COMBINATION TOOL FOR CYCLE REPAIRS

Abstract: Combination tool for cycle repairs including a fitting tool (12) for removing and mounting tires (36) from or on a cycle felloe (37). The combination tool (10) is formed from a cylindrical sleeve (11) having a configuration such that it can readily be thrust on to one end of a cycle pump of the kind having at least one cylindrically shaped free end portion. The fitting tool is arranged at an end wall (13) of the sleeve (11) and comprises a tongue-like removing part (15) and a hook-like mounting part (16). Further auxiliary tools (23-27) are formed in the sleeve itself.

Description: Combination Tool for Cycle Repairs The present invention relates to a combination tool for cycle repairs, including a fitting tool for removing and replacing tires from and on to a cycle wheel felloe. If a person is to mend a cycle tyre puncture single-handedly, these are always required means for removing and mounting the tire from and on the felloe and a pump for inflating the inner tube, as well as the puncture repair kit including rubber patches etc. It is often also necessary to remove the wheel from the cycle, which normally cannot take place without the availability of a spanner for the nuts holding the wheel in place. In addition, other spanners and a screwdriver should be available for necessary removal and adjustment of different accessories on the cycle. Always carrying these tools results in certain dis¬ advantages , of course, which there have been attempts to reduce by producing special toolbags etc which can easily be attached to the cycle. However, only a few cyclists have equipped their cycles with such tool bags, inter alia due to the cost and the risk of theft. One object of the present invention is therefore to provide a combination tool for cycle repairs which can very readily accompany the cycle together with a conventional cycle pump. An other object is to enable all the operations necessary for mending a puncture with the sole use of the tool. A third object is to adapt the tool to such a cycle pump so that the latter can be used as a lever, and thereby improve certain of the tool's functions. Further objects and advantages of the invention will be apparent from the following description. They are achieved with the use of the distinguishing features disclosed in the following claims. The invention will now be described in more detail and with reference to the accompanying drawing sheet on which: Fig. 1 is a side view of a tool in accordance with the invention. Fig. 2 is a side view of the tool according to Fig. 1 but rotated 90°. Fig. 3 is a further side view of the tool accord- ing to Fig. 1 but rotated 180°. Fig. 4 is a plan of the tool in Fig. 1. Fig. 5 is a cross section along the line 5-5 in Fig. 1. Fig. 6 illustrates the tool according to Figs. 1 - 5 fitted to a cycle pump and in use during the removal of a tire from a cycle wheel felloe. Fig. 7 illustrates the tool being used in the same way but for mounting the tire on the felloe. The illustrated combination tool 10- includes a cylindrical carrying sleeve 11, there being a fitting tool 12 and further auxiliary tools formed integral with the sleeve. The sleeve has a circular cross section and has one end closed off with an end wall 13, its other end 14 being open. The fitting tool 12 includes a tongue-like removing part 15 and a hook¬ like mounting part 16, both parts merging into a common, flattened neck portion 17. This neck portion 17 departs from the end wall 13 in the longitudinal direction of the sleeve and merges into an extension curving somewhat away from the axis of the sleeve and forming the removing part 15. This has an outer end 18 which is rounded concavely inwards complementary to the frame tubes on ordinary cycles. The end 18 is furthermore provided with a support hole 19 for facilitating attachment of the combination tool 10 to the cycle frame, as will be described later. Correspond¬ ing holes 20 can optionally be made centrally in the fitting tool 12. The mounting part 16 is formed from a branch departing from the neck portion 17, this branch projecting right angularly from the neck portion with a first part 21, which continues into a second part 22 turned through a further 90 towards the end wall 13. Apart from the fitting tool 12, a plurality of further auxiliary tools can be carried on or formed in the sleeve 11. The illustrated embodiment thus has two hexagonal recesses 23, 24 arranged mutually opposing in the sleeve wall. The sizes of the recesses are selected such that they suit the most usual dimensions of wheel nuts on cycles. There are also two smaller slots 25, 26 made in the sleeve wall at the open end 14 thereof, one of these slots 25 being formed as a spoke tightener and the other 26 forming a spanner for some further nut dimension. Between the slots there is thus formed a toothlike part 27, and after being ground to shape this becomes an excellent screwdriver blade for slot-headed screws. A larger slot 28 is also suitably made along the sleeve from its open end 14 until at least half its length. Furthermore, an annular abutment 29 can be arranged inside the sleeve close to the end wall 13. The combination tool 10 is formed such that it can readily accompany the cycle together with an ordinary cycle pump of the type having a cylindrical part 30 with a nipple 31 at the end of it and a handle 32 joined to an unillustrated piston rod. More specifically, the inner diameter of the sleeve 11 has a somewhat greater diameter than the cylindrical part 30, so that the sleeve can be thrust over the bottom end of the pump. If the pump is of the kind having the nipple placed on the cylindrical wall, the larger slot 28 still enables the sleeve to be mounted on the pump end. Alternatively, the sleeve may be adapted for being thrust over the handle 32. The abut¬ ment 29 has the task of limiting the depth to which the pump can thrust on to the sleeve, so that a free space 33 is formed, and this space may be filled with suitable repair material, such as rubber patches etc. Location and storing of the pump with its tool fitted are simply arranged for by using the hook attachments on the cycle frame, these being of the kind normally engaging in the nipple 31 and a hole 34 in the handle. In this case, one of the attachments can engage in one of the support holes 19, 20. The concave end 18 of the - - removing part 15 also allows this end to be locked directly to a frame tube on the cycle, if so desired. In using the combination tool 10 for screwing screws, bolts etc, it is normally taken from the cycle pump first, but if the wheel bolts 35 are very tight for example, the pump can once again be thrust into the sleeve to form a suitable lever. It will be seen from Figs. 6 and 7 how the tool in its fitted position on the pump can be used for removing or mounting a tire 36 from or on a felloe 37. If the tire 36 is to be taken from the felloe 37, the rounded-off end 18 of the removing part 15 is thrust in under the tire between it and the felloe, the tire being first thrust away from the felloe rim with the thumb. The pump and tool 10 are then swung at the free end of the pump about 180 into the position illustrated in Fig. 6 so that the pump comes into engagement against the wheel hub 38 and project¬ ing shaft 39. With the aid of the support provided by the shaft 39, the pump and tool can now be pulled around the felloe, the part 15 easing off the tire as they are pulled around. When the pump has been pulled round about one complete revolution, one side of the tire has been completely removed from the felloe and the unillustrated inner tube can be removed entirely from the felloe, or the damaged part, e.g. a puncture, can be repaired, after which the inner tube is once again placed inside the tire. To fit the tire, the fitting tool 12 is located with its mounting part 16 between a portion of the tire that has already been placed by hand in the felloe and the felloe itself, as illustrated in Fig. 7. The cylindrical part of the pump, or possibly its handle, depending on the length of the pump in relation to the radius of the wheel, once again rests against the shaft 39 of the hub 38, and with the pump supported against the shaft, the pump and tool 10 are rotated round the felloe and tire, causing the tire to be eased over the fellow. When the pump and tool have been pushed about one complete revolution the tire is once again in its right place on the felloe and the inner tube can be inflated with the same pump which previously served as tire fitting tool. In summary, it may be established that the combination tool proposed in accordance with the invention enables anybody very easily to remove a cycle tire or the like for repairing a puncture or changing an inner tube. Removing or mounting a tire is done very quickly with the tool and cycle pump, and it is almost impossible to damage the inner tube in the process, this damage otherwise very often being a large problem. Practical tests have shown that it takes about 10 second to remove or mount the tire, this being a time which is of great interest, to some competition cyclists also. Since the tool is fitted to the pump, this also means that all the items are to hand which are required for such as mending a puncture. In addition, a plurality of further repairs and adjustments can be carried out since many different kinds of auxiliary tools are incorporated in the combination tool, and since its configuration enables it to be very easily attached to the cycle. Using modern die casting techniques, the tool can be manufactured very cheaply so that an equipment pack comprising tool, pump and repair material could be produced to a cost not greatly exceeding the cost of a conventional cycle pump.
