Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for casters that are attached to each corner of the lower surface of a display case.

Conventionally, the installation of casters in display cases involves attaching separately formed mounting brackets in a separate process from the assembly of the display case, and attaching them via these mounting brackets, which has the disadvantage of being time-consuming. Ta. Additionally, casters are generally installed so that they protrude from the corners of the display case due to the mounting position of the mounting brackets, so the casters become too conspicuous and spoil the aesthetics, and furthermore, when display cases are installed in a connected manner, There was a problem where adjacent casters came into contact with each other, making it difficult to connect them closely.

The purpose of this invention is to provide a mounting structure for a caster that eliminates these conventional drawbacks, and includes providing a notch on each isosceles side edge of a right-angled isosceles triangular mounting board, and fixing the caster between the notches. The pieces are erected and a lower frame receiving piece is formed that protrudes outward from the fixed piece in a portion other than the fixed piece, and with the lower frame receiving piece supporting the bottom corner of the display case, each fixed piece and The frame materials constituting the lower frame and the corner connectors are integrally tightened and connected using screws, and a screw hole for mounting a caster is provided at the center of the mounting board, and a screw hole for mounting a caster is provided in this hole. It is extremely easy to install by screwing the shaft, and the caster does not protrude into the corner, spoiling the aesthetics, or being placed next to each other so that it does not come into contact with the caster. .

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a mounting board in the form of a right-angled isosceles triangle, with notches 3, 3 provided on the side edges of isosceles 2, 2, respectively, and fixing pieces 4, 4 extending upright between the notches 3, 3. Set up and form. Holes 5, 5 are bored in the upper right and left positions of each fixing piece 4. On the other hand, at the side edges of each isosceles 2, receiving pieces 6, 6 which are flush with the mounting board 1 are extended at the portions which are removed from the notches 3, 3.
Furthermore, a raised portion 7 is provided at the center position of the mounting board 1,
A screw hole 8 is opened in the center to constitute a mounting bracket A. Note that the other side of the mounting board 1 has a reinforcing piece 9 formed by bending the edge upward.

Reference numeral 10 denotes a caster including a support shaft 11 screwed into the screw hole 8.

Next, the use of the mounting bracket A formed in this manner will be explained. In Fig. 2, 12 is each frame material 1
3 are connected in the X, Y, and Z coordinate axis directions via connectors 14. The connector 14 is integrally provided with a fitting shaft portion 16 that protrudes from three adjacent sides of the base portion 15 made of a rectangular parallelepiped while maintaining a right angle to each other, and into which the end portion of the frame member 13 is fitted. Screw holes 17 are bored in the side surface of each fitting shaft portion 16 at equal intervals from the base portion 15 .
Additionally, a hole 18 is formed on the inner surface of each frame member 13 constituting the lower frame.

Then, the frame member 1 is attached to each fitting shaft portion 16 of the connector 14.
3, and place the mounting bracket A on the inside of the orthogonal corner parts, and attach the fixing pieces 4, 4 to each frame member 13 with the receiving pieces 6, 6 supporting the lower surface of each frame member 13.
If the screw 19 is inserted through the hole 5 and screwed into the screw hole 17 provided in the fitting shaft 16 through the hole 18, the mounting bracket A will not be misaligned. Furthermore, the screws 19 that fix the mounting bracket A are screwed onto the fitting shaft portions 16 of the frame member 13 and the connector 14, so that they are firmly fixed. The screw 19 is inserted into the hole 5 as shown in FIG.
5 is formed thinner in the left-right direction than in the front-rear direction, and both the holes 5 and 5 are formed in the fitting shaft portion 1.
6 is provided at a constant distance from the base end of the mounting board 1, so in the left-right direction it can be inserted into the hole 5 closer to the tip of the mounting board 1, and in the front-rear direction it can be inserted into the hole 5 closer to the reinforcing piece 9. .

If the caster 10 is mounted by screwing the support shaft 11 into the screw hole 8 provided in the center of the mounting board 1 of the mounting bracket A mounted in this way, the caster 10 will be attached to the frame member that is perpendicular to each other at each corner. It is mounted inside the corner 13 and does not protrude from the corner.

Further, instead of the caster 10, an adjuster can be screwed into the screw hole 8 to freely adjust the height.

As described above, the caster mounting structure of the present invention is such that when assembling a display case, when fitting the frame material to each fitting shaft part of the connector, the caster mounting bracket is placed on the inside of the perpendicular points. Then, with the receiving pieces protruding outward from each fixing piece of the mounting board supporting the lower surfaces of each frame member perpendicular to each other, tighten each fixing piece, each frame member, and the connector together with screws. The caster can be connected and fixed securely without any hassle, and since the caster is attached to the screw hole provided in the center of the mounting board, it is retracted from the corner of the lower frame, making it unobtrusive and aesthetically pleasing. There's nothing to lose. Since the casters are retracted from the corners in this way, when the display cases are installed in a connected manner, adjacent casters do not come into contact with each other, and the display cases can be connected in close contact. There are so many advantages.
