Description

  The present invention relates to a technique for automatically closing a member that is slid in a horizontal direction while being supported in a vertical posture by a long horizontal member, such as a sliding door, and to reduce the impact of the cutoff. It is.

As a buffer urging device for a door-like member, one for a rotary door is technically almost completed and widely used.
Compared to this, for example, a buffer-type biasing device for a door-like member that moves in parallel, such as a sliding door, has not yet spread.
The reason why the sliding door buffer urging device is technically more difficult than the rotating door buffer urging device is profound. The root is derived from the difference between the Western-style lifestyle that the revolving door belongs to and the Japanese-style lifestyle that the sliding door belongs to.
For example, Western-style bedding is left on the bed, while Japanese-style futons are folded every morning and put into a closet.
Similarly, the floorboard is struck by joists and the revolving door is left attached to the pillar, but in the Japanese-style room, the tatami mat is lifted and the scissors are removed to perform a large cleaning.
Therefore, the buffer urging device for the revolving door can be left unattached, so it is technically easy. However, the sliding door has to cope with the case where it is removed from the sill / duck, so it is extremely difficult.

Although it is not a fitting, a shock absorber for furniture movable parts (Japanese Patent Laid-Open No. 2002-242978) has been proposed.
In this known technology, as shown in FIG. 2 of that publication, a slot is provided to engage and disengage the pinion and the rack, or the friction damper is brought into contact with the holder to frictionally brake. But
It is a device for a drawer as furniture and cannot be applied to a sliding door as a fitting. In particular, there is a problem in durability because the pinion and the rack are engaged and disengaged, or the rotary damper is brought into contact with the holder to cause friction braking, and the braking action is lost when oil is applied to the friction part. Low reliability.

FIG. 1 is a schematic front view of an extracted main part of an embodiment of a buffer urging device configured to carry out the buffer urging method according to the present invention. FIG.
The reference numeral 1 indicates a sliding door as a vertical plate member,
Reference numeral 2 is a duck as a long member that guides sliding in the X-axis direction while supporting the sliding door in a vertical posture,
Reference numeral 3 denotes a column as a columnar member that functions as a stopper that limits the sliding stroke of the sliding door 1.

Reference numeral 4 designates a base member of the device of the present invention, to which a slide rail 5 in the X-axis direction is fixed.
A slider 6 is guided by the slide rail so as to be slidable in the X-axis direction, and a rack gear 7 is fixed to the slider.
The slider 6 and the rack gear 7 fixed to the slider 6 are urged by a tension spring 8 in the X-axis direction, to the right in the drawing, that is, in a direction away from the column 3.

A pinion gear 9 that meshes with the rack gear 7 is pivotally supported by the base member 4 and has a one-way damper 10 attached thereto. As a result, the pinion gear 9 is at a low position with respect to the base member 4, and the rack gear 7 exerts a damper function by resisting the movement in the left direction of the drawing, that is, in the direction approaching the column 3. Yes.
When practicing the present invention, it is preferable to use a one-way damper described in JP-A-11-132276. If this one-way damper is applied, the sliding door is closed without the need to engage and disengage the pinion and the rack as in the known “furniture moving part shock absorber” (Japanese Patent Laid-Open No. 2002-242978). Only when the damper function is exerted, it is possible not to exert resistance when the sliding door is opened.

A pivot shaft 11 is fixed to the slider 6 (may be fixed to the rack gear 7).
A catch hook 12 is pivotally supported by the pivot shaft 11 so as to swing freely.
In the present invention, the catch hook means “α. When it collides with a mating member, it engages with the mating member, β. It has a function of maintaining the engaged state, and γ. An instrument that is released when engaged.
The “mate member to be engaged by receiving a collision” in the catch hook 12 of this example is an engagement pin 14 in the Y-axis direction attached to the Kamoi 2, and a notch groove 13 for engaging with this is formed. ing.

The arrangement position of the engagement pin 14 is determined as follows.
When the sliding door 1 is moved to the left (in the closing direction) from the state shown in the drawing and the distance D between the sliding door and the pillar 3 reaches a predetermined value (10 cm in this example), the catch hook notch groove 13 edges come into contact with the engaging pin 14.
A locking pin 15 in the Y-axis direction is attached as a mechanism for maintaining the engaged state, and a locking edge 16 is formed on the base member 4 correspondingly.
The locking edge 16 has a shape along a virtual circle s centered on the pivot shaft 11. Details of the engagement state holding mechanism constituted by these members will be described later with reference to FIGS. 2 and 3.

2A and 2B are views for explaining the structure and function of the catch hook, in which FIG. 2A is a schematic front view depicting an operation of engaging with an engagement pin which is a counterpart member, and FIG. A schematic front view depicting the operation of releasing the engagement with the mating member, (C) is a schematic front view depicting a state in which the slide in the X-axis direction is locked, and (D) is the X-axis direction. It is the typical front view on which the state where the slide latching was canceled was drawn.
As mentioned earlier, catch hooks
α. When it collides with the mating member, it engages with the mating member,
β. It has a function to maintain the engagement state,
γ. An instrument that is disengaged when a predetermined condition is satisfied.
Since the catch hook of this example is designed to exhibit these three functions of α, β, and γ, for convenience of explanation, “interaction between the catch hook 12 and the engagement pin 14” and “catch [Interaction between hook 12 and locking edge 16]

(See FIG. 2 (A)), the catch hook 12 drawn with a solid line is a state where the engagement pin 14 is caught, and a state where the engagement pin 14 is released is indicated with a chain line. Although the engagement pin 14 is a stationary member, the engagement pin 14 is depicted so as to be relatively close to the catch hook 12 for easy understanding.
When the catch hook 12 moves as indicated by the arrow c and the engagement pin 14 of the chain line collides with the chain line catch hook 12 as indicated by the arrow c ′, the catch hook 12 swings and swings as indicated by the arrow r. The posture becomes a solid line, and the engaging pin 14 (solid line) is caught.

(See FIG. 2 (B)), the catch hook 12 drawn with a chain line is in a state of catching the engagement pin 14 (chain line). From this state, the catch hook 12 moves in the direction of arrow o,
When the engagement pin 14 moves relatively as indicated by an arrow o ', the catch hook 12 swings and swings as indicated by an arrow l to take a solid line posture and releases the engagement pin 14 (solid line).
Since the engaging pin 14 is fixed to the duck (member 2 in FIG. 1), the catch hook 12 is restrained from moving in the left-right direction with respect to the duck 2 in the catch state of FIG. ing.
In the released state of FIG. 2B, the catch hook 12 can move in the left-right direction with respect to the Kamoi 2.

When the catch hook 12 rotates in the direction of the arrow l to the solid line posture of FIG. 2 (B), the locking pin 15 attached to the catch hook and the locking edge (constituting part 16 in FIG. 1) The relationship is as shown in FIG.
That is, the locking pin 15 is engaged with the locking edge 16 so that the catch hook 12 is locked so as not to move to the right in the drawing together with the slider 6.
When the catch hook 12 is in the catch posture of FIG. 2 (A), the lock pin 15 is detached from the lock edge 16 as shown in FIG. 2 (D), and the movement lock of the catch hook 12 to the right is released. Is done. In the state of FIG. (D), the catch hook 12 can move to the left, but it should be noted that the counterclockwise rotation (counterclockwise) is prevented as indicated by the arrow l (details are shown in the figure). 3 will be described later).

FIG. 3 is a diagram for explaining the operation of the embodiment shown in FIG. 1, and (A) is a schematic diagram illustrating a state in which the sliding door is opened and neither the buffer function nor the biasing function is expressed. The main part front view, (C) is a schematic main part front view depicting a state in which the sliding door is almost closed and the buffer function and the urging function are expressed, and (B) is a reversible state of both the above states. It is a typical principal part front view showing the state currently switched.
Next, the effects of the present embodiment will be described referring mainly to FIG. 3 and looking back on what has been described in FIG.

(Refer to FIG. 3 (A)), the sliding door 1 is pulled to the right in the figure and is opened widely, and the catch hook 12 is swung in the counterclockwise direction (counterclockwise). That is, the relationship with respect to the engagement pin 14 is the release state of FIG. 2B, and the state with respect to the engagement pin 15 is the engagement state of FIG. For this reason, the tension spring 8 is held in the stretched state, and the member provided by applying the present invention ceases its function.
That is, until the sliding door 1 is moved to the left from the state shown in the drawing and the catch hook 12 collides with 14, the sliding door 1 can be moved freely without receiving any special acting force.

When the sliding door 1 is moved to the left from the above state and the catch hook 12 collides with the engagement pin 14 and catches it, the catch hook swings clockwise (clockwise) as shown in FIG. Rotate.
Thereby, in the relationship with the engagement pin 14, the catch state shown in FIG. 2A is obtained, and the lock pin 15 is detached from the lock edge 16.
In FIG. 3A, the tension spring 8 that has not been contracted by the stretched scissors starts to contract when the locking pin 15 is removed as shown in FIG. 3B.

Considering the state of this (B) figure,
One end of the tension spring 8 is attached to the sliding door 1, and the other end is attached to the dug 2 via a slider 6, a catch hook 12, and an engagement pin 14.
For this reason, when the tension spring 8 that has been stretched contracts, the sliding door 1 is driven to the left in the figure, and the sliding door 1 is closed as shown in FIG. In this case, since the urging force of the tension spring 8 is effective, no gap is left between the sliding door and the column 3.
3B to 3C, the locking pin 15 is detached from the locking edge 16 and is guided by the upper edge 18 of the base member 4 in the X-axis direction. (C) As can be easily understood from the drawing, the catch hook 12 cannot rotate counterclockwise (counterclockwise) in this state.

Considered in the above paragraph 0038 is a case where the sliding door 1 is relatively carefully closed by manual operation, but if it is closed with a violently strong force, this figure (B) to (C) In the meantime, a buffering effect is exhibited as follows.
Since the catch hook 12 is locked relative to the head 2 in the left-right direction, the rack gear 7 cannot move left and right with respect to the head 2 accordingly.
For this reason, the rack gear 7 slides to the right relative to the sliding door 1 (guided by the slide rail together with the slider 6), and rotates the pinion gear 9. At this time, the unidirectional damper 10 provides resistance and exhibits a buffer function.

When the sliding door is opened from the state where the sliding door 1 is closed as shown in FIG. 3 (C), the state is changed to the state of (A) through (B) in the opposite process to the above. The direction damper 10 does not give resistance to the opening operation.
However, the manual operator feels that the force for extending the tension spring 8 is heavier than when the device of the present invention is not provided.
In the state of FIG. 3 (A), the tension spring 8 is a stretched hook. That is, energy for energizing the closing and closing is conserved.
Considering all these actions, the heavy thing when opening the sliding door is that it does not cause a wasteful loss of force, it stores energy in preparation for the closing operation, and the energy efficiency of manual operation Is not bad.
Note that the engaging pin 14 and the locking pin 15 in the present embodiment are both pins in the Y-axis direction, but are not necessarily limited to being pin-shaped, as can be understood from the operational effects described above. However, even a member that is mechanistically equivalent is within the technical scope of the present invention.

FIG. 4 is a schematic front view of an embodiment different from FIG. 1 described above.
The points different from FIG. 1 are extracted and summarized as follows.
The tension spring 8 in FIG. 1 has a role of urging the slider 6 and the rack gear 7 to the right in the drawing.
In FIG. 4, a spiral spring 17 is provided instead of the tension spring 8. This spiral spring urges the pinion gear 9 counterclockwise (counterclockwise) in the drawing. Even if configured in this way, the same operational effects as in FIG. 1 can be obtained, and as can be easily understood from the drawing, the external dimensions in the X-axis direction of the buffer urging device can be shortened, and It is easy to keep the spring member lubricated.

The figure which added the orthogonal coordinate axis and the dimension symbol to the typical external appearance front view which extracted and drew the principal part in one Embodiment of the buffer biasing apparatus comprised in order to implement the buffer biasing method which concerns on this invention. It is shown in order to explain the structure and function of a catch hook, wherein (A) is a schematic front view depicting an operation of engaging with an engaging pin that is a mating member, and (B) is a diagram of the mating member.
