[Industrial applications]

 The present invention relates to a handrail mounting structure used for stairs and balconies of houses.

[0002]

[Prior art]

 3 (a) and 3 (b) show a handrail mounting structure installed on a staircase of a house, a veranda, or the like. The handrail bracket 1 is provided with a projecting piece 6 projecting laterally at the upper end thereof, and the handrail 4 is provided with a recess 8 on the lower surface. Then, the handrail bracket 1 is arranged from below the handrail 4, the protruding piece 6 is fitted into the recess 8 provided in the lower surface of the handrail 4, and the screw 12 is screwed into the protruding piece 6 to support the handrail 4. It is fixed.

On the back surface of the handrail bracket 1, a plurality of connecting pieces 7 projecting in the lateral direction are provided in the vertical direction. Each horizontal lattice 5 is arranged on the back surface of each connecting piece 7, and the connecting piece 7 is provided. A screw 12 is screwed in from above and the horizontal lattice 5 is fixed by screwing. Further, when the handrail 4 and the horizontal lattice 5 cannot be formed by a single long material without a joint, a joint material 9 is provided at the end of the handrail 4 and the horizontal lattice 5, and the handrail 4 and the horizontal lattice 5 are provided. It is formed to have a required length by the main connection.

[0004]

[Problems to be solved by the device]

 However, if the handrail 4 and the horizontal lattice 5 are connected using the joint material 9 as described above, the strength of the handrail 4 and the horizontal lattice 5 may decrease, and as the handrail 4 is used, There was a possibility that the joint of the joint material 9 would open the joints at the joints and create a gap. Therefore, it is conceivable to increase the length of each of the handrail 4 and the horizontal lattice 5 so that the joint material 9 is not used or the number of the joint members 9 to be used is reduced. The handling of cargo during transportation and construction was inconvenient.

The present invention has been made in view of the above points, and it is possible to connect a handrail or a horizontal lattice to a handrail bracket without using a joint member, and to attach the handrail or the horizontal lattice to the handrail bracket. It is an object of the present invention to provide a handrail mounting structure in which strength is not reduced and joints are not opened.

[0006]

[Means for Solving the Problems]

 In the handrail mounting structure according to the present invention, a tubular handrail fitting 2 having openings on both sides is provided at an upper end of the handrail bracket 1, and a tubular horizontal lattice fitting 3 having openings on both sides is provided. A plurality of handrails 4 are provided vertically along the handrail bracket 1, and the ends of the handrail 4 are fitted into the openings on both sides of the handrail fitting member 2 and the handrails 4 are fixed to the handrail fitting member 2. Characterized in that the ends of the horizontal lattices 5 are fitted in the openings on both sides of the horizontal lattice fittings 3, and the respective horizontal lattices 5 are fixed to the horizontal lattice fittings 3. Is.

[0007]

[Action]

 The ends of the handrails 4 are fitted and fixed in the openings on both sides of the handrail fitting 1 of the handrail bracket 1 respectively, and are respectively inserted into the openings on both sides of the horizontal grid fitting 3 of the handrail bracket 1. Since the end portions of the horizontal grid 5 are fitted and fixed, the handrail 4 and the horizontal grid 5 can be directly attached to the handrail bracket 1 without using the joint material 9.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments. As shown in FIG. 2, the handrail bracket 1 is formed by providing a handrail fitting member 2 on the upper end portion of the column 1a and providing a plurality of horizontal lattice fitting members 3 on the back surface along the vertical direction. Yes, the lower end of the column 1a is fixed to the floor or the ground (not shown).

The handrail fitting 2 has a tubular shape with openings on both sides, and the inner peripheral cross-sectional shape is the same as the outer periphery of the handrail 4. A fixing piece 10 protruding in the lateral direction is provided at the lower edges of the openings on both sides of the opening, and a screw hole 11 for fixing the handrail 4 is provided at the substantially central portion by opening vertically. The horizontal lattice fitting member 3 has a tubular shape with openings on both sides and has the same cross-sectional shape as the horizontal lattice 5, and is provided so as to project laterally along the up-down direction of the back surface of the column 1a. Further, the horizontal lattice fitting member 3 is provided with screw holes 11 for fixing the horizontal lattice 5 so as to open in the front and rear.

The handrail 4 is provided with recesses 8 having substantially the same shape as the fixed piece 10 on the lower surfaces of both ends. Then, as shown in FIGS. 1 (a) and 1 (b), the ends of the handrail 4 are fitted into the openings on both sides of the handrail fitting material 2, and the fixing pieces 10 are fitted into the recesses 8, The screw 12 is screwed into the fixing piece 10 from the lower side of the screw hole 11 and the handrail 4 is fixed by screwing. Further, as shown in FIGS. 1A and 1B, the end portions of the horizontal lattice 5 are fitted into the openings on both sides of the horizontal lattice fitting member 3, respectively. Then, a screw 12 is screwed into the horizontal lattice fitting material 3 through a screw hole 11 provided therein, and the horizontal lattice 5 is fixed by screwing.

Further, since the handrail brackets 1 are installed at a plurality of locations, the length of each of the handrails 4 and the horizontal grids 5 mounted between the handrail brackets 1 can be shortened, and the handrails 4 and the horizontal grids can be reduced. The handling of the item 5 during transportation and construction becomes easy.

[Effect of device]

 As described above, according to the present invention, the tubular handrail fittings having openings on both sides are provided at the upper end of the handrail bracket, and the tubular horizontal lattice fittings having openings on both sides are provided along the handrail bracket. A plurality of vertical rails, and fit the ends of the handrail into the openings on both sides of the handrail fitting, and fix each handrail to the handrail fitting. Since the ends of the horizontal grids are fitted in the openings of the horizontal grids and the horizontal grids are fixed to the horizontal grid fitting material, the handrail and horizontal grids can be directly connected to the handrail brackets and attached to the rails. The horizontal lattice can be attached without using a joint material, and it is possible to prevent the strength of the handrail at the joint part from decreasing and the joint from opening.
