Camlock

摘要

A cam lock includes a cylindrical lock body with a flange extending radially from the distal end to be glued to a surface surrounding a mounting hole. The lock body has a bore extending axially, with an interior shoulder extending radially inwardly at the distal end. The shoulder includes two key channels extending therethrough parallel to the axis and spaced apart 90°. A central spindle extending coaxially in the bore has a distal neck received within the interior shoulder. The distal end of the spindle is provided with a keyway channel extending therein parallel to the axis of the assembly. A pin channel extends annularly in the proximal spindle, and subtends an angle of approximately 90° and a locking pin extends through a hole in the lock body into the pin channel to retain the spindle and limit the spindle rotation. A lock cam is configured to snap-engage a proximal neck portion of the spindle in a fixed attachment. A key has a cylindrical tubular key body insertable concentrically between the lock body shoulder and the distal end of the spindle. A pair of outer key lugs extend radially outwardly from the tubular key body to pass through the key channels of the interior shoulder of the lock body. A third key lug extends radially inwardly from the inner surface of the tubular key body to engage the keyway channel of the spindle.

主权项

1. A cam lock for securing a moving closure with respect to a fixed frame, including:
a lock body having a bore extending axially therethrough, and an interior shoulder disposed at a distal end of said bore and extending radially inwardly to define a narrow distal opening; at least one key channel extending through said interior shoulder parallel to the axis; a central spindle extending axially in said bore in rotatable fashion, said spindle including a distal portion extending axially and distally and configured to be received within said narrow distal opening and define an annular gap therebetween; a key having a tubular key body dimensioned to be received in said annular gap, said key including at least one outer key lug extending radially outwardly therefrom and positioned to slidably extend through said at least one key channel.
