Definitions

  • This invention relates to a lever arch mechanism.
  • a lever arch mechanism is stationery widely used for retaining pages such as loose-leaf pages.
  • Chinese Patent No. 01124645.6 owned by the present applicant disclosed a lever arch mechanism comprising a substantially flat substrate; two first ring members separated from each other and having an end fixedly attached onto one longitudinal side of the substrate, the first ring members extending generally vertically upwards from the substrate and bent slightly at their other end to form a bending portion; two second ring members separated from each other and having an end movably attached onto the other longitudinal side of the substrate, the second ring members extending generally vertically upwards from the substrate and bent slightly at the other end to form the other bending portion, thereby forming a closed loop by engagement with the bending portion on the other end of two first ring members when the lever arch mechanism is closed, two second ring members connected integrally with each other at their ends near the substrate by a connecting portion to allow two second ring members move together, the connecting portion having a generally U-shaped bending portion bent at its middle portion towards the center of the substrate; a generally
  • the roller By pressing and rotating the lever downward, the roller may resist against the upward pushing force of the leaf spring and move along a direction away from the lever handle to a position where the connecting portion presses against the substrate, thereby moving two second ring members together to a position where two second ring members contact with two first ring members that are attached fixedly to form a close loop respectively.
  • the roller By rotating the lever upward and away from the substrate, the roller may move along a direction towards the lever handle to a position where it is possible to release the pressing against the connecting portion, so that the connecting portion may move away from the substrate under the action of the upward pushing force of the leaf spring, thereby moving two second ring members together and away from two first ring members to form an opened loop respectively.
  • the lever arch mechanism is opened.
  • the lever arch mechanism may be closed by pressing and rotating the lever downward, and the lever arch mechanism may be opened by rotating the lever upward and away from the substrate.
  • the lever arch mechanism when the lever arch mechanism is opened, the lever is at an upward-raised position and occupies a gap between two ring members facing to each other, thereby interfering with accessing loose-leaf pages and resulting in much inconvenience for accessing loose-leaf pages.
  • the present invention is proposed in consideration of the conventional lever arch mechanism.
  • one object of the invention is to provide a lever arch mechanism in which the lever does not occupy the gap between two ring members facing to each other when the lever arch mechanism is opened, thereby facilitating accessing loose-leaf pages.
  • a lever arch mechanism comprising:
  • the lever mechanism since the lever mechanism is arranged to close the lever arch mechanism by rotating the lever mechanism upwards and away from the substrate, and to open the lever arch mechanism by rotating the lever mechanism downwards and toward the substrate, the lever mechanism is more close to the substrate when the lever arch mechanism is opened, thereby substantially not occupying the gap between two ring members facing to each other and being very convenient for accessing the loose-leaf pages.
  • Figs.1 to 7 show a lever arch mechanism 100 according to a first embodiment of the invention.
  • the lever arch mechanism 100 according to the invention comprises a generally flat substrate 101.
  • Two first ring members 103 that are separated from and parallel with each other are attached fixedly onto a longitudinal side of the substrate 101.
  • Two first ring members 103 substantially extend vertically upwards from the substrate 101 and are bent slightly at their free ends to form a bending portion respectively.
  • a ring assembly 105 is attached movably onto the other longitudinal side of the substrate 101.
  • the ring assembly 105 comprises two second ring members 105a that are separated from and parallel with each other and a connecting portion 105b for connecting integrally two second ring members 105a.
  • Each of two second ring members 105a has a bending portion formed on its free end respectively to allow two second ring members 105a of the ring assembly 105 to engage with the corresponding one of two first ring members 103 that are attached fixedly onto the substrate 101 to form a closed loop.
  • Two second ring members 105a of the ring assembly 105 are connected integrally with each other at their other ends near the substrate 101 by the connecting portion 105b.
  • the connecting portion 105b has a generally U-shaped bending portion 105c bent substantially horizontally at its middle towards the center of the substrate, and the middle of the bending portion 105c protrudes slightly upward to form a protrusion 105d.
  • the first ring members 103 and the ring assembly 105 have a generally circular or elliptical cross section respectively, and are made from suitable materials such as steel.
  • the ring assembly 105 is attached movably onto the substrate 101 by two turned-over portions 107. Two turned-over portions 107 are formed on one side of the substrate 101 provided with the ring assembly 105 by cutting or punching the substrate and turning the cut or punched portions of the substrate over.
  • a generally upstanding projection 109 is substantially formed in the middle of the substrate 101 by cutting or punching the substrate 101 near the ring assembly 105 and bending the cut or punched portions of the substrate upwards from the substrate.
  • a cutout 111 is left in the substrate 101 because the projection 109 is bent upwards.
  • An elongated slot 113 is formed in the longitudinal side of the substrate provided with the ring assembly 105, and its function will be described later.
  • One or more holes 115 may also be formed in the substrate for attaching the lever arch mechanism onto such as those of files or notebooks.
  • the lever arch mechanism 100 further comprises a lever 117.
  • the lever 117 comprises a lever body 117a, a lever head 117b extending obliquely and downwards from one end of the lever body 117a and a lever handle (operation end) 117c extending obliquely and downwards from other end of the lever body 117a.
  • the lever arch mechanism 100 according to the invention also comprises a roller 119 which is preferably made from plastics. The roller 119 is attached onto the free end of the lever head 117b through a pin shaft 121.
  • two first ring members 103 are mounted fixedly on one longitudinal side of the substrate 101 by a connection such as rivets, welding or any other known connection means.
  • Two ends of the connecting portions 105b of the ring assembly 105 are fixed movably by two turned-over portions 107 so that the ring assembly 105 is attached movably onto the substrate 101.
  • the U-shaped bending portion 105c of the connecting portions 105b substantially locates near the projection 109 to movably attach the ring assembly 105 onto other longitudinal side of the substrate 101 so that two second ring members 105a of the ring assembly 105 align with two first ring members 103 attached fixedly.
  • the lever 117 provided with the roller 119 is attached rotatably onto the projection 109 at a joint 117d between the lever body 117a and the lever head 117b by a fastener 123 such as a rivet so that the roller 119 may move substantially on the bending portion 105c of the ring assembly 105.
  • a leaf spring 125 is bended slightly into a generally arcuate shape, with one end of the leaf spring 125 inserted into the elongated slot 113 of the substrate 101 to be retained on the substrate 101, with other end located below the bending portion 105c of the ring assembly 105 and abutting resiliently against the bending portion 105c of the ring assembly 105 for pushing the bending portion 105c of the ring assembly 105 upwards by its resilience.
  • the mounting position of the leaf spring 125 is not limited to the illustrated position as long as the leaf spring 125 can abut against the underside of the bending portion 105c.
  • the shape of the leaf spring 125 also is not limited to the illustrated shape as long as the leaf spring 125 can abut against the underside of the bending portion 105c to generate an upward pushing force.
  • the lever head 117b may rotate counterclockwise around the fastener 123 from the state shown in Fig.5 , thereby moving the roller 119 mounted onto the lever head 117b to the protrusion 105d along the bending portion 105c of the ring assembly 105 in a direction towards the lever handle 117c, and pressing the connecting portion 105b onto the substrate 101 against the upward pushing force of the leaf spring 125.
  • two second ring members 105a of the ring assembly 105 move together to a position where they contact with two opposite first ring members 103 to form closed loops for retaining loose-leaf pages, as shown in Fig.2 .
  • the lever head 117b may rotate clockwise around the fastener 123 from the state shown in Fig.2 , thereby moving the roller 119 mounted onto the lever head 117b from the protrusion 105d along the bending portion 105c of the ring assembly 105 in a direction away from the lever handle 117c, and releasing the pressing of the connecting portion 105b onto the substrate 101.
  • the connecting portion 105b moves away from the substrate 101 under the action of the upward pushing force of the leaf spring 125 so that two second ring members 105a of the ring assembly 105 move from two first ring members 103 to form opened loops for accessing loose-leaf pages.
  • two stoppers 127a and 127b are formed on the projection 109 for limiting respectively the rotation ranges of the lever head 117b when the lever arch mechanism is closed and opened.
  • the stopper 127b limits the lever head 117b to a position where the lever arch mechanism is in the closed state.
  • a recess 105e is preferably formed on the bending portion 105c of the ring assembly 105 at one side of the protrusion 105d to which the roller 119 will move.
  • the recess 105e accommodates the roller 119 when the lever arch mechanism is opened. Both sides of the protrusion 105d may be provided symmetrically with recesses 105e for facilitating machining.
  • Figs.9 to 15 show the lever arch mechanism 200 according to a second embodiment of the invention.
  • the structure of the lever arch mechanism 200 according to the second embodiment of the invention is substantially similar to that of the lever arch mechanism 100 according to the first embodiment of the invention except the shape of the lever.
  • Parts of the lever arch mechanism 200 according to the second embodiment corresponding to parts of the lever arch mechanism 100 according to the first embodiment are indicated by the same reference numerals, plus "100". The description for the same parts will be omitted.
