Description

Technical Field

[0001] The present invention relates to a stopper for a sliding door that defines the fully open position of the door panel of the sliding door and allows the user to open it further than the fully open position by operating it, and a sliding door provided with the same.

Background Art

[0002] Conventionally, when opening the door panel of a sliding door, a stopper for a sliding door has been developed that prevents the door panel from opening beyond a predetermined position while allowing the door panel to be opened further than the predetermined position by releasing the lock (for example, Patent Document 1).

[0003] The stopper for a sliding door according to Patent Document 1 includes an integrally formed lever that abuts against a block body attached to the floor so that the sliding door does not open beyond a predetermined position. This lever is configured to rotate about a rotation axis extending in the plate thickness direction of the sliding door, and by rotating the lever, the abutting state and the released state of the lever against the block body can be configured.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, as described above, the stopper for a sliding door of Patent Document 1 releases the abutting state against the block body by integrally rotating the lever in a state where the tip of the lever abuts against the block body attached to the floor about the rotation axis.

[0006] When the lever is rotated, the trajectory of the tip of the lever traces an arc diagonally upwards in the diagram, that is, it protrudes further towards the block from the point of contact. Therefore, in order to release the contact with the block, the tip of the lever must be slightly away from the block. This is because if the tip of the lever remains in contact with the block, the lever cannot be rotated.

[0007] In recent years, automatic full-opening devices have become common on sliding doors, which automatically move the door panel to the fully open position once the user has opened it to a certain extent. However, when such an automatic full-opening device is installed, the door panel is always biased in the "opening direction" even in the fully open position. Therefore, when the sliding door stopper described in Patent Document 1 is installed, there is a problem in that the user must operate the sliding door stopper while resisting the biasing force in the opening direction caused by the automatic full-opening device by slightly moving the door panel in the closing direction to separate the tip of the lever from the block body.

[0008] This invention was developed in view of the problems of the prior art. Therefore, the main objective of this invention is to provide a sliding door stopper that can release the contact state with the block body even when the door panel is in the fully open position, and a sliding door equipped therewith. [Means for solving the problem]

[0009] According to one aspect of the present invention, A base that is attached to the lower end of the door panel, A sliding door stopper comprising a contact member housed within the base and in contact with a block body placed on the floor, The aforementioned contact member is A switch member that slides within the base toward the block body, It has a stopper member, one end of which is rotatably attached to the switch member and the other end of which is able to abut against the block body. A guide pin is provided protruding from the other end. The guide pin slides through a guide hole formed in the base, which extends downward in an arc shape toward the block body. A stopper for sliding doors is provided.

[0010] Preferably, A separation biasing member that biases the switch member in a direction away from the block body, The switch member maintains a contact state in which it has moved toward the block body against the biasing force of the separation biasing member, In the aforementioned contact state, if the end of the switch member opposite to the end to which the stopper member is attached is further pushed toward the block body, the device further includes an on / off mechanism that moves the stopper member to a position further away from the block body by the biasing force of the separation biasing member.

[0011] Preferably, The system further includes a biasing member that biases the contact member toward the block body.

[0012] Preferably, The stopper member is rotatably attached to the switch member via a pivot pin.

[0013] Preferably, The pivot pin slides through a pivot pin guide slot formed in the base, which extends toward the block body.

[0014] Preferably, The other end of the stopper member, on the side opposite to the contact portion that abuts the block body, is tapered downward toward the block body when the stopper member is in a state where it can abut the block body.

[0015] According to another aspect of the present invention, A sliding door is provided that includes the aforementioned sliding door stopper, a block body, and a door panel. [Effects of the Invention]

[0016] According to the sliding door stopper of the present invention, the contact member that contacts the block body arranged on the floor includes a switch member that slides inside the base toward the block body, and a stopper member whose one end is rotatably attached to the switch member and whose other end can contact the block body. The stopper member has a guide pin protruding therethrough that slides in a guide elongated hole formed in the base and arcs downward toward the block body.

[0017] Thus, by sliding the switch member with respect to the base, it is possible to select a state where the other end of the stopper member can contact the block body (a state where the guide pin is positioned at the arc-shaped lower end in the guide elongated hole) and a state where the other end of the stopper member does not contact the block body (a state where the guide pin is positioned at the arc-shaped upper end in the guide elongated hole).

[0018] In particular, since the other end of the stopper member (the portion that contacts the block body) moves along the guide elongated hole formed so as to arc downward toward the block body, when changing the stopper member from a contact state to a non-contact state with respect to the block body, as shown in FIG. 9, the other end of the stopper member does not protrude toward the block body.

[0019] Thus, it is possible to provide a sliding door stopper that can release the contact state with the block body even when the door panel is in the fully open position.

[Modes for carrying out the invention]

[0021] (Configuration of a sliding door 10 equipped with a sliding door stopper 100) The following describes a sliding door 10 equipped with a sliding door stopper 100 to which the present invention is applied, using the drawings. As shown in Figure 1, the sliding door 10 according to this embodiment consists of at least a door panel 12, a rail 14, a runner 16, a sliding door stopper 100, and a block body 18.

[0022] Furthermore, while the sliding door 10 according to this embodiment is housed in a door pocket 22 formed between a pair of wall materials 20, it is not limited to this configuration.

[0023] The rail 14 is attached to the top surface of the opening where the sliding door 10 is installed, and has a runner running surface 24 on which the runner 16, which is attached to the top surface of the door panel 12, runs. The material that makes up the rail 14 can be any material such as metal, resin, or wood, as long as it can ensure the necessary strength.

[0024] The sliding door stopper 100 works in cooperation with the block body 18 to prevent the door panel 12 from being further enclosed in the door pocket 22 when the door panel 12 is in a predetermined fully open position (in this embodiment, the position in which most of the door panel 12 is housed in the door pocket 22, and only the handle 26 located on the widthwise edge of the door panel 12 is exposed from the door pocket 22). When necessary, it also releases the lock to open the door panel 12 further than the fully open position (for example, to house the entire door panel 12 in the door pocket 22).

[0025] As shown in Figure 2, the sliding door stopper 100 according to this embodiment generally comprises a base 102, a contact member 104, a biasing member 106, a biasing member stopper 107, a pivoting pin 108, a guide pin 110, and a cover 112.

[0026] The base 102 is a roughly rectangular parallelepiped member attached to the lower end of the door panel 12 (in this embodiment, the lower end of the door panel 12 at the widthwise end furthest from the block body 18), and as shown in Figure 3, it has an internal space 114 for accommodating the contact member 104, the biasing member 106, etc. The material constituting the base 102 can be any material such as metal, resin, or wood, as long as it can ensure the necessary strength.

[0027] Furthermore, a block body introduction hole 116 is formed on the end face of the base 102 facing the block body 18, connecting the internal space 114 to the outside and allowing the block body 18 to be introduced. In addition, an upper opening 117 is formed on the upper surface of the base 102, connecting the internal space 114 to the outside.

[0028] Furthermore, guide slots 118 and rotating pin guide slots 120 are formed on both sides of the base 102.

[0029] As will be described later, the guide slot 118 is an elongated slot through which the guide pin 110 slides, and it has an arc shape that extends downward toward the block body.

[0030] As will be described later, the rotating pin guide slot 120 is a slot through which the rotating pin 108 slides, and it has a shape that extends approximately horizontally toward the block body 18.

[0031] The contact member 104 is housed in the internal space 114 of the base 102 and is a member that contacts the block body 18 placed on the floor. As shown in Figure 4, it is composed of a switch member 122 and a stopper member 124.

[0032] The switch member 122 is a member that slides within the internal space 114 of the base 102 toward the block body 18. In this embodiment, the tip of the switch member 122 and the stopper member 124 are pivotally supported by a pivot pin 108, and the pivot pin 108 is inserted into a pivot pin guide slot 120 formed on the side surface of the base 102 and slides. As described above, since the pivot pin guide slot 120 has a shape that extends substantially horizontally toward the block body 18, the pivot pin 108 and the switch member 122 also slide within the base 102 in a substantially horizontal direction toward the block body 18.

[0033] Furthermore, an operating part 128 is formed at the rear end of the switch member 122 for the user to operate the switch member 122 (in this embodiment, by pulling the switch member 122 in a direction away from the block body 18). In addition, a biasing member housing groove 130 is formed in the switch member 122 for housing the biasing member 106.

[0034] The stopper member 124 has one end that is rotatably attached to the switch member 122, and the other end is a contact portion 126 that abuts against the block body 18.

[0035] Furthermore, a guide pin 110 is provided at the other end of the stopper member 124 in a direction perpendicular to the direction of movement of the stopper member 124. This guide pin 110 is inserted through a guide slot 118 formed on the side surface of the base 102 and slides within the guide slot 118.

[0036] Furthermore, the other end of the stopper member 124, the surface opposite to the contact portion 126 that abuts against the block body 18, is a tapered surface 134 that points downward toward the block body 18 when the stopper member 124 is in a state where it can abut against the block body 18.

[0037] Returning to Figure 2, the biasing member 106 is a member for biasing the contact member 104 (more specifically, the switch member 122) toward the block body 18, and is housed in the biasing member housing groove 130 of the switch member 122. One end of the biasing member 106 is in contact with the switch member 122 within the biasing member housing groove 130. In this embodiment, a helical spring is used as the biasing member 106, but it is not limited to this as long as it biases the contact member 104 toward the block body 18. Furthermore, the biasing member 106 is not an essential component, and the sliding door stopper 100 may be constructed without the biasing member 106. However, if the biasing member 106 is omitted, the user will need to perform both the action of pulling the operating part 128 of the switch member 122 and the action of returning the operating part 128.

[0038] As shown in Figures 5 and 6, the biasing member stopper 107 is a member that contacts the other end of the biasing member 106, thereby restricting one end of the biasing member 106 from always biasing the switch member 122 toward the block body 18, and has a biasing member restricting portion 132 and a base mounting portion 136.

[0039] In this embodiment, the base mounting portion 136 of the biasing member stopper 107 is fixed to the base 102 so as to straddle the upper opening 117 of the base 102, and in this state, the biasing member restricting portion 132 is fitted into the biasing member housing groove 130 of the switch member 122 (see Figure 6).

[0040] As a result, when the user pulls the operating part 128 of the switch member 122 and slides the switch member 122 away from the block body 18, the biasing member 106 is compressed by being sandwiched between the biasing member restricting part 132 and the biasing member housing groove 130 of the switch member 122 (Figure 6(a)). In this state, when the user releases their hand from the operating part 128, the biasing member 106 expands and slides the switch member 122 closer to the block body 18 (Figure 6(b)).

[0041] (How to use the sliding door stopper 100) Next, the method of using the sliding door stopper 100 according to this embodiment will be briefly described. First, when the user releases their hand from the operating part 128 of the switch member 122, as shown in Figure 7, the biasing member 106 biases the switch member 122 toward the block body 18, so that the pivot pin 108 attached to the switch member 122 is located at the end of the pivot pin guide slot 120 that is closer to the block body 18. As a result, the stopper member 124, which is pushed by the switch member 122, is also guided by the guide pin 110 that slides through the guide slot 118, so that the other end (contact portion 126) of the stopper member 124 is located at the lower end that is closer to the block body 18.

[0042] As a result, the contact portion 126 of the stopper member 124 is also located at the lowest position, and when the door panel 12 is moved, it comes into contact with the block body 18 that enters the internal space 114 through the block body introduction hole 116 of the base 102.

[0043] From this state, when the user pulls the operating portion 128 of the switch member 122 away from the block body 18, as shown in Figure 8, the switch member 122 slides away from the block body 18 against the biasing force of the biasing member 106, and the stopper member 124, which is pulled by the switch member 122, is also guided by the guide pin 110 which slides through the guide slot 118, so that the other end (contact portion 126) of the stopper member 124 moves to the upper end which is spaced away from the block body 18.

[0044] In this state, the stopper member 124 does not come into contact with the block body 18, so the door panel 12 can be moved further into the door pocket 22 (moved to the right in Figure 8) from the fully open position (the position shown in Figure 7).

[0045] As described above, the other end of the stopper member 124, the surface opposite to the contact portion 126 that abuts against the block body 18, is a tapered surface 134 that points downward toward the block body 18 when the stopper member 124 is in a state where it can abut against the block body 18. Therefore, when the door panel 12 is moved from the fully open state to the door pocket 22 (that is, when the block body 18 is on the opposite side of the contact portion 126 of the stopper member 124 [to the left of the stopper member 124 in Figure 8]), and the user releases their hand from the operating unit 128, the contact portion 126 of the stopper member 124 is again in its lowest position, and the door panel 12 is moved in the closing direction, the block body 18 will hit the tapered surface 134 of the stopper member 124, and as the door panel 12 is moved further in the closing direction, the stopper member 124 will move upward due to the pressing force from the block body 18. Thus, when returning the door panel 12 from the state where it is stored in the door pocket 22 to the fully open state, the user does not need to operate the control unit 128.

[0046] (Function of sliding door stopper 100) According to the sliding door stopper 100 of this embodiment, the contact member 104 that contacts the block body 18 placed on the floor has a switch member 122 that slides within the base 102 toward the block body 18, and a stopper member 124 whose one end is rotatably attached to the switch member 122 and whose other end is capable of contacting the block body 18. The stopper member 124 is provided with a guide pin 110 that slides through a guide slot 118 formed in the base 102, which extends downward in an arc toward the block body 18.

[0047] As a result, by sliding the switch member 122 against the base 102, it is possible to select between two states: as shown in Figure 7, where the other end of the stopper member 124 can contact the block body 18 (with the guide pin 110 positioned at the lower arc-shaped end of the guide slot 118); and as shown in Figure 8, where the other end of the stopper member 124 does not contact the block body 18 (with the guide pin 110 positioned at the upper arc-shaped end of the guide slot 118).

[0048] In particular, since the other end of the stopper member 124 (the part that abuts against the block body 18) moves along the guide slot 118 which is formed to curve downward toward the block body 18, when the stopper member 124 is moved from a contact state to a non-contact state toward the block body 18, the other end of the stopper member 124 (the contact portion 126) does not protrude toward the block body 18, as shown in Figure 9 (see trajectory Z).

[0049] This makes it possible to release the contact between the door panel 12 and the other end of the stopper member 124 and the block body 18, even when the door panel 12 is in the fully open position and the other end of the stopper member 124 is in contact with the block body 18.

[0050] (Variation 1) In the embodiment described above, the contact state of the contact member 104 was released by the user pulling the operating part 128 of the switch member 122 away from the block body 18, and the contact member 104 returned to the contact state by the biasing force of the biasing member 106 when the operating part 128 was released. Alternatively, the contact state of the contact member 104 may be released by the user pushing the operating part 128 of the switch member 122 toward the block body 18.

[0051] Specifically, the sliding door stopper 100 is configured as shown in Figure 10. Note that the sliding door stopper 100 according to Modification 1 will be described primarily in terms of its differences from the sliding door stopper 100 according to the above embodiment, while the common parts will be explained by referring to the description of the sliding door stopper 100 according to the embodiment.

[0052] The sliding door stopper 100 according to the modified example 1 generally comprises a base 102, a contact member 104, a separation direction biasing member 140, a rotation pin 108, a guide pin 110, a cover 112, and an on / off mechanism 142.

[0053] The contact member 104 is housed in the internal space 114 of the base 102 and is a member that contacts the block body 18 placed on the floor. As shown in Figure 11, it is composed of a switch member 122 and a stopper member 124.

[0054] The switch member 122 is a member that slides within the internal space 114 of the base 102 toward the block body 18. In this modified example 1, a lock pin guide groove 144, which constitutes the on / off mechanism 142, is formed on the upper surface of the switch member 122.

[0055] The lock pin guide groove 144 is a groove into which the tip of the lock pin 146, which will be described later, is fitted. It has a contact position 148 where the tip of the lock pin 146 is located when the switch member 122 is in contact with the block body 18, a release position 150 which is closer to the block body 18 than the contact position 148 and where the tip of the lock pin 146 is located when the switch member 122 moves away from the block body 18 and the contact is released, and a pair of connecting grooves 154 which connect the contact position 148 and the release position 150 and have an intermediate position 152 in which the switch member 122 moves further toward the block body 18 than the contact position 148.

[0056] The separation-direction biasing member 140 is a member for biasing the contact member 104 (more specifically, the switch member 122) in a direction away from the block body 18, and is housed in the internal space 114 of the base 102. One end of the separation-direction biasing member 140 abuts against the end of the switch member 122 facing the block body 18. Furthermore, the other end of the separation-direction biasing member 140 abuts against the inside of the base 102. In this embodiment, a helical spring is used as the separation-direction biasing member 140, but it is not limited to this as long as it biases the contact member 104 in a direction away from the block body 18.

[0057] The on / off mechanism 142 maintains a contact state in which the switch member 122 has moved toward the block body 18 against the biasing force of the separation biasing member 140. In this contact state, if the end of the switch member 122 opposite to the end to which the stopper member 124 is attached is further pushed toward the block body 18, the mechanism has the role of moving the stopper member 124 to a position further away from the block body 18 by the biasing force of the separation biasing member 140.

[0058] This on / off mechanism 142 consists of a lock pin 146, the aforementioned lock pin guide groove 144, and a separation direction biasing member 140.

[0059] The lock pin 146 is a component formed by bending a thin rod-shaped member into a roughly "U" shape, with one end fitted into a lock pin guide groove 144 formed on the surface of the switch member 122. The other end of the lock pin 146 is fixed to the base 102.

[0060] (How to use the sliding door stopper 100) Next, the method of using the sliding door stopper 100 according to Modification 1 will be briefly explained. First, when the user pushes the operating part 128 of the switch member 122 toward the block body 18, as shown in Figures 12 and 13, the on / off mechanism 142 maintains the contact state in which the switch member 122 has moved toward the block body 18 against the biasing force of the separation direction biasing member 140. Specifically, the tip of the lock pin 146 is in contact position 148 of the lock pin guide groove 144 and is stopped.

[0061] As a result, the stopper member 124, which is pressed by the switch member 122, is also guided by the guide pin 110 which slides through the guide slot 118, and the other end (contact portion 126) of the stopper member 124 is located at the lower end close to the block body 18. Consequently, the contact portion 126 of the stopper member 124 is also located at the lowest position and will come into contact with the block body 18 that enters the internal space 114 through the block body introduction hole 116 of the base 102 when the door panel 12 is moved.

[0062] From this state, when the user pushes the operating part 128 of the switch member 122 toward the block body 18, as shown in Figure 14, the switch member 122 slides slightly closer to the block body 18 against the biasing force of the separation biasing member 140, and the tip of the lock pin 146 moves to an intermediate position 152 in the lock pin guide groove 144.

[0063] Subsequently, when the user releases their hand from the operating part 128 of the switch member 122, the biasing force of the separation direction biasing member 140 causes the switch member 122 to move away from the block body 18, and as shown in Figure 15, the tip of the lock pin 146 moves to the released position 150 of the lock pin guide groove 144.

[0064] In this state, the stopper member 124, which is pulled by the switch member 122, is also guided by the guide pin 110 which slides through the guide slot 118, and the other end (contact portion 126) of the stopper member 124 moves to the upper end which is spaced away from the block body 18. In this state, the stopper member 124 does not come into contact with the block body 18, so the door panel 12 can be moved from the fully open state to a state where it is housed in the door pocket 22.

[0065] Again, when the user pushes the operating part 128 of the switch member 122 toward the block body 18, the switch member 122 slides toward the block body 18 against the biasing force of the separation biasing member 140, and as shown in Figure 16, the tip of the lock pin 146 moves to the intermediate position 152 of the lock pin guide groove 144. Then, when the user releases their hand from the operating part 128 of the switch member 122 in this state, the biasing force of the separation biasing member 140 moves the switch member 122 toward a slight distance from the block body 18, returning it to the state shown in Figure 13 (contact state).

[0066] (Modification 2) In the embodiment described above, the stopper member 124 was rotatably attached to the switch member 122 via a pivot pin 108. However, the stopper member 124 is not limited to this, as long as it is rotatable relative to the switch member 122. For example, the stopper member 124 and the switch member 122 may be connected by a highly flexible film-like member.

[0067] (Variation 3) Furthermore, in the above-described embodiment, the pivot pin 108 was configured to slide through a pivot pin guide slot 120 formed in the base 102. However, the pivot pin guide slot 120 may be omitted if the switch member 122 can be slid in a substantially horizontal direction. For example, it is conceivable to form a projection on the inner wall of the base 102 facing the internal space 114 that extends substantially horizontally and on which the switch member slides.

[0068] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
