Description

Brush

The invention relates to a brush according to the preamble of claim 1 having a body and a shaft having an shaft and a handle or handle fastener.

The invention also relates to a method for making a brush according to the preamble of claim 9.

To effectively scrub and brush the floor or similar substrate, the surface of the brushed brush should be as large as possible, while still being easy to handle. This is especially important if the brush is a so-called scrubbing brush intended primarily for washing floors and scrubbing, as the bristles must be relatively stiff to remove dirt from the substrate. The scrubbing brush should also be sufficiently robust in structure and easy to manufacture, for example for serial production.

The foregoing objects of the invention are achieved by a brush according to claim 1, the frame of which comprises two parallel sections spaced apart by a bridge.

Specifically, the brush according to the invention has a body and a shaft having an axis and a handle or handle attachment. The body comprises two body parts, each of which has a bundle of bristles attached to its lower surface.

The frame members are interconnected by a fixed bridge so that their longitudinal axes run parallel. The bridge comprises a pair of bridge members consisting of two bridge members spaced apart at a longitudinal distance from the ridge, each bridge member having a first coupling element for integrally connecting the frame members, and a second coupling element 25 for coupling the shaft of the shaft to the bridge members. Here

the bristle bundles (3; 31,32) located on the underside of the body members (21,22) are identical or different from each other and comprise a plurality of rigid bristles facing downwardly from the underside (21b, 22b) of the body members (21,22), made of plastic;

- the first coupling element of each bridge section comprises a horizontal plate-like fastening element engaging the inner surfaces of the two frame sections to which a second coupling element is coupled. Said second coupling element comprises an upwardly supporting arm which engages at its lower end

20146111 prh 20 -06-2018 to said first coupling element and a sleeve at the free end of the support arm, the sleeve extending above the level of the upper surface of said body members;

- the shaft of the arm is elongate and extends in the longitudinal direction of the body members and is pivotally supported on the sleeves in the transverse direction of the brush body;

- the shaft of the shaft further comprises an articulated member for pivotally engaging the shaft handle or handle mount in the longitudinal direction of the brush body.

Preferably, the body of the brush according to the above-mentioned invention, as well as the arm coupled to the body, is made entirely or mainly of plastic.

In a preferred embodiment of the invention, the bundles of bristles located on the underside of the body members comprise a plurality of rigid bristles downwardly facing the underside of the body members, preferably made of plastic.

When the body of the brush according to the invention, and possibly also the bristles thereof, are made of plastic, it can be manufactured simply by injection molding using the method according to claim 10.

In the method of making the brush according to the invention, wherein at least the brush body is made of plastic, the method comprises at least the following process steps:

- injection molding the base of the bristle body parts and the lower part of the fixed bridge connecting them,

- providing the base portions of the body members with bristles, preferably comprising a plurality of rigid plastic bristles.

- injection molding the tops of the body members and the upper part of the fixed bridge 25 connecting them to the bottom parts of the body parts having bristles.

If the bristles are made of the same plastic material as the base parts of the frames, they can be made in the same context as the base parts of the frames.

In a preferred embodiment of the invention, the base portions of the bristle-mounted body members 30 and the lower portion of the fixed bridge connecting them comprise at least

20146111 prh 20 -06-2018 the major part of the first coupling elements of the plate-like fastening elements and the upper parts of the frame members and the solid bridge connecting them thereto comprise at least the major part of the second coupling elements.

The brush according to the invention is based firstly on the brush having two parallel body members with rigid bristles, which are connected by a fixed bridge provided by first coupling elements engaging the inner surfaces of the body members, comprising horizontal plate fastening elements. This bridge further comprises second coupling elements having in each case an upright, preferably perpendicular, upwardly pivoting arm and a sleeve at the free end of the pivoting arm which extends above the upper surface level of said frame members. The elongated shaft of the shaft can now be pivotally mounted on the sleeve in the transverse direction of the body to allow transverse movements of the shaft. Secondly, the invention is based on the fact that the shaft of the shaft further comprises a pivot part, preferably a plate-like pivot part, for pivotally engaging the shaft handle or handle mount in the longitudinal direction of the brush body.

Such a scrubbing brush, which is intended for washing the floor or similar substrate, has a wide base area to which rigid bristles can be attached, but since the bristles are divided into two separate body parts, the brush is easy to handle. This is especially important if the brush is primarily intended for scrubbing floors, whereby the bristles must be relatively stiff to remove dirt from the substrate.

In a preferred embodiment of the invention, the body of the scrub brush can be simply made by injection molding. The advantage of such a manufacturing method is that the structure of the brush body is strong.

From GB 2434971, a dryer blade is known in which the bridge structure connecting the wiper holders 18, 120 does not integrate said wiper holders. In the embodiment of the invention shown in Fig. 4, the bridge structure even allows the mutual movement of the holders 14, 16. In the embodiment of Figures 1-3, the bridge structure is more robust but not fixed and further requires support members 24 which connect the ends 14, 16 to the ends. In the present invention, the first coupling elements of the bridge sections are engaged by bristles

20146111 prh 20 -06-2018 fixed to the inner surface of the frame members, providing a significantly more robust connection between the bridge and the frame members than in D1. This is a significant advantage in scrubbing, where the bridge is subject to considerable stress.

The brush-like brush of claim 1, but apparently mainly intended for removing debris, is known from FR2752717A1. The structure of this brush body and the bridge to which it is attached appear to be questionable in durability and specifically in scrubbing applications.

The brush structure described in this document D2 FR2752717 differs from the scrub brush bridge structure disclosed in the present application in that the bridges frame members which correspond to the first coupling elements of the bridge according to the invention do not engage the bristle frame parts. In addition, the bridging structure of the publication does not connect the frame members to one another, but detachably with screws or the like.

Also, it is not possible to produce the body of this brush by mass injection molding.

In addition, the handle coupled to the brush known from FR2752717A1 can only be pivoted in the transverse direction of the brush, while the handle of the brush according to the invention can be pivoted relative to the brush body both in the length 20 and in the transverse direction of the brush body.

In a preferred embodiment of the invention, the lower portion of the handle handle or handle mount has a fork and the shaft has a plate-like hinged portion that is slidable and engages with the fork. This can provide a pivot joint that allows the handle or handle handle to be pivoted, the pivot point being the center of the pivot movement, in the direction of the plane of the plate-like pivot part, i.e. in the longitudinal direction of the body. Further, the arm can be coupled to the bridge such that its handle or handle mount can be supported by an axle, pivotally longitudinally of the body members, on the sleeves of the bridge. In this way, the handle handle or handle mount can be pivotally coupled to the body in the longitudinal and transverse directions of the body members.

Such a fork-mounted handle is simply and quickly coupled to an articulated member of the shaft, e.g.

20146111 prh 20 -06-2018 plate-like piece that allows fork-to-plate pivoting while allowing arm to pivot in the plane of the plate.

In a preferred embodiment of the invention, the support arms of the second coupling elements extend vertically upwards from the horizontal plate-like fastening elements so that a constant distance is maintained between them. Preferably, the first coupling elements of the bridge frame members, i.e. the horizontal plate-like fastening elements, are located entirely in the space between the inner surfaces of the frame members. Such a bridge structure securely interconnects the brush body parts.

In another preferred embodiment of the invention, the underside of the plate-like fixing element of the bridging bridge is at the level of the underside of both frame members. This provides the advantage that the bottom parts of the frame members and the lower part of the bridge (lower surface of the plate-like fastening element) can be injection molded at the same time.

The brush of the invention having two pairs of bridges connected together by a pair of bridges provides the additional advantage that the bristle body of the bracket allows the floor to be scrubbed conveniently around obstacles such as the floor-mounted cabinet legs and the like.

In the following, the invention and the additional advantages thereof will be described with reference to the accompanying drawings, in which:

Figure 1 shows the brush as seen from the front.

Figure 2 shows the brush as viewed directly at one end.

Figure 3A shows the brush from above.
