Adjusting device

Referring now to the figures of the drawings in detail, and first, particularly to FIG. 3A, it shows a three-dimensional decomposition drawing of the adjusting device 302 , which is equipped in the illustrated exemplary embodiment with a foot member 304 , a rubber pad 306 , a supporting member 308 , and a moving member 310 . The supporting member 308 is fixed to the foot member 304 , and the moving member 310 comprising at least a moving body 312 , a button 314 , a U-clip 316 , and a spring 318 . The rubber pad 306 is set in the base of the foot member 304 , so that a projector is coupled to the adjusting device 302 stably equipped on the projector plate, preventing the sliding of the projector on the plate.

The supporting member 308 is equipped with the racks 320 a and 320 b , which include tooth-ditched outlets 322 a and 322 b parallel in the opposite side of the supporting member 308 . In other words, the tooth-ditched outlets have the same trend, which are perpendicular to the vertical direction of the supporting member 308 . Each tooth-ditched outlet in 322 a and 322 b is arranged at the same distance from each other, as well as the same height relative to each other on the supporting member 308 . Furthermore, the other side of the supporting member 308 is equipped with slipping ditches 324 a and 324 b , and a protruding part 326 above the rack 320 a in the vicinity of the top of the supporting member 308 .

The moving body 312 is a box shape with the top 312 a opposite to the bottom 312 b , the side 312 c opposite to the side 312 d and the side 312 e opposite to the side 312 f . There is a passageway 328 a from the top 312 a to the bottom 312 b with slipping axles 329 a and 329 b on both opposite walls of the passageway 328 a . The passageway 328 a is sized to receive the supporting member 308 while the slipping axles 329 a and 329 b can embed in slipping ditches 324 a and 324 b , respectively. The moving body 312 will slide along the direction of the arrow 350 shown in FIG. 3A, backwards and forwards on the supporting member 308 . Moreover, the other passageway 328 b is through sides 312 c and 312 d of the moving body 312 , which is connected and perpendicular to the other passageway 328 a . Further still, the frame structure side 312 c is equipped with a fixed bolt 330 , which has two apertures 332 a and 332 b . On the other hand, the frame structure side 312 d is connected with a stretched object 334 including an orientation bolt 336 , a fillister 338 , and an aperture 340 , wherein the orientation bolt 336 is set in the fillister 338 and the fillister 338 is coupled to the passageway 328 b . The moving body 312 can be fixed under a projector by using a screw to lock through the aperture 340 . Furthermore, the sides 312 e and 312 f are equipped with receiving apertures 342 a and 342 b respectively, wherein the receiving apertures 342 a and 342 b are connected with apertures 332 a and 332 b.

The button 314 can be buckled to the side 312 c of the moving body 312 along the direction of the arrow 360 in FIG. 3A by imposing a force horizontally. Simultaneously, referring to the FIG. 3B, it shows the button including a button body 314 a , a propping board 314 b , and hooks 314 c and 314 d . The propping board 314 b is set on the internal side of the button body 314 a in the direction parallel to the arrow 360 , so that the propping board 314 b is installed on the inside of the button body 314 a in a manner perpendicular to the side 312 c . The propping board 314 b includes a narrow end and a wide end, wherein the wide end is coupled to the inward end of the button body 314 a while the narrow end is approaching to the side 312 c . Additionally, hooks 314 c and 314 d are equipped to the inside of the button body 314 a , so as to connect through apertures 332 a and 332 b and buckle with the receiving apertures 342 a and 342 b , so that the button 314 is coupled to the moving body 312 . Furthermore, the right end of the spring 318 is mounted to the fixed bolt 330 against the side 312 c , while the left end of the spring 318 is against the inside of the button body 314 a , so that the elasticity of the spring 318 enables the button 314 to maintain a certain distance with the moving body 312 .

The U-clip 316 is inlaid to the stretched object 334 of the moving body 312 along the direction of the arrow 370 in FIG. 3 A. The U-clip 316 includes a curved part 316 a and clip parts 316 b and 316 c , wherein the curved part 316 a is set inside the fillister 338 and buckled to the fixed bolt 336 , and the clip parts 316 b and 316 c are parallel and connected to both sides of the curved part 316 a , with coupling through the passageway 328 b . When the button 314 is buckled to the moving body 312 in the natural status, the narrow end of the propping board 314 b is positioned between the clip parts 316 b and 316 c . In addition, the clip parts 316 b and 316 c are wedged in the tooth-ditched outlets 322 a and 322 b of the racks 320 a and 320 b , respectively, so that the moving member 310 is fixed to the supporting member 308 .

Particularly, the thickness and shape of the clip parts 316 b and 316 c must match those of the tooth-ditched outlets 322 a and 322 b , and the distance between the clip parts 316 b and 316 c should be the same as the distance between the tooth-ditched outlets 322 a and 322 b . And also, the clip part 316 b parallels the clip part 316 c in the natural status, so that the narrow end of propping board 314 b is exactly located between clip parts 316 b and 316 c . As a result, the clip parts 316 b and 316 c are buckled to the racks 320 a and 320 b as shown in FIG. 3A, respectively. The detailed drawings of the propping board and both clip parts in FIG. 3A are shown in FIG. 4 A. Obviously, both ends of the clip parts 316 b and 316 c bend outward to prevent the attrition of the propping board 314 b , which may cause holding failure of the propping board 314 b . When the button body 314 a and the propping board 314 b are pushed, they move along the direction as shown by the arrow 450 in FIG. 4 A. And then the clip parts 316 b and 316 c move relatively toward the wide end of the propping board 314 b , and are held apart by the propping board 314 b for an angle θ. As a result, the clip parts 316 b and 316 c depart from the racks 320 a and 320 b and the moving member 310 can slide opposite to the supporting member 308 .

When the force on the button body 314 a is released, the button body 314 a and the propping board 314 b move along the direction of the arrow 460 due to the elasticity of the spring 318 , so that the propping board 314 b and the clip parts 316 b and 316 c move oppositely, as shown in FIG. 4 B. That is, the clip parts 316 b and 316 c move along from the wide end toward the narrow end and then return to the original parallel status. As shown in FIG. 4A, the clip parts 316 b and 316 c are buckled to the racks 320 a and 320 b , respectively.

Furthermore, in order to strengthen the buckling of the clip parts 316 b and 316 c to the racks 320 a and 320 b , a specific design of the shape and model of the tooth-ditched outlets 322 a and 322 b is applied, as shown in FIG. 5 . The tooth-ditched outlets 322 a and 322 b are well designed with outlets slanted upward to ensure a strong buckling effect of the clip parts 316 b and 316 c to the racks 320 a and 320 b.

Referring to FIG. 6, the components of an adjusting device are shown. As mentioned above, a user can push the button 314 along with the direction of the arrow 650 in FIG. 6, so that the propping board 314 b can hold open the clip parts 316 b and 316 c , and then the clip parts 316 b and 316 c move along from the narrow end to the wide end, enabling the clip parts 316 b and 316 c to disengage from the racks 320 a and 320 b , wherein the clip parts 316 b and 316 c form a propping angle θ as depicted in FIG. 4 B. Subsequently, the user can make the moving member 310 slide upward and downward along the direction of the arrow 660 in FIG. 6 to adjust the angle of elevation of a projector on the projector plate. Meanwhile the supporting member 308 can move in and out of a fillister under the projector, relatively. When the moving member 310 slides to the top of the supporting member 308 , a protruding part 326 will lock it so as to prevent it from disengaging.

Accordingly, as the user adjusts the moving member 310 to a required location and fixes the angle of elevation of a projector, the user can release the force from the button 314 so that the elasticity of a spring 318 makes the button 314 return to the origin location, and the propping board 314 b moves along with the button body 314 a to remove from the moving body 312 . Finally, the clip parts 316 b and 316 c will move along the propping board 314 b from the wide end to the narrow end, relatively, so that the clip parts 316 b and 316 c connect to the racks 320 a and 320 b , respectively. Therefore, the clip parts 316 b and 316 c recover to the original parallel status.

Consequently, the invention is very advantageous in that it reduces the force required of the user and saves time by pressing the button 314 horizontally to adjust the elevation of a projector on the projector plate, and also, the adjusting device 302 can be installed in any other electronic products and portable small size and weight electronic products required to adjust the elevation.

Referring to FIG. 7A, a perspective view of the adjusting device in an alternative preferred embodiment is shown. The differences between the two preferred embodiments of the adjusting devices 302 (shown of FIG. 3A) and 702 are the moving member 710 and the force direction on the button 714 . Other devices such as the foot member 304 , the supporting member 308 , and the rubber pad 306 of the adjusting device 702 are the same as those of the adjusting device 302 , and so the operation of the adjusting devices 702 and 302 is identical.

The moving member 712 includes a moving body 712 , a button 714 , a U-clip 716 and a spring 718 . The moving body 712 is a box shape with the top 712 a opposite to the bottom 712 b , the side 712 c opposite to sides 712 d and the side 712 e opposite to the side 712 f . There is a passageway 728 a from the top 712 a to the bottom 712 b with the slipping axles 729 a and 729 b on both opposite walls of the passageway 728 a . The passageway 728 a is sized to receive the supporting member 308 so that the slipping axles 729 a and 729 b can be embedded in the slipping ditches 324 a and 324 b , respectively. The moving member 712 will slide along the direction of the arrow 750 , as shown in FIG. 7A, backwards and forwards on the supporting member 308 .

Moreover, the passageways 728 b and 728 c go through the sides 712 c and 712 d , which are connected and perpendicular to the passageway 728 a . Further still, the frame structure side 712 d is equipped with a stretched object 734 including a fixed bolt 736 , a fillister 738 , and an aperture 740 , with the fixed bolt 736 located inside the fillister 738 . The fillister 738 is interlinked with passageways 728 b and 728 c , so that the moving body 712 can be fixed under a projector by using a screw to lock through the aperture 740 . On the other hand, the frame structure sides 712 e and 712 f are equipped with the hooks 752 a and 752 b , wherein both hooks are parallel and protruding outward of the side 712 c , so as to buckle to the button 714 .

Referring to FIG. 7B, the button 714 shown includes a button body 714 a , a propping board 714 b , an hollow bolt 714 c , and a buckling board 714 d . The user can operate the button 714 by pushing the button body 714 a along the direction of the arrow 760 in FIG. 7A to buckle to the side 712 c . The propping board 714 b is located inside the button 714 a , which is perpendicular to the direction of the arrow 760 and parallel to the side 712 c . The propping board 714 b is equipped with one wide end and one narrow end, with the wide end connected to the button 714 a . The hollow bolt 714 c is located between the propping board 714 b and the button 714 a , with a spring 718 against protruding objects 762 a , 762 b , and 762 c , which can be locked under a projector by a screw. The top of the spring 718 is against the projector so that the elasticity maintains a certain distance between the button 714 and the projector.

Furthermore, the buckling board 714 d is parallel to the propping board 714 b including the buckling apertures 754 a and 754 b , and the slipping ditches 756 a and 756 b . The propping board 714 b is located between the hollow bolt 714 c and the buckling board 714 d . The buckling apertures 754 a and 754 b are connected with the hooks 752 a and 752 b respectively, so as to couple the button 714 to the moving body 712 . The slipping ditches 756 a and 756 b are located on the buckling board 714 d along both sides of the propping board 714 b corresponding to the apertures of the passageways 728 b and 728 c on the side 712 c.

The U-clip 716 is inlaid to the stretched object 734 of the moving member 712 along the direction of the arrow 770 in FIG. 7 A. The U-clip 716 includes a curved part 716 a , and the clip parts 716 b and 716 c , wherein the curved part 716 a is set inside the fillister 738 and is buckled to the fixed bolt 736 , and the clip parts 716 b and 716 c are parallel and connected to both sides of the curved part 716 a , with coupling through the passageways 728 b and 728 c . When the button 714 is buckled to the moving member 712 in the natural status, the clip parts 716 b and 716 c move through the slipping ditches 756 a and 756 b respectively so that the ends of the clip parts 716 b and 716 c are located in both sides of the propping board 714 b . In addition, the clip parts 716 b and 716 c are wedged in the tooth-ditched outlets 322 a and 322 b of the racks 320 a and 320 b , respectively, so that the moving member 702 is fixed to the supporting member 308 .

Particularly, the thickness and shape of the clip parts 716 b and 716 c must match the tooth-ditched outlets 322 a and 322 b respectively, and the distance between the clip parts 716 b and 716 c should be the same as the distance between the tooth-ditched outlets 322 a and 322 b , and also, the same as the above line X of the propping board 714 b . As a result, the clip parts 716 b and 716 c are coupled to the racks 320 a and 320 b , and the hooks 752 a and 752 b are coupled to the buckling apertures 754 a and 754 b , respectively, as shown in FIG. 8 A. When the user imposes a force on the button body 714 a vertically and the propping board 714 b , both move along the direction of the arrow 850 in FIG. 8A, and then the clip parts 716 b and 716 c move oppositely from the narrow end toward the wide end of the propping board 714 b . Meanwhile, the hooks 752 a and 752 b move from the top of the buckling apertures 754 a and 754 b toward the bottom, so that the propping board 714 b wilt hold the clip parts 716 b and 716 c to depart from the racks 320 a and 320 b , respectively, as shown in FIG. 8 B. When the user removes the force from the button body 714 a , the button body 714 a and the propping board 714 b move along the direction of the arrow 860 due to the elasticity of the spring 718 , 50 that the clip parts 716 b and 716 c move oppositely from the wide end toward the narrow end of the propping board 714 b and recover to original status, along with the hooks 752 a and 752 b moving from the bottom of the buckling apertures 754 a and 754 b toward the top, referring to FIG. 8 B. Thus, the clip parts 716 b and 716 c is connected with the racks 320 a and 320 b and then return to the original parallel status. Furthermore, in order to strengthen the buckling between the clip parts 716 b and 716 c with the racks 320 a and 320 b shown in FIG. 7A, the invention incorporates a specific design of the shape and model of the tooth-ditched outlets 322 a and 322 b , as shown in FIG. 5 . As mentioned above, the design ensures the strong buckling effect of the clip parts 716 b and 716 c to the racks 320 a and 320 b.

Referring to FIG. 9, the construction of the perspective view of an alternative adjusting device is shown. The user can use two screws to lock through the aperture 740 and the hollow bolt 714 c under a projector to fix the moving member 710 and the button 714 under the projector, so that the adjusting device 702 is fixed to the projector. When adjusting the elevation of the projector on the plate, firstly the button body 714 a together with the button 714 is pushed along with the direction of the arrow 950 in FIG. 9, so that the propping board 714 b moves upward with the button body 714 . Next, the propping board 714 b can hold apart the clip parts 716 b and 716 c , enabling the clip parts 716 b and 716 c to disengage from the racks 320 a and 320 b . Subsequently, the user can make the moving member 710 slide upward and downward along the direction of the arrow 960 in FIG. 9 to adjust the angle of elevation of a projector on the plate, and the supporting member 308 can move in and out of a fillister under the projector, relatively. When the moving member 710 slides to the top of the supporting member 308 , the protruding part 326 will lock it so as to prevent it from disengaging.

Accordingly, as the user adjusts the moving member 710 to the desired location and fixes the angle of elevation of a projector, the user can release the force from the button 714 so that the elasticity of the spring 718 makes the button 714 return to the original location, and the propping board 714 b moves downward with the button body 714 a . Ultimately, the clip parts 716 b and 716 c will recover to original distance, so that the clip parts 716 b and 716 c catch onto the tooth-ditched outlets 320 a and 320 b , respectively. Therefore, the moving member 710 is fixed to the supporting member 308 and the clip parts 316 b and 316 c recover to the original parallel status.

Consequently, the invention is very advantageous in that it reduces the time and effort required of the user, by allowing the user to press the button 714 to adjust the elevation of a projector on the plate. Additionally, the adjusting device 702 can be applied in other electronic products and even in portable, compact electronic products that also require elevation adjustments.

While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
