Abstract

With the disclosed method it is to be ensured that a relatively long pipe network for heated up or warmed up fluids which is connected downstream of the measuring device does not cool down during relatively long rest periods. This can only be achieved if the line lengths connected downstream of the measuring device are also involved in circulation. In conventional water meters, the circulation throughflow is also measured as consumption so that this method can only be used when a second water meter is used in the circulation line so that the differential consumption is then counted as consumption. Unfortunately, this method has the disadvantage that in the case of unfavourable tolerance measurement incorrect values are obtained which have proven unacceptable in practice. The disclosed method is intended to eliminate these losses, this being achieved in that, as a result of the special design of the measuring chamber, in each case the preliminary flow and feedback are directed in parallel into the measuring chamber, specifically in the same flow direction so that when circulation throughflow occurs a pressure compensation is achieved which brings the measuring wheel to a standstill. The pressure difference does not change in favour of the first runnings until a downstream tapping valve opens so that the impeller carries out a precise measurement. The application comprises two embodiments, specifically on the one hand an embodiment with a dividing web in the measuring chamber and on the other hand an embodiment as a separate measuring chamber with the volume flow being diverted by means of corresponding non-return valves into the actual measuring chamber and being removed from the downstream tapping valves. Both versions are provided with a control device which serves to compensate the pressure loss in the pipe network connected downstream of the measuring device.

Description

Patent short description

Characterization of the invention: system and device of a bicycle pedal lock with function blocking with double theft protection Area of application: The Invention enables a bicycle bottom bracket to be blocked by means of a cylinder pressure lock, the lock cylinder is not the subject of this application.

The invention comprises a locking system for the bottom bracket of Bicycles of all types with double theft protection a) as a built-in element in the bicycle frame construction b) as a retrofit kit for bicycles that have already been manufactured Purpose: The purpose of such a lock is to keep a parked bicycle in the bottom bracket to block in such a way, .that the rotary movement of the pedal bottom bracket is no longer carried out can be.

The construction is also such that by unscrewing both Pedal legs in the locked state of the lock not laterally the bottom bracket can be pulled out of the frame sleeve.

Prior Art: It is well known that bicycle locks secured by built-on pressure locks that protrude into the bicycle spokes here in different versions.

However, these locks have the disadvantage that they can be damaged by the use of force or can be broken open with a suitable tool without great difficulty can and be exchanged for new ones, so that a stolen bike can be recovered is fully functional.

Edition: The invention is based on the following object: A bicycle to secure in the function so that a theft only by removal of the whole Bicycle is possible and only complicating the solution of the lock by-mechanical destruction of the locking mechanism is possible with considerable Effort, with the lock, which is already integrated in the construction of the bicycle is not to be replaced in the old form after such destruction can.

Likewise, the construction of the castle is so designed that it can be used as a retrofit kit for already manufactured bicycles.

Solution: The object is achieved according to the invention in that the actual Locking mechanism for a new bicycle construction in the bicycle frame socket for the bottom bracket, seen from the inside, is inserted in front of the ball bearing. over a The cylinder bushing welded into the frame bushing becomes the actual locking cylinder pressed in and the locking device locked by means of a tension spring.

The actual lock cylinder including the lock pin construction or the locking is not the subject of this application.

By pressing in the lock cylinder, which is not due to spring force When locked, protrudes about 5 cm from the frame construction, the bottom bracket shaft becomes blocked at appropriately shaped points so that a rotary movement of the pedal shaft is no longer possible.

Lock the ScilloS by clicking the lock cylinder xçiid, The keeping of this lock is only possible when the lock is keyed is rotated by 900, so that the bolt or bolts of the lock cylinder in the cylinder socket are locked.

This rotation also achieves axial locking, so that a lateral pulling out of the bottom bracket shaft after dismantling the pedal legs is no longer possible. Further embodiment of the invention: The invention comprises as a locking system two requirements in the form of an installation kit, firmly integrated in the bottom bracket bushing of the frame.

Furthermore, as a replica kit for existing bicycles, whereby only an extended bottom bracket shaft has to be installed.

In addition, three claims via three different locking options the bottom bracket shaft as well as the one device for locking the locking system when the lock is blocked, which in this case causes the locking body to be pulled out horizontally no longer possible when the pedal leg is removed.

Achievable Advantages: The advantages achieved with the invention exist in particular that 1. bicycles inoperable when the lock is locked are and can only be pushed, 2. the bike is locked so compactly, that an expansion of the locking mechanism only by a substantial destruction of the Bicycle frame in the area of the bottom bracket is possible and so the re-use value a stolen bicycle is largely excluded.

3. The possibility is given to also use existing bicycles to equip a retrofit kit with such a lock, 4. the Fuse is 2-fold; so that it can also be pulled out with the pedal legs removed and bored out cylinder is not possible, 5. the locking system, in connection with a commercially available spoke lock, a much improved theft protection without having to accept excessive additional costs! Description of the exemplary embodiments m J? 1r 1: The figure illustrates the installation principle of the pedal bearing lock when it is integrated into the bicycle frame construction. Here the pedal bearing frame bushing (1) is opposite the chainring (2) extended by about 2 - 3 cm. Next to the welded frame tubes the cylinder liner (6) is inserted, the pedals (5) and the pedal arm (4) are locked in a vertical position. The cylinder locking device is in Area between the welded frame tube and the ball bearing (3) of the bottom bracket included in the bicycle construction.

Figure 2: Figure 2 basically shows the same system. In this However, as a retrofit kit for already completed bicycle constructions, with the cover plate (4a) of the bottom bracket removed and the bottom bracket bushing (1) is extended by the lock receiving unit (8). In this case an extended Installed bottom bracket shaft (9). The lock receiving unit (8) is screwed together or connected to the existing frame by spot welding! Figure 3: The figure 3 shows a cross section through the bottom bracket cylinder (1). Here is the function identical for an integrated construction or for a retrofit kit.

The pressed-in lock cylinder (2), which is secured by 2 tension springs (12) is connected to the driver (13) of the driver locking disc (17), pushes likewise down the carrier disk (11) for the closing jaws (15). The main body of the lock (14) is made so that the closing jaws (15) by the spring tension of the jaw spring (16) via the bevel (14a) worked into the base body (14) into the flattened one Locking notch (21) of the bottom bracket shaft is pressed in. For the corresponding Back pressure is provided by the jaw springs (16) - those on the base body (14) and on the closing jaws (15) are attached, which are movably mounted in the bearing shaft (19), the are in turn worked on the carrier cylinder.

Figure 4: The figure shows the locking mechanism with the lock open represent.

The lock cylinder is opened by the counterpressure of the jaw springs (16) (2), guided in the lock bushing (10), with the drive plate (17) around a construction-related Distance pressed upwards so that the closing jaws (15) on the slope (14a) of the base body (14) can be pulled out of the turning circle of the bottom bracket shaft (9).

Since the driver disc (17) is not cylindrical in the Träyerscheibe (11) can be guided, this function is taken over by the round guide pin (18), which is guided in a bore in the carrier disk (11).

The entire locking mechanism is in a prefabricated state, the innards are made by en.sp-echende end plates in the internal thread (@@) ange @@@@@@@ and so close the lock body and protect it from dirt.

FIG. 5: FIG. 5 shows a variant of the locking mechanism represents, wherein the closing jaw (25) from above into a corresponding notch (24) of the The bottom bracket shaft (9) is pressed in. Figure 5 shows the lock in the depressed State so that the bottom bracket shaft (9) is blocked. Compared to the figure 3/4 is here a closing jaw (25) over 2 compression springs (27), which are in the spring bushing (28) are fixed in the lower part of the base body (14) in the relaxed state pushed up (F g. 6).

Figure 6: This figure shows the locking mechanism in the open state.

The compression springs (27) and the closing jaws are relaxed is pushed up by the construction distance by this spring (27), so that the free space for the rotary movement of the bottom bracket shaft (9) is released. Here is with exactly vertical pedal legs the bottom bracket shaft (9) with its Lock notch (24) only in this position in a lockable state.

The driving disc (17) is loose with the locking jaw (25), the lock cylinder (2) being connected by compression springs (27) in FIG. is connected to the driving disc.

The lock cylinder (2) can only be opened with the corresponding Force can be pulled by the driver. The driver disc (17) is guided in the cut cylinder notch (25a) in the closing jaw (25).

FIG. 7: FIG. 7 shows the section through a construction at which the driver disc (3o) and the cylindrical locking pin (31) in one corresponding hole (32) of the bottom bracket shaft (9) is pressed. In closed The state is determined by turning the Lock cylinder (2) above the Driver (the driver locking disc (30) pressed down and held like that that the locking pin (31) locks the bottom bracket shaft (9). The corresponding back pressure is driven by the compression springs (27) via the spring fork (33) onto the drive plate (30) and the lock cylinder (2).

Figure 8: Figure 8 shows the lock in the relaxed and thus open State, with the cylindrical locking pin (31) outside the rotating space of the bottom bracket cylinder (9) and thus enables the rotary movement. Keeping the castle free is guided by the compression spring (27) in the spring @@@ hse (@@, and the spring fork achieved.

FIG. 9: FIG. 9 shows a longitudinal section through the bottom bracket bushing (1) with pressed in and closed lock cylinder (6). The lock cylinder socket (1o) has legs (34) which are elongated downwards in the longitudinal direction and which extend by 900 the rotated driver disc (17) pushes down, locked there and at the same time the horizontal lock via the locking lug (35) on the slave locking disc (17) represents for the entire locking mechanism of all types of construction. Additionally are in the extended legs of the lock cylinder with cylinder notches (36) Let the stop stop the locking pins of the cylinder lock during the closing process be able to record. For this security there is only one patent claim only in the area the cylinder liner is stressed. The entire lock mechanism is pre-assembled State between the two cover disks (37) with one-sided safety screw connection (38) brought together firmly in one piece, pushed into the frame bushing (1) at the side up to the stop lug (39), the lock body (14) shaped so that it forms a tightly guided unit between the outer surface and the bottom bracket bushing, which has a U-shaped opening at the top! 40), which are disks in a connection (37) continues so that the entire body over the protruding into the interior The cylinder liner leg (36) can be pushed out against the stop lug (39).

Then the ball bearing (3) and the end plate (41) are mounted.

Both are not the subject of this application.

Figure 10: Figure 10 shows the connection point of the bottom bracket lock as a retrofit kit for bicycles that have already been manufactured. This is where the end cap on the side opposite the chain pulley and removed the bottom bracket lock with a correspondingly designed bottom bracket sleeve extension (42) with the bottom bracket sleeve (43) of the bicycle frame connected. This connection takes place, depending on the bike construction, Via a molded threaded nipple (44) or wedge nipple (44). The ball bearing (3) Remains in the bottom bracket, but an extended bottom bracket shaft must be installed.

Figure 11: Figure 11 shows the lock cylinder socket according to claim 1, which remains the same for all types of bottom bracket lock, shows the bushing as a single part with the weld-in upper part (45), the cX ~ vriiLg inserted-iüc-tn gc'cjciiLeerring R.ur drive opening (46), in which the driving target (Fig. 12, 13, 14) slide into their relaxed position when the bottom bracket lock is open.

The lock cylinder notches are in the horizontal locking legs (47) (36) incorporated, clearly showing the stop point (48) for the locking pins you can see.

These lock cylinder notches worked into the locking leg (47) are structurally dependent on the cylinder lock, which is not the scope this application belongs.

Hinta: the locking legs (47) on the outside, @@@@@@ @@@@@@@ in the locked state, the locking lug (35) of Figure 12 on both sides, 13 and 14, so that this ensures the horizontal locking of the bottom bracket lock is.

FIG. 12: FIG. 12 shows the drive locking disk as an individual part according to claim 1 with the driver web (13) and the tension spring slots incorporated therein (12), into which the tension spring lock of the cylinder lock not belonging to the application intervenes.

The driver base (48) is designed in its shape so that the Driving disc in the unlocked state of the lock for all claims can slide into the buoyancy opening (46) of the lock cylinder socket.

The exact design of the locking nose can also be seen (35), which from the outside behind the locking leg (47) of the lock cylinder socket engages. The guide pin (49) centrally guides the driver disc in the Castle substructure.

FIG. 13: FIG. 13 shows the driving disc according to Claim 3, which differs from Figure 12 only in that instead of of the guide pin, depending on the design, the drive locking disc with a guide attachment (50) is equipped, the central part of the locking disc base (48) only is extended to. below.

FIG. 14: FIG. 14 shows the driver lock disc according to claim 4, the upper part again being structurally similar to FIGS. 12 and 13 matches. According to the invention, however, is under the locking disc base (48) Locking pin (31) incorporated, which goes directly into the corresponding opening in the bottom bracket shaft engages and so in the locked state of the bottom bracket lock the bottom bracket shaft blocked.
