Claims
1. A squeegee comprising: a wiping blade comprising a resilient strip supported by a relatively rigid support structure, said support structure having a first portion supporting a first part of said resilient strip and a second portion supporting a second part of said resilient strip; and a hollow semi-cylindrical handle with an extensional direction perpendicular to a length of the wiping blade.
2. The squeegee of claim 1, wherein one end of the handle is rigidly attached to or integrally formed with the support structure such that one side of the handle connects to the first portion of the support structure while the opposite side of the handle connects to the second portion of the support structure.
3. The squeegee of claim 2, wherein the handle further comprises protrusions extending outward therefrom.
4. The squeegee of claim 2, wherein the handle includes an inner surface defining a longitudinal cavity, and an outer surface, and upon application of force on the outer surface toward the cavity, the handle is compressed inward along its entire length such that the support structure is folded along a pivot axis thereby causing the squeegee to transition from a straight state to a folded state.
5. The squeegee of claim 1, further comprising a blocking element in the center of the blade.
6. The squeegee of claim 1, wherein the blade includes upright portions at each longitudinal end extending perpendicular to the length of the blade.

DETAILED DESCRIPTION
[0027] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the presently disclosed subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the presently disclosed subject matter.
[0028] Bearing this in mind, reference is now made to
[0029] The squeegee further includes a handle arrangement, with an extensional direction perpendicular to a length of the wiping blade 10 (for example the length of the wiping edge of the blade). The handle arrangement includes a first handle portion 16a rigidly attached to or integrally formed with the first portion 12a of the support structure, and a second handle portion 16b rigidly attached to or integrally formed with the second portion 12b of the support structure. The first and second handle portions 16a, 16b are hingedly interconnected so as to define a pivot axis 30 parallel to the extensional direction of the handle arrangement, such that the pivotal motion of the first handle portion 16a relative to the second handle portion 16b (or vice versa) about the pivot axis 30 results in reconfiguration of the wiping blade 10 from a straight state to a folded state, whereby the wiping blade 10 is folded along a pivot axis parallel to the extensional direction of the handle arrangement.
[0030] For greater clarification
[0031] As shown in
[0032] It should be appreciated that hingedly interconnected can include, for example where the handle portions are connected via integral hinge(s) or a mechanical hinge, and that such a hinge may have spring-like properties which force the squeegee into a straight state by default (i.e. in the absence of any pivotal motion by the user). In other embodiments, the resilient property of the strip of the wiping blade strip can force the wiping blade to a default straight state. In still other embodiments, the squeegee may further include a spring (not shown) or similar mechanism to automatically return the wiping blade to a straight state.
[0033] In certain embodiments, one or both of first and second handle portions 16a, 16b can optionally include one or more protrusions 18 extending outward from the handle portion(s), e.g. in a direction perpendicular to, or at an angle relative to, the extensional direction of the handle arrangement, further allowing a user to grasp and pivot the first and/or second handle portion to bring the wiping blade into a folded state.
[0034] In certain embodiment, the handle arrangement can have an extensional direction other than perpendicular to the length of the wiping blade. For example, the handle arrangement can be angled relative to the length of the wiping blade.
[0035] In a most particularly preferred embodiment, the support structure and handle portions are all integrally molded with an integral hinge, in order to simplify the manufacturing process, possibly using overmolding to integrate the resilient strip.
[0036] Reference is now made to
[0037] The phrase relatively rigid is used herein in the specification and claims to contrast to the flexibility required by a wiping blade structure, and refers to any structure which provides sufficient rigidity of support to allow the blade to be pressed evenly in sealing contact with an underlying surface. The support structure is relatively rigid in that it is more rigid than the blade. The rigidity may be imparted either through choice of a relatively rigid material, such as various thermoplastics, or by varying the relative dimensions and/or cross-sectional shape to provide the desired level of rigidity.
[0038] In certain embodiments, the unitary block of elastomeric material is thicker at the support structure than the blade, as shown in
[0039] The embodiment shown in
[0040] Optionally, the first portion 12a of the support structure can include a first blade support portion (not shown) extending parallel to the first part 14a of the resilient strip and a first handle portion (not shown) integrally formed with the first blade support portion, and the second portion 12b of the support structure can include a second blade support portion (not shown) extending parallel to the second part 14b of the resilient strip and a second handle portion (not shown), integrally formed with the second blade support portion, both the first and second handle portions having an extensional direction parallel to the pivot axis 30.
[0041] In a particularly preferred embodiment the wiping blade 10 is elongated and made of a continuous resilient strip, although in other embodiments the resilient strip can be formed from two or more strips joined together.
[0042] A variant of the hinged squeegee disclosed herein is shown in
[0043] A further embodiment of the hinged squeegee is shown in
[0044] The squeegee further includes a hollow semi-cylindrical handle 36, with an extensional direction perpendicular to a length of the wiping blade 10 (for example the length of the wiping edge of the blade). One end of handle 36 is rigidly attached to or integrally formed with, the blade support structure such that one side 37a of the handle connects to the first portion 12a of the support structure while the opposite side 37b of the handle connects to the second portion 12b of the support structure. Handle 36 can optionally include protrusions 18 extend outward therefrom. The semi-cylindrical handle 36 can also be shaped in a variety of different ways (such as a bulging out in the center, etc.).
[0045]
[0046]
[0047] In an alternative variant, the upright portions can 11a, 11b can be part of the support structure. It should be appreciated that upright portions 11a, 11b can be made of any suitable material.
[0048] It should be understood by those skilled in the art that the different features attributed to different embodiments disclosed herein can be combined to form many different variations of the embodiments disclosed herein, each of which is contemplated as being within the scope of the present subject matter.
[0049] It should be appreciated that the various embodiments described throughout this disclosure also contemplate variants in which the pivot axis is not centered precisely at the midpoint of the support structure and/or blade.
[0050] Although the squeegees described above and with reference to
[0051] It is to be understood that the invention is not limited in its application to the details set forth in the description contained herein or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Hence, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing other structures, methods, and systems for carrying out the several purposes of the presently disclosed subject matter.
[0052] Those skilled in the art will readily appreciate that various modifications and changes can be applied to the embodiments of the invention as hereinbefore described without departing from its scope, defined in and by the appended claims.
