Abstract
Description
Technical Field
[0001] The present invention relates to a rake manufactured with elastic rake claws that can efficiently collect dust when cleaning the corners of stairs and when cleaning the corners under chairs fixedly installed in performance venues such as theaters or sports viewing facilities.
Background Art
[0002] To remove dust on the floor, a broom is used. Since it is difficult to remove wet fallen leaves, dust strongly attached to the floor surface, etc. with a general broom, cleaning is done by scraping with a rake in a state where the tip is bent.
[0003] Most of the rakes are made of synthetic resin materials or are made by combining rake claws made of bamboo materials. However, since each rake claw is fixed in one direction while maintaining a certain interval, there is a problem that it is difficult to scrape out even small dust.
[0004] To solve the above problems, Korean Utility Model Registration No. 20-0464968 (registered on January 21, 2013) "Broom with rake blades" (hereinafter referred to as "Patent Document 1") is known, and Korean Utility Model Publication Gazette (publication number: 20-2020-0001299, publication date: June 18, 2020) "Elastic broom in rake shape" (hereinafter referred to as "Patent Document 2") is known.
[0005] The broom 10 with rake blades described in "Patent Document 1" is, as shown in FIG. 1, a comb tooth 12 is coupled to a handle 11, and at least one or more rake blades 13 are included on the side where the comb tooth 12 is coupled. A separate rake blade 13 and a separate comb tooth 12 are coupled to one handle 11 so that the user can use the rake blade or the broom. However, when used as a rake, its function and effect are reduced when scraping large dust due to the comb teeth, and when used as a broom, there is a problem that the rake inhibits the function of the broom.
[0006] The rake-shaped elastic broom described in Patent Document 2 provides a rubber connecting part that imparts elasticity to the middle part of the broom brush and a bent broom brush that is bent into a rake shape to facilitate sweeping, enabling the user to sweep effectively. However, the rubber connecting part is in the form of a plate without a space part, resulting in a poor sweeping effect.

Summary of the Invention
Problems to be Solved by the Invention
[0008] The present invention aims to provide a rake that can simultaneously exhibit the functions of a rake and a broom when cleaning the corners of stairs, under the corners of chairs in performance venues or sports viewing facilities, and when sweeping up garbage such as fallen leaves on the lawn without damaging the lawn. To achieve this, the rake claws made of synthetic resin material forming the rake are extruded in the length direction while having an oval cross-section, and a plurality of ribs are protruded on the outer peripheral surface of the rake claws to be extruded when necessary, or a wave shape is continuously formed and then one side end is bent. By bending each rake claw at various angles, the intervals between the rake claws are made dense and irregular, providing a rake with excellent cleaning effect.
Means for Solving the Problems
[0009] In order to achieve the above object, the present invention improves the exposure strength and exposure life of the rake claws by forming the rake claws of a synthetic resin material forming a rake into an oval cross-section and extending them in the length direction.
[0010] And, a plurality of reinforcing ribs are projectingly provided along the length direction of the main body on the outer peripheral surface of the oval rake claws so as to reinforce the strength of the rake claws.
[0011] Also, the rake claws are formed such that waves are formed at regular intervals to further reinforce the strength of the rake claws.
[0012] Then, each rake blade of the rake claws bent from top to bottom is bent left and right when viewed in a plane, and by making these bending directions and angles different from each other, the intervals and maintenance angles between the respective rake blades are different from each other, and by installing the rake blades in multiple directions and at multiple angles, it is characterized in that it can be effectively swept regardless of the position where each piece of dust is located (for example, a plane or a corner), the type and size of the dust.
[0013] (Advantages of the Invention) The present invention as described above has the effect of making the rake claws oval, projectingly providing reinforcing ribs along the length direction of the rake claw body when necessary, and improving the exposure strength and exposure life of the rake claws.
[0014] Also, the rake claws can be linear, but by forming waves at regular intervals in the length direction, it has the effect of further reinforcing the strength of the rake claws.
[0015] Then, each rake blade of the rake claws bent from top to bottom is bent left and right when viewed in a plane, and by making these bending directions and angles different from each other, the intervals and positions between the respective rake blades are different from each other, and it has various effects that it can be effectively swept and collected regardless of the type, volume, weight, etc. of various types of dust and where they are located.

Modes for Carrying Out the Invention
[0017] Hereinafter, with reference to the accompanying drawings, embodiments of the present invention will be described in detail so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement them.
[0018] For each embodiment of the present invention, the specific structural and functional descriptions are merely illustrative for explaining the embodiments of the present invention. Each embodiment of the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described in the text.

However, this is not intended to limit the present invention to a specific disclosed form, and it should be understood that it includes all modifications, equivalents, and alternatives included in the spirit and technical scope of the present invention.
[0020] Terms such as "first" and "second" can be used to describe various components, but each of the above components should not be limited by the above terms. Each of the above terms can be used for the purpose of distinguishing one component from another.
[0021] The terms used in the present invention are merely for explaining specific embodiments and are not for limiting the present invention. Singular expressions include plural expressions unless the context clearly has a different meaning.
[0022] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention pertains. Each commonly used and pre-defined term should be construed to have a meaning consistent with the meaning in the context of the related art, and should not be construed in an ideal or overly formal sense unless clearly defined in the present invention.
[0023] Hereinafter, preferred embodiments will be presented to facilitate the understanding of the present invention. The following embodiments are merely provided to more easily understand the present invention, and it should be understood that the content of the present invention is not limited by the following embodiments, and there may be various variations that can replace them at the time of filing the present invention.
[0024] FIG. 2 is a perspective view illustrating the rake of the first embodiment of the present invention, FIG. 3 is a plan view illustrating the rake of the first embodiment of the present invention, FIG. 4 is a perspective view illustrating the rake of the second embodiment of the present invention, FIG. 5 is a plan view illustrating the rake of the second embodiment of the present invention, FIG. 6 is a perspective view illustrating the rake claw of the present invention, FIG. 7 is an enlarged perspective view illustrating a state in which a plurality of reinforcing ribs are protruding along the length direction on the outer peripheral surface of the rake claw body of the present invention, FIG. 8 is a side exemplary view showing that the rake formed at the terminal end of the rake claw of the present invention is bent at an obtuse angle, FIG. 9 is a plan exemplary view showing that the rake formed at the terminal end of the rake claw of the present invention is bent and bent in many directions in various ways, FIG. 10a is an explanatory view for showing that in a conventional rake, the terminal ends of the respective rake claws are installed while maintaining a constant interval, and FIG. 10b is an explanatory view exemplifying that the terminal ends of the rake claws of the present invention are bent and bent at various angles and are in a twisted state.
[0025] In the rake in which the other end portion of the rake claw 300 is fixed by a method such as fusion inside the rake claw fixing housing 200 connected to the handle 100 according to the present invention, as the rake claw body 310 made of a synthetic resin material, an extruded one having an oval cross-section in a straight form or one in which waves 311 are continuously formed at regular intervals is used.
[0026] Then, as shown in FIG. 7, a plurality of reinforcing ribs 312 are continuously protruded along the length direction on the outer peripheral surface of the rake claw body 310, and the strength of the rake claw body 310 can be improved.
[0027] It is determined that the number of the reinforcing ribs 312 is preferably 3 to 8.
[0028] On one side, at one end of the rake claw body 310 (the side opposite to the rake claw fixing housing), rake blades 320 with different bending angles (α) bent from top to bottom and different bending angles (β) bent in the left - right direction when viewed in a plane are bundled at different intervals and maintenance angles respectively, and each rake blade 320 is installed in a state of being intertwined in multiple directions and at multiple angles. By doing so, each rake blade 320 can effectively sweep in places where there are various types of garbage 400 (for example, the floor surface is uneven ground, corners such as under chairs, grassy fields with thick grass, etc.), regardless of the type and size of the garbage. This is the characteristic of the present invention.
[0029] In the present invention as described above, the reason for extending the rake claw body 310 in an oval shape for use is to improve the disclosure strength or disclosure life compared to the rake claws formed in a circular shape.
[0030] Also, as shown in FIGS. 2 and 3, for each rake blade 320, only one first rake blade 321 can be installed at the terminal end of the rake claw. As shown in FIGS. 4 and 5, a second rake blade 322 can also be installed together with the first rake blade 321 at a location separated by a certain distance from the terminal end of the first rake blade 321.
[0031] Naturally, a third rake blade (not shown) can be installed in the same way.
[0032] And when the first rake blade 321 is installed such that the bending angle (α) bent from top to bottom at the terminal end of the first rake blade 321 is not the same and is bent diversely within an obtuse - angle range of about 95° to 175°, when scraping up garbage or sweeping up garbage with the rake blade, the use effect can be doubled. Naturally, the second rake blade 322 and the third rake blade (not shown) can also be used by being bent together with the first rake blade 321.
[0033] On the one hand, as shown in FIG. 3, the first rake blade 321 is not formed linearly when viewed in a plane. When the first rake blade 321 is bent in the left - right direction and the bending angle (β) is diversified, as shown in FIG. 10b, the first rake blades 321 are bundled in a twisted state at different intervals and maintaining angles. During cleaning, each rake claw having its own elasticity can effectively contact the floor surface and the gaps due to the elastic force of each rake claw itself with the dust on the bent floor surface, the dust in narrow gaps, and the dust in the corners being twisted. Thus, it can have various effects during cleaning, and the second rake blade 322 and the third rake blade can also be bent in the same way and used.
[0034] As described above, there can be many types of methods for forming the bending angle (α) and the bending angle (β) at one - side ends of the first and second rake blades 321, 322. However, the applicant of the present application used a method of applying heat while bending one - side ends of the rake blades using a jig to cause plastic deformation.
[0035] The present invention having the above - described configuration is made of a synthetic resin material. Since each rake claw having its own elastic force has its respective bending angle (α) and bending angle (β), when these are bundled, the space in which the rake claws are bundled while being twisted is very narrow, and they can move freely and flexibly. Thus, it becomes easy for each rake claw to enter narrow spaces where dust is located, corners, floor surfaces with severe bending, and places where the gaps are not wide. It will be able to sweep the dust attached to the floor (such as wet paper and fallen leaves) and fine dust such as cigarette butts located in the gaps at the corners in a state of scraping and collecting them.
[0036] And when cleaning the lawn (including artificial lawn) after mowing the lawn, each rake blade bundled in a twisted state at various angles does not damage the lawn and the artificial lawn, and has the effect of being able to clean the dust in the gaps such as the mowed lawn well.
[0037] Also, when the second rake blade 322 is installed at a position slightly separated from the first rake blade 321 for each rake blade, it is fully predictable that the cleaning effect will be even better.
[0038] Above, the embodiments of the present invention have been described with reference to the accompanying drawings. However, those having ordinary knowledge in the technical field to which the present invention pertains will be able to understand that it can be implemented in other specific forms without changing the technical idea and essential features.
[0039] Therefore, it must be understood that the embodiments described above are illustrative in all respects and not restrictive. The scope of the present invention described in the above detailed description is indicated by the claims, and it should be interpreted that the meaning and scope of the claims, and all changes or deformations derived from the equivalent concepts thereof are included in the scope of the present invention.
