Wirelessly Deployable Marker Flag System

摘要

A wirelessly deployable marker system is provided that allows a user to remotely activate one or more marker flags from individual marker flag assemblies when marking the location of landmarks and obstacles on a lawn. Each marker assembly comprises an elongated marker flag supported by a housing and spring-biased within the housing to elevate the marker into a deployed state. A solenoid latch secures the marker flag within the housing when pressed thereinto, while a wireless transmitter is used to activate the solenoid and therefore release the marker flag from the housing. The solenoid latch engages the marker flag when the flag is within the housing, and allows a spring to elevate the marker flag from the housing when the solenoid latch is withdrawn from the flag. In this way, the flag is remotely deployable, and thereafter can be inserted into the housing manually by the user.

主权项

1) A marker flag system, comprising:
a wireless transmitter; a marker flag assembly comprising:
an elongated marker supported within a marker housing, said marker having an upper end and a lower end;a marker housing supporting said elongated marker therein, said marker housing having a lower portion and an open upper portion;a marker spring connecting said lower end of said marker to said lower portion of said marker housing and biasing said marker through said open upper portion of said marker housing;a solenoid latch comprising a solenoid plunger, a plunger spring, and a coil winding;said solenoid plunger configured to be biased by said plunger spring toward said elongated marker when said elongated marker is within said marker housing;said solenoid plunger having a distal end configured to engage a notch along said elongated marker when said marker is disposed within said marker housing and said marker spring is compressed;said solenoid further comprising a power source and a solenoid switch that allows current to flow to said coil winding when said solenoid switch is closed; a wireless receiver in electrical communication with said solenoid switch; said wireless transmitter configured to send a signal to said wireless receiver, and said wireless receiver configured to close said solenoid switch upon receipt of said signal.
