Definitions

  • the present invention relates to a support element for a screw clamp and a screw clamp, which can be better adapted to a variety of applications and fix a workpiece reliable.
  • clamps which are particularly intended for use on so-called Spanntica- or welding tables and each having a vertical and transverse strut.
  • the two struts are arranged at an angle of 90 ° to each other.
  • a threaded spindle is held, with the workpieces are fixable on the welding table.
  • the disadvantage is that these known screw clamps are limited in view of the flexibility of use and adjustability. Furthermore, torques can act on the known screw clamps, which lead to a workpiece can not be reliably fixed.
  • the first carrier element according to the invention for a screw clamp can have a first element which can have a substantially circular cross section and two free ends. Furthermore, a holder element, which may be arranged on one of the two free ends of the first element, and a substantially annular receiving element may be provided.
  • the receiving member may be rotatably mounted on the holder member and adapted to receive a fastener. Furthermore, a longitudinal axis of the first element and a longitudinal axis of the receiving element in a, preferably fixed, intersection, the position of which can be independent of a rotational position of the receiving element, cut. Furthermore, the receiving element can rotate about an axis of rotation, preferably on Holder member may be arranged, which may be perpendicular to the longitudinal axis, the first Eiementes and the longitudinal axis of the receiving element.
  • the longitudinal axis of the first element passes through the center of the substantially circular or annular cross-section.
  • the longitudinal axis of the receiving element extends through a center of the region into which the fastening means is inserted or inserted.
  • the longitudinal axis of the fastening means when this is arranged in the receiving element, is congruent with the longitudinal axis of the receiving element.
  • intersection of both longitudinal axes i. the first element and the receiving element need not be positioned within the two elements.
  • the point of intersection lies at least outside the first element, so that the point of intersection lies on an imaginary extension straight line of the longitudinal axis of the first element.
  • the receiving element is preferably based on the fact that an inner section has no material and this inner section is substantially circular.
  • the shape of the outer wall of the receiving element does not necessarily have to be circular.
  • the receiving element is preferably characterized in that it has a thread into which the fastening means or an adapter can be screwed. But there are also connections or frictional connections possible.
  • the longitudinal axis of the first element, the longitudinal axis of the receiving element and the axis of rotation of the receiving element according to the invention preferably along an imaginary three-dimensional Cartesian coordinate system, when the two above-mentioned longitudinal axes are arranged at a 90 ° angle to each other.
  • the carrier element according to the invention thus allows it, in particular in cooperation with a welding table or other components, such as an angle element or another support element, can be flexibly adjusted.
  • the flexibility is achieved in particular by the fact that the receiving element the Fixing means rotatably or pivotally holds, so that in particular workpieces can be fixed, for example, have curved surfaces.
  • the first element in particular when used in combination with welding tables and / or accessories therefor, can be inserted into a suitable receiving opening, so that in combination with the welding table and / or the accessory fixing arrangements can be assembled according to a particular application.
  • an advantage of the carrier element according to the invention that the first element, the pivot point / intersection and the longitudinal axis of the receiving element or of the fixing are arranged by means of a same imaginary plane. This causes the generation of undesirable torques can be reduced or reduced.
  • These are produced in particular in known screw clamps, in which e.g. the longitudinal axis of a fastener is not in the same plane as the longitudinal and transverse struts of the known screw clamps.
  • the flexibility of use of the first support element is further increased because this, when it is inserted or inserted into a counter-shaped receptacle, allows a rotational movement about the longitudinal axis of the first element.
  • the first carrier element offers two axes of rotation, which increase enormously the degrees of freedom when setting or adapting to a workpiece or to an application.
  • the holder element may have at least two legs.
  • the two legs may be arranged substantially L-shaped relative to each other.
  • the receiving element may be rotatably disposed on an inner wall of one of the two legs at least about the axis of rotation ' around.
  • the other leg may be connected to an outer wall at an end face of one of the two free ends of the first member.
  • the legs are preferably flat profiles whose height substantially corresponds to the diameter of the first element. For flat profiles a favorable weight reduction is possible, so. that the holder element is made very light and at the same time mechanically strong and stiff. Particularly preferably, a shorter leg is provided, whose outer side is connected to the end face of the first element planar surface and fixed. For this purpose, a welding or soldering connection are particularly suitable, if the individual elements are metallic, a Kiebeharm, preferably with plastic elements, and / or a screw connection.
  • a second, longer leg is preferably provided, which is arranged in an L-shape to the shorter leg, wherein the longer leg is preferably arranged parallel to the longitudinal axis of the first element.
  • the parallel arrangement of the longer leg allows a precise alignment of the receiving element to the first element.
  • the two legs can be directly connected to each other, also in one piece. However, it is also possible to provide an intermediate section which may be e.g. forms a radius-shaped transition between the two legs. The radius additionally increases the dimensional stability of the holder element.
  • the shorter leg may be rounded off at one end, so that the rounding substantially coincides with an outer contour of the first element. This allows for optimum weight savings and a compact, ergonomic design. Additionally or alternatively, the longer leg may be rounded at one end, so that the rounding substantially coincides with an outer contour of the first element. This allows for optimal weight savings and an ergonomic design.
  • outer wall of the legs is to refer to the holder element, so that the respective outer walls of the legs are those which are arranged on the convex side of the L-shape.
  • the inner walls of the legs are then corresponding to the concave side.
  • the wall surfaces of the legs are preferably designed plan, to allow the least possible complex shape.
  • the L-shaped holder element can preferably store the receiving element on one side.
  • This one-sided storage for example, by allowing the receiving element 'is arranged only on the longer leg and rotatably mounted there, causes another Material savings and thus weight reduction compared to a two-sided storage.
  • the L-shape of the holder element ensures a mechanical rigidity and dimensional accuracy of the holder element even when one-sided storage.
  • This arrangement and storage of the receiving element is structurally advantageous because no complex designed brackets must be provided and at the same time allows the longitudinal axes of the receiving element and the first element intersect and the receiving element can rotate as freely as possible.
  • the receiving element may have a partially open or closed ring shape with a thread in the region of the inner wall.
  • the thread may be configured to receive a thread of the fastener.
  • a partially open ring shape is possible, for example, when a part of the ring circumference is omitted, e.g. on a width corresponding to the diameter of a fastener. Preference is given to the complete ring shape. This lays a plugging or insertion of a fastener from above or below. Due to the thread and the stable ring shape, the fastening means can be securely held by the receiving element. The length in the longitudinal axis of the fastening means, which is each arranged laterally to the receiving element, can be changed or adjusted due to the thread by means of a rotary or screwing movement.
  • the receiving element may have arranged on an outer wall at least one shaft, which may be arranged in a hub of the leg of the holder element.
  • the arrangement can also be reversed, i.
  • a shaft provided on the leg and a receptacle or hub on the receiving element.
  • the shaft-hub connection allows the formation of an axis of rotation about which the receiving element can rotate around.
  • the compound can e.g. be secured by a screw or the like .. Such a construction can be produced with little effort, but allows a very reliable and precise function.
  • a screw connection can be provided which the Receiving element rotatably supports on the holder element.
  • a plan-shaped surface may be provided on the outer wall of the receiving element, which is in areal contact with the inner wall of the longer leg of the holder element and is pulled by a screw connection to the inner wall. This is another less complex and secure connection / storage option of the receiving element.
  • the first support member may include a rotating device that may include the shaft and the hub for rotatably supporting the receiving member on the holder member, and a contact portion in which a portion of an outer wall of the receiving member and a portion of an inner wall of the holder member may be in contact with each other, when the receiving element is rotatably mounted on the holder element.
  • the contact portion is the portion at which a portion of the holder member or its legs and a part of the receiving element at least slightly touch. This at least slight contact is the origin of a frictional force, which is too easy or automatic twisting. of the receiving element can prevent, if necessary. Furthermore, the frictional contact can be adjusted by a closer contact of the two sections so that the rotation of the receiving element with a predetermined, e.g. can be done by hand applied force. Of course, this is optional: It can also be provided no contact section.
  • the contact portion may constitute a sliding surface.
  • locking grooves and protrusions of the inner wall of the holder element and the outer wall of the receiving element may be in contact with one another at the contact portion.
  • the detent grooves and protrusions may be at least partially engaged so that an operator must apply a predetermined torque to effect rotation.
  • the rotary device can also have an elastic element, for example a spring, which acts axially in the direction of the axis of rotation and pulls the depressions and protrusions toward one another. The operator can then initiate a rotation, for example, in that he is in the axial direction of the axis of rotation of the receiving element, ie opposite. the spring force pulls and at the same time this rotates about the axis of rotation. When you release the receiving element, the spring pulls the wells and protrusions together again, so that further rotation is blocked or impeded again.
  • a distance between an inner wall of the leg of the holder element, which may be arranged at the free end of the first element, and an outer wall of the receiving element be at least equal to or greater than / as the distance between the intersection of the longitudinal axis of the first element with the Longitudinal axis of the receiving element and a point on an outer edge of the receiving element.
  • the outer edge is an edge of the Consejementes, which limits an outer circumference of the receiving element and at the same time an axial length thereof.
  • a point on the outer edge should be so far removed from the inner wall of the opposite leg as possible for a possible 360 ° rotation of the receiving elements without the fastening means as the distance to the pivot point of the receiving element. This distance can be determined by means of the length of the longer leg which holds the receiving element.
  • the distance is most preferably selected such that a fastening means is pivotable at least 90 ° clockwise and counterclockwise from a vertical position. If the distance is chosen so that it is slightly larger than the length of the fastener, then a 360 ° rotation can be achieved even with mounted fastener.
  • the radius of the outer wall of the receiving element may be equal to or greater than / as a radius of the first element.
  • the length of the receiving element may be at least as long as the diameter of the first element. This allows the carrier element to build as compact as possible.
  • the attachment means may be a threaded spindle or a quick release.
  • the fastening means can be arranged in a threaded adapter whose internal thread can substantially coincide with an external thread of the fastening means and whose external thread can substantially coincide with the thread of the receiving element.
  • Threaded spindles have different thread diameters. So that a flexible selection of threaded spindles, but also other components such as a quick release, is possible, adapter sleeves be provided, which have an adapted to the threaded spindle internal thread and an external thread that fits to the thread of the receiving element.
  • the adapter sleeves have the advantage that a very flexible use of different fastening means is made possible, which can be mounted with little (change) effort on / in the receiving element.
  • the two longitudinal axes of the two parts coincide in the 'substantially, that is, they are congruent. This prevents the generation of undesirable torques, since thus the first element, the pivot point of the receiving element and the longitudinal axis of the fastener lie in a same plane.
  • a screw clamp according to the invention may comprise a first carrier element according to the invention and a second carrier element.
  • the second carrier element may have a second element and a substantially circular cross-section.
  • the second element can have two free ends.
  • a substantially annular element may be arranged at one of the two free ends of the second element.
  • the annular element may be suitable for movably supporting the first element of the first carrier element.
  • the movable mounting of the first element or of the first carrier element in relation to the second carrier element improves the adaptability of the screw clamp to a wide variety of applications.
  • the longitudinal axes of the first and second elements are arranged in a same plane.
  • the annular element may have a circular ring section which is designed to keep the first element rotatable about its longitudinal axis and to be displaceable along its longitudinal axis. Moving along the longitudinal axis allows many different clamping ranges are adjustable. The twistability allows, in particular in combination with the further rotatability of the receiving element an optimal adaptation to eg the shape of a component to be fixed. Further, between a diameter of the circular ring portion and a diameter of the first element, a predetermined play or transition fit can be provided. Such fits are preferred, which allow a displacement and / or rotation of the first element in the circular ring section by hand. Other fits are of course possible.
  • the second carrier element may hold the first carrier element such that the longitudinal axes of the first and second elements may lie in a common imaginary plane, and an intersection of the longitudinal axis of the first element with a longitudinal axis of the receiving element may be arranged in the same common imaginary plane.
  • each of the first and second elements may substantially have the cross section of a round tube and both elements may have substantially the same radius. This allows the two elements to be mechanically very resilient. Due to the same radius, a variable combination of different first and second elements can be made possible.
