BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a fastening device, and in particular, relates to a fastening device that can be attached to an activity equipment, such as a water activity equipment.

Descriptions of the Related Art

For people who like to do various kinds of activities (such as diving, swimming and surfing), activity products and/or water activity products such as flippers, diving goggles, or swimming goggles are used to facilitate those activities. Such water activity products usually use fixing bands to tie them onto users. For example, with adjustable flippers, the flipper is designed to meet the different sizes of the users' ankles. The fixing band device will be provided and the user fasten the flippers on the sole by wearing the fixing band device on the ankle.

FIG. 1A is a schematic side view of a conventional fixing band device 1 provided on an adjustable flipper. FIG. 1B is a schematic perspective view of the fixing band device with one end thereof in an exploded state and the other end thereof in an assembled state. As shown in FIG. 1B, the fixing band device 1 includes a flexible tube 11 and two fixing buckles 12. As shown in FIG. 1A, the flexible tube 11 is elastic and thus, is stretchably sleeved on the ankle K. The fixing buckle 12 is made of plastic and detachably buckled on a mushroom-head kit 10 on the side surface of a flipper F.

With reference to FIG. 1B, the two ends of the flexible tube 11 are respectively connected with the fixing buckles 12, wherein the flexible tube 11 and the fixing buckles 12 need to be connected with each other through a connecting piece 13. The connecting piece 13 is also made of plastic like the fixing buckles 12. One end of the connecting piece 13 is provided with external threads 14, and the inlet of one end of the fixing buckle 12 is also provided with corresponding internal threads (not shown) so that a user may manually bolt the fixing buckle 12 on the connecting piece 13.

As for the connection of the connecting piece 13 and the flexible tube 11, it is necessary for manufacturers to prefabricate them into a set of flexible tube assemblies through a special fabrication process because of different properties of materials of the connecting piece 13 and the flexible tube 11. However, such architecture makes users and manufacturers face the following problems:

1. The flexible tube 11 needs to be stretched frequently. As a result, the tube is more easily damaged than the connecting piece 13. However, the user cannot disassemble by himself/herself the connecting piece 13 to replace the damaged flexible tube 11, so the user can only discard the whole set of flexible tube assemblies.

2. For manufacturers, it is necessary to prepare flexible tubes 11 of different lengths to produce flexible band assemblies of different lengths, thus, greatly increasing the production and inventory costs.

3. Since the user cannot adjust the length of the flexible tube 11 by himself/herself, the user can only choose to buy the flexible tube assemblies limited by the manufacturers.

Accordingly, it is important to provide a fixing band device capable of improving the above-mentioned defects.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a fastening device which is configured to be attached to an activity equipment, and in particular, the fastening device according to the present invention is also adapted to be detachably attached to an activity equipment, such as a water activity equipment.

To achieve the objective of the aforesaid fastening device, the buckle has a front end which is adapted to be attached to a buckling device of the activity equipment. The front end of the buckle forms a buckling portion extending from the accommodating base.

To achieve the objective of the aforesaid fastening device, each of the first limiting bumps has a surface facing the at least one positioning pillar. The surface is formed with a first mortise. The cover has two first tenons which are correspondingly buckled together with the first mortises respectively.

To achieve the objective of the aforesaid fastening device, a second mortise is centrally formed at an interface between the accommodating base and the buckling portion. The cover has a second tenon which is correspondingly buckled with the second mortise.

To achieve the objective of the aforesaid fastening device, the flexible band is optionally a solid tube or a hollow tube, wherein the flexible band is provided with a plurality of positioning holes which are equidistantly arranged along the axial direction of the flexible band. Therefore, the user adjusts the length of the flexible band as needed by cutting off sections of the flexible band on which the positioning holes are unnecessary. In addition, forming positioning holes on the flexible band features a simple process and can also effectively reduce the manufacturing cost.

To achieve the objective of the aforesaid fastening device, the plurality of positioning holes optionally penetrate through or not penetrate through the flexible band in a radial direction of the flexible band, in particular, the positioning holes are at least partially formed all way through the flexible band.

 DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following embodiments and drawings, elements not directly related to the present invention have been omitted from depiction. Moreover, dimensional relationships among individual elements in the drawings are only for ease of understanding and are not used to limit the actual proportions.

The present invention provides a fastening device which is configured to be attached to an activity equipment, and in particular, the fastening device according to the present invention is also adapted to be detachably attached to an activity equipment, such as a water activity equipment. One of the characteristics of the fastening device is to “improve the degree of freedom for a user in replacing a flexible band with a new one, and adjusting the length of the flexible band”. In the following embodiment, an adjustable flipper is taken as an example of the activity equipment. In addition to being used on flippers, the fastening device can also be used on other activity equipment, in particular the water activity equipment, such as diving goggles or swimming goggles or the like which requires a flexible band to be fastened on a human body.

The fastening device preferably disclosed in the present invention comprises two opposing portions, at least one of which is detachable from the activity equipment and includes a buckle and a flexible band. That is, the fastening device may comprise a buckle connected to the one end portion of the flexible band that can be detachably attached to the activity equipment, and another end portion of the flexible band with or without the buckle is configured to fix on or extend from the activity equipment e.g., be integrated with, or inherently attached from the activity equipment in a manner as being used in existing art that is easily comprehended (not shown). Alternatively, the fastening device may comprise two buckles connected to the each end portion of the flexible band respectively so the whole fastening device is detachably attached to the activity equipment. As for the fastening device 2 shown in FIG. 2, a front end 311 of a buckle 3 is adapted to be inserted into the buckling device 5 of a flipper F. A rear end 312 of the buckle 3 is connected to the flexible band 4. After the buckle 3 is connected with the flipper F, the user may stretch the flexible band 4 to fit on the ankle K. Structural features of the fastening device 2 will be described in detail below through the drawings.

With reference to FIG. 3, in an embodiment with two buckles, one end of the fastening device 2 is in an exploded state A, while the other end thereof is in an assembled state B. As seen in the exploded state A, each buckle 3 itself comprises a body 32 and a cover 33. Two end portions 41 of the flexible band 4 are clamped between the body 32 and the cover 33 to present a connection mode in which the end portion 41 is fixed in the buckle 3 as shown in the assembled state B.

FIG. 3A is a partially enlarged view of the exploded state A as the continuation of FIG. 3, while FIG. 3B is a partially enlarged view of the assembled state B as the continuation of FIG. 3 to facilitate the description of the structural features and usage of the body 32, the cover 33, and the flexible band 4.

With reference to FIG. 3A, the body 32 is divided into an accommodating base 321 and a buckling portion 322. The accommodating base 321 is covered by the cover 33 to form the buckle 3. That is, the two end portions 41 are clamped between the accommodating base 321 and the cover 33. The buckling portion 322 extends from the accommodating base 321, and when the body 32 and the cover 33 form the buckle 3, the front end 311 of the buckle 3 forms a buckling portion 322.

The buckling portion 322 is a commonly used quick-release insert which usually has a central claw 322a and two symmetrical claws 322b located on both sides of the central claw 322a. The central claw 322a and the symmetrical claws 322b are inserted together and locked in the buckling device 5 (see FIG. 2). On the contrary, when the user presses the two symmetrical claws 322b inward, the buckling portion 322 can be easily separated from the buckling device 5.

The accommodating base 321 has a bottom surface 321s and at least one positioning pillar 32P is formed therein. When the cover 33 is covered on the accommodating base 321 to form the buckle 3, the positioning pillar 32P is located inside the buckle 3. That is, the positioning pillar 32P is located between the cover 33 and the accommodating base 321. The positioning pillar 32P serves to fix the end portion 41 of the flexible band 4 so that the end portion 41 does not move forward or backward in the length direction (or axial direction) of the flexible band 4. Specifically, each (or one) of the end portions 41 of the flexible band 4 has at least one positioning hole 411 into which the positioning pillars 32P are inserted respectively, thereby, restricting the forward and backward movement of the end portion 41. In this embodiment, the number of the positioning pillar 32P is one, and the user may insert one positioning pillar 32P into the one or one of the positioning holes 411 according to the required length of the fastening device 2. Of course, the number of the positioning pillars may also be two, so the two positioning pillars will be matched with two positioning holes. It shall be additionally appreciated that the shape of the positioning pillars is not limited to what is shown in the drawings. There may also be pillars of various geometrical shapes such as cylindrical, oval, rectangular, and diamond shapes.

When the cover 33 is covered on the accommodating base 321 to form the buckle 3, there is an insertion opening 34 at the rear end 312. Specifically, the accommodating base 321 has two first limiting bumps 323 which are symmetrical and apart from each other by a first spacing. The first spacing 323d is substantially smaller than the outer diameter 4R of the flexible band 4 (see FIG. 3A). The rear end 331 of the cover 33 has a guide channel 332 (see FIG. 5). When the buckle 3 is formed, the guide channel 332 of the rear end 331 is disposed between the two symmetrical first limiting bumps 323 (see FIG. 3B), so the rear end 312 is formed with an insertion opening 34 for guiding the flexible band 4 to extend outward from the buckle 3. Briefly speaking, the flexible band 4 inside the buckle 3 extends out of the buckle 3 through the insertion opening 34 at the rear end 312.

In more detail, with reference to FIG. 3A, a groove 32g may be defined between the two symmetrical first limiting bumps 323. When the buckle 3 is formed, the groove 32g and the guide channel 332 together form the insertion opening 34, wherein the surface of the insertion opening 34 conforms to the shape of the flexible band. For example, if the flexible band is a circular tube, then the surface of the insertion opening 34 will be an arc-shaped surface. Furthermore, the first spacing 323d is substantially smaller than the outer diameter 4R of the flexible band 4 so that the diameter of the insertion opening 34 is also substantially smaller than the outer diameter of the flexible band 4. In this way, the flexible band 4 with elasticity can be squeezed and clamped in the insertion opening 34. In other words, the insertion opening 34 further has the function of preventing the flexible band 4 from falling off from the insertion opening 34.

Although the end portion 41 has been restrained by the positioning pillar 32P not to move forward and backward along the length direction of the flexible band 4. The flexible band 4 is repeatedly pulled during the water activity, and the end portion 41 in the buckle 3 may still shake up and down or left and right, thereby, causing the separation of the positioning pillar 32P from the positioning hole 411 into which it is inserted. Therefore, to improve the connection strength between the buckle 3 and the flexible band 4, two additional protective mechanisms are further arranged inside the body 32 and the cover 33.

With reference to FIG. 3A and FIG. 5 for the protection mechanism for preventing left and right shaking, two second limiting bumps 324 are provided in the accommodating base 321 of the body 32. Two first protrusions 333 are provided on the inner surface 33a in the cover 33. Specifically, the two second limiting bumps 324 are symmetrical and formed on the bottom surface 321s of the accommodating base 321 with a second spacing 324d therebetween. The positioning pillar 32P is located between the two second limiting bumps 324, wherein the second spacing 324d is substantially smaller than the outer diameter 4R of the flexible band 4. In this way, when the positioning hole 411 is inserted by the positioning pillar 32P, the end portion 41 near the inserted positioning hole 411 will be squeezed and clamped between the two second limiting bumps 324 (see FIG. 4) and will not easily shift left and right. With reference to FIG. 5, the two first protrusions 333 are also symmetrically formed on the inner surface 33a of the cover 33 with a distance therebetween. The first protrusion 333 is located close to the guide channel 332 of the rear end 331, and thus, when the cover 33 is covered on the accommodating base 321, the end portion 41 close to the guide channel 332 is also pressed between the two first protrusions 333 at its upper surface. Furthermore, the end portion 41 in the section from the positioning pillar 32P to the insertion opening 34 in the buckle 3 does not shake left and right through the arrangement of the second limiting bump 324 and the two first protrusions 333.

With reference to FIG. 5, the protection mechanism for preventing upward and downward shaking, the inner surface 33a of the cover 33 is further provided. The second protrusion 334 which is located relatively far away from the rear end 331. In more detail, with reference to the partial cross-sectional view of the flexible band and the buckle thereof in FIG. 7, the second protrusion 334 is located between the positioning pillar 32P and the front end 311. In this way, when the cover 33 is covered on the accommodating base 321, the second protrusion 334 directly presses against the upper surface of the end portion 41 of the flexible band 4 so that there is no potential space to shake up and down between the end portion 41 and the first protrusion 333.

The fixed engagement of the cover 33 and the accommodating base 321 is performed through the mortise of the accommodating base 321 and the tenon of the cover 33. Specifically, with reference to FIGS. 3A and 5, each first limiting bump 323 has a surface 323s facing the positioning pillar 32P. The surface 323s is formed with a first mortise 325. The cover 33 is formed with two first tenons 335 corresponding to the first mortise 325, so the two first tenons 335 are respectively engaged in the two first mortises 325. The first mortise 325 and the first tenon 335 are generally located at the rear end 312 and belong to the first set of junctions.

To ensure complete engagement of the buckle, a second set of junction is added. With reference to FIG. 3A, a second mortise 326 is centrally formed at an interface 32s between the accommodating base 321 and the buckling portion 322. The cover 33 correspondingly has a second tenon 336 so that the second tenon 336 can be buckled in the second mortise 326. Briefly, the first junction and the second set of junction form a three-point coplanar and stable joint state.

FIG. 7 illustrates the structure of the flexible band 4. The flexible band 4 may optionally be hollow tubes (a) to (b) or solid tubes (c) to (d), and the diameter r thereof is preferably between 7 and 8 millimeters (mm), wherein the positioning holes 411 are equidistantly arranged along the axial direction L of the flexible band 4. In this embodiment, the plurality of positioning holes 411 are equidistantly arranged. As an exception, the positioning holes may also be non-equidistantly arranged, e.g., the arrangement distance may be set in an equal ratio or arithmetic progression. In addition, the depth of the positioning hole 411 may optionally penetrate through (a), (c) or not penetrate through (b), (d) the flexible band 4 itself along an axial direction Φ of the positioning hole 411, in particular, the plurality of positioning holes 411 are at least partially formed all way through the flexible band 4 in a radial direction of the flexible band 4.

In the present invention, the flexible band 4 may optionally be made of natural latex, rubber, thermoplastic rubber (TPR), silica gel, ethylene vinyl acetate (EVA) or other materials. These materials can enable the flexible band to produce high tensile elasticity, flexibility and restorable elastic deformation. As shown in FIG. 7, when the positioning pillar 32P is inserted into the middle positioning hole 411, the middle positioning hole will be enlarged, which causes apertures of other positioning holes to become relatively small. Once the positioning pillar is removed, all positioning holes will restore to the original aperture size. Alternatively, if the flexible band 4 is clamped between the two first limiting bumps 323 or between the second limiting bumps 324, then the outer diameter of the flexible band 4 in this section is compressed and reduced (as shown in FIG. 4). The flexible band can be restored to its original appearance (as shown in FIG. 3A) once it is removed.

In addition, the manufacturer may provide a longer flexible band 41 to the user, and the user can shorten the length of the flexible band according to requirements only by cutting off unnecessary sections of the end portion near the positioning holes. For example, as shown in FIG. 6 of this embodiment, the end portion 41 originally has three positioning holes 411. The last section of the end portion 41 is cut off to leave only two positioning holes 411. In the present invention, the number of the positioning holes is not limited to the drawings, and more positioning holes can be provided so that the length of the flexible band can be adjusted within a larger range.

With the above structure, the fastening device 2 of the present invention is restored to the assembled state B by the following steps when it is in the exploded state A:

Step 1: The user picks up the body 32 and the flexible band 4, aligns one positioning pillar 32P with one positioning hole 411 and engages them together (as shown in FIG. 3A). At this time, the end portion 41 near the inserted positioning hole 411 will also be fitted and clamped between the two second limiting bumps 324 (as shown in FIG. 4) so that the end portion 41 will not move forward or backward along the axial direction L of the flexible band 4, nor will it move in a direction perpendicular to the axial direction L (which means shaking left and right).

Step 2: The section of the end portion 41 near the two first limiting bumps 323 is fitted into the two first grooves 32g. That is, the end portion 41 is squeezed between the two first limiting bumps 323. At this time, this section of the end portion 41 is clamped so as not to move forwards and backwards in the axial (longitudinal) direction L, nor to shake left and right.

Step 3: First, the two first tenons 335 of the cover 33 are respectively engaged in the two first mortises 325 of the accommodating base 321, and then the second tenon 336 of the cover 33 is engaged in the second mortise 326 of the accommodating base 321 so that the cover 3 and the accommodating base 321 are tightly engaged and fixed (as shown in FIG. 3B). At this time, the assembly of the fastening device 2 of the present invention has been completed. The end portion 41 of the flexible band 4 is entirely fixed inside the buckle 3. The flexible band 4 beyond the end portion extends outside the buckle 3 through the insertion opening 34 at the rear end 312, and the insertion opening 34 also clamps the flexible band 4.

As can be known from the above descriptions, the buckle 3 and the flexible band 4 used in the fastening device 2 of the present invention not only have a firm connection effect, but also have the following advantages:

1. The assembly and disassembly of the buckle 3 and the flexible band 4 can be easily completed by the users themselves with bare hands.

2. If either the buckle 3 or the flexible band 4 is damaged, the user only needs to replace the damaged parts without the need of discarding the whole set of fastening devices 2; and

3. The effect of the positioning hole of the flexible band 4 is as follows: only one length of flexible bands need to be produced for the manufacturers. The forming of the positioning hole does not need a complicated manufacturing processes, which is helpful to reduce the production and inventory costs. On the other hand, because the material of the flexible band is soft, the redundant flexible band section can be directly cut off by scissors or cutters, so the user is provided with a higher degree of freedom in the adjustment of the length of the flexible band.

The above disclosure is related to the detailed technical contents and inventive features thereof. People skilled in this field may proceed with a variety of modifications and replacements based on the disclosures and suggestions of the invention as described without departing from the characteristics thereof. Nevertheless, although such modifications and replacements are not fully disclosed in the above descriptions, they have substantially been covered in the following claims as appended.
