Description

  The present invention relates to a duvet fixing tool mainly for preventing a slippage and a blanket from slipping out or sliding down.

  When you wake up and notice while sleeping, the futons and blankets are often dislodged, and there are often troublesome things such as falling down and rearranging, so small children who can not fix themselves and those with physical disabilities should sleep well It will catch a cold. The current situation is that parents and nurses will re-cover the futon.

  In order to solve such a problem, an invention has been proposed in which a futon and a blanket are fixed by using a receptor having a locking means and an opening / closing mechanism.

Further, an invention in which a small clip with an opening / closing mechanism is attached to a string or the like has been proposed as a means for preventing the comforter from falling off.

  However, although this patent document 1 has a certain fixing force and is excellent, the structure is complicated and expensive, and there is a possibility that a sense of incongruity in use such as size and weight may occur.

  In addition, although Patent Document 2 is excellent in terms of being small and light, it tends to fix only the hem and cover of the futon due to the structure and size of the pinch, and it is detached when used for a long time or when the sleep is intense. There is a possibility that.

  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a low-cost futon fixing tool that can firmly fix a futon and a blanket for a long time without a sense of discomfort.

  In order to achieve the above object, the present invention is characterized in that the futon and the blanket are fixed so as not to be sandwiched and displaced by a shape configuration that exhibits the elasticity of the sandwiching body gradually narrowing from the insertion gap and the friction characteristics with the futon. To do.

  This is because it will be weakly disengaged only by holding by the elastic force of the material, so it will be firmly fixed without shifting for a long time by adding a shape configuration that fully utilizes the friction characteristics of the futon and the wire rod etc. . The shape configuration includes means such as increasing the friction and strengthening the fixing force by, for example, the horizontal arrangement or the curved arrangement of the holding body.

  According to a second aspect of the present invention, a wide gap is provided at the leading end of the holding body so as to allow one end of a pull handle, a futon or the like to be held and hidden.

  The futon was thick and it was difficult to put it in a holding body without an opening / closing mechanism even if it was pushed or pulled. However, in these inventions, one end of a futon or the like can be inserted from a wide gap, and the handle can be pulled between the supports.

  According to a third aspect of the present invention, a finger clearance gap is provided from the center of the holding body to the rear part so that the finger does not collide when pulling the futon.

  This prevents finger injury and makes it easy to pull the futon firmly into the back.

  Since this futon fixing tool does not have a complicated structure such as an opening / closing mechanism, the futon fixing tool can be provided thinly, lightly and inexpensively. In addition, the duvet cotton is relatively crushed, and the duvet cotton is widely wrapped and firmly held, and can be fixed for dozens of days even in a sleeping phase that turns over many times. In addition, it is a safe and simple way to sandwich.

  Unlike papers, futons are thick, have inclusions, and are flexible. Such a futon has a unique characteristic in how to bite and how to generate friction depending on the arrangement relationship with the wire and the shape configuration. In the present invention, the elastic force of the material is fixed by utilizing the frictional characteristics of the futon and the wire. However, since the explanation of the operation must be described with reference to the drawings, serial numbers 0028 to 0036 are detailed. I will explain.

  Next, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the futon fixing tool 1 of the present invention is provided with two elastic holding bodies including an outer holding body 2 and an inner holding body 3 on the left and right sides, and is not linearly parallel. It is configured to be curved inward and face each other in an arc shape. This is because, as will be described in detail later, in the configuration in which the sandwiching portions are curved and face each other rather than being linearly parallel, the fixing force increases due to the frictional characteristics with the futon.

  The pull handle 4 is formed by connecting the tips of the outer holding bodies 2 in an arc shape, and has a handle for pulling the futon fixing tool 1 in the opposite direction when pulling the futon to be held. Yes. Also, it is better to have an arc shape so that the end of each holding body protrudes and does not injure such as piercing eyes, which also serves as safety.

  The inner sandwiching body distal end portion 5 is formed by connecting the distal ends of the left and right inner sandwiching bodies 3 to form an arc-shaped branch, and has a role of smoothly guiding futons to be sandwiched between the left and right sandwiching bodies.

  The futon insertion gap 6 is formed with a large gap between the pull handle 4 and the inner holding body 5, and the reason why the gap is wide is as follows. This is so that 10 and the blanket 11 can be picked together. In addition, as shown in FIG. 7, even when a mid-futon is inserted, the finger can be inserted deeply so that it can be gripped firmly as a handle.

  With these configurations, a large insertion port is always secured while being planar, and it is safe.

  The end portion 7 is formed in an arc shape by connecting the ends of the outer holding body 2 and the inner holding body 3, and is provided symmetrically.

  The finger punching gap 8 is a space penetrating between the end portion 7 from the vicinity of the center. As shown in FIG. 7 to FIG. 8, when grasping one end of the comforter 10 and the blanket 11 with a finger and pulling it to the back, It is to prevent it from occurring.

  Originally, futons could not be pushed in easily because there was no waist, and thick futons could not be put in easily if there was nothing to support them. However, if the pull handle 4 and the finger removal gap 8 and the like are effectively used in such a configuration, the comforter 10 and the blanket 11 can be easily drawn to the end portion 7 and held therebetween.

  The material of the futon fixture 1 may be an elastic material such as plastic or glass fiber as long as it is an elastic material, but a metal having elasticity is desirable from the viewpoint of durability.

  FIGS. 3 to 5 are reference diagrams showing side surfaces and the like, and when formed of plastic or the like, thickness, thickness, reinforcing shape, and the like are added to ensure strength, and are not necessarily limited thereto. .

  In addition, when it joins with metal etc. and joins with either, since there is a risk of injury to the hand when it breaks, joining at the inner holding body tip 5 such as welding It is desirable to do.

  Regarding the principle of fixing the futon fixing tool 1 described above, the elastic force of the material is necessary, but it is not fixed only by the elastic force.

  From this point of view, a shape configuration capable of exhibiting friction characteristics with the futon will be described.

  As shown in FIG. 9, the outer sandwiching body 2 and the outer sandwiching body 3 are provided horizontally, and the friction coefficient in the lateral direction is increased. If the holding bodies are arranged vertically, it is easy to release the force in the lateral direction, and it will come off only by the elasticity of the material. In order to prevent this and obtain a strong fixing force, it is most desirable to provide each holding body horizontally. That is because the two holding bodies are connected and supported, and the horizontal arrangement can be maintained.

  Since a large amount of cotton 12 is confined between two arcuate pinching bodies, large pressure and friction are produced when the cotton 12 is moved.

  Also, the friction is increased by curving the two holding bodies against the force in the vertical direction. If it is linear like tweezers, the force is easily lost in the linear direction, and it will come off only by the elasticity of the material. If the two sandwiching bodies facing each other are curved, the A portion produces a C-shaped frictional effect as shown in FIG.

  If you compare it with skiing, it can be said that the Bogen and C-shape are the same principle as stopping by friction rather than direct downhill. Even when observed in the experiment, it was confirmed that the blanket 11 bite into the same place and it was difficult to come off for a long time.

  In terms of the force in the direction of rotation, it has been found that when an external force such as turning over is applied as shown in FIG. 11, the tip gradually begins to rotate toward the pillow in about a week. Therefore, although not shown in the drawings, the rotation of the holding body can be prevented by forming a wave shape or a groove shape, or by using a heart-shaped holding body as shown in FIG. This is because the shape bites into the bristle of the blanket 11 and a gripping force in the rotational direction is generated, and it can be confirmed that the shape can be fixed for more than two weeks.

  In addition, when viewed from the direction of the clamping force on the outside and inside, arc-shaped springs are urged on both sides of the tip and end of each holding body, so it is far more than tweezers with only one side of the spring. It is configured to produce a powerful holding force.

  From the above, a shape configuration that exhibits not only the elasticity of the material but also the friction characteristics between the futon and the wire is added, and strong fixation can be realized for a long time.

  Next, means for fixing the futon etc. from the bed etc. by using the futon fixing tool 1 will be described.

  After fixing the futon 10 and the blanket 11, the slip-preventing belt 13 can be attached to the belt mounting opening 9 as shown in FIG. The slip-off prevention belt 13 connected to the futon fixing tool 1 can be connected to a part of the bed or connected through the back side of the mattress to prevent the futon 10 and the blanket 11 from slipping off from the bed or the like. It is not always necessary, and it can be used so that the physically handicapped will not fall asleep.

  Although partially described above, as shown in FIG. 13, the shape is a heart shape from the inner holding body 3 to the inner holding body tip 5. As a result, the friction in the rotation direction is strengthened, and it is possible to prevent the friction from being removed while rotating little by little.

  A heart-shaped depression or protrusion is dangerous if it is too sharp.

  If it is a heart shape, it becomes a little wider in the horizontal direction, but the other configurations are the same as those described in the embodiment of the invention. 14 to 16 are reference drawings showing the side surfaces and the like.
