Referring to FIG. 1, an exemplary embodiment of a collapsible device includes a base 10, a connecting member 20 pivotally mounted to the base 10, two hinges 30, two resilient members 40, two slide units 50, a plurality of fasteners 60, and a cover 70. In this embodiment, the fasteners 60 are screws.
The base 10 defines a depressed portion 12 in a rear side of a top of the base 10, two receiving grooves 14 in opposite ends of the depressed portion 12, and a connecting groove 16 in a front side of the depressed portion 12. The connecting groove 16 is connected between and communicates with the two receiving grooves 14. The depressed portion 12 defines two fixing notches 122 in opposite ends of the depressed portion 12. Each fixing notch 122 communicates with a corresponding receiving groove 14. Obviously, an operating element (not shown), such as a keyboard, and/or operating control can be positioned on a front side of the top of the base 10.
The connecting member 20 is longitudinally planar. Two fixing protrusions 26 each defining a matching hole 262 protrude from opposite ends of a front side of the connecting member 20. A plurality of fixing holes 22 are defined in the opposite ends of the connecting member 20. Two mounting holes 24 are defined in the front side of the connecting member 20, between the fixing protrusions 26.
Each hinge 30 includes a first connecting portion 32, and a second connecting portion 34 rotatable relative to the first connecting portion 32.
Referring to FIGS. 2 and 4, each resilient member 40 includes a holding portion 42, two pairs of springs 44 received in the holding portion 41, and two fitting portions 46 slidably mounted to opposite ends of the holding portion 42, correspondingly.
The holding portion 42 includes a top plate 420 and two generally U-shaped flanges 423 extending down from opposite sides of the top plate 420, respectively. Two slide grooves 422 are bounded by the flanges 423, respectively, and located under the top plate 420. The slide grooves 422 are spaced from each other. The top plate 420 defines two clamping slots 424 aligned with each other, between the slide grooves 422.
Each fitting portion 46 defines a fastening hole 460 in a first end of the fitting portion 46. A first received post 464 and two second received posts 462 at opposite sides of the first received post 464 extend from a second end of the fitting portion 46, opposite to the first end of the fitting portion 46. The first received post 464 and the second received posts 462 are separated, so that two cutouts 463 are formed at opposite sides of each second received post 462 o receive ends of the corresponding pair of springs 44. Two clamping channels 467 are defined in a bottom of each fitting portion 46, extending through the first and second ends of the fitting portion 46. Distal sides of the flanges 423 of the holding portion 42 slidably engage in the clamping channels 467, respectively. A U-shaped through groove 468 is defined in each fitting portion 46, between the clamping channels 467. An elastic tongue 47 is formed in the through groove 468. A hook 470 protrudes from a distal end of a top of the tongue 47.
During assembly of each resilient member 40, each pair of springs 44 is received in a corresponding slide groove 422 of the holding portion 42. The fitting portions 46 are mounted to opposite ends of the holding portion 42, with the first received posts 464 of the fitting portions 46 located between the flanges 423 of the holding portion 42, and the second received posts 462 of the fitting portions 46 received in the slide grooves 422, correspondingly. Therefore, opposite ends of each pair of springs 44 are received in the cutouts 463 of the fitting portions 46, correspondingly. The hooks 470 of the fitting portions 46 are slidably engaged in the clamping slots 424 of the holding portion 42, respectively. When the fitting portions 46 are moved towards each other and deform the springs 44, along the distal sides of the flanges 423, the hooks 470 are slid in the clamping slots 424, and can be hooked with edges bounding the clamping slots 424, correspondingly.
Referring to FIGS. 3 and 4, each slide unit 50 includes a locking member 52, a fixing member 54, and a receiving member 56 defining two fixing holes 560. The locking member 52 includes four sidewalls (not labeled) perpendicularly extending down from sides of the locking member 52. A plurality of elastic locking tabs 522 extend from the sidewalls. A protrusion 524 extends from each locking tab 522. The fixing member 54 defines a receiving groove 542 in a top of the fixing member 54, to slidably receive the receiving member 56. A bottom of the receiving groove 542 defines a slide slot 544 extending through a bottom of the fixing member 54, with the fixing holes 560 aligned with the slide slot 544. A plurality of fixing blocks 546 perpendicularly extend out of the receiving groove 542 from opposite sidewalls bounding the receiving groove 542, and each fixing block 546 defines a fixing hole 547. The bottom of the receiving groove 542 defines a plurality of clamping slots 545, besides the slide slot 544 and adjacent to the sidewalls bounding the receiving groove 542, correspondingly.
In another embodiment, the locking member 52 and the clamping slots 545 can be omitted.
The cover 70 defines two mounting grooves 72 in opposite ends of a bottom of the cover 70, correspondingly. The shape of each groove 72 corresponds to the fixing member 54 of a corresponding slide unit 50. Two fixing holes 74 are defined in the cover 70, adjacent to the mounting grooves 72 correspondingly. Obviously, a display screen (not shown) may be mounted to a top of the cover 70, opposite to the mounting grooves 72.
Referring to FIG. 5, in assembling the collapsible device, the second connecting portions 34 of the hinges 30 are fixed to the receiving grooves 14 of the base 10 via screws (not shown), correspondingly. The first connecting portions 34 of the hinges 30 are fixedly engaged in the matching holes 262 of the connecting member 20, correspondingly. Therefore, the connecting members 20 are hinged to the base 10 via the hinges 30. The fixing protrusions 26 of the connecting member 20 are accommodated in the fixing notches 122 of the base 10, correspondingly.
The plurality of fasteners 60 are passed through the plurality of fixing holes 22 of the connecting member 20 and the slide slots 544 of the slide units 50 in that order, and then screwed into the fixing holes 560 of the receiving members 56 slidably received in the receiving grooves 542 of the fixing members 54, correspondingly. The locking members 52 cover the receiving grooves 542 of the fixing members 54, with the protrusions 524 of the locking tabs 522 of the locking members 52 locked in the clamping slots 545 of the fixing members 54, correspondingly. The fixing members 54 are engaged in the mounting grooves 72 of the cover 70, and then a plurality of screws (not shown) are passed through the fixing holes 547 of the fixing members 54 to engage with the cover 70, correspondingly. Therefore, the fixing members 54 are fixed to the cover 70, with the locking members 52 resisting against the cover 70. A screw (not shown) is passed through the fastening hole 460 of one of the fitting portions 46 of each resilient member 40, and then screwed into a corresponding fixing hole 74 of the cover 70, correspondingly. Similarly, a screw (not shown) is passed through the fastening hole 460 of the other fitting portion 46 of each resilient member 40, and then screwed into a corresponding mounting hole 24 of the connecting member 20, correspondingly. Therefore, the resilient members 40 are fixed between the cover 70 and the connecting member 20, and cannot cross with each other. After fully assembly, the connecting member 20 is rotatably received in the depressed portion 12 of the base 10.
Referring to FIGS. 6 to 8, in use, when the cover 70 is slid rearward on the base 10 from a first position shown in FIG. 5 to a second position shown in FIG. 6, together with the fixing members 54, one of the fitting portions 46 of each resilient member 40 is moved with the cover 70 to deform the springs 44 of the corresponding resilient member 40. In this process, the receiving members 56 of the slide units 50 are slid relative to the fixing members 54 in the corresponding receiving grooves 542 of the fixing members 54 of the slide units 50. The cover 70 needs much more force to slide because of the elasticity of the springs 44. As a result, the cover 70 cannot be started to open unless enough force is used. Correspondingly, the cover 70 needs much more force to start to close because of the elasticity of the springs 44. When the resilient members 40 are aligned in a line, the springs 44 fully distort. The cover 70 is further slid rearward to a third position shown in FIG. 7, together with the springs 44 returning to normal, such that the elasticity of the springs 44 force the cover 70 to slide lightly. When the receiving members 56 resist against ends of the receiving grooves 542, the cover 70 cannot slide further. At this time, the operating element set at the base 10 is exposed, and then, the collapsible device can be operated via the operating element.
In addition, when the cover 70 cannot slide further, the front side of the cover 70 is aligned with the connecting groove 16 of the base 10. The cover 70 is rotated about the hinges 30 relative to the base 10, together with the connecting member 20, to provide another position for operating the collapsible device. In this process, the first connecting portions 32 of the hinges 30 are rotated relative to the second connecting portion 32, so that, the cover 70 may remain at any angle with respect to the base 10 via the hinges 30.
It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of its material advantages, the example hereinbefore described merely being exemplary embodiment.
