(42) The first leg 107 of the second clip 105 surrounds the first longitudinal side 15. The first leg 107 of the second clip 105 can surround a second cut-out 111 arranged on the first longitudinal side 15.
(43) In the embodiment with two clips 55, 105, the housing 9, as shown in
(44) The second leg 109 of the second clip 105 is received in the second through hole 113. As previously described, the second through hole 113 is arranged near the second longitudinal side 17. The first cut-out 85 is arranged at the common edge 115 of the first longitudinal side 15 and the first lateral side 19 whereas the second cut-out 111 is arranged at the common edge of the first longitudinal side 17 and the second lateral side 21.
(45) As for the first clip 55, the second leg 109 of the second clip 105, which is received in the second through hole 113, is bent around at least a portion of the bottom side 13, as shown on
(46) The bottom side 13 of the housing 9 can include a fulcrum portion 121 (or protruding portion) arranged to receive a portion of the second leg 109 of the second clip 105 which is bent over the fulcrum portion 121.
(47) The second end of the second clip 105, corresponding to the free end of the second leg can be tapered (preferably V-shaped).
(48) The shaving blade cartridge 1 includes a mid-plane Pm orthogonal to the longitudinal axis X-X, as shown on
(49) In a first embodiment, shown on
(50) The second through hole 113 is also arranged in or adjacent to the guard bar 99. The first leg 107 of the second clip 105 surrounds the rear cap 101.
(51) As shown in
(52) In a second embodiment, shown on
(53) In others embodiments (not shown), the first through hole 93 can be arranged in or adjacent to the guard bar 99, whereas the second through hole 113 is arranged in or adjacent to the rear cap 101. Thus, the second leg 61 of the first clip 55 is received in the first through hole 93 arranged in or adjacent to the guard bar 99, whereas the first leg 59 of the first clip 55 surrounds the first longitudinal side 15 provided at the rear cap 101 side. The second leg 109 of the second clip 105 is received in the second through hole 113 arranged in or adjacent to the rear cap 101, whereas the first leg 107 of the second clip 105 surrounds the first longitudinal side 15 provided at the guard bar 101 side.
(54) The clips 55, 105 can be assembled to the housing 9 by a system for the manufacture of clip-housing assemblies with, for example, the followings steps: providing the clip 55, 105, made of a formable material, assembling the clip 55, 105 to the housing by placing the first leg 59, 107 on the first longitudinal side 15 of the housing 9 and the second leg 61, 109 of the second longitudinal side 17 of the housing 9, deforming the first and second legs 59, 107, 61, 109 to cooperate with the bottom side 13 of the housing 9 to hold the cutting blades 35 within the housing 9 (and more precisely within the blade receiving section 33).
(55) The first and second legs 59, 107, 61, 109 can be deformed with a bending tool comprising assembly clamps (not shown) that bend the clip legs in position.
(56) The bottom of the housing 9 can also include a protrusion 125. The protrusion 125 extends along the longitudinal axis X-X and is provided preferably in the middle of the bottom side 13 of the housing 9. The protrusion protrudes from the bottom of the housing 9 along the lateral axis Z-Z. In a mounted position of the clip 55, the first end 37 of the clip 55 is on one side of the protrusion 125, whereas the second end 71 of the clip is on the other side of the protrusion 125. The protrusion 125 can advantageously protect the clip 55 from the assembly clamps. Indeed, in other cartridges, after the legs of the clips are bent into their mounted position by the assembly clamps, it may happen that the assembly clamps accidentally grab the ends of the clip when being moved away or removed from the blade cartridge provided with the clip, which can unbend the clip and result in scrapping the entire head. The protrusion 125 in the present invention does not allow the assembly clamps to accidently grab the clip end on their remove movement, and thus the protrusion 125 secures the position of the clip during mounting steps. The lower horizontal plane of the protrusion is in a substantially similar horizontal plane of the lower section of each leg of the clip disposed on the underside of the housing.
