Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shelf, and more particularly to a shelf comprising a pair of side frames and a receiving shelf suspended horizontally between the side frames.

BACKGROUND ART Conventional shelves for accommodating various instruments and the like generally consist of a highly rigid frame surrounding the four peripheries and a removably horizontally suspended shelf between the side walls of the frame. However, such a shelf has problems in that the frame is quite heavy, expensive, and inconvenient to handle. On the other hand, this problem can be solved by simply installing and removably mounting the receiving shelf horizontally between a pair of side frames, but there is a problem in terms of strength, particularly in that the rigidity against lateral vibration in the direction in which the side frames are arranged is weak. Not only that, but if the shelf moves unexpectedly or an unexpected lifting force is applied from below, the other side will tilt up using one of the locking parts as a fulcrum, causing the items placed on the shelf to lift up. There was a risk of falling or falling.

In view of these problems, the present invention aims to provide a shelf that is composed of a pair of side frames and a removable receiving shelf, and that has sufficient joint strength and rigidity.

For this reason, the present invention provides a side frame with horizontal bars installed at appropriate intervals vertically between a pair of supports, and arranges the side frames facing each other with a pair of spacing between them. an inverted U-shaped fitting portion that fits into the horizontal beam from above; and an engaging protrusion that protrudes from the fitting portion so as to engage with a side surface of the support column that faces the side frame arrangement direction; To provide a shelf which is firmly fixed by fitting the fitting part to the horizontal beam and has increased rigidity against lateral vibration by the engagement of the engaging protrusion with the side surface of the column.

The side frame and the shelf can all be constructed of wire rods. In that case, if the side frame is constructed by sandwiching the ends of two wire rods forming each horizontal beam between two wire rods forming each support and spot welding them together, a lightweight and strong structure can be obtained. In addition, the receiving shelf is formed by bending a continuous wire rod into a ring shape to form a pair of front and rear inverted U-shaped fitting parts and a supporting part extending horizontally from the lower end inside the side frame arrangement direction. If two mounting members are used on both sides, and a wire rod serving as a mounting part is installed between the supporting parts and integrally spot welded, a lightweight and inexpensive product can be obtained, and a product of any length can be obtained. This can be achieved by simply changing the length of the mounting section. Further, the engaging protrusion can be easily and strongly strengthened by spot-welding a pair of U-shaped wire rods or elongated loop-shaped wire rods to the inner surface of the fitting portion in the direction in which the side frame is disposed. can get.

An embodiment of the present invention will be described below based on the drawings. In Fig. 1, reference numeral 1 denotes a shelf made of wire rods, which has a pair of side frames 2a and 2b spaced apart from each other on the left and right, and is installed vertically at appropriate intervals between these side frames 2a and 2b. It consists of a plurality of receiving shelves 3. Each of the side frames 2a, 2b consists of a support 5 and a horizontal crosspiece 7, and as shown in FIGS. 1 and 2,
A pair of struts 5 made up of two wire rods 4 are arranged facing each other with an interval in a direction perpendicular to the arrangement direction of the wire rods 4, and two wire rods are arranged vertically at appropriate intervals between the struts 5, 5. A plurality of horizontal beams 7 consisting of 6 are installed. The two wire rods 6 constituting each horizontal beam 7 are arranged in parallel with an appropriate interval, and both ends of the wire rods 6 are sandwiched between the two wire rods 4 constituting the support column 5 and fixed together by spot welding. has been done. A pipe 19 for attaching casters and the like is welded to the lower end of the support column 5. As shown in FIGS. 3 to 6, the receiving shelf 3 is made up of mounting members 11 on both left and right sides and a mounting section 12 installed between them. The mounting member 11 has a fitting part 9 formed by bending a wire rod into an inverted U shape, and attaches the fitting part 9 to the pillars 5, 5 in the front and rear direction.
They are arranged at intervals such that they just fit in between them, and their one ends are connected to each other, and the other ends are connected to the side frames 2a, 2.
It is made up of a continuous annular wire 8 which extends inward in the arrangement direction b and has its ends connected to form a support 10. Said placement part 1
2 is constructed by spot-welding wire rods 13 in the left-right direction and wire rods 14 in the front-rear direction in a grid pattern, and is installed between the support portions 10 of the pair of left and right mounting members 11 and spot-welded together. On the inner surface of the fitting portion 9 in the direction in which the side frames 2a and 2b are disposed, a wire rod 15 bent into an elongated loop shape is spot-welded so that both ends thereof protrude outward from each fitting portion 9 in the front and back direction. The loop-shaped wire rod 15 has an engaging protrusion that engages with the inner side surface of the side frames 2a and 2b of the support column 5 in the direction in which the side frames 2a and 2b are disposed at both ends thereof that protrude outward from the fitting portion 9. 16 are configured. The ends of the wire rod 13 in the left-right direction of the mounting portion 12 extend to the lower surface of the loop-shaped wire rod 15 and are spot welded thereto. Further, a wire rod 17 is installed between both ends of the loop-shaped wire rod 15 that face each other in the left and right directions, and both ends of the wire rod 17 are spot-welded to the loop-shaped wire rod 15. 18 are configured. In addition, the aforementioned placement section 12
Both ends of the wire rod 14 in the front-rear direction are bent upward, and the ends are spot-welded to the inner surface of the wire rod 17 in the front-rear direction.

In the above configuration, shelf 1 must be assembled in the sixth position.
As shown in the figure, both ends of the receiving shelf 3 are placed in corresponding positions with the fitting parts 9, 9 above any horizontal bars 7, 7 of the side frames 2a, 2b,
The receiving shelves 3 are lowered in the direction of the arrow to fit the fitting parts 9, 9 to the horizontal bars 7, 7, and in this way, a desired number of receiving shelves 3 can be sequentially attached to any horizontal bars 7. When the receiving shelf 3 is installed, the side frame 2
Since the inverted U-shaped fitting portions 9 are fitted so as to sandwich the horizontal bars 7 of the side frames 2a and 2b from both sides, the side frames 2a and 2
b and the receiving shelf 3 are firmly connected and fixed, and the engaging protrusion 16 engages with the side surface of the support column 5 of the side frames 2a, 2b.
The support column 5 will be clamped through the side frame 2.
The rigidity of the connecting portion between a, 2b and the receiving shelf 3 is increased, and no horizontal vibration occurs, resulting in good stability.

According to the shelf of the present invention, as is clear from the above explanation, it is lightweight, inexpensive, and consists of a pair of side frames 2a, 2b and one or more receiving shelves 3 horizontally suspended between them. In addition, it is easy to handle, and an inverted U-shaped inverted U-shape on both sides of the receiving shelf 3 is attached to the horizontal bar 7 consisting of a set of two upper and lower wire rods 6, 6 installed between the supports 5, 5 of the side frames 2a, 2b. Since the fitting part 9 is fitted,
An inverted U-shaped fitting part 9 is prevented from moving accidentally by a horizontal bar 7 made of a set of two wire rods 6, 6 arranged vertically with a small interval, and is fixed in an accurate installation state. At the same time, even if a lifting force is applied in the direction of inclining the receiving shelf 3 from below, the inner surface of the inverted U-shaped fitting part 9 will not displace the lower wire rod 6 constituting the horizontal crosspiece 7.
It is possible to prevent the receiving shelf 3 from falling off by being locked to the shelf 3, and to prevent the placed articles from tipping over or falling down.

In addition, the engaging protrusions 16 protruding from the fitting portion 9 are engaged with the side surfaces of the support posts 5, so that the side frames 2a, 2b
The support shelf 3 can be firmly connected and fixed with high rigidity, and a stable shelf without risk of lateral vibration can be obtained.
