The present disclosure relates generally to rotational handle assemblies and more specifically to rotational handle assembly for strollers or the like.
Strollers or baby carriages are hand-pushed vehicles used for transporting babies and smaller children. Many variations of such strollers exist. An example is a jogging stroller that allows the user to jog while pushing the stroller. The multiple wheels at the base of the jogging stroller carriage allows for mobility of the user during jogging.
Generally, jogging strollers (and other stroller types) have fixed horizontal handles that provide a gripping surface for the user to hold onto while manipulating the stroller. In many instances, operation of the stroller can be cumbersome since the user's arm must typically remain immobile in a substantially horizontal position to manipulate the stroller, resulting in stress on the arms and wrists of the user.
It is within the aforementioned context that a need for the present disclosure has arisen, and the present disclosure meets this need.
Various aspects of a rotational handle assembly for strollers can be found in examples of the present disclosure.
In one aspect, the rotational handle assembly is pivotally attached to the stroller handle bar to facilitate pushing, pulling, steering, and general manipulation of the stroller. In one example, the rotational assembly includes a pair of handles that pivotally attach to the horizontal handle bar of the stroller. This pivotal articulation relative promotes natural swaying of the arms thus reducing stress on the wrists and arms of the user while operating the stroller.
In another aspect, the rotational handle assembly may axially rotate forwardly and rearwardly relative to a vertical plane of the horizontal handle bar of the stroller. Further, such axial rotation in the forward direction may continue until a first stop position is reached; after which the rotation is in a reverse direction until a second stop position is reached. The user or stroller operator may control the direction and extent of the rotation, through movement of the wrists and arms.
In one example, the pair of handles include a mount end, a body section, and a grip end. In some examples, the grip end has a C-shaped configuration that provides a natural fit for the hand. The mount end of the handles is configured for pivotally mounting onto the stroller handle bar. In some examples, the mount end is pivotally clamped to the horizontal handle bar.
The assembly is also unique in that each one of the pair of handles may partially rotate in two directions about the horizontal handle bar of the stroller. However, in alternative examples, the pair of handles is restricted to partially rotate in two directions about the horizontal handle bar, while below the horizontal plane. This provides a lower grip angle for user, if desired.
In addition, the pair of handles partially rotate in an upward and downward direction about the horizontal plane of the horizontal handle bar. In yet another example, the pair of handles partially rotate about the horizontal handle bar in a forward and backward direction relative to a vertically disposed plane of the horizontal handle bar.
In some examples, the body section of each of the pair of handles may have one of the following shapes: a linear shape, a bowed shape, a tortuous shape, and a U-shape. In addition, the mount end of the handle members is perpendicular to the body section of the handle members.
A further understanding of the nature and advantages of the present disclosure herein may be realized by reference to the remaining portions of the specification and the attached drawings. Further features and advantages of the present disclosure, as well as the structure and operation of various examples of the present disclosure, are described in detail below with respect to the accompanying drawings. In the drawings, the same reference numbers indicate identical or functionally similar elements.
Reference will now be made in detail to the examples of the disclosure, examples of which are illustrated in the accompanying drawings. While the disclosure will be described in conjunction with the preferred examples, it will be understood that they are not intended to limit the disclosure to these examples. On the contrary, the disclosure is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the disclosure as defined by the appended claims. Furthermore, in the following detailed description of the present disclosure, numerous specific details are set forth to provide a thorough understanding of the present disclosure. However, it will be obvious to one of ordinary skill in the art that the present disclosure may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail as to not unnecessarily obscure aspects of the present disclosure.
In
[24] Rotational assembly 100 includes a pair of connecting handles 106a, 106b. User 126 can hold connecting handles 106a, 106b while pushing, pulling, and steering stroller 104. The pivotal articulation of rotational assembly 100 relative to the horizontal stroller handle bar 102 works to reduce stress on the wrists and arms of user 126 while operating stroller 104.
For example, assume that user 126, a typical jogger, is jogging without a stroller. Naturally, user 126's arms would sway in a forward and backward direction. Rotational assembly 100 of the present disclosure promotes this natural forward and backward sway of the arms. As shown in
In this manner, unlike conventional systems where the user's arm must remain fixed and stationary on a stroller handle bar, the present disclosure uses the articulating and rotational assembly 100 to replicate the user's natural motion when a stroller is pushed. The present disclosure significantly reduces and/or prevents the stress and fatigue experienced by users' arms and wrist with conventional stroller activities.
This rotatable adjustability is possible because rotational assembly 100 can axially rotate forwardly and rearwardly relative to stroller handle bar 102. In one non-limiting example, this axial rotation can be up to 45° in both directions. In other examples, greater or less degrees of freedom for connecting handles 106a, 106b may be possible.
Further, rotational assembly 100 axially rotates in such forward direction 122 until a first stop position 122A is reached; and then rotates in a backward direction 120 until a second stop position 120A is reached. First stop position 122A may be positioned at a 45 degree angle relative to vertical plane 308 (
In another example, in addition to or in lieu of axial rotation in forward direction 122 and backward direction 120, axial rotation may be in an upward direction 116 and downward direction 118. Where movement is in upward direction 116 and downward direction 118, such movement is with respect to the horizontal plane 117 (or horizontal plane 306 of
In
Referring now to connecting handles 106a, 106b, the axial rotation in upward and downward directions 116, 118 about horizontal plane 306 (
As
Turning now to
Connecting handles 106a, 106b are defined by a mount end 108a, 108b, a C-shaped body section 110a, 110b, and a grip end 112a, 112b, respectively. Grip end 112a provides a surface for gripping connecting handle 106a. In some examples, the C-shaped configuration of grip end 112a can provide a natural fit for the hand of user 126. Grip end 112a may have a foam sleeve for additional grip comfort when the stroller is operated.
Body section 110a is a rigid, C-shaped configuration (in one implementation) that extends between the grip end 112a and mount end 108 of connecting handle 106a. In the C-shaped configuration, body section 110a forms a convex shape that protrudes toward user 126 for proximity to the hands of user 126.
However, as shown in
Mount end 108a of connecting handle 106a is configured for pivotally mounting to stroller handle bar 102 of stroller 104. In one non-limiting example, mount end 108a is oriented substantially perpendicularly to its adjoining body section 110a. This perpendicular orientation provides a parallel mounting position with stroller handle bar 102.
In
Further, clamps 614a, 614b are rotatable about stroller handle bar 102, such that connecting handles 106a, 106b at least partially rotate in two directions about stroller handle bar 102. A fastener 304 may secure clamp 614a, 614b to stroller handle bar 102, or to connecting handles 106a, 106b, or both. The fastener 304 may include, without limitation, a screw, a bolt, a lock, a pin, a magnet, and a tether.
Clamps 614a, 614b may include a resilient metal strap that wraps around mount end 108a, 108b of connecting handles 106a, 106b and stroller handle bar 102. In yet other examples, clamps 614a, 614b may include a rotational gear mechanism that fixedly attaches to stroller handle bar 102. One skilled in the art will realize that any comparable fastener or clamping mechanisms may be utilized.
Referring now to
In one non-limiting example, locking mechanism 302 may include an incremental mechanical device that allows connecting handles 106a, 106b to axially rotate in a controlled, incremental motion about stroller handle bar 102. Locking mechanism 302 can also be configured to enable connecting handles 106a, 106b to rotate freely in two directions about stroller handle bar 102.
Referring to
For example, as user 126 pulls connecting handles 106a, 106b in downward direction 118, and toward horizontal plane 306, springs 300a, 300b are extended and the tension load is increased until connecting handles 106a, 106b are pulled back above the horizontal plane 306. However, as discussed above, and as shown in
While the above is a complete description of exemplary specific examples of the disclosure, additional examples are also possible. Thus, the above description should not be taken as limiting the scope of the disclosure, which is defined by the appended claims along with their full scope of equivalents.
