Definitions

  • the invention relates to a frame component according to the preamble of claim 1 and claim 2 and a modular work table formed therewith according to the preamble of claim 10.
  • a table plane of this turning table is formed by a plurality of strips, which can be arranged in parallel or else in the manner of a grid.
  • the individual strips of the turning table consist of a strip holder, which is designed as a C-shaped sheet metal profile.
  • a plastic body is inserted, which carries a plurality of rows of bristles, each projecting vertically upwards.
  • the free ends of the bristles are all in one plane, thereby defining a support or table level of this turning table.
  • the bristles have sufficient rigidity to define a horizontal support plane for plastic products.
  • each work tables for clamping workpieces known whose table surface can be changed in their dimensions at least one crimping component in the form of a supporting spar or carrier is provided which is displaceable horizontally and relative to an adjacent frame component. By this horizontal displacement, the dimension of a table surface, which is formed by these two frame members, can be changed in their dimensions.
  • such conventional worktables are subject to the disadvantage that the surface of the support beams or support, with which the workpieces come into contact, can be soiled by welding beads or the like or damaged by impacts or the like. For this case, a precise clamping of workpieces and a corresponding adjustment on the work table is not guaranteed. If the surface of a slidable frame member should be soiled or damaged, complete replacement of this component is cumbersome and expensive.
  • the invention has for its object to provide a work table and a frame member for such a work table, can be eliminated with the dirt and / or damage to the support surface for the workpieces inexpensively and quickly.
  • a frame component according to the invention is suitable for use for a work table in order, together with at least one further frame component to form or define its table surface.
  • the frame component according to the invention has a longitudinal extension and comprises a carrier element and a contact element, wherein the contact element is attached to the upper side of the carrier element and thereby forms a bearing surface for a workpiece.
  • the contact element is solid with a rectangular cross-section, so that it is also suitable for supporting workpieces with high weight.
  • the contact element has a polygonal cross section.
  • the contact element can optionally be fastened with at least two different side surfaces on the carrier element.
  • the contact element may have an at least partially rounded cross-section, by means of which a line contact is formed when a workpiece is placed.
  • the contact element may be either solid in cross-section or have a central recess.
  • the term "solid contact element” is to be understood as meaning that the contact element in cross section is either designed as a solid body or, preferably along its longitudinal axis, can have a hole or a recess. In the latter case, the contact element may be formed with respect to its cross section, for example in the form of a rectangle or a ring, with a central recess.
  • Essential for the contact element in the sense of the feature "solid” or in view of its cross-section is that its outer surfaces are sufficiently stable with a correspondingly high structural rigidity, so that the outer surfaces do not deform when a heavy workpiece or a large load and insofar form a stable and non-deformable bearing surface.
  • An essential aspect of the present invention is formed by the modular construction of the crimping component, namely in that at least one contact element can be mounted on the upper side of a carrier element and is exchangeable.
  • the bearing surface for a workpiece is not formed by the carrier element, but by an upper side of the at least one contact element. If the contact surface of this contact element is dirty or damaged, so alone the contact element can be exchanged inexpensively and with little effort, the frame member itself does not need to be replaced.
  • exchanging the contact element means that the contact element is replaced either as a whole and replaced by a new contact element, or that the same contact element is attached to the carrier element again after release from the carrier element, namely, that another side surface of this contact element, which is not dirty or damaged, forms the resulting bearing surface for a workpiece.
  • the replaceable contact element along the support member may be mounted in segments. This means that along the carrier element a plurality of individual contact elements can be provided, which together form a bearing surface for a workpiece. If there should be damage / contamination of a contact element in a specific region of the frame component, then a single contact element in the corresponding region of the frame component can be exchanged, wherein the contact elements adjacent thereto and not damaged or not contaminated can be left on the carrier element.
  • the attachment of a contact element at the top of the frame member can be done by screwing.
  • a through hole and in the top of the support member is provided a corresponding thread for a screw, or vice versa.
  • the head of a screw in the through hole of the Contact element arranged sunk so that does not protrude at the top of the contact element or the support surface for a workpiece.
  • a fastening of a contact element on the upper side of the carrier element can also take place by gluing, wherein this gluing point can be detached by applying a predetermined force.
  • the contact element in an advantageous embodiment of the invention may be provided on the upper side of the support member means with which the contact element can be arranged on the upper side of the support member in a predetermined position, namely expediently by positive engagement.
  • These means may be formed either as a web or as a groove, which is formed on the upper side of the carrier element and forms a contact surface for an end face or a side surface of the contact element.
  • the means for determining the position of the contact element on the upper side of the carrier element can also be designed in the form of a groove whose contour is adapted to a cross section of the contact element.
  • the width of the groove substantially corresponds to a width of the contact element.
  • the side surfaces, with which the contact element can be fastened on the carrier element in each case can be parallel to one another and opposite to one another.
  • the contact element has a rectangular cross-section, so that it optionally has at least two different side surfaces can be mounted on the top of the support element. These side surfaces of the contact element are opposite to each other. With a square cross-section of the contact element, it can optionally be attached to one of its four side surfaces on the upper side of the carrier element.
  • the optional attachment of the contact element with a certain side surface at the top of the support member has the advantage that in case of damage or contamination on a side surface of the contact element this component itself does not need to be replaced, this is due to the fact that the contact element then to his Longitudinal axis "rotated” and then re-attached to the top of the support member, so that a side surface of the contact element, which is not damaged or not dirty, is located at the top and thus serves as a new support surface for a workpiece.
  • the contact element may be mounted on the top of the support member such that at least on a side edge of the top of the support member and adjacent to the contact element, a defined contact area is formed for at least one additional frame member.
  • a modular worktable consists in the simplest case of a total of two frame members, which together define a virtual table surface with their respective longitudinal extent. Said abutment region on the side edge of the carrier element facilitates the assembly of an additional frame component, preferably in a direction transverse to the longitudinal extension of the original two frame components.
  • the virtual table surface of a modular work table is formed, for example, a total of four frame members, wherein two frame members are mounted in each case in a direction transverse to the longitudinal extension of the two other frame members, so that a total of a quadrangle is formed by the frame members.
  • a plurality of frame members are arranged parallel and spaced from each other. If in these frame members, a contact element respectively in the middle of the Top side of the support member, based on its width, is arranged, formed on the upper side of the support member on both sides of the contact element respectively defined contact areas, which are suitable for mounting for at least one additional frame member. Accordingly, it is possible to mount on a frame component according to the invention in a direction transverse to its longitudinal extension in each case an additional frame member which rests with its free ends on the defined contact areas. As a result, a modular work table can be formed, the total length of which can be arbitrarily adapted to a corresponding length of a workpiece.
  • a contact element has a longitudinal extent and is mounted with its longitudinal axis substantially parallel to the longitudinal axis of the carrier element on its upper side. As explained, this attachment of the contact element on the upper side of the carrier element can take place essentially in its middle, so that defined contact areas for additional frame components are formed on both sides adjacent to the contact element.
  • the length of a contact element can either correspond substantially to a length of the carrier element, or be shorter than the carrier element, wherein then along the carrier element a plurality of adjacent contact elements are provided.

  • the contact element can also be made of "softer" materials, for example of copper, aluminum, plastic or wood.
  • softer materials offer the advantage that workpieces Aufl. Depositing on the contact element against the formation of scratches or the like are protected on its surface.
  • the said alternative materials are cheaper than steel, especially in the case of plastic or wood.

  • An optimization of the contact element for practical use, in particular for carrying out welding work can additionally or alternatively be achieved by providing the side surfaces of the contact element, which optionally form the bearing surface for a workpiece, with a coating, e.g. An adhesion of welding beads difficult or prevented. Furthermore, such a coating can have a low sliding coefficient, so that a workpiece which rests on the contact element can be displaced thereon with little effort and in particular without damaging its surface. Such a coating can be formed using the plastic PTFE.
  • a workpiece is always stored or applied to the carrier element in the same place.
  • the contact element which is located on the carrier element at the point of application of the workpiece can be made of a "soft" material as explained above, in particular of plastic or wood. As a result, damage to the workpiece can be prevented.
