No. 758,302 Claims priority, application Switzerland, Sept. 15, 1967 13,048/67 Int. Cl. A471 13/46, 17/00; B25g 3/38 US.. Cl. 15-147 5 Claims ABSTRACT OF THE DISCLOSURE In a handle for a hand mop for cleaning household crockery, a sponge is carried by a sponge-fastening member which can pivot relative to a grip portion of the handle. A V-shaped leaf spring maintains the fastening member in either of its two limit positions as desired.

The present invention relates to a handle for a hand mop for cleaning household crockery, having a fastening member for carrying a cleaning member such as a sponge or the like, the fastening member being pivotally mounted at one end of the handle.

According to one aspect, the invention is concerned with the problem of developing a locking device which permits a large angle of pivotal movement between the handle and the fastening member and is extremely simple and reliable in operation.

According to the invention there is provided a handle for a hand mop for cleaning household crockery, the said handle comprising:

(a) a grip portion by which the user can hold the handle,

(b) a fastening member pivotally connected to the said grip portion,

(c) a pivot pin effecting the said pivotal connection between the said grip portion and the said fastening member,

(d) mean-s for mounting a sponge or like cleaning member on the said fastening member,

(e) V-shaped cam means including two stop faces at an acute angle to each other constituting a portion of the said fastening member,

(f) a recess in that end region of the said grip portion that is adjacent to the said fastening member, and

(g) a leaf spring partly accommodated in the said recess and engaging at least one of the said stop faces to maintain the said fastening member at a desired pivotal orientation relative to the said grip portion.

The said grip portion may be bifurcated into two fork arms at its end adjacent to the said fastening member and may include lateral walls joining the said fork arms, the said lateral walls serving in operation as limit stops engaging the said stop faces to limit pivotal movement between the said grip portion and the said fastening member.

The said leaf spring is preferably -substantially V-shaped` and has the end of each limb of the V bent outwardly. The invention also provides a handle for a hand mop for cleaning household crockery comprising:

fice

same, whereby the blade or spade provides support over an extended area for the cleaning member in use.

With a fastening member of this type, a large pressure area always bears against the particular sponge pad being used, whereby the effective part of the working face is considerably enlarged. In addition, by holding the device itself at an angle, a high pressure can be exerted on the corner regions of the sponge pads, which is particularly useful when cleaning the inside corners of pans.

As is readily apparent, these advantages of the larger pressure face are found independently of whether the fastening member is rigid or -tixed to the handle by means of a hinge and independently of the construction of the hinge.

With previously known mops for cleaning household Crockery, the sponge fastening rings have been constructed with a frame cross section which is round or elongated in the axial direction of the ring. Such rings exert a satisfactory Iworking pressure only on a small central region of the sponge 'working faces while the outer regions and particularly the corner regions of the sponge are not supported. The efficiency of such devices is low, the rate of wear of the central regions of the working faces very high and the working life of such a sponge extremely short.

Illu-strative and nonlimitative embodiments of the invention are illustrated in the accompanying drawings, in which:

FIG. 1 shows a side view of a sponge mop provided with the hinge according to the invention, with the sponge in an inclined working position,

FIG. 2 shows the hinge region of FIG. 1 with a longitudinal section through the bifurcation taken in a plane parallel to the plane of pivotal movement, with the fastening member in its central position.

FIG. 3 shows a similar view as to that of FIG. 2, but with the fastening member in an inclined working position,

FIG. 4 shows the hinge region corresponding to FIGS. 2 and 3, with a longitudinal cross section of the bifurcation taken perpendicularly to the plane of pivotal movement and with the fastening member in its central position,

FIG. 5 shows a side view of a further embodiment of a mop with an annular sponge fastening member in an inclined working position, and

FIG. 6 shows a plan view of the sponge fastening member shown in FIG. 5.

The mop according to FIGS. 1 to 4 essentially comprises a handle 1 pivoted to a fastening member 2. The latter carries a cleaning member 3 which in this example of the invention is in the form of a sponge. The cleaning member 3 is provided with two working faces 3a, 3b of different abra-sive characteristics. The lower end region of the stick 1 is in the form of a fork and has the two fork arms 1a (FIG. 4). Above the pivot pin 4 the two fork arms 1a are laterally joined to form a cap, by the integral walls 1b. A central arm 2a is pivotally mounted between the two fork arms 1a and is moulded to the fastening member 2. The arm 2a is inverted-V-shaped in its upper end region and thereby has two stop faces 2b 'which are set at angles corresponding to the desired limiting angles of pivotal movement. The faces 2b cooperate with the 'walls 1b of the fork which act as stops. A substantially V-shaped leaf spring 5 serves to resist and prevent undesired pivoting of the fastening member 2. The leaf -spring 5 is loosely mounted with its lower end region Sa in a recess 1c disposed centrally in the base of the fork. With the fastening member 2 in the central position the two limbs 5b of the spring lie in contact with the inverted- V-shaped end region of the central arm 2a. During pivotal movement of the fastening member 2 both ends of the limbs of the spring 5 remain in sliding Contact with the corresponding faces 2b of the central arm 2a. The whole device is so arranged that the highest point of the cam means 2c formed by the two stop faces 2b, when the fastening member 2 is in its inclined working position, lies radially outside (with reference to the pivot axis) the highest (i.e. furthest from the axis) points of the bent portions 5c of the ends of the limbs of the spring. As particularly apparent from FIG. 3, the spring 5 has a slight clearance for movement in the recess 1c in the plane of pivotal movement and can therefore take up a position at a slight angle to the longitudinal axis of the handle 1, due to the two limbs 5b lying against one of the faces 2b of the central arm 2a.

An alternative embodiment of the invention is shown in FIGS. 5 and 6. A spade-shaped or pallet-shaped fastening member 12 encircles in a girdle-like manner the sponge 13, which is hinged to the handle 11. A hole 12a is provided approximately in the centre of the fastening member 12 and is surrounded by a wide frame, which is overlapped in use by parts of the sponge whereby pressure can be applied to the sponge 13 over a large area.. The sponge in this embodiment is provided on one side with a scouring layer 13a.
