According to claim 1, Fig. 7 shows the view of the device, Fig. 8 shows in principle the interaction of the various parts between the lever (1) and the round transport element (7) according to claim 1, Fig. 1, 2 and 3 show further essential elements according to claim 1.

The housing (21) has a handle-shaped end and a mounting plate (11). The housing (21) accommodates the round transport element (7) inside, as well as the pull-out part (5), which can, however, leave the housing through the openings (10, 12, 13). The round transport element (7) is seated on the drive shaft (22) in a rotationally fixed manner and is driven by it. The drive shaft (22) is inserted vertically through a hole in the housing base and in the housing cover and guided by bearings there. The drive shaft (22) is driven by the lever (1) by means of a double-acting ratchet (23) and a manually released coupling (24). Fig. 8 shows an advantageous arrangement in which the double-acting ratchet (23) is divided into two functional parts, with a

j housing (21) is attached to each part. The lever (1)

is mounted so that it can rotate around the center of the drive shaft (22). It is pushed away by the force of the spring (2) and pressed in by hand. Any type of elastic element of any shape can be used as the spring (2), as long as it exerts an elastic force. The inward and outward movement of the lever (1) thus generated is converted into a rotary movement of the drive shaft (22) using the ratchet (23), whereby the ratchet (23) also blocks the drive shaft (22) from moving backwards as a result of the pulling force originating from the pullable part (5). This locking takes effect when the process of pushing down the lever (1) is interrupted, and thus prevents the pullable part (5) from moving backwards unintentionally if a pulling force is exerted from there. If this movement backwards is to be made possible, the clutch must The coupling (24) connects and

releases the rear part of the ratchet (23) from the housing. :&Egr;&egr;icösirien; the two known ratchet types are used

Are, like the radially acting ones with internal or external teeth, or also axially acting ratchets. A ratchet with external teeth is shown

The known types of clutch can be used^ such as single-disk clutch* multi-disk clutch* a band brake placed around a friction wheel or a detachable connection based on the drum brake principle* shown in Fig. &dgr; and a single-disk clutch is preferred. Here, the one ring-shaped clutch disc (56) is firmly connected to the ring of the ratchet (23)^ which supports against reverse movement.

which rests axially against the housing wall.

The counter disk (57) of the clutch (24) is axially displaceable and non-rotatably mounted on the drive shaft (22). To engage the clutch, it is pressed by the spring (55), and to disengage it is pressed against the spring (55) by the lever (53). The spring (55) rests against the cap (54), which is attached to the housing (21).

[ The drive shaft (22) is preferably designed in cross section as

dratic (according to claim 1, hexagonal according to claim 2 or with a longitudinal groove according to claim 3), whereby the fastening of the various drive and braking elements is facilitated.

Fig. 9 shows the internal drive mechanism according to claim 4, 5. According to claim 4, the pullable part (5) consists of rigid material, according to claim 5 the pullable part (F) consists of flexible material. The round transport element (7) is equipped with a spur gear (25) on the running surface, the pullable part (5) is designed as a rigid rack by using a gear (26), the teeth (25 and 26) being in constant engagement. The pullable part (5) is guided in the direction of movement by guide elements, preferably lateral guide cams and a lower sliding bed. Fastening elements are provided at the ends to hold the goods to be pulled, which are shown here in the form of a fastening hole (27). A fastening hole (27) is provided at the front end of the pullable part (

i· 1 5 ·-'

A lock (28) to be attached can prevent the clutch (24) from accidentally running out when opening. The arrangement according to claim 4, 5 results in a particularly high power transmission. When using flexible material according to claim 5 for the element designed as a rack, it is possible to guide it as a pullable part (^y) in a direction deviating from the straight line, similar to the use of a band or rope.

Fig. 4 and 5 show the part of the device that is directly required for transporting the pullable part (5) according to claim 6 as a section of the device. The gear wheel(s) (19) that are fixedly attached to one or both outer sides of the round transport element (7) are in constant engagement with the gear wheels (19) of the same size that are fixedly attached to the one or both outer sides of the clamping roller (6), which forces the clamping roller (6) to run synchronously in opposite directions with the round transport element (7), so that the pullable part (5) that is passed through between them is pulled. The contact force against the pullable part (5) that is required for the friction force required for this is generated by the rollers (6, 7) being hollow and made of a flexible material. Fig. 4 shows the recording of a thin, Fig. 5 that of a thick drawable part (5), whereby advantageously the friction force also increases with increasing thickness of the drawable part.

Fig. 1, 2 and 3 show the device according to claim 7, whereby Fig. 1 shows the lever (1) in the most open end position, Fig. 2 shows the position of the lever (1) pressed in as far as possible during the tightening process. Fig. 3 shows how the lever (1), which has been released as a result of the displacement of the locking plate (16), has now reached the absolute lowest position and in doing so moves the push rod (18) against the spring pressure of the spring (8) via its cam (20), whereby the clamping roller (6) is pushed back and the pullable part (S) is thereby released.

clears the way for the return movement. Any type of elastic element in any shape can be used as a spring (8), as long as it exerts an elastic force.

Fig. 10 shows, according to claim 8, the affected section of the device, which is now referred to under claim 8 by the rocker arm (36) instead of the push rod (18) that is eliminated according to claim 7. The rocker arm (36) can be tilted about the axis located at its lower end, is tilted to the left by the cam (20) of the lever (1) when it is pressed down, beyond the hold released when the locking plate (16) is pushed to the right, and pushes the clamping roller (6) away from the transport element (7) through its end part.

Fig. 6 shows the section of the device according to claim 9 that is directly required for transporting the towable part (5).

The arrangement of the gears (33, 30, 31 and 34) and their constant engagement, via the rotationally fixed connections of the gear (33) with the round transport element (7) and that of the gear (34) with the clamping roller (6), cause the clamping roller (6) and the round transport element (7) to inevitably move against each other in such a way that they pull the pullable part (5) lying between them together. The rocker (32) is pressed towards the round transport element (7) with the help of the spring (8). Any type of elastic element in the form can be used as a spring, as long as it exerts an elastic force. By pressing the rocker (32) back against the line of action of the spring (8), the clamping roller (6) is moved away from the round transport element (7), so that the path of the pullable part (5) is cleared. The free end of the swing arm (32) protrudes from the housing (21) and thus serves as a handle for pushing back. In order to achieve the advantageous synchronous running for the transport of the pullable part (5)*, the gears (33 and 34) must have the same number of teeth* Due to the arrangement

The positioning of the axis of the gear wheel (31) together with the bearing axis of the rocker arm (32) beyond the connecting line with the axes of the gear wheels (33 and 34) on the side from which the towable part (5) is intended to be transported has the particularly advantageous effect that the contact pressure exerted by the spring (8) is automatically increased in a metered manner ^depending on the tensile force applied to the towable part (5).

Fig. 11 shows a detail of the part of the device according to claim 10 that is directly required for transporting the towable part (5).

The arrangement of the gears (33, 30, 31 and 34) and their constant engagement, via the three-point connection of the gear (33) to the round transport element (7) and that of the gear (34) to the clamping roller (6), cause the clamping roller (6) and the round transport element (7) to inevitably move against one another in such a way that they pull the pullable part (5) lying between them together. The rocker (35) is pressed in the direction of the round transport element (T) with the aid of the spring (8). Any type of elastic element in the form can be used as a spring, as long as it exerts an elastic force. By pressing the rocker (35) back against the line of action of the spring (8), the clamping roller (6) is moved away from the round transport element (7), so that the path of the pullable part (5) is cleared. The free end of the rocker (35) protrudes from the housing (21) and thus serves as a handle for pushing back. In order to achieve the advantageous synchronous operation for the transport of the part to be pulled, the gears (33 and 34) have the same number of teeth. -i the arrangement of the axis of the gear (30) together with the bearing axis of the rocker (35) beyond the connecting line with the axes of the gears (33 and 34) in the direction in which the part to be pulled is intended to be transported, has the particularly advantageous effect that the pressing force exerted by the spring (8) is automatically increased in a metered manner depending on the pulling force applied to the part to be pulled (5,).

The design of the pullable part (5) as a rope mentioned in claim 11 leads to an expansion of the possible uses compared to the racks or toothed belts mentioned in claims 4, 5.

The design of the pullable part (5) as a band mentioned in claim 12 leads not only to the expansion of the possible uses as in claim 11 but also to the possibility of achieving a greater pulling force with otherwise the same equipment.

The shape of the transport element (7) and the Kleram roller (6) mentioned in claim 13 and shown in Fig. 12 by reducing the roller diameter towards the sides causes an automatic adjustment of the pullable part (5) towards the center of the rollers during operation. This advantage is particularly evident when using belts according to claim 12.

The shaping of the transport element (7) and the clamping roller (6) as shown in claim 14 and claim 15 and in Fig. 13, 14 by means of a groove in the running surface or by means of guide disks to be attached laterally improves the guidance of the pullable part (5).

The channels (9) mentioned in claim 16 and partially shown in Fig. 1, 2, 3 ensure the guidance of the element (5) to be pulled within the housing (21).

The mounting plate (11) listed under claim 17 is shown in Fig. 1, 2, 3, 7. With its help, the lever hoist can be attached where it is needed. Nails or screws (17) are shown as an example of a type of attachment.

The connection devices (39) listed under claim 18 are shown in their arrangement and mode of operation in Fig. 15 as an example at the left end of the housing (21).

They allow, for example, installation in a standard boom of a sailboat, if they are attached to both ends of the housing (21). The attachment device (39) is expediently hollow and thus, when placed on a hole in a side wall of the housing (21), allows the pullable part (5) to be inserted inside the attachment device (39) and then inside the boom connected to it.

The connection parts (39) are obtained by integrating the lever hoist into a basic unit, such as the boom in the example mentioned.

The tubular extensions (40) of the housing (21) mentioned in claim 19 are created when the tubular connection device (39) shown in Fig. 15 is extended, as shown at the right end. They run to both sides of the housing I

(21) roughly in the direction of the towable part (5) and can accommodate it. If shaped accordingly, they can be combined to form a boom using commercially available head and end pieces. Lateral holes ₍ 58) are to be made for the lateral exit or entry of the towable part (5).

The cover (45) mentioned in claim 2i is shown in Fig. 11* It consists of the vertical wall parts, which are hatchedj and a cover» the border of which is shown* The cover prevents* the pullable part (5) from jamming in the gear*

The encapsulation (46) mentioned in claim 22 is shown in Fig. 17 as an example of the encapsulation of a gear. It encloses sensitive components and keeps foreign bodies away from them. At least where it has to absorb relative movements between the gear wheel (33 or 30) and the rocker arm (32 or 35), it consists of a flexible material into which bellows are incorporated to improve mobility. The connections on the wheel flanks form a seal.

The casing mentioned in claim 23 serves to enclose the housing (21), ratchet (23) and coupling (24). It can also enclose other parts, provided they are located on the outside of the device. It consists of a foam-rubber-like, dense layer that seals, improves grip and reduces the risk of injury to the user through shock-absorbing properties.

The hold-down device (47) mentioned in claim 24 is shown as an example in Fig. 7. It consists of a folding bracket that can be folded up and down around a joint on the housing (21). When folded back, it does not hinder the movement of the lever (1). If it is folded up and the lever (1) is simultaneously in its lower pressed-down position, it holds the lever (1) down after it has been released. If the lever (1) is to be put into operation again, the hold-down device (47) is folded back over the end of the lever.

Fig. 18 shows a holding down of the lever (1) according to claim 25.

The locking pin (49) is always inserted into the hole (52). If the lever (1) is pressed down, the holes (52, 15) are exactly one above the other. If in this situation the rocker arm (48) is pressed down on the side on which the locking pin (49) is located, the locking pin (49) is pushed into the hole (15) and thus holds the lever (1) in its lower rest position. To restart the device, the end of the rocker arm (48) opposite the locking pin (49) must be pressed down. To make handling easier and safer, the two upper ends of the rocker arm (48) are each equipped with a pressure plate (51).
