Scanners may have lids that cover a scanning surface. The lids may be attached to the scanners via hinges. In some examples, when the lids are pressed down on media having relatively large thicknesses, lateral forces may be exerted on the hinges.
Features of the present disclosure are illustrated by way of example and not limited in the following figure(s), in which like numerals indicate like elements, in which:
For simplicity and illustrative purposes, the present disclosure is described by referring mainly to examples. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be readily apparent however, that the present disclosure may be practiced without limitation to these specific details. In other instances, some methods and structures have not been described in detail so as not to unnecessarily obscure the present disclosure.
Throughout the present disclosure, the terms “a” and “an” are intended to denote at least one of a particular element. As used herein, the term “includes” means includes but not limited to, the term “including” means including but not limited to. The term “based on” means based at least in part on.
Scanners may have lids, such as lids for automatic document feeders (ADFs), that cover scanning surfaces. A lid may be rotatably coupled to the scanner, for instance, by a hinge mounted between the lid and a scanner bezel that may surround the scanning surface. In many of these instances, the lid and scanner bezel interface hinge designs may not support book scanning. For instance, during scanning, when the lid is closed over a document having a relatively large thickness, such as books, the lid may dislodge or be damaged under relatively low pressing forces, which may result in lateral forces to be exerted on the hinge.
Disclosed herein are apparatuses having an interlock hinge design that may provide structural support to the hinge, which may increase the amount of pressing forces that the lid may withstand. By way of particular example and for purposes of illustration, a hinge support assembly as described in the present disclosure may increase the allowable pressing force at the lid to be about 60N, compared to less than about 20N without the added support. The apparatuses disclosed herein may result in improved strength of the lid hinge, which in turn may reduce potential costs associated with repair/replacement of damaged scanner lids and/or hinges due to book scanning.
In some examples, an apparatus may include a body disposed around a scanning surface, a lid disposed to cover the scanning surface, a hinge disposed between the cover and the body to rotatably couple the cover to the body, and a hinge support assembly to provide structural support to the hinge. The hinge support assembly may include a first engagement member that extends from the cover and a second engagement member that extends from the body to engage with the first engagement member. The first engagement member may engage the second engagement member based on a position of the cover relative to the scanning surface. In some examples, the first engagement member may contact the second engagement member to restrict a lateral movement of the lid relative to the hinge.
Reference is first made to
In some examples, the apparatus 100 may include a body 102 on which a scanning surface 104 may be supported. The body 102 may be a bezel disposed around the scanning surface 104. The apparatus 100 may include a lid 106 to cover the scanning surface 104. A hinge 108, which may rotatably couple the lid 106 to the body 102, may be disposed at a distal end of the lid 106, for instance, at a side of the lid 106 near the back of the apparatus 100. The hinge 108 may be one of various types of hinges that may allow rotational movement of the lid 106 relative to the body 102.
In some examples, a hinge support assembly 200 may be disposed on the body 102. The hinge support assembly 200 may be positioned at the same side of the apparatus 100 as the hinge 108 to provide structural support to the hinge 108. In some examples, the hinge support assembly 200 may be positioned near a rotational axis of the hinge 108. The hinge support assembly 200 may include a first engagement member 110, which may extend from the lid 106, and a second engagement member 112, which may extend from the body 102.
In some examples, the lid 106 may have a section that extends down a side of the body 102. For instance, the lid 106 may include a section 106-1 that may extend down at the back of the apparatus 100. In some examples, the first engagement member 110 may be formed on the section 106-1 of the lid 106 that extends downward, as depicted in
In some examples, the first engagement member 110 may include a portion of the section 106-1 of the lid 106 that extends downward and a recess 114 formed on a surface of the section 106-1. When the lid 106 is in a closed position, the lid 106 may extend in a first direction, parallel with the scanning surface 104, and the first engagement member 110 may extend from the lid 106 in a second direction at a predetermined angle relative to the first direction, for instance, extend down from the lid 106 in a direction perpendicular to the scanning surface 104.
The recess 114 may face in the first direction toward the second engagement member 112 when the lid 106 is positioned in a closed position. In some examples, the recess 114 may be an opening formed through the section 106-1 of the lid 106, a cavity or a depression formed on a surface of the section 106-1, a hook or a catch having predetermined shape, and/or the like. For instance, the recess 114 may be an ‘L’ shaped section formed on the section 106-1.
In some examples, the first engagement member 110 may include a protrusion 116, which may extend from the section 106-1 of the lid 106 toward the second engagement member 112. The first engagement member 110 may include a first surface 118, which may be a contact surface to engage the second engagement member 112. In this regard, the first surface 118 may include a surface inside the recess 114 and/or a surface on the protrusion 116.
In some examples, the second engagement member 112 may include a portion of the section 102-1 of the body 102 that may extend down relative to the scanning surface 104 and a protrusion 120 that may extend from the section 102-1 of the body 102. In some examples, the second engagement member 112 may extend from the body 102 in the first direction, for instance, in an inward direction, toward the scanning surface 104. The second engagement member 112 may include a second surface 122, which may be a contact surface to engage with the first engagement member 110. In some examples, the second engagement member 112 may include a recess 124 formed on the section 102-1 of the body 102, which may accommodate the protrusion 116 of the first engagement member 110 when the lid 106 is in a closed position.
The first engagement member 110 may engage the second engagement member 112 based on movement of the lid 106 relative to the scanning surface 104. The first engagement member 110 may rotate relative to the second engagement member 112 based on movement of the lid 106, and when the lid 106 is positioned between a predetermined angle relative to the scanning direction and the closed position, the first engagement member 110 may be engaged with the second engagement member 112. In some examples, the first engagement member 110 may be engaged with the second engagement member 112 based on relative positions with each other, without physically touching each other.
In this regard, when the lid 106 is closed by more than the predetermined angle, the first engagement member 110 may be moved such that the first surface 118 of the first engagement member 110 is positioned to face the second surface 122 of the second engagement member 112. In some examples, the first engagement member 110 may be in an engaged position with the second engagement member 112 when the second engagement member 112 is positioned inside the recess 114 formed in the first engagement member 110.
When the lid 106 is positioned between the predetermined angle relative to the scanning surface 104 and an open position, the second engagement member 112 may disengage from the first engagement member 110. In these instances, the first surface 118 may be moved away from the second surface 122 and/or the second engagement member 112 may be positioned outside of the recess 114 formed in the first engagement member 110.
In some examples, in the engaged position as depicted
In this regard, the first engagement member 110 may be engaged with the second engagement member 112 through a range of angles of the lid 106 to accommodate various thicknesses of the media 126. The range of angles at which the first engagement member 110 and the second engagement member 112 may be engaged with each other may be based on various shapes and angles of the first surface 118 and/or the second surface 122. The shapes of the first engagement member 110 and/or the second engagement member 112, and/or the angles of the first surface 118 and the second surface 122 may be user-defined, or may be based on testing, modeling, simulations, and/or the like.
Reference is now made to
The hinge assembly 300 may include a hinge 108 to rotatably couple a lid 106 for a scanner to a body 102 of the scanner. A recess, such as the recess 114 depicted in
A protrusion 120 may extend from the body 102 and may have a second contact surface, such as the second surface 122 depicted in
When the lid 106 is in a closed position, as depicted in
When the lid 106 is positioned in an open position, as depicted in
When the lid 106 is positioned in an engaged position, as depicted in
Reference is now made to
The bezel 402 may be disposed around the scanning surface 404. The bezel 402 may be the same as the section 102-1 of the body 102 and the scanning surface 404 may be the same as the scanning surface 104, depicted in
A hook 410 and a protrusion to engage the hook 410, such as the protrusion 120 depicted in
The protrusion 120 may extend from the bezel 402 and may engage the hook 410 in response to movement of the lid 406 relative to the scanning surface 404. In this regard, the hook 410 may engage with the protrusion 120 to prevent lateral movement of the lid 406 relative to the hinge 408, for instance, due to the lid 406 being pressed down on a media 126 having a relatively large thickness.
In some examples, when the lid 406 is positioned between a predetermined angle relative to the scanning surface 404 and a closed position, the protrusion 120 may be positioned inside the hook 410 disposed on the surface of the lid 406. When the lid 406 is positioned between the predetermined angle relative to the scanning surface 404 and an open position, the protrusion 120 may be positioned outside of the hook 410 disposed on the surface of the lid 406.
In some examples, the hook 410 may have a first surface, such as the first surface 118 depicted in
