Definitions

  • Connecting means operatively connects the slide means with the door to cause movement of the slide means between the positions thereofin response to movement of the door in its open and closed positions.
  • Biasing means permanently urges the slide means to rest position.
  • Adjusting means adjusts the biasing force exerted by the biasing means and includes a pair of parallel rods slidably extending from the interior of the housing beyond the other end of the housing to the exterior thereof, with the rods having first end portions located within and second end portions located without the housing.
  • An inner connecting member connects the first end portions and is associated with the biasing member, and an outer connecting member connects the outer end portions exteriorly of the other end ofthe housing.
  • the present invention relates generally to a device for closing doors and the like, and more particularly to a device of this type wherein a slide is movable longitudinally within a housing, being urged to a rest position by biasing means and being moved from its rest position in response to turning movement of the shaft with which it is associated and which in turn is connected with the door or other element to be closed by the device.
  • a more particular object of the invention is to provide such a device which is simple and compact in its construction but provides for reliable adjustment of the prestressing of the biasing means.
  • An additional object of the invention is to provide a device of the type under discussion wherein the adjustment of the biasing means can be readily carried out without any difficulties and without imparting to the biasing means any characteristics which are not desired.
  • one feature of my invention resides in the provision for a closer for doors and the like which comprises elongated housing means having longitudinally spaced ends, and slide means longitudinally slidable in the housing means in predetermined direction towards and away from one of the ends between a rest position and a working position.
  • Connecting means operatively connects the slide means with a door for effecting movement of the slide means between the positions thereof in response to movement of the door between its open and closed positions.
  • Biasing means permanently urges the slide means to its rest position.

  • the adjusting means comprises a pair of parallel rods slidably extending from the interior of the housing beyond the other of the ends thereof to the exterior of the housing and having first end portions located within and second end portions located without the housing.
  • An inner connecting member connects the first end portions within the housing and is associated with the biasing member.
  • An outer connecting member connects the outer end portions without the housing proximal to the aforementioned other end of the housing. Abutment means on the outer connecting member abuts against the aforementioned other end and causes the outer connecting member to move axially away from the other end of the housing at the will of a user. to thereby effect sliding of the rods and of the inner connecting member relative to the housing means with concomitant varying of the biasing force exerted by the biasing means.
  • the axial orientation of the parallel rods does not change, regardless of the adjustment of the biasing means, it is possible to provide reliable and highly effective sealing at the locations of the rods and the interior ofthe housing.
  • the present invention provides for a particularly compact and advantageous configuration of the housing.
  • both rods are located with their major portions exteriorly of the housing because the housing may then be configurated-Jn the region at which the rods extends exteriorly thereof-as a cylinder ac commodating the piston for the hydraulic damping device of the door closer.
  • the present invention can be similarly used with other constructions, for instance if instead of a single piston and a single piston rod, two pistons and two piston rods are provided located in the interior of the housing and each associated with a biasing means, for instance in form of helical biasing springs surrounding respective piston rod.
  • the housing itself is preferably constituted by two housing sections which are releasably connected with one another.

  • the housing section 10 has the cross-sectional configuration evident from FIG. 1, whereas the housing section 11 has the cross-sectional configuration which is clear from a comparison of FIGS. 1 and 2.
  • One sidewall of the housing section 10 is provided with an opening which can be closed by a releasable cover 12 for affording access to the interior.
  • a shaft 17 extends transversely through the housing section 10 and is connectable with a door or analogous structural element so as to rotate about its longitudinal axisin response to movement of the door from open to closed position, and vice versa.
  • the shaft is journaled in an antifriction bearing 14 mounted in a holding ring 13 which in turn issecured to the cover 12, for instance by spot welding, and a second antifriction bearing 15 is secured to the housing at the opposite sidewall from the cover 12.
  • a sealing gasket is associated with the antifriction bearing 15 to prevent escape from hydraulic fluidwhich is received in the interior of the housing sections 10 and 11-past the antifriction bearing 15.
  • a slide element 19 constituted by two transversely spaced parallel plate members 20 which are connected with one another by the rollers 21 freely rotatable with respect to the plate members 20.
  • the plate members 20 are provided with respective longitudinally extending slots 20a which are transversely aligned and which extend in longitudinal direction of the housing constituted by the sections 10 and 11.
  • the shaft 17 extends through the aligned slots 20a and carries intermediate the plate members 20 a cam portion 18 whose configuration is evident from FIGS. 1 and 2 and which is rigid with the shaft 17.
  • a roller ring 22 is also mounted on the shaft 17 freely rotatable thereto, and extends into one of the apertures 20a to roll along the edge faces bounding the same. This guides the slide member 19 with respect to the shaft 17 with a minimum of friction.
  • a piston rod 24 which is connectable with the slide member 19 via screws 23 of analogous fastening elements.
  • a braking arrangement 25 is provided which brakes movement of the slide member 19 in direction towards the left in FIGS. 1 and 2, when the slide member approaches its working position.
  • the construction of the braking arrangement 25 is not of importance for purposes of the present invention and, although it has been illustrated, will not be described.
  • the opposite end of the piston rod 24 from that which is connected with the slide member 19, is connected with a piston 36 received in the housing section 11.
  • a biasing spring 37 surrounds the piston rod 24 intermediate the piston 36 and an abutment member 32, bearing upon both.
  • the piston 36 is provided in suitable known manner-which therefore need not be further described-with one-way valve means and flow passages which permit the flow of hydraulic fluid from one to the other axial side of the piston 36 in response to movement of the same longitudinally of the housing section 11.
  • the circumferential wall of the housing section 11 is identified with reference numeral 27.
  • the housing section 11 is provided with a connecting flange 28 provided with recessed 29 which are located laterally outwardly of the circumferential wall 27.
