Abstract

A hinge comprises a pair of hinge leaves each consisting of two parts (10,11) with projecting lugs (12-15) to receive and locate a hinge pin (21). The lugs (15) at opposite ends of the two leaf assemblies have blind sockets (22) so that when the leaf parts are secured to the members to be hinged together, the hinge pin is trapped and located in position. <IMAGE>

Description

SPECIFICATION Hinges Conventional hinges comprise a pair of leaves each with one or more apertured lugs which can interengage to receive a common hinge pin. The hinge pin is sometimes located after assembly by deforming its ends. This is not altogether satisfactory: it inCreases the manufacturing cost and if not performed properly the pin may subsequently fall out.

For some purposes also the fact that the pin is exposed at one or both ends is unsatisfactory or unsightly. Accordingly, it is an object of the invention to provide an improved hinge which wili answer at least some of these problems.

Broadly stated, the invention consists in a hinge including a hinge pin and a pair of hinge leaves, each having one or more fingers with apertures to receive the pin, both ends of the pin being totally concealed within the assembly.

In a preferred construction at least one of the leaves is in two separately formed parts each part having a blind hole to receive an end of the pin.

Conveniently, both leaves are in two separately formed parts, with the two parts of each leaf initially separated in the direction of the pin axis, and then closed towards each other to fit over the two ends of the pin.

According to a preferred feature of the invention at least one of the leaves is in two separately formed parts, and the two parts when finally assembled are located lengthwise by screws, rivets or fasteners, or by welding, brazing or bonding. In such case the two parts may be located by fastenings driven into one of the main components which are connected by the hinge.

The invention may be performed in various different ways and a number of embodiments will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is an exploded plan view illustrating the main components of the hinge, Figure 2A and 2B are end views onto the two leaf assemblies viewed in the direction of arrow X, Figures 3A and 3B are end views of the leaf assemblies seen in the direction of arrows Y, Figure 4 is a plan view of the assembled hinge when open, and Figure 5 is a perspective view of the hinge when closed.

In the hinge illustrated in Figure 1 to 5 each of the two leaves is in two parts. The top leaf consists of two parts 10 and 11, each with a pair of projecting lugs 12, 13, 14, 15 and each formed with holes 16 to receive fastening screws. Three of the lugs 12, 13, 14 are formed with through passages 20 to receive the hinge pin 21. The fourth lug 15 has an aligned blind socket 22 to fit over the end of the pin.

The other leaf of the hinge consists of an identical pair of leaf parts 10,11 also having apertured lugs 12 to 15 as illustrated. The fourth lug 15 again has a blind socket 22.

When assembled the two blind sockets 22 are at opposite ends and each opposing pair of leaf parts 10, 11 are married up with the lugs inter-engaged, the hinge pin 21 is inserted from the centre into both pairs and the two pairs are then moved inwards towards each other in the directions of the areas X and Y. When fully closed up as shown in Figure 4the fixing screws are then driven through the hole 16 into the door and door jamb or window as the case may be and these fixings simultaneously secure the adjacent left and right leaf halves of each leaf, thus ensuring that the pin is positively and fully concealed and, being totally embedded in the hinge, cannot become separated.

In a possible modification one leaf of the hinge is a one-piece unitary part with three apertured lugs and a fourth lug which has a blind socket. The other leaf is in two parts, one larger leaf part having three apertured lugs while the smaller leaf part has a lug with a blind socket. To assemble this hinge the larger leaf part is married up with the first leaf, the hinge pin is introduced and driven up into the blind socket in the fourth lug and the smaller part is driven over the projecting end of the pin.

Another possible method of interconnecting two hinge parts so as to cover and conceal the ends of the hinge pin relies on a snap fit. Both ends of the pin may be tapered and formed with an undercut groove. The corresponding hinge parts are provided with blind sockets each with resilient barbed fingers or detents, so designed that when the tapered end of the pin is inserted, the barbs snap into the groove and so prevent withdrawal of the pin.

In another possible modification (not illustrated ) the two halves of each hinge leaf are initially separate but after assembly with the hinge pin in position they are joined together. This may be by adhesive or by welding, for example, or any other ready form of attachment.

In some forms of the invention the two ends of the hinge pin are not totally concealed within the assembly but are simply locked positively within the assembly so that the hinge cannot escape. For instance, there may be a small aperture at one or both ends in the respective hinge leaves.

Thus, from another aspect, the invention consists broadly in a hinge including a hinge pin and a pair of hinge leaves each having one or more fingers with apertures to receive a pin and at least one of the leaves being in two parts which are separable in the direction of the pin axis, the pin being positively located lengthwise in position.
