The present disclosure relates generally to handles.
Pumice stones have a variety of uses, including as an exfoliator for removing rough, dry skin from a user's body (e.g., a user's heels) and as a cleaning product (e.g., a scouring product for removing mineral deposits, rust, and/or stains on household appliances). Pumice stones used in the cleaning of appliances with potential hazardous waste such as a toilet or urinal, are typically provided with a handle to protect the user from direct contact with the appliance containing said waste. However, conventional handles may be prone to detaching from the pumice stone, which makes it difficult or impracticable to use the pumice stone. Additionally, conventional handles for pumice stones consume a lot of material and these materials may not be recyclable. Accordingly, many conventional handles for pumice stones are not environmentally friendly. Furthermore, many conventional handles for pumice stones are not ergonomically shaped to be comfortably grasped by a user, which may result in discomfort and/or fatigue in the user's hand while using the pumice stone.
The present disclosure is directed to various embodiments of a handle configured to support a pumice stone or other object. In one embodiment, the handle includes a gripping portion and a support portion extending from the gripping portion. The support portion is configured to support the pumice stone or other object. The support portion includes a post, a series of ribs spaced apart along a length of the post, and a series of cavities defined between adjacent ribs. The series of cavities is configured to accommodate an adhesive for coupling the support portion of the handle to the pumice stone. The handle may include a base member between the gripping portion and the support portion. The support portion extends from a first surface of the base member and the gripping portion extends from a second surface of the base member opposite to the first surface. Adjacent ribs may be spaced apart by a distance from approximately ⅛ inch to approximately ½ inch. The post of the support portion may include first and second struts arranged in a cross shape. Each rib may include a series of rib segments arranged in a common plane. Each rib segment may be a quadrant. Each of the rib segments may extend between the first and second braces. The handle may be made of polypropylene, such as a pure polypropylene suitable for level 5 recycling.
In another embodiment, the handle includes a support portion configured to support the pumice stone and a gripping portion extending from the support portion. The gripping portion includes a first arm, a second arm spaced apart from the first arm, a substantially planar platform extending between the first arm and the second arm, and an interconnecting portion extending between distal ends of the first and second arms. The first and second arms and the platform may define a first opening proximate to the support portion and a second opening proximate to the interconnecting portion. An upper surface of the each of the first and second arms may be curved away from a lower surface of a corresponding arm of the first and second arms. A lower surface of each of the first and second arms may define a recess. The platform may include at least one indicium, such as a recycling symbol, a trademark, and/or an identification of a material of the handle. The handle may also include base member between the gripping portion and the support portion. The support portion extends from a first surface of the base member and the gripping portion extends from a second surface of the base member opposite to the first surface.
The present disclosure is also directed to various embodiments of a pumice stone device. In one embodiment, the pumice stone device includes a pumice stone defining an opening and a handle attached to the pumice stone. The handle includes a gripping portion and a support portion extending from the gripping portion. The gripping portion of the handle includes a first arm, a second arm spaced apart from the first arm, a substantially planar platform extending between the first arm and the second arm, and an interconnecting portion extending between distal ends of the first and second arms. The support portion of the handle extends into the opening in the pumice stone. The support portion includes a post, a series of ribs spaced apart along a length of the post, and a series of cavities defined between adjacent ribs. The pumice stone device also includes an adhesive in the plurality of cavities securing the handle to the pumice stone. The adhesive may be a hot melt glue. The handle further may include a base member between the gripping portion and the support portion supporting an end of the pumice stone. The first and second arms and the platform may define a first opening proximate to the base member and a second opening distal to the base member. The platform may include at least one indicium, such as a recycling symbol, a trademark, and/or an identification of a material of the handle.

With continued reference to the embodiment illustrated in
In one or more embodiments, the support portion 102 may have any other configuration suitable for attaching the handle 100 to the pumice stone P. For instance, in one or more embodiments, the support portion 102 may be provided without the ribs 107 (e.g., the support portion 102 may be provided with only the post 106 and the post 106 may have any suitable shape, such as a cylindrical rod, a tapered cylindrical rod, a prismatic shape, such as a square prismatic shape, or a tapered prismatic shape, such as a frusto-pyramidal shape). In one or more embodiments, the support portion 102 of the handle 100 may be provided without the ribs 107 and the cavities 113 may be defined directly in the post 106 (e.g., the cavities 113 configured to receive the adhesive may be defined by recesses directly in the post 106 rather than by the ribs 107).
In the illustrated embodiment, the gripping portion 101 of the handle 100 includes a pair of arms 114, 115 each having a proximal end 116, 117 at the base member 103 and a distal end 118, 119 opposite to the proximal end 116, 117, respectively. In the illustrated embodiment, the arms 114, 115 are spaced apart from each other by a gap 120. In one or more embodiments, the gap 120 may be from approximately 0.5 inch to approximately 1 inch. Additionally, in the illustrated embodiment, the arms 114, 115 are curved outward with respect to a centerline L of the gripping portion 101, although in one or more embodiments, the arms 114, 115 may be parallel or substantially parallel to the centerline L of the gripping portion 101 or may curve inward with respect to the centerline L. Curving the arms 114, 115 outward with respect to the centerline L of the gripping portion 101 is configured to provide an ergonomic configuration for a user to grasp the gripping portion 101.
Additionally, in the illustrated embodiment, the gripping portion 101 includes an interconnection portion 121 extending between and interconnecting the distal ends 118, 119 of the arms 114, 115. In the illustrated embodiment, the interconnection portion 121 is rounded (e.g., having a radius from approximately ¼ inch to approximately ½ inch, such as, for instance, approximately ⅜ inch), although in one or more embodiments, the interconnection portion 121 may have any other suitable shape, such as straight.
In the illustrated embodiment, the gripping portion 101 also includes a platform 122 extending between the arms 114, 115. In the illustrated embodiment, the platform 122 is a generally planar rectangular member, although in one or more embodiments, the platform 122 may have any other suitable shape. The platform 122 is configured to increase the structural rigidity of the gripping portion 101 by, for example, preventing the arms 114, 115 from moving closer toward each other when a user grasps the gripping portion 101. Additionally, various indicia 131 may be provided on one or more surfaces of the platform 122, including trademark indicia, a recycling symbol configured to promote recycling the handle, and/or an identification of the material of the handle 100. The indicia 131 may be provided on an upper surface 132 and/or a lower surface 133 of the platform 122.
Additionally, in the illustrated embodiment, the platform 122 does not extend completely to the proximal ends 116, 117 of the arms 114, 115 at the base member 103 and does not extend completely to the interconnection portion 121 at the distal ends 118, 119 of the arms 114, 115. Accordingly, in the illustrated embodiment, a pair of openings 123, 124 are defined at opposite ends of the gripping portion 101 (i.e., a proximal opening 123 is defined between a proximal end of the platform 122 and the base member 103 and a distal opening 124 is defined between the distal end of the platform 122 and the interconnection portion 121). The openings 123, 124 are configured to permit the handle 100 to be displayed in a retail store, such as, for instance, hung on a hook in a retail store display. Although in the illustrated embodiment the gripping portion 101 defines two openings 123, 124, in one or more embodiments, the gripping portion 101 may define a single opening (e.g., the distal opening or the proximal opening).
With continued reference to the embodiment illustrated in
