Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a decorative cover device for a fixed pipe.
[0002]
[Prior art]
When fixing a handrail device or the like to the installation base 1 such as a wall surface, it is necessary to fix the handrail rod itself or a bracket or the like to the installation base, and after fixing, the fixing part to the installation base may be covered with a decorative cover. Is called.
[0003]
For example, as an application to a handrail device, one described in Japanese Patent Application Laid-Open No. 2000-45478 is known. In this conventional example, the decorative cover is constituted by a pair of cover bodies that externally fit the end portions of the handrail pipe in a connected state, and the attachment to the handrail pipe is performed by connecting the cover bodies and then providing the protrusions provided on each cover body. This is done by engaging and fixing the one part to the mounting base fixed to the wall surface side.
[0004]
[Problems to be solved by the invention]
However, the conventional example described above has the following drawbacks. First, in order for the decorative cover to have a structure in which the convex piece is locked to a mounting base fixed in advance on a wall surface or the like and held in a predetermined position, it is necessary to provide locking means on both the mounting base and the cover body. In addition, the structure is complicated, and a locking operation to the mounting base is required, so that the mounting workability is also lowered. Further, since the cover body is elastically engaged with the mounting base in the mounted state, it is difficult to remove and the maintainability is poor.
[0005]
Furthermore, the cover body is different only in the connecting portion, and it is necessary to use two types of covers having substantially the same overall shape, so that the types of parts increase.
[0006]
The present invention has been made to solve the above-described drawbacks, and has an object to provide a decorative cover device for a fixed pipe that has a simple structure and good mounting workability. Another object of the present invention is to provide a decorative cover device for a fixed pipe that can reduce the types of components by sharing the components.
[0007]
[Means for Solving the Problems]
According to the present invention, the object is
It consists of a pair of split covers 3 that externally fit the outer periphery of the fixed pipe 2 fixed to the installation base 1 in a connected state,
Each divided cover 3 is provided with elastic legs 4 that extend in the longitudinal direction of the fixed pipe 2 at the corresponding edges of the fixed pipe 2 and are separated into a plurality of pieces by the slits 4a and can be elastically deformed independently .
At the free end of the elastic leg 4 separated into a plurality, a pressing protrusion 5 that presses against the outer peripheral wall surface of the fixed pipe 2 is provided ,
In addition, the elastic leg 4 is a decorative cover device for a fixed pipe having elasticity that presses the pressing protrusion 5 against the fixed pipe 2 with a pressure by which the pair of connected divided covers 3 are held at appropriate positions on the fixed pipe 2. Achieved by providing.
[0008]
In the present invention, the fixed pipe 2 is a generic term for a connecting member for connecting a predetermined device and an installation base 1 such as a wall surface. In the handrail device, a bracket for supporting a handrail rod, Alternatively, it may be a housing such as a support pipe, or a handrail rod itself.
[0009]
The divided cover 3 constituting the decorative cover device can be connected in a shape that fits the outer periphery of the fixed pipe 2, and the pressing protrusion 5 of each divided cover 3 is in pressure contact with the outer peripheral wall surface of the fixed pipe 2 in the connected state. An appropriate sliding resistance is generated between the decorative cover and the fixed pipe 2 due to the pressure contact of the pressing protrusion 5, and therefore, it can be held at an appropriate position on the fixed pipe 2.
[0010]
Therefore, in the present invention, the decorative cover device is attached by simply connecting the two divided covers 3 at appropriate positions on the fixed pipe 2 and then shifting them until they come into contact with the installation base 1 such as the wall surface along the fixed pipe 2. As a result, workability is improved. Further, since no connecting means is required on the installation base 1 side, the structure is simplified. Furthermore, since the decorative cover is once moved to an appropriate position on the fixed pipe 2 and can be removed simply by releasing the connection between the divided covers 3, the maintainability is improved.
[0011]
In the connected state, a force in the separation direction is applied to the connecting edge 6 between the divided covers 3, but the divided covers 3 are engaged with each other in the direction orthogonal to the connecting edge at the outer front end portion of the connecting edge 6. If comprised in this way, the clearance gap generation | occurrence | production in the connection edge 6 can be prevented completely.
[0012]
In addition, the decorative cover device
It consists of a pair of split covers 3 formed in the same shape that fits the outer periphery of the fixed pipe 2 fixed to the installation base 1 in a connected state,
Each split cover 3 has a locking piece 7 projecting in the shape of a tongue piece toward one of the pair of connecting edges 6 in contact with the other split cover 3 toward the back side, with piece 7 Rutotomoni provided with engagement holes 8 engageable, the elastic leg 4 extending in the longitudinal direction of the fixed pipe 2 to the fixed pipe 2 corresponding edge,
The elastic leg 4 is provided with a pressing protrusion 5 that presses against the outer peripheral wall surface of the fixed pipe 2.
The elastic legs 4 are provided with elasticity that presses the pressing protrusions 5 against the fixed pipe 2 with a pressure at which the pair of connected divided covers 3 are held at appropriate positions on the fixed pipe 2.
A pair of split covers 3 are brought into contact with each other so that the engagement holes 8 are positioned at the lower ends of the locking pieces 7 , and then twisted in the engagement direction to be engaged and connectable, and fixed in the connected state. It can be configured to be held at an appropriate position on the pipe 2 .
[0013]
In this case, since only one type of divided cover 3 is required, the number of component types is reduced, and the manufacturing efficiency is improved.
[0014]
