Patent Application
20100038041
The present application is related to a suspension pulley on a partition door, and more particularly to a pulley structure which can guide the door plank from a single track to a dual track so as to gather plural door planks together.
Usually, many markets or restaurants need to use movable partitions for forming temporary wall(s) so as to separate one space into two or to confine an isolated room. As to the ceiling, it has to equip with tracks for hanging partitions, and further, pulley also has to be mounted between the track and the partitions for folding and unfolding the partitions. Since partitions are usually made of wood, glass or fireproof board, after folding up, all the partitions must have to occupy a certain width. Generally, the track is formed to be straight, so that the partitions only can be pushed aside for being folded up. But, because different places have different layouts, the partitions always have to be gathered to a predetermined place for preventing from obstructing the view, and further, the track at the predetermined place must be bent and then forms a dual track, so that the partitions can be guided to turn toward one side and then go into the dual track for being gathered together. Since the partitions are quite heavy, it is better that the rolling wheels on the track can provide a stable and smooth rolling without jumping, especially at the turning point, so that the rolling wheels can smoothly guide the partitions to turn toward one side and enter the dual track for gathering together.
The object of the present application is to provide a suspension pulley structure for movable partitions which can be applied to all kinds of tracks for gathering door planks, wherein two guiding wheels are mounted on the bottom at the front end and the rear end for smoothing the moving along the track and the turning slide rail, and guiding wheels are mounted on the top guiding plate at the left and the right sides for rejecting against the inner walls of the track and the slide rail so as to position the wheel seat and provide stability, especially at the turning point.
For achieving the object described above, the present application provides a suspension pulley structure for movable partitions mounted on a track on the ceiling including a wheel seat sleeved in the track and penetrated through a pendent axis, which is locked with a door plank. The wheel seat has two guiding wheels mounted on the bottom at the front and the rear ends thereof for moving along the track, the right and the left sides of the wheel seat both have a pair of rolling wheels pivotally mounted thereon for rolling on the inner bottom wall of the track, and the rolling wheels are pivoted with the spindles of the wheel seat through a bearing. Moreover, the pendent axis has a hanger shaft head at the top thereof, the hanger shaft head is accommodated in an indentation port of the wheel seat, the pendent axis is further sleeved by a thrust bearing for smoothly turning the wheel seat, and the top of the wheel seat is locked with a guiding plate for limiting the upward rejection of the pendent axis. Furthermore, the top surface of the guiding plate has one side higher than the opposite side with each side has a pair of guiding wheels pivoted thereon. Besides, the track has a slide rail mounted at the turning point, the slide rail has a division protruded on the inner top wall thereof for isolating a guiding slot through cooperating with one inner side wall of the slide rail, and the guiding slot can guide the two guiding wheels protruded on one side of the guiding plate to enter, thereby guiding the wheel seat to turn and enter the track for gathering the door planks.
The foregoing aspects and many of the attendant advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
Please refer to
A block wheel seat 20, sleeved in the slide rail 10 and having an indentation port 21, wherein as shown in
A pendent axis 30, which is downwardly extended from the indentation port 21 at the top of the wheel seat 20 and penetrates through the rail slot al of the track a and the rail slot 11 of the slide rail 10, wherein the pendent axis 30 has a hanger shaft head 31 at the top thereof, the hanger shaft head 31 is accommodated in the indentation port 21 for internally sleeving to a thrust bearing 33, the pendent axis 30 penetrates through the center of the thrust bearing 33, the guiding plate 24 covers the top of the wheel seat 20 for sealing the indentation port 21 and is locked with the wheel seat through two bolts 25 at the front end and the rear end, and the pendent axis 30 has a thread section 34 at the lower end thereof.
Wherein the top surface of the guiding plate 24 has one side higher than the opposite side and the two sides respectively have two guiding wheels 241 pivotally mounted thereon.
Thereby, the thread sections 34 respectively on two pendent axes 30 under two wheel seats 20 can lock with the top of a door plank 40, the guiding wheels 22 of the two wheel seats 20 can move along the rail slot al of the track a, as shown in
Moreover, in the present application, the two guiding wheels 241 on the higher portion of the top of the guiding plate 24 can be assembled with the T-shaped slide rail 10a, as shown in
If the user wants to alter the gathering direction of the door planks 40 as the left side, as shown in
Please refer to
Since in the present application, two wheel seats 20 which are pivoted to one single door plank 40 can be turned freely and respectively, so that the door plank 40 can be moved along different types of track a, and thus, the two wheel seats 20 on the top of the door plank 40 can be guided into all kinds of liner tracks and then guided into the dual track, so as to gather together. In addition, the slide rail 10 can have an L shape of 90° to combine with a T-shaped slide rail 10a, so as to be used in the outlay as shown in
In the aforesaid, the present application is advantageous that:
1. The spindles at the right and the left sides of the wheel seat 20 are sleeved with bearings, which are respectively connected with the rolling wheel 23, and the respective two rolling wheels 23 at the left and the right sides can mount on two portions of the inner bottom wall of the track a, so that the wheel seat 20 can have an easy moving, and further, the wheel seat 20 also has two guiding wheels 22 at the front and the rear ends and four guiding wheels 241 on the top for rejecting against the inner portion of the track a, so as to stabilize the rolling and prevent from swaying.
2. A thrust bearing 33 is mounted between the wheel seat 20 and the pendent axis 30, so that the wheel seat 20 can have a nimble move along the slide rail 10, thereby facilitating the folding and unfolding of the door planks 40. Furthermore, the guiding plate 24 and the wheel seat 20 are locked together for providing sufficient intensity, so that it can avoid the pendent axis 30 and the door planks 40 from being pushed upward and also provide the anti-theft capability.
3. The two sides of the guiding plate 24 on the top of the wheel seat 20 have different heights, so that the two guiding wheels 241 on the higher top can turn along the guiding slot 13 inside the slide rail 10a, thereby it can be applied to T-shaped slide rail 10a for providing smooth rolling and moving.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
