Fig. 15 is a front view of the hand tool according to yet another embodiment.
The present disclosure provides a hinge assembly. The hinge assembly can be applied to a tool that has a first acting member and a second member.
The hinge assembly includes a hinge and a detent cover. The hinge is pivotally connected a first acting member to a second acting member of the tool.
The detent cover can cover the hinge to stop the rotational motion between the first acting member and the second acting member. Therefore, the user can drive the different positions of the work piece.
Fig. I is a front view of a pair of pliers 100 according to one embodiment, wherein the hinge assembly is applied to the pair of pliers 100. Fig. 2 is a side view of the pair of pliers 100 of Fig. 1. The pair of pliers 100 includes a first lever 110, a second lever 120 and at least one detent cover 130. The second lever 120 is pivotally connected to the first lever 110. The second lever 120 includes a jaw 122, a handle 124 and a hinge 126. The hinge 126 pivotally connects the jaw 122 to the handle 124. The detent cover 130 is pivotally connected to the jaw 122 of the second lever 120. The detent cover 130 can cover the hinge 126 to stop the rotational motion between the handle 124 and the jaw 122.
Fig. 3 is a front view of the pliers 100 of Fig. 1 in use. In use, the user can cover the detent cover 130 to the hinge 126 from the outer side of the second lever 120. Therefore, when the user drives the work piece with the pair of pliers 100, the handle 124 and the jaw 122 can't be pivoted.
In addition, the pair of pliers 100 of Fig. I further includes a spring 101.
The spring 101 restorably connects the first lever 110 and the second lever 120.
Fig. 4 is a front view of a pair of pliers 100 according to another io embodiment. In Fig. 4, the first lever 110 of the pair of pliers 100 also includes a jaw 112, a handle 114 and a hinge 116. The hinge 116 pivotally connects the jaw 112 to the hande 114. Therefore, it is more practical for the user to adjust the acting angle with both the first lever 110 and the second lever 120.
In Fig. 4, the detent cover 130 is positioned to cover the hinge 126 from the inner side of the second lever 120. The second level 120 further includes a cover slot 128. When the detent cover 130 is covered the hinge 126, the detent cover 130 can be positioned in the cover slot 128. Therefore, the detent cover 130 would not protrude from the inner side of the second lever 120.
Fig. 5 is a front view of a pair of pliers 100 according to yet another embodiment. Fig. 6 is a front view of the pair of pliers 100 of Fig. 5 in use. In Fig. 5 and Fig. 6, two detent covers 130 are pivotally connected to the handle 114 of the first lever 110 and the handle 124 of the second lever 120 respectively. The detent covers 130 are positioned to cover the hinges 116, 126 from the inner side of the first lever 110 and the inner side of the second lever 120 respectively. The rotational motion between the handle 114 and jaw 112 of the first lever 110 and the handle 124 and the jaw 122 of the second lever 120 can be arrested by the detent covers 130.
In addition, the first level 110 and the second level 120 each includes a cover slot 118, 128. Therefore, the detent covers 130 can be positioned in the cover slots 118, 128 respectively.
Fig. 7 is a three dimensional view of a pair of pliers 100 according to still another embodiment. In Fig. 7, the pair of pliers 100 further includes a slot 140.
The slot 140 is located in the side surface of the second lever 120. In detail, the slot 140 is located in the side surface of the jaw 122. The slot 140 can mesh the detent cover 130 when the jaw 122 and the handle 124 reach a predetermined angle relative to each other.
Fig. 8 is a front view of a pair of pliers 100 according to yet another embodiment. In Fig. 8, the pair of pliers 100 includes a plurality of the slots 140. The slots 140 are located in the side surface of the first lever 110 and the is second lever 120. In use, the user can mesh the detent covers 130 by the slots 140. Both of the first lever 110 and the second lever 120 include two slots 140. Therefore, the user can set different predetermined angles between the jaw 112 and the handle 114 of the first lever 110 and the jaw 122 and the handle 124 of the second lever 120.
Fig. 9 and Fig. 10 are side views of the pair of pliers 100 of Fig. 8. In detail, the user can rotate the handle 124 of the second lever 120 to a predetermined angle relative to the jaw 122 of the second lever 120. Then, the user can mesh the detent cover 130 in one of the slots 140. Therefore, the predetermined angle between the jaw 122 and the handle 124 is stably set.
Fig. ills a front view of the pair of pliers 100 according to still another embodiment. In Fig. ii, the pair of pliers 100 further includes a plurality of the slots 150. The slots 150 are located in the detent covers 130. The slot 150 can mesh the second lever 120 when the jaw 122 and the handle 124 reach a predetermined angle relative to each other. In addition, the slot 150 also can mesh the first lever 110 when the jaw 112 and the handle 114 reach a predetermined angle relative to each other.
Fig. 12 is a front view of a hand tool according to yet another embodiment, wherein the hinge assembly is applied to the hand tool such as a io wrench 200. Fig. 13 is a front view of the hand tool of Fig. 12 in use. The wrench 200 includes a handle 210, an acting member 220, a hinge 230 and a detent cover 240.
