A DIY flexible pipe with rigidity comprising a screw typed inner spring sheet, a screw typed outer spring member, a plurality of spring strips, a soft sleeve and many smaller sleeves; wherein, each layer (thread) of the inner spring sheet is provided with many engaging holes for insertion therein the spring strips having engaging teeth, the spring strips string multiple layers of the inner spring sheet, each spring strip in the layers of the inner spring sheet can also be strung up with many smaller sleeves, the inner spring sheet is slipped over with the outer spring member, and the soft sleeve is slipped over the outer spring member; thereby, a user can press to and fro on the pipe gradually as he likes to make a three-dimensional pipe having the curvatures desired, the spring strips, outer spring member and inner spring sheet in the areas bended are engaged with one another to construct a state which is provided with rigidity for bearing loading, or are mutually released to render the pipe to obtain flexibility in favor of adjustment and control in bending to form a shape, the pipe thus obtains an object of bending it in a simple and easy way and making it with fixed three-dimensional bending curvatures. Such pipe can afford making of bending pipe handicrafts or be used as a supporting pipe on a spine correction device.
A hose bending clamp (10) is described for holding a hose in a desired bent shape. The clamp (10) includes a coil 14 designed to slop over the outside over a section of hose to be bent. Each of the turns (12) of the coil are designed to constrain the hose so as to inhibit it from spreading or kinking as it is forced into the desired shape. A malleable spine (16) is provided in connection with the coil (14) and is designed to bend with the hose into the desired shape and to hold the shape when released.
A bend stiffener comprising a modular arrangement of alternating disks of rigid material and flexible material, each disk having a center hole arranged in axial alignment with the center holes of adjacent disks. The axially-aligned disks are arranged intermediate an end plate and a front plate, and are sandwiched together by one or more tensioned wires or other such elongated elements passing from the end plate to the front plate. Either or both the end plate or the front plate contain termination means for connection to a structure, such as for example bolts, threads latches or other locking mechanism.
