The elongated coupling section and the flexible member have cooperating cam surfaces for moving the detent outwardly upon relative movement which increases the distance of the coupling retaining member from the front end of the attachment. Stop means limits the relative movement. The detent engages a detent member of the hand appliance when the attachment is coupled thereto. A slidable control member of the appliance prevents disengagement in the forward position thereof.，下面是Removable attachment for a hand appliance for body care including coupling retaining means专利的具体信息内容。
1. Coupling retaining means for releasably retaining the coupling of a removable attachment to a hand appliance for body care having an outpuT member, an outwardly extending detent member transversely spaced from the output member, and a control member slidably parallel to said output member and adapted to overlap said detent member in spaced relationship thereto, said removable attachment including a body portion having a working head toward the front end thereof and an elongated coupling section at the rear end thereof adapted for coupling with said output member of the hand appliance, said coupling retaining means comprising a. a coupling retaining member slidably mounted on said elongated coupling section of the attachment for movement therealong, b. said coupling retaining member including a spring arm extending longitudinally of said elongated coupling section with the rear end free for flexible movement outwardly from the elongated section, c. a detent on the inner side of said free end of the spring arm for engaging said outwardly extending detent member of the hand appliance, d. cooperating cam surfaces on said elongated coupling section and said spring arm, respectively, for moving said free end outwardly from the detent position thereof upon relative movement which increases the distance of the coupling retaining member from said working head, e. and stop means on said attachment for limiting said relative movement, f. the inner surface of said control member of the hand appliance and the outer surface of said spring arm of the attachment being designed and adapted to prevent disengagement of the detent from said detent member in a predetermined forward position of the control member.
2. Coupling retaining means in accordance with claim 1 in which said inner surface of the control member has an inward projection axially spaced from the front end thereof and adapted to overlap said free end of the spring arm in said forward position of the control member and prevent said disengagement of the detent.
3. Coupling retaining means in accordance with claim 1 in which said detent member of the hand appliance is an annular groove with an outwardly-extending lip and said detent on the free end of the spring arm of the attachment is an inwardly extending hook adapted to overlap said lip when in detent engagement therewith, said control member being adapted to overlap said free end of the spring arm in said forward position thereof, and the overlapping portion of the inner surface thereof being of rotational symmetry and closely adjacent the outer surface of said free end of the spring arm to prevent disengagement of said hook from said lip.
4. A removable attachment for a hand appliance for body care which comprises a. a body portion having a working head toward the front end and an elongated coupling section at the rear end thereof, b. a coupling retaining member slidably mounted on said elongated coupling section for movement therealong, c. said coupling retaining member including a spring arm extending longitudinally of said elongated coupling section with the rear end free for flexible movement outwardly from the elongated coupling section, d. a detent on the inner side of said free end of the spring arm, e. cooperating cam surfaces on said elongated coupling section and said spring arm, respectively, for moving said free end outwardly from the detent position thereof upon relative movement which increases the distance of the coupling retaining member from said working head, g. and stop means for limiting said relative movement including a recess on the inner side of said spring arm and a projection on said elongated coupling section extending into said recess and adapted to abut against at least one end of said recess to provide a corresponding stop.
5. A removable attachment for a hand appliance for body care which comprises a. a body portion having a working head toward the front end and an elongated coupling section at the rear end thereof, b. a coupling retaining member slidably mounted on said elongated coupling seCtion for movement therealong, c. said coupling retaining member including a spring arm extending longitudinally of said elongated coupling section with the rear end free for flexible movement outwardly from the elongated coupling section, d. said coupling retaining member encircling said elongated coupling section and having a longitudinally extending slot between the walls of which said spring arm is located, e. a detent on the inner side of said free end of the spring arm, f. cooperating cam surfaces on said elongated coupling section and said spring arm, respectively, for moving said free end outwardly from the detent position thereof upon relative movement which increases the distance of the coupling retaining member from said working head, g. said cam surfaces inclining outwardly and rearwardly from said elongated coupling section, h. and stop means for limiting said relative movement.
6. An attachment in accordance with claim 4 in which said coupling retaining member encircles said elongated coupling section and has a longitudinally-extending slot between the walls of which said spring arm is located, said slot being open to said elongated coupling section and the outside thereof being closed at the rear end thereof to form an aperture through which said spring arm passes, the outer surface of said aperture being spaced from the spring arm in the forward position of the coupling retaining member with respect to said body portion, said cam surface on the elongated coupling section projects into said slot and inclines outwardly and rearwardly from the elongated coupling section, and said detent is an inwardly extending hook on said free end of the spring arm.
7. A removable attachment for a hand appliance for body care having an output member and an outwardly extending detent member transversely spaced from the output member, said attachment comprising a. a body portion having a working head toward the front end thereof and an elongated coupling section at the rear end thereof adapted for coupling with said output member of the hand appliance, b. a coupling retaining member slidably mounted on said elongated coupling section for movement therealong, c. said coupling retaining member including a spring arm extending longitudinally of said elongated coupling section with the rear end free for flexible movement outwardly from the elongated coupling section, d. said coupling retaining member encircling said elongated coupling section and having a longitudinally extending slot between the walls of which said spring arm is located, e. said slot being open to said elongated coupling section and the outside thereof being closed at the rear end thereof to form an aperture through which said spring arm passes, f. the outer surface of said aperture being spaced from the spring arm in the forward position of the coupling retaining member with respect to said body portion, g. a detent in the form of an inwardly-extending hook on the inner side of said free end of the spring arm for engaging said outwardly-extending detent member of the hand appliance, h. cooperating cam surfaces on said elongated coupling section and said spring arm, respectively, for moving said free end outwardly from the detent position thereof upon relative movement which increases the distance of the coupling retaining member from said working head, i. said cam surface on the elongated coupling section projecting into said slot and inclining outwardly and rearwardly from the elongated coupling section, j. and stop means for limiting said relative movement including a recess on the inner side of said spring arm and a projection on said elongated coupling section extending into said recess and adapted to abut against at least one end of said recess to provide a corresponding stop.
