摘要:
A chair type massage machine that enables a massager to effectively perform massages, ensures safety, reduces costs, and allows for easy attachment and removal of a cushion to and from a backrest. The massage machine includes a massage unit (5) that may be raised and lowered in a backrest (2). The massage unit (5) includes a massager (7) projecting toward the front from the backrest (2). A cushion (4) is formed to be generally U-shaped and arranged on a front surface of the backrest (2). The cushion (4) includes an opening (8) in which is arranged the massager (7), which is lowered and raised with the massage unit (5). The massager (7) is movable in the opening (8) of the cushion (4). A fastening means fastens the cushion (4) to the front surface of the backrest (2). The fastening includes hook-and-loop fasteners (10, 11) that are separated by application of downward external force of a certain amount or more to a lower rim of the opening (8) in the cushion (4).

A chair-type massage machine includes a seat on which a user sits; a leg rest whose one end portion is pivotally connected with a front portion of the seat for pivotal movement up and down, the leg rest supporting calves of the user; a driving unit for pivotally moving the leg rest with respect to the seat; a footrest pivotally connected with the other end portion of the leg rest for pivotal movement up and down, the footrest supporting feet of the user; and a massage means provided to at least one of the leg rest and the footrest. Also, a stopper unit is provided for restricting a pivotal movement range of the footrest with respect to the leg rest, and a biasing unit is disposed for applying a biasing force to the footrest in either an upward or downward a direction of the pivotal movement.

A leg rest 5 is pivotally secured to a front portion of a seat 2 of a chair 1 for pivotal movement up and down and operable to support calves of a seat occupant sitting on the seat 1, and a footrest 6 is pivotally secured to a front end of the leg rest 5 for supporting feet of the seat occupant sitting on the seat 2 ranging from ankles to toes and soles. The leg rest 5 and the footrest 6 are provided with respective massaging means 7 and 8 incorporated therein. Also, the leg rest 5 is provided with the distance thereof relative to the seat 2 being adjustable, and the footrest 6 is maintained substantially horizontally at all times regardless of the angle and the position of the leg rest 5.

A numerical control device controls a machine tool having an X axis for moving a turret to which tools are attached, a Z axis for moving work, and a B axis for rotating the turret and having at least one of an H axis for rotating the turret around a center line perpendicular to the center line of rotation of the B axis and a C axis for rotating the work around a center line parallel to the Z axis. The numerical control device includes a unit that performs, during an virtual Y-axis inclined surface machining mode, virtual Y inclined surface machining for moving the tool along the Y axis relatively to the inclined surface in a state in which the tool is inclined such that a center axis is perpendicular to an inclined surface inclined from the X axis and the Z axis.

A numerical control device that controls a machine tool that includes an X-axis for moving a turret, an H-axis for rotating the turret, and a C-axis for rotating a workpiece and that does not have a Y-axis orthogonal to the X-axis, including an analyzer that analyzes a virtual-Y-axis rapid-traverse command in a virtual-Y-axis interpolation mode in which an X-Y-axis movement command in a machining program is converted, and the X-axis, the H-axis, and the C-axis are cooperatively driven; a C-axis interpolation processor that interpolates a C-axis angle in response to the analyzed virtual-Y-axis rapid-traverse command; and an X-axis interpolation processor that interpolates an X-axis position based on the interpolated C-axis angle. The numerical control device controls an X-axis position so as to rotate the C-axis while keeping a C-axis velocity to a constant velocity and to enable a virtual Y-axis to move substantially linearly.
