DISPLAY RACK OR TRAY Filed March 3, 1928 3 IVE \L IHVEHTORS JOHANNES TACOMA CAMILLE DE LEESCHOUWER- A'I'TO 'RHEY Patented Apr. 15, 1930 UNITED STATES JOHANNES TACOMA AND CAMILLE DE VLEESCHOUWER, OF AMSTERDAM, NETHERLANDS DISPLAY RACK OR TRAY Application filed March 3, 1928, Serial No. 258,990, and in Great Britain March 4, 1927.

This invention relates to an improvement in or modification of the arrangement accord ing to applicants pending patent application Serial No. 151,950 of December 1st, 1926. According to the said application the rack is mounted on a guide foot which is slidably arranged on a rail placed on the floor of a show case. The arrangement is thereby such that when the rack is drawn forward out of the 19 show case there is automatically drawn forward along a certain distance a rail on which the rollers of the rack roll forward when the rack is drawn out beyond the front face of the show case. The rack is thereby at its top end also guided in a suitable manner. The rack according to this construction is arranged rotatably in the guide foot and there is arranged a spring pressed latch in the guide foot which looks the rack in a certain position. so This latch is arranged rather near to the axis of rotation of the rack and in practice it appears that the rack which may be heavily loaded is not quite rigidly locked in position with regard to the guide foot. This is a detriment which is avoided by means of the novel construction which forms the features of the present invention.

According to the invention a disc member is rigidly connected to the rack. This disc to member may consist of a full disc or one or more parts of a disc of which preferably the rim portion is bent downward. This downward bent portion is provided with one or two holes whilst one or two resilient pins are arranged on the guide foot in such a manner that when the rack with disc member is rotated, said resilient pins can fall, in one or other position of the rack, in the hole or holes in the disc member and thereby lock said disc member with rack against rotation. The holes and pins are so formed that when the rack is turned with some force, the pins are pressed away and the rack can rotate fur ther.

In the accompanying drawing the invention is illustrated by way of example Figure 1 is a side view of the lower part of the rack with the arrangement according to the invention partially shown in vertical section, and i Figure 2 is a plan view of the disc member seen from above. a

The main rack bar 1 is provided with a cylindrical pin 2 which extends in a boring in a member of the guide foot. According to the construction described in the main patent a latch 3 arranged resiliently in the guide foot locks the rack in a certain position. According to the present invention the quadrangular rack bar 1 is provided with a disc member 4 which is rigidly connected to said rack bar 1. The rim of said disc member is bent downward and is provided with one or two borings 5, the edges of which are rounded. In the path of the downward bent rim of the disc member two resilient pins are arranged opposite to each other on the guide foot; said pins 6 are arranged slidably in casing 7 in which springs 8 tend to keep the pins in their outward position. The extending ends ofthe pins are rounded. The arrangement is such that when an opening 5 in the disc comes in alignment with the resilient pins, said pins will enter the opening thereby locking the rack bar in its position. WVhen the disc member 4 is constructed as a full disc the position of the two holes 5 in said disc determines the positions in which the rack bar can be locked. hen the disc member is not a full disc, the edges of the disc portion or portions are preferably sharpened as shown in Figure 2 at 9. It is obvious that the sharpened edges 9 will, when the rack is rotated, press the resilient pins 6 apart without a shock and will fall in one of the holes 5 when said hole comes into alignment with the pin. The arrangement is such that in the position of the rack in which the latch 3 locks the rack, the pins 6 also engage an opening 5 in the disc member, so that in this position, when the rack is moved in or out of the show case, the rack is held quite steady.

What we claim is 1. In a device of the class described, a rotatable rack bar, a support for the rack bar, a member having a curved wall fixed to said rack bar, a hole in said wall, and abutting oppositely disposed resiliently mounted pins, said wall being adapted to pass between the ins, said pins being mounted on the rack ar support.

2. In a device of the class described, arotatable rack bar, a support for the rack bar, a member having an arcuate shaped Wall fixed to the rack bar, a hole in said Wall, and oppositely disposed resiliently mounted pins, said wall having tapered ends and being adapted to pass between the pins, the pins being 10 mounted on the rack her support.

3. In a device of the class described, a totatable rack bar, a support for the rack bar, a member having an arcuate shaped wall fixed to said rack bar, a hole in said wall, and oppo- 15 sitely disposed spring pressed pins, the ends of said wall being tapered and the ed es of said hole being rounded, said wall ing adapted to pass between the pins, the pins being mounted on the rack bar support. 2 In testimony whereof, we affix our signatures.
