Definitions

  • the invention relates to a device for holding a dental handpiece, to which a supply hose is connected which, when the handpiece is placed below the shelf, sags freely downward like a loop.
  • a disadvantage of retractable supply hoses is that the return devices provided in the form of special hose drums, swivel levers with various deflecting rollers, etc. are technically relatively complex and, moreover, are not maintenance and wear-free.
  • Another disadvantage is the fact that the restoring torque emanating from the restoring devices re must be of a relatively large size so that the hose can be returned to the housing when not in use. This relatively large restoring moment, which loads the handpiece when it is removed and is disruptive to the practitioner, must be intercepted by an additional latching device. This means an additional technical effort, is prone to failure and not exactly user-friendly.
  • the holder of the handpieces with freely sagging supply hoses has the essential advantage over the retractable hoses of a considerably simpler construction of the entire hose train, furthermore that no maintenance of return and locking devices is required and that no disturbing restoring torque is to be overcome when pulling out the hose.
  • a disadvantage of such holders is that the handpieces have to be inserted specifically into the storage spouts, which are generally designed as slotted rings that are open at the bottom, so that the handpiece cannot be "blindly" replaced.
  • the invention specified in claims 1 and 9 is based on the object of specifying a device of the type mentioned at the outset, that is to say with loops hanging freely downward in the deposited state, in which one possibility is possible with relatively little technical effort and largely maintenance and wear-free it is given to achieve the advantages of the known arrangements provided with additional complicated return devices, ie to enable a "blind" return of the handpieces and their supply hoses.
  • the role over which the hose is guided, together with the counter member which can be a bracket or one or more counter roles, has the function of a handpiece rest; it also serves as a holding element for the pulled-out hose in order to enable a continuous work with the handpiece, largely free of restoring forces.
  • the supply hose which already has a certain self-stretching property, is additionally provided with a resilient core arranged in an empty channel, which ensures a uniformly neutral sagging of the hose in the non-use position and also supports the necessary return of the hose.
  • a resilient core inserted in the supply hose, in connection with a storage sleeve, which, at least in the area of the hose guide, can expediently be made entirely of a material with good sliding properties, e.g. made of PTFE, create an even simpler device.
  • a flexible shaft shaft core
  • a spring-elastic core Due to the weight of the hose, the additional weight of the inserted core and the restoring moment from the resilient core, a practically torque-balanced placement of the handpiece can be achieved with the further advantage that practically no detent is required.
  • FIG. 1 shows a highly simplified diagrammatic illustration of a dental device with a housing 1 in which three handpieces 2, 2a, 2b are held.
  • the handpieces are arranged next to one another at an excessive distance. With practical arrangement, the distance would be considerably closer, so that at least five or six handpieces could be arranged with the same housing width.
  • the device for holding the handpieces is the same for all three handpieces and is explained in more detail using the example of the handpiece 2.
  • a hose guide roller 4 For holding the handpiece 2 and for guiding the associated supply hose 3, which, when the handpiece is put down, sags freely downward and into a connection box of the Ge, not specified housing 1 opens, on the one hand is a hose guide roller 4, over the tread 5 (groove) of the hose 3 rolls when removed, and on the other hand a bracket 6 is provided, which prevents the hose 3 from jumping off the tread or groove 5 and on the other hand together forms a stop with the guide roller 4 and a holder for the hose-side end of the handpiece 2, designated 7.
  • the hose guide roller 4 can be freely rotated freely about an axis 8, the rotatability being suitably adjusted by suitable friction elements.
  • the bracket 6 is provided with a spoon-shaped extension 9, which, as can be seen from the illustration of the handpiece 2b, serves, as an alternative to the storage, as shown for the handpieces 2, 2a, to be able to deposit the handpiece in such a way that it with the handle part rests on the spoon-shaped extension.
  • Bracket 6 and extension 9 are bent from wire in a particularly simple embodiment.
  • FIG. 2 shows an embodiment in which only the lower part 10 is bent from wire and a counter roller 12 mounted on a holder 11 is provided as a counterpart to the guide roller 4.
  • the guide roller and counter roller 12 serve simultaneously as a stop and Bracket for the hose-side end of the handpiece.
  • the distance between the two rollers 4 and 12 is so dimensioned that on the one hand the hose 3 can slide easily through the opening formed together with the holder 11, on the other hand the handpiece end 7, which is larger in diameter than the hose, is fixed.
  • the bracket 10 with the bracket 11 is also adjustable in the inclined position so that the storage angle for the handpiece can be adjusted individually.
  • the first handpiece rest given by the guide roller 4 and the stirrup 6 or counter roller 12 and the second handpiece rest given by the extension 9 offer the possibility of different staggering of the individual instruments in the case of several holding devices lined up next to one another. As a result, the accessibility for the practitioner can be improved, particularly when the individual instruments are arranged in a very dense and compact manner.
  • a separate adjustment option can also be provided, i.e. the upper and lower shelves can be adjusted separately.
  • the hose itself can be a multi-channel hose with various channels 13 for guiding various media (air, water) and in the center with an empty channel 14 in which a resilient core 15 is guided.
  • a spring-elastic core 15 a shaft core or flexible shaft (biax shaft), which was previously used exclusively for torque transmission, is advantageously used, in which two or more springs, possibly with the insertion of a longitudinal core, are wound in opposite directions.
  • the resilient core 15 can extend over the entire length of the hose; In order to improve the manipulability with the handpiece, the resilient core only runs close to the hose end adjacent to the handpiece.
  • FIG. 4 shows a further variant of a supply hose, in which the media channels are arranged like a shamrock around a centrally arranged empty channel 14, in which a resilient core 15 runs.
  • the cloverleaf-like multi-channel hose can be brought in a known manner through a suitable sheath 16 to an optically almost circular cross-section. The latter may be desirable from a hygienic point of view in order to be able to perform a better cleaning of the hose.
  • the resilient soul can also be in one of the other, formed by the envelope Cavities or channels can be arranged.
  • the empty channel does not necessarily have to be an unused media channel, rather it can be formed by appropriate shaping of the hose cross section.
  • the use of the resilient core inserted in the supply hose enables a particularly simple mounting in connection with a sleeve-shaped handpiece holder, as shown in part in longitudinal section in FIG is.
  • the handpiece 2c is held in a receiving sleeve 17 which is pivotally supported by means of an axle bearing 18 in a housing 19, which is constructed similarly to the housing 1 in FIG. 1 and can carry the necessary supply components inside.
  • the handpiece can thus be brought into different swivel positions in a certain angular range ( ⁇ ).
  • the storage sleeve 17 is made of a material with particularly good sliding properties, for example made of PTFE, and is strongly rounded at the end 20 facing the hose, so that there are no frictional edges braking when the hose is pulled out and run in lie.
  • the spring-elastic core inserted in the hose causes the hose to sag in any position and provides the necessary restoring moment when the hose is pulled out.
