DK 169373 B1

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a built-in integrated locking system for bicycles, as set forth in the preamble of KRAV 1. A locking system for bicycles with a foot-operated hub brake acting on the rear wheel and of the kind in which a locking cartridge is inserted in the bicycle's swivel tube as when turning a key. locks both the crank and handlebar in one and the same locking function under the influence of a double 10 pawl rod (10) placed in the swath pipe. -

The object of the invention is to lock and hold the vital parts of the bicycle so that a theft of the bicycle with subsequent use of this or its parts does not make the thief want to steal bicycles with this particular type of locking, as the lock prevents the use of the bicycle and separation of handlebars, cranks and rear wheels.

This object is achieved according to the invention by a double locking device for bicycles of the kind specified in the preamble of KRAV 1 and with the characteristics specified in the characteristic part of KRAV 1.

After mounting the cartridge in the swath through a hole in the crankcase, the lock to the rear wheel is mounted. First, install the fiber bush closest to the rear wheel assembly. Then the bushing is mounted at the crankcase. , When the brake lever is mounted, it is held in place by inserting the hole-designed split into the rear pipe. Then the spring-loaded steel wire is inserted through the front bushing and through the bushing with split, after which the rear wheel is PERMANENTly locked. The crank can be fitted with 30 shafts.

The 1 mm thick flexible cut steel cylinder has positioned on the outside the post-mounting hole, pawl hole at the swath tube and the mounting hole at the rear pipe- a thin sliding locking device having the following function: 2.

DK 169373 B1 When the bicycle is locked, - the pile on the crane - the pile goes into a hole in the locking device and holds it tight. The locking device has a 'extruded' pin at the back tube hole which holds the spring loaded steel wire in place in the back tube in the correct position.

5 The locking device is controlled and turned by the bottom plug locking, which in one and the same function hermetically closes the mounting hole and with the bike in unlocked condition, allows the locking device to rotate and release from the pallet locking and release the spring-loaded wire to 10 rear pipes from the split, so that if desired. can be removed and the rear wheels removed.

When the rear wheel has to be locked again, this is done simply by inserting the split and turning the bottom plug into place, after which the wire again engages the split and retains the brake arm.

- f *

It is only possible to turn the bottom plug when the bicycle is unlocked, as the pile in the hole in the locking device makes it impossible to displace the locking device.

20 In the crank, the crank is mounted so that it locks the pedals in the up and down position, which eliminates the vandalism possibilities substantially, since a downward thread will not affect the locking function in particular, and a transverse thread will only affect the braking function without damage.

The invention is explained in more detail below with reference to the drawings, in which: FIG. 1 shows the crankcase w / bottom plug, locking for the rear pipe, as well as the locking function from the swath pipe.

FIG. 2 shows the brake arm as seen from the side.

FIG. 3 shows the rear pipe w / rear wheel suspension seen from the side with brake lever, split, steel wire and split mounted.

Third

DK 169373 B1 FIG. 4 shows rear pipe with brake lever, split, bushing and wire in locked position from above.

FIG. 5 shows the rear pipe piece with brake arm, split and bushing seen 5 in section.

FIG. Figure 6 shows the front locking for the rear pipe and the swath pipe lock for the crank. In addition, the steel cylinder intended for crane housing is shown in plain with the slidable locking device, bottom propshaft, hole for pawl from slotted tubes and hole for spring loaded rear pipe wire.

FIG. 7 is a sectional view of the steel cylinder with the locking device and the extruded release pin for the spring loaded rear pipe 15 wire.

FIG. 8 shows the bottom plug lock seen from the inside.

FIG. 9 is a sectional view of the bottom plug lock.

FIG. 1 shows the crankcase with bottom plug (15), the spring-loaded locking for the rear pipe (12) and the locking cartridge (2) from the swath pipe.

The bottom plug (15) is operated by the handle (16), which in the locked position holds the pawls (14) in the outermost position, while the locking device (7) is in a position where it holds spring (8) for rear pipe (12). in place.

Upon rotation, the pawls (14) are released and the pins (13) move the locking device (7) (the bike is unlocked) free of the spring-loaded pawl (8), which then releases the lock at the rear wheel.

In the rear pipe the bush (10) is seen, in which the spring-loaded pawl (8) at spring (9) controls the steel wire for the rear pipe (12). In the swath tube the adjusting nut (6), pawl rod (3), pawl (4) and pawl holder 35 (2) are seen. The cylinder (1) is also visible.

4th

DK 169373 B1 FIG. 2 shows the brake arm (19). To follow the rear wheel profile, the arm is curved (17). The hole (18) serves for insertion of a split and is round, thus enabling rear wheel alignment. The cutter (20) serves for the adjustment.

5 FIG. 3 shows the rear wheel closure, where (22) is suspended (23) the wheel hub is enclosed by the brake arm (19) held in place in the hole (18) by the split (24) in the bush (21) permanently held by the steel wire (1i) in the the back tube (12). The square (25) serves 10 to the advantage of the splitter (24), with a corresponding square cut made on the splitter, to keep it in position with the hole in the direction of the wire.

FIG. 4 is a top view of the rear pipe (12), the wire (11), bushing (21) and the brake arm (19) and the split (24).

FIG. 5 shows sections of the bush (21), inserted split (24) and simultaneously locked brake arm (19). Also seen is the split (24) with square cutter and wire holes.

FIG. 6 shows the cylinder (1) withstand the plane. The two rear pipes (12) are shown in which one is lock-mounted. Here (11) is the steel wire for the rear wheel, the bushing (10) holds the spring (9) and pawl (8) in place in the rear pipe (12).

25 The swivel tube with pawl holder (2), pawl (4), adjusting nut (6) and pawl rod (3) is indicated in the correct position.

The bottom plug (15) is indicated with the closing posts (14) closed and the locking device (7) in the locked position, the hole (28) being caught by the pawl (4) from the swath tube and the hole (29) locking the pawl (8). that is, when the bicycle is unlocked, - the pawl (4) in the hole (28) is gone, the handle (16) of the bottom plug (15) can be activated and turned to release the rear wheel locking.
