Description

Foldable handlebar for scooter

Technical Field

The utility model relates to a collapsible hand (hold), especially a collapsible hand (hold) for scooter.

Background

The scooter is widely used in urban life due to the advantages of portability, small size and the like, and particularly the foldable scooter is popular among people.

When the foldable scooter is not used, the foldable scooter can be folded so as to be convenient to store and carry, when the foldable scooter is folded, the foldable scooter on the market at present usually adopts a design of partially folding the operating rod and the pedal, and a handle part which is a part with the largest transverse dimension in the foldable scooter is expected to be folded, so that the portability and the small size of the foldable scooter are further improved.

Structures have been developed to fold the handle. The general features of such a structure are: a handle rotatably coupled to the crossbar (or the handle attached to a rotating member which in turn is rotatably coupled to the crossbar), a slidable sleeve member that fits over the crossbar and the handle, and a spring positioned inside the slidable sleeve member and attached to the handle. In the unfolded state of the foldable handlebar for sliding use, the slidable sleeve member is sleeved over the cross bar and the handlebar to prevent rotation of the handlebar relative to the cross bar. When it is desired to collapse the handle for storage and carrying, the sleeve member may be pulled outwardly, sliding it completely past the position of the cross bar rotatably coupled with the handle (or the rotating member in the case of a handle attached to the rotating member), whereupon the spring positioned inside the slidable sleeve member and attached to the handle is compressed and acts to prevent further outward pulling of the sleeve member. At this time, the handle (or the rotating member) obtains a degree of freedom of downward rotation, and the user can simply rotate the handle (or the rotating member) downward by 90 degrees, thereby bringing the foldable handle into its folded state. A more detailed description of the above structures can be found in CN105292358A, CN202138477U and CN 109436168A.

The most common foldable handlebars of this type have several problems: first, in order to collapse the foldable handlebar, the user needs to pull the foldable handlebar outwards with force, which operation may cause certain difficulties for users with weak force (such as children), depending on the spring constant of the spring positioned inside the slidable sleeve member and attached to the handlebar, and may present problems of robustness and robustness due to the relative pulling between such members; second, there is a general lack of means to securely hold the vertically downwardly oriented handle in this vertically downward orientation when the foldable handle is in the collapsed state.

Thus, there is still much room for improvement.

Detailed Description

Hereinafter, the foldable handle according to the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

It is understood that the drawings illustrate only preferred embodiments of the invention by way of example. Directional terminology, such as "upper", "lower", "front", "rear", "inner", "outer", etc., used herein is for the purpose of illustration only and is not intended to be limiting.

First, fig. 1 to 4 are referred to. The foldable handlebar 100 has: a vertical rod 1; a cross tube 2 attached to the top end of the vertical rod 1; stop members 21, 22, a portion of which stop members 21, 22 are inserted into respective ends of the cross tube 2 and fixed therein (e.g., by various known means such as screws, welding, adhesives, etc.), the remaining portion of the stop members 21, 22 extending outside the cross tube 2, and the stop members 21, 22 having at least one stop formation 21A, 22A, respectively; a handle portion 51, 52, the handle portion 51, 52 having a handle head 511, 521, respectively, the handle head 511, 521 being rotatably coupled to the respective stop member 21, 22, the handle head 511, 521 having at least one stop formation 511A, 521A, respectively, wherein the respective stop formation 21A, 22A of the stop member 21, 22 is interengaged with the respective stop formation 511A, 521A of the handle head 511, 521, respectively; sleeves 31, 32, which sleeves 31, 32 are each rotatably journalled about the axis of the transverse tube 2 on one end of the transverse tube and on the portion of the respective stop member 21, 22 extending out of the transverse tube 2, the sleeves 31, 32 having a cut-out 71, 72, respectively, on the peripheral edge relative to the outermost end of the vertical rod 1, the cut- outs 71, 72 being dimensioned to allow a rotational movement of the handle head therethrough, allowing the handle portions 51, 52 to be rotated downwards when the cut- outs 71, 72 are oriented downwards, and the bottoms of the sleeves 31, 32 engaging the bottoms of the handle heads 511, 521, respectively, when the cut- outs 71, 72 are not oriented downwards, so as not to allow the handle portions 51, 52 to be rotated downwards. The outer ends of the handle portions 51, 52 may be sleeved with handle sleeves 41, 42 to increase the gripping comfort of the user.

The handlebar head and the stop member each include at least one corresponding engagement formation and are rotatably engaged with one another by the engagement formations, in this context lugs as an example of an engagement formation.

Preferably, the stop members 21, 22 each extend outwardly with two apertured lugs (not shown), the handle heads 511, 521 each have a through hole, and the handle heads 511, 521 can be inserted between the two apertured lugs of the respective stop members 21, 22 and the through holes of the handle heads can be aligned with the holes of the lugs so that the handle heads 511, 521 can be rotatably coupled to the stop members 21, 22 and, in turn, to the cross tube 2 using the pins 11, 12. Although the stop members 21, 22 described herein each have two lugs with holes extending outwardly therefrom, the present invention is not limited thereto. For example, in another embodiment, the handle head may have two lugs with holes, and the stop member has no lugs but has through holes, and the stop member may be inserted between the two lugs with holes of the respective handle head and pinned. For example, in yet another embodiment, the handle head and the stop member each have a lug with a hole, and the lug of the handle head and the lug of the stop member may be engaged with each other in a corresponding manner and pinned

Preferably, the limit formations 511A, 521A of the handle heads 511, 521 are recesses having a particular shape and the limit formations 21A, 22A of the limit members 21, 22 are protrusions.

Alternatively, the stop formations 511A, 521A of the handle heads 511, 521 are protrusions and the stop formations 21A, 22A of the stop members 21, 22 are recesses having a particular shape.

Preferably, when the handle portions 51, 52 are rotated downwardly to be parallel with the vertical rod 1, the respective stop formations 21A, 22A of the stop members 21, 22 are forced to slide out of the respective stop formations 511A, 521A of the handle heads 511, 521, respectively, and the stop formations 21A, 22A engage the peripheral walls of the handle heads 511, 521, respectively, so that the handle heads 511, 521 cannot swing freely, thereby securely holding the handle heads 511, 521 and the handle portions 51, 52 in place.

Alternatively, when the handle portions 51, 52 are rotated downwardly to be parallel with the vertical rod 1, the respective stop formations 511A, 521A of the handle heads 511, 521 are forced to slide out of the respective stop formations 21A, 22A of the stop members 21, 22, respectively, and the stop formations 511A, 521A engage the peripheral walls of the stop members 21, 22, respectively, so that the handle heads 511, 521 cannot swing freely, thereby securely holding the handle heads 511, 521 and the handle portions 51, 52 in place.

Preferably, the sleeves 31, 32 have slit openings 61, 62 extending in the circumferential direction, respectively, and guide members 81, 82 and positioning members 91, 92 are inserted at both ends of the respective slit openings 61, 62, respectively.

Preferably, the guide members 81, 82 are pins, but may also be designed as guide members that are not visible from the appearance. The positioning members 91, 92 are preferably spring-loaded pushbuttons that can be depressed.

Since the structure of the present invention is bilaterally symmetric about the vertical rod 1 as the axis of symmetry, the following detailed description will be described with each left side member (the member of the left half in fig. 1, such as the sleeve 31, etc.) as an example for the sake of brevity.

Preferably, the arc length between the guide member 81 and the respective positioning member 91 is one quarter of the circumference of the sleeve 31 so that the cut-out 71 can be rotated between a forward orientation (or rearward orientation) and a downward orientation.

Taking the example where the limit structure 21A of the limit member 21 is the protrusion 21A and the limit structure 511A of the handle head 511 is the recess 511A, when the foldable handle 100 is in the folded configuration, the handle portion 51 is parallel to the vertical rod 1, and the limit structure 21A of the limit member 21 engages the outer peripheral wall of the handle head 511, so that the handle portion 51 cannot swing freely, but at the same time, when the handle portion 51 is forcibly turned upward, the limit structure 21A of the limit member 21 is forced to slide into the corresponding limit structure 511A of the handle head 511, and then the handle portion 51 can be returned to be coaxial with the transverse tube 2.

The method of operation of the foldable handlebar 100 will be described in detail with reference to fig. 5-9, wherein the stop formation 21A of the stop member 21 is a protrusion 21A and the stop formation 511A of the handlebar head 511 is a recess 511A. As shown in fig. 5, the foldable handlebar 100 is initially in an unfolded state, i.e., with the handlebar portions 51, 52 coaxial with the cross tube 2. In the following, again taking each left side member as an example, the right side member operates in exactly the same way. The guide member 81 and the positioning member 91 abut against the two ends of the slot opening 61, respectively, so that the sleeve 31 cannot rotate about its axis, and the bottom of the sleeve 31 engages the bottom of the handle head 511, thereby not allowing the handle portion 51 to rotate downward, with the cut-out 71 oriented forward or rearward. The user can normally use the foldable handlebar 100 for sliding while the guide members 81, 82 and the positioning members 91, 92 abut against the respective ends of the slot openings 61, 62, respectively, so that both the handlebar portions 51, 52 cannot be turned downward.

When it is desired to collapse the foldable handlebar 100, the user may depress the positioning member 91 to release the sleeve 31 while rotating the sleeve 31 in a direction from the positioning member 91 to the guide member 81, at which point the depressed positioning member 91 is pressed under the sleeve 31, continuing to rotate the sleeve 31 until the end of the slotted opening 61 that was previously abutting the positioning member 91 abuts the guide member 81, at which point the guide member 81 serves as a rotational stop for the sleeve 31, at which point the cut-outs 71 are oriented downward.

The downward orientation of the cutout 71 allows the user to rotate the handle portion 51 downwardly until the side walls of the recess 511A of the handle head 511 abut the side walls of the projection 21A of the stop member 21, at which point continued forced downward rotation of the handle portion 51 will force the projection 21A of the stop member 21 to slide out of the recess 511A of the handle head 511, and the projection 21A will engage the peripheral wall of the handle head 511, in which position the handle portion 51 cannot swing freely, that is to say a firm collapsed state of the foldable handle 100 is achieved, as shown in fig. 6, 7, 9.

When it is desired to unfold the foldable handlebar 100, the user may first force the handle portion 51 upward, forcing the protrusion 21A of the stop member 21 to slide into the recess 511A of the handle head 511, continuing to rotate the handle portion 51 upward until the handle portion 51, i.e., the handle head 511, returns to being coaxial with the cross tube 2, as shown in fig. 5, 8. At this time, the sleeve 31 is rotated in the direction from the guide member 81 to the positioning member 91 until the slit opening 61 is rotationally moved above the positioning member 91, at which time the pressed positioning member 91 is released to bounce and abut against one end of the slit opening 61, so that the sleeve 31 is fixed again. At which time the cutout 71 returns to the forward orientation (or rearward orientation). Thus, the foldable handlebar 100 returns to the initial unfolded state, where the user can use the foldable handlebar 100 normally for skating.

With the above described invention an improved foldable handle with an unfolded and folded state is achieved that is simple in construction and reliable and stable.

The technical solutions of the present invention have been described in detail above with reference to the embodiments of the present invention and the accompanying drawings, so that those skilled in the art can better understand the technical solutions of the present invention. It is to be understood that the embodiments shown and described herein are exemplary only and not limiting. On the basis of which one skilled in the art can make any feasible modifications and variations, all of which fall within the scope of the invention.
