3 Claims. (01. 292-58) I This invention relates to a combination shelf and door lock and-the primary object of the invention is in the provision of a device of this character for use especially in womens toilets 5 in department stores, public places and the like as a means of not only locking the toilet while it is being used to insure privacy, but also as a shelf on which women may deposit their purses or other articles carried by them.

10 An important object of the invention is to provide .a device of this character which may be readily applied to the door and which is simple in construction, consisting of comparatively few parts, and thoroughly efiicient and reliable in use 15 and operation.

The invention together with its objects and advantages will be understood from a study of the following description taken in connection with the accompanying drawings wherein:

20 Figure 1 is a fragmentary elevation of a door showing my device mounted thereon with the shelf in its raised position.

Figure 2 is a vertical sectional view taken substantially on the line 2-2 of Figure 1.

Figure 3 is a view similar to Figure 1 showing the shelf in a down position.

Figure 4 is a section taken substantially on the line 4-4 of Figure 3.

Figure 5 is a detail view of the bolt showing 30 the diagonal groove formed therein.

Figure 6 is a view similar to Figure 3 of a slightly modified form of the invention.

Figure 7 is an end elevational view of the structure shown in Figure 6 the raised position of the 35 shelf being suggested by broken lines.

Figure 8 is a view similar to Figure 6 of still another form of the invention, and

Figure 9 is an end view of the structure shown in Figure 8 with certain parts shown in section.

Referring to the drawings by reference numerals it will be seen that 5 indicates a door, the same being shown fragmentarily while 6 indicates the door jamb, the jamb being also shown 45 fragmentarily. On the inside of the jamb 6 there is provided a suitable keeper 1. Mounted on the door 5 at the inside of the door are alined bearings 88, these bearings being shown, alined with the keeper I. A panel 9 is also mounted on the door at the inside thereof and arranged in the panel is a mirror Ill. Projecting from the panel below the mirror is a stud or projection II that projects into a diagonal slot I provided on an intermediate portion of a bolt I2. The

55 bolt l2 has end portions I4I4 slidable and rockable in the bearings 8, and as thought appar- I ent, when the bolt I2 is rocked one end I4 of the bolt is projected into the keeper 1 or retracted therefrom due to the engagement of the projection II with the diagonal slot I5. 5 Formed integral with the bolt I 2 is a shelf I1, and integral with the shelf I! and bolt I2 are stop ribs I6, and as shown in Figure 4 the'ribs I6 are adapted to abut the panel 9 when the shelf I! is in its lowered position, which is of 10 course t e position shown in Figures 3 and 4.

Norma y the shelf is in the raised position shown in Figure 1, and when in this position, the shelf conceals the mirror Ill and the bolt I2 is in a retracted position.

To look the door the occupant of the toilet must pull down on the shelf, and as the shelf swings from the position shown in Figure 2 to the position shown in Figure 4 the bolt I2 is projected into engagement with the keeper I thus automatically locking the door while at the same time providing the occupant with a shelf on which she may place the articles which she has to carry. When the occupant desires to leave the toilet the shelf must be folded up against the door to the 2 position shown in Figure 2 and the swinging movement of the shelf in the position shown in Figure 4 to the position shown in Figure 2 will cause the bolt I2 to be retracted for unlocking the door. The necessity of folding up the shelf will prevent the occupant from forgetting articles and leaving them behind.

In the form of the invention shown in Figures 6 and '7, the keeper I may be dispensed with, and the door 5' being provided on the inside with a knob I8, I propose to provide the knob with a notch I9. In this form of the invention the shelf I1 and the bolt I2 are integral and on the bottom side of the shelf I'I there is provided a depending lug 20 that, when the shelf is folded or 40 swung to the down position shown in Figure 7, will engage in the notch I9 of the knob to thereby lock the door against being opened from either the inside or the outside of the toilet until the shelf 11' is again swung up to its folded position, or to the position suggested by broken lines in Figure '7.

In the form of the invention shown in Figure 8 there is provided on the jamb 6a a keeper plate 22 provided in its upper edge with a vertical notch 23. On the under side of the shelf I'Ia there is provided a lug 2| which is in the form of an arm arranged to engagein the notch 23 of the keeper when the shelf I'Ia is unfolded or swung I down to an operative position. With the lug or arm 2| thus engaged with the plate 22 the door So will be securely locked from the inside.

It will also be noted that in each form of the invention there is provided a suitable spring S engageable with the shelf in a manner to retain the shelf in its raised or inoperative position, and against being accidentally swung downwardly in the event the door is slammed shut upon one leaving the lavatory.

Having thus described my invention, what I claim as new is:

1. A door latch of the class described comprise ing an elongated bolt, bearing members with which the end portions of the bolt engage, a shelf forming member of less length than the bolt and having one edge integrally formed with intermediate portions of the bolt, spring means for normally holding the parts with the shelf forming member in vertical position and a keeper engaging part on the bolt movable into keeper engaging position when the shelf is moved into horizontal position and out of keeper engaging position when the shelf is moved into vertical position.

2. A door bolt of the class described comprising a supporting member adapted to be connected to a door, an elongated horizontally arranged bolt, bearing members receiving end portions oi. the bolt and between which the lower edge of the supporting member is located, a shelf forming member of less length than the bolt and integrally connected at one edge with intermediate portions of the bolt, spring means carried by the supporting member for normally holding the shelf forming member in raised position, said bolt having a substantially spiral groove in an intermediate part thereof and a projection carried by the supporting member and engaging the groove, whereby swinging movement of the shelf-forming member. to its horizontal position will move the bolt and shelf -forming member longitudinally to place an end of the bolt in keeper-engaging position, the upward movement of the shelf-forming member moving the same and the bolt in pposite directions to place said end of the bolt out of keeper engaging position.

3. A door bolt of the class described comprising a supporting member adapted to be connected to a. door, an elongated horizontally arranged bolt, bearing members receiving end portions of the bolt and between which the lower edge of the supporting member is located, a shelf-forming member of less length than the bolt and integrally connected at one edge with intermediate portions of the bolt, spring means carried by the supporting member for normally holding the shelf-formingmember in raised position, said bolt having a substantially spiral groove in an intermediate part thereof and a projection carried by the supporting member and engaging the groove, whereby swinging movement of the shelf-forming member to its horizontal position will move the bolt and shelf-forming member longitudinally to place an end of the bolt in keeper-engaging position, the upward movement of the shelf-forming member moving the same and the bolt in opposite directions to place said end of the bolt out of keeper engaging position, and wings formed on the shelf-forming member and engaging parts -of the supporting member, when the shelf forming member is in horizontal position to limit downward movement of the shelf-forming member.
