[0003] [Patent Document 1] Japanese Patent Publication No. 2022-146473 Summary of the Invention [Problem to be solved by the invention]

[0004] According to Patent Document 1, when the first area is a worker area where construction workers come and go and the second area is an area outside the first area, the bolt, which is the movable shaft, is attached to the fitting body in a vertical position. Furthermore, because the bolt head, which is the operation receiving portion, is exposed upward, construction workers can tighten the bolt more easily than when the bolt is attached to the fitting body in a horizontal position. More specifically, construction workers can reach out from the worker area to the external area and tighten the bolt by inserting an impact driver into the bolt head from above. However, with this configuration, it is difficult to visually check the tightening amount (insertion amount) of the bolt from above, making it difficult for construction workers to grasp the degree of attachment of the temporary handrail mounting bracket to the plate-like member.

[0005] An object of the present invention is to provide a handrail mounting hardware that makes it easy to check the mounting condition when mounting it on a plate-like member. [Means for solving the problem]

[0006] A handrail mounting hardware according to a first aspect of the present invention is a handrail mounting hardware for attaching a handrail to a plate-like member having a front surface, a back surface parallel to the front surface, and an upper surface continuous with the front surface and the back surface, and comprises a main body portion, a movable portion, an operating portion, and a support portion. The main body portion is defined by a first surface facing the front surface, a second surface facing the back surface, and a third surface facing the upper surface, and has a pair of side walls each formed with a notch that can be hooked onto the plate-like member, and defines a holding portion that holds the handrail so that the handrail stands upright relative to the upper surface. The movable portion is slidable between the pair of side walls, and has a clamping surface that faces the front surface and can clamp the plate-like member between itself and the second surface, and a pressure-receiving surface that does not face the front surface. The operating unit has a first end capable of receiving an operation from a user and a second end capable of contacting the pressure receiving surface, and presses the pressure receiving surface in response to the operation received by the first end to slide the movable unit. The support unit supports the operating unit between the pair of side wall units, and supports the operating unit so that an axis passing through the first end and the second end forms an angle greater than 0° and less than 90° with respect to an imaginary plane parallel to the second surface. [Effects of the Invention]

[0007] According to the present invention, a handrail mounting bracket for attaching a handrail to a plate-shaped member is provided, which makes it easy to grasp the installation condition when attaching the handrail mounting bracket itself to the plate-shaped member.

[0009] A handrail mounting hardware according to one embodiment of the present invention will be described below with reference to the drawings. For the sake of convenience, some components may be omitted from the drawings. Furthermore, the dimensions of the components shown in the drawings may not necessarily correspond to the actual dimensions of the components.

[0010] <1. Overview> FIG. 1 is a perspective view showing an example of use of a handrail mounting bracket 1 (hereinafter simply referred to as "bracket 1") according to one embodiment of the present invention. Bracket 1 is primarily used to install a temporary handrail 2 on stairs, landings, and the like installed at a construction site for a structure. Such stairs and landings are typically made of steel and are transported to the construction site and assembled. A plate-shaped member 3, also known as a "bow board," is installed on these stairs and landings, dividing a first space S1, such as the stairs or landing where people can pass through, from a second space S2, which is the space outside. Bracket 1 is attached to the top of this plate-shaped member 3 and holds the handrail 2 so that it stands upright from the top of the plate-shaped member 3. In this way, the handrail 2 is attached to the plate-shaped member 3 via bracket 1, and the handrail 2 also divides the first space S1 from the second space S2.

[0011] [Plate-shaped member] The plate-shaped member 3 has a front surface 30, a back surface 31, and an upper surface 32. In this embodiment, the front surface 30 is a surface facing the second space S2. In this embodiment, the back surface 31 is a surface facing the first space S1 and is parallel to the front surface 30. The upper surface 32 is a surface that is continuous with the front surface 30 and the back surface 31 and faces upward. In this embodiment, the upper surface 32 is perpendicular to the front surface 30 and the back surface 31. Hereinafter, the direction perpendicular to the upper surface 32 is defined as the up-down direction. The plate-shaped member 3 is preferably made of metal. The thickness of the plate-shaped member 3 is about 7 mm to 28 mm, although it is not limited thereto.

[0012] [handrail] FIG. 2 is a perspective view showing an example configuration of a handrail 2 according to this embodiment. As shown in FIG. 2, the handrail 2 includes support pillars 20a-c and a frame 21 connected to the support pillars 20a-c. The support pillars 20a-c and the frame 21 are preferably, but not limited to, made of metal pipes with a circular cross section. The support pillars 20a-c are each members that extend in one direction and have lower end portions 200a-c. The lower end portions 200a-c are each inserted into a holding portion 100 of the metal fitting 1, which will be described later, and hold the handrail 2 so that it stands upright perpendicular to the upper surface 32. The lower end portions 200a-c may be welded to the inner wall of the holding portion 100 as necessary, or may be fixed to the inner wall of the holding portion 100 with concrete.

[0013] The frame portion 21 is substantially rectangular and includes horizontal bars 210a and 210b, vertical bars 211a and 211b, and corner portions 212a-d. When the handrail 2 is attached to the plate-shaped member 3 with the metal fittings 1, the horizontal bars 210a and 210b extend in the left-right direction, and the vertical bars 211a and 211b extend in the up-down direction. At least one of the horizontal bars 210a and 210b and the vertical bars 211a and 211b may be configured to be expandable and contractible in the direction of extension. The corner portions 212a-d connect the horizontal bar 210a and the vertical bar 211a, the horizontal bar 210a and the vertical bar 211b, the horizontal bar 210b and the vertical bar 211b, and the horizontal bar 210b and the vertical bar 211a, respectively, to form substantially rectangular corners.

[0014] <2.Handrail mounting hardware> The following description of the fitting 1 will be based on the directions defined in Fig. 1. Fig. 3 is a top view of the fitting 1, Figs. 4A and 4B are left and right side views of the fitting 1, and Fig. 5 is a VV cross-sectional view of Fig. 3. The fitting 1 comprises a main body 10, a movable part 11, an operating part 12, and a support part 13. In this embodiment, each part is made of metal.

[0015] [Main body] The main body 10 has a pair of side walls 101a, 101b that form the sides of the metal fitting 1, and a side wall 101c that is continuous between the pair of side walls 101a, 101b. In this embodiment, these are integrally formed and form a roughly U-shape when viewed from above. The side walls 101a-101c define a holding section 100, which is a space into which the lower ends 200a-c of the handrail 2 are inserted and which holds them. Note that the holding section 100 according to this embodiment is closed off when viewed from above by a partition wall 130 of the support section 13, which will be described later.

[0016] The side walls 101a and 101b are formed with cutouts 1010a and 1010b, respectively. The cutouts 1010a and 1010b are portions that can be hooked onto the plate-like member 3 when attaching the fitting 1 to the plate-like member 3. When the cutout 1010a is hooked onto the plate-like member 3, the cutout 1010a is defined by a first surface 1011a that faces the front surface 30, a second surface 1012a that faces the back surface 31, and a third surface 1013a that faces the top surface 32. In other words, the thickness of the material that constitutes the side wall 101a is the width of the first surface 1011a to the third surface 1013a. Similarly, when the notch portion 1010b is hooked onto the plate-shaped member 3, it is defined by a first surface 1011b facing the front surface 30, a second surface 1012b facing the back surface 31, and a third surface 1013b facing the top surface 32. In other words, the thickness of the member constituting the side wall portion 101b is the width of the first surface 1011b to the third surface 1013b. In this embodiment, the first surface 1011a and the second surface 1012a, and the first surface 1011b and the second surface 1012b are parallel to each other, the third surface 1013a is perpendicular to the first surface 1011a and the second surface 1012a, and the third surface 1013b is perpendicular to the first surface 1011b and the second surface 1012b.

[0017] When the metal fitting 1 is properly attached to the plate-shaped member 3 and fixed so as not to move, the second surfaces 1012a and 1012b each contact the back surface 31, and the third surfaces 1013a and 1013b each contact the top surface 32. Here, the distance between the first surface 1011a and the second surface 1012a and the distance between the first surface 1011b and the second surface 1012b are configured to be slightly larger than the expected maximum thickness of the plate-shaped member 3. Therefore, a movable part 11, which will be described later, is provided to correspond to the thickness of the plate-shaped member 3 and to reliably sandwich the plate-shaped member 3 between the second surfaces 1012a and 1012b.

[0018] A cylindrical support 102 is formed between the side walls 101a and 101b to connect them. The support 102 extends in the left-right direction and is formed on the opposite side of the holding part 100 with the notches 1010a and 1010b as reference points. The support 102 supports the movable part 11, which will be described later, so that the movable part 11 can slide.

[0019] [Movable part] The movable part 11 is installed between a pair of side wall portions 101a, 101b. The movable part 11 according to this embodiment is configured as a block-shaped member and has a clamping surface 110 that can clamp a plate-shaped member 3 between the first surface 1011a, 1101b and the second surface 1012a, 1012b. The clamping surface 110 is configured to be parallel to the first surface 1011a, 1101b and the second surface 1012a, 1012b, and faces the front surface 30 when the bracket 1 is hooked onto the plate-shaped member 3. Note that the clamping surface 110 does not have to be strictly parallel to the first surface 1011a, 1101b and the second surface 1012a, 1012b. The movable part 11 has a guide hole 112 that penetrates the movable part 11 in the left-right direction and is oblong in side view. The support part 102 is inserted into the guide hole 112. The support part 102 is movable within the guide hole 112 in a region from one end to the other end in the longitudinal direction of the guide hole 112. This allows the movable part 11 to slide relative to the main body part 10 without being completely separated from the main body part 10. The longitudinal direction of the guide hole 112 is parallel to the axis A1 of the operation part 12, which will be described later. Therefore, the direction of sliding movement of the movable part 11 is parallel to the axis A1.

[0020] The movable part 11 further has a bottom surface 113. The bottom surface 113 is a surface that extends from below the clamping surface 110 so as to move away from the clamping surface 110 as it goes upward, and is parallel to the axis A1 in a side view. The bottom surface 113 is configured to be in contact with a lower wall 133 of the support part 13, which will be described later, and to be slidable on the lower wall 133. In other words, the lower wall 133 restricts the rotational movement of the movable part 11 about the support part 102, and assists the sliding movement in a direction parallel to the axis A1.

[0021] The movable part 11 further has a pressure receiving surface 111. The pressure receiving surface 111 is a surface extending from above the clamping surface 110 so as to move away from the clamping surface 110 as it extends downward. When the metal fitting 1 is hooked onto the plate-shaped member 3, the pressure receiving surface 111 faces forward and upward and does not face the front surface 30. The pressure receiving surface 111 contacts a second end 122 of the operating part 12, which will be described later, and receives a pressing force from the operating part 12. In this embodiment, the pressure receiving surface 111 is configured to be perpendicular to the axis A1 so as to reliably receive a pressing force along the axis A1 from the second end 122. When the pressure receiving surface 111 receives a pressing force from the second end 122, the movable part 11 slides in a direction parallel to the axis A1. In response to this, the clamping surface 110, while facing the front surface 30, moves from front to rear until it contacts the front surface 30.

[0022] [Operation section] The operating unit 12 receives an operation from the user at the fitting 1 and transmits the operation to the movable unit 11. The operating unit 12 has a first end 121 that can receive an operation from the user, a second end 122 that can contact the pressure-receiving surface 111, and an intermediate portion 120 that extends between the first end 121 and the second end 122. The operating unit 12 according to this embodiment is configured as a hexagonal bolt, with the first end 121 being the head of the hexagonal bolt and the second end 122 being the tip of the threaded portion. The intermediate portion 120 is formed with a thread that engages with a female thread portion 134 of the support unit 13, which will be described later. The first end 121 is located on the opposite side of the fitting 1 from the holding unit 100 with respect to the cutout portions 1010a and 1010b, and is supported by the support unit 13 so that its main surface faces forward and upward. The main surface refers to the surface of the first end 121 that has the largest area. The first end 121 receives a rotation operation in the second space S2 from a user in the first space S1 via a tool such as an impact driver.

[0023] When the first end 121 is rotated in the direction to tighten the screw by the user's operation, the entire operation unit 12 advances in the direction of screw advancement due to the screw mechanism between the intermediate portion 120 and the female thread portion 134, and the second end 122 contacts and presses the pressure receiving surface 111. Furthermore, when the first end 121 is rotated in the direction to loosen the screw by the user's operation, the entire operation unit 12 retreats in the direction opposite to the direction of screw advancement due to the screw mechanism between the intermediate portion 120 and the female thread portion 134, and the second end 122 moves away from the pressure receiving surface 111. This relieves the pressing force on the pressure receiving surface 111, and the plate-like member 3 is released from clamping by the clamping surface 110 and the second surface 1012a and the second surface 1012b. In this way, the operation unit 12 advances and retreats relative to the main body 10 along the axis A1 direction passing through the center of the first end 121 and the center of the second end 122.

[0024] [Support part] The support portion 13 is disposed between and connected to the pair of side walls 101a, 101b to support the operation unit 12 in a predetermined position between the pair of side walls 101a, 101b. The support portion 13 according to this embodiment is composed of a plate-like member bent at multiple locations and forms at least a partition wall 130, an operation wall 131, and a lower wall 133. The partition wall 130 extends vertically above the cutouts 1010a, 1010b to close the holding portion 100. The lower wall 133 extends from the lower ends of the first surfaces 1011a, 1011b so as to become increasingly farther away from the first surfaces 1011a, 1011b as it extends upward. The lower wall 133 according to this embodiment is parallel to the axis A1 in a side view and is in contact with the bottom surface 113 of the movable portion 11 so as to be relatively movably movable therewith, thereby assisting the sliding movement of the movable portion 11.

[0025] The operation wall 131 separates the external space and the internal space of the fitting 1, exposing the first end 121 of the operation unit 12 to the external space of the fitting 1 and accommodating the second end 122 in the internal space of the fitting 1. An internally threaded portion 134 is connected to the side of the operation wall 131 facing the internal space of the fitting 1. The internally threaded portion 134 is a substantially cylindrical member, and a thread groove that engages with the threads of the intermediate portion 120 of the operation unit 12 is formed on the inner wall thereof. A through hole 1310 that connects to the internally threaded portion 134 is formed in the operation wall 131, and the intermediate portion 120 of the operation unit 12 passes through both the internally threaded portion 134 and the through hole 1310. Note that the inner diameter of the through hole 1310 is smaller than the outer diameter of the first end 121, so the first end 121 cannot pass through the through hole 1310 and protrudes above the operation wall 131. When the operation unit 12 penetrates the female thread portion 134, the female thread portion 134 supports the operation unit 12 so that its axis A1 forms an angle greater than 0° and less than 90° with respect to a plane extending in the up-down direction and the left-right direction. The up-down direction here refers to a direction perpendicular to the top surface 32 of the plate-like member 3. The angle is an angle in the counterclockwise direction in FIG. 5 around the second end portion 122. That is, the female thread portion 134 supports the operation unit 12 so that the axis A1 forms an acute angle with respect to an imaginary plane P that is parallel to the second surfaces 1012a and 1012b. In this embodiment, the angle is 45°, but is not limited to this as long as it is greater than 0° and less than 90°.

[0026] <3. How to use the metal fittings> 6A and 6B, a method for using the fitting 1 will be described. Note that although the handrail 2 is not shown in Figures 6A and 6B, the handrail 2 may be attached to the fitting 1 either before or after the fitting 1 is attached to the plate-like member 3.

[0027] First, confirm that the screw mechanism between the operating portion 12 and the female thread portion 134 of the fitting 1 is sufficiently loosened. In this state, as shown in FIG. 6A , the first end portion 121 and a portion of the middle portion 120 protrude forward and upward from the operating wall 131. Furthermore, the movable portion 11 is not visible from the outside of the fitting 1 in a side view, or even if it is visible, it is in a state where it can be easily accommodated in its entirety within the internal space of the fitting 1. When the movable portion 11 is entirely accommodated within the internal space of the fitting 1, the clamping surface 110 is located farther from the second surface 1012a and the second surface 1012b than the first surface 1011a of the cutout portion 1010a and the first surface 1011b of the cutout portion 1010b.

[0028] Next, the metal fitting 1 is hooked onto the desired position of the plate-shaped member 3. Specifically, the metal fitting 1 is hooked onto the plate-shaped member 3 in such a manner that the first surfaces 1011a and 1011b face the front surface 30, the second surfaces 1012a and 1012b face the back surface 31, and the third surfaces 1013a and 1013b face the top surface 32. Because the distance between the first surface 1011a and the second surface 1012a and the distance between the first surface 1011b and the second surface 1012b are greater than the thickness of the plate-shaped member 3, the metal fitting 1 is movable relative to the plate-shaped member 3 in this state.

[0029] Next, the first end 121 is rotated in the direction that tightens the screw, and the operating part 12 advances into the internal space of the metal fitting 1. As a result, the second end 122 presses the pressure-receiving surface 111 of the movable part 11, and the clamping surface 110 slides in a direction parallel to the axis A1. However, because the clamping surface 110 is parallel or approximately parallel to the first surfaces 1011a and 1011b, the clamping surface 110 seen through the cutout portion 1010a or the cutout portion 1010b appears as if it is moving from the first surfaces 1011a and 1011b toward the second surfaces 1012a and 1012b.

[0030] When the clamping surface 110 comes into contact with the front surface 30, the second surfaces 1012a and 1012b come into contact with the back surface 31 by tightening the screws of the operating unit 12, and it is confirmed that the plate-shaped member 3 is securely clamped between the clamping surface 110 and the second surfaces 1012a and 1012b, the attachment of the metal fitting 1 to the plate-shaped member 3 is complete. Note that the state in which the plate-shaped member 3 is securely clamped refers to a state in which the main body 10 does not move or rotate relative to the plate-shaped member 3, even if the handrail 2 is attached to the main body 10.

[0031] <4. Features> The metal fitting 1 according to the above embodiment provides the following effects.

[0032] (1) The distance between the clamping surface 110 and the second surfaces 1012a and 1012b of the fitting 1 can be adjusted appropriately depending on the thickness of the plate-shaped member 3. Therefore, the fitting 1 can accommodate plate-shaped members 3 having a thickness within a certain range. Here, the distance between the clamping surface 110 and the second surfaces 1012a and 1012b may be difficult for a user working in the first space S1 to visually recognize due to its positional relationship with the plate-shaped member 3. In this regard, in the fitting 1, as described above, the operating unit 12 is supported by the support portion 13 in an orientation in which the axis A1 forms an acute angle with respect to the imaginary plane P parallel to the second surfaces 1012a and 1012b. The first end 121 and its vicinity are exposed on the operation wall 131. Therefore, a user viewing the fitting 1 from above can visually recognize not only the main surface of the first end 121 exposed on the operation wall 131, but also other surfaces thereof and the intermediate portion 120. In particular, the length of intermediate portion 120 visible on operation wall 131 projected onto a plane parallel to top surface 32 coincides with the amount of movement of clamping surface 110 in the front-to-rear direction. This allows the user to grasp the position of clamping surface 110 while operating operation unit 12, even if they cannot directly see clamping surface 110 and its vicinity. In other words, they can easily grasp the state of attachment of metal fitting 1 to plate-like member 3.

[0033] (2) Furthermore, when attaching the metal fitting 1 to the plate-shaped member 3 with the handrail 2 held by the holding part 100, if the operating part 12 is supported in a position where the axis A1 is parallel to the imaginary plane P (i.e., parallel to the direction in which the handrail 2 stands), a tool such as an impact driver may interfere with the handrail 2 when operating the first end 121, hindering the work. In this regard, the metal fitting 1 is supported so that the axis A1 of the operating part 12 forms an angle with the imaginary plane P that is greater than 0° and less than 90°, and the first end 121 is positioned farther from the handrail 2 in the front-to-rear direction than the second end 122. As a result, a tool such as an impact driver is applied to the first end 121 in a position where it moves further away from the handrail 2 as it goes upward, making it less likely to interfere with the handrail 2 and improving workability.

[0034] (3) The movable part 11 having the clamping surface 110 slides in the direction of the pressing force transmitted by the operating part 12. Therefore, the fitting 1 does not require a component to convert the pressing force of the operating part 12 into a pressing force in a different direction and then operate the clamping surface 110, and can be constructed with fewer parts. This reduces the manufacturing cost of the fitting 1 and makes it easier to replace the fitting 1.

[0035] (4) The movable part 11 receives a force from the operating part 12 at the pressure receiving surface 111 in a rotational direction around the support part 102. This rotational direction is a direction in which the clamping surface 110 faces downward, so the contact between the clamping surface 110 and the front surface 30 can be linear. This allows the metal fitting 1 to be more firmly engaged with the plate-shaped member 3, making it less likely for displacement to occur.

[0036] <5. Variations> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

[0037] (1) The configuration of the handrail 2 to which the fitting 1 is applied is not limited to the above-described embodiment and can be modified as appropriate. Therefore, the configuration of the retaining portion 100 of the fitting 1 can also be modified as appropriate to match the handrail 2. For example, the handrail 2 does not need to include pipe-shaped support portions 20a-c, and the horizontal beam portion 210b of the frame portion 21 can be configured so that it is held by the retaining portion 100. In other words, instead of the space shown in FIG. 3 , the retaining portion 100 can be configured as, for example, arc-shaped recesses formed at the upper ends of a pair of sidewall portions 101a, 101b. The arc-shaped recesses each receive a portion of the pipe-shaped handrail 2 extending in the left-right direction and are welded to the recesses to raise the handrail 2. Furthermore, the retaining portion 100 does not need to be positioned on the opposite side of the first end 121 relative to the cutouts 1010a and 1010b. For example, it can be positioned above the cutouts 1010a and 1010b.

[0038] (2) The operating unit 12 is not limited to being formed by a hexagonal bolt and can be modified as appropriate. The operating unit 12 may be formed by a screw having a threaded head, such as a socket head bolt.

[0039] (3) The configuration of the movable part 11 is not limited to that of the above embodiment. For example, the pressure-receiving surface 111 does not have to be perpendicular to the axis A1, as long as it can receive the pressure from the operating part 12. Furthermore, the movable part 11 may be supported not by the support part 102 but by guide rails or the like formed on the inner walls of the pair of side wall parts 101 a, 101 b.

[0040] (4) The configuration of the notch portions 1010a and 1010b is not limited to that of the above embodiment. For example, the first surfaces 1011a and 1011b do not have to be longer than the second surfaces 1012a and 1012b in the vertical direction, but may be the same length as or shorter than the second surfaces 1012a and 1012b.
