Description

slippers {SLIPPERS}

The present disclosure relates to slippers, and specifically to interfloor noise prevention slippers.

In recent years, noise between floors in apartment buildings, multi-purpose spaces, or officetels has emerged as a social problem. In general, the inter-floor noise means that the floor impact sound generated from the upper floor is transmitted to the lower floor and causes damage. In particular, in the case of infants, since they are still immature to require attention in relation to walking, the floor impact sound may be louder due to actions such as running. Of course, in the case of adults as well, if you walk a little carelessly, floor impact sound can be generated any number of times.

According to KS F 2810-1, 2 and KS F 2863-1, 2, standards for domestic floor impact sound measurement and evaluation methods, light impact sound (2863-1, 125Hz~2000Hz) and heavy impact sound (2863-2, 63Hz - 500Hz). In general, the light impact sound belongs to the low frequency band, and the heavy impact sound may be divided into the high frequency band.

However, since the floor impact sound generated by a child's walking includes both low frequency and high frequency band impact sounds, both light impact sound and heavy impact sound should be prevented in reality.

On the other hand, many homes are equipped with mats for preventing noise between floors so that the floor impact noise generated by the walking of these infants can be minimized. However, the noise prevention mat between floors is bulky, and since it exists in a fixed position, it may be somewhat insufficient to prevent noise between floors caused by infants walking around.

Accordingly, there is a demand for slippers capable of preventing noise between floors.

However, since the above-described components are not essential in implementing the bottom part 200 , the bottom part 200 may have more or fewer components than those listed above.

The first layer 210 may be formed of a first material that absorbs noise energy. Here, the noise energy may be energy related to all noises, such as pressure energy generated while a person runs or sound energy generated while coming into contact with a hard floor. However, the present invention is not limited thereto.

Meanwhile, in the present disclosure, the first material of the first layer 210 may be a material capable of acting as a sound absorbing agent for absorbing noise energy.

For example, the first material may be a PU (polyurethane) material. However, the present invention is not limited thereto.

On the other hand, when the first material is a PU material, the first layer 210 may deliver an appropriate cushioning feeling to the user. That is, the first layer 210 may be located at the top of the bottom part 200 so that the user can feel comfortable when wearing the slippers 1000 . However, the present invention is not limited thereto.

Meanwhile, the second layer 220 may be made of a second material that reduces a weight impact sound. Here, the weight impact sound may be an impact sound belonging to a frequency band of 63 Hz - 500 Hz according to the standards for the domestic floor impact sound measurement and evaluation method. However, the present invention is not limited thereto.

Meanwhile, in the present disclosure, the second material of the second layer 220 is a material that absorbs the noise energy that is not absorbed in the first layer 210 and performs a sound insulation function so that it is not transmitted to the third layer 230 . can

For example, the second material may be a PE (polyethylene) material.

Specifically, the second material of the second layer 220 may be a PE material having a density of 0.941 g/cm ³ or more based on the density. However, the present invention is not limited thereto.

Meanwhile, the third layer 230 may be made of a third material that reduces light impact sound. Here, the light impact sound may be an impact sound belonging to a frequency band of 125 Hz to 2000 Hz according to the standards for the domestic floor impact sound measurement and evaluation method. However, the present invention is not limited thereto.

Meanwhile, in the present disclosure, the third material of the third layer 230 may be a material that is positioned on the surface of the slippers 1000 in contact with the floor, has good durability and can quickly absorb a floor impact sound.

For example, the third material may be a polyvinyl chloride (PVC) material. However, the present invention is not limited thereto.

Meanwhile, according to some embodiments of the present disclosure, thickness ratios of the first layer 210 , the second layer 220 , and the third layer 230 may be different.

Specifically, a thickness ratio of the first layer 210 , the second layer 220 , and the third layer 230 may be 1:2:1. That is, the second layer 220 may be twice as thick as each of the first layer 210 and the third layer 230 .

For example, the thickness of the first layer 210 may be 5 mm. Also, the thickness of the second layer 220 may be 10 mm. Also, the thickness of the third layer 230 may be 5 mm.

As another example, the thickness of the first layer 210 may be 10 mm. Also, the thickness of the second layer 220 may be 20 mm. Also, the thickness of the third layer 230 may be 10 mm. However, the present invention is not limited thereto.

Meanwhile, according to some embodiments of the present disclosure, the thicknesses of the first layer 210 , the second layer 220 , and the third layer 230 may be the same. In addition, each of the first layer 210 and the third layer 230 may be provided one by one, and the second layer 220 may be provided with two. However, the present invention is not limited thereto.

On the other hand, the slippers according to the present disclosure may be somewhat lighter than the conventional slippers.

Specifically, each of the first layer 210 , the second layer 220 , and the third layer 230 may include an air cell structure for absorbing an impact. In this case, the weight per area of each of the first layer 210 , the second layer 220 , and the third layer 230 may be slightly less than that of a conventional sound absorbing or insulating material. In this case, the weight of a pair of slippers according to the present disclosure may be 60 g. Accordingly, the slippers according to the present disclosure may provide a user with a comfortable fit.

As an example, slippers may be 60 g per pair based on a size of 150 mm, which is a general children's shoe. As another example, the slippers may be 60g per pair based on the 160mm size. However, the present invention is not limited thereto.

Meanwhile, according to some embodiments of the present disclosure, the second layer 220 may be disposed between the first layer 210 and the third layer 230 . In addition, the second layer 220 may perform a sound insulation function that blocks transmission of noise energy that is not absorbed in the first layer 210 to the third layer 230 . However, the present invention is not limited thereto.

Meanwhile, according to some embodiments of the present disclosure, the first layer 210 may be provided at the top of the bottom part 200 . In addition, the second layer 220 may be provided below the first layer 210 . In addition, the third layer 230 may be provided below the second layer 220 . As described above, as the first layer 210, the second layer 220, and the third layer 230 are sequentially formed, the bottom 200 is not broken even by the user and the impact generated from the outside and the shape is maintained. can

Specifically, the first material of the first layer 210 may be a material having a light and excellent cushioning feeling. And, the first material can absorb a small impact transmitted to the user's bare feet. However, since the first material has low durability to be located at the lowermost end of the bottom part 200, it may be difficult to maintain its shape when grounding with the floor occurs. In addition, the first material may absorb the initial impact generated by the user, but may not absorb the heavy impact sound. Accordingly, the first layer 210 may be provided at the top of the bottom part 200 . In this case, the first layer 210 may serve as a sound absorbing material for absorbing noise energy, providing a soft cushioning feeling and tactile sensation for bare feet, and maintaining the shape of the slippers 1000 by maintaining the shape. .

Meanwhile, the second material of the second layer 220 may have a light and hard cushioning feeling. For example, the second material may have a density of 0.941 g/cm 3 or more based on the density. In this case, since the second material has high tensile strength, shape maintenance may be possible. In addition, the second material may serve to catch the weight impact sound generated by the user. For example, the second material may prevent the weight impact sound from being pushed out of the second layer and transmitted when the weight impact sound is applied. However, the second material may be harder than the first material and the third material in order to perform these sound absorption and sound insulation functions. If the second layer 220 is located at the top of the bottom part 200 , a satisfactory cushioning feeling may not be provided to the user. In addition, when the second layer 220 is located at the lowermost end of the bottom part 200 , an impact sound due to an impact with the floor may be further generated. Accordingly, the second layer 220 may be provided between the first layer 210 and the third layer 230 .

Meanwhile, the third material of the third layer 230 may have an intermediate level of durability and restoring force between the first material and the third material so that the shape of the bottom part 200 can be maintained even in impact with the floor. Accordingly, the third layer 230 may be located at the lowermost end of the bottom part 200 . In addition, the third layer 230 may serve to rapidly absorb the impact energy transmitted from the body load by being located on the surface in contact with the floor. In addition, the third material can maintain the shape of the slippers can be maintained.

As such, the bottom 200 according to the present disclosure may include a noise reduction layer formed in order of the first layer 210 , the second layer 220 , and the third layer 230 . Accordingly, the bottom part 200 can reduce noise generated by the user while maintaining the shape. However, the present invention is not limited thereto.

On the other hand, since the slippers according to the present disclosure do not have a rigid structure like sneakers, when a child runs while wearing the slippers, the sole may be compressed and cause a problem in that the ankle is bent. Accordingly, according to some embodiments of the present disclosure, the thickness of the noise reduction layer may be 20 mm to 30 mm. However, the present invention is not limited thereto.

Meanwhile, according to the above-described configuration, the first material, the second material, and the third material may be different materials. In this case, the first material, the second material, and the third material may have different hardnesses.

Specifically, the first material may have a first hardness. In addition, the second material may have a second hardness greater than the first hardness. That is, the first material of the first layer 210 may have a first hardness that is lower than that of the second material in order to provide a user with a satisfactory cushioning feeling. However, the present invention is not limited thereto.

Meanwhile, the third material may have a third hardness greater than the first hardness of the first material and smaller than the second hardness of the second material. That is, the third material of the third layer 230 may have a hardness so that an initial impact generated by the slipper 1000 and the floor can be smoothly absorbed. However, the present invention is not limited thereto.

Meanwhile, the first outer skin 240 may cover at least a portion of the upper portion of the noise reduction layer. Here, the noise reduction layer may be a layer including the first layer 210 , the second layer 220 , and the third layer 230 .
