Description

Technical Field

[0001] The utility model relates to an auxiliary device for assisting in fixing an object, in particular to a hand-pressing auxiliary device for assisting in fixing wood. Background Art

[0002] There is a safety gripper for electric planer tools disclosed in Chinese invention patent publication number CN106426419A, which includes a handle, a support plate connected to the handle, a steel plate disposed on the bottom surface of the support plate, and four nail anchors disposed on the bottom surface of the steel plate. A user can press the nail anchor against a piece of wood, and hold the handle to push the wood to move on an electric planer tool to plan the wood.

[0003] However, when using the gripper to fix the wood, it is necessary to first apply force to insert the nail anchor into the wood, which is not only very laborious but also causes damage to the wood. In addition, if the nail anchor is not completely inserted into the wood, it is very likely that the nail anchor will be separated from the wood when the gripper is used to move the wood, causing the user's hand to accidentally touch the electric planer, increasing the risk of injury to the user.

[0012] The utility model provides a hand pressure auxiliary device, comprising a substrate, an anti-slip member, a handle, a stop unit, and at least one sliding unit. The substrate comprises an upper side surface, a lower side surface opposite to the upper side surface along the up-down direction, and an opening penetrating the upper side surface and the lower side surface.

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Before the present invention is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.

[0033] See also Figures 1 to 4 The first embodiment of the hand pressure auxiliary device of the utility model comprises a base plate 1, a non-slip member 2, a handle 3, a stop unit 4, and four sliding units 5.

[0034] The base plate 1 includes an upper side surface 11, a lower side surface 12 opposite to the upper side surface 11 along a vertical direction Z, a front end surface 13 connected to the front side of the upper side surface 11 along a front-to-rear direction Y perpendicular to the vertical direction Z, a rear end surface 14 connected to the side of the upper side surface 11 opposite to the front end surface 13, an opening 15 penetrating the upper side surface 11 and the lower side surface 12, and two fixing posts 16 disposed on the upper side surface 11 and located on one side of the base plate 1 along a left-right direction X perpendicular to the vertical direction Z and the front-to-rear direction Y. The fixing posts 16 are spaced apart along the front-to-rear direction Y. A fixing screw hole 161 is formed on the side of each fixing post 16 opposite to the base plate 1.

[0035] The anti-slip member 2 is disposed on the lower side 12 of the substrate 1 and is spaced apart from the opening 15 of the substrate 1 along the left-right direction X. The anti-slip member 2 is an anti-slip rubber pad and has a plurality of evenly distributed and downwardly extending protrusions 21. Each of the protrusions 21 is cylindrical.

[0036] See also Figure 1 ,and Figure 4 The handle 3 is disposed on the upper side 11 of the base plate 1 and extends obliquely upward and toward the direction adjacent to the rear end surface 14. The handle 3 includes two connecting portions 31 connected to the upper side 11 of the base plate 1 at intervals along the left-right direction X, and a gripping portion 32 connected between the connecting portions 31. A wave groove 321 extending along the left-right direction X is formed on the side of the gripping portion 32 facing the base plate 1.

[0037] See also Figure 3 ,and Figure 4 The stopping unit 4 includes a slide seat 41 which is arranged on the upper side surface 11 of the substrate 1 and defines a chamber 411 around the opening 15, a slider 42 which is movably arranged in the chamber 411 along the up-down direction Z, an upper cover 43 covering the chamber 411, two fixing screws 44, and a biasing member 45 which is arranged between the upper cover 43 and the slider 42.

[0038] The slide seat 41 has an inner peripheral surface 412 surrounding the accommodation chamber 411. The accommodation chamber 411 is located above the opening 15 and communicates with the opening 15. The fixing posts 16 are located at two opposite sides of the slide seat 41 along the front-rear direction Y.

[0039] The slider 42 has a top surface 421 facing the upper cover 43 , an outer circumferential surface 422 surrounding and connected to the top surface 421 and facing the inner circumferential surface 412 , and two tube grooves 423 extending downward from the top surface 421 and spaced apart along the front-to-back direction Y.

[0040] The upper cover 43 has a cover body 431 and two lugs 432 connected to two opposite sides of the cover body 431 along the front-to-back direction Y and facing the fixing column 16 respectively. Two mounting grooves 433 spaced apart along the front-to-back direction Y are formed on one side of the cover body 431 facing the chamber 411. The mounting grooves 433 are aligned with the tube grooves 423 respectively.

[0041] The fixing screws 44 pass through the lugs 432 and are screwed into the fixing screw holes 161 .

[0042] The biasing member 45 has two compression springs 451 disposed between the upper cover 43 and the slider 42 and spaced apart along the front-to-back direction Y. The upper end and the lower end of each compression spring 451 are respectively disposed in the corresponding mounting groove 433 and the corresponding pipe groove 423 .

[0043] The sliding units 5 are disposed between the outer circumferential surface 422 of the slider 42 and the inner circumferential surface 412 of the slide seat 41. The sliding units 5 are arranged in groups of two along the left-right direction X and are located at two opposite sides of the slider 42, respectively.

[0044] Each of the sliding units 5 includes a concave surface 51 that is concavely disposed on the inner circumferential surface 412 of the slide seat 41 and defines a groove 52, and a convex block 53 that is convexly disposed on the outer circumferential surface 422 of the slider 42 and can be movably engaged with the groove 52. Each of the grooves 52 extends along the up-down direction Z. Each of the concave surfaces 51 has a limiting surface 511 that is located above the lower side surface 12 of the substrate 1 and adjacent to the bottom of the corresponding groove 52.

[0045] The protrusion 53 can be slidably engaged with the groove 52, so that the slider 42 can slide stably and smoothly. It should be noted that in other variations of this embodiment, the number of the sliding units 5 is not limited, and the sliding units 5 can also be one, two, three or more than five, and are not limited thereto.

[0046] See also Figure 3 ,and Figure 5 , the slider 42 can be switched between a force-bearing position and a non-force-bearing position relative to the substrate 1. When the hand-pressing auxiliary device presses a piece of wood 6 and causes the slider 42 to bear an external force and move to the force-bearing position, the slider 42 is adjacent to the upper cover 43 and does not protrude downward relative to the anti-slip member 2, the protrusions 53 are respectively away from the limiting surface 511, the compression spring 451 is compressed, and the biasing member 45 generates a biasing force applied downward to the slider 42.

[0047] When the external force applied to the slider 42 is removed, the biasing force of the biasing member 45 drives the slider 42 to move to the non-forced position, the slider 42 moves away from the upper cover 43 and protrudes out of the opening 15, and the slider 42 protrudes downward relative to the anti-slip member 2, and the protrusions 53 respectively abut against the limiting surface 511. In this embodiment, the biasing force is the elastic force generated by the compression spring 451 after compression. It should be noted that in other variations of this embodiment, the biasing force can also be generated by other elastic devices or magnetic devices, such as a tension spring or a magnet, but is not limited thereto.

[0048] See also Figure 3 ,and Figure 6 When the wood 6 is placed on a platform (not shown) of a wood planer (not shown) for planing, the user is located at one side of the rear end surface 14 of the base plate 1, holds the handle 3 to press the anti-slip member 2 against the top of the wood 6, and makes the slider 42 abut against the side of the wood 6 to push the wood 6 to move along the platform for planing. At this time, the slider 42 is located at the non-stressed position.

[0049] Since the gripping portion 32 of the handle 3 has the wavy groove 321, it is convenient for the user to grip and apply force and improve the comfort of gripping. In addition, since the user usually stands sideways relative to the wood planer when planing wood, and the handle 3 in this embodiment extends obliquely toward the rear end surface 14 of the base plate 1, it can prevent the user from bending the wrist too much when grasping the gripping portion 32 of the handle 3, and the user can apply force at a comfortable wrist angle to plan wood.

[0050] See also Figure 5 ,and Figure 7 The user can also directly press the entire hand pressure auxiliary device against the wood 6 for use, and at this time the slider 42 is located at the force-bearing position.

[0051] See also Figure 8 and Fig. 9The second embodiment of the hand pressure auxiliary device of the utility model is similar to the first embodiment, and the difference is that the second embodiment includes two stop units 4, and the stop units 4 are arranged on two opposite sides of the base plate 1 along the left-right direction X. Therefore, the user can use the sliders 42 on both sides of the hand pressure auxiliary device to push the wood 6 in two different directions for planing. At this time, the user's left hand (not shown) holds the handle 3 of the second embodiment and makes the slider 42 on the left side abut against the wood 6, so that the anti-slip part 2 and the slider 42 on the right side are pressed against the wood 6, and then the user's right hand (not shown) holds the handle 3 of the first embodiment and presses its anti-slip part 2 and the slider 42 against the wood 6, and the user can use both hands to cooperate to push the wood 6 steadily, and can also achieve the same purpose and effect as the first embodiment.

[0052] See also Figures 10 to 12 The third embodiment of the hand pressure auxiliary device of the present utility model comprises the base plate 1 , the anti-slip member 2 , the handle 3 , two stop units 4 ′, eight sliding units 5 , and two adjustment members 7 .

[0053] The sliding units 5 are arranged in groups of four on the stopper units 4'. To simplify the drawings and descriptions, the stopper unit 4', the adjustment member 7 and the corresponding four sliding units 5 on one side are used for description in this embodiment. The main difference between the third embodiment and the first embodiment is that the slider 42 of the stopper unit 4' further has an adjustment screw hole 424 formed on the top surface 421 and located between the tube grooves 423.

[0054] The upper cover 43 of the stopper unit 4' further comprises an annular wall 434 extending downward from the cover body 431 and surrounding an axis L, and a flange 435 extending from an end of the annular wall 434 opposite to the cover body 431 toward the axis L. The annular wall 434 and the flange 435 together define a through hole 436. The flange 435 comprises an abutting surface 437 facing upwardly toward the through hole 436. The through hole 436 comprises a small aperture portion 438 and a large aperture portion 439 having an aperture larger than the small aperture portion 438 in order from bottom to top.

[0055] The adjusting member 7 includes a connecting portion 71 and a limiting portion 72 connected to the connecting portion 71. The connecting portion 71 passes through the small-diameter portion 438 of the through hole 436 and the abutting surface 437. The connecting portion 71 has an external thread 711 that can be rotatably screwed to the adjusting screw hole 424. The limiting portion 72 is connected to the connecting portion 71 and is located above the upper cover 43. The limiting portion 72 has a snap-on section 721 connected to the connecting portion 71, and a knob 722 connected to the side of the connecting portion 71 opposite to the snap-on section 721. The snap-on section 721 is disposed in the large-diameter portion 439 and is in sliding contact with the annular wall 434. In this embodiment, the connecting portion 71 is a part of a metal screw, and the knob 722 and the snap-on section 721 are made of plastic and are coated with the metal screw by injection molding to form the adjusting member 7.

[0056] In this embodiment, by rotating the knob 722 of the adjusting member 7, the external thread 711 of the connecting portion 71 is rotated relative to the adjusting screw hole 424, so that the slider 42 can be moved closer to or away from the limiting portion 72, and the hand pressure assisting device can be switched between a first use state, a second use state, and a third use state.

[0057] See also Fig.12 ,and Fig.13 When the hand pressure auxiliary device is in the first use state, the slider 42 is away from the limiting portion 72. When the slider 42 is in the non-stressed position, the slider 42 is away from the upper cover 43 and protrudes from the opening 15, and the slider 42 protrudes downward relative to the anti-slip member 2, the abutting section 721 abuts against the abutting surface 437, but the protrusion 53 does not abut against the limiting surface 511. When the slider 42 is subjected to external force and is in the stress-bearing position, the slider 42 is adjacent to the upper cover 43 and does not protrude downward relative to the anti-slip member 2, and the abutting section 721 is spaced from the abutting surface 437 of the upper cover 43.

[0058] See also Fig.14 When the hand-pressing auxiliary device is in the second use state, the slider 42 is adjacent to the limiting portion 72 and does not protrude from the opening 15, and the biasing force of the biasing member 45 cannot drive the slider 42 to move downward so that the slider 42 protrudes downward relative to the anti-slip member 2. In other words, the slider 42 is restricted within the opening 15 and the accommodation chamber 411, and the elastic force of the compression spring 451 cannot drive the slider 42 to pop out of the opening 15. At this time, the hand-pressing auxiliary device can be used as an existing pressure plate with a flat bottom surface.

[0059] See also Fig.15 ,and Fig.16The hand pressure auxiliary device is in the third usage state, which is different from the first state in that the slider 42 is farther away from the limiting portion 72, and when the slider 42 is in the non-stressed position, the protrusion 53 abuts against the limiting surface portion 511, and the downwardly protruding portion of the slider 42 is the largest. When the slider 42 is in the stress-bearing position, the abutting section 721 is farther away from the abutting surface 437.

[0060] In summary, the hand pressure auxiliary device of the utility model can drive the wood 6 to move for planing in a labor-saving and safe manner by holding the handle 3 to press the anti-slip member 2 against the wood 6, and make the slider 42 press against the wood 6 along the left-right direction X, without worrying about the hand accidentally touching the wood planer and getting injured. In addition, another hand pressure auxiliary device can be pressed against the top of the wood 6 for use in cooperation, so as to more stably push the wood 6 for planing, and the use methods are diverse and convenient, so the purpose of the utility model can be achieved.

[0061] The above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
