Abstract

A device for joining one canvas board having a freshly painted surface to another board in spaced, substantially parallel relation thereto and protecting the freshly painted surface. A clip member in the form of a channel member is adapted to be fitted over an edge of one of the boards and an elongated spacer member is mounted on the clip member, in particular being secured at one end to a flange of the channel member, and is disposed so as to extend in a direction away from and generally perpendicular to the plane of the one canvas board. A pin member is secured to and extends from the spacer member in a direction away from and generally perpendicular to the plane of the one board and is adapted to be driven into the other board. Several devices, for example four, are used to join two canvas boards.

Claims

1. A device for joining one canvas board having a freshly painted surface to another board in spaced, substantially parallel relation thereto and protecting the freshly painted surface, said device comprising:

a a clip member adapted to be fitted over an edge of one of said boards so as to grip said one board adjacent the edge thereof, said clip member having a base portion disposed generally parallel to the edge of said one board and at least one flange extending from said base portion and along the surface of said one board when said clip member is fitted on the edge of said one board;

b a spacer member on said flange of said clip member and disposed so as to extend in a direction away from and generally perpendicular to the plane of said one board when said clip member is fitted on the edge of said one board, said spacer member being elongated and having an outer end surface disposed in a plane substantially perpendicular to the plane of said base; and

c a pin member extending out from said end surface of said spacer member in a direction away from and generally perpendicular to the plane of said one board and adapted to be driven into said other board so that said boards are spaced apart a distance substantially equal to the length of said spacer member;

d whereby said canvas board having the freshly painted surface can be joined to said other board by a plurality of said devices at corresponding locations spaced around said boards.

2. A device according to claim 1, wherein said clip member comprises a channel member having a base and a pair of flange members extending from said base, the distance between said flange members measured adjacent said base being not less than the thickness of said canvas boards measured at the peripheral edge thereof.

3. A device for joining one canvas board having a freshly painteD surface to another board in spaced, substantially parallel relation thereto and protecting the freshly painted surface, said device comprising:

a a clip member adapted to be fitted over an edge of one of said boards, said clip member comprising a channel member having a base and a pair of flange members extending from said base, the distance between said flange members measured adjacent said base being not less than the thickness of said canvas board measured at the peripheral edge thereof;

b a spacer member mounted on said clip member and disposed so as to extend in a direction away from and generally perpendicular to the plane of said one board when said clip member is fitted on the edge of said one board, said spacer member being elongated and having planar, mutually parallel end surfaces at opposite ends thereof, one of said end surfaces being secured to one of said flange members and the other of said end surfaces being disposed in a plane perpendicular to the plane of said base; and

c a pin member secured to and extending from said spacer member in a direction away from and generally perpendicular to the plane of said one board and adapted to be driven into said other board;

d whereby said canvas board having the freshly painted surface can be joined to said other board by a plurality of said devices at corresponding locations spaced around said boards.

4. A device according to claim 3, wherein said pin member extends outwardly from said other end surface of said spacer member and at a right angle to said other end surface.

5. A device according to claim 2, wherein the corner of each flange at one end of said clip member is bent outwardly to facilitate fitting said clip member onto the edge of said board.

6. A device according to claim 2, wherein each of said flange members is disposed so as to define with said base member an angle less than ninety degrees.

7. A device for joining one canvas board having a freshly painted surface to another board in spaced, substantially parallel relation thereto and protecting the freshly painted surface, said device comprising:

a a clip member adapted to be fitted over an edge of one of said boards, said clip member comprising a channel member having a base and a pair of flange members extending from said base, the distance between said flange members measured adjacent said base being not less than the thickness of said canvas board measured at the peripheral edge thereof, each of said flange members being disposed so as to define with said base member an angle less than ninety degrees;

b a spacer member mounted on said clip member and disposed so as to extend in a direction away from and generally perpendicular to the plane of said one board when said clip member is fitted on the edge of said one board;

c one of said flange members being formed with a portion between the ends thereof disposed so as to define with said base member an angle of ninety degrees and said spacer member being secured to said flange portion; and

d a pin member secured to and extending from said spacer member in a direction away from and generally perpendicular to the plane of said one board and adapted to be driven into said other board;

e whereby said canvas board having the freshly painted surface can be joined to said other board by a plurality of said devices at corresponding locations spaced around said boards.

8. A device according to claim 7, wherein said spacer member is elongated and has planar, mutually parallel end surfaces at opposite ends thereof, one of said end surfaces being secured to said flange portion and the other of said end surfaces being disposed in a plane perpendicular to the plane of said base.

9. A device according to claim 8, wherein said pin member extends outwardly from said other end surface of said spacer member and at a right angle to said other end surface.

10. A device according to claim 6, wherein the corner of each flange at one end of said clip member iS bent outwardly to facilitate fitting said clip member onto the edge of said board.
