HOLDER FOR CLOSURES, SUCH AS LIDS, SASHES, DOORS, AND THE LIKE.

Application filed May 25,

y My invention relates to a holder for closures, such as lids, sashes, doors and the hke; wherein the closure is movably associated with its cooperating structure, and which may or may not be hingedly attached thereto by means independent of the holder.

An object of the invention is to provide a holder which will positively limit the movement of the closure outwardly with respect to its cooperating structure and maintain it in outward or open position, and which is semi-automatic and positive in its locking and releasing action; and such a holder which is of a simple construction and readily adapted to economical production.-

Another and a more specific object is to provide such a holder for use in connection with cabinets, such for example as those containing talking machines; but it is to be understood that the scope of usefulness of my invention is to be as broad as heretofore pointed out.

Numerous devices of this general character have been heretofore disclosed and some of these have been used in practice; but none of these devices has provided a closure means which is positive in its locking and unlocking action and which adequately fulfills the demands for such an article. Furthermore, many of these devices are cumbersome, and the cost of manufacturing the same is prohibitive for this class of article.

l In my invention I provide an article which is excellently adapted for economical production, and which is neat in appearance, small in dimensions and light in weight. In general, my device comprises a longitudinal arm which is adapted to be pivotally attached to a closure means adapted for cooperative association witha stud attached to the body carrying the closure means. Upon lifting the closure means, or moving it outwardly with respect to the associated body member carry-v ing the stud, the stud slides outwardly along the arm until it strikes the positive stop forming a part of the arm, and if then the closure means is released, it is held in fixed spaced relation with respect to the body. This action is positive both as to the stopaction and the locking action. When it is desired to lower or shut the closure means, the closure is raised slightly from its locked position and then lowered; this action causing a positive unlocking of the studand allowing it to be 1927. serial N0. 193,968.

returned along the arm, to thereby allow the closure means to return toits closed position. Alternatively, the arm may be carried on the relatively fixed body, and the stud carried on the closure means as is obvious to those skilled in the art. While the device is primarily adapted to be used on that form of closure means, commonly termed a lid, and which is adapted to be raised and lowered to its respective open and closed position, nevertheless it is also adapted to be used on closures positioned otherwise, as will be more fully pointed out following. It is also adapted to be used on closure means which 'are not independently hingedly connected to an associated body.

My invention consists in the novel construction, arrangement and combination of parts hereinafter described according to a preferred embodiment thereof. The invention will be more particularly pointed out in the appended claims.

Other objects, features and advantages will appear from the following specification and claims taken in connection with the accompanying drawings.

Referring to the drawings illustrating the present preferred form of the invention:

Fig. 4 isa section at 4-4 of Fig. 2,

Fig. 5 shows a portion of the holder embodying a modification of the latching mechanism, and

Fig. 6 shows a different position of the modification shown in Fig. 5.

Referring to the'drawings: 1 represents a cabinet, such for example as a talking machine cabinet, having a lid 2; such cabinet and lid being representative of a structure comprising a relatively fixed member and a movable member, and in which the movable member will be referred to generally as a closure. 3 represents a projection, such as a whichit may be die stamped with ease. rllhe arm 4'is provided with a longitudinal slot 6 which terminates adjacent the outer end of the arm in an enlarged recess or opening 7. This opening 7 is formed with an upwardly and outwardly inclined wall portion lformed as a continuation of the upper wall of slot 6 and which terminates at 8 inthe form `of a pocket. The lower wall of slot6 continues outwardly and terminates in a recess 9 which serves as a seat forI engaging the stud 3. A lip 10 is provided between the pocket 8 ,andy seat 9 forming thereby a reentrant portion extending within the recess 7 and provided l with a downwardly inclined inner face. The

Alatch 11 is pivotally supported within the recess 7 on the pivot 12 which is carried by the extension 13. rll`he extension 13 is preferably formed asa part of the stamping comprising the arm 4 in the manner indicated in dotted lines in Figs. 2 and 4, which indicate the position which vthis extension occupies in the flat pattern in the stamping. After the stamping is made, this part isbent up as shown in Figs. 2 and 4 and the `pivot 12,

'which is formedas a part of the extension 13 is bent inwardly and lies within the recess 7. rllhe latch11 is provided with a tail portion extending inwardly from the end of the arm, and with a head portion extending outwardly toward the end of the arm. The head portion is provided with a recess 14 in which the stud is' adapted to be seated during the locked position of the holder. The lower surface of the latch 11 tapers downwardly and between its lower outward edge and .the recess 14 is formed a detent 15; the. outer edge of this detent being spaced inwardly from the lip 10. The upper edge of the latch 11 projects outwardly near the recess 14 and is provided with a nose 16 which extends adjacent the upper edge of the inclined face of the lip 10. The latch 11 is normally yieldably positionedas shown in Fig. 2, by suitable means such as the spring 17, so thati the nose 16 lies closely adjacent to the lip 10; and in this position of the lid 11 the extreme inwardly extending tail of the latch lies adjacent the juncture between the slot 6 and the recess 7. In this position the lower edge of the latch in combination with the upper wall of the slot 6 forms in 'effect a track upon which the stud 3 is adapted to slide in its outward movement with respect to the arm. Also in the maal-iii Uperatz'a.

With the various members and parts as shown in Figs. 1 and 2, upon raising the lid or closure 2, the arm 4 receives a combined movement to the right and in an anticlockwise direction with respect to and aboutu the stud 3 as a pivot; thus causing the stud 3 to have a relative movement outwardly with respect to the arm 4. As the raising of the lid 2 progresses, the stud 3 slides along the upper wall of the slot 6` and along the under side of the latch 11, the tail of which bridges the upper` portion ofthe enlarged recess 7, and passes outwardly until it reaches the yieldable restriction caused by the detent 15, and upon striking the detent 15 the vaction of the spring 17 is overcome, thereby causing the latch 11 to'rotate in a clockwise direction and allow the stud to pass under the 4detent 15 outwardly until it reaches the. stop recess 9, which stop positively` limits the further opening or upward movement of the lid 2. The lid 2 is now released, and upon such release the stud 3 guided into the recess 14 by the underside of the lip 10 and is prevented from retracing its outward path by mean-s of the detent 15; thereby resulting in the stud 3 being positively positioned within the recess 14 and positively held in this position by, means of the front face of the detent 15. It will therefore 'be seen that this provides a positive locking action which results in locking the holder between the lid 2 and the stud 3 which is attached to the body 1. When it is desired to lower or close the lid 2, the lid is given an upward or outward movement to further open the same, which brings the inclined inner face of the lip 10 into engagement with the stud, thereby forcing the stud upwardly along the incline 10 where it strikes the nose 16 and lifts f the same against the action of the spring 17 and passes into the pocket at 8; and upon lowering or releasing the lid 2 the stud passes rearwardly along. the upper edge of recess 7 and downwardly until it engages the inwardly extending tail of the latch 11 which yields downwardly allowing the stud to retrace its path along the slot 6 inwardly. It will therefore be seen that by means of the mechanism above described and its mode of operation a positive unlocking means is furnished. Due to the unique construction and disposition of the various parts, the entire locking and unlocking operation is 'semi-automatic and it is entirely positive in each of its respective movements throughout each cycle of operation; each cycle of operation comprising initially raising the lid to its maximum position as limited by the holder and then re- .leasing the same to thereby lock the lid in open position, then further opening the lid at slight distance, to positively release t-he locking mean-s, and then ,releasing or moving the lid to its closed position. All of these movements throughout the cycle are effected merely by engagement with the lid itself by means of one hand and after the lid has initially been raised to the limit allowed by the stop it may not again be closed without passing through the remainder of the cycle of operation as above described.

Where the holder is used in the position shown in the drawings, i. e. where the movenient of the holder is in a vertical plane, instead of utilizing the spring 17 to normally hold the latch in open position, the modification shown in Figs. 5 and 6 may be utilized. In these figures a similar construction is shown to that above described with the exception that in place of the spring 17 a suitable weight 17 is placed on the outer end of the latch 11 causing it to assume its normal position by Gravity.

In the embodiment herein illustrated the holder is supported in such a manner that gravity tends to rotate it in an anti-clockwise direction about the stud 3; but an understanding of its construction and operation will clearly show that it is entirely independent of the force of gravity for its operation, and in this respect it differs essentially from all of the devices of this general character which have heretofore been utilized. A consideration of this feature will make it obvious that the device is adapted to be used on closures which are adapted for vertical movement or horizontal movement. It is likewise obvious that the holder is not restricted to its use in connection with independent hinge means, but is adapted to be used as a holder for any type of structure where it is desired to successively move a part of such structure away from and toward the cooperating structure and .to hold the movable structure in locked position with the relatively fixed cooperating structure..

While I have described my invention according to the preferred embodiment of the same it will be obvious to those skilled in the art, after understanding my invention, that various alterations, modifications, and substitutions may be made without departing from the scope of the invention, and I aim in, the appended claims to cover all such modifications.
