FIELD OF THE INVENTION
- BACKGROUND OF THE INVENTION
The invention relates to the handle structure of a portable electronic device, and more particularly to the handle structure of a notebook computer for industrial or military purposes. The tilt angle of the handle can be adjusted and held in the new angle by its retaining structure.
At present, notebook computers are divided into two usage types, that is, general notebook computers, and notebook computers for industrial or military purposes (these kinds of electronic devices are referred to in the preferred embodiment and are explained, though it is to be understood that the invention is not limited thereto). An industry-oriented notebook computer is always used in a factory. For ease of use, it is seldom carried in a backpack. Usually, it is protected by a case much stronger than that of an ordinary notebook computer, and it is equipped with a handle for carrying.
Handles used to be only pivotally connected to a notebook computer. Hence, the angle at which a handle is held varies with the position of the center of gravity of the notebook computer. In addition, there is no fixation mechanism, so the handle has to be held at different angles for different positions of the center of gravity of the notebook computer, leading to great inconvenience.
Therefore, a user has little control over the angle at which the handle is held. In the event that the handle lies so close to the notebook computer connection ports that it gets in their way, it will prevent the connection ports from connecting to any peripheral device.
- OBJECT AND SUMMARY OF THE INVENTION
In view of this, to meet the users' demands it is necessary to design a mechanism for the rotation and positioning of a handle, so that it will be easy to hold the handle without hindering the connection of a connection port and a peripheral device.
The primary object of the invention is to provide a handle structure for an electronic device, so that a user may adjust the angle at which the handle is held and fix the handle at a specific angle.
The handle structure of electronic device disclosed by the invention comprises a handle, a base, a connector and a fastener. The base is installed beside the electronic device. The handle is fixed on the base and is able to rotate by means of the connector that passes through the holding hole of the base. There is a plurality of grooves on the circumferential surface of the connector. Corresponding to the grooves is the fastener inside the base. Through a spring piece, the fastener has at least one locking position in the normal state wherein it sticks into a groove so as to lock the handle, as well as one released position wherein it releases from the groove to allow the handle to rotate and change angles.
Whenever a user needs to adjust the angle at which the handle is held, the user may turn the handle so as to rotate the connector inside the base. When the rotation of the connector is stopped at the intended angle, the fastener inside the base locks in the groove of the connector because of the compression of the spring inside the base. In this way, the object of angle adjustment and fixation of the handle is achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 7 shows how to rotate the handle of the invention to an angle and fix the handle at the angle.
As shown in FIGS. 1 and 2, the handle structure of electronic device disclosed by the invention comprises a handle 10 and a pair of bases 20. At each of the two ends of the base 20 are two through holes 23 & 23′. The pair of bases 20 is fixed on the notebook computer 70 by screws 26. The handle 10 is fixed to the pair of bases 20, as the connectors 30 insert into the holding holes 21 of the bases 20. There is a plurality of grooves 31 on the circumferential surface of the connectors 30 pivotally connected to the bases 20. The grooves 31 of the connector 30 may turn in a circle within the holding hole 21. The distance between any two grooves 31 determines the amount of angle adjustment for handle positioning.
As shown in FIGS. 3A and 3B, the holding hole 21, by which the base 20 and the connector 30 are connected, is equipped with a positioning hole 22. Inside the positioning hole 22 are the fastener 40 and the spring 50. At the open end of the positioning hole 22 is an intra-hexagonal screw 60 for the purpose of locking and fixing, so that the spring 50 presses on the fastener 40. When the handle 10 is rotated, it turns the connector 30 as well. As a result, the fastener 40 has at least one locking position in the normal state wherein it sticks into a groove 31 to lock the handle 10, as well as one released position wherein it releases from the groove 31 to allow the handle 10 to rotate and change angles.
Inside the positioning hole 22, the spring 50 presses on the fastener 40 and makes the fastener 40 lock in a groove 31 of the connector 30, so that the handle 10 is fixed at a specific angle.
The aforesaid embodiment shows that, as put forth by the invention, the base 20 is fixed in the proper position of the notebook computer 70 by two screws 26. Thus the fixing mechanism is not limited to the intra-hexagonal screw 60 illustrated in the aforesaid drawing. Instead, any fixation mechanism that can do the same job will suffice. For example, as shown in FIG. 5, one end of the base 20 has a rivet 24, whereas the other end of the base 20 has a through hole 23. The base 20 is fixed on the proper position of the notebook computer 70 by the rivet 24 first. Then the base 20 is locked on the notebook computer 70 with a screw 26. This not only reduces the assembly time but also makes the invention easier to operate.
By the same token, there is a plurality of types for the groove 31 of the connector 30 to lock in the fastener 40 in a smooth manner. As shown in FIGS. 4A-4D, the transverse profile of the groove 31 can be round (see FIG. 4A), square (see FIG. 4B), V-shaped (see FIG. 4C) or dovetailed (see FIG. 4D). The aforesaid fastener 40 may also, by means of a pin 25 (see FIG. 6), achieve its fastening function as well as the aforesaid fastening mechanism or other equally effective fastening mechanisms.
Handles 10 used to be only pivotally connected to a notebook computer 70. The handle 10 thus swung uncontrollably whenever the position of the center of gravity of the notebook computer 70 changed, causing inconvenience for holding. In addition, being merely pivotally connected to a base 20 without any fixing mechanism, the handle 10 may get too close to the connection ports 701 found behind the notebook computer 70. If the notebook computer 70 is rested on the dock 71, the handle 10 may also get too close to the notebook computer 70 and the connection ports 701 of the dock 71, preventing the connection of the connection ports 701 and other peripheral devices.
As shown in FIG. 7, the handle structure of the electronic device disclosed by the invention comprises a handle 10 and bases 20 found at both ends of the handle 10. The bases 20 are installed in suitable positions near the connection ports 701 behind the notebook computer 70, for users to hold and carry the notebook computer 70.
When the handle 10 can be fixed at a specific angle, it may be fixed to the other side opposite the connection ports 701, so that it will not get too close to the connection ports 701. Whenever the handle 10 rotates, it also turns the connector 30. Turn the handle 10 to a required angle, and the spring 50 presses the fastener 40 which, in turn, locks into a groove 31 of the connector 30. Being fixed to the side opposite the connection ports 701, the handle 10 does not hinder the connection of the connection ports 701 and other peripheral devices. The angle adjustment and fixation of the handle 10 also enables a user to work with the notebook computer 70 in a comfortable, convenient manner when the notebook computer 70 is slanted at a specific angle.
Since the distance between any two grooves 31 of the connector 30 determines the rotation angle, the angle at which the handle 10 is held can be adjusted and fixed. Hence, the handle 10 becomes more convenient to hold, and it may not swing in an uncontrollable manner when the center of gravity of the notebook computer 70 changes. In addition, the handle 10 may not get too close to the connection ports behind the notebook computer 70 to hinder the connection of the connection ports 701 and other peripheral devices.
The Effects Attained
The handle structure of electronic device disclosed by the invention has the following effects:
Users may fix the handle at an intended angle. The advantages are: the handle does not swing when the center of gravity of the notebook computer changes; it becomes easier and more convenient to hold the handle, avoiding any damage to the internal equipment of the notebook computer due to unnecessary vibration of the notebook computer. In addition, if users want to connect a peripheral device to one of the connection ports, the handle may be fixed to the opposite side of the connection ports so as to stay free of the connection port, making the connection process easier and faster.
