Definitions

• the invention relates to a flexible hose for supplying and / or discharging a pneumatic pressure medium required for operating a working device, e.g. Suction hose for the dust extraction of a woodworking device.
• a working device e.g. Suction hose for the dust extraction of a woodworking device.
• the hose mentioned above is used in particular in suction devices and other devices with dust extraction. It is connected to one of its two axial ends on the suction device, which generates a negative pressure inside the hose during operation, so that dirt or dust particles can be sucked in via the other, free end of the hose.
• This mode of action is often used in woodworking by connecting the free end of the hose to a suction device of a woodworking device in order to produce chips or the like. vacuum in the area of their occurrence and keep them away from the environment.
• the woodworking machine now has an additional supply line, an electrical connection cable, for the power supply.
• the above object is achieved in that on the outer circumference of the hose at least one holder for fastening at least one supply line leading to the implement, for example in the form of an electrical connection cable, a compressed air hose or the like. is arranged and that / at least one holder is integrally formed with the hose.
• all the leads leading to the implement, including the flexible hose itself can now be combined into a single feed line.
• This strand has relatively small and compact radial dimensions, so that the handling is not deteriorated compared to known hoses of the type mentioned. At the same time, the Flexibility of the hose is not affected.
• the guidance in a common strand prevents the supply lines and the flexible hose from forming a tangle that is detrimental to proper work. Even in difficult working positions of the implement, the supply lines are organized and clear. This has the further advantage that accidental damage to the supply lines is excluded; there is no longer any danger that the supply lines may get into the working area of the implement connected to the hose.
• the hose according to the invention can be produced inexpensively, since the holder can already be molded onto the hose during manufacture.
• the brackets are preferably made of the same material as the hose.
• Another advantage of the invention is that it is possible to manufacture the hose in so-called yard goods, which again significantly reduces the production costs.
• the desired hose length can be determined by simply cutting to length after hose production.
• the development according to claim 2 has the advantage that the hose is not tied to a single and specific implement. When changing the implement, the leads can simply be removed from the holder and the leads of the device currently in use can be attached instead.
• the development according to claim 3 combines the possibility of a secure attachment of the supply lines to the hose with the guarantee of optimal flexibility of the hose. The successive arrangement of the brackets leaves enough room for the hose to be bent into all the required positions.
• the developments according to claims 6 to 8 enable simple attachment and detachment of the feed line (s) to the hose according to the invention.
• the holder is advantageously designed to be flexible, so that even several feed lines can be attached to each holder at the same time. This is particularly advantageous if the implement connected to the hose has, for example, additional hoses for supplying or removing compressed air.
• the development according to claim 3 also allows quick replacement, ie loosening and fastening, of the feed lines.
• a supply line is attached to the bracket simply by latching or clipping into the bracket, which is provided with flexible, resilient and resilient bracket walls.
• FIG. 1 is a side view of a first embodiment of the hose according to the invention
• Fig. 2 shows a section through the hose of Fig. 1 along the line II-II and
• FIG. 3 shows an enlarged section of the hose according to III from FIG. 1.
• the flexible hose 1 serves to supply and / or discharge a pneumatic pressure medium required for operating a working device. His preferred application is in the field of dust extraction in the field of woodworking.
• one end of the hose 1 is connected to a dust extraction device, for example a vacuum cleaner, while the other end of the hose is fixed to the suction nozzle of the suction device of a woodworking device. If woodworking is carried out, the chips or dust accumulating in the working area of the woodworking device can be suctioned off via the flexible hose 1, so that the pollution of the environment and the operating personnel is reduced to a very great extent.
• the flexibility of the hose according to the invention is advantageous for unhindered mobility of the implement.
• the hose 1 according to the invention has a rib-shaped outer contour and is provided on its outer surface 3 with a plurality of circumferential ribs 2 arranged one after the other in the hose longitudinal direction.
• the circumferential ribs are ring-shaped and have an approximately rectangular cross section; Between the individual successive circumferential ribs 2 there is in each case an annular gap 4, the width of which measured in the longitudinal direction of the hose 1 corresponds approximately to the width of a circumferential rib 2.
• the circumferential ribs 2 are part of the wall 5 of the hose 1, which is particularly illustrated in FIG. 3. Accordingly, the wall 5 of the hose 1 has a meandering structure, seen in the longitudinal direction of the hose, which is created by the fact that the ribs 2 each have a circumference from the inside 6 of the hose 1 slot 7.
• the circumferential slots 7 are widened when the hose 1 is bent in the region of the outer radius of curvature, so that there is practically an extension of the hose 1, which justifies its flexibility.
• the holder 11 for fastening at least one feed line 12 leading to the implement connected to the hose is arranged on the outer circumference 10 of the hose 1.
• the holder 11 has two holder walls 14, 14 ′ which are opposite one another to form a receiving gap 13. These are integrally formed on the hose 1 and protrude from the outer surface 10 of the hose 1.
• the two mounting walls 14, 14 ' are expediently formed symmetrically to one another and are arranged at a distance on both sides of the plane of symmetry defined by a diametrical plane 1-5.
• the holder walls 14 run parallel to the longitudinal direction of the hose and extend almost over the entire axial length of the hose 1.
• the holder 11 ends in each case one amount before the two axial ends of the hose 1, so that a kink-free routing of the supply line 12 from the holder is possible.
• the holder walls 14, 14 ′ are designed in the form of strips and are molded with one of their longitudinal edges 16 onto the outer surface 3 of the hose 1.
• the longitudinal edges 17 of the holder walls 14, 14 'pointing away from the hose 1 are bent towards one another and laterally delimit a slot-shaped holder opening 18, the length of which corresponds to the length of the holder walls 14, 14'.
• the distance between the two holder walls 14, 14 'in the region of the holder opening 18 which runs in the longitudinal direction of the hose and connects the receiving gap 13 to the surroundings, i.e. the width of the holder opening 18 is less than the distance between the two holder walls 14, 14 'in the non-bent region of the receiving gap 13.
• the described embodiment of the holder 11 makes it possible to arrange a feed line 12 between the two holder walls 14, 14', the diameter of which expediently corresponds approximately to the distance between the two mounting walls 14, 14 'in the area not bent.
• the bent longitudinal edges 17 encompass the feed line 12 over part of its circumference, so that the feed line 12 is secured against radial slipping out of the holder 11.
• the holder 11 enables the supply line 12 to be fastened in the context of a clip-in or. Latching process.
• the supply line 12 for fastening in the holder 11 only has to be attached to the holder opening 18 and under radial pressure towards the inside of the hose into the opening take gap 13 are pressed.
• the bracket opening 18 expands by flexible "springing apart" of the two bracket walls 14, 14 ', which are expediently made of flexible and in particular plastic material.

• the circumferential length of the gap corresponds to the width of the holder 11 measured transversely to the longitudinal direction of the hose.
• All the gaps 22 of the circumferential ribs 2 are arranged linearly one after the other, so that practically a channel is formed in which the holder 11 is seated.
• the free ends 23 of the ribs 2 formed by the gaps 22 lie against the outside of the mounting walls 14, 14 ′ and support them in order to support their clamping force exerted on the received feed line 12.
• the hose according to the invention can advantageously be manufactured in the form of yard goods, the holder 11 being molded on at the same time. After the manufacturing process, the bracket 11 covers the entire length of the cunning
• the free ends 23 of the circumferential ribs 2 are preferably not connected to the mounting walls 14, 14 'in order not to impair the flexibility of the hose 1 too much.
