Description

  The present invention relates to a cleaning brush that can easily and reliably clean a keyboard of a personal computer or a word processor.

Conventionally, as a device for cleaning a keyboard of a personal computer or a word processor, for example, a cleaning device for office equipment shown in Patent Document 1 is known.
The outline of this device is that a keyboard to be cleaned is installed in a keyboard holding frame of a cleaning device, and a brush provided toward the keyboard is provided on a brush mount that reciprocates toward the front of the keyboard holding frame, The entire keyboard is cleaned by vibrating the brush tip using a vibration device connected to the brush mount via a leaf spring.

  In such a known keyboard cleaning device, not only the device itself is large, but also the keyboard itself needs to be mounted on the keyboard holding frame of the cleaning device in order to clean the keyboard. There has been a drawback that the word processor keyboard cannot be constantly cleaned in its use state.

On the other hand, when a known example of the cleaning brush itself is seen, for example, as shown in Patent Document 2, a cleaning brush is known in which the hair tip shape is processed in accordance with the shape of an object to be cleaned.
However, the cleaning brush described in the publicly known document specifically cleans the rail groove of the aluminum sash frame provided in the opening of the building, and a large number of brush bristles implanted in the base plate portion are The tip position is aligned by providing steps in a plurality of stages.

  In addition, although a large number of brush bristles arranged with steps are arranged on one base plate portion, the handle integrated with the base plate portion has a rod shape similar to that of a normal brush. Body or by a loop-shaped handle for constructing a hook hole. And each end of the brush hair cut and arranged in a plurality of stages is adapted to the width of the rail groove to be cleaned, and moves and cleans with the handle of the brush along the rail groove. To do.

For this reason, when moving along the rail groove to be cleaned with the handle of the brush, the angle between the handle and the wrist tends to change, and it is quite difficult to move it parallel to the rail.
Naturally, it is difficult to effectively clean, for example, the grooves between the keys of the keyboard with such a brush in which a large number of brush tips are trimmed.

The present invention provides a cleaning brush for sweeping out dust or the like accumulated in a groove portion between keys in a keyboard of a personal computer or a word processor as described above.
Here, when looking at the structure of a keyboard of a personal computer or word processor, the size of each key is a square of about 19 mm × 19 mm, and a large number of such keys are generally arranged in upper and lower six stages. Between each of these stage rows, a laterally elongated lateral groove is formed.

On the other hand, a large number of keys arranged in the upper and lower rows are arranged so as to be shifted from each other by approximately half the width dimension for each row in the left-right direction. The upper and lower tiers are formed so as to be shifted by a dimension close to about half of the key width.
As a result, it is natural that it is difficult to clean the vertical and horizontal narrow groove bottoms of the upper and lower keyboards with a brush in which a large number of brush bristles, which are normal brushes, are aligned to be flush with each other. As described in Patent Document 2, it is not easy to clean the groove bottom of the keyboard even with a brush in which the length of the brush bristles is cut and aligned in multiple stages.

  In view of the above circumstances, the present invention is formed in a plurality of vertical and horizontal horizontal grooves formed by a number of keys arranged in a plurality of stages and shifted horizontally in each stage, and each stage is formed alternately. The present invention provides a cleaning brush suitable for cleaning a personal computer and a word processor keyboard having a large number of vertical grooves in the vertical direction.

  Furthermore, by making the structure of the brush frame and the planting position of the brush bristle appropriate, it is possible to efficiently clean a plurality of horizontal narrow groove bottoms in a straight line, and the vertical narrow groove bottoms arranged alternately in the vertical direction, It is an object of the present invention to provide a brush capable of efficiently sweeping dust in the vertical groove into the horizontal groove while the same brush is rotated by 90 °.

The present invention is a keyboard cleaning brush comprising a brush frame body and a large number of hair bundles, and the brush frame body has a flocking pedestal part at the center and a pair of clamping parts integrally formed with the flocking pedestal part. It has a substantially U-shaped cross section, and a plurality of hair bundle rows are formed on the surface of the flocked pedestal, and the plurality of hair bundle rows are formed at an interval of about 20 mm from each other. Each of which is composed of seven hair bundles planted at equal intervals, and a plurality of convex strips are formed on the outer surface of the pair of sandwiching portions in a substantially vertical direction. This is a keyboard cleaning brush.
In addition, a large number of hair bundle rows on the surface of the flocked pedestal can be provided with three hair bundles on the left and right sides with an interval of about 10 mm between them.
Furthermore, in addition to the above-mentioned hair bundle on the upper surface side, a keyboard cleaning brush having three rows of hair bundles on the lower surface and four rows of hairs can be provided.

According to the keyboard cleaning brush of the present invention, since the flocking pedestal portion of the brush frame and the pair of sandwiching portions are integrated, and a large number of protruding strips are provided on the surface of the sandwiching portion, the linear operability of the brush is improved. did.
A plurality of rows of hair bundles are provided on the vegetation pedestal, and the intervals between the rows of hair bundles and the intervals between the narrow grooves between the keys are matched, so that a large number of narrow grooves between the keys can be cleaned at the same time. On the other hand, if five rows of brushes are used, the cleaning can be completed by one horizontal cleaning.
In addition, by providing a gap of about 10 mm in the middle portion of each hair bundle row, the degree of entry of the hair bundle ends into the grooves was improved in the longitudinal groove cleaning by the end hair bundle ends of each hair bundle row.
Furthermore, by providing the lower surface side hair bundle row exclusively for the longitudinal groove, the insertion of the end of the hair bundle into the longitudinal groove is deepened, and the cleaning efficiency in the longitudinal groove is improved.
Furthermore, by setting each hair bundle row of the present invention to a length of about 25 mm, each hair bundle row is better accommodated in the groove when the transverse groove is cleaned, and in combination with the flexibility of the appropriate hair bundle, The cleaning movement speed could be increased.

An embodiment of the present invention will be described with reference to FIGS.

A keyboard cleaning brush 1 shown as a perspective view in FIG. 1 includes a brush frame 2 and a large number of hair bundles A. The brush frame 2 includes a flocking pedestal 3 and sandwiching portions 4 and 4 integrally formed on both sides of the flocking pedestal.

In order to plant a large number of hair bundles, a large number of hair bundle holes 5 to 5 are formed on the surface of the flocked base 3. In the keyboard cleaning brush 1 according to this embodiment, the total number of the hair bundle holes 5 to 5 is 119 in a total of 17 vertically and 7 horizontally. The distance d between the bristles 5 and 5 is approximately 5 mm, the inner diameter of each bunch is about 2 mm, and the drilling depth is 2 to 3 mm.
In addition, the arrangement and size of these hair bundle holes are not special.

  The sandwiching portions 4, 4 provided integrally with the flocked pedestal portion 3 on both sides of the brush frame body 2 are provided with a number of fine ridges 6-6 on the surface thereof, and the size and spacing thereof. However, when the brush 1 is clamped with one hand by these many ridges, the ridges lightly bite into the finger surface to play a role of anti-slip. Further, as described above, by providing a large number of ridges 6 to 6 on the surfaces of both the sandwiching portions, it becomes easy to accurately move the hair bundle row described later along the inter-key groove.

  As shown in FIG. 1, the hair bundles A are planted in three rows at equal intervals in the longitudinal direction between the plurality of hair bundle holes 5 and 5 and in the middle thereof. Therefore, in this embodiment, referring to FIG. 1 and FIG. 2, seven hair bundles A to A are implanted in one row at the leftmost end, and then three rows of hair bundles that are not implanted. A hole row exists and is formed so that the next second hair bundle row exists. Eventually, a total of five hair bundle rows are provided.

Each of the hair bundles A to A is configured as a bundle of many synthetic resin fine hairs having a diameter of about 0.3 mm, and the diameter of the hair bundle is about 2 mm. Moreover, the protrusion length from the flocked base part surface of the said hair | bristle bundle A is about 25 mm.
As can be seen from FIG. 2, the hair bundles arranged in this way have a width f between the hair bundles of about 20 mm, and the vertical and horizontal thin lines between the keyboard rows defined on a side of 19 mm. It is approximately the same as the groove interval.

3 and 4 are a front view and a bottom view of the keyboard cleaning brush 1 according to the first embodiment shown in FIG.
As is clear from FIG. 3, the width F of the flocked pedestal 3 of the brush frame 2 is about 40 mm, and the height H of the pair of clamping parts 4, 4 is about 20 mm. Is formed in a substantially U-shaped cross-section so that the lower part thereof is slightly expanded.

Respectively.
However, in actuality, all the hair bundle holes are drilled up to the middle of the flocked pedestal 3, and only the positions of the hair bundle holes are shown. Moreover, the full length L of the brush frame 2 is about 90-100 mm.

5 to 8 show a keyboard cleaning brush 1 according to a second embodiment of the present invention.
Referring to the perspective view of FIG. 5 showing the front side of the keyboard cleaning brush 1, all the thicknesses, lengths, and hair bundle numbers of the hair bundle A are the same as those in the first embodiment shown in FIG. The structure is the same.
However, in the keyboard cleaning brush 1 according to this embodiment, the height H of the pair of sandwiching portions 4A and 4A in the brush frame 2 is set to about 10 mm.

As is apparent from FIGS. 6 to 8, the keyboard cleaning brush 1 according to this embodiment has another lower flocking pedestal 7 integrally formed on the back surface of the flocking pedestal 3.
The lower flocked pedestal 7 is also provided with a number of hair bundle holes 5 to 5 similar to the case of the flocked pedestal portion 3, and a plurality of hair bundles A similar to the above are implanted.
However, as is apparent from the drawing, the lower flocking pedestal 7 is provided with three hair bundles A in the horizontal direction and four rows in the vertical direction. Then, there are three rows of non-planted hair bundle hole rows between each of the hair bundle rows. Therefore, the interval f between the hair bundle rows is about 20 mm as shown in FIG. Of course, it is about 5 mm as in the case of the upper flocked pedestal 3.

  In the keyboard cleaning brush 1 configured as described above, the lateral narrow groove of the keyboard is exclusively cleaned by, for example, the upper hair bundle A group in FIG. In addition, it is convenient to clean the vertical narrow grooves of the keyboard exclusively by the upper and lower three-row and four-row hair bundle groups shown in FIG. These actions will be described in detail separately.

The keyboard cleaning brush 1 according to the third embodiment of the present invention is described in detail in FIGS.
FIG. 9 is a perspective view of the keyboard cleaning brush 1 according to this embodiment, which is substantially the same as that of FIG. However, each hair bundle row of the brush 1 according to this embodiment is composed of six hair bundles A by omitting intermediate hair bundles in each hair bundle row, as is apparent from the drawing.

This state is particularly well represented in FIG. 10 and FIG. 12, for example, from the keyboard cleaning brush 1 having the structure shown in FIGS. The structure is removed.
Therefore, in particular, in FIG. 10, a gap having an interval l of about 10 mm is generated between the inner ends of the three hair bundles on the left side and the three hair bundles on the right side. And since the structure of other parts is the same as that of the keyboard cleaning brush according to the first embodiment shown in FIGS. 1 to 4, a detailed description relating to the drawings is omitted.

To do. At this time, a large number of ridges provided on the surfaces of the clamping parts 4 and 4 lightly bite the surface of each finger, and the clamping is stabilized, and at the same time, the brush that is clamped and moved by the thumb and the other four fingers The directionality of the main body is stable.

  Next, the longitudinal direction of the keyboard cleaning brush 1 is turned sideways, and the hair bundles corresponding to the uppermost part or the lowermost part of the five hair bundles are arranged between any board row of the keyboard and between the boards. The brush frame 2 is tilted either up or down at a position where it is fitted between the vertical narrow grooves, and abuts against the keyboard surface.

  In this case, since the side surface of each key in the keyboard is provided with an inclined surface, if the keyboard cleaning brush 1 as a whole is tilted up and down and moved slightly to the left or right, each of the keys facing in the vertical direction Since the hair bundle tip of the hair bundle row contacts the inclined side surface of the key, by moving the brush down in this state, the end hair bundle end of the hair bundle row can be easily moved from any of the above to the vertical narrow groove between the keys. It can be fitted in.

  As a result, the upper end portion or the lower end portion of each hair bundle row is fitted into the inter-key vertical narrow groove that is the width of the corresponding hair bundle, so in the brush according to the first embodiment In this state, by moving the entire keyboard cleaning brush 1 up and down slightly, all the dust in the corresponding vertical narrow groove can be moved and removed in either the upper or lower horizontal narrow groove. By performing such an operation on the entire surface of the keyboard, dust in all the vertical narrow grooves can be transferred into the upper and lower horizontal narrow grooves.

  In the brush according to the third embodiment, the entire keyboard cleaning brush 1 is moved diagonally from the upper end of the keyboard to the left or right side along the vertical groove to the lower end of the keyboard. Dust can be swept out. In this case, the brush according to the present embodiment can clean the vertical grooves only by moving diagonally in one direction by providing an interval of 10 mm in the middle of every three hair bundles. Further, by setting the length of the hair bundle to 25 mm, it is possible to reach the lower part of the vertical narrow groove and easily sweep out dust.

Subsequently, the keyboard cleaning brush 1 is directed in the vertical direction, and each hair bundle row is fitted into the lateral narrow groove of the keyboard in the same manner as described above. Then, the dust collected in the horizontal narrow grooves can be discharged to the keyboard end side by moving the brush left or right along the horizontal narrow grooves or reciprocating the brush.
In this case, the sandwiching portions 4 and 4 are sandwiched between the thumb of one hand and the other four fingers, so that the action of the multiple thin ridges 6 to 6 provided in the sandwiching portions 4 and 4 is achieved. In combination with this, it becomes possible to move the brush right and left in character.

Next, a method for using the keyboard cleaning brush according to the second embodiment will be described.
First, in the state shown in FIGS. 7 and 8, the pair of left and right clamping parts 4, 4 are clamped by the thumb and other four fingers as much as possible. And in order to make the hair | bristle bundle A-A of the lower side of a figure fit in the vertical groove of a keyboard, the longitudinal direction of the said brush is hold | maintained sideways.

  Subsequently, as described in [0026] above, the tips of the three hair bundles in any of the hair bundle rows are lowered so as to be fitted into the vertical grooves between any of the keys. In this case, if the entire keyboard cleaning brush is lowered while moving slightly to the left or right, and the tip of the hair bundle touches the inclined surface of one of the keys, this inclined surface can be used as a guide to easily handle all the vertical narrow grooves. A hair bundle row can be inserted into the inside.

Next, by moving the entire keyboard cleaning brush 1 from the upper end of the keyboard diagonally to the left or right along the vertical groove to the lower end of the keyboard, dust in the vertical groove can be swept out. In this case, since the lower side hair | bristle bundle of the brush 1 for keyboard cleaning which concerns on this embodiment is comprised by all 3 and the width | variety is 12 mm and each row | line | column is a space | interval of 20 mm, it is diagonally inclined to one direction. The vertical groove can be cleaned simply by moving.
Further, by setting the length of the hair bundle to 25 mm, it is possible to reach the lower part of the vertical narrow groove and easily sweep out dust.

  Thereafter, as in the above [0030], the keyboard cleaning brush 1 is turned upside down, and five rows of hair bundles, each consisting of seven hair bundles, are fitted into the lateral narrow grooves of the keyboard, and dust is discharged to the left and right. Thus, the inside of the narrow groove between the vertical and horizontal keys in the keyboard can be cleaned with an extremely simple operation.
