Abstract
A security device for storing and retaining of products or product packing devices such as pallets, crates and the like having a clamping mechanism slidably mounted on and drivable with respect to a vertical column, the clamping mechanism including one or more pivotally mounted arms carrying one or more clamping pads adapted to clamp a stack of products or product packing devices between a pad and base member of the device.
Claims9
A security device for securing a stack of product or packing device articles comprising:
- a vertical column member having a lower end;
- sleeve means slidably mounted with respect to said vertical column member;
- an arm means connected to said sleeve means;
- a clamping pad connected to said arm means;
- means for pivoting said arm means with respect to said sleeve means;
- a base means;
- means for attaching said base means adjacent the lower end of said vertical column member beneath said clamping pad;
- means for moving said clamping pad up and down on said vertical column member and for locking said clamping means in position against a stack of said articles to retain said articles in a secure and locked position between said base means and said clamping means;
- and
- means for pivoting said clamping pad with respect to said arm means.

A security device for securing, at a location, first and second stacks of stackable articles comprising:
- frame structure means for at least partially surrounding said first and second stacks of said articles, part of said frame structure means being positioned for separating said first and second stacks;
- a vertical column attached to the part of said frame structure means positioned for separating said first and second stacks and extending above said frame structure means;
- a sleeve slidably mounted on said vertical column member;
- a swivel pivotally mounted on said sleeve;
- first and second tubular receivers rigidly fixed to said swivel on opposite sides thereof;
- first and second arms inserted into a respective one of said first and second tubular receivers and extending on opposite sides of said vertical column and over the location of said first and second stacks, respectively;
- first and second pads pivotally mounted to said first and second arms, respectively, each pad including a retaining frame;
- and
- means for driving said sleeve up and down on said vertical column and for locking said sleeve in position on said vertical column, thereby locking each said retaining frame in a retaining position for retaining a respective one of said first and second stacks.

- first and second pads pivotally mounted to said first and second arms, respectively, each pad including an "H"-shaped retaining frame;
- first and second sprocket means mounted to an upper and lower position of said vertical column, respectively;
- a chain mounted to revolve about said first and second sprocket means;
- means for attaching said sleeve to said chain;
- means for driving the second sprocket means for causing said sleeve to travel up and down on said vertical column, said drive means comprising:
- a crank rod;
- a removable crank handle;
- means for preventing slipping of said crank handle, and
- means for locking said removable crank handle in position.
