Description

A rake made of elastic rake ribs

[0001] The present invention relates to a rake manufactured with elastic ribs that can efficiently collect trash when cleaning the corners of stairs and the corners under seats installed in performance halls such as theaters or sports viewing facilities.

[0002] To remove trash on the floor, a broom is used, and for wet fallen leaves and trash that is strongly stuck to the floor, it is difficult to remove with a regular broom, so a rake with a curved tip is used to clean.

[0003] The rakes mentioned above are mostly made of synthetic resin or made by weaving together bamboo ribs. However, these had the problem that it was difficult to scrape away even small-volume trash because the ribs were fixed in one direction while maintaining a certain interval.

[0004] To solve the above-mentioned problem, domestic utility model registration No. 20-0464968 (registered on January 21, 2013) "Broom with a raked blade" (hereinafter referred to as "Patent Document 1") is known, and domestic utility model publication (publication number: 20-2020-0001299, publication date: June 18, 2020) "Elastic broom in the shape of a rake" (hereinafter referred to as "Patent Document 2") is also known.

[0005] The broom (10) having a blade disclosed in 'Patent Document 1' includes, as shown in FIG. 1, comb teeth (12) coupled to a handle (11) and at least one blade (13) on the side where the comb teeth (12) are coupled, and a separate rake blade (13) and a separate comb teeth (12) are coupled to one handle (11) so that a user can use the rake blade or the broom. However, when used as a rake, the function and effect are lowered when collecting bulky trash due to the comb teeth, and when used as a broom, the rake hinders the function of the broom.

[0006] The rake-shaped elastic broom described in 'Patent Document 2' provides a rubber connecting part that provides elasticity to the middle part of the broom brush and a curved broom brush that is good for sweeping by being bent into a rake shape, thereby enabling the user to clean effectively. However, since the rubber connecting part is in the form of a plate without a space, the cleaning effect is not good.

[0011] The present invention provides a rake having an excellent cleaning effect, in which the cross-section of synthetic resin ribs forming the rake is formed into an oblong shape and is extruded in the longitudinal direction, and a plurality of ribs are protruded on the outer surface of the extruded ribs or are formed in a continuous wave shape, and then one end is bent, and the angles of the bent ribs are bent at various angles so that the intervals between the ribs are dense and irregular, thereby enabling the rake to have the functions of both a rake and a broom at the same time when cleaning the corners of stairs and the corners under the seats of a performance hall or sports facility, and when sweeping up trash such as fallen leaves on the lawn without damaging the lawn.

[0012] In order to achieve the above purpose, the present invention has made it possible to improve the fatigue strength and fatigue life of a synthetic resin rake rib forming a rake by stretching the rake rib in the longitudinal direction so that the cross section is an oblong shape.

[0013] And on the outer surface of the oval-shaped rake, multiple reinforcing ribs are placed along the length of the main body to reinforce the strength of the rake.

[0014] Additionally, the strength of the rake is further reinforced by forming waves at regular intervals.

[0015] And the rake blades of the rake that bend from top to bottom are bent to the left and right when viewed from a flat surface, but the bending direction and angle of these are each different, so that the gap and the maintenance angle between the rake blades are each different, so that the rake blades are installed in various directions and various angles, so that cleaning can be done effectively regardless of the location (e.g., flat surface or corner, etc.) and type and size of the trash when cleaning.

[0016] The present invention described above has the effect of improving the fatigue strength and fatigue life of the rake rib by forming the rake rib into an oblong shape and, if necessary, by protruding reinforcing ribs along the length of the rake rib body.

[0017] Additionally, the rake can be made in a straight line, but the strength of the rake is further enhanced by forming waves at regular intervals in the length direction.

[0018] And the rake blades of the rake that bend from top to bottom are bent to the left and right when viewed from a flat surface, but the bending direction and angle of these are each different, so that the gap and position between the rake blades are each different, so that many types of garbage can be effectively collected regardless of the type, volume, or weight of the garbage, no matter where it is located, and there are various effects.

Therefore, it should be understood that various modifications may be substituted for these examples at the time of filing of the present invention.

This is an illustration showing that the ends of the rake ribs are bent and banded at various angles, creating a tangled and tangled state.

[0048] The present invention relates to a rake in which the other end of a rake rib (300) is fixed to the inside of a rake rib fixing housing (200) connected to a handle (100) by a method such as fusion, and the rake rib body (310) made of synthetic resin is extruded in a straight line with a cross-section in an oblong shape or has waves (311) continuously formed at regular intervals.

[0049] And, as shown in Fig. 7, on the outer surface of the above-mentioned rake body (310), a plurality of reinforcing ribs (312) can be continuously protruded along the longitudinal direction to improve the strength of the rake body (310).

[0050] In the above, it is determined that 3 to 8 reinforcing ribs (312) are desirable.

[0051] Meanwhile, on one end of the rake main body (310) (the opposite side of the rake fixing housing), rake blades (320) having different bending angles (α) for bending downwards and bending angles (β) for bending left and right when viewed from the plane are connected at different intervals and maintaining angles so that the rake blades (320) are installed in a tangled manner in various directions and angles, thereby effectively cleaning a place where various types of trash (400) are present (for example, a ground with an uneven surface, a corner such as the bottom of a chair, a field with lush grass, etc.) and regardless of the type and size of the trash.

[0052] The reason why the rake body (310) in the present invention described above is used by extending it into an oblong shape is to improve fatigue strength or fatigue life compared to rake ribs formed in a circular shape.

[0053] In addition, the rake blades (320) can be installed only with the first rake blade (321) at the end of the rake rib as in FIGS. 2 and 3, and the second rake blade (322) can be installed together with the first rake blade (321) at a certain distance from the end of the first rake blade (321) as in FIGS. 4 and 5.

[0054] Of course, you can install the third prong (no city) in the same way.

[0055] And, in the case where the bending angle (α) of the tip of the first rake blade (321) is not the same as above, but is bent in various ways within an obtuse angle range of about 95° to 175°, when the first rake blade (321) is installed, the usability can be doubled when collecting or sweeping trash with the rake blade, and of course, the second rake blade (322) or the third rake blade (not shown) can also be used by being bent like the first rake blade (321).

[0056] Meanwhile, the first rake blade (321) is not formed in a straight line when viewed from the plane as in FIG. 3, but is bent in the left and right directions so that the bending angle (β) of the first rake blade (321) is varied, so that the intervals and maintenance angles of the first rake blade (321) are each entangled and tied in different ways as in FIG. 10b, so that when cleaning, the rake teeth, which have elasticity in themselves, effectively come into contact with the floor surface and the gaps due to the elasticity of the entangled rake teeth, such as trash on a curved floor surface, trash in a narrow gap, and trash in a corner, thereby providing various effects when cleaning, and the second rake blade (322) and the third rake blade can also be used by bending in the same way.

[0057] As described above, there are various methods for forming a bending angle (α) and a bending angle (β) at one end of the first and second prongs (321) (322), but the applicant of the present invention used a method of applying heat while bending one end of the prongs using a jig to cause plastic deformation.

[0058] The present invention having the above-described configuration has rakes made of synthetic resin material and having elasticity of their own, each having a bending angle (α) and a bending angle (β), so that when these are connected, the rakes are entangled and can move freely and smoothly in a very narrow space between the connected rakes, so that the rakes can easily enter narrow spaces, corners, floors with severe curves, and places with narrow gaps where trash is located, so that when cleaning, the cleaning is done in a state where trash (wet paper, fallen leaves, etc.) attached to the floor and small trash such as cigarette butts located in corners and gaps are raked and collected.

[0059] And, when cleaning the lawn (including artificial grass) after mowing, the raking blades, which are entangled and connected at various angles, are effective in cleaning up debris in the gaps between the mowed grass and artificial grass without damaging the grass or artificial grass.

[0060] Additionally, it can be reasonably expected that the cleaning effect will be improved if the second rake blade (322) is installed at a position slightly away from the first rake blade (321).

[0061] Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features.

[0062] Therefore, the embodiments described above should be understood as being exemplary in all respects and not restrictive, and the scope of the present invention described in the detailed description above is indicated by the claims, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
