Convertible barricade and method for its use
View Patent ↗A collapsible A-frame sign that can be converted into a panel that is capable of interlocking with other panels to form a physical barricade. When used alone, the device works as an A-frame sign or barrier by folding two frames hinged around a common end at the top of frames to form an A-shape allowing it to be erected in an upright position. Additionally, the device can be locked into a 180-degree angle, and joined with other identical devices to form a barricade at a height twice of the length of single frame. As a result, a group of locked devices can be used as a barricade as well as a warning signs.
1. A barricade device comprising:
two substantially planar member frames, each member frame comprising:
an upper end and an opposing lower end, with opposing first and second sides connecting the upper and lower ends,
the upper end of each member frame including at least one hinge knuckle configured to engage a complementary hinge knuckle on the other member frame,
the lower end of each member frame including a connecting pin on the first side thereof and a female connecting pin receptor on the second side thereof, both substantially parallel to the member frame, wherein each female connecting pin receptor is configured to receive a connecting pin of a second barricade device to create a barricade connecting joint;
both frames pivotably connected to each other about a first axis defined along the upper end of each member frame and extending through first openings in the hinge knuckles by a hinge/locking mechanism connected to at least one of the member frames adjacent the upper end thereof;
the hinge/locking mechanism comprising:
a locking pin passing through the first openings in the hinge knuckles of both member frames, and
a second pin, parallel to and connected with the locking pin, wherein the second pin is configured for insertion into second openings in the hinge knuckles, offset from the first openings;
wherein the member frames are pivotable between:
an A-frame configuration, wherein the member frames form an acute angle about the first axis and the second pin is not inserted into the second openings, and
a fence configuration, wherein the member frames form a 180 degree angle about the first axis, the second pin is inserted into the second openings thereby locking the member frames into the fence configuration, and the connector pins and female connecting pin receptors are aligned so as to pivotably engage with the female connecting pin receptors and connector pins of a second barricade device, respectively, about a second axis perpendicular to the first axis.
2. The barricade device as recited in claim 1 wherein the locking pin comprises a pin section, and locking rings.
3. The barricade device described claim 2 wherein the locking pin further comprises a locking pin handle.
4. The barricade device described in claim 1 wherein one or more member frames comprises a sign frame configured to connect to a sign.
5. The barricade device described in claim 1 wherein one or more member frames comprises a handle.
6. The barricade device described in claim 1 wherein one or more member frames comprises a hinge stabilizer.
7. A method for using two or more barricade devices to create a fence, the method comprising:
providing a first barricade device and a second barricade device, each comprising a barricade device according to claim 1 ;
placing the first barricade into the fence configuration and locking it into the fence configuration by inserting the second pin of the first barricade through the second openings of the hinge knuckles of the first barricade;
placing the second barricade into a fence configuration and locking it into the fence configuration by inserting the second pin of the second barricade through the second openings of the hinge knuckles of the second barricade; and
connecting at least one connecting pin of the first barricade to at least one female connecting pin receptor of the second barricade along the second axis to create a barricade connecting joint.
8. The method described in claim 7 wherein at least one connecting pin of the second barricade is connected to at least one female connecting pin receptor of the first barricade to create a second barricade connecting joint.
