Description

Field of invention

[0001] The present invention relates to a cutting set for a hair clipper with a hair transport element for removing hair sections after cutting. State of the art

[0002] When cutting hair with clippers, hair clippings tend to accumulate on the blades of conventional clippers, depending on the cutting position. This accumulation obstructs the view of the cutting area and hinders the feed of uncut hair. The hairdresser must therefore tilt the clippers to the side or shake the hair off the blades after each accumulation. This is particularly inconvenient when a final trim is required.

[0003] To solve this problem, EP 3 117 972 A1 proposes a hair clipper with a cutting set consisting of at least one fixed or adjustable shearing blade and a shearing blade driven to oscillate transversely, substantially parallel to the leading edge of the shearing blade, and comprising a hair transport element having transport teeth arranged substantially along and spaced apart from the cutting edge of the shearing blade, wherein the shearing blade is positioned between the shearing blade and the hair transport element, and wherein the cutting edge of the shearing blade projects beyond the leading edge of the hair transport element. While this cutting set fundamentally solves the problem of hair clippings being transported away by the cutting blades, very fine hair clippings can still slip behind the hair transport element when the blade is oscillating.This problem is exacerbated if a length adjustment device is present, allowing the oscillating blade to be moved forward and backward to set the cutting length. A cutting blade set too far forward can create a gap behind the hair transport element, preventing the element from effectively removing hair clippings, especially smaller hair fragments. Description of the invention

[0004] The object of the invention is to provide a way to transport away hair sections that cannot be reached by a conventional hair transport element.

[0005] This problem is solved by a cutting set according to claim 1. Further features that elaborate the invention are contained in the dependent claims.

[0006] A cutting set according to the invention for a hair clipper comprises a first cutting blade, a second cutting blade movable to the first cutting blade, wherein the second cutting blade is designed to be movable both laterally and forwards and backwards relative to the first cutting element; and a hair transport element which is arranged on the opposite side of the second cutting blade with respect to the first cutting blade and moves with it, wherein the hair transport element has a first row of adjacent steps (or teeth) which extend parallel to the first or second cutting blade, so that during the lateral movement of the second cutting blade the hair is transported from the steps to the side of the cutting combs, wherein the hair transport element has a second row of adjacent steps which is arranged parallel to the first row.The second row of steps extends the hair transport element to the rear, so that even when the movable cutting blade is pushed far forward, the hair sections are transported to the sides of the cutting set.

[0007] In particular, the first row of steps faces forward, and the second row of steps is rotated about its parallel axis relative to the first row, preferably by at least 45°, 60°, 70°, or 90°. A rotated second row of steps allows the hair sections that reach behind the movable cutting blade to be better captured by the steps. The steps are preferably identical in shape, but can also have different shapes and / or different spacings.

[0008] Furthermore, the second row of steps is preferably directed upwards, in the opposite direction to the contact surface of the cutting set. This ensures that the hairs that have fallen behind the first row of steps are removed.

[0009] The first layer of hair follicles preferentially protrudes upwards beyond the second layer. This allows the majority of the hair follicle to be transported away from the first layer.

[0010] The first set of steps can have steps that are mainly directed towards the cutting combs, especially upwards. This ensures that the hair sections come directly into contact with the hair transport element after cutting.

[0011] The hair transport element is preferably mounted on a transmission element for the drive movement of a hair clipper. This allows the hair transport element to be designed in a space-saving manner.

[0012] The first row of steps is preferably flat on the side opposite the cutting edges of the cutting combs. This ensures that the second row of steps can be arranged directly next to the first row and that there are no obstructions above the second row of steps.

[0013] The steps of the first and / or second row of steps have a cross-section that increases, particularly in the lateral direction (outwards). This allows the hair sections to be ejected more effectively from the individual steps.

[0014] Preferably, the steps of the second row are formed in a groove, particularly in a groove of a transmission element. Furthermore, the steps preferably do not protrude beyond the edge of the groove. This ensures that the second row of steps on the cutting set can be slid under the housing of the hair clipper.

[0015] The steps of the second row are inclined on the side facing away from the first row. This allows the steps to be enlarged. Preferably, a partition or divider, particularly symmetrical, is provided in the center of the first and / or second row. The partition is preferably designed as a vertical plate. This clear partition or divider ensures that the hair sections are transported more effectively to the side closer to the cutting edge. The partition can extend beyond the other steps of the first row to provide even better separation.

[0016] Preferably, the hair transport element has fixing hooks with which it can be attached to the second cutting blade. Brief description of the characters

Description of preferred embodiments

[0018] In Figure 1Figure 100 shows a hair clipper 100 in an isometric view. The hair clipper 100 comprises a main body housing 102 in which a motor 104 is arranged. A cutting set 50 is provided at the upper end of the main body housing 102. The cutting set 50 comprises a stationary cutting blade 52 and a movable cutting blade 54, the movable cutting blade 54 being displaceable forwards and backwards via an adjusting lever 106. The motor 104 drives a transmission element, which is set into an oscillating motion by a mechanism and transmits this motion to the movable cutting blade 54.

[0019] In the preferred embodiment shown, the hair transport element 10 is formed on the transmission element 60 so that the lateral movement can be transferred directly to the hair transport element 10. However, it is also conceivable that the hair transport element 10 is attached directly to the movable cutting blade 54.

[0020] Figure 2 This shows an isometric exploded view of the hair clipper. The motor 104, the cutting set 50 with the cutting blades 52 and 54, and the hair transport element 10 are more clearly visible here.

[0021] Figure 3 shows a side view of the exploded view Figure 2The arrangement of the individual elements is clearly visible here. The stationary cutting blade 52 is located at the upper end, with the movable cutting blade 54 positioned below and directly adjacent to it. The hair transport element 10 and the transmission element 60, which are formed together in the illustrated embodiment, are then located on the movable cutting blade 54. The stationary cutting blade 52 is attached to the main body of the hair clipper via a cutting set carrier 56, thus holding the movable cutting blade 54, the transmission element 60, and the hair transport element 10 between itself and the upper end of the main body of the hair transport element 10.

[0022] The hair transport element 10 is formed between the cutting blades 52, 54 of the cutting set 50 and the main body, which is received by the main body housing 102. The in Figure 4The hair transport element 10 shown is formed on the transmission element 60 and has a first step or row of steps 20, which is formed from several steps or teeth 22 arranged next to each other.

[0023] The steps are oriented forwards towards the cutting blade when the hair transport element 10 is installed in the hair cutting device 10, so that the hair sections can directly strike the steps 22 and be transported away. Preferably, each step can include a step element 23 directed upwards and laterally with respect to step 22, so that hair sections above the hair transport element 10 can also be captured. On the rear side, the first row of steps slopes down, particularly vertically, so that in a retracted position of the movable cutting blade 54, it can be drawn as close as possible to the housing.

[0024] The steps 22 have an inclined surface, so that the cross-section of a single step 22 increases from the step base 26, where it abuts a previous step 22, to the step edge 28.

[0025] A partition 24 is provided in the center of the first row of steps 20. This partition may be higher, but is preferably flush with the other steps in a side view. The steps on both sides of the partition are preferably formed in opposite directions. The partition 24 is not a step, is sloping on both sides, and in particular does not have an increasing cross-section. The partition 24 is preferably at least 0.5 mm thick, more preferably 1 mm or 2 mm thick, and less thick than a step 22.

[0026] With respect to the cutting edge of the movable cutting knife 54, a second row of steps 30 is arranged behind the first row 20. The second row of steps 30 is preferably formed in a plate-shaped base 40 and, analogous to the first row of steps, can have a central partition 34 and several steps 32 which point in opposite directions relative to the partition 34, depending on the side.

[0027] In Figure 5 The hair transport element 10 is shown in a top view. Here it is clearly visible how the steps 22 and 32 increase in size. In particular, in the second row of steps, the step edges 38 are wider than the step base 36, by means that the groove wall 42 of the second row of steps 30 is inclined.

[0028] Figure 6Figure 1 shows a side view of the hair transport element 10. On the side of the hair transport element 10 opposite the rows of steps, fastening hooks 48 are provided, which allow the hair transport element 10 to be attached to the movable cutting blade 54. The first row of steps 20 is slightly inclined backwards, in particular by 5° to 20°. Furthermore, the preferred vertical configuration can be seen on the back side of the row of steps 20. The second row of steps 30 preferably adjoins the first row of steps directly.

[0029] The Figures 7 and 8 Figure 100 shows the hair clipper in a side view with a movable cutting blade 54 extended and retracted. Figure 7 is the

[0030] Adjustment lever 106 is rotated backwards. This pulls the movable cutting blade 54, and consequently the hair transport element 10, backwards as well. In the preferred embodiment, where the second row of steps is formed in a groove in the plate-shaped base 40, so that the second row does not protrude beyond the base 40, the hair transport element 10 can be pulled backwards to the rear of the first row of steps. In this position, the second row of steps 30 is located mostly under the housing, and the gap behind the first row of steps 20 is very small. Therefore, the first row of steps 20 is essentially sufficient to transport the hair sections to the side of the cutting blades 52, 54.

[0031] in Figure 8The adjusting lever is turned forward, so that the movable cutting blade 54 is also in a far advanced position. It is clearly visible that in this position of the movable cutting blade 54, a gap O is created behind the first row of steps 20 between the back of the first row of steps 20 and the housing 102, in which hair clippings can accumulate. This is because the first row of steps can no longer transport the hair away. Reference sign
