Description

[Technical field]

[0001] This case relates to a door stopper that is manually opened and closed. [Background technology]

[0002] Conventionally, elastic bodies have been used to prevent interference between components when the door is opened and closed. For example, Patent Document 1 discloses a stopper structure for preventing interference between a sliding door of a vehicle and a vehicle body when the sliding door is closed, in which a part of the stopper body is made of rubber.

[0003] [Patent Document 1] JP 2003-172069 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, depending on the usage conditions, manually opened and closed doors may close from an open state against the user's will. For example, a manually opened and closed folding door or sliding door installed at the entrance of a vehicle may close by itself due to its own weight if it is opened while the vehicle is stopped on a slope. For this reason, it is desirable for the door stopper to have a function of preventing interference between parts, as well as a function of holding the door in an open state.

[0005] The present invention has been devised in consideration of the above-mentioned problems, and one of its objects is to provide a door stopper that can prevent interference between components and hold the door in an open position. [Means for solving the problem]

[0006] The present invention has been made to solve at least part of the above problems, and can be realized in the following aspects or application examples. The door stopper according to this application example is a door stopper that is opened and closed manually, and is characterized by comprising: a male member that is fixed to one of two members whose relative position changes as the door is opened and closed, and has a pillar-shaped protruding support portion and a claw portion provided in a flange-like shape on the outer periphery of the support portion; and a female member that is fixed to the other of the two members and is formed of an elastic body, and has an end surface with which the claw portion can abut when the door is in an open state with the two members close to each other, and a groove portion into which the claw portion pressed against the end surface can fit.

[0007] According to this application example, when the door is in an open state, the claw portion of the male member fixed to one of the two members whose relative position changes as the door is opened and closed abuts against the end face of the female member fixed to the other of the two members, thereby preventing interference between the two members. Also, when the door is in an open state, the claw portion of the male member is pressed against the end face of the female member made of an elastic body, and fits into the groove of the female member, thereby fixing the relative positions of the two members. This allows the door to be held in an open state. Effect of the Invention

[0008] According to the present invention, it is possible to provide a door stopper that can prevent interference between members and can hold the door in an open state. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The following describes the embodiments (application examples) of the present invention with reference to the drawings. The following embodiments are merely examples, and are not intended to exclude various modifications or applications of techniques not clearly stated in the embodiments. The configurations of the following embodiments can be modified in various ways without departing from the spirit of the embodiments. They can also be selected or combined as necessary.

[0011] [1. Configuration] As shown in FIG. 1, a door stopper 1 according to this embodiment (hereinafter, simply referred to as "stopper 1") is applied to a folding door 3 (door) of a vehicle 2. The vehicle 2 is, for example, a small bus. The folding door 3 is a manually opened and closed door that is manually opened and closed when a passenger gets on and off, and is provided on the left side of the vehicle 2. The folding door 3 is switched between a closed state in which a door opening 7 formed on the left side of the vehicle 2 as an entrance and exit opening is closed, and an open state in which the door opening 7 is opened, by a manual operation in which the passenger pushes or pulls the folding door 3. In the drawings, "FR" indicates the front of the vehicle 2, and "UP" indicates the upper side of the vehicle 2. Hereinafter, the front-rear direction of the vehicle 2 is also referred to as the "vehicle length direction", the left-right direction of the vehicle 2 is also referred to as the "vehicle width direction", and the up-down direction of the vehicle 2 is also referred to as the "vehicle height direction".

[0012] As shown in FIG. 2, the folding door 3 has a pair of panels (two members) 4, 5 arranged in the vehicle length direction D1. These panels 4, 5 are rotatably connected via a hinge 6, and the relative position changes as the folding door 3 opens and closes. Each panel 4, 5 has a long and narrow rectangular shape and has an outer panel 41, 51 and an inner panel (not shown). In each panel 4, 5, a hollow space is formed between the outer panel 41, 51 and the inner panel. Hereinafter, of the pair of panels 4, 5, the panel 4 arranged on the front side is also referred to as the "front panel 4", and the other panel 5 arranged on the rear side is also referred to as the "rear panel 5".

[0013] In this embodiment, the front edge 4a of the front panel 4 is connected to the front edge 7a of the door opening 7 so as to be rotatable about a rotation axis (not shown), and the rear edge 4b ​​of the front panel 4 is connected to the front edge 5a of the rear panel 5 by multiple hinges 6. On the other hand, the rear edge 5b of the rear panel 5 is provided so as to be separable from the rear edge 7b of the door opening 7, and the upper and lower ends of the rear edge 5b of the rear panel 5 are supported by the upper edge 7c of the door opening 7 so as to be slidable.

[0014] As shown by solid lines in FIG. 2, when the folding door 3 is in a closed state, each panel 4, 5 extends along the vehicle length direction D1 and the vehicle height direction D3, and the rear edge portion 5b of the rear panel 5 is disposed at the rear edge portion 7b of the door opening 7 without a gap. On the other hand, as shown by two-dot chain lines in FIG. 2, when the folding door 3 is in an open state, the front edge portion 4a of the front panel 4 rotates inward in the vehicle width direction with respect to the front edge portion 7a of the door opening 7 around the above-mentioned rotation axis. As a result, the rear edge portion 4b of the front panel 4 and the front edge portion 5a of the rear panel 5, which are connected by the hinge 6, are disposed inward in the vehicle width direction from the door opening 7, and each panel 4, 5 forms a V shape that opens outward in the vehicle width direction when viewed from the vehicle height direction D3. In such an open state of the folding door 3, the rear edge portion 5b of the rear panel 5 is separated from the rear edge portion 7b of the door opening 7, and the pair of panels 4, 5 are close to each other so as to face each other.

[0015] For example, when the vehicle 2 stops on an uphill slope, the rear panel 5 is positioned diagonally below the front panel 4. In this case, even if the rear panel 5 is moved toward the front panel 4 to open the folding door 3, the rear panel 5 may move in the direction of closing due to its own weight. Therefore, when opening the folding door 3 while the vehicle 2 is stopped on an uphill slope, it is desirable to hold the folding door 3 in the open state by the stopper 1. Note that, in contrast to the mounting structure of the folding door 3 of this embodiment, in a folding door in which the rear edge 5b of the rear panel 5 is rotatably connected to the rear edge 7b of the door opening 7 and the front edge 4a of the front panel 4 is provided so as to be separable from the front edge 7a of the door opening 7, a similar event may occur while the vehicle is stopped on a downhill slope.

[0016] In this embodiment, the stoppers 1 are disposed at two locations, above and below the folding door 3. However, the number and location of the stoppers 1 are not limited to this, and for example, the stoppers 1 may be disposed at only one location, which is the center of the folding door 3 in the vehicle height direction D3, or the stoppers 1 may be disposed at three or more locations spaced apart in the vehicle height direction D3 of the folding door 3.

[0017] As shown in Fig. 3, the stopper 1 includes a male member 10 fixed to one of the pair of panels 4, 5, and a female member 20 fixed to the other of the pair of panels 4, 5. In this embodiment, a stopper 1 in which the male member 10 is fixed to the front panel 4 and the female member 20 is fixed to the rear panel 5 is exemplified. However, opposite to this embodiment, a stopper 1 in which the male member 10 is fixed to the rear panel 5 and the female member 20 is fixed to the front panel 4 may also be applied. In either case, one male member 10 and one female member 20 are paired to form one stopper 1.

[0018] The male member 10 has a support portion 11 protruding in a columnar shape from the outer panel 41 of the front panel 4, and a claw portion 12 provided in a flange shape on the outer periphery of the support portion 11. In this embodiment, a male member 10 in which the support portion 11 is formed by a bolt 8 and a collar 13 and the claw portion 12 is formed by a washer is exemplified. The bolt 8 is fixed by inserting a screw portion 8a into a through hole 42 formed in the outer panel 41 of the front panel 4. The head portion 8b of the bolt 8 forms the tip portion of the support portion 11 and is disposed outside the outer panel 41 (outside the front panel 4 of the folding door 3 in the closed state in the vehicle width direction). The support portion 11 of this embodiment is protruding in a direction substantially perpendicular to the outer panel 41 by the bolt 8.

[0019] The collar 13 is a spacer disposed between the outer panel 41 and the claw portion 12. In this manner, by disposing the collar 13 in addition to the washer functioning as the claw portion 12 between the outer panel 41 and the head 8b of the bolt 8, the position of the washer is stabilized. Note that the washer forming the claw portion 12 is not limited to being made of iron, and may be made of an elastic body (e.g., rubber).

[0020] The female member 20 is formed of an elastic body (e.g., rubber) and is disposed at a position facing the male member 10 when the folding door 3 is in an open state. The female member 20 is, for example, a rubber bushing with a cylindrical external shape. When the folding door 3 is in an open state, the female member 20 has an end surface 23 against which the claw portion 12 of the male member 10 can come into contact, and a groove portion 22 into which the claw portion 12 of the male member 10 pressed against the end surface 23 can fit. The female member 20 of this embodiment further has a recess 21 capable of accommodating the tip end of the support portion 11 of the male member 10. The recess 21 is a portion recessed from the end surface 23, and is, for example, substantially cylindrical and larger than the tip end of the support portion 11 of the male member 10.

[0021] The female member 20 of this embodiment is fixed to the outer panel 51 of the rear panel 5 by a bolt 9, and is disposed outside the outer panel 51 (outside in the vehicle width direction of the rear panel 5 of the folding door 3 in the closed state). More specifically, the bolt 9 is inserted through both a through hole 25 formed in the female member 20 and a through hole 52 formed in the outer panel 51, and then fixed. Note that in the female member 20, the through hole 25 is connected to the recess 21.

[0022] The end face 23 is formed, for example, in a flat shape, and faces the male member 10 when the folding door 3 is in an open state. On the other hand, the groove portion 22 is a portion recessed radially outward from the recessed portion 21 (vertical direction in FIG. 3 ), and is formed in a ring shape that is approximately the same as or slightly larger than the claw portion 12 of the male member 10. The groove portion 22 is formed inward (toward the outer panel 51) from the end face 23 by a certain thickness dimension T.

[0023] In the female member 20, a flesh portion 24 between the end face 23 and the groove portion 22 is elastically deformed when the claw portion 12 of the male member 10 is pressed against the end face 23. As a result, the claw portion 12 of the male member 10 climbs over the flesh portion 24 of the female member 20 and fits into the groove portion 22. When the claw portion 12 of the male member 10 is fitted into the groove portion 22 of the female member 20, the male member 10 and the female member 20 are locked together, and the relative positions of the pair of panels 4, 5 are fixed.

[0024] As described above, the flesh portion 24 of the female member 20 is a portion that is particularly required to have strength since it is elastically deformed every time the male member 10 and the female member 20 are locked together. In this regard, the strength (durability) of the female member 20 improves as the thickness dimension T from the end face 23 of the female member 20 to the groove portion 22 increases. However, on the other hand, the claw portion 12 of the male member 10 becomes more difficult to fit into the groove portion 22 of the female member 20 as the thickness dimension T increases. For this reason, it is preferable that the thickness dimension T be set in consideration of the balance between the strength required of the female member 20 and the fit between the claw portion 12 of the male member 10 and the groove portion 22 of the female member 20.

[0025] [2. Effect] As shown in FIG. 4, when the folding door 3 is in an open state, the pair of panels 4, 5 are close to each other so as to face each other, and the male member 10 and the female member 20 of the stopper 1 are arranged to face each other. When the folding door 3 is simply opened and there is no need to hold the folding door 3 in an open state, the interval between the panels 4, 5 is secured so that the claw portion 12 of the male member 10 simply abuts against the end surface 23 of the female member 20. That is, in this case, although the tip portion of the support portion 11 of the male member 10 is accommodated in the recess 21 of the female member 20, the panels 4, 5 are arranged so that the claw portion 12 of the male member 10 only abuts against the end surface 23 of the female member 20 and does not fit into the groove portion 22. Therefore, in this case, the male member 10 and the female member 20 are interposed between the panels 4, 5, and the stopper 1 simply functions to prevent the panels 4, 5 from interfering with each other.

[0026] On the other hand, when it is desired to keep the folding door 3 open, for example, while the vehicle 2 is stopped on an uphill road, the claw portion 12 of the male member 10 is pressed against the end face 23 of the female member 20, narrowing the gap between the panels 4, 5 so that the claw portion 12 of the male member 10 passes over the end face 23 and fits into the groove portion 22, as shown in Fig. 5. That is, in this case, the rear panel 5 is pressed toward the front panel 4 so that the claw portion 12 of the male member 10 pressed against the end face 23 of the female member 20 elastically deforms the flesh portion 24 of the female member 20 and enters the groove portion 22. Therefore, in this case, the male member 10 and the female member 20 are locked to each other, and the stopper 1 not only prevents interference between the panels 4, 5, but also keeps the folding door 3 open.

[0027] When a force is applied in a direction separating the male member 10 and the female member 20 locked as described above in association with the operation of closing the folding door 3, the claw portion 12 of the male member 10 elastically deforms the flesh portion 24 of the female member 20 again, and the claw portion 12 is released from the groove portion 22. This releases the lock between the male member 10 and the female member 20 and the folding door 3 is no longer held in the open state, allowing the folding door 3 to be closed.

[0028] [3. Effects] According to the stopper 1 described above, when the folding door 3 is in an open state, the claw portion 12 of the male member 10 fixed to the front panel 4 can come into contact with the end surface 23 of the female member 20 fixed to the rear panel 5. Therefore, when the folding door 3 is in an open state in which the panels 4, 5 are close to each other, the claw portion 12 of the male member 10 comes into contact with the end surface 23 of the female member 20, thereby preventing interference between the panels 4, 5.

[0029] Furthermore, according to the stopper 1, when the folding door 3 is in the open state, the claw portion 12 of the male member 10 pressed against the end surface 23 of the female member 20, which is an elastic body, can fit into the groove portion 22 of the female member 20. Therefore, when the folding door 3 is in the open state, the claw portion 12 of the male member 10 is pressed against the end surface 23 and fits into the groove portion 22 of the female member 20, thereby fixing the relative positions of the panels 4, 5. This makes it possible to hold the folding door 3 in the open state. Therefore, according to the stopper 1, it is possible to prevent interference between the panels 4, 5 and to hold the folding door 3 in the open state.

[0030] If the claw portion 12 of the male member 10 is formed of an elastic body, it is possible to reduce the impact that the female member 20 receives when the claw portion 12 of the male member 10 is pressed against the end surface 23 of the female member 20. This makes it possible to suppress damage to the periphery of the flesh portion 24 of the female member 20. Furthermore, when unlocking the male member 10 and the female member 20, the claw portion 12 of the male member 10 is easily disengaged from the groove portion 22 of the female member 20 due to elastic deformation, so that the open state of the folding door 3 can be released with less force.

[0031] If the stopper 1 is provided at two locations, above and below the folding door 3, interference between the panels 4, 5 can be prevented at two locations, above and below, compared to when it is provided at one location, and the relative positions of the panels 4, 5 can be more firmly locked. Therefore, interference between the panels 4, 5 can be more reliably prevented, and the folding door 3 can be more reliably held in the open state.

[0032] [4.Other] The configurations of the male member 10 and the female member 20 shown in the above embodiment are merely examples. In the male member 10, the support portion 11 may be formed of parts other than the bolt 8 and collar 13, and the claw portion 12 may be formed of parts other than the washer. However, if the support portion 11 and the claw portion 12 of the male member 10 are formed of general-purpose bolts, collars, and washers as in the above embodiment, the parts cost can be reduced. In addition, the external shape of the female member 20 is not limited to the cylindrical shape as described above, and may be, for example, a rectangular column shape. The male member 10 and the female member 20 may be fixed to the panels 4 and 5 by means other than the bolts 8 and 9, respectively.

[0033] The stopper 1 is not limited to the folding door 3 of the vehicle 2, and may be applied to, for example, a sliding door of a vehicle. In a stopper applied to a sliding door, for example, a male member 10 may be fixed to one of the sliding door and the vehicle body (two members) whose relative position changes as the sliding door is opened and closed, and a female member 20 may be fixed to the other of the sliding door and the vehicle body. In this case, interference between the sliding door and the vehicle body can be prevented, and a sliding door that is manually opened and closed can be held in an open state. Furthermore, the stopper 1 is not limited to the folding door 3 or sliding door of the vehicle 2, and may be applied to various doors that are required to be held in an open state, and may be applied to things other than vehicles.
