DETAILED DESCRIPTION OF THE EMBODIMENTS

(21) The figures and the following description illustrate specific exemplary embodiments of the invention. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the invention and are included within the scope of the invention. Furthermore, any examples described herein are intended to aid in understanding the principles of the invention and are to be construed as being without limitation to such specifically recited examples and conditions. As a result, the invention is not limited to the specific embodiments or examples described below.

(22) FIGS. 1-6 illustrate various views of a garden protection system 10, in one exemplary embodiment. In this embodiment, the garden protection system 10 comprises rigid legs 16 (e.g., hollow aluminum) that may be bolted to roofing members 12 at joints 14. The legs 16 are operable to bolt to sides of a garden box 20 which comprises a raised garden bed 18. Alternatively or additionally, the legs 16 may comprise feet that may be mounted to a surface (e.g., the ground) via holes that accept stakes for securing to the surface.

(23) Mounted to the top of the garden protection system 10 where the roofing members 12 connect is a housing 24 that is operable to provide environmental protection to underlying components, such as the pulley system 34, a roller system 32, a motor (not shown), various electronics and circuitry (not shown), a battery system (not shown), etc. Configured with the housing 24 is a solar panel 22 which is operable to provide power to the battery system and thus the electronics and the motor.

(24) In other embodiments, the legs 16, joints 14, and roofing members 12 at each end of the garden protection system 10 are formed as a single unit or using fewer or more rigid parts. In whatever the configuration, these frames provide support for the housing 24 and the various components thereof. In some embodiments, the height of the frames may be changeable so as to adapt for the garden bed 18 to grow varying size plants.

(25) One or more rolls of a shade cloth 26 (e.g., a mesh material) may be rolled onto the roller system 32 so as to slide the shade cloth 26 along the roofing members 12 and down the legs 16 so as to protect the garden bed 18 during periods of inclement weather (e.g., hail, extreme sun, heat, torrential rain, wind etc.). For example, a bracket 28 may be configured with rollers 30. And, each bracket 28 may be dimensioned about each roofing member 12, joint 14, and leg 16 and configured with at least one roller 30 slidably affixed to the frame. Thus, when the roller system 32 is activated within the housing 24, the shade cloth 26 rolls down from the top of the garden protection system 10 along the roofing members 12, the joints 14, and the legs 16. The combined weight of the brackets 28, the rollers 30, and the shade cloth 26 may provide enough pull such that when the roller system 32 unrolls the shade cloth 26, the shade cloth 26 rolls down along the sides of the garden protection system 10 (e.g., via gravitational force limited by the amount of turns of the roller system 32, the pulley system 34, and the motor), as illustrated in FIGS. 5 and 6. In some embodiments, the motor and the roller system 32 may only partially enclose the garden protection system 10 (e.g., so as to provide shade garden box 20 and the garden bed 18 therein).

(26) In some embodiments, the shade cloth 26 may be configured with a retention rod 38 that is operable to retain the shape of the shade cloth 26 such that it rolls along the legs 16, joints 14, and the roofing members 12 in a controlled manner. The retention rod 38 may also prevent sagging that could compromise the shade cloth 26 and cause damage to the underlying garden bed 18 during heavy rain and/or hail. In this regard, the shade cloth 26 may have a sewn pocket through which the retention rod 38 slides to mechanically couple to the brackets 28 on one side of the frame.

(27) Also configured with the housing 24 is a moisture detector 36 that is operable to detect excessive moisture from rain and/or hail. For example, when excessive moisture is detected by the moisture detector 36, the motor within the housing 24 may automatically activate to turn the pulley system 34, and thus the roller system 32, to automatically roll the shade cloth 26 along the sides of the garden protection system 10, as illustrated in FIGS. 5 and 6.

(28) In one embodiment, the shade cloth 26 is a woven material that is selectively chosen depending on the amount of sunlight and/or water desired on the garden bed 18. In this regard, the shade cloth 26 may be at least partially transparent yet configured to limit the amount of moisture into the garden bed 18 while preventing hail and/or winds from damaging plants therein. In one embodiment, the shade cloth 26 is wrapped around a roll tube of the roller system 32, and at the end of the roll tube is the pulley system 34 that is coupled to the motor and is operable to rotate the roll tube such that the shade cloth 26 may be lowered and retracted. Generally, the garden protection system 10 is configured with two such roll tubes so as to roll a shade cloth 26 along each side of the garden protection system 10. These roll tubes may be configured to roll the shade cloth 26 down both sides of the garden protection system 10 at the same time to cover the garden bed 18. Alternatively, the roll tubes may be configured to roll independently so as to provide shade for the garden bed 18 for different times of the day as the sun changes position. In some embodiments, the electronics may detect the sun's changing position and automatically deploy all or a portion of the shade cloth 26 (e.g., via an amount of solar energy being detected and/or temperature sensors). Other embodiments may include gears that are affixed to the motor and to the roller system 32 to roll out the shade cloth 26.

(29) The roller system 32 may be configured under the housing 24 so to protect the shade cloth 26 from sun and other weather conditions when the shade cloth 26 is not deployed, as such may shorten the lifespan of the shade cloth 26. The housing 24 may also protect against birds and other animals chewing and tearing holes in the shade cloth 26 that would allow for large hail stones and excessive water into the garden bed 18.

(30) In one embodiment, when water (e.g., rain and/or hail) makes a connection with the moisture detector 36, the moisture detector 36 directs the motor to unroll the shade cloth 26 and cover the garden bed 18. And, when the moisture detector 36 dries (e.g., when the rain and/or hail stops), the moisture detector 36 may automatically engage the motor to retract the shade cloth 36 by turning the roll tubes in the opposite direction. The moisture detector 36 may be flush mounted into the housing 24. In some embodiments, moisture detector 36 may include a glass screen similar to that of a smart phone touch screen interface that is operable to detect moisture and configured to be more durable to weather.

(31) The solar panel 22 may be configured with the garden protection system 10 to charge batteries (not shown) that power the motor. The batteries may be located in the housing 24 along with the motor and any circuitry required to activate the motor

(32) In some embodiments, the garden protection system 10 can be configured as a modular system, as illustrated in FIGS. 7 and 8 (e.g., garden protection systems 10-1, 10-2, 10-3, . . . , 10-N, where the reference N merely indicates an integer greater than 1). For example, a person may wish to have a series of garden boxes 20. The embodiments herein may be adapted for sheltering each garden box 20 independently. In this regard, the garden protection systems 10 may be independently controlled based on an amount of rain and/or sunshine the underlying plants may require. For example, corn is generally a hardier plant than flowers. Thus, one garden box 20 planted with corn may be configured with a garden protection system 10 that is configured to allow more sunshine and rain than an adjacent garden box 20.

(33) In some embodiments, the moisture detector 36 may be configured to measure an amount of moisture via analog output pins so that one can determine when a threshold of moisture is exceeded. The moisture detector 36 may include an electronics module and a printed circuit board (PCB) that collects the raindrops. Thus, as raindrops are collected on the circuit board, the raindrops can create paths of parallel resistance that are measured via an operational amplifier (e.g., an LM393 op-amp). In this regard, more water may lower the resistance and lower the voltage output. Conversely, less water may increase the resistance and increase the output voltage on the analog pin. In one embodiment, a completely dry board may, for example, cause the moisture detector 36 to output about five volts to activate the motor. However, the embodiment is not intended to be limited to any particular voltage output.

(34) In some embodiments, the solar panel 22 converts the solar radiation into electricity and/or heat (e.g., via the photovoltaic effect) and may include cells that are arranged in a grid-like pattern on the surface of the solar panel 22. Thus, it may also be described as a set of photovoltaic modules, mounted on a structure supporting it.

(35) In one embodiment, the motor is a 12 volt motor and is capable of rolling and unrolling the shade cloth off a 12 volt DC (direct current) battery. However, any suitable power source and motor may be used. Exemplary DC motors include shunt-wound motors, step motor, series-wound motors, compound-wound motors, and permanent magnet motors. DC motors may be used and configured to operate at a fixed speed for a fixed voltage with little to no slip. In some embodiments, the motor is an AC (alternating current) motor to which is supplied by an external AC power source. In other embodiments, the AC power source is operable AC to the battery as a charger to the battery. In this regard, the various circuitries may also include an AC to DC converter. In some embodiments, the AC power source is operable as a battery backup if the battery fails to hold a charge and/or drops below a certain level that allows for the deployment of the shade cloth 26.

(36) In some embodiments, the rollers 30 have bearings and are configured to be similarly dimensioned to the frames (e.g., the roofing members 12, joints 14, and legs 16) of the garden protection system 10 so as to keep the shade cloth 26 attached to the frames and on track to smoothly roll up and down when activated. When the shade cloth 26 is down, the rollers 30 may be configured to hold the shade cloth 26 in times of inclement weather and to shelter plants in the garden bed 18.

(37) FIG. 9 is an exemplary diagram of a moisture detector 36 and its associated circuitry, in one exemplary embodiment. As mentioned, associated circuitry may be configured within the housing 24 so as to protect circuitry from the environment.

(41) FIG. 14 is an exemplary circuit diagram of a battery level monitor 58 and is operable to monitor the amount of power that the battery of the garden protection system 10 is operable to provide. In some embodiments, the battery level monitor 58 may be operable to detect when the battery will soon no longer be operable to provide the necessary power to lower the shade cloth 26. In this regard, the battery level monitor 58 may provide an alert to the user and/or direct the shade cloth 26 to be automatically lowered so as to prevent inclement weather from harming the garden bed 18 after the battery level is incapable of providing the power necessary to lower the shade cloth 26.

(42) FIG. 15 is an exemplary microcontroller 60 that is operable to control each of the components of the garden protection system 10 (e.g., the motor, the solar powered battery charging system 50) and/or process data from each of the components of the garden protection system 10 (e.g., the moisture detector 36, the stepper motor driver 52, etc.).

(43) FIG. 16 is a circuit diagram of an exemplary capacitive rain sensor 62 that may be operable with the moisture detector 36.

(44) FIG. 17 are circuit diagrams of exemplary infrared remote receivers 64 (e.g., a communications module). For example, when a user is proximate to the garden protection system 10, the user may desire to provide shade to the garden bed 18. In this regard, the user may operate an infrared remote control that directs the garden protection system 10 via one or more of the infrared remote receivers 64 to activate the motor and roll down the shade cloth 26. Alternatively, when the user wishes to provide more sunlight to the garden bed 18, the user may operate the infrared remote control to direct the garden protection system 10 to activate the motor and roll up the shade cloth 26. However, the embodiments herein are not intended be limited to just an infrared remote control of the garden protection system 10. Other embodiments of the garden protection system 10 may include other forms of remote control including Bluetooth signaling and Wi-Fi signaling such that the user may control the garden protection system 10 from a computer, a smart phone, a tablet computer, or the like.
