Durable gooseneck

The invention relates to a gooseneck in which each link can be clamped and therefore does not move even under load.

Goosenecks on microphone stands or lamp holders are well known. However, in these areas of use, the ability to be secured is not so important. Therefore, these goosenecks are usually only made from interlocking pieces of pipe, with no clamping option.

In the technical field, it is advantageous to hold heavier devices such as computers, keyboards, telephones, etc. securely in an individual structure and arrangement. Sometimes, for example, the installation in cars _, trucks or buses is very difficult. From the fastening point to the most convenient location, corners, radii and twists are necessary. All of this should be possible with the necessary load-bearing capacity, which also prevents buckling and misalignment in the event of vibrations such as those that occur in vehicles. The resilient gooseneck can be used to hold tools, vices and devices in industrial production.

Likewise, during medical treatment, devices and treatment instruments sometimes need to be kept at the correct eye level or within reach.

There are still many possible applications in which very universal adjustability and load-bearing capacity are required, from fastening to the place of use.

It is very advantageous that there is a continuous free space (7) in the gooseneck through which cables or hoses for liquid, gas or air can be passed. It is also important that the gooseneck can be shortened or lengthened by simply removing or inserting links.

The above-mentioned properties are achieved according to the invention by means of link pieces (1 and 6) which have spherical ends, which are mounted in a slotted housing (2 and 3). This slotted housing consists of two half shells (2 and 3) with recesses adapted to the spherical link pieces (1 and 6). The locking screw (4) enables the link pieces (1 and 6) to be clamped in place.

To ensure that the gooseneck remains stable even after loosening the locking screws (4), a spring washer (5) (wave washer) or a compression spring can be mounted under the screw head.

The end pieces of the gooseneck each have a screw (8) or pin (9) on one side. Like the housings (2 and 3) and link pieces (1 and 6), these can have holes (7) for passing through cables or hoses. After loosening the locking screws (4), the link pieces (1 and 6) can be swiveled and tilted in the spherical radius.

Shown are: Figure 1 a clampable gooseneck with spherical joints on both sides (1) and a two-part housing (2 and 3), locking screws (4) with a corrugated washer (5). One end piece is drawn inclined.

Figure 2 shows a clampable gooseneck as described in Figure 1, but with spherical links on only one side (6).

Claims (1)

Protection claims Load-bearing gooseneck, characterized in that spherical link pieces (1 and 6) are mounted in a two-part housing (2 and 3) so that they can rotate and tilt and can be clamped with a locking screw (4). Load-bearing gooseneck according to claim 1, characterized in that the link pieces (6) are spherical on only one side and the other side is designed as a pin or screw. Load-bearing gooseneck according to claims 1 and 2, characterized in that the pins (9) and screws (8), as well as the link pieces (1 and 6) and housing (2 and 3) have continuous cavities (7) through which cables or hoses can be passed. Load-bearing gooseneck according to claims 1 to 3, characterized in that the two-part housings (2 and 3) are spring-loaded relative to one another, so that when the locking screws (4) are loosened there is still a pre-tension that prevents the unloaded gooseneck from collapsing.
