Abstract

1420622 Wheel rims AVON RUBBER CO Ltd 1 May 1973 [2 May 1972 6 Nov 1972] 20397/72 and 51069/72 Heading B7C A wheel rim assembly comprises a wheel rim 1 having a well 8, an obstructor 11 for preventing the beads of a tyre entering the well in the event of tyre deflation and means for retaining the obstructor in the well. The obstructor may have the form of a band, the ends of which are releasably secured together by radially or tangentially disposed screws (see Figs. 1, 9a and. 10a). In the Fig. 6 assembly, screwthreaded member 47 releasably securing the ends of the band is also the body of an inflation valve, and when in the illustrated position prevents axial inward movement of a tyre bead seated adjacent flange 39. Radial outwardly directed projections (30, 31) (Fig. 4, not shown) axially inward of the tyre bead seats hinder axially inward movement of those beads when the tyre is deflated. The rim assembly is preferably used with a tyre having an aspect ratio of 60% or less. After mounting the tyre, in the conventional manner, on the rim the well is exposed, the obstructor is secured in the wall, and the tyre is then inflated. The obstructor may be such as to fully occupy the well. [GB1420622A]

Claims (6)

Claims 1. The rim of a wheel adapted to be mounted on a non-touchless tire, having a radially protruding flange on each of its side edges, and at each flange formed conical sections, adapted to place the tire feet on them, the rim having a groove extending radially inward, extending around the circumference of the rim and located between the tapered sections, in which cavity is a valve adapted to pump air into the tire through holes made in the resistor, characterized in that it comprises a resistor (11, 24, 41, 60, 63, 68) formed of metal tape, enabling access to the indentation (8, 25, 44) from the conical sections (5), with this resistor surrounding the indentation along its entire circumference and adjacent to the base part (2, 22, 42) and the conical section (5) the rim and, moreover, the resistor (11, 24, 41, 60, 63, 68) comprises screws (17, 47, 61, 66) securing the resistor against circumferential displacement. 2. The rim of a wheel according to claim 1, characterized in that the screw (17, 61) is located radially in relation to the rim and its head rests against one end (16) of the resistor, and the nut (19, 62) is screwed onto the rim. this screw rests against the other end (14) of the resistor and connects it radially to each other. 3. The rim of the wheel according to claim 1, with the fact that the screw (66) is located tangentially to the rim and rests its head against one of the ends of the resistor (68) and the nut screwed onto this screw rests against the other end of the resistor, joining the ends (64 * .65L6fL70) tangentially team. 4. The rim of the wheel according to claim The method of claim 1, characterized in that in the side walls of the cavity (25) embossing rings (35) are made in which the edges of the resistor (24) are placed. 5. A wheel rim according to claim 1, - characterized in that a projection (31) is provided between the conical section (23,27) with the indentation (25) near the flange (26). A rim according to Claim 1, characterized in that a second projection (30) is located at the second flange (36). 87,077 E / gJ.
