The present invention provides, among other things, a sliding door for a pinch prevention device, in particular, by providing it on one of the sliding doors constituting the sliding door, or between the one sliding door and the other sliding door. The present invention relates to a finger pinching prevention tool that prevents a finger from being pinched between opposing wall bodies when in an open position.

For example, a sliding door that consists of two sliding doors that overlaps the other sliding door when one sliding door is opened, or a piece that consists of a single sliding door that overlaps the wall when opening the sliding door In a sliding door, there is a possibility that a finger may be caught in a gap between the sliding door and the sliding door or a gap between the sliding door and the wall surface. Then, the structure which prevents that a finger | toe is pinched in the said clearance gap by attaching to the said sliding door or the said single sliding door is proposed (for example, refer patent document 1 and patent document 2). The structures disclosed in Patent Document 1 and Patent Document 2 are incorporated into a digging type handle in a sliding door. For example, in Patent Document 1, a movable finger hook member that hooks a finger on a pull handle embedded in a sliding door and a stopper member that interlocks with the movement of the finger hook member are provided, and the finger is hooked on the finger hook member. A structure is disclosed in which when the sliding door is pushed in the opening direction, the stopper member protrudes out of the handle and abuts against the end face of the wall body or another sliding door.

A guide groove; a pulling member disposed so as to be freely retractable with respect to the sliding door surface of the casing; and a spring member for urging the pulling member in a direction to be retracted from the sliding door surface of the casing. A structure is disclosed in which when the sliding door is moved, the pulling member protrudes from the sliding door surface against the urging force of the spring member, or can be maintained in the protruding state.

Japanese Patent Application Publication No. 2003-232165 Japanese Patent Application Publication No. 2004-150153

The structure of each of the above patent documents is designed to prevent a finger from being caught by protruding a stopper or a pulling member in conjunction with an operation of opening the sliding door, but has the following problems.
(A) When the sliding door is not opened using the pulling handle, for example, when the sliding door is operated to move in the opening direction by pushing the end face of the sliding door, there is a possibility of pinching the finger.
(B) Since the structure is also used as a pull handle, the installation location in the sliding door is limited, it is easy to stand out, and there is no degree of freedom in external design.
(C) Since the impact of the entire sliding door is received at one place, the hitting sound and impact sound are large, which not only gives a sense of incongruity, but also has the risk of breakage or destruction. In Patent Document 2, it is also considered that a cushioning cushioning material is attached to the abutting surface of the pulling member. However, the cushioning material is likely to be worn or discolored to deteriorate the appearance, and has a stable braking characteristic. It cannot be maintained.

The present invention was developed from the above background. The purpose is to increase the degree of freedom of the sliding door design by making it possible to be installed in any part of the sliding door, to improve the appearance of the sliding door, and to minimize the impact sound. Is to make it.

In order to achieve the above object, the present invention provides a movement assisting device having any of the following features (1) to (8).
(1)
A surface of the sliding door, provided in the sliding door, which prevents the finger from being caught between the other sliding door constituting the sliding door together with the sliding door or a wall body facing the sliding door in the open position. Alternatively, a case embedded in the back surface, a slider disposed so as to be slidable in the same direction as the sliding door with respect to the case, and support so that at least one end side of the slider can protrude from the front surface or the back surface of the sliding door. And a braking means for braking sliding of the slider when the stopper comes into contact with the other sliding door or the wall body by the movement of the sliding door.

The present invention having the above characteristics further preferably has any of the following characteristics (2) to (8).
(2)
The stopper is swung on the slider with a shaft portion as a fulcrum.
(3)
The stopper is biased so as to be able to come into contact with the other sliding door or the end surface of the wall body by the biasing force of the biasing means.

(4)
There is switching means for selectively switching the protruding state of the stopper from the front or back surface of the sliding door and the immersed state of the sliding door.
(5)
The biasing means uses a coil spring.

(6)
The switching means is an engagement mechanism that is provided on the slider and the stopper and includes a concave portion and a convex portion that engage with and disengage from each other.
(7)
The switching means is provided between the slider and the stopper, holds the stopper in a sunk state by a pushing operation in the sunk direction of the stopper, and performs the squeezing operation in the same direction by the stopper. It is a cam latch mechanism that releases the holding and switches to the projecting state.
(8)
The braking means is a piston damper.

The finger pinching prevention device of the present invention has the above feature (1), so that the stopper is in a protruding state in which one end of the stopper protrudes from the front or back surface of the sliding door with respect to the slider, that is, in the standby state, and in the sinking state. It can be switched to the state, that is, the storage state, so that it can be used by switching the stopper between the standby state and the storage state every time the sliding door is opened and closed. It is also possible to use it by the method of switching. Of course, the sliding door can be opened until it is fully opened by switching the stopper to the retracted state.

In the finger pinching prevention tool of the present invention, the stopper is supported by a slider arranged to be slidable with respect to the case, and the slider is slid while being braked by the braking means. For this reason, in this structure, if the sliding door is moved in the opening direction with an excessive force and the stopper is a sliding type by moving the sliding door (a sliding door with a finger pinching prevention device), In the case of one sliding door, the corresponding end face of one sliding door, even if it strongly contacts the corresponding end face of the opposite wall body in the open state, the final full force is generated by the sliding of the slider braked by the braking means. Absorbed during the transition to the stroke state, thereby making it possible to reliably eliminate the possibility of discomfort and damage.
In addition, since the finger pinching prevention device of the present invention is configured as a dedicated finger pinching prevention device including a case, a slider, and a stopper, the member structure and appearance, and the installation location of the sliding door can be freely compared to the conventional structure that also serves as a puller. The degree of operation can be expanded, and the operation is performed independently of the pulling handle, so that it is easy to use and the following additional functions can be easily added.

Further, since the finger pinching prevention device of the present invention has the feature (2) above, the stopper is swung on the slider with the shaft portion as a fulcrum. The protruding dimension can be reduced.

Further, since the finger pinching prevention tool of the present invention has the feature (3) above, the stopper is urged in the protruding direction by the urging means, so that the stopper is manually operated as in the first embodiment. There is no need to switch from the sunken state to the bumped state, thereby improving usability.

In addition, since the finger pinching prevention device of the present invention has the feature (4) described above, the stopper can be selectively switched between a protruding state and a sinking state by the switching means, so that the child's growth, moving, family It is possible to respond immediately to changes in configuration. For example, when the child is small, the stopper is kept in a projecting state so that the finger pinching prevention operation is always obtained.

In addition, since the finger pinching prevention tool of the present invention has the feature (5) above, a coil spring is used as the biasing means, so that the required biasing force can be applied accurately and the design change can be minimized. Can be added to the limit.

In addition, since the finger pinching prevention tool of the present invention has the feature (6) above, an engaging mechanism composed of a concave portion and a convex portion that engage with and disengage from each other is adopted as the switching means, and thus the number of members is increased. And can be implemented easily.

Further, the pinch prevention tool of the present invention has the feature (7) above, so that the stopper is held in the depressed state by the first pushing operation as the switching means, and the holding is released by the next pushing operation. Since the cam latch mechanism (this mechanism is also referred to as a push / push locking mechanism, push / open mechanism, etc.) that switches the lever to the projecting state is adopted, the operability is more excellent than the engagement mechanism.

Moreover, since the pinch prevention tool of the present invention has the above feature (8) and employs a piston damper as a braking means, a mechanism such as a rack and pinion such as a rotary damper is unnecessary, The braking force can be reliably applied while reducing the overall size.

(Example of use)
5 (a) to 6 (c) show an example in which the above-described finger pinching prevention tool 5 is attached to a one-pull type sliding door 8. FIG. Reference numeral 6 denotes a sliding door frame member, and reference numeral 7 denotes a wall body facing the sliding door 8 in an open state. 6a is an upper frame portion, 6b is a vertical frame portion, and 6c is a slide rail or groove provided in the lower frame portion. Although not shown in the figure, the upper frame portion 6a is provided with a slide rail or groove facing the rail or groove 6c. The sliding door 8 is provided on the front surface or the back surface, and has a pulling handle 8a provided at a substantially middle portion on one end side and a finger pinching prevention tool 5 provided on the lower side on one end side. Both the pulling handle 8 a and the finger pinching prevention tool 5 are fitted in a recess provided on the front surface or the back surface of the sliding door 8. Among these, as shown in FIG. 6A, the finger pinching prevention tool 5 is a screw 19 that is inserted from two mounting holes 10 a provided in the mounting plate portion 10 after the case 1 is fitted in the recess. Fixed through. In the fixed state, the mounting plate portion 10 is flush with the front or back surface of the sliding door 8. The wall body 7 substantially overlaps the corresponding end surface of the sliding door 6 when the exposed end surface 7 a is fully opened.

(Operation)
In the finger pinching prevention tool 5 described above, the stopper 3 is rotatably supported in the opening 21 by fitting the shaft portions 35 on both sides into the corresponding shaft holes 25 on the opening side. In this assembled state, as shown in FIGS. 4 (a) and 4 (b), the stopper 3 is in a depressed state (same as the stored state) in which it is entirely accommodated in the opening 21, and FIGS. As shown in FIG. 3B, for example, as shown in the figure, the proximal end side is pushed with a finger or the like, and the shaft portion 35 is turned as a fulcrum to project the distal end side out of the opening 21 and the window 12. It is switched to the collision state (same as the standby state). In this case, the maximum protrusion angle of the stopper 3 is restricted by contacting the inner end surface 23 whose base end surface 34 is an inclined surface on the opening side.

The stopper 3 is manually moved from the collapsed state to the projecting state as shown in FIG. 3 (a) because the stopper 3 is rotated in the horizontal direction in the usage state shown in FIGS. 6 (a) to 6 (d). Even after releasing the pushing force after switching by the above, the projecting state is maintained. This is the same when the stopper 3 is pushed in the direction of the arrow from the protruding state and switched to the depressed state as shown in FIG. 3B.

Further, in this usage example, as shown in FIGS. 3A and 4B, the stopper 3 is moved to the rightmost side as shown in FIGS. 3A and 4B, and FIG. And as shown to Fig.4 (a), it slides, receiving the braking of the braking means 4 to the control position moved to the leftmost side. In the initial position, the rod 41 constituting the braking means 4 protrudes greatly from the cylinder 40.

When the stopper 3 is slid to the initial position in the retracted state as shown in FIG. 4B and then switched to the protruding state shown in FIG. 3A, a standby state in which a finger pinching prevention operation is obtained is obtained. It becomes a state. That is, in the standby state shown in FIG. 3 (a), when the sliding door (not shown) is moved in the opening direction, the stopper 3 has a corresponding end surface of the other sliding door other than the sliding door, In this case, after the sliding door comes into contact with the end surface 7a of the opposing wall body 7 in the open state, the sliding door is slid in the direction of the arrow in FIG. . At that time, while the slider 2 braked by the braking means 4 slides, the collision force received from the wall body 7 or the like is changed from the state shown in FIG. 6A to the final full stroke state shown in FIG. Will be absorbed. For this reason, with this structure, it is possible to reliably prevent pinching of the fingers and to absorb the collision sound with certainty, so there is no possibility of abnormal noise generation and excellent durability.

[Second Embodiment]
As shown in FIG. 7 (a) to FIG. 7 (c), the finger pinching prevention device according to the second embodiment of the present invention is configured such that the stopper 3 is always applied in the protruding state by a coil spring S as a biasing means. This is different from the first embodiment in that the stopper 3 is held in the retracted state or the retracted state by the engaging mechanism including the convex portion 27 and the concave portion 36 that engage and disengage with each other. In the following description, the same members and the same functional parts as those in the first embodiment are denoted by the same reference numerals, and only the changed configuration will be described in detail.

The coil spring S urges the stopper 3 in the projecting direction while being supported by the slider 2. Specifically, the slider 2 is provided with a partition wall 21 b having a predetermined shape between the interior 20 and the opening 21. The shaft 28 protrudes from the partition wall 21b. On the other hand, the lower surface 31 of the stopper 3 is provided with a recess 31a for receiving the tip of the coil spring S. In this structure, the coil spring S is supported by the shaft 28 and incorporated in a state where the spring tip is fitted in the recess 31a, and the stopper 3 is always urged in the projecting direction.

In the above engaging mechanism, the convex portion 27 is provided on the slider 2 and the concave portion 36 is provided on the stopper 3. In other words, the convex portions 27 are provided on the opposing inner surface of the slider-side opening 21. On both side surfaces 32 of the stopper, the concave portion 36 is provided at a position corresponding to the convex portion 27, and a shallow groove-shaped guide portion 36a is provided in front of the concave portion 36. For this reason, as shown in FIG. 7C, when the stopper 3 is pushed in the direction of arrow depression from the protruding state against the urging force of the coil spring S, the convex portion 27 elastically moves from the guide portion 36a to the concave portion 36. Engage and hold the stopper 3 in the submerged state. This holding is released by pressing a depression 30a provided on the base end side of the upper surface 30 of the stopper 3 with a finger or the like. The stopper 3 is switched to the projecting state by the urging force of the coil spring S by the release.

In addition, as the above engaging mechanism, the convex part 27 may be provided in the stopper 3, and the concave part 36 engaged / disengaged with the convex part 27 may be provided in the slider 2. Further, instead of the engagement mechanism constituted by the concave portion 36 and the convex portion 27, the stopper 3 is held in a depressed state by a pressure contact force by a leaf spring provided so as to protrude from the inner surface of the opening 21 of the slider 2. It may be.

[Third Embodiment]
The finger pinching prevention tool according to the third embodiment of the present invention is an example in which the switching means of the second embodiment is changed as shown in FIGS. 8 (a) to 8 (c). This switching means comprises a cam latch mechanism 9 that holds the stopper 3 in the depressed state by the first pushing operation, releases the holding by the next pushing operation, and switches the stopper 3 to the projecting state by the biasing force of the coil spring S. . The cam latch mechanism 9 is a so-called push / push locking mechanism including a cam groove 38 provided in the stopper 3 and a trace pin 45 provided in the slider 2. Here, the trace pin 45 has a shape substantially equal to the alphabet “U”, a base end pivotally supported by a corresponding portion on the outer side surface of the slider 2, and a tip end provided on the side surface of the slider. 29, and is urged by a leaf spring 46 that protrudes into the opening 21 and is attached to the slider outer surface. That is, the leaf spring 46 presses the tip that becomes the trace portion into the opening 21 while the corresponding portion of the trace pin 45 is lightly pressed.

As shown in the enlarged view of FIG. 8A, the cam groove 38 is formed on the corresponding side surface 32 of the slider 2, and the introduction groove a located on the lower surface side, and from the introduction groove a to the left upper surface side. An extended dwelling groove b, a locking guide groove c and a release guiding groove e which are separated on the right and up and down, and a concave locking located slightly to the left between the guiding grooves c and e A groove d and a return groove f extending from the guide groove e to the introduction groove a are formed.

In the cam latch mechanism 9 described above, as shown in FIG. 8B, the trace pin 45 is disengaged from the introduction groove a when the stopper 3 is in a protruding state. From this state, when the stopper 3 is pushed into the opening 21 against the urging force of the coil spring S and pushed into the opening 21, the trace pin 29 advances through the introduction groove a and enters the forward groove b, and further the locking guide. Go through groove c. When the trace pin 29 comes into contact with the inner wall of the guide groove c and the stopper 3 can no longer be pushed in, the hand is released from the stopper 3 to release the pushing force. Then, the stopper 3 is slightly rotated in the projecting direction by the urging force (restoring force) of the coil spring S, and the trace pin 29 moves backward in the guide groove c along with this, but the stopper 3 enters the forward groove b due to the step. In order to enter the locking portion d that is lowered by one step, the locking portion d falls and is locked. As a result, the stopper 3 is held in the opening 21 against the urging force of the coil spring S as shown in FIG.

When switching the stopper 3 to the projecting state, push the stopper 3 from the outside by hand and then release it. In this process, since the trace pin 29 cannot reversely move the locking portion d at the time of pushing, it proceeds to the adjacent release guide groove e. When the release force is released by releasing the hand, the stopper 3 is rotated in the projecting direction by the urging force of the coil spring S, and the trace pin 29 is slightly reversed in the guide groove e and introduced through the return groove f. It progresses to the groove | channel a and remove | deviates from the introduction groove | channel a. As a result, the stopper 3 is switched to the protruding state as shown in FIG.

It should be noted that the pinching prevention tool according to the embodiment of the present invention and the modification thereof described above may have a configuration specified by the description of the scope of claims, and details are changed with reference to each embodiment. Can be deployed. For example, instead of a coil spring as a biasing means, a plate spring or a resin spring is used, a rotating damper is used as a braking means, and a stopper is moved back and forth to switch between a projecting state and a retracted state. It is.
