Disclosure of Invention

The present utility model provides a scraper member that can be used by a user in two modes of operation, pushing or pulling the scraper member over a surface to be cleaned. In order to obtain an optimal scraper member which can perform cleaning in two modes in an optimal manner, the scraper member comprises two wiping portions, each intended for a different operating mode. That is, one of the wiping portions is intended to be used in a pull mode, while the other wiping portion is intended to be used in a push mode.

The scraper comprises a handle or bar receiver for receiving a handle/bar manipulated by a user to perform a cleaning task with the scraper, and each of the wiping portions is oriented differently relative to the handle receiver, thereby defining a desired mode of operation of the wiping portion. For example, the first wiping portion may define a plane substantially parallel to a handle receiver axis defined by the handle receiver, whereby the first wiping portion is intended to be used in a pulling mode of operation. The second wiping portion may define a plane substantially perpendicular to the handle receiver axis, so the second wiping portion is intended to be used in a push mode of operation.

It should be noted that throughout the application, the term "substantially" in the context of an angle should be understood as deviating from the nominal value by ±30°. For example, the term "substantially parallel" should be understood as ranging from-30 ° to 30 °, while the term "substantially perpendicular" should be understood as ranging from 60 ° to 120 °.

The transition between the two modes of operation is accomplished by rotating the scraper member about 180 ° about the handle receiver axis.

Throughout this application, references to the term "about" with respect to angle should be interpreted as deviations of + -20 deg.. For example, about 180 ° should be construed as a range between 160 ° and 200 °.

Accordingly, a first aspect of the present utility model provides a scraper comprising a scraper base portion extending along a base axis between a first end and a second end. The scraper also includes: a first wiping portion defining a first wiping portion plane, the first wiping portion extending from the base portion and having a first wiping edge; and a second wiping portion defining a second wiping portion plane extending from the base portion and having a second wiping edge, the second wiping portion plane forming an angle with the first wiping portion plane. The handle receiver protrudes from the scraper base portion and optionally a portion of the handle receiver also protrudes from one of the first wiping portion or the second wiping portion. The handle receiving portion is configured to receive a handle to allow a user to use the scraper. Further, the handle receiver defines a handle receiver axis, and the handle is aligned with the handle receiver axis when the handle is received in the handle receiver.

The handle receiver axis (i) is substantially parallel to the first wiper portion plane, i.e. forms an acute angle of up to + -30 deg. with the plane, and the handle receiver axis (ii) is substantially perpendicular to the second wiper portion plane, i.e. forms an acute angle with the plane of between 60 deg. and 90 deg. (making the acute angle a right angle). This structural configuration facilitates a pull wipe with the first wipe portion and a push wipe with the second wipe portion.

It should be noted that any combination of the described embodiments is applicable in respect of any aspect of the utility model. In other words, any aspect of the utility model may be defined by any combination of the described embodiments.

In some embodiments of the scraper, the handle receiver axis forms an acute angle of about 15 ° with the first wiping portion plane.

In some embodiments of the scraper, the handle receiver axis forms an acute angle of about 85 ° with the second wiping portion plane.

In some embodiments of the scraper, the scraper base comprises a planar face defining a face plane. The handle receiver protrudes from the planar face and the handle receiver axis is perpendicular to the face plane.

In some embodiments of the scraper, the first wiping part plane forms an angle with the second wiping part plane that is substantially right angle. Accordingly, the angle formed between the first wiping part plane and the second wiping part plane is defined between 60 ° and 120 °.

In some embodiments, the first wiping portion plane forms an angle of about 65 ° with the second wiping portion plane.

In some embodiments of the wiper, the wiper base, the first wiping portion, the second wiping portion, and the handle receiver are formed as a one-piece molded article. That is, the wiper is a one-piece molded article formed from a single mold.

In some embodiments, the scraper is made of rubber or silicone rubber.

In some embodiments of the wiper, each of the first and second wiping portions includes a tapered portion that terminates at the first and second wiping edges, respectively.

In some embodiments of the wiper, the first wiping portion plane and the second wiping portion plane are defined by a first wiping edge and a second wiping edge, respectively. I.e. the direction in which the wiping edge points defines the respective plane.

In some embodiments of the scraper, a portion of the handle receiver protrudes from the base portion and a portion of the handle receiver protrudes from the second wiping portion. When a force is applied by the user through the manipulation handle, the force is applied on the portion of the second wiping portion closest to the base portion, which is important for operation in the push mode, optimizing use in the push mode.

In some embodiments of the scraper, at least one of the first wiping portion and the second wiping portion extends between the first end and the second end. That is, the width of the first wiping portion and the second wiping portion is defined as the distance between the first end and the second end. In some embodiments of the scraper, either the first end or the second end extends between the first end and the second end.

In some embodiments of the scraper, the handle receiver includes a main receiver body and two support legs that combine with the main receiver body and the base portion for providing additional support to the handle receiver. Each of the support legs protrudes from opposite sides of the main receiver body and is joined with a portion of the base portion on opposite sides of the handle receiver.

In some embodiments of the scraper, the support leg and the main receiver body together define a handle receiver plane on which the handle receiver axis lies.

In some embodiments of the scraper, the handle-receiving portion plane forms an acute angle of about 15 ° with the first wiping portion plane.

In some embodiments of the scraper, the handle-receiving portion plane forms an acute angle of about 85 ° with the second wiping portion plane.

In some embodiments of the scraper, the handle receiver may include a main receiver body and two support legs that are coupled with the main receiver body and the scraper base portion for providing additional support to the handle receiver, each of the support legs protruding from opposite sides of the main receiver body and being coupled with a portion of the scraper base portion.

In some embodiments of the wiper, the support leg and the main receiver body may together define a handle receiver plane, the handle receiver axis being located on the handle receiver plane, wherein the handle receiver plane forms an acute angle of up to 30 ° with the first wiping portion plane and the handle receiver plane forms an acute angle of between 60 ° and 90 ° with the second wiping portion plane.

In some embodiments of the scraper, the second wiping portion extends from the base portion to a greater extent than the first wiping portion extends from the base portion. That is, the second wiping portion is longer than the first wiping portion.

In some embodiments of the scraper, the first and second wiping portions are comprised of first and second tapered structural members. The first tapered structure extends a length L from the base portion ₁ While the second tapered structure extends a length L from the base portion ₂ Wherein L is ₂ >L ₁ . This design allows the scraper member to be used as a pushing scraper member in an optimal manner, i.e. at an optimal angle of engagement of the second wiping part with the surface to be cleaned, without the first wiping part interfering with the cleaning action, i.e. without the first wiping part engaging with the surface.

Drawings

For a better understanding of the subject matter disclosed herein and to enumerate how the subject matter may be carried into practice, embodiments will now be described, by way of non-limiting example only, with reference to the accompanying drawings, in which:

fig. 1A to 1E are schematic views of different views of a non-limiting example of an embodiment of a scraper according to aspects of the utility model. Fig. 1A to 1B are perspective views; FIG. 1C is a top view; FIG. 1D is a front view; and fig. 1E is a side view.

Detailed Description

The following drawings are provided to enumerate embodiments and implementations of the utility models of the present disclosure.

Referring to fig. 1A-1E, fig. 1A-1E are schematic views of different views of a non-limiting example of an embodiment of a scraper according to aspects of the utility model. The scraper 100 includes a base portion 102, the base portion 102 extending along a base axis BA between a first end 104 and a second end 106.

The handle receiver 108 at least partially protrudes from the base portion 102, and the handle receiver 108 is configured to receive a handle or a handle for allowing a user to manipulate the scraper 100. The handle receiver 108 defines a handle receiver axis HA. When the handle is received in the handle receiver 108, the handle is aligned with the handle receiver axis HA.

The scraper member 100 further includes a first wiping portion 110 and a second wiping portion 112 extending from the base portion 102 and joined to the base portion 102. The wiping portions 110 and 112 are tapered, each terminating at a respective wiping edge 114 and 116. That is, the wiping portion tapers from the base portion towards the respective wiping edge of the wiping portion. The wiping portions 110 and 112 define a first wiping portion plane FWP and a second wiping portion plane SWP, respectively. The first wiping part plane FWP forms an angle a with the second wiping part plane SWP, which angle is in the range of 50 ° to 130 °. In some embodiments, the angle α is between 50 ° and 70 °. Thus, the first wiping portion plane FWP and the second wiping portion plane SWP define the orientation of the wiping portions 110 and 112 relative to the handle receiver axis HA. The handle receiver axis HA forms an acute angle of up to 30 ° with the first wiping portion plane FWP. The handle-receiving portion axis HA forms an acute angle of 60 ° to 90 ° with the second wiping portion plane SWP, i.e. between 60 ° and exactly perpendicular to this plane.

By designing the scraper member with such a configuration, the user can use the scraper member in two different modes of operation, pulling and pushing. When the user uses the scraper in such a way that the first wiping part 110 engages the surface to be cleaned, the scraper is used as a pulling scraper, since the angle of engagement of the first wiping edge 114 with the surface and the force exerted on the first wiping part 110 by the user by manipulating the handle are optimal for the pulling use of the scraper. When the user uses the scraper in such a way that the second wiping part 110 engages the surface to be cleaned, the scraper is used as a pushing scraper, since the angle of engagement of the second wiping edge 116 with the surface and the force exerted by the user on the second wiping part 116 by manipulating the handle are optimal for pushing use of the scraper. By rotating the scraper member 100 about the handle-receiving portion axis HA, the user can easily change between the operating modes of the pushing operation and the pulling operation. The scraper members of the present utility model are designed to allow for changing modes of operation by rotating the scraper member generally 180 ° about the handle receiver axis.

The wiper is a one-piece molded article made of silicone rubber or silicone rubber. That is, the base portion, the first and second wiping portions, and the handle receiver are each made from a single mold and are one-piece. This also contributes to the physical properties of the scraper member for allowing the scraper member to be an effective pull/push scraper member.

The base portion 102 includes a planar face 103 defining a base portion plane BP. A portion of the handle receiver 108 protrudes from the planar face portion, and a portion of the handle receiver protrudes from the second wiping portion 112. Forming a portion of the base of the handle receiver 108 on the second wiping portion 112 facilitates operation in the push mode and makes operation in the push mode very efficient as a user applies a force vector on the second wiping portion by manipulating the handle received in the handle receiver 108.

The handle receiver axis HA is perpendicular to the base part plane BP and thus the base part plane BP forms an acute angle of 60 ° to right angle, i.e. to 90 °, with the first wiping part plane FWP and the base part plane forms an acute angle of up to 30 ° with the second wiping part plane SWP.

The handle receiver 108 includes a main receiver body 118 and two support legs 120, the two support legs 120 forming wings of the main receiver body 118 from opposite sides of the main receiver body 118. The legs protrude from the main receiver body 118 and extend to the base portion 102. The legs are joined to both the receiver body 118 and the base portion 102. Together, the support leg 120 and the main receiver body 118 define a handle receiver plane HRP and a handle receiver axis HA located in the plane. Similar to the handle receiver axis HA, the handle receiver plane HRP forms an acute angle with the first wiping part plane FWP and the second wiping part plane SWP. That is, the handle receiver plane HRP forms an angle of up to 30 ° with the first wiping part plane FWP, and the handle receiver plane HRP forms an acute angle between 60 ° and 90 ° with the second wiping part plane SWP.

The first wiping portion and the second wiping portion are formed of tapered structural members. The tapered structure of the first wiping portion extends from the base portion for a length L ₁ While the second wiping portion extends a length L from the base portion ₂ Wherein L is ₂ >L ₁ This can best be seen in fig. 1E. This is particularly important to allow the scraper to be used as a pushing scraper without disturbing the first wiping part.
