Description

Technical Field

[0001] The present invention relates to a pressing tool that can easily and reliably fix a shelf post member to a building wall such as a gypsum board or a plywood board with a predetermined mounting strength.

Background Art

[0002] In recent years, the number of houses with gypsum boards has increased, and the number of DIY users who make use of building walls made of gypsum boards according to their own preferences is also growing. For example, after a U-shaped cross-section shelf post provided with rectangular holes at appropriate positions is fixed to a gypsum board, the base end of a linear thin plate-shaped bracket is engaged with the rectangular hole of this shelf post, and the bracket supported at a single point can be used for purposes such as hanging a children's clothes hanger. It is also conceivable to fix a pair of left and right shelf posts to a gypsum board, and hold a shelf board by brackets that are each supported at a single point on the left and right shelf posts.

Summary of Invention

Problems to be Solved by the Invention

[0004] Patent documents 1 to 3 describe a method for attaching a shallowly bent metal shelf support to plasterboard along with a plastic mounting member. However, these inventions require inserting a needle member into the plasterboard through the mounting member held in the opening of the shelf support. Therefore, for DIY users unfamiliar with this type of work, it is not easy to maintain the long shelf support in a perfectly vertical position during installation, and incomplete installation often results in unsatisfactory results.

[0005] Furthermore, in the configurations described in Patent Documents 1 to 3, from the viewpoint of mounting strength, it is not possible to create a large distance between the surface of the shelf post and the building wall. Therefore, although it is possible to hang children's clothing hangers on the shelf post after it has been fixed, it is not possible to engage the base end of a plate-shaped bracket, which requires a certain length, with the shelf post.

[0006] Furthermore, in the configurations of Patent Documents 1 to 3, even if the bending height of the shelf support is set high, if an unintended strong force is applied in the lateral direction, such as when a resident's arm hits the bracket supported at a single point on the shelf support, there is a risk that the open end of the U-shaped shelf support may sink into the gypsum board. This point is basically the same even in the configuration of Prior Art Document 4, which has a different application.

[0007] Incidentally, in order to ensure the strength of attachment to the gypsum board, there is a proposal to insert a flat, plate-shaped first pin with an elongated hole at its tip in an inclined direction, and then insert a needle-shaped second pin vertically, so that the tip of the second pin passes through the elongated hole of the first pin (Patent Documents 5-7). However, if the insertion direction of the first pin is incorrect, the tip of the second pin cannot be passed through the elongated hole of the first pin, and DIY users in particular are not uncommon to fail at this task. If the insertion work fails, it is necessary to reinsert the first pin in the correct direction, but this requires the additional work of filling the initial hole that was made too wide with filler and allowing the filler to dry, and in some cases, repeating this work will only result in an increase in meaningless repair holes in the gypsum board.

[0008] Furthermore, regardless of the configuration, it is necessary to drive pins into the building wall using, for example, a small hammer, and if this process is unsuccessful, it will only result in more meaningless holes. In particular, for DIY users who are unfamiliar with this type of work, there is a need for a pressing device that can easily and reliably fix shelf support members to building walls such as plasterboard or plywood with the required mounting strength.

[0009] The present invention has been made in view of the above problems, and aims to provide a pressing device that has a predetermined mounting strength and can easily and reliably fix a predetermined shelf support member to a building wall. [Means for solving the problem]

[0010] To achieve the above objective, the present invention provides a pressing device (PRS) for passing a fixing pin (PN) through guide holes (HO1~HO3) of a fixing member (3) fitted into an opening in a plate material, and for pushing the fixing pin (PN) that has passed through the fixing member (3) into a building wall (WALL), comprising a substantially cylindrical main body (5) that gradually or continuously decreases in diameter from the base end towards the tip, and a flattened tip (6) extending from the main body (5), wherein the tip (6) has a plurality of cylindrical holes (RV1~RV3) of different depths that can receive the head of the fixing pin (PN). [Effects of the Invention]

[0011] According to the pressing device of the present invention described above, suitable shelf support members can be easily and reliably fixed to the building wall with a predetermined mounting strength. [Brief explanation of the drawing]

[0012] [Figure 1] This is a diagram illustrating the components of the shelf support member PL according to the embodiment. [Figure 2] Figure 1 is a detailed drawing of the fixing member 3 shown in Figure 1. [Figure 3] This is a diagram illustrating the assembly procedure and usage of the shelf support member PL. [Figure 4] This is a drawing for explaining the pressing tool PRS used when assembling the shelf post member PL. [Figure 5] This is a drawing for explaining the additional member of the pressing tool PRS. [Figure 6] This is a drawing for explaining the extraction fitting RJ used when removing the shelf post member. [Mode for Carrying Out the Invention]

[0013] Hereinafter, the present invention will be described in detail based on examples. Figure 1 and Figure 2 illustrate the constituent elements of the shelf post member PL according to the example, showing an abutment plate 1 that is pressed against the building wall WALL, a face plate 2 with a U-shaped cross section that covers the abutment plate 1, a fixing member 3 that fits into the fitting holes 10a, 10b of the abutment plate 1, and closing members 4 that block both upper and lower ends of the face plate 2. Although not particularly limited, the building wall WALL to which this example is applied is preferably composed of a gypsum board with a plate thickness of about 9 to 15 mm, or a plywood board with a plate thickness of 6 mm or less.

[0014] The abutment plate 1 is composed of, for example, an aluminum plate with a left-right width of about 12 mm, a length of about 500 to 2000 mm, and a plate thickness of about 3 mm. The abutment plate 1 is formed with one fitting hole 10a, 10a adjacent to each of the upper and lower ends, and one or a plurality of fitting holes 10b arranged at appropriate equal intervals (for example, 225 mm) between the fitting holes 10a, 10a.

[0015] The fitting holes 10a, 10b are configured as long holes of the same shape that are slightly elongated in the vertical direction and penetrate the plate surface, and one side (the right side in the drawing) in front view thereof has a slightly bulging shape. This bulging shape corresponds to the shape of the recessed portion 3A of the fixing member 3, and functions to specify the vertical direction when the abutment plate 1 is mounted, as well as to specify the fitting direction of the fixing member 3.

[0016] In the vicinity of the fitting holes 10a, 10b configured as described above, a plurality of tapped holes 11a, 11b provided with screw grooves are formed in a vertical line at the center of the plate surface of the abutment plate 1 of the embodiment. All the tapped holes 11a, 11b have the same configuration, and are roughly divided into the tapped holes 11a, 11a located outside the fitting hole 10a and the other tapped holes 11b to 11b according to their applications. Here, the tapped holes 11a are used for fixing the closing member 4 to the face plate 2, and the other tapped holes 11b are used for fixing the face plate 2 to the abutment plate 1.

[0017] The face plate 2 is made of, for example, a steel material, and as shown in Fig. 1(b), it is formed into a U-shaped cross section by a top piece 2A and projecting pieces 2B, 2B orthogonal to both sides of the top piece 2A. Here, the lateral width W of the top piece 2A is set to be narrower than the lateral width of the abutment plate 1, and the height H of the projecting pieces 2B, 2B is set to be higher than the lateral width W of the top piece 2A. Further, the vertical length of the face plate 2 is set to be slightly shorter than the vertical length of the abutment plate 1. For example, when N appropriate types of the abutment plate 1 having a length in the range of 500 to 2000 mm are prepared, N types of the face plate 2 that are slightly shorter than the corresponding abutment plate 1 are also prepared for each abutment plate 1.

[0018] In any of the face plates 2, a plurality of slightly vertically long rectangular holes 20 are formed in a line at equal intervals on the top piece 2A thereof. The rectangular holes 20 are used for locking the base end portion of a flat plate-shaped bracket BR. Further, a plurality of countersunk holes 21 corresponding to the tapped holes 11b of the abutment plate 1 are formed in the top piece 2A of the face plate 2. Each of the countersunk holes 21 to 21 is used for allowing a mounting screw SC for integrating the face plate 2 and the abutment plate 1 to pass therethrough.

[0019] The fixing member 3 is a one-piece molded plastic product and has the shape shown in Figures 1(c) and 2. As shown in the figures, the fixing member 3 is broadly divided into a recessed portion 3A that is housed in the fitting holes 10a and 10b when in use, and an exposed portion 3B that is exposed from the contact plate 1. The recessed portion 3A has a bulging portion 30c that is almost the same as the contour shape of the fitting holes 10a and 10b, and is configured to fit into the fitting holes 10 without force. The depth dimension of the recessed portion 3A is formed to be almost the same as the thickness of the contact plate 1.

[0020] On the other hand, the exposed portion 3B is configured as a roughly rectangular raised mound, and its vertical dimension is set to be longer than the major axis of the fitting hole 10. Furthermore, the lower surfaces of the upper 30a and lower 30b of the exposed portion 3B are formed flat, so that the fixing member 3 fits into the fitting hole 10 of the contact plate 1 without any gaps.

[0021] Furthermore, the fixing member 3 has three guide holes HOi (HO1~HO3) formed in an inclined direction, which penetrate the exposed portion 3B and the recessed portion 3A to guide the passage of the mounting screws SC. As shown by the dashed lines in Figures 2(a) and 2(b), guide hole HO1 opens at an inclination angle of approximately 80 degrees toward the upper right of the figure. Guide hole HO2 opens at an inclination angle of approximately 60 degrees toward the lower left, and guide hole HO3 opens at an inclination angle of approximately 70 degrees toward the lower right.

[0022] As shown in Figure 2(a), the upper and lower guide holes HO1 and H03 are positioned slightly to the left of the center line, while the central guide hole HO2 is positioned slightly to the right of the center line. Therefore, even when the fixing pin PN is passed through the three guide holes HO1 to HO3, the tips of the fixing pins PN, PN do not interfere with each other.

[0023] Next, the closing member 4 is made of a roughly rectangular parallelepiped-shaped plastic material and is formed to be slightly larger in the width and height directions compared to the surface plate 2. A mounting hole 40 for screwing mounting screws SC into the contact plate 1 is formed through its center, and one end face 41 in the vertical direction is open to receive the gate-shaped end of the surface plate 2 and conceal the exposed end face of the surface plate 2.

[0024] Figure 3(a) shows the abutment plate 1 fixed to the building wall, and Figures 3(b) and 3(c) show the completed shelf support member PL. To complete the shelf support member PL, first, the fixing member 3 is fitted into the fitting holes 10a and 10b of the abutment plate 1, and fixing pins PN are driven into the guide holes HO1 to HO3 of the abutment plate 1, which is maintained in a vertical position.

[0025] The fixing pin PN is composed of a large-diameter head, a round bar-shaped shaft, and a pointed needle-like tip. It is inserted until all parts except the head are embedded in the fixing member 3. Figure 3(a) shows the state in which the contact plate 1 is fixed to the building wall after this insertion process.

[0026] Next, the surface plate 2 is placed over the contact plate 1, mounting screws SC are inserted into the countersunk holes 21-21 of the surface plate 2, and the mounting screws SC are screwed into the tapped holes 11b-11b of the contact plate 1. Then, the closing members 4 are placed at the upper and lower ends of the surface plate 2, and the mounting screws SC, which have passed through the mounting holes 40 of the closing members 4, are screwed into the tapped holes 11a of the contact plate 1, thereby fixing the shelf support member PL to the building wall WALL.

[0027] As shown in Figure 3(b), in the completed shelf support member PL, the upper and lower end faces of the surface plate 2 are concealed by the closing member 4, resulting in a neat mounting position and preventing injuries from exposed end faces.

[0028] Furthermore, in the shelf support member PL of this embodiment, as shown in Figure 3(c), a sufficient gap is secured between the top piece 2A of the surface plate 2 and the contact plate 1, so that the base piece of the hook-shaped bracket BR can be easily locked into the rectangular hole 20 of the surface plate 2. A clothes hanger can be hung from this bracket BR, for example, and if a pair of shelf support members PL, PL are fixed in left and right positions, a shelf can be held by the left and right pair of brackets BR, BR locked to each shelf support member PL.

[0029] In this type of use, a strong, unintended force may be applied to the bracket BR protruding from the shelf support member PL, such as when a resident's arm hits it. However, in the shelf support member PL of this embodiment, the contact plate 1, which is wider than the surface plate 2, receives the pressure from the surface plate 2, and moreover, this contact plate 1 is in surface contact with the building wall WALL, so the end of the shelf support member PL will not sink into the gypsum board or the like.

[0030] As described above, the shelf support member PL of the embodiment exhibits excellent effects, but for DIY users, the task of fixing the contact plate 1 to the building wall WALL is not necessarily easy. Therefore, such DIY users prefer to use the pressing device PRS shown in Figures 4 and 5.

[0031] As shown in Figures 4(d) and 4(e), this pressing device PRS is composed of a roughly cylindrical main body portion 5 (5A to 5C) that decreases in diameter in three stages from the base end towards the tip, a flattened tip portion 6 that extends from the small-diameter main body portion 5C at the tip end, and a base end cap 7 that fits onto the large-diameter main body portion 5A at the base end. Here, a projection PR is formed on the outer circumference of the large-diameter main body portion 5A, extending in the axial direction (the length direction of the main body portion) to ensure secure fitting of the base end cap 7 (Figure 4(a)). On the other hand, a notched groove GV is formed in the axial direction on the small-diameter main body portion 5C, which serves the functions of positioning during operation and preventing slippage (Figure 4(d)).

[0032] The tip 6 of the pressing device PRS has cylindrical holes RV1 to RV3, which are aligned on a flattened central line and capable of receiving or pressing the head of the fixing pin PN. Of the three cylindrical holes RV1 to RV3, the central cylindrical hole RV1 is formed to be the deepest, preferably to a depth in which at least 1 / 4 (more preferably at least 1 / 3) of the total length of the fixing pin PN is immersed. On the other hand, the other cylindrical holes RV2 and RV3 are formed to be sufficiently shallower than the central cylindrical hole RV1. The cylindrical holes RV3 and RV2 can be appropriately selected according to the thickness of the head of the fixing pin PN, and can be arbitrarily selected according to the hardness of the building wall WALL and the length of the fixing pin PN before final insertion.

[0033] When using the pressing device PRS having the above configuration, first insert the fixing pin PN into the cylindrical hole RV1 with its head first, and then, for example, hold the main shaft of the fixing pin PN with your thumb and grasp the pressing device PRS (see Figure 4(f)). Next, insert the fixing pin PN, which is being pressed with your thumb or the like, into the guide hole HOi (any of HO1 to HO3) of the fixing member 3, and push it firmly along the guide hole HOi to push the fixing pin PN to the limit position of the cylindrical hole RV1. Since the tip 6 of the pressing device PRS in this embodiment has a flat shape, the above work is easy when the fixing pin PN is being pressed.

[0034] Furthermore, since the depth of the cylindrical hole RV1 is at least 1 / 3 (preferably at least 1 / 2) of the total length of the fixing pin PN, the exposed length of the fixing pin PN after the above work will be 2 / 3 or less (preferably 1 / 2 or less) of the total length of the fixing pin PN. The above work is a temporary fixing work for the fixing pin PN, but a sufficient length is inserted into the building wall WALL, and the subsequent insertion work is an additional pressing work and is relatively easy.

[0035] The subsequent work procedure is optional, but for example, after performing temporary fastening work on all guide holes HO1 to HO3 in order, the head of the exposed fixing pin PN is inserted into the shallowest cylindrical hole RV3 or the deeper cylindrical hole RV2, and then the fixing pin PN is pushed in to its final position.

[0036] For relatively soft building walls such as gypsum board, the above pressing operation can be performed using the shallowest cylindrical hole RV3. On the other hand, when inserting fixing pins into building walls made of plywood, it is also preferable to use the cylindrical hole RV2. Considering these points, it is preferable that the pressing device PRS of the embodiment be sold with an instruction manual that includes, for example, the contents of Figure 4(f).

[0037] In any case, by using the pressing tool PRS of the embodiment, it becomes unnecessary to strike the fixing pin PN with a hammer or the like, so even inexperienced DIY users can install the shelf board member PL without fail. However, the pressing tool PRS shown in Figure 4 may sometimes feel that its axial length is insufficient. In such cases, the joint member JT shown in Figure 5 can be used. This joint member JT has a cylindrical shape in which the diameter is reduced in two stages, and is divided into a main body JTa with a protruding ridge PR and a tip JTb which is a cylinder split in two.

[0038] The tip portion JTb of the joint member JT in the embodiment is constructed by splitting a cylinder in half, allowing for some degree of radial contraction. Therefore, when in use, the tip portion JTb of the joint member JT can be easily inserted into the large-diameter main body portion 5A of the pressing device PRS, and then the base end cap 7 can be placed over the main body portion JTa to secure the axial length of the pressing device PRS.

[0039] Furthermore, there are times when you want to remove a shelf support member PL that has already been installed, or move it to a different location. Also, shelf support members PL installed in a rented house need to be neatly removed when moving out. In such cases, it is necessary to properly pull out the fixing pin PN, and for such purposes, the pull-out fittings RJ1 and RJ2 shown in Figure 6 are suitably used.

[0040] The RJ1 extraction fitting is made of a metal plate bent into an L-shape in cross-section, and has a V-shaped groove at its tip for hooking the head of the fixing pin PN. The body of the RJ1 extraction fitting also has multiple rows of widthwise protrusions formed along its length to provide an anti-slip function.

[0041] On the other hand, the slightly smaller extraction fitting RJ2 is constructed in a straight S shape by bending the tip and base of the plate material in opposite directions. A V-shaped groove is formed at the tip for hooking the head of the fixing pin PN, and a projection extending in the longitudinal direction is formed on the main body. It is preferable that when the extraction fittings RJ1 and RJ2 are sold, an instruction manual describing the contents of Figure 6(b), for example, is attached.

[0042] As explained above, by using the pressing device of the present invention, even novice DIY users can easily and reliably fix the necessary components to the building wall. The pressing device PRS described in the embodiment is sold together with, for example, the fixing pin PN, but it may also be sold in appropriate combination with the pull-out fitting RJ, shelf support member PL, and joint member JT. It should be noted that the shapes and dimensions of each component described in the embodiment are merely examples and can be changed as appropriate. [Explanation of Symbols]
