.Extend armed lever and can pass through the articulated arm start thus, this articulated arm forms drive member, just to carry the mode of action (carry-along action).On operating position, articulated arm and the distance of extending between the armed lever make, can guarantee the required freely-movable ability that freely moves pivotally of following adjutage.At last, brush is proposed by being arranged on the motor-driven in the attachment device.Thus, because driven always brush breaks away from the floor that will be cleared up on the stop position of apparatus, the result can prevent the floor damage, so structure according to the present invention has superiority.This device also can reduce the wearing and tearing of brush bristles.The brush motor still remains in operation when brush is in the lifting position, and this will indicate this apparatus of user to remain and open.
