1. Field of the Invention
The present invention relates to a hinge, and more particularly to a hinge that is compact and can hold a monitor securely at an optimum angle even after a long-term of use.
2. Description of Related Art
A conventional hinge is mounted between a base and a monitor of a portable electronic device and allows the monitor to rotate relative to the base for convenience of use.
Furthermore, the conventional hinge is designed to have a monitor-positioning function that helps the monitor of the portable electronic device to hold at an optimum angle to facilitate users to watch. However, the conventional hinge having monitor-positioning function is generally constructional complicated and bulky. Moreover, deformation may occur in the components of the hinge after a long-term of use and gradually cause the hinge to lose the ability of securely holding the monitor.
To overcome the shortcomings, the present invention provides a hinge to obviate or mitigate the aforementioned problems.
The main objective of the present invention is to provide a hinge that is compact and can hold a monitor securely at an optimum angle even if after a long-term of use.
To achieve the objective, the hinge in accordance with present invention comprises a body, a pivoting member, a first positioning element, a second positioning element and a resilient element.
The body is adapted to be mounted in a base of a portable electronic device and has a pivoting hole.
The pivoting member is adapted to be mounted in a monitor of the portable electronic device and has a pintle that mounted rotatably through the pivoting hole of the body and therefore allows the monitor to pivot relative to the base.
The first positioning element is movably mounted on the pintle of the pivoting member and has a rear surface, a front surface and a groove formed inclinedly in the front surface at an angle.
The resilient element is mounted around the pintle and has an end abutting and pushing the first positioning element toward the second positioning element.
The second positioning element is mounted securely on the pintle of the pivoting member, is simultaneously rotated with the pintle and has a rear surface corresponding to the front surface of the first positioning element and a rib formed diametrically on the rear surface. The rib corresponds to and selectively engages with the groove in the first positioning element to retain the pivoting member at a determined angle.
With such an arrangement, the hinge in accordance with present invention is compact and simple in structure. Moreover, with the resilient element assisting the positioning elements to engage with each other, the hinge effectively ensures the monitor being securely held at an optimum angle even after a long-term of use.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The body (10) is mounted securely in a base (81) of a portable electronic device (80), is elongated and has two ends, a mounting tab (13), a receiving slot (12) and multiple fixing holes (1). The mounting tab (13) is perpendicularly formed on one of the ends of the body (10) and has a pivoting hole (130) formed through the mounting tab (13) and two engaging notches (131). The engaging notches (131) are formed in the inner edge of the pivoting hole (130), communicate with the pivoting hole (130) and are diametrically opposite to each other. The receiving slot (12) is formed longitudinally through the body (10) and has a length. The fixing holes (11) are separately formed through the body (10) for securing the base (81) with fasteners.
The pivoting member (20) is mounted securely in a monitor (82) of the portable electronic device (80), is mounted rotatably on the body (10) and has a mounting portion (21) and a pintle (23). The mounting portion (21) has multiple securing holes (210) and a fixing tab (22) mounted securely to the mounting portion (21) with fasteners extending through the fixing tab (22) and the securing holes (210) in the mounting portion (21). The fixing tab (22) has multiple fixing holes (220) for securing the monitor (82) with fasteners. The pintle (23) is mounted rotatably through the pivoting hole (130) of the body (10), is non-circular in cross section and has a threaded end (230).
With further reference to
The first positioning element (60) is movably mounted on the pintle (23) of the pivoting member (20), moves along the pintle (23) and has a rear surface, a front surface, a bottom, a plank (61) and a groove (62). The plank (61) protrudes from the bottom of the first positioning element (60), is received in the receiving slot (12) of the body (10) to allow the first positioning element (60) to move but not rotate relative to the body (10) and additionally limits the moving travel of the first positioning element (60). The groove (62) is formed inclinedly in the front surface of the first positioning element (60) at an angle relative to the body (10).
The second positioning element (50) is mounted on the pintle (23) of the pivoting member (20) and has a rear surface, a front surface, a center, an engaging hole (51) and a rib (52). The rear surface corresponds to the front surface of the first positioning element (60). The engaging hole (51) formed through the center of the second positioning element (50), is non-circular in cross section and engages with the pintle (23) so as to make the second positioning element (50) simultaneously rotating with the pintle (23). The rib (52) is formed diametrically on the rear surface and corresponds to and selectively engages with the groove (62) in the first positioning element (60) to retain the pivoting member (20) in a determined angle based on the inclined groove (62).
With further reference to
The fixing element (40) may be a nut, is screwed onto the threaded end (230) of the pintle (23) and holds the first retaining element (31), the second retaining element (32), the first positioning element (60), the second positioning element (50) and the resilient element (70) on the pintle (23).
The washer (41) is mounted on the pintle (23) between the fixing element (40) and the second positioning element (50) to prevent abrasion.
With reference to
Accordingly, the hinge in accordance with present invention is compact and simple in structure. Moreover, with the resilient element (70) assisting the positioning elements to engage with each other, the hinge effectively ensures the monitor (82) being securely held at an optimum angle relative to the base (81) even if after a long-term of use.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
