2 Claims. (01. 292-278) This invention relates to improvements in overi head door holders. The object of the invention is to provide a telescopic door holder in which all the operating parts are concealed and which is free from all projecting arms, handles, brackets and like parts, which constitute elements of construction in prior devices.

One object is to provide a door holder which may be so mounted and is so arranged that its outer free end may be secured relatively close to the free edge of the door whereby to provide maximum holdirigpower with the parts of the door holder in a single straight line andwhereby to eliminate strains on the door hinges. Still another feature relates to the ease with which the door holder may be so mounted so as to be practically invisible. Another distinguishing feature is the very simple means whereby the holding lock or catch may be controlled to function actively or inactively. Other novel features will be'pointed out as this specification proceeds.

Accordingly the invention is embodied in an overhead door holder arranged and constructed as hereinafter set forth and as illustrated in the accompanying drawings in which Fig. 1 is a sectional view of the door holder with parts broken away and showing the operating mechanism in non-holding position.

Fig. 2 is a similar view showing the holder in locked or door holding position.

Fig. 3 is a similar view but shows the parts in position at the moment of release of the holding means.

Fig. 4 is a side view with parts in section looking in the direction of the arrow 4 in Fig. 1.

Fig. 5 shows the door holder applied to a door with the latter held in open position.

Fig. 6 is a perspective view showing the door holder mounted as a concealed door holder.

The door holder according to this invention comprises two arms mounted in sliding telescopic relation. The outer arm [0 slides within the inner arm II. The outer arm is adapted to be pivoted on the door 12 near the free edge thereof by means of a suitable bracket or mounting I3, Fig. 5. The inner arm II is pivoted to the overhead frame of the door casing M by means of another suitable pivotal mounting 15. The two arms are preferably of rectangular cross section.

The inner arm ll carries a slidably mounted controller [6 operable from the outside of the holder by a thumb piece I! which slides in a cut out [8 in the arm so that the controller may be moved manually into one of two distinct positions to control the operation of the holding catch or hook. The arm II also carries a fixed catch 19 secured by a screw 20.

'The outer arm lllhas a closed end 2| which receives a block 22. The latter contains a cushioning spring 23 which acts against the heel 24 of a hooked trigger 25. 1 Another spring 26 engages the heel on the other side thereof. The other end of the spring 26 is held in position by an abutment 21 which is held by the spring against the edge '28 of a cut out 29 in the outer arm.

I The action of the two springs is such that the hook 30 of the trigger is forced outwards through an opening 3| in the outer arm II] so that said hook will automatically engage the catch 19 when the door is to be locked in open position as will be explained later. The spring 23 serves takes place.

to cushion and ease the operation of the trigger and also serves as a pivotal support.

The movement of the trigger outwardly through regulated by means of an adjustment 32 which is movably supported on an adjusting screw 33. The adjustment engages the inclined surface of the hook and acts as a stop. When the adjustment islowered on the screw 33 theoutward movement of the trigger is correspondingly lessened.

When the door swings open the inner arm ll swings outward about its fixed pivot 35 and the pivot 36 of the outer arm I!) swings outward. The outer arm then slides out from the inner arm. When the door closes the reverse action Thus while the door swings freely back and forth the outer arm slides in and out of the inner arm. The positions of the parts in the door holding. mechanism during the free movements of the door are shown in Fig. 1. In this view the controller I6 is moved to engage the catch I9 so that, as the arm I0 slides outward in the arm II, the hook 30 cannot engage the catch. During such outward sliding movement of the arm II] the catch merely slides in under the catch I9 and remains slightly depressed as it moves further under the catch and under the controller [6. The parts are so arranged, the extreme distance between the

pivots

35 and 36 being fixed, that the arm 10 never slides completely out from the arm I l and the hook 30 never passes outwardly from under the controller 16. During the telescoping movements of the two arms the parts are in the positions shown in Fig. 1, the hook 311 having been moved outward through the opening 3| as it passes from under the catch.

When the door is to be held in open position, the controller [6 is moved outward from the position in Fig. 1 to the position in Fig. 2 thereby providing a space between the controller and the catch I9. Hence, when the hook 30 reaches this point it will snap up in front of the catch. Now the arm I cannot be moved into the arm I l and the door. is. firmly locked and, held in open position, Fig. 5. 1 r I In order to close the door after the door holder has been locked pressure is applied to the. outer edge of the door.

Thus the distance be tween the

pivots

35 and 36 is slightly increased and the arm l0 pulled out furthenirom the arm v The hook 30 is thereby'moved awa'yirom" the catch l9 and moves in under the controller l6, the latter being then in the .position'shown in ;i1

Fig. 2. It is now possible to move the controller back against the catch l9 as shown in Fig. 3"a'nd' close the space where, the hook would otherwise engage the catch. As the pressure upon the door is released, the doorgwill swing back and close-andtheholder will telescope. It will be noted that the spring 26 is 'a' very strong spring so that normal -r'unning againstthe door'or normal pushing against it is not sufiicient to compress the spring so that the holder maybe accidentally unlocked and the door closed when it should be held open. It is also to be noted that eventhough the door should' be accidentally pushed open beyond its normal open position the door holder will not be unlocked because the controller will in such case'not be in position to prevent the hook from engaging the catch as soon as such accidental pressure is released. The holder is unlocked only'by causing the outer arm to move slightlyoutward beyondlocked position and then move theco'ntroller to engage the catch. It will be observed that this operation is very simple and does not require the turning of handles, forcible unlocking of bolts or other parts such as is required with many prior devices. I

Normally the controllerwill be'in the position shown in Fig. 1 and the door holder will then swing freely with the movements of the door. The controller may at any time be moved away from the catch and then the door holderwill lock automatically when the door is fully opened. Unlocking of the door holder is done by extendingthe holder slightly to disengage 'the hook from the catch and then move the controller to prevent reengagement. p i

The adjustment 32 regulates the movement of the hook across the arm 10. When the holder is fully extended the screw 33 is accessible for slam. This is an obvious advantage in case of emergencies.

The invention therefor includes means to unlock the holder by applying a slight i excess pressure to extend the holder and then aoperate the controller, as well as means for 15- iorcibly breaking the look by abnormal force in the opposite direction.

Fig. 6 illustrates how the door holder may be mounted as a concealed door holder. In this case the pivot 35 of the inner arm is moved nearer the edge of the door frame M. The door is mortised as at 40 and the pivot 36 placed in the mortise. When the door is closed the holder will telescope within the mortise 40. It will not be'visible from the outside of the door and from the inside the holder will appear merely as a countersunk or set-in piece or bar.

The door holder as herein disclosed is adapted tofit all sizes of doors. Because of the absence of inter-pivoted arms or links which include toggle action such as is common in many prior devices there isno strain on the door hinges. The door holder has a, pleasing inconspicuous appearance. All the'operating parts are enclosed and thus protected against dirt. The only manual operation required besides applying pressure upon the door is the easy movement of the controller,

We claim: 1

1. A door holder comprising a pair of hollow arms in telescopic slidable relation, a fixed catch within one of said arms, a movable trigger within the other arm adapted to engage said fixed catch to lock the said two arms in extended door holding positionga movable controller within the said one arm, a thumb piece for positioning said controller to normally prevent the said trigger from engaging the fixed catch and for positioning said controller to permit said trigger to engage said catchto lock-the said arms in extended door holding position.

2. A door holder according to claim 1 including means for regulating the movement of the movable trigger. W V
