The knuckle guard covers the lever holder and the hand lever together with the hand from the front side in the traveling direction.

The operation cable whose one end is connected to the hand lever comprises an outer tube and an inner cable inserted inside the outer tube. The inner cable is inserted into a through hole formed in the lever holder and the hand is projected at the protruding end. It is connected to the lever.

On the other hand, the end of the outer tube is connected to the adjusting member at the side of the lever holder near the through hole, and the periphery of this connecting portion is a cover (hereinafter
It is covered with waterproof boots).

In place of the through hole for inserting the inner cable, the lever holder is provided with a cable set groove opened forward in the traveling direction, and the inner cable is inserted into the cable set groove from the front side. Things are also known.

[0007]

By the way, when water adheres to the exposed end of the inner cable near the hand lever when traveling in the rain or the like, the water penetrates the inner cable by capillary action and enters the outer tube. I will end up.

In particular, since a general inner cable is formed by twisting a plurality of single wires made of thin steel wire into a wire shape, water is more likely to enter due to the capillary phenomenon.

When water enters the outer tube, rust of the inner cable adheres inside the outer tube, which may reduce the durability. Therefore, it is desired to improve the waterproof performance at the end of the operation cable near the hand lever.

The exposed end of the inner cable, which requires such waterproofing, has a connecting portion between the lever holder and the outer tube, a gap between the lever holder and the hand lever, and the cable setting groove when the cable setting groove is provided. It is the inner part.

Of these, the connecting portion between the lever holder and the outer tube can be waterproofed by the waterproof boot as in the conventional example.

Further, in both the inside portion of the cable set groove and the gap portion between the lever holder and the hand lever, water that comes in from the front in the traveling direction when traveling in the rain or water that has dropped from the upper surface of the lever holder enters. Will be done.

In addition, the gap between the lever holder and the hand lever expands when the hand lever is rotated to the full stroke state (during operation), and the base end portion of the hand lever moves to the side of the lever holder. Since the lever holder is displaced and is not covered with the lever holder, the possibility of the water entering the gap is further increased.

The waterproof treatment for the inside portion of the cable set groove and the gap portion between the lever holder and the hand lever is solved by covering the entire front side in the traveling direction of the lever holder and the hand lever with a knuckle guard as in the conventional example. To be done.

However, for this purpose, it is necessary to attach a knuckle guard, which is large enough to cover the hand and is a special member, and moreover, there are very few models which can be equipped with the knuckle guard. ing.

Therefore, according to the present invention, a hand lever having a high waterproof performance can be constructed by using existing hand lever device constituent parts as much as possible without using a large and special member such as a knuckle guard. The purpose is to provide a device.

According to the present invention, since the covering means covers the entire opening on the front side in the traveling direction of the cable setting groove provided in the lever holder, water flying from the front side in the traveling direction and the lever holder even when traveling in rain. Water dripping along the upper surface of the cable does not enter the cable set groove, and as a result, the waterproof performance of the operation cable can be improved.

Moreover, since the covering means is simply attached along the cable set groove, the covering means can have a small size and a simple structure, and this attachment is also easy because it has elasticity or flexibility.
In addition, when a waterproof means for waterproofing the connecting portion between the one end of the outer tube and the lever holder is provided, it can be formed extremely easily by using an existing member by integrally forming it with the existing waterproof means. it can.

Therefore, without using a large and special member such as a knuckle guard, the existing hand lever device constituent parts can be used as much as possible and a part thereof can be deformed to make the structure small and simple, and yet waterproof. A hand lever device with high performance can be obtained.

Further, if a front shield portion is provided in a part of the covering means to cover the gap formed between the lever holder and the lever holder from the front in the traveling direction when the hand lever is operated, this gap is created when the hand lever is operated. However, since the front shielding portion shields the front of the gap in the traveling direction, it is possible to shield the water coming from the front to the gap between the hand lever and the lever holder, and it is easy to prevent the water from entering through the gap. .

Further, if the lever holder covers the base end portion of the hand lever from the non-actuated position to the full stroke position, it is formed between the hand lever and the lever holder in plan view when the hand lever is actuated. Since the gap is always covered from above, it is possible to prevent the situation where the water that has traveled along the upper surface of the lever holder drops into the vicinity of the exposed end of the inner cable located in the gap and enters the operation cable.

Furthermore, in the case of a type in which a hand lever is used as a hand brake, the cable setting groove and the covering means are provided, and a parking lever for holding the hand lever in an operating position during parking is provided, the parking lever is provided. Is provided so as to be continuous with the covering means when seen from the front in the traveling direction of the vehicle body when the vehicle is traveling, the gap formed between the lever holder and the hand lever is shielded in the forward direction in the traveling direction, so that the hand lever and the lever are closed. It can be used as a shielding means against water coming from the front between the gaps between the holders, and prevents water from entering the gaps and the cable set groove in cooperation with the covering means, improving the waterproof performance at the end of the operation cable. While you can

The waterproof member 5 is wholly formed of a material having elasticity or flexibility and waterproof property such as rubber or elastomer, and a stopper portion 50 that tightly covers the outer tube 44 and a part thereof. And a set groove covering portion 51 which extends in the direction of the cable set groove 12 and extends on the front end face 10b of the lever holder 1 along the cable set groove 12.

Stopper portion 50 and set groove covering portion 51
Are parts of specific examples of the waterproofing means and the covering means in the present invention, and the structure of only the stopper part 50 without the set groove covering part 51 functions similarly to the waterproof boot.

The stopper portion 50 is the outer tube 44.
The end of the outer tube 44 is immovably integrated with the stopper 50 around the end of the stopper tube 50.

The contact surface 52 of the stopper portion 50 with respect to the lever holder 1 is adapted to be in close contact with the periphery of the through hole 11 and the opening of the cable setting groove 12 in the end surface 10a on the side opposite to the lever so as to cover it liquid-tightly.

As is apparent from FIGS. 7 to 9, the set groove covering portion 51 has a substantially T-shaped cross section slightly longer than the length of the cable set groove 12, and has an umbrella portion 53 and a fitting portion 54. The set groove covering portion 51 is continuous with the shielding portion 20 of the parking lever 3 when viewed from the front in the traveling direction when the vehicle is traveling.

The umbrella portion 53 is wider than the width of the cable setting groove 12 and is located on the front end face 10b.
The portion near the opening is liquid-tightly coated from the front in the traveling direction.

The fitting portion 54 has a structure in which it is tightly fitted by elastically deforming and pushing it into the cable set groove 12, and a pair of projections 55 projecting to both sides are formed at the distal end in the length direction thereof. Has been done.

When the fitting portion 54 is fitted into the cable setting groove 12, the projection 55 is recessed into the recess 12a (FIG. 8) formed on the inner wall surface of the tip end side of the cable setting groove 12 near the lever side end surface 10c. It is designed to engage.

By engaging the projection 55 with the recess 12a, the entire length of the cable setting groove 12 is always reliably covered with the set groove covering portion 51.

If the protrusion 55 does not exist, the set groove covering portion 51 is deformed in the lengthwise direction and contracts to cover the end portion of the cable set groove 12 near the lever side end surface 10c with the set groove covering portion 51. There is a possibility that some parts will not be seen.

As is apparent from FIG. 2, when the hand lever 2 is not operated, the front end portion 13b of the overhanging portion 13a forms the shoulder portion 33 of the hand lever 2 and the initial gap g between the shoulder portion 33 and the lever holder 1. It covers from above.

As is apparent from FIGS. 4 and 5, when the hand lever 2 is operated, the shoulder portion 33 and the lever-side end surface 10 are
A relatively large gap G during operation is formed between c and c when viewed from the front in the traveling direction.

Of the gap G at the time of operation, the portion through which the exposed end 48 of the inner cable passes is always the protruding portion 13a.
The upper side is covered with a laterally extending end portion 13c.

That is, as is apparent from FIGS. 2 and 4, the laterally extending end portion 13c of the overhanging portion 13a is located in the non-operating position in the vicinity of the lever holder side end surface 37 of the base end portion 31 (see FIG. The coating is performed from above from 2) to the operating position (Fig. 4) in the full stroke state.

However, the laterally extending end portion 1 of the overhanging portion 13a
The portion covered by 3c in the full stroke state of the hand lever 2 is located on the spindle hole 32 side from the point P (FIG. 7) where the lever holder side end surface 37 of the base end portion 31 and the exposed end portion 48 of the inner cable intersect. The part is enough.

Further, as can be seen most clearly in FIG. 7, the shoulder portion 33 including the initial gap g, the gap G during operation, and the openings of the cable mounting groove 35 and the slit 36.
The front side of each of the traveling positions in the traveling direction is shielded by the shielding portion 20 of the parking lever 3 in the non-operating state.

Next, the operation of this embodiment will be described. First,
To attach the waterproof member 5 to the lever holder 1, in FIG. 7, the exposed end 48 of the inner cable 45 is extended from the fitting portion 46 of the outer tube 44 integrated with the stopper portion 50.

Then, the exposed end portion 48 is inserted into the through hole 11 from the opening portion of the cable set groove 12 and the locking tool 4 is inserted.
9 is locked in the cable mounting groove 35 of the hand lever 2.

After that, the fitting portion 46 is fitted into the through hole 11, and the contact surface 52 of the stopper portion 50 is fixed to the end surface 1 on the side opposite to the lever side.
0a and the fitting portion 54 of the set groove covering portion 51
Is elastically deformed and pushed into the cable setting groove 12, the umbrella portion 53 is brought into close contact with the front end face 10b, and the projection 55 is locked in the recess 12a.

As a result, the entire opening of the through hole 11 and the cable setting groove 12 in the opposite end face 10a and the front end face 10b of the lever holder 1 is liquid-tightly closed, and when the hand lever 2 is rotated, the inner cable 45 is rotated. Reciprocates in the through hole 11 in the pulling direction or the returning direction.

When running in the rain in this state, first, as shown in FIG.
Also, when the hand lever 2 shown in FIG. 3 is not operated, the water coming from the front in the traveling direction cannot enter the cable setting groove 12 by the setting groove covering portion 51, and the stopper portion 50 causes the water from the side opposite to the lever side end surface 10a. Intrusion is also blocked.

The lever-side end surface 10 of the lever holder 1
The initial gap g between the c and the shoulder portion 33 of the hand lever 2 is shielded by the shielding portion 20 of the parking lever 3 in the front in the traveling direction, so that water flying from the front in the traveling direction is less likely to enter this portion as well.

Further, with respect to the water that has dropped along the surface of the upper surface portion 13, the end face 10a on the side opposite to the lever 10 and the end face 10 on the front side are formed.
At point b, the invasion can be prevented by flowing and dropping around the stopper portion 50 and the surface of the umbrella portion 53 of the set groove covering portion 51.

On the side of the initial gap g, the front end portion 13b of the overhanging portion 13a covers the shoulder portion 33, so that it can be dropped from the surface of the upper surface portion 13 without entering the initial gap g.

Next, the hand lever 2 shown in FIG. 4 and FIG.
When the hand lever 2 is actuated, the hand lever 2 rotates counterclockwise against the return spring 41, and a gap G between the shoulder portion 33 and the lever-side end face 10c during operation is largely opened forward. It is formed.

However, the gap G at the time of this operation and the front side of each of the shoulder portions 33 including the openings of the cable mounting groove 35 and the slit 36 in the traveling direction are the shielding portions 20 of the parking lever 3.
Is shielded by.

Therefore, also in this case, as in the non-operating state, the water that comes in from the front in the traveling direction when traveling in the rain has the gap G.
It becomes difficult to enter.

For this reason, when the vehicle is running, the shield 20 of the parking lever 3 and the waterproof member 5 are viewed from the front in the traveling direction.
Since the set groove covering portion 51 of No. 1 is continuous, the initial gap g is obtained by the cooperation of the shielding portion 20 and the set groove covering portion 51.
It is possible to effectively prevent water from entering the gap G and the cable set groove 12, and improve the waterproof performance at the end portion of the operation cable 4.

When the parking lever 3 is actuated to rotate in the counterclockwise direction, the gap G is opened to the front in the traveling direction, but since the vehicle is parked, water from the front in the traveling direction with respect to the gap G is released. The invasion of is almost no problem.

Further, the base end portion 31 of the hand lever 2 is
It is covered with the overhanging portion 13a during the operation and the non-operating time, and in particular, the upper portion of the gap G where the exposed end portion 48 is located is always covered with the overhanging portion 13a.

For this reason, the water that propagates on the surface of the upper surface portion 13 in the direction of the gap G is laterally extended end portion 13 of the overhang portion 13a.
Since the liquid is dripped as it is from the tip of c to the place away from the exposed end 48, it is possible to reduce the intrusion into the gap G and prevent the adhesion to the exposed end 48.

In addition, the waterproof structure on the end face 10a on the side opposite to the lever and the end face 10b on the front side maintains the same waterproof performance as when not in operation.

Therefore, in running in the rain, water can be prevented from adhering to the exposed end portion 48 of the inner cable 45 or significantly reduced regardless of whether the hand lever 2 is operated or not, and therefore the operation cable 4 in the running in the rain can be prevented. The waterproof performance can be significantly improved.

Moreover, it is not necessary to provide a large and special member such as a conventional knuckle guard, a lever device having a small size, easy to manufacture, and a high waterproof performance can be obtained, and various specifications having different specifications can be obtained. Since it can be applied to models as well, the degree of freedom in application is increased.

Further, the set groove covering portion 51 waterproofs the front opening of the cable setting groove 12 in the traveling direction, shields the clearance G on the front side in the traveling direction with respect to the gap G when the parking lever 3 operates the hand lever, and the base end of the protruding portion 13a. The coating of the portion 31 can be carried out individually, and the waterproof performance can be improved for each. Naturally, if all of these are provided, the waterproof performance can be maximized.

Further, since the set groove covering portion 51 is integrally formed with the stopper portion 50 which functions similarly to the conventional waterproof boot, the set groove covering portion 51 can be easily formed and the existing waterproof boot is slightly changed. You can use just by adding.

Moreover, the fitting groove 54 is fitted to the set groove covering portion 51.
By providing this, the cable set groove 12 can be waterproofed and the set groove covering portion 51 itself can be attached by pushing this into the cable set groove 12.

Furthermore, the base end portion 31 of the hand lever 2
The overhanging portion 13a that covers is only required to be slightly changed in a part of the lever holder 1, so that the existing parts can be used in this case as well.

Moreover, since the parking lever 3 is also an existing part, it can be effectively used as a waterproof member.

FIG. 10 shows a modified example applied to a hand brake for a motorcycle that does not have the parking lever 3 and corresponds to FIG. FIG. 11 is a diagram corresponding to FIG. 3 in this example.

As is clear from these figures, the waterproof member 5
The set groove covering portion 51 is integrally formed with a front shield portion 56 that abuts on the front end surface 38 of the base end portion 31 and extends so as to cover this portion.

The length of the front shield 56 is the same as that of the hand lever 2
Gap G and shoulder 3 formed during the operation of
3, it is sufficient to shield the front side in the traveling direction of the portion including the cable mounting groove 35 of the front end face 38 and the opening of the slit 36.

Therefore, even if the parking lever 3 is not provided, water is blocked from the front in the traveling direction regardless of whether the parking lever 3 is in operation or not. Moreover, even if this structure is adopted, the number of parts does not increase, and the manufacturing is easy.

At this time, the front shield 56 is attached to the front end face 38.
If it is formed so as to be elastically deformed to the side at all times, when the hand lever 2 is rotated, the front shield part 56 can be freely deformed so as to approach the front end face 38 by self elasticity, so that the shielding effect is further enhanced.

The front shield portion 56 is preferably wider than the set groove covering portion 51 in order to further enhance the shield effect. However, it is also possible to have the same width and shape as the extension of the set groove covering portion 51, and it is advantageous in manufacturing to form the set groove covering portion 51 integrally with the set groove covering portion 51. It is also possible to form the above and to attach it to the set groove covering portion 51 later and integrate it.

This modification has the same structure as that described in FIGS. 1 to 9 except that the parking lever 3 is not provided and the front shield portion 56 is provided on the waterproof member 5. The same reference numerals are given to the parts and detailed description will be omitted.

The present invention is not limited to the above embodiment and can be variously modified. For example, the vehicle to be mounted may be not only a motorcycle but also a vehicle such as a buggy car or an agricultural car that uses a hand lever device that requires waterproofing when traveling in the rain.

The hand lever device is not limited to the brake lever except when a parking lever is used, and various kinds of clutch levers for motorcycles and throttle levers and clutch levers for general-purpose models can be applied.

Further, the waterproofing means can have various structures such as a simple tubular waterproofing boot as in the above-mentioned conventional example, or one that is fitted and attached to the lever holder integrated with the outer tube as in the above embodiment. .

Further, the covering means is sufficient if it can cover the opening of the cable set groove, and it is not always necessary to fit and mount it in the cable set groove, and various structures are possible. For example, the covering means may be formed of a flexible material, and the attachment portion may be formed into a leaf spring shape and pushed into the cable set groove to be fixed.
