Assistant Examiner-Peter A. Aschenbrenner Attorney, Agent, or Firm-Stevens, Davis, Miller & Mosher [57] SCT A detent spring for holding an arm adapted to be moved in a vertical arc and a door stop having the usual pivoting arm in combination with said spring, said spring holding the arm in adjusted positions and holding the arm within a base attached to the lower portion of a door.

7 Claims, 7 Drawing, Figures noon sror It is an object of this invention to provide a simple and efficient structure having a base and swingable member anchored therein by means of a retainer which is secured to one end of said member from the inside of the base, the retainer means also functioning to restrain the free swinging movement of the member.

A further object of the invention is to provide a U- shaped spring adapted for use in a door stop or the like which has its extending arms biased toward each other, the spring being provided with detent means for engaging in slots in the face of a head of the door stop arm and having aligned openings in its extending arms for receiving a fulcrum pin to secure the arm to the spring.

A still further object of this invention is to provide a door stop having a mounting bracket through which the head of a swingable arm may be passed for the application of a U-shaped spring thereto, the spring engaging said head and being pivotally connected thereto. According to the invention the pivotal connection is preferably formed by a fulcrum pin extending through openings in the spring arms and an opening in the head, the spring being received in accommodating recesses within the base and being secured against removal therefrom when the base is secured to a door.

Further objects and advantages will be apparent from the following detailed description when viewed in connection with the accompanying drawings in which:

FIG. I is a perspective view of a door stop made in accordance with this invention illustrating its esthetic appeal when attached to the lower portion of a door;

FIG. 2 is a side view of the stop illustrated in FIG. 1, it being partially broken away to expose the head of the swingable arm as retained therein, the Figure illustrating the respective positions to which the arm may be adjusted, together with the detent and radially arranged slots for holding the arm in the desired positions;

FIG. 3 is a sectional view taken along the line 3-3 of FIG. 2;

FIG. 4 is a view of the open end of the bracket of the device shown in FIG. 1 with the retaining mechanism mounted therein;

FIG. 5 is a perspective exploded view of the bracket, the swingable arm, the novel spring and the fulcrum pin adapted for securing the spring and the head of the arm together;

FIG. 6 is a modified form of a spring usable in this combination, and

FIG. 7 is a view of the open end of the bracket with the modified spring in position.

In referring to the drawings in detail, a bracket is shown at It). It is formed with a base ll which is recessed on its under side as at 12 to provide a marginal flange 13 which tits snugly against a door 14, to which it is held, when affixed, by means of corner screws 15. Base ll inwardly of marginal flange 13 is provided with an opening 16 extending to the front of bracket 10. Along each longitudinal edge of the opening 16 on the front of bracket 10, wings 17 are provided to form a continuance of the sides of the passageway. The outer edges of the wings are flush with the longitudinal outer edges of base ll and the base, together with wings 17, each have along their internal walls recesses 18 adapted to receive extending arms 19 of U-shaped spring 20, spring 20 receiving between its arms 19 and the head 21 of swingable arm 22, which head is of a size which is receivable in and will pass through the opening 16 in the base. Arms 19 are provided with aligned openings 23 for receiving a fulcrum pin 24 which pin is passed through the opening 23 and the opening 25 within the head of the swingable arm 22, thereby connecting the spring and the swingable arm together.

The arms 19 of spring 20 are biased toward each other and are provided with inwardly struck detents 26. Due to the bias of the spring arms 19 the respective detents are receivable in respective corresponding radially arranged elongated notches 27 corresponding sets being provided in each face of the head 21. When the spring 20 is assembled with the head 21 and the fulcrum pin 24 in position, the swingable arm 22 is drawn forwardly in the base ill with the spring 20 lying within recesses 18. The fulcrum pin 24 is thus moved into its operative position within respective recesses 28 which are narrower and deeper than recesses 18, thereby securing the fulcrum pin against accidental displacement.

Spring 20 has near the base of its arms 19 projections 29 which bear tightly against the bases of the recesses 28 and tend to retain the assembly in the upward part of bracket 10 and to generally assist in biasing arms 19 of spring 20 toward each other. Spring 20, however, is otherwise formed to also have the arms 19 so biased. After swingable arm 22 has been assembled and moved into position within bracket 10, the unit is applied to a door by the mounting screws 15 as aforesaid, and spring 20 will be retained in its position within the recesses 18 since the door provides a. closure for the open end of the bracket.

When the unit is assembled, downward movement of swingable arm 22 will engage foot 30 with the floor so that the door will be limited in movement in the nature of door stops with these characteristics as known in the art. In this position, the detents 26 are received in the corresponding notches 27A. When it is desired to use the unit as a bumper for preventing the door from marring an adjacent wall section, swingable arm 22 is moved upwardly to a horizontal position, whereby the foot 30 extends outwardly. In this position, detents 26 are received within notches 27B. When it is desired to move the swingable arm 22 to an inoperative, out of the way, position, it is swung upwardly parallel to the face of the door and when it is in this position detents 26 are received in notches 27C.

In the modified form of spring 20' illustrated in FIG. 6, only one of its arms, namely 19, is provided with a detent as illustrated at 26', while a projection 29' is provided in each arm for engaging in the walls of recesses 18'.

The spring illustrated in FIG. 6 is adapted to be attached to the head of the swingable arm by means of fulcrum pin 24'. The manner of mounting the spring shown in FIG. 6 is illustrated in FIG. 7 which shows the open end of the bracket with the spring 20' therein.

What is claimed is:

I. A door stop comprising:

a. a swingable arm moveable to a plurality of positions having a hub at one end. for pivoting of the arm;

b. a bracket for securing to a door having an interior cavity holding said hub with a front opening dimensioned to permit said hub to pass therethrough, said front opening being of smaller width than the cavity to present an abutment shoulder adjacent the front opening;

c. connection means providing both a means for retaining and pivoting said hub in said cavity, said connection means comprising:

1. fulcrum means for said hub;

2. U shaped spring means having arms which contact the hub and have means to engage said fulcrum to prevent said spring means from being pulled outwardly from the fulcrum;

3. at least one dimension of the connection means being greater than the distance from said abutment shoulder to the opposite side of the cavity so that after the spring has been engaged with the fulcrum means from the back of the cavity, the hub cannot be withdrawn from said front openmg.

2. The door stop of claim 1 in which the means to engage said fulcrum means is an opening in the hub and an arm of the spring with a fulcrum pin passing through 6. The door stop of claim 1 in which the hub has at least one flat face which is engaged by an arm of said spring, the face having at least one detent means and the engaging arm having a corresponding detent means.

7. The door stop of claim 1 including an outwardly projecting portion on said spring arm for engaging an adjacent wall of said cavity.
