ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to an automatic suspender reeling device, and especially to such a device in which an engaging member and a ratchet wheel are mutually engaged with or separated from each other to control pulling out or retracting of a wound suspender, such that adjustment of the length of extension of the suspender is obtained. A backpack or a handbag is provided on both lateral sides thereof with such a reeling device, and by operation of the free winding of the reeling device for adjustment in order to get a suitable length of the suspender, the suspender can be extended for shouldering, or shortened for hand carrying, and the backpack or the handbag can thus be carried easily.
2. Description of the Prior Art
Various carrying tools such as bags, packs etc. sold in the markets are provided with suspenders for shouldering by users; in use, the suspenders have to be adjusted to get suitable lengths to attain desired factors that involve sizes of the users or the bags or packs to suit shouldering by the users in a convenient way. Suspenders used on various bags or packs are all controlled by engagement of buckles each in the shape of “{circumflex over (−)}”, such a “{circumflex over (−)}” shaped buckle “A” (as shown in
FIGS. 1 and 1A
) has a middle rod “B” is connected with one end of a suspender
10
, the other end of the suspender
10
is extended through a ring “C” of a bag, and then through the “{circumflex over (−)}” shaped buckle “A”. The aforesaid other end of the suspender
10
is fixedly connected to another ring “C”. In this arrangement, when the length of the suspender
10
is adjusted, the parts of the suspender
10
on the left and the right sides of the “{circumflex over (−)}” shaped buckle “A” must be pulled to displace the “{circumflex over (−)}” shaped buckle “A” on the suspender
10
, and the length of the suspender
10
can be adjusted. Such mode of adjustment is difficult and some problems are listed as follows:
1. The “{circumflex over (−)}” shaped buckle “A” is directly provided on the suspender
10
, and by pulling of the suspender
10
, the “{circumflex over (−)}” shaped buckle “A” is tightly sustained on the suspender
10
, such that displacement or adjustment of the “{circumflex over (−)}” shaped buckle “A” is quite difficult.
2. When the suspender
10
is extended through the “{circumflex over (−)}” shaped buckle “A”, it is often torn by the hooking of the “{circumflex over (−)}”shaped buckle “A”, such that, the area to be adjusted always causes the tearing off of threads, and breakage of the suspender
10
may occur. And when the suspender
10
is not used temporarily, it can not be withdrawn for storage, but can only be randomly placed on the bag, hence the suspender
10
may become attached to some external item or be tangled on one's body, accidents may occur.
The above stated problems created in using the prior art suspender makes bags inconvenient for carrying, and improvement is warranted.
SUMMARY OF THE INVENTION
The main object of the present invention is to establish the structure of the automatic reeling device by extending a suspender through an engaging member and then fixing it on a ratchet wheel, and by mounting the engaging member and the ratchet wheel together in a box. The reeling device can now be installed on any bag to adjust the length of extension of the suspender quickly and conveniently.
The secondary object of the present invention is to provide an engaging portion on the bottom of the engaging member in the reeling device for engaging with the teeth of the ratchet wheel. By engaging the engaging member with the ratchet wheel, the suspender can extend through the engaging member to be pulled out or retracted.
Another object of the present invention is to make the engaging member of the reeling device movable upwardly to render the engaging portion on the bottom of the engaging member to move away from the teeth of the ratchet wheel so that a helix spring in the ratchet wheel winds back to reel the suspender back onto the ratchet wheel.
A further object of the present invention is to provide a recess on the engaging member, and to provide a protrusion on the reeling device corresponding to the recess. By engaging the protrusion in the recess, the effect of fixing the engaging member on the reeling device can be enhanced, and the engaging member is not subjected to being swayed or displaced.
The present invention will be apparent after reading the detailed description of the preferred embodiments in reference to the accompanying drawings.
