Description

{The shelf connecting apparatus for the enclosing furniture}

The present invention is intended to simply and easily install a shelf from the inside of storage furniture, and in detail, it is an organic connection between functional fastening members fastened to the outer circumference of a plate-type shelf and fastening grooves provided in the side panel of the storage furniture main body. This ensures that the shelf at the mounting location does not move due to physical external forces such as shock, shaking, or earthquake and generates a firm fixing force. In addition, anyone of any age or gender can easily attach and detach the shelf, further improving ease of use and quality stability. This relates to shelf fastening members for storage furniture as much as possible.

In general, shelf-type storage furniture (bookcases, cupboards, display cases, cabinets, lockers, wardrobes, bathroom cabinets, shoe racks, bookshelves, etc.) is equipped with at least one shelf to efficiently partition and utilize the available space inside the furniture body. It is used for storing and displaying various items such as books, dishes, and decorations, and is processed and produced into various forms using laminated wood boards (PB, MDF).

Representative prior documents for the above shelf-type storage furniture include Korea Public Utility Model No. 1996-0026595 and Korea Public Utility Model No. 1996-0019842, and these storage furniture have the back, both sides, and the top and bottom. The sides are connected with panels to form the main body, and fixing grooves are machined on the inner peripheral surface of the panels on both opposing sides, then cylindrical shelf holder pins (dowels) are installed, and then a plate-shaped shelf is placed on top of them to store various items. This was done so that the display could be done. Although this type of conventional storage furniture has a structure suitable for performing its original role, the shelf is simply placed on the upper side of the dowel and is in direct contact, so it is difficult to secure the stability of the shelf installation from physical external forces such as shaking, shock, or vibration caused by an earthquake. It contains difficult structural problems.

For example, shelf holder pins (dowels) do not hold the shelf so that it does not move in the up and down directions as well as the front and back directions, but are simply supported from below. They are usually cylindrical or cylindrical in shape, and the contact area with the shelf is not sufficient, so the shelf is not supported. It is bound to be unstable, so if the center of gravity is shifted toward the front end of the shelf or the storage furniture is tilted, it is difficult to prevent the shelf from moving or moving forward, and there is a risk of damage and safety accidents due to the tipping and falling of the loaded items and the shelf itself. , As the frequency of earthquakes in Korea is increasing recently, when an earthquake occurs, vertical vibrations (up and down vibrations) transmitted to storage furniture can cause economic losses such as shelves shaking and items being swept away or falling to the floor and being damaged. will be. In addition, when changing the installation location or moving the storage furniture, the shelf in an unstable position must inevitably be removed and reinstalled, which increases the inconvenience in use, and the insertion support between the fixing groove and the dowel fastening part is weak, so it cannot be fixed from the continuously applied load. In addition to the structural limitations that it is difficult to avoid deformation and clearance of grooves or dowels and thus difficult to secure shelf installation stability, there is a problem that acts as a factor in shortening the service life of shelf-type storage furniture.

(Prior document 0001) Korea Open Utility Model No. 1996-0026595 (published on August 17, 1996) (Prior document 0002) Korea Public Utility Model No. 1996-0019842 (published on July 18, 1996)

First, the fixture 20 and the coil spring 30 are installed by inserting them into the housing groove 12, and the fixture lever 22 is inserted into the movable slit hole 14 on the bottom of the housing. The fixture 20 is placed in the groove 12, and then the coil spring 30 is inserted into the resting groove 12 on the opposite side of the fixture sliding movement direction so that the fixture 20 is raised and lowered in a tension state. In addition, as the pin guider 40 is pressurized and fastened to the upper side of the open mounting groove 12 in a suppressed fit manner, separation or movement of the fixture 20 and the coil spring 30 are suppressed in a solid support state, and the high In a state where the fixing pin (21) on one side is located in the entrance/exit hole (43a) of the locking shoulder (43) of the pin guider, it is inserted into the entrance/exit hole (43a) according to the elastic tension action of the coil spring (30) on one side, protrudes outward, and The stopper 23 on the other side of the stopper 20 is caught on the pin guider locking shoulder 43 to control the protruding length of the fixing pin 21.

In this way, with the fixture 20, the coil spring 30, and the pin guider 40 organically fastened within the housing 10, the housing 10 is pressed and fastened into the shelf groove 2a to form a fastening member. When the installation of (A) is completed, the housing insertion state can be accurately recognized from the step-type flange portion 11 on the lower side of the housing 10, and the ratchet-type anti-removal protrusion 13 protruding along the circumference of the housing is grooved ( 2a) The housing 10 is firmly pressurized and fastened without being separated from the installation position by engaging in a wedge shape on the inner circumferential surface. If necessary, a separate fixing means such as a screw 50 is installed through the fastening hole 16 of the housing. ) and then fastening it to the shelf (2) so that the fastening member (A) can be more strongly mounted and fixed to the shelf.

The shelf (2) equipped with the fastening member as described above is installed inside the storage furniture in connection with the fastening grooves (1a) (1a') of the side panel, and is first inserted into the storage furniture with the shelf (2) tilted at an angle. After adjusting the balance in the horizontal direction, the fixing pin (21) is pressed against one surface (inner peripheral surface) of the opposing side panel (1) (1'), compressing the coil spring (30), and is installed in this state. When the shelf (2) is moved in all directions to the desired height and positioned so that the fixing pin (21) is inserted into the corresponding fastening groove (1a) (1a') of the side panel, the elastic tension force of the coil spring (30) The fixing pins 21 are inserted into the fastening grooves 1a and 1a' in a solid state as shown in FIG. 4, so that the installation of the shelf 2 can be completed easily.

While compressing (30), the fixing pin 21, which was inserted and fixed into the fastening groove 1a (1a'), moves together and is separated and moved, and after the fixing pin is separated in this way, it is moved at the middle position of the movable slit hole 14. The fixture lever (22) is inserted and fixed into the inside of one of the pair of stop slit holes (15) formed in the shelf (2) so that the fixing pin (21) is stopped without moving at the separation position. When the fixation on one side is released and the shelf (2) is tilted diagonally while lightly lifting or lowering it in the upper or lower direction, the fixing pins (21) of the fastening members on the opposite side are connected to the fastening grooves (1a) (1a'). It is naturally withdrawn from the shelf, making it possible to easily and easily separate the entire shelf (2). In addition, as all of the fixing members 20 mounted on the four shelves are moved toward the inside of the shelf and fixed within the stop slit holes 15, the fixing pins 21 protrude outward when moving and storing the shelf 2. This fundamentally prevents damage or deformation of the fixing pin 21 due to contact and interference with surrounding items, thereby further improving user convenience and storage.

The shelf fastening member reflecting the earthquake-resistant design having such a configuration and embodiment can be said to be a new useful invention with improved installation, ease of use, and stability, and is very useful as a means of fixing shelves for efficiently storing and displaying various items.
