Abstract
An interlocking construction arrangement for coupling together two members at a predetermined angular relationship. A male joining means is coupled to the first member and has an outwardly upstanding male portion extending from the first member at the predetermined angular relationship. A female joining means is coupled to the second member and the female joining means has walls defining a male portion receiving cavity. When it is desired to join the two members together the male portion is inserted into the cavity of the female joining means where it may be frictionally retained to provide a removable coupling between the members or bonded or otherwise secured together to provide a permanent coupling of the two members.
Claims16
An interlocking furniture arrangement for coupling together a plurality of intersecting members in an article of furniture in preselected angular relationships and comprising in combination:
- at least one first member having an inside surface and an outside surface;
- at least one second member coupled in an intersecting relationship to said at least one first member, and having an inside surface and an outside surface, and said inside surface of said at least one first member abutting said inside surface of said at least one second member at a first predetermined angular relationship;
- a male joining means coupled to said inside surface of said at least one first member at a preselected location thereon in regions adjacent said abutment to said inside surface of said at least one second member, and comprising:
- a base portion having a first surface and a second surface;
- first attachment means for attaching said first surface of said base portion to said inside surface of said at least one first member;
- and
- a male portion outwardly upstanding a first preselected height from said second surface of said base portion at said preselected angular relationship, and having a first preselected length along said base portion, and a first preselected thickness;
- a female joining means coupled to said inside surface of said at least one second member at a preselected location thereon in regions adjacent said abutment to said inside surface of said at least one first member, and in coupling relationship to said male joining means and comprising:
- a base portion having a first surface and a second surface;
- second attachment means for attaching said first surface of said base portion of said female joining means to said inside surface of second member;
- an outer portion spaced from said base portion and having walls defining an interior surface oppositely disposed to said second surface of said base portion, and said interior surface of said outer portion and said second surface of said base portion defining a male portion receiving cavity having an open end and a closed end and extending substantially parallel to said first surface of said at least one second member, and said male portion of said male joining member inserted in said cavity from said open end thereof, to provide said coupling relationship therebetween, and said cavity having a second preselected length along said base portion, a first preselected depth and a first preselected width;
- and
- retention means cooperatively interacting between said male joining means and said female joining means for retaining said male portion of said male joining means in said cavity of said female joining means in said coupling relationship.
