Abstract

An additional handlebar for a wheeled vehicle, e.g. a child's bicycle, comprises a telescopic stem 4, a handlebar portion 2 which is movably and pivotally secured to one end of the stem, and attachment means 3, e.g. belt and buckle, that are secured to the other end of the stem and which enable the additional handlebar to be detachably mounted to the existing handlebars of the vehicle. The arrangement allows a child's bicycle to be easily pushed by an adult.

Description

1 2412098 Removable Height Adjuster This invention relates, in part, to

the field of devices aimed at minimizing the strain incurred by persons in the operation of certain vehicles including bicycles. For example, an average-sized adult wheeling a young child's bicycle usually sustains some bodily sprain and discomfort from the awkward body positioning, such as stooping, necessary to perform the task.

The present invention seeks to alleviate that predicament.

The Removable Height Adjuster achieves this goal by serving as a bridge between the vehicle and the person seeking to steer and control it. This invention attaches unto the parts of the vehicle by which it is steered while at once extending to fit the height and comfort requirements of vehicle operator.

Applicant is not aware of significant prior art that address the problem aforestated nor remedy same as applicant's present invention does.

The schematic drawings accompanying this description are: Fig. 1 which is a side view of a preferred embodiment of the Removable Height Adjuster while extended Fig. 2 which is a side view of the Fig. 1 embodiment in a folded position Fig. 3 which is a perspective view of another preferred embodiment of the Removable Height Adjuster Fig. 4 which is a side view of a length securing means for a telescopic stem.

Figure 1 discloses a preferred embodiment of the Removable Height Adjuster as consisting of a telescopic stem 4, securable at any point on its range of extension by the length securing means 8 (exemplified in figure 4), and to which is attached at one end two handlebars 2. Said handlebars 2 are attached to the telescopic stem 4 by means of adjustable elbows 5 that allow the handle bars 2 to move freely and be securable in any part of its range of motion/ for example, perpendicular to the stem 4 (figure 1) or folded to the sides of the telescopic stem 4 (figure 2). At the other end of the telescopic stem 4 are attached, also by means of adjustable elbows 5, clasping arms 6. These operate and are similar to the handlebars 2 but have the additional feature of clasping means 3 along its length, preferably at the outer ends. These clasping means may be belt and buckle combinations, Velcro (I) straps (both not shown) or other suitable means and they firmly and securely attach the Removable Height Adjuster to the vehicle desired to be controlled.

Figure 2 discloses the Removable Height Adjuster of figure 1 while in a folded position.

Figure 3 discloses an alternate embodiment of the Removable Height Adjuster. It is similar in all respects to that in Figure 1 except for its additional telescopic support arm 7, by which the Removable Height Adjuster is further secured to the vehicle being steered and controlled. Said telescopic control arm 7, which is securable at any point on its range of extension by the length securing means 8 (exemplified in figure 4), attaches to telescopic stem 4 by means of an adjustable elbow 5 and terminates at its other end in clasping means 3.

Figure 4 discloses a well-known example of a telescopic stem securing means.

It consists of a body with a screw thread bore 9 attached to the outer section of the telescopic stem 12 and through which a screw 10 is driven to hold the inner section of the telescopic stem 11 at a desired position and place of extension.

Upon attaching the clasping arms to the vehicle, the person operating the device extends the telescopic stem 4 to a desired and comfortable height while also adjusting and securing the handlebars 2 at a preferred angle. With such settings the person operating the device can then comfortably steer and control the vehicle without strain - strain such as stooping or crouching continuously.

Notwithstanding the illustrations and descriptions aforestated however, it is intended that the scope of this invention be no way limited. The preferred embodiments have been set forth as illustration only and any alteration, modification, combination or such like, within the spirit of the invention, is desired to be protected.

Legend 2 = handlebars 3 = clasping means 4 = telescopic stem

= adjustable elbow

6 = clasping bars 7 = telescopic support arm 8 = telescopic stem length securing means 9 = body with screw thread bore = screw 11 = inner tubular stem 12 = outer tubular stem

Claims

Removable Height Adjuster 1. A removable height adjuster comprising a. at least one telescopic stem, securable at any point on its range of extension b. at least one handlebar attached along the length of said telescopic stem, preferably at one end, said handlebar being so attached by means of an adjustable elbow that allows the handlebar to move freely and be securable at any point in its range of motion c. at least one clasping arm with clasping means attached along the length of said telescopic stem, preferably at the end opposite that at which said handlebars are attached, said clasping arm being so attached by means of an adjustable elbow that allow the clasping arm to move freely and be securable at any point in it's range of motion whereby a vehicle to which said removable height adjuster is attached using said clasping means is comfortably steered and controlled by different sized operators.
