Abstract

The invention relates to the construction of rear-view mirrors mounted on a steering wheel of a two-wheeled vehicle and can be used in bicycle building and motorcycle construction. The purpose of the invention is to improve manufacturability while simultaneously expanding the range of adjustment of the mirror in height. The holder of the rear-view mirror contains the plug 1 of the pipe of the roll, made in the form of three parts that are detachably interconnected. One detail of the plug 1 is made in the form of a hollow sleeve 3 with a longitudinal through section. At one end of the sleeve 3, there are two identical length of the end protrusions and one additional restrictive protrusion 6, which is elongated compared to the said protrusions. Two other parts of the composite plug 1 are made in the form of clamping washers 7 and 8, which are similar in shape and are mirrored. Both washers have annular facing towards each other edge bends 9 with radius grooves 11 to cover the rack 12 of the holder. 1 hp f-ly, 6 ill.

The invention relates to the construction of rear fork mirrors mounted on the steering wheel of a two-wheeled trans-Aortic vehicle and can be used in bicycle building and motorcycle construction.

The purpose of the invention is to improve manufacturability while simultaneously expanding the range of adjustment of the mirror in height.

FIG. 1 shows the rear view mirror holder assembly, a side view of FIG. 2 shows section A-A in FIG. one; on league. 3 - bushing, axonometric projection; in fig. 4 - one of the clamping washers; in fig. 5 - the same, view | from the side; in fig. 6 - second clamping washer.

The holder of the rear-view mirror of a two-wheeled vehicle contains a plug 1 of a pipe 2 rolls. Plug 1 is made integral in the form of three parts that can be detachably interconnected. One part of the plug 1 is made in the form of a hollow sleeve 3 with a longitudinal through section 4. At one of the ends of the sleeve 3 two identical lengths of the protrusions 5 and one additional, one-sided extension 6, as compared with the projections 5, are made. Two other parts of the plug 1 made in the form of similar in shape, mounted in a mirror image of the clamping washers 7 and 8.

In addition, the washers 7 and 8 are annular facing towards each other edge bends 9, respectively. The radial grooves 11, designed for contacting (by means of coverage) with the stand of the 12 mirror holders installed between them, are made symmetrically with respect to the ‑ edges of which are symmetric about the horizontal plane passing through the center of the axial hole 10 of the parts of the plug 1. At the same time, the clamping washer 8 is outer of the parts of the plug 1, is made only with an axial bore 1C /, and the clamping washer 7, in addition to the hole 10, has holes 13 for the end protrusions 5 of the sleeve 3 and hole 14 for the end protrusion 6 of the sleeve 3. The stub element is made bolt 15, interacting with the nut 16, and installed in the axial hole 10 of the parts of the composite plug 1. The nut 16 has the shape of an expansion cone and you 5

made with an external fixing protrusion (not shown), which eliminates slippage when tightening the tensioning element due to the interaction of the said protrusion with a longitudinal section 4 of the sleeve 3. It is advisable to perform a groove or notch on the lower part of the stand 12 of the holder.

The mounting of the rear view mirror holder is carried out as follows.

First, a composite cap 1 with a clamping element is assembled from the parts. For this, a nut 16 is inserted from the flat die of the split sleeve 3, placing its lug in the section 4 of the sleeve 3. Then the end protrusions 5 and 6 of the sleeve 3 are inserted into the holes 13 and 14 of the clamping washer 7. Another clamping washer 8 through the axial hole 10 is worn on the bolt 15, the free end of which is inserted through the remaining parts of the plug 1 and inserted into the axial hole of the nut 16. In this case, the clamping washers 7 and 8 are arranged in a mirror image relative to each other, i.e. their annular bends 9 with radius notches 11 are directed towards each other.

The lower part of the post 12 is inserted into the holes of the clamping washers 7 and 8 formed by the radial grooves 11, and the holder pre-assembled in this way is placed in the pipe 2 of the roll, while the sleeve 3 of the plug 1 is installed completely inside the pipe 2, and the clamping washers 7 and 8 outer end of the last. Then, the post 12 is set to the required height, and, tightening the bolt 15, which interacts with the spacer nut 16, the pole 12 and the stopper 1 are securely fixed at the same time in the pipe 2 of the roll. This is ensured by the fact that the bolt 15 tightens the clamping washers 7 and 8 while tightening, reducing the distance between the radius grooves 11 covering the rack 12. The reliability of the contact increases significantly due to the stop formed by the protrusion 6 of the sleeve 3. Preventing excessive tightening the bolt 15, resulting in other structures for rapid wear and breakage of the thread, in the proposed design, the protrusion 6 is also the main and guiding element regulating the optimal spatial interposition of detachable parts Avna plugs 1 and ISZ ™ L & & $$ 58 &

Claims (2)

Claim 1. The holder of the rear-view mirror of a two-wheeled vehicle, including a strut and a composite, 35 made of detachably interconnected parts, a plug for the steering wheel pipe with a coupling element with a nut installed in the longitudinal axial hole, made in the form of a fixing spacer cone, one of the 'plug parts made in the form of a hollow with a longitudinal through section of a sleeve with end protrusions for interacting with the corresponding holes made in another part of the plug, characterized in that, in order to To improve manufacturability while expanding the range of mirror adjustment by height, the other part of the plug is made in the form of a clamping washer with an annular edge bend having radius recesses for contact with: the holder stand, and a similar additional clamping mirror is installed from the outer end of the plug in relation to the said washer washer. 2. The holder according to claim 1, which requires that, in order to increase the durability of the parts fixing the rack, a restrictive end protrusion is made on said sleeve, and a hole is made in the main washer through which the protrusion passes for stop into the inner surface of the additional washer, the length of the limiting protrusion being greater than the end protrusions.
