Description

[Detailed description of the invention] This invention relates to a protective forming member that is attached to the periphery of a board used in furniture, fittings, etc. In particular, the core material and cover member that make up the forming member are provided separately, and the core material Since the core material is made of hard and semi-hard plastic and the cover member is made of soft plastic, there is no need to manufacture a new core material even if the thickness of the plate material or the design of the forming member differs, and it is sufficient to manufacture only the cover member. , can be obtained cheaply,
In addition, the core material can be easily and reliably attached to the curved edges of the board, and can be processed beautifully.
That is, tooth-like parts 4, 4 are formed on both sides of the leg 3 which is inserted into the linear groove 2 provided on the periphery of the plate 1, and the toothed part 4 is engaged with the leg 3 at a distance l from the insertion part 3' of the leg 3. The band plates 5 are provided orthogonally in a T-shape, and the leg strips 3 and the locking band plate 5 are integrally formed with a core material a made of hard plastic, and a curved groove continuous to the groove 2. 2', and a locking band plate 12 is provided perpendicularly in a T-shape from the fitting part 11' of the short leg 11 at a distance 1.
1. A core material b in which the locking strip plate 12 is integrally formed with semi-hard plastic, and a strip 6 having a U-shaped cross section.
It consists of a cover member c integrally formed of soft plastic with an inward locking strip 7 which is fitted into the space l from both ends of the cover member c.

BACKGROUND ART Conventionally, grooves have been bored into the periphery of plates of furniture and fittings, such as the tops of desks and tables, and edge forming members having a T-shaped cross section have been attached to the grooves to cover the periphery. However, in conventional examples, the leg strips and cover strip plate constituting the edge forming member are integrally formed of soft plastic, or the leg strips are made of hard plastic and the cover strip plate is made of soft plastic. In order to integrally form the leg strips and the cover strip, a mold is made for the entire edge forming member each time the thickness of the plate material changes or the design of the cover strip changes.
Many types of edge forming members must be manufactured, which is expensive. Furthermore, if the leg is made of soft plastic, it will be difficult to attach it to the groove, and there is a risk that it will shrink due to changes in temperature and come off the groove. In addition, the peripheral edge of the plate material has not only straight parts but also curved parts such as corners. It bends, and the relevant part has to be cut out, which takes time and effort during installation, wastes material, and has low strength.Furthermore, among the conventional examples, the legs are made of hard plastic, which are difficult to bend. Additionally, it is easy to come off after installation and cannot be disposed of neatly.

This invention solves these disadvantages, and the structure of an embodiment will be explained in detail next. The example is a core material a integrally formed of hard vinyl chloride.
, a core material b that is separate from the core material a and integrally formed of semi-hard vinyl chloride, and a cover member c that is separate from the core materials a and b and integrally formed of soft vinyl chloride. Consisting of core material a
Forms a locking band plate 5 perpendicular to the upper edge of the leg 3 in a T-shape, and the leg 3 has a fitting part 3' and a protruding part 3'' that fit into a groove 2 bored around the plate 1. toothed parts 4, 4 are formed on both sides of the fitting part 3', an outward flange 8 is formed between the fitting part 3' and the protruding part 3'', and the locking strip plate 5 is Downward stripes 5', 5' are formed on both side edges.
Note that a gap 1 is formed between the fitting portion 3' and the locking band plate 5. In addition, the core material b forms a locking band plate 12 that is orthogonal to the upper edge of the short leg strip 11 in a T-shape, and
has a fitting part 11' that fits into a concave groove 2' bored into a corner curved part of the plate material 1, and a thick protruding part 11'', and has downward stripes 12' on both side edges of the locking strip plate 12. ,1
2' is formed. In addition, the fitting part 11' and the locking band plate 12
A spacing l is formed between them. On the other hand, cover member c
The strip 6 is formed to have a U-shaped cross section, and approximately C-shaped grooves 9, 9 are formed at the corners, and the inward direction is inserted from the lower ends of the side plates 6a, 6a into the space l between the core materials a, b. It forms a claw strip 7' that engages the locking strips 7, 7 and each downward strip 5', 12'.

Next, to explain how to use this example, the plate material 1
The fitting part 3' is fitted into the groove 2 previously bored around the periphery of the plate. At this time, the toothed portions 4, 4 engage with the inner wall of the groove 2, and the outward flange 8 engages with the opening of the groove 2, thereby fixing the core material a. Subsequently, the core material b is bent and the fitting portion 11' is inserted into the groove 2'. After that, the inward locking strips 7, 7 of the cover member c are attached to the core members a,
b, and lock each claw strip 7' to the downward strip 5', 12', and the strip 6 locks the locking strip plates 5, 12, the downward strip 5', 5', It covers the outward facing surfaces of the plates 12' and 12', and also brings the back surface of each inward locking strip 7 into contact with the peripheral edge of the plate material 1.

When using plate material 1 with different thicknesses,
It is sufficient to leave the core materials a and b as they are and use a cover member c made to have the same length and width to match the thickness of the board material 1.For example, it is preferable to use a cover member c with a kamaboko-shaped design. In this case, it is sufficient to leave the core members a and b as they are and change only the cover member c.

In this way, this invention manufactures the core material and the cover member separately, so even if the thickness of the plate material or the design of the forming member is different, it is sufficient to manufacture only the cover member, which is inexpensive, and also allows for straight line The core material that is attached to the shaped groove is made of hard plastic, and the core material that is attached to the curved groove is made of semi-hard plastic, allowing for stable and reliable installation.Since the cover member is made of soft plastic, It has great cushioning properties, is easy to fit into the core material, and can safely relieve pressure from the outside.Furthermore, the hard plastic core material has leg strips with teeth, making it easier to fit into the board material. It can be installed securely, and short legs are formed on the semi-hard plastic core material, so it can be bent easily and without waste, and it can be installed easily and quickly without the need for cutting. It also has some elasticity, so it is difficult to come off after installation.Furthermore, since both core members are provided with locking strips, they have great strength and are easy to attach the cover member, and the gap between the insertion part of the leg and the locking strip can be adjusted. Since the inward locking strip is formed so as to fit therein, the degree of engagement of the cover member is increased and the cushioning property is also increased.

Note that when a substantially C-shaped groove is formed in the cover member as in the embodiment, the inward locking strip can be easily opened and closed, and the inward locking strip can be easily fitted into the core material.
