Description:

BACKGROUND THE INVENTION

[0001] This invention relates to a fastening belt capable of disassembling, particularly to a novel fastening belt which can be cut into any desired length, and which can be disassembled and used again.

[0002] A conventional fastening belt consisting of a belt body and a fastening head has a fixed length in belt body corresponding to each specified size, and one end of the belt body is integral with the fastening head. In addition, in order to fasten a bigger object, the fastening belt usually has excess allowance length, which results in material waste. Furthermore, since there is an irreversible fixing engagement structure between the fastening head and the belt body, the belt body will be destroyed when disassembled.

[0003] A Taiwanese Patent Publication No. 287610 discloses a “Multifunctional fastening belt”, in which said belt essentially consists of a primary belt body and secondary belt body, the leading end of primary belt body having a clip tab and hole. The back of said clip tab is abutting with a fixed piece and has a tangentially provided fixed strip. The front segment of the fixed piece has a hole for buckling. The secondary belt body is connected with the end of the primary belt body. The above-mentioned fastening belt can achieve the goal of tie-up and fixing by the engagement of primary and secondary belt body integrally molded together. However, said primary and secondary belt body have fixed length respectively. Therefore, it is still has the problem of over length waste or insufficient length plight.

[0004] In addition, a Taiwanese Patent Publication No. 359259 discloses a “Capable of disassembling joint type positioning fastening belt”, in which there is essentially a conical inserting blocks provided in the opposite outer side edges at both ends of a flat fastening belt. The inserting block can easily pass through the positioning hole itself, and both ends of the inserting block can join together against the edge of hole after passing through the positioning hole. During disassembling, the inserting block is drawn out from the positioning hole in order with a staggered way. In this way, the fastening belt can be re-used after disassembling. Although the above-mentioned fastening belt can achieve the goal of re-use after the draw-out of inserting block from the positioning hole in order with a staggered way, said fastening has fixed length and is possibly to stagger the inserting block when the fastening belt has enough allowance. The fastening belt thus formed can not fasten object to be fastened. Instead, it can only circle around object to be fastened very loosely within the length range of the fastening belt.

SUMMARY OF THE INVENTION

[0005] The primary object of this invention is to provide a fastening belt capable of disassembling, wherein the fastening belt can be produced by a consecutive process and is cut into proper length after fastening operation on object to be fastened so as not to cause material waste.

[0006] Another object of this invention is to provide a fastening belt capable of disassembling which can be re-used after disassembling so as to match environmental protection concept and save cost.

[0007] The above and other objects can be attained by the fastening belt of present invention, in which the fastening belt comprises a belt with selective length having a plurality of parallelly disposed teeth recesses provided on its top surface, a fastening socket with an inlet port on one end and with another inlet port and outlet port on the other end, in which an upper-side ratchet piece and a lower-side ratchet piece, facing oppositely each other, are extended from opposite side walls respectively, a plurality of ratchet teeth being provided on each ratchet piece respectively. Firstly, the fixed end of fastening belt is inserted into the fastening socket from one end and clipped on the lower-side ratchet piece, and then the free end of the same passes through the fastening socket from the other end and clips with the upper-side ratchet piece. Then the fastening belt thus fastened is duly cut into proper length so as not to cause material waste.

[0008] According to present invention, a recess of each ratchet piece is formed at the base portion so as to provide each ratchet piece with resiliency. The ratchet teeth will disengage from the teeth recesses after the ratchet piece is moved upwardly. Thus, the fastening belt can be disassembled for repeat use. Accordingly, this will result in cost saving and reduce environmental problems.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT OF THE PRESENT INVENTION

[0023] Firstly, referring to FIGS. 1, 2 and 3, a fastening belt capable of disassembling 1 of this invention comprises a fastening socket 10 and a belt 20 with selective length. An inlet port 110 is provided on one end of side wall of the fastening socket 10. A ratchet piece 11 is extended inwardly from the upper end of the same side wall. An inlet port 120 and an outlet port 121 are provided on the other end of side wall, and a ratchet piece 12 is extended inwardly from the same side wall. These two ratchet pieces 11,12 are formed oppositely in an up-down relationship with each other. A plurality of ratchet teeth 111, 122 are formed parallelly at equal distance on the bottom faces of two ratchet pieces 11,12 respectively. Guiding inclined surface 111a, 122a corresponding to the orientation of inlet port 110, 120 are formed respectively on the outside faces, and abutting face 111b, 122b relative to the inside of ratchet teeth 111, 122 are formed respectively on the inside faces of these two ratchet pieces 11,12. An included angle β is formed between said abutting face 111b, 122b and a line perpendicular to the fastening socket 10, with the value of β being between 5° and 25°, preferably 15°, so as to form an acute angle edge.

[0024] According to present invention, guiding inclined surfaces 110a, 120a are formed on the lower-edge walls of inlet port 110, 120 respectively, so as to facilitate the passing through of belt 20. The guiding inclined surface 110a on the lower ratchet piece 12 corresponding to inlet port 110 has an included angle α with the horizontal line of fastening socket 10, with the value of α being within 50°˜20°, preferably being 100. The ratchet teeth 111 of upper-side ratchet piece 11 is formed corresponding to the included angle α. A guiding plate 13 with the same inclination angle as α is extended below the upper-side ratchet piece 11, i.e. at the inside the guiding inclined surface 110a of inlet port 110. Narrow teeth recesses 112, 124 are provided on the respective base portion of ratchet piece 11, 12, with a purpose to provide the ratchet piece 11, 12 with resilient feature. Additionally, a top plate 123 is provided at the upper end of fastening socket 10, and an outlet port 121 is formed at the opposite end corresponding to the inlet port 110.

[0025] Referring to FIG. 4 and FIG. 5, the belt 20 of this invention can have any selective length, and have a plurality of parallelly disposed teeth recesses 21 provided on its top end surface at equal distance, the distance between two adjacent teeth recesses 21 corresponds to the distance between two adjacent ratchet teeth 11, 122 of the ratchet pieces 11, 12 respectively. Two sides of a tooth portion 22 formed between two teeth recesses 21 have an included angle θ with its value 1°<θ<90°, preferably between 1° and 20°, such that better engagement of teeth recesses with ratchet teeth 111, 122 can be obtained.

[0026] Referring to FIG. 6, the fixed end of belt 20 is firstly inserted into the inlet port 120 of fastening socket 10 from one end and the ratchet teeth 122 of the lower-side ratchet piece 12 engages with the teeth recesses 21 on the belt 20, and then the free end of the same passes through the other end of the fastening socket 10 into the inlet port 110 and the ratchet teeth 111 of the upper-side ratchet piece 11 engages with the teeth recesses 21 on the belt 20, when in use. Because the guiding inclined surface 11a, 122a, and abutting face 111b, 122b with acute angle are formed respectively on the outside faces and the inside faces of the ratchet teeth 111,122, the belt 20 can goes through very easily and a resist force in reverse direction can be formed against abutting faces. Then the fastening belt thus fastened on object to be fastened is duly cut into proper length so as not to cause material waste. The ratchet teeth 111, 122 will disengage from the teeth recesses 21 after the free end of the ratchet piece 11,12 are moved upwardly when disassembling. Thus, the fastening socket 10 can be separated from the belt 20 for repeat use. Accordingly, this will result in cost saving and reduce environmental problems.

[0027] FIG. 7 and FIG. 8 show the second embodiment of present invention, the structure of which is approximately the same as aforementioned embodiment. The fastening belt in the second embodiment comprises an included angle α formed between the upper end-surface of the lower ratchet piece 12 and the horizontal line of fastening socket 10, and included angle between a line connected along the tip end of ratchet teeth 111 of the upper-side ratchet piece 11 and the horizontal line is the same as α. The difference with the former embodiment is: the fastening socket 10 comprises two ratchet pieces 11,12 oppositely oriented and overlapped in vertical direction. A plurality of ratchet teeth 111, 122 with saw tooth-shaped are formed respectively on the bottom of the two ratchet pieces 11,12. Guiding inclined surface 111a, 122a are formed respectively on the outside faces of the ratchet teeth 111,122, and abutting face 111b, 122b with right angle are formed respectively on the inside faces of the ratchet teeth 111,122.

[0028] FIG. 9 and FIG. 10 show the third embodiment of present invention, the structure of which is approximately the same as the second embodiment. Therefore, description for the same structure is omitted here. The difference is: The ratchet teeth 111,122 are formed in single number respectively on the bottom of the two ratchet pieces 11,12. An included angle α is formed between the bottom end surface of the ratchet teeth 122 of the ratchet piece 12 and the horizontal line of fastening socket 10, with the value of α being between 5° and 20°, preferably being 10°, such that a guiding inclined surface 122a can be formed in the inserting direction. The included angle between the upper end face of the lower-side ratchet piece 12 and the bottom end face of the ratchet teeth 111 of the upper-side ratchet piece 11 corresponds to this angle α. An included angle β is formed between the inside face of the ratchet teeth 111,122 and a line perpendicular to the fastening socket 10, with the value of β being between 5° and 25°, preferably 15°, so as to form an acute abutting face 111b, 122b in the clip direction. Thus, better engagement of the ratchet teeth 111,122 with teeth recesses 21 of the belt 20 can be obtained.

[0029] FIGS. 11 12 and 13 show the fourth embodiment of present invention. Responding to the demand of miniaturization of the volume of the fastening socket 10, a double-layer structure formed by the combination of two metal parts 10a, 10b with its cross section in rectangular shape (shown in FIG. 11) is used in this embodiment, in which an inlet port 120, 110 and an outlet port 121, 113 are formed respectively on both ends of said fastening socket 10. Two opposite ratchet pieces 11, 12 with slanted side are formed respectively from the top walls of the upper-layer metal part 10a and lower-layer metal part 10b by punching operation. The fixed end of belt 20 is firstly inserted into the inlet port 120 on one end of the fastening socket 10 and the bottom end of the lower-layer ratchet piece 12 clips with the teeth recesses 21 on the belt 20, then the free end of the same passes through the other end of the fastening socket 10 and inserts into the inlet port 110, and the bottom end of upper-layer ratchet piece 11 engages with the teeth recesses 21 on the belt 20. Then the fastening belt thus fastened on object to be fastened is duly cut into proper length.

[0030] Especially, the inventor of present invention would like to emphasize herein, in that the belt of this invention can be produced consecutively with extrusion molding method and can be duly cut to certain length according to the demand of user by the utilization of present invention. Therefore, the production cost can be greatly reduced and the convenience of use can be increased.

[0031] The aforementioned so far is merely preferred embodiments of present invention, they should not be considered as limitation on the range of application of present invention. Any equivalent variations and modifications without departing from the spirit of claims of present invention are considered within the range of present invention.
