Stationary jumping and trick bike

A stationary jumping and trick bike is disclosed. An example device includes a frame assembly having a handlebar on a forward portion of the frame assembly and a seat on the frame assembly. A leg member including a leaf spring is connected to the frame assembly by a bracket having a plurality of ports selectable for pivotably attaching the leg member to the frame assembly to adjust pitch and/or angle of attachment of the leg member. A plurality of tensioners are connected between the leg member and the frame assembly. A foot rest is provided on the frame assembly. A standing and/or seated user holding the handlebar on the frame assembly can practice jumps and tricks by lifting and landing a lower portion of the leg member on a solid surface.

BACKGROUND

Training devices, such as stationary bikes, are available so that the user does not have to go to a dedicated training facility or park when lack of time or distance is the issue. Some of these devices for jumping and tricks, require the rider to lay on his or her back and perform certain maneuvers and tricks from that position. However, there is a risk of injury. There are also other devices which involve using a bike or partial bike on a trampoline. However, this requires quite a bit of space to setup and use (typically outdoors), and again there is a risk of injury.

DETAILED DESCRIPTION

A stationary jumping and trick bike is disclosed which enables practice and training in a confined space, with less risk of injury than other techniques and/or devices (e.g., jumps and ramps). The “bike” disclosed herein is a “bicycle-like” apparatus which may introduce users to a new recreational activity/sport. It may also be implemented as an alternative tool for all types of bicycle enthusiasts/athletes to practice tricks/maneuvers. It can be enjoyed by anyone who is interested in a new, exciting, and fun activity/sport.

An example of the stationary jumping and trick bike is a stationary apparatus which includes a leaf spring (or other mechanical or non-mechanical spring such as air spring technology) that takes the place of the back wheel of a traditional bike. There is also no front wheel or fork. The example stationary jumping and trick bike also includes a base in which pedals can be installed into pedal ports to the riders preference. Other examples include pegs and pedals (without crank arms which come straight out of the bottom bracket), or crank arms with pedals and the option to either lock crank arms in position or add tension to keep them from moving freely. Riders can hop and jump from a stationary position while performing certain maneuvers and tricks that are commonly executed on BMX or MTB bicycles.

In an example, the stationary jumping and trick bike includes a frame assembly having a handlebar on a forward portion of the frame assembly and a seat on the frame assembly. A leg member (e.g., having a leaf spring) is connected to the frame assembly by a bracket having a plurality of ports. The ports are selectable for pivotably attaching the leg member to the frame assembly to adjust pitch and/or angle of attachment of the leg member. A plurality of tensioners are connected between the leg member and the frame assembly. If the user is comfortable with the tension of the leaf spring alone, the device can be provided without any tensioners or springs. A foot rest (e.g., pedal(s) or peg(s)) is provided on the frame assembly.

A standing and/or seated user holding the handlebar on the frame assembly can practice jumps and tricks by lifting and landing a lower portion of the leg member on a solid surface. However, it is noted that it may be difficult for a user to perform while seated. Just like many bicycle sports, the seat is more of a means to control the bike by the user's knees. Seats also assist in performing certain bicycle tricks and maneuvers while not in a seated position.

Before continuing, it is noted that as used herein, the terms “includes” and “including” mean, but is not limited to, “includes” or “including” and “includes at least” or “including at least.” The term “based on” means “based on” and “based at least in part on.”

It is also noted that the examples described herein are provided for purposes of illustration, and are not intended to be limiting. Other devices and/or device configurations may be utilized to carry out the operations described herein. The operations shown and described herein are provided to illustrate example implementations. It is noted that the operations are not limited to the ordering shown. Still other operations may also be implemented.

FIG. 1is a rear perspective view of an example stationary jumping and trick bike10.FIG. 2is a close-up view showing example pedals12and tensioners14of the stationary jumping and trick bike10shown inFIG. 1.FIG. 3is a front perspective view of the example stationary jumping and trick bike10shown inFIG. 1.

The example stationary jumping and trick bike10includes a frame assembly16. The frame assembly16includes a first tube member or seat post18supporting a seat20. The seat may be height adjustable (e.g., by loosening fastener21and raising/lowering a tube19(see, e.g.,FIGS. 5 and 6) attached to the seat20by sliding it within the seat post18.

A second tube member22a-bconnects to the handlebar24.FIG. 4is a close-up view showing an example adjustable handlebar post member22a-bof the stationary jumping and trick bike shown inFIG. 1. The second tube member includes a base tube22aand an extension tube22bslidably engaging therein to extend and retract the handlebar second tube member and hence the handlebar24, e.g., for distance of height adjustment. In an example, tube22bis referred to as a “boom bar” and provides reach adjustment (e.g., the user's arm reach). The boom bar22battaches to the head tube, the stem attaches to the pin that goes through the head tube and the handlebars mount to the stem. Different size “head tube pins” allow for the use of either BMX or MTB handlebars. The tubes22aand22bcan be secured at the desired position, e.g., by fastener23.

A third tube member or support post26provides support between the first tube member18and the second tube member22a-b.

The example stationary jumping and trick bike10also includes a foot rest on the frame assembly16. In an example, the foot rest includes pedals12. In another example, the foot rest includes posts12′ (see, e.g.,FIGS. 5-7).

The example stationary jumping and trick bike10also includes a leg member28pivotably attached to a rearward portion the frame assembly16, e.g., at the intersection of the first tube member18and the second tube member22a-b. In an example, the leg member28may include a leaf spring (e.g., a multi-layered spring). However, other mechanisms may also be provided, such as but not limited to a single layered spring a carbon fiber or other semi-flexible material, a hydraulic spring, an air spring. In an example, the leg member28has a semi-circular or crescent shape. However, other shapes are also contemplated as being suitable.

A standing and/or seated user holding the handlebar24on the frame assembly16can practice jumps and tricks by lifting and landing a lower portion of the leg member28on a solid surface (e.g., the floor, wall, or other suitable surface). A dampener30may be provided on the lower portion of the leg member28. The dampener30may be a rubber foot to reduce or altogether prevent damage to the floor or other surface on which the stationary jumping and trick bike10is being used.

In an example, the leg member28is pivotally attached at two spaced apart positions on the frame assembly16. For example, the leg member28may be pivotally attached at an intersection of the first tube member18and the second tube member22a-b, as seen in detail inFIG. 2. A connecting member or shaft32may pivotally attach the leg member28to the intersection of the first tube member18and the second tube member22a-b. In an example, the leg member28is pivotally attached to an upper position34on the first tube member below the seat, e.g., at pivot36.

In an example, at least one tensioner14is connected between the leg member18and the frame assembly16, e.g., at bracket15attached to the leg member18. InFIG. 1, three tensioners are shown. In the example shown inFIG. 5, 2tensioners are provided. Other examples including more or less tensioners may also be provided. The tensioner14is selectable by weight rating to increase and decrease stiffness of the leg member based on user size.

In an example, the tensioner is a coil spring. In another example, the tensioner may be a tension band. Coil springs, tension bands or mechanical coil springs can be added to increase stiffness to the leaf spring28and also help with recoil (or POP). Coil springs or tension bands may attach/connect at the middle area of the leaf spring and then attach/connect around the area of the bottom bracket. Coil Springs and tension bands may be weight rated so that the user can select the right amount of resistance for their body weight. Multiple coil springs and tension bands can be added or removed to adjust stiffness and recoil.

The stationary jumping and trick bike10may also include a bracket40on the frame assembly16. The bracket40may include a plurality of leg member ports41aand41b(although any number of ports may be provided). The ports41aand41bare selectable for pivotably attaching the leg member28via leaf spring pivotal arm31to the frame assembly16. This allows the user to adjust pitch and/or angle of attachment of the leg member28by removing the pin or shaft32and moving the leaf spring pivotal arm31from one port (e.g., port41a) to another port (e.g., port41b) and reinserting the pin32.

The bracket40may also include a plurality of ports42a-c,43a-c, and44a-c(although any number of ports may be provided). The ports42a-care selectable for attaching the tensioner(s)14to the frame assembly16. This allows the user to adjust tension by moving the tensioner(s)14from one port (e.g., port42a) to another port (e.g., port42bor42c).

FIG. 5is a front perspective view of another example stationary jumping and trick bike10′.FIG. 6is a rear perspective view of the example stationary jumping and trick bike shown inFIG. 5.FIG. 7is a close-up view showing example foot posts and tensioners of the stationary jumping and trick bike shown inFIG. 5. It is noted that like components are referred to by the same reference numbers and may not be described again with specific reference to these figures. The prime (′) designation indicates variations of the components already described above of the same reference number.

Again, the example stationary jumping and trick bike10′ includes a frame assembly16with handlebar24and optional posts12′. A leg28is pivotably attached to the frame assembly16. During use, a standing and/or seated user holding the handlebar24on the frame assembly can practice jumps and tricks by landing a lower portion of the spring mechanism on a solid surface. It is noted that the handlebar24is shown adjusted by extension member25for height inFIGS. 5 and 6.

In an example, the leg28includes a leaf spring. The leaf spring may be pivotally attached one or more positions on the frame assembly16. In the figures, the leaf spring is shown as it may be pivotally attached to a lower position on the frame assembly16beneath a seat post18. The leaf spring is also shown as it may be pivotally attached to an upper position on the seat post18of the frame assembly16.

Coil springs, tension bands or mechanical coil springs may be provided to increase stiffness to the leaf spring and also help with recoil (POP). Coil springs or tension bands attach/connect at the middle area of the leaf spring and then attach/connect around the area of the bottom bracket. Coil springs and tension bands may be weight rated so the user can select the right amount of resistance for their body weight. Also multiple coil springs and tension bands can be added or removed to adjust stiffness and recoil.

Adjustment bracket(s)40with multiple ports may be provided to allow the user to adjust the pitch/angle of the leaf spring by moving the leaf spring pivotal arm from one port to another, as already described above. This bracket may be located below the bottom bracket of the frame assembly16. The stationary jumping and trick bike10′ may also include ports41a′-41d′ are selectable for pivotably attaching the leg member28via leaf spring pivotal arm31′ to the frame assembly16. This allows the user to adjust pitch and/or angle of attachment of the leg member28by removing the pin or shaft32and moving the leaf spring pivotal arm31′ from one port (e.g., port41a) to another port (e.g., port41b) and reinserting the pin32. In this example, the leaf spring pivotal arm31′ is further adjustable, e.g., by extending or retracting the arms31a′ and31b′ via threads31c′.

In an example, the stationary jumping and trick bike10′ includes a dampener30on the lower portion of the leaf spring. The dampener30may help to reduce or altogether prevent damage to the floor by the spring mechanism. For example, the dampener may be plastic rubber or other softer material than the metal leg member28.

In an example, the stationary jumping and trick bike10′ includes one or more port or other mounting location to receive a pedal or other foot rest or “peg(s)” on the frame assembly. For example, a pedal or other foot rest may be attached on each of two opposite sides of the frame assembly. The ports or other mounting locations provide options to receive the pedal(s) or other foot rest(s) at different positions on the frame assembly, e.g., for different size users, different tricks, or other user preferences.

In an example, the stationary jumping and trick bike (10or10′) may be provided in a 20 inch BMX geometry and/or a 26/27.5 MTB or “dirt jumper” geometry. Either BMX or MTB handlebars and pedals may be used with the device, and may be adjustable and MTB/BMX parts compatible to the users liking. In another example, the apparatus is not built with a specific BMX or MTB geometry. The user can adjust the frame tube, seat post, leaf spring pitch/angle. An adjustable/adaptable steer tube which goes through the head tube may allow user to use MTB handlebars. Also a second option frame tube which adds a rise to the head tube may be an alternative to using MTB handlebars.

The stationary jumping and trick bike (10or10′) may also include 19 mm, 22 mm, 68 mm and 73 mm bottom bracket sizes and/or a stationary standing platform with optional threaded ports for bike pedals. However, it is noted that other device configurations and sizes may also be included and is not limited to any particular configuration or size.

In an example, the stationary jumping and trick bike (10or10′) may be fully adjustable, with the ability to collapse or extend nearly every component for the user's preferences.
