Description

[Technical Field]

[0001] This invention relates to a parallel frame, and more particularly to a parallel frame for power tool supports. Through the structural design of the parallel frame, the spacing between the position adjustment components can be flexibly adjusted, so that power tools of different sizes can be fixed on the parallel frame. [Previous Technology]

[0002] Note that woodworking involves a large amount of cutting, so power tools such as miter saws or circular saws are needed to assist in cutting wood, thereby increasing cutting efficiency and accuracy. To facilitate portability and reduce storage space, foldable stands are generally used to mount miter saws or circular saws. The stands provide an appropriate height for woodworking, improving the convenience and efficiency of the work. In order to accommodate miter saws or circular saws of different specifications and to meet different work requirements, such as height and width, the stands are now equipped with extendable tables to expand the working area. The stands are also equipped with wheels, making it easy to drag the stands directly to the required work area.

[0003] Chinese Patent Publication No. 204414058 U discloses a folding miter saw workbench, which includes a tabletop and legs. The tabletop is formed by three horizontal tubes fixed together. The legs are located below the tabletop. A fixing seat is provided on the tabletop, which spans across and is fixed to two of the horizontal tubes. Multiple positioning slots and multiple fixing members are provided on the top side of the fixing seat. After the fixing members pass through the positioning slots, the miter saw can be fixed to the fixing seat. However, when installing the miter saw on this workbench, screws need to be inserted from the openings at both ends of the fixing seat, and then the screws need to be tightened by tools or fingers. Since the opening of the fixing seat is not large, the space for tightening the screws is limited. The user needs to hold the nut outside the fixing seat with one hand and tighten the screw inside the fixing seat with the other hand, which makes the operation quite inconvenient. Moreover, if a small miter saw is installed, the screw needs to be moved closer to the center of the fixing seat, making it even more difficult to reach the screw and tighten it.

[0004] Therefore, the inventor has been thinking about how to provide a bracket for conveniently mounting power tools such as miter saws or circular saws, thereby improving the efficiency of fixing power tools. [Summary of the Invention]

[0005] In view of the many shortcomings of the existing power tool brackets, the main purpose of the present invention is to provide a parallel frame that facilitates the installation of power tools. The parallel frame has grooves at different positions to increase the operating range when installing power tools and make the installation operation more convenient.

[0006] To achieve the above-mentioned main objective, the present invention provides a parallel frame for a power tool holder, comprising at least one first positioning groove, at least one second positioning groove, and a plurality of position adjustment components. The first positioning groove is formed on the top side of the parallel frame. The second positioning groove is formed on the side of the parallel frame. Each position adjustment component has a slider and a locking fastener, the end of the slider passing through the second positioning groove, and the locking fastener passing through the first positioning groove and assembled to the slider, thereby allowing the position adjustment components to selectively move along the second positioning groove.

[0007] With the above-mentioned technical features, the user can install two parallel frames on the workbench of the power tool holder, and move the position adjustment component through the first and second positioning slots of the parallel frames. Furthermore, the sliding member of the position adjustment component allows the locking fastener to pass through the first positioning slot and directly engage with the sliding member. Therefore, the user can move the position adjustment component from the outside without using tools or inserting fingers into the interior of the parallel frames, making it a very convenient structural design. Moreover, by adjusting the position of the position adjustment component, the relative distance between the various position adjustment components can be changed, thus allowing for the installation of power tools of different sizes, making the selection of power tools more flexible.

[0008] Preferably, the stand has a movable leg and a fixed leg pivotally connected to the movable leg. One end of the movable leg is pivotally connected to the bottom side of the workbench, and one end of the fixed leg is fixed to the bottom side of the workbench. A set of wheels is provided at the end of the movable leg not connected to the workbench. This provides a convenient dragging design for the movable leg, and the fixed leg can also rotate relative to the movable leg, allowing the entire stand to be folded and stored, making the power tool stand easy to carry without taking up too much storage space.

[0009] Preferably, the workbench includes a support frame having a plurality of support tubes that are interconnected. This method of assembling the support frame using hollow support tubes provides a support platform with sufficient strength and low weight.

[0010] Preferably, the workbench also has at least one extension frame, which has an extension rod, a quick-release assembly disposed on the extension rod, a roller connected to the extension rod, and a stop plate connected to the extension rod. Thereby, one end of the wood can abut against the stop plate or be placed on the roller for fixing or conveying purposes, and the extension tube can extend outward from one end of the workbench to expand the working range to accommodate wood of different sizes.

[0011] Preferably, each parallel frame also includes a fixing component at one end, and a connecting part is provided on the bottom side of each parallel frame, the connecting part abutting against the worktable, and the two parallel frames are detachably assembled to the worktable through the fixing component. Thus, when the fixing component is locked, the parallel frames are clamped and fixed to the worktable, and when the fixing component is unlocked, the parallel frames can move along the worktable, changing the distance between the two parallel frames according to the width of the power tool.

[0012] Preferably, one end of the second positioning groove of the parallel frame is enlarged to form an open through slot. This open through slot provides a larger opening for the slider of the position adjustment assembly to pass through into the interior of the parallel frame, making the installation of the slider more convenient and faster.

[0013] Preferably, a stop block may be selectively provided in the open through slot, the stop block engaging with the side wall of the parallel frame to cover the open through slot. In this way, the stop block prevents the slider from moving into the open through slot of the second positioning slot, thus preventing the slider from separating from the second positioning slot during movement.

[0014] Preferably, each parallel shelf of the worktable has a receiving space for accommodating the position adjustment components, and the receiving space, the first positioning groove, and the second positioning groove are interconnected. Thus, when the position adjustment components are used to secure a power tool, the slider can smoothly move along the second positioning groove to change its position, and then a locking fastener passes through the first positioning groove to engage with the slider.

[0015] Preferably, the slider has a fixing hole and a locking part. The fixing hole penetrates the top and bottom surfaces of the slider, and the locking part is disposed on the top or bottom surface of the slider, or directly formed around the fixing hole of the slider. In this way, the slider is directly provided with a locking part, allowing the locking fastener to be directly fixed to the slider via the first positioning groove of the parallel frame. This eliminates the need for the user to tighten or loosen the locking fastener within the confined working space of the parallel frame.

[0016] Preferably, the end of the slider protrudes outward to form a grip. In this way, the grip can provide a more comfortable grip position, allowing the user to easily apply force to move the position adjustment component.

[0017] The detailed construction, features, assembly, and usage of the parallel frame for power tool supports provided by the present invention will be described in the following detailed description of the embodiments. However, those skilled in the art should understand that such detailed descriptions and the specific embodiments listed for implementing the invention are merely illustrative and not intended to limit the scope of the patent application.

[0018] The applicant first clarifies that in the embodiments and drawings described below, the same reference numerals denote the same or similar elements or their structural features. It should be noted that the elements and structures in the drawings are for illustrative purposes and are not drawn according to actual scale and quantity; and features of different embodiments can be used interchangeably if feasible in practice. Secondly, when it is stated that an element is disposed on another element, it means that the aforementioned element is directly disposed on the other element, or that the aforementioned element is indirectly disposed on the other element; that is, one or more other elements are disposed between the two elements. Conversely, when it is stated that an element is "directly" disposed on another element, it means that no other elements are disposed between the two elements.

[0019] Please refer to Figures 1 and 2. The power tool support 10 of the present invention mainly includes a leg 20, a workbench 30 and two parallel frames 40. In the following embodiments, the power tool is described using a miter saw 50.

[0020] The stand 20 has a movable leg 21 and a fixed leg 22. One end of the movable leg 21 is pivotally connected to the bottom side of the workbench 30, and one end of the fixed leg 22 is fixed to the bottom side of the workbench 30. A wheel set 23 is provided on the end of the movable leg 21 that is not connected to the workbench 30, so that the stand 20 can be moved by the wheel set 23. The center position of the fixed leg 22 is pivotally connected to the center position of the movable leg 21, and the width of the fixed leg 22 is greater than the width of the movable leg 21. Therefore, the fixed leg 22 can be rotated relative to the movable leg 21 to fold for easy storage. In the stored state, the wheel set 23 is on the ground, and the fixed leg 22 and the movable leg 21 are almost perpendicular to the ground and in an upright state, while the workbench 30 is located on the side of the stand 20. Then rotate the fixed foot 22 and the movable foot 21 around the pivot position, so that the fixed foot 22 and the movable foot 21 are in an X-shaped unfolded state. At this time, the wheel set 23 and the end of the fixed foot 22 that is not connected to the workbench 30 are on the ground to support the workbench 30, so that the parallel frame 40 on the workbench 30 can be stably installed with the miter saw 50.

[0021] The workbench 30 is disposed on the top side of the leg 20, and has a support frame 31 and at least one extension frame 33. The support frame 31 has a plurality of support tubes 311, which are arranged side by side and connected to each other to form a support platform. The extension frame 33 has an extension rod 331, a quick-release assembly 332, a roller 333 and a stop plate 334. In the embodiment, two extension frames 33 are used, and one extension frame 33 is correspondingly disposed at one end of a support tube 311. The extension rod 331 of the extension frame 33 can be composed of multiple square tubes of different sizes. The rectangular tube is inserted into one end of the support tube 311 and connected to the rectangular tube of the extension rod 331 through the quick-release assembly 332. In this way, after the quick-release assembly 332 is unlocked, the working range can be adjusted according to the depth of the rectangular tube inserted into the support tube 311. The end of the rectangular tube that is not inserted into the support frame 31 is provided with multiple short square tubes. One of the short square tubes is provided with a roller 333 and a stop plate 334. One end of the wood can be abutted against the stop plate 334 to fix the position of the wood. If the wood is longer, it can be placed on the roller 333, and the roller 333 can assist in the transportation of the wood.

[0022] Please refer to Figures 3 to 6. The parallel frame 40 has at least one first positioning groove 41, at least one second positioning groove 42, a plurality of position adjustment components 43, and a fixing component 44. The parallel frame 40 has a U-shaped hollow structure, and its interior forms an accommodating space 45, which is interconnected with the first positioning groove 41 and the second positioning groove 42. The U-shaped opening of the parallel frame 40 serves as the bottom side, and a connecting part 46 is recessed in this part. The parallel frame 40 spans the support frame 31 of the workbench through the connecting part 46, and the connecting part 46 abuts against the outer surface of the support tubes 311 of the support frame 31.

[0023] In this embodiment, two first positioning grooves 41 are formed on the top side of a parallel frame 40, and two second positioning grooves 42 are formed on the left and right sides respectively, for a total of four second positioning grooves 42. However, the present invention does not limit the number of first positioning grooves 41 and second positioning grooves 42 of a single parallel frame 40. It is also possible to form a first positioning groove 41 with an extended length on the top side of a single parallel frame 40 and a second positioning groove 42 with an extended length on the left and right sides respectively. Alternatively, a second positioning groove 42 with an extended length can be formed on a single side of the parallel frame 40.

[0024] Furthermore, the fixing component 44 is disposed at one end of the parallel frame 40. It controls the locking or unlocking state of the parallel frame 40 through a combination of a clamp and a handle 441. The clamp is accommodated in the receiving space 45 inside the parallel frame 40. The handle 441 is connected to the clamp and is exposed from the opening at one end of the parallel frame 40, allowing the user to operate the handle 441 to control the clamp. By holding the handle 441, it is convenient to move the entire parallel frame 40 left and right along the support tube 311 of the support frame 31 to adjust the distance between the two parallel frames 40.

[0025] The position adjustment assembly 43 has a slider 431 and a locking fastener 432, the locking fastener 432 being, for example, a bolt. The slider 431 is accommodated in the receiving space 45 of the parallel frame 40, and its two ends protrude from the second positioning grooves 42 on different sides. The end of the slider 431 protruding from the second positioning grooves 42 is bent downward to engage with the left and right sides of the parallel frame 40, so that the slider 431 will not easily fall off when moving along the second positioning grooves 42. The slider 431 also has a fixing hole 4311 and a locking part 4312. The fixing hole 4311 penetrates the top and bottom surfaces of the slider 431. The locking part 4312 can be, for example, a nut, welded to the top or bottom surface of the slider 431, or for example, threads can be formed directly around the fixing hole 4311, so that when the locking fastener 432 passes through the first positioning groove 41, it can be directly locked into the threads around the fixing hole 4311 of the slider 431.

[0026] Wherein, if the parallel frame 40 forms only one second positioning groove 42, the slider 431 will have only one end that extends to the length that can pass through the second positioning groove 42, while the length of the other end will be shorter so that it can be accommodated in the receiving space 45 inside the parallel frame 40.

[0027] When actually installing the miter saw 50, the miter saw 50 is placed on the parallel frame 40. Generally, the base of the miter saw 50 has four locking points. Therefore, during implementation, four position adjustment components 43 are also set in the two parallel frames 40. Each parallel frame 40 is equipped with two position adjustment components 43. The user needs to move the position adjustment components 43 according to the locking points of the miter saw 50.

[0028] The user moves the slider 431 along the second positioning groove 42 through both ends of the slider 431. When the fixing holes 4311 of the four sliders 431 are aligned with the locking points of the miter saw 50, the locking fastener 432 is passed through the locking points of the miter saw 50 from top to bottom, and then through the first positioning groove 41 of the parallel frame 40 until it reaches the position of the fixing holes 4311 of the slider 431 and the locking part 4312. Then the locking fastener 432 can be tightened. Since the locking part 4312 is directly connected to the slider 431, and both ends of the slider 431 protrude from the second positioning groove 42, the user does not need to put one hand into the parallel frame 40 to hold the slider 431 when tightening or loosening the locking fastener 432. Instead, the user can hold the slider 431 directly from the outside of the parallel frame 40. This makes the installation and positioning of the miter saw 50 very convenient and quick.

[0029] Furthermore, please refer to Figure 7 again. One end of the second positioning groove 42 of the parallel frame 40 can, for example, form an open through groove 421, which is larger than the second positioning groove 42 and is connected to the second positioning groove 42. Through the open through groove 421, the slider 431 of the position adjustment component 43 can be directly inserted into the inside of the parallel frame 40, so that one end of the slider 431 is engaged with one side of the parallel frame 40 and the other end is engaged with the other side of the parallel frame 40. Then the slider 431 is moved to the position of the second positioning groove 42, so that the slider 431 can be easily installed.

[0030] However, in order to prevent the slider 431 from accidentally moving to the open slot 421 during use and separating from the open slot 421, a stop block 60 is provided corresponding to the shape of the open slot 421. After the slider 431 is inserted, the stop block 60 can be installed at the position of the open slot. A groove 61 is formed in the middle of the stop block 60. The stop block 60 is clamped to the side wall of the parallel frame 40 through the groove 61 and the open slot 421 is covered. At this time, the remaining space in the open slot 421 is insufficient for the slider 431 to be taken out, effectively preventing the slider 431 from separating from the parallel frame 40.

[0031] Please refer to Figure 8 again. In order to move the slider 431 of the position adjustment component 43 more easily, the slider 431 may protrude outward at both ends to form a grip 4313, so that the user can hold the grip 4313 at one end with his / her fingers to move the slider 431. Alternatively, the user can place two fingers across the top side of the parallel frame 40 and then press against the grip 4313 at both ends of the slider 431 to move the slider 431 by pushing. This allows the user to adjust the slider 431 of the position adjustment component 43 in a comfortable and easy-to-apply posture.

[0032] In summary, the parallel frame for power tool holder 10 provided by the present invention has at least the following advantages compared with the prior art:

[0033] 1. The parallel frame of the present invention utilizes the design of the second positioning groove 42 of the parallel frame 40 to allow the user to easily move and adjust the position of the sliding member 431 of the component 43 to a suitable position according to the size of the miter saw 50, and then fix the miter saw 50 through the first positioning groove 41 to achieve the advantage of rapid positioning.

[0034] 2. In the parallel frame of the present invention, the locking fastener 432 can be directly connected to the sliding member 431, and the two ends of the sliding member 431 will pass through the second positioning groove 42 of the parallel frame 40. In this way, when installing the miter saw 50, the user does not need to put the tool or fingers into the narrow space of the parallel frame 40. The sliding member 431 can be held from the outside of the parallel frame 40, and the locking fastener 432 can be easily aligned with the sliding member 431 to fix the miter saw 50, making the installation process of the power tool more convenient.

[0035] Finally, it must be stated again that the constituent elements disclosed in the above-mentioned embodiments of the present invention are merely illustrative examples and are not intended to limit the scope of this application. Substitutions or variations of other equivalent elements should also be covered by the scope of the patent application of this application. [Simplified Explanation of the Diagram]
