A shoe cover application device having a holding member for holding a shoe cover open in a receiving position to accommodate the insertion of a user shoe. The shoe cover application device also includes a separation member that separates the shoe cover from the holding member allowing the shoe cover to constrict around the user's shoe inserted into the shoe cover while the shoe cover was in the receiving position. Shoe covers of various materials, shapes and sizes may be used with the shoe cover application device of the present invention.
Description
BACKGROUND OF THE INVENTION
Protective disposable garments such as gowns, drapes, caps and shoe covers have been used for many years to minimize contamination in “cleanrooms” such as laboratories and medical operating rooms. Disposable shoe covers, in particular, are of great importance in these environments, as shoes are in constant contact with the “clean” area. In settings such as these, the shoe covers serve to protect the sterile atmosphere from dust and any other contaminates human traffic may introduce.
Shoe covers also serve to protect the wearer from hazards already present in these environments. The shoe covers prevent the wearer from being exposed to hazards such as electricity, chemicals, metals, microbiological agents, disease and tools. It is thus desirable to design a disposable shoe cover that prevents the transmission of contaminates to and from a shoe.
The use of disposable shoe covers is not limited to the aforementioned environments. Each environment requires a shoe cover made of a material having specific characteristics. As a result, disposable shoe covers may need to be fabricated from a wide array of materials including polyethylene or polypropylene sheet materials, non-woven fabrics or other disposable materials. It is therefore also desirable to design a disposable shoe cover that can be manufactured out of varied materials. Furthermore, the assortment of shoe shapes and sizes necessitate disposable shoe covers of various shapes and sizes.
Finally, it is necessary to design a disposable shoe cover that can be applied onto the wearer's shoe without the handling of the disposable shoe cover itself. If not, the purpose of maintaining a sterile preparation routine before entering to the clean room area may be defeated. Manual handling of the shoe covers may spoil the sanitary nature of the shoe covers. Most disposable shoe covers available today require manual application.
Nonetheless, attempts to address this concern have been made. An example of an automated shoe cover application device is disclosed in U.S. Pat. No. 3,694,939 which discloses an operation wherein the wearer's shoe is wrapped in heat-shrinkable material upon the insertion of the wearer's foot into a shrink-wrap device. While this type of device may do away with the need to manually handle the shoe cover during is application upon a shoe, it is not adaptable to be used with a wide range of disposable shoe covers made of the varying materials needed for various types of sanitary environments.
Additionally, such a device is expensive, complicated and could be dangerous. A heat-shrinking operation, such as the one disclosed in the aforementioned patent, requires multiple motors, a heating unit, heating elements, a blower and extensive wiring and electrical controllers. These elements are not only expensive but also form an intricate system that is difficult to maintain and repair. Furthermore, such an extensive electrical heating system increases the risk of injury to the user who must set his or her foot into the device to have it shrink-wrapped.
As described above, many approaches for applying shoe covers to a wearer's shoe have been proposes. Yet, there remains a need for a simple, inexpensive and safe means for applying shoe covers to a wearer's shoe without the handling of the shoe cover itself. Further, there is a need for an automatic shoe cover applicator compatible with shoe covers of varied materials, shapes and sizes.
SUMMARY OF THE INVENTION
Additional features and advantages of the invention will be set forth in the description which follow, an in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the apparatus particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the invention, as embodies and broadly described, the invention consists of shoe cover application device having a holding arrangement to hold a shoe cover open in a receiving position for the insertion of a user's shoe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIGS. 1-8
show the preferred embodiment of a shoe cover applicator device
100
. As shown specifically in
FIG. 1
, the shoe cover applicator device
100
has a body
10
, base
20
, and bin
30
. The bin
30
is configured to receive a package
200
of shoe covers. In one embodiment, the package
200
consists of continuous disposable shoe covers in a sealed package, as described in U.S. patent application Ser. No. 09/901,139, filed herewith. An example of the continuous type disposable shoe cover
310
is shown in FIG.
10
.
The continuous type disposable shoe cover
310
of the preferred embodiment as shown in
FIG. 10
will now be described in detail. As seen in the figure, multiple continuous type disposable shoe covers
310
are joined in a lineal
300
of shoe covers
310
. Each shoe cover
310
may be separated from the adjoining shoe covers
310
using perforated edges
380
. Each individual shoe cover
310
comprises a pair of side walls
320
, a heel portion
340
and a toe portion
350
. Together the side walls
320
, the heel portion
340
, and the toe portion
350
define an opening for receiving a shoe.
The shoe covers
310
include tubes
330
formed along the longitudinal edges of the shoe covers
310
. The tubes
330
are separated from the side walls
320
along cut lines
360
to form the heel portion
340
and toe portion
350
. The tubes
330
allow the shoe cover
310
to be conveyed through device
100
. The shoe covers
310
are also provided with at least one elastic member
370
disposed below the tubes
330
and between the heel portion
340
and toe portion
350
. The elastic member
370
permits the shoe cover
310
to contract around a shoe inserted into the shoe cover
310
and thereby substantially surround the shoe. It should be understood to one skilled in the art that multiple elastic member
370
or other means known in the art may be used to contract the shoe cover
310
about a shoe.
Generally, during operation, the shoe covers
310
are delivered from the package
200
, through the device
100
, to an application portion
80
. In the application portion
80
, the shoe cover
310
is positioned to accommodate entry of the user's foot. The user inserts his or her foot into the opened shoe cover
310
and then pulls his or her foot away from the device
100
. As the user's foot is pulled away from the device
100
, the shoe cover
310
is separated from the device
100
and another shoe cover
310
is delivered to the application portion
80
awaiting the next user. The operation of the device
100
will be described in more detail below.
Turning now specifically to FIG.
2
.
FIG. 2
shows the communication between the package
200
of shoe covers
310
and the device
100
. Specifically, the package
200
has an opening (not shown) that may be aligned with an opening (not shown) in bin
30
. The shoe covers
310
are manually or automatically fed from package
200
to the device
100
through the openings in the package and bin
30
respectively. Automatic feed of the shoe covers
310
may be triggered by sensing the entry of the foot into the device
100
or the user's actuation of a button, lever, trigger or other means known in the art.
FIG. 2
also illustrates the guiding system
40
of the preferred embodiment. The guiding system
40
functions to guide the shoe cover
310
through the device
100
and deliver the shoe covers
310
to the application portion
80
.
In the preferred embodiment, the guiding system
40
includes a funnel
44
and guide members
45
. The funnel
44
comprises a pair of sloped arms
44
a
and
44
b
and neck
44
c
. The shoe covers
310
are drawn from package
200
, through the funnel
44
and neck
44
c
, and onto the guide members
45
. The sloped arms
44
a
and
44
b
of the funnel
44
are mounted on the interior of body
10
. One or both of the arms
44
a
and
44
b
may be biased so as slightly “give” as the shoe covers
310
are drawn though device
100
to prevent tearing or separation of the shoe covers
310
. The “give” may be provided by a spring
47
or other means known in the art.
Preferably, arm
44
a
is pivotally mounted on body
10
using a hinge (not shown) or the like. The spring provides the bias to arm
44
a
. The hinge is set to limit the movement of arm
44
a
in the upward direction. The spring biases arm
44
a
upwards against the natural tendency of arm
44
a
to rotate downward about the hinge.
Although arm
44
a
is shown in
FIG. 2
as being pivotally mounted on body
10
, it is to be understood that funnel
44
merely needs to yield sufficiently to prevent the tearing or separation of the shoe covers
310
. For instance, it is not necessary that only one of arms
44
a
and
44
b
may be mounted on body
10
in the fashion described above. Both arms
44
a
and
44
b
may be spring mounted on body
10
. Moreover, either of arms
44
a
and
44
b
could be manufactured of naturally resilient material providing the “give” required of funnel
44
and not requiring the spring and hinge-mount arrangement of the preferred embodiment.
From the funnel
44
, the shoe covers
310
are fed, again either manually or automatically, to guide members
45
. As shown in
FIG. 3
, the guide members
45
extend through body
10
to application portion
80
. The guide members
45
are shaped, contoured and spaced apart to not only complete the conveyance of the shoe covers
310
to the application portion
80
but to also hold the shoe cover
310
at least substantially open in the application portion
80
facilitating the insertion of a user's foot into the shoe cover
310
. The guide members
45
also preferably include mounting portions
45
b
to mount the guide members
45
to the base
20
using mounting members
22
as shown in FIG.
2
.
In the preferred embodiment of the present invention, the device
100
employs the continuous type disposable shoe cover
310
shown in FIG.
10
. Accordingly, each guide member
45
is designed to fit into each tube
330
of shoe cover
310
. It is important that the tubes
330
of the shoe covers
310
slide along guide members
45
with minimal resistance to avoid the tearing or separation of the shoe covers
310
. Thus, although any elongated shape may be suitable for guide members
45
, it is preferred that the guide members
45
be shafts having cylindrical cross-sections. Additionally, it is preferable that the guide members
45
are made of low-friction materials, such as teflon, or coated with such a material to minimize the risk of tearing or separating the shoe covers
310
.
As mentioned above, the guide members
45
are spaced apart, at least in the application portion
80
of device
100
, to hold open the shoe covers
310
so that the user may insert his or her foot into the shoe cover
310
. In particular, the ends, or holding portions,
45
a
of the guide members
45
are spaced to hold open the shoe covers
310
within the application portion
80
of the device
100
.
In the preferred embodiment using the shoe cover
310
of
FIG. 10
, the spacing of the holding portions
45
a
is sufficient to pull the tube
330
of the shoe cover
310
apart. Yet, since the tubes
330
are separated from the body of the shoe cover
310
along the cut lines
360
, the heel portion
340
and toe portion
350
of the shoe covers
310
are not forced apart by the holding portions
45
a
. The spacing of the holding portions
45
a
pulls apart only the opposing tubes
330
and opposing side walls
320
of the shoe cover
310
, providing the user with an adequate opening in which to insert his foot.
Although the preferred arrangement of the guiding system
40
is described above, it is to be understood by one of ordinary skill in the art that a more intricate or simpler guiding system
40
could be incorporated into the shoe cover
310
applicator device
100
. For instance, the shoe covers
310
could be drawn out of package
200
and delivered to application portion
80
via vacuum power or other mechanically or electrically powered conveying means. Additionally, the funnel guide
44
may be eliminated altogether. And, other suitable conveying means known in the art could be incorporated into the shoe application device in lieu of the guide members
45
. By way of example, as an alternative to guide members
45
, a clamping device could hold the shoe cover
310
in place as it is conveyed through device
100
.
As described above, through the guiding system
40
of the preferred embodiment, the shoe covers
310
are delivered from package
200
to application portion
80
. At application portion
80
, the shoe covers
310
are ready to accommodate the insertion of the user's foot. After the user inserts his or her foot into the shoe cover
310
, the shoe cover
310
is separated or released from the device
100
so that the user may remove the shoe with the shoe cover
310
on. Following the separation or release of the shoe cover
310
, the process starts over (i.e. a new receiving shoe cover
310
is delivered to a receiving position at application portion
80
). This new receiving shoe cover
310
is now ready for the next user to insert his or her foot therein.
To carry out the aforementioned separation, release and delivery operations, the device
100
preferably includes a separation member
85
and a retaining member
75
along with an actuator
70
for actuating each. It is to be understood by one skilled in the art, however, that a single component within the device
100
could replace the separation member
85
and the retaining member
75
to perform their respective functions. Nonetheless, in the preferred embodiment, the retaining member
75
cooperates with the guiding system
40
to selectively restrict or permit the advance of the shoe covers
310
throughout the device
100
and delivery of the shoe covers
310
to application portion
80
. The separation member
85
acts to separate the shoe cover
310
from the device once the shoe cover
310
is on the user's foot.
More specifically with respect to the preferred embodiment, the user may activate an actuator
70
, which in turn triggers the release of a retaining member
75
and activates the separation member
85
. The release of retaining member
75
permits the transport of the shoe cover
310
through the device
100
. In the same way, the release or deactivation of actuator
70
returns retaining member
75
to an active state and deactivates the separation member
85
. While in their active states, retaining member
75
inhibits the movement of the shoe covers
310
through device
100
and separation member
85
separates the shoe cover
310
from device
100
.
Referring now to FIG.
4
.
FIG. 4
shows actuator
70
, retaining member
75
, separation members
85
and how each of these elements cooperates with guide members
45
of the preferred embodiment. In the preferred embodiment of the present invention, the actuator
70
consists of a foot pedal activated when a user's foot depresses the foot pedal. Although actuator
70
is shown as a foot pedal, actuator
70
may be a push button, knob, switch, lever or the like. Additionally, the actuator
70
may be triggered manually, via sensing means (e.g. an optical sensor) or even voice activated. Actuator
70
is employed to release the retaining member
75
and initiate the operation of separation member
85
.
In the preferred embodiment illustrated in
FIG. 4
, both the actuator
70
and guide members
45
extend into the application portion
80
of the device
100
. There, the guide members
45
are spaced apart so as to hold the shoe cover
310
open within the application portion
80
. The application portion
80
includes a foot tray
81
. The guide members
45
preferably run along the longitudinal edges of the foot tray
81
while the actuator
70
extends over the foot tray
81
between the guide members
45
.
The foot tray
81
may be configured to receive shoe types of various shapes and sizes.
FIG. 7
shows a close-up of the preferred embodiment of foot tray
81
. As can be seen in the Figure, the foot tray
81
may comprise a channel
83
for receiving the sole of a shoe and channel
84
within channel
83
for receiving a high-heel portion of a shoe. Alternatively, the foot tray
81
could include interchangeable platforms of varying configurations to accept a wide assortment of different shoe sole shapes according to the footwear requirements of the environment within which the device
100
is used.
Additionally, the preferred embodiment, a toe guide
82
is positioned in application portion
80
. The toe guide
82
is generally configured to receive the front (toe) portion of the user's shoe. Preferably, the toe guide
82
is coupled to retaining member
75
, as shown in FIG.
5
.
With the guide members
45
holding the shoe cover
310
open in the receiving position within the application portion
80
, the shoe cover
310
overlies both the actuator
70
and the foot tray
81
. Thus, upon insertion of a shoe into the receiving shoe cover
310
, actuator
70
is depressed (activated) and the shoe rests upon the foot tray
81
substantially surrounded by the receiving shoe cover
310
. The activation of the actuator
70
releases the retaining member
75
and initiates the operation of the separation member
85
. The release of retaining member
75
along with the activation of separation member
85
permits the withdrawal of the user's foot from the foot tray
81
with the shoe cover
310
substantially surrounding the shoe.
In the preferred embodiment, separation member
85
includes of a pair of cutting blades positioned at the mounting portions
45
b
of the guide members
45
, as shown in FIG.
6
. As the user slides his or her foot off the foot tray
81
, the separation member
85
separates the shoe cover
1310
from device
100
. Particularly, the cutting blades slice open the tubes
330
of the shoe cover
310
that hold the shoe cover
310
on guide members
45
as the shoe cover
310
passes the cutting blades on the mounting portions
45
b
of guide members
45
. Thus, the shoe cover
310
is separated from the device
100
and is free to contract around the wearer's shoe.
Although the preferred embodiment describes the separation member
85
as a pair of cutting blades, it is to be understood that any appropriate means known in the art of separating the shoe cover
310
from the device
100
may be utilized. It should be evident to one skilled in the art that various separating members are available to cooperate with any suitable means known in the art for delivering the shoe covers
310
to the application portion
80
, including the guide members
45
of the preferred embodiment.
As mentioned above, actuator
70
operates to release retaining member
75
. The preferred linkage system is illustrated in detail in FIG.
9
. However, it is to be understood by one skilled in the art that any mechanical or electrical connection may be used to translate the activation of actuator
70
into the release of retaining member
75
.
Turning now to preferred embodiment shown in
FIG. 9
, body
10
houses a linkage system
50
and actuator
70
. The linkage system
50
preferably includes a rectangular tray
51
with folded-up edges
51
a
and
51
b
, a pair of intermediate links
52
having apertures
52
a
and
52
b
at each end and a retaining member
75
having a pair of mounting members
54
extending from each end, as shown in FIG.
5
. Apertures
51
c
,
51
d
,
51
e
and
51
f
are provided in the folded-up edges
51
a
and
51
b
of rectangular tray
51
. Each of the mounting members
54
includes a pair of apertures
55
a
,
55
b
,
55
c
, and
55
d
. The actuator
70
is coupled to the rectangular tray
51
, which in turn is coupled to an end of the intermediate link
52
. The opposite end of the intermediate link
52
is coupled to retaining member
75
.
The preferred linkage system
50
also comprises a U-shaped mounting bracket
61
, mounting rods
62
and
67
, connecting rods
63
and
64
, limiting rod
65
and biasing member
66
. Mounting bracket
61
is fixed to the inside of body
10
. Mounting rod
62
passes through apertures
55
c
and
55
d
to couple retaining member
75
to mounting bracket
61
so that the retaining member
75
may rotate about mounting rod
62
. Mounting rod
67
passes through apertures
51
e
and
51
f
of rectangular tray
51
to couple the rectangular tray
51
to the mounting bracket
61
. Thusly, one longitudinal edge of the rectangular tray
51
may rotate about mounting rod
67
. Connecting rod
63
passes through apertures
52
b
of each intermediate links
52
and through apertures
55
a
and
55
b
of the mounting members
54
to pivotally couple the intermediate links
52
and the retaining member
75
. Thus, intermediate links
52
rotate relative to the retaining member
75
. Finally, connecting rod
64
passes through apertures
52
a
of intermediate links
52
and apertures
51
c
and
51
d
in the rectangular tray
51
, coupling each of the intermediate links
52
to the folded-up edges
51
a
and
51
b
of the rectangular tray
51
.
The actuator
70
, may be coupled, or fixed, at one end, to the rectangular tray
51
so that the motion imparted to the actuator
70
is transferred to rectangular tray
51
. The other end of actuator
70
extends out of body
10
and is freestanding. The range of motion of both rectangular tray
51
and actuator
70
is limited by biasing member
66
and limiting rod
65
. Biasing member
66
, shown in
FIG. 3
, is preferably but not limited to, a spring, and is mounted to both the mounting bracket
61
and the rectangular tray
51
. The spring
66
is set to restrain the upward movement of rectangular tray
51
. The limiting rod
65
is mounted at each end to mounting bracket
61
above the linkage system
50
to limit the upward movement of linkage system
50
and in turn the upward movement of the actuator
70
.
The body
10
and base
20
of the shoe cover application device include a removable exterior casing
90
. Casing
90
serves as a protective cover to minimize contamination of the shoe covers
310
within the shoe cover application device
100
. Optionally, a retractable cover (not shown) conceals the application portion
80
of the shoe cover application device
100
. Such a cover could comprise manually activated or automated sliding or pivoting panels, or a removable cap or casing. With such a cover, the shoe covers
310
are not exposed to contaminants when they are situated in the application portion
80
.
The operation of the preferred embodiment will now be described. The continuous type shoe cover
310
is loaded into the shoe cover application device
100
as each fresh package
200
is inserted into bin
30
. The package
200
is opened at opening
201
and set into bin
30
so that opening
201
aligns with opening
35
in bin
30
. Removable casing
90
is removed and the first continuous disposable shoe cover
310
in the lineal
300
is manually, or by other means, pulled from package
200
. The continuous shoe cover lineal
300
is then fed through the neck
45
of funnel guide
44
. While retaining member
75
is raised to a non-retaining position, each tube
330
of the shoe cover
310
is then set on the each guide pipe
45
and drawn through the shoe application device
100
. The shoe cover
310
is fed along guide pipe
45
until the shoe cover
310
overlays the application portion
80
and actuator
70
. The spacing of the guide members
45
at holding portions
45
a
hold open the shoe cover
310
against the bias of the elastic member
370
so that the user may place his or her foot inside it. Although the guide members
45
are illustrated at a particular spacing, it is to be understood by one skilled in the art that the spacing of the guide members
45
may be adjusted, or adjustable, to accommodate shoes of various widths. Once the shoe cover
310
is in position to be applied to a shoe within the application portion
80
, the retaining member
75
is released and allowed to return to its natural retaining position; precluding the shoe cover lineal
300
from advancing through the shoe application device
100
. The casing
90
may then be reattached to the shoe application device
100
.
Alternatively, the shoe covers
310
may be automatically drawn out of the package
200
using vacuum power or other means known in the art and positioned on guiding system
40
to be fed through the device
100
. Moreover, shoe covers
310
within package
200
may alternatively be interlocked so that as one is removed from the package
200
and positioned on guiding system
40
, the next shoe cover
310
is drawn out of the package
200
ready for placement upon the guiding system
40
.
Once the user is ready to wear the shoe cover
310
, he actuates the freestanding end of the actuator
70
. Preferably, the user steps on a pedal located below the receiving shoe cover
310
within the application portion
80
; depressing the pedal or freestanding end of the actuator
70
into channel
83
so that the user's foot is within the receiving shoe cover
310
. The pressing of the pedal causes the front longitudinal edge of the rectangular tray
51
to move downward as the rear longitudinal edge of the rectangular tray
51
rotates about mounting rod
67
. Connecting rod
64
does not permit intermediate links
52
from rotating relative to rectangular tray
51
. Thus, the downward motion of rectangular tray
51
is transmitted to intermediate links
52
. As the intermediate links
52
move downward, retaining member
75
pivots about the longitudinal axis mounting rod
62
since mounting rod
62
is fixed to mounting bracket
61
. However, connecting rod
63
is not fixed to the mounting bracket
61
. Therefore, as retaining member
75
pivots about the longitudinal axis of mounting rod
62
, mounting members
54
of the retaining member
75
rotate relative to intermediate links
52
. Through this rotation, retaining member
75
is moved to a non-retaining position as actuator
70
is depressed.
At this point, the user's foot is in the receiving shoe cover
310
and the retaining member
75
is in a non-retaining position. As long as the retaining member
75
is in a non-retaining position, the continuous shoe cover lineal
300
is free to advance along the guide members
45
. The user then pulls his or her foot, enclosed by the shoe cover
310
, off of the foot tray
81
allowing the elastic member
370
to contract and substantially enclose the user's shoe. Upon the user's action, the actuator
70
is released which, through linkage system
50
and mounting system
60
, causes the retaining member
75
to rotate to a retaining position. As the user pulls his or her shoe off of foot tray
81
with the shoe cover
310
on the shoe, separation member
85
cut away the tubes
330
of the receiving shoe cover
310
from the holding portions
45
a
of the guide members
45
. Simultaneously, the receiving shoe cover
310
is torn away from the shoe cover lineal
300
at the perforation
380
; leaving the subsequent shoe cover
310
in a receiving position upon the holding portions
45
a
of the guide members
45
.
As an alternative to guide members
45
, the shoe cover
310
could be held in place as it is conveyed through the shoe application device
100
by a clamping device. A clamp releasing mechanism or the like positioned at application portion
80
would be used instead of separation member
85
operating in conjunction with retaining member
75
as a separating system.
The preferred embodiment has been described above. However, it is to be understood that various modifications and additional features are available to one of ordinary skill in the art. For example, although a mechanically driven shoe cover applicator device has been described in detail, the continuous shoe cover lineal could be loaded, fed and driven through the device using any apt mechanical or electronic means including vacuum or hydraulic power. The device may coin operated, actuated via a push-button, hand lever, infrared sensors or any other suitable means of actuation. Additionally, handrails may be provided to help the user maintain his or her balance as they use the device.
It should also be understood that various changes and substitutes and alterations could be made to the invention without departing from the spirit and the scope of the invention as defined in the following claims.
