Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cushion for headbands, and more particularly to a cushion for headbands which is provided with a vacant space having a cushion cover shape or an air tube formed integrally with a cushion cover at the rear part of a headband connected to one selected from safety appliances including a welding mask, a protective mask, a safety helmet and a medical device used in industrial fields or medical operations, to provide excellent cushion feeling when contacting a wearer's head during wearing, to have a flexible shape regardless of a shape of the wearer's head, and thus not to generate inconvenience even when the cushion for headbands is worn for a long time.

2. Description of the Related Art

In general, a headband installed in on each of a welding mask, a protective mask, a safety helmet used in industrial fields and a medical device is formed of a synthetic resin to fix the mask, helmet or device to a wearer's head, and thus a wearer may wear the mask, helmet or device by the headband in a manner in which the headband surrounds the wearer's head.

The headband connected to a welding mask, a protective mask or a safety helmet does not form various contact areas with the wearer's head according to a shape of the wearer's head, thus causing discomfort in wearing.

In order to solve such a drawback, a pad may be installed on the headband. The conventional pad is in the type of a fixed cushion formed of a foamed material, and such a fixed cushion is limited in flexible adaptation to all shapes of heads although excellent cushion force may be provided.

Further, a cushion for headbands is connected to the rear surface of the headband so as to adjust the length of the headband according to a size of the wearer's head. Even if the conventional pad contacting the rear part of the wearer's head is formed of a material having high elasticity, the pad maintains identical cushion force (repulsive force) in a designated direction, and thus does not flexibly cope with the sizes or shapes of the individuals.

SUMMARY OF THE INVENTION

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a cushion for headbands which provides excellent cushion feeling to a wearer when contacting the wearer's head during wearing and does not cause inconvenience even when the cushion for headbands is worn for a long time.

In accordance with the present invention, the above and other objects can be accomplished by the provision of a cushion for headbands which is connected to the rear surface of a headband such that the length of the headband connected to a welding mask, a working helmet, a safety mask, a protective mask or a medical device may be adjusted according to the size of a wearer's head, includes a connection case provided with a space recess formed on the rear surface thereof and fixing protrusions formed at the edge of the rear surface thereof, and a cushion cover provided with fixing grooves formed at the edge of the rear surface thereof so as to be connected to the connection case, so that a space having the shape of an air cushion cover may be formed between a pad of the cushion cover and the space recess of the connection case when the fixing grooves of the cushion cover are connected to the fixing protrusions of the connection case.

In a cushion for headbands in accordance with the present invention, a cushion cover 50 is formed in the shape of one selected from an oval pad, a protruding pad and a radial-shaped pad. Further, in the cushion for headbands in accordance with the present invention, the cushion cover 50 has a vacant space structure and is provided with fixing grooves 52 formed at four side surfaces thereof, as shown in FIG. 7, and thus covers a connection case 20 so as to be connected to the connection case 20.

In the cushion for headbands in accordance with the present invention, through holes 54 are formed at a part of the cushion cover 50 contacting a wearer's head, thus forming vent holes through which external air is circulated.

In accordance with embodiments of the present invention, as shown in FIGS. 1 to 4, a cushion for headbands is connected to the rear surface of a headband 10 so that the length of the headband 10 connected to one selected from a welding mask, a protective mask and a safety helmet may be adjusted according to the size of a wearer's head. Here, a connection case 20 is connected to the cushion for headbands, the headband 10 and an adjustment band 30 are connected to both sides of the connection case 20, thereby allowing the length of the headband 10 to be adjusted according to the size of the wearer's head.

In accordance with embodiments of the present invention, as shown in FIGS. 4 to 8, in the cushion for headbands, a space recess 46 forming a vacant space is formed on the connection case 20, fixing protrusions 42, 42′, 44 and 44′ are formed at four side surfaces of the connection case 20, and thus the cushion cover 50 covers the connection case 20 so as to be connected to the connection case 20.

The cushion for headbands in accordance with the present invention, which is connected to the rear surface of the headband such that the length of the headband connected to a welding mask may be adjusted according to the size of the wearer's head, includes the connection case 20 provided with the space recess 46 having the shape of a curved surface and formed on the rear surface thereof and the fixing protrusions 42, 42′, 44 and 44′ formed at the edge of the rear surface thereof, and the cushion cover 50 provided with the fixing grooves 52 formed at the edge of the rear surface thereof and formed in the shape of a cushion pad so that a space having the shape of an air cushion cover may be formed between the pad of the cushion cover 50 and the space recess 46 of the connection case 20 when the fixing grooves of the cushion cover 50 are connected to the fixing protrusions 42, 42′, 44 and 44′ of the connection case 20.

That is, band insertion grooves 45 and 45′ are formed at the circumference of the front surface of the connection case 20 so that the headband 10 and the adjustment hand 30 may be inserted into the band insertion grooves 45 and 45′ from both sides of the connection case 20, the space recess 46 having the shape of a curved surface is formed on the rear surface of the connection case 20 so that when the cushion cover 50 is connected to the rear surface of the connection case 20, a space having the shape of the cushion cover 50 may be formed between the pad of the cushion cover 50 and the rear surface of the connection case 20, and the fixing protrusions 42, 42′, 44 and 44′ are formed at the edge of the rear surface of the connection case 20.

FIGS. 9 to 12 are views illustrating a detaching process of a cushion for headbands in accordance with one embodiment of the present invention. In order to separate the cushion for headbands from the headband 10, the cushion cover 50 is removed from the fixing protrusions 42, 42′, 44 and 44′ formed at the edge of the rear surface of the connection case 20, and in order to mount the cushion for headbands on the headband 10, the cushion cover 50 is connected to the fixing protrusions 42, 42′, 44 and 44′ formed at the edge of the rear surface of the connection case 20. As shown in FIGS. 9 to 12, when a wearer presses the center of the cushion cover 50 with the thumb while pulling the upper part of the cushion cover 50 with the forefinger, the cushion cover 50 may be easily removed from the connection case 20 in order of {circle around (1)}{circle around (2)}{circle around (3)}{circle around (4)}.

In a cushion cover 50-1 in accordance with another embodiment of the present invention, as shown in FIGS. 13 and 14, a space recess 46 having the shape of a curved surface is formed on the rear surface of the connection case 20 so that when the cushion cover 50-1 is connected to the rear surface of the connection case 20, a space having the shape of the cushion cover 50-1 may be formed between the pad of the cushion cover 50-1 and the rear surface of the connection case 20.

The cushion cover 50-1 is formed of one selected from the group consisting of elastic rubber, silicon, PVE, PE, PP and flexible urethane.

Further, fixing protrusions 52-1 which are inserted into fixing holes 42-1 of the connection case 20 are formed at the edge of the rear surface of the cushion cover 50-1, and when the fixing protrusions 52-1 of the cushion cover 50-1 are inserted into the fixing holes 42-1 of the connection case 20, the space having the shape of the cushion cover 50-1 is formed between the pad of the cushion cover 50-1 and the rear surface of the connection case 20. The cushion cover 50-1 is configured so as to form the space having the shape of the cushion cover 50-1. Since the cushion cover 50 is connected to the connection case 20, the cushion for headbands in accordance with the present invention provides excellent cushion feeling to a wearer when contacting the wearer's head and does not cause inconvenience even when the cushion for headbands is worn for a long time.

Further, in the cushion for headbands in accordance with the present invention, the cushion cover 50 may be formed in the shape of one selected from an oval pad, a protruding pad and a radial-shaped pad, so as to softly and comfortably contact the wearer's head if the wearer wears the headband.

In a cushion cover 50-1 in accordance with another embodiment of the present invention, as shown in FIG. 15, an air tube 50-2 is formed within a space having the shape of an air cushion cover between the cushion cover 50 and a space recess of the connection case.

In a cushion cover 50-1 in accordance with another embodiment of the present invention, as shown in FIG. 16, two air tubes 50-2 divided from each other by a diaphragm are formed between the rear surface of cushion cover 50-1 and a space recess of the connection case.

As shown in FIG. 19, a conventional rear cushion 100 for headbands is configured such that, when a wearer wears a welding mask with a headband having the cushion 100, the entirety of the cushion 100 is adhered to the wearer's head in the central direction, thus being not completely adhered to the wearer's head. On the other hand, as shown in FIGS. 17 and 18, in the case of the cushion 50 for headbands in accordance with the present invention, when a wearer wears a welding mask with a headband having the cushion 50, the center of the cushion 50 surrounds the wearer's head in the direction A and both edges of the cushion 50 are expanded in the direction B, and thus the cushion 50 may be completely adhered to the wearer's head.

As apparent from the above description, the present invention provides a cushion for headbands in which a rear cushion cover is connected to a connection case connected to one selected from a welding mask, a protective mask and a safety helmet, and a space recess having the shape of a curved surface or a plane surface is formed on the rear surface of the connection case so that a space having the shape of the cushion cover may be formed between a pad of the cushion cover and the rear surface of the connection case when the cushion cover is connected to the rear surface of the connection case, thereby providing excellent cushion feeling to a wearer when contacting the wearer's head and does not cause inconvenience even when the cushion for headbands is worn for a long time.
