Abstract
A swivel coupling device for rakes or other yard tools having handles that allows two of the implements to be quickly and easily connected for use of the combination to scoop, rake or the like various materials, and disconnected just as easily thereafter. The device includes a pair of clamp assemblies including tubular sleeves rotatably connected by a swivelable knuckle or in other words a swivel joint.
Claims20
A swivel coupling device for rakes, comprising:
- a first clamp assembly for a first rake, the first clamp assembly having i) a first tubular sleeve adapted to have a handle of the first rake extend therethrough along a longitudinal axis, and ii) a clamp including at least two fasteners, wherein when in a tightened state the clamp operatively connects the first tubular sleeve to the handle such that the handle can be rotated on the longitudinal axis without causing rotation of the first tubular sleeve;
- a second clamp assembly for a second rake, the second clamp assembly having i) a second tubular sleeve adapted to have a handle of the second rake extend therethrough along a longitudinal axis, and ii) a second clamp including a fastener, wherein when in a tightened state the clamp operatively connects the second tubular sleeve to the handle such that the second rake handle can be rotated on the longitudinal axis without causing rotation of the second tubular sleeve;
- and
- a swivelable joint rotatably connecting the first clamp assembly to the second clamp assembly, wherein the joint has a first segment connected to the first tubular sleeve and a second segment connected to the second tubular sleeve.

- a first clamp assembly for a first rake, the first clamp assembly having i) a first tubular sleeve adapted to have a handle of the first rake extend therethrough along a longitudinal axis, and ii) a clamp including at least two fasteners, wherein when in a tightened state the clamp operatively connects the first tubular sleeve to the handle such that the handle can be rotated on the longitudinal axis within and with respect to the first clamp assembly;
- a second clamp assembly for a second rake, the second clamp assembly having i) a second tubular sleeve adapted to have a handle of the second rake extend therethrough along a longitudinal axis, and ii) a second clamp including a fastener, wherein when in a tightened state the clamp operatively connects the second tubular sleeve to the handle such that the second rake handle can be rotated on the longitudinal axis within and with respect to the second clamp assembly;
- and
- a swivelable joint rotatably connecting the first clamp assembly to the second clamp assembly, wherein the joint has a first segment connected to the first tubular sleeve and a second segment connected to the second tubular sleeve;
- and
- wherein the second tubular sleeve comprises two sections with each section having a pair of flanges, wherein a hinge connects the flange of one section to one flange of the other section which allows the handle to be removed from the clamp assembly without having to slide the handle out of the clamp assembly in the longitudinal direction of the second tubular sleeve, wherein the flanges not connected to the hinge each include apertures which are connectable utilizing a fastener in order to operatively fix the second rake handle to the second clamp assembly.
