Abstract
Abstract A wheel element for a toy building set has a substantially flat body from whose one face projects a plurality of equispaced parallel pins arranged in a plurality of mutually orthogonal rows and spaced apart by a distance corresponding to the pin diameter. The body has a circular periphery formed with an edge channel that acts as a seat for a tire ring. This ring is able to slide in the channel for use of the body as a wheel or the body can be constituted of two mutually rotatable members, one formed with the seat and one adapted to be anchored to some structure. It is also possible to provide both members with axially projecting oppositely directed connecting pins to allow the wheel to be used as a bearing between two structures. To this end the member carrying the tire can be formed of a pair of disks, one of which is annular and is provided with connecting pins over all of one face.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
116 words
A structural element for toys and the like comprising a body having a major flat face provided with an array of uniform crosssection individual projections each extending perpendicular from said face and fixed to said body, said body comprising a pair of disks having beveled edges defining a circular peripheral channel, and means interconnecting said disks along mutually confronting flat faces thereof, and a substantially circular ring rotatable relative to said array and received in said channel, said projections being equispaced from one another by a distance enabling the space between neighboring projections to receive a projection on a structural element having a similar array, said ring projecting outwardly beyond said body all around its periphery.
Claim 2
Dependent Claim
116 words
A structural element for toys and the like comprising a body having a major flat face provided with an array of uniform crosssection individual projections each extending perpendicular from said face and fixed to said body, said body comprising a pair of disks having beveled edges defining a circular peripheral channel, and means interconnecting said disks along mutually confronting flat faces thereof, and a substantially circular ring rotatable relative to said array and received in said channel, said projections being equispaced from one another by a distance enabling the space between neighboring projections to receive a projection on a structural element having a similar array, said ring projecting outwardly beyond said body all around its periphery.
Claim 3
Dependent Claim
116 words
A structural element for toys and the like comprising a body having a major flat face provided with an array of uniform cross-section individual projections each extending perpendicular from said face and fixed to said body, said body comprising a pair of disks having beveled edges defining a circular peripheral channel, and means interconnecting said disks along mutually confronting flat faces thereof, and a substantially circular ring rotatable relative to said array and received in said channel, said projections being equispaced from one another by a distance enabling the space between neighboring projections to receive a projection on a structural element having a similar array, said ring projecting outwardly beyond said body all around its periphery.
Claim 4
Dependent Claim
116 words
A structural element for toys and the like comprising a body having a major flat face provided with an array of uniform cross-section individual projections each extending perpendicular from said face and fixed to said body, said body comprising a pair of disks having beveled edges defining a circular peripheral channel, and means interconnecting said disks along mutually confronting flat faces thereof, and a substantially circular ring rotatable relative to said array and received in said channel, said projections being equispaced from one another by a distance enabling the space between neighboring projections to receive a projection on a structural element having a similar array, said ring projecting outwardly beyond said body all around its periphery.
Claim 5
Dependent Claim
22 words
The structural element defined in claim 1 wherein said ring has a low coefficient of friction and is slidable in said channel.
Claim 6
Dependent Claim
36 words
The structural element defined in claim 1 wherein said body is constituted by a pair of mutually rotatable members, one of said members having said major face and the other of said members carrying said ring.
Claim 7
Dependent Claim
24 words
The structural element defined in claim 3 wherein said one member is formed with an axially extending projection rotatably received in said other member.
Claim 8
Dependent Claim
21 words
The structural element defined in claim 4 wherein said other member is formed with an axially extending sleeve receiving said projection.
Claim 9
Dependent Claim
36 words
The structural element defined in claim 5 wherein said projection is formed with an axial bore, said structural element further comprising a retaining element snugly engageable in said bore and axially engageable against said other member.
Claim 10
Dependent Claim
43 words
The structural element defined in claim 6 wherein said other member is also formed with a central axial bore registering with said first-mentioned bore, said retaining element engageable in both of said bores and having a head of larger diameter than said bores.
Claim 11
Dependent Claim
152 words
A structural element for toys and the like comprising a body having a major flat face provided with an array of uniform cross-section individual projections each extending perpendicularly from said face and fixed to said body, and a substantially circular ring rotatable relative to said array, said projections being equispaced from one another by a distance enabling the space between neighboring projections to receive a projection on a structural element having a similar array, said body having a substantially circular outer periphery formed with a seat receiving said ring with said ring projecting outwardly beyond said body all around said periphery, said body being formed at its edge with an outwardly open channel constituting said seat, said ring having a low coefficient of friction and being slidable in said channel, said body comprising a pair of circular similar disks each formed with a frustoconically bevelled edge, said disks being attached flatly together.
Claim 12
Dependent Claim
152 words
A structural element for toys and the like comprising a body having a major flat face provided with an array of uniform cross-section individual projections each extending perpendicularly from said face and fixed to said body, and a substantially circular ring rotatable relative to said array, said projections being equispaced from one another by a distance enabling the space between neighboring projections to receive a projection on a structural element having a similar array, said body having a substantially circular outer periphery formed with a seat receiving said ring with said ring projecting outwardly beyond said body all around said periphery, said body being formed at its edge with an outwardly open channel constituting said seat, said ring having a low coefficient of friction and being slidable in said channel, said body comprising a pair of circular similar disks each formed with a frustoconically bevelled edge, said disks being attached flatly together.
Claim 13
Dependent Claim
22 words
