Description

  The present invention relates to a door stopper that prevents an opened door or doorknob from colliding with a wall surface.

  Regarding the door stopper of the present invention, the applicant previously proposed the door stopper of Patent Document 1. There, the door stopper is constituted by a stopper body fixed to a floor or a wall, and a wedge body detachably mounted on the stopper body. A base metal fitting is embedded in and fixed to the inside of a stopper body made of a rubber molded product, and a screw hole is formed vertically in the center of the metal fitting. The door stopper can be fixed to the floor by screwing the base fitting into the anchor bolt fixed to the floor.

  In the present invention, for example, a door stopper is constituted by a base body fastened and fixed to a wood floor with a screw, an adapter screwed to the base body, and a stopper body attached to and detached from the adapter. A door stopper made of individual parts is known from U.S. Pat. There, a door stopper is configured by the base body, the stopper body, and the adapter mounted inside the stopper body. The base body integrally includes a disc-like seat and a screw provided at the center of the seat. The stopper body is formed of a rubber molded product, and the adapter is formed of hard resin or metal, and a screw hole is formed in a non-penetrating manner in the central portion thereof. A ring-shaped rib is provided on the inner surface of the stopper body, and a circumferential groove is formed on the circumferential surface of the adapter, and the stopper body is integrated with the adapter by engaging the rib with the circumferential groove.

  Patent Document 3 discloses a door stop (door stopper) configured by a rectangular solid contact portion made of a resin molded product having elasticity and a metal installation portion. Since it is necessary to use some fasteners in order to fix the door stop on the floor surface, the door stop of Patent Document 3 can also be said to be a door stopper formed of three parts. The installation portion is provided with a square seat plate portion and a square cylindrical tubular wall portion. By engaging the projection provided on the inner surface of the contact portion with the groove provided on the peripheral surface of the cylindrical wall portion, the contact portion and the installation portion are integrated, and in this state, the seat plate portion of the installation portion The circumferential surface of the lower part of the contact part is exposed.

  A similar door stop (door stopper) can also be found in US Pat. In this case, the door contact is constituted by a rectangular door contact main body, a floor seat plate, and a buffer sandwiched between the two. The floor plate integrally includes a square screw seat and a stepped bracket portion provided on the upper surface of the screw seat. In use, the floor plate is fastened to the wood floor with three screws, and the door contact main body is engaged with the bracket, and then both are fastened with the screw screwed into the bracket from the front of the door contact main body. . A stop ring is tiltably supported on the upper surface of the door holder main body, and the door can be held in the open position by hooking the ring on a seat fixed to the door.

Patent No. 5441263 (paragraph number 0027, FIG. 9) Design registration No. 1405680 (reference drawing showing the mounting method) Design registration No. 1483658 (front central vertical enlargement reference cross section) Design registration No. 1517632 (Reference diagram showing the state of use)

  The door stopper of Patent Document 1 fixes a door stopper to a floor surface by screwing a base fitting embedded and fixed inside the stopper body into an anchor bolt. Therefore, when the stopper body is formed in a non-circular shape such as a rectangular solid or an oval, or when a contact portion for receiving the door is provided on a part of the circumferential surface of the cylindrical door stopper, etc. It may not be possible to optimize the posture of the door stopper fixed to the. The attitude of the door stopper when the base metal fitting is screwed into the anchor bolt to the end depends on the screwing situation of the base metal with respect to the anchor bolt, and the attitude of the door stopper can not always be constant.

  In that respect, in the door stopper of Patent Document 2, the stopper main body is formed in a shape in which the upper part of the dodecagonal pillar is narrowed in a hemispherical shape, so the attitude when the stopper main body is screwed into the adapter has some dispersion It can be used without any problem. In addition, when the stopper main body is attached to the adapter, the entire outer surface of the adapter formed of hard resin or metal is covered with the stopper main body, so that the appearance of the door stopper can be made clear. However, since the stopper body is formed of a rubber molded product, even if the color and shape of the door stopper are changed to make the series commercially available, only uniform texture can be exhibited, and it is difficult to develop a product series full of interest. is there.

  In the door contact of Patent Document 3, the metal installation portion is configured of a square seat plate portion and a square cylindrical tubular wall portion. Therefore, it is difficult to cope with the case where it is desired to form the contact portion in a cylindrical shape, for example. If the contact portion is formed in a cylindrical shape, the four corners of the square seat plate portion protrude outside the contact portion. In order to avoid this, the diameter of the contact portion needs to be equal to or larger than the diagonal dimension of the seat plate portion, and the contact portion becomes abnormally large. Further, the contact portion is formed in a rectangular parallelepiped shape, and the peripheral surface of the seat plate portion of the installation portion is exposed at the lower portion of the contact portion in the use state. Therefore, there is a risk of injury in the case of accidental kicking.

  Since the door contact of Patent Document 4 fixes the door contact main body by screwing a screw from the front side of the door contact main body to the bracket portion of the floor seat plate, the operation head of the screw is exposed to the front of the door contact main body. Unavoidable. Therefore, there is a possibility that the door stop body may be removed due to mischief. Moreover, like the door stop of Patent Document 3, there is a possibility that the door stop main body fixed to the floor may be accidentally kicked.

  As described above, the conventional door stopper can not optimize the posture of the door stopper fixed to the floor surface, it is difficult to develop a diverse product series with great interest, and the anti-tamper measures and safety are sufficiently considered. There is room for improvement in terms of not being done. Also, in most cases, after the door stopper is installed at a predetermined position, for example, the stopper main body is worn and deteriorated and continues to be used as it was initially installed, so it is easy to get bored, fresh impression and new It was difficult to reveal an impression. Furthermore, when replacing a door stopper that has become tired, it is necessary to replace all of the stopper main body, the adapter and the base body, which increases the cost of replacement, and every time the door stopper is replaced There was a problem in that it was necessary to fasten the base body and the floor surface was damaged.

Furthermore, when replacing the stopper main body 3, parts other than the stopper main body 3 such as the screw base 1 and the boss body 2 can be used as they are, so the cost required for replacing the door stopper can be reduced. In the case where the screw base 1 is fastened and fixed to a wood floor, there is an advantage that the damage to the floor can be minimized.

  When the stopper main body 3 is made of the cushioning body 28 made of rubber, which is fixed to the outer surface of the exterior body 4, the cosmetic cap 5, and the cosmetic cap 5, and the cosmetic cap 5 is made of wood or plastic material, color tone or appearance shape Alternatively, since a variety of door stoppers can be provided by a combination of differences in texture, it is possible to develop an interesting product series. According to such a door stopper, since the user can select a desired door stopper from the product series according to the condition of the floor surface, the surrounding area of the door panel P, etc., the degree of freedom in selection can be expanded. In addition, the atmosphere and the impression around the door can be made new by replacing the door stopper in accordance with the change of the season, the change of the indoor furniture, and the like. Further, in the state where the cosmetic cap 5 is attached to the exterior body 4, the cosmetic cap 5 covers the outer surfaces of the screw base 1, the boss 2 and the exterior body 4 and abuts on the floor surface. Even if there is a problem, it can improve safety without injury. The rubber shock absorber 28 elastically deforms when the door panel P collides to absorb and absorb the shock. Further, the exterior body 4 to which the cosmetic cap 5 is attached is also partially elastically deformed to help reduce the impact impact of the door panel P. Therefore, even if the door panel P collides with the door stopper, no large collision noise is generated, and the door panel P or the door stopper is not damaged.

  According to the stopper main body 3 configured by integrating the cosmetic cap 5 and the bottomed cylindrical exterior body 4 with an adhesive, it is possible to save time and labor for assembling the respective members 4 and 5 at the construction site, and further, the exterior body There is no fear that the pair of cosmetic cap 5 and the cosmetic cap 5 may be mistaken. In addition, since the cosmetic cap 5 and the exterior body 4 can be simultaneously attached to and removed from the boss body 2, it is possible to save time and labor during construction or replacement, and the exterior body 4 and the cosmetic cap 5 can be properly attached to the boss body 2. It can be worn. When the door panel P collides, the buffer 28 elastically deforms to reduce the impact. In addition, a part of the exterior body 4 integrated with the cosmetic cap 5 is also elastically deformed to reduce the collision impact of the door panel P. Therefore, the impact impact of the door panel P can be effectively absorbed by the impact absorbing action of the buffer 28 and the impact absorbing action of the exterior body 4.

  When the upper shaft 18 and the lower shaft 19 of the boss 2 receive the inner peripheral surface of the mounting hole 21 of the outer body 4 in a state where the outer body 4 is attached to the boss 2, the rubber outer body 4 is Can be backed up by the metallic boss body 2 so that the postures of the exterior body 4 and the stopper main body 3 can always be maintained in an appropriate state.

  When the door panel P subjected to the opening operation is received by the buffer body 28, the elastic wall 32 is elastically deformed so as to be crushed and the collision impact of the door panel P is absorbed. The elastic wall 32 returns to the state before being elastically deformed at the same time as the door panel P separates from the buffer 28. The impact received by the buffer body 28 also acts on the exterior body 4 via the bonding portion of the cosmetic cap 5 and absorbs impact force by elastically deforming a part of the exterior body 4. Therefore, the impact impact of the door panel P can be absorbed by the impact absorbing action of the buffer 28 and the impact absorbing action of the exterior body 4. Therefore, even if the door panel P collides with the door stopper, no large collision noise is generated, and the door panel P or the door stopper is not damaged.

  When replacing the stopper main body 3, the cosmetic cap 5 is tilted to form a gap between the lower surface of the cap 5 and the floor surface, and the flat head screwdriver inserted into the gap is used as a forceps to make the cosmetic cap 5 The lifting operation is performed to separate the rib 22 from the retaining step 17 while elastically deforming the rib 22. The stopper main body 3 can be removed from the boss 2 by pulling the cosmetic cap 5 upward with all the ribs 22 separated from the retaining step 17 and received by the upper shaft 18. In a state in which the rib 22 is elastically deformed and received by the upper shaft portion 18, the cylindrical wall of the exterior body 4 bulges in the form of outward swelling, but this swelling deformation is allowed to facilitate removal of the stopper main body 3 In order to achieve this, a gap E1 is provided between the cylindrical wall of the exterior body 4 and the inner surface of the cosmetic cap 5. Finally, a new stopper main body 3 is mounted on the boss body 2 and the rib body 22 is dropped into and engaged with the engagement groove 16 and the locking step 17 in the manner described above, and the buffer body 28 is released.

Therefore, the impact deformation of the door panel P can be absorbed by the buffer body 28 being compressed and deformed, and a part of the exterior body 4 can be elastically deformed to absorb the impact force. Therefore, as in the previous embodiment, even if the door panel P collides with the door stopper, no large collision noise is generated, and the door panel P or the door stopper is not damaged. In addition, even if the cosmetic cap 5 is accidentally kicked, the safety can be improved without being injured, and in particular, when the buffer 28 is kicked, the buffer 28 is elastically deformed. Since the shock can be mitigated, the safety can be further improved. In addition, since the cylindrical wall and the flange wall 24 of the exterior body 4 are elastically deformed to be absorbed and absorbed when the cosmetic cap 5 is kicked, the pain associated with the kicking can be alleviated.

(Example 4) FIG. 11: shows Example 4 which changed a part of door stopper. In this case, the decorative cap 5 made of woodwork is formed in a cylindrical shape, a part of the cylindrical peripheral wall is omitted, and the omitted opening part is closed with a plate-like buffer body 28. The circumferential surface of the buffer body 28 is formed of a partial arc surface continuous with the circumferential surface of the cosmetic cap 5. Also in this embodiment, the stopper body 3 is configured by integrally fixing the exterior body 4, the cosmetic cap 5, and the buffer body 28 with an adhesive.

Example 5 FIG. 12 shows Example 5 in which a part of the door stopper is changed. There, a cosmetic cap 5 made of woodwork was formed in a house shape, and one buffer body 28 was fixed at the front end thereof. Further, the vertical length of the cosmetic cap 5 is increased to cope with the case where the gap between the door panel P and the floor surface is large, and the fixing position of the buffer 28 is shifted upward. The mounting hole 27 was formed at the front and back center of the cosmetic cap 5. The buffer body 28 was constituted by the shaft portion 29 and the contact portion 30 in the same manner as the buffer body 28 of the first embodiment. Also in this embodiment, the stopper body 3 is configured by integrally fixing the exterior body 4, the cosmetic cap 5, and the buffer body 28 with an adhesive. As can be understood from the above embodiments, the buffer 28 may be fixed to the circumferential surface of the cosmetic cap 5 that faces the door panel P that has been opened.

Sixth Embodiment FIGS. 13 to 15 show a sixth embodiment in which a part of the door stopper is changed. In this case, the decorative cap 5 made of woodwork is formed in a cylindrical shape as in the fourth embodiment, but the center position of the mounting hole 27 is eccentrically moved away from the adhesive surface of the buffer 28 to adhere the buffer 28. A wood wall 42 is formed between the surface and the mounting hole 27. Moreover, although the exterior body 4 is formed in the bottomed cylindrical shape of the same diameter as the flange wall 24 in basic shape, the flat surface 43 is formed in four places of the outer peripheral surface of a cylinder wall, and between the adjacent flat surfaces 43 Is provided with a partially arcuate engagement surface 44. In the state where the exterior body 4 is adhered to the decorative cap 5, the four engaging surfaces 44 and the peripheral surface of the flange wall 24 are adhered and fixed to the mounting hole 27, and a gap E1 is formed between the flat surface 43 and the mounting hole 27. It is formed. In this embodiment, the rib 22 is provided at two points on the opposing surface of the mounting hole 21 so that the stopper body 3 can be easily attached to and detached from the boss 2. The flat surface 43 may be provided at at least two places.

  As described above, when the center position of the mounting hole 27 is eccentrically formed to form the wood wall 42 between the adhesive surface of the shock absorber 28 and the mounting hole 27, the impact force acting on the shock absorber 28 can be It can be transmitted to the cosmetic cap 5 directly and in a dispersed state through 42. Further, since the cosmetic cap 5 and the exterior body 4 can be integrated more firmly by bonding and fixing the four engaging surfaces 44 to the mounting hole 27, the impact force acting on the cosmetic cap 5 can be obtained from the engaging surface 44. By transmitting to the cylindrical wall of the exterior body 4 and elastically deforming the cylindrical wall, the impact force can be mitigated and absorbed more effectively. Furthermore, even when the cosmetic cap 5 made of woodwork is contracted and deformed due to aging, the contracted deformation can be absorbed by the gap E1, so that the stopper body 3 can be attached to and detached from the boss body 2 reliably and simply.

The door stopper according to the sixth embodiment can be implemented in the following form.
The central position of the mounting hole 27 formed in the cosmetic cap 5 is eccentric from the central position of the cosmetic cap 5,
A buffer 28 is fixed to the circumferential surface of the cosmetic cap 5 on the opposite side of the mounting hole 27 in the eccentric direction, and a wood wall 42 is formed between the buffer 28 and the mounting hole 27,
Flat surfaces 43 are formed at a plurality of locations on the outer peripheral surface of the cylindrical wall of the exterior body 4 formed in a bottomed cylindrical shape, and a partially arc-shaped engaging surface 44 is provided between adjacent flat surfaces 43,
In the state where the exterior body 4 is adhered to the cosmetic cap 5, the plurality of engagement surfaces 44 are adhered and fixed to the mounting hole 27, and a gap E 1 is formed between the flat surface 43 and the mounting hole 27.

Seventh Embodiment FIGS. 16 and 17 show a seventh embodiment in which a part of the door stopper is changed. There, as in the sixth embodiment, the center position of the mounting hole 27 of the cosmetic cap 5 made of woodwork is eccentric to the side away from the adhesive surface of the buffer 28 so that the adhesive surface of the buffer 28 and the mounting hole 27 The wood wall 42 was formed in between. Moreover, although the exterior body 4 is formed in a bottomed cylindrical shape, the longitudinally long engagement rib 45 is provided in eight places of the outer peripheral surface of a cylinder wall at fixed intervals, and the partial arc-shaped engagement surface of each rib 45 44 was engaged with the mounting hole 27. The cross section of the engagement rib 45 is formed like a cocktail glass so that the engagement rib 45 can be elastically deformed with a smaller force.

  As described above, when the cosmetic cap 5 is received by the eight engagement ribs 45, the plurality of engagement ribs 45 are elastically deformed even when an impact is applied to the peripheral surface of the cosmetic cap 5 other than the buffer 28. Impact can be effectively mitigated and absorbed. Further, when the cosmetic cap 5 is attached or detached, the engagement rib 45 is elastically deformed to absorb the elastic deformation of the rib 22 outward, so that the stopper main body 3 can be easily attached to and detached from the boss 2 . Furthermore, even when the cosmetic cap 5 made of woodwork is contracted due to aging, the elastic deformation of the engagement rib 45 can absorb the contracted deformation, so that the cosmetic cap 5 can be prevented from breaking.

Reference Example 1 FIGS. 18 and 19 show Reference Example 1 in which a part of the door stopper is changed. In this case, the cosmetic cap 5 is omitted, and the stopper main body 3 is constituted only by the rectangular parallelepiped exterior body 4 made of a rubber molded product so that the cylindrical wall of the exterior body 4 doubles as the buffer 28. Further, in the state where the exterior body 4 is mounted on the boss body 2, the gap E 2 is formed between the upper surface of the boss body 2 and the upper wall of the exterior body 4. The flange wall 24 is omitted to make the outer appearance of the stopper body 3 simple.

  As described above, when the stopper main body 3 is configured only with the exterior body 4, the cost of the door stopper can be reduced by the amount of omission of the cosmetic cap 5. Further, the impact of the door panel P can be absorbed by directly receiving the impact of the door panel P by the cylindrical wall of the exterior body 4 backed up by the boss body 2 and the cylindrical wall is elastically deformed. Therefore, as in the embodiments described above, no loud collision noise is generated when the door panel P collides with the door stopper, and the door panel P or the door stopper is not damaged. Further, since the entire outer surface of the metallic boss body 2 and the base seat 7 is covered with the exterior body 4, even if the exterior body 4 is accidentally kicked, the cylindrical wall is elastically deformed to reduce the impact. As it can, it can improve safety.

  Since the gap E2 is provided between the upper surface of the boss body 2 and the upper wall of the exterior body 4, even if the upper wall of the exterior body 4 is accidentally stepped on, the upper wall of the exterior body 4 is elastically deformed to reduce the impact. it can. Since the stopper main body 3 configured by the exterior body 4 may directly attach and detach the exterior body 4 to and from the boss body 2, the exterior body 4 can be attached and detached more easily than the stopper main body 3 provided with the cosmetic cap 5. In addition, since 4 to 6 kinds of color variations are prepared for the exterior body 4 made of a rubber molded product, if a plurality of exterior bodies 4 are purchased, it is possible to change the season or change the indoor furniture etc. Accordingly, the stopper body 3 can be freely replaced.

There, the cosmetic cap 5 is omitted, and the stopper main body 3 is constituted only by the cylindrical exterior body 4 made of a rubber molded product so that the cylindrical wall of the exterior body 4 doubles as the buffer 28. Although not illustrated , also in this reference example , a gap E2 is provided between the upper surface of the boss 2 and the upper wall of the exterior body 4. The flange wall 24 is omitted to make the outer appearance of the stopper body 3 simple.

  As can be understood from the above embodiments, the external shape of the stopper body 3 can be formed into an arbitrary shape, and the screw base 1 and the boss body 2 can be commonly used for all the door stoppers. Further, since the installation posture of the stopper body 3 is specified by the base seats 7 and 36 fixed to the floor, the door stopper can always be fixed to the floor with a suitable posture regardless of the difference in the external shape of the stopper body 3. In addition, the material for forming the exterior body 4 and the cosmetic cap 5 is formed of a rubber molded product, a woodwork product, a plastic molded product, or a variety of color variations are prepared to diversify the door stoppers and make the product interesting You can expand the series. The outer surface shape of the exterior body 4 can be formed in a spline shaft shape, and the number of engaging surfaces 44 in that case can be 4 to 8.

  Although the rib 22 is intermittently provided in the above embodiment, the rib 22 may be formed of a circumferential rib. The outer package 4 and the buffer 28 may be made of an elastomer such as natural rubber or synthetic rubber. The exterior body 4 does not need to be a bottomed cylindrical shape, and may be formed of a cylindrical body whose upper and lower surfaces are open. In that case, the flange wall 24 may be formed so as to overhang at the upper end of the cylindrical wall to increase the bonding area to the cosmetic cap 5. The boss body 2 may be formed into a polygonal axis, and the engaging groove 16 may be formed into a round axis at the upper and lower middle portions thereof, in addition to the circular axis.

  The buffer body 28 may be formed in a ring shape or a round cylinder shape, and may be attached to the peripheral surface of the cylindrically formed cosmetic cap 5. If a decorative ring or hook is provided on the cosmetic cap 5 and the hooking metal is fixed at the corresponding position of the door panel P, the ring or hook is locked to the hooking metal of the door panel P received by the stopper body 3 Thus, the door panel P can be held in the open position. The boss body 2 and the screw shaft 8 can be prepared according to the difference in screw standard such as metric screw or inch screw. Moreover, the boss body 2 can be fixed to a floor surface using the existing anchor bolt by preparing multiple types of boss bodies 2 in which the screw specifications and screw sizes of the screw holes 15 are different. In the case of a door stopper applied to a wood-based floor surface, the screw shaft 8 provided integrally with the boss body 2 may be screwed into the screw hole 15 formed in the base seat 7 and fixed to the screw base 1 . In place of the engagement groove 16, an engagement rib (a boss side engagement portion) is formed circumferentially on the circumferential surface of the boss body 2, and engaged with the engagement rib on the inner surface of the mounting hole 21 of the exterior body 4. It is possible to form a mating engagement recess (outer body side engagement portion).
