The subject matter disclosed herein generally relates to plungers, toilet brushes, and caddy assemblies for storing plungers and toilet brushes.
The use of toilet bowl plungers for removing obstructions from toilet bowl drainpipes is well known. A toilet bowl plunger is typically used when a toilet bowl drainpipe (e.g., trap) becomes obstructed with waste matter or is otherwise clogged. The obstruction prevents water and other matter from flowing from the toilet bowl.
A typical toilet bowl plunger comprises an elongated handle and an inverted cup-shaped plunger portion connected to an end of the handle. The plunger portion is formed of rubber or some equivalent resilient material. When the trap becomes obstructed, the open end of the plunger portion is placed over the opening at the bottom of the toilet bowl and the walls of the plunger portion are rapidly collapsed in response to a downward push on the handle, thereby forcing air and/or water (under pressure) into the trap. The plunger portion is then rapidly returned to an initial shape by a user pulling upwardly on the handle, thereby applying suction to the trap. The resulting agitation tends to dislodge and free the obstruction from the trap.
A drawback to the use of conventional toilet bowl plungers is that during the process of dislodging the obstruction from the toilet trap, the plunger portion of the plunger comes into contact with unsanitary waste material. Such plunging action (compression and suction) can cause splashing of the water within the toilet bowl, which may be undesirable for the user. This splashing issue may be further exacerbated by the rapid and uncontrolled collapsing of the walls of the plunger portion. These issues may be exacerbated by high-efficiency toilets that may have non-circular trap designs that improve waste removal flow with less water usage. Further, after use, the plunger must be cleaned to ensure proper sanitary conditions. Accordingly, improved plungers and systems may be advantageous.

It should be understood, however, that the following description and drawings are intended to be illustrative and explanatory in nature and non-limiting.
The subject matter is particularly pointed out and distinctly claimed at the conclusion of the specification. The foregoing and other features, and advantages of the present disclosure are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
Referring to
As shown in
The handle engagement portion 106 is configured to securely and fixedly engage with the handle 104. Generally, the material thickness of the plunger member 102 may be substantially uniform. However, in some embodiments, the handle engagement portion 106 may include increased material wall thickness in order to support the engagement with the handle 104. Further, in some embodiments, at least a portion of the contact rib 110 may include an increased material thickness as compared to the compression ribs 108a-108c. The increased material thickness of the contact rib 110 may be provided to ensure an improved engagement and sealing contact with a bowl of a toilet to ensure a seal about the drain of the toilet, thus improving the plunging action while reducing the risk of splashing of water in the toilet.
The compression ribs 108a-108c are configured to stack over and into each other during compression and plunging of the plunger member 102. That is, in a direction from the handle engagement portion 106 toward the contact rib 110, the compression ribs 108a-108c may progressively increase in size. As such, during a compression and plunging action of the plunger member 102, a first compression rib 108a will compress and form, fit, or nest into the next largest compression rib (a second compression rib 108b in this embodiment). The second compression rib 108b will compress into and fit or nest into a third compression rib 108c. Although shown in this embodiment with three compression ribs 108a-108c, those of skill in the art will appreciate that any number of compression ribs may be employed without departing from the scope of the present disclosure. For example, in some embodiments, a single compression rib may be arranged between the handle engagement portion 106 and the contact rib 110. In other embodiments, two, three, four, or more compression ribs may be used. As described herein, the ribs of the plunger members may nest or fit within each other. To achieve such a nesting, each successive rib may have a smaller diameter or smaller shape/dimension than the next/adjacent rib. As such, when one rib section is pushed downward into the adjacent rib, the edges of the ribs are not aligned, but rather the smaller rib structure fits within the next larger structure. Stated another way, nesting ribs of the present disclosure means that the outer periphery of one rib is smaller and inwardly disposed relative to the outer periphery of the next adjacent.
The compression ribs 108a-108c provide for a collapsible configuration that can lessen the amount of force used by a user when using the plunger to clear a clogged toilet. That is, the compression ribs 108a-108c of the present disclosure are an accordion structure. This geometry and tapered set of compression ribs allows a user to easily displace air from an interior of the plunger member 102 into the drain of a toilet without the need to apply excessive force and/or cause the plunger member from snapping or reacting quickly, which can cause splash or disrupt a sealed contact between the plunger member 102 and a toilet bowl.
The handle 104 includes a bulbous grip 114, a first shaft portion 116, and a second shaft portion 118. The bulbous grip 114 is a shaped head or handle portion that enables a user to more firmly grip and apply downward pressure upon the handle 104 to cause the plunging action with the plunger member 102. In an embodiment, the bulbous grip 114 includes a curved top portion having a first curvature, a pair of opposing sidewalls having a second curvature, and a pair of ends having a third curvature. In addition to providing a pleasing visually ornamental appearance, the bulbous grip allows the operator to distribute the force applied over a wider surface than prior art plunger handles to further facilitate controlling the compression/release action of the plunger portion. The first shaft portion 116 extends between the bulbous grip 114 and the second shaft portion 118 and is tapered. The size, shape, and length of the first shaft portion 116 may be selected for engagement with a caddy (described herein) to enable storage and drying of the plunger 100 after use. The second shaft portion 118 extends between the first shaft portion 116 and the handle engagement portion 106 of the plunger member 102. The second shaft portion 118 may also be tapered along a length thereof. The second shaft portion 118 includes a plunger engagement portion 120 that is configured to securely engage with the handle engagement portion 106 of the plunger member 102. The engagement between the handle engagement portion 106 and the plunger engagement portion 120 may be by a threaded connection, press-fit, snap engagement, pin-and-slot engagement, adhesive, fastener engagement, or other means or mechanism for joining the handle 104 to the plunger member 102. The handle 104 may be non-circular in cross-section, both along the first shaft portion 116 and the second shaft portion 118. This non-circular cross-section may assist in storage of the plunger 100 into a caddy, as described below.

As shown in
As shown, the progressive sizes of the compression ribs 208a-208c enables compression and nesting or stacking of the compression ribs into/onto each other during a compression action. Further, as shown, the contact rib 210 includes an increased wall thickness section 218 relative to the wall thickness of the compression ribs 208a-208c. The increased wall thickness section 218 of the contact rib 210 is arranged facing downward and defines the portion of the plunger member 202 that contacts and sealingly engages with a surface of a toilet bowl. The increased wall thickness section 218 provides for increased structural rigidity to the material of the plunger member 202 such that a proper seal is formed and maintained during a plunging action. In other words, the increased wall thickness reduces the risk of the increased wall thickness section 218 deforming during use and disrupting the seal with the surface of the toilet. The increased thickness of the increased wall thickness section 218 may be between 5% and 50% thicker than the material that forms and defines the compression ribs 208a-208c.

As noted above, the non-circular shape of the plungers of the present disclosure is not limited to a single geometric shape. For example, referring to
In accordance with some embodiments, the engagement between the plunger member and the handle may include features to enable alignment and desired orientation of the components to ensure a desired and secure engagement and connection of the two parts. Because the handle and/or plunger member may be non-circular, an alignment of the handle relative to the plunger member may be desired to allow the plunger member to be positioned in a desired orientation within a caddy or holder as is discussed in more detail herein.
For example, referring to
The plungers described herein include a non-round or non-circular plunger member, which in addition to providing a pleasing visual ornamental appearance, also provides for an improved sealing engagement with a toilet bowl surface. Further, the non-circular shapes can provide for improved and efficient downward (compression) action for unclogging toilets and pushing water down into the pipes. The non-circular shapes may also provide for a gradual, but strong and effective, thrust via a stepped bellows/pleats design, as shown and described herein. This stepped bellows/pleats design may reduce a “snapping” action inherent in conventional bell or globe shaped plungers. Further, the stepped bellows/pleats design (e.g., accordion style) plunger member helps with force application, preventing rapid collapsing of the plunger walls and snap-back of the plunger member to reduce the risk of splash back of water from the toilet. The bulbous grip on the handle, which in addition to providing a pleasing visual ornamental appearance, provides for an increase in surface area that a user can grip and engage with a palm to apply force during plunging. In accordance with some embodiments, the plunger member may be formed from non-rigid materials. For example, some prior plungers were formed using plastic materials. However, in accordance with embodiments of the present disclosure, the plunger member may be made from non-plastic materials, such as rubbers, elastomers, thermoplastics, and the like. In accordance with some embodiments, the material may be selected to further assist in the plunging action, including the use of a pliable material that can work with the accordion shape of the plunger member for smooth compression and release actions of the plunger during use. In accordance with some embodiments of the present disclosure, the accordion configuration, the selection of the materials, and the non-circular shape can all present a desired force application in both the compression stage and the release stage of a plunging action. In some embodiments, the same force applied to compress is achieved in the release. This is in contrast to conventional bell-plungers, which may generate an excessive release force (rapid collapse and snap back) which can cause splash or lack of manual control of the plunger.

The plunger 502 includes a handle having one or more tapered portions 510a, 510b and a bulbous grip 512. At least one of the tapered portion 510a, 510b may be configured to be received or engage with a holder 514 of the caddy 504. The holder 514 includes two arms 516a, 516b that define a tapered, conical, or funnel-like channel or cavity for receiving and engaging with a portion of the handle. For example, as shown, the tapered portion 510a of the handle of the plunger 502 can be fittingly received and supported by the holder 514 of the caddy 504. The holder 514 also includes an optional tab 518 which, in addition to providing a pleasing visual ornamental appearance, may be used for ease of picking up the caddy 504 with or without the plunger 502 installed therein.
The caddy 504 includes a body 520 with the holder 514 at a top side thereof. The body 520 of the caddy 504 defines an interior cavity for receiving the plunger member 506 of the plunger 502. At the bottom of the body 520 is a base 522. The base 522 is shaped to allow for a gap 524 to be present between a bottom of the plunger member 506 and the material of the base 522. As such, air may be able to flow between the interior cavity of the caddy 504 (e.g., ambient air) and an interior of the plunger member 506. This fluid connection through the gap 524 can aid in drying the plunger member 506 after use, preventing stagnant water/air from being trapped within the plunger member 506.

In other embodiments, the three components of the assembly base 710 may be uniformly or integrally formed as a single structure/body, such as by molding or machining. Still, in other embodiments, the portions 712, 714, 716 may be formed or made separated and then assembled using fasteners, glue, adhesives, bonding, welding, or the like, as will be appreciated by those of skill in the art.
Advantageously, embodiments described herein provide improved plungers and cleaning implement assemblies. The plungers described herein improve plunging action through improved force application by including a bulbous grip on the handle and a non-circular plunger member. The non-circular plunger member provides for improved sealing between the plunger member and a surface of a toilet bowl. The improved seal can enable improved compression/release action to unclog a clogged drain. Further, the non-circular shape can eliminate, reduce, or minimize splash back of water during a plunging action.
The non-circular plunger members can also include an increased wall thickness or material thickness at the location where the plunger member contacts the toilet bowl. This increased material or wall thickness ensures a desired seal and provides for structural and/or mechanical strength at the contact surface between the plunger and the toilet bowl. The increased thickness may be present only on a contact rib of the plunger member, and other compression ribs may be provided to form an accordion-style plunger, which enables controlled force application both on the downward compression action and the upward release action during a plunging action.
Further, advantageously, caddies are provided herein for the non-circular plungers. The caddies can provide storage or stowage for the plunger in a housing that can suspend the plunger with an air gap between the plunger and a base of the caddy. This gap may improve drying of the plunger after use. Further, the caddy may be an adjustable structure that can be oriented in a desired way by a user. Double caddies can accommodate both a plunger and a toilet cleaning brush or other cleaning implement. The double caddy may be customizable at least with respect to the orientation of each caddy of the double caddy system. A single assembly base may be provided to receive each of a first caddy (for a plunger) and a second caddy (for a brush), and permit adjustment of the two caddies relative to each other. Furthermore, the assembly base can enable removal of one or both caddies during use, and serve as a single location to store the caddies and cleaning implements when not in use.
It should be appreciated that the particular shapes, relative sizes and configurations of the components illustrated in the drawings may be chosen for a desired ornamental appearance and the functions described herein may be performed by components having a different size, shape, and/or configuration in accordance with, and without deviating from, the teachings provided herein. For example, the bodies of the caddies may have square or circular shapes rather than a wall that curves in two directions, or the assembly base may have a different shape (e.g., circular) than the caddy bodies.
