Guiding Type Anti-Falling Harness Unit

Abstract

A guiding type anti-falling harness unit includes a safety wear comprising a strap unit on the back thereof for a support member and a lifting ring to mount. The support member has a first slot and a second slot for the strap unit to pass through so as to define a securing region between the strap unit and the outer side of the support member. A bushing is arranged in the securing region and has a channel provided transversely across the securing region. The bushing has a slideway to allow the bushing to correspondingly move up and down along the strap unit within the securing region and without escaping from the left or right side of the securing region easily. The channel is adaptable for a latch of a connecting device to couple with. Accordingly, the harness unit allows the user to quickly latch the latch at the securing region directly without pulling the strap unit, which greatly enhances the adaption in mounting and dismounting of the connecting device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0028] The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

[0029] Referring to FIGS. 2-7, an anti-falling harness unit according to a preferred embodiment of the present invention is illustrated, wherein the harness unit comprises a safety wear 10, a support member 20, a lifting ring 30, a bushing 40, and a connecting device 50 adapted for coupling with the bushing 40.

[0030] The safety wear 10 is adapted for being worn by a personnel, wherein the safety wear 10 comprises a strap unit 11 on the back thereof. The safety wear 10 comprises a first strap 12 and a second strap 13 arranged with the first strap 12 in a cross manner.

[0031] The support member 20 has an inner side 21 adapted for leaning against the user and an outer side 22 opposite to the inner side 21. The support member 20 also has a first slot 23, a second slot 24 and a third slot 25, wherein the first slot 23 is a transverse through slot extending from the inner side 21 to the outer side 22 and each of the second slot 24. The second slot 24 and the third slot 25 are inclinedly arranged below the first slot 23 to form a triangular arrangement. The first strap 12 sequentially passes through the first slot 23 and the second slot 24, while the second strap 13 sequentially passes through the first slot 23 and the third slot 25. The first strap 12 and the second strap 13 pass through the first slot 23 in a piling or overlapping manner so as to define a securing region C between the strap unit 11 and the outer side 22 of the support member 20. The height of the securing region C is defined by a distance between a bottom of the first slot 23 and a top of the second slot 24. The second slot 24 has a pair of parallel first hole 241 and second hole 242 each extending from the inner side 21 to the outer side 22 of the support member 20. The first hole 241 and the second hole 242 allow the first strap 12 to sequentially pass through. The third slot 25 has a pair of parallel third hole 251 and fourth hole 252 each extending from the inner side 21 to the outer side 22 of the support member 20. The third hole 251 and the fourth hole 252 allow the second strap 13 to sequentially pass through.

[0032] The lifting ring 30 is arranged on the outer side 22 of the support member 20, wherein the lifting ring 30 has a strap groove 31, matching with the first slot 23 so as to allow both the first strap 12 and the second strap 13 orderly passing through the strap groove 31 and the first slot 23 in an overlapping manner, and has a lifting hole 32 arranged thereon above the strap groove 31 so as for being hung on a hanging spot in the air above the ground t (such as a beam or column of a building, a mounting ring, and etc.).

[0033] The bushing 40 adapted to be transversely arranged at the securing region C has a channel 41 axially formed therein for extending across the securing region C in a transverse direction of the securing region C. The bushing 40 further comprises a L-shaped first hook 42 extended from one end thereof and a L-shaped second hook 43 extended from the other end thereof so as to define and form a slideway 44 between an outer side of the bushing 40 and the first and second hooks 42, 43 for the first strap 12 and the second strap 13 to pass therethrough in an overlapping manner, such that when the bushing 42 bears stress, it can still correspondingly move up and down along the first strap 12 and the second strap 13 within the securing region C and without escaping from the left or right side of the securing region C accidently or informally. The bushing 40 also has a gap 45 defined between the free ends of the first and second hooks 42, 43 for the slideway 44, i.e. about a middle position of the slideway 44 for communicating the inside of the slideway 44 with outside , such that the bushing 40 is able to be detachably mounted on the strap unit 11. Further, the gap 45 is formed in a slant manner, so as to prevent the first strap 12 and the second strap 13 from escaping through the gap 45 easily.

[0034] The connecting device 50 comprises a frame 51 and a latch 52. The frame 51, between two ends thereof, provides and defines a hanging space 53 having an opening 54. The channel 41 of the bushing 40 is adapted to match within the opening 54. The first strap 12 and the second strap 13 pass through the hanging space 53 in a restricted manner. The latch 52 which passes through the channel 41 is installed between two ends of the frame 51 in an openable and closable manner, so as for the connecting device 50 to couple with two anti-falling devices 61 and 62 and to allow the two anti-falling devices 61 and 62 to alternately provide the user different auxiliary hanging points during transverse movement above the ground. Accordingly, when the user accidentally falls, the user is to be hung and supported by means of the anti-falling devices 61 and 62 equipping with the lifting ring 30 and the main hanging spot in the air above the ground in order to wait for rescue.

[0035] In view of above, the present invention has at least the following advantages.

[0036] First, the present invention allows the latch to quickly latch at the securing region directly, which avoids wasting time and efforts on pulling the strap unit and greatly enhances the adaption in mounting and dismounting of the connecting device.

[0037] Second, when the connecting device of the present invention bears walking or falling stresses, the bushing can comply with the stress to move up and down correspondingly within the securing region based on the slidable coupling arrangement between the slideway and the strap unit, so as to effectively mediate and buffer the stress bearing among the latch, the support member, and the strap unit, which greatly reduces the concentration of stress and therefore makes the overall structure and arrangement of the harness unit of the present invention more durable and secure.

[0038] To sum up, the overall structure and arrangement of the present invention is novel and advantageous, which is certainly a great creation of a technical construct and shall match the conditions of patent application. Therefore, it is applied herein in accordance with the law. However, what has been mentioned in the above preferred embodiment is only one of the workable embodiments of the present invention, which shall not be used to limit the scope of the practice of the present invention. In other words, all equivalent alternatives and modifications according to the claims of the present invention shall still be covered by the claimed scope of the present invention.

[0039] One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.

[0040] It will thus be seen that the objects of the present invention have been fully and effectively accomplished. The embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
