DOOR STOP AND HOLDER Harry Bontempo, Hollywood, Calif. Application November 30, 1953, Serial No. 394,962

1 Claim. (Cl. 292-216) This invention refers to building hardware and more particularly to that class of equipment known as door stops. In this type the door stop involved embodies a lock for holding the door stationary whenever it is operated, and yet it can be readily unlocked by akicking blow of the user.

In this invention, the device consists of two main members. They are fastened to the floor by screws or nails and are allowed a certain amount of rotation thereon for operating purposes. The device locks the door when its edge engages with one member of the lock and swings it so that it revolves the second member and the latter interlocks in it, when it does the former cannot of itself unopen. The operator easily releases the members by striking the second member with his foot. This moves it away from its locked engagement with the first member and also moves the door into a released position.

For a clearer understanding of the invention, its objects and principles, reference is made to the drawings. These drawings together with the following description indicate a particular form of the invention. This is done by way of example, not as a limitation of the construction of the invention, while the claims show the scope of the invention.

In the drawings:

Figure l is a plan view of the stop-lock embodying this invention in a position for holding the door;

Figure 2 is a similar view to that shown in Figure 1 except the stop-lock is released to allow the door to be closed;

Figure 3 is an enlarged detail of the stop lock in full lines when holding the door open and dotted to show its position when the door is released;

Figure 4 is a side view of Figure 3 looking from the left side thereof;

Figure 5 is a side view of Figure 3, looking from the right side thereof; and

Figure 6 is a side view of Figure 5, looking from the bottom side thereof.

Similar reference characters relate to the same parts throughout the drawings.

In the construction shown, a door lock-stop includes two members 10 and 20 respectively. They are flat on their upper and lower sides. The first member is termed the handle and includes an arm 11 which extends from a head 12 having a 6-like contour. The semi-circular rounded portion of the contour has a hole 13 through which a fastening screw 14 is used to hold the member pivoted to the floor. It is flattened at 18 between the portion 15 and the pointed portion 16, with an arcuate back 17 formed at the rear, all as shown in the drawings. It will be noted that the location of the screw 14 is eccentrically located with respect to the rounded portion 15.

The second member 20 is termed the channel and is recessed on one side to form a Ulike slot 24 in which a door edge 21 can fit. The flanges 22 and 23 respectively are positioned at the ends to the slot 24 and are rounded to facilitate their contacts with the door edge. The upper flange 22 is longer than the lower flange 23. The back of the channel is formed in the contour indicated in the figures. The inside wall of the channel slot 24 is slightly bent out of line particularly where the inner edge of the door 21 rubs during its opening and closing. The head 12 of the handle fits into a semi-circular slot 25 in the member 20 and rotates partially in it, both members being positioned in the same flat plane. The

2,693,976 Patented Nov; 9, 1954 slotf 25 ismade in the member 20 by extending flange 22jbac'kwardly and angularly to meet the face 18 with asquare' face 26. A hole 27 positioned in the member 20 serves for the placement of a fastening screw 28 therein. A hump 29 is formed at the back of the member 20 to provide the material in which the slot 25 is cut.

While the member 10 is rotatable about the screw 14, the member 20 is rotatable about the screw 28. The two pivot points 14 and 28 are both oflset along vertical and horizontal axes passing therethrough. The hump 29 terminates in a lower sharp point which limits the movement of the handle 11 from the dotted line position thereof to the full line position in Figure 3.

The operation of the device will bring out the features of the structure and their purposes more clearly. The unit is located close to the wall 30 of the building against which the door 21 is swung, by means of the screws 14 and 28. This places the members 10 and 20 in proper operative relation so that they revolve in one another on the floor as explained subsequently. When the door is closed against the stop lock the edge of the door passes by the flange 23 and sequentially strikes flange 22 the flange 22 is struck so as to revolve on its screw 28 and bring the flange 23 against the door and embrace its edge portion. At the same time, the face 26 pushes against the face 18 of the head 12 and forces the handle 11 on its pivot 14 to assume the position shown in Figure 1. This looks the stop-lock. Pulling on the door will induce it to hold tighter, since such pulling tends to rotate the channel clockwise, causing the hump 29 with its point 40 to bind against the rounded portion 15 at its connection with the handle 11. This occurs because of the fact that the point 40 is on a vertical axis to the right of the vertical axis passing through the screw or pivot 14, so that the door is firmly held in place, while in the device as described. However the unlocking of the device is simple, effective and expeditious. This is brought about by the kicking of the handle arm 11 towards the wall. This rotates the handle, until the faces 18, 26 meet one another to rotate the channel to its open position, as shown in Figure 2. This positioning pushes the door 21 outwardly by the pressure of the flange 22 without the flange 23 obstructing its movement. The door can then be swung closed.

The device takes up little room since its greatest dimension depends only on the thickness of the door. It has an attractive appearance. It consists of only two parts, ignoring the fastening screws, and is of rugged structure. As a lock it is very eifective, yet for unloosening requires little effort and no tools. It works automatically for locking and opening. It is quickly installed at little expense and has no concealed parts that could require attention. There are no springs, which is very important as such have a tendency to break at inopportune times. Its operation may be observed at all times.

While but one general form of the invention is shown in the drawings and described in the specifications, it is not desired to limit this application for patent to this particular form as it is appreciated that other forms of construction could be made that would use the same principles and come within the scope of the appended claim.

Having thus described the invention, what is claimed is:

A lock-stop for a door comprising two separate flat members, the first of said members having a semi-circular portion, a pivot for said portion eccentrically located therein, said first member also having an arcuate back portion oppositely disposed with regard to the semi-circular portion, a handle connecting and extending outwardly from said semi-circular and arcuate portions, the arcuate portion having an extension connected with the semi-circular portion by a flat surface, the second of said members being generally U-shaped to form a channel between its legs to receive the door when in open posi tion, a pivot for said second portion offset from the first mentioned pivot, the channel being disposed outwardly of the pivot for the second member, said second member having a concave surface between the two pivots receiving the semi-circular portion of the first member and a hump extending toward said semi-circular portion, the junction of the hump and concave surface forming a point in binding contact with the aforesaid semi-circular portion,
