Abstract

[Problem] To improve safety by preventing floor-mounted handrail joints from slipping off the support posts of floor-mounted handrails. [Solution] In the present invention, in a floor-standing handrail joint (1) for connecting a support column (4) and a connecting bar (3) of a floor-standing handrail (2), a movable pressing body (19) that presses against the support column (4) is provided on the joint (7, 8) for attachment to the support column (4) via an elastic buffer (20). Furthermore, a pair of pressing bodies (19) and buffers (20) are arranged opposite each other on a pair of joints (7, 8) that clamp the support column (4). Furthermore, the pressing bodies (19) and buffers (20) are provided on the joints (7, 8) so as to be detachable. Furthermore, recesses (17, 32) are formed in the joints (7, 8) to accommodate the pressing bodies (19) and buffers (20) when the joints (7, 8) are attached to the support column (4).

Description

This invention relates to a joint for floor-mounted handrails, for connecting the support posts and connecting bars of a floor-mounted handrail. Floor-standing handrails, which can be placed on the floor and moved, are used to assist elderly people and those requiring care when standing up and sitting down indoors. This floor-standing handrail can be used as an assistive device for elderly people and those requiring care when walking indoors. Multiple handrails can be connected using connecting bars and installed in rooms, corridors, and stairwells. In this process, the support posts and connecting bars of the floor-mounted handrail are connected using a floor-mounted handrail joint. This floor-mounted handrail joint secures the support posts of the floor-mounted handrail by clamping them with a pair of couplings (see, for example, Patent Document 1). Japanese Patent Publication No. 2021-116535 A front view illustrating the usage state of the floor-mounted handrail joint according to the present invention.Plan view (a), front view (b), bottom view (c), and rear view (d) showing the first joint.Plan view (a), front view (b), bottom view (c), and rear view (d) showing the second joint.Enlarged cross-sectional view (a) showing the second joint, and enlarged cross-sectional view (b) showing the first joint.An enlarged cross-sectional diagram illustrating the installation method for floor-mounted handrail joints.An enlarged cross-sectional diagram showing the floor-mounted handrail joint installed.Rear perspective view (a) and front perspective view (b) showing the pressing element, rear perspective view (c) and front perspective view (d) showing the buffer element.Plan view (a) and front view (b) showing a hinged joint for a floor-mounted handrail. The specific configuration of the floor-mounted handrail joint according to the present invention will be described below with reference to the drawings. As shown in Figure 1, the floor-mounted handrail joint 1 is used to connect floor-mounted handrails 2, which are placed on the floor of an indoor building, using an extendable connecting bar 3. One side is connected to the support column 4 of the floor-mounted handrail 2, and the other side is connected to the connecting portion 5 at the end of the connecting bar 3. A weight 6 is detachably attached to the support column 4 of the floor-mounted handrail 2 to prevent tipping. As shown in Figures 2 to 7, this floor-mounted handrail joint 1 is detachably attached to the support post 4 of the floor-mounted handrail 2 by fastening a pair of joints (first joint 7 and second joint 8) for clamping the support post 4 of the floor-mounted handrail 2 with fasteners 9 such as bolts. The first joint 7 has a connecting portion 10 for detachably connecting the connecting portion 5 at the end of the connecting bar 3, a fastening portion 11 for fastening with the second joint 8, and a mounting portion 12 for attaching to the support column 4 of the floor-standing handrail 2. The connecting portion 10 has an internal female thread 13, allowing the connecting portion 5 of the connecting bar 3 to be connected freely, both vertically and detachably. The fastening portion 11 has internal female threads 14, 14 formed at vertical intervals, allowing the second joint 8 to be detachably fastened with fasteners 9, 9. The mounting portion 12 has an arc-shaped inner circumferential surface 15 that follows the shape of the outer circumferential surface of the support column 4 of the floor-mounted handrail 2. A fastening portion 11 is formed on one side of this inner circumferential surface 15, and a convex claw-shaped piece 16 that extends vertically and protrudes outward is formed on the other side of the inner circumferential surface 15 (opposite the fastening portion 11, with the inner circumferential surface 15 in between). The inner circumferential surface 15 may have the same radius of curvature as the outer circumferential surface of the support column 4, or it may have a slightly larger radius of curvature than the outer circumferential surface of the support column 4. Furthermore, the mounting portion 12 has a recessed area 17 formed on the inner side of the inner circumferential surface 15, and through holes 18, 18 are formed in the recessed area 17, spaced apart vertically, penetrating both the front and back (inside and outside). A pressing body 19 for pressing against the support column 4 of the floor-mounted handrail 2 is attached to the recess 17 of this mounting portion 12 via an elastic buffer 20, allowing it to move back and forth and be attached and detached. The pressing body 19 has a thin plate with an arc-shaped cross-section that extends vertically, and has an arc-shaped front surface 21 that follows the outer circumferential surface of the support column 4 of the floor-mounted handrail 2, and an arc-shaped rear surface 22 that follows the inner circumferential surface of the recess 17. At the rear of this plate, cylindrica
