In general, the present embodiments relate to a handheld ergonomic device. The present embodiments may be adapted to accomplish a variety of tasks, including scrubbing, scraping, scooping, brushing, painting, marking, drawing, cutting, sanding, grating, shaving, among many other tasks. More particularly, the present embodiments feature an ergonomic handle that may be used in conjunction with other adjoining and complementary shapes, materials, surfaces, textures or tools.
Many consumer products incorporate a handle that enables a user to grasp, hold and manipulate the product. Different products feature different types of handles. Some handles are long and slender, while other handles may be short, round and similar in shape to a knob. Several factors contribute to the effectiveness of a handle. For example, a handle can perform effectively if it has sufficient strength to support the weight and various stresses that may be exerted upon the handle and the rest of the device. In addition, a handle must have sufficient length and overall surface area so that a user may grasp, hold and manipulate the device.
Not all handheld consumer objects have handles. Some objects, such as flat, foam scrubbing pads, do not have a specific handle, but rather the user must grasp the pad itself and maintain a grip on the pad without the use of a handle. Often the user must place their thumb on one side of the pad, while placing their other digits on the opposite side of the pad. This particular placement of thumb and other digits enables a user to squeeze the pad between the thumb and opposing digits. Further, the user often squeezes the pad into a shape that conforms to the shape that exists between the user's thumb and other digits. In this instance, the user has effectively created a type of handle by simply squeezing the pad into a shape that conforms to the natural contours that exist between the thumb and opposing digits.
The design of the handle is often dictated by the type of task that must be performed with the handle. Ergonomically designed handles contribute to the effectiveness of the handle and the object to which the handle is attached. In general, ergonomics is a science that is concerned with designing consumer products in a manner that makes the products easier and safer to use. A common ergonomic strategy involves the creation of various curved surfaces that are designed to correspond to the curved surfaces and mechanics of the human hand. Some products have handles that exhibit few ergonomic qualities, which results in a product that may be considered awkward, uncomfortable and somewhat ineffective or inefficient. Other products that exhibit greater ergonomic features are often considered more comfortable and effective.
Many handles employ a cylindrical design that includes a somewhat round or oval circumference. For example, paintbrushes often have long, slender, somewhat cylindrical handles. The long handle enables a user to wrap multiple digits around the handle. Paintbrushes, toothbrushes, hairbrushes, various kitchen utensils and shaving razors each have similar long, cylindrical, slender handles. Some scrub brushes have long handles, while others have short, knob-like handles. Short, knob-like handles are sometimes designed to enable a user to wrap their digits around the handle while placing their palm over the top of the knob-like handle. Placing the palm over the top of the knob-like handle enables a user to exert greater force upon the knob.
Many common products with long handles may be improved by employing a handle with a more compact, ergonomic design. Some common handles are unnecessarily bulky, cumbersome and lacking in versatility or ergonomic appeal. In some cases, a long handle may inhibit the user's ability to exert greater precision while using the device. A user is often able to exert more precise control over an object if the hand is closer to the surface upon which the product is making contact. A long handle may create distance between the user's hand and the end portion of the device which is performing a task such as painting, scrubbing or shaving. Thus, a shorter, more compact, ergonomic handle may offer a user greater control and precision over the product that is being manipulated. Some activities such as painting, scrubbing or shaving require greater precision, dexterity and control by the human hand.
In many cases, the user often holds the handle in a manner that enables their hand to be near the working surface. For example, when a user is shaving, the user exercises great care while manipulating the handle that is attached to the razor. In this instance, the user does not instinctively grasp the portion of the handle that is furthest away from the blade. Instead, the user grasps the portion of the handle that is closer to the blade. Grasping the portion of the handle that is closer to the blade gives the user a greater sense of confidence that they will not accidentally cut themselves with the blade.
A pencil may be used to further illustrate this ergonomic principle. When writing with a pencil, the user grasps the pencil near the writing portion of the pencil, which enables the user to rest or stabilize their hand on the writing surface. This stabilizing posture allows the user to exercise greater control over the pencil and writing activity. Conversely, if a pencil user attempts to write by grasping the eraser end of the pencil without resting their hand on a stabilizing surface, the writing activity becomes substantially more difficult.
A compact, ergonomic handle may enable a user to rest their hand on a stabilizing surface while still manipulating the handle of the product. This posture is made possible by the short distance between the handle and the surface that is being contacted by the end of the product. Conversely, a long handle creates a greater distance between the hand and the end of the product that the user is manipulating. This greater distance sometimes prevents the user from stabilizing their hand on the surface that is being worked upon. In some cases, this greater distance prevents the user from achieving maximum comfort, control and precision with the product. Thus, the need exists for a product with an ergonomic handle that enables a user to stabilize their hand on a working surface while simultaneously manipulating the handle with that same hand.
The overall shape of the human hand may be described as a rather flat series of structures. In the resting position, the bones of the palm, fingers and thumb are generally structured in the same directional alignment within the same geometric plane. In some cases, it may be beneficial to utilize a handle that more closely matches the resting shape and structure of the human hand. Yet most long, slender, cylindrical handles require the user to bend and curl their thumb and digits around the circumference of the handle.
Similarly, short, round, knob-like handles also require the user to wrap or curl their thumb and digits around the handle. Long, slender handles and short, knob-like handles require the user to squeeze and maintain pressure around the handle. Many of these types of handles require the user to clench their hand, which can be an uncomfortable and even painful activity for some users. Some users with arthritis may find it difficult to curl or wrap their digits around a long handle or a short, knob-like handle. Many users may find it beneficial to grasp an object without being required to substantially bend, curl or wrap their digits around the cylindrical circumference of a common handle. Thus, the need exists for a compact, ergonomic handle that features a broader, yet contoured surface which corresponds to the shape and structure of the human hand at rest. Further, the need exists for an ergonomic handle that enables a user to exert minimal effort when grasping and manipulating the device.
Some tasks require a long handle because the long handle provides the leverage that is necessary to complete the task. In other cases, a long handle may provide the necessary reach or safe distance that is required between the user's hand and the surface that is being contacted. However, some products employ handles that may be unnecessarily long. A more compact, comfortable, ergonomic handle requires less leverage and force that is often required by products with longer handles. Some tasks may be performed more precisely and more efficiently by products that employ a more compact, ergonomic handle. Therefore, the need exists for a compact, ergonomic handle that does not require a user to wrap or curl their thumb and fingers around the circumference of a generally cylindrical, long handle.
Sometimes a long handle may interfere with other objects in the surrounding area. Products with longer handles occupy more space in packaging, on store shelves and in shipping containers. All these factors contribute to a more expensive product. Another shortcoming of long or bulky handles is their inconvenience in portable use. Longer handles also increase the overall weight of a product, thereby adding material cost which creates a higher price point that the consumer is forced to pay. Most handles are designed to be held in one basic position. As a result, many handles restrict the user by limiting the number of ways in which the handle can be gripped and manipulated. Most handles lack a variety of ergonomic options for grasping and manipulating the product. Often, consumers encounter spontaneous circumstances that require product versatility. Therefore, a need exists for a versatile handle that is portable, small, easily usable and affordable. Further, a need exists for a compact ergonomic handle that offers multiple ergonomic options for manipulating a product.
The above discussion is not to be considered exhaustive, however, does demonstrate that a need exists for allowing individuals to efficiently and effectively use compact, ergonomic handle devices. The consuming public is looking for solutions to address these needs and there is an obvious need to fill the gap where the prior art has failed. What is needed is an adaptive device to address these shortcomings in the prior art.
The present embodiments essentially provide a user with a compact, ergonomic handle which may be used in conjunction with other adjoining and complementary shapes, materials, surfaces, textures or tools. More specifically, the ergonomic handle is the basic component that enables other components to be combined with the ergonomic handle or extended from the ergonomic handle. Further, the ergonomic handle is a platform upon which other elements may be implemented. The versatility of the handle and its connected platform allows the handle to be applied to a wide variety of consumer products. The embodiments allow the operator greater comfort, effectiveness and greater portability.
The present embodiments provide a handheld ergonomic handle device comprising a frame having a primary gripping portion that includes a convex portion and a concave portion. In one embodiment, the overall frame of the device includes an underside cavity, a front-end portion, a topside left surface, a topside right surface and a topside front surface, an underside left surface, an underside right surface, an underside front surface, a perimeter edge surface, a front left corner and a front right corner. In another embodiment, the overall frame of the device includes an underside cavity, a front-end portion, a topside left surface, a topside right surface and a topside front surface, an underside left surface, an underside right surface, an underside front surface, a perimeter edge surface. Other embodiments include other combinations of these elements.
The device may be constructed from plastic, polymer, rubber, metal, recycled materials, natural fibers, organic material, wood, etc. The device may be manufactured from a variety of processes, including plastic injection molding, vacuum forming, stamping, pressing, stamping, casting, machining, etc. The device may be constructed from one material or a combination of materials. The device may be rigid, soft or flexible in nature. The device may be constructed from a combination of materials that provide it with both rigid and flexible qualities. The device may be constructed from certain materials that enable it to be folded. For example, the device may be constructed from natural fibers or paper-like substances that enable the device to be bent, folded or creased.
The embodiments may be adapted to perform many diverse tasks. For example, the compact, ergonomic handle may be adapted to perform scrubbing, scraping and cleaning activities. The ergonomic curvature of the handle inherently offers multiple surface areas that may be utilized for various scrubbing, scraping and cleaning activities. These surface areas may be utilized to interact with the surfaces of other objects such as dishes, plates, pots and pans.
Most scrubbing devices utilize bristles, brushes or spongy, absorbent materials that can be squeezed and flexed, thereby conforming to various contoured surfaces. Many of these devices are porous and absorbent, thereby causing the retention of water, moisture, food particles or other debris. Bristles and porous, absorbent materials can create environments where water, moisture and debris particles may linger, which creates an environment that may propagate germs and bacteria. Therefore, a need exists for a three-dimensional, ergonomic, contoured device that can scrub, scrape, scour, scoop and squeegee, yet accomplishes these tasks without bristles or some other absorbent, porous surface. However, the embodiments do not require materials that absorb and retain moisture and other particles.
Some dish cleaning devices are flat in shape. Some of these devices are similar to a flat scraping tool or flat squeegee device whose primary shape is constructed in a single flat plane. They come in square, rectangular, circular, oval, geometric or other irregular shapes. These flat objects often have flat edges and sometimes rounded corners that are designed to allow the user to scrape the surface of a dish. However, these flat objects are limited in their ability to quickly and efficiently clean, scrape or scrub the complex curves and contours of different types of dishes, bowls, forks, spoons, spatulas or other various cleaning utensils. These devices are limited due to the singular plane in which the device is constructed. These devices lack three-dimensionally curved surfaces that would enable the device to more efficiently and effectively reach all the curves and corners of a plate, dish, utensil or other curved object. Therefore, a need exists for an ergonomic handle scrubbing device that employs three dimensional contours.
