Description
FIELD OF ART
[0001] The present invention relates to a surface treating device
formed by assembling a small number of members having simple
configuration, that can be used as a lustering-agent applicator
used for lustering car bodies or tires, furniture, etc. as well as
a cleaner, an eraser for a blackboard or other such device.
BACKGROUND ART
[0002] A great number of brushes or applicators having a grip to be
held by a user have heretofore been proposed.
[0003] Typical of the proposed brushes are represented by
toothbrushes, clothesbrushes, etc. having a treating portion
constituted of numerous bristle members. Generally, the treating
portion has a relatively small area or is rod-shaped. The major
structural feature of the treating portion is that the proximal
ends of the bristle members are totally adhered and fixed to a base
by means of an adhesive agent.
[0004] The proposed applicators have a treating portion constituted
of various kinds of materials. Materials capable of retaining a
liquid composition therein include a continuously foamed body, such
as sponge, and a continuously foamed body coated with cloth, felt
or the like. The treating portion generally has a relatively large
area. The major structural feature of the treating portion
constituted of sponge, for example, is that the back surface of the
sponge is adhered and fixed to a base by means of an adhesive
agent. When the treating portion is constituted of sponge coated
with cloth, for example, the side edges of the cloth are fixed to
the peripheral edge of a base by means of an adhesive agent or
metal fittings. So-configured applicators are disclosed in JU-A
54-177764, JU-A 54-177766, JU-B 57-46939, JU-B 59-9742, JP-B
60-2046 and JD-B 559923.
[0005] However, since the conventional brushes or applicators are
fabricated using an adhesive agent, they cannot be used until the
adhesive agent sets. In addition, the adhesive agent contains an
organic solvent. For these reasons, the productivity thereof is not
good. To be specific, the material of the treating portion easily
falls out before the adhesive agent sets. Therefore, a step of
setting the adhesive agent is required. In addition, the adhesive
agent contains an organic solvent that is flammable and harmful to
the human body. Therefore, it is necessary to install an exhausting
unit and pay strict attention to fire prevention.
[0006] Some structures using no adhesive agent, such as an eraser
for a blackboard, also have heretofore been proposed. In this case,
a strap of metal has to be attached and fixed to the peripheral
edge of a base by striking metal fittings such as rivets. Since the
assembling work requires special treatments, as described above,
the productivity of the devices is not good and the production cost
is high.
[0007] On the other hand, the work of lustering car bodies is to
coat a thin film of a water-repellent treating agent, such as
liquid or semisolid wax onto the car body surface. A car owner has
to assemble a set of materials including an applicator such as a
spongy member, a water-repellent treating agent, a container for
the treating agent, a cloth member for thinly applying and wiping
off the treating agent and disposable gloves for carrying out this
work. This set is bulky and takes up a large space. If always kept
in a car trunk, it is likely to be a nuisance, especially if not
frequently used.
[0008] In view of the above, the present invention has been
accomplished and one object thereof is to provide a surface
treating device that can be easily fabricated with high
productivity without requiring the use of an adhesive agent or the
work of welding or other such attaching treatment.
[0009] Another object of the present invention is to provide a
surface treating device advantageously usable for the work of
lustering car bodies without requiring the use of an applicator,
wax, a cloth member, etc.
DISCLOSURE OF THE INVENTION
[0010] To attain the above objects, the present invention provides
a surface treating device comprising a material that constitutes a
treating portion of a continuously foamed body coated with a
fibrous film, a holder that has a base for supporting the treating
portion thereon and an annular groove provided in an inside
peripheral surface thereof with an engaging structure, and an
annular engaging member that has a distal end forcibly fitting an
end of the treating portion into the annular groove of the holder
to support the treating portion on and fix it integrally to the
base.
[0011] The continuously foamed body may be impregnated with wax,
detergent or like agent.
[0012] The holder may be provided with a hollow cylindrical grip
portion having in an open end face thereof a ring groove and with a
base member having on a peripheral edge thereof a downwardly
overhanging portion that constitutes an engaging structure fitted
on the open end face of the grip portion.
[0013] The surface treating device may be provided further with a
cover member having a bulged portion for covering the treating
portion.
[0014] As described above, the surface treating device according to
the present invention comprises a material constituting a treating
portion, a holder and an annular engaging member. These component
members can be assembled with ease into a surface treating device,
without use of adhesive agent or other such agent, by a simple
operation of forcing the treating portion into an annular groove of
the holder and fitting the annular engaging member in the annular
groove. Thus, the present invention can provide a surface treating
device that can be produced with high efficiency and used with high
safety.
[0015] The surface treating device of the present invention having
a treating portion impregnated with wax can be used directly for
the work of lustering car bodies without requiring separate
preparation of an applicator, wax and a cloth member. Thus, the
present invention can provide a surface treating device that can be
put to very advantageous and practical use.

BEST MODE FOR EMBODYING THE INVENTION
[0023] FIGS. 1 to 3 illustrate a first embodiment of the surface
treating device according to the present invention. The device is a
wet-type one usable advantageously as an applicator for applying a
lustering agent to car bodies and comprises a material constituting
a treating portion 11 of a continuously foamed soft body 2 of
urethane etc. that is so-called sponge and a fibrous film 3 coated
on the surface of the body. The continuously foamed body 2 occludes
therein a lustering agent such as semisolid wax or like agent. (A
surface treating device having a treating portion impregnated with
wax, detergent or the like agent is called a wet-type one, and one
having a treating portion impregnated with no such agent is called
a dry-type one throughout the description.) The surface treating
device (lustering-agent applicator) 1 fundamentally comprises the
material (2 and 3), an annular engaging member 4 and a holder 5.
Since the continuously foamed body 2 occludes a lustering agent
therein, as described above, the material is provided with a cover
member 6 for covering the material to prevent accidental adherence
of wax before the use of the device and volatilization of the
lustering agent, such as wax, detergent, etc., occluded in the
material.
[0024] Each of the component members will be described
hereinafter.
[0025] The material constituting the treating portion 11 coming in
contact with a surface to be treated (a car body surface in this
case) when using the surface treating device, comprises the
continuously foamed body 2 and the fibrous film 3 coated on the
surface of the body. The continuously foamed body 2 is impregnated
with nothing when applied to a dry-type surface treating device,
but is impregnated with (occludes therein) a lustering agent,
detergent or other such agent when applied to a wet-type surface
treating device.
[0026] In the embodiment shown in the drawings, the continuously
foamed body 2 is sponge as described above, i.e., a molded soft
body having continuos pores therein. The continuous pores form
spaces for occluding a lustering agent, etc. when the body is
applied to a wet-type surface treating device. The lustering agent,
detergent or other such agent to be occluded includes wax, a
polisher and a cleaner in the state of liquid, solid or emulsion. A
solid agent is first melted into liquid and the liquid is occluded
in the body. In this embodiment, semisolid wax at normal room
temperature is melted at 70.degree. C., and the melt is impregnated
in the body so that it is occluded therein.
[0027] Cloth, nonwoven fabric or other such fibrous member that
permits permeation of the lustering agent etc. occluded in the
continuously foamed body 2 can be used as the fibrous film 3.
However, the fibrous film preferably has high resistance
particularly to friction and tensile strength. In the present
embodiment, cheesecloth (extremely thin, coarse cotton or hemp
cloth) is used as the fibrous film. Various kinds of cheesecloth,
such as of acryl/polyester, acryl/rayon, etc., having various
characteristics, are available on the market. A suitable one can be
selected from among the various kinds.
[0028] The annular engaging member 4 is a member for forcing the
end of the material (2, 3) into an annular groove 53 of the holder
5, that will be described later, and fixing it integrally to the
holder. The part to be forced into the annular groove 53 may be the
end of the fibrous film 3 only. The annular engaging member 4 has a
shape formed by molding plural strips of thin plates annularly,
although the shape is actually determined by the shape and size of
the annular groove 53, that will be described later. To be
specific, the annular engaging member is formed to have a shape and
a size that can prevent the material (fibrous film 3) from coming
out of the annular groove 53. Further, the material of which the
annular engaging member is made is not limited, but is plastic in
this embodiment.
[0029] The annular engaging member 4 in the embodiment shown in the
drawings has an elliptical shape and is provided on the outside
circumferential surface thereof with an engaging portion 41
projecting outward and on the bottom surface thereof with a
plurality of engaging projections 42 that are formed in the shape
of a conical or pyramidal sharp splinter and substantially
equidistantly arranged. The engaging projections 42 bite into the
fibrous film 3 to prevent the fibrous film from coming out of the
annular groove 53 and may therefore be formed in a sawtoothed
shape. Since the annular engaging member 4 is molded to have a
shape and a size that can prevent the material (fibrous film 3)
from coming out of the annular groove 53, as described above, it
does not always require provision of such engaging projections 42.
However, the annular engaging member 4, if provided with the
engaging projections 42, can prevent the fibrous film 3 from coming
out of the annular groove 53 even when it is made thinner. For
these reasons, it is preferable for the annular engaging member to
have the aforementioned shape and size and the engaging projections
so as to make the fibrous film 3 more difficult to come out of the
annular groove 53.
[0030] The holder 5 has a base 51 for supporting the material
(treating portion 11) thereon, the annular groove 53 provided in
the inside peripheral surface thereof with an engaging structure,
and a portion (grip portion 54) to be gripped by a user conducting
a lustering work. While it is an integral molding of plastic in
this embodiment, the material is not limited to plastic.
[0031] In the first embodiment shown in the drawings, the base 51
of the holder 5 is formed to be flat by fitting a lid member 7 for
the base in an open end of the hollow cylindrical grip portion 54,
and the annular groove 53 is formed by bending an outer peripheral
edge 59 of the base 51 inward. The engaging structure formed in the
inside peripheral surface of the annular groove 53 is a convex
portion 52 formed on the upper end of the annular groove 53 so as
to project W inward as is shown in an inset of FIG. 3 that shows
the corresponding part of the figure in an enlarged fashion. The
annular engaging member 4 is attached to the holder by engagement
between the convex portion 52 and the engaging portion 41 formed on
the outer circumference of the annular engaging member 4 so as to
project outward.
[0032] Similarly, the lid member 7 for the base is attached to the
holder by engagement between a convex part 51' formed on the open
end of the grip portion 54 so as to project inward and an engaging
part 71 formed on the outer circumference of the lid member 7 for
the base so as to project outward.
[0033] The cover member 6 comprises a bulged portion 61 and a
fitting portion 62 and is an integral molding of transparent
plastic. The bulged portion 61 covers the treating portion 11
containing a lustering agent to prevent accidental adherence of wax
before the use of the device and volatilization of the lustering
agent. The fitting portion 62 has an inside diameter slightly
smaller than the outside diameter of the outer peripheral edge 59
of the holder 5 surrounding the annular groove 53. The cover member
is retained on the holder 5 by pressure-inserting and fitting the
fitting portion onto the outer peripheral edge.
[0034] The surface treating device 1 in this embodiment is
fabricated by assembling together the material (2, 3), annular
engaging portion 4, holder 5 and cover member 6, each having a
simple structure. This assemblage is conducted very easily.
[0035] To be specific, the treating portion 11 can be supported on
the base 51 and fixed integrally to the holder 5 by causing the
distal end of the annular engaging member 4 to force the end of at
least the fibrous film 3 of the material into the annular groove 53
of the holder 5 and fitting the annular engaging member 4 in the
annular groove 53. The end (folded-back part) of the material (at
least the fibrous film 3) forced into the annular groove 53 is in a
small gap in a state clamped between the side wall surface
surrounding the annular groove 53 and the annular engaging member
4. In addition, the distal ends (engaging projections 42) of the
annular engaging member 4 bite into the material (at least the
fibrous film 3). Thus, the material is prevented from coming out of
the annular groove 53.
[0036] The fitting portion 62 of the cover member 6 is then fitted
on the outer peripheral edge 59 of the base 51 surrounding the
annular groove 53 of the holder 5. Since the inside diameter of the
fitting portion 62 is 0.1 to 0.4 mm smaller than the outside
diameter of the outer peripheral edge 59, pressure insertion of the
fitting portion onto the outer peripheral edge 59 of the holder 5
elastically deforms the cover member and the holder, and the two
are closely fitted to each other by the spread and restoration of
the material of the cover member 6 that compress the outer
peripheral edge of the holder.
[0037] This close fitting produces surface pressure on the contact
surfaces to suppress volatilization loss of the volatile component
in a lustering agent etc. and ensure a long service life of the
device.
[0038] When the surface treating device 1 thus assembled is not in
use, accidental adherence of wax occluded in the treating portion
11 can be prevented by the cover member 6. In operation, by
removing the cover member 6, grasping the grip portion 54 of the
holder 5 and bringing the treating portion 11 against an automobile
body, the treating portion 11 is sandwiched between the car body
and the base 51. The lustering agent occluded in the treating
portion 11 consequently oozes out and is applied thinly onto the
car body surface.
[0039] A layer of natural or synthetic macromolecular particles
having a thickness of approximately 0.5 to 2 mm, though not shown,
can be interposed between the continuously foamed body 2 and the
fibrous film 3 when fabricating the treating portion 11. This layer
of particles is required to have flexibility and elasticity to such
an extent as not to mar the surface to be treated, and is also
required not to react with the lustering agent, not to manifest a
viscous property relative to the surface, and to exhibit a some
degree of motion freedom between the particles and between the
fibrous film and the particles. Examples of usable particles
include micelles of protein, such as leather, synthetic leather and
.beta.-starch; and powders of less viscous rubber,
polytetrafluoroethylene, soft synthetic resin, etc., having a
particle diameter approximately in the range of 5 to 500 .mu.m.
[0040] In this embodiment, since wax semisolid at normal room
temperature is used as the lustering agent, as described above, it
does not flow out. However, since wax contains a volatile
component, it is necessary to prevent volatilization of the
volatile component. If a liquid lustering agent is used, it is
necessary to prevent the outflow thereof. However, since the
fitting portion 62 of the cover member 6 is brought into intimate
contact with and airtightly fitted on the outer peripheral edge 59
of the holder 5 surrounding the annular groove 53, the
aforementioned volatilization and liquid outflow can be
prevented.
[0041] FIGS. 4 to 7 illustrate a second embodiment of the surface
treating device according to the present invention. The elements
identical with or similar to those in the first embodiment are
given the same reference numerals and omitted from the
description.
[0042] While the surface treating device in the first embodiment
has the base 51 fitted integrally to the open end of the grip
portion 54, the surface treating device in the second embodiment
has a base member that is a separate molding from the grip portion
and is fitted to the open end of the grip portion to form a base
for supporting the treating portion thereon.
[0043] Returning to the figures, the base member 8 is provided on
the flat surface thereof with a multiplicity of small protuberances
81 that are arranged substantially equidistantly and bite into the
continuously foamed body 2 when supporting the treating portion 11
thereon, thereby preventing the foamed body from being displaced.
The base member 8 is provided on the peripheral edge thereof with
an overhanging portion 82 projecting outward and downward, inward
of the overhanging portion 82 with a ring wall portion 83 while
leaving a ring groove 84 between the overhanging portion and the
ring wall portion, and on the inside surface thereof with a
plurality of small cylindrical pole portions 85 that are arranged
at predetermined intervals. The base member 8 is made of plastic
similarly to the holder 5.
[0044] The holder 5 is provided on the open end face of the hollow
cylindrical grip portion 54 thereof with a plurality of
protuberances 58 at positions corresponding to the positions of the
small cylindrical pole portions 85 of the base member 8. Each
protuberance has a center hole for admitting the corresponding
small cylindrical pole portion 85 and positioning the base member.
As is shown in an inset in FIG. 7 that shows the corresponding part
of the figure in an enlarged fashion, the holder 5 is further
provided on the open peripheral edge thereof with a pair of
parallel ring walls 55 and 56 between which another ring groove 57
is interposed for fitting the annular engaging member 4
therein.
[0045] The cover member 6 is provided on opposite side surfaces
thereof with a pair of engagement portions 63 and on one side
surface thereof with a projecting portion 64.
[0046] Assemblage of these component members into the surface
treating device 1 of the present embodiment will be described
hereinafter.
[0047] The base member 8 is disposed to face the open end face of
the holder 5. The inside ring wall 55 of the holder 5 is fitted in
the ring groove 84 of the base member 8 and at the same time the
small cylindrical pole portions 85 of the base member 8 are
inserted into the corresponding holes formed in the protuberances
58 of the holder 5. As a result, the base member 8 is positioned on
the open end face of the holder 5 and fixed thereto so as to cover
the holder. The overhanging portion 82 projecting downward at a
position above the ring groove 57 in which the annular engaging
member 4 is fitted, constitutes an engagement structure for the
annular engaging member 4.
[0048] The treating portion 11 is fixed to the holder 5 in the same
manner as in the first embodiment. To be specific, the treating
portion 11 can be supported on the base member 8 and fixed
integrally to the holder 5 by causing the distal end of the annular
engaging member 4 to force the end of at least the fibrous film 3
of the treating portion into the ring groove 57 and fitting the
annular engaging member 4 in the ring groove 57. The annular
engaging member 4 momentarily enlarges in diameter owing to the
presence of a plurality of cuts 43 formed therein as it passes over
the downward projecting overhanging portion 82 of the base member 8
and, upon having passed over the downward projecting overhanging
portion 82 and being fitted in the ring groove 57, restores to its
original diameter.
[0049] As shown in the enlarged inset in FIG. 7, since the end of
the fibrous film 3 forced into the ring groove 57 is clamped
between the side wall of the ring groove 57 and the annular
engaging member 4 and since a swollen portion 44 at the upper outer
periphery of the annular engaging member 4 abuts against the inner
surface of the outside ring wall 56 and is bent inward to cause the
bent end to abut on the downward projecting overhanging portion 82,
the fibrous film is prevented from coming out of the ring groove
57.
[0050] Thus, in the surface treating device according to the
present embodiment the engagement structure can be easily formed by
the annular engaging member 4 at a position above the ring groove
57 by fitting the separate base member on the open end face of the
holder 5.
[0051] The cover member 6 can be airtightly attached to the holder
5 in the same manner as in the first embodiment by
pressure-inserting and fitting the fitting portion 62 of the cover
member 6 onto the outer periphery of the outside ring wall 56
surrounding the ring groove 57 of the holder 5.
[0052] Further, when the airtight attachment of the cover member 6
to the holder 5 is retained for a long period of time, there is a
possibility of the cover member being spontaneously detached from
the holder due to an increase in internal pressure (air pressure
and vapor pressure) caused by changes in the surrounding
temperature and atmospheric pressure etc.
[0053] To avoid this spontaneous detachment, the cover member 6 of
the present embodiment is provided on opposite side surfaces with
the engagement portions 63. When the cover member 6 is
pressure-inserted and fitted onto the holder 5, a concave portion
on the inner peripheral surface of the fitting portion 62 is fitted
on the outside ring wall 56 as shown in the enlarged inset in FIG.
7. In this state, by rotating the engagement portions 63 to cause
the distal end thereof to engage with the holder 5, the cover
member 6 can be firmly fixed to the holder 5. When the internal
pressure in the holder rises, the cover member 6 is
expansion-deformed in the outer peripheral direction by the
pressure to leave a gap between itself and the outside surface of
the holder 5, from which the inside air and the volatile component
of wax etc. are discharged. However, this can be prevented because
the cover member is retained in the firmly fixed state as described
above.
[0054] The firmly fixed cover member 6 can be easily detached from
the holder 5 when using the device by disengaging the pair of
engagement portions 63 of the cover member 6 from the holder and
rotating the grip portion 54 while grasping the grip portion 54 of
the holder 5 using one hand and holding the projecting portion 64
of the cover member 6 using the other hand.
[0055] Although the present invention has been described with
reference to the two embodiments, it is not limited thereto and can
be worked in any way insofar as no alteration is given to the
constitution set forth in the appended claims. Although the
lustering agent applicator has been illustrated as a wet-type
surface treating device by way of example in the embodiment, other
wet-type surface treating devices such as a water-drop adherence
preventing device for automobile windshields, a cleaning
(cleansing) device, an eraser for blackboards, a broad marker pen
(for signboards), etc. can be realized by changing the kind of the
material of the treating portion and changing the kind of liquid
occluded in the material. As a dry-type surface treating device, an
eraser for blackboards can be cited.
INDUSTRIAL APPLICABILITY
[0056] As has been described in the foregoing, the surface treating
device according to the present invention comprises a material
constituting a treating portion, an annular engaging member and a
holder equipped with a base portion, the structures of which are
very simple, resulting in high productivity. In assembling these
component members, adhesive agent, welding operation and other such
means or operation that have heretofore been adopted are not
required. Therefore, no special apparatus or equipment is required,
resulting in safety for operators and high practical utility.
[0057] Furthermore, the wet-type surface treating devices having a
lustering agent, detergent or other such agent occluded in their
treating portion can be advantageously used as disposable ones.
[0058] The surface treating device according to the present
invention can be used as a lustering-agent applicator for car
bodies and tires, furniture, etc., a cleaner (cleanser), an eraser
for blackboards (a blackboard eraser), etc. Thus it has a variety
of applications.
