Definitions

  • An ad justabler device comprising two or more interconnected elements, said elements forming a preferably elongated chaing
  • the invention relates to a device which can be given a desired shape and which furthermore is equipped with means that permit the shape to be maintained for a shorter or longer more permanent period.
  • the device is therefore not intended to be limited to one special purpose, but can be envisaged employed within various fields where there is a need for a device that is ductile and where it will be an advantage for the shape of the device to be maintained by simple means.
  • Examples of applications that may be mentioned briefly here are measuring tools, templates, steps, ladders, support in connection with broken bones. Some of these applications will be described in more detail later.
  • the device according to the invention comprises two or more elements that are interconnected in such a manner that the elements form a preferably elongated linked, hose or chain shape.
  • the elements can be moved relative to one another in one, two or more planes in order to adapt the device to the desired shape.
  • the device is furthermore constructed in such a manner that the elements can be secured in position relative to one another when the desired shape replication has been attained. This is achieved by interaction between the elements' design and the means employed to hold the elements in the desired position.
  • the male portion may have a ball-like shape.
  • a male portion of this shape permits the elements to be connected as a universal joint and thereby enables them to be repositioned relative to one another on several planes, either when the male and female portions are interconnected or by the portions being released from one another and then rejoined in a new position.
  • the male portion in a plan view through the male portion will have a circular profile.
  • the male portion's lateral edges will be smooth and more or less straight.
  • the connection between the male and female portions will then be of the tongue-and-groove joint type and the repositioning of the elements relative to one another will occur substantially in one plane.
  • the female portion will have a cavity shape suitable for receiving at least one portion of the male portion.
  • the elements' through-going opening is preferably centred viewed in the element's cross section.
  • the through-going opening in the male portion in a plan view through the element may be in the form of a slot extending from the female portion's cavity and on into the male portion where it ends in a funnel- shaped opening in the male portion's surface.
  • the opening in the male portion's surface will be circular or slot-shaped depending on whether the male and female portions form a universal joint or a tongue-and-groove joint.
  • one end of the elongated body may be equipped with an end piece, which is suitable for abutment with the female portion in one of the elements at the end of the device, and which thereby secures this end of the elongated body relative to the device.
  • a gripping tool such as for example pliers or a tool that exerts hydraulic pressure may be employed for slackening and tightening the other end of the elongated body in order to vary the device between a position where the elements can be repositioned and a position where the elements are secured in position respectively.
  • the device according to the invention may have many areas of application and is therefore not limited to one purpose.
  • the length of the device may be adapted to suit the area of application, and the same applies for the dimensions of the individual element.
  • Various materials may be used for manufacturing the elements and low-weight, high-strength materials will be preferred such as, for example, aluminium or titanium. It will also be possible to manufacture the device in a plastic material.
  • the device When employed for this purpose the device will preferably be designed with a uniform and continuous shape at least at the side portion that has to be placed against an object for shape replication. The elements' dimension will therefore influence the device's tolerance level, i.e. the accuracy of the plasticity of the device will depend on whether the elements are large or small.
  • the individual element is provided with a collar portion near the male portion.
  • a portion of the element that encircles parts of the female portion's cavity is designed for reception in the space between the male portion and the male portion's collar. Interaction between the collar portion and the lower portion restricts the movement of the elements relative to one another.
  • Each element can be rotated approximately 0-90° relative to the element or elements with which it is connected. Altering the shape near the male portion can therefore cause the elements' angle of rotation to be increased beyond the interval 0-90°.
  • the elements' angle of rotation can be freely selected within the framework of the independent patent claim. Since the elements can be rotated relative to one another while they are interconnected and the central opening is designed as indicated earlier, the length of the elongated body located in the elements' through-going openings can be kept constant during the rotating movements.
  • a friction element is mounted at the opening in the male portion's surface in order to restrict the sliding movement between the elements' respective male and female portions.
  • the friction between the male and female portions ensures that the elements are substantially held in the position they are in, but is nevertheless not great enough to prevent the elements from being repositioned relative to one another by hand.
  • the device's lateral surfaces may be equipped with attachment means such as magnets to enable the device to be easily attached to the area that has to be measured or replicated and to the surface where the taking of measurements or shape replication are conducted.
  • Taking measurements or shape replication is performed by first placing the device in contact with the surface that has to be replicated. The device's elements are then adjusted/repositioned relative to one another so that by means of the device the shape that is replicated is approximately an identical copy. The device is then moved to another surface for shaping/taking measurements.
  • the elongated locking body for example the wire
  • the wire is slackened when the device is brought into contact with a surface in order to replicate a shape.
  • the wire can then be tightened, for example by a simple manual pressure on locking pliers, thus maintaining the shape concerned.
  • the device can then be moved in the locked position to the area where the new shape is to be manufactured. If pliers are employed to lock the wire, the pliers' locking position can be released by a release lever on the handle of the pliers. If the dimensions of the device are large, a hydraulic cylinder may be required to secure the wire relative to the elements.
  • the female portion's cavity is provided with a lug projection adapted for reception in one or more grooves provided in the male portion, preferably positioned about the male portion's circumference.
  • the elements are repositioned relative to one another by the male portion's lug projection being moved to a new groove in the male portion's circumference.
  • rigidity is achieved in the longitudinal direction when the elements are interconnected.
  • two devices (each with its elongated locking body) are employed according to the invention, positioned in such a manner that the devices viewed in their longitudinal direction form a substantially parallel relationship to each other and a tie bar is mounted between the two devices.
  • the tie bars When this assembled apparatus is to be employed as a ladder/steps the tie bars will act as ladder rungs, the elements' dimensions being relatively large and the elements preferably made of light metal.
  • a flexible ladder By tightening/releasing the elongated body and repositioning the elements, a flexible ladder is achieved which can be adapted to the height at which it is to be used and possibly converted to a scaffolding ladder.
  • the tie bars When the assembled apparatus acts as a support device in the case of broken bones, the tie bars will have a curvature that is adapted to the shape of the arm or leg.
  • two or more devices are incorporated in the assembled apparatus, and the individual device can be adapted to the shape of the arm or leg.
  • extra means such as straps are preferably employed to secure the assembled apparatus to the arm or leg.
  • the elements will be made relatively small and in a material that satisfies the regulation requirements for medical aids.
  • the female portion and the male portion are provided with slots extending in the circumferential direction substantially positioned perpendicular to the lug projections and the grooves. These slots make it possible to fold up the assembled apparatus.
  • At least one end of the elongated locking body is slackened and the elements are preferably folded alternately to one side or the other, thus obtaining a stack of elements where the elements are laid on top of one another.
  • the stacking is made possible by the fact that portions of the elongated locking element can be positioned in the slots of the male and female portions respectively. This will be explained in more detail in connection with the figures.
