The invention relates to a portable and manual clothes wringing system that utilizes a wringer roll apparatus configured to retain wet clothes in a rolled up wringer fabric and having loops extending from the ends to receive rods for twisting and wringing water from the wet clothes.
There are many situations where a person may want to dry or wring out their clothes but do not have access to a clothes dryer, such as when they are camping, or before heading home from the beach or pool. Backpackers and campers often wash their clothes and then hand wring them out and lay them out on a rock or hang them from tree to dry in the sun. Hand wringing has limited effectiveness and the clothes may stay wet which increases their weight, which is not desirable for backpacking. Also, when leaving the beach or a pool, people often change out of their wet bathing suits but they remain very wet which is not desirable.
The invention is directed to a portable and manual clothes wringing system that utilizes a wringer roll apparatus configured to retain wet clothes in a rolled up wringer fabric and having loops extending from the ends to receive rods for twisting and wringing water from wet clothes. The invention is further to a method of wringing water from clothes using the wringer roll apparatus.
The wringer roll apparatus has a wringer fabric that is configured to be rolled around the garments to be wrung out. The wringer fabric may be a microcloth made of microfibers that may be a synthetic material such as, but not limited to, polyesters, polyamides, polypropylene, and combinations thereof. The microfibers may be less than about 1 denier and have a diameter of less than about 10 micrometers. The microfibers of microcloths may have ends that extend away from the microcloth. The ends of the microfibers may be split to form split ends of the microfibers. The split ends of each end of each microfiber may extend in a different direction. The split ends of the microfibers allow microcloth to attract moisture, and thereby allow microcloth to dry wet articles with which they come in contact.
The microcloth may be a suede microcloth or microsuede that includes a particular arrangement of microfiber. Microsuede is a manufactured fabric that may include polyester microfibers. Microsuede is cheaper than genuine suede and is more resistant to wear and stains. Microsuede is extremely durable and long lasting and is lightweight, highly absorbent and quick drying. Microsuede is soft like natural suede leather, resistant to wear, friendly to pets, mostly impervious to stains, easy to care for and inexpensive.
The microfibers of the wringer fabric may be made of polyester, polyamide, or a combination thereof. The wringer fabric may be about 75% or more polyamide and about 25% polyester or less, or any combination of percentages of polyamide and polyester between and including the percentages provided. For example, anywhere from 75% to 85% of the microfibers of the wringer fabric by weight may be polyamide, and 15% to 25% of the microfibers of the wringer fabric by weight may be polyester. Polyester and polyamide are chosen as materials for the microfibers of the wringer fabric since these two materials, when used in microfibers that are formed into a microcloth, allow for a microcloth that is porous and dries quickly. Polyester allows the wringer fabric to retain a structure such as a rectangle. Polyamide fibers are effective to enable the microcloth to absorb more water.
The wringer fabric extends from a first end to a second end, and has a length axis extending from the first end to the second end. The wringer fabric has a first side, a second side, an inside surface, and an outside surface. The wringer fabric may consist of a single layer of fabric which may be a microcloth, such as a microsuede. The wringer fabric may be a rectangle in shape, wherein the first side and second side are substantially parallel to each other and the first end and second end are substantially perpendicular to the sides and substantially parallel with each other. “Substantially parallel” means parallel within about 10 degrees of parallel. “Substantially perpendicular” means perpendicular within about 10 degrees of perpendicular.
The wring fabric may have a length from a first end to a second end of about 0.5 m or more, about 0.75 m or more, about 1 m or more, about 1.25 m or more, about 1.5 m or more and any range between and including the length values provided. The width of the wringer fabric from a first side to a second side may be about 0.5 m or more, about 0.75 m or more, about 1 m or more, about 1.25 m or more, about 1.5 m or more and any range between and including the width values provided. The length may be greater than the width, such as about 1.25 times the width or more, or about 1.5 times the width or more, or even about 2.0 times the width or more. The length may be such that a single person can operate the wringer roll apparatus by standing on an end rod and twisting, by hand, the opposing end rod on the opposing end of the wringer roll.
The wringer roll apparatus may have first end loops extending from the first end and second end loops extending from the second end. Each of the first end and second end may have a plurality of loops such as two or more, three or more, four or more, five or more, six or more, and any range between and including the values provided. A greater number of first end loops and second end loops may enable more uniform distribution of forces during the wringing process. A fewer number of first end loops and second end loops allows for the wringer apparatus to be easier to operate and use as there would be less loops to extend the end rods therethrough and would also make manufacturing less complicated and lower cost.
Wet clothes may be configured to contact the inside surface of the wringer fabric. “Wet clothes” means that the clothes contain a concentration by weight of water that is greater than the weight of the clothes when dry. Dry clothes may be defined as clothes that have less than 5% moisture by weight. A wet article of clothing may have about 10% water by weight or more, about 20% water by weight or more, about 50% by weight of water or more, or as described above about 100% water by weight or more. For example, in an exemplary embodiment, a shirt that weighs 90 g may be considered “wet” if at least 90 g of water is held within the fabric of the shirt, meaning that the 90 g shirt weighs at least 180 g when wet. An article of clothing may be saturated with water, meaning that the fabric of the article of clothing is holding substantially a maximum amount of water for that fabric, or within about 10% of the maximum. For example, cotton may hold up to 25 times its own weight in water. Therefore, a 90 g cotton shirt may hold a maximum of 2.25 kg of water, making the total weight of the saturated shirt 2.34 kg. Saturated is a subset of wet. Therefore, an article of clothing that is saturated may also be considered wet. However, an article of clothing that is considered wet may not be considered saturated unless that article of clothing is holding substantially the maximum amount of water as described herein.
The wringer roll apparatus may be configured to roll around wet clothes to create a wringer roll. The wet clothes may be configured on the wringer fabric and then rolled up within the wringer fabric to form a wringer roll for squeezing or wringing water from the clothes. The clothes may be positioned on the wringer roll fabric such that they create a uniform distribution along the length of the wringer roll when rolled up. Uniformly distributing the clothes may prevent bulging of the clothes in one location and more effectively wring water from the clothes when the wringer roll is twisted. The wringer fabric may be rolled from the first side to the second side to form the wringer roll.
A first end rod may be configured through the first end loops and a second end rod may then be configured through the second end loops of the wringer roll to produce the wringer roll apparatus. The first end rod and second end rod may be solid rods or may be tubes or hollow. An exemplary end rod has a circular cross section, having a smooth rounded exterior that will facilitate sliding the end rod through the end loops. The first end rod and second end rods may be made out of metal or a plastic, such as a rigid plastic including acrylic, polyester, or polyvinyl chloride (PVC). Polyvinyl chloride tubing is commonly used for plumbing applications and is rigid and lightweight. The end rods may have an outside diameter of about 10 mm or more, about 14 mm or more, about 20 mm or more, about 30 mm or more and any range between and including the values provided. The length of the end rod may be about 0.25 m or more, about 0.5 m or more, about 0.75 m or more, about 1 m or more and any range between and including the length values provided. A longer end rod will make it easier to twist as the torque arm is longer, however, if too long, the length may make twisting or rotation difficult, especially for single person operation.
First end sleeves may be configured over ends of the first end rod to provide handles for someone to manually hold onto when twisting the first end rod. Second end sleeves may be configured over ends of the second end rod to provide handles for someone to manually hold onto when twisting the second end rod. The first end sleeves and second end sleeves may be made of a plastic or elastomeric material such as silicone or urethane to provide some comfort during the wringing process and to provide a more secure gripping surface. The first end sleeves and second end sleeves, or one of them may be detachably attachable to the respective end rod to enable easier insertion of the end rods through the respective end rod sleeves. The end rod sleeves may be larger in diameter than the end rod and removing one of them may facilitate threading this end, with the end rod sleeve removed, through the end rod sleeves.
The wringer roll apparatus may then be twisted by twisting the first end rod about the length axis while retaining the second end rod in a fixed position or by turning the second end rod in an opposing direction to the first end rod. This wringing process wrings out water from the wet clothes and water from the wet clothes will flow through the wringer fabric and out of the wringer fabric. The wringer roll apparatus may be operated by a single person, wherein a first end is retained in a fixed position by standing on the first end rod and twisting the second end rod that is configured through the second end loops on the second end of the wringer roll. In this method, the wringer roll extends vertically up in front of a person. Also, the wringer roll apparatus may be operated by two people, wherein a first person twists a first end rod extending through the first end loops of a wringer roll and wherein a second person holds onto the second end rod. The second person may secure the second end rod and prevent it from twisting due to the force created by the first person, or may rotate the second end rod in a direction opposite to the rotational direction of the first end rod rotation. This counter rotating end twisting may provide increased force and more effectively wring water from the clothes within the wringer roll.
Water is squeezed out of the clothes during the wringing process and may absorb into the wringer fabric and then drip or flow out of the wringer fabric to dry the clothes. Also, water may be absorbed by the wringer fabric to effectively dry the clothes.
The clothes may be considered dried clothes when an effective amount of water is removed from the clothes, such as about 30% or more, about 50% or more, about 75% or more, about 80% or more, or even about 90% or more. Some types of fabrics may more readily enable water to be wrung from them and removed using the wringer roll apparatus.
When the wringer roll apparatus is twisted the inside surface and outside surface of the wringer fabric press against the wet clothes to squeeze and compress water from the clothes. The split ends of the microfibers of the wringer fabric may attract water from the wet clothes to enable the water to flow through the wringer fabric, where it is expelled from the wringer roll. When the wringer roll apparatus is twisted, the microfibers of the wringer fabric may be configured closer together, and may exert forces on each other that push the water that was absorbed by the wringer fabric out of the wringer fabric. In this manner, the wringer roll apparatus, may “wring” water from clothes by exerting a physical force to force water out of the fabric of the clothes, attracting the water using microfibers of the microcloth, and exerting forces on the microfibers of the microcloth to force the water out of the microcloth and out of the wringer apparatus, thereby removing water from the clothes and expelling the water outside of the wringer roll.
The wringer roll apparatus may be capable of drying a variety of fabrics. The chart below shows a study that was performed on the wringer roll apparatus wherein the wringer roll apparatus and a washing machine powered by electricity and using a spin cycle were each used to dry various clothing items. The clothing items were saturated with water prior to being dried by the wringer roll apparatus and the washing machine. The clothing items were each dried by the wringer roll apparatus and the washing machine separately, allowing for a comparison in the drying ability of the wringer roll apparatus and the washing machine. As shown in the chart, the washing machine is more effective than the wringer roll apparatus at drying clothes, with the exception of drying 100% cotton towels. However, the wringer roll apparatus does dry every clothing item of the study by removing at least 30% of the water weight added to saturated clothing items.
The wringer fabric of the wringer roll used in this study was a micro-cloth made of microfiber having an 80% polyester and 20% polyamide blend. The washing machine used was a Bubble Wash 8.5 kg, Digital Inverter Technology, Model #WW85H5400EW.
The wringer roll apparatus has a number of advantages over a washing machine. The wringer roll apparatus is more cost-effective that a washing machine. Also, the wringer roll apparatus does not require an electrical power source and is manually operated. The wringer roll apparatus is portable and can be easily taken with a person on a trip, to a pool or body or water or into remote areas such as when camping or backpacking. A portable wringer roll apparatus is portable in that it can be easily carried by a single person and may weigh about 10 kg or less, about 8 kg or less, about 5 kg or less or even 3 kg or less, and any range between and including the weights provided.
The invention is further directed to a method of wringing water from wet clothes. The clothes wringing system described herein may be provided. Wet clothes may be provided, and may be configured on the wringer fabric. The wet clothes may be configured on the inside surface of the wringer fabric. The clothes may be uniformly distributed along the wringer fabric, wherein the total thickness of the combined clothes may be substantially uniform across the area of the wringer fabric.
The wringer fabric may be rolled from the first side to the second side to produce a wringer roll and to retain the clothes within the wringer roll. The clothes may contact both the inside surface and the outside surface of the wringer fabric when retained within the wringer roll. The first end rod may be configured through the first end loops, and the second end rod may be configured through the second end loops.
The second end rod may be retained in a stationary position, and the first end rod may be twisted relative to the second end rod. The first end rod may be twisted about the length axis. The first end rod may be twisted one or more revolutions about the length axis, such as about 3 or more rotations about five or more rotations. The more rotations increases the compression force on the wringer fabric and the wet clothes retained therein. The twisting of the first end rod relative to the second end rod may cause the wringer roll to twist about the length axis, thereby wringing water from the wet clothes, thereby drying the clothes. The second end rod may be retained in a stationary position by a first user standing on the second end rod. The first end rod may be twisted by hand by the first user, while the first user stands on the second end rod. In this way, the wringer roll apparatus may be operated by a single person to wring water out of wet clothes. Alternatively, the first user may twist the first end rod by hand while a second user holds the second end rod to retain the second end rod in a stationary position. Alternatively, the second user may twist the second end rod relative to the first end rod in a direction opposite to the direction in which the first end rod is twisted.
The first end rod may then be twisted in an opposite direction relative to the second end rod to untwist the wringer roll. The wringer roll may be unrolled by rolling the first side away from the second side to release the dry clothes from the wringer roll.
