Height adjustable tripod

The invention relates to a height-adjustable stand with a stand base and a cantilever arm on which a device, for example a radiation lamp,

swiveling bsfestigbsrist. One such A stand is, for example, in DE-Gbm VB o7 i »93 as a holder for an irradiation lamp described.

Γϊεϊ the previously known tripod is the Be

Radiation lamp on a fork-shaped arm that can be pivoted about a horizontal axis attached. A gas pressure spring is on the one hand on the boom. *, On the other hand hinged to the stand column.

The tripod described in the utility model mentioned has numerous functional parts Defects. For example, if you consider the vertical distance of the tripod lamp in relation to the one to be irradiated Want to enlarge part of the body,

this must be done by swiveling up the boom. Through this pivoting movement the tripod lamp inevitably changes its direction of radiation at the same time, see above that they have to restore their original

Union radiation direction must also be schuienkt relative to the cantilever arm.

Rudolf! Yours, Friedberg 11/13/78

Furthermore, the radiation lamp approaches the stand column when it is swiveled up. The stand as a whole must therefore be drawn closer to the part of the body to be irradiated when you get the irradiation

The lamp swings up and - apart from the change in its height - in the same position should remain. This observation shows that to change the distance ES the irradiation lamDe of the one to be irradiated

Two parts of the body in addition to the swinging movement further settings have to be changed. This is quite inconvenient and inconvenient in practice makes it necessary to either do this for the irradiation selected place to be ver

leave, or call pine helper.

Another disadvantage of the previously known Stand is because the change in the distance of the irradiation device van der

Stand column when swiveling up the AisIeuetarrnps also changes in the torque which acts on the iiasriruckfedpr. That makes you precise weight compensation by means of the pressure spring impossible, ^ n that in practice

the cantilever arm relatively schwprqnngiq vurschijenkbar must be nelnqert so that the radiation lamp; stops in every set position and does not oelhsl-

actively lowers. .

The invention is based on the object a height-adjustable tripod of the entrance called type to develop, which unites the most comfortable possible adjustment of her held device allows.

This object is achieved according to the invention by the features specified in claim 1.

The advantages of the invention are first Line in that when height adjustment

of the device, for example the irradiation lamp, riin angular position of the device not negated. As a result, one needs Moving up the radiation lamp does not reduce or correct any other setting

to ioerden so that the handling of the training gymnastics Stntives extremely comfortable and is easy.

Another very important advantage of the non-rotatable guidance of the inner column in relation to the stand column is that tilting of the inner column in the Stand column with extremely simple means

can be avoided even with coarse tolerances of both components, since the angular position the points of contact between the two pillars "is always unchangeable.

In claim 2 is an advantageous feature

design of the invention characterized, the; unktioneli and manufacturing technology favorable is. This measure ensures that the weight of the device and the lever arm of the release arm exercised

Tilting moment leads to the inner column exclusively via two abutments supported on the stand column. Thereby are clearly defined conditions are given, PQ that tilting the inner column

can be unlocked in the stand column. For the production of the components dig tolerances are sufficient, since the inner column inevitably tilts so that on the one hand it m \ c the lower abutment on the stand column,

on the other hand, directly against the upper one Abutment of the stand column is applied.

Since the inner column telescopes out of the

Ulenn according to other forms of expression

Invention of the gas pressure spring with its cylinder part is supported in the inner column, only the plunger leads to the lower abutment Gas spring over. This means that there is enough space at this point to place a

Rolling body with sufficient for a low friction large diameter to be provided as the lower abutment.

Zuecknüißi rjertiieise is like another, advantageous embodiment of the invention the rolling element forming the lower abutment releasably attached to the inner column. This achieves that the gas pressure

spring after removing the roller pulled out of the inner column can.

It is beneficial if the tripod / foot has the shape a lying "U" and its two legs run parallel to the boom arm. That way you can't make one unnecessary Provide bulky tripod feet. Since the inner column cannot be rotated with the stand column is connected, the

Extension arm always between the two legs of the u-shaped stand base, so that by changing the setting of the device B, there is no risk of an overturning pin.

The advantage identified in claim Id

Adhesive Ausgestal tune of the invention is used to The tripod can be easily disassembled into space-saving parts for the purpose of shipping to be able to. It is important that the inner column is also in the stand column when shipping

remains and thereby held in this position is that the disc of the upper abutment protrudes into the slot in the inner column. The tripod according to the invention makes it possible despite

Rollers 5 are attached so that the tripod can be moved as a whole. A stand column 6 runs perpendicular to the level of the stand base 1. In this stand column 6 an inner column 7 is guided like a telescope, some of which is bent upwards and thus forms a cantilever arm Β. At the end of this cantilever arm B, an electrical irradiation device 9 is arranged in such a way that it can be pivoted about a horizontal axis 10 as well as about a vertical axis 11. The pivotability of the irradiation device 9 about its horizontal axis 1o can be blocked by means of a locking lever 12.
