UNITED STATES PATENTS I 10 Claims, 3 Drawing Figures 3,3ll,944 4/1967 Dufek 16/159 X MOUNTING ARRANGEMENT FOR DOORS BACKGROUND OF THE INVENTION This invention relates to a mounting assembly for use in mounting a door on a door frame in which elongated lugs of a hinge support traverse the cover molding of the door frame and are received in a holder secured on the posterior side of the lining of the door frame.
So called hinge supports with a lug having a thread are well known, such lugs being screwed into previously drilled holes ofa wooden door frame. The depth of insertion of the lugs may be regulated by controlling the depth to which the lugs are screwed in. However, such hinge supports may be used for light doors only. Furthermore, these known hinge supports can be regulated only when the door has been removed from its hinge.
Heretofore. there has also been used three part hinge supports where two parts are screwed on to the door frame and where the parts may be regulated as to their depth by twisting or turning. However, these known hinge supports have the same disadvantage. Also such hinge supports are very expensive and are therefore only used with very heavy doors.
Furthermore, hinge supports are known having two pegs or lugs without a thread. Clamping means are arranged on such hinge supports upon the posterior side of the door frame liner, and these clamping means may be actuated by a setscrew so that both pegswhich pass through the molding strip of the frame may be fastened. However, such clamping means protrude out of the posterior side of the door frame liner to the extent that certain parts of the brickwork have to be chipped away, knocked out or otherwise removed in order that the door frame may fit with its clamping means into the opening in the brickwork. Also the door frame must be provided with a hole to provide access for a key or a similar means used to actuate the setscrew of the clamping means. This hole disadvantageously remains visible. Not only is the operation and actuation of the clamping means comparatively tedious, but furthermore, the resistance against tearing out (approximately 150 kg or 350 lbs) which can be reached by such an arrangement is too low for practical use so that the pegs of the door slip within the clamping means when the door is pushed too hard, or when, as frequently occurs under practical conditions of use, high loads are applied to the door.
Accordingly an object of the present invention is to overcome the disadvantages of these known prior art arrangements and to provide a mounting arrangement involving hinge supports which are simpler while being stronger and longer lasting than present known mounting arrangements while at the same time providing a particularly fast and simple assembly of the hinge supports and the doors along with a simple adjustment as to the mounting depth of the hinge support.
According to the present invention, the above object is achieved by providing a mounting arrangement consisting of a plastic holder for each hinge support upon the posterior side of a door frame and by providing the plastic holder with holes for receiving the lugs of the hinge support. The aforementioned holes have a cross sectional area less than the cross sectional area of the lugs so that the lugs are forced into the accepting holes in the plastic holder with an interference fit. Thus the lugs will be automatically, clampingly held and retained in position by the plastic material of the plastic holder, such holding force being increased by providing the lugs with an appropriate surface design which increases the holding friction.
In order to obtain such a mounting, a plastic material is needed which not only provides high tenacity and strength so that the mounting will not break when-the lug of the hinge support is forced therein, but which also provides a hard. spring-like elasticity in order to hold the lugs of the hinge support with a high radial clamping force when they are clamped by the plastic holder. The plastic material should also have a high resistance to abrasion so that the plastic material is abraded as little as possible by the surface profile of the lugs of the hinge support when such lugs are forced into the holes and also when the lugs are pulled back in order to regulate the depth of insertion of the lugs. This condition must be fulfilled in order to maintain the high resistance against pulling or tearing out. a
It has been found, according to the present invention, that the aforementioned criteria are fulfilled by using a poly-acetal plastic which has a tensile strength of approximately 700kg/cm an elongation at fracture of about a modulus of elasticity of about 1.25%. an elongation of about 28,000kg/cm". a friction coefficient (unlubricated) of about 0.1 to 0.3, and an abrasion resistance of about 20mg/l000 revolutions measured according to Norm ASTM Number D-1044 (Taber Abrasion, load: 1000g, Rad CS-l7). A polyacetal resin having these properties is, for example, commercially available under the tradename DELRIN 100, manufactured by Dupont. Experiments with a mounting made from this plastic showed that the resistance of a hinge support against pulling out after the first forcing-in. reached 280 kg and even more when both lugs of the hinge support were provided with a surface profile consisting of5 notches. Further experimentation showed that the resistance against pulling out of the hinge support was still about 200 kg after the lugs of the hinge support had been pulled out and were forced in again. The hinge support may simply be hammered in, while the correct depth is adjusted with the door already hung thereon, so that a solid and secure mounting is effected without requiring any screwing or the like. This solid and secure positioning and mounting occurs even when the hingeplate support has to be pulled out and is hammered in again. This relatively simple mode of fastening the hinge supports and the extremely high resistance against pulling out of the hinge supports makes it possible to effect the mounting without much strain or loss of time not only with light but even with heavy doors.
The surface profile of the lugs of the hinge support is important for the cooperation with the plastic mounting. It has been ,found, for example. that in using smooth lugs in the aforementioned experiment, that there was only a 65 kg pulling-out resistance. In the simplest case the surface profile may consist of notches which may simply be hammered into the lugs. By way of example, 5 notches utilized in the aforementioned experiment provided a resistance against pulling out of about 280 kg. It is only necessary to hammer a few more notches into the lugs if a higher resistance against tearing or pulling out is needed for particularly heavy doors. This may be done by a machine and also by hand.
Other features which are consideredcharacteristic of the invention are set forth in the appended claims.
Although the invention is illustrated and described in relationship to specific embodiments. it is nevertheless not intended to be limited to the details shown. since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
The construction and operation of the invention. however. together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
SUMMARY OF THE INVENTION A mounting assembly for use in mounting a door on a door frame includes a plastic holder mounted on a posterior part of the door frame. The plastic holder has elongated holes which are aligned with corresponding openings in the adjacent part of the door frame. A hinge support has elongated lugs which are constructed and arranged to pass through the openings in the door frame and to be received in the elongated holes in the plastic holder. The elongated holes are smaller than the lugs so as to provide an interference fit therebetween. and the plastic holder is made of a plastic material constructed such that the walls of the elongated holes yield elastically to biasingly clamp the lugs in the holes upon forcible insertion of the lugs in the holes. The lugs are provided with means for increasing the frictional drag between the lugs and the elongated holes.
BRIEF DESCRIPTION OF THEDRAWINGS FIG. 1 is a perspective view of a mounting arrangement according to one embodiment of the invention showing the holder and hinge support prior to assembly thereof.
FIG. 2 is a horizontal sectional view showing the mounting arrangement in assembled condition.
FIG. 3 is a perspective view of the holder on a larger scale.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings. FIG. 1 shows a door frame which includes. among other things. a lining 1 and a covering molding 2. A plastic holder 4 is fastened by means of a plurality of screws 3 onto the posterior side of the frame which posterior side faces the brickwork. A hinge support 6 having two lateral lugs 5 is provided to cooperate with the plastic holder 4. The plastic holder 4 has two accepting holes 7 for receiving the lugs 5 of the hinge support 6. The plastic holder 4 is made out of a plastic material having exceptionally high abrasion resistance. high strength and high springy rigidity (high modulus of elasticity). The diameters of the two accepting holes 7 are smaller than the diameter of the lugs 5 of the hinge support 6 by such an amount that the lugs 5 are wedged with a great wedging strength and high resistance against being pulled out after they have been hammered or otherwise driven into the holes 7 of the plastic holder 4. The two lugs 5 are furnished for this purpose with a surface profile 9 in the form of'several notches which increase the holding friction. and which are formed, for example, by hammering into the smooth lugs 5 of the hinge support.
The hinge support 6 may be made of metal. and the notches 9 may extend partially or about the entire circumference of the lugs 5. Also the notches 9 may be arranged spirally or in other arrangements.
The covering molding 2 is provided with predrilled holes 8 in which holes the double lugs 5 of the hinge support 6 are received. The lugs 5 pass through the holes 8 and into the plastic holder 4 when the hinge support 6 is hammered or otherwise driven into the plastic holder 4. The plastic holder 4 may be formed with such a flat shape that it fits into the void that usually exists between the frame lining and the brickwork.
The door is hung by driving the two lugs 5 of the hinge support 6 into the holes 7 of the plastic holder 4 to about two thirds of the depth. The workman may determine exactly the depth by hammering one or the other hinge support 6 a little deeper in. Thus the regulation of depth is possible when the door is being hung, and there is no need to screw. bolt or twist the hinge support 6. If the hinge support 6 was hammered in too deeply. it may be pulled out with a high ratio lever, and eventually hammered in to the correct depth. This latter procedure does not diminish the extraordinary high resistance against pulling out effected by the extraordinary high resistance against abrasion of the plastic which is used for the manufacture of the plastic holder 4.
The mounting of the hinge supports 6 by the aid of the aforedescribed plastic holder 4 according to this invention may be used for door frames manufactured out of wood. chipboard. steel or other materials. Instead of the abovementioned notches 9 on the lugs 5. the lugs 5 may be provided with a rough surface or other irregularities may be provided.
A particularly advantageous embodiment of the plastic holder 4 includes integrally molded cylindrical inserts which may be inserted into corresponding drilled holes in the posterior side of the lining l and arranged so that the plastic holder 4 is not connected to the lining 1 by the screws which are shown in FIG. 2. Preferably at least two inserts are provided in order that the plastic holder is prevented from rotating around the inserts. The advantage of connecting the plastic holder 4 with the lining 1 by the aid of these inserts resides in the fact that the requirement for screws is eliminated. and the mounting and assembly of the plastic holder becomes thereby faster and less expensive. Furthermore, the plastic holder may be placed in a simplified way into the correct location of the lining because the holes which serve to mate with the inserts are easily drilled into the lining with great precision by factory methods. Generally the inserts are capable of transferring very large forces upon the lining 1, that is forces which might be exerted by the hinge support 6 on the plastic holder and forces which would loosen or damage the screw connections. Thus assurance is provided that the plastic holder 4 will not push away the covering molding 2 from the lining 1. On the other hand. the screws in FIG. 2 which connect the plastic holder 4 with the covering 2 may be used to pull the covering 2 tightly towards the lining 1 when the covering 2 and lining l are glued together.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description and that it will be apparent that various changes may be' made in the form, construction, and
arrangements of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages. The form heretofore described being merely a preferred embodiment thereof.
