Description

  The present invention relates to a handrail with a chair that is installed at an entrance of a building such as a front door and assists an operation of putting on and taking off footwear when entering and leaving the building.

JP, 2004-16238, A Conventionally, in the entrance and exit of buildings, such as a front door, a level difference is often provided between dirt and an indoor floor. Normally, this step was set to be a relatively large step suitable for healthy people to sit down and put on and take off footwear such as shoes when going out or returning home. . Therefore, it was very difficult for the elderly and the disabled to climb up and down this level difference. Therefore, as countermeasures, it has been proposed to lower this step and to provide a handrail for supporting the body on the wall surface in the vicinity of the step in order to assist the ascending and descending. However, when the level difference is made small in this way, putting on and taking off shoes becomes a very difficult operation for the elderly and the disabled. Therefore, as another countermeasure, it has been proposed to lower the level difference and to provide a bench between the soils of the entrance instead.

  In JP 2004-16238, in a bench with a handrail provided in the vicinity of a raised ridge having a step at an indoor entrance, it is fixed to a seat surface member constituting a bench on which a user is seated and a wall surface in the vicinity of the raised ridge, A handrail member having a vertical direction portion arranged in a vertical direction to assist a user's movement and a horizontal portion arranged in a horizontal direction continuously to the vertical direction portion, and the seat member is There has been proposed a handrailed bench characterized in that it is connected to a handrail member at the horizontal portion.

  In the bench with a handrail proposed in Japanese Patent Application Laid-Open No. 2004-16238, since the handrail member is integrally connected to the seat member, if the standard mounting position is set, the connection between the two can be performed. Although it does not vary depending on the method, construction is simplified, workability and total design are improved, and the price can be reduced, but the handrail can be attached to the wall surface, so that the wall surface strength is weak. There was a problem that it was difficult to install. In addition, since the bench is fixed, there is a problem that it is easily disturbed when the bench is not used.

  Therefore, the present inventor provides a handrail with a chair that can be installed only on the floor surface and can store a seat surface when the chair portion is not used.

  The handrail with a chair according to claim 4 of the present invention is characterized in that the seat surface and the connecting rod are connected by a damper hinge and a hinge with a latch. The seating surface does not fall even if the hand is released when descending, and the stored state of the seating surface is easily maintained.

The present invention will be described below with reference to the drawings.
FIG. 1 is a front view showing an example of a storage state of a seat surface of a handrail with a chair according to the present invention.
In the figure, reference numeral 1 denotes a support, which is erected vertically from the floor surface. A handrail cap 2 is provided between the upper ends of the pair of support columns 1. A position from the center of the column 1 to the base is connected by a connecting rod 3, and a base end of a seating surface 4 is rotatably connected to the connecting rod 3 via a damper hinge 5 and a latched hinge 6. In FIG. 1, plate-like support legs 7 are provided on the back surface of the seat surface 4.

  FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1 and shows a state in which the seating surface 4 is horizontal by a two-dot chain line. The base end of the support leg 7 is rotatably connected to the back surface on the front end side of the seat surface 4. A link bar 8 is rotatably provided between the base of the support leg 7 and the connecting rod 3, and the center of rotation of the base end of the seat surface 4, the center of rotation of the lower end of the support leg 7, and the link bar 8. The distance between the pivot centers at both ends is equal to the distance between the opposite sides to form a Robert link, and when the seat surface 4 is pivoted up and down, the support leg 7 is parallel to the support column 1. It is designed to be vertical. In this example, the connecting rod 3 is formed of a plate-like body, but the present invention is not limited to this, and a mold such as a tube may be used as appropriate.

  FIG. 3 is an enlarged view of a front view showing a state in which the support leg 7 is seen through, and a portion indicated by a broken line is a portion hidden behind the support leg 7. The base ends of the connecting rod 3 and the seat surface 4 are rotatably connected by a damper hinge 5 and a hinge 6 with a latch. The support leg 7 is connected to the upper end of the seat surface 4 at the upper end in the figure so as to be rotatable by a pair of side hinges 9. The upper center of the support leg 7 is rotatably connected to the link bar 8, and the lower end of the link bar 8 is connected to the connecting rod 3.

  In this example, the handrail headboard 2 is provided with irregularities for engaging fingers on the lower surface, but an appropriate shape such as a circular cross section or an oval shape may be used. The handrail cap 2 may be made of a suitable material such as wood, synthetic resin, or metal tube, but a metal mold such as a metal tube covered with a soft synthetic resin is preferably used.

  The damper hinge 5 according to the present invention only needs to use an oil damper or an air damper combined with the hinge as appropriate. When the seat surface 4 is lowered, the speed when the seat surface 4 is lowered is released and the hand is released halfway. However, the seat surface 4 descends safely.

  4 is a front view of the latched hinge 6, FIG. 5 is a sectional view taken along the line BB in FIG. 4, and FIG. 6 is a sectional view taken along the line BB in FIG. The figure is shown. A latch 62 provided in the housing 61 is pressed from behind by a pressing spring 63 and is in contact with a cam 64. The cam 64 has a flat upper surface and a left side surface, and the latch 62 is held at the position of the upper surface and the left side surface. The action of the hinge 6 with the latch prevents the seat surface 4 from falling even when the seat surface 4 is stored in a vertical state.

It is a front view which shows an example of the accommodation state of the seat surface of the handrail with a chair of this invention. It is AA sectional drawing of FIG. It is an enlarged view of the front view which shows the state which saw through the support leg. It is a front view of a hinge with a latch. It is BB sectional drawing of FIG. It is sectional drawing in the BB position of FIG. 4 when a seat surface is made into a horizontal state.
