Description

The present invention relates to a human load loading device, particularly a movable human load loading device.

Relaxing entertainment and leisure activities are needed for those who have to endure the stress of daily life and the sense of responsibility required in the workplace as the socio-economic development progresses. For example, many people choose a karaoke box when they want to sing and enjoy karaoke. Traditional karaoke boxes cannot satisfy all consumers due to restrictions on the number of people, time and place. Compared to conventional karaoke boxes, mini karaoke boxes that look like public telephone booths are not only cheaper to use, but also have no restrictions on the number of people or time, so they are accepted by many consumers.

The above-mentioned mini karaoke box is generally installed in a commercial area, a department store, a movie theater area, etc., and the installation location is generally adjusted by performing indoor remodeling of the building at regular intervals. The mini karaoke box is installed directly on the ground and has a constant weight. When adjusting the installation location and moving the mini karaoke box, you have to rely on the equipment. In other words, the mini karaoke box has relatively poor mobility.

A main object of the present invention is to provide a movable human load loading device that improves maneuverability during use by providing good supportability and mobility.

In order to solve the above-mentioned problems, the movable human load loading device includes a pedestal, a plurality of casters, and a plurality of legs. The plurality of casters are mounted on the pedestal so as to project from the bottom surface of the pedestal. The plurality of legs are mounted on the pedestal and can be vertically displaced between the first and second positions with respect to the pedestal. When the plurality of legs are placed in the first position, the position of the bottom surface of the plurality of legs does not exceed the position of the bottom surface of the plurality of casters. When the plurality of legs are placed in the second position, the position of the bottom surface of the plurality of legs is higher than the position of the bottom surface of the plurality of casters.

Due to the structural features described above, the movable human load loading device according to the present invention can be used by switching according to actual needs. More specifically, if the plurality of legs are placed in the first position, the pedestal can be stabilized on the ground without being freely moved by the plurality of legs. If the plurality of legs are placed in the second position, the pedestal can be freely moved by the plurality of casters to facilitate the transportation work.

When relatively preferred, the pedestal has a support frame and a top plate. The support frame has a plurality of screw holes. The top plate is mounted on the top surface of the support frame and has a plurality of top plate holes. Each of the legs has a leg cap and a bolt. Since the bolts of the plurality of legs are respectively tightened in the screw holes of the support frame, the plurality of legs can be vertically displaced between the first position and the second position with respect to the pedestal. The tip of the bolt is inserted into the top hole of the top plate, and the end is connected to the leg cap. When the multiple legs are placed in the first position, the tips of the multiple bolts are hidden in the top hole. The position of the bottom of the multiple leg caps does not exceed the position of the bottom of each caster. When the plurality of legs are installed in the second position, the tips of the plurality of bolts are each exposed to the top plate hole. The positions of the bottoms of the multiple leg caps are higher than the positions of the bottoms of the casters.

If relatively preferred, the pedestal further has a bottom plate. The bottom plate is mounted on the bottom surface of the support frame and has a plurality of bottom plate holes and a plurality of storage grooves. The bolts on the multiple legs each penetrate the bottom plate hole. Each of the plurality of casters is stored in the storage groove of the bottom plate.

When relatively preferred, the support frame has a housing, a plurality of ribs, a plurality of caster holders and a plurality of leg supports. The plurality of ribs are connected to the inner peripheral surface of the housing. The plurality of caster holders are connected and fixed between the inner peripheral surface of the housing and one rib. Each of the plurality of casters is attached to the caster holder. Each of the plurality of leg supports has a screw hole.

When relatively preferred, each caster holder has two opposing side surfaces. Each side surface has a shaft hole. Each caster is rotatably mounted on the axle. Each axle separately has both ends penetrating the shaft holes on the side surfaces of the caster holders, and has separate fitting grooves and fitting rings located within the fitting grooves at both ends. The fitting ring prevents the axle from deviating from the casters and completes the caster mounting work.

If relatively preferred, each caster has multiple perforations. The perforations each penetrate the two opposing end faces of the caster and are arranged in a ring at intervals from the center of the caster.

When relatively preferred, the pedestal moves only in the linear direction.

The housing 31 has a quadrilateral shape and has two opposing first frames 32 and two opposing second frames 33. Both ends of the first rib 34 are separately connected to the inner peripheral surfaces of the two first frames 32. Both ends of each second rib 35 are separately connected to the inner peripheral surfaces of the two second frames 33. Each second rib 35 is vertically connected to the first rib 34 and is arranged along the first rib 34 at regular intervals. As shown in FIG. 8, the four caster holders 36 are located at the four corners of the housing 31 and have a top surface 366 located between the two side surfaces 362 and the two side surfaces 362, respectively. The two side surfaces 362 each have a shaft hole 364, and the outer peripheral surfaces are separately connected to the first frame 32 and the second rib 35 closest to the first frame 32. The four leg support portions 37 are located at the four corners of the housing 31, and have screw holes 372 that penetrate the top surface and the bottom surface, respectively. The four leg supports 37 are connected between the first frame 32 and the second rib 35 closest to the first frame 32, respectively.

The pedestal 20 further has a quadrilateral top plate 40 and a quadrilateral bottom plate 50. The top plate 40 is positioned above the support frame 30 and is mounted on the top surface of the support frame 30. The bottom plate 50 is positioned below the support frame 30 and is attached to the bottom surface of the support frame 30 by a tightening method. The top plate 40 has separate top plate holes 42 at four corners. The bottom plate 50 has a bottom plate hole 52 and a storage groove 54 separately at four corners.
