By forming an auxiliary fixing part consisting of a magic tape in which the numerical value is written in the vertical direction to wrap the upper and lower ends of the outer surface on one side of the left and right waist band of the configured waist protector, the user can conveniently and accurately While having an effect of attaching, by forming portions that are rubbed on the connection band, when the user secondly secures the waist guard, the user can tighten the waist guard more conveniently by preventing slippage of the connection band.

In addition, by configuring the waist support separately by using the magic tape to attach to the left and right waist band, it is easy to attach and detach the waist protector according to the user's convenience, and there is an advantage of convenient management such as changing the size of the waist protector. In addition, by forming a stopper to operate the pull string in one or two directions, there is an effect that the elderly or weak patients can easily tighten the waist guard secondary.

In general, the waist protector has a wide band-shaped both ends of the buckle or magic tape to be worn only on the waist to protect the waist, but the air circulation or tightening means uses only the first coupling means by the magic tape. By fixing in the user's belly, there is a problem that can not maintain the proper tightening degree because the difference in the degree of tightening the waist can not be properly supported.

In addition, to reinforce this, many designs have been devised to support the back and down supporters such as reinforcement cores or air tightening means to the inner side of the belt. Along with the problem, the technical configuration is complicated, and there is a problem that the manufacturing cost increases or the user cannot easily use it.

In particular, the waist protector that is fixed first using only the magic tape is tightened only from the front, so that the user may wear the waist protector properly because the user lacks the proper tightening force in the elderly or the patient with the waist disease. Not only was it difficult, there was a problem that can not be fixed to the spine, that is, the waist portion of the user.

The waist protector according to the present invention is formed between the left and right waistbands (1, 2) and the left and right waistbands (1, 2) that wrap the waist and fix each other by forming a magic tape on one side as described above. It consists of a connecting band (3) having a pull string (31) and a fastener (32) extending to one side to fasten the waist to the secondary tightening, while the left and right waist bands (1, 2) are connected to the band It consists of a fixing part (4) in the horizontal direction on the outer circumference of the waist bands (1, 2) so that the fixing device (32) of (3) is attached.

However, the waist protector according to the present invention, in particular, the above-mentioned conventional technique is generally do not know how much tightening of the user, especially in the case of the waist patient, even if the degree of uncomfortable to bear the degree of discomfort to the appropriate waist fixation force acts If you do not wear a waist protector can be reduced to the uncomfortable device that does not protect the back patient, it would be desirable to use the user to indicate the degree of adjustment to the waist dimension of the user.

Therefore, the present invention, the upper and lower ends of the outer surface to allow the user to attach the fastener 32 conveniently and accurately to any one side of the left and right waistband (1, 2) to indicate the degree of waist control according to the user It is to form an auxiliary fixing portion 41 made of a magic tape with a numerical value written in the vertical direction to surround the wealth.

In this case, the numerical values described in the auxiliary fixing part may be used by describing only the values using only the waist protector, but it may be preferable to use the same values used in conjunction with the waist restraint used together with the waist protector. 1 and FIG. 2)

And, the configuration of the connection band according to the present invention is a tightening plate 34 for supporting the pull string 31, the left and right cover 35 and the pull string 31 and the fasteners (31) surrounding the tightening plate 34 32), a pair of fastening plates 34 having an interlocking concave-convex shape having a plurality of tightening shafts 33 supporting the pulling string 31 are formed, and the fastening plate 34 is left. The left and right cover 35 is formed to be fixed to the right waist bands 1 and 2, and a pull string 31 connected to the tightening shaft 33 by zigzag to connect the pair of tightening plates 34 to each other. It is formed, and is fixed to the end of the pull string 31 is formed as a fastener 32 for fixing to any one of the left, right waistband.

At this time, the method of fixing the tightening plate 34 to the left and right cover 35 is generally preferable to sew because the left and right cover 35 is a woven material. (See FIGS. 3 and 4)

As such, the connection band and the pull string coupled thereto may be uncomfortable when the user is easily loosened or tightened. Therefore, the convex and convexities on the outer circumference of the tightening shaft 33 of the connection band 3 may increase the frictional force. The friction surface 331 or the shaft friction portion 332 coated with a silicon material is formed.

(Fig. 1 and Fig. 3)

In the case of using only a waist protector such as the present invention, the waist part must be completely fixed in the case of a patient injuring the waist, so that the left and right waist bands (1, 2) are separately connected to the connection band (3). As mentioned above, in the case of attaching to the fixed part, as described above, it solves problems such as the difficulty of uniform production and detachment of the waist protector and the waist rest which are caused by fixing the waist protector by using the projection and the groove or the ball. In order to make the waist half bed and the waist protector convenient by using a pedestal attachment portion 71 made of a magic tape to a portion where the waist rest 7 and the left and right waist bands 1 and 2 are fixed. Can easily remove the waistrest from the waistguard (see Figure 7).

The left and right waistbands 1 and 2 and the attachment and detachment means 6 of the connection band 3 are formed in a detachable part 611 made of a magic tape, and thus the left and right waist bands 1 and 2 are easily fixed as compared with the related art. In addition, the right waistband (1, 2) and the connection band (3) can be removed or stored, as well as the user's size will be more widely utilized, such detachable means (6) is the first connection band (3) After forming the connection piece 61 formed on the inner side of the left and right cover 34 of the left and right waistbands (1, 2) to form a detachable portion 611 corresponding to the one side end of the pair will be.

At this time, the width of the connecting piece 61 and the width of the detachable portion 611 may be the same or the width of the connecting piece is formed wider than the detachable portion may be configured to be able to adjust the size of the waist guard. )

In general, the left and right waist support (1,2) used in the waist protector is composed of a woven fabric of the double mesh formed so as not to take the user's sweat inside, the left and right waist support (1,2) is not folded Use a thick weave to have a slight elasticity, but when the left and right waist rests (1,2) are configured in this way, in the case of seasons such as summer or in the case of a lot of sweaty users, in case of sweat discomfort or in medical facilities When using the hygiene problems may occur, the left and right waist support (1,2) to form a circulation plate (8) formed with a plurality of through holes in the center inside, the circulation plate has an elastic force so that it is not easily folded In order to easily form a large number of through holes 81 for air circulation, it is desirable to use a thin plate body made of synthetic resin (see FIGS. 8 and 9).

This design makes it easier for the user to pull the connecting strap, which is the means of tightening the second waist guard, that is, the weaker users such as the elderly and the patient cannot pull the waist guard to the proper tightening position at one time so that one side or both sides can be divided and tightened to you. It constitutes a stopper (9) to operate the pull string 31 in the direction and is fixed to any one of the waist bands (1, 2) in the center of the pull string (31) of the connection band (3).

At this time, the configuration of the stopper (9), because the pull string 31 must be operated in one or both directions to use the one-way rotary port 92 and the sweet 94 using the pressure of the spring 93, Specifically, a pair of one-way rotary holes 92 are formed in the stopper 9 to correspond to the upper and lower sides, and the pair of one-way rotary holes 92 flow upward and downward so that the pair flows upward and downward. A long hole 911 is formed in the stopper body 91, and the spring 93 is installed to be fixed to the inner surface of the stopper body 91 so that the one-way rotary hole 92 is pressed to the corresponding surface, and the switch 94 is used. Then, the one-way rotary port 92 pressed by the corresponding surface is formed on one side of the stopper main body 91 so as to be released by the user.

At this time, the stopper (9) can be configured separately, but for convenience in use as a stopper fixing part (95) made of a magic tape on one side of the stopper body (91) to fix it to the fixing part (4) formed on the waistband. It can be attached and used in a position where the user can operate comfortably.

Looking at the configuration of the one-way rotary sphere (2) of the stopper (9), forming a "b" shaped rotary sphere main body 921, the inner circumference radially starting from the center of the axis on one side of the inside Accordingly, a plurality of fixing protrusions 922 are formed, and a cylindrical rotating body 925 having a fixing piece 923 having a locking protrusion 924 formed at an end thereof to rotate corresponding to the fixing protrusions 922 is formed. On the other hand, one side of the rotary sphere body 921 is mounted on the long hole 911 of the stopper body 91, while the switch 94 is installed to form an operating shaft 926 to extend to the outside of the stopper body 91 switch It is to be easily combined.

At this time, it is preferable that the number of the fixing pieces 923 on which the locking projections 924 are formed is one or more, but preferably two or more and less than four. (See FIGS. 10 to 12. )

In particular, in order to increase the fixing force of the pull string engaged between the corresponding rotator 925 of the one-way rotary port 92, the rotator 925 is made of a silicon material to increase the elasticity and friction along the outer circumference of the cylinder The rotating body friction surface of 927 is formed, and it is possible to increase the holding force of the stopper by extending the string friction portion of the pull string as described above (see FIG. 13).

Attachment means of the configuration of each of the above-mentioned magic tape may be adhesive or sewn, but it is preferable to sew for convenience of maintenance.

As described above, by forming an additional fixing part to the waist protector, the user can maximize the effect of the waist protector by accurately fixing the fixture in the proper position, by fixing the waist support and waist protector with magic tape, According to the convenience of the lumbar support can be easily used, and even if the lumbar support and waist protector are manufactured in separate sizes, with the universal effect that can be used together, the connection band for fixing the left and right bands forming the waist protector is also a magic tape. By fixing the left and right band by the connecting piece using the user, there is an effect that the user can easily separate and manage the left and right band and can be used for a long time without the risk of double damage.

In addition, by coating a part of the pull string fixed to the tightening shaft or the tightening shaft of the connecting band with silicon or forming an uneven surface on the tightening shaft, the pulling string is easily slipped on the tightening shaft when the user adjusts the gap of the connecting band by pulling the fastener. The elasticity of the waist protector is more easily tuned to the waistguard.

In addition, by forming a resilient circulation plate formed with a plurality of through holes inside the center of the left and right waistband, the user can eliminate the discomfort caused by the stuffiness or sweat when wearing the waistband, pulling the waistband By installing a stopper fixed to the waistband in the middle of the line, it prevents the loss of the lumbar fixation during sudden detachment of the fixture, and it is effective for the elderly or the patient to easily tighten the waist guard secondarily.
