The present invention relates to a constriction assembly, more particularly, to a device used in face or eye mask, as well as swimming, sport or work mask etc, for adjusting the degree of tightness so as to control the tightness of their headband.
As shown in
For example, the masks disclosed in U.S. Pat. Nos. 6,381,761 and 6,460,995B1 etc, all allow buckles to being evidently lying on both sides of the mask and at these positions the degree of tightness of headbands can be adjusted.
Operations on said configuration are very near the both sides of eye patch portion and it is not readily to operate simultaneously on both sides, so that problems, such as displacement of the eye patch portion and imbalance pressure often occur during operations. Therefore, try to improve operation manner and the configuration is an important task.
It is a primary object of the present invention to provide a constriction assembly of mask designed so that it is mounting on back of head etc, so as to have band easily provided on both sides of mask without the need to mount buckles having control and constriction function therein.
In order to achieve the above object the constriction assembly of the invention includes:
a casing seat formed into concave-shaped and having two opposite upward walls, an regulator held in the interior thereof and a base connecting a pad, wherein the upward walls having two opposite bores at the middle thereof for receiving protruding buttons of the regulator and two pairs of bores respectively at its both sides for mounting the tenon of turning body, and at its inside of the upward walls providing a round stick near the turning body on which two ends of band connected;
a regulator having opposite protruding buttons, wherein at both side of each protruding button provided with turning bodies while the turning bodies having a pair of tenons at its two transverse sides and chuck groves at the outsides thereof;
a pad underlying the casing seat;
two bands having ends mounting on the round sticks in the casing seat and the said ends provided with projection pieces;
a constriction configuration can be obtained when the state in which the ends tightly pulling the band achieved by the construct of said members; and that pressure on the protruding buttons makes support arms to move thereby the turning bodies are drawn movably around the tenons as axes by the support arms and then the turning bodies being in the state of lightly turning so that to make the chuck groves displace can form a disengagement operation of the chuck groves from the bands and further make the band loose.
The profile of the said casing seat presents arc shape.
The said pad is made of soft material.
The present invention assembly includes a casing seat that further has the function protecting the inside regulator from affecting by outside force or substance. The profile of the said casing seat may present flat smooth arc shape that not only reduces resistance but also gives its aesthetic feeling.
The present invention provides one pad between the assembly and head, wherein this pad may be made of more soft material and by which the pressure position on the head can be dispersed.
The regulator in the assembly can be made of material having deformable and flexible performance, such as POM, PVC, Silicone and Nylon.
The adjusting position of the present constriction assembly is apart from both sides of face mask. Therefore no large influence on the location of mask brought by the pull force exerted via the band and thus pressure on the face by the mask will be balanced.
The operation on the present assembly can be finished with single hand by two fingers' pressing on the button in the opposite direction and thus making the constriction assembly into loosen state, and exerting pull force on the two ends of the right and left bands can equably obtain the goal of constriction.
As shown in
The casing seat 10 is primarily used to mount regulator 20 as well as fasten bands 40, and the base of casing seat 10 is connected to the pad 30.
The casing seat 10 includes a casing body 11 that has a general long receptacle profile and the casing body 11 be provided with openings 12 at the right and left side thereof as well as upward walls 13 on the front and back thereof. The upward walls 13 are provided with two pairs of bores 14, 14′ and another group bores 15, 15′ at the corresponding positions thereof, respectively, as well as opposite bores 16 formed on the middle thereof. There is provided a connection seat 17 at the low of the casing body 11 that connected to the pad 30.
The regulator 20 includes a group opposite protruding buttons 21, support arms 22, 22′ at the both sides of each button 21 and turning bodies 23, 23′ provided at the two outsides of the support arms 22, 22′. A pair of general co-axes tenons 24, 24′ are formed on two sides of turning bodies 23, 23′ that are provided with chuck groves 25, 25′ at the peripheries thereof.
The said buttons 21 are received in the bores 16 while the tenons mounting in the bores 14, 14′ such that the regulator can be installed into the casing seat 10.
The pad 30 made of soft material is secured under the connection seat 17 for the intention of being mounted between the present assembly and the object to be constricted thereby making the present invention assembly be comfortably utilized.
To provide a pair of round sticks 41, 41′ on the two-pair bores 14, 14′ is to allow the band 40 passing through. The band 40 is well-known member and is made of soft material that can have considerable elasticity and pliability.
