Definitions
- the present invention relates to a bicycle stem, and more particularly to a bicycle stem that can be easily removed or coupled to the handle by the operation of the lever.
- a general bicycle 100 has a rear wheel connected to a frame 110 at a rear side thereof, and a fork 120 at a front side thereof.
- the stem 140 includes a body portion 141 and a handle fixing portion 142.
- the fork 120 penetrates and is fixed by a bolt.
- a handle seating groove in which the handle 130 is seated is formed at the other side of the body 141, and a handle fixing part 142 is provided to surround and fix the handle. Therefore, the handle 130 is positioned to surround the handle fixing portion 142 in a state seated in the handle seating groove of the body portion 141, the handle fixing portion 142 and the body portion 141 using the bolt 143. By fixing), the handle 130 can be fixed.
- the present invention has been made to solve the above problems, and an object of the present invention is to provide a bicycle stem that can be easily separated or coupled to the handle by the operation of the lever.
- the body portion is formed with a handle seating groove is seated on one side;
- a handle fixing part whose one end is rotatably connected to one side of the body portion;
- fastening means for fixing the other end of the handle fixing part to the body part.
- the fastening means it is preferable to include a link passing through the other end of the handle fixing portion, a lever that one end of the link is axially coupled, and a link fixing portion for fixing the other end of the link to one side of the body portion. .
- one end of the link is eccentrically coupled to the lever so that the distance between the axis of the link and the link fixing portion is variable.
- the outer circumferential surface of the handle fixing portion is preferably formed with a groove in which the lever is seated.
- the link fixing portion is provided on one side of the body portion, it is preferable that the slit is formed so that the link passes while rotating.
- the other end of the link is preferably provided with a head having an outer diameter larger than the slit.
- the end of the link fixing portion is further provided with a locking step for preventing the head from being randomly separated.
- 1 shows a general bicycle.
- FIG. 2 shows the stem of the bicycle shown in FIG. 1.
- FIG. 7 shows the operating state of the embodiment shown in FIG.
- the handle 130 is fixed to one side, the fork 120 is penetrated to the other side.
- a hole 121 is formed in an upper portion of the fork 120 and is fixed by using a washer W and a bolt B in a state of penetrating the stem 1.
- the embodiment 1 includes a body portion 10, a handle fixing portion 20, and a fastening means 30.
- the body portion 10 has a handle seating groove 11 is formed on one side of the handle is seated, the fork through hole 12 through which the fork penetrates is formed. Alternatively, it may be formed integrally with the fork.
- the handle fixing portion 20 is provided at one side front of the body portion 10, in particular one end is rotatably hinged (H) to one side of the body portion (10).
- the handle fixing portion 20 is formed in the handle seating groove 21 is seated on the handle is consequently configured to surround the handle with the body portion 10.
- the fastening means 30 is a component for fixing the other end of the handle fixing part 20 to one side of the body portion 10.
- the fastening means 30 includes a link 31, a lever 34, and a link fixing part 35.
- the link fixing part 35 is formed to protrude upwardly on one side of the body portion 10, and a slit 35a through which the link 31 rotates is formed.
- a locking step 35b is formed at the rear side.
- the link 31 is provided through the other end of the handle fixing portion 20. 5 and 6, one end of the link 31 is axially coupled to the lever 34, and in particular, is eccentrically coupled to the lever 34. This is to allow the distance between the shaft center 33 of the link 31 and the link fixing portion 35 to be varied.
- the other end of the link 31 is provided with a head 32 for fixing to the link fixing portion (see '35' of Figure 4).
- the head 32 has a larger outer diameter than the slit (see '35a' in FIG. 4).
- the lever 34 is a component for varying the axis of the eccentrically coupled link 31. That is, by rotating the lever 34, the shaft center 33 of the link is displaced. In addition, a groove in which the lever 34 is seated is formed on the outer circumferential surface of the handle fixing part 20. Therefore, the lever 34 is to be seated without protruding to the outer circumferential surface of the handle fixing portion 20 (see FIG. 4).
- FIG. 7 describes the process of separating the handle in the stem according to the present invention.
- the handle 130 is seated on one side of the body portion 10, the handle in front of the handle 130
- the fixing part 20 is wrapped, and the link 31 penetrating the other side of the handle fixing part 20 is in a state in which the head 32 is caught in the slit of the link fixing part 35.
- the head 32 has a diameter larger than that of the slit, and the locking jaw 35b is formed at the end of the link fixing part, so that the handle 130 is stably fixed.
- the link 31 can be rotated and separated from the link fixing portion 35 without interference of the head 32 (see FIG. 7C).
- the stem according to the present invention can remove the handle by a simple operation of rotating the lever without a driver or a separate tool. You can also reverse the above steps and secure the handle back to the stem.
- FIG. 8 shows another embodiment of the stem according to the invention
- FIG. 9 shows the main parts of the embodiment shown in FIG. 8.
- another embodiment according to the present invention includes a jig 36 for connecting a pair of links 31 and a spring 38 provided at an outer circumference of the link 31. It includes more.
- the jig 36 is a component that connects the pair of links 31 to rotate at the same time.
- a pair of links 31 are configured separately so that each link 31 is rotated separately when the link 31 is fixed or detached from the link fixing part 35.
- the pair of links 31 can be rotated at the same time using the jig 36.
- the spring 38 is a component that applies an elastic force so as to protrude the link 31 from the handle fixing portion 20 as much as possible.
- a washer is further provided between the spring 38 and the handle fixing part 20.
- the handle of the bicycle can be easily detached from or coupled to the frame by operating the lever, it is very easy to store the bicycle in a car trunk or the like.
