Description

Bath slippers for non-slip {Non-slip slippers}

The present invention relates to a slipper for a bathroom, and more particularly, to a slipper for a bathroom for preventing slipping with a wet floor in a bathroom or a home bathroom.

Bathrooms and home bathrooms often have water on the floor. Therefore, slippers used in bathrooms or home bathrooms must have a non-slip structure or have a non-slip agent that can prevent slipping. In particular, in the case of a child with insufficient caution or an agile elderly person, it is a situation that slips in the bathroom and suffers serious injury, and a bathroom slipper having a structure for preventing slipping is required.

The pre-registered utility model No. 20-0305810 relates to a slipper for a bathroom, wherein a body portion on which a user's foot is seated is formed, and a footrest portion that can be fixed by fitting the foot seated on the body portion is coupled to the upper end of the body, An anti-slip groove is formed on the bottom surface of the body portion to prevent the user from slipping in a wet bathroom. When the user wears the slippers, the user's feet are sandwiched between the toes of the body, so that the slippers can be used.

However, the problem with the slippers for bathrooms is that the user has always had to wear slippers in one direction because the foot / toe parts are formed on the upper front end of the body, and it is very difficult and uncomfortable to use them on the toes. There was a problem in that the body part had to be slanted on the wall or the like in a state where the foot sandwiched between the body part and the footrest part was removed in order to remove water remaining on the body part. In addition, when the slippers are continuously used, there is a disadvantage that the toe is frequently injured by the foot portion due to the continuous friction between the foot portion and the toe.

 On the other hand, in the pre-registered utility model registration No. 433240, a washing brush is provided at the front side of the bottom surface of the floor member of the bathroom slippers, and a bathroom slipper provided with a rubber blade for removing water is provided at the middle and back sides of the bottom surface of the floor member It is done. The slippers for the bathroom can be cleaned by rubbing the bathroom floor with a washing brush provided on the floor member while the user wears the slippers, and also a slipper can be prevented by removing the remaining water on the bathroom floor with a rubber blade for removing moisture. It has the advantage that it can be used when the cleaning brush or rubber blade is worn. The slippers are slippers for the purpose of cleaning the bathroom floor rather than for the purpose of preventing slippage, and the structure such as the fact that a washing brush should be formed and a rubber blade should be formed is very complicated. In addition to the disadvantages of being complicated and easy to be damaged due to its weak durability, there was a disadvantage that the anti-slip function was very weak.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a slipper for a bathroom to prevent slipping according to a preferred embodiment of the present invention, and FIG. 2 is a side view of a slipper for a bathroom to prevent slipping according to a preferred embodiment of the present invention.

Referring to Figures 1 and 2, the slipper for a bathroom slipper 100 of the present invention is a body 20 corresponding to the bottom plate of the slipper, the both sides are coupled to the body cover 10 covering a part of the body And a non-slip layer 30 formed on the bottom surface of the body to prevent friction by generating friction with the bathroom floor.

The body 20 generally has a streamlined structure similar to the sole structure, and has various sizes according to the size of the wearer's feet. Generally, slippers having a body slightly longer than the size of the wearer's foot are used.

The material of the body 20 is generally a thermoplastic resin material is used, in particular, soft PVC, EVA materials, etc. are widely used, but of course not necessarily limited to this. Of course, in addition to the subject of the thermoplastic resin, various additives such as UV stabilizers (ultraviolet stabilizers), antioxidants, thermal stabilizers, and fillers can be used.

Although not shown, the upper surface of the body 20 may be formed with a plurality of projections for acupressure for acupressure, or a plurality of guide guide protrusions, etc., for enhancing the friction between the slippers and the soles and improving the fit. Of course. In addition, the body may be formed in a plurality of through-holes in order to be used in a bathroom or a bathroom, to smoothly discharge water from the upper surface of the body.

The cover 10 is a portion that is coupled to both sides of the body to cover a part of the body. The cover is a part where the wearer's foot is caught, and is an essential component that allows the user to wear slippers.

The cover 10 may be integrally formed during injection molding of the body, or after the body and the cover are separately molded, both ends of the cover are inserted into grooves capable of inserting both sides of the cover on the side of the body. Therefore, it may be formed by bonding with an adhesive. In general, when the material of the cover and the material of the body are different, a method of bonding with an adhesive is used. However, when the material of the cover and the material of the body are the same, they are manufactured by being integrally combined during injection molding.

The material of the cover is also a thermoplastic resin is used, in particular, soft PVC, EVA materials, etc. are widely used, of course, not necessarily limited to this. Also, of course, various additives may be used.

The anti-slip layer 30 is formed on the bottom surface of the slipper body. The anti-slip layer 30 is a portion attached to the bottom surface of the body in order to prevent slip in the bathroom or bathroom, and includes plastic resin and stone powder particles. The anti-slip layer 30 has a shape in which stone powder particles are evenly dispersed in the plastic resin. The stone powder particles generate friction with the floor of the bathroom or bathroom, thereby acting as a non-slip agent to prevent slipping.

Stone powder particles have a granular form and can be used in various types or sizes, but should not be easily separated from the plastic resin during friction with the bathroom or bathroom floor, and must have a strong strength that is not easily broken for this purpose. The size of the stone dust particles is about 6 to 10 mesh. If the particle size is smaller than 10 mesh, it may not function as a non-slip agent, and if the particle size is smaller than 6 mesh, there is a risk of easy separation from the plastic resin.

Preferably, the stone powder particles include at least one of abrasive particles and blue-green particles. However, the type of the stone powder particles is not necessarily limited to this, and it is possible to apply the stone powder particles of the hard particle type, which are not easily broken, rather than the powder type.

As the abrasive grain particles, a material used for a polishing grinder is manufactured and sold in a particle form, but the abrasive grain size is about 6 to 10 mesh (preferably 8 mesh). Since the abrasive grains have very strong strength, they are preferred as non-slip agents.

The blue-green particles mean stone particles having blue light, and have a particle size of about 6 to 10 mesh (preferably about 8 mesh) in the same manner as the abrasive grain size. Cyanite particles also have a very strong strength and can be preferably used as a non-slip agent.

Preferably, abrasive particles or blue-green particles, or a mixture of abrasive-particles and blue-green particles is used, but is not necessarily limited thereto, and is not easily separated from plastic resin, and stone powder particles that are not easily broken are used as a non-slip agent. It is possible.

As the plastic resin of the anti-slip layer, a thermoplastic resin is used, and particularly, soft PVC, EVA materials, etc. are widely used, but it is needless to say that it is not necessarily limited to this. As described above, as the additive of the anti-slip layer, various additives can be used.

Although not shown, if a through hole for draining water is formed in the body, a through hole must be formed in the anti-slip layer corresponding to the through hole. The through-holes for draining the body and the through-holes in the anti-slip layer must coincide to allow the body to drain smoothly from the slippers.

On the other hand, preferably, the anti-slip layer preferably has a stone flour particle attendance rate of 40% to 60%. The attendance rate of the stone dust particles means the rate at which the stone dust particles are exposed on the surface of the anti-skid layer. That is, a high attendance rate means that the stone dust particles are exposed to the surface of the anti-skid layer, and a low attendance rate means that the stone dust particles are exposed to the surface of the anti-skid layer. The attendance rate of the stone powder particles of the anti-skid layer of the present invention is preferably 40 to 60%, whereas when the attendance rate is less than 40%, the proportion of the stone powder particles used as a non-slip agent is low, whereas the anti-slip function cannot be smoothly performed. When the attendance rate is more than 60%, there is a disadvantage that the binding force with the plastic resin is weak, so that the stone powder particles can be easily separated from the plastic resin.

3 is a side view of a slipper for a bathroom to prevent slipping, according to another preferred embodiment of the present invention.

Referring to FIG. 3, the embodiment of FIG. 3 shows a case where the anti-slip layer is formed in two stages. That is, the anti-slip layer 30 is divided into a first anti-slip layer 32 exposed on the lower bottom surface of the slipper and a second anti-slip layer 34 formed on the first anti-slip layer. The second anti-slip layer 34 is not exposed on the lower bottom surface of the slipper, but corresponds to a portion that presses the first anti-slip layer so that the first anti-slip layer performs the anti-slip function more smoothly. That is, the first anti-slip layer is a portion for preventing slip through friction with the floor of the bathroom, and the second anti-slip layer is a portion for pressing the first anti-slip layer by pressing it with a stronger force by the user's weight.

To this end, the particle size of the second stone powder particles 44 formed on the second anti-skid layer has a larger size than the particle size of the first stone powder particles 42 formed on the first anti-skid layer.

The body of the slipper has a soft cushioning property, not a hard material, so the stone dust particles may have limitations in exerting the function of a non-slip agent. To prevent this, a second anti-skid layer having a second particle size (44) having a larger particle size (particle size) than the first anti-skid particle particle 42 is inserted in the middle to prevent the first anti-skid layer. By forming the second anti-slip layer having a stiffer and stronger stiffness, the second anti-slip layer can be pressed against the user's weight, thereby improving the anti-skid function of the first anti-slip layer. The stone powder particles of the second anti-slip layer have a larger size than the stone powder particles of the first anti-slip layer, which is more stiff, and thus can transmit a higher pressing force to the first anti-slip layer than the soft slipper body.

If the size of the first stone dust particles of the first anti-skid layer is 6 to 10 mesh, the size of the second stone dust particles of the second anti-skid layer is appropriate to 4 to 6 mesh. Although not shown, in some cases, a third anti-skid layer may be formed on the second anti-skid layer, including a third stone dust particle of a particle larger than the size of the second stone dust particles of the second anti-skid layer. to be.

Figure 4 is a flow chart for explaining the manufacturing process of the slippers for the bathroom to prevent slipping, according to a preferred embodiment of the present invention.

4, the manufacturing process of the slippers for the bathroom to prevent slipping of the present invention is as follows.

First, plastic resin and stone powder particles are prepared (S10). As the plastic resin, a thermoplastic resin such as soft PVC or EVA can be used. The stone powder is not a powder, but a particle type such as a grain is used, and a particle type having a strong strength that is not easily broken is prepared. The stone powder particles are preferably abrasive grains or blue-green particles, and abrasive-grain particles and blue-green particles may be used in combination.

The plastic resin is put in a stirrer or the like, followed by heating and stirring (S20). The plastic resin sold in general is in the form of pellets, and should be changed to a liquid form having flowability by heating it. To this end, it is placed in a device such as a stirrer and stirred for heating. Of course, various additives such as UV stabilizers (ultraviolet stabilizers), antioxidants, heat stabilizers, fillers, and pigments can be used as additives when heating and stirring plastic resins.

The prepared stone powder particles are added to the heated and stirred plastic resin (S30). Rather than the method of injecting large amounts of stone powder at a time, a small amount is slowly injected while stirring the plastic resin. If a large amount is added at once, the quality of the product may be poor because the stone powder particles do not evenly disperse and stick together. To prevent this, a small amount should be added slowly and stirring continued.

When the stone powder particles are sufficiently dispersed without being entangled in the plastic resin, a sheet-type anti-slip layer is produced by roller pressing (S40). That is, by installing a roller on the outlet side of the stirrer to squeeze the plastic resin containing the stone dust particles discharged from the stirrer, a sheet type anti-slip layer is produced. This follows the method of producing plastic resin in sheet type, which is generally widely used.

The sheet type anti-slip layer is pressed into the shape of a slipper sole-shaped non-slip layer in consideration of the size (S50). That is, by using a press machine, the anti-slip layer is cut into the shape of a slipper sole by size.

The anti-slip layer in the shape of a slipper sole manufactured in this way is attached to the bottom surface of the slipper body (S60). There are two main ways in which the slipper body is attached to the bottom surface of the slipper layer. One method is to first insert a slipper-shaped anti-slip layer into the injection molding machine for making the slipper body, and then pour resin to make the slipper body on it to form the slipper body and non-slip layer integrally. This is a method of attaching the anti-slip layer to the bottom surface of the slipper body using adhesive after preparing the slipper body and the anti-slip layer, respectively. Both of the above two methods can be used, but the method of attaching using adhesive is a method of attaching the slipper body and the anti-slip layer with adhesive. It will be said that the former method of integrally forming is more preferable. However, it is not necessarily limited to this.

The method of forming the anti-skid layer as shown in FIG. 3 in two layers is formed by separately forming the plastic resin layer in which each stone powder particle is dispersed, and then the sheet-type anti-skid layer is brought into close contact with each other at the time of manufacture, so that the two-layer sheet type slip After manufacturing the anti-slip layer with the prevention layer integrated, it can be used by cutting it through a press machine like the shape of a slipper sole.

5 is a perspective view of a slipper for bathrooms to prevent slipping according to another preferred embodiment of the present invention, and FIG. 6 is a side cross-sectional view of a slipper for bathrooms to prevent slipping of FIG. 5.

The slippers of FIGS. 5 and 6 are non-slip layers, and are slippers of a linear type having a specific shape.

The bottom surface of shoes or slippers is largely divided into three types. That is, it is divided into a front bottom portion, a central arch portion, and a rear bottom portion. This is due to the structure of the human foot, which is classified based on the arch of the foot. The central arch portion will be referred to as a portion corresponding to the arch portion of the sole, the front bottom portion will correspond to the front portion of the sole, and the rear bottom portion will be referred to as the portion corresponding to the back portion of the sole.

Preferably, as shown in Figure 5, the triangular wave-shaped non-slip layer 30 is formed on the bottom surface of the front and bottom surfaces except for the central arch among the bottom surfaces of the slippers. This is because, even if a non-slip layer having a triangular wave shape is formed in the central arch portion, since a human load is not applied to the central arch portion, only a large amount of material is required and the anti-slip effect is considerably low. Therefore, in consideration of cost aspects such as material cost and production cost, and work efficiency, it is preferable to form a non-slip layer having a triangular wave shape only on the front bottom surface and the rear bottom surface.

In FIG. 5, the non-slip layer is formed on the front bottom surface and the rear bottom surface, respectively, excluding the central arch portion among the bottom surfaces, and a plurality of triangular wave linear shapes are formed. The shape of the triangle wave is to perform the anti-slip function more effectively than the straight shape. The anti-slip layer having a triangular wave shape can effectively prevent slipping from side to side.

Referring to FIG. 6, the linear type anti-slip layer is formed to protrude from the bottom surface of the body. This is to further increase the anti-skid function. This is to improve the anti-slip function by increasing the friction with the bathroom floor by forming the anti-slip layer to protrude rather than flat with the bottom surface of the body.

Preferably, the protrusion direction of the anti-slip layer formed on the front bottom surface and the protrusion direction of the anti-slip layer formed on the rear bottom surface are formed opposite to each other. That is, the anti-slip layer formed on the front bottom surface is formed obliquely in the front direction of the body bottom surface, and the anti-slip layer formed on the rear bottom surface is formed obliquely in the rear direction of the body bottom surface. This is for the anti-slip layer formed on the front bottom surface to face the bathroom bottom surface and the anti-slip layer formed on the rear bottom surface opposite to the bathroom bottom surface. Accordingly, the slippers are not easily slid in the forward direction, and the slippers are not easily slid in the backward direction, thereby preventing slippage in the forward and backward directions.

Here, the attendance rate of the stone powder particles of the anti-slip layer is preferably 40 to 60%. The anti-slip layer formed on the front bottom surface and the anti-slip layer formed on the rear bottom surface preferably have a stone powder particle attendance rate of 40 to 60%. When the attendance rate is less than 40%, the proportion of stone powder particles used as a non-slip agent is low, so that the anti-slip function cannot be performed smoothly, whereas when the attendance rate is more than 60%, the binding force with the plastic resin is weak and easily separated from the plastic resin. It has the disadvantage that it can be.

Although the embodiments of the present invention have been described with reference to the above and the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can implement the present invention in other specific forms without changing its technical spirit or essential features. You will understand that there is. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive.
