is coupled so that the bolt of the connecting rod is guided in a transverse slot of the closer axis and the bolt of the universal joint just before the closed position on your IPedevteiler the closing spring to the system got.

The invention has the advantage that the movement of the wing before reaching the closed position see above is braked that the paddle is in the closed position stops without pendulum oscillations. ! In addition, works the closer according to the invention up to a few degrees of angle before the closed position without play, so dc £ ier closer in advantageous ./eise a'uch for einsoiti? opening doors used w -.-; rden can.

A closer shaft 4 is mounted in the housing 1, the cover-side surface of which protrudes beyond the cover 2. ¹ In the longitudinal center of the housing 1, a damping device is arranged ', on the cylinder 7 of which a closing spring 21 aitzt. This rests with its end facing away from the closer axis 4 on a shoulder of the damping device. Its other end is supported on a spring plate 23 which can be displaced on the damping cylinder 7.

A rocker arm 26 is attached to an attachment 24 * of the housing 1 articulated, which is articulated with a 'handlebar 27' is. The other end of this link 27 is pivotable about an axis 45 by means of a further rocker 43 out and carries a roller 46 with which it rests against the spring plate 23.

Below the cover 2, a cam disk 5 with an indentation is attached to the closer tube 4. The cam disk 5 is at the level of a roller 28 which is mounted on the end of the rocker arm 26 facing the closer tube 4. In the zero position of the closer, i.e. when the door is closed, the Rollt * 28 engages in the indentation of the cam disk 5, ^: ; which is approximately the porm of a. Has exenter disc. - '· ■

piece 52 with a pivot pin 53. A connecting rod 54 is mounted on this by means of an elongated hole 55, which is coupled to the closer axis 4 at its other end. Here it protrudes with its edge into a recess 56 of the closer axis 4 and is guided with a hinge pin 57 in two transverse, slightly curved slots 58 of the closer axis 4. The upper dog of the universal joint 53 of the universal joint is extended beyond the joint 52 and is provided with a recess here. With this, the pivot pin 53 rests in the 3-position of the closer against the collet 46 and, via this, against the Seder plate 23.

In the closer "according to the invention, the spring-loaded piston of the damping device, not shown, is coupled to the universal joint 52, 53 via a piston rod 17 and to the closer axis via the connecting rod 54, the G-pivot pin 57 being guided in the slots 58 Closing spring 21 acts shortly before the closed position via the J spring plate 23 and the sleeve 46 on the G-pivot pin 53.By this design of the door closer, the flow of force from the closing spring 21 via the closer axis 4 to the damping device is briefly closed and a few degrees before the closed position is reached attenuated the spring force of the closing spring when pivoting the! door leaf in expiry. This has the lolge that the wing is not abruptly pressed into the closed position Γ. This prevents for swing doors that the wing unit by destroying the Bewegungsernergie in oscillation.

Claims (1)

Claim: Closer especially for swing doors with a protruding from the housing in both directions rotatable closer axis, a closing spring, which has a handlebar and an im. Housing mounted Rocker engages the closer axis, and with a hydraulic damping device according to an additional patent (Patent application Y 17 197 Y / 68d), characterized in that the piston rod (17) of the piston of the damping device has a universal joint (52,53) and a connecting rod (54) is coupled to the closing shaft (4) in such a way that the bolt (57) of the connecting rod (54) is guided in a ^ uerschlitz (58) of the ücJaxießerachse (4) and the pin (53) of the Iu? euzge steering s shortly before the closed position comes to rest on the S "ederteller (23) of the closing spring (21).
