The swiveling plates are by means of a locking device arranged on the support in a coplanar position ascertainable. The locking device has an elongated, rounded bolt, which is slidably guided in a guide sleeve. The guide pin is biased by a spring and strikes in the working position of the holder a stop at which on a first of the two pivotable plates is provided. The bolt can be released using an actuator so that the plates can be swiveled. The bolt moves in Direction of spring force from a retracted stop position in Spring force direction in a partially relaxed release position. As soon as one wing is partially pivoted, the bolt can move into the release position, in which is also the second wing released.

The actuator consists of a pedal that can be pivoted by means of a hinge is attached to the first plate. A leaf spring provided on the pedal serves to to create a preload between the first plate and the support. At the Depressing the pedal can deflect the bolt upwards, and that Leaf spring forces the first plate to pivot clockwise and thus a release of the first wing.

It is an object of the invention to provide a holder for mop covers, which is simple and inexpensive to manufacture. Another goal is to get one For the sake of providing, with which a mop cover can be quickly opened can. The mop cover should not be held in your hands when opening Need to become. Another goal is to provide a holder which allows you to wring out a mop cover without closing it from the holder to take.

The rollers 31 have the purpose of sliding the Ends 27, 29 via the mop cover 13 when the wings 19, 20 are inserted into the to facilitate opposing pockets 51, 52 of a mop cover. Following the rolling means 31 are a recess 35 in the wings 19, 20 provided, in which a belt reel 37 is arranged. Between belt reel 37 and The edges of the recess 35 are slots 38, 38 'through which one Straps 33 of a mop cover can be looped. The straps 33 will preferably looped through the slots 38, 38 'such that the straps 33 are underneath the rolling means 31 extends. The rollers 31 and the belt roller 33 are each on one Axle bolt mounted, which from the bottom into a on the wing 19.20 trained axle bearing can be snapped.

On the top of the wings 19, 20 there are preferably two as pins 41 trained locking means provided. The pins 41 act with the bolt 43 (Fig. 8 and 9) of the base plate 15 together. The pins 41 have undercuts 46, which can snap into the corresponding recesses 45 in the bolt 43. The recesses 45 can, as shown in FIG. 8, an undercut Have 48. Each pin 41 is symmetrical, so that it from both sides can work here equally with the bolt 43. thanks to the symmetrical design of the peg can be the same wing 19.20 on each side of the holding part 15 are used.

On the base plate 15 are webs 62 with round holes 64 for receiving Axle pin 61.63 provided. In the assembled holder 11, the Axle bolts 61, 63 through the round holes 40 of the wings 19, 20 serving as axle bearings. A space 65 is present between the opposite webs 62, in FIG which the middle part 66 of the preferably one-piece bolt 43 extend can.

In the area of the actuating pin 55, a link surface 49 is formed in the bolt 43, which can cooperate with the lower end of the actuating pin 55. The Actuating pin 55 has a head 54 at the upper end and one at the other end Sliding surface 57. The sliding surface 57 interacts with the link surface 49 in such a way that that when pushing the actuating pin 55 of the bolt 43 against the Spring force of the spring means 47 is moved into the release position. In the Undercuts 46 come out of the engagement of the Recesses 45 so that the wings 19, 20 can be pivoted. The actuating pin 55 can be biased with a spring 56, as shown in FIG. in principle the spring means 47 acting on the bolt 43 can be dimensioned such that this both the bolt 43 and the actuating pin 55 in the starting position able to push back, so that an additional spring 56 is dispensed with can.

Analogous to the actuating pin 55, there is also a sliding surface 58 on the pin 41 educated. The sliding surface 58 can with the edges of the recesses 45 such interact that when the wings 19, 20 e.g. through a vertical Force acting on the holder from above, the bolt 43 in the direction of the arrow 60 is pushed back. Once the undercuts 46 of the pin 45 are engaged get with the paragraphs 48, the spring biased by the spring means 47 snaps Bolt 43 automatically in the locking position.

So that the wings 19, 20 automatically when the actuating lever 24 is actuated jump into the folded position, are between the base plate 15, respectively. bolt 43 and the wings 19, 20 acting spring means 59 are provided. The spring means 59 are preferably as an elastic pin protruding from the surface of the bolt 43 or tongues 59 formed, which in the tensioned position of the holder Preload between the base plate 15 and the wings 19, 20. As soon as the bolt 43 reaches the release position, the wings 19, 20 by the acting Spring force partially pivoted. The spring means 59 are integral with the bolt 43 trained. Counter-forms to the spring means can also be provided in the wings 19, 20 59 be formed, which cause the spring means only at its extreme Press the end onto the top of the wings 19, 20.

1 to 3 and 5 to 12 are the Pivot axes 21, 23 at a distance from one another and also at a distance from the underside arranged the base plate. The latter feature allows the wings to be flat train. In the tensioned position, the wings thus extend in one common plane on both sides of the swivel axes.

The style attachment device is midway between the two Swivel axes 21, 23 are provided. By trained as stops 26 proximal ends of the wings 19, 20 remain in place when the holder 11 is raised an angle to the base plate 15.

The exemplary embodiment according to FIG. 4 differs from the others Embodiments in that the wings 19, 20 around a common Pivot axis 22 are pivotable. They thus form in the folded position isosceles triangle.

The holder 11 according to the invention can be used particularly advantageously in Connection with a mop cover 13, which is a band or a on the top Has straps 33 for connection to the holder 11. The mop cover 13 will Use attached to the holder 11 by the preferably two-part straps 33 through the spaces 38, 38 'are looped and the ends of the two belt parts e.g. be connected by means of a Velcro fastener.
