A device for trimming hair comprising a housing (3) and a head portion (9) with a cutting blade assembly (10), wherein the head portion (9) is rotatably mounted to the housing (3) and a comb attachment (20) is releasably attachable to the device to extend over the cutting blade assembly (10), the device further comprising a locking means (30,50) configured to fixedly engage the head portion (9) with the housing (3) when a comb attachment (20) is detached from the device such that the head portion (9) is prevented from rotating relative to the housing (3) and configured to disengage the head portion (9) from the housing (3) when a comb attachment (20) is attached to the device such that the head portion (9) is rotatable relative to the housing (3).
A device for trimming hair comprising a housing and a head portion with a cutting blade assembly, wherein the head portion is rotatably mounted to the housing and a comb attachment is releasably attachable to the device to extend over the cutting blade assembly, the device further comprising a locking means configured to lock the head portion to the housing when the comb attachment is detached from the device such that the head portion is prevented from rotating relative to the housing, and to unlock the head portion from the housing when the comb attachment is attached to the device such that the head portion is rotatable relative to the housing, wherein the comb attachment is releasably mounted to the head portion, and wherein the comb attachment comprises an urging protrusion which acts on the locking member to urge the locking member into its disengaged position.
A device for trimming hair comprising a housing and a head portion with a cutting blade assembly, wherein the head portion is rotatably mounted to the housing and an attachment is releasably attachable to the device to extend over the cutting blade assembly, the device further comprising a locking member configured to move between an engaged position, in which the head portion is prevented from rotating relative to the housing when the attachment is detached from the device, and a disengaged position, in which the head portion is rotatable relative to the housing when the attachment is attached to the device, wherein the attachment is releasably mounted to the head portion, and wherein the attachment comprises an urging protrusion which acts on the locking member to urge the locking member into its disengaged position.
