| 20110197455 | METHOD FOR DETERMINING THE DIRTINESS OF AN ELECTRICALLY DRIVEN CUTTING TOOLS , AND HAIR CUTTING DEVICE - The invention pertains to a method for determining the dirtiness of a cutting tool and to a hair cutting device with an apparatus for determining the dirtiness of the cutting tool thereof. The method is intended for cutting tools that carry out a back and forth motion and are driven by an oscillating electric motor or linear motor. In order to determine the dirtiness in accordance with said method, a parameter is evaluated that is correlated with the respective state of motion of the cutting tool and used for controlling the oscillating electric motor or linear motor. Parameter changes are continuously measured and cause a dirtiness counter to count up if the parameter value exceeds at least one threshold value. The fact that the count of the dirtiness counter has reached or exceeds a reference value is then conventionally indicated. | 08-18-2011 |
| 20110232105 | Hair Cutting Machine - In order to provide the option of dividing up the hair with one-handed use of the hair cutting machine for a hair cutting machine having a gripping piece, two clipper blades, as well as a drive to generate a relative movement of the clipper blades, it is proposed that a dividing tip be provided on the hair cutting machine and that said dividing tip be connected to the hair cutting machine via a connection. | 09-29-2011 |
| 20120317821 | POWER TOOL - A power tool is provided with a first unit, a second unit rotatable with respect to the first unit, a lock operation member and a lock cooperative switch. The lock operation member is configured to be operated by the user between a lock position and an unlock position, and configured to prevent rotation of the first and second units at the lock position and allow the rotation between the first and second units at the unlock position. The lock cooperative switch is disposed on the supply circuit of energy to the prime mover, and configured to enable the supply circuit when the lock operation member is at the lock position and cutoff the supply circuit when the lock operation member is at the unlock position. | 12-20-2012 |
| 20130036615 | SHEATH FOR ELECTRIC CABLE AND TRIMMER - There is disclosed a sheath for an electric cable for an electrically-powered trimmer and to an electrically-powered trimmer comprising a sheath. The trimmer has a body and first and second cutting blades each having a plurality of teeth. The trimmer also has a sheath disposed about at least a part of the cable. At least one portion of the sheath can be received in the cutting space between teeth and extends beyond the cable by a distance that exceeds the depth d of the cutting space. At least one portion of the sheath is wider than the opening width w of the cutting space. Thus, the dimensions of the sheath prevent the cable from entering the cutting space for any orientation of the sheath. | 02-14-2013 |
| 20130067752 | MULTI-PART HAIR CLIPPER HOUSING LID - A multi-part hair clipper housing lid is provided that is configured for engagement upon a main hair clipper housing.
