Description

Brushing tools for cultural properties

The present invention relates to a brush for cleaning cultural properties, in which a movable auxiliary head is used to adjust a substantial length of a bristle so as to prevent unnecessary resource and budget wastage by continuously using the bristle brush without cutting unnecessary brush- , And cultural property cleaning brushes.

In general, Korea is a country with a long history, and cultural assets from the Stone Age have been imported. Among the cultural properties, stone pagodas and stone statues such as Buddhist statues occupy a high proportion of nearly half of all cultural properties.

National National Treasures There are more than 1,000 cultural assets including treasures, including stone artifacts, but they are mostly located outdoors because they are large in size.

In addition, physical and chemical factors such as wind and rain, freezing, melting due to environmental pollution due to acid rain, and biological factors such as moss and microorganisms are seriously deteriorating stone cultural properties.

Most of the cultural assets located in the outdoors are covered with various contaminants, microorganisms such as mosses and bacteria, which not only undermines the appearance of the stone, but also accelerates the destruction. Therefore, it is necessary to clean the stone cultural property for long-term preservation.

[0003] In the technology related to the cleaning of cultural properties, "a device for removing foreign materials from a stone structure and a method for removing the same" (Korean Patent Registration No. 10-1675091, Patent Document 1) A technique of sucking foreign matter from a structure is disclosed.

In addition, the applicant of the present invention has also filed a patent application (Korean Patent Application Laid-Open No. 10-2010-0077231, Patent Document 2) for a method of removing foreign matters on the surface of cultural properties. In Patent Document 2, A technique of round blasting is disclosed.

When high-pressure air injection, water injection, and polishing are applied as in Patent Document 1 or Patent Document 2, brushing using a brush is performed before, during, and after such a process.

Traditionally, brushes used for washing cultural properties have been using commercially available brushes.

The brush which is usually purchased and used has a simulation length of about 3 to 10 cm from the brush head.

However, in the case of such a general brush, since the distance between the head and the end portion is long, a sufficient cleaning effect can not be achieved. Therefore, the workers have deliberately cut out the mock end to use it for cleaning and dispose of it after use.

Therefore, the bristles are cut off and discarded, and the bristles having a shorter brush length are wasted if they become worn so that the bristles become so short as to be difficult to use, resulting in unnecessary waste of resources.

Hereinafter, the brush for cleaning a cultural property of the present invention will be described in detail with reference to the accompanying drawings.

The brush for cleaning cultural properties of the present invention comprises a head 10, a brush bristle 20, an auxiliary head 30 and a driving means 40.

The head 10, which is a component of the present invention, is fixed to one end of the brush bristles 20 and is made of a metal, plastic, wood, or the like, like a normal brush.

Fixation of the brush bristles 20 can be fixed by bonding, insert injection molding, or pressure clamping.

In the example shown in FIG. 1, an arcuate knob 13 connecting both end portions is formed in a flat elliptical plate on which the brush bristles 20 are fixed.

As described above, the brush bristles 20, which are components of the present invention, are fixed to the head 10 at one side and free ends at the other side.

The brush bristles 20 may be fixed to the head 10 in a state where a plurality of brush bristles 20 form a single brush and are separated from each other by a plurality of bristles.

The brush bristles 20 may be made of a hard or soft extruded plastic material such as an ordinary brush, or may be made of animal hair or thread.

The auxiliary head 30 as a component of the present invention is formed with a fitting hole 31 into which the brush bristles 20 are inserted and is connected to the head 10 so that the surface of the head 10 and the bristles 20).

A guide groove 12 is formed in the head 10 to allow movement between the surface of the head 10 and the end of the brush bristles 20, A guide rod 22 inserted into the guide groove 12 is formed at an upper portion of the guide groove 12 so that the surface of the head 10 and the end of the brush bristles 20 As shown in FIG.

At this time, the guide groove 12 and the guide rod 22 may be replaced with a rail and a moving member moving along the rail.

The guide pin 22 is formed of a rack gear engaged with the pinion gear. The guide rod 22 is guided by the guide groove 12 in accordance with the rotation of the pinion gear. Or may be configured to move outwardly.

It is also possible to form a step with a wedge-shaped inner circumferential surface of the guide groove 12, while a protrusion that catches the wedge may be formed at the end of the guide rod 22.

The driving means 40 constituting the constituent element of the present invention allows the auxiliary head 30 to move in both directions toward the head 10 side or the end side of the brush bristles 20 or to be fixed in a moving state.

As an example of the driving means 40 for this purpose, a method of operating by an external power such as a motor or an actuator can be applied.

For example, a space for storing a battery is formed in the head 10, a battery is incorporated in the space, and a circuit for switching the power of the battery to the operation of the motor or the actuator is provided. Or if the electric actuator is connected to the movable member, it is possible to move the auxiliary head 30 as much as necessary through the external power supply.

The two-way motor is connected to the pinion gear, and a circuit and a switch for controlling the operation of the motor are installed outside the head 10 to stop and operate the motor and change the rotation direction The auxiliary head 30 can be driven.

However, in the case of such an external power system, the manufacturing unit price is increased, and the possibility of failure due to moisture is increased.

Therefore, it is preferable to use a manual method instead of an external power.

1 to 3 show an example of simple but easy to operate.

In the illustrated example, the head 10 is provided with a bolt insertion hole 11 having a thread on the inner circumferential surface formed on the bottom surface thereof. The auxiliary head 30 is provided with a bolt insertion hole 11, Preventing groove 32 having an inner diameter larger than that of the surface layer.

The driving means 40 further includes a body portion 41 having a screw thread formed on an outer circumferential surface thereof and inserted and screwed into the bolt insertion hole 11 and a lower portion formed on the lower portion of the body portion 41, And a grip portion 43 connected to the upper portion of the body portion 41 to rotate the body portion 41. [

In this configuration, the driving means 40 takes the form of a bolt with a handle, and the end is not directly connected to the auxiliary head 30 but is installed in a freely rotatable structure within the departure prevention groove 32, So that the rotary motion of the auxiliary head 40 is provided in the linear motion of the auxiliary head 30. [

At this time, it is preferable that a bearing 32a is provided between the inner circumferential surface of the separation preventing groove 32 and the outer circumferential surface of the enlarged diameter portion 42 to minimize unnecessary rotation of the auxiliary head 30.

1, when the user holds the handle 43 and rotates, the body 41, which is screwed with the bolt insertion hole 11, is rotated and inserted into the guide groove 12 inserted into the guide groove 12 The auxiliary head 30 is spaced apart from the head 10. As a result,

At this time, the enlarged diameter portion 42 on the end side of the body portion 41 is spaced apart from the release preventing groove 32 so as to be freely rotatable, or is supported by the bearing 32a and freely rotated.

The auxiliary head 30 is not rotated by the rotation of the body portion 41 by the guide bar 22 inserted in the guide groove 12 but is simply moved away from the head 10. [

In this case, since the intermediate portion of the brush bristles 20 is inserted into the auxiliary head 30 to prevent the brush bristles 20 from being separated from the brush bristles 20, it is possible to improve the cleaning efficiency by increasing the frictional strength.

On the other hand, Fig. 8 shows another embodiment of the driving means 40. Fig.

In the embodiment of the drawing, a bolt receiving hole 14 is formed in the head 10, and a bolt separation preventing portion 15 protruding toward the center of the bolt receiving hole 14 is formed on the bolt receiving hole 14 And a lower step portion 16 projecting toward the center of the bolt receiving hole 14 is formed in the lower portion of the bolt receiving hole 14.

The auxiliary head 30 is provided with an upper projection 35 inserted into the bolt receiving hole 14. A bolt fastening hole 36 formed in the inner peripheral surface of the upper projection 35, The upper end of the upper protrusion 35 protrudes outward so that the outer diameter of the upper protrusion 35 is larger than the inner diameter of the lower end protrusion 16, A portion 37 is formed.

The driving means 40 includes a bolt body portion 44 screwed to the bolt fastening hole 36 to move the upper protruding portion 35 up and down and a bolt body portion 44 formed on the bolt body portion 44, A movement preventing groove 45 for preventing upward and downward movement of the bolt body portion 44 by inserting the bolt departure preventing portion 15 inwardly; And a handle 46 for rotating the handle 44.

This embodiment is advantageous in that the grip portion 46 is prevented from being vertically moved compared with the embodiment of FIG. 1, so that interference between the grip 13 and the grip 13 is prevented, and unnecessary bearings are not required to be installed. .

8 is a state in which the auxiliary head 30 is in close proximity to the head 10 and the lower part of FIG. 8 is the upper part of the upper projection 35 without moving up and down as the knob part 46 is turned. The upper projection 35 is moved downward by the screwing of the bolt body 44 and the auxiliary head 30 coupled with the upper projection 35 is moved downward as it is.
Since the guide groove 12 is formed in the head 10 as described above and the guide bar 22 inserted into the guide groove 12 is formed in the upper portion of the auxiliary head 30, The auxiliary head 30 is moved upward and downward without rotating horizontally as the portion 46 is rotated.

7, the height of the enlarged diameter portion 42 is not formed so as to fit tightly at the depth of the separation preventing groove 32 but is formed to be smaller than the depth of the separation preventing groove 32 so as to be spaced apart with a margin, An example in which a spring mounting groove 42a is provided on the bottom side and a spring 42b is provided in the spring mounting groove 42a is shown.

In this case, the inner diameter of the guide groove 12 is made larger than the outer diameter of the guide rod 22 so that the guide rod 22 can flow in the guide groove 12 in the horizontal direction.

This arrangement allows the auxiliary head 30 to flow in the horizontal direction. This is because the auxiliary head 30 can be moved in the horizontal direction by the flow of the auxiliary head 30 in accordance with the direction in which the force is applied, The length of the brush bristles 20 protruding from the surface of the brush bristles 30 can be adjusted to enable fine brushing.

Although the middle portion of the bristles 20 is fitted in the fitting hole 31 to suppress the deformation of the brush bristles 20 in the above-described configuration, when the bristles 20 are very long or soft like a brush, It may be bent while being pressed against the object to be cleaned, and the portion located in the space between the auxiliary head 30 and the head 10 may be largely deformed or eventually deviated from the fitting hole 31 to lose the brushing ability.

As shown in FIG. 4, the fitting hole 31 may have a tapered cross-sectional shape in which the inner diameter gradually decreases toward the end of the bristles 20, as shown in FIG.

In this case, the bristles 20 are pressed firmly on the lower side of the fitting hole 31 where the inner diameter is reduced to prevent excessive deformation and dislocation, thereby providing a feeling of using a brush having a substantially short length, Can be provided.

In order to move the auxiliary head 30 away from the head 10 and to move the auxiliary head 30 in the opposite direction, it is necessary to increase the torsional angle of the bristles 20, 20) surface and the inner circumferential surface friction of the fitting hole 31 become large and damage such as breakage of the brush bristles 20 may occur.

That is, there is a limit in the taper angle of the wall surface of the fitting hole 31, and an example of the configuration that can overcome such a problem is shown in FIGS.

A brush pressing member 50 is connected to the bottom surface of the auxiliary head 30 such that the brush pressing member 50 is movable in one direction and the brush pressing member 50 is moved An auxiliary fitting hole 51 is formed at a specific point on the path so as to be in line with the fitting hole 31. The brush pressing member 50 is formed in a state in which the fitting hole 31 and the auxiliary fitting hole 51 are displaced, And a fixing means 60 for fixing the light emitting diode 10 to the auxiliary head 30 are provided.

5, the auxiliary head 30 is formed with a rail groove 33 having a wide inner width on the surface opposite to the side facing the head 10,

The brush pressing member 50 is provided with a moving member 52 on the surface facing the auxiliary head 30 so as to be movable along the rail groove 33.

Therefore, as the moving member 52 moves, the brush pressing member 50 is prevented from being separated from the auxiliary head 30, and can be moved to either side.

The moving member 52 and the rail groove 33 may be installed in the same direction among the contact surfaces of the brush pressing member 50 and the auxiliary head 30, and the length of the rail groove 33 is less than 1 cm , More specifically, less than half of the diameter of a group of brush bristles 20 may suffice.

5, the fixing means 60 includes two support rods 34 protruding from the surface of the auxiliary head 30, and two support rods 34 which are provided on the end sides of the brush pressing member 50 and have sharp ends And two hook needles 53 having barbs formed on the end side like a fishing needle.

In this configuration, when the user releases the pressing force in a state in which the two pressing needles 53 are moved toward the side of the supporting rod 34 while slightly pressing the brush pressing member 50 in the direction opposite to each other, The barb portion of the barb 34 is caught by the support bar 34 and restrained from moving in the opposite direction.

At this time, it is preferable that the fitting hole 31 and the auxiliary fitting hole 51 are slightly shifted and the brush bristles 20 are pressed when the engaging needle 53 is caught by the supporting rod 34 .

In addition, the illustrated fastening means 60 is merely an example, and is not limited to the above description, and various known fastening means such as a clamping system, a magnet system and the like can be applied.

Fig. 6 shows an operating state according to this configuration.

As shown in the drawing, as long as the brush pressing member 50, in which the auxiliary fitting hole 51 is disposed, is moved only in the unit of mm in a certain direction in the same manner as the fitting holes 31, the bristles 20 are firmly held You can see that the role is to play a role.

In this way, the brush pressing member 50 can be easily moved to the other side, so that the brush bristle 20 can be selectively pressurized or the pressing operation can be released, so that the auxiliary head 30 can be moved in both directions freely, 20) is selectively made.

The brush for cleaning cultural properties according to the present invention can be applied to various washing fields other than cultural properties, but it can exert the optimum effect when used for washing various historical and cultural properties.
