[Technical Field]

[0001] The present invention relates to a door-side member of a door stop device. [Background technology]

[0002] BACKGROUND ART Conventionally, a door-side member of a door stop device provided at the lower end of a hinged door is known (see, for example, Patent Document 1).

[0003] The door-side member of the doorstop device has a rod-shaped member that is capable of abutting against the floor-side member of the doorstop device. The rod-shaped member is installed on the door surface, has a cylindrical shape that extends vertically, and is spaced apart from the floor surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-275391 Summary of the Invention [Problem to be solved by the invention]

[0005] Here, if the hinged door tilts due to deterioration over time or the like and the rod-shaped member comes into contact with the floor surface, there is a risk that the floor surface will be damaged.

[0006] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a door-side member of a door stop device that can suppress damage to the floor surface. [Means for solving the problem]

[0007] The door-side member of the doorstop device according to the present invention is provided at the lower end of a hinged door and includes an abutment portion that abuts against the floor-side member of the doorstop device. The abutment portion includes a cylindrical body, a tip part that is provided inside the cylindrical body so as to be movable up and down, and a biasing member that biases the tip part downward. The tip part is disposed so as to protrude below the lower end of the cylindrical body and is configured to be able to retract upward against the biasing force of the biasing member.

[0008] With this configuration, when the hinged door tilts due to aging or the like and the tip part comes into contact with the floor surface, the tip part is retracted upward, thereby reducing the contact pressure of the tip part with the floor surface, thereby reducing the load when the tip part slides against the floor surface.

[0009] In the door-side member of the door stop device, the abutment portion may be provided so as to protrude downward from the lower end of the hinged door.

[0010] The door-side member of the door stop device may further include an adjustment portion for adjusting the height position of the abutting portion. [Effects of the Invention]

[0011] The door-side member of the door stop device of the present invention can suppress damage to the floor surface. [Brief explanation of the drawings]

[Figure 6] 2 is a cross-sectional view taken along the line AA in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described below.

[0014] First, the configuration of a door stop device including a door-side member 100 according to this embodiment will be described with reference to FIGS.

[0015] The door stop device is provided to regulate the maximum opening amount of the hinged door 150 (see FIG. 1). In other words, the door stop device functions as a stopper for the hinged door 150. The hinged door 150 is provided to be rotatable by a hinge (not shown) and is configured to be able to open and close a door opening (not shown). The door stop device includes a door-side member 100 (see FIG. 1) provided at the lower end of the hinged door 150 and a floor-side member (not shown) provided on the floor surface.

[0016] The floor-side member is fixed to a predetermined position on the floor surface according to the maximum opening amount of the hinged door 150, etc. The floor-side member is formed to rise slightly from the floor surface, and is set at a height that does not interfere with the hinged door 150 so that the hinged door 150 can pass above, and is set at a height position where it will come into contact with an abutting portion 1 (described later) of the door-side member 100. Therefore, in the door stop device, the abutting portion 1 of the door-side member 100 comes into contact with the floor-side member, thereby restricting the opening of the hinged door 150.

[0017] The door-side member 100 is embedded in the hinged door 150 so as to be spaced apart from the floor surface. For example, the door-side member 100 is disposed on the door tip side of the hinged door 150. As shown in FIG. 3 , the door-side member 100 includes an abutting portion 1 that abuts against the floor-side member, an adjustment portion 2 for adjusting the height position of the abutting portion 1, and a housing 3 that houses the adjustment portion 2.

[0018] [Case] The housing 3 is configured so that the contact portion 1 protrudes downward (in the Z2 direction) from the lower end. As shown in Fig. 4, the housing 3 includes a case 31 and covers 32 and 33. For example, the housing 3 is configured so that the cover 32 is exposed at the door tip side of the hinged door 150.

[0019] The case 31 is formed in a substantially rectangular box shape with an open bottom end face. The width direction (Y direction) of the case 31 is smaller than the length direction (X1 and X2 directions) and the height direction (Z1 and Z2 directions). Support holes 311 are formed in both end faces 31a of the case 31 to rotatably support the feed screw 21 (described later) of the adjustment unit 2.

[0020] The case 31 is also formed with a pair of mounting holes 312 for mounting the cover 32, and a pair of mounting holes 313 for mounting the cover 33. The pair of mounting holes 312 are located at both ends in the height direction at one end in the length direction (end on the X1 direction side). The pair of mounting holes 313 are located at both ends in the length direction at the bottom end (end on the Z2 direction side).

[0021] The cover 32 is configured to be attachable to one of the end faces 31a of the case 31 (the end face 31a on the X1 direction side). The cover 32 is formed with a screw arrangement hole 321 in which the feed screw 21 is arranged. The cover 32 is formed with a pair of engagement claws 322, which are arranged at both ends in the height direction.

[0022] The cover 33 is configured to be attachable to the lower end surface of the case 31. That is, the cover 33 is provided to close the opening of the case 31. The cover 33 is formed with a contact portion arrangement hole 331 in which the contact portion 1 is arranged. The cover 33 is formed with a pair of engagement claws 332, which are arranged at both ends in the longitudinal direction.

[0023] 5, in the housing 3, the cover 32 is attached to the case 31 by engaging the engaging claws 322 with the mounting holes 312. In addition, the cover 33 is attached to the case 31 by engaging the engaging claws 332 with the mounting holes 313.

[0024] [Adjustment section] As shown in FIG. 4, the adjustment unit 2 includes a feed screw 21, a slider 22 that is moved in the length direction by the feed screw 21, and an elevating component 23 that is raised and lowered by the movement of the slider 22.

[0025] As shown in FIG. 5 , the lead screw 21 is inserted into a support hole 311 in the case 31 and is rotatably supported in the support hole 311. The lead screw 21 has a shaft portion 211 and a head portion 212. A male thread (not shown) is formed on the outer peripheral surface of the shaft portion 211. The head portion 212 has, for example, a cross hole formed therein. The head portion 212 is exposed through a screw arrangement hole 321 in the cover 32. This allows the user to access the lead screw 21 and rotate the lead screw 21 using a screwdriver (not shown).

[0026] The slider 22 is formed with an insertion hole 221 through which the shaft portion 211 of the feed screw 21 is inserted. An internal thread (not shown) is formed on the inner peripheral surface of the insertion hole 221. The internal thread of the insertion hole 221 and the external thread of the shaft portion 211 are screwed together. Furthermore, as shown in FIG. 4, the slider 22 is formed with a pair of engaging protrusions 222 that protrude outward in the width direction.

[0027] The lifting / lowering component 23 is inserted through the opening of the case 31 and is housed in the case 31 so as to be movable in the vertical direction (Z1 and Z2 directions). The lifting / lowering component 23 has a mounting plate 23a to which the abutment portion 1 is attached, and a pair of side plates 23b extending upward (in the Z1 direction) from both ends of the mounting plate 23a in the width direction. The dimensions of the mounting plate 23a are slightly smaller than the dimensions of the opening of the case 31, and the side plates 23b are disposed adjacent to the inside of the side surface 31b of the case 31. This allows the lifting / lowering component 23 to move vertically within the case 31, while preventing the lifting / lowering component 23 from moving in the length direction and width direction relative to the case 31.

[0028] An engagement hole 231 is formed in each of the pair of side plate portions 23b. The engagement hole 231 is formed to extend linearly and to be inclined with respect to the longitudinal direction. For example, the engagement hole 231 is inclined so that it is positioned lower as it moves toward one side in the longitudinal direction (the X1 direction side). As shown in FIG. 6, the slider 22 is disposed between the pair of side plate portions 23b, and the engagement protrusion 222 of the slider 22 is inserted into the engagement hole 231 of the side plate portions 23b. As shown in FIG. 4, the mounting plate portion 23a is formed with an annular protrusion 232 into which the abutment portion 1 is fitted. The annular protrusion 232 is disposed in the center in the longitudinal direction.

[0029] [Contact part] As shown in FIG. 5, the abutment portion 1 is attached to the lifting component 23 and is provided so as to protrude downward through the abutment portion arrangement hole 331 of the cover 33. Therefore, the abutment portion 1 is provided so as to protrude downward from the lower end of the hinged door 150 (see FIG. 1). In other words, the abutment portion 1 is provided in the gap between the hinged door 150 and the floor surface and is capable of abutting against a floor-side member. As shown in FIG. 4, the abutment portion 1 includes a cylindrical body 11, a tip part 12, a compression coil spring 13, a pin 14, a reinforcing member 15, and a buffer material 16. The compression coil spring 13 is an example of the "biasing member" of the present invention.

[0030] The cylindrical body 11 is made of, for example, resin, and is formed into a cylindrical shape so as to extend in the vertical direction. A flange 111 that protrudes radially outward is formed at the tip (lower end) of the cylindrical body 11. A vertically extending elongated hole 112 is formed near the tip of the cylindrical body 11. A pair of elongated holes 112 are provided so as to face each other in the width direction. The width of the elongated holes 112 is slightly larger than the diameter of the pin 14. As shown in FIG. 5, the base end (upper end) of the cylindrical body 11 is fitted into an annular protrusion 232 of the mounting plate 23a and is attached to the mounting plate 23a using, for example, a screw (not shown). A spring bearing portion 113 that supports the compression coil spring 13 is also formed at the base end of the cylindrical body 11.

[0031] The tip component 12 is made of, for example, resin, has a cylindrical shape, and is provided inside the cylindrical body 11. The outer diameter of the tip component 12 is slightly smaller than the inner diameter of the cylindrical body 11, allowing the tip component 12 to move up and down within the cylindrical body 11. As shown in FIG. 4 , a circular through-hole 121 is formed in the tip component 12 in the width direction. The inner diameter of the through-hole 121 is slightly larger than the diameter of the pin 14. The pin 14 is inserted into the elongated hole 112 of the cylindrical body 11 and the through-hole 121 of the tip component 12. Therefore, the tip component 12 and the pin 14 move together, allowing the tip component 12 to move up and down within the elongated hole 112 by the distance that the pin 14 can move. The length of the pin 14 is set to be approximately the same as the outer diameter of the cylindrical body 11.

[0032] 6, the compression coil spring 13 is disposed inside the cylindrical body 11 and is sandwiched between the spring bearing portion 113 of the cylindrical body 11 and the tip part 12. Therefore, the compression coil spring 13 is configured to bias the tip part 12 downward (in the Z2 direction).

[0033] The reinforcing member 15 is made of, for example, metal, and is provided to reinforce the cylindrical body 11. The reinforcing member 15 is formed in a cylindrical shape and configured to cover the outer peripheral surface of the cylindrical body 11. The cylindrical body 11 is inserted inside the reinforcing member 15, and the tip end (lower end) of the reinforcing member 15 is engaged with a flange 111 of the cylindrical body 11. This prevents the reinforcing member 15 from falling off the cylindrical body 11.

[0034] The cushioning material 16 is made of, for example, rubber, and is provided to absorb the impact when the contact portion 1 contacts the floor member. The cushioning material 16 is formed in a cylindrical shape and is configured to cover the outer circumferential surface of the reinforcing material 15. The reinforcing material 15 is press-fitted inside the cushioning material 16.

[0035] The tip part 12 of the contact part 1 is arranged so as to protrude downward from the tip (lower end) of the cylindrical body 11, and is configured so as to be able to retract upward against the biasing force of the compression coil spring 13. As a result, when the hinged door 150 tilts due to aging or the like and the tip part 12 comes into contact with the floor surface, the tip part 12 is able to retract upward.

[0036] -Adjustment of the height position of the contact part- In the door-side member 100 described above, when a user uses a screwdriver to rotate the feed screw 21 to one side, the slider 22 is moved to one side in the length direction (X1 direction), and the lifting component 23 is moved upward (Z1 direction). This causes the contact portion 1 to rise, and the amount of protrusion of the contact portion 1 from the housing 3 is reduced.

[0037] On the other hand, when the user rotates the feed screw 21 to the other side using a screwdriver, the slider 22 moves to the other side in the length direction (X2 direction), and the lifting component 23 moves downward (Z2 direction). As a result, the contact portion 1 moves downward, and the amount of protrusion of the contact portion 1 from the housing 3 increases.

[0038] -effect- In this embodiment, as described above, the tip part 12 is disposed so as to protrude downward from the lower end of the cylindrical body 11, and the tip part 12 can be retracted upward against the biasing force of the compression coil spring 13. With this configuration, when the hinged door 150 tilts due to aging or the like and the tip part 12 comes into contact with the floor surface, the tip part 12 is retracted upward, so that the contact pressure of the tip part 12 with the floor surface can be reduced. This reduces the load when the tip part 12 slides against the floor surface. Therefore, damage to the floor surface can be suppressed.

[0039] Furthermore, when the tip part 12 slides on the floor surface and generates a sliding sound, the user can recognize that the tip part 12 is in contact with the floor surface. In this case, the user can correct the inclination of the hinged door 150 or adjust the height position of the abutment part 1 so that the abutment part 1 does not come into contact with the floor surface.

[0040] In addition, in this embodiment, the housing 3 is embedded in the hinged door 150 and the abutment portion 1 protrudes downward from the hinged door 150, thereby improving the appearance compared to when the door side member is installed on the door surface.

[0041] In this embodiment, the height position of the contact portion 1 can be adjusted by providing the adjustment portion 2.

[0042] In addition, in this embodiment, the provision of the reinforcing material 15 and the buffer material 16 makes it possible to reinforce the contact portion 1 and also to mitigate the impact when the contact portion 1 hits the floor member.

[0043] -Other embodiments- It should be noted that the embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention should not be interpreted solely by the above-described embodiments, but should be defined by the claims. The technical scope of the present invention also includes all modifications within the scope and meaning equivalent to the claims.

[0044] For example, in the above embodiment, an example in which the adjustment unit 2 is provided is shown, but the present invention is not limited to this, and an adjustment unit may not be provided.

[0045] In addition, in the above embodiment, an example is shown in which the housing 3 is exposed at the leading edge of the hinged door 150, but this is not limited to this, and the housing may not be exposed at the leading edge of the hinged door as long as the feed screw is accessible.

[0046] In the above embodiment, the cylindrical body 11 and the tip component 12 may be made of the same material, or may be made of different materials. When the cylindrical body 11 and the tip component 12 are made of different materials, the tip component 12 may be softer than the cylindrical body 11.

[0047] In the above embodiment, an example in which the cushioning material 16 is provided on the contact portion 1 is shown, but this is not limiting, and the cushioning material may not be provided on the contact portion. In this case, it is desirable to provide the cushioning material on the floor side member. [Industrial Applicability]
