BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of bicycle handle lags, mainly mountain bike handle lags, in which the handlebar height is increased according to the size of the rider's height and size. It is characterized in that it can be adjusted to be low or low.

[0002]

2. Description of the Related Art Recently, bicycles have been generally reduced in weight in order to reduce the cost of manufacturing and transportation, or to reduce the burden of force required during transportation and traveling. As a means for reducing the weight, generally, each part of the bicycle is simplified, and the material is made of aluminum or other light alloy, or made of plastic.

Similarly, mountain bikes are required to be lighter, but mountain bikes mainly for traveling in the fields or mountains require strength higher than that of general bicycles. However, there is a problem in achieving weight reduction.

Therefore, in order to reduce the weight of mountain bikes, the structure is simplified. As for the handle, there is a structure in which the post portion is eliminated and the handle lug for fixing the handle bar is directly tightened and fixed near the upper part of the hawk stem. By using this handle lug, unlike the conventional handle, the weight can be reduced because there is no post.

[0005]

[Problems to be Solved by the Invention] However, the handle lug that is directly fixed to the upper part of the hawk stem by tightening and fixing without the above post part can reduce the weight,
There is a problem in that the optimal riding position can be obtained only by a person of a certain height or the like.

That is, in the conventional general handle, the height of the handle bar is adjusted by adjusting the dimension of inserting the post portion into the hawk stem, whereas this handle lug has the post portion. It does not allow such height adjustment because it has no.

[0007] Also, the handle lag without this post portion, like the conventional one, also has the angle of the upper and lower angles of the neck portion projecting forward with respect to the centerline of the vertically oriented short cylindrical base portion attached to the hawk stem. Is not 90 degrees, for example 11
The angles are different, large and small, such as 0 degree and 70 degrees. Therefore, if the handlebars are attached upside down, the height of the handlebars can be changed.

However, as shown in FIG. 6, the handle lug has a thin cylinder 6 for locking the brake wire, which is provided in the neck portion 3 so as to vertically penetrate therethrough, and has a large inner diameter from the upper portion so that the outer wire 7 can be inserted. A step portion 8 having a small hole 9 through which the inner wire 10 can be inserted is formed on the lower side portion. Therefore, if the upper and lower sides of the handle bag are reversed, the outer wire 7 cannot be inserted into the thin cylinder 6 for locking the brake wire from above.

Further, as shown in FIG. 6, the handle lug has a pair of upper and lower tightening ears 11, 12 provided on both sides of a lateral tightening split groove 19 of the lug head 4, and the upper ears 11 thereof. Is formed with a round hole 22 into which the bolt head 16 can be engaged, and the lower ear portion 12 is formed with a female screw hole 23 into which a male screw portion of the tightening bolt 15 can be screwed. Therefore, when the handle lug is turned upside down, the ears 12 having the female thread 23 come to the upper side, so that the tightening bolt 15 can be inserted into the ears 11 and 12 from above and screwed. It's gone.

The present invention is intended to solve the problems of the conventional handlebar lugs for bicycles, mainly the handlebar lugs for mountain bikes. That is, the object of the present invention is to eliminate the post part for weight reduction, but to adjust the height of the handlebar according to the body shape of the rider such as height and height, the handlebar for a bicycle. To provide.

Next, the brake wire of the front brake is
The wire locking thin cylinder 6 is locked, but the wire locking thin cylinder 6 formed in the neck portion 3 of the handle lug A has the same inner diameter in both the upper half portion and the lower half portion, and is formed in the middle portion. A step portion 8 having a small hole 9 is formed. Therefore, the handle lug A
Even if the upper and lower sides are reversed, the upper part of the thin tube 6 always has an inner diameter capable of inserting the outer wire 7, and the outer wire 7 is inserted into the thin tube 6 for wire locking from above. The lower end of the outer wire 7 may be locked by the internal step portion 8 and the inner wire 10 may be pulled out downward from the small hole 9 of the step portion 8.

As described above, the handle lug A is attached to the hawk stem 1 with the upper and lower sides thereof reversed, so that the upper and lower sides of the neck portion 3 with respect to the center line a of the base portion 2 of the handle lug A. The upper and lower sides of the large and small angles α and β are interchanged. Therefore, the handlebar 5 is adjusted to the high position and the low position, and the handlebar 5 can be set according to the body shape of the rider such as the height.

[0025]

1 to 4 show an embodiment of a bicycle handle lag according to the present invention. FIG. 1 shows a case where a handle bar 5 is attached to a high position by the handle lug A. FIG. 2 shows a case where the handlebar 5 is attached at a low position.

The handle lug A has a base portion 2 in the form of a vertically oriented short cylinder for attachment to the upper portion of the hawk stem 1,
A cylindrical neck portion 3 extending forward from the base portion 2, and the neck portion 3
And a laterally short cylindrical lug head 4 for holding and fixing the handlebar 5 in front of.

The vertical short cylindrical base portion 2 has an inner diameter that can be fitted to the upper portion of the hawk stem 1, and has a vertical tightening split groove (not shown) on the rear side and a pair of left and right tightening on both sides. It has ear parts 18 in upper and lower two stages.

The neck portion 3 protruding forward is not an angle of 90 degrees in the vertical direction with respect to the center line a of the base portion 2, but a large angle α is, for example, about 110 degrees as in the conventional handle lug. , The small angle β is, for example, about 70 degrees. (In FIG. 1, the upper side has a small angle β
2 shows the case where the lower side has a large angle α, and FIG. 2 shows the case where the upper side has a small angle β and the lower side has a large angle α. )

Further, a thin cylinder 6 for locking a wire having an inner diameter into which the outer wire 7 of the front brake can be inserted is provided so as to vertically penetrate through a cylindrical part of the neck 3, and the thin cylinder 6 has A step portion 8 having a small hole 9 through which only the inner wire 10 can pass is formed in the middle portion.

Hexagonal holes 13 and 14 with which the bolt head 16 or the nut 17 can be engaged are formed in each of the ears 11 and 12, respectively.

Although the bicycle handlebar lug A according to the present invention is mainly for mountain biking,
It is also possible to use it for other types of bicycles by making the hawk stem protrude above the headset. In the figure, 21 indicates a cap.

[0032]

As is clear from the above, the handlebar lug for a bicycle according to the present invention eliminates the post portion for weight reduction, but the position of the handlebar is adjusted to the body shape such as the height of the rider. It can be adjusted higher or lower accordingly.

That is, in the past, there was a handle lug that omits the post for the purpose of reducing the weight, but this type of handle lag is different from the one with the post, and the dimension for inserting the post into the hawk stem is adjusted. I couldn't, so I couldn't adjust the height of the handlebars.

In the handlebar, even if it is attempted to attach the handlebar upside down in order to change the height of the handlebar, the small hole of the thin cylinder provided in the neck for locking the brake wire. The outer wire cannot be inserted because it comes to the upper side. As for the upper and lower tightening ears provided on the front side of the lag head, when the handle lug is turned upside down, the ears with holes that can be engaged with the bolt head go down,
Since the ear part with the female screw hole goes upward, it was impossible to fix the handlebar by passing the bolt from above.

On the other hand, in the handlebar bag for a bicycle according to the present invention, the thin cylinder for locking the wire at the neck portion is
The outer wire is insertable into the inner diameter, and a step portion with a small hole is formed in the vertical middle portion. for that reason,
Even if the handle lug is turned upside down, the outer wire can always be inserted into the wire locking thin cylinder from above and locked, and the inner wire can be pulled out downward from the small hole.

Further, the pair of upper and lower ears of the lag head are formed with hexagonal holes on either side of which the bolt head or the nut can be engaged. Therefore, even if the handle lug is turned upside down, the upper ear can always engage the bolt head, the lower ear can engage the nut, and the tightening bolt can be engaged from above. The handlebar can be fixed by inserting it and screwing a nut to the bottom to tighten it.

Therefore, the bicycle handle bag according to the present invention can be attached with no trouble to the brake wire or the handle bar even if the upper and lower sides are reversed and tightened and fixed to the upper part of the hawk stem. The height of the handlebar can be adjusted to be higher or lower depending on the body shape such as the height of the rider, although the post is omitted for the sake of realization.
