  • Patent number: 10342350
    Abstract: An anchor for rocking furniture including left and right flat-bottomed elements longer than wider, with width less than half the spacing between rockers of rocking furniture to be anchored. A forward element releaseably impedes the flat-bottomed elements from separating by more than the rocker width at a first point forward of a back leg of the furniture plus a gap substantially less that the width of the wider flat-bottomed element at the first point. The forward element is vertically positioned between flat-bottomed elements above the height of the rocker at the first point. A rearward element impedes flat-bottom elements from separating by more than the rocker width at a second point rearward of the back leg plus a gap substantially less that the width of the wider flat-bottomed element at the second point. The rearward element is vertically positioned between the flat-bottomed elements below the rocker at the second point.

  • Patent number: 8246341
    Abstract: A mold rotator with a first section and a second section that are engaged approximately perpendicularly to each other to produce a base and an L-shaped platform for receiving the article. The base of the article rotator may have a curved section at the intersection of the first section and the second section and the article rotator may rotate on its curved section between a first position wherein the article rotator is supported on its first section and a second position wherein the article rotator is supported on its second section. Further, the article rotator allows an article to be safely rotated simply by lowering the article onto the article rotator so that the article rotator automatically rotates approximately 90° from a first position and a second, rotated position. The article rotator may include a stabilizing system wherein the article rotator can be stabilized at both a first position and second position which is approximately 90 degrees from the first position.

  • Patent number: 7597397
    Abstract: A swivel rocker is provided that includes a surface designed to contact a floor so as to facilitate rocking in two directions along a line while limiting rocking in other directions and to inhibit excessive rocking in at least one direction along the line. The swivel rocker also includes a swivel portion such that a seat may be rotated relative to the two directions of facilitated rocking. The swivel portion allows a user to alter the directions of facilitated rocking relative to their orientation on the seat. The rocking surface inhibits excessive rocking in the at least one direction to help prevent the user from tipping over in the chair. Under some embodiments, the swivel rocker is formed of two rockers having a curved portion designed to contact the floor and an additional portion that inhibits excessive rocking. The additional portion extends from the curved portion in several embodiments.

  • Patent number: 7506922
    Abstract: The present invention relates to a reconfigurable child receiving device that includes a seat portion and arcuate leg members that support the seat portion above a supporting surface. The seat portion is further supported by arcuate cross members that extend between the leg members and are pivotally connected to the leg members. The arcuate cross member can each be individually pivoted upward above the leg members or downward below the leg members. The pivotal connection between the leg members and the cross members enables the reconfigurable child receiving device to be configured into four different modes of use. In a first mode, both arcuate cross members are pivoted upward above the leg members to allow the device to rock on the leg members in a first direction. In a second mode the second cross member is pivoted downward to prevent rocking in the first direction and to secure the seat portion in a relatively upright configuration.

  • Patent number: 6761405
    Abstract: A rocking chair including a body supporting portion, a chair base portion, a locking assembly arid a linkage. The linkage includes a strip of resilient material extending across the backrest of the chair, positioned to receive the back of an occupant of the chair. The strip has a resiliency such that, when an occupant leans back against the backrest of the chair, the strip is responsive to the pressure applied directly thereto to deform rearwardly from an original position and, when the pressure ceases, the strip returns to its original position. The linkage is operatively connected to the locking assembly to cause the locking assembly to prevent movement of the body supporting portion relative to the chair base portion when the strip is in the original position, and to cause the locking assembly to allow movement of the body supporting portion relative to the chair base portion when the strip is deformed rearwardly from the original position.

    Abstract: The rocking chair includes a ground-resting base, a seat support frame and rocking arms rockably mounting the seat support frame to the base. A seat, defining a front end portion and a rear end portion, is pivotally mounted on the support frame at its front end portion allowing limited up and down movement of its seat rear end portion between an upper position and a lower limit position. A stop is carried by said seat support frame and engages the seat rear end portion in its lower limit position. A spring continuously forces the seat towards said upper position, and the weight of a person seated on the seat rear end portion will effectively lower the seat rear end portion to its lower limit position against the bias of the spring.
