Hereinafter, the present disclosure will be described in more detail with reference to the drawings.

FIG. 1A is a plan view showing a handrail structure 100 according to a first embodiment of the present disclosure. The wall W to which the handrail structure 100 is attached is, for example, a wall provided in a two-story industrialized house having a steel frame.

Note that in the specification, claims, and drawings of this application, the term "spacer" refers to a spacer that connects a handrail bar fixing portion 11 and a handrail bar 20 in a bracket 10, which will be described later, in the axial direction of the handrail bar 20 (direction along the central axis O). This is a general term for the parts that are separated from each other.

The wall W to which the handrail structure 100 is fixed is assumed to be a wall extending in the vertical direction in a building, and the direction perpendicular to the paper surface in FIG. 1A is the vertical direction. Further, the left-right direction in FIG. 1A is the left-right direction (longitudinal direction) of the handrail structure 100, and the up-down direction in FIG. 1A is the front-back direction of the handrail structure 100. However, the location (fixed portion) to which the handrail structure 100 is fixed is not limited to this, and may be fixed to the upper part of the waist wall, the ceiling, or the floor of the building. The radially outer side of the handrail bar 20 is the direction away from the central axis O along a straight line that passes through the central axis O of the handrail bar 20 in FIG. It means the direction along the central axis O.

As shown in FIG. 1A, the handrail structure 100 according to the present embodiment fixes the handrail bar 20 on which the user puts his/her hand, the edge surfaces 20a (see FIG. 2) at both longitudinal ends of the handrail bar 20, and It includes a bracket 10 fixed to a wall W (fixed part).

In this embodiment, the handrail bar 20 is a rod-shaped member having a substantially cylindrical shape, and the left-right direction in FIG. 1A is the longitudinal direction of the handrail bar 20. At one location in the circumferential direction at the longitudinal end of the handrail bar 20, there is a notch 24 that suppresses rotation of the handrail bar 20 around the central axis O by inserting a rotation stopper 18 provided on the bracket 10. (See FIGS. 1B and 2). The bottom of the notch 24 is inclined with respect to the central axis O. In the illustrated example, the bottom of the notch 24 is inclined radially outward at about 45 degrees from the small end surface 20a toward the longitudinal center of the handrail bar 20.

A prepared hole 22 is provided in the radial center of the small end face 20a of the handrail bar 20, which is used when fixing the handrail bar 20 to the handrail fixing portion 11 of the bracket 10 with a countersunk wood screw 30 (shaft-shaped member). . Although the length of the pilot hole 22 is shown to be longer than the length of the countersunk wood screw 30 in FIG. 1A, the length of the pilot hole 22 is shorter than the length of the countersunk wood screw 30. It's okay.

As the material of the handrail bar 20, for example, poplar LVL (Laminated Veneer Lumber) can be used. However, the present invention is not limited to this embodiment, and the handrail bar 20 may be formed using other materials such as other wood, metal, and synthetic resin.

The bracket 10 includes a base 15 to be fixed to a wall W of a building, a handrail fixing part 11 vertically erected from the base 15 to the wall W, an upper wall 13, a lower wall (not shown), and a handrail fixing part 11, an upper wall 13, and a lower wall (not shown). A front wall 14 that closes the end of the portion 11 on the side opposite to the base 15 (on the user side), and a front wall 14 that protrudes from the handrail fixing portion 11 toward the handrail 20 side and radially extends the longitudinal end of the handrail 20. A cylindrical wall part 16 that surrounds the handrail bar 20 from the outside and prevents it from falling off, and a projection part 12 (spacer) that is integrally provided on the handrail fixing part 11 and that the end face 20a of the handrail bar 20 comes into contact with (FIG. 2) ) and a rotation stopper 18 that protrudes from the handrail fixing part 11 toward the handrail 20 and enters the above-mentioned notch 24 to suppress rotation of the handrail 20 around the central axis O. The bracket 10 is open on the right side in FIG. 1A, and the person installing the handrail structure 100 can access the countersunk wood screw 30 from the open side. Note that after the handrail structure 100 is fixed to the wall W, the open portion of the bracket 10 can be closed with a decorative board or the like. In this embodiment, the base portion 15, the handrail fixing portion 11, the projection portion 12, the upper wall 13, the lower wall, the front wall 14, the cylindrical wall portion 16, and the rotation stopper 18 are integrally formed by zinc die casting. Note that metal materials other than zinc may be used, and the bracket 10 may be constructed by assembling a plurality of members.

The base 15 can be provided with a mounting hole (not shown), for example, and can be screwed and fixed to the wall W using a wood screw and the mounting hole. However, the embodiment is not limited to this embodiment, and the base 15 can also be fixed to the wall W by other means such as engagement, adhesion, etc.

As shown in FIG. 2, the protruding portion 12 is a portion that is integrally formed on the handrail bar fixing portion 11 and protrudes toward the handrail bar 20 side. The protrusion 12 protrudes in a substantially dome shape, and a countersunk wood screw 30 is passed through the radial center position (on the central axis O) of the protrusion 12 to fix the handrail bar fixing part 11 and the handrail bar 20. A mounting hole 12a is provided for the purpose. That is, the countersunk screw 30 is configured to penetrate through the protrusion 12 which is a spacer. As shown in FIG. 2, the protrusion 12 is a part that separates the handrail fixing part 11 and the handrail 20 in the bracket 10 in the direction along the central axis O of the handrail 20, and is referred to as a "spacer" in this embodiment. plays the role of

The countersunk wood screw 30 is a wood screw whose head 31 has a dish-shaped shape, and as shown in FIG. The handrail bar fixing portion 11 and the handrail bar 20 are fastened together.

In this embodiment, the outer diameter of the protrusion 12 is smaller than the outer diameter of the handrail bar 20. Therefore, a space is formed in a region between the fore-end surface 20a and the handrail bar fixing portion 11, which is radially outward of the protrusion 12 and radially inward from the outer peripheral end of the fore-face surface 20a. As a result, the radially outer region of the protrusion 12 forms a gap between the handrail bar fixing part 11 and the handrail bar 20, and the outer peripheral part of the small end surface 20a of the handrail bar 20 forms a gap between the handrail bar fixing part 11 and the handrail bar 20. 11, the protrusion 12 can be tilted as a fulcrum in the vicinity of the central axis O where the countersunk screw 30 is disposed. Therefore, even if a bending load is applied to the longitudinal center portion of the handrail 20 due to the user grasping the handrail 20, the small end surface 20a of the handrail 20 will be moved around the protrusion 12 near the countersunk wood screw 30 as a fulcrum. Since it is tilted, it is possible to suppress the application of a pulling force to the countersunk screw 30.

In this embodiment, the inner diameter of the attachment hole 12 a provided in the protrusion 12 is slightly larger than the outer diameter of the threaded portion 33 of the countersunk screw 30 . With this configuration, when the edge surface 20a of the handrail bar 20 is tilted on the protrusion 12, it is possible to prevent the countersunk wood screw 30 from coming into contact with the mounting hole 12a and obstructing the inclination of the edge surface 20a.

As shown in FIGS. 1B and 2, the rotation stopper 18 is provided so as to diagonally span the handrail bar fixing part 11 and the cylindrical wall part 16 at a circumferential position corresponding to the notch part 24, The width in the direction perpendicular to the plane of the paper in FIG. 2 is slightly narrower than the width of the notch 24 in the same direction. With such a configuration, even if the handrail bar 20 is attempted to rotate around the central axis O, the side surface 18a of the rotation stopper 18 comes into contact with the side surface 24a of the notch 24, suppressing further rotation of the handrail bar 20 ( (See Figure 1B, etc.). This effectively prevents the handrail bar 20 from rotating around the central axis O with respect to the bracket 10 even when the small end surface 20a of the handrail bar 20 is fixed to the bracket 10 at only one point on the central axis O. Can be suppressed. In this case, the rotation stopper 18 can be integrally formed on the bracket 10 side, and the notch 24 can be formed on the handrail bar 20 side by slight post-processing, so that the central axis O of the handrail bar 20 can be formed by simple means. Rotation of the surroundings can be suppressed.

In this embodiment, the rotation stopper 18 is inserted into the cutout portion 24 to suppress rotation of the handrail bar 20 about the central axis O, but the present invention is not limited to this embodiment. For example, as in the first modification shown in FIG. 3A, the countersunk screw 30 (threaded portion 33) is offset forward (upward in the figure) with respect to the central axis O, and in the vertical direction (in the figure) perpendicular to the offset direction. The radial gap between the handrail bar 20 and the cylindrical wall portion 16 in the left-right direction) may be configured to be small. By employing such a configuration, when a rotational moment is applied to the handrail bar 20 and the handrail bar 20 attempts to rotate around the countersunk wood screw 30 and the protrusion 12, the outer circumferential surface of the handrail bar 20 is disposed close to each other in the vertical direction. The handrail bar 20 is prevented from rotating any further by coming into contact with the cylindrical wall portion 16 that has been rotated. In this case, the cylindrical wall portion 16 provided on the bracket 10 will serve as a rotation stopper.

Further, as in the second modification shown in FIG. 3B, the tip of the screw 35 screwed into the handrail fixing part 11 by the female thread part 19 is inserted into the bottomed hole provided on the small end surface 20a of the handrail bar 20. 26 may be entered. With such a configuration, when the handrail bar 20 attempts to rotate around the central axis O, the outer surface of the tip of the screw 35 integrated with the handrail bar fixing part 11 comes into contact with the inner surface of the bottomed hole 26, and the handrail bar is rotated. It acts to suppress the rotation of 20. Note that instead of screwing the screw 35 into the handrail bar fixing part 11, a convex part protruding from the handrail bar fixing part 11 toward the handrail bar 20 may be configured to fit into the bottomed hole 26.

Further, as in the third modification shown in FIG. 3C, the screw 35 passes through the through hole 19a provided in the handrail bar fixing part 11 and protrudes toward the handrail bar 20 side, so that the head of the screw 35 passes through the through hole 19a provided in the handrail bar fixing part 11. The tip of the screw 35 may be threadedly engaged with the end face 20a of the handrail bar 20 in a floating state. With such a configuration, when the handrail bar 20 attempts to rotate around the central axis O, the outer surface of the threaded portion of the screw 35 integrated with the handrail bar 20 comes into contact with the inner surface of the through hole 19a, thereby preventing the handrail bar 20 from rotating. It acts to suppress.

As described above, the present embodiment is a handrail structure 100 that includes a handrail bar 20 and a bracket 10 that fixes both ends of the handrail bar 20 and is fixed to a fixed part (wall W) of a building. The edge surface 20a of the handrail bar 20 is fixed to the handrail bar fixing part 11 in 10 with a shaft member (countersunk wood screw 30) via a spacer, and the area between the edge face 20a and the handrail bar fixing part 11 is A space is formed in a radially outer region of the spacer. By employing such a configuration, the radially outer region of the spacer forms a gap between the handrail bar fixing part 11 and the handrail bar 20, so that the outer peripheral part of the small end surface 20a of the handrail bar 20 is fixed to the handrail bar. The edge surface 20a can be tilted with respect to the handrail fixing part 11 without coming into contact with the part 11. Therefore, even if a bending load is applied to the longitudinal center portion of the handrail 20 due to the user grasping the handrail 20, the handrail will not move when the end surface 20a of the handrail 20 is tilted with respect to the handrail fixing portion 11. The load that presses the rod fixing part 11 can be reduced. Therefore, the pulling force applied to the shaft-like member can be reduced.

Moreover, in this embodiment, the spacer is configured to be a protrusion 12 provided in the handrail bar fixing part 11 so as to protrude toward the handrail bar 20 side. By employing such a configuration, the spacer can be easily integrated with the handrail bar fixing portion 11, and the number of parts and manufacturing steps can be reduced.

Further, in this embodiment, the handrail bar fixing portion 11 is configured such that the end surface 20a of the handrail bar 20 is fixed to the handrail bar fixing portion 11 by one shaft-shaped member. By employing such a configuration, even if a load is applied in the bending direction to the longitudinal center portion of the handrail bar 20, the end face 20a of the handrail bar 20 tilts around the spacer near the one shaft-shaped member as a fulcrum. It is possible to suppress the application of a pulling force to the one shaft-like member.

Moreover, in this embodiment, the bracket 10 is configured to have a rotation stopper 18 that suppresses rotation of the handrail bar 20 around the axis (around the central axis O). By adopting such a configuration, even when the end face 20a of the handrail bar 20 is fixed by one shaft-shaped member, rotation of the handrail bar 20 around the axis is suppressed, and the long-term durability of the handrail bar 20 is further improved. can be improved.

Next, a handrail structure 200 according to a second embodiment of the present disclosure will be described using FIG. 4 and the like. FIG. 4 is a drawing corresponding to FIG. 2 in the first embodiment, and is an enlarged view of the pan-head wood screw 130 portion in the handrail structure 200.

Note that, compared to the first embodiment, this embodiment has a configuration similar to that of the first embodiment except that a spacer 112 is provided instead of the protrusion 12. Therefore, the explanation will focus on the differences from the first embodiment.

As shown in FIG. 4, the handrail structure 200 according to the present embodiment fixes the handrail bar 20 on which the user puts his hand, and the edge surfaces 20a at both longitudinal ends of the handrail bar 20, and also fixes the handrail bar 20 on which the user puts his/her hand. ).

The bracket 110 includes a handrail fixing part 111 as in the first embodiment, and a spacer 112 is arranged between the handrail fixing part 111 and the edge surface 20a of the handrail 20. As shown in FIG. 4, the spacer 112 has a smaller diameter than the handrail bar 20, and is a member that separates the handrail fixing part 111 of the bracket 110 from the handrail bar 20 in the direction along the central axis O of the handrail bar 20.

The pan-head wood screw 130 is a wood screw whose head 131 has a pan-shaped shape. As shown in FIG. 4, the screw portion 133 of the pan-head wood screw 130 is engaged with the handrail bar 20 through the through hole 111a and the attachment hole 112a, and the head 131 is brought into contact with the handrail bar fixing portion 111. and the handrail bar 20 are fastened together.

The spacer 112 is a ring-shaped member, and a mounting hole 112a is provided in the radial center portion thereof for fixing the handrail bar fixing portion 111 and the handrail bar 20 by passing a pan-head wood screw 130 therethrough. In this embodiment as well, the inner diameter of the attachment hole 112a is formed slightly larger than the outer diameter of the threaded portion 133 of the pan-head wood screw 130. As the material of the spacer 112, for example, a rubber material such as hard rubber, synthetic resin, metal, etc. can be used.

The outer diameter of the spacer 112 is smaller than the outer diameter of the handrail bar 20, as shown in FIG. With this configuration, the radially outer region of the spacer 112 forms a gap between the handrail bar fixing part 111 and the handrail bar 20, and the outer peripheral part of the small end surface 20a of the handrail bar 20 forms a gap between the handrail bar fixing part 111 and the handrail bar 20. It can be tilted around the spacer 112 near the pan-head wood screw 130 as a fulcrum without coming into contact with the fixing part 111. Therefore, even if a bending load is applied to the longitudinal center portion of the handrail 20 due to the user grasping the handrail 20, the end surface 20a of the handrail 20 will not move along the center axis O where the pan-head wood screw 130 is arranged. Since it is tilted using the nearby spacer 112 as a fulcrum, it is possible to suppress the application of a pulling force to the pan-head wood screw 130.

As shown in FIG. 4, the outer diameter of the spacer 112 is smaller than the outer diameter of the handrail bar 20, so that a space is formed in a region that is radially outer of the spacer 112 and radially inner than the outer peripheral end of the small opening surface 20a. Although it is preferable to do so, it is not limited to this embodiment. The outer diameter of the spacer 112 may be the same as the outer diameter of the handrail bar 20 or may be larger than the outer diameter of the handrail bar 20. However, in this case, the spacer 112 needs to have smaller compression rigidity in the direction of the central axis O than the handrail bar 20.

When the outer diameter of the spacer 112 is the same as the outer diameter of the handrail bar 20, when a load in the bending direction is applied to the longitudinal center of the handrail bar 20, the small end surface 20a of the handrail bar 20 tilts, and the handrail in the direction of the load is The outer periphery of the end face 20a of the rod 20 approaches the handrail rod fixing part 111. Therefore, since the spacer 112 is compressed in the direction of the central axis O at the outer peripheral portion of the edge face 20a, a pull-out load corresponding to the compressive load acts on the pan-head wood screw 130. However, the compressive load becomes smaller as the compressive rigidity of the spacer 112 in the direction of the central axis O becomes smaller. Therefore, by selecting a material for the spacer 112 that has lower compressive rigidity in the central axis O direction than the handrail bar 20, it is possible to reduce the pullout load applied to the pan-head wood screw 130 due to the bending deformation of the handrail bar 20. can.

Note that whether or not the spacer 112 has smaller compressive rigidity in the direction of the central axis O than the handrail bar 20 can be measured by the measuring means shown in FIG.

The compression rigidity was measured by arranging the handrail bar 20 and the spacer 112, which are not fixed to each other, in series in the longitudinal direction of the handrail bar 20 in the same way as the handrail structure 200, and instead of the bracket 110 having high rigidity. Press against the installed test wall TW in the direction of the arrow with a predetermined load. FIG. 5 shows the case where the handrail bar 20 and the spacer 112 both have the same diameter D. Considering the case where the length T of the handrail bar 20 in the axial direction (along the central axis O) changes to T' and the length S of the spacer 112 in the axial direction changes to S' when pressed, the spacer 112 In order for it to be said that the compression rigidity is smaller than that of the handrail bar 20, the following formula (1) should be satisfied.

The left side of the above equation (1) is the compressive strain in the direction along the central axis O of the handrail bar 20, and the right side of the equation (1) is the compressive strain of the spacer 112. In order for the formula (1) to hold, for example, the materials of the spacer 112 and the handrail bar 20 must be selected so that the longitudinal elastic modulus of the spacer 112 in the direction of the central axis O is smaller than the longitudinal elastic modulus of the handrail bar 20. Bye. Moreover, the compressive deformation when pressed with a predetermined load does not necessarily have to be reversible elastic deformation. The spacer 112 may be compressively deformed with plastic deformation, such as a foamed member. In addition, the spacer 112 is made of a material such as a compression coil spring that is easily compressed and deformed in the direction of the central axis O, although the longitudinal elastic modulus of the material itself is not small, but the spacer 112 is configured so that its compression rigidity is small due to the shape of the spacer 112. It may be something.

As described above, the present embodiment is a handrail structure 200 that includes a handrail bar 20 and a bracket 110 that fixes both ends of the handrail bar 20 and is fixed to a fixed part (wall W) of a building. The small end face 20a of the handrail bar 20 is fixed to the handrail bar fixing part 111 in 110 with a shaft-like member (pan-head wood screw 130) via a spacer 112. The structure is such that the compression rigidity in the axial direction (direction along the central axis O) is small. By employing such a configuration, the spacer 112 is more easily compressively deformed in the direction along the center axis O than the handrail bar 20, so that the spacer 112 is moved in the direction of the center axis O due to the inclination of the end face 20a due to the deflection of the handrail bar 20. Compressed. Then, a pull-out load corresponding to the compressive load acts on the pan-head wood screw 130, but the compressive load becomes smaller as the compressive rigidity of the spacer 112 in the direction of the central axis O becomes smaller. Therefore, by selecting a material for the spacer 112 that has a lower compressive rigidity and is easier to compress and deform in the direction of the central axis O than the handrail bar 20, the pullout load applied to the pan-head wood screw 130 due to the bending deformation of the handrail bar 20 is reduced. can be reduced. This effect can be obtained even when the outer diameter of the spacer 112 is the same as or larger than the outer diameter of the handrail bar 20.

Further, in this embodiment, the spacer 112 is configured such that the longitudinal elastic modulus in the axial direction of the handrail bar 20 is smaller than that of the handrail bar 20. By employing such a configuration, the handrail structure 200 can be manufactured at low cost by employing a material that is easily compressible and deformable in mass production, such as an O-ring made of hard rubber, for the spacer 112.

Although the present disclosure has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various changes or modifications based on the present disclosure. It should therefore be noted that these variations or modifications are included within the scope of the present invention. For example, functions included in each component can be rearranged so as not to be logically contradictory, and a plurality of components can be combined into one or divided.

For example, in the first and second embodiments, the handrail bar 20 is attached to the brackets 10, 110 using one countersunk wood screw 30 or one pan-head wood screw 130, but the present invention is not limited to this embodiment. The handrail bar 20 may be attached to the brackets 10, 110 using two or more countersunk screws 30 or the like. For example, when using two countersunk screws 30, it is preferable to arrange the two countersunk screws 30 in a direction perpendicular to the direction in which the handrail bar 20 is most frequently loaded. Furthermore, the shaft-like member is not limited to the countersunk wood screw 30 and the pan-head wood screw 130, but other shaft-like members such as screws and bolts may be used.
