This study evaluates the edgewise bending moment capacity of the four most frequently used middle joints in the upholstered furniture frames. The research included the following joints: Mortise and Tenon, double Dowel, Corner Blocks and double Gusset Plates, designed in the form of middle joints and made of beech and poplar solid wood. The test results indicated that regarding the edgewise bend...

in this study, compressed poplar wood was used to improve the strengths of wooden chairs. these chairs were compared to chairs made from uncompressed poplar wood. wooden chairs were assembled with two types of traditional joints including mortise and tenon and wooden pins joints. the ultimate force was applied from the front to the back of the seat, were recorded according to american library a...

Shrink-fitting, a common bonding technique in metal assemblies, was used for mortise and tenon wood joints. The joints had considerable strength. Shrink-fitting yielded joint strengths comparable to those obtained by using several welded dowels. Increasing the number of welded dowels, however, produced joints of higher strength than those bonded just by shrink-fitting. Combining in the same joi...

The traditional tenon and mortise joint has low processing efficiency a weak theoretical basis, making the structure easy to deform damage, reducing safety, increasing waste of resources. This study aims determine optimum dowel center spacing parameter for chamfered-joint components maximum value strength joints loaded into bending tensile strength. In this study, an integrated optimization met...

Tests were conducted to compare the performance characteristics of school chairs constructed with pinned but unglued round mortise and tenon joints with those of chairs with glued but unpinned joints. Chairs with 0.125-inch cross pins in 0.723-inch diameter tenons developed over 90 percent of the strength of the chairs with glued tenons, whereas chairs with 0.313-inch diameter pins developed on...

Modern solid wood armchairs are developing in the direction of simplicity and lightness, favored by market. However, low mechanical strength connecting joint cantilevered handrails is an issue that needs to be improved. In this study, armrest joints a cantilever armchair made beech (Fagus orientalis Lipsky) were examined. To improve handrail joints, three novel proposed including dovetail tenon...

This paper investigated the bending moment of chair base joints. The ultimate moments (maximum moment), calculated on measured maximum applied loads force), were compared for front leg and rear joints a base. had different angles between stretcher (joint angle) as well tenon lengths (30 mm 32 mm). results tests indicated that test specimen configurations but same tenon-and-mortise geometry, for...
