Abstract

(57) [Problem] To provide a new caster-equipped walker with a caster provided with a stand for landing while the caster is floating. SOLUTION: In a baby walker provided with a plurality of freely turning casters 1 on a lower surface of a lower frame 2 at substantially equal intervals, a U-shape is formed on a lower surface of a rear side or a front side of the lower frame 2. The stand member 14 is supported up and down freely, and when the stand member 14 is in the upright state, the support end 15 enters the upright hole 16 provided in the lower frame 2 to maintain the upright state and maintain the upright state. In the state, when the lower end side of the stand member 14 lands, the caster located at the rear position or the front position is lifted from the ground, and when the support end portion 15 is pulled out from the upright hole 16 to be in the lying state, the base member on the left and right sides of the stand member 14 is set. The end portion abuts on the protruding portion 17 to maintain the lying state.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a caster with a caster, and more particularly, to a caster with a caster provided with a stand on which a caster located on a rear side or a front side is landed in a floating state.

[0002]

[Prior art]

 Conventionally, bicycles and the like are known as devices that are used to suspend a vehicle by suspending a rear wheel by a stand.

[0003]

[Problems to be solved by the invention]

 The stand described in the related art described above has a structure in which a standing state and a falling state are maintained using a spring.

[0004] However, since this uses a spring, the structure is complicated, and assembly and disassembly are complicated and difficult. There is also an undesired problem such as not being suitable for infant walkers because it may give a danger of not being able to do so.

[0005] An object of the present invention is to provide a new caster-equipped walker equipped with casters that has been devised to solve the above-mentioned defects and problems.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the infant walker with casters according to the present invention comprises a lower walker provided with a plurality of slewing casters on the lower surface of the lower frame at substantially equal intervals. A stand member 14 having a U-shape is supported on the lower surface of the rear side or the front side so as to be able to undulate, and when the stand member 14 is raised, the support end 15 is provided on the lower frame 2. In this state, the lower end of the stand member 14 lands and the caster located at the rear position or the front position is lifted from the ground and the support end 15 is raised. When the stand member 14 is pulled out of the stand member 16 and brought into the lying state, the left and right base portions of the stand member 14 abut on the projections 17 to maintain the lying state.

【Example】

 In the embodiment shown in the figure, an oblong lower frame 2 provided with a plurality of deflectable casters 1 on the lower surface at substantially equal intervals is formed, and a rectangular box type model of a vehicle is formed on the lower frame 2. A body 3 having a shape and having open ports on upper and lower surfaces is arranged, and an edge of a lower open port of the body 3 is fixed to the upper surface of the lower frame 2 so as not to be detachable. An upper frame 4 having an elliptical shape is fixed to the edge of the upper opening so that the upper opening 4 of the body 3 is located rearward, and a dish-shaped wall 6 is provided in the front half of the upper frame 4. A recess 7 is formed in the same, and a horizontal rail 8 is formed at the rear side of the recess 7 and extends from the rear edge of the dish-shaped top wall 6 and has a cross section having an inverted U-shape. In addition, a walker main body 11 is configured by vertically hanging an adjustment fitting 9 for an infant 9 on the rear side of the upper frame 4 and the horizontal rail 8.

In the upper frame 4, the left and right grips 12 are located at positions on the left and right sides of the mounting portion of the seating member 10, and the gripping portion for a child who can stand up to play at the position located on the rear side is also used. 13 are provided.

A U-shaped stand member 14 is supported on the lower surface of the rear side of the lower frame 2 so as to be able to move up and down. When the stand member 14 is in the raised state, the support end 15 is previously lowered. The standing member 14 is inserted into the upright hole 16 provided in the frame 2 to maintain the raised state by the press contact of the projection 41 provided on the wall surface of the upright hole 16. The caster at the position is to be lifted off the ground, and when the stand member 14 is in the down state, the base end portions on the left and right sides of the stand member 14 are in contact with the projections 17 to maintain the same state.

Further, a mounting base 19 having substantially the same shape as the recess 7 is formed separately from the walker main body 11. On the upper surface of the mounting base 19, an idling type driving handle toy part 20 and an abacus toy part are provided. The card (not shown) inserted therein changes when rotated by finger 21 and the card toy unit 22 and the built-in spring (not shown) generates a sound when the disk is turned by finger. A sounding toy part 23 to be emitted and a sounding toy part 24 that emits a whistle sound when pressed and released by hand are provided, and the mounting base 19 is removably fitted into the recess 7. The engagement between the engagement pin 25 and the engagement hole 26 and the engagement between the engagement projection 27 and the trip operation member 29 which is returned by the spring 28 are maintained.

Furthermore, a symbol decoration board member 30 provided with an emblem or a character (not shown) on its surface is formed separately from the walker body 11 and the toy mount 19. A plurality of mounting pins 32 having a huge head 31 at the front end on the back surface of the member 30 are provided at equal intervals on one circular line, and a symbol decoration is provided at the center of the front of the body 3 of the walker body 11. A portion 34 is provided, and a portion of the symbol decoration portion 34 on a circle having the same radius as the above-mentioned circle is along the same line which is wider than the thickness of the leg of the mounting pin foot 32 and narrower than the outer shape of the enlarged head 31. A plurality of elongated holes 35 having an arc shape are opened, and an insertion hole 36 having a diameter slightly larger than the outer diameter of the enlarged head 31 is continuously provided at one end of each of the elongated holes 35. The mounting pin feet 32 of the decorative board-shaped member 30 are inserted into these insertion holes 36. The mounting pin foot 32 is moved to the other end of each of the slots 35 by rotating the decorative disc-shaped member 30 along the outer surface of the symbol decorative portion 34 after passing through the entirety of the decorative disc-shaped member. 30 is attached.

In the drawing, reference numeral 38 denotes a colored soft synthetic resin landing member attached to both corners of the stand member 14, and reference numerals 39 and 40 denote soft synthetic resin bumpers attached to the front and rear surfaces of the lower frame 2.

[Effect of the invention]

 The infant walker with casters according to the present invention comprises a rear walker of the lower frame 2 in an infant walker provided with a plurality of turnable casters 1 on the lower surface of the lower frame 2 at substantially equal intervals as described above. Alternatively, a stand member 14 having a U-shape is supported on the lower surface of the front side so as to be able to move up and down. In this state, the lower end of the stand member 14 lands and the caster at the rear position or the front position is lifted from the ground, and the support end 15 is pulled out from the upright hole 16 to fall down. In this state, the left and right base portions of the stand member 14 abut on the projections 17 to maintain the laid state. Be one that causes the going on spring does not need, this such defects, and has significant effects that can completely eliminate the problem.
