Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a drawer slide rail, which is particularly easy to manufacture and has an increased supporting effect.

[Conventional technology]

Conventional drawer slide rails have two pairs of pull plates and stand plates that fit into each other on both sides of the drawer, as shown in Figure 4, to facilitate the opening and closing of the drawer.The structure of one pair is as follows. As shown in FIG. 5, it includes one standing plate 7 and one pulling plate 8. Since the two sets provided on both sides of the drawer have a mutually symmetrical structure, the following description will explain only one set.

The upright board 7 and the pull board 8 are each cut and press-formed from the same steel plate, and the upright board 7 has a U-shaped cross section, and a pulley 5 is provided at one end of the upright board 7. The pulley 6 of the pulling plate 8 is connected to the U of the standing plate 7.
It rolls within a slide rail formed by a side wall with a cross-section of a letter shape, and the stand plate 7 is fixedly installed inside the desk, and the drawer plate 8 is installed outside the drawer so that they engage with each other. This will allow you to open and close this drawer smoothly.

[The problem that the idea attempts to solve]

In manufacturing such a structure, the upright plate and the pull plate must be cut and then press-formed repeatedly. In other words, each assembled part must undergo the same repeated process. It took a long time to produce.

Furthermore, after it is attached to the drawer, it is necessary to support the drawer with a certain supporting force, but especially when the drawer is opened and the drawer plate and stand plate are fully opened, the receiving force is as shown in Figure 6. Since the points are concentrated on both parts A and B at the mating ends, such conventional slide rails cannot provide effective support and cannot meet the standard load according to international regulations. In order to meet the requirements of the industry, it was necessary to use a thicker steel plate as the base material to obtain the necessary supporting force.

However, the use of a thicker steel plate obviously increases the cost of the product and makes it difficult to form the product, and there are other problems, such as increased weight, which increases shipping costs.

Therefore, the main purpose of the present invention is to make the upright plate and pull plate of the slide rail assembleable, thereby making mass production possible and reducing the labor required. The purpose of this is to increase the supporting force and strength by engaging the upright plate and the pull plate with each other, thereby reducing the cost of materials.

Another object of the present invention is to provide a prefabricated drawer slide rail consisting of a rail part and a mating part, which can be quickly formed by forming the rail part in one drawing process. This technology is useful for mass production, enables the fitting part to be manufactured by press molding, enables mass press molding, and allows rapid assembly by combining these clever shapes. It has economic value that leads to increased production and cost reduction.

[Means to solve the problem]

A standing plate fitting part 1 is provided with one pulley 5 at the tip of the plate piece and formed as a hook-shaped part by bending the upper and lower edges of the end parts, respectively, and the above-mentioned hook-shaped part of this standing plate fitting part fits together. A fitting groove 21 and an arc-shaped engagement edge 22 extending from the fitting groove 21 are created independently of the upright plate rail portions 2 provided on the upper and lower edges, respectively.

After fitting the hook portions provided on the upper and lower edges of the upright plate fitting portion with the fitting grooves provided on the upper and lower edges of the upright plate rail portion, respectively, tighten the upright plate fitting portion with screws or rivets. A standing board set is constructed by fixing the board and the standing board rail part.

On the other hand, a pulley 6 is provided at the tip of the plate piece, and a puller plate fitting part 3 is formed in which upper and lower edges 32 and 33 of the distal end are respectively formed as hook-shaped parts, and a hook-shaped part is provided at the upper edge of this puller plate fitting part. V-shaped groove 4 into which the part fits
1 and an arcuate engaging edge 42 extending from the engaging edge 42 on the upper edge, and an engaging portion 43 on the lower edge that engages with a hook-shaped portion provided on the lower edge of the pulling plate fitting portion. They are created independently from the plate rail part 4.

Then, the hook part provided on the upper edge of the pulling plate fitting part and the V-shaped groove of the pulling plate rail part are fitted together, and the hook part provided on the lower edge of the pulling plate fitting part and the pulling plate rail. After fitting the engaging grooves of the parts, the pulling plate fitting part and the pulling plate rail part are fixed together with screws or rivets to form a pulling plate set.

After fixing the thus obtained standing board set to a desk or the like and fixing the pulling board set to a drawer, the pulley 5 of the standing board set engages with the pulling board rail part of the pulling board set and is pulled out. By assembling the pulley 6 of the board set so as to engage with the drawer rail portion of the upright board set, the drawer can be moved in and out smoothly and a sufficient supporting force can be provided.

The upright plate rail part 2, which is formed independently of the upright plate fitting part 1, has the same cross section over its entire length, so it can be drawn and molded. A fitting groove 21 into which the shaped portion is tightly fitted, and an arcuate engaging edge 22 extending from the fitting groove 21 and functioning as a rail on which the pulley of the pull plate set moves are provided on the upper and lower edges, respectively.

After fitting the hook-shaped part of the upright plate fitting part 1 into the fitting groove 21 of the upright plate rail part 2, the two are connected by screwing or riveting, for example, to form the part shown in FIG. A set of standing boards as shown in and 2 is formed.

FIG. 2 shows the configuration of the pull plate fitting part 3 and the pull plate rail part 4 that make up the pull plate set.
The pulling plate fitting part 3 as a whole is similar to the above-mentioned standing plate fitting part 1.
Although it is substantially plate-shaped in the same manner as in FIG.

A pulley 6 is provided at the front end of the pull plate fitting part 3, and the upper and lower edges extending from the end 31 in the direction of the pulley are bent into a hook shape by, for example, press molding to form hook-shaped parts 32 and 33. has been done.

The pull plate rail part 4, which is formed independently of the pull plate fitting part 3, can be formed to have the same cross section over its entire length, so it can be drawn and molded. , the above-mentioned pull plate fitting part 3
A V-shaped groove 41 in which the hook-shaped part 32 provided on the upper edge is tightly fitted, and a pulley 5 provided at the upright plate fitting part of the upright plate set 1 when this pull plate set moves. An arcuate edge 42 is provided extending from this V-shaped groove 41 and serves as a rail for pressing against the upper side and preventing the front of the drawer from lowering.

A hook-shaped portion 3 provided at the lower edge of the pull plate fitting portion 3 is provided on the lower edge of the pull plate rail portion 4 opposite to this upper edge.
An engaging portion 43 is provided for engaging and supporting 3, and this engaging portion 43 is formed by cutting out a part of a pull plate rail member formed by pultrusion molding using a press or the like. It can be formed by

The pull plate fitting part 3 and the pull plate rail part 4 are constructed by fitting the hook-shaped part 32 provided on the upper edge of the pull plate fitting part 3 into the V-shaped groove 41 of the pull plate rail part 4 and pulling the hook. Pull the hook-shaped part 33 provided at the lower edge of the plate fitting part 3 to the engaging part 4 of the plate rail part 4.

and 4 to form a pull plate set.

This figure 3 shows a combination of a standing plate set consisting of the standing plate fitting part 1 and the standing plate rail part 2, and a pulling plate set consisting of the pulling plate fitting part 3 and the pulling plate rail part 4, as described above. This is the state when the drawer is inserted into a drawer storage part such as a desk, as seen from the drawer side.

When the drawer changes from the illustrated state to the pushed-in state, the drawer plate set 3 attached to the drawer
4 also moves to the right in the figure, and the arcuate edge 42 of the pull plate set slides into the arcuate engagement edge 22 of the upright plate set, so that the engagement edges 22 and the arcuate edge 42 are A contact area is formed between the two, and the contact point between the lower surface of the arcuate edge 42 of the puller plate set and the upper surface of the pulley 5 of the upright plate set is used as a fulcrum, and the upper surface of the arcuate edge 42 of this puller plate set and the upright plate By using the portion that contacts the lower surface of the arcuate engagement edge 22 of the set as a restraint, it is possible to prevent the front of the drawer set, that is, the front of the drawer, from lowering.

Therefore, if the arcuate edge 42 of the drawer plate set slides into the arcuate engagement edge 22 of the upright plate set even when the drawer is opened to the outermost position, this can be avoided. Since the contact surface is a wide contact surface between the arcuate edge 42 of the pull plate set and the arcuate engagement edge 22 of the upright plate set, sufficient support strength can be obtained.

In addition, the force applied to the pulley 5 of the upright plate fitting part 1, which serves as a fulcrum, is distributed over the entire fitting part between the hook-shaped part of the upright plate fitting part 1 and the fitting groove 21 of the upright plate rail part 2, and , the force that the arcuate edge 42 of the puller plate rail portion 4 of the puller plate set receives from the pulley 5 is transferred from the engaging portion 43 to the hook-shaped portion 33 at the lower edge of the puller plate fitting portion 3.
The upright board set and the pull board set have high strength.

As a result, there is no need to increase the strength by increasing the thickness of the main body structure, and according to experiments, the conventional structure can only satisfy the standard load with a thickness of 1.5 mm, but with the present invention, the standard load can be satisfied only with a thickness of 1.5 mm. For example, it is possible to meet the requirements with a thickness of 0.8 to 1.2 mm, which is clearly an effect that cannot be achieved with conventional structures.

What has been described above is one preferred embodiment of the present invention, and all variations or modifications thereof fall within the scope of the utility model registration claims of the present invention.

[Effect of idea]

According to the present invention, mass production is possible by assembling the upright plate and the pulling plate of the slide rail, and labor is reduced, and the cross-sectional shape of the rail portion is arcuate, so that the upright plate and the pulling plate can be assembled. By engaging with each other, special effects can be achieved which increase the bearing capacity and increase the strength, thereby reducing the cost of the material.

Another advantage of the present invention is that the rails of the upright board set and the pull board set can be quickly manufactured individually by pultrusion molding, and the material thus formed can be made into the required length. Since it can be cut into pieces and used, it is very suitable for manufacturing and is also useful for mass production.

In addition, the fitting part of the upright plate set and the pulling plate set can be manufactured independently from the rail part when manufactured by press working, so it can be processed and manufactured quickly. By assembling after manufacturing each, it is possible to form a standing board set and a pulling board set.
This provides economical and practical effects that meet the objective of improving manufacturing efficiency.

Furthermore, not only can it contribute to cost reduction as described above, but also the special effect of reducing transportation costs is achieved because the weight of the product is reduced since there is no need to use thick steel plates.
