Application May 27, 1941, Serial No. 395,345

19 Claims.

This invention relates to automatic mechanism for raising and lowering the cover of a container as it is slid out and moves back within a kitchen cabinet or elsewhere, and has for an object to provide a simple inexpensive device of this class. Another object is to provide such a device which is adapted to be installed with a platform and its supporting guide or track. A further object is to provide such a device that is proof against being attached incorrectly. Yet another object is to provide a mechanism for actuating the cover which is constructed to insure a definite and predetermined timing of the cover. Still another object is to provide cover actuating mechanism in rear of the container so as not to interfere with the filling of the container or be in danger of catching on anything.

In my Patent #2,247,232 dated June 24, 1941, for Container and support therefor, is shown and described a platform containing a receptacle which moves out and into a wall opening in response to opening of a door.

According to this invention lever mechanism is sold and installed with the platform and container as a. part of the combination, whereby the timing and opening of the cover is correctly set for convenient operation, and elimination of labor in installation to a desirable minimum is an important factor.

Fig. 1 shows one embodiment of this invention.

Fig. 2 illustrates another and slightly different embodiment.

Fig. 3 shows a lever mechanism for moving the container and raising its cover.

Fig. 11 is a side view from the right of the device as shown in Fig. 2.

Referring to Fig. 1. The platform I0 is preferably mounted on rear rollers H and the front roller II as is described in the aforesaid patent.

A container I2 is located on the platform as described in prior patent, and is provided with a cover l3, pivotally secured to the container at l5, from which rearwardly extends a projection l4. Pivotally secured at |6-a to the projection I4 is the link l6 which extends downwardly as illustrated. Pivoted at l1 to the platform is lever l8 whose upper end is pivoted at 22 to the link IS, the lower end of which is pivoted at 20 to a stationary support 2|. This support is secured to the floor or other stationary support and extends around and in back of the platform in the laterally mid-portion thereof where it may serve as an abutment to limit inward movement of the platform. The lower end of the link I6 is pivotally secured at 23 to the lever 18. On moving the platform forwardly these links take the position shown in dotted lines in Fig. 1 in which the corresponding parts have been designated with the same identifying numerals. As will be seen from Fig. l, sliding the platform forward causes the pivotal connection 22, between the lever 18 and link H! to be lowered. At the same time the pivotal connection 23 at the lower end of the link I6 is lowered causing the link IE to pull down on the cover extension I 4 and open the cover I3 of the container l2, in response to forward movement of the platform Hi. It will be understood that the lever l8 and link H! are of such length that when the platform is in its forwardmost position this lever and link shall not be in alignment, in order that on inward movement of the platform the lever and link may be raised to their full line positions in Fig. 1 without difficulty. Any well known or convenient mechanism for moving the platform outwardly is adapted for use with the embodiment therein illustrated. Such may include a connection between the platform and the door as is disclosed in the prior patent referred to above.

In Fig. 2 a similar platform l0 contains a similar container l2 having a cover l3 pivoted at l5. Unlike the embodiment illustrated in Fig. 1, that shown in Fig. 2 depends on a link 24 being pushed upwardly to raise the cover l3 by means of a pivotal connection 25 to a cover extension and located between the cover pivot l5 and the body of the container l2. Secured to a support 29, which is preferably fixed with respect to the platform I0, is a lever 21 pivoted at 28 to said support 29 and having its adjacent end 26 pivotally connected to the link. 24. The opposite end of the lever 21 is pivoted at 3| to the link 30 whose lower end is pivotally secured at 32 to a stationary support which does not move with the platform.

Only the link 24 and lever 21 in Fig. 2 are located centrally of the platform, whereas in Fig. 1 the links and lever are located centrally of the platform. By using the abutment support 2| of the type shown in Fig. 1 it is not necessary to use a two part link connected thereto, one part being on each side of the platform, but instead the link connected to the stationary abutment is centrally of the platform. In Fig. 2 as the lever 21 and link are lowered at their pivotal connection 3|, the connection 26 between the link 24 and lever 21 is raised, causing the connection 25 to be raised and the cover to be opened as shown in dotted lines in Fig. 2.

In Fig. 3 is shown a similar platform and container which are actuated by a pedal 33 located adjacent the forward part of the platform when retracted, the pedal 33 being shown in Fig. 3 as being slightly in advance of the platform in the full line position. This pedal is pivotally connected at 34 to a stationary support which does not move with the platform and the pedal lever extended rearwardly beyond the connection 34 to a point adjacent the rear of the platform where it is shown as being provided with an upstanding portion 35 for connection at 36 to the arm 31 of a bell crank lever 38 pivoted at 39 to a stationary abutment 46, as is shown in both Figs. 3 and 4. The other end of the lever 38 is pivoted at 4| to the lever 42 whose lower end is pivotally secured at 43 to the container l2, A tension link 45 is pivotally secured between a connection 44 on the lever 42 and an upper con nection 46 on a rearward extension of the cover, so that as the platform is moved forward the tension link 45 is pulled down opening the cover. While the pedal is shown in Fig. 3 as actuating a link and lever mechanism of the type shown in Fig. 1, it will be apparent that the same pedal may actuate a link and lever mechanism for opening the cover in the manner shown in Fig. 2.

Figs. 5 and 6 show a door 41 extending across an opening and having secured on the inner face thereof a projection 48, (Fig. 6); a link is connected at one end to a pivot 49 on the extension 48 while the opposite end of the link 50 is pivotall secured at 52 to the underside of the platform ID. The door 41 is hinged on a vertical axis 5| so that on opening the door the link 56 pushes the platform forward while on reclosing the door the link 56 pulls the platform rearwardly. An advantage of this type connection between the door and the platform over that described in the aforementioned patent is that greater forward movement of the platform is obtainable for a given angular movement of the door. As shown in Fig. 5 the platform is provided with a stationary abutment and support of the type shown in Fig. 1 and the container cover is opened by means of a lever mechanism of the type illustrated in Fig. 2. It will be understood however that a Fig. 1 or 3 type mechanism may be used for opening the cover when the platform is moved outwardly by opening the door.

The platform and guide shown in Fig. 7 may be of the type therein illustrated or of any other convenient form such as that shown in said patent referred to. Located beneath the platform I0 is a wall 53 fixed with respect to the platform support and containing an inclined cam slot or guide 54, shown in Fig. 8 as extending forwardly and upwardly from its rear portion. A lever 56 is secured to the cover so that as the platform is moved forward the cover is raised by its actuating rod moving upward. This rod 56 extends from the cover down through an opening or hole 51 in the platform I0 (Fig. 7). Its lower end portion has a rearward extension 56 as shown in Fig. 8 as being preferably provided with a roller 55 for lessening friction as the rod moves in the slot 54. Inasmuch as the container and the platform are desirably moved to a position in front of the position of the platform when retracted, and since the wall 53 should not preferably extend in front of the forward end of the platform when retracted, it may be understood that the rearward extension 56 on the lower end of the rod 56 permits the cover to continue its opening movement when the platform is further forward than would be the case if such rearward extension were not present and the roller 55 were attached directly to the end of the rod 56.

In Fig. 9 is shown a wall 58 corresponding to the wall 53 in Figs. 7 and 8, except that the cam slot 59 in the wall 58 slopes forwardly and downwardly with the result that a rod 60 connected to the cover is pulled down on sliding the platform forward to open the cover according to the type of cover actuating connection shown in Fig. 1. The cover actuating lever 60 in Fig. 9 will preferably have a rearward extension 6i! on its lower end for the same purpose mentioned in connection with the cover actuating lever in Figs. 7 and 8. In both Figs. 8 and 9 the cover actuating lever passes through a hole in the platform since the cam slot is located beneath the platform and the sides of the hole through which the cover actuating rod passes serve as a guide for this cover actuating rod. The portion of the cover actuating rod which engages in the cam slot 59 is preferably provided with an anti-friction roller or other appropriate mechanism for reducing friction of the rod moving in the cam slot. In both Figs. 8 and 9 the guide slot is preferably wide enough so that on moving the platform in one direction the roller engages on the one side of the slot, whereas in moving the platform in the opposite direction the roller engages the other side of the slot.

In Fig. 10 the container I2 is mounted to slide outwardly without the aid of any platform, a suitable supporting post 6| carries a lazy-tong type lever mechanism 62 to the outer end portion of which the container I2 is pivotally secured as illustrated. On pulling the container outward it is supported by the lever mechanism 62 and on retracting the container the lever mechanism 62 tends to collapse in the usual well known manner. For opening the cover l3 in response to outward movement of the container, a cover actuating rod or link 63 is connected to the cover in the general manner shown by Fig. 1. The cover actuating rod 63 is relativel short being attached to a pivotal connection 64 so that as the container is moved outward the connection 64 tends to move downward opening the cover; the converse occurs on retracting the container.

An especial advantage of the constructions illustrated is the location of the link and lever mechanism in rear of the container where it is out oif the way and inconspicuous. The lever and link mechanism illustrated is usually sold with the container and platform as a unit for installation. It is relatively fool-proof and certain and reliable.

The platform of Figs. 1 to 7 and the lazy tongs of Fig. 10 are both a supporting means for the container. The link and lever mechanism [9 and Is in Fig. 1 for example may be regarded as a means for automatically moving the cover actuating link l6, which means is engaged by a stationary support 2|, The pivot l1 functions as a guide for the link I6. In Figs. '7 to inclusive, are also found means for automatically moving the cover actuating rod or link and a stationary support engaged thereby. The edges of the hole 51 in Fig. 7 function as a guide for the cover actuating link 56, whereas in Fig. 10 such guide for the link 63 is provided by the pivot pin (unnumbered) but shown on the side of the container. The container used in a kitchen for waste material customarily has an inner and removable container within it as is well-known.
