Definitions

  • the invention relates to a tensioning frame of a cleaning device to be provided with a textile covering, which has two clamping wings, one of which extends from a base part, which has a cardan joint for connection to a stem, on opposite sides, to be inserted into pockets or the like articulated and otherwise held by a spring catch.
  • Such a stenter is known from DE-OS 29 14 230.
  • the invention has for its object to make a stenter of this type usable to an expanded extent.
  • this purpose is achieved by that the articulated attachment of said one wing is arranged on a support which is displaceable in a guide formed on the base part and lockable in an extended and an inserted position, that the other tension wing is displaceable in a guide formed on the base part and in an extended position and an inserted position can be locked, and that the length of the two wings relative to the universal joint in the extended and the inserted positions is the same.
  • Such a clamping frame can be set to different lengths and thus allows, depending on requirements, to switch between different sizes of the cleaning device, to which clothing of different lengths belongs.
  • the guidance of the other tensioning wing mentioned can simply consist of a bend at the edges of the base part, which is expediently made of sheet metal.
  • the carrier could be performed in the same way as the wing. This would, however, be a division of the length available at the edges between the tensioning wing and the support, with the consequence of a correspondingly small displacement path or a holder that is too short.
  • the aim is to have guides that run the full length of the base part.
  • a particularly favorable design of the other tensioning wing in this respect, but also in general, is that of a U-shaped bracket. Between the legs of the bracket, which are held in the bends mentioned, there is space for the one tensioning wing, its support and its articulated attachment to the support.
  • the other support could also consist of a plate which has a cutout between the guides, so that it also sits with legs in the guides, between which there remains space for the support and the one tensioning wing mentioned.
  • other solutions would also be conceivable, for example space division in height with complete extension in width.
  • the bends for the legs of the U-shaped bracket form an approximately closed guide channel and, with a slot remaining at their end edge, form the guide for the carrier, which preferably consists of a flat plate.
  • the plate has space on the thickness of the end edge and a little further, also next to the legs of the bracket mentioned, so that the length of the guide can be fully available to both.
  • the guide channels have a height which accommodates the legs mentioned and additionally the engaging sections of the plate or the other support and the engaging ones Sections of the carrier extend essentially through the entire width of the guide channels. So there are two full guides in one, and in particular in the further embodiment that the legs are positively guided on their height section by a nose formed at its end and a height limitation formed at the end of the guide channels.
  • the engaging sections need only be short in the longitudinal direction of the guide channels.
  • Said one tensioning wing can supplement the holding force that is only required in the functional position of the tensioning frame, in that it rests in its resiliently latched position on the channel wall sections lying inside in the base part. They should only be short because the path of movement is limited by the noses mentioned.
  • the extended and the retracted position of the carrier are determined by cutouts in the channel wall sections lying inside in the base part, and the locking is achieved by means of the carrier reaching into the cutouts, preferably snapping under spring pressure, and attached to them Pull-out handles, bolts realized.
  • the cutouts are also end stops to which the wearer only needs to be pushed when adjusting.
  • the configuration is expediently and preferably carried out in such a way that the other tensioning wing mentioned is also locked in its inserted position by the bolts which extend beyond the incisions in the channel wall and into incisions in its legs.
  • the wing can and should have a stop at its end, which determines the position regardless of the incision. The function of the end stop will be mentioned below.
  • said other tensioning wing is locked in each case by seating the said lugs between the section of the carrier which engages in the guide channel and the bolt. So that the wing has an end stop even in the extended position, which will be discussed below. Otherwise this construction creates again the greatest possible displacement; in itself, an incision like the one already mentioned would be possible again.
  • said one wing which preferably also consists of a U-shaped bracket - in principle, a plate would be possible - can be pressed out of its resilient catch by a foot-operated articulated on the base part Lever arrangement, which lies with the shorter lever arm on the tensioning wing, such that when the foot is pressed onto the longer lever arm, the shorter lever arm lifts the base part from the latter while holding down the tensioning wing.
  • This lever arrangement can replace the device on the known clamping frame for releasing the resilient catch of the one clamping wing, which cannot be transferred to the new clamping frame.
  • FIG. 1 and 2 show a complete clamping frame 1 with two clamping wings attached to a base part 2 in the form of rectangular U-shaped brackets 3 and 4.
  • the bracket 4 is seated with its two legs 5 in guide channels 6 formed on the two edges of the base part 2 by bending the sheet, as can best be seen in FIG. 3 on the left and in FIG. 8.
  • the legs 5 do not occupy the full height of the guide channels 6. However, they are full in the bend, and the remaining height is bridged by an embossing 7 of the sheet at the end of the guide channel and an upwardly shaped nose 8 at the end of the leg (Fig. 8 right), so that the bracket 4 is still in the guide channels 6 is held positively.
  • the bracket 3 has the same width in its outer end region as the bracket 4. However, its legs 9 are cranked inwards and run in contact with the channel wall 10 until they are angled inward at the end and articulated at 11 on a plate 12 which represents a slidable support for the bracket 3.
  • the plate 12 drawn in FIGS. 9 and 10 is also guided in the guide channels 6, namely with the engagement of two laterally projecting sections 12 into the residual height already considered above the legs 5 and with the end edge 14 of the channel wall 10 as support and the outside duct wall 15 as a lateral boundary, see FIG. 3.
  • the plate 12 is displaceable. For this, however, the bracket 3 in its joints 11 must be folded out of the functional position shown.
  • leaf spring 16 In the functional position, its legs 9 are snapped onto a correspondingly shaped leaf spring 16, which presses them against the channel wall 10 and the plate 12. This is shown on the left in FIG. 3; as such, the leaf spring 16 does not appear in this section.
  • the leaf spring 16 extends on the underside of the base part 2 from one side to the other and is riveted to the base part 2 at 17 (FIG. 1). In the end position according to FIG. 4, the leaf spring 16 lies in the recess 17 of the plate 12 created for this.
  • a lever arrangement comprising a bracket 19 fastened in joints 18 to the base part 2 and a cross bar 20 fastened thereon and pressing on the legs 9. If pressure is exerted on the bracket 19 with the foot in accordance with arrow 21 in FIG. 2, the latter lifts the base part 2 at the joints 18 while holding the bracket 3 down over the crossbeam 20 and thus brings the leaf spring 16 out of engagement with the Thighs 9.
  • cutouts 30 and 31 are made at two points, through which the ends of the bolts 27 can pass in a latching manner.
  • the bolts 27 are engaged in the cutouts 31 and, moreover, each in an incision 32 in the legs 5, as shown on the right in FIG. 8.
  • Both brackets 3 and 4 are thus fixed relative to the base part 2.
  • the plate 12 also has an end stop on a fold 33 of the base part 2 (FIG. 2); the impressions 7 lie in two corner cutouts 35 of the plate 12.
  • the bracket 4 also has an end stop with the lugs 8 on small folds 34 of the base part 2 (FIG. 1 on the left).
  • brackets 3 and 4 are fixed relative to the base part 2.
  • the base part 2 is gripped with one hand when the bracket 3 is folded down.
  • the bolts 27 are pulled out of the cutouts 30 by gripping the two handles 26 between the finger and thumb of the other hand and 4 by pushing the plate 12 slightly to the right, the latter still by gripping the handles 26, brought into abutment with the channel wall 10. Then only the two brackets 3 and 4 need to be gripped with both hands and pressed towards each other. If the bracket 4 abuts the edges 34 with its lugs 8, the bolts 27 sliding along the channel wall 10 already find the incisions 32 when they arrive at the cutouts 31 and engage.
  • the bolts 27 first engage in the cutouts 31 and then butt them against the full cross section of the legs 5, they are nevertheless held in place by the thickness of the channel wall 10 and the bracket 4 moves further until it reaches its end position and the bolts 27 snap into place also in its incisions 32.
  • the handle In order to pull the stirrups out of the position according to FIGS. 1 and 2 and to bring them into the other position, the handle is first handled again as described, but the plate 12 is shifted somewhat to the other side, i.e. 1 to the left. Then touch the brackets 3 and 4 with both hands and pull the brackets apart. If the bolts 27 first snap into the cutouts 30, they remain held again, although they meet the full cross section of the legs 5. The bracket 4 then moves further up to the stop of its lugs 8 on the sections 13. Then the bolts 27 snap forward into their end position and the bracket 4 is held. If the lugs 8 meet the sections 13 first, it does not go on for the time being.
  • the base part 3 needs to be grasped and pulled further, the base part 2 moving over the brackets 3 and 4 no longer moving relative to one another until the bolts 27 in the cutouts 30 and now snap right behind the ends of the legs 5.
