The present disclosure is related to pool blanket cover reels. More particularly, the present disclosure is related to a powered pool blanket reel that, through user activation, covers or uncovers a swimming pool.
Pool blankets have become a popular accessory for swimming pools. A pool blanket is a large shroud made of materials, such as polyethylene or vinyl, that selectively covers the open top of the swimming pool. Typically the blanket is rolled up onto a spool or roller to uncover the swimming pool while in use. The blanket can then unroll and cover the pool while not in use. Pool blankets are beneficial because they reduce evaporation which reduces heat loss in the pool. In addition, such blankets may allow sunlight to penetrate to heat the surface of the water. These blankets also keep debris such as leaves and dirt out of the water, thereby reducing maintenance.
The pool blanket of the present disclosure illustratively includes a pool blanket that extends the width of the pool and is wound on a roller suspended from each side of the pool. To cover the pool, the blanket is unwound and floated on the water from one end to the other. To use the pool, the roller winds the blanket up exposing the water underneath. This is a contrast to automatic pool safety covers that are built into in-ground pools that provide a load-bearing cover over the pool.
A pool reel assembly of this disclosure illustratively includes a roller that is vertically adjustable between the pool and the diving board. This adjustability allows the same pool reel to be used with different pools having a variety of widths and distances between the top of the pool and the bottom of the diving board. This configuration is useful even when the distance is unknown. The adjustability and height of the roller assure that the blanket will fit underneath the diving board.
Another illustrative embodiment of the present disclosure includes a safety control system built into the operation of the blanket reel assembly. The safety features encourage the operator to visually inspect the pool prior to operating the blanket reel.
Another illustrative embodiment of the present disclosure provides a pool blanket reel assembly that comprises a motor base, an idler base, a roller bar, a motor bracket, a motor, an idler bracket, an idler hub, a power supply, a switch, a remote control, and a remote control timer. The motor bracket extends from the motor base. The motor is adjustably mountable to the motor bracket. The motor bracket includes a slot with which the motor is selectively attachable adjacent the periphery of the slot. The idler bracket extends from the idler base. The idler hub is adjustably mountable to the idler bracket. The idler bracket includes a slot with which the idler hub is selectively attachable adjacent the periphery of the slot. One end of the roller bar is attachable to the motor and another end is attachable to the idler hub. The roller bar is suspendable between the motor and idler bases. The motor is configured to selectively rotate the roller bar in either clockwise or counterclockwise directions. The roller bar is configurable to attach to a pool blanket to roll and unroll the blanket. The roller bar also comprises a first bar portion and second bar portion such that each of the bar portions are connectable to make the roller bar's length selectively adjustable. The motor and idler are attachable to a plurality of positions along the length of the slots in both the motor and idler brackets so the roller bar can be adjusted to a plurality of heights above the motor and idler bases. The power supply is attached to the motor to rotate the motor in clockwise and counterclockwise directions. The switch has on and off positions and is in communication with the power supply to selectively permit or deny power to the motor. The remote control illustratively includes retract and extend button. When the switch is in the on position, the switch is configured to activate a first timer which limits the available time a remote control can activate the motor to a first predetermined period of time. During periods when power is permitted to be supplied to the motor, the remote control is configured so that if both buttons on the remote control become depressed simultaneously, power can be supplied to the motor for a second predetermined period of time. Subsequently, depressing either the retract or extend button during this second predetermined period of time will activate the motor causing it to rotate in either clockwise or counterclockwise directions. The motor will not rotate without the sequence of the switch moved to the on position, followed by the depressing both buttons on the remote control and then pressing either one of the buttons on the remote control again. The remote control receiver includes a remote control timer that limits activation of the motor for a third predetermined period of time; and wherein the power to the motor is uninterrupted by the first or second predetermined periods of time.
Further embodiments may comprise the slot in the motor bracket and in the idler bracket each including a periphery having a plurality of holes located adjacent thereto on each side of the slots. The holes on each side of the slot of the motor bracket may be configured to position the motor at different locations on the motor bracket. The holes on each side of the slot of the idler bracket are configured to position the idler hub at different locations on the idler bracket. Fasteners can engage the holes to secure the motor on the motor bracket and the idler hub on the idler bracket.
Additional features and advantages of the powered pool blanket reel assembly will become apparent to those skilled in the art upon consideration of the following detailed descriptions exemplifying the best mode of carrying out the powered pool blanket reel assembly as presently perceived.

Drive assembly 16 includes base 62 with its own bracket assembly 90 extending therefrom. In this illustrative embodiment, a slot 92 is disposed through a bracket, similar to slot 78 of bracket 76 from idler assembly 14. Roller 12 can position anywhere along the length of slot 92 to affect the height of roller 12 above the pool. In this illustrative embodiment, a gear motor 94 attaches to a motor mount 96 that attaches to bracket assembly 90. Roller portion 24 attaches to drive hub 98 via fastener 100. Collar 102 attaches to gear motor 94 via pin 104 to connect gear motor 94 to roller 12.

To position motor mount 96 to a desired height above the pool, it is attached to bracket face 120 via holes 122 disposed about the periphery of slot 92. Mounting bolts 126 illustratively dispose through star washers 124 and extend through holes 122. Holes 122 extend the periphery of each side of slot 92 in order to allow motor mount and, thus, roller 12 to be raised or lowered as desired. It is contemplated that the position of these holes 122 corresponds to holes 85 on the periphery of opening 78 of bracket 76 on idler assembly 14. (See

Conversely, to roll out the blanket, button 160 can be momentarily depressed. In this instance, an extension signal 159 is sent to antenna 156 from remote control 150 and into receiver 154 which sends signal 159 to relay 158. Unroll signal 159 is then transmitted to gear motor 94 to initiate the roll up process. Gear motor 94 then rotates in the opposite direction unrolling the blanket.

Another illustrative embodiment of the present disclosure includes a safety control system built into the operation of the blanket reel assembly. In an illustrative embodiment, the reel assembly includes a power system located within a reasonable proximity of the pool. Thus, even though a remote control is used, in order to get the remote control to operate the reel, a switch on the power supply is activated manually. Because the switch is in proximity to the pool, an operator can visually inspect the pool to confirm no one is still in the pool before activating the reel. Further, and in an illustrative embodiment, by switching the power supply “on,” a timer limits the amount of time within which to activate the remote control to move the reel. For example, by manually activating the switch to the “on” position, the system will provide power for illustratively five minutes before shutting off. Within that time the remote control needs to be activated. If not, the power will shut off requiring the operator to confirm no one is in the pool again before reactivating the blanket. It is appreciated that the time interval before shutting off power to the reel can be adjusted. Activating the remote control illustratively restarts the timer sequence. A new time limit to actually activate the motor begins. The motor is activated by illustratively activating one of the buttons on the remote again. The motor will continue to be activated for a predetermined amount of time (illustratively 60 seconds). The first two timed sessions are canceled allowing the motor to be activated for the full predetermined length of time. This last period of time, however, can be cut short if the button on the remote is depressed again. Otherwise it will continue for the 60 second predetermined period of time.
In an another illustrative embodiment, an off switch, which may or may not be part of the same switching system as the “on” switch, can be used to easily and manually shut the system down if needed. As another illustrative embodiment, the remote control itself may be equipped with multiple buttons or similar activators that require simultaneous activation in order to move the reel. For example, the remote control may include two buttons, both of which must be depressed simultaneously in order to activate the reel. This feature may make it difficult for younger persons to activate the reel.

Power cord 208, line filter 222, transformer 214, rectifier 220, and capacitors and resistors 221 take conventional 120 VAC and convert it into 12 VDC. Relays 218 are controlled by the remote control kit 216 to run reel motor 94. In an illustrative embodiment, a thermal breaker 217 will cut power to the motor if an overload occurs.
The chart in
After the remote control 150 has been activated, the operator has the choice to either push the retract button to start motor 94 to uncover the pool, or, conversely, push the extension button to start motor 94 in the opposite direction to cover the pool. The motor will continue for, illustratively, a predetermined period of time to either cover or uncover the pool. In an illustrative embodiment, that time may be about 60 seconds. It is appreciated that this time may change, depending on the needs of the reel assembly. As indicated by reference numerals 264 and 266, pushing either the retraction or extension buttons again during that 60 second period will cause the motor to stop. If either button is not pressed a second time to stop the motor as indicated by reference numeral 267, the motor will continue to run until the 60 second timer times out. This timer will essentially cancel the prior timers. At the end of the process, the key adjacent the power supply can be moved to the “off” position as indicated by reference numeral 268. This can be done at any time during the retraction or extension process. Indeed, this can serve as a master shut off if needed. If the power supply is not manually turned “off,” the remote will remain operational until the five minute timer times out or after the predetermined time allotted for the motor to run.
