  • Patent number: 6450425
    Abstract: The present invention is related to a connector structure of a wall hanging type shower head, including a body, a connector, and a positioning nut positioning the connector on the body. A positioning ring is mounted between the rotation portion of the connector and the positioning nut. The positioning ring has an inner periphery provided with a limit edge rested on the rotation portion of the connector, and has an outer periphery formed with a positioning shoulder rested on the positioning nut. The positioning shoulder may be locked with the positioning nut to prevent the positioning nut from contacting the rotation portion of the connector directly, thereby preventing the rotation portion of the connector from being worn out, so as to increase the lifetime of the rotation portion of the connector.

  • Patent number: 5632049
    Abstract: A holder assembly for a shower arm of a shower head includes a positioning body defining a vertical bore therein through which a vertical rod extends, which, in turn, is mounted to a wall of a bathroom. The positioning body includes an opening defined in an outer periphery thereof and communicated with the vertical bore, a pair of lugs formed on the outer periphery thereof and between which the opening is defined, and a lever pivotally connected to the lugs and including an operative end with an eccentric operative edge. A connecting part extends from the outer periphery of the positioning body. A shower arm holder includes a holder ring for removably holding a shower arm and is attached to the shower arm holder to the connecting part of the positioning body. The positioning body is frictionally held in position on the vertical rod when the lever is in a first, secured position. The positioning body is movable relative to the vertical rod when the lever is in a second, released position.
