Collapsible carrier stand for heavy machine

A collapsible carrier for a heavy machine comprising:

• (a) an upper platform adapted to support the machine,
• (b) first leg means pivotally attached to the platform and extending downwardly and forwardly relative to the platform,
• (c) second leg means having upper extent located to support the platform and extending downwardly and rearwardly relative to the platform,
• (d) the first and second leg means pivotally interconnected below the level of said platform,
• (e) there being a slide surface integral with the platform and presented to transmit loading to said second leg means upper extent as said upper extent travels therealong between first and second positions corresponding to raised and lowered positions of the platform, and there being stops associated with the platform to limit said travel at said first and second positions,
• (f) releasable means to lock said second leg means upper extent to the platform,
• (g) and counterbalance means operatively connected with said first and second leg means to yieldably resist downward movement of the platform, thereby counterbalancing the weight of said machine,
• (h) said releasable lock means including at least one arm integral with the second leg means upper extent and projecting upwardly adjacent at least one of said stops in said first position of the second leg means upper extent, and at least one plunger carried by said arm to releasably attach to structure integral with the upper platform and block movement of the platform relative to said second leg means,
• (i) and including a second arm integrally carried by the second leg means upper extent, said one arm and said second arm projecting in guiding relation with the platform in all positions of said travel of the second leg means upper extent between said stops, whereby the second leg means upper extent and said platform have mutually guided relation during said travel,
• (j) said arms projecting upwardly at opposite sides of the platform to form with said second leg means upper extent a channel in which the platform is received and travels relative to the second leg means upper extent,
• (k) and an adjustable set screw carried by the second arm to engage a side of the platform.
