DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0036] As generally understood, the system of the present invention a system 10 formed with the control bar 12. Control bar 12 is preferably a single formed piece. Control bar 12 has a first end 14 having an upper planer surface 16, indicia 18 and a plurality of protrusions 20. Control bar 12 has a second end 22 with second end upper planer surface 24 second end indicia 20 and a plurality of Second and protrusions 28. Control bar 12 interacts with proximal cap 30 in order to provide desired movement about a central axis to lock and unlock a door where system 10 is installed. Distal cap 32 encloses the components of the system as demonstrated in FIG. 3. Connecting bolts 38 ultimately attach through proximal cap 30 securing distal cap 32 into position.

[0037] As demonstrated in FIGS. 6 and 7, is attached to door 60 on anterior surface 62, first end 14 of plate 12 serves as a lock or latch by contacting inner surface 66 of wall 64. Directional arrows demonstrates a central axis formed by one particular in the center of the circle of proximal cap 30 and secured onto plate 12.

[0038] As shown in FIG. 11, there are particular dimensions that are not merely design preferences but that have been utilized based on ratios of their measurements.

[0039] Dimension A is the overall length of plate 12. Although plate 12 may not be planer, and has a bend as shown in the figures, the dimension is measured from a top view.

[0040] Dimension D is the length as shown of first end 14, The ratio of D:A is preferably 1:1.8-2.2. In one preferred embodiment the ratio D:A is 1:2.

[0041] Dimension E is the width of plate 12.

[0042] The ratio of D:E is preferably 1:0.5-0.65. In one preferred embodiment the ratio D:E is 1:0.57 or 4:7.

[0043] Dimension B is the length of distal cap 32 and dimension C is the height of distal cap 32.

[0044] The ratio of C:B is 1:4.75-5.25. In one preferred embodiment the ratio C:B is 1:4.8

[0045] A preferred ratio of B:D:A is 3.2:3.5:7.5.

[0046] In the embodiment of FIGS. 19 and 21

[0047] System 500 is control bar 516 with first end 520 having upper surface 518. Control Bar 516 has protrusions 514 on each end as shown in the figures. Control Bar 516 rotates or pivots about central axis 522.

[0048] The ratios are as follows

[0049] Dimension N is the width of first end of control bar 516.

[0050] Dimension O is the length of plate 12

[0051] The ratio of N:O is preferably 1:0.5-0.65. In one preferred embodiment the ratio D:E is 1:0.57 or 4:7.

[0052] Dimension R is the width of second end of plate 12 in this configuration.

[0053] N:R has a ratio of 1:1.7-2.3. One preferred ratio is N:R is 1:2

[0054] Dimension P is the overall length of plate 12. Although plate 12 may not be planer, and has a bend as shown in the figures, the dimension is measured from a top view.

[0055] Ratio of R:P is 1:1.5-1.75. A preferred ratio is 1:1.58 or 4:6.33.

[0056] In all configurations, the system is installed on the lower portion of the door interior. The protrusions provide contact points whereby a user uses their foot, most often with a shoe or other footwear, and rotates the control plate to latch or lock the door into position. The locking and unlocking undertaken using the shoe so that one's hands do not handle the lock.

[0057] While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
