Adjustable desk with bookcase

Abstract

A desk and bookcase combination includes a desk with a horizontal planar desktop member supported by spaced apart, tubular, telescoping support legs which may be selectively adjusted to adjust the height of the desk by insertion of locking pins with locking hook parts into respective sets of pin receiving openings in the leg members. The bookcase includes opposed end support members having lateral channel shaped supports for slidably receiving opposite desktop side edges and one or more vertically spaced pairs of brace members for receiving cooperating shelf members having downwardly facing channel-shaped support members which may be hooked over respective pairs of brace members, for selectively positioning the shelf members with respect to the desktop.

1 . A desk comprising: 
 a generally horizontally extending desktop member forming a planar work surface;    plural upstanding support legs spaced apart and secured to said desktop member, each of said legs comprising an upper leg member and a lower leg member, said lower leg member being telescopically received within said upper leg member;    a locking member engaged with said upper and lower leg members of each of said legs for locking said lower leg member in a selected telescoped position with respect to said upper leg member for adjusting the height of said work surface with respect to a support surface for said desk; and    a bookcase removably mounted on said desktop member.    
   
   
       2 . The desk set forth in  claim 1  wherein: 
 said upper and lower leg members comprise generally cylindrical tubular members and said lock member includes a lockpin insertable in pin receiving openings formed in each of said upper and lower leg members, respectively.    
   
   
       3 . The desk set forth in  claim 2  wherein: 
 said lockpin includes a lockpin part and a hook part for securing said lockpin part in a locked position with respect to said leg members, said hook part including a generally arcuate portion engageable with at least one of said upper and lower leg members in a selected locking position of said lockpin for securing said lockpin in said locked position.    
   
   
       4 . The desk set forth in  claim 3  wherein: 
 said lockpin includes a stem portion integrally joined to said lockpin part and said hook part of said lockpin.    
   
   
       5 . The desk set forth in  claim 1  wherein: 
 said leg members are interconnected by plural, spaced apart, generally horizontally extending brace members forming opposed pairs of said leg members, respectively.    
   
   
       6 . The desk set forth in  claim 5  wherein: 
 opposed ones of said leg members are interconnected by plural elongated brace members, respectively.    
   
   
       7 . The desk set forth in  claim 5  including: 
 a shelf adapted for support on said desk below said desktop member, said shelf including a generally planar shelf member and opposed end support members, said end support members including channel-shaped parts adapted to be hooked over selected ones of said brace members of said opposed pairs of said leg members, respectively.    
   
   
       8 . The desk set forth in  claim 1  wherein: 
 said bookcase includes spaced apart opposed end support members comprising, respectively, spaced apart upstanding column members and plural spaced apart brace members interconnecting said column members, respectively, and at least one shelf member supported by and between said end support members.    
   
   
       9 . The desk set forth in  claim 8  wherein: 
 said shelf member includes a generally planar shelf member part and opposed downwardly facing channel-shaped support members connected to said shelf member part and engageable with said brace members of said end support members, respectively, for positioning said shelf member in a selected working position on said bookcase.    
   
   
       10 . The desk set forth in  claim 8  wherein: 
 said bookcase includes opposed end support members including opposed channel shaped members, respectively, spaced apart and engageable with said desktop member by receiving opposite lateral side edges thereof, respectively, in said channel shaped members for supporting said bookcase on said desk.    
   
   
       11 . The desk set forth in  claim 1  wherein: 
 said desktop member comprises a unitary plastic laminate member.    
   
   
       12 . The desk set forth in  claim 11  including: 
 an elongated desktop member brace member secured to an underside of said desktop member.    
   
   
       13 . The desk set forth in  claim 1  wherein: 
 said desktop member includes a perimeter metal frame and a planar insert member secured to and enclosed by said perimeter frame at side edges thereof.
