Publication number: 20210078089Abstract: A post 22D may be disposed between holders 22H. Post 22D preferably does not extend from panel 22 as much as holders 22H. Post 22D may have a protrusion 22DD. Pushstick 70 may also have a detent or protrusion 70D extending therefrom. Preferably protrusion 70D moves past protrusion 22DD as pushstick 70 is moved along posts 22HP. Protrusions 70D and 22DD may contact, preventing pushstick 70 from moving along panel 22. Persons skilled in the art will recognize that protrusions 70D and/or 22DD may engage notches in panel 22 and/or pushstick 70, respectively. Persons skilled in the art will recognize that the interaction of protrusions 70D and/or 22DD can be used instead or in conjunction with the friction-based retaining arrangement, i.e., where friction is created between narrow area 71N and post 22HH, discussed above. Holders 22H and/or post 22D are preferably integrally molded with panel 22. Accordingly, pushstick 70 may be held unto the panel 22 without requiring any additional parts.Type: ApplicationFiled: September 11, 2020Publication date: March 18, 2021Inventors: Robert P.
