4 Claims.

10 overhead door holder with an improved cushioned latch to take care of strains and pressure on the operating arms.

Another object is to provide an overhead door holder adapted for mounting on the outswinging 15 side of a door.

Still another object is to improve the mechanism for operating the latch which locks the holder when the door is open. Other objects will appear as this specification proceeds. Accordingly the invention is embodied in an overhead door holder arranged and constructed as hereinafter set forth while reference is had to the accompanying drawings in which Fig. 1 is a perspective view showing the door 25 holder in position with the door open.

Fig. 2 is a plan View showing the holder in different positions.

Fig. 3 is an enlarged view of the holder as it appears when the door is closed, parts being .30 broken away.

Fig. 4 is a sectional view of the latch mechanism taken on line 4-4 of Fig. 3.

Fig. 5 shows a modified detail.

Fig. 6 is a view of the door holder mounted .35 on the outside of a door.

Fig. 7 is a plan view of Figure 6 showing the door open.

Fig. 8 is a detail of a modified latch mechanism.

Referring now to the drawings the door holder -r 40 comprises two

arms

10 and 11 pivoted together at 12. The inner end of the arm 10 is pivoted to a bracket 13 secured to the crown sill 14 of a door casing or the like. The outer end of the arm 11 is pivoted at 15 to a bracket 16 secured to the The arm is formed with a horn or offset portion 26 having a hole 18 adapted to be engaged by a latch mechanism 17 on the bracket 16.

As best seen in Figure 4, the latch mechanism comprises a latch bolt 19 movably mounted with- 50 in a cylinder 20 and urged upwardly by a spring 21. The bolt has a head with an inclined upper surface 22. Below the cylinder there is attached a handle 23 to the bolt which also carries a pin 24. The hole 18 in the arm 11 is adapted to slide 155 in over the head of the latch bolt into the position shown in Figure 4, depressing the bolt which thereupon snaps upwards into the hole 18 under the influence of the spring 21 and thus forms a positive stop against accidental outward movement of the arm 11. In other words when the arm 11 has engaged the latch, the door holder is latched.

The door holder is unlatched by taking hold of the handle 23 and turning the bolt. The pin 24 then rides downward on a cam surface 25 on the cylinder 20 and thus causes the bolt to be withdrawn from the hole' 18 in the arm 11 whereupon the door may be closed.

The latch is then again put in position for automatic engagement with the arm ll by simply turning the bolt so that the pin 24. can ride up on the cam surface 25 and the spring 21 forces the bolt upward into operatingposition. I

While the doorholder is latched with the door in open position it happens that accidental strains are put upon the mechanism by persons pressing against the door. Such strains or pressure if not otherwise provided for may cause breakage or shearing 01f of the screws for securing the brackets l3 and 16. To overcome this trouble the latch mechanism includes a cushion member 27 in the form of a button or cap backed by a spring 28, see Figure 4. The button is held in normal engagement with the horn 26 by means of the spring. When extra pressure is put upon the door, the pressure is taken up by the spring 28, the horn depressing the button in an obvious manner. In other words there has been provided a cushioning member between the door and the one arm of the doorholder to permit of an extra movement or play in the device when abnormal or accidental extra pressure is exerted upon the door.

In case where an absolutely locked or latched doorholder is not necessary, the head of the bolt 19 may be shaped as in Figure 5 in which case the bolt acts as a spring pressed button 30 which holds the doorholder in open position under ordinary conditions but which permits closing the door by a strong pressure thereon. In such case the hole 31 in the arm 11 is shaped to correspond.

In addition it may be shaped in both sides of the arm so as to be used in both a right hand and a left hand doorholder.

Figures 6 and '7 show the doorholder mounted on the outside of a door. In this case the doorholder as described above is reversed and turned upside down. The bracket 16 with the latch mechanism is mounted on the door casing 35 and the long arm 10 is pivoted to the door 36 by means of a special bracket 37 permitting movement of the arm in a plane above the door. The release of the latch bolt may be done as above described by merely operating the handle 23 but where this is inconvenient as for instance where the door is of an unusual height the latch bolt may be withdrawn from engagement with the offset arm 11 by means of a chain 38 passing over pulleys 39. Thus remote operating means is provided. The operator will of course maintain a pull on the chain long enough to permit the arm 11 to be swung away from the bolt.

Figure 8 shows the latch bolt provided. with a head 40 adapted to be operated by a special key or wrench 41. This is a desirable feature where it is desired to prevent unauthorized unlatching of the door holder. The key 41 may of course be of any suitable length. It will also be understood that the latch bolt in Figure 3 may have a long stem whereby to position the handle 23 within convenient reach. This is of course only possible in cases where the latch mechanism is mounted close to the door so as to be out or" the way.

The doorholder according to this invention possesses several advantages over the prior art as above set forth. It provides for safer and more efficient operation and greater adaptability.

I claim:

1. A door holder comprising a pair of pivotally connected arms, means for pivotally connecting the free end of the one arm to the door frame, means for pivotally connecting the other arm to a door, latching means on the door adapted to engage said other arm automatically when the door is swung open to maintain it in open position and cushioning means between said other arm and the door operable when the door is open.

2. A door holder comprising a pair of pivotally connected arms, means for pivotally connecting the free end of the one arm with the door frame,

means for pivotally connecting the free end of the other arm with the door, a spring pressed bolt on the door adapted to engage an aperture in said other arm automatically, when the door is swung open, a spring pressed button mounted adjacent said spring pressed bolt and adapted to engage a portion of said other arm to serve as a cushion between the latter and the door when the latter is in open position.

3. A door holder comprising a pair of pivotally connected arms, means for pivotally connecting the free end of the one arm with the door frame, means for pivotally connecting the free end of the other arm with the door, said other arm having a horn shaped portion adjacent its pivotal connection with the door, a spring pressed bolt on the door adapted to engage automatically an aperture in said-horn shaped portion when the door is swung open and a resiliently mounted member on the door adapted to engage the end of said horn shaped portion, said member serving as a cushion between said other arm and the door.

4. A door holder comprising a pair of pivotally connected arms, means for pivotally connecting the free end of the one arm with the door frame, means for pivotally connecting the free end of the other arm with the door, said other arm having a horn shaped portion adjacent its pivotal con nection with the door, a bracket secured to the door, a vertically disposed spring pressed bolt in said bracket adapted to automatically engage an aperture in said horn shaped portion when the door is swun open and a horizontally disposed spring pressed button in said bracket adapted to engage the end of said horn shaped portion to serve as a cushion between the said other'arm and the door when the latter is open.
