8 Claims.

This invention relates to improvements in brace means for pivoted closures, and more particularly to self-acting brace means for closures of the nature of doors, box lids, rumble seat covers, and substantially any type of closure commonly hinged along one side thereof, and which it might be desired to brace in open position, although the invention may have other uses and purposes as will be apparent to one skilled in the art.

I am aware that in the past many and various types of collapsible brace means have been developed for holding a hinged closure in open position. Frequently, however, it is desirable to both open and close a hinged door or the like, have it braced while in open position, and still have one hand free for other duties. In other words, it is desirable to be able to both open the door and close the door, using only one handfor each operation. In all of the heretofore known brace constructions of which I am aware, it was necessary to use two hands, one to operate the closure member itself and the other hand to effect a releasing of the brace to move the closure into closed position, and in some instances it was also necessary to use the other hand to position the brace in operative position when the door was opened.

In addition, these formerly known brace constructions were frequently cumbersome, dicult to install neatly and inconspicuously, and in Y many cases involved a great number of parts with 'consequent expense in construction.

With the foregoing in mind, it is an important object of the present invention to provide brace means for a pivoted closure arranged for automatic movement into bracing position upon the opening of the closure, there being no adjustment necessary to cause the brace means to act upon the opening movement of the closure.

Another object of this invention is the provision .of brace means for a pivoted closure which means may be controlled by the handle of the closure, the brace means automatically assuming bracing position upon an opening movement of the closure and being released by a normal movement of the closure handle.

A furtherobject of the invention is the provision of brace means associated with a pivoted closure, which brace means are releasable upon a movement of the closure handle towards the shut position of the closure.

It is also an object of `this invention to provide novel brace means for a pivoted door or the like, which brace means are responsive to a movement of the door handle to permit closing of the door, and which brace means automatically assume bracing position upon the opening of the door, without any interference with the ordinary latching means which may be associated for op- 5 eration by the handle.

Still another object of the invention resides in the provision of brace means for a pivoted door or the like, which means effectively hold the door in open position and may be released when 1o it is desired to close the door, the arrangement being such that only one hand is necessary to effect an opening or closing of the door.

The invention also contemplates the provision vof brace means of the character set forth and 15 claimed herein which are simple in construction, durable, economical, and which may be readily installed in an inconspicuous position.

While some of the more salient features, characteristics and advantages of the present inven- 20 tion have been above pointed out, others will become apparent from the following disclosures taken in conjunction with the accompanying drawings, in which:

As shown on the drawings:

The illustrated embodiment of this invention is shown in connection with a jamb I0 of any suitable construction dening an opening which may be covered by a suitable closure II, in this instance illustrated as a door hinged to the jamb as indicated at I2. It will be appreciated that the closure II may be in the form of a case lid, a French window, a trap door, a cover for a rumble seat deck, or substantially any form of closure which it may be desired to brace in open position.

I'he door may be provided with a depending flange I3 thereon, as seen plainly in Figure 2, or it may have any other suitable construction to conceal a connection between the door handle and the brace means to be later described herein. In this instance, the door is provided with a suitable form of handle I4 connected to a rotatable shank I5 carrying any desired latching medium, such as the member I6. Rotation of the handle together with the shank I5 moves the latching member to operative or inoperative position in the usual well-known manner.

It will also be noted, with reference to Figures 6 and 7, that the handle is connected to the shank l5 by a pivot pin I 1, permitting the handle t0 pivot relatively to the shank, as indicated by the dotted lines in Figure 6. To one end of the handle, a Bowden wire I8 or the equivalent is connected, this wire being enclosed in a suitable :sheath I9 which extends upwardly through the top of the door II adjacent the handle, along the underside of the door to which it may be secured in any suitable manner, and the other end of the wire is connected to the brace means in a manner to be later described. It is therefore apparent that the door handle I4 may be rotated to release the latching member without in any manner aiecting the brace means. As will more fully appear later herein, the brace means automatically assume bracing position when the door is opened. When it is desired to close the door, the handle is pivoted downwardly, as indicated by the dotted lines in Figure 6, in the direction4 of the closing movement of the door, and a consequent pull upon the Bowden wire I8 eiects a releasing of the brace means, permitting the door to be closed.

With reference to Figures 1, 3 and 4, it will be seen that the jamb i6 is provided with a groove or hollow 26 in which the major portion of the brace means rests when the door is in closed position. It will be appreciated that the door may have a suitable iiange thereon to cover the hollow 2i) when in closed position, such part not being illustrated for the purpose of clarity in` showing the mechanism.

Referring to the structure shown in Figures l to 5, inclusive, it will be seen that the brace means includes a pair of links or arms 2| and 22. These arms are pivotally connected as at 23 near the adjacent ends thereof. However, it will be noted that the pivot connection 23 is not at the ends of the respective arms, but is spaced inwardly from the end of each of the arms. Adjacent the other end thereof, the link 22 is pivoted to the door I I, as indicated at 2d. The opposite end of the link 2l is turned at an oblique angle from the remainder of the link, as indicated at 25, and this portion is pivotal on the shank of a screw 26 or equivalent securing element attached to the jamb I0 below the hollow 20. With this arrangement when the door is moved to the closed position seen in Figure 1, it will be seen that the arm 22 rests within the hollow 20 in the jamb, while the arm 2I is disposed thereadjacent. It will be noted that the pivotal connection 24 between the outer end of the arm 22 and the door II is in the nature of a hollow rivet or the equivalent, as seen clearly in Figures 3 and 4, which gives the adequate space for the arm 22 to overlie the arm 2| when the door is in closed position as seen in Figure 1.

A member 21, bent to dene an oblique angle, is pivotally connected in a bracket 28 carried by the arm 22, as indicated at 29. At one end thereof, this member carries a pin 30, and on the opposite side of the pivot 29 a suitable leaf spring 3| may be disposed between the arm 22 and the member 2l, tending to urge this member outwardly, so that the pin 30 is normally disposed inwardly in the position seen in Figure 3.

With reference more particularly to Figure 2, it will be seen that the outer end of the arm 2l is expanded, as indicated at 32, and provided with a plurality of apertures 33, in any one of which the pin 36 may engage tohold the arms relatively stiff and brace the door II in open position, as seen in Figure 2. The various apertures 33 provide means whereby the door may be held in various selective open positions.

The opposite end of the member 2'I is loosely disposed around the shank of a headed pin 34 extending through the hollow rivet 24. The inner end of this pin is connected to the adjacent end of the aforesaid Bowden wire I8, as seen. in Figures 1, 3 and 4.

The operation of the structure above described is extremely simple and positive. It is simply necessary to grasp the door handle I4, rotate the handle to release the latching member I6 and swing the door to open position. As the pin 39 carried by the inner end of the member 21 reaches the lrst aperture 33 in the arm 2 I., the spring 3l urges this pin into engagement with the aperture, thus locking the arms 2I and 22 in bracing position. This, of course, is automatically accomplish-ed due to the opening movement of the door. If it is desired to have `the door in farther opened position than permitted by the rst aperture 33, it is a simple expedient to pivot the handle I4 as seen in Figure 6, thus causing the Bowden wire I8 to pull in the opposite end of the member 21 against the action of the spring 3| and thus release the pin 30 from engagement in the aperture 33. Immediately upon release of the pin, 'the door may be swung into further opened position, without holding the handle in its pivoted position, and the pin 30 will automatically engage in the next succeeding aperture 33.

When it is desired to move the door to closed position, it is simply necessary to press down on the handle I 4, thus causing it to pivotfand thus releasing the brace mechanism permitting the door to be moved into closed position. It will be noted that in pressing the handle, the handle is pressed towards the closed position of the door or in the same direction the door is designed to move. It will also be appreciated ythat in the event the latching element I6 is not desired, it can very readily be eliminated, and in that event it is simply necessary to grasp the handle and move the door to open position without pivoting or turning the handle in any way whatsover, the brace means automatically assuming bracing position. It is obvious that the entire actuation of the door may be accomplished easily with only one hand of the operator, leaving the operators other hand free for other duties.

In Figures 8 and 9, I have illustrated a somewhat modied form of construction wherein only a single arm brace member is used. The same control mechanism above described, namely, the Bowden wire I8 and it-s association with the door handle I4, are employed and function in the same manner.

A jamb I0 is provided and the ysame door II is hinged in the jamb as indicated at I2. The jamb is provided with a hollow 20a of somewhat different contour than the previously mentioned hollow 2l), as seen best in Figure 8, and the inside portion of this hollow is closed by a plate 35 secured to the jamb.

A brace member of substantially the same character as the `arm 22 above described is pivoted as indicated at 24 by means of a hollow rivet connection to the door I I, and at the other end carries a headed stud 3B slidable in a slot 31 in the plate 35. This brace arm has the member 21 pivoted thereto in the manner above described, this member carrying the pin 30 at one end thereof, and on the other side of the pivot point 29 the leaf spring 3l is disposed to constantly urge the pin inwardly, Through the pivot member 24, a headed pin 34 extends and the inner end of this pin is attached to the aforesaid Bowden wire I8, the operation of the member 21 being the same as above described.

Beneath the slot 31, the plate 35 is provided with a row of apertures 38, in any of which the pin 3d may engage to hold the door in open position. The operation of the door is substantially the same as previously described, in that it is simply necessary to move the door to open position, the arm 22 sliding along the slot 31 until the pin 3c engages in one of the openings 38. If it is desired to have the pin engage in the next succeeding opening, it is simply necessary to pivot the door handle I4, release the pin 30, and then open the door until the pin again falls into the succeeding aperture 38. To close the door, it is simply necessary to move the handle in the direction of the closing movement of the door, causing the handle to pivot and release the pin 3U, and the brace arm 22 will follow the slot 31 in the reverse direction and eventually lie within the hollow 20a when the door is closed. i

From the foregoing, it is apparent that I have provided novel brace means automatically assuming bracing position upon the opening of a closure with which they are associated, and connected to the handle of the closure so that the handle may merely be moved in the direction of yclosing to release the brace means. The door may thereupon be opened, braced in open position, and again closed upon release of the brace means by a simple movement of the door handle, only one hand of the operator being necessary to actuate the door at any time. It will be further appreciated that the brace means are simple in construction, positive in` their action, durable, and may be economically manufactured and installed.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than is necessitated by the prior art.
