Abstract
A pressing device is disclosed including a housing, a lower engaged to that housing and adapted to receive products to be pressed and an upper platen engaged to the housing and manually translatable with respect to the lower platen. A handle mechanism is connected to the upper platen for translating the upper platen with respect to the lower platen. The handle mechanism includes a resilient over-center locking mechanism for translating the upper platen to a locked position proximate the lower platen, whereupon the upper platen is further translated towards the lower platen independent of manual force.
Claims10
A pressing device for manually compressing products comprising:
- a) a housing;
- b) a lower platen engaged to the housing and adapted to receive products to be pressed;
- c) an upper platen engaged to the housing and manually translatable with respect to the lower platen;
- d) a handle mechanism connected to the upper platen for translating the upper platen with respect to the lower platen, the handle mechanism including a resilient over-center locking mechanism for translating the upper platen to a locked position proximate the lower platen, whereupon the upper platen is further translated toward the lower platen, independent of manual force;
- e) the handle mechanism further comprising at least one resilient compression member connected to the over-center locking mechanism, the resilient compression member being operative to urge the upper platen towards the lower platen at a substantially constant compressive force;
- and
- f) an adjustment mechanism, connected to the resilient compression member, for adjusting the operating length of the resilient compression member.

- and
- e) the handle mechanism further comprising at least one resilient compression member connected to the over-center locking mechanism, the resilient compression member being operative to urge the upper platen towards the lower platen at a substantially constant compressive force and being deformable to allow the lower platen to translate to a slanted position relative to the upper platen as the upper platen is translated upwardly therefrom.
