Claims
- 1. A towel dispenser comprising:
- (a) a housing defining at least one orifice;
- (b) a first electrically driven transport device for providing an unused towel portion through said at least one orifice;
- (c) a second electrically driven transport device for retracting a used towel portion through said at least one orifice;
- (d) control means for controlling said first electrically driven transport device and said second electrically driven transport device;
- (e) a movement sensor electrically connected to said control means, said movement sensor including;
- (i) a touch-contact element; and
- (ii) a piezoelectric element having a first contact region operatively associated with said touch-contact element and a second contact region operatively associated with said housing.
- 2. A towel dispenser as recited in claim 1, wherein said touch-contact element is configured as a batten projecting from a bar member in said housing.
- 3. A towel dispenser as recited in claim 2, wherein said piezoelectric element is configured as a strip member with said first contact region being fastened to said bar member of said touch-contact element and said second contact region being disposed between a clamping member operatively associated with said housing and a spring member being operatively associated with said housing.
- 4. A towel dispenser as recited in claim 3, wherein said clamping member is Configured as a threaded bolt mounted in adjustable relationship to said piezoelectric element.
- 5. A towel dispenser as recited in claim 4, wherein said spring member is configured as a helical spring mounted in coaxial relationship with said threaded bolt.
- 6. A towel dispenser comprising:
- (a) a housing defining at least one orifice;
- (b) a first electrically driven transport device for providing an unused towel portion through said at least one orifice;
- (c) a second electrically driven transport device for retracting a used towel portion through said at least one orifice;
- (d) control means for controlling said first electrically driven transport device and said second electrically driven transport device;
- (e) a movement sensor electrically connected to said control means, said movement sensor including means for adjusting the sensitivity of said movement sensor.
- 7. A towel dispenser as recited in claim 6, wherein said movement sensor further includes a touch-contact element and a piezoelectric element having a first contact region operatively associated with said touch-contact element and a second contact region operatively associated with said housing.
- 8. A towel dispenser as recited in claim 6, wherein said adjusting means is a threaded bolt operatively associated with said movement sensor.
