Abstract

A kind of be used for bicycle accessory for example child's bicycle push away the anchor clamps of handle.These anchor clamps comprise first and second adaptor unions that are used for being connected on the bicycle pillar and are connected on the annex.Two parallel arms interconnect for example being rigidly connected on the seat pillar at the one end, interconnect so that coupling rotationally at the other end.Another degrees of rotation can be provided between adaptor union.

Description

The anchor clamps that are used for bicycle handle

Technical field

The present invention relates to the anchor clamps of the annex that is used to move, particularly, but not only relate to connect child's bicycle and this bicycle push away handle the time anchor clamps that use.

Background technology

Usually, the adult can promote the children on the bicycle easily, when for example children feel tired before the end of going on a tour, perhaps is like this when children learn by bike.Can use a series of handle device that pushes away to achieve this end.These push away the handle device and are connected in every way on two-wheeled and the tricycle, and alerting ability in various degree is provided.

Summary of the invention

An object of the present invention is to provide a kind of improvement anchor clamps that are used for bicycle accessory, the another kind of scheme of existing anchor clamps perhaps is provided at least.This annex is a handle normally, can promote bicycle by this handle.

Therefore, one aspect of the present invention is to be used for the anchor clamps of bicycle accessory, these anchor clamps have two parallel arms, these two arms interconnect to be formed for being rigidly connected to first adaptor union on the bicycle seat pillar at the one end, are interconnected to form at the other end to be used for second adaptor union of coupling rotationally.

In one embodiment, first adaptor union and arm integral body form one substantially around the annulation of pillar.This annulation can comprise an articulated section, and it is also closed to hold pillar that this articulated section can be opened arm.Bolt that passes the arm of adjacent rings thing arm is coupled together and annulation be fixed on pillar around.Preferably, second adaptor union is set to a pin that passes arm, is used for an end of annex is remained between the arm.

In another kind of embodiment, arm comprises a rotary engaging member, and this rotary engaging member forms on the arm between first and second adaptor unions.This rotary engaging member is separated each arm and is comprised a pair of lateral part that links together by a rivet or analogue.Second adaptor union and fastener provide first and second rotational freedoms of relative proper motion car for annex.

The present invention also is an annex that is used for bicycle, and this annex comprises the anchor clamps that are defined as above.

Description of drawings

With reference to the accompanying drawings the preferred embodiments of the present invention are described, wherein:

Fig. 1 shows of being connected on the bicycle and pushes away handle;

Fig. 2 a shows first anchor clamps that are used between handle and the bicycle;

Fig. 2 b shows the details of clamp member among Fig. 2 a;

Fig. 3 shows second anchor clamps with other alerting ability;

Fig. 4 shows another kind of version;

Fig. 5 shows and is used for the telescopic handle that pushes away that uses with anchor clamps, and

Fig. 6 shows a kind of selectable handle.

The specific embodiment

With reference to these accompanying drawings, will be understood that the present invention can implement in many ways.These embodiment just are described by example.

Fig. 1 shows a kind of child's bicycle 10 with annex, and this attachment version pushes away handle 11 for being connected by anchor clamps 12 on the bicycle.Preferably, these anchor clamps are connected an end of handle and support between the pillar at seat 13.These anchor clamps will make handle pivot in the plane of bicycle at least, preferably can also rotate in the both sides of bicycle.This handle can be used by the adult, and children's father and mother for example promote and/or keep having on the seat children's bicycle upwards upright.Bicycle has two main wheels and two training wheels in the present example, although the handle of this common type can be used in the wider bicycle.

Fig. 2 a shows the anchor clamps that are used for Fig. 1 handle, but these anchor clamps also use or are connected on the different piece of bicycle with a series of other annexes.These anchor clamps comprise two arm 20 and fasteners 23 of having

adaptor union

21 and 22 at every end.Adaptor union 21 is annulations that connect arm, be connected on the seat pillar in the use, and adaptor union 22 is quick release pin, and this quick release pin is passed two arms so that provide connection for an end of handle.Fastener 23 is rapid release bolts, also passes two arms, and it is used for two arms are linked together between two adaptor unions, thus with annulation be tightened in seat pillar around.In use, anchor clamps remain attached on the seat pillar usually, and handle is connected on the anchor clamps, can remove from anchor clamps when needing.The adaptor union 22 that handle can make to axle rotates in a plane.

Fig. 2 b provides the details of the parts of anchor clamps among Fig. 2 a.Two arms 20 are parallel to each other and form with the annulation that forms adaptor union 21 is whole.Fastener 23 is traditional bolt system in the present example, and this fastener 23 passes the hole 27 on the arm, this bolt system comprise bar 24, with the interactional cam washers of bar (cam washer) 25, and packing ring/nut conjunction 26.Adaptor union 22 is spring-loaded pins, and this spring-loaded pin passes the hole 28 on the arm and kept by the key on the end of pin 29.The head that rotates pin allows key to pass at least one hole 28, and this pin can withdraw from from arm to small part like this.This part of anchor clamps also has various ways, but wishes that it connects simply and safely fast or removes handle.

Fig. 3 shows a kind of optional anchor clamps that are used for Fig. 1

handle.Adaptor union

21,22 is identical with fastener 23 anchor clamps common and among Fig. 2.Yet a kind of complicated more arm structure provides its other change degree when using handle, shown in circular arrow now.Arm is blocked by the lateral part now, and this lateral part forms the rotary engaging member 30 perpendicular to the pin of adaptor union 22.The arm structure comprises that one keeps the U-shaped part 31 of adaptor union 22 and the L shaped part 32 of a contiguous fastener 23.U-shaped and L shaped part lean and keep together to form the rotational engagement part by a rivet 34.

Fig. 4 shows another kind of the variation, and this variation is suitable for being used in Fig. 1,2 or 3 the anchor clamps.Adaptor union 40 comprises an annulation with the same in the past, but also comprises an articulated section 41, this articulated section 41 to make annulation to open now and need not to remove fastener 23.

Fig. 5 shows one in more detail than Fig. 1 and pushes away handle.In this example, handle comprises an angled handle portion 50 and two

telescopic parts

51,52, and these two

telescopic parts

51,52 can remain in the handle.Operate telescopic part by pin and hole 53 in common mode, one of them pin is shown in the decomposition view.Also show an end pieces that engages with anchor clamps 54.Adaptor union 22 passes the hole 55 on the end pieces.

Fig. 6 shows a kind of optional handle that pushes away, and this pushes away handle and has crooked handle portion 60.
