It is an object of the present invention to provide a microphone holder which enables a more flexible use of a microphone.

This problem is solved by a microphone holder according to claim 1.

Thus, a microphone holder with a multi-component swivel joint is provided. The joint has a first, second, and third component, with the first and second components being rotatable relative to each other, and the second and third components being rotatable relative to each other. The microphone holder has a first end for mounting on a stand and a second end to which a microphone can be attached. A swivel joint is provided between the first and second ends, allowing either end to pivot. This joint enables a swiveling motion. At the second end, a rotational movement can be achieved with the longitudinal axis of the microphone holder as the axis of rotation. This rotational movement allows for rotation between a holder, which is pivotally coupled to the first end, and an adjustment ring to which the microphone can be coupled.

Furthermore, a clamping piece is provided which can be inserted into the first end of the first component and screwed securely to the third component to prevent rotation. The second component and one end of the third component can be inserted into the second end of the first component.

The multi-component swivel joint allows for rotations of >180° and, in particular, >360°. Since the swivel joint has two independent rotational movements, each with its own stop, the total rotational movement is the sum of the two rotational movements, thus enabling rotations of >360°.

From one perspective, the first component represents an adjusting ring, the second component a stop ring, and the third component a holder.

According to one aspect, actuation of the first component leads to a rotation between the first and second components until a stop lug of the first component contacts the first stop lug of the second component. This is the second rotational movement. A further rotation of the first component leads to a rotation between the second and third components until a second stop lug of the second component contacts the stop lug of the third component. This is the first rotational movement.

According to one aspect, a spring is provided between the second and first components to generate a holding torque.

According to one aspect, the clamping piece and the second and third components can be fastened together using a screwdriver.

According to one aspect, the microphone holder has an adjustment ring, a stop ring, and a holder. The adjustment ring is rotatably coupled to one end of the holder via the stop ring. The holder has a stop lug to limit rotation. The stop ring has a first and second end, each with a first and second stop lug. The adjustment ring has a first and second end, with a stop lug at the second end that can interact with a stop lug of the stop ring to limit rotation. The second stop lug of the stop ring is positioned over the second end of the holder, so that the stop lug of the holder limits the rotation of the second stop lug of the stop ring. A rotation of, for example, 190° is possible between the holder and the second end of the stop ring. The first stop lug of the stop ring at the first end of the stop ring interacts with the second end of the holder. adjusting ring together, so that the stop lug of the adjusting ring interacts with the first stop lug of the stop ring to allow a rotation of, for example, a maximum of 190°.

Optionally, a wave spring can be provided between the stop ring and a second end of the adjusting ring.

Further embodiments of the invention are the subject of the dependent claims.

1 Figure 1 shows a schematic representation of a microphone holder with a stand and a microphone. The microphone holder 100 has a longitudinal axis 103, a first end 101, a second end 102, and a swivel axis 104. A stand 200 can be attached to the first end 101. A microphone 300 can be attached to the second end 102. The swivel axis 104 allows the microphone holder to swivel relative to its first and second ends 101 and 102. The first end 101 has a retaining element 105, which is coupled to a holder 130 via the swivel axis 104. Furthermore, a rotational movement with the longitudinal axis 103 as the axis of rotation can be performed at the second end 102 by means of a multi-component swivel joint 106.

2A shows an exploded view of a microphone holder, and 2B Figure 1 shows a schematic sectional view of the microphone holder. The microphone holder 100 has a multi-component swivel joint 106 with an adjustment ring 110, a stop ring 120, and a holder 130, which can be pivotally coupled to a retaining element 105. The adjustment ring 110 has a first and second end 111, 112. The stop ring 120 has a first and second end 121, 122. The first end 121 of the stop ring 120 is coupled to the second end 112 of the adjustment ring 110. The holder has a first end 131 and a second end 132. The holder 130 can be pivotally coupled to the retaining element 105 via its first end 131. The second end 132 of the holder 130 is rotatably coupled to a second end 122 of the stop ring 120. The second end 112 of the adjusting ring 110 and the first end 121 of the stop ring 120 are also rotatably coupled to each other.

3 Figure 1 shows a schematic perspective view of a holder and a stop ring. The stop ring 120 has a first end 121 and a second, opposite end 122. A bore 123 may also be provided in the center. A first stop lug 124, for example in the form of a partially circumferential projection, is provided at the first end 121. A second stop lug 125 may be provided at the second end 122. This stop lug 125 may be designed as a partially circumferential projection. The first and second projections 124, 125 serve as the first and second stop ring stop lugs.

The second end 132 of the holder 130 has a recess 133 that circumferentially extends at least partially and a holder stop lug 134. The second end 122 of the stop ring 120 is positioned on the second end 132 of the holder 130 such that the stop ring 120 is at least partially rotatable. The second projection 125 can be positioned in the recess 133. The rotation of the stop ring 120 is limited by the holder stop lug 134. When the stop ring 120 rotates, the projection 125 comes into contact with the holder stop lug 134 and thus limits the rotational movement. Optionally, a rotational movement of, for example, 190° between the stop ring and the second end 132 of the holder 130 is possible.

4 Figure 1 shows two schematic sectional views of an adjusting ring and a stop ring. An adjusting ring nose 115 is provided at the second end 112 of the adjusting ring 110, which is arranged with the first projection 124 on the first side 121 of the stop ring to limit rotation.

5 Figure 1 shows a schematic sectional view of the microphone holder. At the second end 132 of the holder 130, a second end 122 of the stop ring 120 with a second projection 125 is provided. The projection 125 can engage in the holder's stop lug 134 to limit rotation. A wave spring 150 can be provided between the first side 121 of the stop ring 120 and the second side 112 of the adjustment ring 110.

A first rotation range is achieved between the holder 130 and a stop ring 120. A second rotation range is achieved between the stop ring and the adjusting ring. The maximum rotation between the holder and the adjusting ring is thus the sum of the first and second rotation ranges. Therefore, a rotation of more than 360° is possible. For this to be achievable, the first and second rotation ranges simply need to be designed accordingly, i.e., have a rotation range of > 180°.

Between the holder 130 and the stop ring 120, two end positions are provided to limit the rotation. Between the stop ring 120 and the adjusting ring 110, two end positions are also provided to limit the rotational movement. The total rotational movement between the holder 130 and the adjusting ring 110 is then the sum of the possible rotational movements between the holder 130 and the stop ring 120 and between the stop ring 120 and the adjusting ring 110.

The interaction between the holder, the stop ring, and the adjusting ring defines the end positions of the rotation. At its second end 132, the holder 130 has a holder stop lug 134. This holder stop lug 134 defines the possible end positions of the rotation between the stop ring 120 and the holder 130. The stop ring 120 has a first and second stop lug 124, 125, which are designed, for example, as partially circumferential projections. The second stop lug 125 can then interact with the holder stop lug 134 to limit a rotational movement. Depending on the width of the holder stop lug 134 and the length of the projection 125 or the stop lug, an angular range of rotation between the stop ring 120 and the holder 130 can be provided. Optionally, this angular range can be 190°. In other words, the stop ring 120 can be rotated 180° relative to the second end 132 of the holder 130.

A second rotational movement is enabled by the interaction between the first side 121 of the stop ring 120 and the second side 112 of the adjusting ring 110. A first stop lug, for example in the form of a partially circumferential projection 124, is provided on the first side 121 of the stop ring 120. At the second end 112, the adjusting ring 110 can have an adjusting ring stop lug 115. The adjusting ring stop lug 115 can interact with the first stop lug 124 on the first side 121 of the stop ring to limit rotation between the adjusting ring 110 and the stop ring 120. Optionally, this angular range can be, for example, 190°. Through the interaction between the first stop lug 124 and the adjusting ring stop lug 115, a relative movement of, for example, 190° can be achieved. When the adjusting ring 110 is rotated, a rotation occurs between the adjusting ring 110 and the stop ring 120, or a rotation occurs between the holder 130 and the stop ring 120. This rotation continues until the holder stop lug 134 makes contact with the second stop lug 125. Further relative rotation between the holder 130 and the stop ring 120 is then no longer possible. With a further rotation of the adjusting ring, a rotation then occurs between the first end 121 of the stop ring 120 and the second end 112 of the adjusting ring 110, until the first stop lug 124 makes contact with the adjusting ring stop lug 115. This then limits further rotation, so that only rotation in the opposite direction is possible.

The total relative rotational movement of the microphone holder consists of the second rotational movement between the holder 130 and the stop ring 120, as well as the first rotational movement between the stop ring 120 and the adjustment ring 110.

To provide a holding torque between the adjusting ring 110 and the holder 130, a pre-tensioned wave spring 150 can be provided between the stop ring 120 and the adjusting ring 110. The spring force of the wave spring 150 presses the stop ring 120 onto the holder 130 on one side and pushes the stop ring 120 and the holder apart on the other. This separation can be blocked by the clamping unit 140, which is screwed into the holder 130 in a rotationally secure manner by the adjusting ring 110, the stop ring 120, and the wave spring 150. The outer collars of the clamping unit press against the inner collars of the adjusting ring, creating a friction surface.

Since the clamping unit 140 is screwed to the holder 130 in a rotationally secure manner, it moves relative to the adjusting ring 110, thereby generating a frictional force at the friction surface where the two collars are in contact. This frictional force is responsible for the majority of the holder torque during the relative movement between the adjusting ring and the holder, as the wave spring 150 and the stop ring 120, which also undergo relative movement, can optionally be lubricated.

The clamping piece 140 can be inserted into the first end 111 of the adjusting ring 110.

The clamping piece 140 has a first and second end 141, 142, the second end being insertable into the first end 111 of the adjusting ring. At least one bore 143 is provided at the second end 142.

Furthermore, the holder 130 has at least one first bore 137. A wave spring 150 and the stop ring 120 are inserted into the second end 112 of the adjusting ring 110. Subsequently, the second end 132 of the holder 130 is also inserted into the second end 112 of the adjusting ring 110. The clamping piece 140, with its first and second ends 141, 142, and at least one bore 143, is inserted from the first end 111. Screws 200 can be used to fasten the clamping piece 140 to its second end 132. These screws are guided through the bores 173 at the second end 132 of the holder and through the bores 143 in the clamping piece 140 and can be tightened accordingly. This provides a microphone holder that allows for a rotational movement of > 360°.
