  • This invention relates to the improvement of apparatus for attaching a swing door provided with a door check, and more specifically relates to apparatus provided with the means for closing the door automatically.
  • the apparatus is attached to upper part of the swing door supported by a pivot shaft.
  • the object of this invention is to present novel and improved door check means by which the door can be opened easily, and on closing when the acceleration is applied to the door in the direction of closing, this can be checked so that the shock generated when the door is closed can be eliminated. It works easily and smoothly and has a good appearance and very simple and economical construction. Such apparatus as described above can be obtained by this invention.
  • the apparatus ac cording to the present invention comprises an outer cylinder to be attached on a door side, an inner cylinder engaged freely rotatably in said outer cylinder with a space between the cylinders, a shaft for suspending an upper part of the door disposed in an inner part of said inner cylinder freely slidably and engaged with a bearing in the door frame, a spring means workable in the direction for closing said door in the space between said outer cylinder and inner cylinder, and another spring means workable in the direction for opening said door, the spring means working in the direction for opening said door being construct-F ed in such a way that it works more weakly than the spring means Working in the direction for closing said door.
  • FIG. 1 is a perspective view of a door with a door check in accordance with the invention.
  • FIG. 2 is a perspective view of each of the disassembled parts.
  • FIG. 3 is a substantial enlarged longitudinal sectional view.
  • FIG. 4 is a diagram showing the relation between the operation of the spring and the angle of opening of the door.
  • FIG. 1 In FIG. 1 are shown the door 1, and the door frame 2.
  • the lower part of said door is supported by the pivot shaft 3.
  • To the upper part of said door is attached the outer cylinder 5 having a shaft 4 free movably in and out.
  • To said door frame is attached a bearing 6 in which said shaft 4 is engaged. Said shaft 4 is inserted in an axial hole 7 of said bearing 6, and through said pivot shaft 3, the door 1 is attached to the door frame 2 so as to be freely rotatable.
  • said outer cylinder 5 is opened at both ends and attached to the upper face of the door 1 by an attaching arm 8 formed integrally on the upper part thereof.
  • Said arm 8 is compposed of the longitudinal part 56 and the part 57 bent at right angles thereto.
  • Said longitudinal part 56 has a number of holes 59 drilled for said attachment to the door by screws 9 threaded in said holes.
  • the inner cylinder 10 is inserted in said outer cylinder with the space 11 remained.
  • the lower part of said outer cylinder rides on the flange 12 of said inner cylinder, and has the groove 13 on the upper part thereof, in said groove 13 are disposed the steel balls 14, which are covered by the cover 15.
  • Screws 17, 17 are threaded into the half cut female threads 16a, 16b threaded on the upper end of said cover and said inner cylinder, thereby the outer cylinder is rotatable relative to the inner cylinder.
  • each one end 20, 21 of both said spring means is engaged free movably in the longitudinal groove 45a, and the other ends 23, 24 are engaged by the holes 25, 26 drilled in the cover 15 and the flange 12 of the inner cylinder.
  • the upper spring means 18 is urged in the direction for closing the door
  • the lower spring means 19 is urged in the direction for opening the door and each member is designed in such a way that the tendency to close the door is greater than the tendency to open the door.
  • Shaft 4 has the female threads 27 therein, and is inserted axially in said inner cylinder 10 freely slidably, and the outer shape thereof is formed polygonal, such as square, hexagonal etc., to be moved up and down by the threaded bar 28 in the axial hole 29 of the inner cylinder which is also drilled in corresponding polygonal shape.
  • Threaded bar 28 has the male threaded part 32 engaged with the female thread 27 of the shaft 4, by this threading operation said shaft 4 can be moved up and down.
  • Threaded bar 28 has the flange 38 at its lower part.
  • Bushes 30 and 35 are disposed respectively above and under said flange 38 and each of them is passed through by the holes 31 and 31a and placed in the hole of said inner cylinder.
  • Said bush 30 has the square part 50 and the circular part 51 and the shoulder 52 formed by them, and at this shoulder 52 it is checked by the cylindrical step of the inner cylinder 10 corresponding to this shoulder.
  • Said bush 35 has the half female thread 36, the half female thread 36a corresponding to this is provided in the bottom of said inner cylinder 10, into these female threads is threaded the screw 37, thereby said bush is fixed in the inner cylinder.
  • said threaded bar 28 can be rotated at fixed position in the inner cylinder 10 with no up and down sliding motion.
  • Attaching arm 40 integral with said bearing 6 is composed of the longitudinal part 54 and the part 55 bent at right angle thereto and the bearing is attached by threading the screws 41 into the lower face of the door frame through the holes 58 drilled in said longitudinal part 54.
  • shaft 4 When the door is put in the door frame, shaft 4 is drawn in until the face of the cover 15 and the axial hole 42 fits in the axial hole 7 of the bearing and then said threaded bar 28 is rotated in the right hand direction thereby the shaft 4 is inserted into said axial hole 7 then the door 1 is put in the door frame 2.
  • the axial hole too is formed polygonal corresponding to the outer shape of the shaft to prevent the relative rotation of said shaft 4 and the axial hole 7.
  • bearing 6-shaft 4- cover 16-inner cylinder 10 are connected integrally and the outer cylinder rotates around said inner cylinder.
  • FIG. 4 is the graph showing this relation approximately.
  • line A shows the turning effort of the spring means 18 on the closing side
  • line B shows the turning elfort of the spring means on the opening side
  • line C shows the composite turning effort of said both springs.
  • the spring means 18 is twisted further, and reversely the spring means 19 is untwisted the composite turning effort thereof, is the strength in such a degree that on opening the door it can be opened smoothly, and when it is opened nearly in right angle the door may return slowly and automatically. While, during the period that said opened door comes to the closed state the spring means 18 is untwisted, and reversely the spring means 19 is twisted and the door beginning to rotate gently in the closing direction tends to increase its rotational speed but the spring means 19 serves to brake it thereby the door is closed gently.
  • the strength and twisting of said two sets of spring means can be obtained the desired slow and fast closing and opening motion of the door.
  • Intermediate element 43 engaging with the inner cylinder is interposed between the two spring means.
  • Said intermediate element 43 has the protrusion 44 protruded in the hole 43a thereof and engaged slidably up and down but unrotatably in the recess 45 cut in the inner cylinder, thereby the eccentricity due to compression of the spring is prevented, further the sum of the height of both springs is kept nearly at average value and prevents the abnormal motion between mutual springs and both opening and closing operation of the door become more smoothly.
  • the winding operation in on one hand of the spring and the unwinding operation in the other hand can be performed nearly in the central part of the outer cylinder.
  • said intermediate element can be engaged with the shoulder part 46 of the inner cylinder, thereby the interference between both springs can be cut oif in the closed state of the door and the occurence of the obstacles such as creep and relaxation can be prevented.
  • Annular groove 47 formed on the lower face of said outer cylinder has the stopper 48 at one part thereof.
  • the protrusion 49 is rotatable in said groove and provided in the flange 12 of the inner cylinder. These protrusions and the stopper in the groove regulate the angle of rotation of the outer cylinder.
  • Said each member can be produced by various process, but the manufacturing process utilizing die casting is very advantageous.
