The present invention relates to a teaching aid for knot tying practice, the teaching aid enabling a user to easily practice tying various knots such as a knot needed in daily life or a knot for traditional crafts. The teaching aid for knot tying practice of the present invention comprises: a bottom plate (110); a string supporter (120) vertically coupled to as upper part of the bottom plate and having a string hanging groove (121) formed from the top thereof; fixing clips (130, 130a) fitted into the top of the string supporter to restrict the movement of a string hung on the string hanging groove; and an inclined supporter (140) coupled to an upper part of the bottom plate to support the string supporter.

TECHNICAL FIELD

The present disclosure relates to a teaching aid for knotting practice, which enables a user to easily practice tying various knots, such as a knot needed in daily life or a knot for traditional crafts.

BACKGROUND ART

In general, knots which intertwine various parts of one or more ropes, cords, or other flexible string vary widely in type, from simple knots necessary for daily life to traditional craft knots.

Such knots are widely used in everyday life. That is, for infants, knots serve as good developmental play for eye-hand coordination and fine motor skills. For the elderly, knots are effective for dementia prevention and strengthening of fine muscles. Moreover, knots are extensively used in various leisure activities such as camping, hiking, mountaineering, and fishing.

Therefore, there has always been a demand to learn various knotting techniques.

Recently, with the rising popularity of hobby activities like making traditional ornaments such as tassels and bracelets, there is an increasing trend in the demand to learn traditional craft knotting.

However, as knots become more complex, the number of strings, the direction in which the string moves, and the number of twists increase. Accordingly, significant attention is required when learning the knotting techniques. Due to the characteristics of strings used in knotting, since the strings are flexible and in a non-fixed state, the shape of the string changes unpredictably and frequently, and handling the string becomes difficult, so it is not easy to learn the knotting method.

For example, when practicing knotting by laying the strings on the floor, it is very difficult to pass a string between another string and the floor. This is because when one string is lifted, another string is inadvertently lifted, and it alters the shape and state of the knot. To prevent it, a user has to hold one string while lifting another, but in this case, since both hands become occupied, it is difficult to create further knots.

As described above, since it is very difficult to learn or teach the knotting method, there is a demand for improving the knotting method.

DISCLOSURE

Technical Problem

Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the related art, and it is an object of the present invention to provide a teaching aid for knotting practice which enables a user to easily handle strings and practice knotting.

Technical Solution

To accomplish the above-mentioned objects, according to the present invention, there is provided a teaching aid for knotting practice including: a bottom plate; a string supporter which is vertically co pled to an upper portion of the bottom plate and having a string hanging groove formed from the top thereof; a fixing clip which is fitted into the top of the string supporter to restrict the movement of a string hung on the string hanging groove; and an inclined supporter which is coupled to the upper portion of the bottom plate to support the string supporter.

Additionally, the string supporter is coupled to at least one of two sides of the bottom plate.

In addition, the string supporter has a strength-reinforcing rib formed in the vertical direction.

Moreover, the string supporter is detachably coupled to the bottom plate, and the bottom plate has a coupling groove formed therein to allow the bottom of the string supporter to be inserted.

Furthermore, the bottom plate has a string supporter storage groove formed therein in which the strength-reinforcing rib is inserted to store the string supporter when the string supporter is separated from the bottom plate.

Additionally, the inclined supporter is detachably coupled to the bottom plate, support protrusions are respectively formed on upper and lower portions of the inclined supporter, and one or more retaining grooves into which the support protrusions are respectively inserted are formed on the bottom plate and string supporter respectively.

Moreover, the inclined supporter has an insertion protrusion formed therein so that the inclined supporter can be stored by being fit into the retaining groove formed in the bottom plate when not in use.

In addition, the bottom plate has a fixing clip storage groove formed therein to store the fixing clip therein.

Advantageous Effect

Due to the string supporters provided on the upper portion of the bottom plate, since a user can practice knotting in a state in which the string needed for the knot is raised to a predetermined height from the bottom plate and is fixed in that position for practice, the teaching aid for knotting practice makes it easier to handle the string and facilitates knotting practice.

In addition, the present invention is configured in such a way that the components of the present invention can be inserted into the bottom plate, thereby providing convenience in carrying and preventing the loss of the components.

Hereinafter, referring to the drawings for a detailed explanation of the embodiments of the invention, the same components will be marked with the same symbols, and for clarity, primarily different parts will be explained.

FIG.1is a perspective view of a teaching aid for knotting practice according to an embodiment of the invention,FIG.2is an exploded perspective view ofFIG.1, andFIG.3is a side view of a used state ofFIG.1. As illustrated, the teaching aid for knotting practice of the invention includes a bottom plate110, string supporters120, fixing clips130and130a, and a inclined supporter140.

The bottom plate110is placed on a table during knot practice.

The string supporters120are vertically coupled to an upper portion of the bottom plate110. In the drawings, the string supporters120are coupled to both sides of the bottom plate110to face each other, but are not limited thereto, and may be coupled only to one side of the bottom plate110.

In the drawings, the string supporter120has a rectangular cross-section having the front surface facing the bottom plate110and the rear surface facing the side end of the bottom plate110, but is not limited thereto, and may have various cross-sectional shapes.

The string supporter120has a string hanging groove121formed at the upper portion thereof. A string used during knotting practice is placed on the upper end of the string supporter120through the string hanging groove121.

Each of the fixing clips130and130ais fit on the upper end of the string supporter120to restrict the movement of the string placed in the string hanging groove121.

A through-hole131through which the upper end of the string supporter120passes is formed in the center of each of the fixing clips130and130a. Since the string placed in the string hanging groove121must pass through the through-hole131, the through-hole131must be formed in a size to be spaced a predetermined distance from the string supporter120in consideration of the thickness of the string.

Therefore, when the string is fitted into the string hanging groove121and each of the fixing clips130and130ais fitted onto the upper end of the string supporter120, the upper end of the string supporter120and the string both pass through the through-hole131of each of the fixing clip130and130a. During the above process, the string is pressed against the front surface and the rear surface of the string supporter120, a path of the string is bent, and the movement of the string is severely restricted.

On the other hand, to maintain a constant contact pressure between the string supporter120and the string, an interval between the through-hole131and the string supporter120should vary depending on the thickness of the string.

That is, if the string is thin, the through-hole131is formed small, and if the string is thick, the through-hole131is formed large.

Therefore, the fixing clips130and130amay have different specifications depending on the size of the through-hole131.

Furthermore, it is preferable to form strength-reinforcing ribs122on the rear surface of the string supporter120in the vertical direction.

In this case, the strength-reinforcing ribs122are formed from a point spaced a predetermined distance from the top of the string supporter120to prevent interference with the fixing clips130and130afitted to the top of the string supporter120and extends to the bottom of the string supporter120.

The strength-reinforcing ribs122enhance the structural strength of the string supporter120and support the bottom of the fixing clips130and130a, thereby preventing the fixing clips130and130afrom sliding down along the string supporter120and releasing the string.

Meanwhile, for user convenience, the string supporter120can be detachably attached to the bottom plate110.

In this case, the bottom plate110has a coupling groove111into which the bottom of the string supporter120is inserted. In the case that the strength-reinforcing rib122is formed on the string supporter120, both the string supporter120and the strength-reinforcing rib122are inserted into the coupling groove111. In this instance, the coupling groove111is formed to tightly wrap around the bottom of the string supporter120and the strength-reinforcing rib122to prevent the movement of the string supporter120.

Furthermore, a point of the bottom plate110where the coupling groove111is formed can be raised higher than the surrounding area. In this case, the depth of the coupling groove111increases, and the bottom of the string supporter120is inserted more deeply into the coupling groove111.

Therefore, the coupling force between the string supporter120and the bottom plate110is doubled, and the string supporter120can maintain a more stable connection to the bottom plate110.

Meanwhile, it is preferable to form a string supporter storage groove113for the string supporter on the bottom plate110into which the strength-reinforcing rib122is inserted.

In this case, the string supporter120separated from the bottom plate110can be laid flat and stored in close contact with the bottom plate110, thereby making storage and organization of the string supporter120easier, enabling the user to carry it conveniently, and removing the risk of loss.

The inclined supporter140is coupled to the upper portion of the bottom plate110and supports the string supporter120.

The inclined supporter140supports the front side of the string supporter120.

Moreover, the inclined supporter140can be detachably combined with the bottom plate110.

In this case, support protrusions141are respectively formed on the top and the bottom of the inclined supporter140, and a plurality of retaining grooves112and123into which the support protrusions141are inserted are respectively formed on the bottom plate110and the string supporter120.

Furthermore, if the plurality of retaining grooves112and123are formed at regular intervals, it allows the user to change a support angle of the inclined supporter140according to the user's preference, thereby enhancing convenience in use.

On the other hand, preferably, the inclined supporter140includes insertion protrusions142to be fit into the retaining grooves112formed in the bottom plate110.

In this case, the inclined supporter140can be laid flat and stored in close contact with the bottom plate110, thereby making storage and organization of the inclined supporter140easier, enabling the user to carry it conveniently, and removing the risk of loss.

Furthermore, fixing clip storage recesses114for storing the fixing clips130and130acan be formed in the bottom plate110.

In this case, the fixing clips130and130aseparated from the string supporters120can be inserted and stored in the bottom plate110, thereby making storage and organization of the fixing clips130and130aeasier, enabling the user to carry them conveniently, and removing the risk of loss.

As described above, the teaching aid for knotting practice enables the user to hang a base string A, which is the base of a knot, on both of the string supporters120, tighten the string using the fixing clips130and130a, and make knots in various ways using different knot strings A1and A2.

Furthermore, because the base string (A) is fixed at a certain height from the bottom plate110without movement, handling the strings becomes easier and both hands are free, thereby making knot-practicing very convenient.

In addition, even if the string is pulled to create a knot, since the inclined supporter140robustly supports the string supporter120and the string supporter120has the strength reinforcing rib122formed on the string supporter120, the user can practice the knotting method in a stable state without the string supporter120bending or breaking.

As described above, when the user experiences making knots with other knot strings A1and A2in the condition that there is the base string A the teaching aid for knotting practice according to the present invention can be usefully utilized. Moreover, preferably, when packaging the teaching aid for knotting practice for sale, the base string A and the knot strings A1and A2can be packaged together in a set, thereby allowing users to easily experience immediately upon purchase.

As illustrated inFIG.4, when the user practices knotting methods that do not require the base string A, or in a case that the knotting process has advanced considerably and it is more convenient to work with the knotted ornament stretched out long, there is no need to install string supporters120on both sides of the bottom plate110. Instead, the string supporter120is installed on one side of the bottom plate110, the strings necessary for knotting are placed on the string hanging groove121, and then fix the strings with the fixing clips130and130ato practice knotting.

FIG.5illustrates a stored state of the teaching aid for knotting practice according to an embodiment of the invention. As illustrated in the drawing, after the knotting practice is finished, the fixing clips130and130aare separated from the string supporters120, and then, are stored and organized in the fixing clip storage recesses114of the bottom plate110. Subsequently, the string supporters120are separated from the bottom plate110, and then, the strength-reinforcing rib122is stored and organized in the string supporter storage groove113of the bottom plate110. Then, the insertion protrusion142of the inclined supporter140is stored and organized in the retaining groove112of the bottom plate110.

In this case, since the fixing clips130and130a, string supporters120, and the inclined supporter140are stored lying flat on the bottom plate110, the teaching aid for knotting practice does not occupy a large storage area, are neatly organized, are easy to carry, and has no risk of loss.

FIG.6is a cross-sectional view of a teaching aid for knotting practice according to another embodiment of the invention. As illustrated in the drawing, the string supporters120can be configured to be adjustable in height.

In this case, the string supporter120is divided into a lower body120aand an upper body120bwhich fits inside the lower body120a, wherein a threaded hole124in which a tightening screw125can be coupled can be formed in the upper body120b.

Therefore, the user can freely adjust the height of the string supporters120using the tightening screw125and fully engage in knotting practice.

Additionally, the coupling groove111formed in the bottom plate110may be formed in multiples at regular intervals along the side of the bottom plate110. In this case, the user can freely choose and adjust the position and spacing of the string supporters120according to the user's preference while doing knotting practice.

The exemplary embodiments of the present invention have been described in more detail with reference to the accompanying drawings, but the present invention is not limited to the exemplary embodiments, and may be variously modified and carried out within the scope of the technical spirit of the present invention, and the changes and modifications belong to the scope of the present invention.
