Abstract

Hollow frame members (1, 11), having openings (2, 12) to hold a picture along its longitudinal direction, and having connection faces (3, 13) cut to 45.degree. at its ends, receive each insertable leg part of an L-shaped corner connection fitting (5, 15). The frame members (1, 11) connect to each other in perpendicular relationship to form a square form. One stage or two stage engaging means consisting of stoppers (6, 16) and stopper holes (4, 14) at the corner part of the frame members enable expansion of the frame surface, allowing for assembly or disassembly, and easier replacement of pictures. Spring parts or guides (7, 17) are formed on the corner connection fittings (5, 15), to eliminate looseness of the frame members, and to make insertion and withdrawal smoother. The stoppers (6, 16) can be formed as one body with the corner connection fittings (5, 15) with a resin having elasticity to make the manufacturing of the corner connection fitting easier. The frame is formed with a groundpaper base (18) at the opening part (2, 12) to make setting or changing of the puzzle or photo easier.

Dependent claims

A frame to support a picture, comprising:

(a) frame members having a front edge, side edge and back edge, said edges forming a longitudinal opening to hold a longitudinal edge of the picture, said frame members having hollow end portions with connection faces at a 45.degree. angle, each of said frame members including a stopper hole within said back edge, said stopper hole being rectangular in shape and extending in a longitudinal direction of said frame member;
and
(b) an L-shaped corner connection fitting having two legs, each leg being insertable in a frame member so as to connect said frame members in perpendicular relationship, said corner connection fitting having a first and second edge with an intervening central portion therebetween, one of said edges having a flange to guide insertion and withdrawal with respect to said frame member, each leg including a rectangular, longitudinal stopper having a length slightly smaller than the length of said stopper hole, said stopper being engageable within said stopper hole, a first end of said stopper being interconnected to said corner connection fitting as a unitary body with said corner connection fitting.

A frame to support a picture, comprising:

(a) frame members having a front edge, side edge and back edge, said edges forming a longitudinal opening, said frame members having a groundpaper base interconnected to and parallel with said back edge to hold a longitudinal edge of the picture, said frame member having hollow end portions with connection faces at a 45.degree. angle, each of said frame members including a stopper hole within said back edge, said stopper hole being rectangular in shape and extending in a longitudinal direction of said frame member;
and
(b) an L-shaped corner connection fitting having two legs, each leg being insertable in a frame member so as to connect said frame members in a perpendicular relationship, said corner connection fitting having a first and second edge with an intervening central portion therebetween, each leg including a longitudinal stopper having a length slightly smaller than the length of said stopper hole, said stopper being engageable within said stopper hole, said stopper extending in a longitudinal direction with respect to said leg and frame member, a first end of said stopper being attached to said corner connection fitting as a unitary body, wherein an opposite second end of said stopper is movable to allow disengagement of said stopper from said stopper hole in said frame member.
