DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle pedal mounting structure.

[0002]

2. Description of the Related Art Generally, a bicycle pedal is rotatably mounted on a pair of left and right pedal arms via pedal rods so as to protrude laterally from the distal ends of the pedal arms. Here, bicycles are generally packed in a state before the parts that protrude to the side, such as the pedals, are assembled at the stage of shipment from the manufacturer, so that the packing box is made as narrow as possible. This improves the handling at the time of transportation and saves the transportation space.

[0003]

Background of the Bicycle Industry That Leads to the Invention As described above, a bicycle manufacturer is shipped without a pedal assembled, so that one set of left and right pedals is used for each pedal arm when used by a general user. It is necessary to assemble it. Heretofore, this assembling work has been performed at a stage before being sold to general users, that is, at a bicycle dealer. Usually, a dealer attaches a pedal by using a tool such as a spanner and screwing a screw portion formed at a tip of a pedal rod into a screw hole formed at a tip of a pedal arm.

Here, a pair of left and right pedals are mounted on opposite sides of the bicycle frame, and a rightward turning force is applied to the right pedal rod when the bicycle is moving forward, and the left pedal rod is applied to the left pedal rod. Usually, the right-hand pedal rod thread is a right-hand thread, and the left pedal rod thread is a left-hand thread because a leftward turning force is applied. As described above, since the screw portion of the pedal rod is oppositely screwed on the left and right, it is necessary to screw the screw portion so that the left and right directions are correct when assembling the pedal. For example, a display for distinguishing left and right is made on the end face.

[0005]

However, in recent years, with the diversification of the sales form of bicycles, the sales form in which the bicycle is directly sold to an ordinary user in an unfinished state without going through an assembling operation at a store ( (Kit sales) are showing signs of expansion in some areas, and in the case of such kit sales, the operation of assembling the pedals will be performed by general users who are final consumers. There is no problem if you are familiar with the work of assembling bicycles like a retailer, but if you are a female user who is not used to such work, there is a possibility that you will install the wrong left and right In this case, not only can the assembly not be completed after all, but if the screw is forcibly screwed in, the thread of the pedal rod or the pedal arm may be crushed. Further, forcing a person who is unfamiliar with the assembling work to use a tool such as a spanner is not preferable in terms of selling the kit.

The present invention has been made in view of such a background, and even in the case of kit sale, even a user unfamiliar with assembling work can make a right and left mistake.
It is another object of the present invention to provide a pedal mounting structure that can be mounted without using a tool such as a spanner.

[0010]

According to the first aspect of the present invention, when mounting the pedal to the tip of the pedal arm, if the mounting tool is interposed between the pedal and the pedal rod, the two are fixed for rotation. By rotating, the pedal rod can be screwed into the pedal arm. From this,
The pedal can be assembled without using a tool such as a wrench as in the related art, so that even a person who is unfamiliar with this kind of work such as a female user can easily assemble the pedal. This advantageously works in the form of kit sales.

In addition, in a state where the mounting tool is mounted and the pedal and the pedal rod are fixed in rotation, the locking claw is inserted into the insertion hole of the pedal while straddling the pedal rod. By setting the distance to be large and the distance between the insertion holes to be large in accordance with the distance, a larger torque can be transmitted between the pedal and the pedal rod, so that the pedal can be more firmly assembled.

On the pedal side, the locking claw is attached to the pedal rod.
Inserting the insertion tool into the insertion hole from the radial direction and inserting the two-face width portion into the groove on the pedal rod side completes the setting of the mounting tool. With this configuration, the mounting tool can be easily removed even after the pedal is mounted. For this reason, after the pedal is mounted, the unnecessary mounting tool can be removed from the bicycle. Moreover, the removed fixtures will be removed at a later date
Can be reused.

According to the second aspect of the present invention, the mounting tool is previously mounted between the pedal and the pedal rod at the time of shipment from the manufacturer, so that the pedal is for the right or left. Can be distinguished at a glance, and even a general user who is unfamiliar with this kind of assembling work does not have the risk of trying to assemble by mistake on the left and right, so that the thread is not crushed, it is quick and The pedal can be securely attached, and this point also works advantageously in adopting a kit sale form, and can be expanded.

[0014]

According to the first aspect of the present invention, even a general user can easily and quickly assemble the pedal without using a tool such as a spanner. New sales forms can be expanded.

Further, according to the first aspect of the present invention, the pedal can be mounted more firmly without using a tool such as a spanner, and the mounting tool can be removed after the pedal is mounted.

According to the second aspect of the present invention, the pedal can be mounted without confusing the right and left sides.

Next, an embodiment of the present invention will be described with reference to FIGS. The pedal assembling structure in this example is such that the pedal 1 is assembled to the pedal arm 4 with the assembling tool 3 interposed between the pedal 1 and the pedal rod 2 that rotatably supports the pedal. It has become.

The pedal 1 has a substantially flat plate shape having a size and strength sufficient for placing a foot, as in the prior art, and a cylindrical body 1a for accommodating the pedal rod 2 is formed at the center thereof. The pedal rod 2 is inserted into the cylindrical body 1a via a bearing (not shown), whereby the pedal 1 is rotatably supported by the pedal rod 2. The pedal rod 2 protrudes to the left in the figure, and has a two-sided width portion 2a and a right-hand thread 2b formed at the protruding portion.

On the other hand, at the end of the pedal 1 on the side where the pedal rod 2 protrudes, insertion holes 1b to 1b for inserting the locking claws 3a of the mounting tool 3 are formed. The insertion hole 1b is provided on the pedal rod 2
Are formed at two locations symmetrical with respect to the front and rear. Also,
Similarly, two insertion holes 1b, 1b are formed on the lower surface side at predetermined intervals.

Next, the assembling tool 3 includes a bifurcated locking claw 3a, which can be inserted into the insertion holes 1b, 1b of the pedal 1.
3a and a groove portion 3b having a width that allows the two-sided width portion 2a of the pedal rod 2 to be fitted with almost no gap. That is, as shown in FIG. 3, the assembling tool 3 of the present embodiment has the locking claws 3 at both ends at one edge of a strip steel plate bent in a U-shape.
A groove 3b is cut from the lower end of the other edge to form a knob edge 3d. Both locking claws 3a, 3a
Are formed at intervals corresponding to the insertion holes 1b, 1b of the pedal 1 and with a width and a plate thickness that can be inserted into the insertion holes 1b, respectively.

As shown in FIG. 1 and FIG.
A symbol for displaying left and right distinction (hereinafter referred to as
"Left and right display symbol 3e"). The illustrated mounting tool 3 is for the right pedal 1, and is indicated by "R". Therefore, a left-right display symbol of "L" is attached to the left pedal 1 mounting tool (not shown) that is paired with the right mounting tool 3.

According to the assembling structure of the present embodiment configured as described above, the pedal 1 is connected to the pedal arm 4 as follows.
Assembled in At the bicycle manufacturer's shipping stage, make sure to pack it in a compact box as small as possible.
The product is shipped without the handlebars protruding left and right, without a large basket left and right, and without a pair of left and right pedals 1,1 protruding sideways.

The pedals 1 and 1 are packed with the mounting tool 3 mounted in advance. That is, the groove 3b
The pedal 1 and the pedal rod 2 are packaged in a state where the pedal 1 and the pedal rod 2 are fixed in rotation by inserting the two flat portions 2a of the pedal rod 2 therein and inserting the both locking claws 3a, 3a into the insertion holes 1b, 1b, respectively. You. The contact edge 3c is the pedal 1
Abuts on the upper surface.

The mounting tool 3 has a left and right display symbol 3e.
Is attached to the right pedal 1 or the left pedal 1, whereby the user can easily distinguish whether the pedal 1 is for the left or the right by looking at the left and right display symbol 3e of the mounting tool 3. Shipped ready.

When a bicycle shipped from a manufacturer in such an unfinished state is sold directly to a general user, for example, in the form of a kit, the general user assembles the pedals 1, 1 by himself. It will be.
At this stage, since the mounting tool 3 is mounted on the pedal 1, it is easy to distinguish the left or right pedal 1 from the left and right display symbols 3e.

In addition, since the mounting tool 3 is mounted, the pedal 1 is fixed to the pedal rod 2 so as not to be rotatable. When assembling, the screw portion 2b of the pedal rod 2 is screwed into the screw hole 4a of the right pedal arm 4.
When the pedal 1 is rotated clockwise, the screw portion 2b of the pedal rod 2 is screwed into the screw hole 4a.

Here, the rotation of the pedal 1 and the pedal rod 2 is also fixed by inserting and removing a pin between the pedal 1 and the pedal rod 2, for example, instead of the assembling tool 3 having the exemplified configuration. It is possible to
In such a configuration, if the pedal 1 is rotated with a large force to screw the pedal 1 into the pedal arm 4, the torque is concentrated on the insertion / removal pin. May cause damage. However, according to the assembling tool 3 of the present embodiment, the both locking claws 3a, 3a formed at appropriate intervals are provided.
And the rotation between the pedal 1 and the pedal rod 2 is fixed by engaging the groove portion 3b with the width across flat portion 2b. Therefore, even if the pedal 1 is rotated with a large force, The stress applied to 1 and the like is dispersed, so that the screw portion 2a can be screwed in with a sufficient tightening torque without causing damage to each part.

After the screw portions 2a of the left and right pedals 1 and 1 have been completely screwed in, respectively, the assembly tools 3 may be removed thereafter. The assembling tool 3 pinches the knob edge 3d, and radially moves the pedal rod 2 (upward in the figure).
You can easily remove it by pulling it out. The removed attachments 3 and 3 become unnecessary when the bicycle is used, but can be used at a later time, for example, when replacing the pedal 1, so that it is preferable to keep them in a predetermined place.

When the mounting tool 3 is removed, the pedal 1 becomes rotatable with respect to the pedal rod 2, and the mounting of the pedal 1 is completed.

As described above, according to the pedal assembling structure of this embodiment, even a general user, especially a female user unfamiliar with this kind of assembling work, can use the left and right without using a tool such as a spanner. It is possible to easily assemble the pedals 1 and 1 in a predetermined state without making a mistake, so that it is possible to increase the sales of kits along with the diversification of bicycle sales forms.

It is to be noted that various modifications can be made to the exemplified configuration, and for example, although not shown, the left and right display symbols 3e of the assembling tool 3 may be displayed on the knob edge 3d. . Also, the insertion holes 1b, 1b are provided at different intervals between the left and right pedals 1, 1, and the intervals between the locking claws 3a, 3a are changed correspondingly with the left and right mounting tools 3, 3, thereby assembling. The component 3 can be dedicated to the left or right pedal 1, and according to this configuration, even a general user does not mistakenly mount the mounting component 3 on the opposite side, so that the manufacturer can ship it. It is not necessary to attach the mounting tool 3 in advance at the stage.
