A person can use a variety of different devices with electrical cords. Example devices include power tools, kitchen appliances, and hair-care equipment (e.g., blow dryers, curling irons, or flat irons). In addition to being disorderly, unwound electrical cords can present a safety hazard. A person may accidentally come in contact with the cord and cause the attached device to drop onto the floor. Or a child may be able to pull on the cord to access and operate the device. In some cases, substances can be accidentally spilled onto the cords and result in unsanitary conditions, especially in medical facilities.
Techniques and apparatuses are described that implement a coiler. The coiler can compactly organize a variety of flexible elements while enabling one portion of a flexible element to remain at a fixed position. In this way, the flexible element can be directly connected to a stationary source while the coiler winds and unwinds the flexible element. This makes it convenient for users to readily use the flexible element.
Instead of using a rotating reel, the coiler includes a rotating member and a stationary shaft. The rotating member rotates and passes the flexible element to the shaft. In this manner, the rotating member mimics the action of a person manually coiling the flexible element onto the shaft. Because the shaft remains relatively stationary as the flexible element is coiled or uncoiled, the coiled portion of the flexible element also remains relatively stationary. Consequently, the coiler can forego other complicated or expensive interfaces and enable the flexible element to connect directly to the stationary source.
Aspects described below include a coiler. The coiler includes a fixed member, a shaft, a rotating member, and a rotation mechanism. The fixed member includes an insertion slot configured to secure a first portion of a flexible element. The shaft has first and second ends. The first end is positioned proximate to the fixed member. The rotating member is positioned proximate to the second end of the shaft and is configured to rotatably move about an axis of rotation. The rotating member includes a guide, which is offset from the axis of rotation. The guide is configured to enable a second portion of the flexible element to pass through the rotating member. The rotation mechanism is configured to rotate the rotating member in a first direction around the axis of rotation to coil the second portion of the flexible element around the shaft.
Aspects described below include an apparatus. The apparatus includes a shaft. The apparatus also includes fixed means for securing a first portion of a flexible element. The apparatus additionally includes rotating means for coiling a second portion of the flexible element around the shaft as the shaft as the shaft and the fixed means remain relatively stationary compared to the rotating means.
Aspects described below include a system. The system includes at least one flexible element and a coiler.
Aspects described below also include a method performed by a coiler. The method includes securing a first portion of a flexible element to a fixed member of the coiler. The method also includes rotating a rotating member of the coiler in a first direction around an axis of rotation as the fixed member and a shaft of the coiler remain relatively stationary. The shaft is positioned between the fixed member and the rotating member. The method additionally includes passing a second portion of the flexible element through the rotating member. The method further includes coiling the second portion of the flexible element around the shaft.
Apparatuses for and techniques implementing a coiler are described with reference to the following drawings. The same numbers are used throughout the drawings to reference like features and components:
A person can use a variety of different devices with electrical cords. Example devices include power tools, kitchen appliances, and hair-care equipment (e.g., blow dryers, curling irons, or flat irons). In addition to being disorderly, unwound electrical cords can present a safety hazard. A person may accidentally come in contact with the cord and cause the attached device to drop onto the floor. Or a child may be able to pull on the cord to access and operate the device. In some cases, substances can be accidentally spilled onto the cords and result in unsanitary conditions, especially in medical facilities.
To address this problem, some techniques use a winding system. The winding system spins a reel to wind or unwind a given material, such as an electrical cord or a water hose. A portion of the material that is unwound is aligned approximately parallel to the direction of rotation. As the reel spins, the coiled material spins, which makes it complicated to attach the coiled material to a stationary source, such as an electrical outlet or a water spigot.
To enable the material to be operably coupled to a stationary source, some winding systems include an interface. The interface enables the material to be “indirectly” connected to the stationary source while the material rotates around the reel. One such interface includes a wiper system. The wiper system enables an electrical cord that is wound around the reel to be connected to an electrical outlet. In particular, the wiper system includes internal wiring, which connects the electrical contacts of the electrical cord on the rotating reel to an intermediate electrical cord that connects to the power source. In addition to increasing a cost and complexity of the winding system, the wiper system may have voltage or amperage limitations. As such, the wiper system may not support some electrically-powered devices. If the user is unaware of these limitations, the user may accidentally use the winding system on a device that is not supported by the wiper system. Consequently, the mismatch between the electrical device and the wiper system can damage the electrical device, damage the wiper system, or potentially start a fire.
In contrast, this document describes techniques and devices that implement a coiler. The coiler can compactly organize a variety of flexible elements while enabling one portion of a flexible element to remain at a fixed position. In this way, the flexible element can be “directly” connected to a stationary source (e.g., without an interface such as the wiper system) while the coiler winds and unwinds the flexible element. This makes it convenient for users to readily use the flexible element.
Instead of using a rotating reel, the coiler includes a rotating member and a stationary shaft. The rotating member rotates and passes the flexible element to the shaft. In this manner, the rotating member mimics the action of a person manually coiling the flexible element onto the shaft. Because the shaft remains relatively stationary as the flexible element is coiled or uncoiled, the coiled portion of the flexible element also remains relatively stationary. Consequently, the coiler can forego other complicated or expensive interfaces and enable the flexible element to connect directly to the stationary source.
To address these problems, the coiler 102 can coil and uncoil the electrical cord 106 while enabling the electrical cord 106 to be attached to the electrical outlet 108. In this way, the coiler 102 can neatly organize the electrical cord 106 within a small area and keep the electrical cord 106 out of the way of small children or accidental spills when the hair dryer 104 is not in use. In some implementations, the coiler 102 can include a stand to store the hair dryer 104. The coiler 102 can coil and uncoil a variety of different materials. As such, the coiler 102 has many applications in a home environment as well as a variety of different industries, as further described with respect to
In general, the flexible element 204 includes two ends. A first end of the flexible element 204 can be connected to a source or a fixed point. Example sources can include a power source (e.g., the electrical outlet 108), a water source (e.g., a water spigot), or a storage tank containing liquid or gas. A second end of the flexible element 204 can be connected to the device 202. In some devices 202, the second end is attached to or integrated within the device 202. In other devices 202, the second end can be optionally removed or disconnected from the device 202. The flexible element 204 can allow particles to flow from the source to the device 202. For example, the flexible element 204 can allow electrical current or fluid (in liquid or gas form) to flow from the source to the device 202. The flow of particles provided by the flexible element 204 can enable the device 202 to operate.
The coiler 102 can coil (e.g., wind or wrap) the flexible element 204 for convenient storage or uncoil (e.g., unwind or unwrap) the flexible element 204 to enable a user to operate the device 202. The coiler 102 enables the device 202 to operate while the flexible element 204 is in a coiled state, an uncoiled state, or a partially-coiled state.
The device 202 can include a variety of different electrical devices. In this case, the flexible element 204 includes the electrical cord 106. Example electrical devices 202 can include hair equipment, such as the hair dryer 104, a curling iron 202-1, or a flat iron 202-2. As another example, the device 202 can include a kitchen appliance 202-3, such as a mixer, a toaster, or a food processor. The device 202 can alternatively be a power tool 202-4, such as a corded drill or an angle grinder. Other types of electrical devices 202 include computing devices 202-5 or medical equipment 202-6. Example computing devices 202-5 include a smartphone or a laptop. Example medical equipment 202-6 can include a sensor, such as a heart-monitoring sensor.
Other types of devices 202 use fluids (e.g. liquids or gas). In this case, the flexible element 204 can include the water hose 204-1 or the flexible tubing 204-2. Example fluid-based devices 202 can include medical equipment 202-6 or dental equipment 202-7. The medical equipment 202-6 can include an oxygen mask or an intravenous (IV) system. The dental equipment 202-7, can include a suction device or an ultrasonic scaler. Other types of fluid-based devices 202 include farm equipment 202-8, such as a tank sprayer.
Still other types of devices 202 rely on the tension of the flexible element 204. In this case, the flexible element 204 can include the rope 204-3, the cable 204-4, or the chain 204-5. Example tension-based devices 202 can include climbing equipment 202-9, such as a lifeline, or a winch 202-10.
In general, the coiler 102 can be used interchangeably with a variety of different devices 202, including those with different power requirements. As such, a user can safely use the coiler 102 with the hair dryer 104 or a power tool 202-4. Other systems 200 can include the coiler 102 and the flexible element 204 without including a device 202. For example, the system 200 can include the coiler 102 and the water hose 204-1. The coiler 102 is further described with respect to
The shaft 304 provides a support for the flexible element 204 to coil around. In some aspects, the shaft 304 can have a tapered structure to assist the flexible element 204 in coiling around the shaft 304 in an orderly fashion. A length of the shaft 304 can be designed to fit a particular length of the flexible element 204. A diameter of the shaft 304 can be tailored to enable the flexible element 204 to neatly coil around the shaft 304. Such shaft dimensions (e.g., structure, length, diameter) can be adapted to enable the flexible element 204 to be wound around the shaft 304 in substantially concentric rings. An example design of the shaft 304 is further described with respect to
The rotating member 306 performs the action of coiling and uncoiling the flexible element 204. In some implementations, the rotating member 306 has a circular shape. The rotating member 306 includes a guide 312, which enables the flexible element 204 to pass through the rotating member 306 and presents the flexible element 204 at an approximate 90 degree angle to the direction of rotation. In some cases, the angle is approximately equal to 80, 85, 88, 92, 95, or 100 degrees. In general, the term “approximately” can mean that any of the angles can be within +/−10% of a specified value or less (e.g., within +/−5%, +/−3%, or +/−2% of a specified value). The guide 312 represents an opening, cutout, gap, or hole, which is present within the rotating member 306. In general, a size of the guide 312 is larger than a cross-sectional size (e.g., diameter) of the flexible element 204 to reduce tension or stress on the flexible element 204 as it passes through the rotating member 306. The guide 312 can also include at least one roller, which freely rotates to reduce friction between the guide 312 and the flexible element 204. An example implementation of the roller is further described with respect to
The coiler 102 also includes at least one rotation mechanism 316. The rotation mechanism 316 rotates the rotating member 306. The rotation mechanism 316 can be driven manually or mechanically. In example implementations, the rotation mechanism 316 includes an electric motor, a spring, or a hand crank. The rotation mechanism 316 causes the rotating member 306 to selectively rotate counter-clockwise or clockwise. Accordingly, the rotation mechanism 316 can include an interface enabling the user to specify the direction of rotation. If the rotation mechanism 316 includes an electric motor, the interface can include buttons enabling the user to cause the coiler 102 to coil or uncoil the flexible element 204. The rotation mechanism 316 is further described with respect to
The coiler 102 can optionally include a housing 318. In an example, the housing 318 encloses the fixed member 302, the shaft 304, the rotating member 306, and the rotation mechanism 316. In this way, the housing 318 can protect these components as well as a coiled portion of the flexible element 204 from sun exposure and weather. The housing 318 can optionally include at least one stand 320, which can hold an end of the flexible element 204 or the device 202 that is attached to the flexible element 204. For example, the stand 320 can include an opening for placing the hair dryer 104, the curling iron 202-1, the flat iron 202-2, or the power tool 202-4. In some aspects, the stand 320 can be heat or corrosion resistant.
The fixed member 302, the shaft 304, the rotating member 306, portions of the rotation mechanism 316, and the housing 318 can be built from a variety of different materials, including plastic, metal, wood, or some combination thereof. The coiler 102 is further described with respect to
In
To position the flexible element 204 within the coiler 102, the user opens the cover 402 and places a first section of the flexible element 204 in the insertion slot 308. The insertion slot 308 secures a first portion 404 of the flexible element 204, which prevents the first portion 404 of the flexible element 204 from substantially moving as the coiler 102 operates. Because the insertion slot 308 holds the first portion 404 of the flexible element 204 stationary (or at least stationary relative to the shaft 304), the coiler 102 does not coil the first portion 404 of the flexible element 204 around the shaft 304.
The first portion 404 of the flexible element 204 can include an end (e.g., a first end) of the flexible element 204, which the user may connect to a stationary source, such as an electrical outlet 108 or a water spigot. In general, the first portion 404 of the flexible element 204 includes a portion of the flexible element 204 that exists between the insertion slot 308 and the first end of the flexible element 204, which can be connected to the stationary source or the fixed point. As such, a majority of the first portion 404 is positioned outside of the housing 318.
In some situations, the user can pass a second portion 406 of the flexible element 204 through the guide 312. In general, the second portion 406 of the flexible element 204 includes a portion of the flexible element 204 that is between the insertion slot 308 and an end (e.g., a second end) of the flexible element 204 that is connected to the device 202 or is handled by the user. In contrast to the first portion 404 of the flexible element 204, the coiler 102 can coil the second portion 406 of the flexible element 204 around the shaft 304.
To assist the user in placing the second portion 406 of the flexible element 204 through the guide 312, the front plate 314 can optionally include a removable portion, as further described with respect to
To use the coiler 102, a user activates the rotation mechanism 316, which causes the front plate 314 to rotate in a first direction to coil the flexible element 204. As the front plate 314 rotates, the second portion 406 of the flexible element 204 moves through the guide 312 and coils around the shaft 304. To uncoil the flexible element 204, the user can activate the rotation mechanism 316 to cause the front plate 314 to rotate in a second direction, which is opposite the first direction. As an example, the first direction can be a clockwise direction and the second direction can be a counter-clockwise direction, or vise-versa. In
While the front plate 314 rotates, the back plate 310 and the shaft 304 remain relatively stationary. Consequently, the tension on the flexible element 204 and the rotation of the front plate 314 relative to the stationary back plate 310 causes the flexible element 204 to coil or uncoil. Because the back plate 310 enables the first portion 404 of the flexible element 204 to remain relatively stationary, the flexible element 204 can be directly connected to a stationary source (e.g., the electrical outlet 108 or a water spigot) or a fixed position.
Although not shown in
In an alternative implementation (not shown), the front plate 314 can include a snap closure instead of the removable portion 504. The snap closure can snap in place across the guide 312 or rotatably move (e.g., swing) away via a hinge to allow a user access to the guide 312.
In
In other implementations, the guide 312 can include multiple rollers 506. For example, the guide 312 can include two rollers 506 on opposite sides or four rollers 506 on individual sides. The rollers 506 can be installed within the front plate 314 or as part of the removable portion 504 of the front plate 314. As an example, the removable portion 504 can have two rollers 506 on opposite sides (e.g., one roller 506-1 on the left side and another roller 506-2 on the right side). Additional features of the coiler 102 are further described with respect to
An axis of rotation 602 passes through a center of the front plate 314 and is parallel to the second axis 412. A center of the shaft 304 is positioned on the axis of rotation 602. A planar surface 606 of the front plate 314 and a planar surface 608 of the back plate 310 can be approximately perpendicular to the axis of rotation 602.
As shown in
In the depicted configuration, the shaft 304 includes a first tapered section 702-1 and a second tapered section 702-2. The first tapered section 702-1 is positioned proximate to the back plate 310, and the second tapered section 702-2 is positioned proximate to the front plate 314. The first tapered section 702-1 has a slope with a first angle 704-1 relative to the planar surface 608 of the back plate 310. The second tapered section 702-2 has a slope with a second angle 704-2 relative to the planar surface 608 of the back plate 310. The first angle 704-1 is greater than the second angle 704-2 (e.g., by at least 1, 5, 10, or 15 degrees). As an example, the first angle 704-1 can be approximately 78 degrees, and the second angle 704-2 can be approximately 62 degrees.
If the shaft 304 includes multiple tapered sections 702, the angles of the slopes of the tapered sections 702 can decrease as the tapered sections 702 are positioned closer to the front plate 314. In this way, the shaft 304 has a larger diameter closer to the front plate 314 and a smaller diameter closer to the back plate 310. Components of the rotation mechanism 316 are further described with respect to
The wheel 802 is in contact with an edge of the front plate 314. As the wheel 802 rotates, the wheel 802 causes the front plate 314 to rotate. In some implementations, the front plate 314 and the wheel 802 are implemented as intermeshing gears. Aspects of the rotation of the front plate 314 are further described with respect to
At 904, the front plate 314 rotates clockwise such that the guide 312 moves or revolves towards the right of
At 906, the front plate 314 continues to rotate clockwise such that the guide 312 moves or revolves towards the left of
The tension applied from the insertion slot 308 securing the first portion 404 of the flexible element 204 and the tapered sections 702-1 and 702-2 of the shaft 304 cause the flexible element 204 to form a first coil closer to the back plate 310 compared to the front plate 314. As the front plate 314 rotates, additional coils are formed, as further described with respect to
In this example, the flexible element 204 is coiled three times around the shaft 304 to form coils 1008-1, 1008-2, and 1008-3. Due to the tapered sections 702-1 and 702-2 of the shaft 304, the coils 1008-1 to 1008-3 are arranged in an orderly fashion. In particular, a first coil 1008-1 forms proximate to the back plate 310, a second coil 1008-2 forms between the first coil 1008-1 and the front plate 314, and a third coil 1008-3 forms between the second coil 1008-2 and the front plate 314. Sometimes, the coils 1008-1 to 1008-3 can abut adjacent coils 1008. For example, the coil 1008-2 can abut the coils 1008-1 and 1008-3. Although not explicitly shown, multiple layers of coils 1008 can form as additional portions of the flexible element 204 coil around the shaft 304.
At 1102, a first portion of a flexible element is secured to a fixed member of a coiler. For example, the insertion slot 308 of the fixed member 302 (e.g., the back plate 310) secures the first portion 404 of the flexible element 204 to the fixed member 302, as shown in
At 1104, a rotating member of a coiler is rotated in a first direction around an axis of rotation as the fixed element and a shaft of the coiler remain relatively stationary. The shaft is positioned between the fixed member and the rotating member. For example, the rotation mechanism 316 rotates the rotating member 306 (e.g., the front plate 314) in a first direction around the axis of rotation 602 as the fixed member 302 and the shaft 304 remain relatively stationary compared to the rotating member 306, as shown in
At 1106, a second portion of the flexible element is passed through the rotating member. For example, the guide 312 passes the second portion 406 of the flexible element 204 to through the rotating member 306. In some implementations, the guide 312 can include at least one roller 506 to enable the flexible element 204 to pass through the rotating member 306 with less friction and tension in comparison to a fixed side that the flexible element 204 slidably moves across.
At 1108, the second portion of the flexible element is coiled around the shaft. For example, the coiler 102 coils the second portion 406 of the flexible element 204 around the shaft 304. In some implementations, the shaft 304 can include one or more tapered sections 702 to enable the flexible element 204 to start coiling closer to the back plate 310 than the front plate 314, as shown in
