Abstract

A pair of scissors having a pair of blades which are slidingly fitted between a pair of handles which are pivotally supported one on the other. The blades are drawn out when the scissors are used, and they are accommodated between the handles when the scissors are not used, thus enabling the scissors to be easily carried.

Claims

1. A pair of scissors comprising:

a pair of handles, first pivot means for pivotally connecting said pair of handles together, a pair of blades, second pivot means for pivotally connecting together said pair of blades, sliding means for mounting said blades between said handles for movement between a retracted and an extended position, a spring engaging said blades to bias said blades to the open position when said blades are in the extended position, and projections on each one of said pair of handles engageable with a respective one of said blades for operating said blades about said second pivot means when said handles are pivoted with respect to each other about said first pivot means.

2. A pair of scissors according to claim 1, further comprising:

a slit formed in one of said handles near the top end thereof, said slit extending in the same direction as that in which said one of said handles pivots relative to the other one of said handles; and

a guide member having a head whose outside diameter is larger than the width of said slit, said guide member being formed on said other one of said handles so as to project therefrom to pass through said slit.

3. A pair of scissors according to claim 1, further comprising a pair of slits formed in the backs of said pair of blades, said pair of slits being engaged with the opposite ends of said spring for extending said blades.

4. A pair of scissors according to claim 1, further comprising:

an accommodation gap open at the top of said handles, said accommodation gap being formed in one of said pair of handles between a pair of contacting projections one of which constitutes one of said contacting projections and which extend from an inner part of said accommodation gap to the opening thereof such as to be parallel with each other, said pair of blades being fitted into said slid between said pair of contacting projections, one of said pair of contacting projections having a slanted portion which increases the longitudinal dimension of said opening of said accommodation gap;

a top contacting projection which constitutes the other one of said contacting projections formed on said other one of said pair of handles and which contacts one of said blades on the side of said slanted portion;

elongated holes respectively formed in said pair of handles, said elongated holes engaging with the main pivot shaft of said blades; and

an engaging edge formed at the top of one of said elongated holes of said other one of said handles such as to be recessed at the side thereof opposite to that of said top contacting projection, said engaging edge being engaging with said main pivot shaft.

5. A pair of scissors according to claim 1, wherein a support shaft which pivotally supports said pair of handles is disposed at the rear of said pair of blades.
