SJ-~837-89 - 2 - 2664B/0089 FIELD OF THE INVENTION
The present invention relates to a fender for a bicycle where that fender is telescopic to vary lenyth of the fender.
BAOKGROUND OF THE INVENTION
Up until the last few years, substantial~y all lQ bicycles were built with fenders. However, with the recent strong trend towards racing and sports bicycles there has been an ever increasing demand to decrease weight of the bicycle and provide the bicycle with a much sportier appearance. This has resulted in the elimination of fenders 15 on most bicycles. However, by eliminating the fenders a bicycle can be very uncomfortable to ride in wet weather where the tires and in particular, the rear tire, throws water up along the back of the rider.
2û SUM~ARY OF THE PRESENT INVENTION
The present invention provides a telescopic bicycle fender designed to meet the esthetic requirements of an up to date bicycle while at the same time providing an 25 effective fender in wet riding conditions.
More particularly, the telescopic bicycle fen~er of the present invention comprises at least two interconnected fender sections which are slideably engaged with one another 30 to vary length of the fender from a minimum length equal to that of one of the fender sections to an extended length greater than that of any one of the sections.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
: 3û EMBODIMENTS OF THE PRESENT INVENTION:
Figure 1 shows a bicycle generally indicated at C
having a rear fork gcnerally indicated at F to which is fitted a telescopic fender generally indicated a 1. Fender 1 is as best seen in Figure 3 of the drawings formed by a plurality of individual fender sections comprising a center
2 ~ 8 6 or intermediate fender section 3, a top fender section 11 and a bottom fender section 19~ All of these fender sections are telescopically engaged with one another and move from a collapsed relatively short lenyth posltion shown in Figure 1 to the extended length position shown in Figure 2 of the drawings. As will be appreciated the fender sections can also be varied to many different length settings between the most compact setting of Figure 1 and the most extended setting of Figure 2.
The key to the present invention is that in its collapsed form, it assumes a minimal length equal to that of the longest fender section. In this case, all of the fender sections are of the same length and are vertically stacked 15 relative to one another when collapsed.
When collapsed the fender does little if anything in detracting from the blcycles neat and sporty appearance and only provide a very limited coverage around the tire.
20 These qualities allow the fender to be fitted on today's modern up to date bicycles.
When the fender is extended to its Figure 2 position, it provides, as shown, a substantial coverage 25 around the outer surface of the tire and therefore, is very functional in preventing water picked up from the tire from b~ing sprayed up onto the back of the rider.
The actual operation of the fender is best seen 30 having reference to Figures 2 through 5 of the drawings.
Note that Figures ~ and 5 simply show in section, the top part of each of the fender sections with the downwardly curving sides of each of the fender sections being removed for clarity purposes.
20~5~86 SJ-7837-89 ~ 5 - 2664~/~0~9 The entire fender is mounted to the bicycle fork F
by means of a mounting bolt 31 which threads up into the fork as shown in Figure 3. Mountiny bolt 31 extends through all three of the fender sections.
As best seen in Figures 4 and 5 of the drawings, the center fender section 3 does not move relative to bolt 31 while each of the fender sections 11 and 19 telescopes relative to the fixed fender section 3. Fender section 11 10 slides atop the center fender section 3 while fender section 19 slides from benea-th the fixed center fender section.
In order to accomodate the sliding action, the upper fender section 11 includes an open ended slot 15 while 15 the lower fender section 19 includes an open ended slot 25.
The upper and lower fender sections slide along their slots relative to mounting bolt 31. The slots extend a distance substantially equal to half of that of the upper and lower fender sections so that when the fender sections are 20 collapsed, they neatly fit to the Figure 1 collapsed position as determined by the inner blind ends of the slots in the upper and lower fender sections. In this collapsed position and because all of the fender sections are the same length, the entire fender collapses to a length equal to 25 that of any one of the individual fender sections.
As will be seen in Figure 2 of the drawings, the top or upper fender section 11 slides in one direction relative to the fixed fender section 3 while the lower

20~5~86 SJ-7837-89 ~ 5 - 2664~/~0~9 The entire fender is mounted to the bicycle fork F
by means of a mounting bolt 31 which threads up into the fork as shown in Figure 3. Mountiny bolt 31 extends through all three of the fender sections.
As best seen in Figures 4 and 5 of the drawings, the center fender section 3 does not move relative to bolt 31 while each of the fender sections 11 and 19 telescopes relative to the fixed fender section 3. Fender section 11 10 slides atop the center fender section 3 while fender section 19 slides from benea-th the fixed center fender section.
In order to accomodate the sliding action, the upper fender section 11 includes an open ended slot 15 while 15 the lower fender section 19 includes an open ended slot 25.
The upper and lower fender sections slide along their slots relative to mounting bolt 31. The slots extend a distance substantially equal to half of that of the upper and lower fender sections so that when the fender sections are 20 collapsed, they neatly fit to the Figure 1 collapsed position as determined by the inner blind ends of the slots in the upper and lower fender sections. In this collapsed position and because all of the fender sections are the same length, the entire fender collapses to a length equal to 25 that of any one of the individual fender sections.
As will be seen in Figure 2 of the drawings, the top or upper fender section 11 slides in one direction relative to the fixed fender section 3 while the lower
3~ fender section 19 slides in the opposite direction relative to the fixed intermediate fender section 3.
Figures 4 and 5 show that the intermediate fender section 3 includes a downwardly directed stop 7 at its one 35 end and an upwardly directed stop 9 at its other end. The upper fender section 11 includes a downwardly directed stop 201~08~
SJ-7837-89 - 6 - 2664~/~089 17 at its one end while the lower or bottorn -fender section 19 includes an upwardly directed stop 23 at its one end.
Stop 23 of the bo-ttoM fender section engages with stop 7 of the intermediate fender section while stop 17 of -the top fender sec~ion engages with stop 9 of the intermediate fender sec-tion when the fender is in its maximum extended length with the stops maintaining an interconnection between all of the fender sections. Note that the stops are locate~
in an up and down alternating pattern which does not 10 interfere with the telescopic action of the fender.
The movement of the fender sections is guided by a number of different means. Firstly, the center mounting bolt 31 which fits in the slots of the upper and lower 15 fender sections helps to guide their sliding action.
Secondl\J, channel-like guide tracks are formed between all of the fender sections. More particularly, the intermediate fender section 3 is provided with an outwardly extending rib 6 running along each side of the intermediate fender 20 section. The top fender section 11 has a double legged channel shaped lower end 13 at each of its sides with the legs on end 13 fitting to opposite sides of ribs 6 of fender section 3. Therefore, rib 6 of the intermediate fender section fits into and guides the length adjustment of the 25 top fender section-The intermediate fender section 3 further inclu~esa T-shaped lower end 21 at opposite sides of the intermediate fender section. The lower fender section 19 30includes a channel shaped lower end 21 at its opposite sides which wraps around the lower end 5 of the intermediate fender section. This interfitting of the intermediate and bottom fender sections again guides the telescopic movement of the bottom fender sectionO
The fender is provided with pressure pro~ucing 2~1~0~
SJ-7837-89 - 7 - 2664~/0089 members which maintain a tight fit between each o-~ the fPnder sections. This allows the fender seckions to be set to a desired length and to then maintain the set length.
More particularly, an upper spring member 33 is provided between the bike fork F and -the top fender section 11. A
further spring member 35 is provided between fender section 11 and fender section 3 and spring me~ber 37 is provided between the lower fender section 19 and the intermediate fender section 3. These spring members put pressure on all 10 of the fender sections to hold a set length regardless of whether that is a maximum or minimum setting or any setting in between. Furthermore, the spring members also help to prevent any rattling of the fender sections relative to one another.
Figure 6 shows a further preferred embodiment fender section l9a substantially the same as fender section 19 and having a slot 25a to allow adjustment of the fender section. Fender section 19a is additionally provided witn a 20 flexible, preferably rubber, skirt 27a which substantially closes the slot while allowing sliding movement of the fender section relative to the mounting bolt. Therefore, even when fender section l9a is in an extended position little, if any water will come up through the adjustment 25 slot past the guard skirt.
It will now be seen from the above how a telescopic fender made in accordance with the present invention can be collapsed to a short length having a neat and sporty 30 appearance to fit on a modern bicycle. At the same time, the telescopic fender can be extended to a length effective in preventing water from spraying up off of the bicycle tire when riding in we-t weather conditions.
Although various preferred embodiments of the invention have been described in detail, it will be 201~8~
SJ-7837-89 - 8 - 2664~/0089 appreciated by those skilled in the art that variations may be made without departing from -the spirit of the invention or the scope o~ the appended claims.
