Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention particularly relates to a device for attaching a drawer or the like to a slide rail attached to a furniture body.

<Prior Art and Problems> Conventionally, in the above device, a drawer engaging member made of a synthetic resin material is attached to the outer rail constituting the slide rail, and the engaging hole of the drawer is engaged with the drawer engaging member. I was ready to install it.

The drawer engaging member includes a mounting portion connected to the outer rail and a locking protrusion that engages with the drawer,
The mounting part includes a rising stop piece that has a front-to-back width larger than the through hole formed in the outer rail and whose upper part is curved to match the inner surface shape of the upper bent piece of the outer rail, and a lower end center of the rising stop piece. It is composed of a mounting protrusion that protrudes downward and has an outward protrusion, and the locking protrusion is connected above the mounting part and is formed into a downward U-shape with appropriate elasticity. It is pushed upward from the bottom of the through hole in the upper bent piece of the outer rail, and once it contracts against elasticity, it protrudes outward from the upper bent piece and returns to its original state due to elasticity. It was configured to do this.

In a state where the locking protrusion protrudes upward from the outer rail, the rising stopper piece is in contact with the inner surface of the upper bent piece, and then the mounting protrusion faces the inner surface of the mounting hole formed in the outer rail. The outward protruding piece of the piece was pushed into the mounting hole to attach the drawer engaging member to the outer rail. (Utility Model Application No. 57-186547) For this reason, it is necessary to form a mounting hole in the board of the outer rail in which the outward protruding piece engages, and also, the outward protruding piece is located outwardly of the board of the outer rail. If it protrudes, it will interfere with the attachment of the outside rail to the drawer, etc., and therefore a mounting hole must be made at a location where a part of the board is raised in the direction of the inside rail, leading to an increase in costs.

Also, in order to use the slide rail for both the left and right sides, the mounting hole must be formed in the center of the board in the vertical direction;
The vertical dimension of the attachment part of the drawer engaging member is inevitably small, and this small attachment part must be operated with fingertips to attach it from the inner surface of the outer rail, making the installation work difficult. There were also problems such as falling and losing powder during installation work.

Furthermore, if the drawer is installed in a hurry and the drawer is mistakenly placed on the locking protrusion, the locking protrusion will be forcibly moved downward, causing the mounting protrusion to curve inward.
There were drawbacks such as the engagement between the mounting hole and the outward protruding piece being disengaged, causing the drawer engaging member to fall, or the mounting protruding piece being bent and damaged.

《Purpose of the present invention》 The present invention improves the above-mentioned drawbacks, has a simple structure, makes it easy to install the drawer engaging member, does not cause looseness in the installed state, and does not have the possibility of easily coming off. The purpose of the present invention is to provide a mounting device for a drawer, etc. on a slide rail that does not have a drawer.

<<Example>> The present invention will be described below based on the drawings. 1
is the outside rail, 2 is the inside rail, 3 is the ball, 4
is a ball holding member, and the slide rail A is composed of the above members.

5 is a drawer engaging member, and 6 is a drawer engaging portion.

The outer rail 1 is formed of a band-shaped metal plate and has a substantially U-shaped cross section, consisting of a base plate 11 and upper and lower bent edges 12, 12, and the upper and lower bent edges 12, 12 are inwardly shaped in an arc-shaped or V-shaped cross section. The ball guide grooves 13, 13 are formed in the longitudinal direction of the curved inner surface, and the rear portions of the upper and lower bent edges 12, 12 are raised to form locking claws 14, 14 that open forward. Upper and lower mounting holes 15, 15 are provided in the portion.

Further, an inner rail stopper 16 is bent inwardly at the front end of the board 11, and a ball holding member 16 is bent inwardly at the rear end, and is protruded from the inner surface at the front end of the board 11. Stoppers 17 and 18 are provided to restrict the range of movement of 4.

10 is a driver insertion hole for attaching the inner rail 2 to the furniture body B, and 101 is a buffer material attached to the inner rail stopper 16.

On the other hand, the inner rail 2 is formed of a band-shaped metal plate and has a substrate 21 of a size that can be inserted into the outer rail 1, and has a substantially U-shaped cross section consisting of upper and lower bent edges 22, 22. 22 is curved outward to have an arcuate or V-shaped cross section, and ball guide grooves 23, 23 are formed on the inner surface thereof along the longitudinal direction.

Further, the board 21 is provided with mounting holes 24 for the furniture body B at several locations in the longitudinal direction.

A stopper 26 is formed at the front end of the base plate 21 of the inner rail 2 and is bent inward.

The ball holding member 4 is a band-shaped metal plate of a size that can be inserted between the outer rail 1 and the inner rail 2, and has a length of about half the length of both rails 1 and 2.
It consists of a substrate 41 and upper and lower bent edges 42, 42, the center portion of the substrate 41 is bent into a U-shape and protrudes inward, and a cushioning material 43 is attached to one end.

Balls 3 are rotatably held at several locations in the longitudinal direction of the upper and lower bent edges 42, 42, respectively, with the balls 3 protruding upward and downward.

In addition, in the drawing, the upper and lower bent edges 4 of the ball holding member 4
2 and 42 have a shape that is connected in front and back,
In order to reduce the weight, the shape may be such that the portion other than the portion that holds the ball 3 is cut off.

The drawer engaging member 5 is molded from synthetic resin, has appropriate elasticity at the upper part, and has a vertical piece 51 that projects upward from the upper bent edge 12 when attached to the outer rail 1, and the vertical piece. a locking protrusion 53 consisting of an inclined piece 52 that slopes downward and inward from the upper end of 51;
It consists of a mounting portion 54 connected to the vertical piece 51.

The mounting portion 54 is located and attached to the inner surface of the outer rail 1, has a larger longitudinal width than the locking protrusion 53, and has an inner fitting projection in the center that fits into the upper mounting hole 15 formed in the outer rail 1. 551 and whose upper surfaces at the left and right ends match the inner surface shape of the upper bent edges 12, 12 of the outer rail 1; A fitting protrusion 56 that fits into the lower mounting hole 15 of the rail 1
and a lower surface of the left and right end portions matching the inner surface shape of the lower bent edge 12; The elastic attachment portion 58 has a substantially U-shaped cross section.

A drawer engaging portion 521 is formed at the lower end of the inclined piece 52 of the locking protrusion 53.

The front and rear width of the locking protrusion 53 is the width of the outer rail 1.
The left and right widths are larger than the upper and lower mounting holes 15, respectively.

The drawer engaging part 6 has a substantially L-shaped cross section and is composed of a drawer mounting piece 61 and a drawer mounting piece 62 connected to the drawer mounting piece 61, and is attached to the side surface of the drawer C.
integrated with.

The end of the drawer placement piece 62 on the furniture body B side is curved to match the outer surface shape of the upper bent piece 12 of the outer rail 1, and the front end is provided with an upper mounting hole 15 of the outer rail 1. An engagement hole 63 is formed in alignment.

The front and rear end surfaces of the engagement hole 63 are each bent upward to form a locking protrusion contact portion 64 .

The distance between the locking protrusion abutting portions 64, 64 corresponds to the longitudinal width of the locking protrusion 53.

Reference numeral 65 denotes a holding protrusion in which a part of the drawer attachment piece 61 is made to protrude toward the furniture body B side at a position where the upper part of the locking protrusion piece 53 is sandwiched.

In addition, the engagement hole 63 and the clamping protrusion 65 are connected to the drawer mounting piece 6.
The reason why the drawer engaging portions 6 are formed before and after the drawer engaging portions 2 is to allow the drawer engaging portions 6 to be used for both the left and right sides.

In this embodiment, the engaging hole 63 and the clamping protrusion 65 are formed in the drawer engaging portion 6, but it goes without saying that they may be formed directly in the drawer C.

When attaching the drawer engaging member 54 and the drawer C to the slide rail A configured as described above, the drawer mounting piece 61 is screwed to the side surface of the drawer C in advance, and the drawer is attached so that the engagement hole 63 is located at the front. C and the drawer engaging portion 6 are integrated.

Next, the outer rail of the slide rail A with the inner rail screwed to the furniture body B is pulled out forward.

At this time, the ball holding member 4 moves forward by a distance that is half the distance that the outer rail 1 moves, and the front end of the ball holding member 4 finally collides with the inner surface of the stopper 26 of the inner rail 2. At the same time, the stopper 17 of the outer rail 1 collides with the rear end of the ball holding member 4, the movement of the outer rail 1 is stopped, and the slide rail A reaches its maximum extension state.

In this state, the locking protrusion 53 of the drawer engaging member 5 is inserted from the inner surface of the outer rail 1 upwardly from below into the upper mounting hole 15 formed in the upper bent edge 12.

At this time, the inclined piece 52 of the locking protrusion 53 moves once towards the vertical piece 51 side due to its elasticity, and the rising stopper piece 55
returns to its original state while contacting the inner surface of the upper bent piece 12, and the inner fitting protrusion 551 fits into the upper mounting hole 15.

Next, the elastic attachment part 58 of the attachment part 54 is deformed into an arched shape toward the furniture body B, and the stopper piece 57 is positioned on the inner surface of the lower bent edge 12 of the outer rail 1, and the elastic attachment is performed. When the arched state of the portion 58 is released and the fitting protrusion 56 is fitted into the lower mounting hole 15, the drawer engaging member 5 is prevented from shifting on the outer rail 1 due to the elasticity of the elastic mounting portion 58. Can be attached.

Next, attach the rear end of the drawer mounting piece 62 of the drawer engaging portion 6 provided on the drawer C to the bent edge 12 of the outer rail 1.
Place it on the upper rear surface of the drawer C and push it backward to engage the rear end of the drawer mounting piece 62 with the locking pawl 14.
prevent the rear part from lifting up.

Next, when the front end of the drawer C is pushed downward, the locking protrusion 53 protruding above the outer rail 1
The inclined piece 52 is located in the engagement hole 63 of the drawer mounting piece 62, and once moves toward the drawer C side against the elasticity and then protrudes outside the engagement hole 63. The original state is restored, and the drawer locking portion 521 provided at the lower end of the inclined piece 52 engages with the end surface of the engagement hole 63 on the furniture body B side.

This prevents the front end of the drawer C from floating upwards unexpectedly.

Next, when removing drawer C from the above state,
It is preferable to push the inclined piece 52 of the locking protrusion 53 toward the drawer C side and lift the drawer C with the drawer locking part 521 positioned in the engagement hole 63.

In this embodiment, a concave groove is provided at the lower end of the inclined piece 52 of the locking protrusion 53 to form the drawer locking part 521.
It may be set to 1.

In addition, the slide rail A is simply composed of a pair of outer rails 1 and inner rails 2, but in order to increase the amount of drawer that can be drawn out, the slide rails A may be of a type in which the inner rails 2 are joined back to back, or in which the inner rails are joined at the top and bottom. It is also possible to use it for rails as appropriate.

<<Effects>> As described above, in the present invention, the mounting portion of the drawer engaging member is formed to be larger than the up stop piece, the down stop piece, and the elastic mounting portion to the extent that it is comparable to the vertical dimension of the outer rail. Sometimes, it is easy to work by picking it up with your fingertips, and there is no fear of it falling off.

Furthermore, the up stop piece and the down stop piece are formed with internal fitting protrusions that fit into the upper and lower mounting holes, and fitting protrusions, so that the upper and lower surfaces of the left and right ends match the inner shape of the upper and lower bent edges. There is no fear that the drawer engaging member will shift or wobble in the front, rear, left, or right directions when the drawer is inserted or removed.

Furthermore, since an elastic attachment part is formed between the up stop piece and the down stop piece, even if the drawer is accidentally placed on the locking protrusion, even if the elastic attachment part is arched, the elasticity will always keep the drawer in place. Since it abuts the bottom surface from below, when the bottom surface of the drawer is in contact with the outer surface of the upper bent edge of the outer rail, the upper end of the locking piece is located in the upper mounting hole, and the drawer engaging member is in contact with the outer rail. There is no fear of it coming off, and when the drawer is removed from above the locking protrusion, the locking protrusion will protrude upward from the upper mounting hole due to the elasticity of the elastic mounting part, and the inner fitting projection will fit into the upper mounting hole. , the drawer engaging member is reattached to the outer rail.

Moreover, compared to the conventional method, the present invention has a simpler structure, which only requires forming upper and lower mounting holes on the outer rail.
It can be manufactured at low cost and does not affect the strength of the outer rail.
