[0011] [First embodiment] A first embodiment of the present invention will now be described with reference to the drawings. 1 shows an entrance 1 of a building in which a handrail mounting structure 10 according to the first embodiment is configured, and a sliding door 2 is installed at the entrance 1. The sliding door 2 has three door bodies 4A, 4B, and 4C that are connected to the left and right and installed at the entrance 1 so as to be able to be opened and closed, and a handle 5 is attached to the door body 4A. In the following description, the left-right direction of the sliding door 2 is defined as the X-axis direction, the up-down direction of the sliding door 2 is defined as the Y-axis direction, and the front direction (out-of-plane direction) of the sliding door 2 is defined as the Z-axis direction. The X, Y, and Z axis directions are perpendicular to each other.

[0012] A frame 8 is installed on the visible surface of the frame portion 7 (column portion (base)) shown in FIG. 2 along the Y-axis direction that defines the entranceway 1 of the building skeleton 6. The frame 8 is disposed along the upper edge and the left and right vertical edges of the entranceway 1, respectively. In the first embodiment, as shown in FIG. 2 and FIG. 3, the frame 8 on the door end side is composed of an upper frame 81 and a lower frame 82 that are formed by being divided in the longitudinal direction. The upper frame 81 and the lower frame 82 have the same cross-sectional shape. The frame 8 may be made of wood, resin, etc., or may be made of other materials.

[0013] Between the upper frame 81 and the lower frame 82, a dividing section 83 is formed, which is a space in which the handrail 11 can be installed. The handrail 11 includes a base 20 that is screwed to the frame section 7 at the dividing section 83, brackets 30A and 30B that are fixed to the base 20, and a grip body 40 that is supported by the brackets 30A and 30B. The base 20 is formed to have the same cross-sectional shape as the upper frame 81 and the lower frame 82, is made of the same material as these, and constitutes a part of the frame 8. Bracket 30A is attached to one end 21 (upper end) in the Y-axis direction of base 20, and bracket 30B is attached to the other end 22 (lower end) in the Y-axis direction of base 20. As shown in Figs. 4 and 5, bracket 30A has a fixed portion 31 along the Z-axis direction and an arm portion 32 protruding from the end of fixed portion 31. Fixed portion 31 is formed in approximately the same shape as base 20 in a plan view as shown in Fig. 5. Bracket 30B is configured in the same manner as bracket 30A, and therefore the same reference numerals as those of each component of bracket 30A are appropriately used in the drawings, and detailed description thereof will be omitted. The grip 40 is formed to extend in the Y-axis direction, with its upper and lower ends fixed to the tips of the arm portions 32 of the brackets 30A and 30B.

[0014] The upper surface of the fixing portion 31 of the bracket 30A abuts against the lower surface of the upper frame 81, and the lower surface of the fixing portion 31 of the bracket 30B abuts against the upper surface of the lower frame 82. A projected surface 85 formed by the upper frame 81, the lower frame 82, the base 20, and the fixing portions 31 of the brackets 30A and 30B is flush with one another. Note that a step 86 to which the vertical frame 9, which is the fitting frame of the sliding door 2, is screwed is formed on one edge of the upper frame 81, the lower frame 82, and the base 20 along the Y-axis direction, and a step 33 having the same shape as the step 86 is also formed on the fixing portion 31.

[0015] In addition, the ends 21, 22 of the base 20 may be formed with a covering edge portion 23, for example, as in the modified example shown in FIG. 6. In this case, the fixing portion 31 of the brackets 30A, 30B has a dimension W2 in the X-axis direction that is smaller than the dimension W1 shown in FIG. 5, and is disposed between the covering edge portion 23 and the building frame 6. The covering edge portion 23 extends in the Z-axis direction and is disposed along the above-mentioned projection surface 85. The fixing portion 31 is disposed between the frame portion 7 and the covering edge portion 23, and is disposed so as to be covered by the covering edge portion 23 in appearance and not exposed. In addition, the covering edge portion 23 of the end portion 21 abuts against the upper frame 81, and the covering edge portion 23 of the end portion 22 abuts against the lower frame 82.

[0016] In the first embodiment, the frame 8 and the handrail 11 are installed as follows. First, the frame 8 is attached to the visible surface of the frame portion 7 of the building structure 6. The frame 8 on the door end side may be divided either before or after the building structure 6 is attached, and the frame 8 consisting of the upper frame 81 and the lower frame 82 may be prepared in advance. Then, the base 20 and the fixing portion 31 of the brackets 30A and 30B are arranged in the divided portion 83 between the upper frame 81 and the lower frame 82, and the base 20 is screwed to the frame portion 7. In the first embodiment, the screwing positions are at least two positions, one near the bracket 30A from the center in the Y-axis direction of the base 20 and the other near the bracket 30B, and three positions including the center position in the first embodiment. Since the handrail mounting structure 10 is constructed by installing the frame 8 and the handrail 11 in this manner, there is no need to go to the trouble of searching for a base for installing the handrail 11 in addition to the frame part 7 (base) for installing the frame 8, and there is also no need to go to the trouble of forming a new base for installing the handrail 11.

[0017] [Second embodiment] A second embodiment of the present invention will now be described with reference to the drawings. 7 and 8, the handrail mounting structure 10B according to the second embodiment is equipped with a handrail 11B instead of the handrail 11 described above, and the frame 8 on the door end side is not divided into an upper frame 81 and a lower frame 82 as in the first embodiment, but is composed of a single member along the Y-axis direction. Other than the above, the configuration of the handrail mounting structure 10B is the same as that of the handrail mounting structure 10.

[0018] The handrail 11B has brackets 50A, 50B having fixed parts 51 and arm parts 52, and a grip body 60 supported by brackets 50A, 50B. Fixed part 51 is aligned along the Z-axis direction, and arm parts 52 protrude from the ends of fixed part 51. Grip body 60 extends in the Y-axis direction, and both ends are fixed to the tips of arm parts 52. The frame 8 has grooves 87 formed along the Z-axis direction in which the fixing portions 51 of the brackets 50A and 50B are respectively disposed.

[0019] In the second embodiment, the frame 8 and the handrail 11B are installed as follows. First, the fixing parts 51 of the brackets 50A and 50B are placed in the grooves 87 of the frame 8 and screwed to the frame 8 to form a frame with handrails. Next, the frame 8 is placed along the visible surface of the frame 7 of the building skeleton 6 and screwed to the frame 7. At this time, the fixing parts 51 are fastened together to the frame 8 and the frame 7. Since the handrail mounting structure 10B is formed by installing the frame 8 and the handrail 11B in this way, in addition to the frame 7 (base) on which the frame 8 is installed, there is no need to go to the trouble of searching for a base on which the handrail 11B is installed, and there is no need to go to the trouble of newly forming a base on which the handrail 11B is installed.

[0020] [Variations] In the first embodiment, the projected surfaces of the base 20 and the fixing portions 31 of the brackets 30A and 30B are flush with the projected surfaces of the upper frame 81 and the lower frame 82 to form a projected surface 85 that is continuous in the Y-axis direction; however, this is not limited to the above, and for example, the projected surfaces of the base 20 and the fixing portions 31 may be positioned at a position that protrudes or is recessed in the X-axis direction relative to the projected surfaces of the upper frame 81 and the lower frame 82. In the second embodiment, the groove portion 87 is formed in the frame 8, but this is not limiting, and the groove portion 87 may be formed in the frame portion 7 of the building skeleton 6, or may be formed in both the frame portion 7 and the frame 8. In addition, the fixing portions 51 of the brackets 50A and 50B are attached to the frame 8, but may be attached to the frame portion 7. In the first and second embodiments, two brackets 30A, 30B (50A, 50B) are provided, but one or three or more brackets may be provided as long as the brackets are capable of supporting the grip body 40 (60). In the first and second embodiments, the handrails 11, 11B are installed on the door end side, but they may be installed on the door trailing edge side or in other locations. In the first and second embodiments, a sliding door 2 is installed at the entrance 1, but this is not limited to the above, and various sliding or swinging doors, doors, and other fittings that open and close the entrance 1 may be installed.

[0021] [Summary of the invention] The handrail mounting structure of the present invention is a handrail mounting structure for mounting a handrail to a building structure that defines an entrance / exit, characterized in that a frame is installed on the building structure, the frame is formed by dividing it in its longitudinal direction, and the handrail comprises a base that is attached to the building structure at the divided part, a bracket fixed to the base, and a grip body supported by the bracket. According to the handrail mounting structure of the present invention, the handrail base is attached to the building frame at the dividing portion, so the handrail can be installed at the installation location of the building frame where the frame is to be installed. In other words, the building frame already has a base such as a pillar at the location that defines the entrance, and the handrail can be installed by installing the frame on this base, which eliminates the need to search for a location to install the handrail in addition to the location where the frame is to be installed and the need to form a new base, improving the workability of installing the handrail. Furthermore, since the base of the handrail is positioned at the dividing portion, this base can be used to easily configure the appearance of part of the frame, improving the design. Furthermore, the handrail can be positioned close to the entrance, allowing people passing through the entrance to easily grasp the handrail. In addition, when the dividing section is formed by cutting out the frame, the vertical position and vertical length of the dividing section can be set appropriately, making it possible to install handrails of various shapes.

[0022] The handrail mounting structure of the present invention is a handrail mounting structure for mounting a handrail to a building structure that defines an entrance / exit, characterized in that a frame is installed on the building structure, the handrail comprises a bracket attached to the building structure or the frame and a grip body supported by the bracket, and the bracket is disposed between the building structure and the frame. According to the handrail mounting structure of the present invention, a bracket is placed between the building structure and the frame, so that the handrail can be installed by performing frame installation work on the base such as a pillar that is already present in the part of the building structure that defines the entrance / exit. This eliminates the need to find a location to install the handrail in addition to the installation location for the frame, and the need to form a new base, thereby improving the workability of installing the handrail. Furthermore, since the handrail does not have the aforementioned base, there is no need to divide the frame in its longitudinal direction to position this base, and the bracket is placed in the groove, resulting in an inconspicuous configuration, improving the design. Furthermore, the handrail can be positioned close to the entrance, allowing people passing through the entrance to easily grasp the handrail.

[0023] In the handrail mounting structure of the present invention, the bracket has a fixing portion fixed to the end of the base facing the frame, and an arm portion protruding from the fixing portion, and a covering edge portion covering the fixing portion is formed along the projection direction at the end of the base, and the fixing portion may be positioned between the building structure and the covering edge portion. According to this configuration, the fixing portion of the bracket can be hidden by the covering edge portion of the base, and even if there is the above-mentioned divided portion, it is possible to form the appearance of a continuous picture frame in the longitudinal direction.

[0024] In the handrail mounting structure of the present invention, the frame may be formed with a groove in which the bracket is disposed, and the bracket may be attached to the frame. This structure eliminates the need to form grooves in the building frame on-site to accommodate the brackets. Also, the frame with handrails can be constructed by attaching the brackets to the frame in advance, which reduces the effort required for installing the frame and handrails.
