[0141] The fourth pair of hook-shaped (or dovetail-shaped) sliding connection portions 46 are arranged in such a way that their sliding direction is perpendicular to the sliding direction of the third pair of hook-shaped (or dovetail-shaped) sliding connection portions 41.

[0142] The fourth pair of hook-shaped (or dovetail-shaped) sliding connection portions 46 can be arranged to define, between them, a surface concavity, or a surface convexity.

[0143] In the specific embodiment shown in the attached figures, the fourth pair of hook-shaped (or dovetail-shaped) sliding connection portions 46 of side connection area 45 are arranged to define, between them, a surface convexity.

[0144] The fourth pair of hook-shaped (or dovetail-shaped) sliding connection portions 46 of side connection area 45 includes two lips 47 and two grooves 48, facing outwards.

[0145] As shown in FIG. 16, a simple and strong slideable connection is achieved between container 40 and body 90 of second multi-tool assembly 60.

[0146] To operate the chainbreaker 62, one of the tool bits 180 of the first multi-tool assembly 130 is pivoted out, and it is inserted in the hexagonal key socket 122 of first screw pin 120.

[0147] The sliding connection portions 291, 91, 92, 41, 46 allows extremely easy connection between the components of the tool storage assembly 10, a secure connection during storage, and easy separation once removed from storage.

[0148] FIG. 12 shows an alternative embodiment of the invention, wherein the tool storage assembly 10 only includes the container assembly 20 and the first multi-tool assembly 130, directly connected to each other.

[0149] In a further embodiment of the invention, not shown in the figures, the tool storage assembly 10 could include the container assembly 20 and the second multi-tool assembly 60, directly connected to each other.

[0150] According to a further aspect of the invention, a head tube assembly 400 is disclosed (FIGS. 17-28).

[0151] Head tube assembly 400 includes a head tube 382, which is a portion of a bicycle frame 380.

[0152] Head tube 382 is tapered, with the largest section facing down, with reference to the configuration of use (see for example FIG. 22).

[0153] Head tube 382 includes, at its opposite ends, a first bearing recess 384 and a second bearing recess 386.

[0156] Stem assembly 350 is connected to fork tube 392, and it is configured to clamp a bicycle handlebar (not shown in the drawings).

[0157] More in detail, stem assembly 350 includes a stem body 360, and screws 370 which allow tightening stem body 360 at the top of fork tube 392.

[0158] Stem body 360 includes a clamp portion 364 which, together with a faceplate (not shown in the drawings) can clamp a bicycle handlebar.

[0159] Headset assembly 490 includes a first bearing assembly 460 (in detail, a first angular contact bearing assembly 460), and a second bearing assembly 470 (in detail, a second angular contact bearing assembly 470); the first bearing assembly 460 and the second bearing assembly 470 are inserted along fork tube 392, and they are press fit, respectively, into first bearing recess 382 and second bearing recess 384.

[0160] Head tube assembly 400 could also include a bottom plug assembly 410, installed in the bottom of the fork tube 392 (see also FIGS. 3, 4).

[0161] As better explained later, bottom plug assembly 410, when installed, provides more stability to tool storage assembly 10, when inserted inside the fork tube 392 (FIG. 20), and it prevents dirt, debris, and contaminants from entering the fork tube 392.

[0162] Bottom plug assembly 410 includes a plug body 420, and an O-ring 430. Plug body 420 includes a plurality of legs 422, arranged longitudinally, and ribs 424.

[0163] Plug body 420 is made of a flexible material, such as nylon, so that legs 422 can flex open slightly.

[0164] Thanks to this feature, plug body 420 can accept insertion of tool storage assembly 10, according to the invention, in order to help prevent rattling between the tool storage assembly 10 and fork tube 392.

[0165] O-ring 430 fits around legs 422, to provide additional leg spring action.

[0166] Ribs 424 are configured to press fit plug body 420 into fork tube 392.

[0167] According to a further aspect of the invention, head tube assembly 400 includes a headset tightener 310.

[0168] Headset tightener 310 is configured to properly tighten the headset assembly 490, as will be further discussed.

[0169] By using such headset tightener 310 according to the invention, which does not decrease the internal diameter of the bicycle fork tube 392, the latter can house tools components which are slightly bigger, and this has a profound effect on usefulness of those tool components.

[0170] Importantly, headset tightener 310 does not require threading inside of fork tube 392, as is required with some of the prior art devices.

[0171] In this way, the fork tube 392 is stronger, and the installation process is much easier and less expensive, because no special thread tap is required, and the system works with any steer tube material.

[0172] Headset tightener 310, according to the invention (FIGS. 27, 28), includes an outer ring 320 and an inner ring 330, connected by a threaded coupling; inner ring 330 is configured to engage the top of fork tube 392.

[0173] More in detail, outer ring 320 includes an inner thread 328; correspondingly, inner ring 330 includes an outer thread 332, which engages the inner thread 328 of outer ring 320.

[0174] Inner ring 330 further includes an inner channel 321.

[0175] Outer ring 320 includes a split 322; split 322 is arranged radially.

[0176] Outer ring 320 further includes peripheral contours 323,324,325,326.

[0177] Particularly, contours 325,326 are divided by split 322; contours 325,326 include respective holes 327a,327b, of which first hole 327a smooth, and second hole 327b threaded.

[0178] Outer ring 320 further includes a screw 340, whose thread 342 is engaged in threaded second hole 327b.

[0179] The purpose of contours 323,324,325,326 is to provide enough grip, when turning outer ring 320 by hand, in order to provide enough preload force of headset assembly 490.

[0180] Headset tightener 310 further includes two O-rings 450; O-rings 450 fit inner channel 321, such that when outer ring 320 is pushed onto fork tube 392, there is sufficient friction to rotationally fix inner ring 330 to fork tube 392, and inner ring 330 does not rotate relative to fork tube 392 as outer ring 320 is rotated.

[0181] FIG. 25 shows headset tightener 310 prior to tightening headset assembly 490.

[0182] In actual practice, during assembly of the fork tube 392, first and second bearing assemblies 460 and 470, head tube 382, headset tightener 310 and stem assembly 350 are pushed together by hand, and stem screws 370 are tightened to fix stem body 360 to fork tube 392.

[0183] FIG. 25 shows, for the purposes of description, gap G between the top surface 329 of outer ring 320 and the bottom surface 362 of stem body 360, which, in actual practice, would be so small as to be invisible, because head tube assembly 400 would be pushed together by hand prior to tightening screws 370.

[0184] Screw 340 is loose enough, to allow rotational threaded movement between outer ring 320 and inner ring 330.

[0185] As outer ring 320 is rotated by hand, gap G will close, and then further rotation will cause first and second bearing assemblies 460 and 470 to be preloaded, removing play in the headset assembly 490.

[0186] Specifically, as outer ring 320 is rotated relative to inner ring 330, the distance between outer ring 320 top surface 329, and inner ring 330 bottom surface 334, will increase.

[0187] FIG. 26 shows headset tightener 310 after tightening headset assembly 490.

[0188] By twisting outer ring 320 while inner ring 330 remains rotationally fixed to fork tube 392, outer ring 320 top surface 329 will push against stem body 360 bottom surface 362, while inner ring 330 bottom surface 334 pushes against the top of angular contact bearing 470.

[0189] Twisting outer ring 330 causes headset assembly 490 to be become preloaded, by axially loading first and second bearing assemblies 460,470.

[0190] Proper preloading is typically verified by feeling if handlebar rotation is smooth, and by applying the front brake and pushing the bike fore and aft to feel for play.

[0191] Once proper preload is achieved, screw 340 is tightened, so to decrease the size of split 322, to bind outer ring 320 to inner ring 330: this prevents headset tightener 310 from inadvertently loosening, and from causing play in the headset assembly 490.

[0192] As previously mentioned, and according to a further aspect of the invention, tool storage assembly 10, having the features disclosed above, can be installed into head tube assembly 400 according to the invention (more particularly, housed into fork tube 392).

[0193] For easy installation and removal, O-ring 50 of container assembly 20 frictionally fits into fork tube 392.

[0194] Flange 34 of lid 30 is greater than the inside diameter of fork tube 392, to ensure that lid 30 remains above the top of fork tube 392, for safe and easy removal of tool storage assembly 10.

[0195] The outer diameter of first multi-tool assembly 130, second multi-tool assembly 60, and container assembly 20 is slightly smaller than the internal diameter of fork tube 392.

[0196] It is also emphasized that second multi-tool assembly 60, having the features disclosed above, represents an original combination of a chainbreaker and a CO.sub.2 inflator, which is accomplished in a very compact and handy way.

[0197] It has thus been seen how the invention achieves the proposed aims.

[0198] In the embodiments previously disclosed individual features, given in connection with such specific embodiments, may actually be interchanged with other different features that exist in other embodiments.

[0199] The present invention has been described according to preferred embodiments, but equivalent variants can be devised without departing from the scope of protection offered by the following claims.
