Description

Paint roller {Paint roller}

The present invention relates to a paint roller, and more specifically, a first stopper for which both ends of a handle bar for rotatably supporting the roller member block one end of the roller member and The present invention relates to a paint roller in which a roller member can be stably rotated with respect to a handle bar by being stably positioned on a sealing support coupled to a second stopper blocking the other end.

In general, a paint roller paints a surface while a roller member on which paint is adsorbed rolls against a handle bar. Among these paint rollers, a paint roller configured to be used by replacing a roller member from a handle bar if necessary is known.

For example, in Korean Patent Laid-Open Publication No. 10-2011-0139877 (published on December 30, 2011; brush-replaceable paint roller), a stopper is coupled to an open end of a roller member with the other end blocked and one end open. A rolling barrel that is loosely inserted into the pocket portion and rolls is coupled to the pocket portion formed at the insertion end of the stopper. And a fixed hollow is formed through the center of the rolling barrel, and the 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 a rolling barrel. Further, the roller member integrally coupled with the stopper is rotatable with respect to the handle bar.

In the prior art, the handle bar 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 operation of the roller member with respect to the handle bar may be stably maintained. However, when the length of the roller member is relatively long or the handle bar is inserted up to the other end of the roller member, since there is no structural means capable of supporting the handle bar inserted into the other end of the roller member, There is a problem that a stable rotation operation cannot be guaranteed.

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

Through this configuration, the handle bar is inserted into the through hole of the stopper closely coupled to one end of the roller member, and is exposed to the outside while being inserted into the fixing hole of the fixed rolling pin installed in the stopper at the other end of the roller member. At this time, the fixed rolling pin allows the handle rod to be inserted as the cut slot provided on the side opens as the handle rod enters the fixed hole, and the handle rod inserted into the fixed rod is supported by the fixed rolling pin and is rotatable with respect to the stopper. becomes As a result, the roller member rotates with respect to the handle bar and paints are applied.

However, in the prior art, the fixing rolling pin for supporting the handle bar using the fixing hole and the cutting slot on the through hole of the stopper installed at the other end of the roller member is installed while being exposed to the outside. In this way, when the fixed rolling pin supporting the handle bar is exposed to the outside, paint can flow into the inside of 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 the fixed rolling pin. If the paint flows in and hardens between the through-holes of the stopper, there may be a problem that the rolling motion of the fixed rolling pin is not smooth in the through-holes of the stopper. In addition, since the fixed rolling pin is exposed outside the stopper, in the case of an edge where the face and the face face each other (for example, an 'a'-shaped inner cabinet part), the fixed rolling pin exposed outside the stopper is exposed to the other side not being painted. Since it is in contact, there is a problem in that the painting of the edge portion 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 Sep. 9, 2010)

The present invention is to solve the problems of the prior art, and in providing a paint roller with a replaceable roller member, a simple and concise configuration is adopted, but the adopted configuration is different from that of the prior art. It is an object to provide a paint roller.

In addition, in the paint roller of the present invention, a sealing support for supporting the entry end of the handle bar that has entered the through hole of the stopper blocking one end of the roller member is installed on the stopper blocking the other end of the roller member, but installed on the hollow of the roller member It is an object of the present invention to provide a paint roller capable of improving convenience in use by not being exposed to the outside of the cap.

The present invention for achieving the above object is a paint roller that can replace a roller member rotatably coupled to a handle bar, comprising: a roller member having a hollow passing through both sides along the longitudinal direction; a first stopper having a through hole formed in the center and blocking one end of the hollow to prevent the inflow of paint; a second stopper for blocking the other end of the hollow so as to prevent the inflow of paint by integrally having an accommodating tube having a rolling hollow communicating with the open end accommodated as the other end of the hollow; a sealing support which is loosely inserted into the rolling hollow so as to be rotatable, and has a cutout connected to the rod fixing hole passing through both sides in the longitudinal direction on one side; a separation prevention device having a guide hole penetrating through the center and coupled to the housing tube so that the sealing member inserted into the rolling hollow is not separated; a handle bar inserted into the through-hole, passing through the guide hole, and press-fitted to the bar fixing hole using elastic expansion through the cutout of the sealing member to enable rotation of the roller member; It is based on the composition consisting of

In addition, at least one end of both ends in the longitudinal direction of the sealing support forms a guide inclined surface whose end is inclined inward toward the rod fixing hole, so as to induce the entry of the handle bar that passes through the guide hole and enters the rod fixing hole. characterized.

In addition, in the rolling hollow of the housing tube, an inner circumferential locking frame is formed to protrude from the open end at a predetermined interval on the inner circumferential surface; The separation prevention device forms an insertion tube integrally protruding toward the receiving tube from the center of the guide wall connected to the outer periphery, and the insertion tube includes the guide hole penetrating in the center and an outer circumferential locking frame protruding from the outer circumferential surface, The outer circumferential locking frame of the insertion tube inserted into the rolling hollow is engaged with the inner circumferential locking frame to prevent separation of the encapsulant.

In addition, in the rolling hollow of the housing tube, an insertion hole having an enlarged diameter at a predetermined distance from the open end is formed, and the insertion hole is formed using a step difference between the inner circumferential locking frame protruding in 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 the entry into the rolling hollow by the limiting end is restricted.

In addition, the escape prevention device forms the guide wall connecting the outer periphery and the insertion tube in a funnel shape that decreases in diameter from the outer periphery toward the insertion tube, so that the handle bar is the guide hole of the guide wall It is characterized in that it is inserted into.

In addition, the outer periphery of the separation preventing device is in close contact with the hollow inner circumferential surface of the rolling member, and forming a plurality of close contact protrusions protruding at a predetermined interval on the outer circumferential surface of the outer periphery, through the close contact protrusions, the separation preventing tool It is characterized in that it is in close contact with the hollow inner circumferential surface.

In the paint roller according to the present invention, a sealing support supporting the entry end of the handle rod that has entered the through hole of the first stopper is installed on the second stopper blocking the other end of the roller member, but the insertion of the second stopper inserted into the hollow of the roller member A housing tube having a rolling hollow, which is an inner space, is provided at the end, and a sealing member supporting the entry end of the handle bar is rotatably inserted into the rolling hollow. And the open end connected to the rolling hollow of the housing tube is coupled to the release preventing member so that the sealing member inserted into the housing tube is not separated.

Therefore, there is an advantage that the handle bar is 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 for supporting the entry 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 to be exposed outside the second stopper, as well as the second stopper is the end of the roller member completely block Therefore, the range of use is wide because there is no restriction such as the composition exposed to the outside of the stopper being caught on the surface that is not painted by the composition exposed outside the stopper even when painting the corner where the surface and the surface face each other, such as the interior angle of 'A'. Of course, since the paint is blocked by the second stopper and does not enter the inside of the roller member, there is an advantage that there is no concern about the occurrence of a phenomenon of hardening of the paint due to the inflow of the paint even during the rotating operation of the roller member with cleanliness.

Hereinafter, the present invention will be described in detail with reference to 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 it is a configuration essential for carrying out the present invention, a detailed description of the configuration that belongs to the known art or can be easily implemented by a person skilled in the art from the known technology will be omitted.

1 to 3, the present invention paint roller rotates and paints a roller member 10, and a first stopper 20 and a second stopper blocking both ends of the hollow 11 of the roller member 10 (30), the housing tube 31 integrally formed with the second stopper 30, the sealing holder 40 loosely accommodated in the rolling hollow 31b of the housing tube 31, and the sealing holder ( A through hole of the first stopper (20) so that the separation prevention device (50) coupled to the receiving pipe (31) so that the 40) is not separated from the receiving pipe (31), and the roller member (10) is rotatable ( 21), it is composed of a handle bar 60 that is inserted and supported in the bar fixing hole 41 of the sealing member 40 through the guide hole 51 of the separation prevention device 50.

The paint roller according to the present invention configured as described above can be used by replacing the roller member 10 as necessary, and both ends of the handle bar 60 are the first stopper 20 and the second stopper 30, respectively. ) is a configuration that is stably supported by the sealing support 40 accommodated in the housing tube 31 . Therefore, according to the present invention, the roller member 10 stably rotates with respect to the handle bar 60 irrespective of the relative length of the roller member 10 , so that painting of a certain quality is possible.

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

And the first stopper 20 having a through hole 21 formed in the center of one end of the roller member 10 is closely coupled 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 closely 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 second stopper 30 has an insertion end that is one end 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). The accommodating tube 31 is formed with a rolling hollow 31b that is a space inside. And, since the end corresponding to the entry end of the housing tube 31 entering the hollow 11 of the other end of the roller member 10 is formed as an open end 31a, the rolling hollow 31b is the open end. It has a characteristic of being connected to the outside of the housing tube 31 through the end 31a.

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

The sealing member 40 inserted into the rolling hollow 31b of the receiving pipe 31 is a separation preventing member 50 coupled to the receiving pipe 31 to close the open end 31a of the receiving pipe 31 . escape is prevented by Here, a guide hole 51 through which the handle rod 60 passes is formed in 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 handle rod 60, which entered the hollow 11 of the roller member 10, passes through the guide hole 51 of the separation prevention device 50 and is inserted into the rod fixing hole 41 of the sealing member 40. It is joined in a force-fitting manner. At this time, the part of the handle bar 60 entering the hollow 11 of the roller member 10 is of course in a straight shape, and one end of both ends of the straight handle bar 60 is supported by the first stopper 20, and the other The end is supported by the sealing member 40 inserted into the receiving tube 31 of the second stopper 30 . Since both ends of the handle bar 60 entering into the roller member 10 are stably supported, the roller member 10 is always capable of a stable rotational operation with respect to the handle bar 60 .

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

As shown in FIG. 2, the roller member 10 has a cylindrical shape and a roller housing 12 having a hollow 11 penetrating in both directions on the inside, and a painted part formed on the outer circumferential surface of the roller housing 12. (13) may consist of. The painting part 13 is for painting a desired surface, but may be a pattern means for making a certain pattern on a desired surface.

And, as shown in FIG. 2 , 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 the outer ends of the insertion frames 23 and 33 . In this way, the flanges 22 and 32 provided at the outer ends of the first stopper 20 and the second stopper 30 are in close contact with both ends of the roller housing 12, respectively, so that the paint adsorbed to the painted part 13 is The 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 protrudingly formed on 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 peripheral 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 portions 24b and 34b and entry slopes 24a and 34a. The contact portions 24b and 34b ensure the coupling force that the insertion rims 23 and 33 are stably inserted and maintained in the hollow 11, and the entry inclined portions 24a and 34a are the insertion rims 23 and 33. In order to induce smooth insertion into the hollow 11, the diameter is formed to decrease toward the insertion start point from the contact portions 24b and 34b 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 accommodation tube 31 formed at the insertion end of the second stopper 30, at a predetermined interval from the open end 31a, the rolling hollow ( The insertion part 31c having a diameter larger than that of 31b) may be formed. Due to the insertion portion 31c having a larger diameter than the rolling hollow 31b, the end naturally has a step difference with the rolling hollow 31b, and the step becomes the entry limiting end 31e. And the middle portion of the insertion portion (31c) is further formed along the inner peripheral locking frame (31d) along the inner peripheral surface. Here, of course, the opposite end of the entry limiting end 31e in the insertion portion 31c is the open end 31a.

Corresponding to the configuration of the insertion portion 31c, which is the end of the housing tube 31 as described above, the separation prevention device 50 inserted into the insertion portion 31c is preferably connected to the outer periphery 55. The insertion tube 52 is integrally formed to protrude from the center of the guide wall 54 toward the accommodation tube 31 . The entry end, which is the end of the insertion tube 52, is configured such that the entry into the rolling hollow 31b is restricted by the entry limiting end 31e. As such, the insertion tube 52 is restricted from entering the rolling hollow 31b, so that the interference between the sealing member 40 and the insertion tube 52 inserted into the rolling hollow 31b is blocked. However, it is natural that the guide hole 51 formed in the center of the insertion tube 52 is formed to pass through the rolling hollow 31b. Here, in the process in which the insertion tube 52 is inserted into the insertion part 31c, the outer circumferential locking frame 53 protruding from the outer circumferential surface of the insertion tube 52 applies the inner circumferential locking frame 31d of the insertion part 31c to a strong external force. ride over by And the outer circumferential locking frame 53 of the insertion tube 52 that has crossed the inner circumferential locking frame 31d of the insertion part 31c is engaged in the inner circumferential locking frame 31d, and through this engagement, the escape prevention device ( 50) is to be stably fixedly coupled to the housing tube (31).

In addition, preferably, the separation prevention device 50 has a diameter from the outer periphery 55 toward the insertion tube 52 through the guide wall 54 connecting the outer periphery 55 and the insertion tube 52 . It is formed in the form of a funnel that becomes smaller, so that the handle bar 60 is guided to the guide wall 54 and inserted into the guide hole 51 .

In addition, preferably, the outer periphery 55 of the separation preventing device 50 is in close contact with the inner circumferential surface of the hollow 11 of the roller housing 12, and a plurality of close contact protrusions are placed on the outer circumferential surface of the outer periphery 55 at regular intervals. The piece 56 is formed to protrude, and the separation prevention tool 50 is configured to be in close contact with the inner circumferential surface of the hollow 11 through the close contact protrusion piece 56 . Here, the close contact protrusion piece 56 formed on the outer periphery 55 of the separation prevention device 50 is an entrance 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 contact portion 56b.

On the other hand, at least one end of both ends in the longitudinal direction of the sealing member 40 may form a guide inclined surface 43 whose end is inclined inward toward the rod fixing hole 41 . Preferably, the guide inclined surfaces 43 are formed at both ends of the sealing member 40 in the longitudinal direction, so that the sealing member 40 is inserted into the receiving tube 31 of the second stopper 30 in any direction, the same operation. to do In this way, the end of the sealing member 40 is formed as a guide inclined surface 43 , so that the handle rod 60 passing through the guide hole 51 of the separation preventing member 50 is guided simultaneously with the contact of the sealing member 40 . It is guided to the inclined surface 43 to be able to easily enter the rod fixing hole 41 .
