  • the hinge shaft 3 includes a helical shaft 3b formed under a shaft flange 3a positioned on a middle portion, a hexagonal portion 3c formed on a lower portion and having a hexagonal cross section fitted into the hexagonal hole 5c of the connector 5, and a thread 3d formed on a top portion and engaged into a nut 16.
  • a bushing 9 and a packing 10 are installed on an upper surface of the hinge shaft 3 which contacts the housing 1.
  • a piston 11 is engaged with the helical shaft 3b and is moved up and down within a cylinder chamber lc charged with fluid, depending upon a rotational direction of the helical shaft 3b, since a key 11a retained between an external surface of the piston 11 and a key seat lb formed on an inner surface of the housing 1.
  • a center passage way lib through which the fluid enters an inside of the piston 11 when the piston 11 moves down is formed through a lower end of the piston 11.

  • a pair of control valves 4 are mounted on an upper portion and a lower portion of the oil pressure control body 2, respectively, to control fluid flow through the passage ways le. Referring to Figs. 4 and 5, controlling the flows through the passage ways le is performed by rotating the adjusting rod 4a of the control valve 4 within the passage way 2a. That is, the adjusting rod 4a has a vertical flat surface 4b which defines a certain space for allowing the fluid to flow therethrough within the passage way 2a along the same 2a.
  • the inventive hinge type automatic door closer constructed in this manner is assembled as follows: First, the mounting plates 6 and 7 are mounted and fixed to the door 20 and the door-frame 30, respectively. Next, the connector 5 is engaged through the mounting plates 6 and 7 and then the nut 8 is engaged around the connector 5. Next, the hinge shaft 3 protruding from the housing 1 is inserted into the connector 5. During this process, the internal spline gear la and the spline gear 6a are engaged with each other. Finally, a nut 16 is engaged with the thread of the hinge shaft 3.
  • the piston 11 be lowered at predetermined distance from its top dead center before the insertion of the hinge shaft into the connector 5. This can be done by rotating the hinge shaft 3 by a predetermined angle or turn to lower the piston 11 and then retaining the bolt through the threaded hole Id into one of the grooves 3e, allowing the hinge shaft 3 to be locked with respect to the housing 1.
  • the door 20 remains closely contacted to the door-frame 30 by a restoring force by the spring 12 depressed by the piston 11.
  • the hinge shaft 3 is not rotated since it is fixed to the door-frame 30 through the connector 5 and the door-frame mounting plate 7, whereas the housing 1 is rotated since it is fixed to the door 20 through the internal spline gear la and the door mounting plate 6.
  • the piston 11 locked to the housing in the rotational movement by the key lb rotates around the helical shaft 3b to be lowered, depressing the fluid and the spring 12. That is, the operator opens the door 20 against a proper force, i.e., the force depressing the spring 12 and the fluid.
  • the piston 11 is lowered, the fluid within the cylinder chamber lc is introduced into the space within the piston 11 through the center passage way lib.
  • the fluid introduced into the piston 11 is then introduced into the upper two passage ways le and then the passage way 2a through various gaps, e.g., a gap between the helical shaft 3b and the inner surface of the piston 11.
  • the opening speed of the door 20 can be adjusted by rotating the adjusting rod 4a to control the cross section area for the flow of the fluid within the passage way 2a.
  • the piston blocks the passage way le of the middle one of three passage ways le.
  • the door being closed slowly and constantly is more slowly rotated, since it becomes more difficult for the fluid to be introduced into the passage way 2a. This is needed to reduce a shock or noise which may occurs when the door 20 is contacted to the door-frame 30.
  • the door 20 is first closed in a predetermined constant rotational speed and then is decelerated right before it is contacted to the door-frame 30.
  • Fig. 8 gives a modification of the present invention. As shown, contact between the hinge shaft 3 and the piston 11 is achieved through helical sliding surfaces 31 and 111 which are formed on a lower end of the hinge shaft 3 and an upper surface of the piston 11, respectively, and are fitted into each other. In this modification, when the housing 1 is rotated, the piston 11 is lowered, with its helical sliding surface 111 being misaligned with the helical sliding surface 31. Remainder components except the hinge shaft and the piston are identical to those in the foregoing embodiment.
  • Fig. 9 presents another modification of the present invention.
  • contact between the hinge shaft 3 and the piston 11 is achieved through slanted sliding surfaces 32 and 112 which are formed on a lower end of the hinge shaft 3 and an upper surface of the piston 11, respectively, and are fitted into each other.
  • the piston 11 is lowered, with its slanted sliding surface 112 sliding on the slanted sliding surface 32.
  • Remainder components except the hinge shaft and the piston are identical to those in the foregoing embodiment .
  • the housing 1 is designed to protrude out of the door 20 on a purpose of allowing the housing to be applicable to the established doors, it is possible that the housing is hidden from an outside view, when it is applied to a new door being manufactured.
  • the piston is adapted to vertically move under a proper pressure by the fluid, a proper closing and latching speed of the door is obtained. Further, the present invention permits an easy adjustment of the closing and latching speed through only a simple operation. Furthermore, the inventive door closer can be easily applied to the established doors without entailing a serious degradation of overall appearance; and can be mounted within a minimized space.
