Bicycle attachment handle connection device

The present invention relates to bicycle steering devices, and more particularly to a bicycle attachment handle attachment device.

In a long-distance race of a bicycle, the rider must grasp the grip of the bicycle to control the direction and hold the upper body by hand. However, after a long ride, the fatigue of the driver gradually increased, and gradually unable to support the weight of the upper body. Therefore, an additional handle mounted on the bicycle grip has been developed on the market. Since the additional handle is located between the two grips, the rider can support the weight of the upper body with a vertical force, reducing the burden on the hand.

One aspect of the present invention provides a connecting device for a bicycle additional handle, comprising a pressing member, a gasket, a pressing seat and a fastener. The pressing device pivots the pressing member, and the gasket is between the pressing member and the pressing seat and includes two concave curved surfaces, and the pressing member cooperates with one of the concave curved surfaces of the gasket to press a bicycle grip. The other concave concave surface of the pressing seat and the gasket is pressed against an additional handle, and the fastener detachably connects the pressing member and the pressing seat, thereby connecting the bicycle grip and the additional handle.

According to still another aspect of the present invention, a bicycle attachment handle connecting device includes a pressing seat, a gasket, a pressing member and at least one fastener. The pressing seat has a recess for the passage of an additional handle. The gasket is used to cover the groove of the pressing seat and includes two concave curved surfaces, one of which is concave The curved surface faces the pressing seat for tightening the additional handle. The pressing member accommodates the gasket between the pressing seat and the pressing member so that one bicycle grip can pass between the gasket and the pressing member, and the other concave curved surface faces the pressing member for forcing Tight the bicycle grip. The fastener detachably connects the pressing member and the pressing seat. In this way, the pressing piece and the gasket are pressed against the bicycle grip, and the gasket and the pressing seat are tightly attached to the handle.

1 is a perspective exploded view of a connecting device according to an embodiment of the present invention. In this embodiment, the attachment device includes a pressing member 100, a pressing seat 200, a spacer 300, and a fastener 400. The pressing member 100 is opposite to the pressing seat 200 and constitutes a clamping device. The gasket 300 is received between the pressing member 100 and the pressing seat 200. The fastener 400 detachably connects the pressing member 100 with the pressing seat 200.

2 is a perspective assembled view of the connecting device of FIG. 1 connecting a bicycle grip 900 and an additional handle 800. Fig. 3 is a cross-sectional view taken along line 3-3 of Fig. 2. In use, the bicycle handle 900 is sandwiched by a bicycle handle 900 and an additional handle 800, and the additional handle 800, the spacer 300 and the bicycle grip 900 are clamped from the outside by the clamping device, thereby connecting the bicycle grip 900 with Additional handle 800. In other words, the additional handle 800 is clamped by the pressing seat 200 and the spacer 300, and the pressing member 100 and the spacer 300 sandwich the bicycle grip 900. The fastener 400 connects the pressing member 100 and the pressing seat 200 to fix the pressing member 100 and the pressing seat 200, and clamps the additional handle 800, the gasket 300 and the bicycle grip 900 to connect the bicycle grip 900 with Additional handle 800. And the gasket 300 can avoid the bicycle grip 900 and the additional handle 800 Damage caused by collision or wear.

Referring to FIG. 1 , in one embodiment of the present invention, the pressing seat 200 can have a groove 210 for covering the groove 210 , and the pressing member 100 can accommodate the gasket 300 in the pressing seat. 200 between the pressing member 100. In use, the additional handle 800 is passed through the recess 210 and the bicycle grip 900 is passed between the spacer 300 and the biasing member 100. When the fastener 400 connects the pressing member 100 and the pressing seat 200, the pressing member 100 and the gasket 300 can be forced to the bicycle grip 900, and at the same time the gasket 300 and the pressing seat 200 are forced to attach the handle 800.

In one embodiment of the invention, the pressing member 100 is pivotally biased to the seat 200. Thereby, the pressing member 100 and the pressing seat 200 are relatively rotatable, so that the connecting device is more easily connected to the additional handle 800 and the bicycle grip 900, and is also easier to disassemble.

In one embodiment of the present invention, the spacer 300 may include two concave curved surfaces 310, and the two concave curved surfaces 310 face the pressing member 100 and the pressing seat 200, respectively. In use, the two concave curved surfaces 310 cooperate with the pressing member 100 and the pressing seat 200 to press the bicycle grip 900 and the additional handle 800, respectively.

In one embodiment of the invention, the pressing member 100 can also include a concave curved surface 110, and the concave curved surface 110 faces the spacer 300. In use, the concave curved surface 110 can force the bicycle grip 900 with the gasket 300.

In one embodiment of the present invention, the connecting device may include two pins 500, and the gasket 300 has two gasket perforations 320, and the pressing seat 200 has two pressing seat perforations 220. Each of the pins 500 extends through the shim perforations 320 and the perforating seat perforations 220 to position the shim 300 in the tightening seat 200. Thereby, the spacer 300 can be positioned in the pressing seat 200 to prevent the spacer 300 from falling and lost.

In one embodiment of the invention, the latch 500 and the shim perforation 320 also have an activity margin that allows the shim 300 to move relatively small relative to the clamping seat 200. The technique of having an activity margin between the latch 500 and the spacer perforation 320 allows the latch 500 to be smaller than the spacer perforation 320; and when the latch 500 is a cylinder and the spacer perforation 320 is a circular hole, the diameter of the plug 500 can be made smaller than the pad. The diameter of the sheet perforation 320. By the technique that the spacer 300 can relatively urge the seat 200 to be displaced, it is also possible to use the additional handle 800 of different sizes for use with the bicycle grip 900.

In one embodiment of the invention, the fastener 400 is a threaded member for locking the tensioning member 100 with the clamping seat 200. The term threaded knot refers to a threaded joint such as a screw, a bolt, a stud, a nut or any combination of the above. The pressing member 100 and the pressing seat 200 respectively have a screw hole 120, 230 for the fastener 400 to be locked.

Fig. 4 is a perspective view showing an arm support 600 provided on the pressing member 100 of Fig. 2. In one embodiment of the invention, an arm support 600 can also be disposed on the pressing member 100. When the user uses the additional handle 800, the arm can be placed on the arm support 600 to provide more stable support to reduce the burden on the arm.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
