Description

Technical area:

The The invention relates to a brake light device with a Brake mechanics.

State of the art:

From the DE 44 46 098 C2 is a distance warning system for bicycles known which emits a light signal when braking the bicycle. This is triggered by an acceleration sensor, which detects the deceleration process based on the associated negative acceleration. This system is only partially suitable for a function as a brake light, since the light signal is output only during braking, but not when the bicycle is stationary. Furthermore, the acceleration sensor of this system is expensive, which is detrimental not only to the manufacturing cost, but also to the risk of theft. In addition, the wiring effort for this system is relatively large, not least because of the need to provide a supply voltage for the acceleration sensor. Since, moreover, the acceleration sensor must be fastened in a directionally stable position relative to the bicycle, the mechanical outlay for this system is not insignificant either.

The return springs 7a . 7b practice between the runner 6 and the runner counterpart 8th a repulsive force, causing the runner's counterpart 8th up against the spacers A and the runners 6 down against the drivers 5a . 5b is pressed.

In the middle of the runner 6 is a first tubular sliding body 11 admitted. This one is with the runner 6 rigidly connected and towers above it. At the upper end of the first slider 11 a permanent magnet M is attached.

The runner counterpart 8th becomes from top to bottom center of a second tubular sliding body 12 projects through. This one is with the runner counterpart 8th rigidly connected and towering over the same up and down. In the area of the upper end of the second slider 12 is attached as a brake light switch, a reed switch S, which in the 1 to 3 not shown in cross-section, but in plan view and in particular may be designed as Ultraminiatur-Reed sensor.

The first slider 11 protrudes telescopically into the second slider 12 in; the axles are both sliding bodies 11 . 12 aligned with each other.

The drivers 5a . 5b are as collars 5a . 5b formed and lie with its bottom in each case to a spacer AH, wherein each of the two brake cables 3a . 3b from top to bottom by one of the spacers AH is performed.

With each of its lower end face, each of the spacers AH abuts on the upper end face, respectively 9a ' . 9b ' an additional rope sheath 9a . 9b , where the left brake cable 3a in the lower part of 1 in the manner of a Bowden cable within the additional cable sheath 9a runs. Likewise, the right brake cable runs 3b in the lower part of 1 in the manner of a Bowden cable within the additional cable sheath 9b ,

From the brake light switch S project up two lines 23 . 24 out, which lead to a not shown power source or to a brake light, not shown, wherein the power source, the brake light and the brake light switch are connected in series, so that the brake light illuminates with the brake light switch S closed and not lit when the brake light switch S open.

In the situation of 1 is the distance between the magnet M and brake light switch S so large that the field strength of the magnet M at the location of the brake light switch S is not sufficient to close the brake light switch S, so that the brake light switch S is not closed and the brake light is not lit.

Between the spacers A on the one hand and the spacers AH on the other hand is a spacer sleeve 10 arranged, which acts as a stop against a reduction in the distance between the lower ends 4a ' . 4b ' the rope coats 4a . 4b and the upper front ends 9a ' . 9b ' the additional rope coats 9a . 9b , Within the spacer sleeve run both brake cables 3a . 3b in the axial direction of the spacer sleeve 10 ie from top to bottom.

The runner 6 , the runner's counterpart 8th , the return springs 7a . 7b and the drivers 5a . 5b are all inside the spacer sleeve 10 arranged, which thus also acts as a housing for these components.

By pressing the front handbrake lever of the bicycle, the left brake cable becomes 3a deflected upward and thus actuates the brake mechanism. The left driver 5a takes on the deflection of the left brake cable 3a Part, because it is non-slip and thus motion coupled with this. This will be the runner 6 at deflection of the first brake cable 3a under compression of both return springs 7a . 7b from the driver 5a up along the brake cables 3a . 3b moved in parallel, leaving the runner 6 at the deflection of the left brake cable 3a also participates. This upward movement is in 1 indicated by two dotted arrows.

At this upward movement also takes the first slider 11 with the magnet M, so that it approaches the brake light switch S. This approach movement is in 1 indicated by a solid arrow.

2 illustrates a situation in which the front brake of the bicycle is operated and thus the left brake cable 3a is deflected upwards from its rest position. Therefore, there is the driver 5a in 2 in a position opposite to its position of 1 is raised. This is the runner 6 opposite to his position of 1 moved up parallel, causing the return springs 7a . 7b both opposite to the situation of 1 are more compressed and the first slider 11 with the magnet M also in a relation to the situation of 1 is raised position. As a result, in turn, the distance between the magnet M and brake light switch S is so far reduced that the brake light switch S is now closed by the magnetic field of the magnet M and the brake light, not shown, lights up.

Of the Brake light switch S is designed as a reed switch S and on to address the magnetic field of the magnet M capable, through Actuate the brake mechanism, a relative movement between the brake light switch S and the magnet M is caused by which the mutual Situation of the same changed so that the brake light switch S is closed when the brake mechanism is actuated and at unacknowledged Brake mechanism open is. The brake light L therefore lights up when the brake mechanism is activated.

After the end of the deflection of the right brake cable 3a returns the driver 5a in his in 1 shown position (if the right brake cable is still in its rest position). Due to the restoring force of the return springs 7a . 7b the runner follows this return movement of the driver 5a and also returns to his in 1 shown position, whereby the magnet M again in its rest position of 1 returns. Thus, the distance between the magnet M and brake light switch S increases again on the in 1 shown distance so that the brake light switch S opens and the brake light goes out.

3 illustrates completely analogous to the situation of 2 a situation in which, instead of the right, the left brake cable 3b , Is deflected out of its rest position by pressing the rear handbrake lever of the bicycle. This is the right driver 5b opposite to his position of 1 raised. Again, therefore, is the runner 6 shifted parallel upwards; both return springs 7a . 7b are again more compressed than in 1 and the distance between the magnet M and brake light switch S is again reduced so far that the brake light switch S is now closed by the magnetic field of the magnet M and the stop lamp, not shown, lights up.

The magnet M thus takes according to the invention in deflecting the right brake cable 3a participate in the movement (provided the left brake cable 3b in rest position) and when deflecting the left brake cable 3b participate in its movement (provided the right brake cable 3a is at rest).

When deflecting both brake cables 3a . 3b at the same time take the runner 6 and the magnet M participates in the movement of the brake cable having the greater deflection. The brake mechanism is thus according to the invention by deflecting the first brake cable 3a or the second brake cable 3b or at the same time both brake cables 3a . 3b from their rest position operable. According to the invention, the brake light switch S is thus opened when the brake mechanism is not actuated and can be closed by actuating the brake mechanism.

The 4 to 13 refer to a second embodiment of the invention, which also has these advantages. The function of in the 4 to 11 illustrated second embodiment of the invention corresponds substantially to that of the first embodiment, to which the 1 to 3 Respectively.

Also in 4 shown sections of both brake cables 103a . 103b run parallel to each other. The rope coats 104a . 104b each end in the anvil of the corresponding hand brake handle or brake lever (not shown), wherein the brake cables 103a . 103b each movable end in the corresponding handbrake handle or brake lever.

In 4 are both brake cables 103a . 103b in undeflected state, ie in its rest position shown. The brake mechanism is thus in the situation of 4 unconfirmed.

The left brake cable 103a runs in the upper part of 4 in the manner of a Bowden cable within a cable sheath 104a , which with its lower front end 104a ' on a spacer AH ', through which the brake cable 103a from top to bottom. Likewise, the right brake cable runs 103b in the upper part of 1 in the manner of a Bowden cable within a cable sheath 104b , which with its lower front end 104b ' on a further spacer AH 'abuts, through which the brake cable 103b from top to bottom.

With their lower end faces, the spacers AH 'each encounter a runner counterpart 108 through which both brake cables 103a . 103b are also performed from top to bottom. Below the runner's counterpart 108 is at a distance from this one runner 106 through which both brake cables 103a . 103b are again performed from top to bottom.

Below the runner 106 are at this without intermediate space adjacent two drivers 105a . 105b arranged, with the left brake cable 103a through the left driver 105a from top to bottom and the right brake cable 103b through the right-hand carrier 105b from top to bottom. Every driver 105a . 105b is at the respective brake cable 103a . 103b clamped with a fixing screw K 'non-slip, so that he with the respective brake cable 103a . 103b is motion coupled and thus the deflection of the respective brake cable 103a . 103b upwards follows.

In contrast, the runner 106 and the runner counterpart 108 not on the brake cables 103a . 103b attached, but postponed to this without attachment and against these slidable in the longitudinal direction. Between the runner 106 and the runner counterpart 108 are the brake cables 103a . 103b each of a spiral return spring 107a . 107b surrounded, which are not shown in cross-section, but in plan view and therefore in 4 partially cover the brake cables and are partly covered by the brake cables. The return springs 107a . 107b practice between the runner 106 and the runner counterpart 108 a repulsive force, causing the runner's counterpart 108 up against the spacers AH 'and the runners 106 down against the drivers 105a . 105b is pressed.

At the runner 106 is by means of a fixing screw K '' a first tubular sliding body 111 rigidly arranged. The in the 4 and 6 Not shown Fxierschraube K '' does not penetrate into the interior of the slider 111 one. In lower end of the slider 111 is within the same as a brake light switch, a reed switch S 'attached.

At the runner counterpart 108 is a second tubular slider 112 rigidly arranged. This has an internal thread, in which in the lower end of the slider 112 an adjusting spindle J is screwed. At this a permanent magnet M 'is attached via a holder H. By means of the adjusting spindle J is the position of the magnet M 'in the longitudinal direction of the slider 112 adjustable against this.

The first slider 111 , the brake light switch S ', the second slider 112 , the holder H and the magnet M 'are not in that cross-sectional plane of 4 to which reference has heretofore been referred (and which will be referred to as first cross-sectional plane Q1 in the following) but are based on the drawing plane of FIG 4 arranged in front of the first cross-sectional plane Q1.

The first slider 111 , the brake light switch S ', the second slider 112 , the holder H and the magnet M 'are still in for clarity 4 shown, with the exception of the adjusting spindle J and the holder H also in cross-sectional view. The adjusting spindle J and the holder H are shown in plan view.

The axes of the first slider 111 , the brake light switch S ', the second slider 112 , the holder H and the magnet M 'lie in a second cross-sectional plane Q2 and clamp them on. The axes of in 4 shown sections of the brake cables 103a . 103b clamp the first cross-sectional plane Q1. 4 thus shows the first and the second cross-sectional plane Q1, Q2 at the same time (cf. 12 ).

The Heads shown in plan view the fixing screws K 'are located neither in the first nor in the second cross-sectional plane Q1, Q2 and are for reasons the vividness nevertheless shown.

The one behind the slider 111 lying, hidden by this section of the brake light device is in 4 not shown for the sake of clarity.

These statements apply completely in accordance with the 6 and 8th , which also refer to the cross-sectional planes Q1 and Q2 at the same time. The spatial arrangement of the slider 111 opposite the runner 106 goes out too 10 out.

The second slider 112 protrudes telescopically into the first slider 111 in; the axles are both sliding bodies 111 . 112 parallel to the in 4 illustrated sections of the brake cables 103a . 103b and cussing with each other.

The drivers 105a . 105b are formed as adjusting rings and lie with their underside each to a respective spacer AH '', wherein each of the two brake cables 103a . 103b from top to bottom through one of the spacers AH '' is performed.

Each of the spacers AH "abuts on the upper end face with its lower end face in each case 109a ' . 109b ' an additional rope sheath 109a . 109b , where the left brake cable 103a in the lower part of 4 in the manner of a Bowden cable within the additional cable sheath 109a runs. As well runs the right brake cable 103b in the lower part of 4 in the manner of a Bowden cable within the additional cable sheath 109b ,

A brake light L is on the brake light switch S 'and lines 120 . 121 . 122 connected to a power source Q and therefore lights when the brake light switch S 'is closed, which is open when the brake mechanism is not actuated and can be closed by actuating the brake mechanism.

The Brake lamp L can e.g. a light bulb or be a super bright red LED.

In the situation of 4 is the distance between the magnet M 'and brake light switch S' so large that the field strength of the magnet M 'at the location of the brake light switch S' is not sufficient to close the brake light switch S ', so that the brake light switch S' is not closed and the brake light L does not light up.

Between the spacers AH 'on the one hand and the spacers AH''on the other hand is a spacer sleeve 110 arranged, which acts as a stop against a reduction in the distance between the lower ends 104a ' . 104b ' the rope coats 104a . 104b and the upper front ends 109a ' . 109b ' the additional rope coats 109a . 109b , Within the spacer sleeve run both brake cables 103a . 103b in the axial direction of the spacer sleeve 110 ie from top to bottom.

The brake mechanism is by deflecting the first brake cable 103a or the second brake cable 103b or at the same time both brake cables 103a . 103b from their rest position operable.

By pressing the front handbrake lever of the bicycle, the left brake cable becomes 103a deflected upward and thus actuates the brake mechanism. The left driver 105a takes on the deflection of the left brake cable 103a Part, because it is non-slip and thus motion coupled with this. This will be the runner 106 at deflection of the first brake cable 103a under compression of both return springs 107a . 107b from the driver 105a up along the brake cables 103a . 103b moved in parallel, leaving the runner 106 at the deflection of the left brake cable 103a also participates.

At this upward movement also takes the first slider 111 with the brake light switch S 'so that it approaches the magnet M'. Trained as a reed switch brake light switch S closes when its distance from the permanent magnet M falls below a threshold, and opens when this distance exceeds the limit again. The limit value can be changed by adjusting the adjusting spindle J. He is set so that the limit falls below a certain minimum deflection of one of the two of the brake cables from its rest position by pressing the brake mechanism and the transition of the brake cable back to the rest position after falling below the minimum deflection is exceeded, if that other brake cable is still in its rest position. By adjusting the adjusting spindle J, the minimum deflection is changed at the same time.

5 illustrates in cross-section the arrangement and the situation of 4 in a line of vision, which in 4 the direction from right to left corresponds, so only the in 4 right brake cable 103b in 5 is visible, with the brake mechanism is also in the unactuated state. The driver 105b is in 5 across from 4 rotated 90 ° about its axis, so that the fixing screw K 'in 5 can also be seen in plan view.

By means of in 4 Fixing screw K '', not shown, is the slider 111 rigid at the runner 106 clamped. The brake light switch S 'is in 5 across from 4 also shown rotated by 90 °.

In 5 is also an in 4 not shown, to the sliders 111 . 112 parallel guide rod F shown, which preferably in the runner counterpart 108 firmly and rigidly absorbed and by the runner 106 is carried out without being firmly connected to this. The runner 106 therefore slides upon actuation of the brake mechanism along the guide rod F in the direction of the runner counterpart 108 , The guide rod F is used together with the sliders 111 . 112 to guide the movement of the runner 106 and to prevent jamming and the orientation of the runner 106 opposite the runner counterpart 108 to keep constant.

The first slider 111 , the brake light switch S ', the second slider 112 , the guide rod F, the holder H and the magnet M 'are not in that cross-sectional plane of 5 to which reference has heretofore been referred (and which will hereinafter be referred to as the third cross-sectional plane Q3), but are based on the drawing plane of FIG 5 arranged behind the third cross-sectional plane Q3.

The first slider 111 , the brake light switch S ', the second slider 112 , the guide rod F, the holder H and the magnet M 'are still in for clarity 5 shown, with the exception of the adjusting spindle J and the holder H also in Querschnittsdarstel development. The adjusting spindle J and the holder H are also in 5 shown in plan view.

The axes of the first slider 111 , the brake light switch S ', the second slider 112 , the holder H and the magnet M 'lie in a fourth cross-sectional plane Q4 and clamp them on. 5 thus shows the third and the fourth cross-sectional plane Q3, Q4 at the same time (cf. 12 ).

The heads of the fixing screws K ', K "shown in plan view are located neither in the third nor in the fourth cross-sectional plane Q3, Q4 and are for reasons of clarity in 5 nevertheless shown. The spacer sleeve 110 is in 5 in the region of the guide rod F for reasons of clarity not shown.

These statements apply completely in accordance with the 7 and 9 , which also refer to the cross-sectional planes Q3 and Q4 at the same time.

6 illustrates a situation in which the front brake of the bicycle is operated and thus the left brake cable 103a is deflected upwards from its rest position. Therefore, there is the driver 105a in 6 in a position opposite to its position of 4 is raised. This is the runner 106 opposite to his position of 4 moved up parallel, causing the return springs 107a . 107b both opposite to the situation of 4 are more compressed and the first slider 111 with the brake light switch S 'also in a relation to the situation of 4 is raised position. As a result, in turn, the distance between the magnet M 'and brake light switch S' is so far reduced that the brake light switch S 'is now closed by the magnetic field of the magnet M' and the brake light L lights. The brake light L thus lights up only when the brake mechanism is activated.

7 also illustrates a situation with the brake cable deflected 103b and thereby actuated brake mechanism and luminous brake light L, the viewing direction of those of 5 corresponds and the deflected brake cable 103b opposite to the 6 shown situation is further distracted from his rest position.

8th illustrates a situation in which the brake cable 103b is deflected out of its rest position, with the line of sight of the 4 and 6 equivalent. Both return springs 107a . 107b are maximally compressed. The distance between the brake light switch S 'and the magnet M' is even lower than in the situations of 6 and 7 , so that the brake light L also lights up.

The fixing screw K '' is opposite to the 5 . 7 and 9 90 ° around the axis of the slider 111 shown rotated. The in 8th shown in plan view head of the fixing screw K '' is located neither in the first nor in the second cross-sectional plane and is for reasons of clarity in 8th nevertheless shown.

9 illustrates the situation of 8th , where the line of sight of those of 5 and 7 corresponds and the deflected brake cable 103b is also maximally deflected from its rest position.

The functionally to the (not shown in the figures) bicycle brake leading direction of the brake cables is in the 6 and 8th each marked with a downward-pointing triangular arrow. The functionally to the (not shown in the figures) brake levers leading direction of the brake cables is in the 6 and 8th each marked with an upward-pointing triangular arrow.

After the end of the deflection is again the situation of 4 achieved, provided the left brake cable 103a is still in its rest position, so that the brake light switch S 'opens and the brake light L goes out.

In complete analogy to the situations of 6 to 9 is in place of the right brake cable 103b the left brake cable 103a deflectable. The effects on the position of the runner 106 , the compression of the two return springs 107a . 107b and to the distance between the brake light switch S 'and magnet M' completely correspond to that of a deflection of the right brake cable 103b ,

Even after the end of the deflection of the left brake cable 103a will again the situation of 4 achieved, provided the right brake cable 103b is still in its rest position, so that the brake light switch S 'opens and the brake light L goes out.

Likewise, the brake mechanism can be actuated by both brake cables 103a . 103b be deflected simultaneously. Again in complete analogy to the situations of 6 to 9 corresponds to the effect of a deflection of both brake cables on the position of the rotor 106 , the compression of the two return springs 107a . 107b and to the distance between the brake light switch S 'and magnet M' completely that of a deflection of either the right brake cable 103b or the left brake cable 103a , depending on which of the two brake cables is further deflected.

The brake mechanism is thus according to the invention either by deflecting the left brake cable 103a or by deflecting the right brake cable 103a or by simultaneous deflection of both brake cables 103a . 103b operable; in all three cases closes the brake light switch S 'and thereby brings the brake light L to light.

10 shows a 3D representation of the runner 106 with the rigidly arranged first slider 111 , The viewing direction of 10 corresponds essentially to the direction of the runner counterpart 108 to the runner 106 (see. 4 . 6 . 8th ), however, is inclined against this direction by about 30 °, leaving the runner 106 in 10 not in the in the 4 . 6 and 8th from top to bottom extending viewing direction can be seen, but in a deviating from this by about 30 ° direction. For receiving the first slider 111 points the runner 106 one in the 4 to 9 not shown enclosure 206 on which part of the runner 106 is and in which the slider 111 is included. In 10 is only the forward of the enclosure 206 outstanding part of the slider 111 shown. The runner 106 also has a bore B for the passage of the guide rod F (see. 5 . 7 and 9 ).

11 shows a 3D representation of the runner's counterpart 108 , the viewing direction of those of 10 equivalent. For receiving the second slider 112 which is in 11 not shown, has the runner counterpart 108 one in the 4 . 6 and 8th not shown enclosure 208 on which part of the runner's counterpart 108 is. The runner counterpart 108 also has a bore B 'for receiving the guide rod F (see. 5 . 7 and 9 ).

12 shows a plan view of the rotor counterpart of 11 , where the direction of view of the direction from top to bottom in the 4 . 6 and 8th with the above-explained cross-sectional planes Q1, Q2, Q3 and Q4 in FIG 12 are drawn. The cross-sectional planes Q1, Q2, Q3 and Q4 all run parallel to those in the 4 to 9 illustrated sections of the brake cables 103a . 103b ,

13 shows a not to scale cross-sectional view of the spacer sleeve 4 to 9 , wherein the cross-sectional plane perpendicular to the in the 4 to 9 illustrated sections of the brake cables 103a . 103b runs.

According to the invention is thus the brake light switch S 'at not activated Brake mechanism open and by pressing the brake mechanism closable.

Of the Brake light switch S or S 'speaks So according to the invention to a Actuate each of the two hand brake lever of the bike and brings the brake light at all by operation or bicycle brakes conditional braking operations for To shine. Advantageously, therefore, according to the invention only one Brake light switch and only one magnet and also only one, very simple, branchless circuit with only one power source and only one brake light required to the following traffic signaling a deceleration of the bicycle, it does not matter whether the bike with its front brake or with its rear brake or braked together with both brakes. The brake mechanism according to the invention let yourself therefore particularly cost-effective produce and with great Operate safety.

The low production costs and thus realizable low Sales prices for a brake light device according to the invention In particular, they also have a reducing effect on the theft risk, when the brake light device according to the invention attached to a bicycle.

The execution the brake light switch as a reed switch S or S 'and its triggering with the Magnets M and M 'ensure a non-contact Operation of the brake light switch, long life and great resistance Against pollution.
