双层翻转沙发床Double flip sofa bed
本发明涉及双层床技术领域，尤其是涉及能多功能够实现翻转折叠的沙发床。The invention relates to the technical field of bunk beds, in particular to a sofa bed which can be multi-functionally realized to realize flip folding.
顾名思义，沙发床就是一种既可作为沙发也可作为床铺使用的家具，使用沙发床的原因可能有许多种，基本上仍与空间的利用有关，由于沙发床具有沙发和床铺两种用途，而且在沙发形态时又可以缩小占用的空间，对于空间有限或是注重个人空间的使用者而言，实为一种实用的家具。As the name suggests, the sofa bed is a kind of furniture that can be used as a sofa or as a bed. There may be many reasons for using the sofa bed, which is basically related to the use of the space, because the sofa bed has two purposes, namely, a sofa and a bed. In the form of a sofa, it can reduce the occupied space, which is a practical furniture for users with limited space or personal space.
已知的沙发床有许多不同的设计与造型，其中一种是采用两个彼此迭置在一起的软垫和一个作为沙发椅背的背靠垫所组成，彼此迭在一起的两个软垫通常是利用布料或是沙发的表面材料连接在一起，迭在上方的软垫在沙发形态时作为椅面，下方的软垫作为沙发椅座或椅脚；要变为床铺时，上方的软垫被翻开和下方的软垫一齐平放于地面，再将背靠垫一齐摊平在地面就变成了一张床铺；这种沙发床的构造极为简单，可是在展开为床铺使用时，作为椅面或是床面的部份可能会有部份共享，使得椅面成为床面的一部分，显然不太卫生；甚至于在展开为床铺使用时，有大部份的表面会贴放于地面而容易弄脏了沙发床的表面，如果在移动时不小心又可能会令沙发床的表面受损。Known sofa beds have many different designs and shapes, one of which consists of two cushions that are placed one on top of the other and a back cushion that is a sofa back. It is connected by the surface material of the fabric or the sofa. The cushion above is used as the seat surface in the form of the sofa, and the cushion under the seat is used as the sofa seat or the chair foot; when it becomes the bed, the upper cushion is Open and the lower cushions are laid flat on the ground, and then the back cushions are flattened on the ground to become a bed; the structure of the sofa bed is extremely simple, but when used as a bed, it is used as a seat Or the part of the bed may be partially shared, making the seat surface part of the bed surface, which is obviously unsanitary; even when it is deployed as a bed, most of the surface will be placed on the ground and easy. The surface of the sofa bed is soiled, and if it is accidentally moved, the surface of the sofa bed may be damaged.
Another known sofa bed structure, in the form of a sofa, the underlying cushion is provided with a leg to prevent the bottom surface of the sofa bed from contacting the ground and being soiled or damaged, but the sofa bed is usually set There are handrails. In addition to the function of supporting the arm in the form of a sofa, when the handrail is deployed in the form of a bed, the handrail is used as a support for the other part of the foot or the bottom of the bed. Therefore, the surface of the handrail is still easy. Dirty or damaged.
针对这样的技术问题，专利公告号为202567262U，名为“沙发床”的技术方案，其包括基础结构，具有基底架和背架，背架固定立设于基底架的后侧；下铺机构，具有下床组和四连杆机构，下床组藉由四连杆机构装置于基底架，可以从沙发形态的位置移动至下铺形态的位置；和上铺机构，具有上床组和翻转支撑机构，上床组具有椅面和床面，在沙发形态时，上床组迭置于下床组之上且椅面向上，下床组可藉由翻转支撑机构先举升至一翻转高度，再将上床组翻转成为床面向上的上铺形态，举升翻转的过程中翻转支撑机构还会连动下铺机构移动至下铺形态的位置。该技术通过连杆机构实现上下双层床的叠加在一起以成为沙发，该沙发床使用不方便。For such technical problems, the patent publication number is 202567262U, a technical solution named "Sofa Bed", which comprises a basic structure, has a base frame and a back frame, the back frame is fixedly erected on the rear side of the base frame; The utility model has a lower bed group and a four-bar linkage mechanism, wherein the lower bed group is arranged on the base frame by the four-bar linkage mechanism, and can move from the position of the sofa shape to the position of the lower bunk shape; and the upper laying mechanism has the upper bed group and the flip support mechanism The upper bed group has a seat surface and a bed surface. In the form of a sofa, the upper bed group is placed on the lower bed group and the chair is facing upward, and the lower bed group can be lifted up to a flip height by turning the support mechanism, and then going to bed The group is turned into an upper bunk form with the bed facing upward, and the flip support mechanism also moves the lower bunk mechanism to the position of the lower bunk shape during the lifting and flipping process. This technology realizes the superposition of the upper and lower bunk beds by the link mechanism to become a sofa, which is inconvenient to use.
中国专利公告号为：202604221U，名为“翻转式多功能沙发床”的技术公开了这样一种技术，包括有下床体和上床体，该下床体具有一收纳上床体的容置空间，该上床体与下床体可翻转地枢接，当上床体相对下床体向上翻转到位后，该上床体位于下床体的上方而形成双层床结构，当上床体相对下床体向下翻转到位后，该上床体收纳于该容置空间中而形成沙发结构；藉此，取代了传统之沙发床功能单一打开后仅能作为一个床铺使用的方式，从而使得在狭小的房间里满足节约空间的目的，为人们的使用带来更多便利性。但是，该技术也存在不足之处，例如其实通过一个气压杆实现上下翻转，而且在展开为床的时候，仅仅通过折叠梯来固定支撑，使用时存在很大的安全隐患。The Chinese Patent Publication No. 202604221U, the technology named "Flip-type multifunctional sofa bed" discloses such a technology, comprising a lower bed body and an upper bed body, the lower bed body having a receiving space for accommodating the upper bed body. The upper bed body and the lower bed body are pivotally connected to each other. When the upper bed body is turned upside down relative to the lower bed body, the upper bed body is located above the lower bed body to form a bunk bed structure, when the upper bed body is opposite to the lower bed body. After being turned into position, the upper body is received in the accommodating space to form a sofa structure; thereby, instead of the traditional sofa bed function, the utility model can only be used as a bed after a single opening, thereby making saving in a small room. The purpose of space is to bring more convenience to people's use. However, this technology also has shortcomings, for example, it is actually turned upside down by a gas pressure rod, and when it is unfolded into a bed, the support is fixed only by folding the ladder, and there is a great safety hazard in use.
该技术功能齐全，在张开时可作为上下双层床使用，在折叠情况下可单独作为沙发使用，满足不同的家庭需求，同时大大节省了家居空间。该技术中，通过旋转轮来实现上下床体的翻转，在展开为双层床时，通过长方形支撑脚来固定支撑，使得上床体不稳定，同样存在很大的安全隐患。In addition, the Chinese Patent Bulletin No. 202457386U, the technical solution named "Bank's functional sofa bed" proposed a scheme: Among them: the sofa structure includes: round armrest, three-piece backrest, double-layer cushion, rectangular metal feet The bunk bed structure includes: upper bed frame, lower bed frame, bed support frame, lower bed support frame, guardrail and ladder frame, rotating wheel and telescopic link, ladder frame switch; Bank function sofa, bed support frame by rotation The wheel and the telescopic connecting rod are foldably connected with the lower bed support frame, so that the sofa and the bunk bed are mutually converted, and the upper bed support frame and the lower bed support frame are folded into a circular armrest of the sofa, and the upper bed frame and the lower bed frame are turned into double The layer seat cushion, wherein the upper bed support frame is a lower seat cushion, and the lower bed support frame is an upper seat cushion.
The technology is fully functional and can be used as an upper and lower bunk bed when it is opened. It can be used as a sofa alone in the case of folding, which can meet different family needs and greatly save the home space. In this technique, the turning of the upper and lower bed bodies is realized by rotating the wheel, and when the double bed is unfolded, the support is fixed by the rectangular supporting feet, so that the upper body is unstable, and there is also a great safety hazard.
