Description

The clamping device of foldable bed

The utility model relates to a kind of clamping device, is meant that especially a kind of two skeleton frame appropriate locations at foldable bed are provided with a location mechanism, so as to keep the parallel clamping device of two main frames when foldable bed folds.

Can be when foldable bed is a kind of the expansion for the special-purpose bed accessory that crouches and lie, easily collect again when folding, the foldable bed that has in design is up to amount to, that is to say, make and have mattress one side and fit, though this bed accessory of up amounting to is very convenient in collection, but because it folds Hou is to make the closing of mattress phase, therefore must take out cotton-wadded quilt earlier when folding, desirable not to the utmost in the use; In order to improve aforementioned disadvantages, occur on the market a kind of fold Hou still can be for the foldable bed of cotton-wadded quilt coating, this foldable bed mainly is to adopt the mode of amounting to downwards, just make the mutual closing in main frame bottom of setting up mattress, and the mattress position is in the outside that folds the Hou bed accessory, so cotton-wadded quilt just can be coated on the mattress, and the utility model is exactly can to make improvements for the foldable bed that the cotton-wadded quilt coating is put at this.

Consulting Fig. 1,2, is a kind of stereo appearance figure and expansion side view of traditional foldable bed, and traditional foldable bed 1 is to shore seat 11 left sides one to assemble a left skeleton frame 12, and a right skeleton frame 13 is installed on its right side; Wherein, shoring seat 11 is to establish a strut 112 at 111 folders of pin-jointing piece of two pairs of parallel correspondences, is provided with two grabs 113 in strut 112 bottoms; And left skeleton frame 12 comprises a main frame 121 and a foot rest 122, two parallel ends of above-mentioned main frame 121 utilize a pivot 123 to be hubbed on 111 of both sides pin-jointing pieces respectively, its end face is assembled a mattress 10, install foot rest 122 at main frame 121 away from the outside of shoring seat 11, above-mentioned foot rest 122 has two socles that extend downwards, and each socle bottom is installed a castor 124 respectively; And right skeleton frame 13 is made up of a main frame 131 and a runners 132, two parallel ends of wherein main frame 131 also borrow a pivot 133 to be hubbed on 111 of two groups of pin-jointing pieces respectively, also assemble a mattress 10 on main frame 131 tops, and runners 132 comprises the sole 134 of two correspondences, two soles 134 are hubbed on the outer side surface of main frame 131 respectively by a fulcrum 130, connect a connecting rod 135 on 134 on two soles, assemble two castors 136 respectively in each sole 134 bottom; Foldable bed 1 folds for convenience, and wherein 121 hooks of a grab 113 and main frame are established a spring 14, and 131 hooks of another grab 113 and main frame are established another spring 15.

Under the state that launches, the strut 112 of shoring seat 11 is that support is located at ground, and the castor 124,136 of left and right skeleton frame 12,13 also supports to arrive on ground, and two main frames 121,131 of foldable bed 1 were parallel to each other and can lie for crouching this moment, and the spring 14,15 item of position in the bottom is stretched condition.

Cooperate Fig. 2,3, wherein Fig. 3 is the schematic representation that folds of traditional foldable bed, carries on earlier in the time of folding foldable bed 1 and shores seat 11, just can borrow spring 14,15 with on the left and right main frame 121,131 away from shoring the past middle drawing of seat 11 1 ends, to reach the purpose that folds; If cotton-wadded quilt will be collected together, then under the state that foldable bed 1 launches, cotton-wadded quilt is tiled on the two main frames 121,131, so shore seat 11 by on when carrying, cotton-wadded quilt will be put on a suit of armour on two main frames 121,131 Zhe, reaches the purpose of collecting cotton-wadded quilt in the lump whereby.

Though this traditional foldable bed 1 gets a desired effect in design, but when folding because main frame 131 and 132 of runners are serve as to articulate the fulcrum swing that can make progress of dying with fulcrum 130, and connecting rod 135 outsides by being located at runners 132, and left skeleton frame 12 can be subjected to spring 14,15 are pulled relies on main frame 131, by establishing Hou since 134 on main frame 131 and sole only it can be swung at any time for the pivot joint state, also be higher than castor 136 and originally support folding Hou at the foot rest 122 on ground, therefore, articulate with fulcrum 130 at main frame 131, and under the situation of attaching most importance to than the right side in the left side of main frame 131, whole foldable bed 1 can the pendulum of inclination left; The above-mentioned pendulum that inclines that folds the Hou nature is coated on cotton-wadded quilt on the foldable bed 1 if add the user, then have slightly outer try hard to recommend and, whole foldable bed 1 just is easy to generate the danger of toppling over, obvious traditional foldable bed 1 is no doubt convenient in the use, but it folds Hou because can't held stationary, therefore, produce the danger of toppling over easily in use, this is the part that haves much room for improvement in traditional foldable bed 1 design.

For this reason, main purpose of the present utility model is that a kind of clamping device of promoting the foldable bed that folds Hou steadiness and Security is being provided.

Foldable bed of the present utility model is to shore the both sides skeleton frame that respectively is pivoted one, each skeleton frame all has a main frame, wherein a main frame is away from the position runners that is pivoted of shoring seat, another main frame relative position foot rest that is pivoted, but assemble a drawing two main frames respectively between seat and two main frames and make its upright parallel spring that folds shoring; Wherein, establishing one between two skeleton frame groups makes two main frames keep parallel when folding, can prevent to fold the flared positioning means of two skeleton frames of Hou, this positioning means can be the bond layout between pin and positioning hole, comprise that one is molded over the aperture on the sole that is provided with runners, one is molded over positioning hole and the pin on the skeleton frame that is provided with foot rest, wherein, positioning hole and aperture can be upright axially corresponding when parallel at two main frames, and pin can pass the positioning hole and the aperture of aforementioned axial correspondence; Also can be the snap-on design of grab and card intercolumniation; Borrow the design of aforementioned positioning means, make two main frames be maintained to each other parallel folding Hou, and therefore improve stationarity and the Security that foldable bed folds Hou.

By above explanation as can be known, the utility model with spring as the folding chair of the means of folding on the appropriate location be provided with one the location mechanism, above-mentioned positioning means can be and utilizes positioning hole, the mode that installs that cooperates between aperture and pin, also can be the device that hooks together of clamp and card intercolumniation, it is except can being provided with position as shown in the Examples, also can be arranged on the position of main frame top according to need, exactly near shoring a position, borrow the design of aforementioned positioning means, really can fold Hou at foldable bed and make two main frame keeping parallelisms, to promote the steadiness that foldable bed folds Hou, and prevent foldable bed balance and toward lopsidedness for want of when folding together with cotton-wadded quilt, that is to say that the improvement of the utility model aforementioned means has preferable steadiness and the Security that folds Hou.
