[0001] The present invention relates to an apparatus for preventing the dislodging of a door hinge, in which a door shoe defining a cavity is attached to the bottom of a door and a spigot engageable within said cavity extends from a floor.
[0002] In many environments, doors are required that are considered to be robust and securable, to a greater extent than conventional doors used in most domestic and commercial situations. To provide the level of required robustness, doors of this type tend to be heavy and as such require hinges that rest on a solid base, as distinct from being hinged in a conventional cantilever style.
[0003] Known systems provide a shoe that is attached to the bottom of the door. The shoe defines a cavity that is configured to engage with a vertically extending spigot. This arrangement supports the weight of the door and allows hinging to take place. However, a problem exists with systems of this type in that it is possible for the cavity to be displaced with respect to the spigot if a significant force is applied to the door, possibly in response to an attempt being made to achieve unauthorised opening.
[0004] According to a first aspect of the present invention, there is provided an apparatus for preventing the dislodging of a door hinge, in which a door shoe defining a cavity is attached to the bottom of a door and a spigot engageable within said cavity extends from a floor, comprising: a collar locatable over said door shoe, wherein said collar includes inwardly inclined edges configured to restrain said spigot within said cavity.
[0005] According to a second aspect of the invention, there is provided a method of locating a door within a door frame, comprising the steps of: locating a collar over a door shoe; attaching said door shoe to the bottom of a door; fastening a spigot to a bottom portion of a doorframe; and engaging said spigot within a cavity defined by said door shoe, wherein said collar includes inwardly inclined edges configured to restrain said spigot within said cavity.

Figure 1
[0007] In an embodiment, to construct a door hinge, a door shoe defining a cavity is attached to the bottom of a door and a spigot engageable within this cavity extends from a floor.
[0008] An example of a spigot 101 is shown in Figure 1. The spigot 101 includes a threaded portion 102 and a spigot top 103. The spigot top 103 is receivable within the cavity of a door shoe to facilitate hinging. In the embodiment of Figure 1, the spigot top 103 is rotatable around the threaded portion 102 by the provision of a bearing race located within a race cavity 104.
Figure 2
[0009] To assemble the door hinge, an upper threaded retaining member 201 as shown in Figure 2, is deployed upon the threaded portion 102 of the spigot 101. This allows a floor mounted part of a door frame to be retained between the upper threaded retaining member 201 and a lower threaded securing member- described with reference to Figure 13 and Figure 14.
Figure 3
[0010] A washer 301 is deployed, as shown in Figure 3, over the threaded portion 102. The washer 301 is positioned to contact the upper threaded retaining member 201.
Figure 4
[0011] After receiving the washer 301, an attachment plate 401 as shown in Figure 4, is located over the threaded portion 201. The attachment plate 401 includes a hole 402 for receiving an attachment element engageable within a solid base. In the embodiment, additional holes 403, 404 and 405 are also provided for receiving additional attachment elements.
Figure 5
[0013] The first sub-assembly of Figure 4 is shown in an upright configuration in Figure 5. The spigot top 103 is presented at the top of the spigot for deployment within a door shoe. An example of an attaching element 501 is shown being located within the hole 402.
Figure 6
[0014] An apparatus for preventing the dislodging of a door hinge is shown in Figure 6. A door shoe, described with reference to Figure 7 and defining a cavity, is attached to the bottom of a door. The spigot 101 is engageable within this cavity and extends from a floor. To prevent the dislodging of the door hinge, the apparatus provides a collar 601 that is locatable over a door shoe. The collar includes inwardly inclined edges configured to restrain the spigot within the cavity.
[0015] The embodiment is provided with a base portion 602, along with a first side wall 603 defining a first inwardly inclined edge 604. In addition, the apparatus is provided with a second side wall 605 defining a second inwardly inclined edge 606.
[0016] The base 602 includes holes for accommodating attachments that secure a shoe to a door. In this embodiment, a first hole 611 is provided, along with a second hole 612 and a third hole 613.
Figure 7
[0017] An example of a door shoe 701 is shown in Figure 7. The door shoe 701 defines a cavity 702 for accommodating the spigot top 103. The door shoe also includes a first hole 711, a second hole 712 and a third hole 713 that align respectively with holes 611, 612 and 613 within the base portion 602 of the collar 601.
[0018] The collar 601 is locatable over the door shoe 701 by moving the collar in the direction of arrow 714.
Figure 8
[0019] After movement of the collar 601 in the direction of arrow 714, the collar 601 is located over the door shoe 701, as shown in Figure 8. Respective holes, including first hole 611 and first hole 711, have been aligned to facilitate attachment of the assembly to the bottom of a door.
Figure 9
[0021] A door 901 is shown in Figure 9, having a door bottom 902. The second sub-assembly 801, described with reference to Figure 8, is located towards an end 903 of the door bottom 902. The second sub-assembly 801 is then secured in place by means of securing devices 904 located through the aligned holes 611/711, 612/712, 613/713.
Figure 10
[0022] After attachment of the assembly 801 onto the door bottom 902, the door 901 may now be relocated for location within a door frame, whereupon the spigot 101 is engaged within the cavity 702.
Figure 11
[0024] A door frame foundation 1101 is shown in Figure 11. A lower threaded securing member 1102 is located upon the door frame foundation 1101. The lower threaded securing member 1102 includes a tapped hole 1103 for receiving the lower end of the threaded portion 102.
[0025] In addition, a second hole 1104 is provided for receiving an attachment element; thereby allowing the lower threaded securing member 1102 to be secured to the door frame foundation 1101.
Figure 12
[0026] After arranging the lower threaded securing member 1102, an attachment element 1201 is located through the second hole 1104 to achieve secure attachment, as shown in Figure 12.
Figure 13
[0027] To locate the door 901 within a door frame, as shown in Figure 13, a door frame base 1301 is located over the door frame foundation 1101. Thus, in this way, the lower threaded securing member is sandwiched between the door frame foundation 1101 and the door frame base 1301.
[0028] Full construction of the door frame is then achieved by the provision of a first vertical frame 1311, along with a cooperating second vertical door frame and a door frame top.
Figure 14
[0029] To continue with the door locating procedure, the first assembly, described with reference to Figure 5, is located above the door frame base 1301. The threaded portion 102 of the spigot 101 is located within the hole present within the door frame base to allow threaded engagement within the tapped hole 1103 of the lower threaded securing member 1102.
[0030] In this embodiment, as shown in Figure 14, the spigot 101 is further secured by the provision of the attachment plate 401. Thus, the attachment plate 401 is brought into contact with the door frame base 1301 and secured in place by means of the upper threaded securing member 201. The upper threaded securing member may take the form of a tapped nut, as shown in this embodiment, onto which additional torque may be deployed by the application of an appropriate spanner.
[0031] After securing the attachment plate 401 in place, attaching elements, such as attaching element 501 described with reference to Figure 5, are deployed through respective holes, including hole 402.
Figure 15
[0032] After securing the first assembly, as described with reference to Figure 14, the door, with its attached second sub-assembly, is located within the doorframe, as shown in Figure 15. The spigot top 103 is engaged within the cavity 702 defined by the door shoe. As previously described, a collar has been located over the door shoe, wherein the collar includes inwardly inclined edges 604/606 configured to restrain the spigot top within the cavity.
Figure 16
[0033] An end view of the door hinge assembly is shown in Figure 16, with the first sub-assembly engaged with the second sub-assembly. The spigot 101 is attachable to a floor, with the door shoe 701 being attachable to the bottom of a door.
[0034] The apparatus for preventing the dislodging of the spigot from the door shoe comprises the collar 601 that includes inwardly inclined edges configured to restrain the spigot within the cavity. In this way, when deployed, it is possible for force to be applied against the door which may result, temporarily, in this cavity 702 being displaced away from the spigot top 103. However, when such a condition occurs, the spigot top 103 is restrained by the first inwardly inclined edge 604 or by the second inwardly inclined edge 606. Thus, when the applied force subsides, the spigot top 103 returns to its location within the cavity 702.
[0035] The embodiment does not require modification to existing elements but, by the provision of the attachment plate 401 and the collar 601, the amount of force required to dislodge the door has increased substantially and experiments suggest that the integrity of other components will be undermined first if very high forces are deployed against the door.
