Abstract
Description
Technical field
[0001] The invention relates to a device for the detachable fastening of a holder, in particular a beverage holder or a storage device, to a tubular support element, for example a music stand, microphone stand or instrument stand. State of the art
[0002] Common mounting options for music stands are typically attached using screw clamps, clamps, or bolted tension devices. These have several disadvantages. In particular, tools are often required, assembly is relatively time-consuming, and damage to the surface of the support element can occur. Furthermore, unwanted play often develops, causing the mount to wobble. Object of the invention
[0003] The invention is therefore based on the objective of providing a device that enables simple, tool-free, secure and backlash-free attachment of a holder to a tubular support element without damaging it. Solution
[0004] This problem is solved by a device having the features of claim 1.
[0005] The device comprises a holder body with a receiving area for receiving a tubular support element and a clamping wedge that can be inserted axially into a slot in the holder body.
[0006] By inserting the clamping wedge, two opposing clamping surfaces are pressed radially against the support element. This creates a play-free fixation of the holder body to the support element.
[0007] The clamping wedge preferably has a wedge angle of approximately 4°, thereby achieving a self-locking clamping effect.
[0008] Furthermore, an elastic element can be provided to support the clamping effect and prevent slippage. This elastic element can be made of TPU in particular.
[0009] The clamping wedge can be connected to the holder body via a flexible connecting element, such as a cord, to prevent loss of the clamping wedge. Designs
[0010] The holder body can be designed as a drink holder with a base.
[0011] In a preferred embodiment, a lateral slot is provided which allows the insertion of containers with handles.
[0012] Alternatively, the holder body can also be designed as a storage space for mobile phones or glasses.
[0013] The device can be designed for pipe diameters of approximately 15 mm, 20 mm, 25 mm or 30 mm.
[0014] The device is preferably designed for a load of up to approximately 2 kg.
Claims
[1] Device for detachably fastening a holder to a tubular support element, comprising a holding body with a receiving area for receiving the support element and a clamping wedge which can be inserted axially into a guide of the holding body, wherein by inserting the clamping wedge clamping surfaces are pressed against the support element and thereby the holding body is fixed. [2] Device according to claim 1, wherein the clamping wedge has a wedge angle of about 4°. [3] Device according to claim 1 or 2, wherein an elastic spring element is provided. [4] Device according to claim 3, wherein the elastic element consists of TPU. [5] Device according to one of the preceding claims, wherein the clamping wedge can be inserted axially from below. [6] Device according to one of the preceding claims, wherein the clamping wedge is connected to the holding body via a flexible connecting element. [7] Device according to one of the preceding claims, suitable for pipe diameters from 15 mm to 30 mm. [8] Device according to one of the preceding claims, suitable for pipe diameters from 10 mm to 50 mm. [9] Device according to one of the preceding claims, wherein the holding body is designed as a drink holder. [10] Device according to claim 9, wherein a lateral slot is provided for receiving containers with handles. [11] Device according to any one of claims 1 to 8, wherein the holding body is designed as a storage place for mobile phones or glasses.
