Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a handrail assembly device that allows easy assembly of a handrail having a front frame and a rear frame.

[Background technology]

Integrated handrails are used in factories, construction sites, etc., in which the front frame and the side frame are assembled together and then installed; After assembly, production was carried out by connecting them at a separate assembly location, resulting in poor work efficiency as the front frame and sleeve frame had to be moved frequently.

[Purpose of invention]

The object of the present invention is to provide a handrail assembly device that can improve the production efficiency of handrails by assembling and joining the front frame and the armrest frame at the same time.

[Disclosure of invention]

An embodiment of the present invention will be described below based on the drawings.

In the figure, the handrail assembly device 1 is the armrest frame assembly table 2.
In addition, in this embodiment, in order to assemble the sleeve frames B and B on both sides of the front frame A to form a handrail in the shape of a flat surface, there are provided a front frame assembly table 3 on both sides of the front frame assembly table 3, respectively. Sleeve frame assembly stands 2, 2 are arranged.

The front frame A is made of Kasagi a, as illustrated in FIG.
It can be formed by spanning a plurality of balusters c between the balusters and the balusters b, and in this embodiment, the balusters a and b are made of square metal tubes. Also, on both ends there are joints cut off at 45 degree angles.
Ca, Ca are provided, and Kasagi a and Shimogi b are
A through hole d into which the handrail c... is inserted on the facing surface.
is installed. The baluster c is also made of a metallic material, and can be press-fitted into the through hole d to form the integral front frame A. In addition, the sleeve frame B is provided with a joint Cb formed by a 45-degree notch only at one end, and is connected to a similar cap e, a lower girder f, and a baluster g that spans between them.
By having and integrally connecting the sleeve frame B
is formed.

The sleeve frame assembly table 2 has a contact piece 6 that comes into contact with the top surface of the cap e on one end edge of the base plate 5 whose top surface is flat, and a pressing piece 6 directed toward the contact piece 6 on the other end. 10 is provided with a pressing tool 11 that can advance and retreat,
Also, on one side edge facing the front frame assembly table 3, there is a side contact surface 13 formed from the side surface of the base plate 7 of the front frame assembly table 3.
is raised vertically and perpendicularly to the abutment piece 6.
Note that the pressing tool 11 is composed of a linear motion machine such as an air cylinder or a hydraulic cylinder. Therefore, the sleeve frame assembly table 2 has the upper surface of the cap plate e in contact with the contact piece 6, the triangular joint portion Cb joined to the front frame A facing outward, and the other end in contact with the side contact surface 13. While placing the balusters in contact with each other, the balusters g are fitted into positioning pieces 17, 17 provided on the upper surface of the base plate 5, respectively, and the lower wood f is placed to face the Kasagi e, after which the pressing tool 11 is extended. By doing so, each baluster g can be press-fitted into the through hole d, and the armrest frame B can be stacked.

Note that the front frame assembly stand 3 has a
The abutting piece 22 is erected in alignment with the abutting piece 6, and the pressing tool 11 is arranged on the other edge, and the width of the base plate 7 is set within the joint Ca of the capping wood a and the lower wood b. The triangular joint portions Ca of the cap wood a and the bottom wood b are aligned with the inner length L1 between the ends, and therefore protrude from the side surfaces of the base plate 7, respectively. Note that positioning pieces 17 for positioning the baluster c are arranged on the base plate 7, and the pressing tool 1
1, it can be assembled in the same way as sleeve frame B.

The side surface of the base plate 7, that is, the side surface 13 is made of Kasagi e,
By setting the height to be the same as the inner length L2 of the lower wood f, and therefore standing the sleeve frame B on the base plate 5 with the cap e and the lower wood f along the side surfaces, the joints Ca, Cb can be adjusted in height to each other, that is, in this embodiment, the base plate 5
The upper surface near the side abutment surface 13 can form a reference portion 4 on which the joint portions Ca and Cb are aligned by placing the sleeve frame B upright. Also, on the side contact surface 13, a contact piece 25 is formed on one end edge, and a contact piece 25 that contacts the sleeve frame B which is raised and placed upright is formed, and a pressing portion 11 is formed on the other end edge.
By providing the sleeve frame B,
When joining the front frame A, the sleeve frame B can be clamped at the correct position.

However, in the handrail assembly device of the present invention, after assembling the sleeve frame B on the sleeve frame assembly table 2 and the front frame A on the front frame assembly table 3, by raising the sleeve frame B onto the reference part 4, The joint parts Ca and Cb can be aligned, welded,
By fixing with screws or the like, an integrated handrail can be assembled easily and efficiently using one device. The device of the present invention is such that the reference portion 4 is formed by sinking downward from the upper surface of the base plate 5, or is formed with a step from the upper surface of the base plate 5, and furthermore, the dimensions of each part are adjustable. Transforms into various forms.

[Effect of idea]

As described above, the handrail assembly device of the present invention can produce many effects such as being able to assemble an integral handrail having a front frame and a armrest frame efficiently and with high precision using one device.
