本发明涉及一种折叠桌, 尤其是指一种可调桌面大小的折叠桌。 背景技术 The invention relates to a folding table, in particular to a folding table with adjustable desktop size. Background technique
现代的家具中,无论是家居家具或是办公家具,为提高其实用性, 则在其功能上的要求都愈来愈高,因此具可折叠功能的家具便应运而 生。如图 1所示即为可适用于野外活动的折叠式桌子,其主要由桌面 1, 及桌架 2, 组成, 桌架 2, 包括横梁 21,、 纵梁 22,、 两组桌腿 23, 及两支撑杆 24,, '其中横梁 21, 是固定于桌面 Γ 的底面,纵梁 22' 是分别枢接于两横梁 21, 的两端及中央; 两组桌腿 23, 分别固定于 两端的纵梁 22, 上; 支撑杆 24, 的一端固定于桌腿 23, 上, 另一 端则枢接于横梁 21, 中央的纵梁 22, 上。 Among modern furniture, whether it is home furniture or office furniture, in order to improve its practicality, the functional requirements are becoming higher and higher, so furniture with foldable functions has come into being. As shown in Fig. 1, a folding table suitable for outdoor activities is mainly composed of a table top 1 and a table frame 2. The table frame 2 includes a beam 21, a stringer 22, and two sets of table legs 23. And two supporting rods 24, 'where the beam 21 is fixed to the bottom surface of the tabletop Γ, and the beam 22' is pivotally connected to both ends and the center of the two beams 21, respectively; two sets of table legs 23 are fixed to the two ends One end of the longitudinal beam 22, is fixed to the table leg 23, and the other end is pivotally connected to the cross beam 21, and the central longitudinal beam 22 ,.
当欲携带或收藏时, 将桌面 1, 朝下, 向下扳动桌腿 23, 施力, 由于桌腿 23, 与纵梁 22,、 支撑杆 24, 与桌腿 23, 的枢接关系, 桌 腿 23,便会收靠于桌面 1, 的底面上,以缩小其体积实现折收的功能。 When you want to carry or store it, push the table top 1 downwards and pull the table legs 23 down to apply force. Due to the pivotal relationship between the table legs 23, the longitudinal beams 22, the support rods 24, and the table legs 23, The table legs 23 will rest on the bottom surface of the table top 1 to reduce its volume and achieve the function of folding.
但是该结构的折叠桌中, 桌面 Γ 的面积是固定的, 无法灵活适 用于人数多寡的情况。 However, in the folding table of this structure, the area of the tabletop Γ is fixed, and it cannot be flexibly adapted to the number of people.
发明内容 Summary of the Invention
本发明目的是提供一种桌面的面积大小可以调节的折叠桌。 为达成上述目的, 本发明的解决方案是: 可调折叠桌, 由桌面与 桌架组成,其中桌架包括两横梁、至少两纵梁、两桌腿组及两支撑杆, 其中桌面包括由两个卡扣拼接的主桌面与至少一个副桌面,在各桌面 确 认 本
下方分别对塑料布两横梁成型有配合滑槽。 The object of the present invention is to provide a folding table with adjustable area. To achieve the above object, the solution of the present invention is: an adjustable folding table composed of a table top and a table stand, wherein the table stand includes two beams, at least two longitudinal beams, two table leg groups, and two support rods, wherein the table top includes Main desktop and at least one secondary desktop Cooperating chutes are respectively formed on the two beams of the plastic cloth below.

具体实施方式 detailed description
如图 2、 3、 4所示, 本发明的一种折叠桌, 其亦主要由桌面 1及 桌架 2组成, 桌面 1包括两主桌面 11及至少一个副桌面 12 (本实施 例中为两个副桌面); As shown in FIGS. 2, 3 and 4, a folding table of the present invention is also mainly composed of a table top 1 and a table frame 2. The table top 1 includes two main table tops 11 and at least one sub table top 12 (two in this embodiment). Sub-desktops);
两主桌面 11的下方成型有滑槽 111,在滑槽 111内固定有槽钢 3, 在两主桌面 11的相对面上分别成型有相互扣合的凸出部 112及凹陷 部 113, 在凸出部 112与凹陷部 113相配合的表面上设有凸垣 1121 与凹槽 1131; 在主桌面 11的下表面上设有扣合副桌面 12的凹陷部 114; 在凹陷部 114相配合的表面上亦设有凹槽 1141; Sliding grooves 111 are formed below the two main tabletops 11, and channel steel 3 is fixed in the sliding grooves 111. On the opposite sides of the two main tabletops 11, convex portions 112 and recessed portions 113 that are fastened to each other are respectively formed. A convex portion 1121 and a groove 1131 are provided on a surface matching the outlet portion 112 and the concave portion 113; a concave portion 114 which is engaged with the auxiliary desktop 12 is provided on the lower surface of the main desktop 11; and a surface matching the concave portion 114 There are also grooves 1141;
副桌面 12的两侧面上亦成型有对应配合两主桌面 11 的凸出部 121及凹陷部 122,并在其配合的表面上亦设有凸垣 1211与凹槽 1221; 对应上述主桌面 11的凹陷部 114, 在副桌面 12的下方亦成型有凸出 部 123, 在其配合的表面上亦设有凸垣 1231; A convex portion 121 and a concave portion 122 corresponding to the two main table tops 11 are also formed on the two side surfaces of the auxiliary table top 12, and a convex wall 1211 and a groove 1221 are also provided on the mating surface; corresponding to the above main table 11 The recessed portion 114 is also formed with a protruding portion 123 under the sub tabletop 12, and a convex ridge 1231 is also provided on the mating surface;
桌架 2包括两横梁 21、 四纵梁 22、 两组桌腿 23及两支撑杆 24, 其中横梁 21是与槽钢 3活动套合在一起; 在横梁 21与槽钢 3之间 加设有防止横梁 21槽钢 3之间发生晃动的支撑块 4, 支撑块 4是固 定于槽钢 3上, 并可相寸横梁 21滑滑; The table frame 2 includes two cross beams 21, four longitudinal beams 22, two sets of table legs 23, and two support rods 24, where the cross beam 21 is movably fitted with the channel steel 3; an additional arrangement is provided between the cross beam 21 and the channel steel 3. The support block 4 to prevent shaking between the channel steels 3 of the cross beam 21, the support block 4 is fixed on the channel steel 3, and the cross beam 21 can slide smoothly;
纵梁 22是分别枢接于两横梁 21的两端及中央; 两组桌腿 23分 别固定于两端的纵 22上; 支撑杆 24的一端固定于桌腿 23上, 另一 端则柩接于横梁 21中央的纵梁 22上。 The longitudinal beams 22 are pivotally connected to the two ends and the center of the two transverse beams 21; two sets of table legs 23 are respectively fixed to the longitudinal 22 at both ends; one end of the support rod 24 is fixed to the table legs 23, and the other end is connected to the transverse beams 21 the central stringer 22.
组合时, 如图 4所示, 将两主桌面 11架于桌架 2上后, 两主桌
面 11各凸出部 112与各凹陷部 113分别卡扣配合在一起便組成一桌 子。 When combined, as shown in FIG. 4, after the two main desks 11 are mounted on the table rack 2, the two main desks The convex portions 112 and the concave portions 113 of the surface 11 are respectively snap-fitted together to form a table.
如图 5、 6所示, 当桌面 1的面积需要较大时, 用力将两主桌面 11拉开一段距离, 此时由于各主桌面 11下的槽钢 3与桌架 2的横梁 21是套合在一起,则桌面 11可以带动槽钢 3及支撑块 4相对横梁 21 滑移,再将副桌面 12扣合在两主桌面 11之间, 利用各桌面的凸出部 与各凹陷部的配合卡扣, 便组成一桌面 1面积较大的桌子。 As shown in Figures 5 and 6, when the area of the table top 1 needs to be large, the two main table tops 11 are pulled apart for a certain distance. At this time, since the channel steel 3 under each main table top 11 and the beam 21 of the table frame 2 are sleeves Together, the table top 11 can drive the channel steel 3 and the support block 4 to slide relative to the cross beam 21, and then the auxiliary table top 12 is fastened between the two main table tops 11. The cooperation of the projections and depressions of the table tops is used. The buckle forms a large table with a table top and an area.
如图 7所示, 当桌面 1的面积需要更大时,可加设两块甚至更多 块副桌面 12即可实现。 As shown in FIG. 7, when the area of the desktop 1 needs to be larger, two or more sub-desktops 12 can be added to achieve this.
如图 8所示, 当折收本发明的折叠桌时, 先将副桌面 12从两主 面 1.1上拆下, 两主桌面 11拼接后朝下, 向下扳动桌腿 23施力, 由 于桌腿 23与纵梁 22、 支撑杆 24与桌腿 23的枢接关系, 桌腿 23便 会收靠于桌面 1的底面上, 再将两副桌面 12利用其下方成型的凸出 部 123扣合于主桌面 11下表面的凹陷部 114内, 以实现缩小其折收 体积功能。 As shown in FIG. 8, when folding the folding table of the present invention, the auxiliary table top 12 is first removed from the two main surfaces 1.1, the two main table tops 11 are spliced downward, and the table legs 23 are pulled downward to exert force. The pivotal relationship between the table legs 23 and the longitudinal beams 22, the support rods 24 and the table legs 23, the table legs 23 will rest on the bottom surface of the table top 1, and then the two table tops 12 will be buckled by the protruding portions 123 formed below them. It fits into the recessed portion 114 on the lower surface of the main table top 11 to achieve the function of reducing its folded volume.
工业应用, Industrial applications,
由于此折叠桌的两主桌面可以相对桌架的两横梁滑动,当桌面的 面积需要较大时, 可将两主桌面相对横梁向两侧移动,将副桌面拼接 于两主桌面之间并架于横梁上,便形成一大面积的桌面; 当桌面的面 积需要较小时, 将副桌面拆下即可; 在此折叠桌折叠后, 副桌面可以 扣合在主桌面的下表面上,而不用占用过多的体积,因而其使用便利, 实用性较强。
Since the two main tabletops of this folding table can slide relative to the two beams of the table frame, when the area of the tabletop needs to be large, the two main tabletops can be moved to the two sides of the crossbeam, and the sub-tabletops are spliced between the two main tabletops to be framed On the beam, a large area tabletop is formed; when the area of the tabletop is small, the auxiliary tabletop can be removed; after the folding table is folded, the auxiliary tabletop can be snapped onto the lower surface of the main tabletop without using It takes up too much volume, so it is easy to use and practical.
