Description

  The present invention relates to a handrail structure capable of switching a plate-shaped handrail body between a vertical handrail mode and a horizontal arm support mode.

  In the handrail structure according to the present invention, a handrail body formed in a plate shape can be mounted in, for example, a vertical posture (a posture in which the plate surface faces sideways) and a horizontal posture (a posture in which the plate surface faces upward) with respect to adjacent columns. However, this type of handrail structure is disclosed in Patent Document 1, for example. The handrail of Patent Document 1 includes a handrail member having a P-shaped cross section and a pair of bracket members that support the handrail member. The handrail member integrally includes a handrail surface having a semicircular cross section and a flat elbow rest surface that supports the user's elbow. The bracket member includes a fixed portion fixed to the wall surface and a rotating portion fixed to the hand rail member, and the entire hand rail member is supported by rotatably supporting the rotating portion by the fixed portion. Can be switched between a state in which the handrail surface is directed upward and a state in which the entire handrail member is in a horizontal posture and the elbow rest surface is directed upward. Position adjusting means for holding the handrail member in a vertical posture and a horizontal posture is provided between the fixed portion and the rotating portion. The position adjusting means includes an urging member composed of a spring and a pin, two movable stoppers, and two through holes provided in the fixed portion, and one of the movable stoppers engages with the through hole.

  According to the handrail structure of Patent Document 1, by changing the attitude of the handrail member by 90 degrees, it is possible to switch between a state in which the handrail surface is upward and a state in which the elbow rest surface is upward. However, the rotating portion is rotatably supported by the fixed portion, and each posture is held in position by engaging one movable stopper with the through hole. Therefore, when the movable stopper is pushed against the urging force of the spring due to mischief or the like, the posture of the handrail member may change suddenly, which causes a problem in safety. Further, since the position adjusting means holds the posture of the handrail member by engaging one movable stopper with the through hole, a large tilting moment is applied to the movable stopper when the user leans against the handrail member. Acts in a concentrated manner. Therefore, the handrail member is easy to rattle, and it is difficult to support the user in a stable state, particularly in a state where the elbow rest surface faces upward. Furthermore, since the fixing portion needs to be fixed to the surrounding wall of the room, it cannot cope with a case where a handrail is to be provided beside the bed facing the center of the room, for example.

  The object of the present invention is to improve the safety during use by firmly fixing and supporting the handrail body in the handrail mode or the arm support mode without rattling, and further installing the handrail body at an arbitrary installation location.

Further, the second connecting body 42 of the rear stay 24 is connected and fixed. The front handrail body 2 is fixed to a pair of left and right stays 24 on the front side of the support column 1A, and the rear handrail body 2 is fixed to a pair of left and right stays 24 on the rear side of the support column 1A.

  In the handrail structure of the present invention, a handrail bracket 22 is constituted by a stay 24 fixed to a plate-shaped handrail main body 2 and a bracket base 23 fixed to a column 1A, for example, and a second connecting body 42 provided on the stay 24 is provided. The handrail main body 2 is supported by the bracket base 23 by engaging with the first connecting body 41 provided on the bracket base 23. Further, the connecting posture of the second connecting body 42 with respect to the first connecting body 41 can be switched between the handrail mode and the arm supporting mode, and the stay 24 in each mode can be fixed to the bracket base 23 by the stay fastening body 43.

  According to such a handrail structure, the user's convenience can be improved by switching the use mode of the handrail body 2 between the handrail mode and the arm support mode according to the user's physical condition and preference. Further, in each usage mode, the first connecting body 41 and the second connecting body 42 are engaged with each other, and the stay 24 is firmly fastened and fixed to the bracket base 23 by the stay fastening body 43. There is no room for the main body 2 to wobble, and it is possible to assist the user's walking, standing up motion or sitting motion in a stable state. Therefore, according to the handrail structure of the present invention, the handrail main body 2 in the handrail mode or the arm support mode can be firmly fixed and supported without rattling, thereby improving the safety during use. In addition, when the handrail body 2 is supported by the adjacent column 1A, the handrail body 2 can be installed at an arbitrary position such as the bedside in the center of the room or between the bed and the entrance of the room. Can improve convenience.

  The bracket base 23 includes a joining ring 26, a connecting ring 27, and a ring fastening body 28. According to such a handrail structure, the joining ring 26 and the connecting ring 27 are joined to the peripheral surface of the support 1A, and the bracket base can be obtained simply by fastening both the rings 26 and 27 with the ring fastening body 28 with the height adjusted. 23 can be easily fixed to the column 1A. The first connecting body 41 includes an isosceles right triangle socket portion 44, a fixed joint seat 45 inclined at 45 degrees, a pair of fixed engagement bodies 46 formed on the inner surface of the socket portion 44, and the like.

The switching engagement body 51 is used. According to such a handrail structure, the stay 24 is connected to the connecting ring 27 and the stay fastening body 43 is screwed in a state in which the plug portion 49 and the socket portion 44, and the switching engagement body 51 and the fixed engagement body 46 are engaged. As a result, the fixed joint seat 45 and the switching joint seat 48 are brought into close contact with each other, and the stay 24 can be firmly fastened and fixed to the connecting ring 27. Therefore, even when the user leans against the handrail main body 2 and a large tilting moment acts on the connecting portion of the stay 24 and the connecting ring 27, the handrail main body 2 can be reliably prevented from wobbling. Compared to the structure, it is possible to assist the user in walking, standing up, or sitting down in a more stable state. Further, since the handrail body 2 can be switched between the handrail mode and the arm support mode simply by changing the assembly posture of the stay 24 with respect to the connecting ring 27, the labor required for the mode change can be saved.

  The female screw body 50 is embedded and fixed in each of the equal side portions of the plug portion 49, the stay fastening body 43 is screwed into the female screw body 50 from the bottom wall of the socket portion 44, and the plug portion 49 is fastened and fixed to the socket portion 44 inseparably. I did it. According to such a handrail structure, the stay fastening body 43 can be used in common in both cases where the handrail body 2 is supported in the handrail mode and in the arm support mode. The fastening structure of the socket part 44 can be simplified, and the manufacturing cost of the handrail structure can be reduced. Incidentally, when the female screw body 50 is provided at a portion that is not an equal side portion of the plug portion 49, for example, it is necessary to avoid the formation portion of the switching engagement body 51. Inevitable.

  In a state where the plug portion 49 is fastened and fixed to the socket portion 44 by the stay fastening body 43, one restriction claw 52 provided on the switching joint seat 48 is engaged with the restriction groove 53 at the upper end of the fixed joint seat 45. According to such a handrail structure, one of the restricting claws 52 engages with the restricting groove 53, and the tilting moment acting on the stay 24 is received in cooperation with the stay fastening body 43. Therefore, the connection between the stay 24 and the connecting ring 27 is achieved. Strength can be further strengthened.

  The stay 24 is formed in a hollow frame shape having an opening surface 37 with the fastening seat 35 and the peripheral frame portion 36, and the opening surface 37 is closed with a removable cover 39. According to such a handrail structure, by removing the cover 39, the fastening seat 35 can be easily fastened and fixed to the handrail body 2 by the adjustment screw body 58 that is screwed in from the opening surface 37 side. Assembling work can be performed quickly and easily. Further, when the handrail body 2 is used, the cover 39 is attached to the stay 24 and the opening surface 37 of the stay 24 is closed with the cover 39, so that the operating head of the adjustment bolt 58 is not visually recognized. Therefore, the appearance of the stay 25 when the handrail body 2 is supported in a handrail mode can be made clear. Even if the user's hand or arm may accidentally come into contact with the stay 25, the opening surface 37 is blocked by the cover 39, so that the hand or finger is caught on the opening edge of the peripheral frame portion 36. Can be prevented to improve safety during use.

  When the screw insertion groove 56 that is movable relative to the adjustment screw body 58 is formed in the left and right horizontally in the fastening seat 35, the interval between the column center axes of the adjacent columns 1A and 1A varies with respect to the target dimension. Even in this case, the handrail main body 2 and the adjusting bolt 58 can be moved along the screw insertion groove 56 to absorb the previous variation. Therefore, the assembly work of the handrail main body 2 with respect to the support | pillar 1A can be performed simply.

  Adjacent ends of the adjacent handrail main bodies 2 are connected to each other by a connection cap 61 and a bridge body 62. The connecting cap 61 and the bridging body 62 are engaged and connected by the concave and convex engaging bodies 67 and 68 that prevent relative movement from each other, and the bridging body 62 straddling the outer surface of the connecting cap 61 on the left and right is handrailed by the connecting bolt 69. It was made to fasten and fix to the mounting surface 13 of the main body 2. According to such a handrail structure, compared to the case where each handrail body 2 is independently supported by a plurality of pillars 1A, adjacent handrail bodies 2 can be integrated to increase the structural strength of the handrail structure as a whole. Safety can be improved as much as the structural strength of the structure is increased. Moreover, since the adjacent end of the adjacent handrail main body 2 is supported by the two struts 1A · 1 having a small adjacent distance, the connection strength of the connecting portion can be improved and each handrail main body 2 · 2 can be securely supported. .

  The adjacent ends of the adjacent handrail main bodies 2 are connected by the connecting cap 61 and the stay 24. Specifically, the connection bolt 69 inserted into the left and right horizontally long screw insertion grooves 56 formed in the fastening seat 35 of the stay 24 is screwed into the mounting surface 13 so that the adjacent handrail body 2 is connected by the stay 24. According to such a handrail structure, for example, two adjacent handrail main bodies 2 can be supported by the three support pillars 1A, so that the overall cost of the handrail structure can be reduced by the amount of use of the support pillars 1A being small. In particular, when a large number of handrail main bodies 2 are arranged along the wall surface of a long corridor, a group of handrail main bodies 2 are supported by a minimum number of pillars 1A to reduce the overall cost required for constructing the handrail structure. it can.

  A pair of connecting rings 27 and 27 are joined to the front and rear of the peripheral surface of the support 1A, both the rings 27 and 27 are fastened and fixed by a ring fastening body 28, and the stay 24 and the handrail body 2 are supported by the rings 27 and 27. I tried to do it. According to such a handrail structure, the handrail main body 2 can be arranged before and after the support column 1A, and the handrail main body 2 can be used properly according to the user's physical condition, physical condition, etc., so that the usability of the handrail structure can be improved. Further, the support mode of the front handrail body 2 and the rear handrail body 2 is made different between the handrail mode and the arm support mode, or the support height of the handrail main body 2 is made different even in the same support mode. A variety of rehabilitation using handrails that matches physical therapy.
