Abstract

To provide a tread adjustment spacer for a bicycle pedal designed such that a sole is fitted on a tread force receiving surface without damaging a user's foot or shoe and a non-slip effect is high.SOLUTION: In a spacer detachable from a bicycle pedal body, each spacer (1a, 1b) has an elastic material (2a, 2b) for adjustment of a height from a deck surface, and is pressed down in a thickness direction according to a stepping force by exertion of the stepping force to the elastic material, so that a tip of each stud pin (3a, 3b) mounted on a pedal body 7 is further exposed from the spacer (1a, 1b). A detachable type of spacer that has sufficient thickness and elasticity and becomes deformed and thinner by pressing down a tread force receiving surface, covers and protects most of an exposed portion of each stud pin (3a, 3b) when a foot is not placed on the pedal, and exhibits a non-slip effect by projection of the stud pin when the foot is placed on the pedal.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to a tread adjustment spacer for a bicycle pedal provided with a detachable spacer for height adjustment so that the deck surface (tread surface) follows the sole of a shoe.

Background Art

[0002] Some bicycle pedals can be adjusted using a detachable spacer so that the deck surface follows the sole of a shoe. Generally, the detachable spacer is made of the same material as the pedal body, has elasticity, and does not deform. Since the driving force source of a bicycle pedal is the user's leg strength, if the tread force receiving surface of the pedal deforms, the force applied to step on the pedal will dissipate, resulting in a loss of driving force. Therefore, generally, the spacer for height adjustment from the deck surface is not made of an elastic material.

[0003] As a technique for attaching a spacer to a bicycle pedal to adjust the angle of the tread force receiving surface, a cant adjustment mechanism for a bicycle pedal is known (see Patent Document 1). This enables cant adjustment by fixing a spacer with angles provided on the upper and lower surfaces to the pedal. However, the spacer of Patent Document 1 has a problem that although angle adjustment is possible, it does not use an elastic material and no anti-slip effect can be obtained.

[0004] As a technique for attaching a spacer using an elastic material to a bicycle pedal, a bicycle pedal cover provided with an elastic material at the contact portion between the pedal and the heel of a shoe is known (see Patent Document 2). This can be used without damaging the heel even when wearing shoes with a high heel by covering the periphery of the pedal with a flexible material having elasticity. However, since the bicycle pedal cover of Patent Document 2 only covers the entire periphery of the pedal with a flexible material having elasticity, there is a problem that during use, the tread force receiving surface of the pedal deforms, the force applied to step on the pedal dissipates, and a loss of driving force occurs.

[0005] In addition, as a technique for enhancing the anti-slip effect of the deck surface, a pedal with stud pins provided on the deck surface is known. This forms stud pins by screwing bolts into female screw portions provided on the main body. In this case, spacers for height adjustment can be assembled and fixed to the pedal main body using the stud pins. As a similar technique, for example, an anti-slip device for a bicycle pedal having protrusions formed on the surface of the pedal main body is known (see, for example, Patent Document 3). In such a pedal with stud pins provided on the deck surface, the higher the protrusion height of the stud pins from the deck surface, the higher the anti-slip effect. Among those used for running on a mountain bike assuming off-road driving, there are some with a pin protrusion height exceeding 5 mm. However, while the stud pins exhibit an anti-slip effect, there are problems such as damaging the sole of the shoe or injuring the leg when stepping off the pedal.

Summary of the Invention

Problems to be Solved by the Invention

[0007] In view of such a situation, an object of the present invention is to provide an adjustment spacer for the tread surface of a bicycle pedal that allows the sole to fit on the tread force receiving surface without damaging the user's foot or shoe and has a high anti-slip effect.

Means for Solving the Problems

[0008] In order to solve the above problems, the pedal tread adjustment spacer of the present invention is a spacer that can be detached from the pedal body for a bicycle. The spacer is provided with an elastic material for adjusting the height from the deck surface. When a stepping force is applied to the elastic material, the force-receiving surface for the stepping force is pushed downward in the thickness direction according to the stepping force, and the tip of the stud pin attached to the pedal body is more exposed from the force-receiving surface for the stepping force, which is a characteristic feature. If the detachable spacer has sufficient thickness and elasticity and pushes down and deforms the force-receiving surface for the stepping force to become thinner, in a state where the foot is not placed on the pedal, the spacer covers and protects most of the exposed portion of the stud pin, and in a state where the foot is placed on the pedal, the stud pin protrudes and can exert an anti-slip effect. In this specification, the deck surface refers to the surface of the pedal body to which the spacer is not attached and that abuts the user's foot during use. Also, the force-receiving surface for the stepping force refers to the surface that abuts the user's foot when the spacer is attached to the pedal body and that moves up and down or deforms in response to the stepping force applied by the user's foot.

[0009] The elastic material in the pedal tread adjustment spacer of the present invention for a bicycle is preferably any one or a combination of silicone foam, EVA (Ethylene-Vinyl Acetate) foam, polyurethane foam, polystyrene foam, polyethylene foam, and rubber. Also, the spacer may be integrally molded with an elastic material and a rigid core material. Bubble It is also acceptable that the spacer is composed of an elastic material and a rigid member, and the elastic material may be a coil spring or a leaf spring that can move up and down. Even if the rigid member itself does not have elastic force, since it can be moved up and down in conjunction with the spring member of the coil spring or leaf spring that moves up and down, the spacer can be composed of a spring member and a rigid member and can push down the force-receiving surface for the stepping force. Here, the longitudinal direction of the coil spring overlaps with the thickness direction of the pedal body.

[0010] In the pedal tread adjustment spacer of the present invention for a bicycle, the spacer is composed of an elastic material and a rigid member, and the elastic material may be a coil spring or a leaf spring that can move up and down. Even if the rigid member itself does not have elastic force, since it can be moved up and down in conjunction with the spring member of the coil spring or leaf spring that moves up and down, the spacer can be composed of a spring member and a rigid member and can push down the force-receiving surface for the stepping force. Here, the longitudinal direction of the coil spring overlaps with the thickness direction of the pedal body.

[0011] The elastic material in the pedal tread adjustment spacer for a bicycle according to the present invention may be divided before and after the pedal body and also divided vertically above and below the pedal body, and may be divided into at least four parts. Thereby, the spacers can be divided and arranged in four regions with respect to the pedal body and its rotation axis.

[0012] The elastic material in the pedal tread adjustment spacer for a bicycle according to the present invention is a rigid spring member that has been bent and elasticized, and is provided one by one before and after the pedal body in a U-shape so as to sandwich the upper and lower parts of the pedal body, and the rigid spring member may be vertically movable. By using a rigid spring member, a spacer for anti-slip and fitting to the sole can be realized with fewer members.

[0013] The elastic material in the pedal tread adjustment spacer for a bicycle according to the present invention may be formed with a first through-hole through which a stud pin is inserted and a second through-hole through which a fastener is inserted, and may be attached to the pedal body using the fastener. The first through-hole and the second through-hole may have a plurality of holes, and the number of stud pins and fasteners may be freely designed according to the required strength.

[0014] The tread force receiving surface in the pedal tread adjustment spacer for a bicycle according to the present invention is pushed upward in the thickness direction to the original exposed position of the tip of the stud pin when the stepping force disappears from the elastic material. In this way, an elastic force acts to return to the position of the original tread force receiving surface generated in the thickness deformed by the stepping force, and it is pushed upward to the original exposed position of the tip of the stud pin. When the user places their foot and steps down, the upper surface side (tread force receiving surface) of the elastic material is pushed downward, the stud pin is exposed, and the anti-slip effect during stepping is improved. On the other hand, when the foot is removed from the pedal, the elastic force of the elastic material pushes up the tread force receiving surface, and it can be used safely without damaging the sole or the like.

Effects of the Invention

[0015] According to the pedal tread adjustment spacer of the present invention, the sole fits on the tread force receiving surface without damaging the user's foot or shoes, and when a stepping force is applied to the elastic material, the tread force receiving surface can be pushed down in the thickness direction according to the stepping force. In addition, since the tip of the stud pin attached to the pedal body is more exposed from the spacer, there is an effect of enhancing the anti-slip effect.

Modes for Carrying Out the Invention

[0017] Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. It should be noted that the scope of the present invention is not limited to the following examples and illustrated examples, and numerous changes and modifications are possible.

Example

[0018] FIG. 1 shows an external perspective view of a bicycle pedal according to Example 1. As shown in FIG. 1, the bicycle pedal 1 is composed of a pedal body 7, two spacers 1a, and two spacers 1b. That is, one spacer 1a is provided in front of the upper surface side of the pedal body 7, and one spacer 1b is provided behind it. Also, one spacer 1b is provided in front of the lower surface side of the pedal body 7, and one spacer 1a is provided behind it. Therefore, even when the pedal body 7 rotates 180°, the spacer 1a is always provided in front of the upper surface side of the pedal body 7, and the spacer 1b is provided behind it. Here, the upper surface or the lower surface is for the convenience of explanation only, and the up and down are not limited during use. The spacer 1a is composed of an elastic material 2a, stud pins (3a, 3b), and a fastener 4. The spacer 1b is also composed of an elastic material 2b, stud pins (3a, 3b), and a fastener 4. As the elastic materials (2a, 2b), materials excellent in weather resistance, wear resistance, and impact resistance are used. In this example, silicone foam is used, but for example, foamed rubber, EVA foam, etc. may also be used. The stud pin 3a is a male screw provided with a head, and the stud pin 3b is a male screw without a head. By providing the stud pins (3a, 3b), the anti-slip effect of the deck surface or the pedal force receiving surface is enhanced, and it can also be used for driving on rough roads.

[0019] FIG. 2 shows an explanatory view of the bicycle pedal according to Example 1. As shown in FIG. 2, five through holes 8a and two through holes 8b are provided in the elastic material 2a. Also, four through holes 8a and two through holes 8b are provided in the elastic material 2b. On the upper surface side of the pedal body 7, a corresponding number of female screw portions 8c are provided according to the number of the through holes (8a, 8b). When attaching the elastic material 2a to the pedal body 7, after inserting the fastener 4 through the through-hole 8b, it is screwed into the female screw portion 8c. The stud pin 3b is attached from the upper surface side of the pedal body 7. After being inserted through the through-hole 8a, it is screwed into the female screw portion 8c. Also, the stud pin 3a is attached from the lower surface side of the pedal body 7. After being screwed into the female screw portion 8c, it is inserted through the through-hole 8a. The elastic material 2b is also attached to the pedal body 7 in the same procedure as the elastic material 2a. Regarding the attachment method of the spacers (1a, 1b) provided on the lower surface side of the pedal body 7, it is the same. In this way, the spacers (1a, 1b) can be detached relatively easily with generally available tools and have a structure that is easy to replace.

[0020] Figure 3 shows an image diagram of the spacer before depression. As shown in Figure 3, in the spacers (1a, 1b), the fastener 4 is inserted through the through-holes 8b of the elastic materials (2a, 2b) and then deeply screwed into the female screw portion 8c, and is not exposed from the elastic materials (2a, 2b). On the other hand, the tip portions of the stud pins (3a, 3b) are slightly exposed from the elastic materials (2a, 2b). However, since the elastic materials (2a, 2b) have substantially the same height as the stud pins (3a, 3b), when the foot is not placed on the pedal body 7, the elastic materials (2a, 2b) cover and protect most of the exposed portions of the stud pins (3a, 3b), and it is a structure in which problems such as damaging the sole of the shoe or injuring the leg when stepping off the pedal with the foot are less likely to occur.

[0021] Figure 4 shows an explanatory diagram of the spacer of Example 1. As shown in Figure 4, when using the bicycle pedal 1, the user places the foot on the pedal body 7 with the spacers (1a, 1b) attached. As described above, since the elastic materials (2a, 2b) constituting the spacers (1a, 1b) are formed of silicone foam, they deform following the shape of the sole of the shoe 9, and a high-quality feeling of use and anti-slip performance can be obtained.

[0022] FIG. 5 is an explanatory view of the spacer of Example 1, and FIGS. (1) and (2) show image views of the spacer before and during depression, respectively. As shown in FIG. 5(1), when the user's foot is not placed on the surface of the elastic material 2, most of the exposed portion of the stud pin 3 is covered by the elastic material 2. On the other hand, when the user places their foot on the surface of the elastic material 2 or further depresses the pedal, as shown in FIG. 5(2), the sole of the shoe 9 presses down the depression receiving surface 10, and the tip of the stud pin 3 is more greatly exposed. Therefore, when the user pedals the pedal, the anti-slip effect by the stud pin 3 is naturally improved. Also, when the foot is removed from the pedal, as shown in FIG. 5(1), the exposed portion of the stud pin 3 is covered, and it can be used safely without damaging the sole or the like.

[0023] FIG. 6 shows an image view of the spacer after depression. As shown in FIG. 6, when the user's foot is placed on the bicycle pedal 1 and the pedal is depressed, as described above, the sole of the shoe 9 presses down the elastic materials (2a, 2b), and the tips of the stud pins (3a, 3b) are more greatly exposed. Also, when the foot is removed from the pedal, as shown in FIG. 3, the exposed portions of the stud pins (3a, 3b) are covered, and it can be used safely without damaging the sole or the like.

Example

[0024] FIG. 7 is an explanatory view of the spacer of Example 2, and FIGS. (1) and (2) show an image view of the core material attachment and an exploded image view, respectively. As shown in FIG. 7(1), metal core materials (5a, 5b) are embedded in the elastic materials (20a, 20b) constituting the spacer of Example 2. The elastic materials (20a, 20b) are formed of silicone foam in the same manner as the spacer of Example 1, but by embedding the metal core materials (5a, 5b), a firm assembly strength can be provided within a range that does not inhibit deformation in the thickness direction. Although not shown, recesses for embedding the core materials (5a, 5b) are provided at the bottoms of the elastic materials (20a, 20b). As shown in Fig. 7(2), the core materials (5a, 5b) are fitted into and attached to the recesses from below the elastic materials (20a, 20b). Different from such a method, for example, the elastic materials (20a, 20b) and the core materials (5a, 5b) may be integrally formed.

Embodiment

[0025] Fig. 8 shows an external perspective view of the bicycle pedal according to Embodiment 3. As shown in Fig. 8, the bicycle pedal 11 according to Embodiment 3 is composed of a pedal body 7a, two spacers 11a, and two spacers 11b. That is, one spacer 11a is provided in front of the upper surface side of the pedal body 7a, and one spacer 11b is provided behind it. Also, one spacer 11b is provided in front of the lower surface side of the pedal body 7a, and one spacer 11a is provided behind it. Therefore, even when the pedal body 7a rotates 180°, a spacer 11a is always provided in front of the upper surface side of the pedal body 7a, and a spacer 11b is provided behind it. The spacer 11a is composed of a rigid member 21a, stud pins (3a, 3b), a fastener 4, and a coil spring 6a. Also, the spacer 11b is composed of a rigid member 21b, stud pins (3a, 3b), a fastener 4, and a coil spring 6a. The rigid members (21a, 21b) are formed of hard metal, and although their own elastic force is low, the rigid members (21a, 21b) can move up and down in response to a load from above due to the provision of the coil spring 6a.

[0026] Figure 9 shows an exploded image diagram of the bicycle pedal according to Embodiment 3. As shown in Figure 9, the rigid member 21a is provided with four through holes 8a and two through holes 8b. Further, the rigid member 21b is provided with three through holes 8a and two through holes 8b. Four coil springs 6a are arranged between the rigid member 21a and the pedal body 7a. Further, three coil springs 6a are arranged between the rigid member 21b and the pedal body 7a. On the upper surface side of the pedal body 7a, a corresponding number of female screw portions 8c are provided according to the number of the through holes (8a, 8b). In addition to the female screw portion 8c, female screw portions 8d are provided one by one before and after the pedal body 7a.

[0027] When attaching the rigid member 21a to the pedal body 7a, first attach the stud pin 3a. The stud pin 3a is screwed into the female screw portion 8c from the lower surface side of the pedal body 7a, and then is inserted into the coil spring 6a and the through hole 8a in sequence. Thereafter, from the upper surface side of the pedal body 7a, the fastener 4 is inserted into the through hole 8b and then is screwed into the female screw portion 8c. The rigid member 21b is also attached to the pedal body 7a in the same procedure as the rigid member 21a. Further, the stud pin 3b is screwed and attached to the female screw portion 8d. Note that the attachment method of the spacers (11a, 11b) provided on the lower surface side of the pedal body 7a is the same.

[0028] In the bicycle pedal 11 according to Embodiment 3, when the user places the foot on it and steps on it, the rigid members (21a, 21b) are pushed downward, and the stud pin 3a is exposed. Thereby, the anti-slip effect during stepping is improved, and when the stepping force is released or the foot is removed from the pedal, the elastic force of the coil spring 6a pushes up the rigid members (21a, 21b), and it can be used safely without damaging the sole or the like. Further, regardless of the vertical movement of the rigid members (21a, 21b), the tip of the stud pin 3b is in an exposed state. This has a function of making it difficult for the user's foot to slip off the pedal to the outside.

Embodiment

[0029] Figure 10 shows an external perspective view of the bicycle pedal according to Embodiment 4. As shown in Figure 10, the bicycle pedal 12 according to Embodiment 4 is composed of a pedal body 7a, two spacers 12a, and two spacers 12b. That is, one spacer 12a is provided in front of the upper surface side of the pedal body 7a, and one spacer 12b is provided behind it. Also, one spacer 12b is provided in front of the lower surface side of the pedal body 7a, and one spacer 12a is provided behind it. Therefore, even when the pedal body 7a rotates 180°, the spacer 12a is always provided in front of the upper surface side of the pedal body 7a, and the spacer 12b is provided behind it.

[0030] The spacer 12a is composed of a rigid member 21a, stud pins (3a, 3b), a fastener 4, and a leaf spring 6b. Also, the spacer 11b is composed of a rigid member 21b, stud pins (3a, 3b), a fastener 4, and leaf springs (6b, 6c). The rigid members (21a, 21b) are formed of a rigid metal, and although their own elastic force is low, when the leaf spring 6b is provided, the rigid members (21a, 21b) can move up and down according to the load from above.

[0031] Figure 11 shows an exploded image diagram of the bicycle pedal of Example 4. As shown in Figure 11, the rigid member 21a is provided with four through holes 8a and two through holes 8b. Also, the rigid member 21b is provided with three through holes 8a and two through holes 8b. Thus, the structure of the rigid members (21a, 21b) is the same as that of Example 3. Between the rigid member 21a and the pedal body 7a, two leaf springs 6b are arranged. Also, between the rigid member 21b and the pedal body 7a, one leaf spring 6b and one leaf spring 6c are arranged. The leaf spring 6b is provided with two through holes 8e and one through hole 8f. In contrast, the leaf spring 6c is provided with one through hole 8e and one through hole 8f. On the upper surface side of the pedal body 7a, corresponding numbers of female screw portions 8c are provided according to the numbers of the through holes (8a, 8b). Also, similar to Example 3, in addition to the female screw portion 8c, on the outside of the pedal body 7a, female screw portions 8d are provided one by one in the front and back. The lower surface side of the pedal body 7a has the same structure.

[0032] When attaching the rigid member 21a to the pedal body 7a, first attach the stud pin 3a. The stud pin 3a is screwed into the female screw portion 8c from the lower surface side of the pedal body 7a and then inserted into the through hole 8e and the through hole 8a of the leaf spring 6b in order. Then, from the upper surface side of the pedal body 7a, the fastener 4 is inserted into the through hole 8b and the through hole 8f of the leaf spring 6b and then screwed into the female screw portion 8c. The rigid member 21b is also attached to the pedal body 7a in the same procedure as the rigid member 21a. Also, the stud pin 3b is screwed and attached to the female screw portion 8d. Note that the method of attaching the spacers (12a, 12b) provided on the lower surface side of the pedal body 7a is the same.

[0033] In the bicycle pedal 12 of Example 4, when the user places the foot on it and steps down, the rigid members (21a, 21b) are pushed downward, and the stud pins 3a are exposed. As a result, the anti-slip effect during stepping is improved. Also, when the stepping force is released or the foot is removed from the pedal, the elastic force of the leaf spring 6b pushes up the rigid members (21a, 21b), and it can be used safely without damaging the sole or the like. Further, regardless of the vertical movement of the rigid members (21a, 21b), the stud pins 3b are in a state where their tip portions are exposed. This has the function of making it difficult for the user's foot to slip off the pedal to the outside.

Embodiment

[0034] FIG. 12 shows an external perspective view of the bicycle pedal of Example 5. As shown in FIG. 12, the bicycle pedal 13 of Example 5 is composed of a pedal body 7b and U-shaped spacers (13a, 13b). That is, one spacer 13a is provided so as to sandwich the upper and lower parts in front of the pedal body 7b, and the other spacer 13b is provided so as to sandwich the upper and lower parts behind the pedal body 7b. The spacer 13a and the spacer 13b both have the same structure. In FIG. 12, the spacer 13b is the same as if the spacer 13a is rotated 180° in the rotation direction of the pedal and attached to the pedal body 7b. The spacer 13a is composed of a rigid spring member 22a, stud pins (3a, 3b), and a fastener 4. The spacer 13b is composed of a rigid spring member 22b, stud pins (3a, 3b), and a fastener 4. The rigid spring members (22a, 22b) are formed of a rigid metal, are formed in a U-shape so as to sandwich the upper and lower parts in front of or behind the pedal body 7b, and the upper surface side of the rigid spring members (22a, 22b) is vertically movable in response to a load from above. That is, the rigid spring members (22a, 22b) have a structure that serves as a leaf spring by themselves.

[0035] FIG. 13 shows an exploded image view of the bicycle pedal according to Example 5. As shown in FIG. 13, the rigid spring member 22a is provided with four through holes 8a on the upper surface side of the pedal 7b and three through holes 8a on the lower surface side of the pedal 7b. Further, two through holes 8b for inserting the fastener 4 are provided on the side portion of the rigid spring member 22a. The rigid spring member 22a and the rigid spring member 22b have the same structure, and the rigid spring member 22b is attached to the rear of the pedal body 7b by rotating the rigid spring member 22a 180° in the rotational direction of the pedal. Therefore, the rigid spring member 22b is provided with three through holes 8a on the upper surface side of the pedal 7b and four through holes 8a on the lower surface side of the pedal 7b. Also, two through holes 8b for inserting the fastener 4 are provided on the side portion of the rigid spring member 22b.

[0036] On the upper surface side of the pedal body 7b, a corresponding number of female screw portions 8c are provided according to the number of the through holes 8a. The same applies to the lower surface side of the pedal body 7b. On the side portion of the pedal body 7b, a corresponding number of female screw portions 8c are provided according to the number of the through holes 8b. Also, on the outer side of the upper surface of the pedal body 7b, female screw portions 8d are provided one by one in the front and rear directions. The same applies to the lower surface side of the pedal body 7b.

[0037] When attaching the rigid spring member 22a to the pedal body 7b, first, the rigid spring member 22a is fixed to the pedal body 7b using the fastener 4. Specifically, after inserting the fastener 4 into the through hole 8b provided in the rigid spring member 22a, it is screwed into the female screw portion 8c. Then, the stud pin 3a is attached. The stud pin 3a is inserted into the through hole 8a provided in the rigid spring member 22a after being screwed into the female screw portion 8c. The rigid spring member 22b is also attached to the pedal body 7b in the same procedure as the rigid spring member 22a. Also, the stud pin 3b is screwed and attached to the female screw portion 8d.

[0038] In the bicycle pedal 13 of Example 5, when the user places their foot on it and steps down, the upper surface side of the rigid spring members (22a, 22b) is pushed downward, and the tip of the stud pin 3a becomes more exposed. As a result, the anti-slip effect during stepping is improved. Also, when the stepping force is relaxed or the foot is removed from the pedal, the elastic force of the rigid spring members (22a, 22b) themselves pushes up the upper surface side of the rigid spring members (22a, 22b), and it can be used safely without damaging the sole or the like. The fastener 4 serves to fix the rigid spring members (22a, 22b) to the pedal body 7b through the through-hole 8b, and also serves as a support for the rigid spring members (22a, 22b) during use. Also, regardless of the vertical movement of the rigid spring members (22a, 22b), the tip of the stud pin 3b is in an exposed state. This has the function of making it difficult for the user's foot to slip off the pedal to the outside.
