Figure 4 shows the scrolling device of Figure 3 with the clamping elements in an intermediate position;

Figure 5 shows the scrolling device of Figures 3 and 4 with the clamping element attached to the second clamping position.

Figure 1 shows a bag (1) with a strap (2). The strap (2) can be rolled up via a scrolling device (6). The effective length of the strap (2) can be changed as such. The bag (1) can be used, for example, as a shoulder bag or a handbag. Alternatively, the strap (2) can be rolled up and the strap (2) can be placed directly on the side (42) of the bag (1) so that the bag can also be used as a bag without a strap (2). .

This scrolling device (6) is illustrated in Fig. 2. As can be seen from Figure 2, the scrolling device (6) includes a support housing (36). For larger portions, the scrolling device (6) is disposed inside the bag (1). Only an upper part (37) of the scrolling device and a lower part (39) of the scrolling device are disposed outside the bag (1). Alternatively, the scrolling device can be disposed entirely outside of a bag (1).

In the upper part (37) of the scrolling device (6), the scrolling device (6) includes an opening (38) through which the strap (2) can be introduced into the interior of the support housing (36) . In the lower part (39), the scrolling device (6) has a handle element (28) of the latching member (4). Only the handle element (28) and the opening (38) can be accessed from the outside of the bag.

Figure 3 illustrates a scrolling device (6) that removes a component of the support housing (36). The scrolling device (6) comprises a take-up element (8) through which the strap (2) can be rolled up.

Furthermore, the scrolling device (6) includes a return member (not shown) that can apply a return torque to the take-up element (8) such that by the return torque, the roll is rolled up The element is rotated about the axis of rotation in a first direction of rotation (12) to cause the strap to be wound around the take-up element (8). The strap (2) can be adapted to pull back from the take-up element against the return torque, and when the strap (2) is pulled out, the take-up element (8) can be in a second direction of rotation (14) Rotating, the second direction of rotation is relative to the first direction of rotation (12). For example, the strap (2) can be pulled out by the user by pulling the strap (2).

The scrolling device includes a latching member (4) by which the pull-out and rolling of the strap (2) can be blocked. With the latching member (4), the rolling element (8) can be blocked in any stepless manner so that the pulling and unwinding of the strap can be blocked without clamping the strap.

The blocking member (4) reliably moves the support housing (36) of the scrolling device (6). The latching member (4) includes a transmission housing (30). Furthermore, the blocking member (4) comprises a handle element (28). A retaining member (22) is disposed in the transmission housing (30) for pivotal movement about a pivot (18). Additionally, a first end of a second return element (32) is secured to the transmission housing (30). The return element (32) is a spring element. Alternatively, it can be any other return element that is hydraulic, pneumatic, or electric. Furthermore, the second end of the second return element (32) is fixed to the support housing (36) of the scrolling device (6).

A clamping element (20) is mounted on one side of the holding element (22) relative to the pivot (18) to support rotation about the shaft (16).

The scrolling device (6) further includes a first stop element (24) and a second stop element (26). In the illustrated embodiment, the first and second stop members (24, 26) have a first surface (24a) and a second surface (26a). As illustrated, the first and second surfaces (24a, 26a) may be serrated.

The latching member (4) has a closed and an open position. In the particular embodiment illustrated in Figure 3, the latching member is disposed in the closed position. In this position, the clamping element (20) blocks the rotational movement of the rolling element (8) in the first rotational direction (12), the clamping element being clamped to a component of the rolling element (8) ( 9) A first clamping position between the first stop element (24). Thereby the rotational movement of the rolling element (8) is blocked in the first direction of rotation (12). The component (9) of the take-up element (8) is disposed at one of the axial ends of the take-up element (8). In the component (9) of the rolled up component (8), the strap (2) is not rolled up. The strap (2) is rolled up at the center of the take-up element (8) and can be seen from the axial direction.

The outer surface (11) of the component (9) of the take-up element (8) has an outer zigzag shape. In the illustrated embodiment, the component (9) of the take-up element (8) is gear shaped. However, the component (9) of the rolled up element (8) may also be elliptical or oval.

In the illustrated embodiment, the clamping element (20) is a roller-shaped element having at least one side of an elastomeric material. The elastic material can be, for example, rubber. Since the clamping member (20) has a resilient side, the material of the clamping member (20) can be pressed against the outer serration of the outer surface (11), and when clamped in the first clamping position, the first is pressed to the serrated shape. Surface (24a). In this case, on the one hand, a non-positive and positive meshing exists between the clamping element (20) and the component (9) of the rolling element (8), and on the other hand, is present in the clamping element ( 20) between the serrated first surface (24a). A non-positively engaged engagement element is joined to each other by friction between the elements. A positively engaged joint is formed to engage one another due to the shape of the elements.

The first surface (24a) of the first stop element (24) is designed and arranged such that the first surface (24a) of the first stop element (24) and the at least one part of the roll-up element (8) The distance between the outer surfaces (11) of (9) becomes smaller in the first rotational direction (12). This means that as long as the rolling element (8) is further rotated in the first direction of rotation, the clamping element (20) is a part (9) of the rolling element (8) and the first stopping element (24) The first surface (24a) of the first surface (24a) is strongly clamped.

Figure 4 illustrates the scrolling device (6) of Figure 3 with the latching member (4) disposed in the open position. In order to move the blocking member (4) from the closed position to the open position, the handle element (28) can be pressed and the transmission housing (30) of the blocking member (4) reliably supports the rolling device (6) The housing (36) moves. When the latching member (4) is moved from the closed position illustrated in Figure 3 to the open position illustrated in Figure 4, the drive housing (30) of the latching member (4) is reversible against the return applied by the second return member (32) The force moves against the support housing (36) of the scrolling device (6). The retaining element (22) is rotatable together with the transmission housing (30), the retaining element being coupled to the transmission housing (30) through the pivot (18). Here, the clamping element (20) is moved via the winding shaft (16) together with the holding element (22). The clamping element (20) is pressed against the first surface (24a) of the first stop element (24) and directed to the intermediate position illustrated in Figure 4. When moved to the intermediate position, the clamping element (20) is moved away from one of the components (9) of the rolling element (8).

In the intermediate position, the clamping element (20) does not contact the rolling element or a component (9) of the winding element such that the rotational movement of the rolling element (8) is not blocked and the rolling element is The first and the second rotational directions (12, 14) rotate. Therefore, as the clamping member (20) is in the intermediate position, the strap can be pulled or unwound from the rolling member by pulling the strap (2) against the return torque of the first return member (2) ). To not pull the strap (2), the strap (2) is wound around the take-up element due to the return moment of the first return member.

By no longer pressing the handle element (28), the latching member (4) can be returned to the closed position. Since the return force is applied by the second return element (32), the latching member (4) returns to the closed position as long as the pressure above the handle element (28) is removed. Here, the clamping element (20) can be pressed against a component (9) of the rolling element (8).

When the rolling element (8) is rotated in the first direction of rotation (12), the clamping element (20) pressed against one of the parts (9) of the rolling element (8) will be associated with the winding element (8) Moving in the first direction of rotation (12) and being pressed against the first stop element (24) and clamped in the first clamped position. Thereby, the rotation of the rolling element (8) in the first direction of rotation (12) is blocked.

Alternatively, when the blocking member (4) is moved to the closed position, the clamping element (20) pressed against one of the components (9) of the rolling element (8) is along the second direction of rotation (14) Moving, when the rolling element (8) is rotated in the second direction of rotation (14) and pressed against the second stopping element (26), thereby being clamped to a part of the rolling element (8) ( 9) A second clamping position between the second stop element (26).

The structure of the second stop element (26) is similar to the structure of the first stop element (24). The second stop element also includes a second surface (26a). As exemplified above, the second surface (26a) may also be serrated. The second surface (26a) of the second stop element (26) is also constructed and arranged such that the second surface (26a) of the second stop element (26) and the rolled element (8) are at least The distance between the outer surfaces (11) of a component (9) is reduced in the second direction of rotation (14). Thus, when the rolling element (8) is further rotated in the second direction of rotation (14), the second clamping element (20) is also clamped more strongly and is thus even more strongly blocked. When the clamping element (20) is disposed in a second clamping position between a component (9) of the rolling element (8) and the second stopping element (26), blocking the rolling element in the second rotational direction (14) Rotational motion, and the strap (2) cannot be pulled out from the rolling up element (8).

When the strap (2) is pulled, a torque acts on the rolling element (8) in the second direction of rotation (14). When the strap (2) is no longer pulled out and the latching member (4) is continuously in the closed position, the return moment of the first return member acts on the take-up element (8). Thereby, the take-up element (8) is again rotated in the first rotational direction (12). Since the blocking member (4) is held in the closed position, the clamping member is still pressed against a component (9) of the rolling element (8), together with the rolling element (8) in the first direction of rotation ( 12) moving and pressing against the first surface (24a) of the first stop element (24), thereby also blocking the rotational movement of the rolling element (8) in the first direction of rotation (12), The strap (2) is no longer rolled up.

As exemplified in the example of Fig. 5, if the clamping element (20) is in the second clamping position and the blocking member (4) is moved from the closed position to the open position, the clamping element (20) is again moved to the intermediate position, as shown in the figure. 4 is shown. Here, the second surface (26a) of the second stop element (26) is also used as a guide element for the clamping element (20).
