Description

Technology Field

[0001] The present invention relates to a furniture panel used as a tabletop or a cabinet door, and more specifically, to a furniture panel in which a corner cushioning means is separately provided and formed on the corner portion of the furniture panel exposed to the human body, wherein the corner cushioning means is formed by dividing it into a fastening bracket directly fixed to the furniture panel and a cushioning member that is pressurized and fixed to the fastening bracket, so that multi-stage cushioning ribs absorb the impact in response to the magnitude of the impact acting on the corner of the furniture panel through the cushioning member according to the intensity of the impact, thereby minimizing injury or pain, while simultaneously allowing the corner cushioning means to be quickly and simply installed on the corner portion of the furniture panel. Background Technology

[0002] Generally, study tables, lecture tables, conference and work tables, etc., are equipped with a flat, rectangular tabletop made of wood, synthetic resin, or metal. In addition, various storage cabinets, etc., have doors that can be opened and closed, with one side hinged to each partitioned space; such doors are also made by bending and forming wood, synthetic resin, or metal.

[0003] Furniture panels, such as table tops or cabinet doors, have a flat, rectangular shape with a certain thickness, and due to this rectangular form, right-angled corners are formed on all four sides. Consequently, if these right-angled corners interfere with or collide with the human body while using furniture such as tables or cabinets, they can potentially cause serious injuries as well as severe pain. As such, there is a growing trend to apply various protective measures to the corners of furniture panels, which are considered defects harmful to the human body.

[0004] In other words, typically, the corners of furniture panels are processed into rounded shapes to reduce injury or pain upon contact or collision. However, due to the rounded shape, in the case of cabinets, there is a problem where an unnecessarily excessive gap or gap occurs between the storage space of the furniture body and the door edge, and in the case of tables, the usable area is reduced by the amount of the rounded processing area, resulting in the disadvantage of having to set and manufacture the size of the tabletop excessively.

[0005] In addition, to prevent this, users purchase and directly attach corner protectors made of soft elastic material to each corner of square furniture panels, thereby reducing injury or pain. However, since the corner protectors attached to right-angled corners are also manufactured in a right-angled shape, they cannot achieve an effect beyond the cushioning properties of the material itself. Furthermore, the double-sided tape used to attach the corner protectors to the furniture panels easily separates or detaches over time or due to strong physical impact, resulting in a problem where a stable attachment state cannot be continuously maintained.

[0006] In recent years, furniture panels equipped with a corner protection function have been registered, such as Registered Patent No. 10-2670014 and Registered Patent No. 10-2670021, in which a collision shock mitigation part is placed in an installation space formed at each corner of the panel body to mitigate the impact caused by external collisions, thereby preventing safety accidents caused by hitting the corners and improving safety of use.

[0007] In addition, there is a registered furniture panel equipped with a corner protection function that improves safety of use by preventing injury caused by collision of corners, such as in Registered Patent No. 10-2676288, in which a shock-absorbing corner portion is forcibly inserted into an insertion groove of a chamfered portion of the panel body to form a corner that mitigates impact caused by collision. The disclosed furniture panel equipped with a corner protection function comprises a panel body in which each corner is chamfered and an insertion groove is formed in the chamfered portion, and a shock-absorbing corner portion that is forcibly inserted into the insertion groove to form a corner that mitigates impact caused by collision in the chamfered portion of the panel body.

[0008] Furthermore, in the case of Registered Patent No. 10-2759568, a furniture panel equipped with a corner protection function is registered, wherein a corner forming member is supported elastically by a mounting cover while positioned in the installation space of the panel body by an elastic tilting connection part, thereby preventing safety accidents caused by hitting the corner and improving safety of use. It is known that having a structure in which the corner forming member is supported elastically by a mounting cover while positioned in the installation space of the panel body by an elastic tilting connection part has the effect of preventing safety accidents caused by hitting the corner and improving safety of use.

[0009] However, existing corner safety members or corner cushioning structures, including the aforementioned prior examples, are composed of complex structures and components that excessively increase the economic value and cost of these furniture panels, making them extremely uneconomical. Furthermore, since most of them consist of fluids made of synthetic resin that are deflected by springs or elastic bands, they fail to provide organic cushioning depending on the direction or intensity of the impact. This makes them inefficient and carries the drawback of potentially causing more serious injuries or pain than wooden furniture panels, depending on the direction or angle of impact.

[0010] In addition, protective members made of soft elastic materials have a significant problem in that their adhesive fixation with furniture panels is significantly reduced, leading to frequent instances where they easily separate from or are torn and damaged. Furthermore, since they are manufactured with a limited level of elasticity utilizing only the characteristics of the material, they may become excessively soft in some cases and fail to respond to strong impacts, or if they are made of a relatively hard material to prepare for large impacts, they fail to perform an effective shock absorption function for small impacts such as light bumps. Consequently, the problem of significantly reduced responsiveness to impact intensity is consistently being pointed out. Prior art literature

[0012] The present invention improves upon the aforementioned problems by forming a cut surface portion by chamfering at a 45° angle on a right-angled panel corner and attaching a separately provided corner cushioning means to the chamfered cut portion, wherein the corner cushioning means is formed by dividing it into a fastening bracket fixed to the bottom corner surface of the panel where the cut portion is formed and a cushioning member made of a soft elastic material that is pressurized and fixed to the fastening bracket.

[0013] The objective of the present invention is to provide a furniture panel combined with a multi-stage ribbed corner cushioning means, which is characterized by increasing the efficiency of corner processing of the panel and the productivity of the corner cushioning means, while simultaneously improving interassembly capabilities. Furthermore, the corner cushioning means, which is easily attached to the furniture panel, produces a more efficient and reasonable cushioning effect depending on various directions and impact intensities, thereby providing excellent cushioning action for panel corners that cause injury or severe pain to the human body due to collisions during the use of furniture having panels such as tops or doors. means of solving the problem

[0014] The present invention, for achieving the above-mentioned purpose, comprises a corner cushioning means having a separate component formed by a 45° angled cut surface portion at a right-angled corner portion of a furniture panel, a fastening bracket fixed to the bottom surface of the panel in the direction in which the chamfer is formed, and a cushioning member made of a triangular soft elastic material that is press-fixed to the fastening bracket and has one side facing the cut surface portion.

[0015] The above-described fastening bracket is configured such that a pair of dovetail fitting holes protrude upward on one side of the upper portion and a pair of fastening holes are formed through the fastening bracket. The above-described buffer member is configured such that a contact surface is formed on one side in contact with the cut surface of the panel, and an upward buffering groove is formed on the lower portion. An inner flat surface is formed on one side of the buffering groove in a direction corresponding to the contact surface, and a dovetail fitting groove corresponding to the dovetail fitting holes of the fastening bracket is formed on the inner flat surface. Furthermore, a plurality of buffering ribs protruding toward the inner flat surface are formed on the entire inner surface of the buffering groove, excluding the inner flat surface. The ends of the buffering ribs are configured such that the buffering ribs extending from the outer side toward the center of the buffer member are gradually spaced apart from the inner flat surface. Effects of the invention

[0016] The present invention simply involves chamfering the corners of a furniture panel to easily attach a cushioning member, thereby increasing processing efficiency for the panel corners and enhancing assembly with the cushioning member. Furthermore, since a cushioning member made of a soft elastic material can be simply press-fastened to a fastening bracket that is firmly fixed to the panel, the attachment and fixing of the corner cushioning means is very concise and simple, as well as offering excellent productivity, assembly, and stability of use. Additionally, the corner cushioning means attached to the panel corners produces superior cushioning action through multi-stage cushioning ribs of varying lengths that provide organic response depending on the direction or intensity of impact, contributing to the prevention of human injury and reduction of pain, while its excellent shape recovery ability significantly extends its service life.

In describing the present invention, if it is determined that a detailed description of related prior art could unnecessarily obscure the essence of the present invention, such detailed description is omitted.

[0024] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0025] FIG. 1 is an enlarged perspective view of a corner portion of a furniture panel of the present invention, FIG. 2 is an overall separated perspective view of a corner portion of a furniture panel of the present invention, a fastening bracket, and a cushioning member, FIG. 3 is a perspective view of a state in which only the cushioning member is separated from a corner portion of a furniture panel of the present invention, FIG. 4 is a separated perspective view of a corner portion of a furniture panel of the present invention in another direction, FIG. 5 is an enlarged bottom view of a corner portion of a furniture panel of the present invention, FIG. 6 is a combined cross-sectional view of a corner portion of a furniture panel of the present invention and a cushioning means, FIG. 7 is a separated cross-sectional view of a corner portion of a furniture panel of the present invention and a cushioning means.

[0026] As shown in the example, the furniture panel of the present invention is made by forming a cut surface (101) by chamfering at a 45° angle on a right-angled corner portion of a furniture panel (100) used as a table top or a door of a storage cabinet, and forming a triangular corner cushioning means (200) made of a soft elastic material, such as silicone or rubber, on the chamfered portion of the panel (100). The corner cushioning means (200), which has a shape corresponding to the 45° chamfer and the chamfered portion, can perform a stable cushioning action against the impact of the human body acting on the corner portion of the furniture panel in almost all directions, regardless of the direction of impact.

[0027] At this time, the work location and number of units for the chamfering cutting process for the panel (100) and the joining process of the corner cushioning means (200) can be changed according to the purpose of use of the panel (100). In the case of the panel (100) used as a square table top, the chamfering work and the joining of the corner cushioning means (200) will be performed on the four corner parts on all sides or on two parts on one side facing the user. In the case of the panel (100) used as an opening and closing door for a storage cabinet, the chamfering work and the joining of the corner cushioning means (200) will be performed on the upper and lower ends opposite the hinge joint. The work process and the joining of the corner cushioning means (200) can be freely adjusted according to the characteristics, purpose, location, and direction of the object to which the furniture panel (100) is to be used.

[0028] Thus, the panel of the present invention is completed by forming a cut surface portion (101) by chamfering at a 45° angle in a right-angled corner portion of a furniture panel (100), and by providing a corner cushioning means (200) separately provided, which consists of a fastening bracket (210) fixed to the bottom surface of the panel (100) in the direction in which the chamfer is formed, and a cushioning member (220) made of a triangular soft elastic material that is pressed and fixed to the fastening bracket (210) and has one side facing the cut surface portion (101), and by fixing the corner cushioning means (200) in close contact with the chamfered cut surface portion (101) of the furniture panel (100).

[0029] Here, the fastening bracket (210) of the corner cushioning means (200) is made by injection molding synthetic resin, and is configured such that a pair of dovetail fitting holes (211) (211') protrude upward on one side of the upper part, and a pair of fastening holes (212) (212') are formed through the fastening bracket (210), thereby serving as a medium for firmly attaching and fixing the cushioning member (220) to the panel (100).

[0030] Furthermore, the above buffer member (220) is configured such that a contact surface (221) is formed on one side in contact with the cut surface (101) of the panel (100), and an upward buffer groove (222) is formed on the lower side, and an inner flat surface (223) is formed on one side of the inner side of the buffer groove (222) in a direction corresponding to the contact surface (101), and a dovetail fitting groove (224) (224') corresponding to the dovetail fitting hole (211) (211') of the fastening bracket (210) is formed on the inner flat surface (223), and a plurality of buffer ribs (225) (225') protruding toward the inner flat surface (223) are formed on the entire inner surface of the buffer groove (222) excluding the inner flat surface (223), and the end portions of the buffer ribs (225) (225') are of the buffer member (220). The buffer ribs (225) (225') extending from the outer side toward the center are configured to be gradually spaced apart from the inner flat surface (223).

[0031] Accordingly, with the upper surface of the fastening bracket (210) in close contact with the lower surface of the corner portion of the furniture panel (100), a separately provided fastening bolt (notation in the drawing is omitted) is inserted into the fastening hole (212) (212') formed in the fastening bracket (210) and tightened so that the fastening bolt is firmly screw-fixed to the lower surface of the panel (100), thereby creating a firmly fixed state of the fastening bracket (210) to the panel (100), and the dovetail-shaped fitting hole (211) (211') of the fastening bracket (210) is spaced apart with a predetermined distance in front of the cut surface portion (101) of the panel (100).

[0032] Accordingly, when downward pressure is applied so that the fitting member (211)(211') of the fastening bracket (210) is inserted tightly into the dovetail-shaped fitting groove (224)(224') formed inside the cushioning groove (222) of the cushioning member (220) while holding the cushioning member (220) of the corner cushioning means (200), the cushioning member (220) is firmly assembled to the fastening bracket (210) due to the combination of the mutually corresponding fitting grooves (224)(224') and the fitting member (211)(211') in the dovetail shape. At the same time, the contact surface (221) of the cushioning member (220) is in close contact with the cut surface (101) of the panel (100), thereby completing the connection and assembly in a tight state without any gaps between them.

[0033] In addition, the dovetail-shaped fitting member (211)(211') and fitting groove (224)(224') will not only further enhance the coupling and fixing force of the cushioning member (220) of the soft elastic material to the fastening bracket (210), but will also serve to prevent the cushioning member (220) from separating, detaching, or moving from the fastening bracket (210) even when an impact is applied to the cushioning member (220).

[0034] Thus, when an impact occurs due to a collision with a human body or an object on the corner portion, such as a table top or a storage box door, applied to the furniture panel (100) of the present invention, the cushioning member (220) undergoes elastic indentation and compressive deformation inward due to the impact. During this indentation process, the plurality of cushioning ribs (225) (225') formed within the cushioning groove (222) inside the cushioning member (220) sequentially interfere with the inner flat surface (223) within the cushioning groove (222) according to the impact intensity, thereby producing a stepwise cushioning effect.

[0035] In other words, unlike conventional methods that rely on the elastic force of the cushioning material itself regardless of impact intensity or rely on the simple mechanical cushioning action of the cushioning material, the inner ends of the cushioning ribs (225) (225'), each having different lengths depending on the magnitude of the impact acting on the cushioning member (220), will sequentially interfere with the inner flat surface (223) on one side of the inner surface of the cushioning groove (222) of the cushioning member (220), thereby producing a gradual resistance force. In the case of a small impact, the end of the cushioning rib (225) (225'), which has the shortest length, will first interfere with the inner flat surface (223), thereby producing a predetermined reaction force and cushioning effect. In the case of a large impact, the end of the cushioning rib (225) (225'), which has a progressively longer length, will sequentially come into contact with the inner flat surface (223), thereby producing a gradually increasing reaction force. Consequently, depending on the magnitude of the impact, the ribs of different lengths The cushioning ribs (225) (225') respond organically to mitigate and absorb shock, thereby producing excellent cushioning performance that is incomparable to conventional cushioning means, and as a result, injuries or pain can be significantly reduced.

[0036] In particular, a mounting groove (102) with a depth equal to the thickness of the fastening bracket (210) of the corner cushioning means (200) is formed on the bottom surface of the furniture panel (100), so that the fastening bracket (210), which is fixed in close contact with the bottom surface of the panel (100), can be fixed in a state where it is inserted into the mounting groove (102), thereby allowing the bottom surface of the fastening bracket (210) to be fixed in a state where it does not protrude from the bottom surface of the panel (100). Additionally, a retaining groove (226) with a depth equal to the thickness of the fastening bracket (210) is formed on one side of the bottom surface of the cushioning member (220) of the corner cushioning means (200), so that the upper part of the fastening bracket (210) can be inserted into the retaining groove (226) and they can be mutually coupled, so that the bottom surface of the panel (100), the bottom surface of the fastening bracket (210), and the bottom surface of the cushioning member (220) all maintain the same flat plane and have a smoother back surface or bottom surface. The panel (100) can be completed.

[0037] In addition, as shown in FIGS. 8 and 9, a transverse cut groove (227) may be formed on the upper side of the cushioning member (220) of the corner cushioning means (200) so that an upper and lower penetrating cushioning groove (222) may be formed on the lower side of the cut groove (227). When an impact is applied from the side of the cushioning member (220), the cushioning effect caused by compression in the direction of the cushioning groove (222) is further enhanced by the upper and lower penetrating cushioning groove (222) and the internal cushioning ribs (225) (225') due to the cut groove (227), thereby producing smoother bending and cushioning. Furthermore, when an impact is applied from the surface direction of the cushioning member (220), a cushioning space equal to the gap created by the cut groove (227) is added, so a more gradual cushioning effect can be expected even against impacts from the surface direction.

[0038] Accordingly, the panel (100) having the corner cushioning means (200) of the present invention may be used as a table top equipped with a lower frame body having a vertical column-shaped support angle as shown in FIG. 10, or as a table top equipped with lower support bodies spaced apart from each other as shown in FIG. 11, and if necessary, may be used as an opening and closing door for various lockers or storage boxes as shown in FIG. 12.

[0039] In addition, it can be used as a panel for various types of kitchens, living rooms, or living room furniture, and can prevent or significantly reduce pain or injury upon contact with the human body without compromising the aesthetic appearance of the furniture.

[0040] Furthermore, when the panel (100) having the corner cushioning means (200) of the present invention is used as a tabletop or a door for opening and closing a storage box, the exposed front surface of the corner cushioning means (200) has a smooth shape so as not to impair the appearance or aesthetics of the furniture at all, and through the cushioning groove (222) formed on the back surface of the cushioning hole (220) of the corner cushioning means (200) and the plurality of cushioning ribs (225) (225') of different lengths, it exhibits a more perfect and efficient cushioning action, thereby enabling it to perform the role of an even more ideal cushioning means.

[0041] As such, the furniture panel of the present invention has excellent assembly productivity because a corner cushioning means (200) made of a soft elastic material can be simply attached to the corner in the required direction. The corner cushioning means (200) has excellent effects in significantly reducing physical impact caused by collisions with the human body or objects acting in various directions and sizes, by reducing the impact size or stages, thereby significantly reducing injury or pain to the human body or damage to objects. Furthermore, it is more rational because it can be naturally attached without compromising the external aesthetics or design characteristics of the furniture panel (100) itself.

[0042] The embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; therefore, it should be understood that there may be various equivalents and modifications that can replace them.
