Description

{A HOSE WINDING TOOL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose winding tool, and more particularly, to a hose winding tool for automatically or manually winding a hose.

Conventional hoses supplying various kinds of fluids or gases are used not only in various industrial fields but also in general households for various purposes. The conventional hose widely used in everyday life has a wide variety of hoses ranging from a short length of less than 1 m to a long length of more than 20 m depending on the environment and use.

Generally, hoses used in households are usually shorter than 1m, but long hoses of more than 20m are mainly used in various industrial fields such as agriculture and industry.

In particular, industrial hoses can be used in fire fighting and disaster prevention fields. Fire hoses, which are part of fire fighting facilities prepared for fire or safety accidents in factories in various fields that produce raw materials and processed products in various industries, It is.

These fire hoses vary from case to case, but most of them are very long, about 15m to 20m in length. This very long length of fire hose is very difficult to be wound due to its long length and weight.

In order to do this, the winding operation of the fire hose must be carried out precisely and correctly in the first place, and must be kept in that state after such winding operation. This allows the fire hose to be deployed quickly in emergency situations without kinks.

As described above, the winding work of the fire hose is very important for safety reasons. The fire hose is not only heavy in itself but also is not easy to take up and pull out due to its long length.

Therefore, in the winding operation of the fire hose, the amount of the hose to be wound is large and the weight of the hose itself is heavy, so that one worker can not afford to handle it alone, and usually two workers are put in.

At this time, there is no equipment for winding the hose. As shown in Fig. 1, in the state in which the hose 1 is spread on the floor, the operator bent the waist and manually winds the hose.

Such manual winding work takes a lot of time and slows the work progress, which hinders quick work activities in case of an emergency. In addition, if the fire hose is not wound properly and tangle or twist occurs, there is a possibility that the safety hose can not be used in a timely manner in an emergency and may lead to a larger safety accident.

In addition, workers who lean back for a long period of time can be overwhelmed by the body of the worker who takes up the hose.

Therefore, a fire hose, which should be used for the safety of work sites and workers as a part of fire fighting facilities, may face a situation where the safety of work sites and workers is threatened.

In order to facilitate an understanding of the description of the embodiments of the present invention, elements denoted by the same reference numerals in the accompanying drawings are the same element, and among the constituent elements that perform the same function in each embodiment, Respectively.

Further, in order to clarify the gist of the present invention, a description of elements and techniques well known in the prior art will be omitted, and a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

However, the technical features of the present invention are not limited by the embodiments to which the present invention is applied or explained in the following embodiments, and various modifications are possible within the technical scope of the present invention.

Hereinafter, with reference to FIGS. 1 to 7 attached hereto, the detailed configuration of the hose winding tool according to the present invention will be described.

The hose winding tool according to the present invention may be configured to include a main shaft 10, an auxiliary shaft 16, and a lower pedestal 20. However, according to each embodiment, the components may be partially used or modified.

2A shows an embodiment of the present invention in which the main shaft 10 is used alone. The main shaft 10 is made up of a lower portion 11, an extension portion and an upper portion 12, and is made of a material having appropriate strength enough to repeatedly wind a hose having a long length But it is not limited by the present invention.

The lower portion of the main shaft 10 is bent and extended so as to form a hollow portion with one side opened toward the bottom surface. In one embodiment of the present invention, the lower portion extends downward from an upper portion bent to form a handle, and the lower portion is provided to wind the hose by rotating in contact with the hose.

At this time, an auxiliary shaft, which is fixed to one side of the main shaft, is bent and extended downward so as to be spaced apart from the main shaft by a predetermined distance, and an auxiliary shaft into which a hose is inserted, may be connected to the inside.

The main shaft 10 and the auxiliary shaft 16 are connected to each other so that the lower portion of the main shaft can form an 'n' shape. One end of the hose 1 may be inserted between the main shaft and the auxiliary shaft.

The hose insertion space in which the main shaft and the auxiliary shaft are mutually formed can be changed by adjusting a separation distance between the main shaft 10 and the auxiliary shaft 16. In consideration of the thickness of the hose, Can be applied.

However, it may be desirable to provide the hose with a slightly larger thickness than the hose used to effectively secure one end of the hose.

Here, even if the hose insertion space is provided slightly larger than the thickness of the hose 1, the one end of the hose can be efficiently fixed by the fixed unit 31 installed on the auxiliary shaft and disposed in the hose insertion space have.

The fixed unit 31 is provided inside the auxiliary shaft 16 and is provided to extend or contract within the hose insertion space so that it can be brought into close contact with the hose at the time of hose insertion.

That is, it may be provided as an elastic member 31a that is fixed to the auxiliary shaft, is disposed to face the main shaft, and extends or contracts to be in close contact with the inserted hose.

Thus, when the thickness of the hose 1 is considerably thinner than the hose inserting space so that it is difficult to fix in the hose insertion space, the hose 1 can be brought into close contact with the hose to push the hose toward the main shaft.

The elastic member 31a can be stretched or contracted by elasticity, which can compensate for the difference in hose insertion space and hose thickness. Therefore, it is preferable that the elastic member 31a is normally provided so as to fill the area of the hose insertion space.

When the hose is inserted between the elastic member and the main shaft, the elastic member 31a is contracted by an amount of elasticity of the hose, As shown in Fig.

Thereafter, when the hose is removed from the hose insertion space, the elastic member 31a is stretched again by its original elasticity to fill the region of the hose insertion space.

However, in the embodiment in which the main shaft 10 is used alone as described above, the drawing unit 32 provided on the lower receiving plate 20 is not used.

Next, the upper portion 12 extending upward from the lower portion 11 of the main shaft 10 and provided to be bent in a predetermined section to form a handle will be described.

Since the upper portion 12 forms a handle, it is preferable that the upper portion 12 is formed at a height enough for the user to hold the user's waist without taking his / her back in consideration of the average height of the user. As shown in FIG.

As shown in FIG. 2A, the upper portion 12 may be bent once from the end portion of the extended portion, and then bent upward again to form the handle. However, the handle is for the user's convenience, And can be appropriately changed by the convenience of the user.

The main shaft 10 configured as described above can be rotated by a user to wind the hose. That is, both ends of the lower portion 11 of the main shaft are extended to be in contact with any one of the bottom surfaces, thereby forming the rotation axis of the main shaft.

One hand of the user holds the extended portion of the main shaft 10 and the other hand grasps the handle formed on the upper portion 12 of the main shaft 10 and then moves the hand holding the handle to move the main shaft 10, The hose 1 fixed to the lower portion 11 of the main shaft 10 can be wound by rotating the hose 1 in a predetermined direction.

Here, in the present invention, a bottom plate, which will be described later, is provided instead of a bottom surface. When the main shaft 10 is used alone, the bottom plate replaces the bottom plate.

At this time, the friction-preventing member 13 may be installed in the lower part of the auxiliary shaft 16 so as to reduce the friction upon rotation, regardless of whether the main shaft is used on the floor surface or on the lower pedestal.

One side of the friction-preventing member 13 is fixed to the lower end of the auxiliary shaft 16, and the other side is provided to be in contact with the floor surface or a below-mentioned lower pedestal plate. In the present invention, a circular wheel member is used as an example of the friction preventing member 13, but the present invention is not limited thereto.

2b, the lower support plate 20 described above is introduced, and the main shaft 10 and the auxiliary shaft 16 are formed in the same manner as described above, In addition to the unit 31, the drawing unit 32 is further included.

The lower support plate 20 is a component that replaces the bottom surface of the main shaft in the embodiment. One surface of the lower support plate 20 is in contact with the bottom surface, and the other surface is in contact with the main shaft 10 , And is provided to support the hose to which the main shaft is wound.

That is, the user can make contact with the lower portion 11 of the main shaft at one point on the other side of the lower foot plate 20 and insert one end portion of the hose 1 into the hose insertion space where the elastic member 31a is installed The rotation shaft of the main shaft 10 can be formed as described above.

When the main shaft 10 is rotated in a predetermined direction in the same manner as described above, the hose 1 can be wound on the lower support plate 20 and the wound hose 1 can be wound on the lower support plate 20 It remains.

At this time, an inlet unit 32 for guiding the insertion of the hose 1 into the hollow portion is provided on the other surface of the lower support plate 20. [ The drawer unit 32 may be a plurality of protrusions 32a and 32b protruding at a predetermined height from the other edge of the lower plate 20 as shown in FIG. The protrusions are spaced apart from each other by a predetermined distance so that a space through which the hose 1 passes is formed between the protrusions 32a and 32b.

In this case, the spacing distance and the protrusion height are determined in consideration of the size of the wound hose 1, the spacing distance is set to be slightly larger than the thickness of the hose, and the protrusion height is set to be slightly higher than the width of the hose, .

The hose 1 having one end fixed to the hose inserting space of the main shaft 10 is drawn into the lower leg plate 20 without being tangled or twisted, And can be wound up successively by the shaft (10).

6 and 7, when the hose 1 is completely wound on the lower support plate 20 as described above, the lower support plate 20 can be easily moved to the storage place, A plurality of moving wheels 21 as shown can be installed.

At this time, if the mobile wheel 21 is foldably installed, it can be more effective. That is, when the hose is wound by coupling the main shaft 10, since the lower support plate 20 does not move on the bottom surface when the moving wheels are folded, it will be easy for the winding work. The lower support plate 20 can be moved with less force on the floor surface, so that the user can easily carry the heavy hose 1 without applying a large force.

For this, if the groove for receiving the moving wheel is formed in the lower part of the lower support plate 20 when the moving wheel is folded, the lower part of the lower support plate 20 is brought into contact with the bottom surface, So that the winding operation can be stably performed.

The main shaft 10 is a member that directly contacts the user's hand regardless of whether the lower support plate 20 is used or not. The user who winds up the hose is allowed to hold the handle 10 of the main shaft 10 for a long time or repeatedly, And is rotated.

In this case, the user's hand may feel fatigue easily. The main shaft 10 may have a predetermined protective member to relieve fatigue of the user's hand.

6, the main shaft 10 is provided to surround one side of an extension extending from the lower portion 11 to the upper portion 12, the inner surface of which is connected to the bearing B, The outer surface may further include a first protection member 14 provided as a friction preventing member and a second protection member 15 provided to surround the handle formed at the bent upper end and provided on the outer surface as a friction preventing member .

Since the friction preventing member prevents the user from missing the main shaft 10 due to sweat on the user's hand or other lubricant that can be adhered at the work site, You do not have to hold on to force. Especially, if it is made of a soft material such as rubber, it will be enough to relieve fatigue of the user's hand.

The reason why the inner surface of the first protection member 14 is connected to the main shaft 10 by the bearing B is that unlike a hand holding the second protection member 15 provided on the handle, It is preferable that the first protection member 14 does not rotate because the rotation shaft of the main shaft 10 is formed by the other hand holding the first protection member 14. [

Therefore, the bearing B provided on the inner surface of the first protection member 14 serves to realize the rotation of the main shaft 10, but to prevent the rotation of the first protection member 14. [

Meanwhile, in another embodiment of the present invention, as shown in FIG. 3, a main shaft mounted with a drive motor 2 connected to a control unit C is provided. This is to reduce the inconvenience that the user has to manually rotate the main shaft, and the drive motor 2 can be controlled by the control unit C to rotate and rotate.

That is, the rotation shaft of the drive motor 2 is connected to the upper portion 12 of the main shaft so that the main shaft is rotated by the rotation of the drive motor. However, in the present invention, the installation position of the driving motor 2 is the upper portion of the main shaft 10, but this is also a matter that can be appropriately changed depending on the use environment.

In addition, by connecting the drive motor 2 to the control unit C, the user can start or stop the rotation of the drive motor 2 only by a simple operation of the control unit C, Can also be adjusted.

It is obvious to a person skilled in the art that the winding speed of the hose 1 is increased when the rotational speed of the drive motor 2 is rapidly operated and the winding speed of the hose is slowed when the rotational speed of the drive motor is operated slowly .

In addition, the control unit C may be connected not only to the drive motor 2 but also to the lead-in unit 32, as shown in Fig. 5A.

5B, the inlet unit 32 provided with the plurality of projections 32a and 32b may be provided with a light emitter I and a light receiver L, respectively.

A light emitting body is provided on the inner surface of one of the projections and a light receiving body for detecting light from the light emitting body is provided on the inner surface of the other projecting portion. And the light emitter are connected to the control unit C, respectively. The controller may be configured to sense a hose inflow state according to a value output from the light receiver and output a predetermined signal.

Then, the hose (1) passing between the plurality of projections will block the light detected by the light emitting body from the light emitting body, and will not output any value during the drawing of the hose at the light receiving body. 5B, the control unit C senses such a state, and the hose 1 may be provided with a signal indicating that the hose 1 is being drawn through a predetermined display means.

On the contrary, it is obvious that the hose 1 does not pass between the plurality of protrusions while the value detected from the light emitting body is outputted from the light receiver, and the control unit C, which senses this state, And outputting a signal indicating that the signal is not input through a predetermined display means. However, in this case, the hose may not be brought in due to a series of problems, or the hose may be in a completed state.

As described above, the components of the hose winding tool 100 according to the present invention described above can be used either as a single component or as a part of components, It should be noted that it can be appropriately determined by the work environment and the user.
