Pedal assembly

Abstract

A pedal assembly has a base and a pedal. The pedal is pivotally mounted on the base and has two mounting sleeve mounted between the base and the pedal. A resilient element is mounted between the mounting sleeves. A retaining element is secured to the base. Each mounting sleeve has a rubbing surface abutting against the pedal. Accordingly, gaps between the mounting sleeves and the pedal due to attrition will be automatically eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1 and 2, the pedal assembly (10) in accordance with the present invention comprises a base (11), an operational beater (13) and a pedal (12).

The base (11) is mounted on the ground and has a mounting portion (110) and a threaded hole (111). The mounting portion (110) has a surface and a channel having two ends longitudinally formed on the surface. The threaded hole (111) is formed in the base (11) at a position beside the mounting portion (110).

The beater (13) is pivotally mounted on the base (11) and is connected with two springs (130) to return the beater (13) when the beater (13) is pivoting.

With further reference to FIG. 3, the pedal (12) is inclinedly connected to the base (11) and has an actuating end, a pivotal end, a shaft (120), two mounting sleeves (21), a resilient element (23), two optional spacers (30) and a retaining element (22).

The actuating end is connected to the beater (13) via a chain to drive the beater (13) to rotate and return to an original position with the resilient force provided by the springs (130).

The pivotal end has two sides and two ears (121) formed on the sides separately for receiving the mounting portion (110), each one of the ears (121) has a side surface (122) and a mounting hole (123) defined through the ears (121) respectively and aligning to each other.

The shaft (120) is rotatably mounted in the channel and has an outer diameter and two ends extending into the mounting holes (123) of the ears (121) respectively.

The mounting sleeves (21) are mounted around the shaft (120) near the two ends of the shaft (120), are located in the two ends of the channel of the base (11) and correspond to the ears (121), respectively. Each one of the mounting sleeves (21) has a through hole (210) and a flange (211). The through hole (210) is mounted around one end of the shaft (120) and has an inner diameter larger than the outer diameter of the shaft (120), such that the pedal (12) is pivotally connected to the base (11) with shaft (12) and the mounting sleeves (21). The flange (211) abuts with the corresponding ear (121) and has a rubbing surface (212) corresponding to and contacting with the side surface (122) of the corresponding ear (121).

The resilient element (23) may be a spring, is mounted around the shaft (120) between the mounting sleeves (21) and has two ends abutting respectively against the mounting sleeves (21) to push the rubbing surfaces (212) on the flanges (211) of mounting sleeve (21) to abut against the ears (121) on the pedal (12).

The spacers (30) are mounted on the shaft (120) between the rubbing surfaces (212) of the mounting sleeves (21) and the side surfaces (122) of the ears (121).

The retaining element (22) is inverse L-shaped, is secured to the base (11) and has a fixing hole (220) and a screw (221). The fixing hole (220) is formed through the retaining element (22) and aligns with the threaded hole (111) in the base (11). The screw (221) extends through the fixing hole (220) and is screwed into the threaded hole (111) to mount the retaining element (22) securely on the base (11) and hold the mounting sleeves (21) in position.

With further reference to FIG. 4, when gaps occur between the side surfaces (122) of the ears (121) and the rubbing surfaces (212) of the mounting sleeves (21) due to attrition, the retaining element (22) can be detached from the base (11) such that the resilient element (23) will provide a biasing force to push the rubbing surfaces (212) of mounting sleeves (21) to abut closely against the side surfaces (122) of the ears (121). Accordingly, the gaps may be automatically eliminated, such that the operation of the pedal assembly (10) in accordance with the present invention is still kept at a stable condition after a long time of use.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
