Description

[Detailed description of the invention] A. Purpose of the invention [Field of industrial application] The present invention relates to a floor-mounted door stop with a non-directional anti-tilt mechanism.

[Conventional technology]

Conventionally, floor-mounted door stops installed on the floor have an inverted L-shape with a vertical shaft part that stands on the floor and a horizontal door stop part that contacts the outside surface of the opening side of the door perpendicularly at the opening stop position of the door. is formed. When installing such a door stop on a concrete floor, it is easier to install one anchor bolt in the concrete floor and screw the vertical shaft part into this anchor bolt through its female threaded hole. Preferable because of speed and speed. However, if the screws are simply screwed in as described above, it is almost impossible for the door stop to stop with the direction perpendicular to the contact surface of the door in the open stop position.For this reason, a spacer of the required thickness is attached to the anchor bolt. The direction of the door stop is adjusted by inserting an insert or by screwing in an adjustment nut, but although this adjustment is quite troublesome, it is still possible to accurately set the direction of the door stop to the door contact surface. It was difficult to adjust it vertically.

For this reason, doorstops with non-directional disc-shaped doorstops that eliminate the directionality of the doorstop, for example,
It is disclosed in Publication No. 55-92853. This invention is characterized in that a support rod is protruded from the base, and a cushion portion is provided around the tip of the support rod, and is further provided with a anti-slip member of a known construction. The anti-slip member is formed of a wire rod into a rectangular shape, and its base end is pivoted to a collar that is rotatably fitted to the support rod in close proximity to the lower part of the cushion portion, and is pivoted about the axis of the support rod. It is rotatable in two directions: in the circumferential direction and in the vertical plane including the coaxial line.

[Problem that the invention attempts to solve]

Normally, this anti-swaying member hangs down along the support rod, and when the door is opened and the door is stopped from swinging, the anti-swaying member is rotated toward the door and its free end is lifted and dropped onto a hook provided on the door. Multiply. In this case, the anti-slip member and the door-side hook are located below the cushion portion, which has a larger diameter than the support rod, and are difficult to see directly, making it surprisingly time-consuming to latch them. In addition, especially in the type where the support rod is short and the anti-slip member is perpendicular to the floor surface, when the door is opened, the free end of the anti-slip metal that rotates toward the door will bite into the gap between the bottom of the door and the floor. The door stop part does not come into contact with the door surface when the door is pushed in, making it more difficult to latch the door, and the door and the locking fitting may be damaged together.

In view of the above, the present invention has been developed by forming the door stop part non-directionally so that it can be fixed easily and quickly without worrying about the mounting direction, and the anti-tagging member and the hook on the door side can be fixed easily and quickly. To provide a floor-mounted door stop with a fan stopper that can be easily latched while looking directly at both sides, and in which a fan stopper member does not interfere with the door and the door stop part when the door is fully opened.

B. Structure of the invention [Means for solving the problem] In order to achieve the above object, in the present invention, a vertical A doorstop part 3 made of a thick disc-shaped elastic material with a diameter larger than that of the shaft part 2 is joined with both axes aligned, and a anti-slip member 8 is provided which engages with a receiving member 10 provided on the door 9 side. In the floor-mounted door stops 1 and 1' with a anti-tilting mechanism, the anti-tilting member 8 has a long hole 8a in the longitudinal direction at the base and a latch part 8b that engages with the receiving member 10 on the door 9 side at the tip. When the long hole 8a is loosely fitted into the pin 7 protruding from the center of the upper surface of the door stop 3, and the anti-slip member 8 is pulled out along the long hole 8a toward the outer circumference of the door stop 3. The locking part 8b is located outside the outer periphery of the door stop 3, and the tip of the anti-slip member 8 is located inside the outside periphery of the door stop 3 when pulled toward the center. It is.

〔Example〕

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

As shown in FIGS. 1 and 2, the main body of the door stop 1 according to the present invention has a cylindrical vertical shaft 2 formed of a rigid material such as metal, and an elastic material such as black rubber attached to the upper end of the door stop 1. A door stop part 3 formed in the shape of a thick disk having a diameter slightly larger than that of the vertical shaft part 2 is joined with both axes aligned. A female threaded hole 2a is formed in the axial center of the vertical shaft portion 2 to be screwed into an anchor bolt 5 installed in the concrete floor surface 4, and a disk-shaped washer 6 is attached to the lower end surface. A pin 7 integral with the vertical shaft part 2 is projected from the center of the upper surface of the door stop part 3, and a rectangular anti-slip member 8 made of a metal plate is attached to the pin 7. This anti-slip member 8 has a long hole 8a in the length direction at its base, and a hook hole (latching portion) 8b at its tip that engages with a hook 10a of a receiving member 10 attached to the door 9 side. The hole 8a is loosely fitted into the pin 7, so that the anti-slip member 8 can rotate around the pin 7 in the entire circumferential direction, and its tip can freely move up and down. When the locking member 8 is pulled out along the elongated hole 8a toward the outer periphery of the door stop 3, the locking hole 8b is located outside the outer periphery of the door stop 3, and conversely, when pulled toward the center, The dimensions of each part are set so that the tip of the anti-tagging member 8 is located inside the outer periphery of the door stop 3. Incidentally, a knob 8c is provided on the upper surface of the anti-slip member 8.

The receiving member 10 is formed into a substantially U-shape by a concave part 10b that receives the outer periphery of the door stop part 3 of the door stop 1, and a pair of legs 10c with bent left and right ends of the concave part 10b. The aforementioned hook 10a that engages with the locking hole 8b of the anti-slip member 8 is formed. This receiving member 10 is fixed at a predetermined position on the door 9 by one wood screw 11 inserted into the concave portion 10b, and at this time, a claw 10 formed at the tip of the leg portion 10c
d bites into the door 9 to prevent the receiving member 10 from rotating.

Fig. 3 shows a door stop according to the present invention for a wooden floor.The door stop 1' has a washer 6 firmly fastened to the vertical shaft part 2 with a plurality of bolts 12, and is installed around the periphery of the washer 6. It is adapted to be attached to a wooden floor surface 4' by inserting wooden screws 13 through a plurality of mounting holes 6a, and the other structure is the same as that for the concrete floor surface.

[Effect]

Next, the operation of the above embodiment will be explained.

When installing the doorstop 1 of the present invention on a concrete floor surface 4, anchor bolt holes of a predetermined size are drilled at predetermined positions on the concrete floor surface 4 using a concrete drill. Next, insert the anchor bolt 5 into this hole.
By inserting the anchor bolt and driving the center pin 5a, the lower part of the anchor bolt expands and bites into the concrete hole, so that the anchor bolt 5 is firmly erected on the floor surface 4. Next, the washer 6 is inserted into the anchor bolt 5, and the female screw hole 2a of the vertical shaft portion 2 of the rear door per 1 is screwed into the anchor bolt 5 to firmly fix the door per 1 to the anchor bolt 5. At this time, since the door stop part 3 is disc-shaped and has no directionality, the door stop 1 is casually attached to the anchor bolt 5 without paying attention to the direction at the stop position of the door stop part 3.
It can be screwed into place. i.e. 1 per door
can be firmly attached to the concrete floor surface 4 with one touch. And when door 9 is opened to the maximum, door 9
The concave portion 10b of the receiving member 10 is received by the door stop portion 3 of the door stop 1 in a cushioning manner, thereby preventing the door 9 from colliding with walls, furniture, etc. and damaging them. At this time, even if the anti-fanning member 8 happens to be pulled out toward the door 9 side, the anti-fanning member 8 is pushed along the elongated hole 8a to the outer periphery of the door stop part 3 by the receiving member 10, is received by the receiving member 10 in a cushioning manner without being interfered with by the anti-rolling member 8. When locking the door 9, pinch the knob 8c with your fingers, lift the tip of the locking member 8, and drop the locking hole 8b into the hook 10a of the receiving member 10. At this time, the locking member 8 and the hook 10a are located on the upper surface of the door stop 1 and can be seen completely directly, so this locking can be easily done without any confusion.

Even with the doorstop 1' for a wooden floor shown in Fig. 3, the doorstop 1' can be easily attached to the wooden floor 4' with the wood screws 13 without paying attention to the direction of the doorstop 3. .

C. Effects of the invention As described above, according to the invention, since the door stop is formed in the shape of a non-directional thick disk using an elastic material, there is no need to pay attention to the direction of the door stop with respect to the door surface. The door stop can be easily and quickly attached to the floor by a simple method such as screwing and fixing the vertical shaft portion to one anchor bolt installed in the floor. Moreover, since it is easier to manufacture and process than the conventional inverted L-shaped floor-mounted door stop, it can be provided at a lower price, and installation costs are also reduced.

In addition, since the anti-tilt fitting is located on the upper surface of the door stop, it can be easily engaged with the receiving member on the door side while directly viewing the anti-tilt member.

Furthermore, when the door stopper is pulled out toward the outer periphery of the door stop, the locking part that engages with the receiving member on the door side is located outside the outer periphery of the door stop, and conversely, when the door stop is pulled toward the center, the door stop is pulled out. Since the tip of the stopper member is located inside the outer periphery of the door stop, when the door is opened to its maximum extent, even if the anti-tick member happens to be pulled out in the direction of the door, the receiving member will keep it from elongating. The door stop is pushed through the hole to the outer periphery of the door stop, and the door stop is received by the receiving member in a cushioning manner without being interfered with by the anti-adjustment member, thereby preventing engagement between the anti-adjustment member and the receiving member. In addition, the door stop or the door is prevented from being damaged due to interference of the anti-tilting member.
