The invention relates to mechanical engineering and can be used when creating new banana devices.

Known devices for podpruzhineny containing either a compression spring or a tension spring is usually described in the book Pearlova "fundamentals of design", M.: Mashinostroenie, 1977, page 155-208.

A significant drawback of both devices is that springing in such devices is only possible in one direction.

The objective of the invention is to provide such podpruzhineny, which is possible in two mutually opposite directions.

Not known for such construction or literary sources such podpruzhineny parts or components of machines.

The task is the fact that the combined spring includes a compression spring, on the edges which is worn round the cage with a diameter larger than the diameter of the spring and with the internal channel in the upper wall in the form similar to the form extreme wrap and coverage to two-thirds or three fourths of the circumference of the coil fixing holder on the circuit by any known method, and part of the upper wall except the inner channel has a lower vertical frame, set wider than the outer diameter of the spring and the height equal to the diameter of the wire of the spring, with the convex part of the channel prog is the CIO below the top wall, and on top of each clip rigidly and symmetrically in the center vertically attached flat blank with a height equal to the height of the washer, the washer is made of a round symmetrical with the Central groove of the same shape as the rest, and this groove they freely worn with the possibility of removal of the lugs with fixing by means of the screw with a conical head, which is screwed in a threaded hole made in the center of the focus, and the washer coaxially with the specified hole is made of a smooth hole is larger than the diameter of the screw and rassverlivat on the cone of the inlet under the screw head so that it is installed flush relative to the side surface of the washer to the ends of the washers from both ends rigidly or pivotally attached podrazumevaemye parts or sub-assemblies of the machine can move them in two mutually opposite directions.

New the essential features of the invention:

on the edges of the compression spring worn round clip with a diameter larger than the diameter of the spring and with the internal channel in the upper wall in the form similar to the form extreme wrap and coverage to two-thirds or three fourths of the circumference of the coil fixing holder on the circuit by any known method,

- part of the upper wall except the inner channel has a lower vertical frame, set wider than the outer diameter of the spring and the height is equal to di the meter wire spring, this convex part of the channel goes from the bottom to the top of the wall,

- top each clip rigidly and symmetrically in the center vertically attached flat blank with a height equal to the height of the washers

- washer is made of a round symmetrical with the Central groove of the same shape as the rest, and this groove they freely worn with the possibility of removal of the lugs with fixing by means of the screw with a conical head, which is screwed in a threaded hole made in the center of the focus,

in the washer coaxially with the above-mentioned hole is made of a smooth hole is larger than the diameter of the screw and rassverlivat on the cone of the inlet under the screw head so that it is installed flush relative to the side surface of the washer,

- to the ends of the washers on both sides rigidly or pivotally attached podrazumevaemye parts or sub-assemblies of the machine can be moved in two mutually opposite directions.

These new significant features in conjunction with the known necessary and sufficient to achieve a technical result, in all cases, to which the requested amount of legal protection.

The technical result is achieved due to the fact that:

on the edges of the spring compression wear clip with an internal channel in the top wall of the locking clip any known way to d the th possibility of further details to influence the spring in two mutually opposite directions,

- execution on the upper wall clips flat lugs which are provided with washers with a corresponding groove in the center, with the subsequent fastening washers on the magazines as time and creates all conditions for compression or tension springs, as the clip is rigidly attached to a spring.

On 1 shows a front view of the combined spring, figure 2 is given a section a - a from figure 1, showing the relative positions of the stop and the washer.

Consider the device a combined spring. It includes the compression spring 1, the edges 2 which is worn round clip 3 with a diameter larger than the diameter of the spring 1 and the internal channel 4 in the top wall 5 in the form similar to the form at round 2, and covering two-thirds or three fourths of the circumference of the coil body with the fixing clip 3 on turn 2 by any known method. Part of the upper wall 5, except the inner channel 4 has a lower vertical frame 6 that is set wider than the outer diameter of the spring 1 and the height equal to the diameter of the wire of the spring 1. The convex part of channel 4 goes from the bottom to the top wall 5, and the top of each cage 3 is rigidly and symmetrically in the center vertically attached emphasis 7 height 8 washers, washers made of round symmetrical with the Central groove of the same shape as the rest 7. This groove they freely worn with the possibility of removal of the lugs 7 with fixation of p and the screw 9 with a conical head 10, which is screwed into the threaded hole 11 made in the center of the stop 7 and the washer 8 coaxially with the specified hole 11 is made of a smooth hole with a larger diameter screw 8 and rassverlivat on the cone of the inlet under the head 10 of the screw 9 so that it is installed flush relative to the side surface 12 of the washer 8, the ends of the washers from both ends rigidly or pivotally attached podrazumevaemye part 13 (shown dotted) or components of the machine can move them in two mutually opposite directions.

The work of the combined spring is that in the case of application of force along arrow B (one-sided or from both sides) spring has the ability to shrink down to a specified distance. In the case of efforts by the arrow In (one-sided or from both sides) spring also has the ability to be stretched by a specified amount. Thus, the combined spring may alternately or stretched or compressed by a specified amount, i.e. in two mutually opposite directions, which may not perform any compression spring or tension spring alone.
