21 and 22 are roller brushes which are usually used for painting, and two roller brushes are arranged in parallel with each other. The two

roller brushes

21 and 22 arranged in parallel to each other are coupled to each other by the roller brush support 30.

The roller brush support 30 has a “c” shape as a whole by bending a metal rod. The roller brush support 30 is inserted along each of the

roller shafts

21a and 22a so as to support two roller brushes 21 and 22 so as to be parallel to each other. It consists of a portion (31, 32) and the connecting portion 33 for connecting the insertion portion (31, 32) to each other at the side end. That is, the overall shape of the two

insertion portions

31 and 32 and the connecting portion 33 forms a "c" shape.

The through hole 35 is formed at an intermediate portion of the connecting portion 33 of the roller brush support 30. A through hole 35 having a diameter in which one end portion 52 of the handle connecting rod 50 is inserted is formed by forming a relatively wide surface by forming a compression deformation portion 36 compressed by a press in the middle portion of the connection portion 33. To be formed. The forming direction of the through hole 35 is the direction in which the

roller shafts

21a and 22a face, and the middle portion of the connecting portion 33 is formed so that the through hole 35 can be easily formed in the connecting portion 33 made of a metal rod. After pressing by this press, the through hole 35 is drilled.

The handle 40 is disposed to face the roller brushes 21 and 22, and the other end of the handle connecting rod 50 is fixed to the handle 40. Since the handle 40 is disposed to face an approximately intermediate position of the roller brushes 21 and 22, the handle connecting rod 50 is coupled to the connection portion 33 of the handle 40 and the roller brush support 30. It has a bent shape as described above, in particular, one end 52 of the handle connecting rod 50 is bent and inserted into the through hole 35. One end portion 52 of the handle connecting rod 50 is a portion which is bent at approximately right angles in the handle connecting rod 50 and extends in a direction in which the

roller shafts

21a and 22a are parallel to each other, and is formed at the connecting portion 33. It is inserted into the through hole 35.

On the other hand, one end portion 52 of the handle connecting rod 50 inserted into the through hole 35 is provided with one side washer 61 and the other side washer 62 with the connection portion 33 therebetween, and the one side One side support means 67 and the other side support means 54 are installed on both sides with the washers 61 and the other side washers 62 interposed therebetween. An elastic body is disposed between the one side support means 67 and the one side washer 61 to apply an elastic force to closely contact the one side washer 61, the connection part 33, and the other side washer 62 to the other side support means 54. Is installed.

The one side washer 61 and the other side washer 62 are in close contact with both sides of the compression deformation portion 36 of the connecting portion 33, the other member is in contact with the compression deformation portion 36, as in the action of a conventional washer. And to assist the smooth rotation of the handle connecting rod 50 inserted into the through hole 35. The one side washer 61 or the other side washer 62 may be omitted, but it is preferable that the washer is installed on at least the opposite side where the elastic body is installed based on the crimping deformation portion 36. That is, when the other side washer 62 is installed on the opposite side where the elastic body is installed on the basis of the pressing deformation part 36 so that the elastic body directly applies the elastic force to the pressing deformation part 36, the other side washer 62 is the pressing deformation part on the opposite side. (36) is to be in surface contact with the support. By the surface contact, the connecting portion 33 can be erected in a state perpendicular to the longitudinal direction of the one end portion 52 of the handle connecting rod 50.

The other side supporting means 54 supports the position of the other side washer 62 at the rear side of the other side washer 62 to prevent the other side washer 62 from moving to the rear side, one end of the handle connecting rod 50 ( 52) means is fixed in position. It is preferable that the other side washer support ring 66 is installed between the other side support means 54 and the other side washer 62 to form a stable support state of the other side washer 62. The other washer support ring 66 may itself serve as the other washer 62. In the present embodiment, the other support means 54 is implemented as a protrusion that partially deforms the surface of the one end portion 52 of the handle connecting rod 50, but may also be a support ring 64 fixed by welding.

The one side support means 67 is formed of a protrusion that partially deforms the surface of the one end portion 52 of the handle connection rod 50, as in the other support means 54 described above, or one end of the handle connection rod 50. It can be a stop washer, which is forcibly fitted in the 52 and its installation position can be fixed. However, in this embodiment, the one side support means 67 is composed of a nut coupled to the end of the one end 52 so as to change its position. The nut is coupled to form a spiral 57 at the end of one end 52 of the handle connecting rod 50, and the position of the nut can be changed by rotating the nut. The elastic force of the elastic body mentioned later can be adjusted by adjusting the position of a nut.

Both ends of the elastic body are supported between the one side support means 67 and the one side washer 61 to closely contact the one side washer 61, the connection part 33, and the other side washer 62 to the other side support means 54. The elastic body is preferably a coil spring 70 having a large wire diameter so as to have a strong elastic force, and a wave washer described later may be employed.

By rotating the nut to move the position of the nut toward the connection portion 33 side of the roller brush support 30 can be increased more elastic force.

In addition, it is preferable to further provide a support washer 63 for supporting the coil spring 70 between the one side support means 67 and the coil spring 70 which is an elastic body. This allows the relative rotation between the members to occur smoothly so that when the one end portion 52 of the handle connecting rod 50 is rotated in the state inserted into the through hole 35, the other members such as the coil spring 70, which is an elastic body By allowing it to rotate freely, the rotational movement of one end 52 of the handle connecting rod 50 is not disturbed.

Next, the operation of the paint roller according to the first embodiment will be described.

When the roller brushes 21 and 22 of the painting roller of the present embodiment shown in FIG. 4 receive a force from one side of the roller brushes 21 and 22 by the painting operation as shown in FIG. 2, the roller brush support 30 And the bending force of the roller brush support 30 at the engaging portion of the handle connecting rod 50.

Accordingly, the compression deformation portion 36 of the roller brush support 30 is inclined, and similarly to the case of FIG. 3, one side washer 61 and the other side washer 62 are to be pushed out.

However, in the process, as shown in FIG. 6, the elastic body is a coil spring 70, and the protrusions of the other side washer 62 and the connection part 33 of the pressing deformation part 36 and the one side washer 61 are the other supporting means 54. It adheres strongly to the side. Then, the one side washer 61 is pushed by the coil spring 70, which is an elastic body, to be in close contact with the crimping deformation portion 36, and at the same time, the crimping deformation portion 36 is also pushed toward the other supporting means 54 side. In addition, the pressing deformation part 36, the other side washer 62, and the other side washer support ring 66 are pushed in close contact with each other in a state of making surface contact. Even without the one side washer 61, the coil spring 70, which is an elastic body, is pushed toward the other support means 54 in a state in which the pressing deformation portion 36 and the other washer 62 are in surface contact.

Such a surface contact action is to mitigate the inclination of the pressing deformation portion 36 of the connecting portion 33, the greater the elastic force of the coil spring 70, which is the elastic body, the effect can be more surely generated.

Accordingly, the degree of inclination may be alleviated by the elastic force of the elastic body 70 in a state in which the compression deformation portion 36 of the connection portion 33 is inclined. Accordingly, the inner circumferential surface of the through hole 35 of the connecting body does not strongly adhere to the surface of the one end portion 52 of the handle connecting rod 50, and the one end portion of the handle connecting rod 50 is formed in the through hole 35. The rotation of 52 may occur smoothly.

7 is a configuration explanatory diagram for explaining the configuration of the roller for painting according to the second embodiment of the present invention.

Referring to FIG. 7, in this embodiment, the position of the elastic body is installed on the opposite side to the above-described embodiment, and the one side washer 61 and the other side washer 62 are sandwiched between the pressing deformation part 36 of the connection part 33. ) And the one side support means 67 and the other side support means 54 are provided on both sides with the one side washer 61 and the other side washer 62 interposed therebetween. .

However, the elastic body is supported at both ends between the other side support means 54 and the other side washer 62 so that the pressing deformation portion 36 and one side washer 61 of the other side washer 62 and the connecting portion 33 are supported by one side means ( 67) An elastic force is applied to bring it closer to the side. The elastic body is the coil spring 70, and the other end of the coil spring 70 is supported by the other support means 54 via the elastic support ring 69 to form a good supporting state. One side support means 67 is a nut coupled to the end of the one end 52 of the handle connecting rod 50, the other support means 54 is behind the one end 52 of the handle connecting rod 50 It is a projection formed.

As in the above-described embodiment, the other side washer 62, the connection part 33 and the one side washer 61 are brought into close contact with the surface of the nut, which is the one side support means 67, and the pressing deformation part of the connection part 33 ( 36) mitigate the tilt. The greater the elastic force of the coil spring 70, which is the elastic body, the more reliably the effect can occur. In this embodiment, even if the other side washer 62 is removed, the coil spring 70, which is an elastic body, pushes the crimping deformation portion 36 to the one side washer 61 so that the surface contact occurs.

8 is an exploded perspective view illustrating a configuration of a painting roller according to a third embodiment of the present invention.

Referring to FIG. 8, the present embodiment illustrates a configuration in which the one-side washer 61 and the coil spring 70, which is an elastic body, are replaced with the wave washer 80. The wave washer 80 may also function as a washer and also as an elastic body. That is, the wave washer 80 may act as an elastic body such as a spring because the elastic force is generated while the shape that is bent like a wave along the circumference when it is compressed by the surface contact is elastically deformed.

FIG. 9 illustrates a state in which the bending force of the roller brush support 30 is acted on the combined portion of the roller brush support 30 and the handle connecting rod 50 in the state where the wave washer 80 is installed and assembled.

In the same process as described in connection with FIG. 6, the wave washer 80 strongly adheres the pressing deformation portion 36 of the other washer 62 and the connecting portion 33 to the protrusion side, which is the other supporting means 54. The elastic force is acting, the compression deformation portion 36 is pushed to the other side support means 54 side by the wave washer 80, the compression deformation portion 36, the other side washer 62 and the other side washer support ring 66 All are in close contact with each other by pushing the projections of the other side support means 54 in a state of contact.

Such action reduces the inclination of the compression deformation portion 36 of the connecting portion 33, and the greater the elastic force of the wave washer 80, the more sure the effect can occur.

10 is a configuration explanatory diagram for explaining the configuration of the roller for painting according to the fourth embodiment of the present invention.

Referring to FIG. 10, the present embodiment illustrates a configuration in which the other side washer 62 and the coil spring 70, which is an elastic body, are replaced with the wave washers 80. The wave washer 80 functions as a washer and at the same time the elastic shape is generated by the curved shape is deformed like a wave along the circumference when it is pressed can act as an elastic body such as a spring. The action is to mitigate the inclination of the compression deformation portion 36 of the connecting portion 33 as described above, the greater the elastic force of the wave washer 80, the more effective the effect can occur.

On the other hand, Figure 11 is an exploded perspective view showing the configuration of the coating roller according to the fifth embodiment of the present invention, Figure 12 is a cross-sectional view showing a combined configuration of FIG.

11 and 12, a stopper ring 88 surrounding the circumference of the elastic body of the above-described embodiment is further added to the present embodiment, and the rest of the configuration is the same as that of the above-described first embodiment. .

The stopper ring 88 of the present embodiment is for preventing excessively inclining of the crimping deformation portion 36 of the connecting portion 33 with respect to the handle connecting rod 50, and wraps around the coil spring 70 which is an elastic body. So that it is installed. The stopper ring 88 is not in close contact with the one side washer 61 and the elastic support washer 63 at the same time if the external force is not applied while the coil spring 70 is installed to be inserted therein, the one side washer 61 by the external force. ) And the elastomeric support washer 63 approach each other, the stopper ring 88 is in close contact with each other is caught.

Referring to FIG. 13, when a bending force for bending the roller brush support 30 is applied at a coupling portion of the roller brush support 30 and the handle connecting rod 50, the compression deformation portion of the roller brush support 30 is applied. While the 36 is inclined at a predetermined angle, the one side washer 61 and the other side washer 62 are pushed out similarly to the case of FIG. 3.

However, in the process, the coil spring 70, which is an elastic body, to strongly adhere the pressing deformation portion 36 and the one side washer 61 of the other side washer 62 and the connecting portion 33 to the protrusion side, which is the other side support means 54. Elastic force is working. In addition, the one side washer 61 is pushed by the coil spring 70, which is an elastic body, to be in close contact with the crimping deformation portion 36, and at the same time, the crimping deformation portion 36 is also pushed toward the other supporting means 54 side. , The pressing deformation portion 36 and the other side washer 62 is in close contact with the state to be in surface contact. Such action is the same as in the above-described embodiment.

In addition, when the bending force to bend the roller brush support 30 is excessive, the elastic force of the coil spring 70, which is an elastic body, may not be able to afford, so that the stopper ring 88 may be deformed by the bending deformation caused by the bending force ( The inclination of 36) is limited at a predetermined angle.

That is, as shown in Fig. 13, one side washer 61 is pushed by the compression deformation portion 36 in close contact with the stopper ring 88 in the state that the compression deformation portion 36 is inclined at the angle of α, and stoppering (88) is also in close contact with the elastic support washer 63, the elastic support washer 63 is also in contact with one side support means (67). In this state, the space b between the one side washer 61 and the elastic support washer 63 and the width of the stopper ring 88 are the same, and the stopper ring 88 has one side washer 61 and the elastic support washer ( 63) Since the state is tightly sandwiched between the one side washer 61 can not be tilted any more.

As a result, the stopper ring 88 prevents the compressive deformation portion 36 from tilting any more even with respect to the bending force that overcomes the elastic force of the elastic body.

The degree of inclination of the compression deformation portion 36 by the stopper ring 88 may be adjusted by adjusting the front and rear directions of the one side support means 67. That is, by slightly turning the nut, which is the one side support means 67, in the direction of the elastic support washer 63, the stopper ring 88 further restricts the inclination of the compression deformation portion 36, and the one side support means 67. Turning the in-nut to move slightly in the opposite direction to the position of the elastomeric support washer 63 allows the stopper ring 88 to allow the compression deformation portion 36 to tilt.

Fig. 14 shows a state in which the roller brush support 30 is bent by a force applied on a plane in which a pair of

brushes

21 and 22 are arranged.

Even if the bending force acts in the direction shown in FIG. 14, as in the case of FIG. 13, the stopper ring 88 prevents the pressing deformation portion 36 from tilting any more.

15 is a configuration explanatory diagram for explaining the configuration of the roller for painting according to the sixth embodiment of the present invention.

This embodiment is configured by modifying the fifth embodiment, one side washer 61 and the other side washer 62 is provided with the crimping deformation portion 36 of the connecting portion 33, the one side washer 61 And the one side support means 67 and the other side support means 54 respectively disposed on both outer sides with the other side washers 62 interposed therebetween.

However, the elastic body has an elastic force so that both ends are supported between the other supporting means 54 and the other side washer 62 so that the other side washer 62 and the connecting portion 33 and one side washer 61 are in close contact with one side supporting means 67 side. Is adding. The elastic body is the coil spring 70, and the other end of the coil spring 70 is supported by the other support means 54 via the elastic support ring 69 to form a good supporting state. One side support means 67 is a nut coupled to the end of the one end 52 of the handle connecting rod 50, the other support means 54 is behind the one end 52 of the handle connecting rod 50 It is a projection formed. In addition, the stopper ring 88 is disposed to surround the outer circumferential surface of the coil spring 70, which is an elastic body, so that the crimping deformation portion 36 is no longer inclined against the excessive bending force that overcomes the elastic force as in the fifth embodiment. I'm blocking it.

On the other hand, Figure 16 is a perspective view showing the configuration of the roller for painting according to the seventh embodiment of the present invention.

Referring to FIG. 16, in the present embodiment, an elastic support washer 68 for supporting the elastic body 70 is installed between the nut, which is one side supporting means 67, and the coil spring 70, which is an elastic body, and the elastic support washer 68. Has both

side legs

681 and 682.

The two

leg members

681 and 682 respectively land on the connecting portion 33 on both sides of the through hole 35 of the connecting portion 33. For the landing, concave grooves 681a are formed at the ends of both

leg members

681 and 682, respectively, and the concave grooves 681a are seated in contact with the periphery of the outer circumferential surface of the connecting portion 33 which is a rod.

In order to form the

leg members

681 and 682, it is necessary to increase the diameter of the elastic support washer 68, and also to increase the diameter of the nut supporting the elastic support washer 68.

Both

leg members

681 and 682 prevent one end portion 52 of the handle connecting rod 50 from being shaken about the through hole 35. That is, as shown in FIG. 16 when relative shake occurs between the one end portion 52 of the handle connecting rod 50 and the roller brush support 30 around the through hole 35 in the direction indicated by "A". Both

leg members

681 and 682 of the elastic support washer 68 supported by the elastic body 70 are firmly supported to suppress relative shaking.

On the other hand, Figure 17 shows an eighth embodiment of the present invention, one end washer 52 of the handle connecting rod 50 inserted into the through hole 35, the one side washer with the connecting portion (33) in between ( 61 and the other side washer 62 is installed, the elastic force is applied to the elastic coil spring 70 to close the one side washer 61, the connecting portion 33 and the other side washer 62 to the other support means 54 side. I am adding.

The one side washer 61 and the other side washer 62 are in close contact with both sides of the compression deformation portion 36 of the connecting portion 33, and the other member does not directly contact the compression deformation portion 36 as in the action of a conventional washer. And to assist the smooth rotation of the handle connecting rod 50 inserted into the through hole 35.

In this embodiment, the cylindrical stopper 86 is fitted to one end 52 of the handle connecting rod 50 between the one side washer 61 and the coil spring 70 which is an elastic body.

The cylindrical stopper 86 is open at one side 861 so that the coil spring 70, which is an elastic body, is enclosed around the coil spring 70, and a center hole 862 is formed at the center of the handle connecting rod at the other side. One end 52 of 50 is inserted. Accordingly, as shown in FIG. 18, both ends of the coil spring 70, which is an elastic body, are supported by an elastic support washer 63 and a cylindrical stopper 86, one end of which is supported by one side supporting means 67, and a cylindrical stopper. The 86 is in close contact with the other side support means 54 together with the one side washer 61, the connecting portion 33, and the other side washer 62.

In addition, the elastic support washer 63 is surrounded by a cylindrical stopper 86.

With such a configuration, as shown in FIG. 18, when the compression deformation portion 36 of the connecting portion 33 is inclined at an angle of γ, one side washer 61 is attached to the compression deformation portion 36 by the coil spring 70 which is an elastic body. The cylindrical stopper 86, which is in close contact with each other, is also inclined at the angle of γ. At this time, the inner surface of the cylindrical stopper 86 is in contact with the elastic support washer 63 provided at one end 52 of the handle connecting rod 50, the cylindrical stopper 86 is prevented from tilting any more. This is because the cylindrical stopper 86 also prevents the inclination of the crimp deformation portion 36 in close contact with the one side washer 61 by the coil spring 70, which is an elastic body, so that the inclination of the connecting portion 33 is set. It can be blocked in range.

On the other hand, Figure 19 shows a ninth embodiment of the present invention, the one end 52 of the handle connecting rod 50 inserted into the through hole 35, the other side washer with the connecting portion 33 therebetween ( 62) and an elastic wave washer 80 is installed.

In this embodiment, the reinforcing bar 91 is landed and fixed to the crimping deformation part 36 of the connection part 33 to reinforce the crimping deformation part 36. The reinforcing rod 91 is fixed to the connecting portion 33 by spot welding, the diameter of the one end portion 52 of the handle connecting rod 50 or the through hole 35 of the pressing deformation portion 36 It has a through hole formed larger than the diameter of the one end 52 of the handle connecting rod 50 to facilitate the passage of the through hole of the reinforcing rod (91).

The cylindrical body 92 is in the state fixed to the reinforcement stand 91, and since the reinforcement stand 91 is fixed to the connection part 33, the cylinder 92 is also fixed to the connection part 33 after all.

The cylindrical body 92 is installed in a state surrounding the one end 52 of the handle connecting rod 50 inserted into the through hole 35.

In the cylindrical body 92, a wave washer 80, a cylindrical spacer 83, and one side support means are installed at one end 52 of the handle connecting rod 50.

The one side support means is a disk-shaped stopper 87 in the present embodiment, the disk-shaped stopper 87 is positioned at one side of the cylindrical spacer 83 when forcibly fitted to one end 52 of the handle connecting rod 50. Can be fixed. The disk-shaped stopper 87 may employ a stop washer specifically known. The disc-shaped stopper 87 may also be installed by being fitted to one end portion 52 of the handle connecting rod 50 separately from the one side support means.

In addition, the disk-shaped stopper 87 is installed so that its outer peripheral surface is a small gap with the inner surface of the cylindrical body 92, the movement of the disk-shaped stopper 87 is restricted by the cylindrical body 92 Limit the inclination of one end 52 of the handle connecting rod (50).

In this embodiment, the wave washer 80 is in close contact with the reinforcing rod 91 and the connecting portion 33 is fixed to the other side support means 54.

With such a configuration, as shown in FIG. 20, when the crimping deformation portion 36 of the connecting portion 33 is inclined at the angle of γ, the cylindrical body 92 fixed to the connecting portion 33 via the reinforcing table 91 is also used. Tilted at an angle. At this time, the inner surface of the cylindrical body 92 is in contact with the outer circumferential surface of the disc-shaped stopper 87 provided at one end 52 of the handle connecting rod 50, the cylindrical body 92 is prevented from tilting any more. have. This restricts the inclination of the connecting portion 33 which is in close contact with the other supporting means 54 by the wave washer 80 within the setting range, and the cylinder is applied when an excessive external force cannot be alleviated by the wave washer 80. The sieve 92 and the disc shaped stopper 87 limit the inclination limit.

The cylindrical spacer 83 is for simply adjusting the distance between the wave washer 80 and the disc-shaped stopper 87, and the cylindrical spacer 83 and the wave washer 80 may be replaced by a coil spring.

In the above-described embodiments, both the washer and the other washer may be replaced with a wave washer, and the wave washer may serve as an elastic body together with the role of the washer.

21 and 22 show a tenth embodiment of the present invention, which is a very simplified configuration of the above-described embodiment.

Referring to FIG. 21, in the present embodiment, a roller brush support 30 having a “c” shape is installed, and a crimping deformation portion 36 is installed at a connection portion 33 of the roller brush support 30.

The pressing deformation portion 36 is a portion included in the connecting portion 33, and is pressed in a direction parallel to the

roller shafts

21a and 22a by a press in the middle portion of the connecting portion 33. Therefore, the pressing surface faces the direction parallel to the

roller shafts

21a and 22a, and the through hole 35 penetrating the pressing deformation portion 36 also faces the direction parallel to the

roller shafts

21a and 22a.

In this embodiment, an elastic body is installed at one side of the one end portion 52 of the handle connecting rod 50 inserted into the through hole 35 based on the crimping deformation portion 36. The elastic body may be a coil spring 70 or a wave washer as in the above-described embodiment.

On the other side of the crimping deformation portion 36, that is, the opposite side on which the coil spring 70, which is an elastic body, is installed, a supporting means is provided to support the connecting portion 33 that is pushed by the elastic body 70.

The supporting means is to support the connecting portion so that the connecting portion 33 is perpendicular to the longitudinal direction of the one end portion 52, in this embodiment by welding to one end 52 of the handle connecting rod 50 It is implemented with a fixed bearing ring 64.

When the pressing deformation portion 36 of the connecting portion 33 pushed by the elastic body 70 is in close contact with the support ring 64, one end portion 52 of the handle connecting rod 50 is in close contact with the support ring 64. ), The connecting portion 33 can be erected in a state perpendicular to the longitudinal direction of the one end portion 52.

That is, as shown in FIG. 22, the coil spring 70, which is an elastic body, supports the crimping deformation portion 36 inclined at an angle of α with respect to the longitudinal direction of the one end portion 52 of the handle connecting rod 50 (64). When pressed to the side), the pressing deformation portion 36 is in close contact with the support ring 64, the connection portion 33 can be erected in a direction perpendicular to the longitudinal direction of the one end portion 52 of the handle connecting rod 50. This is to alleviate the inclination of the through hole 35 with respect to the one end 52 of the handle connecting rod 50, so that the one end 52 of the handle connecting rod 50 in the through hole 35 to rotate smoothly. do.

Since the supporting means is a means for supporting the connecting portion so that the connecting portion 33 is perpendicular to the longitudinal direction of the one end portion 52, the other supporting means 54, the other side standing support ring 66 and the other side in FIG. The structure consisting of the washers 62 is a supporting means.

When the elastic body 70 is installed on the side opposite to the position installed in FIG. 5 as shown in FIG. 7, the structure consisting of one side washer 61 and one side supporting means 67 becomes a supporting means.

The present invention can be usefully used in the technical field of manufacturing a paint roller for painting paint on a wall or the like.
