Definitions

  • a support arm construction for a dental instrument table in which on a bottom-side vertical support tube (stand) a first and in turn a second horizontal support arm carrying the instrument table at its free end, each by means of a swivel joint are articulated.
  • Such a support arm construction can only be used in the intended arrangement, i.e. the support arm construction shown there with the base-side stand is not readily usable for ceiling mounting.
  • a support arm construction designed for ceiling mounting would not be readily usable for floor mounting.
  • the addition, omission or shortening of support tubes in the known construction is not possible or not possible without complex modification of the construction.
  • the invention specified in claim 1 is based on the object to provide an improved support arm construction. Due to the construction according to the invention of the support arm construction explained in more detail below, it is possible to put together an individual support arm construction with regard to the bends and support tubes to be provided and their lengths, using the same components in each case.
  • FIG. 1 shows a schematic representation of an embodiment of the support arm construction according to the invention for the pivotable mounting of a dental instrument table.
  • the support arm construction consists of a vertical support tube 2 fastened to a base-side stand 1, two horizontal support tubes 3 and 4 as well as pipe bends 5 to 8 for connecting the support tubes to one another or to the instrument table 9. ...._._.._. ..,
  • the support arm construction is provided for ceiling mounting and for this purpose also contains a vertical support pipe 2 'and a pipe bend 5' which is offset by 180 ° with respect to the previously explained arrangement.
  • the support arms 3 and 4 can be pivoted at the points shown by arrows, otherwise the parts are rigid, i.e. non-rotating, connected to each other.
  • an additional height-adjustable support arm can be provided, or the support arm designated by 4 can be designed as a parallelogram support arm.
  • the support tubes 2, 3, 4 have a constant profile, preferably extending over their entire length, which, as will be explained in more detail later, fits a correspondingly designed counter profile on the tube bends 5 to 8, so that a rotationally fixed connection between the pipe bend and the support pipe can be established by axially plugging together.
  • the profile is designed in such a way that the pipe bend can alternatively preferably be used offset by 180 ° with respect to the support tube, so that, as shown in dashed lines in FIG .
  • the profile of the support tubes is shown in Figure 2.
  • the pipe bend consists of a base body 13 (blank), which has a plug pin 14 at one end and a bore 15 at its other end for receiving a pivot pin of a further pipe bend adjoining it (e.g. pipe bend 6).
  • the pivot is axially secured by means of an angle plate 25 screwed onto the base body 13.
  • the plug pin 14 is provided with a counter profile matching the profile according to FIG. on the spigot 14 there are also on the one hand four evenly distributed longitudinal grooves 16 that fit the elevations 11 of the support tube profile, and intermediate webs 17 that match the longitudinal grooves 12 of the support tube profile.
  • connection of the pipe bend 5 or 5 'to the vertical support pipe 2 or 2' is explained in more detail with reference to FIGS. 9 and 10.
  • This connection is a rotatable connection, i.e. the pipe bend can be rotated around 360 ° around the support pipe.
  • Such a connection can also exist between the arch 7 and the arch 6.
  • a pipe 26 protruding in the form of a pin is screwed or otherwise fastened into the bore 15 according to FIG.
  • a plastic bushing 27 is placed thereon and axially secured by means of washer 28 and spring ring 29.
  • the plastic bushing 27 together with the tube 26 forms a slide bearing, i.e. the socket is freely rotatable relative to the tube 26.
  • circumferentially arranged locking elements are designated, which correspond in profile to the profile of the pin 14 at the other end of the bend, so that they match the tubular profile shown in FIG. As shown in FIG.
  • the tube contains a recess or undercut 31, the depth of which corresponds to that of the latching elements 30, so that when tube 2 and bend 5 are joined together, the parts are inserted axially via the recesses 12 and after the two parts are rotated Bayonet-like connection is created, which absorbs the axial forces when suspended.
  • a set screw 32 can be provided in the support tube 2, which engages in a thread or in a blind hole 33 in the plastic bushing 27 and thus prevents the bayonet connection from being unscrewed.
  • the turning range can be limited to a maximum of 360 °, e.g. in the form of a stop pin or the like. Be present, which are then attached at the point marked 34 in the support tube and at a corresponding point in the tube 26.
