Abstract
Abstract A building set for the setting up of a rectangular, upright plate forming the basis for adhered text comprises: (a) two uniform, rectangular plate sections (1,2) with tracks (3,4), dovetailed in cross-section, on the internal sides facing each other, (b) at least one split locking means (5) whose parts (6 and 7) can be inserted into the tracks (3,4) and, upon displacement transversely to the tracks (3,4), fix by wedge effect the two plate sections (1,2) around (c) a vertical end profile (9,10) at either end of the sign. One or both of the end profiles (10) may form a carrier means (13) for the sign, and said carrier means (13) is capable of carrying several signs. This obviates the problem of disfiguring screws, bolts or the like on the vertical side faces of the plate as the two parts (6 and 7) of the locking means (5) may be mutually displaced transversely to the tracks (3,4) by means of screws which are concealed in the space between the plate sections (1,2).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
A building set comprising: two plate members having facing inside surfaces, each of which surfaces has a dovetail portion; at least one end member disposed between said surfaces; and split locking means for securing said plate members together, said split locking means including two locking members, each of which includes two tongues, both of which tongues cooperate with a dovetail portion in a different said plate member, and a wedging means for urging said locking members transversely of said dovetail portions to force said tongues into said cooperating dovetail portions, wherein the said tongues and dovetail portions have cross-sectional configurations which cooperate to provide a force urging said inside surfaces of said plate members together against said end member therebetween when said locking members are urged transversely of said dovetail portions.
Claim 2
Dependent Claim
131 words
A building set comprising: two plate members having facing inside surfaces, each of which surfaces has a dovetail portion; at least one end member disposed between said surfaces; and split locking means for securing said plate members together, said split locking means including two locking members, each of which includes two tongues, both of which tongues cooperate with a dovetail portion in a different said plate member, and a wedging means for urging said locking members transversely of said dovetail portions to force said tongues into said cooperating dovetail portions, wherein the said tongues and dovetail portions have cross-sectional configurations which cooperate to provide a force urging said inside surfaces of said plate members together against said end member therebetween when said locking members are urged transversely of said dovetail portions.
Claim 3
Dependent Claim
48 words
A building set as in claim 1; wherein said plate members are substantially rectangular with substantially identical dimensions; each said dovetail portion includes a female dovetail groove extending along the long dimension of said rectangle; and said end member is disposed at the short sides of said rectangles.
Claim 4
Dependent Claim
40 words
A building set as in claim 2; wherein the dovetail surfaces of said dovetail grooves are flat, said tongues have flat wedging surfaces for cooperating with said flat dovetail surfaces and said wedging means urges and said locking members apart.
Claim 5
Dependent Claim
76 words
A building set as in claim 2; wherein said end member includes a rectangular flat portion having a long side having substantially the same dimension as said short side dimension of said plate members and a short side having a dimension substantially equal to the distance between the outside surfaces of said plate members and a T-shaped portion having a top flange captured in transverse end grooves in said facing inside surfaces of said plate members.
Claim 6
Dependent Claim
42 words
A building set as in claim 2; wherein the outside surfaces of said plate members are flat for accepting indicia to serve as sign and said end member comprises a carrier means for said plate members for attachment thereof to adjacent structure.
Claim 7
Dependent Claim
22 words
A building set as in claim 5; wherein said carrier means comprises a post for supporting said plate members above a floor.
Claim 8
Dependent Claim
25 words
A building set as in claim 6; further comprising two said posts, each of which is disposed at a different end of said plate members.
Claim 9
Dependent Claim
37 words
A building set as in claim 6; wherein said post includes at least one axially extending T-shaped portion having the leg thereof disposed radially and the top flange captured in transverse end grooves in said plate members.
Claim 10
Dependent Claim
31 words
A building set as in claim 8; wherein said post includes a plurality of said T-shaped portions equally spaced around the periphery of said post for supporting more than one sign.
Claim 11
Dependent Claim
63 words
A building set as in claim 2; further comprising at least four said plate members disposed in pairs with the long sides of said pairs in contact, wherein each said tongue of said locking members is disposed in a dovetail groove in a different said plate member and said wedging means urges said locking members together for holding said four plate members together.
