This invention pertains to hinges of a type substantially similar to that constituting the subject matter of my pending application SerialNumber 105,762, filed Oct. 15, 1936, on which the present device constitutes an improvement.

An important object of the present invention is to provide, in a concealed hinge particularly for automobile doors and including a pivotally mounted supporting member on which the door is slidably mounted, together with a toggle for actuating the door on said supporting member, new and novel means for connecting said toggle to said supporting member for actuation thereby.

Another important object of the invention is to provide a novel construction and arrangement of supporting member, toggle etc.

Other objects of the invention are to provide a concealed hinge particularly for automobile doors which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured and installed at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in front elevation, showing a pair of hinges constructed in accordance with this invention installed with a door mounted thereon, said door being shown in open position.

Figure 2 is a horizontal sectional view through an upper portion of the invention, showing the door in closed position.

Figure 3 is a horizontal sectional view substantially similar to Figure 2 but showing the door in open position.

Figure 4 is a view in vertical section, taken substantially on the line 44 of Figure 2.

Figure 5 is a view in front elevation of the invention with the door in open position and the panel removed therefrom, the stop bolts being shown in cross section.

Figure 6 is a view in horizontal section, taken substantially on the line 66 of Figure 4 with the pin omitted.

Figure '7 is a detail view in perspective of the toggle.

Figure 8 is a detail view in perspective of the door supporting member.

Figure 9 is a detail view in perspective of the pin which connects the toggle to the door supporting member.

Figure 10 is a view in horizontal section through the upper portion of a slightly modified form of the invention, showing the door in closed position.

Figure 11 is a horizontal sectional View through the modification substantially similar to Figure 10 but with the door in open position.

Referring now to the drawings in detail, it will be seen that the reference numeral I designates an automobile body and 2 is a door of the vehicle. The opening 3 in the body I which accommodates the door 2 has formed therein a chamber 4 in which vertically spaced, horizontal plates 5 are rigidly secured in any suitable manner.

It will be observed that the plates 5 are spaced from the top and bottom of the chamber 4 and said plates have formed therein vertically aligned cam slots 6 of substantially the shape seen in Figure 6 of the drawings.

Extending into the vehicle door 2 from the hinged end thereof is an elongated pocket 1 which is adapted to slidably receive the free end portion of a supporting member 8. The supporting member 8 comprises duplicate angular legs 9 having their free ends hingedly secured to the outer side wall of the chamber 4 in the body I, as at H]. The legs 9 are disposed one above the other in a manner to provide a space H therebetween. Longitudinal slots [2 are provided in the member 8, said slots accommodating stop bolts or the like i3 which are mounted in the door 2. Vertically aligned elongated guides l4 are provided on the pivoted end of the member 8.

The reference numeral l5 designates generally a toggle which is operable in the space I I between the angular legs 9 of the supporting member 8. The toggle I5 includes hingedly connected sections "5 and I1, the latter having one end also pivotally secured to the outer side wall of the chamber 4 at H). The section l6 of the toggle I5 is hingedly connected to the adjacent end of the vehicle door 2 through the medium of a plate l8 which is recessed in said door and secured thereto. Projecting from the section I! of the toggle I5 is an elongated guide l9 which extends at an angle relative to the guides l4 of the member 8.

The reference numeral designates a connecting pin which is adapted to travel in the cam slots 6 of the plates 5, said pin passing through the guides 14 and I9 of the member 8 and the toggle I5, respectively. It may be well to here state that the pin 20 connects the toggle [5 to the door supporting member 8 for actuation thereby. The pin 20 is provided with a head 2! on its upper end which rests on the upper plate 5.

Briefly, the operation of my improved hinge is substantially as f0llows:-

When the vehicle door 2 starts to move toward open position, the member 8 on which said door is slidably mounted, swings in a horizontal plane on its pivot ll]. This causes the pin 20 to travel in the cam slots 6 of the plates 5 and in the guides M of the member 8 in a manner which is thought to be obvious. Movement of the pin 20 in this manner actuates the toggle id for causing the door 2 to slide outwardly on the support 8 as said door opens to .allow for the usual curve or bulge of the vehicle body and door, as shown in Figure 10f the drawings. During this operation the pin 25 also moves longituo- I dinally in the guide IQ of the toggle 15. In the arrangement shown in Figure l of the drawings, two of the hinges constituting the present invention are provided for the vehicle door. Of

course, when the door is swung to closed position the above described operation of the elements 8,

I5, 20, etc., is reversed.

In the modification shown in Figures 10 and 11 of the drawings, the toggle l5 comprises a section 22 which is pivotally secured to the outer side wall of the chamber 4 in the body I. The section 22 includes an angular intermediate portion 23 having mounted thereon in opposed rela tion thereto a complemental angular bar 24. The bar 24 and the portion 23 of the toggle section 22 provide, in conjunction with each other, a guide on said toggle in which the pin 20 is operable. The operation of the modification shown in Figures 10 .and 11 is similar to that hereinbefore described for the embodiment shown in Figures 1 to 9, inclusive, of the drawings.

It is believed that the many advantages of a hinge constructed in accordance with the present invention will be readily understood and although preferred embodiments of the device are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.
