The present invention relates to a boat equipped with a furnace capable of preventing the above-mentioned problems.

In addition to motor boats, boats are used extensively in racing, as well as in various leisure activities, such as boats for obtaining thrust using a furnace.

Conventionally, there have been attempts to improve a rowing boat in various ways.

For example, there is a utility model registration No. 20-0325235 (registered date August 22, 2003) [structure of a furnace for a leisure boat]

This registration design combines a half-split braid at the outer end of the furnace to provide a strong propulsion force when widened forward and folded at backward to avoid the resistance of water, thereby obtaining the maximum propulsion force with minimum force. As regards the structure,

A rod-shaped support bar formed at both ends thereof with a handle and a fastening piece integrally formed; A hinge coupled to the fastening piece on the inner side and two braids coupled to the plate material on the outer side; A fixing band having both ends fixed to an inner surface of the braid to adjust a momentum of the braid; And a cap nut screwed to an end of the fastening piece to support the braid so as not to be detached.

As described above, the above-mentioned registration design is concerned with the improvement of the furnace for a play boat in which an inexperienced person or a beginner mainly takes a ride. However, like the conventional rowing boat, It is a boat that applies the advantage of getting thrust,

This is a typical rowboat-optimized boat optimized for human musculoskeletal characteristics.

As an attempt to modify such a conventional rowing method, there is a utility model publication No. 20-1990-0003819 (published on May 01, 1990) [boat type furnace].

This announcement was designed to make the bottom plate attached to the tip of the operation be able to flow at an angle of 90 °,

Conventional boats have been constructed by fixing or fixing the boiler plate in the furnace in one piece, and when the water is scratched, there is no defect, but when the boat is rotated, it is subjected to air resistance and water resistance. And a stopper protruding from the tip of the operation stopper is formed in the furnace composed of the knobs so that the stopper plate is rotatably installed.

In addition, there is a utility model registration No. 20-0143679 (registration date January 27, 1999) [a tube boat for rowing in front] with the above-mentioned Utility Model Bulletin 20-1990-0003819,

This registration design also provides a boats that can be safely laid forward by installing a well-known furnace on the flange of a boat, which can easily be assembled into three-dimensional boats,

However, in the Utility Model No. 20-1990-0003819 and Utility Model Registration No. 20-0143679, all of the gears are formed by gears interposed in the middle of the row gears, and there is no problem in pushing the water, This is a technology that is inadequate for both racing use and playful use because it is a complicated constitution related to the operation of moving the worker in order to push out the worker and this acts as a price rising factor, a residual height and a noise source.

In addition, the above conventional techniques have a complicated structure for reducing the power consumed in rowing, and in particular, considering the fact that the boat is exposed to moisture for a long time due to the characteristics of the boat, .

Further, in order to prevent direct contact of the boats with the boats when the boat travels, a rigger must be provided in the lateral direction of the boats, so that the operation structure of the boats is more complicated.

Accordingly, the present invention has been made to solve the above-mentioned problems,

A middle portion of a rod (that is, a rope) of a furnace is coupled to an operation shaft (a reeder) provided in a conventional boat, and the rope is unloaded from the furnace, The conventional row boat, which is provided with thrust by plowing the paddle in the conventional reverse form, is constructed to stir the paddle while looking at the front. In addition, the paddle is adjusted in accordance with the characteristics of human musculoskeletal, And the same thrust can be obtained,

Further, the blade provided at the end of the row canal is immersed in water to pull the water to push the water to obtain the thrust. Then, the blade is lifted out of the water and then the paddle is pushed again to reduce the force required to return to the original position And a rowing unit for providing an elastic force required for upward pivoting operation of the furnace,

Hereinafter, the present invention will be described with reference to the accompanying drawings.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a boat having a furnace in which a passenger can obtain a thrust necessary for traveling while looking ahead,

As shown in FIGS. 1 to 5, a ship main body 10 on which a user is largely loaded is provided with a column 20 and a mount (not shown) for facilitating the return operation of the furnace 50, A roving unit R having a rod 30 and a furnace return means 40, a furnace 50 used to obtain a thrust by being fitted to the mounting rod 30, (60) for preventing breakage of the movable member (10).

The boat main body 10 is a known type in which one or more passengers are allowed to ride on the seat so as to pivot the furnace 50. The boat main body 10 has a furnace mounting portion 11 at the bottom portion, And a sidewall 12 connected to the upper end of the main body 10. The main body 10 may have a variety of materials, sizes, and shapes.

The rowing unit R includes a column 20 installed at the furnace mounting portion 11 and an inner end connected to the column 20 and a mounting hole 31 at an outer end, A mounting rod 30 having a hinge portion 32 which is rotatably coupled to the front and rear of the hinge portion 32 so as to be rotatable about an axis of the hinge portion 32, Means 40 is provided to allow the furnace 50 to obtain the thrust necessary for traveling the paddle boats in a state in which the user is present on the rear side of the furnace mounting portion 11 while facing the front.

The pillar 20 is installed on the upper surface of the furnace mounting portion 11 so that the mounting rods 30 are provided on both sides of the pearl body 10 in each pillar 20 so that the two pans 20 can be stacked Let's do it.

The mounting rod 30 can be detached and attached to the furnace 50 while being interlocked with the furnace return means 40 to be described later so that rowing, (Hereinafter referred to as the upward return operation of the furnace 50) when the furnace 50 is again pushed while the blade is lifted from the water after the thrust is obtained by pulling the blade 50 By reducing consumption, both boys and girls can easily ride and enjoy the boat.

Specifically, the mounting rod 30 is formed in a pipe shape so as to penetrate the furnace mounting hole 31 along the longitudinal direction, and has a hinge portion 32 that is fitted to the outside of the column 20 in the form of a grip on the inner end thereof do.

The hinge axis of the hinge portion 32 is coupled to the column 20 so that the column 20 itself is rotatably coupled to the furnace mounting portion 11 in the horizontal direction as shown in FIGS. 1, 3 and 4,

An extracorporeal tube 35 extrapolated to the column 20 inside the hinge portion 32 is separately coupled to the inside of the hinge portion 32 as shown in Figs. 2 and 5,

The mounting rod 30 can freely rotate back and forth and up and down about the connecting portion of the column 20,

At this time, the presence or absence of the extracorporeal tube 35 only differs depending on whether the height of the hinge portion 32 is adjustable in the longitudinal direction of the column 20 or not.

The mounting rod 30 further includes a supporting portion 34 projecting laterally from the outer end of the mounting rod 30. The supporting portion 34 is provided with a fitting hole (not shown) formed in the longitudinal direction of the mounting rod 30 .

At this time, the present invention can be divided into the first embodiment and the second embodiment according to the concrete configuration of the furnace returning means 40. [

First, as a first embodiment shown in Figs. 1, 3 and 4, the furnace returning means 40,

And a tension spring 41 having an inner end connected to the column 20 and an outer end connected to an outer end of the mounting rod 30 and exerting an elastic force in a compression direction.

The elastic force of the tension spring 41 acts upon the upward movement of the furnace 50 so that the paddling can be performed with a small force do.

Specifically, when the furnace 50 is mounted on the mounting rod 30 and the force is not applied, the mounting rod 30, that is, the furnace 50 is turned upward by the elastic force of the tension spring 41, It sounds.

When the furnace 50 is pivoted downward and then pulled down so that the blade is immersed in water with the furnace 50 being pushed forward, the furnace 50 swings backward with the pillar 20 as an axis, A thrust for advancing the main body 10 is generated.

At this time, when the mounting rod 30 is rotated downward, the tensile spring 41 is expanded in the longitudinal direction to generate an elastic force.

Since the elastic force of the tension spring 41 acts when lifting the furnace 50 to lift the blade out of the water, the user can forcibly remove the furnace 50 from the water and force the force applied to the furnace 50 The furnace 50 is automatically rotated upward to easily return the furnace 50 upward.

Further, in the state in which the furnace 50 is turned upward by the tension spring 41 and returned, the consumption of the force for maintaining the rise of the furnace 50 when the furnace 50 is pushed forward is unnecessary,

As a result, when the above-described series of operations is repeated, that is, in the rowing operation for obtaining the thrust, the consumed force is reduced as compared with the conventional rowing method, so that the boat body 10 can be driven more easily.

Meanwhile, the elastic force required from the tension spring 41 may vary depending on the user's age, body size, sex, and the like.

In order to adjust the elastic force of the tension spring 41,

The mounting rod (30) further includes a support portion (34) protruding from an outer end thereof and having an insertion hole formed in the longitudinal direction of the mounting rod,

The tension spring 41 includes an engaging nut 42 fixed to an outer end of the tension spring 41 and an elastic force adjusting bolt 43 inserted in the fitting hole and screwed into the engaging nut 42 so as to be adjustable in length.

The adjusting bolt 43 is a conventional bolt having a threaded portion of a predetermined length and is fixed to the outer end of the tension spring 41 by a fixing bolt 43 Can be screwed to the coupling nut (42).

Therefore, when the adjusting bolt 43 is inserted into the fitting hole and the threaded portion is screwed to the coupling nut 42, the connection of the column 20, the tension spring 41 and the mounting rod 30 is completed,

At this time, depending on the extent to which the adjusting bolt 43 is screwed to the engaging nut 42, the length of the threaded portion is changed and the degree of expansion of the tension spring 41, that is, the length of the tension spring 41, ) Can be adjusted by adjusting the elastic force of the elastic member.

Next, as a second embodiment shown in Figs. 2 and 5,

The mounting rod 30 includes an extracorporeal tube 35 extruded into the column 20 so as to be able to move up and down along the column 20 and connected to the hinge part 32,

The furnace returning means 40 includes a compression spring 44 whose upper end is supported by the column 20 and whose lower end is supported by the outer introducing tube 35 and which exerts an elastic force in a direction opposite to the compression.

As described above, the extracorporeal tube 35 ensures the forward and backward rotation of the mounting rod 30 and allows the mounting rod 30 to move up and down in the longitudinal direction of the column 20. [

When the compression spring 44 is compressed in the upward return operation of the furnace 50 as in the case of the tension spring 41, The elastic force of the spring 44 acts to enable the paddling with a small force.

The compression spring 44 is fixed to the column 20 by the upper support plate 45 fixed to the column 20 by supporting the upper and lower ends of the compression spring 44 on the support plates 45 and 46, So that the hinge portion 32 of the mounting rod 30 and the extracorporeal tube 35 are subjected to the downward pressure by an elastic force acting to push the lower support plate 46 downward.

At this time, in the second embodiment, the mounting rod 30 is configured such that the hinge portion 32 and the external introducing tube 35 are disposed at the upper end of the side wall portion 12 of the ship body 10, more strictly, ) Of the lower surface of the substrate.

Therefore, when the furnace 50 is rotated downward to obtain the thrust in the series of rowing operations described above, the mounting rod 30 is pressed against the side wall portion 12 (more strictly, the friction reducing plate 61) The mounting rod 30 is pivoted downward and the reaction of the mounting rod 30 causes the hinge portion 32 and the external intubation tube 35 to rise to the upper side of the column 20 The compression spring 44 is compressed and elastic force is accumulated.

The lower support plate 46 is pushed downwardly by the elastic force of the compression spring 44 and the hinge part 32 and the outer support part 44 are pushed downward by the elastic force of the compression spring 44 when the furnace 50 is returned upwardly after the thruster is generated. The user can move the insertion rod 30 by the seesaw motion of the loading rod 30 by the compression spring 44 even if the user does not give the extra force to lift the loading rod 30, The upward turning return and the forward return operation can be performed with a small force, and the rowing operation of the furnace 50 can be performed more easily as in the first embodiment.

In addition, in the second embodiment, in order to adjust the elastic force of the compression spring 44,

The column 20 includes threads on an outer circumferential surface thereof and a fixing nut 21 screwed on the column 20 at an upper portion of the upper support plate 45 to limit the height of the upper support plate 45.

The fixing nut 21 is a general hexagon nut and its height fixed by being screwed to the column 20 is changed so that the height of the upper supporting plate 45 supported by the fixing nut 21 can be changed.

Therefore, when the height of the fixing nut 21 is lowered, the compression spring 44 is compressed as the upper support plate 45 is lowered. On the contrary, when the height of the fixing nut 21 is increased, The compression spring 44 is inflated and the compression degree of the compression spring 44, that is, the length of the compression spring 44, is changed, so that the elastic force of the compression spring 44 can be adjusted and adjusted.

In addition, the first embodiment using the tension spring 41 and the second embodiment using the compression spring 44 can be applied not only to the first embodiment but also to the second embodiment simultaneously. 5 that the tension spring 41 and the support portion 34 of the first embodiment are provided together.

Next, the furnace 50 is known for obtaining a thrust, and a blade (not shown) is provided at the outer end of the pipe-shaped rod, You can have an appearance.

However, the furnace 50 of the present invention is different from a conventional furnace in that the furnace has a structure in which the mounting state can be stably maintained while allowing the mounting rod 30 to be detached and attached easily.

Specifically, the furnace 50 is provided with a fitting groove 51 on the outer peripheral surface of the (inner) end of the rod,

The mounting rod 30 is inserted into the slit 30a while being inserted into the slit 30a and the mounting rod 30 communicating with both sides of the furnace mounting hole 31 corresponding to the fitting groove 51, And a mounting ring (36) having an engaging portion (36a) engaged with the fitting groove (51).

The slit 30a has a predetermined length in the circumferential direction of the mounting rod 30 so as to communicate with the furnace mounting hole 31. The fitting groove 51 has a width corresponding to the slit 30a The outer circumferential surfaces on both sides of the furnace 40 are concave.

The mounting ring 36 has a locking portion 36a protruding inward at both ends, and an elastic force is exerted in a direction in which the both side locking portions 36a are engaged with each other.

Therefore, after the furnace 50 is inserted into the mounting hole 31 of the mounting rod 30, the fitting portion 36a of the mounting ring 36 is forcedly fitted to the mounting rod 30 in alignment with the slit 30a When the direction of the furnace 50 is aligned, the both side engaging portions 36a are inserted into the fitting grooves 51 through the slits 30a to be engaged with each other, thereby completing the mounting of the furnace 50,

When the furnace 50 is dismounted, when the holding ring 36a of the mounting ring 36 is pulled out, the mounting ring 36 is opened and the engaging portion 36a is released from the fitting groove 51, So that the furnace 50 can be separated.

The present invention facilitates the attachment and detachment of the furnace 50 by using the mounting ring 36 in a one-touch manner, and facilitates detachment, storage, transportation, and the like of the boat body 10 and the furnace 50.

The present invention is not limited to the configuration in which the furnace 50 is pivotally supported on a separate operating shaft (re- liger) as described above, so that the mounting rod 30 is positioned on the outer surface of the side wall portion 12 of the ship body 10 So that friction is generated.

Therefore, when the loin is repeated for a long period of time, scratches or the like may be generated on the outer surface of the side wall portion 12 of the ship body 10, and abrasion may be caused by repetitive friction, and the ship body 10 may be damaged.

A friction reducing plate 61 hinged to the upper end of the side wall 12 of the ship body 10 so as to be vertically rotatable and hinged to the mounting rod 30 when the loading rod 30 is lowered, (Not shown) for providing an elastic force so as to rotate the upper and lower plates in the upward direction.

The frictional reducing plate 61 is a plate having an area corresponding to the forward and backward rotation range of the mounting rod 30 and is hinged to the upper end of the side wall portion 12 of the ship body 10 at both upper ends thereof with a rotary shaft, do.

The friction reducing plate 61 has a sliding pad 61a attached to its outer surface (upper surface in the drawing) to reduce frictional force with the mounting rod 30.

The slide pad 61a is a kind of film bearing made of a material having a low friction coefficient.

The elastic body elastically supports the friction reducing plate 61 upward to have the same inclination as that of the mounting rod 30 in a state where no external force is applied to the friction reducing plate 61, .

When the furnace 50 is rotated downward to obtain the thrust, the mounting rod 30 is first brought into contact with the frictional reducing plate 61 and rotated downward together with the frictional reducing plate 61, The shock to the rod 30 is relieved,

The frictional abatement plate 61 prevents the mounting rod 30 from directly contacting and rubbing against the upper end of the side wall portion 12 when the water pushing operation is performed by pulling the furnace 50, Protect.

The frictional reducing plate 61 is replaceable with respect to the main body 10 so that when the sliding pad 61a or the frictional reducing plate 61 is worn out, only the frictional reducing plate 61 is replaced and used Thereby reducing the maintenance cost of the boat.

Particularly, as described above, the present invention is not limited to the conventional rowing method in which the user advances while looking backward, but the operating axis (ligature) for changing the direction of the furnace 50 is unnecessary A direct friction between the mounting rod 30 and the side wall portion 12 of the ship body 10 can not be prevented and therefore it is possible to prevent damage to the ship body 10 through the friction reducing means 60 have.

(Not shown) formed at the upper end of the side wall part 12 so as to be recessed downward to receive the friction reducing plate 61. The rotation shaft of the friction reducing plate 61 is fixed to both sides And is hinged to the inner side surface.
