Detailed Description of the Preferred Em]bodiments
Referring to Fig. 1, a pair of hairdressing scissors 1 in accordance with
the present invention generally comprises two cutting members 11 and 12 that
are
pivoted together by a pivot 10. Each cutting member 11, 12 includes a handle
13
on an end thereof and a blade (not labeled) on the other end thereof, with
each
handle 13 having an opening 131 for the thumb or index finger of the user.
Each handle 13 has a first groove 132 in a first side thereof and a second
groove 133 in a second side thereof. Preferably, the first groove 132 has a
depth
equal to that of the second groove 133. A magnetic member 14 is mounted in the
IO respective first groove 132, with a portion of the magnetic member 14 being
exposed outside the handle 13 (see the exposed portion 141 in Fig. 1 ). In
this
embodiment, the respective magnetic member 14 has a thickness twice as the
depth of the groove 132, 133. Alternatively, the respective magnetic member 14
has a thickness that is the sum of the depth of the first groove 132 and the
depth
of the second groove 133 in a case that the depth of the second groove 133
differs
from that of the first groove 132. Thus, the exposed portion 141 of the
respective
magnetic member 14 of a pair of hairdressing scissors 1 is fittingly received
in the
respective second groove 133 of another pair of hairdressing scissors 1,
thereby
connecting the two pairs of hairdressing scissors 1 together. By repeating
this
connecting operation, plural pairs of hairdressing scissors 1 can be connected
together, as shown in Fig. 2. Since the cutting members 11 and 12 are
generally
made of steel or the like, the magnetic members 14 provide attraction for
preventing disengagement of two adjacent pairs of hairdressing scissors unless
a
relatively large force is applied to overcome the magnetic attraction and the
engaging force between the magnetic members 14 and the peripheries delimiting
the first and second grooves 132 and 133.

Fig. 3 illustrates a second embodiment of the present invention, wherein a
frame ring 15 made of less rigid material is mounted between the respective
magnetic member 14 and the periphery delimiting the respective first groove
132.
The material of the frame ring 15 is selected to assist in insertion of the
respective
magnetic member 14 into the respective first groove 132 without adversely
affecting magnetic attraction provided by the magnetic member 14.
Fig. 4 illustrates a third embodiment of the present invention. More
particularly, a pair of hairdressing scissors 2 in accordance with the third
embodiment of the present invention generally comprises two cutting members 21
and 22 that are pivoted together by a pivot 20. Each cutting member 21, 22
includes a handle 23 on an end thereof and a blade (not labeled) on the other
end
thereof, with each handle 23 having an opening 231 for the thumb or index
finger
of the user.
Each handle 23 has a through-hole 232 in which a magnetic member 24 is
securely mounted. The respective magnetic member 2 has a thickness equal to a
depth of the respective through-hole 232. Thus, two pairs of hairdressing
scissors
2 can be easily connected together through mutual attraction of the magnetic
members 24 respectively of the two pairs of hairdressing scissors 2.
Detachment
of the two pairs of hairdressing scissors 2 can be easily accomplished by
applying
a force sufficiently large to overcome the magnetic attraction between the
magnetic members 24. Thus, the user may combine plural pairs of hairdressing
scissors according to need. Fig. 5 illustrates connection of plural pairs of
hairdressing scissors in Fig. 4.
Fig. 6 illustrates a fourth embodiment of the present invention, wherein a
frame ring 25 made of less rigid material is mounted between the respective
magnetic member 24 and the periphery delimiting the respective through-hole
s
CA 02455213 2004-O1-14
232. The material of the frame ring 25 is selected to assist in insertion of
the
respective magnetic member 24 into the respective through-hole 232 without
adversely affecting magnetic attraction provided by the magnetic members 24.
Fig. 7 illustrates connection of plural pairs of hairdressing scissors in Fig.
6.
Fig. 8 illustrates a fifth embodiment of the present invention that is
modified from the first embodiment shown in Figs. 1 and 2. In this embodiment,
the thickness of the respective magnetic member 14 is greater than the sum of
the
depth of the first groove 132 and the depth of the second groove 133 so that
two
adjacent pairs of hairdressing scissors 1 are spaced apart from each other.
Thus,
the overall hairdressing scissor assembly consisting of plural pairs of the
hairdressing scissors can be used to perform special cutting techniques. The
spacing between two adjacent pairs of hairdressing scissors 1 can be altered
according to need. Alternatively, the spacing may not be uniform throughout
the
hairdressing assembly. For example, the spacing between the first pair of
hairdressing scissors 1 and the second pair of hairdressing scissors can be
different from that between the second pair of hairdressing scissors and the
third
pair of hairdressing scissors.
Although not specifically shown in the figures, in the hairdressing
scissors shown in Figs. 4 through 7, the respective magnetic member 14 may
have
a thickness greater than the depth of the respective through-hole 232 without
adversely affecting its function.
Fig. 9 illustrates a sixth embodiment of the present invention modified
from the third embodiment shown in Figs. 4 and 5. Fig. 10 illustrates
connection
of plural pairs of hairdressing scissors in Fig. 9. In this embodiment, the
respective magnetic member 24 has a thickness equal to the depth of the
respective through-hole 232, and the respective magnetic member 24 is
partially

CA 02455213 2004-O1-14
inserted into the respective through-hole 232, with an exposed portion 241 of
the
respective magnetic member 24 of the pair of hairdressing scissors 2 being
engaged in a through-hole 232 of another pair of similarly constructed
hairdressing scissors 2, best shown in Fig. 10.
S Although the invention has been explained in relation to preferred
embodiments, it is to be understood that many other possible modifications and
variations can be made without departing from the scope of the invention as
hereinafter claimed.
