Abstract

A quick release device for a pedal includes a spindle, a connecting unit connected to the spindle, and a quick release mechanism connected to the connecting unit. The spindle has a protrusion extending from one end thereof and an annular groove defined in an outer peripheral thereof The connecting unit has a receiving hole defined therein, a guiding hole defined in a lateral thereof and communicated with the receiving hole, and a retaining hole defined therein and communicated with the receiving hole. The quick release mechanism includes a rod partially received in the guiding hole and a spring biased against the rod toward the receiving hole. In assembly the protrusion engages with the retaining hole and the rod engages with the annular groove.

Claims

1. A quick release device for a pedal, comprising:

a spindle having a protrusion extending from one end thereof and an annular groove defined in an outer peripheral thereof;

a connecting unit connected to the spindle, the connecting unit having a receiving hole defined therein for partially receiving the spindle, the connecting unit having a guiding hole defined in a lateral thereof and communicated with the receiving hole, the connecting unit having a retaining hole defined therein and communicated with the receiving hole; and

a quick release mechanism connected to connecting unit, the quick release mechanism comprising a rod partially received in the guiding hole and a spring biased against the rod toward the receiving hole;

whereby in assembly the protrusion engages with the retaining hole and the rod engages with the annular groove.

2. The quick release device for a pedal as claimed in claim 1, wherein the rod has a shank portion and an enlarged head portion extending from one end thereof, a diameter of the head portion being substantially equal to a width of the annular groove.

3. The quick release device for a pedal as claimed in claim 2, wherein the quick release mechanism further comprises a fastener screwed to the guiding hole, the fastener having a through hole defined therein for passing the shank portion.

4. The quick release device for a pedal as claimed in claim 1 further comprising a housing connected to the rod and a pin passing through the housing and the rod, wherein the rod moves with the housing along the guiding hole when pulling the housing.

5. The quick release device for a pedal as claimed in claim 1, wherein the quick release mechanism further comprises a ring sleeved on the rod, wherein the ring is made of soft materials and lubricated.

6. The quick release device for a pedal as claimed in claim 1, wherein the spindle has a threaded portion formed in one end thereof for adapting to be mounted to the pedal.

7. The quick release device for a pedal as claimed in claim 1, wherein the connecting unit has a threaded portion formed in one end thereof for adapting to be mounted to a crank.

8. The quick release device for a pedal as claimed in claim 1, wherein the protrusion is in a shaped of polygon and the retaining hole is complementary to the protrusion for engaging with the protrusion.

9. The quick release device for a pedal as claimed in claim 1, wherein the spindle further has a first incline surface being adjacent to one side of the annular groove.

10. The quick release device for a pedal as claimed in claim 1, wherein the connecting unit further has a second incline surface being formed between the receiving hole and the retaining hole.
