Description

Paint roller {Paint roller}

The present invention relates to a paint roller, and more specifically, a first stopper for replacing and using a roller member for painting, but both ends of a handle bar rotatably supporting the roller member to block one end of the roller member, and The present invention relates to a paint roller capable of stably rotating a roller member with respect to a handle bar by stably positioning it in a sealing support coupled to a second stopper blocking the other end.

In general, the paint roller paints the surface while the roller member to which the paint is adsorbed rolls with respect to the grip rod. Among these paint rollers, a paint roller configured to be used by replacing a roller member from a handle bar is already known.

For example, in Korean Patent Publication No. 10-2011-0139877 (published on Dec. 30, 2011; brush replaceable paint roller), a stopper is coupled to one open end of a roller member whose other end is blocked and one end is open. A rolling barrel that is loosely inserted into the pocket portion and operates in a rolling manner is coupled to the pocket portion formed at the insertion end of the stopper. In addition, a fixed hollow is formed through the center of the rolling barrel, and a handle bar is inserted into the fixed hollow. Through this configuration, the handle bar is configured to be rotatable with respect to the stopper using the rolling barrel. Furthermore, the roller member integrally coupled with the stopper is rotatable with respect to the handle bar.

In the prior art, the handlebar is configured to be supported only by one stopper coupled to one end of the roller member. In this configuration, when the length of the roller member is relatively short, the rotational motion of the roller member relative to the handlebar can be stably maintained. However, when the length of the roller member is relatively long or the pull bar is inserted to the other end of the roller member, there is no structural means to support the pull bar inserted at the other end of the roller member, so the roller member for the handle bar There is a problem that stable rotation operation cannot be guaranteed.

In domestic utility model registration No. 20-0450269 (registered on September 9, 2010; paint roller), which has been supplemented with the problems of the prior art, a pair of stoppers having through-holes are closely installed at both ends of a hollow roller member. . A fixing hole is penetrated in the center of one of the stopper through-holes, and a fixed rolling pin having an incision slot communicating with the fixing hole is installed on one side.

Through this configuration, the handle bar is inserted into the through hole of the stopper tightly coupled to one end of the roller member and exposed to the outside while being inserted into the fixing hole of the fixed rolling pin installed on the stopper of the other end of the roller member. At this time, the fixed rolling pin allows the handle bar to be inserted by widening the incision slot provided on the side as the handle bar enters the fixing hole, and the handle bar inserted in the fixed bar is supported by the fixed rolling pin and is rotatable with respect to the stopper. becomes Accordingly, while the roller member rotates with respect to the handlebar, painting is performed.

However, in the prior art, a fixed rolling pin for supporting the handle rod using a fixing hole and a cutting slot is installed on the through hole of the stopper installed at the other end of the roller member while being exposed to the outside. When the fixed rolling pin supporting the handle bar is exposed to the outside, the paint can flow into the roller member through the rolling space between the exposed fixed rolling pin and the through hole of the stopper, as well as the fixed rolling pin and When paint flows in between the through holes of the stopper and hardens, a problem may occur in that the rolling motion of the fixed rolling pin is not smooth in the through hole of the stopper. In addition, since the fixed rolling pin is exposed outside the stopper, in the case of the corner where the face and face face each other (for example, the inner angle part of the 'a' shape), the fixed rolling pin exposed outside the stopper is different from the other surface that is not painted. Because it is in contact, there is a problem that the painting of the corner part in contact with the end must be painted using a separate paint brush.

Patent Publication No. 10-2011-0139877 (published on December 30, 2011) Registered Utility Model No. 20-0450269 (registered on September 9, 2010)

The present invention is to solve the above problems of the prior art, in providing a paint roller capable of replacing a roller member, adopting a simple and concise configuration, but the adopted configuration is different from the prior art configuration Its purpose is to provide a paint roller.

In addition, the paint roller of the present invention is installed in the stopper blocking the other end of the roller member to support the entry end of the handle bar entering the through hole of the stopper blocking one end of the roller member, but installed on the hollow of the roller member Its purpose is to provide a paint roller that can improve convenience in use by preventing exposure to the outside of the stopper.

In order to achieve the above object, the present invention provides a paint roller capable of replacing a roller member rotatably coupled to a handlebar, comprising: a roller member having a hollow penetrating both sides along a longitudinal direction; a first stopper having a through hole formed in the center and blocking one end of the hollow to prevent inflow of paint; a second stopper integrally provided with a storage tube having a rolling hollow formed therein that communicates with the open end accommodated as the other end of the hollow and blocking the other end of the hollow to prevent inflow of paint; A sealing support that is loosely inserted into the rolling hollow so as to be rotatable and has a cutout formed on one side thereof connected to the rod fixing holes penetrating both sides along the longitudinal direction; an induction hole formed in the center and coupled to the storage pipe so that the sealing support inserted into the rolling hollow does not escape; a handle rod inserted into the through hole, past the induction hole, and force-fitted into the rod fixing hole by using elastic expansion through the incision of the sealing support to enable rotation of the roller member; It is based on a configuration consisting of

In addition, at least one end of both ends in the longitudinal direction of the sealing tool forms an guiding inclined surface whose end is inclined inward toward the rod fixing hole to induce entry of the handle rod entering the rod fixing hole through the guide hole. to be characterized

In addition, an inner circumferential frame protrudes from an inner circumferential surface at a predetermined interval from the open end of the rolling hollow of the storage pipe; The separation prevention device forms an insertion tube integrally protruding toward the storage tube from the center of the guide wall connected to the outer circumference, the insertion tube having the guide hole passing through the center and an outer circumferential locking frame protruding from the outer circumferential surface, It is characterized in that the outer circumferential hanging frame of the insertion pipe inserted into the rolling hollow is engaged with the inner circumferential hanging frame to prevent separation of the sealing support.

In addition, the rolling hollow of the storage pipe is formed with an insertion hole whose diameter is expanded at regular intervals at the open end, and the insertion hole uses a step difference between the inner circumferential frame protruding from the middle and the rolling hollow at the inner end. By forming a limiting end, the end of the insertion tube is characterized in that entry into the rolling hollow is restricted by the limiting end.

In addition, the separation prevention device forms the guide wall connecting the outer circumference frame and the insertion tube in a funnel shape in which the diameter decreases toward the insertion tube from the outer circumference frame, so that the handle bar guides the guide hole through the guide wall. It is characterized by being inserted into.

In addition, the outer circumference of the release prevention device is in close contact with the hollow inner circumferential surface of the rolling member, and a plurality of contact protrusion pieces are protrudingly formed on the outer circumference of the outer circumference at regular intervals, so that the detachment prevention device is formed through the adhesion protrusion pieces. It is characterized in that it adheres to the inner circumferential surface of the hollow.

In the paint roller according to the present invention, a sealing tool supporting the entry end of the handle rod entering the through hole of the first stopper is installed on the second stopper blocking the other end of the roller member, and the insertion of the second stopper inserted into the hollow of the roller member A storage pipe having a rolling hollow, which is an internal space, is provided at an end thereof, and a sealing support supporting an entry end of the handle bar is rotatably inserted into the rolling hollow. In addition, a release prevention device is coupled to an open end connected to the rolling hollow of the storage pipe so that the sealing support device inserted into the storage pipe does not escape.

Therefore, the handle bar has the advantage of being stably supported on both sides by the sealing support installed on the first stopper and the second stopper coupled to one end of the roller member.

In addition, the sealing support supporting the entrance end of the handle bar is installed at the insertion end of the second stopper blocking the other end of the roller member, so that there is no configuration exposed to the outside of the second stopper, and the second stopper has an end of the roller member. completely block it Therefore, even when painting the edge where the face and face face each other, such as the interior angle of 'a', there is no limitation such as the composition exposed outside the stopper being caught by the composition exposed on the unpainted surface, so the range of use is wide. Of course, since the paint is blocked by the second stopper and cannot enter the inside of the roller member, there is an advantage in that there is no concern about hardening of the paint due to the inflow of the paint even during the rotational operation of the roller member along with cleanliness.

Hereinafter, the present invention will be described in detail using the accompanying drawings. However, since the accompanying drawings show preferred embodiments of the present invention, the scope of the present invention is not limited by these drawings. In addition, even if the configuration is essential for carrying out the present invention, detailed descriptions of configurations that belong to the known technology or can be easily implemented by a person skilled in the art from the known technology will be omitted.

Referring to FIGS. 1 to 3, the paint roller of the present invention includes a roller member 10 that rotates and paints, and a first stopper 20 and a second stopper blocking both ends of the hollow 11 of the roller member 10. (30), the storage tube 31 integrally formed with the second stopper 30, the sealing support 40 loosely accommodated rotatably in the rolling hollow 31b of the storage tube 31, the sealing support ( 40) is coupled to the storage pipe 31 so that it does not escape from the storage pipe 31, and the through hole of the first stopper 20 so that the roller member 10 can rotate ( 21) and is composed of a handle rod 60 inserted and supported into the rod fixing hole 41 of the sealing device 40 via the induction hole 51 of the detachment device 50.

The paint roller according to the present invention configured as described above can be used by replacing the roller member 10 as needed, and both ends of the handle rod 60 are respectively connected to the first stopper 20 and the second stopper 30. ) It is configured to be stably supported by the sealing support 40 accommodated in the storage pipe 31. Therefore, the present invention is characterized in that constant quality of painting is possible because the roller member 10 stably rotates with respect to the handle bar 60 regardless of the relative length of the roller member 10.

The roller member 10 has a cylindrical shape and a hollow 11 penetrating both sides along the longitudinal direction is formed on the inner side.

In addition, the first stopper 20 having a through hole 21 formed in the center is tightly coupled to one end of the roller member 10 to block one end of the hollow 11 . Therefore, foreign substances including paint cannot flow into the hollow 11 inside the roller member 10 .

In addition, the second stopper 30 is tightly coupled to the other end of the roller member 10 to block the other end of the hollow 11 . Therefore, foreign substances including paint do not flow into the hollow 11 inside the roller member 10 .

Here, the insertion end of the second stopper 30 is inserted into the other end of the hollow 11, and the insertion end inserted into the other end of the hollow 11 is a receiving tube integrally formed with the second stopper 30 ( 31). A rolling hollow 31b, which is a space, is formed on the inside of the storage pipe 31. In addition, since the end corresponding to the entry end of the housing tube 31 entering the hollow 11 at the other end of the roller member 10 is formed as an open end 31a, the rolling hollow 31b is formed as an open end 31b. It has a characteristic of being connected to the outside of the storage tube 31 through the end 31a.

The sealing support 40 is inserted into the rolling hollow 31b of the housing tube 31 through the open end 31a. Here, the sealing hole 40 is formed through a hole 41 in the center along the longitudinal direction so that the entry end of the handle bar 60 can be inserted. ) It is also connected to the cutout 42 formed along one side of. Therefore, the cross section in the width direction (longitudinal direction and vertical direction) of the sealing tool 40 has a shape like the letter "C". Due to this configuration of the sealing support 40, the handle rod 60 is inserted along the rod fixing hole 41 and the cutout 42 widens to match the circumference of the handle rod 60, and accordingly the sealing support ( 40) has a characteristic of elastic expansion in the width direction as a whole. At this time, even if the sealing support 40 elastically expands in the width direction, the outer circumferential surface of the sealing support 40 and the inner circumferential surface of the rolling hollow 31b maintain a spaced distance at regular intervals. In this way, the sealing support 40 elastically adheres to and supports the handle bar 60 inserted into the rod fixing hole 41, and the outer circumference of the sealing support 40 extended in the width direction is the inner circumferential surface of the rolling hollow 31b. Since the separation distance is maintained, the entrance end of the handlebar 60 becomes rotatable with stable support.

The sealing support 40 inserted into the rolling hollow 31b of the storage pipe 31 is a release prevention device 50 coupled to the storage pipe 31 to close the open end 31a of the storage pipe 31 escape is prevented by Here, an induction hole 51 through which the handle rod 60 passes is formed through the center of the separation prevention device 50.

Finally, the handle bar 60 enters the hollow 11 of the roller member 10 through the through hole 21 of the first stopper 20 . The entry end of the pull rod 60 entering the hollow 11 of the roller member 10 passes through the guide hole 51 of the separation prevention device 50 and enters the rod fixing hole 41 of the sealing device 40. It is joined in a forced fit method. At this time, the portion of the handlebar 60 entering the hollow 11 of the roller member 10 is naturally in a straight line shape, and one end of both ends of the straight handlebar 60 is supported by the first stopper 20, and the other end is supported by the first stopper 20. The end is supported by the sealing support 40 inserted into the housing tube 31 of the second stopper 30. Since both ends of the pull rod 60 entering the roller member 10 are stably supported, the roller member 10 always enables a stable rotational operation with respect to the pull rod 60.

A preferred embodiment of the paint roller of the present invention based on the above configuration will be examined in detail.

As shown in FIG. 2, the roller member 10 has a cylindrical roller housing 12 in which a hollow 11 penetrating in both directions is formed on the inside, and a painted portion formed on the outer circumferential surface of the roller housing 12. (13). The painting unit 13 is for painting a target surface, but may also be a pattern means for creating a certain pattern on a target surface.

And, as shown in FIG. 2, both the first stopper 20 and the second stopper 30 coupled to both ends of the roller housing 12 have insertion frames 23 and 33 inserted into the hollow 11. can be formed In addition, it is preferable that flanges 22 and 32 in close contact with the ends of the roller housing 12 are formed at outer ends of the insertion frames 23 and 33 . As the flanges 22 and 32 provided at the outer ends of the first stopper 20 and the second stopper 30 come into close contact with both ends of the roller housing 12, the paint adsorbed to the painting part 13 Inflow into the hollow 11 of the roller housing 12 is blocked. In addition, as shown in the enlarged view of FIG. 2 and FIG. 3, preferably, a plurality of contact pieces 24 and 34 are protruded from the outer circumferential surface of the insertion frames 23 and 33 at regular intervals, and the contact pieces 24 , 34) is closely coupled to the inner circumferential surface of the hollow 11 at both ends of the roller housing 12. Here, the contact pieces 24 and 34 may be composed of contact parts 24b and 34b and entry inclined parts 24a and 34a. The close contact portions 24b and 34b secure a bonding force by which the insertion frames 23 and 33 are stably inserted and maintained in the hollow 11, and the entry inclined portions 24a and 34a ensure that the insertion frames 23 and 33 are stably inserted and maintained. In order to induce smooth insertion into the hollow 11, the diameter of the close contact portions 24b and 34b toward the insertion start point is reduced to form an inclined surface.

In addition, as shown in the enlarged view of FIG. 2, in the rolling hollow 31b, which is the space of the storage pipe 31 formed at the insertion end of the second stopper 30, at a predetermined interval at the open end 31a, the rolling hollow ( An insertion portion 31c having a diameter larger than 31b) may be formed. Due to the insertion portion 31c having a larger diameter than the rolling hollow 31b, a step naturally occurs at the end of the rolling hollow 31b, and the step becomes the entry limiting end 31e. In addition, an inner circumferential frame 31d is further formed along the inner circumferential surface in the middle of the insertion portion 31c. Naturally, the opposite end of the entry limiting end 31e in the insertion part 31c is the open end 31a.

Corresponding to the configuration of the insertion portion 31c, which is the end of the storage pipe 31 as described above, the separation prevention device 50 inserted into the insertion portion 31c is preferably connected to the outer rim 55. An insertion tube 52 protrudes integrally from the center of the guide wall 54 toward the storage tube 31 . The entrance end, which is the end of the insertion tube 52, is configured to restrict entry into the rolling hollow 31b by the entry limiting end 31e. As the entry of the insertion tube 52 into the rolling hollow 31b is restricted, interference between the sealing tool 40 and the insertion tube 52 inserted into the rolling hollow 31b is prevented. However, it is natural that the induction hole 51 formed in the center of the insertion tube 52 is formed through the rolling hollow 31b to communicate with it. Here, in the process of inserting the insertion tube 52 into the insertion part 31c, the outer circumference hanging frame 53 protruding from the outer circumferential surface of the insertion tube 52 holds the inner circumferential hanging frame 31d of the insertion part 31c to a strong external force. ride over by In addition, the outer circumferential hanging frame 53 of the insertion tube 52 that has crossed the inner circumferential hanging frame 31d of the insertion portion 31c is engaged with the inner circumferential hanging frame 31d. 50) is stably and fixedly coupled to the storage pipe 31.

In addition, preferably, the separation prevention device 50 extends the guide wall 54 connecting the outer rim 55 and the insertion tube 52 from the outer circumference 55 toward the insertion tube 52 in diameter. Formed in a smaller funnel shape, the handle bar 60 is guided by the induction wall 54 and configured to be inserted into the induction hole 51.

In addition, preferably, the outer circumferential frame 55 of the separation prevention device 50 is in close contact with the inner circumferential surface of the hollow 11 of the roller housing 12, and a plurality of protrusions are in close contact with the outer circumferential surface of the outer circumferential frame 55 at regular intervals. The piece 56 is protruded so that the release prevention device 50 is in close contact with the inner circumferential surface of the hollow 11 through the close contact protruding piece 56. Here, the close contact protruding piece 56 formed on the outer circumferential frame 55 of the separation prevention device 50 has an entry slope having the same function as the close contact piece 24 formed on the insertion frame 23 of the first stopper 20. It may be composed of a portion 56a and a close contact portion 56b.

On the other hand, at least one end of both ends of the sealing tool 40 in the longitudinal direction may form an induced inclined surface 43 whose end is inclined inward toward the sealing hole 41 . Preferably, the guide slopes 43 are formed at both ends of the sealing support 40 in the longitudinal direction, so that the sealing support 40 has the same action regardless of which direction the sealing support 40 is inserted into the housing tube 31 of the second stopper 30. to do In this way, since the end of the sealing support 40 is formed as an induction slope 43, the pull rod 60 passing through the guide hole 51 of the separation prevention device 50 contacts the sealing support 40 and guides it simultaneously. It is guided to the inclined surface 43 so that it can easily enter the rod hole 41.
