具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施例的限制。
下面结合附图，说明本发明的较佳实施方式。
请结合图1至图4，本发明所述的工作台100，其包括工作台单元10以及支撑工作台单元10的支架20。工作台单元10具有支撑工件的工作表面，亦即工作台单元10的上表面。支架20用于支撑工作台单元10，包括第一支撑单元22以及第二支撑单元24。
具体的，工作台单元10包括均呈矩形状的主工作台单元12以及辅助工作台单元14。其中，主工作台单元12具有支撑工件的主工作表面120；辅助工作台单元14具有支撑工件的辅助工作台表面140，并且辅助工作台单元14的，背离辅助工作表面140的一侧设有第一安装部141和第二安装部142，第一安装部141和第二安装部142相对设置。第一支撑单元22与第一安装部141连接，第二支撑单元24与第二安装部142连接。
第一支撑单元22包括两个彼此间隔设置的第一支撑腿221以及连接两个第一支撑腿221的梯梁222。当用户踩踏梯梁222时，工作台100亦可作为梯子使用。在此，定义梯梁222的延伸方向为第一方向a，垂直于第一方向a的为第二方向b。第二支撑单元24包括两个彼此间隔设置的第二支撑腿241以及连接两个第二支撑腿241的杆件242。第一支撑腿221上靠近辅助工作台单元14的一端为第一端部2211，远离辅助工作台单元14的一端为第一底部2212；第二支撑腿241上靠近辅助工作台单元14的一端为第二端部2411，远离辅助工作台单元14的一端为第二底部2412。
主工作台单元12与辅助工作台单元14可活动地连接，具有工作位,如图1至图3所示，以及收藏位，如图4所示。
在工作位时，主工作台单元12的主工作表面120与辅助工作台单元14的辅助工作表面140共面。此时，辅助工作台单元14与主工作台单元12一起，共同支撑工件。在收藏位时，辅助工作表面140与主工作表面120不共面。此时，工作台100可作锯木架使用。进一步地，辅助工作台单元14在辅助工作表面140的一侧开设有沿第二方向b延伸的固持槽141。所述固持槽141的尺寸为2*4英寸、2*6英寸、2*8、2*10英寸中的一个，与另一工作台或锯木架配合，即可夹持2*4英寸、2*6英寸、2*8或2*10英寸的工件，以进行锯切加工。
本实施方式中，主工作台单元12围绕平行于第一方向a的第一轴线18可转动地与辅助工作台单元14连接；并且辅助工作台单元14的第一侧边15与第一方向a平行，第三侧边17与第二方向b平行。
工作台100还包括用于将主工作台单元12的主工作表面120保持在与辅助工作表面140共面的工作位和与辅助工作表面140非共面的收藏位的保持装置。
结合图1至图3，保持装置包括设置在所述主工作台单元12下侧,即背离主工作表面120的一侧的 连接梁30。连接梁30呈“U”形，“U”形的未开口一侧可枢转地连接于主工作台单元12，枢转轴线平行于第一方向a。“U”形的开口侧的两个端部分别通过滑动件32连接于第二支撑腿241，本实施方式中，连接梁30的端部通过铆钉与滑动件32连接。请参见图5，所述滑动件32包括滑动部321以及连接滑动部321的定位部322。所述滑动部321套设在第二支撑腿241上，可沿第二支撑腿241的外表面滑动。为了防止滑动部321在沿第二支撑腿241上滑动时，伤及第二支撑腿241的外表面，滑动部321与第二支撑腿241之间设置有防磨层325。防磨层325与滑动部321形锁合的连接。所述定位部322通过转轴323枢接于滑动部321的一个侧壁3211上，且所述定位部322包括分别位于转轴323两侧的锁扣部3221以及解锁部3222，锁扣部3221为通孔。锁销3223穿过通孔3221与定位部322固定连接。本实施方式中，锁扣部3221位于解锁部3222的上侧，在其他实施方式中，锁扣部3221亦可以设置在解锁部3222的下侧。
所述主工作台单元12处于工作位时，锁销3223伸入贯穿侧壁3211的通孔3212后，插设于贯穿第二支撑腿241的固持孔2411内，从而实现连接梁30的固定；若要解除滑动件32与第二支撑腿241的固定，按压解锁部3222。由于杠杆原理，锁扣部3221将被抬起，与锁扣部3221固定连接的锁销3223将脱离固持孔2411，从而允许滑动件32沿第二支撑腿241滑动，亦即主工作台12单元能够切换至收藏位。
从工作位向收藏位切换时，所述主工作台单元12沿第一转轴18相对辅助工作台单元14转动，此时连接梁30的远离主工作台单元12的端部随滑动件32一起沿第二支撑腿241向第二底部2412滑动，直至主工作台单元12转动至抵靠第二支撑腿241的位置。
保持装置还包括卡扣部34，卡扣部34转动地设置在所述主工作单元12的，背离主工作表面120的一侧。卡扣部34与主工作台单元12之间还设置有弹性件(未图示)。图2示出了卡扣部34未受力时，其与主工作台单元12的相对位置关系图。当将主工作台单元12自工作位切换至收藏位时，卡扣部34接触第二支撑腿241而受力旋转，越过第二支撑腿241后，弹性件的作用力将促使卡扣部34回复原状从而卡扣于第二支撑腿241上，从而保证收藏位的稳定。当需要将主工作台单元12自收藏位切换至工作位时，用户按压卡扣部34使其脱开与第二支撑腿241的连接即可。
请结合图1及图2，所述连接梁30上还设有固定件31，所述固定件31用于保持F夹组件。所述主工作台单元12还设有贯穿主工作表面120的固持槽122，所述F夹组件能够被固定于固持槽122内，从而对主工作表面120上的工件进行夹持。F夹组件的具体结构及工作原理是现有技术，此处不再赘述。
请参见图9～图10，工作台100可作梯子使用。对应的，梯梁222能够承受足够的力和力矩。梯梁222的横截面积大于第一支撑腿221的横截面积及第二支撑腿241的横截面积。所述横截面积均是指在各元件的纵长方向上的。并且，所述梯梁222的上表面设有高摩擦系数的防滑部223，可防止用户站立在梯梁222上时，因滑下梯梁222而摔倒，避免安全事故的发生。两个第一支撑腿221呈锥形设置。即，在沿第一方向a上，位于下端的梯梁尺寸大于位于上端的梯梁尺寸。
为方便用户使用梯子的安全性，第一支撑腿221上活动的设置有握持杆26。本实施方式中，所述握持杆26也呈“U”形，如图9所示。其包括握持部261以及分别连接于握持部261两端的杆部262，所述两个杆部262未连接至握持部261的一端分别通过转轴27铰接于第一支撑腿221，从而握持杆26能够相对第一支撑腿221旋转。转轴27的轴线平行于第一方向a。所述握持杆26具有两个极限位置，握持部261翻转至至少部分超出工作表面的第一位置以及握持部261翻转至未超出工作表面的第二位置。 在第一位置和第二位置的切换过程中，握持杆26大致旋转了180度。握持杆26处于第二位置时，所述握持部261部分收容于设置在第一支撑腿221上的凹陷部224内，使得握持杆26未突出于第一支撑腿221的侧面2210，在存储运输状态下不会占用额外的空间。辅助工作台单元14的侧面1410还设置有收容杆部262的收容槽1412，收容槽1412的延伸方向大致与第一支撑腿221的延伸方向平行。握持杆26处于第一位置时，握持杆26的杆部262至少部分容纳于收容槽1412内。
请结合图6至图9，所述工作台100还设置有限位装置，该限位装置能够将握持杆26保持在第一位置，亦即阻止杆部262自收容槽1412脱离。所述限位装置包括可活动地设置在辅助工作台单元14上的限位件41以及开设在握持杆26上的限位孔(未图示)。限位件41包括一对滑块411、固定于滑块411一端的限位部412以及抵压于滑块411与辅助工作台单元14之间的弹性件413。限位部412优选止档销，其轴线方向平行于第一方向a。具体地，所述辅助工作台单元14内部设有收容腔145，收容腔145具有大致平行于第二方向b的第一侧壁1451和第二侧壁1452；滑块411容纳于该收容腔145内，被限制于第一侧壁1451和第二侧壁1452之间。第一侧壁1451开设有贯穿孔(未图示)，止挡销412穿过该贯穿孔沿第一方向a延伸。并且，辅助工作台单元14还开设有供止挡销412穿出的通孔(未图示)。所述滑块411上还设置有操作部4111，该操作部4111穿出设置在辅助工作台单元14上的长槽146以供用户操作。长槽146在沿第一方向a的尺寸大于操作部4111在沿第一方向a上的尺寸。
操作部4111未被操作时，如图6所示。在弹性件413的作用下，滑块411将抵接第一侧壁1451，止挡销412穿出设置在辅助工作台单元14上的通孔，露出辅助工作台单元14的外表面；操作部4111被操作时，具体的，操作部4111被用户带动相向运动时，两滑块411将相向运动，从而止挡销412退回至辅助工作台单元14的内部。
当需要将握持杆26置于第一位置，供用户使用时，旋转握持杆26至杆部262被收容在收容槽1412内即可。在这个过程中，止挡销412首先被杆部262挤压而暂时退回至辅助工作台单元14的内部；当杆部262被收容在收容槽1412后，止挡销412在弹性件413的作用下正好伸入设置在杆部262上的限位孔内。如此，握持杆26处于第一位置的状态即被保持。
当需要放下握持杆26时，用户需克服弹性件413的作用力带动两操作部4111相向运动；从而使止挡销412从握持杆26的限位孔中脱离，即解除了限位装置对握持杆26的锁定。
当然，握持杆26也可以可转动地设置在辅助工作台单元14上，只要满足在第一位置时能方便用户使用；第二位置时能被收纳即可。
搬运、存储的过程中，为减小工作台100的占用空间，工作台100亦可折叠。请参见图2至图3，辅助工作台单元14包括第一工作台单元143以及第二工作台单元144，第一工作台单元143具有第一工作表面1430，第二工作台单元144具有第二工作表面1440。其中，第一支撑单元22与第一工作台单元143固定连接，第二支撑单元24与第二工作台单元144固定连接；并且第一工作台单元143围绕平行于第一方向a的第二轴线19可转动地与第二工作台单元144连接。也就是说，第一支撑单元22能够围绕平行于第一方向a的第二轴线19相对于第二支撑单元24转动。
当然在其他的实施方式中，工作台还可以设置为：第一支撑单元可转动地与第一安装部连接，转动轴线平行于所述第一方向a；第二支撑单元可转动地与第二安装部连接，转动轴线平行于所述第一方向a。如此，第一支撑单元亦能够相对于第二支撑单元转动。
工作台100还包括止动装置，用于限制第一支撑单元22和第二支撑单元24之间的相对转动。
本实施方式中，止动装置为连接第一支撑单元22以及第二支撑单元24的连杆机构25。连杆机构25包括枢转连接的第一连杆251和第二连杆252。第一连杆251为两个大致呈扁平的“凹形”的杆，两端分别铰接于第一支撑腿221和第二连杆252，铰接轴平行于第一方向a；第二连杆252呈“U”形，且“U”形开口端朝向第二支撑单元24设置；第二连杆252的开口端分别铰接于两个第二支撑腿241，铰接轴平行于第一方向a；藉此，所述第一支撑单元22与所述第二支撑单元24能够通过第一连杆251与第二连杆252的相互转动而相互靠近或远离，使得工作台100具有展开位，如图1至图4所示，以及折叠位，如图11至图12所示。当需要将工作台100从展开位切换至折叠位时，用户只需操作第二连杆252的未开口端，带动第二支撑单元24朝靠近第一支撑单元22的方向转动即可。
特别的，在工作台100处于展开位，且主工作台单元12处于收藏位时，整个工作台100呈截头的“A”结构，如图4所示。其中，所述第一支撑单元22和所述第二支撑单元24对应于“A”的支腿，所述辅助工作台单元14对应于截头“A”的顶部，所述连杆机构25对应于“A”的交叉件。
为进一步丰富工作台100的功能模式，工作台100还设置有滚动装置50。滚动装置50设置在第一支撑单元22或第二支撑单元24上；当滚动装置50接触地面时，工作台100可作手推车使用。
具体的，杆件242的两端分别设置有支撑轴；滚动装置50为一轮滚轮，滚轮50分别套设在支撑轴上，能够围绕支撑轴转动。杆件242相对于第二支撑腿241的位置以及滚轮50的尺寸大小被构造为：当将工作台100展开时，滚轮50与支撑工作台的平面，诸如地面，不接触。
请结合图2、图9及图11，工作台100还包括连接于杆件242的支撑件60，所述支撑件60包括主体部62、与主体部62固定连接的枢转部64以及锁紧部66。所述枢转部64套设于杆件242上，可围绕杆件242转动；锁紧部66优选为一旋钮，旋钮66能够旋紧或旋松从而将主体部62固定于杆件242上的某一旋转位置。所述主体部62大致为呈“Z”形的片状，从而能够提供一个呈“L”形的支撑面，所述支撑面包括相互垂直的第一表面621及第二表面622。值得注意的是，主体部62类似于叉车铲脚，可铲起放置物品的铲板。
作工作台使用时，请参见图1-图3。在保持装置的作用下，主工作台单元12的主工作表面120与辅助工作台单元14的辅助工作表面140共面，共同支撑工件；同时握持杆26处于未超出工作表面，被第一支撑腿221的凹陷部224收容的第二位置。
作锯木架使用时，请参见图4，主工作台单元12处于主工作表面120与辅助工作表面140不共面的收藏位。
作梯子使用时，请参见图9及图10，此时握持杆26旋转至超出辅助工作表面的第一位置。用户双脚踩在梯梁222上，防滑部223提供了足够大的静摩擦力，以防止用户滑倒。握持杆26可供用户抓握，特别是在用户向上一层梯梁222移动时或用户在顶层梯梁222进行工作时提供助力。同时，主工作台单元12可根据用户需要处于与辅助工作台单元14共面或不共面的位置。特别的，参照图10，主工作台单元12的主工作表面120可作为一个支撑台面放置一些常用工具，便于用户在梯子上时直接使用，而无需走下梯子或另外一人辅助。譬如，在用户进行粉刷墙壁的作业时，主工作表面120可用于放置油漆桶，用户握紧握持杆26同时略微下蹲即可将油漆刷伸入油漆桶内蘸取油漆。主工作表面120上还可以设置限位凹槽，用于防止放置在主工作表面120上的油漆桶或其他物体跌落，如图15所示。主工作表面120 上设置有两个圆环形的凹槽123和124，分别用于限制不同尺寸的物体。大圆环123的外径168㎜，内径是138㎜。小圆环124的外径是109㎜，内径是77㎜。更优选的，握持部261上可活动地设置有工具托盘，用于放置小尺寸工具。
以图9所示的工作状态为初始状态，操作第二连杆252运动，使得第二支撑单元24连同第二工作台单元144一起朝向第一支撑单元22转动；同时，拧松锁紧部66，使枢转部64及主体部62旋转至第一支撑面621与第一支撑腿221的侧面2210共面的位置；再拧紧锁紧部66，以使两者保持共面状态，从而得到图11所示的状态。此时，此时调整工作台100的角度，使得工作台100上有且仅有滚轮50接触地面，即可作手推车使用，此处，握持杆26作为手推车的推杆使用。优选的，梯梁222背离杆件242的侧面2220、第一支撑腿221背离第二支撑腿241的侧面2210以及第一表面621共面，从而形成一个更大尺寸的总支撑面，主体部62的第二表面622作为辅助支撑面及挡止面使用，可避免货物自推车掉落。在工作台100作为手推车使用时，总支撑面上的货物会对第一支撑腿221及梯梁222施加一个指向第二支撑腿241的作用力，从而保证了折叠结构的稳定。
以图11为初始状态，将握持杆26自第一位置调节至第二位置，并将支撑件60调节至原状态，即图3的状态，即可获得如图12所示的处于存储状态下的工作台100。此时主工作表面120平行于第一支撑腿221及第二支撑腿241的延伸方向。支撑件60以及部分握持杆26均位于第一支撑腿221及第二支撑腿241围成的空间内，未占用额外的空间。第一工作台单元143可作为握持杆供用户抓握，用户只要将手放置于第一工作台单元143的底面，即可拿起工作台100，底面作为抓握面。
请结合图13及图14，本发明还提供另一种结构的支撑件60’，所述支撑件60’包括转动连接于第二支撑腿241的枢转部62’、连接于枢转部62’两端的支撑部64’、连接于支撑部64’的尾部66’以及固定连接于枢转部62’的锁扣部68’。第一支撑腿221的侧面2210及梯梁222的侧面2220共面，形成支撑物品的总支撑面，支撑部64’用于辅助支撑且可避免物品掉落。支撑部64’的数量可根据需搬运的物品的尺寸来确定，物品尺寸越小，要求支撑部64’的数量越多。若要搬运大件物品，设置两个支撑部64’即可。当然，支撑部64’也可放置支撑板以支撑工件。
锁扣部68’设有第一缺口681’，所述尾部66’上设有第二缺口661’。所述第一缺口681’用于对支撑件60’进行限位，所述第二缺口661’在使用时具有一定离地高度，可用于悬挂一些物品，譬如花盆等。
作手推车使用时，支撑件60’围绕第二支撑腿241旋转，直至所述第一缺口681’与设置于第一支撑腿221上的锁销225卡合，卡合后锁销225阻止支撑件60’进一步旋转。此时，第一支撑腿221与第二支撑腿241通过锁扣部68’以及锁销225稳定地连接，保证了折叠后的手推车结构的稳定性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
