tripod

The invention relates to a stand ordered from a tube which forms the column of the stand with which tube at least three feet are connected, each of which consists of two articulated There are interconnected rods, of which the free ends with bent rod ends are articulated in provided on the tube Joint parts are attached in such a way that for all misses the lower rods after the lower joint part and the upper Rods are directed towards the upper joint part, of which Joint parts of the upper slidably and lockably attached to the tube. Such a tripod is from the German Utility model /I.887.062 known. This well-known tripod has a column, which consists of one piece and the feet can by sliding the upper part of the joint over the entire length of the column can be folded along the column so that the tripod can be picked up or shipped. In order to be able to fold the feet along the column, the upper part of the joint must be can be moved over a very large length. ,

The purpose of the invention is now to create a tripod which takes up much less space when it is to be sent or stored. According to the invention is now also the The lower hinge part is slidable and the column consists of a number of parts that can be plugged into one another. By dividing the column into three pieces of pipe, for example, which are used to assemble the column into one another can be plugged in and can be pulled apart for picking up or shipping, becomes the length of the column

to pick up or send, significantly reduced while nevertheless the lower joint part can be pushed through via the lower tube of the column, the possibility of folding your feet along the column is maintained.

In the case of the known tripod, they are articulated with one another connected rods of the feet in the position in which they are folded along the column, in mutual extension what was a result of the fixed attachment of the lower hinge part to the lower end of the column. By virtue of the fact that according to the invention Now both joint parts can be moved, both the upper and the lower joint part can be used to fold the feet be moved towards the upper end of the lower drill bit, causing the feet to collapse Extend position along the lower pipe section.

The upper joint part can be operated by hand in the same way as with the known tripod, by means of spring pressure be provided on the pipe engaging locking device, so that the displaceable upper hinge part in any desired position can be fixed on the column locked upper hinge part tend to slide towards the lower end of the column, where it is by means of a Stop can be prevented from pushing off the column.

To ensure that the column offers sufficient stability in the sense that pivoting movements around the axis of the column can be avoided, according to the invention, the lower pipe piece near the lower end over part of its length with one outside of the pipe surface protruding in the longitudinal direction running guide part for the lower joint part be provided, of which guide part the upper end forms a stop for the upper joint part.; This is the lower joint part in the working position no turning movements, in can perform with respect to the column. Also with this Guide part achieved that the ^ displacement of the-lower

Joint part over the column takes place a little more difficult, which on the one hand promotes stability and on the other hand supports the folding of the feet because that? pushes of the lower joint part is easier as soon as this joint part has arrived on that part of the column is where the guide part no longer exists. A very simple construction for the guide part becomes obtained according to the invention if this consists of a wire, which with bent ends in holes of the tube is attached. The guide part consists, then, of one wire extending longitudinally over the outer surface of the lower pipe section, and the lower hinge part is Of course, provided with a recess in the wall of the opening surrounding the column, which space for this.m wire offers. Tubes for tripods are very often through at the bottom closed a stopper. According to the invention, this plug can now be replaced by this bent wire end be held and further with, an outside of the_ Rohres excellent flange be provided, which the stop for the lower joint part.

In the known tripod, the lower joint part is made of plastic and: according to the invention, this joint part can have lips which are cut at an angle at the edge of the opening for the pipe ensure that when the I-joint part is moved over the tube is aligned downward with respect to the hinge part, on the guide part.

The invention will now be explained further with reference to the drawings.

Fig. 1 shows a view of the?, Tripod according to the invention.

Figure 2 is a view of the tripod of Figure 1 with the top mounting button removed. Figure 3 is a "": cross-section of the lower end of the column. Figure 4 is a cross-section of the column at "the site of the bath of the guide wire. . ^ - ~ ^{; r :;} "I Fig. 5 is a bottom view of a fine part of the lower joint part. ■" ■■ .. ■

FIG. 6 is a cross-section on line VI-YI of FIG Fig. 5.

In the tripod according to FIG. 1, the hall consists of the drilling parts 1, 2 and 3, which have been inserted into one another in a known manner and are locked in this position by means of a button 5 pressed outward by a spring 4. At the upper end of the tube 1 there is an organ 6 for attachment, for example a dryer hood.
On the lower pipe section 3 there are two joint parts 7 and 8 which can be displaced out of the pipe 3 and articulately encompass the ends of the rods 9 and 1o, the rods forming the feet and being articulated to one another at 11. The outer end of the rod 1o is bent over in the shape of an eye, in which the rod 9, which is bent in the manner of a hairpin, has been attached.

The hinge part 7 consists in a known manner of two e.g. parts connected to one another by means of screws or rents, which are designed in such a way that the bent ends of the Rods 9 can be included between these parts.

12 is a locking lever, which is inclined by the spring 13 in Position is pressed with respect to the pipe 3 and thereby clamps the joint part 7 on the pipe.

Fig. 3 shows the lower end of the tube 3. As can be seen from this figure, there is the lower joint part also of two parts 14 and 15 connected to one another by means of screws, between which the bent ends the rods 1o are articulated. In the end of the pipe there is a plug 16 with a flange 17 which protrudes radially outside the outer surface of the pipe 3 and downwards a stop for the lower joint part forms. A straight wire 18 is arranged along the outside of the tube over part of the length of the tube, which protrudes with a double bent end 19 into a hole in the tube and into a recess.

of the plug 16, whereby this also in its place is being held. As can be seen from Figures 1 and 4,

this wire 18 runs up part of the length of the tube and is at a higher point with the end has been pushed through an opening in the tube, the end also being bent over.

This wire 18 forms a guide for the lower joint part, which for this purpose has a suitable recess 21 is provided. Because the upper hinge part has such a recess does not have, the upper end of the wire 18 forms a stop for the upper joint part.

As can be seen from Figures 5 and 6, the lower joint part has a number of downwardly directed lips 22 in the lower part which, when displaced over the tube, align the joint part with respect to the guide wire in that the oblique edges of the lips provide for this that the joint part with one of the four grooves 21 in dif ¹ correct: ·: position is brought in relation to the wire.
m.

To collapse the upper hinge part is first moved in the direction of the upper end of the tube 3 undManach the Lower joint part moved by hand in the same direction, with rods 9 and 1o folding along the tube. The pipe sections 1 and 2 can then be removed, so that a Package low is possible.
