Abstract

The use of clip pedals and appropriate footwear has proved itself for cyclists, however, said use is avoided by many due to an immanent risk of injury. All of the currently existing clip release systems can only be released by using a release technology by means of specific foot movement. This is particularly problematic in stress situations. A safe and quick release of bicycle pedal clips to avoid falls, and to provide sufficient comfort when using bicycle clip pedals without appropriate footwear has been lacking up to now. The invention relates to a practicable solution thereto that allows the realization of an efficient seconday release mechanism. The release of the foot pedal clip is hereby illustrated by means of a hand-operated cable pull, or electronically. The basic principle is the use of a pre-tensioned spring, which releases the retaining bolt on the clip pedal. The invention further relates to the use of a cover plate for situations in which the clip system is not being used with appropriate footwear. The solution according to the invention can contribute significantly to an increased attractiveness of clip pedal systems.

Description

BIKE PEDAL CLIP COVER AND TRIGGER ENCHANISM

Technical area

Bicycle technology, pedal technology

Underlying state of the art

Currently there are only triggered by foot movement Bicycle pedal clip systems, which with suitable footwear and more specifically, too training foot technique are connected.

Technical problem

The currently existing triggering systems can in each case only using a triggering technique by means of specific Foot movement to be solved. This is especially in stressful situations problematic. A safe and fast solution of bicycle pedal clips to Avoid falls, as well as sufficient comfort when using Fahrradclippedalen without matching footwear is missing so far.

Technical solution

Triggering the foot pedal clips by means of a hand-operated Cable or electrical or electronic triggering, as well as a Cover plate when not using the clip system.

Release versions:

Attaching a dedicated button or Release lever on the handlebar or at a suitable position. "Emergency release button / lever" in handlebar grip area Bowden / cable from the handlebar of the bike to the clip pedals.
Use and extension of existing brake cables and levers: when a full brake application is triggered via the brake cable (selectable or rear brake or together), the lever cable is simultaneously actuated. The realization takes place by means of Y-Bowden cable distributor or at electromagnetic triggering by means of control cable contact in the brake handles, which are individually adjustable.
Triggered by tilt sensor on the frame or Smartphone with frame mount and associated app via Bluetooth (4.0), ANT, ANT +, Zigbee, etc. - the signal is sent to the pedal release mechanisms forwarded. The calculation of the angle of inclination and the Time duration / speed as well as the evaluation of the tilt characteristic of the Fahrrads done by the app, which if necessary the appropriate Triggered by solenoid initiated. Multiple user profiles or Trigger sensitivities can be set in the app.
A combination of variant one and two or one, two and three can be realized.

In addition, a solution would be the Clip-pedal anchoring possible by means of a servomotor, which the Retaining bolt releases.

Is by one of the four variants mentioned the Solution of the clip initiated via cable on the handlebar, this happens in the first Step by a mechanical force by means of cable 90 degrees in relation on a rotating shaft (bottom bracket). An electromagnetic, hydraulic or pneumatic triggering would also be possible. The cable from the handlebar Coming terminates on an elastic on the outside of the shaft (e.g. Plastic) bearings in a rope groove. The recess for this bearing is in provided static outer part of the bottom bracket. By the resulting Surface pressure on the trigger surface will be the two endpoints (beveled) of the holding / release lever actuated. This will trigger the right and on the left side of the shaft ensured. The outboard (in relation to the rotational movement) end points of the holding / release lever are designed bolt-like and slightly above the level of the Wave out. This leads to the solution of the holding lever via deflection from the Sleeve / lever snap-in, which in turn is the preloaded springs (Spring) relaxed. The end points of the holding lever in the latching opening are beveled on both sides, fitting as a counterpart to the sleeve opening designed and hardened to prevent material abrasion. To the outer end points of the prestressed springs is one each Spring guide plate mounted, which defines the leadership of the spring on Spring travel within the spring sleeves is used. At the inside end point of the Prestressed springs, these are to a central spring / sleeve mounting disc appropriate. At the spring guide plate, the cables are mounted on Seileinhakösen for decoupling of the bottom bracket rotation movement Attached pedal clip. Due to the now released traction is the Clip retaining bolts on the pedals and thus the connection between pedals and Shoes solved. After a successful release, the mechanism is manually activated by the Users reactivated via reset tension spring and thus become to this Time unbiased springs again biased and by the Locking springs fixed in the sleeve / lever latching opening. The handle for the Operation of the return tension spring can be either permanently mounted or removable be. Details on the procedure are noted in the picture descriptions.

Description Pedal cover plates: Cover the Shoe clip holder on the pedal by means of a so-called "negative piece" to the To increase comfort when using footwear without clip inserts. The Pedal cover plates provide the user with a fixed in the clip wells, flat pedal surface incl. optional reflectors. The pedal cover set is with the common clip system compatible and is hooked to elastic Fixed ribbons. The pedal surface can be designed freely. at Not use the cover plates with elastic available Ribbons are attached to the frame.

Advantageous effects

Reduced risk of injury from rapid and easy solution of shoe-pedal connection.
Stress reduction in dangerous situations, since the Triggering does not have to be done exclusively with the fixed legs / feet.
Risk of falls by beginners due to lack of experience minimize with the triggering mechanism.
Comfortable use of pedal clip systems without suitable footwear (everyday shoes), mounting option for reflectors.

Description of the drawings

Drawing 1: Represents power transmission paths for a Pedalcliplösung on or in the bicycle frame. The release can by means of Cable or electromagnetically made. In the variant Trigger via (5) Lever cable from the handlebar to the bottom bracket (6) of the bicycle becomes the mechanism within the bottom bracket triggered by the (8) pedal cable and the Shoe / Clippedalverbindung solved. In the variant electromagnetic tripping this is done analogously by means of (7) electromagnet within the bottom bracket. Furthermore, the different tripping variants, as described in the chapter "Technical Solution ", visualized, that is affixing a dedicated Button or (1) release lever. Other variants are the triggering via Existing (2) brake lever and a (9) Y-Bowden cable distributor or the Using a (3) smartphone tilt sensor using an app or a dedicated (4) tilt sensor. The variant (3) smartphone tilt sensor with App or using a dedicated (4) tilt sensor, controls each of the (7) Electromagnet for solving the pedal / shoe connection inside the bottom bracket at. Instead of the (5) lever cable can also be a power cable for transmission the activation signal to the (7) electromagnet can be used.

Drawing 2A and 2B: The (5) lever cable from Arriving handlebars terminating on a shaft outboard (9) elastic (e.g., plastic) bearing in a (10) rope groove. The (5) Lever cable is through the (14) shaft hole for cable entry to Introduced inner shaft. Due to the resulting surface pressure on the (11) Trigger surface, the two (12) endpoints of the (13) Holding / release lever operated. The outer (in relation to the rotational movement) (12) End points of the holding / release lever are bolt-shaped and slightly above the level of the (15) bottom bracket inner part (ball-bearing, rotating). This leads to the solution of the (13) holding / release lever via the (16) Lever deflection points from the (17) sleeve / lever snap-in holes, what in turn, the (18) preloaded springs (spring accumulator) relaxes. alternative can the (13) holding / release lever also via (7) electromagnet from the (17) Sleeve / lever latch to be solved. Power is supplied externally via (32) Power cable or could also be made inductively by the rotational movement. The end points of the retaining lever in the (17) sleeve / lever latch are Beveled on both sides, suitably constructed as a counterpart to the sleeve opening and hardened to prevent material abrasion. On the outside End points of the prestressed springs is in each case a (19) spring guide plate mounted, which guides the spring at the defined travel within the (20) spring sleeves is used. At the inside end point of the prestressed springs these are attached to a central (21) spring / sleeve mounting disc. At the (19) spring guide plate are the cables on mounted (22) Seileinhakösen for decoupling of the bottom bracket rotation movement Attached pedal clip. Due to the now released traction (23) Clip retaining bolt (which is held by the (28) clip spring) on the (24) Pedals and thus the connection between (24) pedals and shoes solved. The (18) preloaded spring thus acts as an opponent to the (28) clip spring. To When triggered, the mechanism is manually selected by the user via (25) Reset tension spring and associated (26) reset tension spring lever reactivated and Thus, at this time not (18) biased springs again prestressed and by the (27) lever springs in the (17) Sleeve / lever latch opening fixed. The (26) reset puller lever for the Operation of the (25) return tension spring can be either permanently mounted or be removable.

Drawing 3: Represents schematically a so-called Combi-Clippedal dar. The illustrated (29) clip cover plate can also be analog for all clip systems on the market. The (29) Clip cover plate is by means of (30) elastic drawstrings and (31) Fixing hook fixed to the (24) pedal.
