What is claimed is:
1. Scissors, especially for use by barbers and hairdressers, with two arms (3, 4) able to rotate around a hinge (2) with a cutting edge (5) on the blade (6) of each arm (3, 4) as well as a gripping element, especially a gripping ring (7) on each arm (3, 4), wherein the hinge (2) is formed by a pin (8) protruding through a slot (9) in the arm (3, 4) to join the arms (3, 4) together by means of the hinge, wherein the arms (3, 4) lie one on top of the other in the area of the hinge (2), each with a moving face (10), and wherein there is a drain (11) on at least one of the arms (3, 4) opening into the slot (9), the drain (11) borders on the moving face (10) and the drain (11) is surrounded by a wall (12).
2. The scissors according to Claim 1, wherein the drain (11) is filled with lubricant.
3. Scissors according to Claim 1 or Claim 2 wherein the drain (11) has been milled. |
SCISSORS WITH A DRAIN, PARTICULARLY FOR COLLECTING LUBRICANT
Scissors with a drain, particularly for collecting lubricant
The invention is related to scissors, especially scissors used by barbers and hairdressers with two arms that rotate around a hinge, one cutting edge on a blade of an arm, as well as a gripping element, especially one gripping ring per arm. The hinge consists of a pin protruding through a slot in the arm to connect the arms with each other by means of the hinge. The arms lie one on top of the other with one moving face each in the area of the hinge.
Scissors of this type have been known for a very long time. They have the disadvantage that they must be provided with lubricant for the hinge from time to time to be able to use them with absolute ease of motion over a long period of time. This oiling must be provided by a salon employee or a technician.
The object was to design scissors in such a way that they can be provided with lubricant for an extremely long time period.
The object is achieved by providing a drain on at least one arm designed so that the drain empties into the slot, that the drain borders on the moving face, and that the drain is surrounded by a wall. This makes it possible to put lubricant into the drain, which this ensures that the hinge is always provided with lubricant to reduce friction over the course of time. The drain can be milled into the arm in question, which is relatively cost-effective.
The invention is described below with the aid of diagrams illustrating an embodiment. The following is shown:
Fig. 1 A pair of scissors, opened
Fig. 2 An arm of the scissors of Fig. 1, wherein a drain surrounds a slot drilled in the arm
Fig. 3 The arm of Fig. 2 in a cross section along A-A.
A pair of scissors 1 for use by barbers and hairdressers has two arms 3, 4 able to rotate on a hinge 2. Each blade 6 of an arm 3, 4 has a cutting edge 5 as well as a gripping element designed in the form of a gripping ring 7. The hinge 2 is formed by a pin 8 protruding through a slot 9 in the arm 3, 4 joining the arms 3, 4 together by means of the hinge. The arms 3, 4 lie one on top of the other, each with a moving face 10 in the area of the hinge 2. One arm 3 has a drain 11 that opens into the slot 9. The drain 11 borders on the moving face 10. The drain 11 is completely enclosed by a wall 12.
Lubricant, e.g. some type of grease, can be placed in the drain 11 to continuously grease the area of the hinge 2. In this process, the grease penetrates into the area between the pin 8 and the drain 4, which rotates around the pin 8.
