  • Patent number: 11608675
    Abstract: A safety gate has a gate body and two first locking units. The gate body has two first connecting elements. The two first locking units are respectively mounted on two opposite sides of a door frame. Each first locking unit has a second connecting element and a blocking element. When the safety gate is closed, each of the first connecting elements is connected with a respective one of the second connecting elements. Each blocking element has a blocking position for blocking a corresponding first connecting element to prevent the corresponding first connecting element from being disengaged from the second connecting element and a pressed position to allow-the corresponding first connecting element to detach from the second connecting element of the first locking unit.

  • Patent number: 11359432
    Abstract: A safety gate has a first post assembly, a spinning mechanism, a cover body, and a positioning mechanism. The spinning mechanism is rotatably mounted in the first post assembly. The cover body has an edge mounted in the spinning mechanism. The gate body is wound around and is pulled out from the spinning mechanism to spin the spinning mechanism. The positioning mechanism has a knob and a positioning mount. The positioning mount is moved upwardly or downwardly relative to the spinning mechanism to selectively disengage from and engage with the spinning mechanism. The spinning mechanism is prevented from spinning while being engaged with the positioning mount.

  • Patent number: 11149488
    Abstract: A safety gate has two wall-mounted post assemblies, a main frame, and two connecting assemblies. The wall-mounted post assemblies are mounted on walls on two sides of the entrance. The main frame has a first frame portion, a second frame portion, and a sliding set. The sliding set connects the first frame portion and the second frame portion so the first frame portion and the second frame portion can slide with respect to each other to adjust an overlapping area. The connecting assemblies are mounted on two sides of the main frame and detachably mounted on the wall-mounted post assemblies. Therefore, the main frame is detachably mounted on the walls. Besides, the first frame portion and the second frame portion can be moved with respect to each other, so the occupied space is smaller and it is easy to control the blocked range of the entrance.

  • Patent number: 11066871
    Abstract: A retractable safety gate has a mesh fabric, a retracting mechanism connected with a first side of the mesh fabric, and a fastening mechanism connected with a second side of the mesh fabric. The retracting mechanism includes a bottom bracket, a fastening bracket, a first mounting tube, a locking assembly, and an energy storage assembly. The first mounting tube is rotatably mounted in the bottom bracket and the fastening bracket. The mesh fabric is wound around the first mounting tube. The locking assembly is mounted on the first mounting tube and selectively engages with the fastening bracket. The energy storage assembly is mounted in the first mounting tube and provides a resilient restoring force that drives the first mounting tube to wind the mesh fabric around the first mounting tube. The retractable safety gate rolls the mesh fabric up automatically and is convenient for use.

  • Patent number: 11015386
    Abstract: A safety gate has two wall-mounted post assemblies, a main frame, and two connecting assemblies. The two wall-mounted post assemblies are mounted to two walls of an entrance. The main frame has two frame portion. The two frame portion can pivot with respect to each other. The two connecting assemblies are mounted on two sides of the main frame and detachably and pivotally connected to the wall-mounted post assemblies. A stopping assembly is elastically mounted on a side, near the main frame, of each wall-mounted post assembly and configured to limit one of the connecting assemblies. With such safety gate, a user can press either one of the stopping assemblies to withdraw into the wall-mounted post assembly, and the corresponding connecting assembly can be separated from the wall-mounted post assembly to open the safety gate. When the two stopping assemblies are pressed, the main frame can be detached.

  • Patent number: 10927595
    Abstract: A safety gate has a main frame, two wall-mounted assemblies, and two connecting assemblies. The two connecting assemblies are respectively and movably mounted on two opposite sides of the main frame. Each connecting assembly has a first connecting part and a second connecting part. Each wall-mounted assembly has a first pivot base and a second pivot base. Each first connecting part is rotatably and detachably connected to a corresponding first pivot base. Each second connecting part is rotatably and detachably connected to a corresponding second pivot base. By detaching and rotating one connecting assembly from the corresponding wall-mounted assembly, the main frame can be closed and opened as a gate. By detaching all the connecting parts from the corresponding bases, the main frame can be easily installed on and disassembled from a place.

  • Patent number: 10683700
    Abstract: An easy-open safety gate for a barrier has a first door panel, a second door panel, a positioning assembly, and a locking assembly. The positioning assembly has a positioning base securely attached to a lower end portion of the first door panel, and an engaging member securely attached to a lower transversely bar of the second door panel and detachably engages with the positioning base. The locking assembly has a resilient locking member mounted in an upper end portion of the first door panel, and a locking housing pivotally mounted on an upper transverse bar of the second door panel and detachably engaging with the resilient locking member. No threshold is disposed below the safety gate. A user can unlock the locking assembly and rotate the second door panel with only one of his/her hands, which is convenient and safe for the user to open the safety gate.
