Definitions

  • Valve having a cap arrangement for wheels, tyres and tubes
  • the invention relates to a valve having a cap arrangement for wheels, tyres and tubes intended for mounting on a wheel rim, especially for motor cars as stated in the preamble of claim 1.
  • the invention further relates to a cap arrangement for a valve.
  • passenger cars are usually equipped with tubeless tires where the valve is mounted in the wheel rim, but tyres having an inlaid tube with a valve also exist where the latter type is especially used for large vehicles such as busses and trucks.
  • the valve consists of a tubular valve body of metal, typically having an outer rubber jacket which extends into the tyre or the tube. The outermost part of the metallic valve body is freely exposed without rubber jacket.
  • the entrance opening of the valve body is closed by means of a cap arrangement, which extends downwards over the valve body.
  • the securing means for the cap arrangement consist of threads, where the cap arrangement is furnished with a first thread internally in its hollow while the valve body on the outside and at least over a distance at the free end has a second thread cooperating with the thread of the cap arrangement for securing the cap arrangement on the valve.
  • the cap is located in a dirty environment with brake dust, road dust, small particles, water, snow, ice and salt which forms a layer on the valve and moreover may partially get into the valve at the edge between the cap and the valve.
  • the cap is intended for unscrewing with the fingers and may due to the environment in which it is located more or less be stuck on the valve, so that it can be difficult to loosen, especially due to the fact that there is usually very little space around the valve so that it can be difficult to get a good grip around the cap. Furthermore unscrewing of the cap will get the hands very dirty and they can afterwards be very difficult to clean.
  • the purpose of the invention is to provide a simplified construction which may also be used in connection with types of valves where the tubular metallic valve body is coated with rubber.
  • the mutually cooperating securing means are designed as a snap-lock connection, where the first part of the snap- lock connection is constructed in the cap arrangement, while the other part is constructed directly on the valve.
  • a snap-lock connection avoids having to screw off the cap; instead it may immediately be pulled off in one movement .
  • US 1 421 117 discloses a cap arrangement for valves for car tyre tubes, where the metallic tubular valve body is exposed without rubber coating and having external threads in its entire length and protrudes through a hole in the wheel rim.
  • This cap arrangement comprises a mounting part consisting of a nut and cone designed as one piece, said cone having a slanting edge in the passage between the nut and cone.
  • the mounting part has a central hole so that the nut may be screwed over the tubular portion of the valve against the wheel rim for fixing the valve.
  • the cap arrangement further comprises a cylindrical cap which may be placed axially over the tubular portion of the valve and be secured to the cone of the mounting part in a snap-lock connection as the cylindrical part in the opening has an inwardly bent wall part, which reaches under the slanting edge between the nut and cone of the cap arrangement.
  • this cap arrangement consists of two separate parts, with the condition that the mounting part may be screwed all the way over the tubular valve body in fixed engagement with the wheel rim.
  • valve cap and the valve may be constructed in various ways, where one possibility is as a mutually cooperating collar and recess.
  • the cap arrangement may be secured to the valve by means of a strap to ensure that the cap arrangement will not go missing.
  • claim 10 discloses a cap arrangement designed as stated in one or more or the claims 1-9.
  • the summer tyres are marked e.g. with a pen, RF for right front wheel etc., before the tyres are placed in storage.
  • the marking with a pen is problematic as the tyres and wheel rim are usually rather dirty, causing the marking to become indistinct.
  • the cap arrangement is equipped with an identification tag with an indication of where on the car the tyre should be mounted.
  • the valve is immediately visible oft the tyre, but is still located in a relatively protected area, so the identification will in any case be easy to localize and may still be designed so that it is easily readable.
  • the identification tag is an integrated part of the cap arrangement, which ensures an uninterrupted connection between the wheel in question and the indication of its position on the car.
  • the identification tag may however also be designed as a separate part, which may be mounted in connection with the cap arrangement. This could e.g. be a brick-shaped element secured to the cap arrangement/valve .
  • the indication of the position on the car where the tyre should be mounted may be carried out in various ways, but expediently a stamping is used, which is long-lasting. It is of course also possible to use a color coding or a letter coding e.g. RF for right front wheel and so on.
  • the identification tag has four stampings located in a square indicating the position of the tyres and where the stamping of the tyre at hand differs from the other stampings preferably in that it is larger than the others.
  • the stamping of the tyre at hand may be a circular arc while the others may be flat.

  • the cap arrangement is cylindrical with an exterior which on the whole corresponds to the rubber jacket 3 on the valve body. This is however not a requirement and the exterior of the cap arrangement does not necessarily have to be circular.
  • Figs. 4 and 4a of the drawing thus disclose an embodiment where the cylindrical part 6 is cone-shaped with an oval cross-section and where the largest cross-section is at the opening 12 of the cylindrical part of the cap arrangement. The largest diameter of the oval cross- section is moreover larger than the diameter of the rubber jacket 3 of the valve, causing the valve arrangement with its lower part to protrude outside the rubber jacket 3 on the valve.
