Description

Technical Field

[0001] The present invention relates to an adhesive door stopper installation system. More specifically, the structure is improved such that a fixing bracket and a spacer are temporarily assembled by fitting an elastic piece into a square hole, enabling anyone to easily install the door stopper in a fixed position. In particular, a buffer pad locally contacts the edge of the fixing bracket by the spacer, and the present invention relates to an adhesive door stopper installation system that can flexibly absorb the repeated impact loads generated during the folding operation of the door stopper.

Background Art

[0002] Generally, a door stopper is installed at the lower end of the inner surface of a door to support the door in an open state and prevent the door from closing. It has a base fixed to the lower end of the door with screws, and a support bar is installed, which is hinged (hinged) to a bracket integrally formed on the base and is rotatable. A pad made of a rubber material is installed at the end of the support bar to be in contact with and supported on the bottom surface.

[0003] However, when holding the door in an open state, the load in the door closing direction transmitted through the support bar concentrates on the base and the screws fixing the door, resulting in the screws falling off or play occurring in the base, and the function of the door stopper being lost in reality.

[0004] Therefore, in Patent Document 1 disclosed in the prior art, an engaging plate forming an engaging surface that abuts against a door, a pair of recesses formed on the left and right sides of the inner surface of the engaging surface formed on the engaging plate, and formed inside the pair of recesses, and is formed in an elongated hole shape extending in the up and down directions so that a bolt can be coupled. One of the positions in the up and down directions is formed to have the same size as the diameter of the bolt, and the other position is formed larger than the diameter of the bolt as it extends. A coupling means forming adjustment grooves at the first and second positions, a coupling bracket coupled to the coupling means by a bolt, a support base rotatably coupled to the coupling bracket, and a pad support portion formed on the lower side of the support base have been proposed.

[0005] However, the prior art is for improving the adhesion between the lower surface of the pad support portion and the bottom surface when elastically biasing the pad support portion when using a door stopper, and for reducing noise and preventing damage when a collision occurs between the coupling bracket and the pedal when operating the door stopper. However, the structure is complex, and the manufacturing cost increases due to the diversification of parts, so there is no price competitiveness. In addition, since the engaging plate must be fastened to the door with screws, there is a problem that the door is damaged, and moreover, in a general household without a dedicated tool including a drill, no one can easily install it.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] FIG. 1 is a perspective view showing an adhesive door stopper installation system according to an embodiment of the present invention as a whole, FIG. 2 is a configuration diagram showing an adhesive plate of the adhesive door stopper installation system according to an embodiment of the present invention, and FIGS. 3 and 4 are configuration diagrams showing a temporary assembly module of the adhesive door stopper installation system according to an embodiment of the present invention, and FIGS. 5 and 6 are configuration diagrams showing a set member of the adhesive door stopper installation system according to an embodiment of the present invention.

[0020] The present invention relates to an adhesive door stopper installation system for installing a door stopper 1 that supports the door open state by a support bar 1b that is pivotally connected to a fixed bracket 1a and pivots, in a boltless manner (without bolts) on the door. At this time, the structure of the adhesive door stopper installation system is improved so that the fixed bracket and the spacer are temporarily assembled by fitting an elastic piece and a square hole, and anyone can easily install the door stopper in a fixed position. In particular, the adhesive plate 10, the spacer 20, the inner buffer chamber 30, the fastening tube 40, the temporary assembly module 50, and the buffer pad 60 are mainly configured to be able to flexibly absorb the repeated impact loads generated during the folding operation of the door stopper by the buffer pad locally contacting the edge of the fixed bracket by the spacer.

[0021] The adhesive plate 10 according to the present invention has an adhesive surface 12 formed on one surface so as to be attached to the door.

[0022] The adhesive plate 10 is made of a synthetic resin material and can be mass-produced by injection molding.

[0023] An adhesive tape is attached to one surface of the adhesive plate 10. The adhesive tape is finished with a release paper. When installed on-site, the adhesive surface 12 is exposed by removing the release paper.

[0024] Also, the spacing fixture 20 according to the present invention is formed to project on the other surface of the adhesive plate 10 to locally support the edge area of the fixing bracket 1a and is provided to support with a space between the adhesive plate 10 and the fixing bracket 1a.

[0025] As shown in FIG. 1, the spacing fixture 20 is formed in the same shape as the outer shape of the fixing bracket 1a of the door stopper 1.

[0026] Then, the spacing fixture 20 separates the adhesive plate 10 and the fixing bracket 1a, and a fastening tube 40 described later projects by the separated distance, securing a fastening space for the bolt 42.

[0027] Also, the inner baffle chamber 30 according to the present invention forms a separation partition between the adhesive plate 10 and the fixing bracket 1a by the spacing fixture 20.

[0028] The inner baffle chamber 30 is a space where the adhesive plate 10 and the fixing bracket 1a are separated in a non-contact state. Together with the spacing fixture 20, it forms a separated section and provides a space that can buffer the impact applied from the door stopper 1 together with a buffer pad 60 described later.

[0029] That is, the inner baffle chamber 30 is provided so that the edge area of the fixing bracket 1a locally contacts the spacing fixture 20 to locally pressurize the buffer pad 60, thereby improving the buffering efficiency.

[0030] In addition, the fastening pipe 40 according to the present invention is provided so as to project from the adhesive plate 10 corresponding to the inner baffle chamber 30 and be screwed with a bolt 42 inserted through the mounting hole H of the fixing bracket 1a.

[0031] The fastening pipe 40 is disposed at a position corresponding to the mounting hole H of the fixing bracket 1a and is formed of a hollow pipe body. While the bolt 42 enters, it is fastened while forming a female screw portion.

[0032] In addition, a temporary assembly module 50 according to the present invention is provided to fasten the adhesive plate 10 and the fixing bracket 1a in a fitting manner.

[0033] The temporary assembly module 50 includes a square hole 52 formed in the fixing bracket 1a and a pair of elastic pieces 54 that project from the adhesive plate 10 corresponding to the square hole 52 and are fitted to both side surfaces of the square hole 52.

[0034] At this time, the width of the pair of elastic pieces 54 is formed to be larger than the width of the square hole 52 so that the elastic pieces 54 are elastically deformed and fitted into the square hole 52 during fitting.

[0035] In this way, by fitting the elastic piece 54 and the square hole 52, the fixing bracket 1a is temporarily assembled to coincide with the spacer 20, and there is an advantage that anyone can easily install the door stopper 1 in a fixed position.

[0036] At this time, the elastic piece 54 is arranged in the vertical direction, is formed to be smaller than the vertical width of the square hole 52, and a locking piece 56 projects in the vertical direction at the upper end portion.

[0037] As a result, as shown in FIG. 3, when the fixing bracket 1a is moved downward with the elastic piece 54 fitted into the square hole 52, the locking piece 56 is provided so as to be locked and coupled to the back surface of the fixing bracket 1a, thereby reinforcing the fastening force between the fixing bracket 1a and the adhesive plate 10. Even when a high load acts on the door stopper 1, loosening and dropping of the fixing bracket 1a are prevented.

[0038] In FIG. 4, the elastic pieces 54 are arranged in the vertical direction, and a locking piece 57 is provided in the horizontal direction between the elastic pieces 54.

[0039] The locking piece 57 is inserted into the square hole 52 and provided so as to be locked and coupled to the back surface of the fixing bracket 1a. Thus, the fixing bracket 1a and the adhesive plate 10 are locked and coupled by the locking piece 57 in the state where they are temporarily assembled by the temporary assembly module 50, and the position is fixed.

[0040] As a result, loosening of the fixing bracket 1a is prevented while the door stopper 1 is installed on the door, and there is an advantage that anyone can easily perform construction at a fixed position.

[0041] Further, the buffer pad 60 according to the present invention is provided on one surface of the fixing bracket 1a and is provided so as to be grounded to the space holder 20 and the fastening pipe 40.

[0042] The buffer pad 60 is made of a rubber material and is formed in the same shape as the fixing bracket 1a.

[0043] Furthermore, the buffer pad 60 is disposed between the fixing bracket 1a and the space holder 20, and can effectively prevent loosening of the bolt 42 by flexibly absorbing the repeated impact load generated during the folding operation of the door stopper 1.

[0044] In FIG. 2, the interior of the inner baffle chamber 30 is partitioned into a plurality of spaces by a baffle plate 32, and the baffle plate 32 is provided so as to connect the spacer 20 and the fastening pipe 40.

[0045] The spacer 20 and the fastening pipe 40 are mutually reinforced by the baffle plate 32, improving durability, and the buffer pad 60 has its bearing area expanded by the baffle plate 32, improving the efficiency of shock absorption associated with the folding operation of the door stopper 1.

[0046] Further, the adhesive plate 10 is made of a polycarbonate material, and a positioning groove 14 is formed in the adhesive plate 10 corresponding to the inner baffle chamber 30.

[0047] The positioning groove 14 is formed at a depth of 80 to 95% based on the thickness of the adhesive plate 10 and is provided to guide the screw fastening position.

[0048] That is, when the adhesive force of the adhesive surface 12 of the adhesive plate 10 is not strong, the positioning groove 14 is provided so that the screw can be further tightened to reinforce the binding force.

[0049] In FIG. 5, the adhesive plate 10 is provided so that the position to be attached to the door is determined by the set member 70.

[0050] The set member 70 includes a support piece 71 with one end connected to the adhesive plate 10 and the other end grounded to the bottom surface G corresponding to the door opening and closing radius, and a cutting line 72 formed by a concave groove at the boundary where the adhesive plate 10 and the support piece 71 are connected.

[0051] At this time, it is preferable that the support piece 71 is integrally injection-molded with the adhesive plate 10.

[0052] To explain the usage state, after attaching the adhesive surface 12 to the door in a state where the height of the adhesive plate 10 is adjusted so that the support piece 71 is grounded on the bottom surface G, the support piece 71 is provided so as to be bent and removed with the cutting line 72 as a boundary.

[0053] In this way, by accurately maintaining the installation height and horizontal level of the adhesive plate 10 by the support piece 71, convenience is provided that allows anyone at home to easily install it themselves.

[0054] In FIG. 6, the adhesive plate 10 is provided so that the position to be attached to the door is determined by the set member 70.

[0055] The set member 70 includes a release paper 75 that adheres to protect the adhesive surface 12, and a breaking line 76 that is formed horizontally at a position 3 to 10 mm upward from the lower end of the release paper 75.

[0056] The release paper 75 is divided into upper and lower sheets 75a and 75b with the breaking line 76 as a boundary, and is provided so that the upper sheet 75a is partially removed from the adhesive surface 12 and folded downward with the breaking line 76 as a boundary.

[0057] Here, the breaking line 76 is configured to repeatedly arrange cutting portions and connecting portions at regular intervals so that the upper sheet 75a of the release paper 75 can be accurately folded.

[0058] To explain the usage state, as shown in FIG. 5(a), after removing the upper sheet 75a of the release paper 75 from the adhesive surface 12, it is bent 180° downward with the breaking line 76 as a boundary. As shown in FIG. 5(b), with the lower end of the upper sheet 75a grounded on the bottom surface G corresponding to the door opening and closing radius, the adhesive surface 12 is attached to the door in a state where the height of the adhesive plate 10 is adjusted, and the upper area of the release paper is pulled downward to remove the lower area of the release paper from the adhesive surface.

[0059] In this way, by using the release paper 75 to accurately maintain the installation height and horizontality of the adhesive plate 10, convenience that allows anyone at home to easily install it by themselves is provided.
