RECYCLING-FRIENDLY GARDENING SHEARS

Abstract

Recycling-friendly gardening shears include a metallic unit and a nonmetallic unit. The metallic unit has metallic components. At least one of the metallic components has an engagement space. The nonmetallic unit has engaging portions. The metallic components are smoothly coupled to the nonmetallic unit as soon as the engagement spaces engage with the engaging portions. When the gardening shears are no longer usable and thus are suitable for recycling, a user only needs to exert a simple pull to separate the engaging portions quickly from the engagement spaces and thus conveniently detach the nonmetallic unit from the metallic components. The gardening shears include a metallic unit and a nonmetallic unit. The metallic unit has metallic components, such as a gardening shear body, resilient element, block, spring, and positioning pin. The nonmetallic unit has two pads, a buffer and a knob which are mounted on the gardening shear body.

DETAILED DESCRIPTION

[0016] Objectives, features, and advantages of the disclosure are herein illustrated with embodiments, depicted with drawings, and described below.

[0017] Referring to FIG. 1 through FIG. 4, the disclosure provides recycling-friendly gardening shears comprising a metallic unit (10) and a nonmetallic unit (20). The metallic unit (10) has metallic components. At least one of the metallic components has an engagement space (101). The nonmetallic unit (20) has engaging portions (201). The metallic components are smoothly coupled to the nonmetallic unit (20) as soon as the engagement spaces (101) engage with the engaging portions (201). When the gardening shears are no longer usable and thus are suitable for recycling, a user only needs to exert a simple pull to separate the engaging portions (201) quickly from the engagement spaces (101) and thus conveniently detach the nonmetallic unit (20) from the metallic components (as shown in FIG. 5 through FIG. 7). The metallic unit (10) comprises metallic components, such as a gardening shear body (11), a resilient element (12), a block (13), a spring (14) and a positioning pin (15). The nonmetallic unit (20) comprises two pads (21), a buffer (22) and a knob (23) which are mounted on the gardening shear body (11). The gardening shear body (11) has two handles (111) pivotally connected to each other. A blade (112) is connected to each of the two handles (111). Under a force applied to the two handles (111), the two blades (112) are opened and closed to perform a cutting process. The engagement spaces (101) are defined at multiple points on the two handles (111) respectively. The resilient element (12) is mounted in place between the two handles (111). One of the blades (112) has a limitative notch (1121). One of the handles (111) has a slot (1111) in which the block (13), the spring (14) and the positioning pin (15) are mounted in place. When the two blades (112) are closed, the knob (23) coupled to the gardening shear body (11) drives the block (13) protruding out of the slot (1111) and then further entering the limitative notch (1121) to cause the blades (112) to stay in a closed state. The positioning pin (15) is pushed by the spring (14) to preclude displacement of the block (13), and thus the block (13) is fixed in place at a protruded position or a retracted position. The engaging portions (201) are disposed on the pads (21), the buffer (22) and the knob (23) respectively. Owing to the resilience of the nonmetallic unit (20), the engaging portions (201) compressed get fitted inside the engagement spaces (101) respectively, allowing the pads (21), the buffer (22) and the knob (23) to be fully coupled to the gardening shear body (11).

[0018] The disclosure provides recycling-friendly gardening shears, wherein the resilient element (12) is a compression spring formed by winding a metal wire.

[0019] The disclosure provides recycling-friendly gardening shears, wherein the resilient element (12) is a barrel spring formed by winding a metal plate.

[0020] The disclosure provides recycling-friendly gardening shears, wherein the pads (21), the buffer (22) and the knob (23) are made of plastic.

[0021] The disclosure provides recycling-friendly gardening shears, wherein the pads (21), the buffer (22) and the knob (23) are made of rubber.

[0022] The disclosure provides recycling-friendly gardening shears, wherein the engaging portions (201) on the pads (21) are ribs, and the engagement spaces (101) for engaging with the engaging portions (201) are engaging grooves.

[0023] The disclosure provides recycling-friendly gardening shears, wherein the engaging portions (201) on the buffer (22) are engaging posts, and the engagement spaces (101) for engaging with the engaging portions (201) are engaging holes.

[0024] The disclosure provides recycling-friendly gardening shears, wherein the engaging portions (201) on the knob (23) are ribs, and the engagement spaces (101) for engaging with the engaging portions (201) are engaging grooves. The engaging grooves are larger than the knob (23), allowing the knob (23) to be pushed to undergo translational motion after having engaged with the handles (111).

[0025] The disclosure provides recycling-friendly gardening shears characterized in that the outer surface of at least one of the pads (21) is covered with a vibration-absorbing layer (24) to enhance the comfortableness of the gardening shear body (11).

[0026] The disclosure provides recycling-friendly gardening shears characterized by a positioning post (231) disposed on the knob (23) and a positioning hole (131) disposed on the block (13), with the positioning post (231) penetratingly fixed to the positioning hole (131), such that the knob (23) and the block (13) are linked to each other, allowing the knob (23) to drive the block (13) undergoing translational motion.

[0027] The advantages of the aforesaid specific embodiment are described below. To recycle the gardening shears, a user only needs to exert a simple pull to separate the engaging portions (201) quickly from the engagement spaces (101) and thus conveniently detach the nonmetallic unit (20) from the gardening shear body (11). The aforesaid detachment process dispenses with a damaging means and thus is conducive to the minimization of the difficulties in recycling, the required manpower and the incurred cost and the enhancement of recycling dealers incentive to recycle the gardening shears. When effectively recycled, the gardening shears can keep pace with the global trend toward net-zero carbon emissions and thus avoid flagging sales, boycotts, and a weak competitive position.

[0028] In conclusion, the disclosure provides radical innovation and thus improves on the prior art. In addition, the disclosure has high industrial applicability and involves an inventive step. Furthermore, the disclosure has never been published and has novelty.

[0029] The disclosure is disclosed above by preferred embodiments. However, persons skilled in the art should understand that the embodiments are illustrative of the disclosure only, but shall not be interpreted as restrictive of the scope of the disclosure. Please note that all variations and modifications equivalent to the embodiments shall be deemed falling within the scope of the disclosure.
