Definitions

  • ABSTRACT A door check includes a cam coupled to the door and havingopposite profiles against which a follower on one end of a lever is stressed by a spring, the other end of the lever actuating a damping cylinder. Particular shapes for the cam and for the orifice for escape from the cylinder are shown.
  • the present invention pertains to door checks or door closers to close a hinged door.
  • the check of the invention may be constructed to close a door swinging open in either direction from a closed position. it includes a hydraulic braking element which according to one feature of the invention is substantially independent of ambient temperature in its operation.
  • the door closer of the invention comprises a helicoid compression spring operating on a lever which carries a follower bearing against a cam which is fixed with respect to the door.
  • a hydraulic brake for damping the motion of the door includes a piston which is coupled to the lever, the piston working in a cylinder having a thin wall with a throttling orifice therethrough for the escape of hydraulic fluid from the cylinder on closing motion of the door.
  • the entire mechanism of the door check is enclosed'within a casing which may be integral in construction.
  • the spring In door closing apparatus of the type to which the invention relates, the spring must be quite stiff so that its stress increases rapidly as the door is opened. The result is that if the door is coupled directly to the spring so that with increasing open angle of the door the deformation of the spring increases, the effort required will increase with departure of the door from closed position.
  • the coupling between the door and the spring is made to possess a changing drive ratio so as to compensate or correct for this tendency.
  • C is the restoring couple or torque
  • d6 is a small variation in the angle of the door
  • to is the angular speed of opening or closing
  • F is the stress of the spring
  • Thedriving torque Cm makes it possible to define a fictitious available driving force or stress Fm for the spring.
  • Fm driving force
  • This force must be sufficient to overcome rapidly the inertia of the door so as to have the door closed within a few seconds. It is however necessary to limit the speed of the door in the vicinity of its closed position. It is hence necessary to add to the spring a brake.
  • .S is the effective cross-section of the damping piston
  • the rate Q at which hydraulic fluid is expelled from the brake cylinder by the piston on door closing is directly proportional to the speed of the piston thus:
  • the orifice which becomes effective at the end of the closing motion of the door, takes the shape of a thin annular slot between a hole and a conical adjusting stud adjacent thereto.
  • the effective size or section of this opening is not negligible, so that turbulence in the flow therethrough will be low. Its length is large or at least of the same order of magnitude as this width or effective dimension of the slot.
  • l is the axial length of the annular opening, i.e. in the direction of flow therethrough;
  • r is the mean radius thereof
  • a is the width of the slot, i.e. radially.
  • the closing speed of the door is directly related to the viscosity and hence to the temperature of the oil. This means that a compensating thermostat will be necessary. Moreover, this closing speed depends importantly on the width of the slot and on variations therein due for example to the deposit of foreign matter therein. Impurities in the oil will likewise have a substantial efi'ect on the door closing speed. Lastly, this closing speed depends on the available force Fm such that the closing time may be substantially dependent upon undesired friction.
  • the present invention is intended to surmount these difficulties in door checks.
  • the door check of the invention includes a particular shape for the orifice, the pressure drop across which is due to turbulent flow.
  • This orifice is formed in a thin walled diaphragm, and it constitutes a throttle or constriction whose length is substantially less than its diameter, instead of taking the shape of a narrow channel of narrow width obstructed by an adjusting element.
  • the rise in speed is greater, since the pressure drop Ap varies with the square and not with the first power of the rate of flow Q. Since the orifice is not annular, it is possible to obtain a sufficient pressure drop without unduly reducing the cross-sectional dimension a of the orifice. To increase the coefficient of pressure drop it is advantageous for the diaphragm to have sharp edges.
  • the door check may include a brake whose piston is directly coupled to the spring restoring or actuating lever while the orifice is stationary, being formed in a wall of the cylinder, only one orifice being provided.
  • the coefiicient A takes on only a single value and the drive ratio y remains practically constant.
  • the speed of closing to still varies as the product av Fm, such that a suitable choice of the spring and of the cam profile makes it possible to take advantage of the constancy in time of the turbulent flow in order to simplify the construction without reducing the quality of the result.
  • the throttling orifice is of intermediate size, making easier the formation and measurement thereof.
  • the spring and indeed the entire mechanism are enclosed in an integral housing where all of the elements are immersed in the fluid of the turbulent flow damper.
  • the housing comprises on one side a plate which closes off the cylinder ahead of the piston, except for the orifice.
  • the housing also includes the bearings for a pivot pin on which the door rests and by which its motion is coupled to the mechanism of the check.
  • a brake employing oil as a fluid makes it possible to provide permanent lubrication of the moving parts of the door check.
  • the torque Cr opposes opening of the door and must be overcome to open it. For this reason, and having regard to the necessity of providing a starting torque sufficient to hold the door closed against such forces as wind for example, it is desirable to give to the variation of Cr with door angle a shape declining as rapidly as possible. This means that a should increase rapidly as the door is opened. Moreover, it is desirable to reduce friction so as to diminish the average effort to be applied in opening the door, consistently with maintenance of a sufficient torque Cm, and to reduce the necessary energy, i.e. the size of an entire apparatus. The value of the driving torque Cm becomes less variable and unpredictable since it is less influenced by undesired factors such as friction at bearing surfaces, and the reversibility of the door is thereby increased.
  • a first embodiment of the invention employs a restoring torque which rapidly declines with door angle 0.
  • the spring and the brake are mounted in the usual fashion and are disposed on opposite sides of the axis of the restoring lever.
  • the articulation of the spring to this lever is provided by a knife edge and groove or socket combination, made of hardened steel, similar to those used in balances for weighing.
  • This arrangement differing from knuckle joints heretofore employed, makes it possible to reduce friction and also holds the force of reaction exerted by the lever on the spring in the axis of the spring in such fashion that there will be a reduced tendency for the spring to deflect laterally. I-Inece guiding friction on the spring is substantially reduced.
  • the principal pivots may be provided with needle bearings. This improves the reversibility of the door, i.e. its ability to close in the same position no matter from which side it had been opened.
  • the door check according to the invention thus possesses exceptional efficiency since the quantity '1 does not fall below 60 percent over the whole length of the door motion.
  • FIG. I is a plan sectional view of a door check according to the invention. 7
  • FIG. 2 is a sectional view in elevation along the line IIII of FIG. 1;v v
  • FIG. 3 is an axial sectional view of the damping piston in the check of FIGS. 1 and 2;
  • FIG. 4 is a sectional view of the aperture taken along the line IV-IV of FIG. 1;
  • FIG. 5 is a set of curves useful in describing operation of the door check of FIGS. 1 and 2;
  • FIG. 6 is a plan sectional view similar to that of FIG. 1 but showing a modified construction of the door check of the invention
  • FIG. 7 is a sectional view in elevation along the line II-II of FIG. 6;
  • FIG. 8 is a set of curves illustrating the operating characteristics of the door check of FIGS. 6 and 7.
  • the door check of the invention comprises an outer housing 1 having a cover 2 fastened to thehousing at the lugs 3.
  • the housing with its cover is intended to be disposed beneath the floor at the location of the door, at the hinged sidethereof.
  • the operating mechanism of the door closer is further disposed within a casing 4 closed with a cover plate 5 and with two additional closure members 6 and 7 which constitute bearings for the pivot pin 8 on which the door is hinged.
  • the casing can be adjusted in position with reference to the housing I by means of abutment screws 9 for adjustment in the horizontal plane and by three abutment screws 10 for adjustment in vertical planes.
  • the casing can then be locked in position with respect to the housing by means of the bolts 12 and the right-angle member llll seen in FIG. 2.
  • the interior of the casing 4 provides two substantially parallel spaces of approximately cylindrical shape.
  • the first of these contains a helicoidal compression spring 13 which may be made as shown of two parts having unlike spring constants.
  • the spring is supported at the right end, as seen in FIG. 11, on an adjustable abutment 14 supported at the cover 5 to the casing 4.
  • the other end of the spring 13 bears against and supports an abutment member 15 which bears against a lever 16 pivoted at a pin 17 fixed in the casing 4 for rotation of the lever about a vertical axis.
  • One arm of the lever namely that against which the spring 13 bears, carries a follower 18 which is stressed by action of the spring against a horizontal cam 19 fixed to the pivot pin 8 of the door.
  • the other arm of the lever is pivotally connected to a connecting rod 16' which is connected in turn' to a damping piston 20 working in a cylindrical cavity formed in the casing 4. It will be seen that as the compression spring 13 expands to conditions of lower stress, the piston 20 will be driven to the right as seen in FIG. I and vice versa.
  • the door pin 8 has affixed thereto a second cam 21 cooperating with a follower 22 also disposed on the lever 16.
  • the piston 20 has two passages extending through it with valves in those passages.
  • a ball 23 imprisoned behind a cage 24 permits the flow of hydraulic fluid through the piston from left to right as seen in FIG. ll.
  • a ball 25 held against its seat by an adjustable spring 26 constitutes a safety valve'which permits hydraulic fluid to flow through the piston in the opposite direction upon the build-up of excessive pressure on the right side of the piston.
  • a partition within the casing defined by the elements 4 and 5 closes off a space 27 at the right of the piston from the remainder of the interior of the casing 4.
  • the chamber 27 is thus bounded in part by a wall 27.
  • the wall 27 has an opening therein which is closed by a hollow cylindrical plug 28.
  • the plug shown in detail in FIG. 4, has apertures 30 and 31 through its opposite walls. The smaller, of these apertures 30 is formed at the bottom of a counterbore 32, so that the aperture 30 exists in a thin wall and has an axial length (perpendicularly to the axis of the plug), for example 0.3 mm., small by comparison with its diameter which may be of the order of 1 mm.
  • a threaded closing member 29 is formed with a conical cavity at the lower end thereof and can be adjusted vertically within the plug 28.
  • the lower edge of the member 29 thus constitutes a blade which according to the adjustment of the member 29 effects greater or less obturation of the aperture 30.
  • the member 29 provides a thin, sharp-edged diaphragm which can be advanced adjustably across the aperture 30.
  • the member rests at a knife edge against a complementarily slotted abutment member 33 affixed to the lever 16.
  • the knife edge and its socket on the member 33 may desirably be made of hardened steel.
  • the door pivot 8, the lever 16 and the roller 18 may be provided with ball or needle bearings as seen in FIGS. 1 and 2, to improve the operation of the apparatus and the uniformity of its operation in both directions of door opening.
  • the casing 4 is filled with fluid oil and is provided with seals or gaskets as indicated in the drawings.
  • FIG. 1 shows the door check in closed position.
  • the door being openable in either direction, the cam 19 has two slopes of the same or similar profile so that'the operation of the door and also that of the lever 16 is the same in either direction.
  • the cam profile includes a concave portion 34 in which the follower 18 rests when the door is in closed position. To the two sides of this hollow portion there extend rapidly rising portions 35 which are substantially symmetric in the plane of the door.
  • each of the cam surfaces 35 includes initially a neutral zone extending over a few degrees and having a substantially constant slope. This makes it possible to give a fixed, known value to the force holding the door in closed position. The cam then changes slope so that the torque-angle characteristic declines with further opening of the door and notwithstanding the increasing stressing of the spring.
  • the restoring torque is reduced to 50 percent of its initial value and after being rotated through 90 the torque is reduced to about 35 percent of its initial value.
  • each cam surface is terminated with a notch such as 36, provided to cooperate with the follower.
  • the notches 36 function as detents to hold the door in completely open position, for example after rotation of 105 from the closed position of the door. To reach this position it is sufficient to push the door far enough so that the follower l8 falls into the notch.
  • the torque-angle characteristic is sufficiently declining so that it is not necessary to provide a supplementary orifice for escape of oil from the chamber 27 to be operative at the start of the closing motion.
  • the door check operates in exactly the same way when the door is opened in the opposite sense, i.e. counterclockwise.
  • the slight inequality of the two profiles of cam 19 visible in FIG. 1 is simply due to the need to compensate for the fact that the motion of the follower 18 is circular.
  • By making the two profiles slightly different it is possible to obtain two identical closure, i.e. torque-angle, characteristics.
  • the valve 25 does not come into play except in the event of malfunction which makes it necessary to relieve excess pressure in the chamber 27.
  • FIG. 5 shows, in arbitrary units along the vertical scale, a graphical representation of the principal characteristics of the door check of FIGS. 1 and 2.
  • the axis of abscissae represents compression of the spring but is also graduated in degrees of opening of the door.
  • Curve C represents the torque exerted by the check on the door in the absence of friction in the check.
  • the maximum value thereof is rapidly attained in the vicinity of the closed position of the door.
  • this is adjusted, e.g. at the element 14 in FIG. 1, to a value of about 45 Nm such that the door will not oscillate about its closed position and resists well the effect of wind.
  • the effort necessary to be applied to the door to open it is relatively high but it need be applied for only a short time, and the consequence is an agreeable sensation for the user since the force required of him rapidly and smoothly declines as his arm moves the door.
  • FIGS. 6 and 7 employs a construction similar to that described herein with reference to FIGS. 1 and 2, corresponding elements of structure having applied thereto the same reference characters.
  • the pivot 17 for the lever 16 is displaced to the side of the casing 4 so that the coupling at 37 of the link 16' and at 38, of the spring 13 are side by side. This permits a large change in compression of the spring, over the course of motion for the door, with an initial low compression of the spring when the door is closed.
  • the mounting of the spring has been inverted.
  • the spring is compressed between a washer 14, at the end of the rod 39 adjustably screwed to the housing, and the washer 15 which is fixed to the stirrup 40.
  • This stirrup in turn is pivoted at 38 to the lever 16.
  • the rod 39 and the stirrup 40 are hence subjected to tension by the spring 13.
  • the second cam 21 of FIGS. 1 and 2 is absent, the portions of the single cam 19 remote from the parts thereof engaged by follower 18 being engageable with a follower 22 having the same function as the follower 22 of FIG. 1.
  • the lever is made of two plates 16a and 16b fastened together to provide the various pivots 17, 18, 37 and 38.
  • the cam .19 and the stirrup 40 pass between the two plates of the lever.
  • the pivot 38 is located in position to remain out of the way of the cam 19 for all positions of the cam and lever.
  • the knife edge and groove articulation 15 and 33 of FIG. 1 is not necessary with the large displacement of pivot 38 from the washer 15 of the spring, because Mil this large displacement reduces the tendency of the spring to flex laterally.
  • the frictional losses are smaller than in the devices of the prior art and this insures a high efficiency.
  • FIG. 8 shows the characteristics obtained with this construction. It will be observed that the decline in the torque C with increasing 0 is smaller than that of the embodiment of FIGS. 1 and 2. Indeed this torque, and hence the effort required of the user to open the door, increases as the door approaches fully opened position.
  • the closing speed to however has a characteristic similar to that of the embodiment first described.
