Cessna 140 pilot reported a near miss with a glider that performed an abbreviated non-standard pattern upon release from tow at a non-towered airport. Pilot took evasive maneuver to avoid a collision with the glider then continued.

Narrative

AS I taxied to Runway XX the tow-plane and glider on XY announced hook-up (I could not see them from hold short on XX position). I held short of XX and announced intention to wait until they take off. 20-30 seconds later the tow plane announced they are on upwind turning crosswind. I announced taking off on XX and started takeoff roll and had tow-plane and glider in sight (right traffic on XY). As I lifted off into ground effect the glider announced abbreviated pattern and turned downwind while tow plane departed pattern area. I was already flying and fast; the glider was approximately 400ft AGL. I announced that I will not climb until passing the glider and continued at 10AGL; while monitoring our flight paths. We passed each other approximately 400ft vertically apart and I started climbing after that.This was a sub-optimal situation; I noted to tow+glider that I AM holding short for them and they did not announce abbreviated pattern until well after I started my takeoff (which I also announced). When I started my takeoff roll the glider was already too high for 180; but I SHOULD HAVE waited for it to cross XX before taking off (this would have required me to line up and wait on XX to see it). Even better; I should have waited 3min for them to reach their pattern altitude before taking XX; to ensure we have ~1000+ ft separation OR hearing of last sec glider intentions call.Moving forward I will not assume typical tow operations from gliders but assume the shortest most conflicting action a glider could take - either 180 or abbreviated pattern.The glider nor tow plane make any comments related to this situation as it played out. I do consider it to have resulted in unnecessary increase in risk event if in this SPECIFIC instance we were relatively far apart vertically.
