Abstract:
1. A foldable safety barrier to be secured in an opening, such as a door opening, a staircase or a window, and comprising a frame having an upper cross member and a lower cross member as well as first and second lateral posts, said upper and lower cross members as well as said first and second lateral posts being adapted to secure a covering which is defined by the upper and lower cross members as well as by the lateral posts, said upper and lower cross members consisting of two parts which are mutually displaceable so that a length of the upper and lower cross members may be adjusted, said lateral posts being provided with a hinge link to fold the lateral posts into a plane of the safety barrier, wherein outer dimensions of the hinge link and the first and second lateral posts are the same in a direction parallel to the upper and lower cross members when the safety barrier is in a folded-out state, and outer dimensions of the hinge link and the first and second lateral posts correspond closely in the direction parallel to the shafts of the hinge link, and the hinge links include a lock which comprises two push-buttons which are spring-loaded, said lock locking the lateral posts in a non-folded state and releasing the lateral posts when the safety barrier is to be folded together, the upper and lower cross members being coupled to the lateral posts with four angle brackets, each angle bracket having first and second bracket parts, said first bracket part being coupled to the lateral posts, said second bracket part being coupled to the upper and lower cross members, wherein fixing parts facing toward an opening are coupled to a free end of the second bracket part, wherein the fixing parts at one end of the upper cross member are formed by a threaded rod carrying a ferrule at a free end thereof, and at the other end by a threaded rod having a ferrule which is additionally coupled to a clamping device, wherein a pressure indicator is coupled to at least one of the bracket parts, the pressure indicator being formed by a sleeve having a thick part provided at one end which is affected by a spring disposed in a housing, which is arranged in the bracket and which consists of first and second sub-housings, and such that a first end of the spring engages the thick part of the sleeve and a second end thereof engages a shoulder in the first sub-housing, said sleeve having gripper hooks at a free end thereof which engage an opposite side of the same shoulder in the second sub-housing, said shoulder serving to define the first and second sub-housings.
