Description

The subject of the invention is a clamping device wheels with a longitudinally sliding pin may a conical recess on its lateral surface nej, which connects two elements separately profile, which device further comprises from a screw led in a threaded sleeve, which is situated eccentric to of said recess and works with the pin not to pull the two elements together ne as well as from the insertion core sliding in one of the connected elements and immobilized.

It is known to join frame elements and / or together walls consisting of profile elements by means of devices having a lengthwise slide not pins. Such a pin is guided in one of the connected elements and it has on one finally the T-shaped head that goes into appropriate cut in the second element. Mozli¬ the value of the longitudinal movement of the pin is obtained due to the conically terminated common screw works with a conical hole on the pin, cannon thus pouring the pressure wedge.

In these known clamping devices, force it is transferred from the head of the bolt through the bolt and acts on an opening made in one of the joints profile elements. With multiple loosening and retightening the bolt then I seriously damage such a hole, especially 2 when such an element is made of metal light.

Manipulation is also difficult and time-consuming such devices because you need to hold Wac srube as well as the inserted core and pin when making a call.

The task of the invention is to create a device clamp of said eliminating type the above-mentioned disadvantages and inconveniences that would enable simple and quick connection of two elements ments and which also after repeated loosening and re-pressing would not cause damage damaging any part of the connected elements.

This task has been solved according to the invention This way, with the pin, the threaded bushing the screw and the screw are placed in the insertion core and for holding said core in one of the joined elements appropriate measures have been taken.

The subject of the invention is illustrated in, for example, the embodiment in the drawing in which fig. 1 shows the device according to the invention in a row perspective view in the unfolded state and one of the joined elements, fig. 2 - the same the element combined as in Fig. 1 with the inserted core shown in a side view, and Fig. 3 is the same the system of central heating in Fig. 2, along the line III- III, the second being additionally shown here combined element.

Fig. 1 shows the first of the profile elements 94 20094 200 3 4 menta 6 in the folding frame made of many such elements, in which it is the menu can be slidably positioned and lifted Movable insert core 2. Insert core 2 has holes 8, 9 to accommodate the pin 1, compression spring 4 and threaded sleeve 3 with screw 5.

The profile element 6 preferably has a cross-section rectangular with guides projecting inwards with 11 threads for guiding the core to be inserted 2.

The profile element is furthermore provided with hole 12, which cooperates with groove 13 made on the threaded sleeve 3.

Pin 1 rotates freely in hole 8 i | wetawiigHCglf ^ ggTla 2 and may also shift nalW ^ Meruiwu ^ lzdluznym in this hole, at [what between the inner end of this pin tnia and ¦¦Ko.Ój ^ B ^ j.woW 8 is placed compressed lsOT ^ jslJiay JUfLjeb and the pin is formed Lluuiiu 1 WlfllUUkl By locking with its profile T-piece in the slot 16 of the second profile piece ment 7.

Moreover, in pin 1 there is a conical one recess 17, into the interior of which a cone protrudes end 18 of bolt 5. Bolt 5 is guided in the threaded bush 3, which for its part it is placed in the hole 9 of the insertion core 2. In the threaded bushing 3 there is a transverse hole 10 to accommodate the pin 1.

When joining both profile elements 6, 7 first the threaded bush 3 is inserted into the hole 9 insertion core 2.

The core 2 is then inserted together with the thread The important sleeve 3 is inserted into the provided for him, the space inside the first profile element 6. Now the threaded bushing 3 is displaced in the opening 9 towards the axis so that the groove 13 fits into the hole 12 of this profile element 6, thereby being inserted core 2 is run in the profile element menu 6. Now, in turn, the compression is inserted spring 4 and pin 1, which is threaded the sleeve 3 is rotated by means of a transverse naut cut 19 so that its transverse hole 10 covers match with hole 8 in insertion core 2.

Now screw the screw 5 into the threaded bushing on and so far until its conical ending 18 will be adjacent to the conical wall you choose 17. The pin 1 must be pressed in the hand against the action of the spring 4 so as to let it fly The ba 5 entered the conical cavity 17. T-shaped head 14 of the pin 1 now protrudes from the hole 8 like this can be seen in Fig. 2.

Finally, it follows the first element profile, the second profile element 7 in this manner make sure that the T-head 14 of the pin 1 goes into position longitudinal cut 16 and hooked into it.

The core 2 to be inserted is on its face side facing the second profile element of the line 7 has a rib 20 which fits in between long cut 16 of this profile element 7, prevent this element from turning.

By tightening the bolts 5, tapered ends 18 of this bolt presses against the conical surface the recess 17 is therefore axial displacement of pin 1 against the action of the spring Tines 4 and both profile elements remain to each other tight.
