Bicycle and Tricycle Safety Distance Buffer Apparatus

Abstract

The embodiments show an efficient, flexible, durable, lightweight and portable (12) electromechanical apparatus (12) that a cyclist can easily and safely operate. The design allows for the remote positioning of a visible elongated object, (12) safety sleeve/arm (12), from a secured vertical stowed position, to a secured horizontal active position without stopping during the ride. The elongated, aerodynamically shaped (12) safety sleeve (12) will have (12) LED strip lights (12) along the trailing edge, along with a (12) wing tip light (12) at the end of the member. Also included are reflective materials at both ends and on the leading edge of the (12) safety sleeve (12). The purpose of a (12) safety sleeve/arm (12) in the active horizontal position is to provide oncoming motorists with a dimensional frame of reference to clear the pedal vehicle when passing. Because of the size and shape of the lighted safety member, a motorist will receive the early detection needed, allowing them time to maneuver their vehicle around the cyclist. Thus, providing adequate clearance between the cyclist and motorist when passing, which will help them to comply with the 3 foot rule enacted in 33 states in the USA.

The adjustable mechanical stop 508 is strategically located and attached to base plate 502. The “European Design” (horizontal right-side active position) is a mirror image of the North American version. The ease of conversion is simple. Whereby, base plate 502 is flipped over and original components reattached. All components supplied are the same for both North American and European applications.

[0087] FIG. 12—shows assembly plan view for the electromechanical series 500 with 502 base plate.

[0088] FIG. 15—shows assembly plan view for the electromechanical universal series 500 with 503 base plate.

[0089] NOTE: Although the models presented in this application have different OD configurations, all models share the following common design parameters.

[0090] (a) All base plates 503, 502, 402 and 302 have the same identical index pattern 19 mm (0.75″), radius of travel off spar arm pivot bolt 610a centerline. This radial index pattern locates spar arm 602a-b into the horizontal (active) or vertical (stowed) positions.

[0091] (b) Spar Arm 602a-b is interchangeable between all models.

[0092] (c) The adjustable vertical and horizontal mechanical stop 508 with 508a-c hardware is interchangeable.

[0093] (d) Component related assembly and fastening of spar arm 602a-b to base plates are identical.

[0094] (e) Mount hole locations for installing the assemblies onto a traditional seat post beam mount, or bicycle rear luggage carrier rack use the same dimensional pattern. (Series 300 is the only exception)

[0095] (f) Series 500 models, with base plates (503 & 502) can perform as a hand operated, or electromechanically actuated system, as shown in previous embodiments.

[0096] FIG. 16—displays a perspective view of series 500 manual model that uses universal base plate 503. Users that prefer starting with a manual system to determine the effectiveness of the device, can mount base plate 503 at any of the locations previously discussed. To upgrade from the manual HO device to the electromechanical actuated system, the remaining components required comprise the following . . . (1) Actuator riser mount 504, (1) electric linear actuator 506, (1) electrical wiring harness FIG. 45, and associated hardware, as shown in embodiment FIG. 19

[0097] FIG. 17—shows a more detailed plan view of the universal series 500 assembly using base plate 503, which has a slight OD variation compared to base plate 502. This is because base plate 503 is capable of replacing all previous mount configurations needed to install devices on a bicycle, or a three wheeled trike vehicle. Although base plate 503 has a slightly different outline, the dimensions of the internal indexing mechanism and components used for this apparatus is identical to all other models previously shown and described.

[0098] Spar arm 602a-b attaches to base plate 503 in such a manner to be secure, yet can rotate at the center bolt pivotal connection. Additional assembly includes attaching actuator support riser 504 to base plate 503, then securing actuator 506 to support riser 504 at the pivotal fixed end of actuator body. Followed by securing the clevis end of actuator push rod to spar arm 602a. Because of the slight radius of axis that develops during the 50 mm (2″) stroke of actuator 506, a slight lateral back-and-forth travel of the actuator body occurs during operation. Therefore, actuator 506 is contained by placing two (2) keeper bridge pieces 510 over the top of shaft housing, along with one (1) support spacer 516 under the shaft housing. These are used to restrict any upward or downward movement of the actuator body and shaft housing during operation, yet allows the actuator the freedom to move laterally.

[0099] FIG. 18—is a perspective view of series 500/503 universal base plate assembly, which displays the spar arm 602a-b with the dual spring breakaway feature. Note, the X-X & Y-Y bolt pattern shown on base plates 503, 502, and 402 are identical and designed to match a common bolt pattern used by bike rack manufactures for rear reflector mounts. Typically one (1) or two (2) fasteners 526 will secure the bottom of series 400 or 500 base plates to a reflector bracket. These reflector brackets are commonly supplied with a seat post or rear bicycle luggage rack. This embodiment also shows the various fasteners and the locations that offer the user alternate possibilities to install series 500/503 assembly. Fasteners 306 and 310 are used to mount base plate 503 assembly to a horizontal tubular frame member. Whereas universal angle brackets 804 and 806, (ref. FIG. 23B), are attached using fasteners, 526a-c and 528a-c.

[0100] Universal angle brackets 804 and 806 allow mounting of series 400 and series 500 assemblies to a typical bicycle seat post beam rack, or rear luggage carrier rack (ref. FIG. 35 to 40).

[0101] FIG. 19—this embodiment is an exploded view of series 500/503 assembly parts and components. The fabricated components for base plate 503, actuator support riser 504, spar arm 602a-b and mechanical stop 508 assembly are all made of HDPE (high density polyethylene) lightweight, very durable material, with approximate dimensions of 9 mm (⅜″) & 19 mm (¾″) thick. This HDPE material is best suited for harsh sun and tough marine applications, for it will not rot, swell, splinter or delaminate when exposed to humidity or water. Although this special HDPE material appears best suited for all fabricated embodiments presented, other plastic, composite or metal materials are satisfactory.

[0102] Base plate 503 will have seven (7) non-ferrous threaded metal inserts 522 installed as shown. To reinforce the four (4) detent points (D1, D2, D3 & D4), on a 19 mm (0.75″) radius, four (4) rivet style inserts 524 are installed. Once assembled, these detent locations in base plate 503 will dimensionally mate with the threaded ball plungers 606 installed in the spar arm 602a on about a 19 mm (0.75″) radius off centerline of pivot bolt 610a.

[0103] Support riser 504 attaches to base plate 503 using fasteners 514, followed with the installation of actuator 506 on support riser 504, using fastener 512 with spacer 512a at the pivotal end of actuator. Two (2) keeper bridge pieces 510 are secured over the top of shaft housing, along with one (1) support spacer 516 under the shaft housing. These keeper pieces and spacer are lightly snug fit in place using four (4) fasteners 518. Then fastener 520 with spacer 512b secures the clevis end of moveable push rod shaft to the spar arm 602a.

[0104] Spar arm 602a and 602b are two fabricated HDPE pieces sized and shaped to snuggly fit into the longitudinal through hole of the airfoil safety sleeve arm 702. At approximately the center-point of spar arm, there is a pivoting joint with two (2) springs 604 under tension and secured with two (2) fasteners 608a, 608b. One (1) threaded insert 522 is installed at pivotal end of spar arm 602a to receive actuator 506 clevis push rod shaft end, which is secured with fastener 520 and spacer 512b. Ball plungers 606 are installed to a predetermined depth into the drilled and tapped holes in spar arm 602a. This procedure ensures a positive seating of the spar arm will occur when mated with the detent locations on base plate 503. The design allows the user to make finite adjustments to balance the force of this connection between spar arm 602 and base plate 503. This is accomplished by tightening or loosening the pivotal bolt hardware 610a-c and balance this action against the depth of ball plungers 606, related to the power curve of actuator 506.

[0105] Last step is to secure mechanical stop 508, with associated hardware 508a-c, to base plate 503. Once mechanical stop hardware with jack bolts 508c are installed, final vertical and horizontal alignment of spar arm 602/safety sleeve assembly 702 can be completed. As previously stated, the X-X & Y-Y bolt pattern shown at the bottom right side of base plate is typical on models 503, 502, and 402. They are identical and designed to match the common bolt pattern that bike rack manufactures use for rear reflector mounts.

[0106] FIG. 20—shows a more detailed plan view of series 500/502 assembly. Although base plate 502 has a distinct outline, the dimensions of the internal indexing mechanisms and components used for this apparatus is identical to all other models previously shown and described.

[0107] Spar arm 602a-b attaches to base plate 502 in such a manner to be secure, yet can rotate at the center bolt pivotal connection. Additional assembly includes attaching actuator support riser 504 to base plate 502. Then secure actuator 506 to the actuator support riser 504 at the fixed base, pivotal body end of actuator. Followed by securing the actuator push rod clevis end to spar arm 602a. Because of the slight radius of axis that develops during the 50 mm (2″) stroke of actuator 506, a slight lateral back-and-forth travel of the actuator body occurs during operation. Therefore, actuator 506 is contained by placing two (2) keeper bridge pieces 510 over the top of shaft housing, along with one (1) support spacer 516 under the shaft housing. These are used to restrict any upward or downward movement of the actuator body and shaft housing during operation, yet not impede lateral movement of actuator 506.

[0108] FIG. 21—is a perspective view of series 500/502 universal base plate assembly, which displays the spar arm 602a-b with the dual spring breakaway feature. Note, the X-X & Y-Y bolt pattern shown on base plates 503, 502, and 402 are identical and designed to match a common bolt pattern used by bike rack manufactures for rear reflector mounts. Typically one (1) or two (2) fasteners 526 will secure the bottom of series 400 or 500 base plates to a reflector bracket. These reflector brackets are commonly supplied with a seat post or rear bicycle luggage rack. This embodiment also shows the various fasteners and the locations that offer the user alternate possibilities to install series 500/502 assembly using universal angle brackets 804 and 806, (ref. FIG. 23B), which are attached using fasteners, 526a-c and 528a-c.

[0109] Universal angle brackets 804 and 806 allow mounting of series 400 and series 500 assemblies to a typical bicycle seat post beam rack, or rear luggage carrier rack (ref. FIG. 35 to 40).

[0110] FIG. 22—this embodiment is an exploded view of series 500/502 assembly parts and components. The fabricated components include base plate 502, support riser 504, spar arm 602a-b and mechanical stop 508 assembly are all made of an HDPE (high density polyethylene) lightweight, but very durable material. Although the HDPE material appears best suited for all the fabricated embodiments presented, other plastic, composite or metal materials are satisfactory.

[0111] Base plate 502 will have seven (7) non-ferrous threaded metal inserts 522 installed as shown. To reinforce the four (4) detent points (D1, D2, D3 & D4), on a 19 mm (0.75″) radius, four (4) rivet style inserts 524 are installed. Once assembled, these detent locations in base plate 502 will dimensionally align with ball plungers 606 as installed in the spar arm 602a on about a 19 mm (0.75″) radius off centerline of pivot bolt 610a. Support riser 504 bolts to base plate 502 using fasteners 514, followed with the installation of actuator 506 on support riser 504, using fastener 512 with spacer 512a at the pivotal end of actuator. Two (2) keeper bridge pieces 510 are secured over the top of shaft housing, along with one (1) support spacer 516 under the shaft housing. These keeper pieces and spacer are lightly snug fit in place using four (4) fasteners 518. Then fastener 520 with spacer 512b secures the clevis end of moveable push rod shaft to spar arm 602a.

[0112] Spar arm 602a and 602b are two fabricated HDPE pieces sized and shaped to snuggly fit into the longitudinal through-hole of safety sleeve 702. At approximately the center-point of spar arm, there is a pivoting joint with two (2) springs 604 under tension and secured with two (2) fasteners 608a, 608b. One (1) threaded insert 522 is installed at pivotal end of spar arm 602a to receive actuator 506 clevis end of push rod, which is secured with fastener 520 and spacer 512b. Ball plungers 606 are installed to a predetermined depth into the drilled and tapped holes in the spar arm 602a. This procedure ensures a positive seating of the spar arm will occur when mated with the detent locations on base plate 502. The design allows the user to make finite adjustments to balance the force of this connection between the spar arm 602 and base plate 502. This is accomplished by tightening or loosening the pivotal bolt hardware 610a-c and balance this action against the depth of ball plungers 606, related to the power curve of actuator 506. Last step is to secure mechanical stop 508, with associated hardware 508a-c, to base plate 502. Once mechanical stop jack bolts 508c components are installed, final vertical and horizontal alignment of spar arm 602/safety sleeve assembly 702 can be completed. As previously noted, the X-X & Y-Y bolt pattern shown at the bottom right side of base plate is typical on models 503, 502, and 402. They are identical and designed to match the common bolt pattern that bike rack manufactures use for rear reflector mounts.

[0113] FIG. 32A—shows a plan view and side elevation view of the interchangeable spar arm 602a and 602b, fabricated in two (2) pieces, sized and shaped to fit into the longitudinal through-hole of the airfoil safety sleeve arm 702. The spar arm is approximately 10 mm-19 mm (0.375″-0.75) thick×25 mm (1″) wide×610 mm-711 mm (24″-28″) long. At approximately the center-point of spar arm 602a-b, there is a pivoting joint with two (2) springs 604, both under tension and secured with two (2) fasteners 608a, 608b. One (1) threaded insert 522 is installed at the pivoting, bottom end of the spar arm 602a, allowing actuator 506 push rod clevis to connect with spar arm using fastener 520.

[0114] FIG. 32B displays two (2) ball plungers 606 installed to a predetermined depth into the drilled and tapped holes within spar arm 602a. This process will allow for positive seating of spar arm 602a when mated with detent locations in base plates 503, 502, 402 and 302.

[0115] FIG. 32C—shows a plan view of spar arm 602a-b, with breakaway joint concept using containment springs 604 under tension that act like ligaments to hold the two (2) support spar arm sections together. This breakaway arm design not only allows travel in two directions following the radial axis of the fabricated joint shown, but it also allows the upper arm to pivot laterally.

[0116] FIG. 32D—displays an approximation of the inherent resiliency of the HDPE material used to fabricate spar arm 602a-b, which offers an additional measure of stress relief from sudden impacts. Considering the materials used, coupled with the dual spring breakaway feature, spar arm 602a-b can withstand an impact from any direction and will thus help absorb and deflect the force of an impact away from the cyclist.

[0117] FIG. 33—represents the low density foam XLPE (cross-linked polyethylene) airfoil shaped safety sleeve 702, with an internal 25 mm (1″) diameter hole extending through the full length of the member. The overall length of safety sleeve 702 is approximately 610 mm-914 mm (24″-36″). Although the sleeve material selected is a lightweight XLPE material, other materials, shapes and sizes may be considered satisfactory. For increased visibility, reflective material 704 and 706 is wrapped around the top and bottom base ends of safety sleeve 702. Also, a reflective strip 708, approximately 50 mm (2″) wide×610 mm (24″) long is attached to the front (leading edge) of safety sleeve 702. These reflective tape additions further enhance nighttime visibility of the safety sleeve/arm to vehicles approaching the cyclist from the front. A set of 12V-24V low voltage LED ultra-bright strip lights 710 are installed full length on trailing edge. Also mounted on the very top end of sleeve 702 is a reflective material end cap 712, along with a single low voltage LED wing tip light 714 that will protrude into the lane, which further draws attention to the cyclist's safe zone of travel.

[0118] FIG. 34—is the perspective view of safety sleeve 702 with spar arm 602a-b sections sized and shaped to fit snuggly into the sleeve's ID longitudinal through through-hole. Safety sleeve 702 dimensions are, but not limited to, approximately 45 mm (1.50″) radius at the leading edge, a 19 mm (¾″) deep trailing edge, having a 114 mm (4.50″) profile width×762 mm (30″) to 914 mm (36″) overall length. The safety sleeve 702 is also removable, portable and interchangeable with all model series presented.

Operation: FIGS. 1, 2, 3, 6, 7, 9, 10, 12, 15, 16, 17, 18, 19, 20, 21, 22, 32, 33 & 34

[0119] The indexing system of all model series comprises up to four (4) fabricated component sections made of structurally sturdy material, which can be a high density polyethylene (HDPE), composite, or metal material. All base plate models have predetermined detent locations to receive the head (s) of the ball plunger locaters. A ball plunger is a spring-loaded ball tipped component, which places the ball under pressure from an internal compression spring within the housing of the ball plunger. These ball tipped locaters are installed in the pivotal end of spar arm. As the spar arm rotates to a vertical stowed, or horizontal active position, positive seating of the ball plungers into the base plate detents at each location is required for successful operation. This is accomplished by compressing the pivotal end of the support spar arm against base plate, using a fastener bolt with a locknut. Tightening or loosening of this fastener provides infinite control over the degree compressive strength that is needed to engage the ball plungers into the base plate. Too much pressure will create a binding action, whereas too little pressure causes the spar arm/sleeve to wobble. Therefore, the goal is to achieve a balance between properly engaging the ball locators to firmly seat the arm into the base plate, with just enough pressure to maintain stability, but not cause any binding between the two pieces. Once proper compression/tension adjustments are complete, the system can be actuated manually or electrically to move the spar arm into the vertical, or horizontal detent locations in base plate. Using the mechanical stop jack bolts, final vertical and horizontal alignment of the spar arm/safety sleeve can be achieved.

[0120] The semi-automatic electrically actuated mechanism is a unique design feature of series 500 models. This feature allows the cyclist to perform all spar arm/safety sleeve actions using a direct wired or wireless remote key fob and latching relay contacts to control the movements of the electric linear actuator. During a ride, the cyclist can move spar arm/safety sleeve with a push of an up/down button on the key fob. For ease of recognition, the key fob buttons have directional arrow symbols. Once the key fob is actuated, the spar arm/safety sleeve will automatically seek the selected location. When the actuator push rod reaches either the fully retracted or fully extended stroke, the actuator's internal limits will trigger the relay to disconnect the power supply. This all happens simultaneously as spar arm settles into the base plate detent (s) aligned with the selected position. A cyclist will find this a very convenient and a much safer way to actuate spar arm/safety sleeve while the pedal vehicle is in motion.

[0121] At present, it appears the Series 500 models are the most effective and efficient. However, the other hand operated systems discussed (series 300 and 400) are satisfactory.

[0122] The airfoil shaped safety sleeve is designed to slide over the support spar arm. Because the spar arm is slightly larger than the longitudinal through-hole diameter of the foam safety sleeve, it will fit snuggly and securely inside the sleeve. The spar arm is interchangeable between all base plate designs used for series 300, 400 or 500 models. The slim design of the spar arm also enhances flexibility because of the inherent resiliency of the high density HDPE polyethylene material. However, the spar arm dual spring breakaway feature also allows this safety arm to withstand a significant impact from any direction. Because of the inherent resiliency of the materials used, coupled with the breakaway spring design, makes this spar arm/safety sleeve a very rugged and robust device.

[0123] The XLPE low density foam selected for the safety sleeve is a very lightweight, flexible and non-abrasive material. Therefore, if the sleeve contacts an object, or an object strikes the foam sleeve, the object and/or the sleeve would exhibit limited to no damage. Because yellow is the first color the human eye recognizes, the brilliant yellow color was selected for the safety sleeve, but other colors and materials are also suitable.

[0124] To add another level of visibility, the ultra-brilliant LED strip lighting installed on the trailing edge of the airfoil sleeve, along with a wing tip LED light, creates a very visible elongated object seen from a considerable distance day or night. The LED strip lights and wing tip light include a separate control for light intensity and pulse mode. This provides the operator the ability to vary the frequency of light pulsations, thus improving the objects visibility to approaching motorists.

[0125] Installation of the safety distance device is simple. There are various mount concepts discussed and displayed herein for the mechanical indexing mechanisms, yet are not limited to the shapes and sizes shown. These mount configurations adapt to a vast majority of bike/trike frames and/or rear luggage carrier rack designs.

CONCLUSION, RAMIFICATIONS AND SCOPE

[0177] The reader will find that at least one embodiment of the safety distance buffer apparatus provides a more reliable, durable, lightweight and effective device. A device that a multitude of cyclists can use for most, if not all, two and three wheeled pedal vehicles. While my description contains many specificities, please do not construe these as limitations on the scope, but as an exemplification of embodiments thereof.

Advantages

[0178] (a) The overall design of the indexing mechanisms use a common dimensional pattern that are repeated throughout the multiple base plate iterations.

[0179] (b) We do not limit the use of HDPE material to fabricate the indexing systems, for other materials such as plastics, composites, or metal are satisfactory.

[0180] (c) Spar arm and hardware are of a common design to allow interchangeability between all base plate configurations.

[0181] (d) Should electric linear actuator become inoperable for any reason, series 500 mechanism's design allows the system to function manually. This is accomplished simply by disconnecting the fastener bolt used to secure the linear actuator push rod to spar arm.

[0182] (e) The user can opt to begin with a series 500 model with either base plate 502 or 503 and use this device as a manual system. Then, whenever the desire arises they can upgrade to the electromechanical device. This upgrade requires the user to order the remaining parts needed 504, 506, and applicable wiring harness FIG. 45 with key fob 902 to make this conversion.

[0183] (f) The design also allows for easy installation/mount interchangeability between base plate models.

[0184] (g) We do not limit the use of XLPE material for the fabrication of safety sleeve 702. Other similar materials, colors and shapes may prove satisfactory, provided they meet the flexibility and structural integrity requirement for the application.

[0185] (h) We do not limit the use and number of the ball plungers as described. We consider other similar or equivalent locater type components as satisfactory.

[0186] (i) The electromechanical design is not limited to using an electric linear actuator, for other similar or equivalent linear, or rotary electric, pneumatic, or hydraulic actuators would be satisfactory.

[0187] (j) Other equivalent or similar LED lights are acceptable, along with suitable controls capable of varying the brightness, pulse mode and pulse frequency are also satisfactory.
