Description

[Detailed description of the invention] [Industrial application field] The present invention locks the corners of a sheet that is attached to the corners of a futon or a pine mattress and covers the upper surface thereof,
The present invention relates to a sheet corner for preventing the sheet from peeling off or shifting.

[Prior Art] In general, in order to prevent a futon or pine tress from getting dirty due to a baby's bedwetting, the top surface of the futon or pine tress is often covered with a waterproof sheet that has a waterproof surface. It is being said.

However, waterproof sheets generally have a high frictional resistance on the surface due to their waterproofing, so when the baby turns over, the waterproof sheet clings to his body, causing the waterproof sheet to shift. The futon or pine tresses were often exposed.

Therefore, in the past, a waterproof sheet placed on a futon or pine tress was covered with an ordinary sheet along with the futon or pine tress, and the four sides of the sheet were folded over the back of the futon or pine tress, so that the sheet would be covered by the weight of the futon or pine tress. The folded part is pressed. As a result, ordinary sheets with relatively low surface frictional resistance were brought into contact with the baby, preventing the waterproof sheet from shifting due to turning over and suppressing stains on the futon or mattress.

[Problem to be solved by the invention] However, in the case of such conventional means for suppressing stains on futons, etc., the waterproof sheets were covered with ordinary sheets, which caused problems when the baby slept on the bed. There was a problem that if the waterproof sheets got dirty, the regular sheets would inevitably get dirty as well.

The present invention has been developed in view of such conventional problems, and has a structure in which the corners of the sheet are locked to the corners of the futon or pinerest, so that the sheet will not shift even when the baby turns over in bed. The aim is to solve the above problems.

[Means for Solving the Problems] In order to achieve the above object, the sheet corner of the present invention has an upper surface piece and a lower surface piece that are arranged substantially parallel to each other with a gap corresponding to the thickness of the futon or pine mattress. Alternatively, a corner holding part is provided into which the corner of the pinerest is inserted, and a locking part is provided on the upper surface or the lower surface of the upper surface piece to be able to lock the corner of the bed sheet covering the upper surface of the futon or the pinetress. It is said that

[Function] The present sheet corners are individually attached to the four corners of, for example, a rectangular futon or mattress, and the four corners of the sheet are locked by locking portions provided on the top pieces of the sheet corners. As a result, even if you turn over inside the sheets, the sheets will be stretched from all sides and placed on top of the futon or pine mattress, so the sheets will not shift or peel off as you turn over. Never.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention.

First, to explain the configuration, 1 in the figure is a top piece, 2
is a lower surface piece, the upper surface piece 1 has a trapezoidal shape, and the lower surface piece 2 has a trapezoidal part similar to the upper surface piece 1 at one end, and a pressure receiving part expanded widely at the other end to receive the pressing force from above. 2a is formed.

The upper piece 1 and the lower piece 2 are formed almost parallel to each other with a gap corresponding to the thickness of the pinerest 5 (or futon) by two side pieces 3 and 4 that connect the sloped parts of the trapezoid. . 2 side pieces 3, 4
are arranged so that their extension lines in the planar direction intersect at an angle of 90 degrees, and the corners of the pinerest 5 are inserted inside these top piece 1, bottom piece 2, and side pieces 3 and 4. A corner holding portion 6 is formed.

Further, on the lower surface of the upper surface piece 1, that is, on the inner upper surface of the corner holding part 6, one fastener piece 7 of a surface fastener, which is a specific example of a locking part, is fixed. and,
As shown in FIG. 2, the other fastener piece 8 of the hook and loop fastener is attached to the upper surface of the four corners of a sheet 9 formed to have approximately the same size as the rectangular pinerest 5.

As the material for the sheet corner having the above configuration, it is preferable to use a material that can be set into a certain shape by attaching the mattress 5, such as cloth or soft synthetic resin material.

Further, as the sheet 9, it is preferable to use a waterproof sheet that has been waterproofed on at least one side, but it goes without saying that a normal sheet can be used.

Next, the effect will be explained.

FIG. 2 is a diagram showing the usage state of this embodiment,
Normally, four sheet corners A are used for one rectangular pinerest 5.

First, by inserting the four corners of the mattress 5 into the corner holding parts 6 of each sheet corner A, a total of four sheet corners A are attached, one at each of the four corners. After that, each of the four corners of the sheet 9 is inserted into the corner holding part 6, and the sheet 9 is
The sheet 9 is laid on the mattress 5 by engaging the fastener pieces 8 provided on the upper surface of each corner of the sheet corner A with the fastener pieces 7 provided on the lower surface of the upper surface piece 1 of the sheet corner A.

When the baby lies down on such a bed, the sheet 9 and the pinerest 5 sink due to the baby's weight, and the sheet 9 is pulled inward. However, in this embodiment, the sheet 9
The four corners of the sheet are pressed and supported by the corner holding parts 6 of the four sheet corners A, and furthermore, they are locked by the locking parts and pulled outward, so even if the red sheets sink, The sheet 9 does not shift, and it is possible to reliably ensure that the sheet 9 covers the upper surface of the mattress 5.

In this state, even if the baby turns over and a large lateral tensile force is applied to the sheet 9, the sheet 9 will be firmly locked at the four corners by the four sheet corners A. Therefore, the sheet 9 does not shift, and the upper surface of the mattress 5 is covered by the sheet 9.

In addition, a pressure-receiving part 2a is formed on the bottom piece 2 of the sheet corner A, and this part receives pressure from the weight of the baby lying down, which creates a gap between the bed and the tatami mat, floor, etc. The generated frictional force prevents the sheet corner A from slipping. Therefore,
This pressure receiving portion 2a works in cooperation with the corner holding portion 6, and can reliably prevent the sheet corner A from coming off from the corner of the mattress 5.

In addition, when the sheet 9 is made of pile fabric, it itself has the function of one of the fastener pieces 8, so in this case, the fastener piece on the sheet side becomes unnecessary.

3 and 4 show other embodiments of the present invention.

In this embodiment, one fastener piece 7 is fixed to the upper surface of the upper face piece 1 of the sheet corner A in the above embodiment, that is, the outer surface of the corner holding part 6, and the other fastener piece 8 is fixed to the four corners of the sheet 9. It is attached to the bottom surface. Therefore, in this embodiment, the entire surface of the mattress 5 and the sheet corner A is covered with the sheet 9.

Other configurations and functions are the same as those in the previous embodiment,
Even with such a structure, it is possible to obtain the same effects as in the above embodiment.

In addition, in the above embodiment, an example was explained in which the sheet corner A was attached to the corner of the pinerest 5, but the present invention is not limited to this, and the same effect can be obtained even if the sheet corner A is attached to the corner of the futon. Obtainable. Furthermore, although an example of use in a baby's futon or pine mattress has been described, it can of course be used in an adult's bed, and is particularly suitable for use in the bed of a bedridden elderly person or a sick person.

Further, in the above embodiment, an example in which a hook-and-loop fastener is used as the locking portion has been described, but various locking means such as a hook or a button may be used.

[Effect of the invention] As explained above, in the sheet corner of the present invention, the upper surface piece and the lower surface piece are arranged in parallel to provide a corner holding part, and the sheet locking part is provided on the upper surface or the lower surface of the upper surface piece. Because of this structure, even when a lateral force is applied to the sheet due to a baby turning over, etc., it is possible to reliably prevent the sheet from shifting or peeling off from the pinerest or the like. Therefore, by reliably covering the top surface of the futon or pine tress on which the baby is lying, with a sheet, it is possible to prevent the futon or pine tress from becoming soiled and to keep the futon or the like clean.
Since the number of dirty sheets can be reduced compared to the conventional method, it is possible to provide a highly practical sheet corner in which the number and number of times the sheets are washed can be reduced.
