[0028] Fig. 1 Figure 10 shows an acoustic warning device 10 comprising a first housing element 1, which includes at least one receiving means for attaching a fastening element 6 for mounting on a body or device, and a second housing element 2. The first housing element 1 is rotatable relative to the first housing element 2. A spring element 3 is arranged between the first housing element 1 and the second housing element 2. The spring element 3 includes at least one stop element 4, 5, which, in the installed state, engages with a noise-generating element 21 arranged in the second housing element 2 (see Figure 1). Fig. 5a ) is in contact, so that when the second housing element 2 is rotated, a noise can be generated by the contact between the noise-generating element 21 and the stop element 4, 5. According to the present embodiment, the fastening element 6 is designed as a wristband.

[0029] According to the present embodiment, the spring element 3 includes at least two stop elements 4, 5. According to this embodiment, the two stop elements 4, 5 have the same distance with respect to the center point of the two axes of symmetry of the spring element 3.

[0030] Fig. 2 Figure 1 shows a detail of an embodiment of a spring element 3. According to the present embodiment, the spring element 3 is designed as a disc-shaped element comprising an outer ring element 33 and an inner ring element 34. The outer ring element 33 is connected to the inner ring element 34 via a first web element 35 and a second web element 36. The inner ring element 34 contains a first mounting opening 31 and a second mounting opening 32. In the installed state, the first and second mounting openings 31, 32 receive the first and second mounting elements 11, 12 of the first housing element 1; see in particular the following. Fig. 4a The spring element 3 is thus rigidly connected to the first housing element 1 in its installed state. In particular, the spring element 3 can be attached to the fastening elements 11, 12. The spring element 3 is stationary with respect to the second housing element 2, as it remains rigidly connected to the first housing element 1. However, the spring element 3 can be displaced axially along the fastening elements 11, 12. Therefore, the spring element 3 remains suspended, ensuring that the contact between the stop elements 4, 5 and the noise-generating element 21 is maintained.

[0031] Fig. 3a Figure 1 shows a detail of a stop element 4, 5 in a first view. According to this embodiment, the stop element 4, 5 is a rotationally symmetrical body comprising a conical first end section 41, a cylindrical middle section 43, and a second end section 42 shaped like a cylindrical pin. The second end section 42 is designed to be received in the corresponding first or second mounting opening 31, 32 of the spring element 3. The spring element may, in particular, contain a metal. The stop element may, in particular, contain a plastic, for example, POM.

[0032] Fig. 3b Figure 1 shows a detail of a stop element 4, 5 in a second view, in which the second end section 42, which is designed as a cylindrical pin, is more clearly visible.

[0033] Fig. 4a Figure 1 shows an interior view of the first housing element 1. According to the present embodiment, the spring element 3 is connected to the first housing element 1 by means of a first and second fastening element 11, 12. According to the present embodiment, the first and second fastening elements 11, 12 are each designed as a pin element. At least one of the first or second fastening elements 11, 12, or each of the first and second fastening elements 11, 12, engages in a corresponding fastening opening 31, 32 of the spring element 3.

[0034] In Fig. 4a The receiving device 14 for a fastening element 6 is also shown, which according to Fig. 1 is designed as a bracelet.

The central opening 17 serves to receive the connecting element 8, which is located in Fig. 1 As shown, according to the present embodiment, four rinsing openings 15 are arranged on the outer concentric circle and four rinsing openings 15 are arranged on the inner circle. The rinsing openings 15 can, in particular, be designed as kidney-shaped rinsing openings.

[0037] Fig. 5a Figure 1 shows an interior view of the second housing element 2. According to the present embodiment, the noise-generating element 21 has a profile 22 with wave-like projections, in particular a wave or tooth shape. According to the present embodiment, the noise-generating element 21 is arranged on the inside of the cover section 27. The wavelength and amplitude of the waveform can be changed. Thus, the noise frequency of the warning device can be adapted to the desired application.

[0038] According to one embodiment, the wave-shaped element is formed as a molded plastic part. The use of POM as the plastic has proven particularly advantageous. POM has self-lubricating properties, which increases the service life of the noise-generating element. Alternatively, other materials, such as metals, can also be used. In particular, the nature of the generated noise can be altered by selecting the appropriate material, especially its pitch and / or volume.

[0039] The noise-generating element 21 is ring-shaped. In particular, the noise-generating element can be configured as a circular ring lying on a circle whose center lies on the central axis of the second housing element 21. The housing element 21 contains a central bore 23, which is used to receive the noise-generating element. Fig. 1 The connecting element 8 shown serves this purpose. The central bore 23 can in particular contain a thread 24.

The optical markings may also include luminous or reflective surfaces to increase visibility in the dark.

[0041] The second housing element 2 includes a rotating aid 26, which can be formed, in particular, by the wall section. The rotating aid includes a plurality of bearing surfaces 29, which can be arranged on the circumference of the second housing element 2, in particular in the wall section 28. According to the present embodiment, the bearing surfaces 29 form a polygon, in particular a heptagon. An advantage of using a polygon, for example a heptagon, is that a mounting element (not shown) can be placed on the second housing element 2. Such a mounting element can, for example, contain a compass.

[0042] Fig. 6a Figure 1 shows a partial exploded view of an acoustic warning device 100 according to a second embodiment.

The rotation aid 116 can include a plurality of contact surfaces that can be arranged on the circumference of the first housing element 101. As in the first embodiment, the contact surfaces can form a polygon, in particular a heptagon, which is not shown in the drawing. An advantage of using a polygon, for example a heptagon, is that a mounting element (not shown) can be placed on the first housing element 101. Such a mounting element can, for example, include a compass. Alternatively, the rotation aid can have a profile. The profile can, for example, comprise a plurality of knobs, grooves, or ribs that can be arranged on the outer surface of the first housing element 101.

[0045] According to this embodiment, at least one rinsing opening can be arranged in the lid section, which is not shown in the drawing.

Each of the pin elements can be individually connected to the cover section 127. Therefore, each of the pin elements can be individually replaced when signs of wear become visible or audible. Furthermore, pin elements made of different materials can be used. This allows the pitch of the generated noise to be varied.

[0049] The number of pen elements can also be varied to change the frequency of the sound.

[0050] According to this embodiment, the first housing element 101 is constructed in two parts and comprises a first housing element 111 and a second housing element 112.

The rotation aid 216 can include a plurality of contact surfaces that can be arranged on the circumference of the first housing element 201. As in the first embodiment, the contact surfaces can form a polygon, in particular a heptagon, which is not shown in the drawing. An advantage of using a polygon, for example a heptagon, is that a mounting element (not shown) can be placed on the first housing element 201. Such a mounting element can, for example, include a compass. Alternatively, the rotation aid can have a profile. The profile can, for example, comprise a plurality of knobs, grooves, or ribs that can be arranged on the outer surface of the first housing element 201.
