BACKGROUND OF THE PRESENT INVENTION

Field of Invention

The present invention relates to a shoe cover dispenser apparatus, and more particularly to a dispenser apparatus for detachable shoe covers and a method of dispensing detachable shoe cover by the dispenser apparatus, wherein the dispenser apparatus and the shoe covers being stored and dispensed by the dispenser apparatus are configured to allow each of the shoe covers being easily and conveniently detached from the dispenser apparatus without detorting and causing damage to the shoe cover in a safe and reliable manner.

Description of Related Arts

With the development of science and technology, the manufacturing of some products must be completed in a dust-free workshop. Therefore, people must wear dust-free clothing and clean disposable shoe covers before entering the dust-free workshop to avoid any pollution to the dust-free workshop. Besides, shoe cover assembly and shoe cover dispenser apparatus are widely used in furniture, factories, model houses, hospitals, dust-free workshops and other places that require environmental cleanliness.

Traditional shoe cover dispensers are complicated and difficult in operation. During the wearing of some shoe covers, user is required to manually pull the shoe covers out which is inconvenient for wearing the shoe covers. U.S. patent numbers U.S. Pat. Nos. 9,764,889, 9,771,207, 9,834,368, and U.S. Ser. No. 11/478,098, invented by the inventor of the present invention, disclose shoe cover dispenser devices which are convenient for people to wear the shoe covers, facilitate the integration storage of multiple pairs of shoe covers and automatically open the shoe cover in turn for wearing.

In order to allow the perforations of each shoe cover passing from the upper portions to the end portions of the installation arms of the dispenser machine, the first end portions of the installation arms are respectively locked by the first locking member and then the second end portions of the installation arms can be free end portions and are released from the second locking member and removed from the second end portions, so that the plurality of shoe covers can be ready for dispensing from the second end portions of the installation arms. Nevertheless, the first and second locking members of the locking assembly have to be configured as simple as possible in a reliable manner and the installation of the first and second locking members by the user must be precise and rigid to ensure smooth dispensing operation. Accordingly, it will be a desired innovative improvement to configure the dispenser machine to be capable of smoothly dispensing shoe covers without the relatively complicated locking and releasing operation of the locking assembly.

The dispenser machines as disclosed in the above related patents require each row of two front perforation portions of a rear shoe cover passes through a row of two rear joint perforations of an adjacent front shoe cover to expose the row of two front joint perforations that allows each of the connecting rods to pass through the front joint perforations, so that a plurality of the shoe covers are connected and joined by the two connecting rods in series. It is a good arrangement since the installation of the shoe covers on the two connecting rods only requires the two connecting rods to pass through the row of the rear joint perforations. However, during the shoe cover is being pulled out by a pulling force, the interconnecting of the shoe covers with respect to the locking assembly may become holding on the installation arms tighter and tighter and produce resistance for the shoe covers to move along the installation arms. Therefore, occasionally, when one shoe cover is not run smoothly on the installation arms without any resistance to be removed from the installation arms, or even being pulled to be broken, the user has to halt the dispenser machine to remove the stuck or broken shoe cover and reset the dispenser machine to function.
