Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
182 words
A connecting unit for connecting together a plurality of plate-like members, said connecting device comprising a first one-piece member having a plurality of pairs of walls with the walls of each pair being in parallel relation and spaced apart a distance corresponding substantially to the thickness of platelike members to be connected together to form a recess and the pairs of walls being at a preselected angle to one another, a selectively usable second member formed separate and apart from said first member, each said recess opening through opposite ends of said first member and said second member being in the form of a closing plate closing said recesses at one end thereof, said closing plate having a pair of spaced walls extending between each adjacent pairs of walls of said first member and each pair of closing plate walls defining a notch for receiving a corner of a closing panel-shaped member, and securing means releaseably securing said second member to said first member with said second member engaging said member first walls at said recesses one end and closing the same.
Claim 2
Dependent Claim
182 words

Claim 4
Dependent Claim
30 words
The connecting unit of claim 2 wherein a like first member is in spaced aligned relation with the first mentioned first member, and a bar extends between said first members.
Claim 5
Dependent Claim
31 words
The connecting unit of clAim 3 wherein said bar is a spacer for connected adjacent panel-shaped members and has a rectangular cross section corresponding to the thickness of adjacent panel-shaped members.
Claim 6
Dependent Claim
20 words
The connecting unit of claim 4 wherein said bores in said hubs correspond to the cross section of said bar.
Claim 7
Dependent Claim
31 words
The connecting unit of claim 4 wherein said bores in said hubs are circular in cross section and at least end portions of said bar are of a like cross section.
Claim 8
Dependent Claim
28 words
The connecting unit of claim 1 wherein all of the adjacent pairs of walls of said closing plate are formed by two cover plates separated by radiating strips.
Claim 9
Dependent Claim
51 words
The connecting unit of claim 1 wherein all of the adjacent pairs of walls of said closing plate are formed by two cover plates separated by radiating strips, and the strips are of a width corresponding to the spacing between remote surfaces of said pairs of walls of said first member.
Claim 10
Dependent Claim
35 words
The connecting unit of claim 1 wherein said securing means are in the form of cooperating projecting pins and aligned recesses carried by said closing plate and said spaced parallel walls of said first member.
Claim 11
Dependent Claim
140 words
A connecting unit for connecting together a plurality of plate-like members, said connecting unit comprising separate first and second members, said second member including a pair of parallel walls, at least two spacer means extending between said parallel walls and permanently securing said parallel walls together, said parallel walls defining between said spacer means at least one pocket for a corner of a plate-like member, said first member including at least two pairs of parallel walls disposed at a fixed angle to one another and the walls of each pair being spaced apart to define a notch for receiving a corner of a plate-like member, and means releaseably securing said first member to said second member with said first member walls being in alignment with said spacer means, said first member walls being substantially normal to said second member walls.
Claim 12
Dependent Claim
140 words
A connecting unit for connecting together a plurality of plate-like members, said connecting unit comprising separate first and second members, said second member including a pair of parallel walls, at least two spacer means extending between said parallel walls and permanently securing said parallel walls together, said parallel walls defining between said spacer means at least one pocket for a corner of a plate-like member, said first member including at least two pairs of parallel walls disposed at a fixed angle to one another and the walls of each pair being spaced apart to define a notch for receiving a corner of a plate-like member, and means releaseably securing said first member to said second member with said first member walls being in alignment with said spacer means, said first member walls being substantially normal to said second member walls.
Claim 13
Dependent Claim
141 words
A connecting unit for connecting together a plurality of plate-like members, said connecting unit comprising separate first and second members, said second member including a pair of parallel walls, at least two spacer means extending between said parallel walls and permanently securing said parallel walls together, said parallel walls defining between said spacer means at least one pocket for a corner of a plate-like member, said first member including at least two pairs of parallel walls disposed at a fixed angle to one another and the walls of each pair being spaced apart to define a notch for receiving a corner of a plate-like member, and means releaseably securing said first member to said second member with said first member walls being in alignment with said spacer means, said first member walls being substantially coextensive with respective ones of said spacers.
Claim 14
Dependent Claim
141 words
A connecting unit for connecting together a plurality of plate-like members, said connecting unit comprising separate first and second members, said second member including a pair of parallel walls, at least two spacer means extending between said parallel walls and permanently securing said parallel walls together, said parallel walls defining between said spacer means at least one pocket for a corner of a plate-like member, said first member including at least two pairs of parallel walls disposed at a fixed angle to one another and the walls of each pair being spaced apart to define a notch for receiving a corner of a plate-like member, and means releaseably securing said first member to said second member with said first member walls being in alignment with said spacer means, said first member walls being substantially coextensive with respective ones of said spacers.
