II. Description of the Prior Art
Please refer to
Further, a lid 2 is disposed on the casing 1 for precisely covering the opening 10, such that the casing 1 forms a closed space to prevent dust or foreign substances from entering the accommodating space 12. The lid 2 comprises a bent section 20 on at least one side, and the bent section 20 and the lid 2 are connected perpendicularly to each other, such that when the lid 2 is covered on the opening 10, the bent section 20 attaches precisely on the casing 1. At least one screw hole 22 is disposed respectively at the corresponding position on the bent section 20 and the casing 1, so that a user may use a tool to install a plurality of screws 3 into the screw holes 22 between the bent section 20 and the casing 1 to connect the lid 2 and the casing 1.
However, it requires a tool to remove the screws 3 from the lid 2 each time before removing the lid 2 from the casing 1 in order to expose the opening 10 for installing new electronic components into the accommodating space 12, or removing electronic components from the accommodating space 12, or directly repairing the electronic component inside. If the user does not have a tool handy, the lid 2 cannot be removed from the casing 1, and thus the user is unable to install, remove, or repair electronic components through the opening 10. Further, if the screw 3 is removed and installed very frequently, the teeth of the screw 3 will be worn out and the installation cannot be done. This arrangement causes trouble and inconvenience for the application.
In view of the conventional way of using screws to connect the lid and the casing of a computer, which causes inconvenience on installation, uninstallation, and maintenance, the inventor of this invention based on years of experience on the manufacture of related products to conduct extensive researches and experiments and finally invented a drawer-type computer casing in accordance with this invention.
The primary object of the invention is to provide a drawer-type computer casing, comprising a box and a sliding frame, wherein the box comprises an opening on one side, a connecting section disposed respectively on both corresponding sides of the opening, and an accommodating space in the box. The sliding frame can be accommodated in the accommodating space, and a latching member is movably coupled to on an end surface of the box at the position corresponding to the connecting section, such that when the sliding frame is installed into the accommodating space, the latching member will be set precisely on the corresponding position of the connecting section. Therefore, the latching member can be moved into the connecting section to connect the box and the sliding frame. Such arrangement provides a convenient way for installation and uninstallation without using screws to connect the box and the sliding frame.
The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:
Please refer to FIGS. 2 to 5 for the drawer-type computer casing of the present invention. The casing 4 of this invention comprises a box 5 and a sliding frame 6, wherein the box 5 comprises an opening 50 on one side, a connecting section 52 disposed respectively on both corresponding sides of the opening 50, and an accommodating space 54 in the box 5. The sliding frame 6 is accommodated in the accommodating space 54; a pulling handle 62 is disposed on an end surface 60; and a latching member 64 is movably coupled to on the edge of the end surface 60 proximate the connecting section 52, such that when the sliding frame 6 is pushed as if it were a drawer into the accommodating space 54, the latching member 64 will be set precisely on the corresponding position of the connecting section 52. Then, the latching member 64 can be moved into the connecting section 52 to connect the box 5 and the sliding frame 6.
Please refer to FIGS. 3 to 5 for a preferred embodiment of this invention. The latching member 64 further comprises a horizontal section 642 and a vertical section 644, wherein the horizontal section 642 is attached onto the end surface 60, and a protruded pillar 646 is disposed individually on both sides of the connecting section 52. A sliding track 602 is disposed individually on the positions where the end surface 60 and the protruded pillar 646 are in contact. These sliding tracks 602 are provided for sliding the protruded pillars 646 thereon and restricting the moving distance of the protruded pillars 646. The vertical section 644 is disposed at one end of the horizontal section 642 away from the connecting section 52 and is perpendicular to the horizontal section 642. By pushing the vertical section 644, the horizontal section 642 is driven and shifted such that the protruded pillar 646 moves along the sliding track 602 and further extends the latching member 64 into the connecting section 52. The sliding track 602 has a fixed groove 604 proximate both ends of the sliding track 602. By means of the protruding pillar 646 working together with the fixed groove 604, the latching member 64 will not collide at or detach from the connecting section 52 after the latching member 64 is extended into the connecting section 52. The latching member 64 is pushed away from the connecting section 52, and then it will not move arbitrarily.
Please refer to
Please refer to FIGS. 3 to 5 for the preferred embodiment of this invention. The end surface 60 has a groove 66 disposed at a position corresponding to the latching member 64 for accommodating the horizontal section 642, such that the horizontal section 642 and the end surface 60 are at the level of the same height.
The sliding track 602 is disposed in the groove 66 adjacent to both inner edges of the vertical section 644. A bumper 61 is disposed individually on both sides of vertical section 644 adjacent to the groove 66 and the bumper 61 is extended outward to the level of the same height of the vertical section 644, such that the vertical section 644 will not be collided by accident, which may shift the horizontal section 642.
Therefore, the sliding frame 6 will not be separated from the box 5 when the vertical section 644 is collided by accidents. In the preferred embodiment of this invention, a blocking panel 63 is disposed at the position between the bumpers 61 where the bumpers 61 are coupled to the groove 66. The blocking panel 63 has a sign or a textual description to indicating the moving direction, so that after the latching member 64 is installed into the groove 66, the blocking panel 63 limits and prevents the latching member 64 from falling out from the groove 66.
In addition, since the groove 66 and the horizontal section 642 have corresponding sizes, so that the horizontal section 642 can move in the groove 66, and pass through or leave the hole 520. However, the horizontal section 642 has a protruded pillar 646, such that the sum of the width of the horizontal section 642 and the size of the two protruded pillars 646 will be larger than the width of the groove 66. Therefore, it is uneasy to install the horizontal section 642 into the groove 66. To facilitate the installation of the horizontal section 642 into the groove 66, this embodiment comprises a rectangular hole 68 on the horizontal section 642 at the position proximate the protruded pillar 646, so that when the horizontal section 642 is installed into the groove 66, the protruded pillars 646 are pressed against the sidewall of the groove 66. By means of the space provided by the rectangular hole 68, the protruded pillars 646 are moved towards the rectangular hole 68 such that the horizontal section 642 is deformed to allow the horizontal section 642 and the protruded pillars 646 to be installed into the groove 66 and the sliding track 602 respectively.
Further, a track bar 67 is disposed on both sides of the sliding frame 6 adjacent to the end surface 60, and a track (not shown in the figure) having a shape and size corresponding to the track bar 67 is disposed on both sides corresponding to the opening 50 inside the box 5. After the sliding frame 6 has been pushed to a distance into the box 5, the track and track bar 67 will be engaged, which will make the process of pushing the sliding frame 6 into the box 5 easier and smoother.
By means of the foregoing components, the computer casing makes use of the latching member 64 and the connecting section 52 for the connection, so that the sliding frame 6 and the box 5 can be installed or uninstalled conveniently. The present invention can effectively overcome the shortcomings of the traditional computer casing that uses screws to connect the lid and the casing.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
