space requirements cable locks could be used though longer ones would provide too much freedom of movement to the skateboard and would not effectively constrain it within the slot 40 as mentioned above a single security rack unit includes two support members and locking structure for securing a skateboard therebetween in the embodiment illustrated in fig1 3b the support members 24 26 are differently sized that is at least one of the support members in this case the smaller support member 24 has a width smaller than the smallest wheelbase of any skateboard that the security rack 22 is designed to secure the larger support member 26 may have the same width or may be sized larger as shown the main advantage of providing a longer support member 26 is that it protects the opposed ends of the skateboard from damage that is without such protection the ends of the skateboard 22 may be kicked or step on furthermore the longer support member 26 provides some additional security in preventing theft of the skateboard a thief trying to pry the skateboard 22 from within the slot 40 cannot angle it out of the plane of the slot because of the abutting ends of the large support member 26 however even with two shorter support members the width of the slot 40 may be made sufficiently small to prevent any such angling indeed in a minimal sense two linear posts spaced apart and provided with locking structure over the top may function as the support members of the present invention and secure a skateboard therebetween fig4 illustrates an array 70 of skateboard security racks of the present invention comprising a plurality of alternating short and long support members more specifically a plurality of.
