Description

  The present invention relates to a handrail device provided at an opening of a wall.

As a conventional handrail device, a grip part is provided partially or over the entire length of at least one vertical frame of a frame body to which a door is freely opened and closed (Patent Document 1), or for making up an opening surface. It is a decorative frame and includes an extended portion extending toward at least one indoor side so that the extended portion can be grasped by a hand to maintain a posture when entering and exiting the opening. The thing (patent document 2) provided with the formed handrail part is known.
Japanese Utility Model Publication No. 7-10362 JP-A-9-125825

  However, in these handrail devices, a handrail portion is provided in a vertical frame to which a door is attached, in which a grip portion is provided partially or over the entire length, or an extended portion that extends toward the indoor side of the decorative frame. Therefore, each time the size or location of the frame of the opening or the decorative frame changes, the position of the grip or handrail must be changed, so the degree of freedom for providing the grip or handrail is small.

  The problem to be solved by the present invention is that the degree of freedom of attaching the handrail in the opening is large.

In order to solve the above-described problems, the present invention provides an opening in which a casing is provided by fitting a fixing end of a casing into a groove formed by extending in a length direction on an opening surface side of an opening frame of a wall . A protrusion that fits into the groove; a base end portion that extends from the front end of the protrusion toward the outside of the opening and has the same cross-sectional shape as the casing together with the protrusion; and the base end A handrail device having a grip portion that protrudes forward from the portion is provided to replace a part of the casing by fitting the protrusion into the groove .

  By doing so, the protrusion formed on the base end portion of the handrail fits into the groove of the opening frame to which the casing is fixed, so that the handrail can be provided at any place where the groove is present. it can. Moreover, even if it is the opening part to which the casing is already attached, since a part or all of the casing can be removed and a handrail can be provided instead, it is possible to cope with renovation. Further, by providing a handrail in the groove of the opening frame, the handrail supports the pedestrian so that it can safely walk when passing through the opening.

  Furthermore, the handrail is preferably provided over substantially the entire vertical length of the opening frame. The handrail is provided over substantially the entire vertical length of the opening frame, so that it is safely supported when a person stands or passes through the opening of a child. In particular, it is safely supported when an elderly person passes through an opening with a wheelchair or the like, moves inside the room, or sits down.

  Next, each requirement constituting the present invention will be described in more detail. This handrail device can be applied to a case where an opening is provided on a wall of a building such as a house or a store, and a casing is provided along the opening frame. In this case, the opening part provided in the wall between rooms, the opening part provided with a door, a sliding door, etc., or the opening part of a window are included.

  The handrail device is used by all pedestrians that pass through or move close to the opening, and can be optimally used particularly when elderly people move indoors or sit down.

  The handrail is not particularly limited as long as it has a substantially rod-shaped grip part that can be gripped by a person and a base end part extending to the grip part, and a protrusion is formed on the base end part. As the cross-sectional shape of the grip portion, a circle, an ellipse, a rectangle, a polygon, or the like can be used. The cross-sectional size of the grip portion is preferably about 25 to 45 mm in a circular shape although it depends on the material, and about 32 to 35 mm in the case of wood. The length of the grip portion of the handrail is not particularly limited, but may be selected as appropriate within a range of, for example, 600 mm to the entire vertical length of the opening frame. In the case where the handrail is provided only in a part of the groove of the opening frame for the casing, the casing is provided in a portion other than the handrail and connected to the handrail.

  The shape of the protrusion formed on the base end portion is not particularly limited, but may be a rectangle, a deformed rectangle, a hook shape, or the like, and may be a shape that is engaged with the groove of the opening frame into which the protrusion is fitted. The groove of the opening frame into which the protrusion is fitted is the same as the groove of the opening frame into which the fixing end of the casing is fitted. For example, the front or back surface (surface facing the chamber side) of the vertical frame or upper frame forming the opening ).

  According to the present invention, since the handrail can be provided in place of the casing in the opening where the casing is provided, the degree of freedom of attaching the handrail in the opening is great.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a handrail device according to the present invention will be described in detail with reference to the drawings. 1 to 8, the same or equivalent parts are denoted by the same reference numerals.

  FIG. 1 is a front view showing an embodiment of a handrail device according to the present invention. The handrail device of the first embodiment is provided in the opening 12 of the wall between the rooms of a building such as a house.

A door 30 is provided in the opening 12 and is supported by the right vertical frame 14 in the figure via two upper and lower hinges 32. A handle 34 is provided at an intermediate height position on the left side in the left-right direction of the door 30.

  Further, a handrail 1 is provided at an intermediate position in the vertical direction of the left and right vertical frames 14. The upper end and the lower end of the handrail 1 are continuous with the casing 20. The length of the handrail 1 is, for example, 600 mm, but is not limited to this length.

  FIG. 2 is a side view of the main part as viewed from the direction of arrow A with the door 30 in FIG. 1 opened. 3 is a cross-sectional view taken along the line BB in FIG. As shown in FIG. 2, the handrail 1 is provided at a part of the length of the vertical frame, and includes a grip portion 4 extending in a direction along the vertical frame 14 and a base end portion 6 extending to the grip portion 4. And have. The grip portion 4 and the base end portion 6 are integrally formed at the upper and lower portions of the handrail 1, and reinforcing ribs 8 are appropriately provided in the middle to reinforce the strength of the grip portion 4.

  As shown in FIG. 3, the opening 12 is formed by, for example, assembling a vertical frame 14 and an upper frame (reference numeral 16 in FIG. 1) in a gate shape on a pillar 38, which is a cadaver, with a tree 22. On the outside of the pillar 38, for example, a gypsum board 36 is provided. Further, a protrusion 7 is formed on the base end portion 6. The front end side of the protrusion 7 is fitted into a groove 18 of a vertical frame to which the casing 20 is fixed. The grip portion 4 is made of wood and has a substantially rectangular cross section. The grip portion 4 has a cross-sectional size of 35 mm in width and 25 mm in thickness.

  The shape of the base end portion 6 including the protrusion 7 is substantially L-shaped. The shape and size of the vertical frame groove 18 into which the protrusion 7 is fitted are the same as the groove into which the fixing end of the casing 20 is fitted, and the front or back surface of the vertical frame 14 forming the opening (on the chamber side). (Facing surface).
