Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a guide device for a sliding door of furniture or the like.

[Conventional technology]

As a guide device used for furniture such as a closet equipped with a sliding door, a roller is housed in a case that configures the guide device so that the roller can be retracted and retracted. It has been known from the past that the roller is projected into the upper rail by immersing it inside and locking it inside the case, and unlocking it with the door positioned below the upper rail. (See Japanese Utility Model Publication No. 63-44977).

The guide device, on the appearance of the door, because it is installed in two places on the left and right along the upper edge of the back surface of the door, when fitting the door, turn the hand on the back surface of the door, search for the operation button with that hand, The lock is released by sliding the operation button horizontally.

[Problems to be solved by the device]

However, the guide device is inconvenient because the operation button cannot be seen with the eyes because it is attached to the back surface of the door, and the user has to manually operate it.
Therefore, it is desirable that the operation of the operation button is as simple as possible.

Then, the subject of this invention is to provide the guide tool for fittings which can be what is called a push system, in order to further simplify the operation of the said operation button.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention accommodates a roller support body to which a roller is attached so as to be movable up and down in a case with an open upper surface, and imparts an upward elastic force to the roller support body. The vertical movement range is limited to the range where the roller appears above and below the case, and the operation button of the operation member inserted slidably in the front-back direction along the inner surface of the case is exposed on the front plate of the case and at the rear end of the case. The formed engaging claws are opposed to the engaging recesses formed on the back surface of the roller support, and the elastic piece provided on the inner surface of the case back plate is pressed against the engaging claw back surface of the operating member to engage the engaging claws. That is, the structure that is engaged with the recess is adopted.

[Action]

When the roller is pushed down, the engaging claw of the operating member engages with the engaging recess of the roller support, and the engaging claw abuts the elastic piece provided on the case back plate, thereby maintaining the above-mentioned engaged state. And the roller is locked in the case.

When the operation button of the operation member is pushed, the operation member retracts against the pressing force of the elastic piece, the above-mentioned engagement claw is disengaged from the engagement recess, and the lock is released. When the lock is released, the roller support moves upward, and the roller projects from the upper end of the case.

〔Example〕

As shown in FIG. 1, the guide device of the embodiment is composed of a case body 1, a back plate 2, a roller support 3, a roller 4 integral with the roller support 3, an operating member 5, and a coil spring 6. . The back plate 2 on the back of the case body 1
The case 8 whose upper end surface is opened is formed by fitting and fixing with a screw 7.

The outer surface of the side wall 9 of the case body 1 has a U shape as a whole, and a brim 10 is formed around the side wall 9.
A mounting hole 11 is formed in 10.

A vertical guide surface 12 is formed on the inner surfaces of the left and right side walls 9 of the case body 1, and a vertical guide surface 14 is also formed on the lower inner surface of the front plate 13 of the case body 1. The roller support 3 is housed in the case 8 so as to be vertically movable along the guide surfaces 12 and 14 and the inner surface of the back plate 2.

As shown in FIG. 2, the back plate 2 has vertical guide grooves 15 formed therein, and vertical ribs 16 formed on the back surface of the roller support 3 are fitted into the guide grooves 15 to support the rollers. The vertical movement of the body 3 is accurate.
Further, in order to limit the vertical movement range of the roller support 3, the front plate 13 is provided with an elongated hole 17 in the vertical direction, and a projection 18 (see FIG. 3) of the roller support 3 is provided in the elongated hole 17. Upon insertion, the roller support 3 is raised to a height where the protrusion 18 abuts the upper end of the slot 17.

A horizontal groove 19 is formed in the middle of the guide surface 12, and a slot 20 is formed in the front plate 13 of the case body 1 at the same height as the groove 19. These grooves 19
The leg portions 22 on both sides of the operation member 5 are slidably inserted in the front and rear direction. Further, an operation button 23 provided at the front end of the operation member 5 is penetrated through the elongated hole 20 and exposed on the front surface of the front plate 13 (see FIG. 3). The front surface of the front plate 13 is, as shown in FIG.
It is recessed one step to avoid the protrusion of 18.

The roller support 3 has a size such that the upper end surface thereof has the same height as the upper side wall of the groove 19 in the lowest position, and the roller 4 is rotatable on the upper end surface via the shaft 24. Attached to. The height of the roller 4 is formed so that the upper end surface thereof substantially coincides with the upper end surface of the case 8 when the roller support 3 is at the lowest position (see FIG. 3).

Further, on both side surfaces of the roller support body 3, there are provided engaging recesses 25 which are recessed in the rear surface thereof. Further, the coil spring 6 is interposed between the hole 26 formed in the bottom surface and the case main body 1 to apply upward elastic force to the roller support 3.

As shown in FIG. 5, the leg portions 22 of the operation member 5 are along the both side surfaces of the roller support body 3, and the tip portions thereof are bent inward, and the inner surface of the bent portion 28 has the above-mentioned structure. Engaging claws 29 that engage with the engaging recesses 25 are formed.

Further, a downward U-shaped slit 30 is formed on both sides of the guide groove 15 of the back plate 2, and an elastic piece 31 is provided by thinly forming an inner portion of the slit 30. The inner surface of the elastic piece 31 is flush with the inner surface of the back plate 2, and the back surface of the bent portion 28 of the operation member 5 contacts the same. As a result, the engagement claw 29 and the engagement recess 25 are securely engaged with each other, and unless the operation button 23 is pushed against the pressing force of the elastic piece 31, the engagement between the two is not released.

The guide device of the embodiment has the above-mentioned configuration,
As shown in FIG. 5 to FIG. 5, the door 32 is inserted into a recess 33 provided on the back surface of the upper edge of the door 32, and a screw 21 is screwed into the mounting hole 11 of the flange 10 to fix the door 32 to the door 32.

When the door 32 is fitted on the rail 27, as shown in FIG. 3, the roller 4 is pushed in, and the engagement claw 29 of the operation member 21 is engaged with the engagement recess 25 of the roller support body 3 to bring it into the locked state. Keep it.

After correctly positioning the door 32 under the rail 27, rotate the hand on the back surface of the door 32 and push the operation button 23 toward the front surface of the door 32 with your fingertips, and the operation member 21 presses the elastic piece 31. It retreats in opposition to release the above engagement. When the engagement is released, the roller support body 3 projects into the rail 27 above the case 8 by the elasticity of the coil spring 6 (see FIG. 4).
The rise of the roller support 3 is restricted by its projections 18 hitting the upper ends of the slots 17.

[Effect of device]

As described above, according to the present invention, even if the operation button of the guide device attached to the back surface of the door or the like cannot be seen with the eyes, the operation of the operation button is of the push type. It can be performed more easily than the operation of.
