A floor panel is attached to the floor joists and exterior wall panels are attached to an exterior of the internal frame structure.

Abstract: Disclosed herein is a roller cover cleaning apparatus. The apparatus may include a handle and a wire that is coupled to the handle. The wire may form a helix that extends around an axis of the helix for more than 360 degrees. The wire may be substantially radially equidistant from the axis of the helix along the length of the wire from the proximal end of the helix to the distal end of the helix. The wire may be at least partially resiliently flexible to increase the radial distance between the wire and the axis.

Abstract: The invention relates to a locking device (11) with a bolt part (13) and a lock part (15) for arrangement on a room-closing element having an opening and a door (17) closing the opening. The bolt part (13) has a longitudinal guiding device (25) and a bolt (23) that can be displaced in a longitudinal displacement direction (21) with respect to the longitudinal guiding device (25). The lock part (15) has a receiving opening (29) for receiving a first end of the bolt (23). The bolt part (13) has in addition to the longitudinal guiding device (25) a transverse guiding device. Spring means (39), which are in active engagement with the longitudinal guiding device (25) and the transverse guiding device cushion a displacement of the bolt (23) in a transverse adjustment direction (47). The adjustment direction (47) is directed transversely to the displacement direction (21) of the bolt (23) and parallel to the door plane and is defined by the transverse guiding device (34).

Abstract: A collapsible barrel is provided for use in training for equine barrel racing. The collapsible barrel is configured and sized to approximate the dimensions of a conventional barrel used in the sport of equine barrel racing, but is constructed of sturdy, lightweight materials that enable the barrel to be transformed between a fully deployed state and a collapsed state. The collapsible barrel of the present invention is sufficiently lightweight and dimensioned, when in a collapsed state, to be easily transported, deployed for training and later stored. The flexibility of the collapsible barrel makes training ideal because it eliminates injury to the legs of the rider and the body of the horse.

Abstract: An adjustable receiver hitch system including a slide member that may be installed on a receiver tube attached to a vehicle, extending therethrough. Near the distal end of the slide member is disposed a rotationally pivotable bearing assembly. Interchangeable connection ends may be attached to the bearing assembly and are used to connect to a towed trailer. One interchangeable end may feature a height adjustment capability, while others may have fixed vertical heights. The system allows a user to adjust the attachment portion of the hitch in multiple ways to connect to a towed trailer to allow for attachment without an exact alignment between the primary vehicle and the trailer.

Abstract: An apparatus and method for forming a borehole in an earthen formation includes a side cutting device comprised of a cam assembly that includes at least one groove therein for selective extension and retraction of a laterally extending cutting element. Rotation of the side cutting device in a first direction causes the cutting element to be in a first retracted position so that a borehole having a first diameter can be formed. Rotation of the side cutting device in a second direction causes the cutting element to be in a second extended position. Rotation and retraction of the side cutting device when the cutting element is in the second extended position allows the side cutting device to create a larger borehole diameter in a down hole location.
