Description

  The present invention relates to a pedal device in which a pedal tread surface of a pedal mounted on a vehicle is covered with a pad formed of a metal plate and an elastic member.

  3A and 3B are diagrams showing a normal pedal device used in a conventional general vehicle, in which FIG. 3A is a front view and FIG. 3B is a cross-sectional view taken along the line CC in FIG. 4A and 4B are views showing a conventional pedal device provided with a pad made of an aluminum plate and a rubber material, wherein FIG. 4A is a front view and FIG. 4B is a cross-sectional view taken along the line DD in FIG. .

  As shown in FIGS. 3A and 3B, a normal pedal device 100 used in a conventional general vehicle has a rubber pad 300 on an outer peripheral portion 220 of a pedal tread surface 210 of a pedal 200. The bank portion 320 formed on the back outer peripheral portion 310 is attached by being manually covered. Such a pedal device 100 has a problem that it lacks design because the pedal tread 210 is simply covered with the pad 300.

  As the pedal device 400 with improved design, for example, there is a so-called sports pedal using a so-called sports pad as shown in FIGS. 4 (a) and 4 (b). In this pedal device 400, a rubber material 700 for preventing slipping is engaged with a plurality of holes 610 formed in the aluminum plate 600 from the back surface side, and the aluminum plate 600 and the pedal tread surface 510 of the pedal 500 are connected. In this state, the rivet 800 is fixed. In the case of this pedal apparatus 400, the design is improved by using a glossy aluminum plate 600.

  In addition, there is known a pedal device that prevents the shoe sole from slipping by extending a rubber material disposed on the surface side of the aluminum plate to the side of the plate and improving the appearance (for example, Patent Document 1).

JP 2006-236179 A (FIGS. 1 to 5)

  However, like the pedal device disclosed in Patent Document 1, when a plate (aluminum substrate) is insert-molded into a rubber material, the plate is provided on the entire surface of the rubber material other than the substantially cylindrical portion and the streak-like portion. This makes it difficult for the pad to bend and bend, so that the pad cannot be attached to and detached from the pedal tread by hand assembly. As a result, when the rubber material is worn and the pad is replaced, a special jig is required.

  In the case of the pedal device 400 as shown in FIGS. 4A and 4B, a rubber material 700 is placed on the pedal tread surface 510, and a plate 600 is placed on the rubber material 700, and a plurality of such devices are placed. It must be fixed with a fixing member such as rivet 800. For this reason, there existed a problem that workability | operativity was bad and the number of parts and assembly man-hours were many, and it became a cost increase.

  Therefore, the present invention has been made in view of the above circumstances, and an object thereof is to provide a pedal device that does not require a fixing member such as a rivet and has excellent assemblability.

  In order to solve the above-described problem, the pedal device according to claim 1 is a pedal device including a pad that is formed of a metal plate and an elastic member and covers the pedal tread surface of the pedal. At least a part of the pad attachment portion to be attached is formed of only the elastic member.

According to the first aspect of the present invention, when the pedal device is mounted so that at least a part of the pad mounting portion with respect to the pedal tread is formed of only the elastic member, the pedal tread is covered with the elastic member. In addition, it is possible to elastically deform a portion formed by only the elastic member. For this reason, a pad can be easily assembled | attached to a pedal tread surface, making it elastically deform so that the site | part formed only with the elastic member might warp. As a result, when the pad is worn out, the pad can be appropriately replaced, so that the pad can be repaired.
Further, since the pad has a strength other than a part of the pad mounting portion formed by the metal plate and the elastic member, the pad can be firmly fixed to the pedal tread by a part other than the part. For this reason, since the pedal device does not require a fixing member such as a rivet, the number of parts and the number of assembling steps can be reduced. As a result, the workability of the assembly work is improved, the cost can be reduced, and the design can be improved.

  A pedal device according to a second aspect of the present invention is the pedal device according to the first aspect, wherein the pad attachment portion is formed at two corners of the pedal tread surface.

  According to the second aspect of the present invention, when the pad mounting portion formed only by the elastic member is formed at the two corners of the pedal tread so as to cover the pedal tread with the elastic member. In addition, since the portion formed only by the elastic member is elastically deformed, it can be easily assembled.

  In the pedal device according to the present invention, at least a part of the pad mounting portion with respect to the pedal tread is formed of only the elastic member, so that the portion formed only of the elastic member is elastically deformed, and the pad can be easily treaded. Can be attached to. As a result, it is possible to provide a pedal device that does not require a fixing member such as a rivet and is excellent in assembling.

  The pedal device according to the present invention includes, for example, a brake pedal, a foot-operated parking brake pedal, an accelerator pedal, a work vehicle, a two-wheeled vehicle, another vehicle, a machine, or the like that is stepped by a driver's legs in an automobile. Any device provided with a pedal 2 for stepping on can be used for all devices. Hereinafter, the case where it is used for a brake pedal of an automobile will be described as an example.

  The pedal tread surface 2a is a part for receiving the stepping operation force of the driver and rotating the pedal arm 2b about the support shaft, and is a plate arranged so as to be orthogonal to the stepping direction of the driver. It consists of a member. For example, the pedal tread surface 2a is formed in a substantially arc shape when a metal flat plate member formed in a substantially rectangular shape is viewed from the side. The pedal tread surface 2a has reinforcing portions 2c and 2c whose side sections are curved in a U-shaped groove when viewed from the side in the vicinity of the upper and lower end portions, and the reinforcing portions 2c and 2c are extended in the lateral direction. It is reinforced by and is prevented from bending in the left-right direction. At the outer peripheral edge of the pedal tread surface 2a, there is a flange portion 2d mounted in the engagement groove 5a having a U-shaped cross section that opens toward the center side direction of the pedal tread surface 2a at the outer peripheral portion on the back surface side of the elastic member 5. .

≪Pad configuration≫
The pad 3 is a member that is attached so as to cover the entire front side of the pedal tread surface 2a, and on which the driver's shoe sole is directly placed. The pad 3 is formed of a metal plate 4 as a skeleton member and an elastic member 5 as an anti-slip material for a driver's shoe sole. In the pad 3, at least a part of the pad mounting portion 3 a with respect to the pedal tread surface 2 a is formed by only the elastic member 5.

In the present embodiment, as shown in FIG. 1A, in the pad 3, the metal plate 4 is viewed from the front, for example, an upper peripheral portion 4 a disposed at the peripheral portion of the upper half, and the upper peripheral portion 4 a. Are formed in the shape of a substantially pentagonal frame formed by inclined portions 4b and 4b continuously formed in a V shape from the left and right sides of the left and right sides, and other portions are formed by the elastic member 5. .
For this reason, the pad attachment portion 3a for attaching the pad 3 to the pedal tread surface 2a is entirely formed by only the elastic member 5 by the inclined portions 4b and 4b formed in a V shape in FIG. Thus, it is formed to be easily bent and deformed along the inclined portions 4b and 4b. In particular, the corners 3d and 3d covering the left and right corners 2f and 2f of the pedal tread 2a are formed in a substantially triangular shape by the elastic member 5 alone.

  As shown in FIG. 1B, for example, the pad 3 is entirely formed of an elastic member 5 and is insert-molded with the surface of the metal plate 4 exposed at a part of the elastic member 5. . The metal plate 4 is installed on the upper side and the center of the pad 3, and only the elastic member 5 is installed on other parts.

≪Composition of metal plate≫
The metal plate 4 is made of, for example, a thin flat plate member made of aluminum, stainless steel, other metals, hard synthetic resin, or the like, and is formed in a substantially frame shape having a pentagonal shape when viewed from the front. The metal plate 4 is formed of a material different from that of the elastic member 5 and also has a function as a decorative plate due to its surface having a gloss or a pattern. Also serves as a core material. The metal plate 4 is embedded in a state in which the surface is exposed on the entire bottom surface of the annular groove 5 b formed on the surface side of the elastic member 5.
As shown in FIG. 1B, the upper side and the left and right sides of the metal plate 4 are formed to be curved in accordance with the outer peripheral shape of the pad 3. The inner peripheral edge of the metal plate 4 has a separation preventing portion 4 c that is formed in a state of biting into the elastic member 5.

≪Configuration of elastic member≫
The elastic member 5 is a member that forms the main part of the pad 3 and is formed of a relatively soft material that can be elastically deformed by hand force such as natural rubber, synthetic rubber material, synthetic resin material, and the like. Has been.
An annular groove 5b in which the metal plate 4 is embedded in an upper half portion and an inner side of the annular groove 5b are formed along a predetermined interval on the surface side of the elastic member 5 with which the shoe sole of the driver contacts. A substantially triangular inner annular groove 5c and a plurality of inclined grooves 5d provided obliquely so as to expand from the central lower end toward the left and right upper direction are formed. Thus, since the surface of the elastic member 5 is uneven with a plurality of grooves formed in an oblique direction, it also functions as an anti-slip material and a shock absorber for the shoe sole. Furthermore, there is also a function of making the elastic member 5 easier to beat when the pad 3 is attached to the pedal tread 2a.
On the back surface side of the elastic member 5, a winding engagement part 5 e formed in a U shape from the outer peripheral edge toward the center side, and an engagement groove 5 a formed by the winding engagement part 5 e , Is formed.

≪Operation of pedal device≫
Next, the operation of the pedal device 1 according to the embodiment of the present invention will be described along the assembly procedure with reference to FIGS. 1 (a) and 1 (b).

  First, the pedal tread 2a is welded to the tip of the pedal arm 2b to integrally form the pedal 2. Next, the metal plate 4 is inserted into the mold, and a material for forming the elastic member 5 is poured into the mold to mold the pad 3 made of a metal-containing resin product. Thereby, the metal plate 4 is insert-molded in the elastic member 5, and the metal plate 4 and the elastic member 5 are integrally formed.

The flange portion 2d on the upper side of the pedal tread surface 2a is inserted into the engagement groove 5a on the upper portion of the elastic member 5 from the lower side and engaged.
Next, hold the corners 3d, 3d at the lower left and right ends of the elastic member 5 with both hands, and further wrap in the part where the corners 3d, 3d are bent so as to warp in the front side direction (arrow X direction). The engaging portion 5e is bent outward (arrow Y direction) so that the corners 3d, 3d of the left and right lower portions are covered with the corners 2f, 2f of the pedal tread 2a, and the engagement groove 5a is formed on the pedal tread. Fit into the flange 2d of 2a. In this way, the pad 3 can be attached to the pedal tread 2a.

  At the time of this attachment, since the lower half of the pad 3 is formed of only the elastic member 5, it can be easily warped and bent. In particular, since the corners 3d and 3d (lower both ends) of the pad 3 are formed so that two triangles are connected in series, the corners 3d and 3d are bent with both hands and bent. It is possible to bend easily. For this reason, when attaching the pad 3 so as to cover the corners 2f, 2f of the pedal tread surface 2a, the portion where the lower winding locking portion 5e is easily deformed, so that the fitting operation is easily performed.

  As described above, even the pad 3 having the so-called sports pad having the metal plate 4 can be assembled by hand as in the case of assembling the conventional normal pad 300 (see FIG. 3) to the pedal 200. Property can be improved.

  The pad 3 assembled to the pedal tread 2a in this way is formed in a state in which the upper half and the lower part of the center are reinforced by providing a core with a metal plate 4, and has a separation preventing part 4c. ing. For this reason, the pad 3 prevents the metal plate 4 from being separated from the elastic member 5 or the elastic member 5 from being deformed, so that the metal plate 4 and the elastic member 5 are fixed by a fixing member such as a rivet. Is no longer necessary. As a result, the number of parts and the number of assembling steps can be reduced, the cost can be reduced, and the design can be improved.

≪Modification≫
The present invention is not limited to the above-described embodiment, and various modifications and changes can be made within the scope of the technical idea. The present invention extends to these modifications and changes. Of course.

Next, a modified example of the pedal device according to the embodiment of the present invention will be described with reference to FIGS.
Drawing 2 is a figure showing the modification of the pedal device concerning the embodiment of the present invention, (a) is a front view and (b) is a BB sectional view of (a).

  In the above-described embodiment, as shown in FIGS. 1A and 1B, the entire pad 3 is integrally formed with the metal plate 4 and the elastic member 5. However, the pad 3 is limited to this. Not a thing.

2 (a) and 2 (b), the pad 30 of the pedal device 10 is formed in two parts by separating the upper portion 30b and the lower portion 30c, and the pad 30 has a lower portion that is more easily worn than the upper portion 30b. 30c may be formed only by the elastic member 50 (lower elastic member 50B).
If formed in this way, the pad 30 has the same surface shape as the pad 3 of the above embodiment, but when the lower elastic member 50B is worn, the lower 30c is separated from the upper 30b, and Only the lower elastic member 50B, which is a part, can be exchanged.

In this case, the upper portion 30b of the pad 30 is reinforced by integrally forming the upper elastic member 50A and the metal plate 40 functioning as a core material and a decorative plate by insert molding or the like as in the above embodiment. . The upper portion 30b is engaged with the engagement groove 50Aa of the upper elastic member 50A by inserting the flange portion 20d of the pedal tread surface 20a into the engagement groove 50Aa and in the recess 20e formed in the outer peripheral portion of the pedal tread surface 20a. It is fixed by engaging the engaging projection 50Af.
The metal plate 40 is formed in a pentagonal substantially frame shape like the metal plate 4 of the above-described embodiment, and has inclined portions 40 b and 40 b formed in a mountain shape toward the lower center portion of the pad 30. Yes. The lower end portion 40c of the metal plate 40 is bent so as to cover the lower outer peripheral edge of the pad 30 on the upper portion 30b side and to be attached to the upper end portions of the pedal tread 20a and the lower portion 30c of the pad 30.

And the lower part 30c of the pad 30 is inserted in the lower part of the inclination parts 40b and 40b of the upper part 30b, and is connected continuously.

The lower portion 30c is engaged with the engaging groove 50Ba of the lower elastic member 50B by inserting the flange portion 20d of the pedal tread surface 20a into the engaging groove 50Ba and formed in the recess 20e formed in the outer peripheral portion of the pedal tread surface 20a. It is fixed by locking the locking projection 50Bf.

  The pad mounting portion 30a formed in this way has an engagement groove 50Ba and a winding engagement portion 50Be formed in the lower left and right corners 30d, 30d of the pad mounting portion 30a, and a diagonal line of the pedal tread surface 20a. Since the upper corners 20f and 20f are formed in a substantially right triangle shape in plan view, the structure is easy to bend so as to warp in the direction of the hypotenuse of the substantially right triangle (arrow X direction). . Further, since the locking convex portion 50Bf is also formed at the upper left and right end portions of the lower elastic member 50B, it is bent so as to spread outward (arrow Y direction) and is easily engaged with the concave portion 20e.

  For this reason, since the lower elastic member 50B is easy to bend and bend, the lower flange portion 2d of the pedal tread surface 2a is easily engaged with the engagement groove 50Ba while the winding engagement portion 50Be is warped outward. It has become. For this reason, the assembling work for assembling the pad 30 (lower elastic member 50B) to the pedal tread 20a is improved.

Note that the pad attachment portion 30a may be separately provided at two corners 30d and 30d on the diagonal line of the pedal tread 20a. In this case, for example, the mountain-shaped portion 40d of the metal plate 40 may be further extended to the lower side, and the lower elastic member 50B may be separated into a state in which a right triangle is formed on the left and right.
In this way, when either one of the corners 30d of the lower elastic member 50B, which is the most easily worn portion of the pad 30, is worn, only one of the lower elastic members can be replaced.
