Abstract

A sheet fastener for fastening a pair of sheet edges includes a first member and a second member. The first member includes a first fixing portion configured to engage a first edge of the pair of sheet edges and a holder continuous with the first fixing portion. The holder defines a first recess and includes a projection and a support portion that define an opening to the first recess. The second member includes a second fixing portion configured to engage a second edge of the pair of sheet edges and a head continuous with the second fixing portion. The head includes a front edge opposite from the second fixing portion and a head surface extending from the second fixing portion to the front edge. The head is insertable into the first recess such that a portion of the head surface maintains contact with the projection of the holder.

Claims (20)

1 . A sheet fastener for fastening a pair of sheet edges, the sheet fastener comprising:

a first member comprising:

a first fixing portion configured to engage a first edge of the pair of sheet edges; and

a holder continuous with the first fixing portion, wherein the holder defines a first recess and comprises a projection and a support portion, wherein the projection and the support portion define an opening to the first recess; and

a second member comprising:

a second fixing portion configured to engage a second edge of the pair of sheet edges; and

a head continuous with the second fixing portion, wherein the head comprises a front edge opposite from the second fixing portion and a head surface extending from the second fixing portion to the front edge, wherein:

the head of the second member is insertable into the first recess of the holder such that a portion of the head surface maintains contact with the projection of the holder,

the support portion of the holder extends from a connecting portion of the holder, and the projection of the holder extends from the connecting portion in a direction opposite from the support portion,

the first member includes a step portion between the first fixing portion and the holder and continuous with the first fixing portion and the holder, and

the step portion offsets the connecting portion of the holder such that an entirety of the holder is above or below the first fixing portion of the first member, and

the support portion includes a support portion edge, and the support portion edge contacts the second fixing portion.

2 . The sheet fastener according to claim 1 , wherein

a curvature of the head surface of the head is complementary to a curvature of a surface of first recess.

3 . The sheet fastener according to claim 1 , wherein

a second fixing surface of the second fixing portion extends in a second plane, and the front edge of the head is offset from the second plane such that a vertical gap is defined between the second plane and the front edge.

4 . The sheet fastener according to claim 1 , wherein

the second fixing portion includes an end of the second member, and the head is provided opposite from the end,

the second member includes a projection extending from the second fixing portion between the end and the head of the second member, and

a portion of the projection of the holder of the first member is received between the projection and the head of the second member when the second member is fully assembled with the first member.
