Abstract
A device for leveling a surface; the device includes a shaft, a handle-means and a head-assembly. The shaft is selectively retractable, and the head-assembly is foldable to enable compact storage. The device is for personal use by a user in leveling a surface; for example, a sand bunker/sand trap on a golf course. In some versions, the device further includes an attachment-means for attaching the device to a bag.
Claims15
A device for leveling a surface, the device comprising:
- a shaft including an elongated profile having an adjustable length;
- a handle attached to a first end of the shaft;
- and
- a head-assembly attached about a second end of the shaft, the head-assembly including a mid-section, a first half pivotally attached to a first side of the mid-section, and a second half pivotally attached to a second side of the mid-section, the mid-section being attached to the second end of the shaft, the first half and the second half being pivotable between a folded-position and an in-use position, and wherein the first half and the second half in the in-use position are used to level the surface,
- the head-assembly further includes a pop-out mechanism, the pop-out mechanism including a first spring in communication with the first half and a second spring in communication with the second half, and wherein the first spring and the second spring impart a permanent bias on the first half and the second half toward the in-use position,
- the pop out mechanism further including a latch movable by a third spring between a first latch position and a second latch position, in the first latch position the latch retains the first half and the second half in either the folded or in-use position, and in the second latch position the latch permits movement of both the first half and the second half between the folded and in-use position, the third spring imparting a permanent bias on the latch toward the first latch position.
A sand rake for leveling a sand surface, the sand rake comprising:
- a shaft including an elongated profile having an adjustable length, the adjustable length being telescopic, the shaft further including at least a main shaft-section, a first telescoping-section, and a shaft lock, the shaft lock configured to selectively lock the shaft in an extended position, and the shaft lock further configured to selectively lock the shaft in a retracted position;
- a handle attached to a first end of the shaft;
- and
- a head-assembly attached about a second end of the shaft, the head-assembly including a mid-section, a first half pivotally attached to a first side of the mid-section, and a second half pivotally attached to a second side of the mid-section, the mid-section being attached to the second end of the shaft, the first half and the second half being pivotable between a folded-position and an in-use position, the head-assembly further including a pop-out mechanism, the pop-out mechanism including a first spring in communication with the first half and a second spring in communication with the second half, the first spring and the second spring imparting a permanent bias on the first half and the second half toward the in-use position, the pop out mechanism further including a latch movable by a third spring between a first latch position and a second latch position, in the first latch position the latch retains the first half and the second half in either the folded or in-use position, and in the second latch position the latch permits movement of both the first half and the second half between the folded and in-use position, the third spring imparting a permanent bias on the latch toward the first latch position,
- the folded position including a first length of the first half and a second length of the second half being substantially parallel to the adjustable length of the shaft, the in-use position includes the first length of the first half and the second length of the second half being substantially perpendicular to the adjustable length of the shaft;
- and
- wherein the first half and the second half in the in-use position together with the mid-section are used to level the sand surface;
- wherein the head-assembly includes a top side and a bottom side relative to the surface when the first half and the second half are in the in-use position;
- wherein the first half includes a first set of teeth attached to the bottom side;
- wherein the second half includes a second set of teeth attached to the bottom side;
- and
- wherein the mid-section includes a third set of teeth attached to the bottom side.
A method of using a device for leveling a surface, the method comprising the steps of:
- providing the device, the device including:
- a shaft including an elongated profile having an adjustable length;
- a handle attached to a first end of the shaft;
- and
- a head-assembly attached about a second end of the shaft, the head-assembly including a mid-section, a first half pivotally attached to a first side of the mid-section, and a second half pivotally attached to a second side of the mid-section, the mid-section being attached to the second end of the shaft, the first half and the second half being pivotable between a folded-position and an in-use position, and wherein the first half and the second half in the in-use position are used to level the surface, the head-assembly further includes a pop-out mechanism, the pop-out mechanism including a first spring in communication with the first half and a second spring in communication with the second half, and wherein the first spring and the second spring impart a permanent bias on the first half and the second half toward the in-use position, the pop out mechanism further including a latch movable by a third spring between a first latch position and a second latch position, in the first latch position the latch retains the first half and the second half in either the folded or in-use position, and in the second latch position the latch permits movement of both the first half and the second half between the folded and in-use position, the third spring imparting a permanent bias on the latch toward the first latch position;
- placing the first half and the second half of the head-assembly in the in-use position;
- adjusting the adjustable length of the shaft to a desired position;
- grasping the handle-means;
- and
- using the device to level the surface with the head-assembly.
