Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wooden handrail using wooden headboards.
[0002]
[Prior art]
As a handrail device configured to install a wooden headboard on a wall surface or the like via a bracket, for example, a device described in Japanese Utility Model Publication No. 7-29176 is known. In this conventional example, the bracket includes a cylindrical handrail receiving portion and is fixed to both ends of the headboard.
[0003]
However, this conventional example has a disadvantage that the design advantage of using the wooden headboard 2 cannot be utilized because both ends of the headboard are covered with brackets and the mouth is hidden. Further, as in the handrail described in Utility Model Registration No. 3000768, the one that supports the lower surface of the wooden headboard with the bracket is that the cuffs at both ends of the headboard project from the bracket. The problem that is caught. Therefore, the troublesome process of making both ends of the headboard into a curved shape close to the wall surface is necessary.
[0004]
[Problems to be solved by the invention]
The present invention has been made to eliminate the above drawbacks, and can be fixed to a wall or the like by exposing the head of the cap, and the sleeve of the user's clothes is not caught on the mouth. The purpose is to provide wooden handrails.
[0005]
[Means for Solving the Problems]
According to the present invention, the object is
A wooden headboard 2 having a flat seating surface 1 formed on the backs of both ends;
A bracket 4 having a fixing piece 3 to the seating surface 1;
The fixing piece 3 is fitted to a pin insertion hole 6 in which a rotation-preventing pin 5 is drilled in the vicinity of the mouth of the seat surface 1, and from the pin insertion hole 6 fitting position (see FIG. 2 (b)). And a wooden handrail having a cross-sectional shape that is fixed to the headboard 2 by being screwed at another place near the center line and that complements the notch for forming the seating surface of the headboard 2. Is achieved.
[0006]
The bracket 4 is screwed in a state in which the fixed piece 3 is in contact with the seat surfaces 1 formed on the back surfaces of both ends of the wooden headboard 2. In the present invention in which the bracket 4 is fixed to both ends of the headboard 2, for example, as shown in FIG. 3, the end of the headboard 2 does not protrude from the bracket 4, so that the free end of the headboard 2 (indicated by a broken line in FIG. 3). The clothes are prevented from being caught.
[0007]
Further, the bracket 4 and the headboard 2 are fixed by screwing at one place, and further, the bracket 4 and the headboard 2 are prevented from rotating at a position closer to the free end side than the screwing place. Although it is effective to make the bracket 4 as close as possible to the end (end portion) of the headboard 2 in order to prevent clothes from being caught at the end portion of the headboard 2, wood generally used as the headboard 2 Is hard and prone to cracking, and screwing in the vicinity of the end (end) of the material further increases the risk.
[0008]
A book in which the pin insertion hole 6 of the non-rotating pin 5 that does not generate a crack because it is formed by machining in advance is arranged on the free end side, and the screwing point where the crack is likely to occur is arranged near the center of the headboard 2 In the present invention, the bracket 4 can be fixed as close as possible to the end portion of the headboard 2, and the manufacturing yield can be improved by preventing the headboard 2 from cracking.
[0009]
If the cross-sectional shape of the fixed piece 3 is complemented with the notch portion for forming the seating surface 1 of the headboard 2 and is formed so as to match the general cross-sectional shape of the headboard 2 as a whole, There is no pain.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show an embodiment of the present invention. In this embodiment, the wooden handrail includes a wooden headboard 2 formed of a white ash material or the like, and a bracket 4 formed of a metal material such as a stainless material.
[0011]
The headboard 2 is a straight member having a circular cross section, and both ends (the end 2a) thereof are curved surfaces, and the seating surface 1 is formed on the rear surfaces of both ends by cutting the headboard into a flat shape. In order to leave the shape of the mouth end 2a as completely as possible, the depth d of the notch for forming the seating surface 1 is set as small as possible in consideration of the strength of the fixing piece 3 of the bracket 4 to be described later. Is done. Further, the length L of the seat surface 1 is also shortened as much as possible within a range in which an interval capable of preventing the rotation can be set between the anti-rotation pin 5 and the screw 7 which will be described later, and the pin insertion hole 6 is formed in the seat surface 1. And screw holes are drilled.
[0012]
On the other hand, the bracket 4 is formed by connecting the base fixing piece 8 and the fixing piece 3 with a connecting piece 9. The fixed piece 3 includes a support surface 3a corresponding to the seat surface 1 of the headboard 2, and the support surface 3a corresponds to a detent pin 5 to be inserted into the pin insertion hole 6 on the seat surface 1 side, and a screw hole. A screw insertion hole is provided.
[0013]
As shown in FIG. 2, the fixing piece 3 has a half-moon-like cross-sectional shape. When the fixing piece 3 is fixed to the headboard 2, the fixing piece 3 cooperates with the headboard 2 to form a general part (the seat surface 1 is formed). A cross-sectional shape (circular shape) in a portion not formed) is formed.
[0014]
On the other hand, as shown in FIG. 1, the base fixing piece 8 of the bracket 4 is further outward from the mouth 2a of the headboard 2 so that the mounting hole 8a formed in the center portion is not hidden behind the headboard 2 (headwood 2 The connecting piece 9 that connects the base fixing piece 8 and the fixing piece 3 is arranged in an obliquely inclined state.
[0015]
The bracket 4 is fixed to the headboard 2 after the detent pin 5 on the bracket 4 side is press-fitted into the pin insertion hole 6 of the headboard 2 and then a screw 7 such as a tapping screw is screwed into the lower screw hole. In the state where the bracket 4 is fixed, the terminal end 3b of the fixing piece 3 is coincident with the tree mouth 2a of the headboard 2 and the connecting piece 9 is continuously extended from the terminal end 3b. There is no possibility of catching clothes or the like without protruding only the end 2a. Moreover, when fixing to the wall surface 10 grade | etc., Since the attachment hole 8a of the bracket 4 is not hidden behind the headboard 2, attachment workability | operativity is also good.
[0016]
【The invention's effect】
As is apparent from the above description, according to the present invention, the head of the headboard can be exposed and fixed to a wall surface or the like, so that the design effect using wood for the headboard can be sufficiently exhibited. In addition, the end of the headboard does not protrude from the bracket, and the end of the fixed piece coincides with the head of the headboard and the connecting piece is continuously extended from the end, so that it is prevented from catching clothes.
