CHICAGO, ILLINOIS, A COREORATION OF ILLINOIS HOLDING DEVICE Applicaticn filed May 31,
provide a holding means for doors, hingedl windows and the like, which is capable ofV adjustmentwhereby the open position at which 'fe the door or window is held,jmay be selectively determined by means of a simple and readily manipulated adjusting device.
Anotherobjeet of this invention is to provide a holding device which has a more eflicient holding action at a greater number of open positions of the door and is highly eilicient for holding doors-when open to any angular position within range of one hundred' and eighty degrees' from the closedpositioii. Another object of this invention isV to pro vide a holding device of the above described character which is strong, durable and em# bodies certain principles of operationand structural 'A characteristics which eliminate objections heretofore encountered in holding devicesV of this general kind. f I
The holding device of the present invention is adapted torbe'connected between the'door or Avthe like and the sill therefor, and it embodiesparts adapted for frictional binding upon relative movement therebetween such as is caused when the door is moved inopen-V ing and although many of the advantages of the present invention are realized 'irrespective of the location of the friction holding means, certain additional advantages are realized when the friction holding means is lo cated at the pivot mounted at the sill;
Devicesof this characterusually provide a pivot carried by either the door or the door sill together with Vmeans mounted on the pivot and connected to the other of said parts, that is, the door and the door sill, as the case may be. This connection is sometimes provided by means of a link pivoted to the part' mounted on the first pivot and in turn, pivoted Vto the door or door sill, as the case maybe.
Constructions ofthe above type are in effect, four-bar linkages utilizing the door, with its hinge asthe pivot center, as' one link with a 1929. Serial No. 367,264.
pair of links pivoted together and connecting the door and the door sill respectively. In suoli constructions, there are three pivots, one at the door, one at the door sill and one between the links and depending upon the position of the door to the door sill, these various pivoted parts move at variable angular velocities for uniform angular velocity of the door.
Where frictional surfaces are employed, it is obvious that a relative movement is necessary to bring the friction faces in holding relationship'and accordingly, the most eflicient results are realized when the holding device is placed at the pivot, the parts of which undergo .the greatest `relative movement throughout that arc of the opening movement of the door at which holding is desired. Due to this fact, improved results are realized by locating the friction holding faces at one pivot in installations where holding is desired throughout a prescribed arc and at another pivot when the holding is desiredthroughout a different portion of the arc of opening movement.
In. the preferred form 0f the present invention, only one link is employed between the door and the door sill which link is provided With a sliding connection with the door and with a pivoted attachment to the door sill. The friction faces are located at, and take advantage of the relative movement between, the pivot parts carried by the door sill which, in the type of device illustrated, results in a very eilicient and effective holding action throughout the entire range of opening movement of the door up to and including the position of one hundred and eighty degrees from the closed position.
rllhis arrangement produces a translated movement at the pivot commensurate with the movement of the door, whereby suflicient movement between the friction parts is produced to hold the door by the movement of the door through any portion of its arcto its Ymaximum one hundred and eighty `degree open position. Y
Considering now the present invention froma different viewpoint, friction faces are here employed of a simple and eliicient chareen acter in a construction which eliminates objections heretofore encountered in devices of this general kind. Where the friction faces aet laterally, that is, in a radial direction to the pivot surface, difficulty has been heretofore encountered in that the holding forces are found to damage and distort the pivot bearing. This objection has rendered devices of this character objectionable for use both in cases where the holding device is mounted directly between the door and door sill, but more particularly where the holding device is mounted in connection with a door closing and checking device. In cases where the door checking and holding device is located in the sill, the objectionable operation referred to, causes distortion, wear and other damage to the pivot shaft of the door checking and holding device.
rlhe present invention by the novel construction hereinafter described eliminates this objectionable feature and provides means for backing up the friction holding surface, whereby a constricting or pinching friction holding is 1riroduced wholly removed from the shaftof the pivot so that the pivot bearing surface is maintained free from bending strains, wear or other harm.
It will therefore appeal', that the present invention resides in the novel construction of the friction holding device, the advantages of which may be realized in any type of friction holding device, that is, with respect to the kind of connecting linkage and location of the pivot and also that additional advantages are claimed for the present invention when the particular type of friction device is mounted at the pivot carried by the door sill and connected by means of an arm having a sliding connection with the door.
lt is to be also understood that the present invention contemplates a door holding arm per se, that is, a holder for the door mounted without a checkingr and closing device connected therewith and also a holder to be used in connection with a closing and checking device acting in addition, as the connecting means for actuating the door checking and closing device. ln this last combination, special advantages are realized in installations where the door checking and holding device is mounted in the sill.
lt will therefore appear that a further object of this invention is to provide a device which produces the above described advantages and which eliminates the objections referred to.
Other objects not specifically enumerated will readily appear to one skilled in the art as the description of onev particular embodiment of the invention proceeds. The embodiment hereinafter described is given merely by way of illustration and is not to be considered as limiting the invention in any r respect, as the scope of the invention may be determined from an understanding of the illustrated embodiment and an appreciation of the advantages which the present invention produces therein.
The following description will be more readily understood by referring to the accompanying drawings in which Figure 1 is a fragmentary view partly in cross section of a door closing and checking device provided with an actuating and holding arm constructed in accordance with the present invention.
Figure 2 is a cross sectional view taken on the line 2 2 of Figure 1 and looking in the direction of the arrows.
Figure 3 is a perspective View of the actuating arm shown in Figure 1.
Figure 4 is a side elevational view, partly in cross section of a door holding arm constructed in accordance with the present invention and mounted independently of a door checking and closing device.
Figure 5 is a cross sectional view taken on the line 5-5 of Figure 4 and looking in the direction of the arrows.
Figure 6 is a view similar to Figure 3 of the arm, shown in Figure 4, and
Figure .7 is a perspective view in inverted position, of the stationary part of the device shown in Figure 4.
Figure 8 is an elevational view showing the manner of mounting the door check, it being understood that the modified form shown in Figure 4 will be mounted in the same relationship with the plate 30, screwed directly to the upper surface of the door frame.
By referring to the drawings, it will be noted that in Figures 1 to 3 inclusive, the
present invention is illustrated as embodied in a door closing, checking and holding device, comprising a case 10, having a base plate 11. The fluid checking and clsing mechanism is contained within the casing 10 and is of any suitable construction so as to give the desired controlled movement to the shaft 12 whereby through the connecting arm 13, the control closing movement is imparted to the door. The internal construction of the door checking and closing device is not here disclosed as it per se constitutes no part of the present invention. i
It will be suiiicient to understand that the arm 13 is rigidly mounted on the shaft 12 by with a tooth of the ratchet collar so that the sleeve is caused to rotate with the arm 13. In the present construction, the sleeve is connected to a closing spring and the ratchet and dog mechanism are provided for the purpose of adjusting the spring.
Mounted on the sleeve 15 is an annulus 18, stationarily held by means of the flange 19, witlirthe base plate 11. The annulus 18V is provided with an inner surface 20, cylindrical in shape and disposed concentrically with respect to the shaft 12 and with an outer surface 21 cylindrical in shape and disposed eccentrically to the shaft. The eccentricity of the outer surface is clearly shown in Figure 2.
Mounted on the arm 13 is an upstanding lug 22 which is either integral therewith or otherwise rigidly attached and provided with a screw threaded opening 23. Mounted in the screw threaded opening is a screw bolt 24having a reduced end 25 on which is mounted the shoe 26 having the recess 27 therein for receiving the end of the bolt. The recess is pref" erably slightly larger than the end of the bolt whereby the shoe is held against displacement but is free to adapt itself through tilting movement to the outside surface 21Y of the annulus 18. The inner surface of the shoe is formed on an arc of a circle so as to conform to the surface 21 of the annulus. The shoe is capable of movement toward and away from the surface 21 by adjustment of J[he bolt 24.
By this arrangement it will appear that the enlarged portion of the eccentric annulus 21 maT be initially disposed in the -desired manner by adjustment thereof in the base plate 11, and securely held by any suitable means. Thereafter by a proper adjustment of the shoe, the shoe may be brought into frictional binding relationship with the surface 21 upon a. certain predetermined relative movement between the arm 13 and the annulus 18.
It will also be appreciated that inasmuch as the sleeve 15 is fixed to rotate with the arm 13 it offers a supporting and backing up action to the annulus 18 whereby strain on the pivot is relieved and holding action is accomplished by a pinching or constricting action on the inner and outer surfaces of the annulus 18by the sleeve 15 and the shoe on opposite sides thereof. Accordingly there is no tendency toward bodily displacement of the shaft resulting in detrimental wear and distortion of the bearing.
Referring now to Figures 4 to 7 inclusive, it will be noted that the device is quite similar in principle except that no door checking and closing device is employed. In this instance, the pivot bracket 30 is secured by means of the screws 31 to the door sill 32. The bracket is provided with a central lug 33 having a screw threaded bore 34 extending upwardly in the center thereof.
Position-ed around the lug 33 is a depending annulus 35 which is provided with a cylindrical surface 36 on the inside thereof, disposed concentrically with the bore and an outside cylindrical surface 37 disposed eccentrically to the inner surface 36 and bore 34. The arm 42 in this caseis provided with an opening 38 through which is disposed the bolt V39 mounted in the threaded bore 34. The bolt is provided with a head 40 and washer 41 for holding the arm against downward displacement. Y
The arm 42 is in addition provided with an upstanding annulus 43 'having an outer cylindrical surface concentrically disposed relativeV to the center of the opening 38 and constructed and adapted for bearing engagement with the inside surface 36 of the iiange 35. The arm is also provided with a lug 22, bolt 45 and shoe 46, all similar to the corresponding parts described in connection with the'device shown in Figures 1 to 3- inclusive.
The shoe in this case can be of greater height if desired, because no clearance is necessary for accommodating dog 17 as in the former case. j
In this form of invention, it will be obvious that the upstanding annulus 43 will offer a backingiand supporting action for the annulus 35 to produce the above described pinching and constricting action between the shoe and the flange. The bearingfor the arm 42 is provided between the surfaces 36 and the outside surface of the collar 43.
In either modification the opposite end of the arm is provided with a pivot opening 47 by which the arm is connected for movement with the door. This may be accomplished by a link connection between the door and the end of the arm but in the present instance, it is preferable to employ a sliding connection. When a sliding connection is employed, the arm is preferably crooked at its end as shown at 48 so as to provide the necessary clearance and is provided with a pivoted shoe at the end thereof mounted for free sliding movement in a guideway carried on the top surface of the door.
It will readily appear that the present disclosure constitutes an illustration of mechanism which embodies all of the above stated advantages. The present illustration is not to be considered as limiting the invention in any respect as any and all modifications are contemplated as may come within the scope of the appended claims.
I claim:
