Description

Folding mast apparatus < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a folding mast apparatus, and more particularly, to a folding mast apparatus having a foldable mast that can be folded and improved in terms of transportation / storage and maintenance of a vessel.

Generally, a ship is a structure that floats above the surface of water and can be loaded with people or materials, and is largely provided with a hull, a mast, and a sail.

Here, the mast is a column vertically erected on a deck on the center line of the hull, and is usually referred to as a mast. Such a mast is used as a pillar for sailing, and is classified into a single mast, a bipod mast, a tripod mast, etc. Currently, it is mainly used for leisure sailing yachts .

On the other hand, due to the proliferation of leisure culture and the regional characteristics surrounding the three sides of the sea, interest in small leisure vessels such as sailing yachts has increased as the marine sports population has increased. to be. At this time, the small ship is provided with a separate motor so that it can run on the water surface by the driving force of the motor, but can be driven by the wind force applied to the sail connected to the mast.

In detail, Fig. 1 is a schematic view showing a conventional sailing yacht. As shown in FIG. 1, the conventional sailing yacht 1 fixes the mast m at a suitable position on the upper surface of the ship h. The sail (s) is attached to the mast (m), and the yacht (1) travels while centering the mast (m). Thus, the mast m is a very important factor in a ship running on the wind using a wind power such as a yacht.

However, in the conventional yacht 1, the length of the mast m fixed to the upper surface of the hull h is generally longer than the length of the hull h and has a heavy weight, As shown in FIG.

As a result, transportation and storage on land is practically difficult, so it is common to keep them at sea level. However, such maritime mooring has a problem that it is economically burdensome for many people to own a yacht because it requires excessive mooring cost compared with land mooring.

In addition, there is a problem that damage to the outer surface of the hull is caused by attachment of seaweeds and shellfish to the bottom of the ship which is submerged in water during marine mooring. Furthermore, since the repair work for repairing the damaged outer surface of the hull is troublesome and is still stored in the marine state even after repairing, excessive life span due to repetitive repair work of the hull and deterioration of the durability of the hull, There was a problem that this was shortened.

Furthermore, the hull collides against the adjacent hull or structure due to the storm surge resulting from deterioration of the weather during maritime mooring, which is also problematic.

As shown in FIGS. 2 to 4B, the folding mast apparatus 100 according to the present invention extends vertically upwardly to one side of the hull h of a ship 2 that travels along the water surface using wind power, such as a sailing yacht. At this time, the foldable mast device 100 is preferably provided with a mast base 10, a mast frame 20 and a hinge rotation part 30 connected to a sail s along the longitudinal direction. Do.

It is preferable that the mast base 10 is provided at a predetermined height on one side of the bottom surface of the hull h and a fixing groove 11 opened upward in the inside of the protruded body is formed . At this time, the mast base unit 10 may be integrally formed at the time of manufacturing the hull h, and the mast base unit 10 manufactured separately may be fixed to the hull h.

The fixing groove portion 11 is formed at one end of the mast frame portion 20 so that the one end portion 21 of the mast frame portion 20 is selectively inserted and fixed so as to stand upright in the vertical direction of the hull h. It is preferable to provide a groove having a shape corresponding to the shape of the portion 21. Accordingly, the one end portion 21 of the mast frame portion 20 can be prevented from being swung due to wind or external impact while being inserted / fixed in the fixed groove portion 11. [

In addition, the mast frame part 20 is provided in a bar shape extending in the longitudinal direction, and the sails s are connected. At this time, although not shown in the drawing, the sail (s) and the fuller (s) wound on the rope, which is provided for spreading or folding the sail (s), are provided at one end 21 and the other end of the mast frame portion 20 ) May be further provided.

The mast frame part 20 includes a pair of frame bars 20a with one side facing each other and a fastening member 20f for integrally connecting the pair of frame bars 20a. .

Specifically, it is preferable that the frame bar 20a is formed by extending a high-strength material in the longitudinal direction so that the flat portion 20b is formed on one side of the longitudinal direction.

Here, the high-strength material is preferably a curable high-strength synthetic resin material such as a fiber-reinforced plastic or a phenol resin, or an iron or non-ferrous metal material.

Particularly, since the curable high strength synthetic resin material is light in weight, easy to process, and maintained in strength, the economical efficiency can be remarkably improved. In addition, since the corrosion resistance and salt resistance of the water and chemicals are excellent, the durability against the fresh water or sea water environment in which the ship is mainly driven can be remarkably improved. Of course, the frame bar may be manufactured using a light metal material such as aluminum, or the frame bar may be manufactured using a high-strength material of various materials used for manufacturing parts of a ship.

Particularly, in the case of the bar shape as described above, a mold corresponding to the cross-sectional shape of the frame bar 20a is manufactured and drawn or extruded, so that it can be easily manufactured into a rod or a tube having a desired cross-section. Further, since the required length can be easily cut and then left and right can be assembled symmetrically, productivity and facility can be remarkably improved. Of course, the frame bar 20a may be injected into a predetermined mold, injection-molded, cut or bent, and such a manufacturing method may be easily carried out by those skilled in the art. It is omitted.

The pair of frame bars 20a having the flat surface portion 20b formed on one side as described above are integrally formed using the fastening member 20f in a state in which the flat portion 20b is in close contact . In this case, the outer surface of the frame bar 20a is rounded to be semi-elliptical in the drawing, but may be formed in various shapes such as a rectangular or polygonal shape. That is, the outer surfaces of the pair of frame bars 20a, which are symmetrical with respect to each other as the flat portion 20b is in close contact with each other, may have a circular shape, an oval shape, a rectangular shape, or a polygonal shape.

The lengthwise direction of the flat portion 20b is set to be equal to the length of the flat portion 20b so that the receiving grooves e1 and e2 are formed on the inner side in a state where the pair of frame bars 20a are integrally fastened using the fastening member 20f It is preferable that at least one depression 20c or 20d is formed.

Accordingly, since the pair of frame bars 20a can be easily assembled into the mast frame part 20, the manufacturing can be remarkably improved.

At this time, the receiving groove portions e1 and e2 may receive the sail s and a rope capable of folding or unfolding the sail s. For example, the sail s can be folded in the opening receiving groove portion e1 having the opening c formed at one side of the frame bar 20a and accommodated through the opening c. Accordingly, since the sail (s) is not required to be stored in a separate storage device, the storage property can be remarkably improved. Since the sail s can be stored substantially integrally with the mast device 100, the user can easily find and use the sail s and prevent the loss of parts such as the sail s.

In addition, the hollow receiving groove portion e2 may receive the rope. Accordingly, the rope can be prevented from being entangled due to external factors such as wind or the like, so that stability and ease of use can be remarkably improved. Moreover, since the pair of frame bars 20a are separated easily by separating the fastening member 20f, it is easy to replace or repair the rope housed therein.

Through this, an opening-receiving recessed portion e1 may be formed on one side of the mast frame portion 20 in the longitudinal direction, and a hollow receiving recessed portion e2 may be formed on the other side of the masted frame portion 20 in the longitudinal direction. Of course, the depressions 20c and 20d may be formed by a plurality of depressions 20c, and these modifications fall within the scope of the present invention.

Meanwhile, it is preferable that the hinge rotation part 30 is provided at the upper end of the mast base part 10. The hinge rotation part 30 may be provided on the opening edge of the fixing groove part 11. The hinge rotation part 30 may include a hinge slot hole 22 formed at one end 21 of the mast frame part 20, It is preferable that the hinge shaft 31 is provided.

The hinge shaft 31 of the hinge rotation part 30 and the hinge slot hole 22 of the hinge rotation part 30 are substantially in a state in which the one end 21 of the mast frame part 20 is inserted into the fixing groove part 11. [ And may be located on the corresponding movement path line. Both end portions of the hinge shaft 31 can be restrained between the pair of hinge rotation portions 30. The mast frame portion 20 to be hinged with the hinge shaft 31 is also supported by the pair of hinge rotation portions 30, And can be restrained between the rotation portions 30. Accordingly, even if the one end portion 21 is separated from the fixing groove portion 11 in order to rotate and fold the mast frame portion 20, the state of being substantially connected to the mast base portion 10 can be maintained. Thus, it is possible to prevent the components such as the sail (s) received in the mast frame portion 20 and the mast frame portion 20 from being lost.

One end 21 of the mast frame part 20 is separated upward from the fixing groove part 11 or selectively separated from the fixing groove part 11 in accordance with a direction in which the mast frame part 20 is rotated about the hinge axis 31 Can be inserted downward.

In detail, when the one end 21 of the mast frame part 20 is inserted into the fixing groove 11, the mast frame part 20 can be vertically and vertically aligned with the hull h, And can be used to connect the sails (s) to travel the ship. In contrast, when the one end portion 21 of the mast frame portion 20 is separated from the fixing groove portion 11, the mast frame portion 20 is positioned on the upper surface of the hull h about the hinge axis 31, As shown in FIG. As a result, the volume of the hull (h) occupied by the hull (h) becomes compact, so that it is easy to move to the land. As a result, it can be stably stored in a warehouse with a low ceiling, and it is also economical to prevent an excessive cost for storing and repairing because it prevents damage caused by the external environment.

It is preferable that the hinge shaft 31 is fastened through the hinge slot 22 and both ends of the hinge shaft 31 are fixed to the hinge rotation part 30. The hinge shaft 31 is fixed to the hinge rotation part 30. It is understood that the hinge shaft 31 is substantially limited to a hinge shaft that guides the hinge rotation of the mast frame part 20. [ desirable. It is preferable to understand that the position of the hinge slot hole 22 is changed corresponding to the direction in which the mast frame portion 20 is lifted or inserted into the fixing groove portion 11.

The mast frame part 20 is inserted into the fixing groove part 11 so that the mast frame part 20 is vertically erected with respect to the hull h. At this time, it is preferable that the fixing groove portion 11 is formed with a groove having a predetermined depth so that the mast frame portion 20 stably stands up.

Here, the depth of the fixing groove 11 may be set in a range of 8 to 15% of the entire length of the mast frame portion 20. [ When the depth of the fixing groove portion 11 is less than 8% of the entire length of the mast frame portion 20, the mast frame portion 20 is pressed against the fixing groove portion 11 by wind and external impact, So that it can be easily separated. Particularly, when the depth of the fixing groove portion 11 is smaller than the width of the mast frame portion 20, the mast frame portion 20 can be easily separated from the mast frame portion 20 during traveling.

On the other hand, when the depth of the fixing groove 11 is larger than 15% of the entire length of the mast frame 20, a stable fixing state can be maintained, but the mast base 11, on which the fixing groove 11 is formed, The volume of the portion 10 can be increased. As a result, the volume occupied by the mast base 10 in the hull becomes unnecessarily large, which may cause inconvenience that the efficiency of accommodating a person or an article in the ship 2 is lowered. Therefore, the depth of the fixing groove 11 is set in a range of 8 to 15% of the entire length of the mast frame portion 20, so that the mast frame portion 20 is stably fixed in a vertical state, The accommodation efficiency may be maintained.

A sliding groove portion 22c extending between the first end portion 22a and the second end portion 22b in correspondence to the distance L may be included.

When the mast frame part 20 is pushed into or lifted from the fixing groove 11, the position of the hinge shaft 31 is changed from the first end 22a to the second end 22b of the hinge slot 22, (22b). The position of the hinge shaft 31 may be changed substantially by changing the position of the one end 21 of the mast frame portion 20 so that the hinge shaft hole 31 corresponding to the hinge shaft 31 ) Is variable.

The first end portion 22a is formed at one end 21 of the mast frame portion 20 so that the first end portion 22a is hinged about the hinge shaft 31 and rotatably separated from the fixed- . That is, the distance w1 between the outer frame 21a of the one end 21 of the mast frame part 20 and the first end 22a is greater than the width w2 of the opening of the fixing groove 11 It is preferable that it is formed small. The one end 21 of the mast frame part 20 is rotated in the direction of the arrow A when the mast frame part 20 is hinged while the hinge axis 31 is constrained to the first end part 22a, Can be stably separated without being caught by the opening of the housing (11).

The hinge shaft 31 is constrained to the first end portion 22a so as to be guided along the turning radius of the hinge shaft 31 so as to guide the hinge rotation of the mast frame portion 20 more stably The rotation guide step 22d may be further formed. That is, the hinge shaft 31 can be held between the first end portion 22a and the rotation guide step 22d while the mast frame portion 20 is lifted.

The mast frame portion 20 in which the one end portion 21 is rotatably separated from the fixed groove portion 11 has a space area occupying the longitudinal side of the ship 2 as it is folded toward the upper surface side of the hull h It can be remarkably compact. Furthermore, since the mast frame portion 20 is folded at a multi-stage around the hinge folding portion 27, which will be described later, substantially only a space corresponding to the volume of the hull h itself can be secured even in a small space. Accordingly, the ship 2 can be stored on the land, which is economical compared to the conventional marine mooring and can be easily repaired and repaired, and can be prevented from being deformed or damaged by an external environment or impact. Therefore, economical efficiency and maintainability can be remarkably improved have.

The second end portion 22b is connected to the hinge shaft 31 fixed to the hinge rotation portion 30 in a state where the one end portion 21 of the mast frame portion 20 is inserted downward into the fixing groove portion 11 Is formed at a position where it can be received. Accordingly, even if the fixing groove 11 is formed to a depth sufficient to stably fix the one end 21 of the mast frame portion 20, The restriction of the one end 21 of the part 20 can be minimized.

That is, the hinge slot 22 is inserted into the fixing groove 11 at one end 21 of the mast frame 20 by the hinge shaft 31 fixed to the hinge rotation part 30 It can be opened long enough not to interfere. The one end 21 of the mast frame 20 is hinged around the hinge shaft 31 and is easily rotatably separated from the fixing groove 11. Thus, The usability of the display device 100 can be remarkably improved.

In detail, one end of the guide hinge part 133 may be hinged to the first hinge shaft 131 of the hinge rotation part 130. The other end of the guide hinge part 133 may be provided with a second hinge shaft 132 passing through the hinge slot hole 22.

That is, the mast frame unit 20 may be directly connected to the hinge shaft 31 (see FIG. 2) provided in the hinge rotation unit 30 (see FIG. 2) The guide hinge 131 may be further provided to guide the rotation between the rotation unit 130 and the mast frame 20.

The rotation center of the hinge rotation part 130 and the hinge slot groove 22 are formed in the same moving path as the rotation center of the hinge rotation part 130. Therefore, It is possible to easily fold and fold the spun yarn even if it is not positioned on the yarn. The rotation center of the hinge rotation unit 130 may be the center of the first hinge shaft 131.

Even if the distance between the end of the hinge slot 22 and the end of the mast frame 20 is slightly different from the width of the fixing groove 11, Since the angle of rotation and folding can be adjusted to easily insert and fix, the ease of use may be significantly improved.

Here, the hinge rotation unit 130 may be separately provided, and the base unit 130a may be fixedly coupled to the upper surface of the mast base unit 10, or may be integrally formed as in the above-described embodiment. Examples are within the scope of the present invention.

The foldable mast device 100 according to the present invention is characterized in that the folding mast device 100 includes a hinge slot 22 formed at one end 21 of the mast frame 20, And a hinge shaft (31) fixed to the rotary part (30). Accordingly, the volume of the ship can be reduced by the simple method in which the mast frame portion 20 rises and is folded and rotated around the hinge shaft 31, so that the storage property can be remarkably improved. In addition, since the mast frame part 20 is substantially connected to the hinge rotation part 30, it is possible to prevent the mast frame part 20 from being lost.

At this time, the mast frame part 20 is symmetrically disposed around the flat part 20b, and a pair of frame bars 20a having the depressions 20c and 20d formed on the flat part 20b are fastened to the fastening member 20f. &Lt; / RTI > In addition, since the ropes capable of operating the sails s and the sails s can be stored in the receiving grooves e1 and e2 formed from the depressions 20c and 20d, the storage property can be remarkably improved .

In addition, since the mast frame portion 20 is divided into the upper frame 24 and the lower frame 23, which are hingedly connected by the hinge folding portion 27, and folded in multiple stages, the ship 2 can be made more compact . At the same time, since the joint part 28 can vertically confine the upper frame 24 and the lower frame 23, which are divided when the mast frame part 20 is set up, is further provided, the usability can be further improved .

As described above, the present invention is not limited to the above-described embodiments, and variations and modifications may be made by those skilled in the art without departing from the scope of the present invention. And these modifications fall within the scope of the present invention.
