Description

The present invention relates to a gap brush for closing a gap between a building and a shutter, a door, and the like that can be used for opening and closing a building opening, for example.

To smoothly open and close between opening and closing members such as shutters and doors used for opening and closing the building opening in a building opening provided on the wall and the like for passing through the inside and outside of the building The gap is provided. Conventionally, various proposals have been made for gap brushes that close the gap (for example, Patent Documents 1 to 3).

These brushes are a combination of a brush body in which hair bundles are gathered and an attachment member for fixing the brush body to the building side. The attachment member is fixed to the building, and the tip side of the brush body is It arrange | positions and is used so that the said opening-and-closing member may be touched. Hereinafter, the form of the gap brush when attached to the attachment place and filling the gap around the attachment place is referred to as a passage suppression form.

The clearance brush can open and close the building opening in this passage suppression mode, and can close the clearance with a brush, thereby suppressing the passage of foreign matter in the front-rear direction of the brush. As a result, it is possible to prevent the invasion of various foreign matters such as organisms such as insects, dust, dust, harmful substances and the like.

Patent Document 3 proposes a gap brush that can increase the degree of sealing by closing the gap between the hair bundles and the gap between the hair bundles at the proximal end of the hair bundle.
At the same time, in Patent Document 3, the inclination angle of the brush body is adjusted and attached, and in the passage suppression mode after the attachment is completed, the angle adjustment function that can be used while the attached inclination angle is reliably maintained. We have proposed a brush for gaps that has been added.

However, although the gap brush can open and close the building opening in a passage-restricted form, for example, there are problems such as an increase in resistance when the shutter is opened and a large noise is generated. There is a case.
In particular, the shutter is connected to a large number of horizontally long plate-like bodies called slats, and is opened and closed by winding up and rewinding a large number of slats. At the time of opening and closing, the slat moves up and down while bending back and forth. Further, the vertical cross section of the slat is generally curved, and the shutter has a shape in which peaks and valleys repeat even in a stationary state.

On the other hand, since the clearance brush is fixed at a fixed angle with respect to the shutter in the passage suppression mode, depending on the movement at the time of opening and closing the shutter, there is a case where resistance increases or a large noise occurs. There is.

Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. It should be noted that the expressions of the top, bottom, front, back, left and right in the claims and the description of the present application only indicate a relative positional relationship, and do not specify an absolute position.
As shown in FIG. 1, the gap brush according to the first embodiment of the present invention includes a brush body 11 and an attachment member 20.

(About the brush body 11)
As shown in FIG. 2, the brush body 11 includes a plurality of hair bundles 12 and a brush base portion 14. The hair bundle 12 is an aggregate of a plurality of brush hairs 13, and the plurality of brush hairs 13 form a group of hairs according to a standard method to constitute the hair bundle 12, and are planted on a brush base portion 14 made of synthetic resin. Yes.

The brush base 14 has a left-right direction as a longitudinal direction, and a plurality of hair bundles 12 are arranged in the left-right direction of the brush base 14. Accordingly, the brush body 11 has a large number of brush bristles 13 arranged in the left-right direction along the longitudinal direction of the brush base 14 continuously extending in the left-right direction.

In this example, the hair bundle 12 is arranged in two rows on the front and back, but may be one row or three or more rows.
In the following description, unless otherwise specified, the longitudinal direction of the brush base portion 14 is defined as the left-right direction and the short direction is defined as the front-rear direction, regardless of the attachment position.

The bristle bundle 12 is a collection of a large number of brush bristles 13 formed of plastic wire that can be elastically deformed according to the unevenness of the shutter, forward / backward movement and deflection in the above-described passage restraint mode. It is. When the bristle 13 is made of a synthetic resin, a thermoplastic resin (PE / PP / PBT / PA) is suitable. However, the material of the brush hair 13 may be made of a synthetic resin other than the above as long as it has appropriate elasticity, durability, and weather resistance, and can be formed using other materials such as animal hair. is there.

Specifically, when a polypropylene (PP) resin is used for the brush hair 13 as a measure for small animals such as mice, the diameter is preferably 0.7 to 1.0 mm. Moreover, it is preferable to use a thing with a diameter of 0.1-0.5 mm as a thing for insect measures. However, the present invention can be applied regardless of the object, whether for insects or small animals, and can be selected in various diameters. . Moreover, said diameter can be suitably changed and implemented according to the raw material, length, etc. of the bristle 13. Moreover, you may make it mix | blend the repellent with respect to the animal etc. in the raw material of the bristle 13.

The brush base 14 is made of a hard plastic such as a copolymer synthetic resin (ABS resin or the like) that is not easily elastically deformed compared to the brush bristles 13 or a metal or wooden member, and extends continuously in the left-right direction. The cross-sectional shape is a trapezoidal shape that is tapered from the proximal end side toward the distal end side. However, the cross-sectional shape of the brush base portion 14 is not limited to this, and may be a rectangular shape or a shape having a curved surface.

The base ends of the respective hair bundles 12 are planted so as to penetrate the brush base portion 14 vertically and project upward from the upper surface of the brush base portion 14. In the example of FIG. 2, two rows of hair bundles 12 are arranged on the brush base portion 14 in the front-rear direction, and one row and the other row of the hair bundle 12 are staggered. Thereby, the space | gap between the hair | bristle bundles 12 can be made small compared with arranging the hair | bristle bundle 12 in two rows and the same position in the front-back direction. Moreover, as shown in FIG. 2 (C), even when connecting a plurality of brushes in the longitudinal direction, if the end 15 of the brush base 14 is cut obliquely, It becomes easy to arrange the hair bundle 12 at equal intervals as in the other portions.
As shown in FIGS. 3 and 6, the length of the bristle 13 of the bristle bundle 12 is set so that it can contact an object such as the slat 51 when the gap brush is attached. The surface of the slat 51 has uneven undulations, but it is preferable that the slat 51 has a length that can contact any part of the undulations.

(About the mounting member 20)
As shown in FIG. 1, the attachment member 20 includes a holder 21, an intermediate part 31, and a fixing part 41. The holder 21 holds the brush base portion 14, the fixing portion 41 is fixed to the attachment location 50 by fixing means such as a screw, and the intermediate portion 31 is disposed between the fixing portion 41 and the holder 21. It is what is done. Therefore, the attachment member 20 includes a fixed portion 41 fixed to the attachment location 50 and an intermediate portion 31 interposed between the fixed portion 41 and the brush base portion 14. The intermediate portion 31 is interposed between the fixing portion 41 and the holder 21 (and thus the brush base portion 14) so that the brush main body 11 can move in the front-rear direction in a passage restraining form.

(About holder 21)
In this embodiment, the holder 21 includes a base portion 22 that extends in the left-right direction, and a side wall portion 23 that extends from the front and rear of the base portion 22 in the direction of the distal end (side closer to the brush bristles 13). The front and rear side wall portions 23 sandwich the brush body 11 therebetween, and in this example, the holding portion 24 is provided at the base end (side closer to the fixing portion 41), and the concealing portion 25 is provided at the distal end side.

The side wall 23 holds the brush base 14 by passing the brush base 14 between them. When assembling, one end in the longitudinal direction (left-right direction) of the brush base portion 14 may be inserted from one end in the longitudinal direction (left-right direction) of the holding portion 24. If the brush bristles 13 are worn out and need to be replaced, the brush bristles 13 can be removed and replaced easily.

The concealment portion 25 reaches the base of the hair bundle 12 and conceals a small gap generated between the bases of the hair bundle 12, thereby preventing a small insect or the like from entering the small gap between the hair bundles 12. Dust can be eliminated. In particular, it is also preferable that the distance between the front and rear concealment portions 25 be smaller than the front and rear width of the group of brush bodies 11 including the group of hair bundles 12 in a free state (state before mounting). Thereby, in the state which mounted | wore the brush main body 11 with the holder 21, the base part of the bristle bundle 12 spreads in the horizontal direction, and the advantage which can suppress generation | occurrence | production of a small clearance more effectively arises. However, this point is not indispensable, and the interval between the front and rear concealing portions 25 may be set to be equal to or larger than the front and rear width of the group of brush bodies 11 including the hair bundles 12 group in a free state (a state before mounting). Alternatively, it may be carried out without providing the concealing portion 25. Furthermore, if the replacement of the brush body 11 is not taken into consideration, the intermediate part 31 may be directly fixed to the brush base part 14 without using the holder 21.

(About the fixing part 41)
The fixing portion 41 includes a connection portion 42 where the intermediate portion 31 is provided, and a fixing portion 43 that fixes the connection portion 42 to the attachment location 50. In the gap brush in the example of FIG. 1, the connection portion 42 and the fixed portion 43 are orthogonal to each other. This gap brush is for lintels, and as shown in FIG. 3, a substantially horizontal cross member or a casing of a shutter that is disposed immediately above the opening of the building is attached to this as a mounting location 50. It is done.

In the example of FIG. 3, the shutter is attached to a general shutter, and a plurality of strip-like slats 51 are connected in the vertical direction. The gap brush is attached so that the tip of the brush bristles abuts substantially vertically on the slat 51 in a state where the opening of the building is closed. The brush body 11 can be attached to both the inside and the outside of the shutter, but from the viewpoint of preventing intrusion from the outside, as shown in FIG. 3, it is arranged on the outside (left side in the figure). Is appropriate.

Although not shown in the drawings, the fixed portion 43 includes screw insertion holes with appropriate intervals in the left-right direction. The fixed portion 43 is overlaid on the attachment location 50 and is fixed to the attachment location 50 with a tapping screw or the like passed through the screw insertion hole. This fixing may be other fixing means such as adhesion or double-sided tape other than screws, or detachable fixing by fitting or engagement.

In this example, the connection portion 42 is formed at a right angle to the fixed portion 43. The connection portion 42 is a member that is integral with the fixed portion 43, but the connection portion 42 and the fixed portion 43 may be connected directly or indirectly to separate members.
Further, in this example, one end of the cover 44 is provided at one end of the fixed portion 43 so as to be rotatable via front and rear hinges 45. The other end of the cover 44 can be attached to and detached from the connection portion 42. After the cover 44 is rotated and opened to perform the screwing, the cover 44 is rotated and closed in the reverse direction to close the connection portion 42. Engage with. Thereby, it is possible to prevent the screw from being seen from the outside, improve the design, and prevent dust and the like from being attached. The holder 21 and the fixing portion 41 are made of a material that is hard to elastically deform, such as a hard synthetic resin such as hard polyvinyl chloride or ABS resin, or a metal.

(About the middle part)
The connection portion 42 and the base portion 22 are connected via the intermediate portion 31. The intermediate portion 31 is made of an elastically deformable material such as soft polyvinyl chloride or low density polyethylene (LDPE). The intermediate part 31 only needs to be elastic enough to be elastically deformed when the distance between the shutter and the fixed part 41 changes due to the forward / backward movement or bending of the shutter. As a result, when the distance between the shutter and the fixed portion 41 changes due to forward / backward movement or deflection of the shutter, the intermediate portion 31 elastically deforms together with the bristles 13 to absorb the change in the distance, and the shutter It is possible to alleviate the resistance applied to and to prevent the generation of loud sounds. Moreover, in the free state where there is no longer any contact with the brush hair, the original state is restored.

In this example, the intermediate portion 31 is formed as a single plate-like body extending in the left-right direction, and is configured to be elastically deformed in the thickness direction of the plate-like body. Thereby, the brush main body 11 can move in the front-rear direction with respect to the fixed portion 41 in a passage suppression mode. The intermediate portion 31 may be flat, but is curved in the middle in the width direction. Then, as shown in FIGS. 1 and 3, the intermediate portion 31 is attached to the attachment portion 50 so that the middle in the width direction projects downward. Thereby, the intermediate part 31 can be easily elastically deformed in the front-rear direction. More specifically, the upper side (inner side) in FIG. 1 draws an arc having a smaller radius than the lower side (outer side) . However, the intermediate part 31 may be configured such that the lower side draws an arc with a smaller radius than the upper side, and the upper and lower sides have the same radius and the whole is curved. Further, the middle thickness in the width direction may be larger than both ends, and conversely, the middle thickness in the width direction may be smaller than both ends.

Further, as described above, it is advantageous to connect the holder 21 and the fixing portion 41 by one intermediate portion 31 in terms of the resistance reduction and the suppression effect of the generation of sound, but as shown in FIG. Even when a plurality of intermediate portions 31 are provided at the front and rear, the resistance can be lowered as compared with the case where the holder 21 and the fixing portion 41 are directly connected without the intermediate portion 31 being interposed.

In addition, a spring material such as a coil spring can be used in place of the elastically deformable intermediate portion 31. Further, the spring material can be rotated by a hinge, but can be completely freely rotated. Since things may allow insects and small animals to enter or hang down due to their own weight, it is desirable to regulate the return to a predetermined position by a biasing means or the like in a free state.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS. In this example, the longitudinal direction of the brush base portion 14 of the gap brush is arranged in the vertical direction and is attached to the attachment location 50. Therefore, the structure of the fixing portion 41 is changed, and the other structure is the same as that of the first embodiment, so that the description thereof is omitted.

In the example of FIG. 1, the connection portion 42 is directly connected to the fixed portion 43 at a right angle. However, in the example of FIG. 5, the connection portion 42 is arranged with an acute angle with respect to the fixed portion 43. ing. Further, the connection portion 42 is connected to the fixed portion 43 via the front and rear interposition portions 46.

As shown in FIG. 6, the gap brush is attached to the left and right ends of the shutter in the vertical direction. Therefore, the attachment location 50 is assumed to be a wall surface on the left and right sides of the shutter. In the example of FIG. 6 as well, the brush body 11 can be attached to both the inside and the outside of the shutter, but from the viewpoint of preventing intrusion from the outside, the brush body 11 may be arranged on the outside (left side in the figure). Is appropriate. In this case, it is appropriate that the brush bristles 13 are arranged at an angle with respect to the shutter slats 51 in a plan view, and the above-described structure is adopted. In this example, the intermediate portion 31 is curved in the middle in the width direction as in the previous example, and as shown in FIGS. 5 and 6, the middle in the width direction protrudes to the opposite side of the shutter. As shown in FIG.
In addition, when the brush for gap | interval is arrange | positioned vertically, since the bristle 13 needs to contact | abut both the peak and trough of the slat 51, compared with the trough part, the bristle 13 is compared with the trough part. Is slightly deformed.

(Passing suppression mode)
Usually, in the brush for gaps, the fixing portion 41 is disposed at an attachment location 50 on the fixed side such as a building. On the other hand, the brush main body 11 is installed at a predetermined angle with respect to an opening / closing member such as a slat 51 of the shutter, and a tip thereof abuts on the slat 51 or the like. This suppresses the entry of foreign matter into the building from the gap between the building and the opening / closing member. A state in which the shutter is installed at a predetermined angle with respect to an opening / closing member such as the slat 51 is a passage restraint state.

However, the shutter is opened and closed frequently every day. At that time, when the shutter is opened and closed, a large number of slats 51 are wound up and rewound to be opened and closed. At the time of opening and closing, the slat 51 moves up and down while bending back and forth. Further, the vertical cross section of the slat 51 is generally curved, and the shutter has a shape in which peaks and valleys are repeated even in a stationary state. Further, a seat plate having a front and rear width of at least about 6 cm is horizontally disposed at the lower end of the shutter, and this seat plate projects from the slat 51 by about 30 mm in the front and rear directions.

On the other hand, since the clearance brush is fixed at a fixed angle with respect to the shutter in the passage restraining form, the brush bristles 13 are usually elastically deformed, so that the above-mentioned forward / backward movement of the shutter and the change of the position are performed. It corresponds to.
On the other hand, in the embodiment of the present invention, the brush body 11 can move in the front-rear direction by providing the intermediate portion 31. As a result, even if the forward / backward movement at the time of opening / closing of the shutter becomes large, the change is not absorbed only by the brush hair 13 but is absorbed by the forward / backward movement of the brush body 11 by the intermediate portion 31. As a result, it is possible to suppress an increase in resistance at the time of opening and closing the shutter and a large noise.

Examples of the present invention will be described below, but the present invention should not be understood to be limited to these examples.
(Examples 1 and 2 and Comparative Example 1)
Example 1 A gap brush as shown in FIG. 1 was prepared. A brush body 11 (50 cm in length on the left and right) having polypropylene brush hairs 13 having a wire diameter of 0.8 mm and a brush hair length of 60 mm was attached to the attachment member 20. The attachment member 20 has an intermediate portion 31 made of soft vinyl chloride, and other portions made of hard vinyl chloride.

Example 2: A gap brush as shown in FIG. 4 was prepared. The same brush body 11 as in Example 1 was attached to the attachment member 20. The attachment member 20 has an intermediate portion 31 made of soft vinyl chloride, and other portions made of hard vinyl chloride.
Comparative Example 1: The same brush body 11 as in Example 1 was directly attached to a hard metal plate.

(Pressing test)
As shown in FIG. 7, the brush body 11 was fixed so as to be horizontal. In the first and second embodiments, the fixing portion is a substantially central portion in the left-right direction of the fixing portion 41, and in Comparative Example 1, the fixing portion 41 is a substantially central portion in the left-right direction of the metal plate.

The load when pressing 15 mm downward in FIG. 7 was measured through a backing plate (50 cm × 2.5 cm) covering the entire left and right direction of the bristles 13 of Examples 1 and 2 and Comparative Example 1. The results are shown in Table 1. In addition, the backing plate shall cover from the front-end | tip of the bristle 13 to the position of 25 mm. The measuring apparatus used the constant-speed extension type tensile tester and implemented the tensile speed at 10 mm / min.

As shown in Table 1, in Example 2, the load was substantially halved compared to Comparative Example 1, and in Example 1, the load was reduced to less than 1/10 compared to Comparative Example 1. It has been confirmed that the resistance applied to the shutter can be reduced.
