Abstract
Abstract A toy activity center is provided with a base plate and a plurality of activity units to be received in holes in the base plate. The latter holes are defined by a silhouette plate whose edges are adapted to releasably receive the activity units. The units are formed with mechanical coupling means and the rear side of the base plate is provided with corresponding coupling projections so that the rear of the base plate may be used as a building base to which the activity units may be coupled.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A toy activity center comprising: a base plate having a front side provided with means for receiving a plurality of removable activity units and a rear side, each of said activity units including means for activation and audio or visual means responsive to said activation means and primary and secondary coupling means with a predetermined mutual modular spacing, said coupling means being adapted to be connected with the corresponding coupling means of another activity unit; and, the predominant part of the base plate rear side is provided with at least one of said primary and secondary coupling means with said mutual modular spacing.
Claim 2
Dependent Claim
103 words
A toy activity center comprising: a base plate having a front side provided with means for receiving a plurality of removable activity units and a rear side, each of said activity units including means for activation and audio or visual means responsive to said activation means and primary and secondary coupling means with a predetermined mutual modular spacing, said coupling means being adapted to be connected with the corresponding coupling means of another activity unit; and, the predominant part of the base plate rear side is provided with at least one of said primary and secondary coupling means with said mutual modular spacing.
Claim 3
Dependent Claim
49 words
An activity center according to claim 1 characterized in that the activity units are rectangular blocks whose top sides are provided with a plurality of protruding coupling studs and whose bottom sides are provided with a plurality of complementary cavities to receive the coupling studs of an adjacent unit.
Claim 4
Dependent Claim
70 words
An activity centre according to claims 1, 2, or 5 characterized in that the rear side of the base plate is provided with a plurality of rows of coupling studs with said mutual modular spacing and adapted to be coupled together with a fixing device for fixing the activity centre to a wall, with parts of the wall being fixed between the rows of coupling studs and the fixing device.
Claim 5
Dependent Claim
86 words
An activity center according to claims 1, 2, or 3 characterized in that the rear side of the base plate is provided with a plurality of rows of coupling studs with said mutual modular spacing and adapted to be coupled together with a fixing device including a flange whose edges facing the rear side of the base plate has friction increasing means for fixing the activity center to a wall, with parts of the wall being fixed between rows of coupling studs and the fixing device.
Claim 6
Dependent Claim
22 words
An activity centre according to claim 1, characterized in that the base plate has releasable locking members to engage the activity units.
Claim 7
Dependent Claim
42 words
An activity centre according to claim 5, wherein the front side of the base plate is provided with depressions to receive activity units, characterized in that the locking members comprise locking means for cooperation with the coupling means of the activity units.
Claim 8
Dependent Claim
65 words
An activity centre according to claim 6, characterized in that the locking means comprise a downwardly extending edge along the upper side of the depressions, said edge being adapted to be received between two rows of coupling studs on an activity unit, and a snap lock placed in the vicinity of the underside of the depression for cooperation with the underside of the activity unit.
Claim 9
Dependent Claim
65 words
An activity center according to claim 4 characterized in that the locking means comprise a downwardly extending edge along the upper side of the depressions, said edge being adapted to be received between two rows of coupling studs on an activity unit, and a snap lock placed in the vicinity of the underside of the depression for cooperation with the underside of the activity unit.
