Abstract: A support rack for a bathroom includes a first support frame, a second support frame, a plurality of guide tenons, and a plurality of placement rods. Thus, the second end of each of the placement rods is inserted into the respective mounting recess of the second support frame by guidance of the respective guide tenon, so that each of the placement rods is mounted between the first support frame and the second support frame easily and rapidly, thereby facilitating a user mounting the support rack. In addition, the second end of each of the placement rods is clamped between the respective mounting recess and the respective guide tenon so that each of the placement rods is positioned rigidly and stably, thereby preventing the placement rods from detaching from the second support frame.

Abstract: A support device includes a head, a lock nut threaded to the head and having a peripheral flange, and a control ferrule having a peripheral rib engaged with the peripheral flange of the lock nut, to rotatably attach the control ferrule to the head with the lock nut. A coupler includes a shank, and an arm secured to the shank and attached to a frame device, a rod is extended from the shank and engageable through the lock nut and into the head. One or more fasteners may secure the shank to the frame device. The shank is threaded to the control ferrule, to secure the shank and the frame device to the head, and the fastener is received and shielded within the control ferrule.

Abstract: A faucet includes a space coupled to a sprayer device and water reservoirs, and a valve device received in the space of the faucet for controlling the water to flow out through either the faucet or the sprayer device. The valve device includes a housing secured in the space of the faucet, a valve stem slidably received in the housing, a plug secured on top of the valve stem, and another plug secured to the lower portion of the valve stem and having a flat upper surface for engaging with the lower peripheral portion of the housing and for solidly blocking the water.

Abstract: A faucet device includes a faucet member having one or more ports for coupling to water reservoirs and a water outlet. The faucet member includes a hole and a chamber communicating with each other. A hose has one end coupler for selectively securing to the hole of the faucet member, and a sprayer device coupled to the other end. A valve device may be used for controlling the water to flow out through the sprayer device and the outlet of the faucet member. A lock cap may be selectively secured to the hole of the faucet member when the coupler is disengaged from the faucet member.
