3 Claims.

This invention relates to a hinge for hingedly connecting two members together, of the general class havin pintles and channeled knuckles which engage with each other, and to a method for hingedly connecting two members together.

Hinges of this general class have been provided in the past. In order to connect two members together with them, however, it has, to my knowledge, always been necessary to connect them first at one point along the edge to be joined, and subsequently to connect them at a spaced apart point. Connecting members in this way is relatively awkward and lirnits the applicability of the construction.

I have invented a hinge of this class which has a wider applicability.

It is an object of the invention to provide a hinge, the leaves of which can be caused to engage with each other by causing the channeled knuckles to engage with the pintles simultaneously at all points along the edges to be connected, and which will lock together so that disengagement is impossible upon slight rotation.

It is a further object of this invention to provide a hinge having the above-mentioned characteristics which is cheap to manufacture.

With these and other objects in view, a hinge according to my invention comprises two similar leaves, each having a base for mounting it, a pintle carried by said base, and a knucklecarried by said base in spaced apart relation to said pintle. The knuckle is formed with a channel, the longitudinal axis of which aligns with the longitudinal axi of the pintle. The hinge and the method for hingedly connecting two members together, according to my invention, will be apparent after reference to the following detailed specification read in conjunction with the drawings.

In the drawings:

Figure 1 is a View showing two members about to be hingedly connected according to the present invention,

Figure 2 is a view showing the same two members hingedly connected,

Figure 3 is a sectional view showing the relation of the pintle and a cc-operating knuckle im mediately after they have been brought together,

Figure 4 is a sectional View showing the pintle and the knuckle after they have been rotated.

Referring to the drawings, a complete hinge according to my invention will be seen to comprise a leaf Ill and leaf N having bases [2 and I3 respectively for mountingthem on the edges of members [4 and [5 that are to be hingedly connected together. The leaf H3 is similar to the leaf l I in construction and like numerals on each leaf refer to like parts in the portions of the specification that follow.

Each of the leaves will be seen to have a pintle it carried between spaced apart shoulders [land it which are supported by arms l9 and 20 on the base 12, and a knuckle zl also supported by the arm 22 on the base E2. The knuckle 2| in the embodiment of the invention shown is formed with a channel 23 bybending the upper extremity of the arm 22 in a substantial U shape. The longitudinal axis of the channel 23 aligns with the longitudinal axis of the pintle 1'8 and the cross section of the channel 23 is designed to rotatably engage with the pintle l 6 of a co-operating leaf. The shoulders ill and I8 arev spaced apart to snugly receive therebetween a knuckle of a co-operating leaf.

The method for connecting the members M and it together will be apparent from the drawings. The knuckle 2i and pintle it carried by the base l2 are mounted on the member Hi asshown, and the corresponding knuckle and pintle carried by the base l3 are mounted on'the member [5. The

members It and i5 are then rotated to cause the mouths of the channels- 23 formed in each of the knuckles to face each other so that the leaves Ill and l I can be brought into engagement with each other whereby to cause the knuckle of each leaf to engage with the pintle of the other. After the leaves have been so brought into engagement with each other, it is merely necessary to rotate one of the members with respect totheother. Upon rotation of the members M and 15 with respect to each other it will be apparent that the mouths of the channels formed in the knuckles 2| will no longer face each other, and that each channel will lock with the pintle it engages to prevent the two members from parting.

The channel 23 is formed with one of its sides extended as at 24 to aid the locking function of the knuckles.

In use stop means for preventing the members it and i5 from returning to the position in which the leaves it and H can disengage can be employed. It will further be apparent to those skilled in the art that the leaves could be designed by changing the angl of the channels 23 with respect to the bases so that they could be united when the members M and [5 are at any predetermined angle with respect to each other.

In the drawings I have shown a single leaf having the knuckle and pintle mounted on it. It will be apparent, however, that a separate leaf could be formed for the pintle and for the knuckle.

Embodiments of my invention other than the 3 one shown in the drawings will be apparent to those skilled in the art. I do not intend, therefore, that the scope of my invention should be limited by the foregoing specification except by the limitations expressed in the following claims.

What I claim as my invention is:

l. A hinge leaf, for co-operation with a similar hinge leaf, comprising a base having three spaced apart arms extending therefrom, the upper extremities of two of said arms that are adjacent each other being formed into shoulders, a pintle extending between said two shoulders, the upper extremity of the remaining arm being formed into a U shape to form a channeled knuckle, said channel having its longitudinal axis aligned with the longitudinal axis of said pintle, said shoulders being spaced apart to snugly receive therebetween a knuckle equal in length to the length of said above-mentioned knuckle, said channel formed in said first mentioned knuckle being designed to engage with a pintle having dimensions similar to said above-mentioned pintle.

2. A hinge leaf for co-operation with a similar hinge leaf to form a hinge, comprising a base for mounting said leaf, a pintle carried by said base, and. a knuckle carried by said base in spaced relation to said pintle, said knuckle being formed with an open channel, the longitudinal axis of said channel being aligned with the longitudinal .axis of said pintle, said channel 4 formed in said knuckle having a length that corresponds to the length of said pintle to engage with a pintle on a similar hinge leaf having a pintle dimension similar to said first mentioned pintle.

3. A hinge leaf for co-operation with a similar hinge leaf, comprising a base, two spaced apart shoulders carried by said base, a pintle extending between said two shoulders, a knuckle carried by said base, said knuckle being formed with a channel having its longitudinal axis spaced from and aligned with the longitudinal axis of said pintle, said shoulders being spaced apart to snugly receive therebetween a knuckle equal in length to the length of said above-mentioned knuckle, said channel formed in said knuckle being designed to engage with a pintle having dimensions similar to said above-mentioned pintle.
