Description

Sweeping broom with replaceable bristles

The present invention relates to a cleaning broom with replaceable comb teeth.

The cleaning broom is a tool that has been with us for a long time. When we sweep the yard or clear the snow, we use a sweeping broom.

The composition of the cleaning broom is simple. The cleaning broom is composed of a handle part that can be held by hand, a comb part composed of a plurality of comb teeth, and a connection part for connecting the comb part and the handle part.

Brooms for cleaning using plastic are easy to manufacture and have the advantage of being durable. For this reason, the use of cleaning brooms using plastic cleaning brooms, which conventionally used tree branches or plant stems, has increased.

However, plastics do not rot for a long time in nature and become the main cause of destroying the environment. In order to solve environmental problems, it is necessary to reduce the use of plastics. However, eco-friendly combs wear out and break easily compared to plastic combs, so durability is not good. That is, a cleaning broom using eco-friendly comb teeth has a shorter lifespan than a cleaning broom using plastic comb teeth. If the eco-friendly bristles break, you will have to buy a new sweeping broom, even if there are no problems with the broom handle and connections.

In order to reduce the use of plastics that cause environmental problems in cleaning brooms, Patent Registration No. 10-1875096 proposed a broom using eco-friendly combs such as twig combs or plant stem combs. However, in Patent Registration No. 10-1875096, an adhesive is used to fix the teeth of the comb. That is, even with the cleaning broom proposed in Patent Registration No. 10-1875096, if the comb is broken, there is a problem in that the entire cleaning broom must be newly purchased even if there is no problem with the broom and the connecting portion of the cleaning broom.

Therefore, there is a need for a new cleaning broom that can solve these problems.

One object of the present invention is to use an eco-friendly comb, but to provide a cleaning broom in which the user can easily replace the eco-friendly comb.

Meanwhile, other unspecified objects of the present invention will be additionally considered within the scope that can be easily inferred from the following detailed description and effects thereof.

A cleaning broom according to an embodiment of the present invention for solving the problems described above includes a handle that can be held by hand, a comb part composed of a plurality of comb teeth, and a connecting part connecting the handle and the comb. And, the connection part includes a first housing having a receiving part having one side opened therein; and a second housing inserted into the accommodating portion, wherein the comb portion is inserted into an insertion space formed by an inner wall of the first housing and an outer wall of the second housing, and the inner wall of the first housing and the outer wall of the second housing. It is characterized in that the comb portion inserted into the insertion space is pressed and fixed as the two housings come closer to each other.

In one example, a plurality of comb teeth constituting the comb portion may be characterized in that they are tied to each other by a connection band or a connection string.

In one example, when the comb portion is inserted into the insertion space, at least a portion of the connection band or the connection string is inserted into the insertion space, so that the inner wall of the first housing and the outer wall of the second housing come closer to each other. Accordingly, at least a portion of the connection band or the connection string inserted into the insertion space may be pressed.

In one example, a coating layer for increasing frictional force or a protrusion for pressing the comb portion may be formed on an inner surface of the first housing or an outer surface of the second housing.

In one example, a connecting rod is formed in the second housing to penetrate the first housing and is coupled to the handle, and a thread is formed on an outer surface of the connecting rod so that the first housing is screwed to the connecting rod. can be done with

In one example, it may be characterized in that it further comprises a coupling screw that penetrates the first housing and the second housing and is screwed into a coupling hole located at one end of the handle.

In one example, the comb portion may be characterized in that it is an eco-friendly comb formed by using a tree branch or a plant stem.

A cleaning broom according to another embodiment of the present invention for solving the problems described above includes a handle that can be held by hand, a comb part composed of a plurality of comb teeth, and a connecting part connecting the handle and the comb part. And, the connecting portion includes a first housing formed with a first receiving portion having one side opened therein; at least one connection housing inserted into the first housing and formed with a second accommodating part having one side opened therein; and a second housing inserted into the second accommodating part, including an insertion space formed by an inner wall of the first housing and an outer wall of the connection housing, by an inner wall of the connection housing and an outer wall of the second housing. The comb part is inserted into the insertion space formed and the insertion space formed by the inner wall of one connection housing and the outer wall of the other connection housing, and as the inner wall and the outer wall constituting the insertion space come closer to each other, the It is characterized in that the comb part inserted into the insertion space is pressed and fixed.

In the cleaning broom according to an embodiment of the present invention, when the eco-friendly comb is worn out or broken during use by the user, it can be easily replaced with a new eco-friendly comb. That is, since the comb teeth can be replaced according to an embodiment of the present invention, there is no need to buy a new cleaning broom even though there is no problem with the broom and the connecting portion.

It is added that even if the effects are not explicitly mentioned here, the effects described in the following specification expected by the technical features of the present invention and their provisional effects are treated as described in the specification of the present invention.

It is revealed that the accompanying drawings are illustrated as references for understanding the technical idea of the present invention, and thereby the scope of the present invention is not limited thereto.

Hereinafter, with reference to the drawings, look at the configuration of the present invention guided by various embodiments of the present invention and the effects resulting from the configuration. In the description of the present invention, if it is determined that a related known function may unnecessarily obscure the subject matter of the present invention as an obvious matter to those skilled in the art, the detailed description thereof will be omitted.

The cleaning broom 100 according to an embodiment of the present invention includes a handle part 10 that can be held by hand, a comb part 50 composed of a plurality of comb teeth, the handle part 10 and the comb part ( 50) and a connection part 20 connecting them.

The handle portion 10 is a rod formed long in one direction, and wood is used in the present invention. The length of the handle portion 10 may vary depending on the use. In the case of outdoor use such as a road, yard, plaza, etc., the handle is formed long, but in the case of indoor use, it is formed relatively short to the height of a person's waist.

The comb part 50 is a part that sweeps an object to be cleaned and has a structure in which a plurality of comb teeth form a bundle. The comb has a length of several tens of cm and a thickness of several mm, and is formed thin and long. In the present invention, an eco-friendly comb formed using a tree branch or a plant stem can be used as the comb.

In particular, it is characterized in that coconut palm twigs are used as combs in the present invention. There are three advantages to using coconut palm twigs.

First, coconut palm branches are eco-friendly. If you use a plastic comb as a comb for a cleaning broom, you can easily and comfortably manufacture a cleaning broom. However, plastic combs cause environmental pollution. Coconut palm twigs are not only eco-friendly, but also have greater elasticity than other materials, so it is possible to easily and conveniently manufacture a broom for cleaning by the unique fastening structure of the present invention.

Second, coconut wood is suitable for use as a comb due to its high abrasion resistance compared to other types of wood. In other words, in the case of clover tree or bamboo material, strength and wear resistance are low, and when used for a certain period of time, the part in contact with the ground wears out quickly, resulting in a short service life. However, coconut wood has high wear resistance and can be used for a sufficiently long period.

Thirdly, as described above, the coconut tree has excellent elasticity compared to other trees. Comb teeth used in cleaning brooms must be able to maintain a certain level of elastic tension while being well bent. That is, when the user presses the cleaning broom in contact with the ground, the comb teeth are bent and the contact area with the ground is widened, and since the comb teeth press the ground by elastic force in a pressurized state, the object to be treated can be well swept. However, if the strength of the comb teeth is too strong, it does not bend well and resists, so it is difficult to clean and the cleaning efficiency is reduced. Coconut wood material has the optimal conditions for comb teeth in terms of abrasion resistance and elasticity.

In addition, since coconut trees are widely cultivated in Southeast Asia, such as the Philippines and Indonesia, they have the advantage of being economically available compared to plastics as well as bamboo and bush clover. The above advantages are the reasons for using the coconut tree material as the comb in the present invention.

However, even if coconut palm twigs are used as combs, eco-friendly combs lack durability and have a shorter lifespan than plastic combs.

Accordingly, the cleaning broom 100 of the present invention is configured so that the user can easily replace the comb part 50.

To this end, the connection unit 20 includes a first housing 21 and a second housing 22 . The connecting portion 20 may be formed of a wooden material. Alternatively, recycling may be induced by forming the connecting portion 20 with a metal material.

The first housing 21 has a receiving portion having one side opened therein. The first housing 21 may have the shape of a truncated cone whose diameter gradually increases in the opening direction. For example, the first housing 21 may have a “cup” shape.

The second housing 22 is inserted into the receiving portion of the first housing 21 . The second housing 21 may have a shape corresponding to the accommodating portion of the first housing 21 .

When the second housing 22 is inserted into the accommodating part of the first housing 21, an insertion space is formed by the inner wall of the first housing 21 and the outer wall of the second housing 22.

The comb portion 50 is inserted into the insertion space. When the inner wall of the first housing 21 and the outer wall of the second housing 22 come close to each other, the comb 50 inserted into the insertion space is pressed.

In particular, the second housing 22 of the cleaning broom 100 according to an embodiment of the present invention has a connecting rod 23 that penetrates the first housing 21 and is coupled to the handle 10. The handle 10 is fitted to the end of the connecting rod 23, and a thread 24 is formed on the outer surface of the connecting rod 23. The end of the connecting rod 23 has a cutout portion in which a diameter is extended to the handle portion 10 . When the handle 10 is inserted into the end of the connecting rod 23, the handle fixing nut 26 is coupled to the thread formed in the cutout so that the cutout presses the handle 10.

The first housing 21 may be screwed to the connecting rod through the thread 24, or the first housing 21 may be pressed toward the second housing 22 using the first housing fixing nut 25. In addition, as the first housing 21 is deeply coupled in the direction of the second housing 22, the inner wall of the first housing 21 and the outer wall of the second housing 22 come closer, and accordingly, the comb part 50 It is fixed more firmly in the insertion space.

FIG. 4 is a schematic reference view showing an unfolded comb part of a cleaning broom according to an embodiment of the present invention, and FIG. 5 shows a rolled-up comb part of a cleaning broom according to an embodiment of the present invention. It is a schematic reference diagram.

The purpose of the cleaning broom of the present invention is to enable the user to easily replace the eco-friendly comb. However, when the comb teeth are inserted into the insertion space one by one, it is difficult to achieve the above object of the present invention. In addition, even if the comb part 50 is replaced by inserting the comb teeth one by one into the insertion space, since the size of the comb teeth of the eco-friendly comb is not constant, there is a high possibility that the comb teeth easily fall out of the insertion space during use of the cleaning broom.

In the cleaning broom of the present invention, a plurality of comb teeth are tied together by a connecting band or a connecting string 51 so that the user can easily replace the comb part 50 . As the connection band, an elastic material such as a rubber band may be used, or a cloth woven with silk thread to have elasticity may be used. An elastic material such as a rubber band or silk thread may be used as a connecting string.

As described above, since the cleaning broom of the present invention has a plurality of comb teeth tied together by a connecting band or a connecting string 51, the user inserts the comb part 50 into the insertion space at once and removes the first housing 21. The comb portion 50 may be fixed by bringing the inner wall and the outer wall of the second housing 22 closer together.

In particular, when the comb portion 50 is inserted into the insertion space, at least a portion of the connection band or the connection string 51 may be inserted into the insertion space. That is, when the inner wall of the first housing 21 and the outer wall of the second housing 22 come close to each other, at least a part of the connecting band or connecting string 51 inserted into the insertion space is pressed, so that the eco-friendly comb has the size of the comb. It is possible to prevent the problem that the bristles easily fall out of the insertion space during use of the cleaning broom due to unevenness.

It is preferable that the length L when the comb portion 50 is unfolded is twice or more than the diameter of the end of the outer wall of the second housing 22 . In this way, the length L of the comb portion 50 when it is spread is set to be twice or more than the diameter of the end of the outer wall of the second housing 22, so that the comb teeth are more densely arranged.

On the other hand, when the comb portion 50 is rolled as shown in FIG. 5, there is an advantage in that it is easy to store and transport.

6 and 7 are schematic enlarged views of part A of FIG. 3 .

As described above, since the size of the comb teeth of the eco-friendly comb is not constant, there is a high possibility that the comb teeth easily fall out of the insertion space while the cleaning broom is in use. Therefore, in the cleaning broom of the present invention, a coating layer C1 for increasing frictional force is formed on the inner surface of the first housing 21 or the outer surface of the second housing 22, or the projections C2 pressing the comb part 50 are formed. is formed The coating layer (C1) may be a rubber coating or a silicone coating. Meanwhile, when the comb part 50 includes the connecting band or the connecting string 51, the coating layer C1 or the protrusion C2 may press the connecting band or the connecting string 51.

Among the configurations of the cleaning broom 200 of another embodiment, a description of the same components as the cleaning broom 100 of one embodiment will be omitted.

The connection part 20 of the cleaning broom 200 according to another embodiment of the present invention is inserted into the first housing 21 and the first housing 21 formed with a first accommodating part having one side opened on the inside, and one side on the inside It includes at least one connection housing 25 in which the second accommodating part is formed and the second housing 22 inserted into the second accommodating part.

At this time, the insertion space formed by the inner wall of the first housing 21 and the outer wall of the connection housing 25, the insertion space formed by the inner wall of the connection housing 25 and the outer wall of the second housing 22, and The comb part 50 is inserted into the insertion space formed by the inner wall of one connection housing 25 and the outer wall of the other connection housing 25, and is inserted as the inner and outer walls constituting the insertion space come closer to each other. The comb portion 50 inserted into the space is pressed and fixed.

That is, in the cleaning broom according to another embodiment of the present invention, two or more insertion spaces having different diameters are formed by the connection housing 250, and the comb part 50 is formed in the two or more insertion spaces having different diameters. By being inserted, the teeth of the cleaning broom become more dense.

Among the configurations of the cleaning broom 300 of another embodiment, descriptions of the same components as those of the cleaning broom 100 of one embodiment will be omitted.

Another embodiment of the cleaning broom 300 includes a coupling screw 60 that penetrates the first housing 21' and the second housing 22' and is screwed into a coupling hole located at one end of the handle 10'. more includes

When the coupling screw 60 is tightened, the inner wall and the outer wall constituting the insertion space come closer to each other, and accordingly, the comb inserted into the insertion space is pressed and fixed.

The various embodiments of the present invention described above can be used together with each other to the extent that they are not excluded. In addition, the protection scope of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is added once again that the scope of protection of the present invention cannot be limited due to obvious changes or substitutions in the technical field to which the present invention belongs.
