Holder and fork frame assembly with holder

The present invention relates to a holder for inserting a motor component into a fork frame of a bicycle from one open end of the bicycle, and a fork column assembly including a holder and a fork column.

In the known holder, a frame (body) of a motor component for holding a power supply device for power supply or the like is provided on a fork frame of a bicycle (for example, Japanese Laid-Open Patent Publication No. 2005-138827). A conventional holder includes: a body inserted from an upper portion of the fork post, a lever cover contacting the lower end of the fork post, and a bolt screwed into the body through the lever cover. The holder is fixed to the yoke column by screwing the bolt into the body via the rod cover.

In the conventional holder, since there is no gap or narrow between the outer peripheral surface of the body and the inner peripheral surface of the fork post, for example, a cable connecting the switch of the handlebar to the electric transmission of the frame cannot be passed. Inside the fork frame.

The problem of the present invention is to use a holder inserted into the yoke column and allow the cable to pass through the yoke column.

The retaining member of the present invention is a retaining member for holding a motor component and inserting it from one open end to a fork frame of the bicycle. The holder has a cylindrical body. The main body has a first end, a second end opposite to the first end, and a receiving space provided between the first end and the second end for accommodating the motor component. The body has a flange portion and a gap amplifying portion. The flange portion is formed at the first end and is disposed at one of the open ends. The gap amplifying portion is formed such that a gap between an inner circumferential surface of the yoke column and an outer circumferential surface of the body is larger than other portions along the axial direction of the body.

In the holder, when the holder is mounted in the yoke column, the gap enlargement portion is formed such that the gap between the inner peripheral surface of the yoke column and the outer peripheral surface of the body is along the axial direction of the body, and the other Part is bigger. Thereby, even if the holder is inserted into the yoke column, the cable can pass through the space of the gap amplifying portion and the inner peripheral surface of the yoke column.

The motor part may include an electric storage member. Thereby, the electric storage member can be accommodated with excellent appearance.

The electric storage member may be a secondary battery. Thereby, the rechargeable secondary battery can be accommodated with excellent appearance.

The accommodating space is eccentric with respect to the outer peripheral surface of the main body toward the opposite side of the gap amplifying portion. In this case, even if a large housing space for the motor component is provided, a large gap amplifying portion can be formed.

The gap enlarged portion may be formed in a groove shape. In this case, even if the gap enlarged portion is formed, it is easy to fit the holder to the inner peripheral surface of the yoke column. borrow Thus, the holder can be guided and inserted into the yoke column.

The flange portion may have a first slit that is connected to the gap amplifying portion. Thereby, it is easy to pass the cable from the outside of the holder to the gap amplifying portion via the first slit.

The main body may have a second slit at the first end, and the two slits may be connected to the accommodating space, the gap amplifying portion, and the first slit. Thereby, even if the first end of the main body protrudes from one opening end of the yoke column, the first slit is connected to the gap amplifying portion via the second slit, and the cable is easily passed from the outside of the holder to the gap amplifying portion.

The main body may have a third slit connected to the accommodating space at the first end. Thereby, the cable can be passed from the outside of the holder to the gap amplifying portion via the third slit, the accommodating space, and the second slit.

The flange portion may have a fourth slit connected to the third slit. Thereby, the cable can be passed from the outside of the holder to the gap amplifying portion via the fourth slit, the third slit, the accommodating space, and the second slit.

The third slit is provided to face the second slit in the diameter direction of the main body, and the fourth slit may be provided in parallel with the first slit in the diameter direction of the main body. Thereby, it is easy to pass the cable from the handlebar side to the opposite side of the handlebar.

The main body may have a screw hole extending in the axial direction at the second end. The holder further includes an engaging member that engages with the other open end of the bicycle on the opposite side of the one open end, and a bolt that is screwed into the screw hole through the engaging member. In this case, the body is pulled toward the other open end side with the screwing in, and the flange portion and the engaging member have one open end and the other The open end of the square is clamped, and the body is fixed to the fork post. Thereby, the function of the holder is made part of the head part for rotatably holding the fork post to the frame.

The engaging member may have a fifth slit that is connected to a space in the fork column. Thereby, even if the engaging member is provided, the cable can be passed from the inside of the fork column to the outside through the fifth slit.

One of the open ends is provided on the rod portion of the fork column, and the other open end is provided on the fork column. In this case, the body can be simply inserted from above the yoke column.

The main body is formed to be open at the first end side, and the holder further includes a plug for closing the accommodating space and being inserted into the main body from the first end side. In this case, even if the first end side of the main body is opened in order to attach the motor component to the accommodating space, the opening can be closed by the plug.

The main body also includes a positioning portion that is engaged with the rod portion in order to position the main body with respect to the fork column in the circumferential direction. Thereby, the main body can be restricted in the circumferential direction of the rod portion. Further, the main body can be restricted in the circumferential direction of the fork post to which the rod portion is fixed.

The positioning portion may be engaged with a notch portion provided at the rod portion. Thereby, it is possible to perform positioning by using a notch portion having a function of passing a cable or the like.

The positioning portion may be provided in the flange portion. Thereby, the body can be positioned without separately arranging the positioning member on the body.

The positioning portion may be a pair of protrusions extending from either one of the first slit and the fourth slit. Thereby, the body can be positioned in a simple configuration.

The fork frame assembly of the present invention may also include a fork frame for a bicycle, and a holder for inserting the motor component into the fork column of the bicycle. A cable guiding portion for guiding the cable is formed between the inner circumferential surface of the fork post and the outer circumferential surface of the holder. In the yoke column assembly, the cable can be passed through the cable guide to the yoke column.

The yoke column assembly includes the above-described holder, and the cable guiding portion may include a gap amplifying portion. In this case, the cable guiding portion can be enlarged.

With the present invention, it is easy to pass the cable through the inside of the yoke column.
