Nut sticker and door stopper using it {NUT STICKER AND DOOR STOPPER THEREOF}

The present invention relates to a nut sticker that provides a nut hole through which a bolt can be inserted into an entrance door, furniture, or general wall without drilling, and a door stopper installed on an entrance door using the nut sticker.

The hinged entrance door, which is generally installed at the entrance of an apartment or house, is a door closer that automatically closes the door by using hydraulic pressure between the door frame and the inside of the door to automatically close the door after it is opened to maintain security and protect privacy. will be installed. However, since there is a need to temporarily open the door for moving objects or ventilation, etc., a door stopper is installed on the inner lower part of the door to maintain the open state of the door with the door closer installed, allowing it to be opened at an angle desired by the user. The door can be kept open.

A door-stopper is generally installed on the lower inner side of the door to prevent it from closing in order to fix the swing-type door in the user's desired position while it is open, and temporarily fix the door's position using friction with the ground. It is a device that does this.

The most common form of this door stopper is a type installed on the lower inner surface of the door using a bracket (b) so that the horseshoe leg (a) can rotate, as shown in Figure 1 of the attached drawing. As shown in the drawing, this door stopper rotates the horseshoe leg installed on the inner side of the door at the point where the position of the opened door is to be fixed, and the pad (c) at the bottom of the horseshoe leg is brought into close contact with the ground, thereby creating friction between the pad and the ground. As a result, closing of the door is suppressed, making it possible to maintain the open state of the door (d).

Conventional general door stoppers had to support a door with a relatively large load, so unity with the door was important, so the door stopper was fixed to the door using fasteners such as bolts or pins. Since the fastener requires a hole in the door, there was a problem that the inner side of the door was damaged, and when the door stopper was separated from the door, the hole where the fastener was inserted was exposed, which spoiled the aesthetics.

Ultimately, a fastening means that could secure the door stopper without damaging the door was required.

2 to 5, the nut sticker 100 according to the present invention includes a thin plate-shaped adhesive sheet 110 with adhesive applied to one side, a nut 130 provided with a nut hole 131, and a nut The hole 131 is composed of a non-flexible panel-type holder 120 that surrounds the nut 130 so as to be open, absorbs it, accommodates it in the center, and is fused to the other side of the adhesive sheet 110. The nut sticker (100) is a nut hole (131) through which a bolt (B) can be inserted without directly drilling a door (D) that requires the installation of a door stopper, as well as other walls or furniture that require the installation of various accessories. generates. For this purpose, the adhesive sheet 110 of the nut sticker 100 is adhered to the door D, a wall, or furniture, and for this purpose, adhesive is applied to one side of the adhesive sheet 110. The adhesive hardens by reacting with certain substances or moisture in the air, so to prevent this, one side of the adhesive sheet 110 is covered and protected with release paper 140, and the release paper 140 is separated from the adhesive sheet 110 for use. . The composition of the adhesive varies greatly depending on the required adhesive strength and is a known technology, so description thereof will be omitted.

The nut 130 is integrally received in the panel-type holder 120 to form the nut hole 131. The nut 130, which is made of metal, is a foreign material different from the material of the panel-type holder 120 and must support the anchor 200, which has a relatively large self-weight, so a unique coupling structure is required between the nut 130 and the panel-type holder 120. This is required, and the shape of the nut 130 for this will be described in more detail below. In general, the nut 130 is a normal fastening member with threads formed on the inner surface, and the side of the nut 130 has a polygonal shape so that a wrench or spanner can be used. However, since the side of the nut 130 of the present invention has a polygonal shape, it expands the contact area with the panel-type holder 120 and contributes to integration with the panel-type holder 120, and the nut 130 is not attached to the panel-type holder (120) even by external force. 120) to maintain the same posture without self-rotation.

The panel-type holder 120 surrounds and accommodates the nut 130 so that the nut hole 131 is opened. That is, the panel-type holder 120 surrounds the nut 130 and is adsorbed to the outer surface, so that the body of the nut 130 is accommodated in the panel-type holder 120 without being exposed. Meanwhile, a plurality of panel-type holders 120 can be fixed at each designated position (Z) on the other side of the adhesive sheet 110, and the panel-type holder 120 is fixed to the adhesive sheet 110 through a fusion method. It is done firmly. Ultimately, the panel-type holders 120 and 120' (see FIG. 5) maintain their positions without being separated from the adhesive sheet 110 even under the load of the anchor 200 bolted to the nut 130. The panel-type holder 120 is made of an inflexible material that maintains its shape without bending. The anchor 200 is generally made of metal because it must have the strength to support the door (D) to maintain its current position. Therefore, if the holder 120 that supports the anchor 200, which has a relatively large self-weight, is easily bent, the installation of the anchor 200 may be unstable. Therefore, the holder 120 is made of an inflexible material and can be made of synthetic resin to enable molding to accommodate the nut 130 independent of the holder 120. In addition, it is desirable that the holder 120 is in close contact with the bracket 210 of the anchor 200 that is bolted to maintain its position without tilting or shaking. To this end, the holder 120 is connected to the panel. takes shape

The holder 120 has a specific shape to increase support strength, and a plurality of holders can be fixed to the adhesive sheet 110 in a specific arrangement, which will be described in more detail below.

The anchor 200 includes a bracket 210 that is in close contact with the holder 120 and bolted through a nut hole 131 (see FIG. 6), a leg 220 hinged to the bracket 210, and a bottom surface. It consists of a pad 230 mounted on the end of the leg 220 for friction. The bracket 210 is provided with a hole 213 through which the bolt B passes for bolting with the holder 120, and a pair of hinges 211 are protruded and formed parallel to each other.

The leg 220 supports the door (D) at its upper end, supports the floor at its lower end, and supports the door (D) to maintain its position. For this purpose, the upper end of the leg 220 is rotatably connected to the hinge 211 via the axle 212. Therefore, when the door (D) needs to be opened and closed, the user rotates the leg (220) so that the lower part of the leg (220) is upward to prevent the door (D) from getting caught, and the door (D) remains stopped at a specific position. If necessary, the user rotates the leg 220 so that the lower end of the leg 220 faces the floor so that the leg 220 supports the door (D).

The pad 230 is made of a material with a high friction coefficient and is mounted on the lower end of the leg 220 so as to be in contact with the floor. Therefore, the legs 220 maintain the current posture without slipping on the floor and support the door D to maintain its position.

Figure 6 is a perspective view showing a preferred embodiment of the nut sticker according to the present invention, Figure 7 is a cross-sectional view A-A' shown in Figure 5, and Figure 8 shows the force in a preferred embodiment of the nut sticker according to the present invention. This is a side view schematically showing the dynamics of the receiving holder.

Referring to Figures 4 to 7, the nut 130 is provided with a nut hole 131 formed with a protruding protrusion 133 along the edge of the inlet side, which passes through the side surface and has a polygonal shape, and the upper and lower surfaces have a nut hole ( 131) is formed at an angle. To describe the protruding protrusion 133 in more detail, the protruding protrusion 133 protrudes from the upper surface (F) or lower surface of the nut 130 along the inlet end of the nut hole 131 where the screw thread 132 is formed. Therefore, the nut hole 131 has a clear boundary between the upper surface (F) and the lower surface by the protruding protrusion 133. Meanwhile, the upper surface (F) and lower surface of the nut 130 are each tapered around the nut hole 131. Accordingly, the contact area between the upper surface (F) and the lower surface in contact with the holder 120 was expanded.

The panel-type holder 120 is adsorbed by surrounding the upper surface (F), lower surface, and side surface of the nut 130 so that the nut hole 131 is open based on the protruding protrusion 133, and accommodates the nut 130 in the center. It consists of a circular body 121 and an arm 122 that protrudes vertically from the center of the body 121 and has a width corresponding to the width of the nut 130. The holder 120, to which the anchor 200 is connected via the bolt B, can concentrate not only the self-weight of the anchor 200 but also the rotational force of the door D on the nut 130, so that the holder 120 can be connected to the nut 130 without bias. (130) must be supported stably on all sides. Therefore, it is desirable that the body 121 of the holder 120 in which the nut 130 is accommodated has a circular shape with the nut 130 placed at the center. Meanwhile, the body 121 surrounds the nut 130 and absorbs it to accommodate it. To prevent the nut 130 from leaving the body 121, the body 121 is attached to the upper and lower surfaces as well as the sides of the nut 130. It forms a structure that covers up to just before the protruding jaw (133). Ultimately, one side of the protruding protrusion 133 forms a section where the nut hole 131 is opened, and the other side forms a section covered by the body 121.

Meanwhile, the arm 122 of the holder 120 protrudes vertically straight from the center of the body 121. The arm 122 is intended to reinforce the support force of the body 121 with respect to the anchor 200 based on the center where the nut 130 is located, and resists the biased external force of the anchor 200 with respect to the holder 120 to support the holder. (120) supports external force to maintain a stable fixed state without being separated from the adhesive sheet (110). That is, when the anchor 200 applies downward force to the holder 120 through the bolt B, the inflexible holder 120, whose length is extended downward by the arm 122, is physically strengthened by the structure. It stores power and maintains the posture of the holder 120.

To explain this in more detail, as shown in FIG. 8, the bolt B receiving the weight of the anchor 200 transmits torque to the holder 120 through the nut 130. Therefore, the inflexible holder 120 attempts to rotate using the lowest point as the rotation point (CP1, CP2). However, when there is no arm 122, the first rotation point (CP1) of the holder 120 is the end of the body 121, whereas when the arm 122 is configured, the second rotation point (CP2) of the holder 120 ) is the end of the arm 122. Ultimately, since the second rotation point (CP2) is relatively far from the origin (P1) that receives the force, the arm 122 is a physical element that strengthens the resistance in response to the force applied from the bolt (B) according to the principle of the lever. .

Arm 122 has a width corresponding to the width of nut 130. That is, the width of the arm 122 is the same as or similar to the width of the nut 130. This is because the arm 122 along with the body 121 is adhered to the adhesive sheet 110 beyond the width of the nut 130 even when the nut 130 is shaken from side to side by the bolt B, resulting in a physically strengthened structure. This is to prevent the shaking.

Meanwhile, the holder 120 according to the present invention has an inclined side surface, so that the holder 120 can maintain a stable fixed state even when the bolt B is shaken by the anchor 200.

Figure 9 is a front view of a preferred embodiment of the nut sticker according to the present invention, and Figure 10 is a side view of Figure 9.

Referring to FIGS. 4 and 9 to 10, a plurality of holders 120a, 120b, and 120c accommodating the nut 130 are disposed on the adhesive sheet 110 in multiple rows of staggered horizontal bars, and the arms 122a, 122b, 122c) is directed toward the holders 120a, 120b, and 120c in the opposite row. In this embodiment, the holders 120a, 120b, and 120c form two rows, an upper row and a lower row, and the holders 120a in the upper row and the holders 120b, 120c in the lower row are arranged to be staggered. Accordingly, the holders 120a in the upper row have arms 122a disposed between the holders 120b and 120c in the lower row, and the holders 120b and 120c in the lower row have arms 122b and 122c on the left and right sides of the holders 120a in the upper row, respectively. This is placed.

Therefore, even if the leg 220 rotates upward and downward and external force is applied to the holders 120a, 120b, and 120c through the nut 130, the holders 120a and 120c are held by the arms 122a, 122b and 122c facing upward or downward. The fixing force of 120b, 120c) is strengthened, and the force applied to the adhesive sheet 110 can be distributed to maintain a stable fixation state.

Meanwhile, the holders 120a, 120b, and 120c accommodating the nuts 130 are arranged side by side with respect to the horizontal line L passing through the center of the adhesive sheet 110, and the arms of the holders 120a, 120b, and 120c (122a, 122b, 122c) intersect the horizontal line (L). That is, the upper and lower row holders 120a, 120b, and 120c are arranged side by side along the horizontal line (L). In this arranged state, the arms (122a, 122b, 122c) intersect the horizontal line (L), so the arm (122a) of the holder (120a) in the upper row protrudes between the positions of the holders (120b, 120c) in the lower row section, and The arms 122b and 122c of the holders 120b and 120c protrude to the left and right positions of the holder 120a in the upper row section.

Therefore, since the anchor 200, which applies a direct external force to the nut sticker 100, is connected to the center of the adhesive sheet 110, it does not receive the external force of the anchor 200 and is attached to the upper end of the adhesive sheet 110 attached to the door D. and the lower part can maintain a relatively stable adhesive state. In addition, the arms (122a, 122b, 122c) cover the horizontal line (L) passing through the center of the adhesive sheet (110), so that the holders (120a, 120b, 120c) are attached to the upper part of the adhesive sheet (110) with the horizontal line (L) as the center. Since it is fixed encompassing the lower part, the leg 220 of the anchor 200 rotates upward and downward repeatedly, and the adhesive sheet 110, which receives external force through the holders 120a, 120b, and 120c, moves along the horizontal line (L). Prevents folding problems.

For reference, the adhesive sheet ( 110) is preferably rectangular in shape where the vertical length is longer than the horizontal length. Therefore, the nut sticker 100 is firmly attached to the door (D) and can maintain a stable fixed state even when the leg 220 is repeatedly rotated up and down.

Although the detailed description of the present invention described above has been described with reference to preferred embodiments of the present invention, those skilled in the art or those skilled in the art will understand the spirit of the present invention as described in the patent claims to be described later. It will be understood that the present invention can be modified and changed in various ways without departing from the technical scope.
