SECURING DEVICE FOR SEUCRING BICYCLE FRAME TO BICYCLE CARRY RACK

A securing device includes a base connected with a bicycle carry rack. A belt unit includes a body and a locking member. A belt is connected to the body and extends through a path in the body. The locking member is pivotably connected to the body. The locking member is a cam. A fixed part is connected to the body and an opening is defined between the fixed part and the locking member. The first end of the belt is fixed to the body and the second end of the belt extends through the path and the passage, and entering through a through hole in the body and then goes out from the opening so as to clamp the bicycle frame between the base and the body. By pivoting the locking member, the opening becomes larger to release the belt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring toFIGS. 1 to 3, the securing device of the present invention comprises a base10and a belt unit20. The base10is an elongate member and has an elongate installation hole11defined longitudinally therethrough so that the upright tube71of the bicycle carry rack70extends through the installation hole11such that the base10is connected with the bicycle carry rack70as shown InFIGS. 4 and 7. The base10has a contact side12and a belt side13on two sides thereof. The belt side13has a passage14defined therethrough.

The belt unit20comprises a locking unit30and a belt50. The locking unit30has a rectangular body31and a locking member40which is used to secure the belt50. The body31has a path23defined longitudinally therethrough as shown inFIGS. 3 and 5, and the body31has an inside and an outside, wherein the path23is located between the inside and the outside. The inside of the body31has a curved contact face33which is an anti-slip face.

The body31of the locking unit30comprises a first hole34, an elongate second hole341and a through hole342in sequence. A fixed member35is located beside the second hole341and the locking member40is located beside the fixed member35.

The locking member40is pivotably connected to one end of the contact face33and has a head41on one end thereof. The head41has a pin411extending eccentrically therethrough so that the locking member40is a cam. The head41has a short side42and a long side43. The distance from the short side42to the pin411is shorter than the distance from the long side43to the pin411. A fixed part44is connected to the body31and located opposite to the contact face33. An opening45is defined between the fixed part44and the head41. The opening45communicates with the contact face33, the through hole342defined in the body31and communicates with the opening45.

The first end of the belt50is fixed to the fixed member35and the second end of the belt50extends through the path32and the first hole34, the second end of the belt50then extends through the passage14of the base10and enters into the through hole342and extends through the opening45of the body31. By this arrangement, the belt50goes along the outside of the base10as shown inFIGS. 1 and 2.

As shown inFIGS. 4 and 7, the upright tube71of the bicycle carry rack70extends and secured to the installation hole11so as to connect the base10to the bicycle carry rack70. When securing a bicycle to the bicycle carry rack70, as shown inFIGS. 2,5and6, the seat tube60is in contact with the contact side12of the base10, and the user pulls the belt50to contact the contact face33against the other portion of the seat tube60. In other words, the seat tube60is clamped in two directions by the contact side12of the base10and the contact face33of the body31.

After the belt50is tightened, the locking member40is pivoted about the pin411, and the long side43is moved toward the fixed part44, so that the opening45is narrower and is smaller than the thickness of the belt50. The belt50is then clamped by the long side43and the fixed part44. Therefore, the seat tube60is well secured.

When the user wants to remove the bicycle from the bicycle carry rack70, the locking member40is pivoted about the pin411in opposite direction, and the short side42is moved toward the fixed part44, so that the opening45becomes larger so that the belt50can be moved freely in the path32, the through hole342and the opening45. This enlarges the area that the belt50clamps the seat tube60, or the belt50can be pulled from the locking unit30to allow the user to remove the bicycle from the bicycle carry rack70.

FIG. 6shows that a larger size of the seat tube601is clamped between the contact side12of the base10and the contact face33of the body31. Because the contact face33is a curved face so that the larger size of the seat tube601is clamped at sufficient contact area. By cooperation with the locking unit30and the belt50, the seat tube601is well secured.
