ADDITIONAL MACHINE DEVICE FOR THE TUBULAR ATTACHMENT FOR A VACUUM HOSE

The invention relates to an additional retaining device for a tubular fitting which is connected to a vacuum cleaner hose. Under normal circumstances, the tubular bulge is held with two hands during vacuum cleaning and a forward and reverse movement is made on the vacuum cleaner nozzle. In addition, one band is usually at the top and the other band below it. Due to the resistance encountered during the vacuuming operation, it is often not possible to operate the tubular joint, for example, only to operate the 64n belt, i.e. to sweep forwards and forwards. Due to the unequal working height of both hands, this leads to a half-bent posture and in that posture one soon experiences back pain, which applies to people tall and small, but certainly for people who already have back problems. So far, this incorrect posture has not been met by taking measures that adjust the operating angle for both belts to the users.

The object of the invention is to provide a useful solution by applying "human engineering" to the problem which has been found to exist. It consists of a strap grip which is located on the end of a separate binder attached to or on said pad, the strap grip of which extends substantially on the same operating arc as that on which the usual fixed portion for the top other strap of the user extends near the end of the flexible vacuum cleaner hose, the former strap handle occupying a position some distance from this fixed portion.

In connection with the fact that the tubular bulge is also used in positions in which the user is not standing, it is desirable, inter alia, not to cause the additional securing device in such situations to be an obstacle. According to the invention it is therefore advantageous to use the strap with strap grip by means of coupling members easily detachable with respect to the joint. Such advantages are also obtained if the holder is rotatably mounted with respect to the or the coupling members and the obstacle can furthermore be retracted as far as possible within the acceptable range if the strap grip can be collapsed respectively with respect to its attachment on or to the fitting and can be locked in έ6η or both positions.

The additional fastening device according to the invention is used as a separate part for tubular shoulder pieces of unequal diameter than 8104552. ir '* rt' * ϊ! * '··> - *' · * · - '* ·' * - ~? · * · - * “<* '* - · .. ·· *' '** · <· »· J '·· * · i. The invention provides for this in that a rod-shaped holder with its part to be coupled to the attachment opens into an elongated, for instance partly cylindrical, bearing surface. the two or two ends of which are locked on the auxiliary piece by means of an annular clamping member.

In order to obtain a good power transmission from the handle on the holder to the intermediate piece, in another embodiment the coupling between both can be ensured by means of a snap-in coupling in cooperation with a stop member, either on the fitting or on the device, respectively. .

If the shape of the attachment permits, it can be advantageous. to use as a coupling member a short tube-shaped member on which the holder with handle is mounted, which is slid over the fitting on the spot and secured by means of known tube-connecting means.

The invention will be explained below with the aid of the token, on the basis of a few exemplary embodiments.

For simplicity, Fig. 1 shows a flexible vacuum cleaner hose 1 which terminates in a connecting piece 2 of slightly curved shape, which can be suitably connected to a tube-shaped fitting usually consisting of two parts that can be slid together. When vacuuming, both hands of the user (star) are placed at a distance from each other and it may be assumed that the posture forced by this is known. some time it becomes very tiring due to the semi-stooped position that the user always has to take.

In Figs. 1 and 2, schematically according to the invention, the additional holding device is shown in dotted lines, with which a normal working posture can be maintained because now both hands are at the same working height, έέη on the connecting piece 2, the other for side at any distance from the handle 6 located on the end of the operating arm S. The aforementioned drawbacks are now completely eliminated and the advantage also arises that the exertion of force, e.g. when vacuuming deep pile carpet using a brush nozzle, much more favorable than when the predominantly downward rather than horizontal pressure is generated by the usual hand in the lowest position on the attachment. In h. 1 the hand height is indicated for one hand. H '' shows the usual hand height for the other hand. In Fig. 2, according to the invention, the hand height for both hands is indicated with h. The holding device 15 according to Fig. 3 shows its attachment to a vacuum cleaner tube 3. A cylindrical thin-walled tube piece 7 has an inner diameter which is slightly larger than the outside diameter of the tube 3. The tube piece 7 is provided at one end over a certain height of external screw thread 8 and this screw thread cooperates with an annular nut 9 which is provided with corresponding internal screw thread 10. This nut 9 has a cylindrical inner edge 11 of which the internal diameter is slightly larger π * ™ the external diameter of the pipe 3 but is sufficiently wide to form a pressing surface for the mating surface 12 of a conical ring 13. The gap-shaped tolerance between pipe 3 and the pipe piece 7 slid over it is such that the ring 12 in cross-section can be fixed therebetween v. the nut 9. If the pipe 3 is now slid into the pipe piece 7 and then the conical ring 13 is placed in the slit-shaped space between them, the annular nut 9 can then be screwed onto the screw thread 8. As a result, the conical ring 30 13 , made of flexible plastic, pressed into the slit-shaped space, whereby the pipe piece 7 is coupled unalterably to the pipe 3 at the desired height. A hollow operating arm 5 is soldered or otherwise mounted on the pipe piece 7 in its longitudinal direction and then bent outwards sideways; at its end, the operating arm 35 is provided with a handle 6. By means of this handle 6 can now be exerted additional force at almost the same working height by both hands, which excludes the drawbacks mentioned. In Figs. 4 to 8 a few other embodiments for the application of the invention are shown.

In fig. 4 there is a hinged coupling 14 between pipe piece 7 '40 and the bottom end of the operating arm 5'. The coupling thereby comes to 8104552 £ - 4 - position by means of a bolt 15. In fig. 5 the same hinged coupling 14 is shown with a clamp 16 with which the operating arm 5 '' can be held against the pipe piece 7 '. In Fig. 6 the holding device consists of a cylindrically bent plate piece 17 on which two ears IS are located which, by means of a bolted connection forms the articulated coupling with the control arm. Since ribs (not shown) are formed on the plate piece 17, its attachment to the tubular fitting 3 can for instance take place by sliding on elastic plastic rings 19, whereby the force exerted by the operating arm is fully absorbed. In Fig. 7, the holding device according to the invention is designed as a semi-cylindrical tube part 20 to which the operating arm is attached. The metal fitting 3 'is now provided with a welded eye 21 into which the narrowing lower end 22 is slid, after which the pipe part 20 connects around the fitting 3' by snap action. In Fig. 8, a simple clamping connection between the attachment and the operating arm is chosen, which does not require further explanation. The coupling members 23 and 24 exhibit an opposite position to the operating arm, so that the application of force is favorable by means of establishes the confirmation.

When applying the invention it may furthermore make sense to provide the contact surfaces between the attachment and the operating arm / coupling members with anti-slip material and / or with anti-slip ridges, as indicated by 25 in Fig. 7. In Figs. 4-8 the fittings are only partly drawn to the extent necessary for proper understanding. For the fig.

4 and 5, the same type of fastening of the holding device is shown as described in more detail in Fig. 3. The hinged coupling 14 consists of an ear on the pipe section 7 and a yoke-shaped lower end on the operating arm 5 ', the construction of which is assumed to be known per se. The clamp 16 in fig. 5 can be spot welding or the like can be connected to the pipe section. In Fig. 6, the curved plate piece 17 is further chamfered at both ends in order to facilitate the application of the two plastic rings 19. Because the mounting location of the pipe section 7 can be adjusted in relation to the desired working height, the holding device can be optimally adjusted for each user (star).

The operating arm schematically drawn in fig. 8 can, for example, be spot welding on the coupling members 23, 24 is attached. The choice of material for the holding device depends on the fittings to be used. In practice, metal and plastic pipes 3 are used. A metal tube can be used in combination with a plastic holding device, but metal / metal or plastic / plastic is also possible.
