1. Field of Invention
The present invention relates to a linear hinge, and more particularly to a linear hinge that is sturdy to prolong a utility life.
2. Description of the Related Art
A linear hinge is usually mounted between two appliances and pivots to change relative positions between the two appliances. With reference to
To overcome the shortcomings, the present invention provides a linear hinge to mitigate or obviate the aforementioned.
The primary objective of the present invention is to provide a linear hinge that is sturdy to prolong a utility life.
To achieve the objective, a linear hinge has a utility life, a sleeve, a bar and a pintle. The sleeve is tubular and has a mounting protrusion. The bar is mounted in the sleeve and has one end and a mounting recess corresponding to and engaging the mounting protrusion. The pintle has an outside rod and inside rod. The inside rod is mounted rotatably in the sleeve and has an end and an outer surface. The bar further comprises a positioning hole formed in the end of the bar and the inside rod of the pintle further comprises a positioning stub extending from the end of the inside rod and corresponding to and mounted in the positioning hole of the bar. Therefore, the pintle is held in the sleeve without axially departing from the sleeve and is sturdy when the pintle pivots. Thus the utility life of the hinge will be prolonged.
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
With further reference to
The bar (1) is mounted in the sleeve (2) and has an end, multiple pivot holes (11) and a mounting recess (12). The pivot holes (11) is formed through the bar (1) and provides multiple holding elements to extend through and mount in to connect to one of the appliances. The mounting recess (12) is formed longitudinally in the bar (1) and corresponds to and engages the mounting protrusion (21) so the bar (1) and the sleeve (2) connect to each other firmly.
The pintle (3) has an outside rod (30) and an inside rod (32). The outside rod (30) has multiple pivot through holes (31) formed through the outside rod (30) and providing multiple holding elements to extend through and mount in to connect to the other appliance. The inside rod (32) is mounted rotatably in the sleeve (20) and has an end , an outer surface and an optional oil groove (35). The oil groove (35) is formed around the outer surface of the inside rod (32) of the pintle (3).
The improvement of the hinge is the bar (1) further comprising a positioning hole (13) formed in the end of the bar (1) and the inside rod (32) of the pintle (3) further comprising a positioning stub (33) extending from the end of the inside rod (32) and corresponding to and mounted in the positioning hole (13) so the pintle (3) protrudes into the sleeve (2) and the bar (1).
With further reference to
Because the positioning stub (33) of the pintle (3) is held in the positioning hole (13) in the bar (1), the pintle (3) is held in the sleeve (2) and the bar (1) without axially departing from the sleeve (2) and the bar (1) and is sturdy when the pintle (3) rotates and the utility life of the hinge will be prolonged.
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, and 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.
