Description

Binding device

Technical Field

The present invention relates to a restraint device, and more particularly to a restraint device that is removably attachable to an aquatic activity implement.

Background

For people who like to engage in various aquatic activities (such as diving, swimming and surfing), aquatic activity articles such as flippers, goggles or swimming goggles can be used, so that the aquatic activities can be favorably carried out by people. Such aquatic activity articles typically employ a securing strap to secure the aquatic activity article to the user. In an adjustable fin, there is no size limitation, so a fixing belt device is provided, and the user can fasten the fin on the sole of foot by wearing the fin on the ankle through the fixing belt device.

FIG. 1A is a schematic side view of a known fastening strap assembly 1 provided with an adjustable fin; fig. 1B is a schematic perspective view of the fixing strap device in a disassembled state at one end and in a combined state at the other end. As shown in fig. 1B, the fixing belt device 1 includes an elastic tube 11 and two fixing buckles 12. As shown in fig. 1A, the elastic tube 11 is elastically and stretchy put on the ankle K, and the fixing buckle 12 is made of plastic and detachably buckled on a mushroom headgear 10 on the side of the fin F.

Referring to fig. 1B, the two ends of the elastic tube 11 are respectively connected to the fixing buckles 12, wherein the elastic tube 11 and the fixing buckles 12 are connected to each other through the connecting member 13. The connecting member 13 and the fixing buckle 12 are generally made of plastic, and one end of the connecting member 13 has a male thread 14, and an inlet of one end of the fixing buckle 12 also has a corresponding female thread (not shown), so that a user can manually fasten the fixing buckle 12 to the connecting member 13 by himself.

As for the connection between the connecting member 13 and the elastic tube 11, the manufacturer needs to perform a special process to pre-form the two into a set of elastic tube assembly due to the different material properties of the two. However, this architecture allows users and manufacturers to face the following problems:

1. the elastic tube 11 is likely to be broken compared to the coupling member 13 because it needs to be stretched frequently. However, the user cannot disassemble the connecting member 13 by himself to replace the broken elastic tube 11, and only the whole set of elastic tube assembly can be discarded;

2. for the manufacturer, it is necessary to prepare elastic tubes 11 with different lengths to produce elastic band assemblies with different lengths, which greatly increases the production and inventory costs; and

3. since the user cannot adjust the length of the elastic tube 11 by himself, only the elastic tube assembly restricted by the manufacturer can be selected.

Accordingly, there is a need in the art for a fastening strap apparatus that can overcome the above-mentioned shortcomings.

Detailed Description

In the following embodiments and drawings, elements not directly related to the present invention have been omitted and not shown; and the dimensional relationships between the various elements in the drawings are merely for ease of understanding and are not intended to be limiting.

The utility model provides a detachably attaches to restraint device of aquatic activity apparatus, one of its characteristics is: "improve the user's freedom of use in replacing the elastic band and adjusting the length of the elastic band". In the following embodiments, the underwater activity device is exemplified by an adjustable flipper, and may be an underwater activity device that is applied to a flipper, a goggles, a swimming goggle, or the like, and requires an underwater article to be bound to a human body through an elastic band.

The binding device of the utility model comprises two belt buckles and an elastic belt. As shown in fig. 2, a buckle front end 311 of a buckle 3 is adapted to be inserted into a fastening device 5 of a flipper F, and a buckle rear end 312 of the buckle 3 is connected to the elastic band 4. After the buckle 3 is connected to the fin F, the user can put the elastic band 4 around the ankle K in a stretched state. The structural features of the restraint device 2 will be explained in detail below with reference to the accompanying drawings.

Referring to fig. 3A, one end of the restraint device 2 is in the disassembled state a, and the other end is in the assembled state B. As seen in the disassembled state a, each buckle 3 is composed of a body 32 and a cover 33, and the elastic band 4 has two ends 41 sandwiched between the body 32 and the cover 33, so as to exhibit a connection manner in which the ends 41 are fixed in the buckles 3 as shown in the assembled state B.

Fig. 3B is a partial enlarged view of the exploded state a continuing to fig. 3A, and fig. 3C is a partial enlarged view of the combined state B continuing to fig. 3A, in order to explain structural features and use manners of the body 32, the cover 33, and the elastic band 4.

Referring to fig. 3B, the main body 32 is divided into a receiving base 321 and a locking portion 322. The receiving base 321 is covered by the cover 33 to form the buckle 3, i.e. the two ends 41 are clamped between the receiving base 321 and the cover 33. The engaging portion 322 extends from the receiving base 321, and when the body 32 and the cover 33 form the buckle 3, the buckle front end 311 is the engaging portion 322 of the body 32.

The engaging portion 322 is a widely used quick release insert, and generally has a central claw member 322a and two symmetrical claw members 322b located at both sides of the central claw member 322a, and the central claw member 322a and the symmetrical claw members 322b are inserted into and fastened in the fastening device 5 (refer to fig. 2). Conversely, when the user presses the symmetrical claws 322b inward, the engaging portions 322 can be easily separated from the fastening device 5.

Regarding the receiving base 321, it has a bottom surface 321s therein and at least one positioning post 32P is formed, when the cover 33 covers the receiving base 321 to form the buckle 3, the positioning post 32P is located inside the buckle 3, i.e. the positioning post 32P is between the cover 33 and the receiving base 321. The positioning posts 32P function to fix the end 41 of the elastic band 4 so that the end 41 does not move forward and backward along the longitudinal direction of the elastic band 4. Specifically, each end portion 41 of the elastic band 4 has a plurality of positioning holes 411, and the positioning posts 32P are inserted into the positioning holes 411, so as to limit the front and rear movement of the end portion 41. In the present embodiment, the number of the positioning posts 32P is one, and a user can insert the positioning post 32P into one of the positioning holes 411 according to the length of the binding apparatus 2; of course, the number of the positioning columns can also be two, so that the two positioning columns can be matched with the two positioning holes. It should be noted that the shape of the positioning column of the present invention is not limited to the shape shown in the drawings, and may be a cylinder, an elliptical column, a rectangular column, a diamond column, or other various geometric shapes.

When the cover 33 covers the receiving base 321 to form the buckle 3, the buckle has an insertion opening 34 at the rear end 312. Specifically, the receiving base 321 has two first limiting protrusions 323 symmetrically disposed at a first distance, the first distance 323d is substantially smaller than an outer diameter 4R (see fig. 3B) of the elastic band 4, and a cover rear end 331 of the cover 33 has a guiding channel 332 (see fig. 5); when the buckle 3 is assembled, the guide passage 332 of the cover rear end 331 is disposed between the two first stopper projections 323 (see fig. 3C), so that the buckle rear end 312 is formed with an insertion port 34, and the insertion port 34 guides the elastic band 4 to extend out of the buckle 3. In short, the elastic band 4 inside the buckle 3 is extended out of the buckle 3 through the insertion opening 34 of the buckle rear end 312.

In more detail, referring to fig. 3B, a groove 32g is defined between two symmetrical first position-limiting protrusions 323, and when the buckle 3 is assembled, the groove 32g and the guiding channel 332 together form the insertion opening 34, wherein the surface of the insertion opening 34 conforms to the shape of the elastic band, for example, the elastic band is in a circular tube shape, and the surface of the insertion opening 34 is an arc-shaped curved surface. Furthermore, the first spacing 323d is substantially smaller than the outer diameter 4R of the elastic band 4, so that the aperture of the insertion opening 34 is also substantially smaller than the outer diameter of the elastic band 4; in this way, the elastic band 4 with elasticity can be pressed and clamped in the insertion opening 34. That is, the insertion port 34 is provided for preventing the elastic band 4 from coming off the insertion port 34.

Although the end portion 41 is restricted by the positioning post 32P so as not to be displaced forward and backward along the longitudinal direction of the elastic band 4, the elastic band 4 is repeatedly torn during underwater movement, and the end portion 41 in the buckle 3 may be shaken up and down or left and right, thereby separating the positioning post 32P from the positioning hole 411. Therefore, in order to enhance the connection strength between the buckle 3 and the elastic band 4, two protection devices are provided on the inner surfaces of the body 32 and the cover 33.

Referring to fig. 3A and 5, in the protection device for preventing the left and right shaking, two second limit protrusions 324 are disposed in the accommodating base 321 of the body 32, and two first protrusions 333 are disposed on an inner surface 33A of the cover 33. Specifically, the two second limiting protrusions 324 are symmetrically formed on the bottom surface 321s of the accommodating base 321 with a second distance 324d, and the positioning pillar 32P is disposed between the two second limiting protrusions 324, wherein the second distance 324d is substantially smaller than the outer diameter 4R of the elastic band 4. As a result, when the positioning hole 411 is inserted into the positioning post 32P, the end 41 near the inserted positioning hole 411 is pressed and clamped between the two second limiting protrusions 324 (refer to fig. 4), and cannot be easily shifted left and right. Referring to fig. 5, the second bumps 333 are also symmetrically formed on an inner surface 33a of the cover 33 at a distance; the first protrusions 333 are located near the guiding channel 332 at the rear end 331 of the cover, so that when the cover 33 covers the receiving base 321, the end 41 near the guiding channel 332 is pressed between the two first protrusions 333 at the upper surface thereof. In other words, the second limit protrusion 324 and the second protrusion 333 prevent the end 41 of the section from the positioning post 32P to the insertion opening 34 in the buckle 3 from swaying left and right.

With respect to the protection device for preventing the vertical movement, referring to fig. 5, the inner surface 33a of the lid 33 further has a second protrusion 334 located relatively far away from the rear end 331 of the lid. In more detail, referring to the elastic band and the buckle of fig. 7, the second bump 334 is located between the positioning post 32P and the front end 311 of the buckle. In this way, when the cover 33 covers the accommodating base 321, the second bump 334 directly presses against the upper surface of the end portion 41 of the elastic band 4, so that there is no space between the end portion 41 and the first bump 333 that may shake up and down.

The fixed connection between the cover 33 and the receiving base 321 is performed by the engaging groove of the receiving base 321 and the engaging tenon of the cover 33. Specifically, referring to fig. 3B and fig. 5, each first limiting protrusion 323 has a surface 323s facing the positioning post 32P, the surface 323s forms a first groove 325, and the cover 33 forms two first tenons 335 corresponding to the first grooves 325, so that the two first tenons 335 are respectively engaged in the two first grooves 325. The first groove 325 and the first tongue 335 are located generally at the buckle rear end 312 and belong to a first set of engagement points.

To ensure complete engagement of the buckle, a second set of engagement points is added. Referring to fig. 3B, a second groove 326 is formed at the center of an interface 32s between the receiving base 321 and the engaging portion 322, and the cover 33 has a second engaging tongue 336, and the second engaging tongue 336 is engaged in the second groove 326. In short, the first set of joints and the second set of joints constitute a stable joint state in which three points are coplanar.

For the structure of the elastic band 4, please refer to fig. 7, fig. 8A-fig. 8H. The elastic band 4 can be selectively a hollow tube as shown in fig. 8A-8D or a solid tube as shown in fig. 8E-8H, and the diameter r thereof is preferably between 7-8 millimeters (mm), wherein the positioning holes 411 are equidistantly disposed along the length direction L of the elastic band 4. In the present embodiment, the positioning holes 411 are disposed equidistantly, and the exceptional positioning holes can also be disposed non-equidistantly, for example, the arrangement distance is set by an equal ratio or an equal difference number sequence. In addition, the depth of the positioning hole 411 can selectively penetrate through the elastic band 4 in fig. 8B or 8F or not penetrate through the elastic band 4 itself in fig. 8D or 8H along a hole axis Φ direction of the positioning hole 411.

In the present invention, the elastic band 4 can be made of natural latex, rubber, thermoplastic rubber (TPR), silica gel, Ethylene Vinyl Acetate copolymer (EVA) and other materials, and such materials can make the elastic band generate high tensile elasticity, flexibility and recoverable elastic deformation. As shown in fig. 7 and 8A-8H, when the positioning pin 32P is inserted into the middle positioning hole 411, the middle positioning hole is expanded, which causes the hole diameters of other positioning holes to be relatively reduced, and once the positioning pin is removed, all the positioning holes are restored to the original hole diameters. Alternatively, as the elastic band 4 is clamped between the first stopper projections 323 or the second stopper projections 324, the outer diameter of the elastic band 4 in this section is compressed and reduced (see fig. 4), and then returns to its original shape once removed (see fig. 3B).

In addition, the manufacturer can provide the user with a longer length of the elastic band 41, and the user can shorten the length of the elastic band as desired by cutting out the unnecessary end portion near the positioning hole by himself. For example, as shown in fig. 6 of the present embodiment, the end portion 41 originally has 3 positioning holes 411, and the last section of the end portion 41 is cut away, leaving only two positioning holes 411. The utility model discloses in, the quantity of locating hole does not use the drawing as the limit, can be more locating holes, so elastic webbing length just can have bigger adjustment range.

With the above structure, when the binding device 2 of the present invention is in the disassembled state a, the binding device is substantially restored to the assembled state B through the following steps:

the first step is as follows: the user takes up the body 32 and the elastic band 4, aligns and inserts a positioning post 32P with a positioning hole 411 (see fig. 3B), and the end 41 near the inserted positioning hole 411 is also engaged and clamped between the two second limiting protrusions 324 (see fig. 4), so that the end 41 will not move forward and backward along the length direction L of the elastic band 4, nor move in a direction perpendicular to the length direction L (i.e. sway left and right).

The second step is that: the section of the end 41 near the two first stopper projections 323 is fitted in the two first grooves 32g, that is, the end 41 is pressed between the two first stopper projections 323. At this time, the end 41 of this section is clamped so as not to move forward and backward in the longitudinal direction L and not to shake left and right.

The third step: the two first tenons 335 of the cover 33 are first respectively engaged with the two first grooves 325 of the accommodating base 321, and then the second tenons 336 of the cover 33 are engaged with the second grooves 326 of the accommodating base 321, so that the cover 3 and the accommodating base 321 are tightly engaged and fixed (see fig. 3C). At this time, the binding apparatus 2 of the present invention is assembled, the end 41 of the elastic band 4 is fixed to the inside of the buckle 3, the elastic band 4 other than the end is extended out of the buckle 3 through the insertion port 34 of the buckle rear end 312, and the elastic band 4 is clamped by the insertion port 34.

Therefore, the buckle 3 and the elastic band 4 used in the binding device 2 of the present invention not only have a firm connection effect, but also have the following advantages:

1. the combination and disassembly of the buckle 3 and the elastic band 4 can be easily accomplished by the user himself with bare hands.

2. No matter the belt buckle 3 or the elastic belt 4 is damaged, the user only needs to replace the damaged part without discarding the whole group of the binding device 2; and

3. the effect of the location holes of the elastic band 4 is: for the manufacturer, only one length of elastic belt needs to be produced, and the forming of the positioning holes does not need complex processes, which is beneficial to reducing the production and inventory cost. On the other hand, the flexible material of the elastic band can be used to cut the overlong elastic band section directly with scissors or a knife, so the length of the elastic band provides a user with higher freedom of adjustment.

The above-mentioned embodiments are only used to exemplify the implementation of the present invention and illustrate the technical features of the present invention, and are not used to limit the protection scope of the present invention. Any modifications or equivalent arrangements which may be readily devised by those skilled in the art are intended to be included within the scope of the present invention as defined by the appended claims.
