Description

[Detailed Description of the Invention] The present invention relates to the mounting structure of a door stop, and in particular, the support shaft, which is screwed into the anchor bolt on the floor while the buffer rubber is disposed in the direction of the fully open door, is prevented from accidentally rotating due to external force. This invention relates to a mounting structure for a door stop that is strongly tightened and fixed using a threaded screw means.

The opened door is stopped in the open position while absorbing all the shock,
Furthermore, it is preferable for the doorstop, which is held in the open position by a hanging ring, to be fixed by screwing using all the members in the assembly process, from the viewpoint of simplicity and quickness of the installation work. Conventional doorstops of this kind are either attached to anchor bolts on concrete floors or walls, or attached to bolts attached to walls made of wood or synthetic resin through seat plates secured with screws. Attach the door stop support shaft to the above-mentioned anchor bolt through the screw hole? When screwed in through the support shaft and strongly tightened to the entire concrete surface of the lower end of the support shaft, the direction of the buffer installed perpendicular to the support shaft is almost always not perpendicular to the open door surface, and the tightening is difficult. The direction of the shock absorber was adjusted by rotating the support shaft in the direction of loosening it. In a door stop whose support shaft is loosened even slightly, the direction of the shock absorber is easily deflected by the impact force of opening the door. Such a deflection effect of the support shaft is the same in the case of a bolt interposed in a screw-fixed seat plate.

In order to solve all the defects like the one above, Jikoko 56-153
Technical means such as those described in Publication No. 40 have been proposed. This is proposed by drilling a polygonal square hole in the center of the screw seat plate and making the neck of the bolt inserted into this square hole a square surface to completely prevent the bolt from rotating or loosening. has been done.

however.

j sitting board temporarily +i! After setting the fl and tightening the support shaft to the bolt.

Even if the support shaft is loosened and corrected by the deflection angle of the shock absorber relative to the door, it is almost impossible to manually position the shock absorber in a direction orthogonal to the door, and the tightening support is almost impossible. The situation was such that the shaft had to be loosened and adjusted somewhat. Even if the arrangement was adjusted to be accurate, the temporary fixing work would have to be repeated several times.

The present invention eliminates the above-mentioned defects, and its gist is that regardless of whether the bolt is inserted in the anchor bolt or the seat plate fixed with screws, the door that is screwed to the bolt, etc. The lower end of the hit shaft is fully threaded with a nut,
After the lower end surface of the support shaft that is screwed into contact with the concrete surface or the seat plate is tightened, it is rotated in the opposite direction so as to loosen by the deflection angle of the shock absorber. Then, the nut is strongly rotated and tightened from the entire concrete surface to the seat plate surface. Due to the structure and operation of the present invention, there is no need for complicated alignment operations of the shock absorbers, and the entire shock absorber can be arranged in a predetermined direction with a simple screwing operation, while being prevented from being rotated due to external impact force. The door stop support shaft can be fully attached. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is a door stop according to the present invention in which a shock absorber 3 made of a rubber material or the like is fixed horizontally from the upper end of a support shaft 2 that stands up on the floor surface, giving the entire structure an inverted shape. . The doorstop attached to the anchor bolt 5 on the concrete floor 4 is shown in FIG. Figure 3 shows a door stop 6 in which a support shaft 2 and a buffer body 3' are connected and fixed in a straight line, and the door stop 6 is usually attached to a wall frame or core 7 made of wood 1 and synthetic resin material. In this case, the bolt 5', which is not embedded, is interposed in the seat plate 9, which is fixed with full screws 8, and the support shaft 2 of the door stop is screwed onto this bolt 5'. However, if the walls are made of concrete and the floor is made of wooden boards, etc., the bolt members will be replaced accordingly.

The support 1liIII2 used in FIGS. 2 and 3 is made of a metal material and has a cylindrical shape, and a 74-hole 10 is drilled in the axial direction at its base end for screwing into the anchor bolt 5 or bolt 5'. It is set up. Further, a thread 12 is carved on the outer periphery of the base end of the support shaft 2 over a length corresponding to the thickness of the oak 11, and the diameter of this thread 12 portion is made smaller than the diameter of the support shaft 2. . This is to make the diameter of the nut as small as possible so that it can be housed compactly within the hemispherical cosmetic cup.

A hanging ring 14 is rotatably attached to the tip of the support shaft 2.

When this hanging ring 14 is rotated and its tip is placed on the front end side of the buffer body 3, the hanging ring is fastened to a cast metal (not shown) fixed to the open door. This is for locking. Therefore, if the door stop support shaft rotates inadvertently due to the impact of opening the door, the locus of rotation of the hanging ring will be deflected (
2 Seat plate 9 that cannot be fastened to the cast metal of the door
is in the shape of a disk, and is fixed to the floor or wall with screws 8 through screw insertion holes drilled around its periphery. A hole 15 having a diameter roughly equal to the diameter of the anchor bolt 5 is provided in the center of the seat plate 9. Furthermore, in FIG. 3, a circular stepped portion 17 is press-formed to accommodate the flat chain portion 16 of the belt 5', and a concave portion 18 is formed.
will be established.

This seat plate 9 is used for the anchor bolt 5 of the door stop shown in FIG.

The operation of the present invention configured as above will be explained.

12 threads 12 sufficiently. - After inserting the seat plate 9 into the anchor bolt 5 of the concrete floor surface 4, fix it to the floor surface with screws 8. Once prepared in this way, the support shaft 2 is screwed onto the anchor bolt 5.
When the lower end surface of the support shaft 2 contacts the upper surface of the seat plate 9, the support shaft 2
While rotating slightly in the opposite direction, place the buffer rubber 3 in the direction orthogonal to the open door surface. Then, firmly tighten the nut to the seat plate 9 by turning it with a tool such as a wrench. When the nut rotates further, the pivot shaft 2 no longer rotates due to the external impact force.

Then, the decorative cover 13 is attached to the seat plate 9.

As shown in FIG. 1, the decorative cover 13 has a

The entire seat plate 9 with the stepped portion 17 was used, but this is a seat plate that is attached to a bolt having a crease. There is no need to use one that has one. However, if the seat plate is not fully used, the nut 11 will directly press the concrete face metal and crush it, making it impossible to maintain the fully tightened and fixed state.

The door stop 6 shown in FIG. 3 is secured to a wooden wall surface, 11J wood 7, with a seat plate 9 with bolts 5' interposed therebetween using screws 8.

(position shown in Figure 3) -! , to reverse rotation. Then, turn it with a Natsu hll metal tool and firmly tighten and fix it to the seat plate 9.

Thereafter, the decorative cover 13 may be attached to the seat plate 9.

The present invention, which has the above-mentioned effects, is an oak screwed onto a support shaft.
When tightened to the fixed seat plate, the groove surface of the support shaft separates from the CJJ plate surface, but the frictional force between the threads of the support shaft and the nut, and the frictional force between the nut and the seat plate are extremely strong and can be buffered. Even if the door opening impact force is applied to the rubber, the support shaft will still rotate.

Furthermore, in addition to visually aligning the support shaft screwed with the bolt in the direction of the shock-absorbing metal door, it is also possible to firmly secure the door stop simply by slightly turning the nut. As shown in the figure, there is no need to repeatedly temporarily fix the support shaft or seat plate, and the installation does not require precision or complexity.

Furthermore, the mounting structure of the door stop according to the present invention is not only applicable to those fixed to the building body with the full seat plate of the head bolt,
It is extremely versatile because it can be completely attached to the door stop without causing any problems even with bolts that can be processed into bolt members at the construction site, such as anchor bolts that have already been buried.
