DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to FIGS. 1-4, a cup holder in accordance with the preferred embodiment of the present invention comprises a fixed seat 1, a movable clamping bar 2 mounted on the fixed seat 1, and a support rack 3 mounted on the fixed seat 1.
The fixed seat 1 includes a base 11, a slide 13, a locking block 14, a pull rod 15, a threaded rod 16 and a rotation member 17. The base 11 has an end provided with a fixed clamping plate 18. The fixed clamping plate 18 of the base 11 has a side face provided with a fixed pad 181. The base 11 has two sides each provided with a positioning member 12 which has a protruding retaining end 121. The base 11 has an interior provided with a space 111 which has a bottom provided with a slideway 112. The slide 13 is slidably mounted on the slideway 112 and has a top provided with a recessed chamber 131. The locking block 14 is mounted in the chamber 131 of the slide 13. An elastic member 132 is biased between the locking block 14 and the chamber 131 of the slide 13 to push the locking block 14 upward. The locking block 14 has a top provided with a plurality of first locking teeth 141. The locking block 14 is provided with a longitudinal slot 142 and a transverse slot 143. The transverse slot 143 is located at a bottom of and connected to the longitudinal slot 142. Thus, the longitudinal slot 142 and the transverse slot 143 of the locking block 14 form a substantially L-shaped hole. The locking block 14 is transversely provided with a through hole 144. The pull rod 15 extends through and is movable in the through hole 144. A positioning piece 151 is transversely mounted on the pull rod 15 and is movable between the longitudinal slot 142 and the transverse slot 143. The threaded rod 16 is connected with a distal end of the pull rod 15. The rotation member 17 is pivotally mounted on the base 11 and has a screw member 171 screwed onto the threaded rod 16.
The movable clamping bar 2 includes a shank 21 having a first end inserted into a top of the space 111 of the base 11, and a movable clamping plate 22 extending downward from a second end of the shank 21 and facing the fixed clamping plate 18. The shank 21 has a bottom provided with a plurality of second locking teeth 211 meshing with the first locking teeth 141 of the locking block 14. The movable clamping plate 22 of the movable clamping bar 2 has a side face provided with a movable pad 221 facing the fixed clamping plate 18.
The support rack 3 includes a bracket 31 and a utensil 34 mounted on the bracket 31. The bracket 31 is provided with at least one receiving recess 32 and at least one opening 33 for placing bottles, cups, bowls and the like. The bracket 31 has a mediate section having two sides each provided with a press button 35 which has a protruding tenon 351 locked onto the retaining end 121 of the respective positioning member 12 of the base 11. Preferably, the bracket 31 is provided with a plurality of receiving recesses 32 and a plurality of openings 33, and the receiving recesses 32 and the openings 33 of the bracket 31 are arranged in an alternating manner. The utensil 34 is combined with a bottom of the at least one opening 33 of the bracket 31 by a plurality of screws so that the utensil 34 can be removed freely from the bracket 31.
In operation, referring to FIGS. 5 and 6 with reference to FIGS. 1-4, the shank 21 of the movable clamping bar 2 is moved outward from the space 111 of the base 11 to allow entrance of a rail 4 of a baby stroller between the movable clamping plate 22 and the fixed clamping plate 18 as shown in FIG. 5. Then, the shank 21 of the movable clamping bar 2 is pushed toward the base 11 to move the movable clamping plate 22 to touch the rail 4 so that the rail 4 is clamped between the movable clamping plate 22 and the fixed clamping plate 18 as shown in FIG. 6. When the shank 21 of the movable clamping bar 2 is pushed toward the base 11, the second locking teeth 211 of the shank 21 successively push the first locking teeth 141 of the locking block 14 as shown in FIG. 5 so that the locking block 14 is pushed downward successively, while the elastic member 132 pushes the locking block 14 upward successively, so that the first locking teeth 141 of the locking block 14 again mesh with the second locking teeth 211 of the shank 21 as shown in FIG. 6 so as to restrict the shank 21. When the locking block 14 is pushed downward by the shank 21 and is pushed upward by the elastic member 132, the positioning piece 151 slides in the longitudinal slot 142, without obstructing movement of the locking block 14. When the rotation member 17 is rotated, the screw member 171 is screwed on and rotated relative to the threaded rod 16 so that the threaded rod 16 is moved toward the rotation member 17, and the pull rod 15 is driven by the threaded rod 16 and is moved backward, such that the positioning piece 151 on the pull rod 15 slides into the transverse slot 143 of the locking block 14 as shown in FIG. 6. Thus, the locking block 14 is locked by the positioning piece 151, so that the first locking teeth 141 of the locking block 14 engage the second locking teeth 211 of the shank 21 so as to lock the shank 21 by the locking block 14. When the rotation member 17 is rotated successively, the pull rod 15 drives the slide 13 to move backward in the space 111 along the slideway 112 to move the locking block 14 backward which moves the shank 21 backward to slightly shorten the distance between the movable clamping plate 22 and the fixed clamping plate 18 to achieve a micro-adjustment tightening effect, so that the rail 4 is clamped exactly and solidly between the movable clamping plate 22 and the fixed clamping plate 18.
In detachment, referring to FIGS. 7 and 8 with reference to FIGS. 1-4, when the press button 35 at each of the two sides of the bracket 31 is pressed inward, the protruding tenon 351 of the press button 35 of the bracket 31 is detached from the retaining end 121 of the respective positioning member 12 of the base 11, so that the bracket 31 is unlocked and can be removed from the base 11.
Accordingly, the shank 21 of the movable clamping bar 2 is pushed to sandwich the rail 4 of the baby stroller between the movable clamping plate 22 and the fixed clamping plate 18, and the rotation member 17 is rotated to drive the positioning piece 151 to lock the locking block 14, so that the rail 4 is clamped between the movable clamping plate 22 and the fixed clamping plate 18. In addition, the user only needs to push the movable clamping bar 2 and rotate the rotation member 17 so as to lock the cup holder onto the rail 4 of the baby stroller so that the cup holder is attached to the baby stroller easily, quickly and conveniently. Further, the cup holder is mounted on and detached from the baby stroller freely.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
