Abstract

A joining device for connecting furniture parts includes two structural members each being a dowel housing and both having the same diameter.

One housing has a connecting member and the other housing has a locking member. When joined the connecting member projects into the housing with the locking member and is held by the latter.

Claims

1. A joining device for connecting two flat furniture parts, said joining device comprising:

a dowel-shaped first housing adapted to be rigidly fixed within a hole in a side wall of a first flat furniture part, said first housing having therein an outwardly facing opening;

a dowel-shaped second housing adapted to be rigidly fixed within a hole in a side wall of a second flat furniture part, said second housing having a planar edge surface adapted to be in coplanar alignment with the plane of an end surface of the second flat furniture part when said second housing is fixed within the hole in the side wall of the second flat furniture part, the diameter of said first housing being equal to the diameter of the said second housing and said second housing having a stop flange at one end thereof;

a connecting pin integral with and extending outwardly from said planar edge surface of said second housing, said connecting pin extending into said opening in said first housing, said connecting pin including a projection; and

locking means rotatably mounted in said first housing for, upon rotation thereof, acting upon said projection and moving said connecting pin axially inwardly of said opening and for thereby moving the end surface of the second flat furniture part into abutment with the side wall of the first flat furniture part.
