This disclosure relates to umbrellas and, in particular, to hand-held motorized umbrellas.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Umbrellas are well known devices in many areas of the world. However, the vast majority of hand-held umbrellas operate manually, through user movement of a runner to open, close, or latch the canopy, or semi-automatically, by triggering a mechanical device such as a spring to open, close, or latch the canopy. In particular manual umbrellas can be inconvenient and even messy to close after rain has soaked the canopy. Therefore, a hand-held umbrella which may be motorized to fully automatically open and close automatically is desirable.
Additionally, because holding an umbrella requires the use of one hand, users of umbrellas are frequently hindered in the use of their other hand. For example, while using an umbrella, they cannot hold another object and answer an incoming call with their phone at the same time. Even if the phone is operated with headphones, the user must still take headphones from a pocket or case, place them on their ear, and then pair them to the phone before being operative. Such steps may require one or both hands, causing inconvenience for the user of the umbrella, especially in heavy rain. Therefore, an umbrella which can easily be paired to a phone, which can be used as a speaker and microphone for a phone, and which can be opened and closed with just one hand is desirable.
Moreover, hand-held umbrellas are frequently difficult to manufacture, requiring multiple tools and multiple processes. For example, even after all components have been gathered, assembly of the umbrella may require riveting components of the rib together, stitching the canopy to the folding mechanism of the umbrella, loading a spring mechanism, and screwing other components of the umbrella together. Multiple tools and multiple processes drives up the cost of umbrella assembly. Therefore, an umbrella which is easy to assemble with a single tool and a single process is desirable.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

The hub 12 may be any portion of the umbrella 11 which forms the center of the canopy (72 in
The plurality of arms 14 may be rotatably coupled to the hub 12 at a plurality of first joints 24. Each of the first joints 24 may be located at an interior end of the arm 14. The arms 14 may be any component of the umbrella 11 which extend from the hub 12 to at least partially define the shape of the umbrella 11. Examples of the arms may include poles, rods, or limbs. The first joints 24 between the arms 14 and the hub 12 may allow the arms to rotate between an open first position and a closed second position. Each of the arms 14 may also include an end cavity 40 adapted to receive a rib (18 in
The plurality of stretchers 16 may be rotatably coupled to each of the arms 14 at the receptables 42 of the arms 14 at exterior ends of the stretchers 16. The stretchers 16 may be any component of the umbrella 11 which is coupled to one the arms 14 and which provides support for one of the arms 14 while the umbrella 11 is in the first open position (as shown in
The runner 20 may be rotatably coupled to each of the plurality of stretchers 16 at a plurality of second joints 26. Each of the plurality of second joints 26 is arranged at an interior end of the stretcher 16. The runner 20 may be any component of the umbrella 11 which is moveable along a single axis to allow the umbrella 11 to reversibly move from the first open position to the second closed position. Examples of the runner 20 may include a piston, a cylinder, or a pole. The runner 20 may include a shaped sleeve 44 situated on the outer surface of the runner 20.
In some embodiments, the runner 20 may have an upper portion which is separable from a lower portion of the runner 20. The stretchers 16 may be arranged between the upper portion and the lower portion to form second joints 26. Screws may be used to secure the upper portion to the lower portion of the runner 20.
The runner 20 may be coupled to a motor 22 to reversibly move the runner 20 from a first position to a second position. When the runner 20 is in the first position (as in
The motor 22 may be encased within the shaft 62. The shaft 62 may be any portion of the umbrella 11 which is elongated and allows the user to maintain a position of the umbrella 11 while it is in the open position. Examples of the shaft 62 may include an elongated cylinder, a tube, or a pole. The shaft 62 may be made of any material sufficient for maintaining the position of the umbrella 11 while in the open position, such as aluminum, plastic, or carbon fiber.
In some embodiments, the shaft 62 may divided into an upper portion (as shown in
While the folding mechanism 10 is in the open position, the runner 20 may be positioned beneath the bottom 30 of the hub 12. While the runner 20 is in the first position, the first joints 24 between the hub 12 and the arms 14 may be arranged to be closer to the top 28 of the hub 12 than the second joints 26 between the runner 20 and the stretchers 16. While the runner 20 is in the first position, the open distance 52 of the first joints 24 from the second joints 26 relative to the top 28 of the hub 12 may be between 1.50 and 4.60 centimeters, but preferably about 2.39 centimeters.
As illustrated in
While the folding mechanism is in the closed position, the runner 20 may be in the second position, advanced along the spindle 46 by the motor 22 an advancement distance 56 of between 2 and 6 centimeters, but preferably about 3.09 centimeters. In some embodiments, the sleeve 44 may also be advanced along the spindle 46. In the second position, runner 20 may be at least partially advanced into the hub cavity 32 such that the interior hub projection 36 may be inserted into the seat 38 of the runner 20. The outer surface of the sleeve 44 may be shaped to closely receive the stretchers 16 while the folding mechanism 10 is in the closed position, constraining the motion of the arms 14 and stretchers 16 while the umbrella 11 is closed.
While the folding mechanism 10 is in the closed position, the second joints 26 may be arranged within the hub cavity 32. Therefore, in such a configuration, the second joints 26 may be arranged to be at least as close to the top 28 of the hub 12 than the first joints 24. In some embodiments, the second joints 26 may be arranged to be closer to the top 28 of the hub 12 than the first joints 24. While the runner 20 is in the second position, the closed distance 54 of the first joints 24 from the second joints 26 relative to the top 28 of the hub 12 may be between 0.50 and 1.40 centimeters, but preferably about 0.70 centimeters. In some embodiments, the sum of the open distance 52 and the closed distance 54 may be equal to the advancement distance 56 of the runner 20 from the first position to the second position.
As illustrated in
As illustrated in
The umbrella 11 may also include a hub cap 58 which may be inserted onto the upper projection 34 of the hub 12. To accommodate and secure the hub cap 58, the upper projection 34 may be threaded such that the hub cap 58 may be screwed onto the upper projection 34.
The hub 12 may include an outer surface 64 which is shaped to limit the rotation of the arms 14 within the first joints 24. For example, as illustrated in
In some embodiments, the struts 60, as illustrated in
The canopy 72 may further include a plurality of canopy sleeves 74, wherein each canopy sleeve 74 may be configured to receive an exterior end of a rib 18. The canopy sleeves 74 may be sown into the under side of the canopy 72 such that they may not be visible from the top of the canopy 72. Furthermore, the canopy sleeves 74 may be sized between 2 and 20 centimeters in length to sufficiently secure the ribs 18 within the canopy sleeves 74, but also allow the ribs 18 from the canopy sleeves 74 to be manually removed by a user replacing the canopy.
The ribs 18 may be any component of the umbrella 11 which extends outwardly from one of the arms 14. Examples of the ribs 18 may include a pole, a rod, or a wire. The ribs 18 may include an interior end arranged within the end cavity 40 of the arms 14 and an exterior end extended outwardly and opposite from interior end. Each of the ribs 18 may be friction-fitted into one of the end cavities 40 such that the ribs are held in place between the end cavities 40 and the canopy sleeves 74. The ribs 18 may be made of a strong but flexible material such as aluminum, steel alloys, wood, bamboo, or carbon fiber. The ribs 18 may be somewhat flexible to allow some movement in the canopy 72. This flexibility makes the canopy 72 easer to be manually removed by the user and makes the umbrella 11 easier to hold by the user during high winds. Each of the arms 14 may be more rigid than each of the ribs 18 to enhance the overall stability of the umbrella 11 and to prevent the umbrella 11 from inverting in high winds.
Allowing flexibility and maintaining stability of the umbrella 11 may also be governed by the relative lengths of the arms 14 as they extend outwardly from the hub 12 and of the ribs 18 as they extend outwardly from the arms 14. For example, if the ribs 18 are too long relative to the arms 14, the umbrella 11 may effectively be inverted in high winds even with the added stability of the arms 14. Alternatively, if the ribs 18 are too short relative to the arms 14, the umbrella 11 may be too rigid and inflexible to be easily held in high winds. Furthermore, in such a configuration, the canopy 72 may be too securely attached to the umbrella 11 such that it cannot be manually removed and replaced. For at least these reasons, the lengths 75 of the arms 14 should be between 10 and 20 centimeters. Additionally, the lengths 77 of the ribs 18 should be between 30 and 60 centimeters. Even if the umbrella 11 was scaled up or down from these lengths 75, 77, a ratio between the lengths 75 of the ribs 18 and the lengths of the arms 14 should be between 1.5 and 3.0, but preferably about 2.0.
The electrical energy source 84 may be any component of the umbrella 11 which provides electrical energy to operate the motor 22 and any other electrically operated devices within the umbrella 11. Examples of the electrical energy source 84 may include a battery or a connection to an alternating current (AC) power source. In some embodiments, the electrical energy source 84 is capable of providing electrical power at a voltage of between 3.0 and 3.7 Volts to allow for a smaller and lighter electrical energy source 84Soi. The electrical energy source 84 may be charged through an electrical port 86 defined on the outer surface of the shaft 62. Examples of the electrical port 86 may include a universal serial bus (USB) port, a 2-pole outlet plug, or a direct current (DC) power cable.
A control system 90 may also be embedded within the shaft 62. The control system 90 may be any component which may operate any electrically operated devices in the umbrella 11. For example, the control system 90 may be in electrical communication with the motor 22 and the electrical energy source to selectively operate the motor 22 according to a user input. The control system 90 may include a switch 82 which is accessible from the outer surface of the shaft 62 manipulate the control system 90 to operate the motor 22. Examples of the switch 82 may include a button, a slider, or a toggle switch.
In some embodiments, the control system 90 may include a transmitter/receiver, such as a Bluetooth® short-range wireless device. Such a transmitter receiver may allow the control system 90 to integrate with and be operated by an external device, such as a phone. Furthermore, such embodiments of the umbrella 11 may include the microphone 92 and the speaker 94 embedded within the shaft 62. A microphone opening 96 and also one or more speaker openings 98 may be defined on the outer surface of the shaft 62 to allow audio communication between a user and the speaker 94 and microphone 92.
A user may connect their phone to the control system 90 of the umbrella 11 to use the microphone 92 and speaker 94 as an alternative phone audio system. As a result, the user may not need to use a hand to operate the phone, allowing them to maintain control of the umbrella 11 with at least one hand.
In some embodiments all electrical components of the umbrella 11 may be manipulated by a single switch 82 accessible from the outer surface. For example, a quick press of the switch 82 may open the umbrella 11 and a second quick press of the switch 82 may close the umbrella 11. Furthermore, the phone may be at least partially controlled by the single switch 82. For example, a long press of over 3 seconds may connect and disconnect the phone from the control system 90. While a phone is connected, two quick presses of the switch 82 may answer an incoming call or end a call. Furthermore, tilting the switch 82 upward or downward may raise or lower the volume of the speaker 94.
In another embodiment, a power toggle (not shown) may be included on the outer surface of the shaft to electrically connect the electrical energy source 84 to the other electrically operated components of the umbrella 11. In such an embodiment, when the power toggle is in the “on” position, all electrical components of the umbrella 11 may be manipulated by the single switch 82. When the power toggle is in the “off” position, the electrical components of the umbrella 11 may be inoperative. In such an embodiment, the power toggle may not operate any electrically operated components of the umbrella 11, but merely allows the single switch 82 to operate the electrically operated components. In some embodiments, the power toggle may be incorporated into the single switch 82. For example, the single switch 82 may slide from a first unpowered, inoperable position into a second position. In the second position, the electrically operated components of the umbrella 11 may be powered and operable by the single switch 82.
Furthermore, although specific components are described above, methods, systems, and articles of manufacture described herein may include additional, fewer, or different components. For example, additional electrical components could be incorporated into the umbrella 11 to be operated by the control system 90. In one embodiment a small fan could be incorporated into the shaft 62 or folding mechanism 10 to circulate air within the canopy 72 while the umbrella 11 is open.
The umbrella 11 may be formed in a manufacturing process 100. The plurality of arms 14 may be coupled to the hub 12 (102). Each of the plurality of stretchers 16 may be coupled to one of the arms 14 (104). The plurality of stretchers 16 may also be coupled to the runner 20 (108). Each of a plurality of ribs 18 may be coupled to one of the arms 14 (106). The runner 20 may be coupled to the motor 22 (110). The runner 20 may be moveable from a first position to a second position such that lowering the runner 20 away from the hub 12 from the first position to the second position opens the umbrella 11. Conversely, raising the runner 20 toward the hub 12 from the second position to the first position closes the umbrella 11.
In some embodiments, some or all of the manufacturing process 100 described above may be performed using only a single tool or a single process. For example, as discussed above, the arms 12 may be coupled to the hub 12 (102) using screws extending between the hub 12 and the struts 60. The screws may be inserted into the hub 12 by use of a screwdriver. The stretchers 16 may be coupled to the arms 14 (104) by a receptacle 42 in the form of a snap joint, requiring only manual insertion by hand. Similarly, the ribs 18 may be manually inserted into the end cavities 40 of the arms 14 (106) and held in place by friction fitting. The stretchers 16 may be coupled to the runner 20 (108) by an upper portion of the runner 20 being screwed onto a lower portion of the runner 20 by hand or by use of a screwdriver. The runner 20 may be screwed onto the spindle 46 of the motor 22 (110) by hand or by use of a screwdriver. As a result of this method, the umbrella 11 may be manufactured using only a screwdriver or through manual hand operation, significantly simplifying and decreasing the cost of the manufacturing process
In addition to the advantages that have been described, it is also possible that there are still other advantages that are not currently recognized but which may become apparent at a later time. While various embodiments have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible. Accordingly, the embodiments described herein are examples, not the only possible embodiments and implementations.
