Binding machine
View Patent ↗A punching and binding machine used to bind sheets to discs. The machine may include a lever with a first arm, a second arm, and a third arm. Each arm may be pivotally and slidably connected to minimize the force required by a user to punch cutouts in a stack of sheets. The lever may include a flipper connected to a binding member to actuate punching and binding simultaneously.
1. A hole punch, comprising:
a base;
a plurality of punching devices arranged along a longitudinal axis of the base and configured to punch cutouts along an edge of a sheet of paper, such that a cutout is formed at the edge of the sheet of paper, wherein at least a portion of the cutout has a width wider than a width of the cutout measured at the edge;
a lever to actuate the plurality of punching devices, the lever including:
a first arm having a first end pivotally connected to a first side of the base;
a second arm having a first end pivotally connected to a second side of the base and a second end slidably connected to an underside portion of the first arm; and
a third arm having a first end pivotally connected to the second side of the base, wherein the first arm has a second end slidably connected to an underside portion of the third arm, and
wherein the hole punch is fastened to a binding machine, the binding machine comprising a binding member configured to bind the sheet of paper to a plurality of discs, wherein the lever simultaneously activates the punching devices and the binding member.
2. The hole punch of claim 1 , further comprising a flipper to connect the lever to the binding member.
3. The hole punch of claim 2 , wherein the flipper comprises a torsion spring.
4. A punching and binding machine for assembling presentations, comprising:
a chassis;
a punching device configured to punch at least one cutout along an edge of a sheet,
wherein at least a portion of the at least one cutout has a width wider than a width of the cutout measured at the edge;
a disc rack carriage for holding at least one disc having a raised periphery, the raised periphery adapted to be received in the at least one cutout;
a binding member configured and arranged to press a portion of the sheet surrounding the at least one cutout onto the raised periphery of the at least one disc;
a lever configured to actuate the punching devices and the binding member simultaneously; and
a flipper to connect the lever to the binding member; and
a torsion spring in the flipper.
5. The punching and binding machine of claim 4 , wherein the disc rack carriage comprises at least one slot for holding the at least one disc.
6. The punching and binding machine of claim 5 , wherein the at least one slot is made of a rubber material.
7. The punching and binding machine of claim 4 , wherein the disc rack carriage comprises an angled front edge.
8. The punching and binding machine of claim 4 , wherein the disc rack carriage comprises a paper stop.
9. A punching and binding machine for assembling presentations, comprising:
a chassis;
a punching device configured to punch at least one cutout along an edge of a sheet,
wherein at least a portion of the at least one cutout has a width wider than a width of the cutout measured at the edge;
a disc rack carriage for holding at least one disc having a raised periphery, the raised periphery adapted to be received in the at least one cutout;
a binding member configured and arranged to press a portion of the sheet surrounding the at least one cutout onto the raised periphery of the at least one disc; and
a lever configured to actuate the punching devices and the binding member simultaneously, wherein the lever comprises:
a first arm having a first end pivotally connected to a first side of the chassis;
a second arm having a first end pivotally connected to a second side of the chassis and a second end slidably connected to an underside portion of the first arm; and
a third arm having a first end pivotally connected to the second side of the chassis, wherein the first arm has a second end slidably connected to an underside portion of the third arm.
10. The punching and binding machine of claim 4 , wherein the chassis comprises tracks to slideably guide the disc rack carriage between a loading position and a binding position.
11. The punching and binding machine of claim 4 , wherein the disc rack carriage comprises a handle.
12. The punching and binding machine of claim 4 , wherein the binding member comprises a protrusion configured to move within a guiding slot of the chassis.
13. The punching and binding machine of claim 4 , further comprising sheet alignment members to accommodate different sized sheets.
14. The punching and binding machine of claim 4 , wherein the binding member comprises binding fingers configured to displace between two or more discs held in the disc rack carriage.
15. The punching and binding machine of claim 14 , wherein the binding fingers comprise bottom curved surfaces.
16. The punching and binding machine of claim 4 , wherein the binding member comprises a rod that rides within a channel of the chassis, wherein the rod and channel are arranged in a direction of a binding action.
17. The punching and binding machine of claim 4 , wherein the flipper contacts and slides within an upper recess of the binding member to actuate the binding member when the lever is compressed.
