TECHNICAL FIELD
[0001] The present disclosure relates to a blind cleaning device.
BACKGROUND
[0002] Window blinds are commonly installed in various spaces, such as commercial buildings
or a residential space as part of an interior decoration of such spaces. The window
blinds are used to regulate an amount of desired light in the space where they are
installed. Further, the window blinds may block direct sunlight, promote energy conservation,
and provide privacy.
[0003] The window blinds typically consist of multiple lamellae that are arranged in parallel.
The lamellae are spaced apart from each other by a predefined distance. Generally,
a number of controlling means are provided for controlling an angular position of
the lamellae of the window blinds, such that the lamellae may be angularly rotated
between an open position, which permits maximum passage of light through the window
blinds, and a closed position, which provides maximum blockage of light through the
window blinds. Over a period of time, dirt, dust, debris, particulate matter, and
the like, may accumulate on the window blinds. Further, pathogens may also be present
on the window blinds. Thus, such window blinds may have to be periodically cleaned.
In applications where a large number of window blinds are installed, such as in the
commercial buildings, individual cleaning of each lamella becomes a time consuming
and laborious task.
[0004] Some cleaning devices, such as brushes, are available in the market to remove particles
accumulated on the lamellae of the window blinds. These brushes typical use a friction
surface and/or a vacuum to dislodge particles accumulated on the lamellae of the window
blinds. However, some particles are well adhered to the surfaces of the lamellae which
may be difficult to remove with such brushes. In some cases, greasy residues are needed
to be removed from the lamellae. Further, particles accumulated on the lamellae of
the window blinds tend to adhere to the greasy residues. Such greasy residues may
not be completely removed with brushes that involve techniques such as friction and/or
vacuum. Thus, there is a need for an improved cleaning device to clean the lamellae
of the window blinds effectively, efficiently, and without causing user fatigue.
[0005] An example of a shutter slat cleaning accessory is provided in
U.S. Patent Application 2017/0,127,891 (hereinafter referred to as '891 reference). The '891 reference discloses a cleaning
tool for manually cleaning a variety of shutter slat types having a complex profile.
The '891 reference includes various configurations of a cleaning glove and a modular
system of various cleaning accessories that can be connected to the glove and easily
disconnected therefrom. However, the cleaning accessory of the '891 reference includes
multiple parts that are complex in design and assembly. Further, the cleaning accessory
is cumbersome to use during cleaning process. Moreover, the cleaning tool seems short
of providing any arrangement which allows to have convenient or controlled cleaning
by application of any fluid (say water) associated with the cleaning tool.
SUMMARY
[0006] In view of the above, it is an objective of the present disclosure to solve or at
least reduce the drawbacks discussed above. The objective is at least partially achieved
by a new design of a blind cleaning device. The blind cleaning device includes a body
defining a bracket. The blind cleaning device also includes a pair of bristle plates
coupled with the bracket of the body. The body is coupled with a fluid connection
which provides a fluid. The blind cleaning device further includes a pair of bristle
brushes to couple with the pair of the bristle plates. Each of the pair of bristle
brushes includes a plurality of bristles. The blind cleaning device is characterized
in that the pair of bristle brushes are coupled with the pair of the bristle plates
such that the pair of bristle brushes contact each other to define a cleaning room
with the pair of the bristle plates. The fluid connection supplies the fluid into
the cleaning room.
[0007] Thus, the present disclosure provides an improved blind cleaning device for desired
cleaning applications, such as to clean the lamellae of window blinds effectively
and efficiently. The blind cleaning device allows desired cleaning of the lamellae
of the window blinds with the fluid connection providing the fluid, such as water.
Further, the cleaning room avoids splashing of the fluid. Particularly, the cleaning
room of the present disclosure allows to avoid splashing of the fluid around or through
the bristle brushes. It should be noted that the blind cleaning device can be used
for cleaning other components apart from window blinds, as applicable.
[0008] According to an embodiment of the present disclosure, the body is removably coupled
with a fluid supply device for supply of the fluid. Such a removable attachment of
the fluid supply device provides flexibility in terms of cleaning the lamellae of
the window blinds with or without the fluid. The fluid from the fluid supply device
can be used to provide improved cleaning of various surfaces with fluids. This arrangement
also allows removable coupling of different attachments, such as brushes, showers,
nozzle, and the like, with the fluid supply device.
[0009] According to an embodiment of the present disclosure, the blind cleaning device includes
a rotatable joint between the body and the fluid supply device. The rotatable joint
between the body and the fluid supply device provides improved ergonomics during cleaning
(say of a soil-deep window). The rotatable joint allows angular disposition of the
fluid supply device with respect to the body. Specifically, the fluid supply device
may be attached horizontally or vertically. In a horizontal position of the fluid
supply device, the user may feel less weight during a cleaning operation. Further,
a vertical position of the fluid supply device may create less disturbance during
the cleaning operation.
[0010] According to an embodiment of the present disclosure, a hose connector is removably
attached to the fluid supply device. The hose connector allows connection of the fluid
supply device with the fluid connection or with a hose.
[0011] According to an embodiment of the present disclosure, at least one of the pair of
bristle plates define one or more openings to allow discharge of the fluid therefrom.
The one or more openings may be provided in a central portion of the bristle plates
to allow discharge of the fluid, such as water, through the openings.
[0012] According to an embodiment of the present disclosure, the pair of bristle plates
are substantially parallel and include a spring-loaded mechanism. This arrangement
may allow cleaning of both sides of the lamella of the window blinds at the same time,
thereby reducing user effort. Further, the spring-loaded mechanism may allow any adjustments
or movement of the pair of bristle plates and thereby provide efficient cleaning of
the lamellae. According to an embodiment of the present disclosure, the pair of bristle
plates is height adjustable to change a distance between the pair of bristle plates.
With the height adjustable arrangement of the bristle plates, the distance between
the bristle plates may be adjusted if the bristles wear out. This height adjustable
nature of the bristle plates may be due to the spring-loaded mechanism.
[0013] According to an embodiment of the present disclosure, the body includes an adjustable
limitation stop for different lamella width. In some embodiments, the connecting portion
includes the adjustable limitation stop. The adjustable limitation stop of the blind
cleaning device may be adjusted for different lamella width, thereby making the blind
cleaning device versatile and adaptable in use. The limitation stop may accommodate
a jet that promotes efficient cleaning and water saving. The jet may be flat or conical.
Further, different types of fluid jet, such as flat fluid jet, conical fluid jet,
and the like, may be obtained by adjusting the limitation stop.
[0014] According to an embodiment of the present disclosure, the pair of bristle brushes
are removably coupled with the pair of the bristle plates. This arrangement allows
removable coupling of different types of bristle brushes for different window blinds
and also allows replacement of the bristle brushes, such as for regular service and
the like.
[0015] Other features and aspects of this disclosure will be apparent from the following
description and the accompanying drawings.

[0019] FIG. 1 is a perspective view of a blind cleaning device 100. The blind cleaning device
100 may be used for different cleaning applications, such as to clean a number of
lamellae (not shown) of a window blind (not shown). The present disclosure illustrates
a cleaning device as the blind cleaning device
100, however actual implementation of the present disclosure may be applied with any cleaning
device making use of one or more brushes, bristles and the like. The blind cleaning
device
100 includes a body
102 defining a bracket
104. The body
102 may be manufactured from a plastic, a metal, and the like. The body
102 may be embodied as a single piece unit or the body
102 may include multiple separate parts that are joined together to form the body
102. The body
102 may be coupled with different types of cleaning attachments, such as, brushes, showers,
nozzle, and the like. The body
102 is coupled with a fluid connection
103 which provides a fluid towards the blind cleaning device
100. The fluid connection may include a tap, pump, and the like. Further, the fluid may
include water or any other cleaning fluid.
[0020] Referring to
FIG. 2, the bracket
104 defines a first end
106 and a second end
108. Further, the bracket
104 of the body
102 includes a generally U-shaped structure herein. It should be noted that the bracket
104 may include any other shape and size, without limiting the scope of the present disclosure.
The bracket
104 includes a first surface
110. The bracket
104 also includes a second surface
112 (shown in
FIG. 5)
. The bracket
104 also includes a number of projections
114 (shown in
FIG. 5) on the second surface
112. In the illustrated example, the bracket
104 includes four projections
114. The body
102 includes an inlet portion
118. The inlet portion
118 includes a threaded profile. Further, the inlet portion
118 defines a through-hole
144.
[0021] FIG. 3 shows the blind cleaning device
100, in accordance with an embodiment of the present disclosure. In this embodiment, the
body
102 includes a distributor
127. The distributor
127 defines a T-shaped structure, although other shapes, types, dimensions, structure
have been contemplated and are well within the scope. The distributor
127 includes an inlet channel
129 and two outlet channels
131. The outlet channels
131 are substantially perpendicular to the inlet channel
129. The inlet channel
129 is fluidly coupled to the inlet portion
118 of the body
102 for a fluid flow
"F" (or simply the fluid), such as water for cleaning, therethrough. Further, the outlet
channels
131, receive the fluid flow
"F" from the inlet channel
129 to supply the fluid flow
"F" to each bristle plate
134, 136. Each bristle plate
134,136 defines an inlet opening
135 and a number of outlet openings
137. The fluid flow
"F" from the outlet channels
131 of the distributor
127 enters the bristle plates
134, 136 through the inlet opening
135. Further, the fluid flow
"F" is then discharged through the outlet openings
137, such as for applications involving cleaning of the lamella of the window blind and
the like.
[0022] The present disclosure refers to the "fluid" or the "fluid flow" which have been
used interchangeably for ease of explanation and understanding. The fluid flow
"F" through the blind cleaning device
100 is illustrated in
FIG. 3 for detail flow from a hose connector
130 to a fluid supply device
124, and then to the distributor
127 of the body
102. This fluid flow
"F" then splits in the distributor
127 to move towards each bristle plate
134, 136, as illustrated in
FIG. 3.
[0023] Further, the body
102 also includes an adjustable limitation stop
122 (shown in
FIG. 3) for different lamella width. The limitation stop
122 may be integrated and work with the distributor
127 to allow splitting of the fluid i.e., water from the inlet channel
129 to the outlet channels
131. In some embodiments, the blind cleaning device
100 may not include any limitation stop
122 and make application of the distributor
127. In some embodiments, a connecting portion
142 (shown in
FIG. 4) includes the adjustable limitation stop
122. The limitation stop
122 includes a cylindrical body defining an inlet (not shown) and an outlet (not shown).
The inlet is fluidly coupled to the inlet portion
118 of the body
102 to supply fluid, such as water for cleaning, therethrough. Further, the fluid is
discharged through the outlet of the limitation stop
122. The limitation stop
122 may accommodate a jet that allows discharge of fluid therethrough. Further, the limitation
stop
122 can be adjusted for different lamella width. In some examples, the limitation stop
122 can be adjusted to accommodate the lamella width that approximately lies in a range
of about 40 Millimeters (mm) to about 100 mm. Furthermore, the jet may be flat or
conical. The limitation stop
122 may be adjusted to obtain different types of fluid jet, such as flat fluid jet, conical
fluid jet, and the like. Specifically, the limitation stop
122 can be rotated to adjust a pattern of the jet. Further, the body
102 is removably coupled with the fluid supply device
124 for supply of the fluid. The inlet portion
118 of the body
102 allows removable coupling of the body
102 with the fluid supply device
124 using a rotatable joint
126.
[0024] The blind cleaning device
100 also includes the fluid supply device
124. The fluid supply device
124 includes an actuator
128 to allow passage of the fluid towards the body
102 of the blind cleaning device
100. When actuated, the actuator
128 allows passage of fluid therethrough. It should be noted that the fluid supply device
124 may include any arrangement for passage of the fluid towards the body
102 of the blind cleaning device
100, such as a button, a knob, a handle, and the like. The fluid supply device
124 includes a first inlet
116 and a first outlet
120. Further, the hose connector
130 is removably attached to the fluid supply device
124. The hose connector
130 is removably attached to the first inlet
116 of the fluid supply device
124. The hose connector
130 includes a threaded section
132 to removably couple a hose pipe (not shown) with the hose connector
130. The hose pipe may supply the fluid from the fluid connection
103 towards the blind cleaning device
100.
[0025] Further, the blind cleaning device
100 includes the rotatable joint
126 between the body
102 and the fluid supply device
124. The rotatable joint
126 includes a cylindrical body, a joint inlet (not shown), and a joint outlet (not shown).
The joint inlet is connected to the fluid supply device
124 and the joint outlet is removably coupled with the inlet portion
118 of the body
102. The joint outlet may be partially received through the through-holes
144. Further, the joint outlet may include a threaded section (not shown) for removable
coupling with the inlet portion
118 of the body
102. The rotatable joint
126 allows coupling of the body
102 of the blind cleaning device
100 with the fluid supply device
124 at various angles. The rotatable joint
126 between the body
102 and the fluid supply device
124 provides improved ergonomics during cleaning, such as of a soil-deep window (not
shown).
[0026] In a first position or a vertical position, as illustrated in
FIGS. 1 to 3, the rotatable joint
126 allows vertical coupling of the fluid supply device
124 with the body
102 of the blind cleaning device
100. The first position of the fluid supply device
124 may create less disturbance for the user during the cleaning operation. Referring
to
FIG. 4, in a second position or a horizontal position, the rotatable joint
126 allows horizontal coupling of the fluid supply device
124 with the body
102 of the blind cleaning device
100. In the second position of the fluid supply device
124, the user may feel less weight during a cleaning operation. Further, the first/vertical
and the second/horizontal positions of the rotatable joint
126 may allow different positions, angles, ergonomic styles for cleaning by the body
102 of the blind cleaning device
100. Further, the present disclosure illustrates and discusses the first/vertical and
the second/horizontal positions, however actual implementation may have many and other
positions in between the first/vertical and the second/horizontal positions of the
rotatable joint
126.
[0027] Referring to
FIG. 5, the blind cleaning device
100 also includes a pair of bristle plates
134,136 to couple with the bracket
104 of the body
102. Specifically, the blind cleaning device
100 includes the first bristle plate
134 and the second bristle plate
136 facing the first bristle plate
134 and spaced apart from the first bristle plate
134. The pair of bristle plates
134, 136 may be similar in shape and size. Alternatively, the bristle plates
134, 136 may include different shape and size. The bristle plate
134, 136 defines a first plate surface
138 and a second plate surface
140. The first plate surface
138 of the bristle plate
134, 136 includes a generally planar profile. The first plate surface
138 includes a number receiving slots
146 to receive the projections
114 of the bracket
104. The second plate surface
140 of the bristle plates
134, 136 includes a curved profile. The pair of bristle plates
134, 136 may be coupled to the bracket
104 using a snap-fit connection. It should be noted that the pair of bristle plates
134, 136 and the bracket
104 may be connected by any other means, without limiting the scope of the present disclosure.
[0028] The pair of bristle plates
134, 136 are connected with each other by the connecting portion
142. In the illustrated example, the pair of bristle plates
134, 136 and the connecting portion
142 are embodied as an integral unit. Alternatively, the pair of bristle plates
134, 136 and the connecting portion
142 may be embodied as separate parts that are joined together. The pair of bristle plates
134, 136 and the connecting portion
142 form a generally U-shaped structure.
[0029] The pair of bristle plates
134, 136 are substantially parallel and include a spring-loaded mechanism (not shown). The
spring-loaded mechanism of the bristle plates
134, 136 may allow some adjustment or movements thereof, and may exert a pressure on the lamella
of the window blinds to effectively clean dirt particles from a surface of the lamella.
Further, the spring-loaded mechanism and the fluid jet may allow efficient cleaning
of greasy residue on the lamella surface.
[0030] As shown in
FIG. 5, the blind cleaning device
100 further includes a pair of bristle brushes
150 coupled with the pair of the bristle plates
134, 136. The pair of bristle brushes
150 are disposed on the second plate surface
140 and extend therefrom. Each of the pair of bristle brushes
150 includes the plurality of bristles
152. The pair of bristles
152 of the pair of bristle brushes
150 overlap each other. The bristles
152 may be tilted and arranged in a shape
154 to suit the shape of the lamellae of the window blind. This arrangement may allow
uniform cleaning of the lamella surface. The bristles
152 may include a first row of bristles that are disposed on an outer side of the bristle
brushes
150 and a second row of bristles that are disposed on an inner side of the bristle brushes
150. The first row of bristles may include soft bristles and the second row of bristles
may include hard bristles. The first row of bristles and the second row of bristles
may be in contact with each other.
[0031] The pair of bristle brushes
150 are removably coupled with the pair of bristle plates
134, 136. More particularly, each bristle plate
134, 136 may include a bristle fixation element
155 (as shown in
FIG. 3) to removably couple the pair of bristle brushes
150. The bristle fixation element
155 can be removably coupled to the bristle plates
134, 136. The bristle fixation element
155 may be made up of a soft plastic material. The bristle fixation element
155 allows removable coupling of the pair of bristle brushes
150 with the bristle plates
134, 136. The removable coupling of the pair of bristle brushes
150 allows coupling of different types of bristle brushes, or removal during service
intervals and the like. The bristles
152 of each bristle brush
134, 136 may be manufactured using a synthetic material, such as nylon. It should be noted
that the bristles
152 may include any other material, without limiting the scope of the present invention.
[0032] Referring to
FIGS. 6A and
6B, different views of the blind cleaning device
100 is illustrated. As shown, at least one of the pair of bristle plates
134, 136 (see
FIGS. 6A and
6B, respectively) define one or more openings
148 to allow discharge of the fluid therefrom. The one or more openings
148 are specifically provided to allow discharge or drainage of any excess amount or
flow of the fluid during application of the blind cleaning device
100. Such discharge or drainage of the fluid will take place, through the one or more
openings
148, substantially perpendicular to the first and second bristle plates
134, 136 leading to a simple, user-friendly, and splash-proof cleaning application by the
blind cleaning device
100. In the illustrated example, each of the first and second bristle plates
134, 136 includes the opening
148. Alternatively, any one of the first and second bristle plates
134, 136 may include the opening
148. The openings
148 of each bristle plate
134, 136 may be identical in shape and size. The openings
148 are centrally disposed within the bristle plates
134, 136, however, actual implementations may have any position, type, size, placement, or
number of the openings
148. The fluid jet directed through the distributor
127 (with or without the limitation stop
122) may split through the distributor
127 to discharge the fluid from the openings
148 provided on the bristle plates
134, 136 after cleaning the lamella surface. The pair of bristle brushes
150 are coupled with the pair of the bristle plates
134, 136 such that the pair of bristle brushes
150 contact each other to define a cleaning room
156 (shown in
FIG. 6B) with the pair of the bristle plates
134, 136. Specifically, the pair of bristle brushes
150 overlap each other, such that minimum efforts may be required to clean the lamella,
and there may not be any undesired fluid spillage through or around the pair of bristle
brushes
150. Further, the fluid connection supplies the fluid into the cleaning room
156. The cleaning room
156 defines an axis
"A" (shown in
FIG. 3) normal to each opening
148 of the bristle plates
134, 136. Further, the cleaning room
156 may allow removal or discharge of the fluid (say water) therethrough. Particularly,
the cleaning room
156 may allow the fluid to discharge along the axis
"A" therethrough, to check or avoid any undesired splashing or movement of the fluid
substantially perpendicular to the axis
"A". Moreover, the arrangement of bristles
152 and the cleaning room
156 avoids splashing of fluid during cleaning process. Further, a front side
158 of the pair of bristle brushes
150 may be covered with a textile material, a rubber material, a plastic sheet, a foil
sheet, and the like, for additional protection against the splashing of fluid.
[0033] The cleaning room
156 of the present disclosure is defined between the pair of the bristle plates
134, 136 and the pair of bristle brushes
150. This may create a rectangular, square or any other geometrical shaped volume of the
cleaning room
156, which allows to receive and hold the fluid during cleaning by the blind cleaning
device
100. Further, the cleaning room
156 may allow discharge of the fluid through the opening
148, while avoiding any undesired spillage or discharge of the liquid through or around
the pair of bristle brushes
150.
[0034] Further, the pair of bristle plates
134, 136 is height adjustable to change a distance
"D" between the pair of bristle plates
134, 136. The height adjustable bristle plates
134, 136 may be used to adjust the distance
"D" between the pair of bristle plates
134, 136 when the plurality of bristles
152 of the pair of bristle brushes
150 wear out. More particularly, in an event of wear out of the bristles
152, the bristle plates
134, 136 may be disposed closer to each other to compensate for a reduction in a length of
the bristles
152. This height adjustable nature of the bristle plates
134, 136 may be due to the spring-loaded mechanism. In some embodiments, the height adjustable
nature of the pair of bristle plates
134,136 may allow to change the distance
"D" and thereby change dimensions (i.e. volume) of the cleaning room
156. Such change in the dimensions of the cleaning room
156 may be suitable for different applications or operational requirements, such as to
control a rate of the fluid leaving the cleaning room
156 (say along the axis
"A"). In an alternate example, the bracket
104 of the blind cleaning device
100 may include a rectangular shape with rounded corners instead of the U-shaped structure.
Further, in such an example, each bristle plate
134, 136 may be directly coupled with the rectangular bracket
104 using a number of mechanical fasteners and the connecting portion
142 may be omitted.
[0035] The present disclosure provides the improved blind cleaning device
100 to clean the lamellae of window blinds effectively and efficiently. The blind cleaning
device
100 allows cleaning of the window blinds with or without fluid. Further, the blind cleaning
device
100 allows removable coupling of different attachments, such as brushes, showers, nozzle,
and the like. The blind cleaning device
100 includes fewer parts and can be easily assembled without requiring additional tools.
Further, the blind cleaning device
100 is easy and convenient to use for users and does not cause user fatigue.
[0036] In the drawings and specification, there have been disclosed preferred embodiments
and examples of the disclosure and, although specific terms are employed, they are
used in a generic and descriptive sense only and not for the purpose of limitation
of the scope of the disclosure being set forth in the following claims.
