Fixing device for a notice board
View Patent ↗A fixing device ( 11 ) for use with a notice board ( 33 ) having at least two spaced fixing holes ( 33 ) formed in the board, and comprising two pieces ( 12,13 ) for placement one either side of the board ( 33 ) each with a respective front face ( 15 or 17 ) which sits against the board ( 33 ), one piece ( 12 ) having spaced apart studs ( 18 ) thereon which in use pass through the fixing holes ( 33 ) to engage in retention holes ( 28 ) in the other piece ( 13 ), one of said two pieces ( 13 ) having a rear face ( 14 ) with attachment means ( 16 ) for attaching the device ( 11 ) to a support ( 31 ) and a resiliently flexible projection ( 27 ) which is engagable with surfaces on the support ( 31 ).
1. A fixing device for use with a notice board having at least two spaced fixing holes formed therein, the fixing device comprising two pieces for placement one on each side of the board, each piece having a body with a front face which sits against one side of the board, one piece having at least two spaced apart studs thereon which in use pass through respective fixing holes and engage in retention holes in the other piece, one of said two bodies having a rear face with attachment means thereon for attaching the device to a support and a resiliently flexible projection which is engagable with surfaces on the support, the studs being held in the respective retention holes by clip means formed integrally with the body of said other piece.
2. A fixing device as claimed in claim 1 , wherein the attachment means comprise said resilient flexible projection mounted on a raised base on said rear face and at least one longitudinal passageway provided underneath the base to accommodate a tie.
3. A fixing device as claimed in claim 2 , wherein the projection comprises a first pair of oppositely extending inclined flexible wings extending longitudinally of the respective body.
4. A fixing device as claimed in claim 3 wherein the wings are inclined at between 10-30 degrees from the body away from a raised base formed on the rear surface of the body.
5. A fixing device as claimed in claim 1 , wherein the attachment means comprise at least one fastener hole provided by aligned holes in both bodies to accommodate passage of a screw, nail, pin, or tack for securing the board to a suitable post or surface.
6. A fixing device as claimed in claim 5 , said fastener hole passing through the resilient projection.
7. A fixing device as claimed in claim 1 , wherein each clip means comprises a resilient frustoconical detent formed in the respective hole and tapering away from the respective front face, the detent flexing to allow passage of a respective head of a stud and engaging undercuts formed on said head.
8. A fixing device as claimed in claim 1 , wherein the studs have pointed heads to facilitate driving the studs through a board for the formation of fixing holes in the board.
9. A fixing device as claimed in claim 8 , wherein said other piece has a raised ring surrounding the retention hole on the side away from the board, the ring in use being higher than the stud head retained in said retention hole.
10. A fixing device as claimed in claim 1 , wherein the front face of each piece may be provided with sealing rings surrounding the respective stud or retention hole, the sealing rings in use sealing against a board surface.
11. A fixing device as claimed in claim 1 , wherein the attachment means are formed on said other piece and are located centrally of the body between two retention holes.
12. A fixing device as claimed in claim 1 , wherein the two elongate pieces are curved longitudinally.
13. A fixing device as claimed in claim 1 , wherein the front face of at least one of said two pieces is provided with spikes thereon for engaging the surface of a board.
14. A notice board comprising a sheet or board having at least two fixing holes therein and at least one fixing device according to claim 1 .
