  • Patent number: 12193618
    Abstract: A toilet armrest, including a fixed seat and an armrest body; a first limit part is formed on the armrest body, the fixed seat is formed with a second limit part to limit the armrest body continues to swing at a lower limit position; a first clamp part is formed on the armrest body, a second clamp part is formed on the fixed seat; at least one of the first clamp part and the second clamp part is capable of being elastically deformed, so that the first clamp part passes through the second clamp part to provide resistance when the armrest body is swung into or out of the lower limit position. It enables the armrest to be securely swung to the side of the toilet seat for use by those with limited mobility, or to be swung to a position that avoids the toilet seat.

  • Publication number: 20240176174
    Abstract: A flexible dimming device and its fabrication method, a glass assembly, an automobile, and a glass curtain wall. The flexible dimming device includes: a first flexible substrate and a second flexible substrate opposite to each other; a liquid crystal layer sandwiched between the first flexible substrate and the second flexible substrate where the liquid crystal layer includes guest-host liquid crystals and dye molecules; a first electrode and a second electrode; and an anti-ultraviolet film on a side of the first flexible substrate away from the second flexible substrate. The first electrode is located on a side of the first flexible substrate close to the liquid crystal layer and the second electrode is located on a side of the second flexible substrate close to the liquid crystal layer. The anti-ultraviolet film and the first flexible substrate are bonded by a first adhesive film.
